Detailed Description
As known from the background art, the existing test system for testing the power performance of the airborne equipment is huge and complex, often needs manual operation, and has complex test implementation, high difficulty and serious resource waste.
It was found by analysis that the above problems occur at least because: the power performance test of the airborne equipment mainly comprises the steps of simulating an aircraft power supply to output a working power supply to the airborne equipment through a simulation power supply equipment according to test requirements, simulating electric equipment hung by the airborne equipment through a simulation load equipment so as to simulate a scene of carrying operation of the airborne equipment, controlling start and stop of the simulation power supply equipment and the simulation load equipment by utilizing an upper computer, and simultaneously collecting and monitoring parameters such as power supply, current, power and the like related to input and output of the airborne equipment so as to realize the test of the airborne equipment. In the test process, the analog power supply device and the analog load device are independent and fixed, and the combination mode of the analog power supply device and/or the analog load device needs to be designed according to specific test requirements and then manually combined to provide the power supply and the load required by the test. Thus, there is a need to provide a bulky and complex test system that otherwise fails to support the combination of analog power devices and/or analog load devices, and fails to provide the required power and load. And moreover, a tester is required to watch, so that the simulation power supply equipment and/or the simulation load equipment are combined in time to perform testing, the automatic implementation cannot be realized, and the manpower and material resources are seriously wasted.
In order to solve the above technical problems, an embodiment of the present application provides a test system, which does not use a fixed analog power supply device and an analog load device, but uses an analog power supply module capable of flexibly providing a corresponding power supply signal according to a first control signal, and an analog load module capable of flexibly providing a corresponding load according to the first control signal. Based on the change, the test system can run test control software deployed in the test control center through the test control center module during testing, so that the test control software outputs first control signals for controlling the analog power supply module and the analog load module, and then the analog power supply module and the analog load module respond to the first control signals to provide required power supply signals and loads for the test to the airborne equipment module, so that the test is performed according to the test requirements, the dependence on manpower in the test process is reduced, the automatic test is facilitated, the complexity and difficulty of the test are reduced, and the resource waste is reduced.

In some embodiments, referring to fig. 1, a test system includes a test control center module 100 with test control software deployed therein configured to run the test control software to output a first control signal; the analog power module 200 is connected with the test control center module 100 through a switch, and is configured to receive a first control signal output by the test control center module 100 and provide a corresponding power supply signal according to the received first control signal; the simulated load module 300 is connected with the test control center module 100 through a switch, and is configured to receive a first control signal output by the test control center module 100 and provide a corresponding load according to the received first control signal; the on-board equipment module 400 is respectively connected with the analog power supply module 200 and the analog load module 300 and is configured to work with the load provided by the analog load module 300 as a load according to the power supply signal provided by the analog power supply module 200; the power performance acquisition module 500 is respectively connected with the test control center module 100 and the on-board device module 400, and is configured to acquire power performance parameters in the working process of the on-board device module 400, and output the power performance parameters to the test control center module 100, so that the test control center module 100 generates a test result according to the power performance parameters.
In this way, the test system is provided with the analog power supply module 200 capable of flexibly providing the corresponding power supply signal according to the first control signal, and the analog load module 300 capable of flexibly providing the corresponding load according to the first control signal, so that when the test system is used for testing, the test control software deployed by the test control center module 100 is arranged, the corresponding first control signal is output to control the analog power supply module 200 and the analog load module 300 to provide the required power supply signal and load, the required power supply signal and load can be provided without manually combining a fixed power supply and a fixed load, the power input control of the airborne equipment and the real-time monitoring, acquisition and data transmission of the voltage performance parameters can be realized, the dependence on manpower in the test process is reduced, the automatic test is facilitated, the complexity and difficulty of the test are reduced, and the resource waste is reduced.
In addition, the analog power supply module 200 and the analog load module 300 are connected with the test control center module 100 through a switch, so that the test control center module 100, the analog power supply module 200 and the analog load module 300 are located in the same local area network (Local Area Network, LAN), and thus the first control signal can be more efficiently and stably transmitted among the test control center module 100, the analog power supply module 200 and the analog load module 300, and the test can be more efficiently and stably performed. Especially for the test which needs periodic test and has strong timeliness, the test result is more accurate, and the test requirement is more met.
In some embodiments, the first control signal may carry a single parameter, such that a test is performed based on the first control signal; the first control signal may also carry a set of parameters, so that multiple tests are performed based on the first control signal, and even a test for a power performance parameter is completed, which will not be described in detail herein.
In some embodiments, the power performance parameters may include one or more of the following: output voltage accuracy, output current accuracy, input regulation, load regulation, frequency, ripple, dynamic response time, efficiency, power factor, overvoltage protection, overcurrent protection, overtemperature protection, input failure, etc.
It will be appreciated that the test logic may be different when different power performance parameters are collected, and that the collection means required to be used may also be different.
Based on this, in some embodiments, as shown in fig. 2, the power performance acquisition module 500 may further include several access interfaces for accessing the acquisition device, where the several access interfaces are integrated into a chassis, i.e., the rectangle of the periphery in fig. 2, and the access interfaces, i.e., the rectangle shown in phantom in fig. 2. The test control center module 100 is further configured to update the test control software to target software that supports testing of the on-board equipment module in terms of power performance parameters that can be acquired by the at least one acquisition device after the at least one acquisition device is accessed through the plurality of access interfaces.
Thus, when the test system does not have the power performance parameters required by test collection, one or more interfaces of the interfaces provided by the power performance collection module 500 can connect the collection device for collecting the corresponding power performance parameters to the power performance collection module 500, so that the power performance collection module 500 has the capability of collecting the corresponding power performance parameters of the airborne equipment module 400 in the test process. And the test control center module 100 also updates the test control software correspondingly, so that the test control center module 100 can test one or more power performance parameters of the power performance parameters which can be acquired by the at least one acquisition device which is accessed to the power performance acquisition module 500 through the updated test control software and can acquire the power performance parameters corresponding to the at least one acquisition device which is accessed to the power performance acquisition module 500 when required. The test system has the advantages that the expansion of the test content which can be realized by the test system is realized, the test system can adapt to test verification of new airborne equipment or new types of airborne equipment, various test requirements are favorably met, the realization difficulty is low, the change to the test system is less, the compatibility is better, the failure rate is lower, the test process of the airborne equipment is accelerated, the test period is shortened, the research and development efficiency is improved, and the cost is saved.
In some embodiments, the several access interfaces may also be standard generic interfaces, thereby facilitating better access to various vendors' acquisition devices and better avoiding incompatibility problems.
It should be noted that, in the above embodiment, the plurality of access interfaces are integrated in the chassis, which is beneficial to better protecting and managing the plurality of access interfaces. In other embodiments, several access interfaces may be disposed on each circuit board of the power performance acquisition module 500, and are not integrated, which is not described in detail herein.
It should be noted that, the updating of the test control software may be implemented by searching and downloading corresponding software in a preset software library, or may be implemented by notifying a tester to input corresponding software, which is not described in detail herein.
In some embodiments, referring to fig. 3, the test system further includes a temperature control module 600, the temperature control module 600 being connected to the test control center module 100 and to the on-board equipment module 400 through a switch and configured to receive a first control signal output by the test control center module 100 and to start operation according to the received first control signal, so as to output a second control signal after detecting that the temperature of the on-board equipment module 400 deviates from the operating temperature; the on-board device module 400 is further configured to receive the second control signal output by the temperature control module 600, and adjust the current operating state according to the received second control signal, so as to restore to the operating temperature.
In this way, after the temperature of the on-board equipment module 400 deviates from the working temperature, the temperature control module 600 will generate a second control signal, so that the on-board equipment module 400 is controlled to adjust the working state by the second control signal, and the temperature is restored to the working temperature, thereby ensuring the normal operation of the on-board equipment module 400. That is, the temperature protection is provided for the on-board equipment module 400, which is beneficial to better simulate the actual scene to be applied of the on-board equipment module 400, and improves the reliability and accuracy of the test.
In some embodiments, the on-board device module 400 is further configured to trigger a step of operating with the load provided by the load module 300 as a load according to the power supply signal provided by the analog power supply module 200 after the temperature control module 600 starts operating; the temperature control module 600 is also configured to end operation after the on-board equipment module 400 has ended operation.
In this way, the temperature control module 600 is turned on before the on-board equipment module 400 starts to work and turned off after the on-board equipment module 400 ends to work, so that the temperature protection provided by the temperature control module 600 is guaranteed in the whole working process of the on-board equipment module 400, the working temperature of the on-board equipment module is further guaranteed, and the on-board equipment module 400 is always in a normal working state in the testing process.
It should be noted that the above embodiments are merely further illustrative of the operation manner of the temperature control module 600, and in some embodiments, it may also be considered that the temperature of the on-board device module 400 is not higher than the operation temperature for a certain period of time, and the temperature control module 600 is configured to be turned on for a certain period of time after the on-board device module 400 starts to operate, etc.
In some embodiments, each of the target modules in the test system is configured to detect target information before the test control center module 100 outputs the first control signal; the target information includes whether power up and/or interface access is accurate, and the target modules include at least one of a test control center module 100, a simulated power supply module 200, a simulated load module 300, a power performance acquisition module 400, and an on-board device module 500.
In this way, before the test control center module 100 outputs the first control signal, that is, before the test is performed, the target information is detected, so that the test is performed under the condition that the target information is normal, the test under an abnormal state can be avoided, the fault protection is favorably provided for the test system, and the accuracy of the test is improved.
That is, the test system has the functions of power-on self-checking, interface identification and the like, so that the on-line self-checking of the internal modules of the test system and the correctness detection of the interface connection of the system can be realized before the test system operates.
In some embodiments, the target information includes whether the interface access is accurate, each of the target modules includes at least two interfaces, and different resistive loads are connected to different types of interfaces in the at least two interfaces; each of the target modules is further configured to determine an object accessed by the at least two interfaces based on the resistances on each of the at least two interfaces to determine whether the object accessed by the at least two interfaces is accessed correctly.
It will be appreciated that when at least two interfaces, i.e. at least two types of interfaces, are included in the same module, there may be access errors. According to the embodiment, different resistive loads are set for different interfaces to be connected, so that different resistance values are brought after different interfaces are accessed, the type of the currently accessed interface can be determined through the specific resistance values, and whether the interface is matched with an object to be accessed by the module in the current test requirement or not is determined, so that whether the access is correct or not is determined. That is, the high-efficiency detection of whether the access interface is accurately accessed is realized through the concise resistive load setting, and the detection method does not need other equipment, devices and the like to assist, thereby being beneficial to reducing the realization difficulty and cost of detection.
In some embodiments, the power performance acquisition module 500 is connected to the test control center module 100 via a bus.
In this way, the communication between the power performance acquisition module 500 and the test control center module 100 can be maintained at a higher efficiency, so that the test data can be more efficiently and rapidly transmitted, and the test efficiency is improved.
In some embodiments, the test control center module 100 is further configured to, in an automatic mode, periodically trigger the step of running the test control software and periodically end the running of the test control software.
Therefore, the timing test is realized through the timing operation of the test control software, so that the test can be performed under the condition of no supervision, and the dependence on manpower is further reduced.
In some embodiments, the test control center module 100 is further configured to run test control software according to user instructions or a preset test plan to output a first control signal.
In this way, the test control center module 100 can support manual testing based on user instructions, and can also support automatic testing based on a preset test plan, which provides various implementation manners, and is beneficial to better meeting test requirements in different scenes.
It should be noted that, the user instructions and the preset test plan in the above embodiment may be used to set the parameters related to the analog power module 200, the analog load module 300, the temperature control module 600, and the like, such as voltage, frequency, current, duration, temperature, and the like, during the test, and at the same time, at least one power performance parameter to be tested is selected according to the requirement, so that the test control center module 100 generates the corresponding first control signal based on the first control signal.
In some embodiments, the power performance acquisition module 500 is integrated with the test control center module 100 to more efficiently transfer test data over the bus.
It should be noted that, in the embodiment of the present application, the "first control signal" and the "second control signal" are mainly used to distinguish whether the control signal is output by the test control center module 100 or the temperature control module 600, and are not specifically limited, for example, the first control signal output by the test control center module 100 to the analog power module 200 is different from the first control signal output by the analog load module 300 in the essential content, and the first control signal is used to indicate the power supply size and the type required by the analog power module 200, and the second control signal is used to indicate the load size required by the analog load module 300.
It should be further noted that, in order to highlight the innovative part of the present application, no element that is not very close to solving the technical problem presented by the present application is introduced in the present embodiment, but it does not indicate that no other element is present in the present embodiment.
The embodiment of the application also provides a testing method which is applied to the testing system in any embodiment. This will be described in detail below with reference to fig. 4 to 5. Fig. 4 is a flowchart of a testing method provided by an embodiment of the present application, and fig. 5 is another flowchart of a testing method provided by an embodiment of the present application.
In some embodiments, as shown in fig. 4, the test method includes:
in step 401, the test control center module runs test control software to output a first control signal to the analog power supply module and the analog load module.
In step 402, the analog power module provides a corresponding power supply signal to the on-board device module according to the received first control signal.
In step 403, the load simulating module provides a corresponding load for the airborne equipment module according to the received first control signal.
In step 404, the on-board device module works with the load provided by the analog load module as a load according to the power supply signal provided by the analog power supply module.
Step 405, the power performance acquisition module acquires the power performance parameters in the working process of the airborne equipment module, and outputs the power performance parameters to the test control center module for the test control center to generate a test result according to the power performance parameters.
It is to be noted that this embodiment is a method embodiment corresponding to the system embodiment, and this embodiment may be implemented in cooperation with the same embodiment. The related technical details mentioned in the system embodiment are still valid in this embodiment, and in order to reduce repetition, they are not described here again. Accordingly, the related technical details mentioned in the present embodiment can also be applied to the system embodiment.
To facilitate a better understanding of the test method provided by the embodiments of the present application, a specific description thereof will be given below with reference to fig. 5.
As shown in fig. 5, the test method is implemented as follows:
the test control center module initializes the test control software deployed inside.
After the test control software is initialized, the test control center module determines whether to test in an automatic mode according to a user instruction.
If testing is performed in the automatic mode, the test control center module also needs to determine whether there are on-duty testers. When the on-duty tester exists, the on-duty tester can set the performance parameters of the power supply to be tested; when no on-duty tester exists, the test control center module can independently arrange a test plan or read a preset test plan, determine the time for starting at fixed time and the time for ending the work at fixed time, and set the performance parameters of the power supply to be tested according to the time.
If the test is not performed in the automatic mode (i.e. in the manual mode), the test control center module sets the power performance parameters to be tested according to the instructions issued by the testers in real time.
After setting the power performance parameters to be tested, the test control center module determines the type of the test to be performed according to the number of the types of the power performance parameters to be tested, wherein the power performance parameters to be tested are one item, and the test type is single item test; when the power performance parameters to be tested are multiple, the test type is multiple visual tests.
The test control center module then generates a first control signal to indicate the sequence of power supply signals and the sequence of loads that the analog power supply module and the analog load module are required to provide.
The analog power supply module and the analog load module continuously provide power supply signals and loads for the airborne equipment module according to the received first control signals.
And the airborne equipment module works by taking the load provided by the analog load module as a load according to the power supply signal provided by the analog power supply module.
The power performance acquisition module acquires corresponding power performance parameters and outputs the power performance parameters to the test control center module.
The test control center module stores the received power performance parameters.
When the test is performed in the automatic mode, the analog power supply module and the analog load module respond to the first control signal and generate a plurality of power supply signals and a plurality of loads, and after the on-board equipment module works, the current test is ended until the next timing test is started or the next test task is performed. When the test is not performed in the automatic mode, on the basis of the above, a tester is required to instruct the test control center module whether to exit the test, if the tester instructs to exit the test, the current test is ended, otherwise, the step of determining whether to perform the test in the automatic mode is further required to be returned.
It should be noted that the above test may be a single test or a cyclic test, which may be determined by test control software or indicated by a tester, and will not be described in detail herein.
It should be noted that, the above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, which is within the protection scope of the present patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the application and that various changes in form and details may be made therein without departing from the spirit and scope of the application.
