The telemetry transmitter selected as the signal relay device in the fifth step is specifically as follows: a telemetry transmitter simultaneously located within the area of wireless communication and the telemetry reception area of the telemetry receiving station.
A telemetering transmitter real-time dynamic configuration device comprises a telemetering transmitter arranged on a telemetering target, wherein a data receiving and transmitting management module is arranged in the telemetering transmitter, the data receiving and transmitting management module is connected with a wireless transmitting module and a wireless receiving module, and the wireless transmitting module and the wireless receiving module are connected with a transmitting antenna through a duplexer;
the wireless transmitting module is used for receiving telemetering data remotely transmitted by the telemetering receiving station;
the data receiving and transmitting management module is also connected with a communication interface module.
The invention provides a method and equipment for dynamically configuring a telemetering transmitter in real time, which mainly relate to dynamic configuration methods such as configuration parameters, working parameters and the like, and improvement of a wireless communication strategy.
The invention provides a telemetering transmitter with a real-time dynamic configuration function, which belongs to a component of the whole telemetering system, and can manage telemetering tasks of a plurality of telemetering transmitters through a radio command sent by a telemetering receiving station management system.
The management system in the telemetering receiving station monitors the frequency spectrum resource use condition of a telemetering airspace in real time, determines the allowed frequency resource, dynamically allocates configuration parameters such as working frequency points for each telemetering transmitter, and configures the working parameters of each telemetering transmitter in real time according to the quality of a telemetering communication link, such as a telemetering data acquisition mode.
The telemetering transmitter provided by the invention is specifically installed on each telemetering target, acquires telemetering target data and transmits the telemetering target data in a wireless mode.
The telemetering transmitter can set working state parameters (sampling strategies, working modes and the like) and telemetering configuration parameters (frequency points, power and the like) of the transmitter through a wired or wireless communication interface, and the set parameters are not lost when power failure occurs, so that the working state parameters and the configuration parameters are preset; the telemetering transmitter has a real-time dynamic configuration function, and the configuration loading working parameters comprise information such as acquisition channel number, sampling rate, sending period, sending code rate and the like; the configuration parameters that can be dynamically configured and loaded include: code rate, frequency point, transmitting power, whether to encrypt, key parameters, and the like; recognizable command parameters include: networking calling, starting data acquisition and transmission and the like; when the telemetering transmitter is used for realizing an aerial multi-target complex telemetering data acquisition and transmission system, the parameter types and command types can be expanded according to actual needs.
The telemetry transmitter has a real-time dynamic configuration function and mainly comprises a conventional mode and a networking mode, the networking mode can be divided into a direct starting mode and a controlled starting mode, and a mode association diagram is shown in figure 2.
The conventional mode is a working mode for a common transmitter and is applied to a telemetering scene of a telemetering-free receiving station management system, and after the transmitter is powered on, telemetering target data acquisition and telemetering data transmission are carried out according to preset working state parameters (a sampling strategy, a working mode and the like) and configuration parameters (a code rate, a frequency point, transmission power and the like).
The networking mode is applied to a scene needing networking through a remote measuring receiving station management system, a remote measuring transmitter does not acquire and send remote measuring data within a set time after being electrified, but enters a monitoring state of a wireless signal, waits for a radio communication instruction of the management system, performs real-time configuration loading of parameters such as frequency points and modes, and performs instruction reply according to a communication protocol; if the information interaction is not completed before the specified time or the starting marks of confirmation and judgment of some physical and digital characteristic signals of the telemetering target arrive, wireless data transmission is carried out according to preset working state parameters (sampling strategies, working modes and the like) and configuration parameters (code rate, frequency points, transmitting power and the like).
In the networking mode, the telemetering transmitter works in a direct starting mode or a controlled starting mode by identifying a wireless communication instruction, and when the telemetering transmitter works in the direct starting mode, the telemetering transmitter immediately starts to acquire and send telemetering target data after completing parameters such as frequency points and the like through wireless controlled loading; when the remote sensing target data acquisition and transmission device works in a starting controlled mode, acquisition and transmission of the remote sensing target data are not carried out until the remote sensing target data acquisition and transmission device is started after wireless controlled loading finishes parameter configuration such as frequency points and the like, and the acquisition and transmission of the remote sensing target data are started after a specified time, a wireless communication instruction (a remote sensing data transmission instruction) or starting marks such as confirmation and judgment of certain physical and digital characteristic signals of the remote sensing target are waited.
In order to avoid the collision of airspace signals in the response process, the telemetering transmitter adopts a command response anti-collision mechanism, utilizes the unique identification code of the telemetering transmitter to generate random response time through an algorithm, and effectively avoids the collision of the airspace signals through the difference of delayed random response time.
After the telemetering transmitter is configured by parameters, the telemetering transmitter works in a relay mode, the telemetering transmitter respectively determines a receiving frequency point and a transmitting frequency point through parameter configuration, enters a monitoring state of a wireless signal after being electrified, receives and analyzes telemetering data or a radio instruction, and sends out the received data and instruction according to parameter configuration requirements such as a specified modulation mode, a code rate and the like.
Based on the configuration of the transmitter, when in use, the following embodiments can be implemented:
example 1: the telemetry transmitter is compatible with a common telemetry transmitter for use:
the telemetering transmitter is set to be in a conventional mode through a wired or wireless communication mode before testing, a radio receiving function is not needed during testing, the telemetering transmitter is not managed by a telemetering receiving station, and telemetering data signals are continuously transmitted according to preset configuration parameters after being powered on.
Example 2: configuring parameters of a controlled telemetry transmitter in a wireless dynamic loading mode:
the telemetering transmitter adopts a wireless command analysis real-time loading mode, a typical mode is adopted for operation in the embodiment, and the types of interactive commands can be increased according to needs in the specific implementation process;
as shown in fig. 3, a telemetry transmitter (2, 3,4 in fig. 3) is installed on each telemetry target, and each telemetry transmitter is set to be in a networking mode through a wired or wireless communication mode before the test;
in the test, the plurality of telemetering transmitters (2, 3 and 4 in fig. 3) are all located in a wireless communication coverage area, and are in a networking mode after being powered on, telemetering data is not sent, and a networking broadcast instruction sent outwards by a telemetering receiving station is waited to be monitored.
After receiving a networking broadcast response instruction of each telemetering transmitter, the telemetering receiving station sends the currentidle configuration parameter 1 to the telemetering transmitter through a networking instruction, and after receiving the networking instruction, the telemetering transmitter sends a configuration parameter loading completion result to the telemetering receiving station through a networking response instruction, so that the dynamic allocation of configuration parameters of each telemetering transmitter is realized;
meanwhile, the telemetry receiving station establishes a wireless communication link with thetelemetry transmitter 3 and thetelemetry transmitter 4 within a specified time, theidle configuration parameters 2 of the current airspace are sent to thetelemetry transmitter 3, theconfiguration parameters 3 are sent to thetelemetry transmitter 4, and the plurality of telemetry transmitters start to work according to the configuration parameters which are dynamically loaded, so that parallel tasks among the plurality of telemetry transmitters are realized, frequency point mutual interference among the plurality of telemetry transmitters and other radio equipment in the airspace is avoided, and the execution capacity and the working efficiency are improved.
Example 3: loading working state parameters of the controlled telemetering transmitter in a wireless dynamic loading mode:
as shown in fig. 4, a multi-target real-time telemetry system is specifically composed of a plurality of telemetry transmitters (2, 3,4,5, 6, 7, 8, 9, 10 in the figure) and a telemetry receiving station with a parameter loading function, and in this embodiment, the method for dynamically loading configuration parameters inembodiment 2 is also adopted.
When the total number of targets in the telemetry task is more than the number of channels of receivers in the telemetry receiving station, the receiving capability of the telemetry receiving station is saturated at the moment, and the telemetry receiving station cannot adapt to more and more complex acquisition and transmission networks of a telemetry system; according to the configuration method of the embodiment, a time-sharing control method is adopted, so that the data receiving capacity can be improved, and the specific process is as follows:
the method comprises the steps of definingtelemetering transmitters 2,3 and 4 as telemetering transmitters of the same acquisition type, definingtelemetering transmitters 5, 6 and 7 as telemetering transmitters of the same acquisition type, definingtelemetering transmitters 8, 9 and 10 as telemetering transmitters of the same acquisition type, setting the telemetering transmitters into a networking mode in a wired or wireless communication mode before a test, dynamically loading configuration parameters for thetelemetering transmitters 2 to 10 according to a configuration method inembodiment 2,loading configuration parameters 1 in sequence for thetelemetering transmitters 2,3 and 4,loading configuration parameters 2 in sequence for thetelemetering transmitters 5, 6 and 7,loading configuration parameters 3 in sequence for thetelemetering transmitters 8, 9 and 10, and continuously keeping in an external wireless instruction monitoring state after all the telemetering transmitters load the configuration parameters to actively acquire telemetering data for transmission so as to receive acquisition and transmission commands.
The remote sensing receiving station periodically sends an acquisition command, works according to a time sequence, firstly sends the acquisition and sending command of theremote sensing transmitter 2, the command has an identification number ID of theremote sensing transmitter 2, theremote sensing transmitter 2 starts to acquire channel data after receiving an acquisition instruction, the remote sensing data is sent according to aconfiguration parameter 1 after the acquisition is finished, and the remote sensing receiving station distinguishes and stores the remote sensing data according to the number of the transmitter;
then sending an acquisition and sending command of atelemetering transmitter 3, starting to acquire channel data after thetelemetering transmitter 3 receives an acquisition instruction, sending telemetering data according toconfiguration parameters 1 after the acquisition is finished, and repeating the steps, wherein the telemetering receiving station receives telemetering data of a plurality of targets in a time-sharing mode; in the operation process, the configuration parameters of the telemetering transmission of a plurality of telemetering targets can be different, such as the transmission code rate, the transmission frequency point, the transmission power and the like, and the complex data recovery management suitable for different telemetering targets in the same time and the same airspace can be realized.
Example 4: using the controlled telemetry transmitter as a repeater:
in this embodiment, the method of dynamic loading of configuration parameters inembodiment 2 is also adopted;
in this case, when the target in the telemetry task is too far away from the telemetry receiving station, the receiving capability of the telemetry receiving station is exceeded; due to the influence of factors such as terrain and the like, the telemetering ground station cannot receive telemetering data in a certain time period, and the telemetering transmitter is used as a signal relay device, so that the data receiving capacity can be improved;
as shown in fig. 5, a telemetry transmitter (3, 4,5 in fig. 5) is installed on a telemetry target and is in a wireless communication area range, and is out of a telemetry data receiving area of a telemetry receiving station due to high telemetry data code stream, and the telemetry transmitter (2 in fig. 5) is simultaneously in the wireless communication area range and the telemetry receiving area range of the telemetry receiving station, and at this time, the telemetry transmitter can work in a relay mode by loading configuration parameters of the telemetry transmitter, and the data of thetelemetry transmitter 2 is forwarded to the telemetry receiving station;
thetelemetry transmitters 3 and 5 are installed on a telemetry target and are positioned in the range of a wireless communication area; because the code stream of the telemetering data is high and is outside the telemetering data receiving area of the telemetering receiving station, thetelemetering transmitter 2 is used as a relay point and is simultaneously positioned in the wireless communication area range and the telemetering receiving area range of the telemetering receiving station, the telemetering transmitters 3-5 are simultaneously positioned in the wireless communication area range of thetelemetering transmitter 2, but the telemetering receiving station can directly receive the data because thetelemetering transmitter 4 is positioned in the testing coverage area of the telemetering receiving station. The telemetry receiving station may then forward the data from thetelemetry transmitters 3 and 5 to the telemetry receiving station by loading the configuration parameters of therelay transmitter 2 to operate in relay mode.
Taking the example of forwarding the data of thetelemetry transmitter 3, after thetelemetry transmitters 2 and 3 enter the wireless communication coverage area, the telemetry receiving station loads the configuration parameters and the working parameters of thetelemetry transmitter 2 according to the method for dynamically loading the configuration parameters in theembodiment 2, and simultaneously loads the configuration parameters of thetelemetry transmitter 3 according to the parameter adaptability of thetelemetry transmitter 2, thereby realizing frequency conversion transmission.
When thetelemetering transmitter 2 enters the telemetering data receiving area, the telemetering receiving station directly receives data, and data splicing is carried out through data processing software after the task is finished.
According to the method provided by theembodiment 4, the telemetering system adopts a relay method to transmit and receive data, so that the problem that the data volume cannot be further reduced by methods such as reducing the sampling rate and the like is solved, the air data code rate is reduced, and the telemetering distance is increased.
