themobile terminal 603 is further configured to send test success information to thecloud platform 601 if the test result is that the test passes;

Through the above description, it is not difficult to find that the internet of things interactive system provided by the embodiment provides a specific network access test method, the whole network access test process is operated based on the internet of things of the elevator, and theelevator terminal 602 and themobile terminal 603 are jointly used for carrying out the elevator test action, so that the test efficiency of the network access test performed on the special equipment of the elevator is ensured, and the technical problem of low efficiency of the elevator network access test is solved.
Meanwhile, the specific technical details of the network access testing link are further refined.
Further, themobile terminal 603 is further configured to acquire user identity information and send the user identity information to thecloud platform 601;
thecloud platform 601 is further configured to generate an elevator test record according to the user identity information and the test success information.
Further, thecloud platform 601 is further configured to generate a network access success instruction when receiving the network access information of theelevator terminal 602, and send the network access success instruction to theelevator terminal 602;
and theelevator terminal 602 is configured to perform a test prompt behavior in a first preset prompt manner when the network access success instruction is received.
It can be understood that after the elevator master control board and theelevator terminal 602 complete the network entry, the functional test link of the elevator can be entered.
In the functional test link of the elevator, after the network access information is generated at thecloud platform 601, a network access success command can be correspondingly generated and notified to theelevator terminal 602 to remind field personnel to start elevator test operation.
The network access information is information generated corresponding to network access operation, and the network access information comprises elevator parameters.
Wherein, can be equipped with the suggestion pilot lamp on theelevator terminal 602, first preset suggestion mode can be the scintillation of suggestion pilot lamp.
Specifically, the flashing of the prompt indicator light can inform field personnel that App can be logged in to carry out the test operation of the internet of things function of the elevator.
Through the description, it is not difficult to discover that the internet of things interaction system provided by the embodiment can remind field personnel to start elevator test operation after completing network access operation, so that the network access behavior is switched to enter a functional test link.
Further, the internet of things interaction system further comprises: an elevator main control board;
theelevator terminal 602 is further configured to detect whether communication between theelevator terminal 602 and the elevator main control board is normal, where theelevator terminal 602 is connected to the elevator main control board through an internet of things communication interface;
theelevator terminal 602 is further configured to, if the communication is normal, obtain an elevator parameter transmitted by the elevator main control board, and send the elevator parameter to thecloud platform 601;
thecloud platform 601 is further configured to record the elevator parameters to perform network access operation.
It can be understood that, in the initial stage of developing the functionality test, different types of elevator key parameters, for example, elevator types, floor distributions, and the like, generally need to be manually entered in advance. Obviously, the inventor finds that at least the following problems exist in the link: the key parameters of the elevator are manually input, so that the efficiency is low, and the processing efficiency of subsequent test behaviors is seriously influenced.
For the situation, the behavior of automatically acquiring the elevator parameters is applied to replace the behavior of manually inputting the elevator key parameters, so that the efficiency of acquiring the behavior of the elevator key parameters is greatly improved, and the technical problem of low efficiency of the behavior of manually inputting the elevator key parameters is solved.
Specifically, the fifth embodiment of the present invention is carried on a type of elevator internet of things architecture, which can be seen in the elevator internet of things architecture shown in fig. 6.
At the machine room end, an elevator main control board and anelevator terminal 602 exist, and theelevator terminal 602 is connected with the elevator main control board through an internet of things communication interface. The Internet of Things (IoT) communication interface is a hardware interface, and thus both the elevator main control board and theelevator terminal 602 are deployed with the hardware interface.
Wherein the elevator master control board can be inserted into the elevator installation.
At the server, there is acloud platform 601, and thecloud platform 601 may be a server or a server cluster.
Specifically, in order to improve the efficiency of obtaining the behavior of the key parameters of the elevator, the parameters of the elevator can be collected by the elevator main control board through the elevator internet of things architecture, wherein the parameters of the elevator comprise parameters such as the type of the elevator, floor distribution information and the type of a fault template. If the communication between theelevator terminal 602 and the elevator main control board is normal, theelevator terminal 602 can obtain the elevator parameters. Then, thecloud platform 601 can obtain the elevator parameters wirelessly transmitted by theelevator terminal 602, and the key parameters of the elevator do not need to be manually entered.
Therefore, the behavior of automatically acquiring the elevator parameters replaces the behavior of manually inputting the elevator key parameters, the efficiency of acquiring the behavior of the elevator key parameters is greatly improved, and the technical problem of low efficiency of the behavior of manually inputting the elevator key parameters is solved.
Further, and more particularly with respect to conventional techniques for manually entering elevator key parameters, the manually entered elevator key parameters include, but are not limited to, elevator type, floor distribution information, and fault templates.
Through the above description, it is not difficult to find that the internet of things interaction system provided by the embodiment collects elevator parameters from the elevator main control board through the elevator internet of things framework which is formed by the elevator main control board, theelevator terminal 602 and thecloud platform 601. If the communication between theelevator terminal 602 and the elevator main control board is normal, theelevator terminal 602 can obtain the elevator parameters. Then, thecloud platform 601 can obtain the elevator parameters wirelessly transmitted by theelevator terminal 602, and obviously, the key parameters of the elevator do not need to be manually entered. Therefore, the behavior of automatically acquiring the elevator parameters replaces the behavior of manually inputting the elevator key parameters, the efficiency of acquiring the behavior of the elevator key parameters is greatly improved, and the technical problem of low efficiency of the behavior of manually inputting the elevator key parameters is solved.
Further, theelevator terminal 602 is further configured to generate communication abnormality information if communication is abnormal, and send the communication abnormality information to thecloud platform 601.
It can be understood that, if the communication between theelevator terminal 602 and the elevator main control board is abnormal, theelevator terminal 602 sends information that the communication of the main board is abnormal, that is, communication abnormal information, to thecloud platform 601.
The communication abnormal information includes a terminal Identifier (ID), a communication abnormal state, and the like. The terminal identification is identification information of theelevator terminal 602 to characterize the uniqueness of theelevator terminal 602.
Further, thecloud platform 601 is further configured to feed back an abnormality prompting message to theelevator terminal 602 when the communication abnormality message is received;
theelevator terminal 602 is further configured to perform an exception prompting action in a second preset prompting manner when receiving the exception prompting information.
Then, thecloud platform 601 may send an abnormality reminding message to theelevator terminal 602 to remind a field worker operating theelevator terminal 602 that the main board is in an abnormal communication state and that the communication condition between theelevator terminal 602 and the elevator main control board needs to be checked.
Wherein, can be equipped with the suggestion pilot lamp on theelevator terminal 602, the second presets the suggestion mode and can be the scintillation of suggestion pilot lamp.
Further, the elevator parameters comprise elevator types, floor distribution information and fault template types.
The elevator types include vertical passenger elevator, vertical goods elevator, and escalator, and the information can be obtained from the elevator main control board by theelevator terminal 602. Floor distribution information refers to floor distribution information of a vertical passenger or cargo lift, e.g., 1-N floors, -1-M floors, and whether floors stop information, where N and M represent positive integers, which is also obtained by theelevator terminal 602 from the elevator main control board. The failure template type refers to different failure template types set for different elevator types, and when an elevator fails, different failure template types can give different failure information.
Further, theelevator terminal 602 can obtain the operation data, the fault data and the like of the elevator besides the elevator parameters from the elevator main control board, and can transmit the operation data, the fault data and the like to thecloud platform 601 together.
Further, thecloud platform 601 can also provide services such as elevator management, elevator running state monitoring and elevator fault warning.
Further, more specifically, in terms of conventional technical means for manually entering elevator key parameters, the manually entered elevator key parameters include, but are not limited to, an internet of things identification, a terminal model number of theelevator terminal 602.
It can be understood that when theelevator terminal 602 sends the elevator parameters to thecloud platform 601, the information such as the internet of things identifier, the terminal model, the communication normal state and the like of theelevator terminal 602 can also be sent together. After receiving information such as elevator parameters, internet of things identifiers, terminal models and communication normal states, thecloud platform 601 can perform profiling on the network access test files through the information such as the elevator parameters, the internet of things identifiers, the terminal models and the communication normal states so as to obtain the network access test files corresponding to the current elevator and thecurrent elevator terminal 602.
Through the above description, it is not difficult to find that the internet of things interaction system provided by the embodiment can dispatch the actual operation behavior of field personnel through the abnormal prompt behavior when the communication between theelevator terminal 602 and the elevator main control board is abnormal.
Further, a more complete type of network entry instance and test instance may be provided, as shown in FIG. 7.
More specifically, when the network access behavior is started, theelevator terminal 602 may be connected to the elevator main control board to power on the system.
Then, theelevator terminal 602 may connect to thecloud platform 601 of the internet of things of the elevator through 4G or ethernet.
Then, after the connection between theelevator terminal 602 and thecloud platform 601 is established, a formal network access behavior is performed until network access information is obtained, and the procedure goes to the elevator test operation after the network access behavior is finished.
Further, the complete file of the elevator automatically appears in the subordinate customer account number of thecloud platform 601 of the internet of things of the elevator, and monitoring and fault warning tracking of the elevator are carried out.
In addition, the complete file of the elevator in the lower-level customer account number also passes through the information confirmation behaviors of the identity information of an elevator use unit, a manufacturing unit, a maintenance unit and the like.
