This interface can communicate with external sensors of RS485 and realize the control of controllable power supply to realize the control of power consumption of external sensors.

[0097] The following is a detailed introduction to the specific steps of the wireless remote transparent transmission debugging method based on the above circuit. The specific process is as follows: Figure 8 As shown:

[0098] S1. Build a communication link, set the message network priority rules, and initialize the message network connection status;

[0099] S2, the telemetry terminal reads the message network status and selects the lowest priority message network based on the result;

[0100] S3: Perform long-distance data transparent transmission. If the low-priority message network reports an error, switch to the next-level message network for secondary long-distance data transparent transmission;

[0101] S4, verify the transmission data, and determine the abnormality of the message network based on the transmission data;

[0102] S5. Carry out emergency processing according to abnormalities in the message network;

[0103] The following is a detailed description of the method steps:

[0104] S1. Build a communication link, set the message network priority rules, and initialize the message network connection status;

[0105] The message network priority rule is: when the wired network, wireless network, and Beidou short message network are all connected, they are used in the order of wired network, wireless network, and Beidou short message network, where the wired network is defined as the third priority, the wireless network is the second priority, and the Beidou short message network is the first priority.

[0106] S2, the telemetry terminal reads the message network status and selects the lowest priority message network based on the result;

[0107] The network scenario for selecting the lowest priority message is as follows:

[0108] Scenario 1: When the wired network, wireless network, and Beidou short message network are all in abnormal status, the system temporarily stores data;

[0109] Scenario 2: When the wired network is connected and the wireless network and Beidou short message network are in an irregular state, the wired network with the third priority is selected;

[0110] Scenario 3: The wired network is in an abnormal state, the wireless network is in a connected state, and the Beidou short message network state is irregular, then the second priority wireless network is selected;

[0111] Scenario 4: When both the wired network and the wireless network are in abnormal status and the Beidou short message network is in connected status, the Beidou short message network is selected;

[0112] Scenario 5: During data transmission, the low-priority network recovers from an abnormal state; the data transmission network calls back the low-priority network;

[0113] S3: Perform long-distance data transparent transmission. If the low-priority message network reports an error, switch to the next-level message network for secondary long-distance data transparent transmission;

[0114] The specific process of long-distance data transmission is as follows: Fig. 9 As shown, the specific method is as follows:

[0115] S31, the telemetry terminal is connected to the transparent transmission server, and the sensor is turned on;

[0116] S32, the telemetry terminal detects whether a valid instruction from the transparent transmission server is received. If the instruction is valid, the data to be transmitted is written into the queue and waits for processing;

[0117] The data processing flow to be transmitted is as follows: Fig.10 As shown, the details are as follows:

[0118] S321, the system checks whether the current time has reached the preset sensor data collection cycle;

[0119] S322, if the collection time has been reached, the collected data is written into the queue;

[0120] S323, the system checks whether the data items in the queue have been processed;

[0121] S324, confirming that the data has been correctly extracted and is ready, the system will perform further data processing and analysis.

[0122] In the above steps, the system first stores the data collected by the sensor in a queue without processing it immediately, which helps to manage and buffer the data, ensure the stability and efficiency of data processing, and perform a secondary check on the data written to the queue to ensure that each data packet is processed, effectively improving the accuracy of system detection.

[0123] S33, the telemetry terminal detects whether the transparent transmission data has been processed;

[0124] S34, after the transparent transmission data processing is completed, the telemetry terminal transmits the data to the transparent transmission server;

[0125] S4, verify the transmission data, and determine the abnormality of the message network based on the transmission data;

[0126] The judgment of the abnormal situation of the message network is specifically as follows:

[0127] S41, the transparent transmission server receives the sensor monitoring data transmitted by the telemetry terminal and performs data analysis;

[0128] S42. When data analysis reports an error, the transparent transmission server reports the abnormality of the telemetry terminal sensor and issues an abnormality alarm;

[0129] S43. When the data is parsed successfully and the number of abnormal network status of the message is greater than or equal to 2, the transparent transmission server reports the location of the telemetry terminal and the network abnormality, and issues an abnormal alarm;

[0130] S44. When the data is parsed successfully and the Beidou short message network status is abnormal, the transparent transmission server will register the risk status of the telemetry terminal.

[0131] S5. Carry out emergency processing according to abnormalities in the message network;

[0132] In summary, the present invention ensures the real-time connection status between the telemetry terminal and the server by arranging multiple message networks in a hierarchical manner, and can respond to server instructions immediately.
