Referring to fig. 18, in S3, the procedure of pairing verification is as follows: firstly, inputting an equipment number (planned to be: SIM card number installed in the nacelle) of the monitoring nacelle in a pairing verification interface through ground equipment (a ground server or a control host), then sending corresponding verification information (planned to be: AXKJ in the embodiment) to the number, sending information collected by a sulfur dioxide sensor and a nitrogen dioxide sensor assembled in the system back to a controller after the nacelle receives and verifies the pairing information, and entering a data collection and sending ready stage.
Referring to fig. 19, after the ground device and the pod are paired and verified, the ground device can perform corresponding operations on the pod in a GSM short message manner, which includes:
1) start and stop of gas monitoring;
2) monitoring the setting (optional) of the address of the data receiving server; the nacelle needs to perform corresponding operations according to the instructions of the control end.
The starting and stopping part of the gas monitoring function is preliminarily adopted in the following modes: firstly, after the tail gas monitoring pod is started, initializing each module, preheating a gas sensing module (a nitrogen dioxide sensor, a sulfur dioxide sensor, a nitrogen dioxide sensor control panel and a sulfur dioxide sensor control panel) for one minute, and then searching and connecting a GPRS network; and then, waiting for the ground equipment to send an instruction (planned to be 'START') for starting acquisition, starting to acquire data and sending the data to the ground equipment after the pod receives the instruction, meanwhile, judging whether the acquired concentration data exceeds a combustion test calibration value, and if the concentration information exceeds the standard value, sending a notification short message to the ground equipment.
In this embodiment, an STM32 embedded platform is used to transmit monitoring data, and gas concentration data is sent to the ground device in a TCP/IP manner according to an interface protocol of the SIM800 module on the basis of acquiring data output by the sensor module. In the aspect of a monitoring data sending period, the unmanned aerial vehicle platform monitoring pod is planned to be once in 5 seconds, and the fixed monitoring point equipment is once in 1 minute.
The data length of single transmission is 10 bytes during transmission, and the data format to be adopted is as follows:
the 1 st byte is the start bit and is supposed to be 0xFF, the 2 nd byte is the information used for determining the data sending device, the 3 rd to 6 th byte time bit Small Datetime is the collection time of the collected data, and the first 2 bytes of the part of information store the days after the base date (1/1900). The last 2 bytes store minutes after midnight 0. Bytes 7-10 are the concentration values of the collected gas in ppb.
