[0067] The pressure plates 220 of the two clamp assemblies are respectively pressed against the end faces of the upper shell 110 and the lower shell 120, so that the connecting nut 320 is pressed against the clamp connecting plate 250, so that the two clamp assemblies 200 are tightened through the connecting screw 310, that is, the upper shell and the lower shell are tightened with each other through the clamp assembly 200, so that the upper shell and the lower shell are clamped and fixed as a whole.

[0071] The air pump 430 is driven by a motor, and the motor is controlled and driven by an air pump drive board 431. The air pump drive board 431 is used to control the running state of the motor, such as start and stop, power, etc., and the existing motor driver or its similar functional part can be directly used as the air pump drive board 431; the control end of the air pump drive board 431 is communicatively connected with the first signal end (pin) of the controller, so that the controller can send a control instruction to the air pump drive board 431 to control the running state of the air pump. In this embodiment, the motor is powered by the air pump drive board 431, and the air pump drive board 431 controls the running state of the air pump by adjusting the power supply to the motor, controlling the current on and off, etc. This is the prior art, and the related technologies of the existing motor driver driving and controlling the motor can be directly referenced or adopted.

[0072] The power connection end of the air pump driving board 431 is conductively connected to the connection end of the terminal block 480, and the connection end of the terminal block 480 is conductively connected to the external power source through a wire, so as to guide the current of the external power source to the connection end of the terminal block 480. The external power source of this embodiment can be a battery of the drone.

[0073] The signal end of the nitrogen dioxide sensor 440 is communicatively connected to the signal access end of the nitrogen dioxide sensor control board 441.

[0074] The signal end of the sulfur dioxide sensor 450 is communicatively connected to the signal access end of the sulfur dioxide sensor control board 451. The sulfur dioxide sensor control board 451 is used to collect the electrical signal obtained by the sulfur dioxide sensor 450 and convert it into a digital signal after amplification, filtering and other processing; the signal output end of the sulfur dioxide sensor 450 is communicatively connected to the third signal end of the controller, so that the signal collected by the sulfur dioxide sensor 450 can be transmitted to the controller and processed by the controller; the power connection end of the sulfur dioxide sensor 450 and the sulfur dioxide sensor control board 451 are conductively connected to the output end of the terminal block 480.

[0075] The nitrogen dioxide sensor control board 441 and the sulfur dioxide sensor control board 451 can be understood as the circuit part of the existing corresponding sensor with digital signal output is separately set on the nitrogen dioxide sensor control board 441 and the sulfur dioxide sensor control board 451, while the sulfur dioxide sensor 450 and the nitrogen dioxide sensor 440 are only their signal detection ends (probe parts). For example, the US SPEC Sensors SO2 sulfur dioxide sensor - 3SP-SO2-20 adopts this design method of separating the control board from the detection end.

[0076] The controller may be an MCU, a CPU, a single-chip microcomputer, a PLC, etc. In this embodiment, the signal terminal of the controller needs to be determined according to the actual situation, and the first signal terminal, the second signal terminal, etc. are only used to illustrate different signal terminals and have no other meanings. In this embodiment, the controller is used to send and receive, analyze control instructions, and perform corresponding parameter calculations.

[0077] The controller and the wireless module are arranged on the main control board 470. The wireless module is used for wireless communication with external devices and may be a 4G module, a WIFI module, a GPRS module, etc. The main control board 470 is also provided with:

[0078] GPS module, used for positioning via GPS;

[0079] Memory, used to temporarily store data needed by the controller;

First, turn on the air pump 430, the air pump pumps external air to the nitrogen dioxide sensor 440 and the sulfur dioxide sensor 450, and finally discharges it through the exhaust pipe. The data detected by the nitrogen dioxide sensor 440 and the sulfur dioxide sensor 450 are processed by the nitrogen dioxide sensor control board 441 and the sulfur dioxide sensor control board 451 and then transmitted to the controller. The controller compares the threshold value set by the built-in program. Once the threshold value is exceeded, the controller sends a warning message and the monitored parameters, the GPS position corresponding to the parameters, etc. to the external device (server) through the wireless module. Example

[0083] See also Figure 6-Figure 16 The difference between this embodiment and the first embodiment is that a mounting mechanism is added, and the connecting device of this embodiment is a hook assembly 500, and the hook assembly 500 includes an upper connecting rod 311 and a lower connecting rod 312. One end of the upper connecting rod 311 is assembled and fixed to a clamp connecting plate 250 of a clamp assembly, and the other end is assembled and fixed to the first connecting block 510;

[0084] The lower connecting rod 312 is assembled and fixed to the clamp connecting plate 250 of another clamp assembly, and the other end is assembled and fixed to the second connecting block 520;

[0085] The upper connecting rod 311 passes through the first connecting block 510, and the second connecting block 520 is provided with a blind groove 522 plugged with the end of the upper connecting rod 311. The first connecting block 510 is also provided with a hook 511, and a hook groove 512 is formed between the hook 511 and the first connecting block 510.

[0086] The second connecting block 520 is fixed with a hook hinge plate 521, the hook hinge plate 521 is hinged to one end of a hook connecting plate 531 through a first pin shaft 551, and the other end of the hook connecting plate 531 is connected and fixed to a hook handle 530;

[0087] The hook hinge plate 521 is also hinged to the hinge block 542 through the second pin shaft 552. The hinge block 542 is fixed to one end of the pull buckle 540. A hook strip 541 is fixed to the other end of the pull buckle 540. The hook strip 541 is inserted into the hook groove 512 and the hook handle 530 is rotated toward the lower shell body 120 to tighten the first connecting block 510 toward the second connecting block 520 through the hook strip 541, thereby realizing the connection, fixation and clamping of the two clamp assemblies.

[0088] Preferably, see Fig.12 In order to prevent the buckle 540 and the buckle groove 512 from loosening due to the buckle handle 530 rotating toward the upper shell, that is, the two clamp components loosening, thereby causing the upper shell and the lower shell to loosen, which poses a great safety hazard and is not conducive to use. Therefore, the applicant designed a stop block 563, which is a triangular body, one side of which is a driving inclined surface 5631, which is arranged outward and at an angle with the buckle hinge plate 521;

[0089] The hook hinge plate 521 is provided with a clearance groove 5211 and a guide through hole 5212 into which the stop bevel block 563 can be completely installed. One end of the guide through hole 5212 is connected to the clearance groove 5211, and the other end passes through the hook hinge plate 521.

[0090] The stop bevel block 563 is assembled and fixed with one end of the guide rod 562, and the other end of the guide rod 562 is fitted with a spring 564, passes through the guide through hole 5212, and finally assembled and fixed with the pull button 561; in the initial state, the stop bevel block 563 extends out of the clearance groove 5211 under the action of the spring. When the hook connecting plate 531 rotates toward the stop bevel block 563 until it contacts the driving inclined surface 5631, the hook connecting plate 531 drives the stop bevel block 563 through the driving inclined surface 5631 to overcome the spring elastic force and enter the clearance groove until the hook connecting plate 531 passes through the stop bevel block 563. At this time, the end face of the stop bevel block 563 fits with the end face of the hook connecting plate 531, thereby preventing the hook connecting plate 531 from passing through the stop bevel block 563, and thus preventing the two clamp assemblies from loosening.

[0091] See also Figure 6-Figure 7 , Figure 13-Figure 16 The mounting mechanism includes a mounting plate 130, and at least two slot plates 640 and a limit block are arranged on the end surface of the mounting plate 130 close to the upper shell 110, and a slide groove 641 is provided between the two slot plates 640;

When the clamping screw 340 rotates circumferentially, the second clamp block 620 moves synchronously with the clamping screw 340 in the axial direction of the clamping screw 340 to move closer to or farther from the clamping screw 340.

[0093] Limiting nuts 341 are fixed at both ends of the clamping screw 340 , respectively. The limiting nuts 341 are used to limit the maximum displacement of the first clamping block 610 .

[0097] The mounting plate 130 is assembled and fixed to the clamp connection hole 251 that is not assembled with the connecting screw 310 (or the upper connecting rod 311) through the mounting screw 330, thereby achieving the mounting and assembly of the entire pod and the drone.

[0101] See also Fig.17 This embodiment is a monitoring method for the pod in Embodiment 1 and Embodiment 2, and includes the following steps:

[0102] S1. The monitoring system in the pod is powered on and each device is initialized;

[0103] S2. The wireless module (GPRS module) establishes a network connection with the ground server or control host;

[0104] S3, the software built into the controller is verified through key pairing with the ground server or control host to obtain the right to send and receive commands or the right to interact with data;

[0105] S4, the controller receives the control command from the ground server or the control host, and then controls the air pump, the nitrogen dioxide sensor, and the sulfur dioxide sensor to start working;

[0106] S5, nitrogen dioxide sensor and sulfur dioxide sensor collect nitrogen dioxide and sulfur dioxide data in the air flow sent by the air pump;

[0107] S6, the nitrogen dioxide sensor and the sulfur dioxide sensor transmit the collected data to the nitrogen dioxide sensor control board and the sulfur dioxide sensor control board. The data is processed by the nitrogen dioxide sensor control board and the sulfur dioxide sensor control board and then transferred to the controller. After being processed by the controller, the data is transmitted back to the ground server or control host through the wireless module.

[0108] Preferably, the data obtained by the nitrogen dioxide sensor and the sulfur dioxide sensor in the initial stage are uniformly processed and transmitted in ppb units, and the subsequent receiving unit can convert the ppb concentration data into mg / mm3 concentration data according to the following conversion coefficient table:

[0109] Gas Type SO2 NOX Conversion factor 2.857 2.054

[0110] Conversion factor, for example, if the current SO2 concentration is 100 ppb, then the conversion to ug / mm3 is 100*2.86=286 ug / mm3.

[0111] See also Fig.18 In S3, the pairing verification process is as follows: first, the device number of the monitoring pod (in this embodiment, it is proposed to be: the SIM card number installed in the pod) is entered in the pairing verification interface through the ground equipment (ground server or control host), and then the corresponding verification information (in this embodiment, it is proposed to be: AXKJ) is sent to the number. After receiving and verifying the pairing information, the pod sends the information collected by the sulfur dioxide sensor and nitrogen dioxide sensor installed in the system back to the controller, and enters the data collection and sending ready stage.

[0112] See also Fig.19 After the ground equipment and the pod are paired and verified, the ground equipment can perform corresponding operations on the pod via GSM text messages, including:

[0113] 1) Start and stop of gas monitoring;

[0114] 2) Setting the address of the monitoring data receiving server (optional); the pod needs to perform corresponding operations according to the instructions of the control end.

[0115] The initial method to be adopted for starting and stopping some functions of gas monitoring is as follows: First, after the exhaust gas monitoring pod is started, the initialization of each module is completed, including one minute of preheating of the gas sensor module (nitrogen dioxide sensor, sulfur dioxide sensor, nitrogen dioxide sensor control board, sulfur dioxide sensor control board), and then searching for the GPRS network and connecting; after that, wait for the ground equipment to send an instruction to start collection (planned to be "START"). After receiving the instruction, the pod starts collecting data and sends the data to the ground equipment. At the same time, it determines whether the collected concentration data exceeds the combustion test calibration value. If the concentration information exceeds the standard, a notification SMS is sent to the ground equipment.

[0116] This embodiment uses the STM32 embedded platform to transmit monitoring data. Based on the output data of the sensor module, the gas concentration data is sent to the ground equipment via TCP / IP according to the interface protocol of the SIM800 module. In terms of the monitoring data transmission cycle, the monitoring pod of the drone platform is planned to be once every 5 seconds, and the fixed monitoring point equipment is planned to be once every 1 minute.

[0117] The length of the data sent at a time is 10 bytes, and the data format to be used is as follows:

[0118] 1 2 3 4 5 6 7 8 9 10 Start bit Device Number SmallDatetime SmallDatetime SmallDatetime SmallDatetime High SO2 concentration Low SO2 concentration Low NOx concentration Low NOx concentration 0xFF 0x81 0x11 0x10 0x23 0x1A 0x00 0x20 0x00 0x30

[0119] Among them, the first byte is the start bit, which is planned to be 0xFF, the second byte is the device number used to determine the information of the data sending device, and the 3rd to 6th bytes are the time bits Small Datetime, which are the collection time of the collected data. The first 2 bytes of this part of information store the number of days after the base date (January 1, 1900). The last 2 bytes store the number of minutes after midnight. The 7th to 10th bytes are the concentration values ​​of the collected gas, in ppb.
