[0028] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention.

[0029] Example 1

[0030] The present invention provides a micro gas monitoring device that is compatible with both a pump suction mode and a diffusion mode, comprising a housing 1, a first mounting plate 101, a second mounting plate 102, a housing diffusion hole 103, a power supply unit 2, a circuit board 3, a communication module 7, an audible and visual alarm 8, and an antenna 9. The housing 1 is provided with a first mounting plate 101 and a second mounting plate 102. The top of the housing 1 is provided with an antenna 9. The right side of the housing 1 is provided with an audible and visual alarm 8. The bottom of the housing 1 is provided with a plurality of housing diffusion holes 103, the number of which depends on the specific situation. The first mounting plate 101 is provided with a circuit board 3, which provides the power required for the sensor to operate and transmits the data collected by the sensor. The circuit board 3 is electrically connected to the communication module 7 and remotely transmits the monitoring data to the relevant monitoring platform via the antenna 9. The second mounting plate 102 is provided with a power supply unit 2, which supplies power to the entire system. The audible and visual alarm 8 is electrically connected to the circuit board 3.

[0031] like Figure 1-3 As shown, the pumping mode is selected. Specifically, it includes a sampling head 4, a pumping sensor module 5, a sampling air pump 6, a float flowmeter 11, a high-efficiency filter 12, an air outlet connector 13, and a pumping module mounting plate 14. The pumping module mounting plate 14 is mounted on the bottom of the housing 1 and is used to mount the pumping sensor module 5. The pumping sensor module 5 is a closed module containing a gas sensor. The outer shell is a pumping closed shell 501 and is equipped with two pumping air nozzles 502. The pumping sensor module 5 is electrically connected to the circuit board 3.

[0032] The number of pump-suction sensor modules 5 can be determined based on actual needs. Multiple pump-suction sensor modules 5 are connected in series via gas pipes 15. In this embodiment, eight pump-suction sensor modules are installed as an example. Gas sensor types include, but are not limited to, VOCs sensors, combustible gas sensors, hydrogen sensors, oxygen sensors, and methanol sensors for detecting flammable and explosive gases, as well as hydrogen sulfide sensors, ammonia sensors, sulfur dioxide sensors, carbon monoxide sensors, nitrogen oxide sensors, chlorine sensors, hydrogen chloride sensors, and hydrogen fluoride sensors for detecting toxic and hazardous gases.

[0033] In this embodiment, a sampling head 4 is mounted on the top of the housing 1, and an air outlet connector 13 is mounted on the bottom. A sampling air pump 6 and a float flowmeter 11 are also mounted on the second mounting plate 102. The sampling air pump 6 is electrically connected to the circuit board 3, and its operation is controlled by the circuit board 3.

[0034] Working Principle: When monitoring is being carried out, the sampling air pump 6 begins pumping air. The gas to be tested enters the device from the sampling head 4 along the pipeline. After being filtered out of dust, debris, and moisture by the high-efficiency filter 12, it is then sent by the sampling air pump 6 to the pump-suction sensor module 5. The gas to be tested is detected in real time and data processing is performed in the pump-suction sensor module 5. The circuit board 3 transmits the detection data in real time and sends it remotely to the relevant monitoring platform through the communication module 7 and antenna 9. The pump-suction sensor module 5 is then connected to the float flowmeter 11, which monitors the gas flow in the pipeline in real time. The float flowmeter 11 is connected to the air outlet connector 13 at the bottom of the box 1 to discharge the gas.

[0035] Example 2

[0036] This embodiment 2 is completed on the basis of embodiment 1, and the diffusion working mode is selected. Figure 4-6 Specifically, the housing 1 includes a diffusion sensor module 16, a diffusion housing 1601, housing diffusion holes 1602, a diffusion module mounting plate 17, and threaded holes 1701. The diffusion module mounting plate 17 is mounted on the bottom of the housing 1. The diffusion module mounting plate 17 is provided with several threaded holes 1701 for mounting the diffusion sensor module 16. The diffusion sensor module 16 is an open-gas module containing a gas sensor and a signal analysis and processing circuit board. The housing 1601 is threaded, with housing diffusion holes 1602 defined at the top. The diffusion sensor module 16 is electrically connected to the circuit board 3. The threaded holes 1701, housing diffusion holes 1602, and housing diffusion holes 103 must be mounted concentrically. The mounting hole at the top of the housing 1 is sealed with a waterproof plug 10 to prevent water from entering the housing.

[0037] The number of diffusion sensor modules 16 can be determined based on actual needs. Six sensors are installed in this embodiment. Gas sensor types include, but are not limited to, VOCs sensors, combustible gas sensors, hydrogen sensors, oxygen sensors, and methanol sensors for detecting flammable and explosive gases, as well as hydrogen sulfide sensors, ammonia sensors, sulfur dioxide sensors, carbon monoxide sensors, nitrogen oxide sensors, chlorine sensors, hydrogen chloride sensors, and hydrogen fluoride sensors for detecting toxic and hazardous gases.

[0038] Working principle: When the monitoring work is carried out, the gas sensor contained in the diffusion sensor module 16 contacts the gas to be measured through the diffusion hole 1602 of the shell and the diffusion hole 103 of the box, realizing real-time detection and analyzing and processing data. The circuit board 3 transmits the detection data in real time and sends it remotely to the relevant monitoring platform through the communication module 7 and the antenna 9.
