Each conveying device 2 is connected with the liquid supplement bottle 1 and a gas concentration detection sensor 3 respectively. The surface of each gas concentration detection sensor 3 is provided with an NFC tag. The controller is connected with the conveying devices 2 and the NFC tags respectively. The controller is used to control the conveying devices 2 to convey reagents to the gas concentration detection sensors 3 and write the liquid supplement information of each gas concentration detection sensor 3 into the NFC tag. The NFC reader / writer is connected with the NFC tag. The NFC reader / writer is used to read the liquid supplement information in each NFC tag.

[0024] A plurality of gas concentration detection sensors 3 are arranged at different positions in the roadway, and the number of conveying devices 2 matches the number of gas concentration detection sensors 3. Each gas concentration detection sensor 3 is connected to one conveying device 2. The type of conveying device 2 is not limited in the embodiment. The conveying device 2 can be an electric piston, a peristaltic pump, or a metering pump, etc. The liquid supplement bottle 1 is used to store chemical reagents, so that the conveying device 2 can convey the chemical reagents in the liquid supplement bottle 1 to the corresponding gas concentration detection sensor 3.

[0025] The NFC tag and the NFC reader are a new technology, i.e. Near Field Communication (NFC). The controller can write data into the NFC tag. When the NFC reader is close to the NFC tag, the radio frequency field of the NFC reader can activate the NFC tag to establish a communication connection. The NFC reader can detect the existence of the NFC tag and read data from the tag. The above method of writing liquid supplement information into the NFC tag by the controller and reading the liquid supplement information in each NFC tag by the NFC reader is prior art, which will not be described here. The controller can record the frequency and time of each conveying device 2 conveying chemical reagents to the corresponding gas concentration detection sensor 3. When the user inspects the roadway, the user can obtain the liquid supplement information in each NFC tag by using the NFC reader, and can maintain the gas concentration detection sensor 3 according to the liquid supplement information.

[0026] The automatic liquid supplement system for the gas concentration detection sensor provided in the embodiment comprises a liquid supplement bottle, a plurality of conveying devices, an NFC tag, an NFC reader, and a controller. Each conveying device is connected to the liquid supplement bottle and the gas concentration detection sensor. The surface of each gas concentration detection sensor is provided with an NFC tag. The controller is connected to the conveying device and the NFC tag. The controller is used to control the conveying device to convey reagents to the gas concentration detection sensor, and to write the liquid supplement information of each gas concentration detection sensor into the NFC tag. The NFC reader is connected to the NFC tag. The NFC reader is used to read the liquid supplement information in each NFC tag. The automatic liquid supplement system for the gas concentration detection sensor provided in the embodiment can save labor cost by using the conveying device and the liquid supplement bottle to realize the automatic liquid supplement of the gas concentration detection sensor. The staff can easily understand the liquid supplement information of each gas concentration detection sensor by using the NFC tag and the NFC reader, so as to facilitate the later maintenance and traceability.

[0027] Based on the above embodiment, the conveying device 2 is an electric piston. A plurality of electric pistons are connected to the controller through a switch matrix. The input port of the electric piston is connected to the liquid supplement bottle 1. The output port of the electric piston is connected to the gas concentration detection sensor 3.

[0028] The switch matrix in the embodiments of the present application is an electronic switch network that can dynamically distribute multiple input signals to multiple output channels, and in the control of the electric piston, it allows the controller to selectively activate any one electric piston as needed.

[0029] Further, the electric piston comprises an electromagnetic coil, a core, a piston, a cylinder, an end cover, a guide sleeve and a spring, the core is arranged in the electromagnetic coil, the end cover is connected to the two ends of the cylinder respectively, the electromagnetic coil and the core are installed at one end of the cylinder, the guide sleeve is arranged in the interior of the cylinder, the piston is in sliding connection with the guide sleeve, and the spring is connected to the other end of the piston and the cylinder respectively.

[0030] The electromagnetic coil is the main component of the electric piston, which generates a magnetic field when an electric current passes through it; the core is usually made of magnetic material such as iron or steel, which is placed inside the coil to enhance the magnetic field; the piston is the moving part of the electric piston, which corresponds to the core, when the core is magnetized, the piston will be attracted or repelled; the cylinder is the fixed part of the electric piston, usually made of metal or plastic, used to fix the electromagnetic coil and the core; the end cover is used to close the two ends of the cylinder, to protect the internal components and provide a mounting surface; the guide sleeve is used to guide the linear motion of the piston, reducing friction and wear. The spring can be used to pull the piston back to the initial position when the power is off. An input port connected to the liquid supplement bottle 1 and an output port connected to the gas concentration detection sensor 3 can be opened on the cylinder. When the piston moves outward, the pressure in the liquid supplement bottle 1 decreases, and the liquid is sucked into the cylinder of the electric piston; when the piston moves in the opposite direction, it pushes the liquid in the cylinder, and the liquid is pushed out of the electric piston through the output port.

[0031] Based on the above embodiment, a sealing element is connected between the piston and the cylinder in the embodiments of the present application. The side wall of the cylinder is provided with a position sensor connected to the controller, and the position sensor is used to detect the position of the piston.

[0032] The sealing element in the embodiments of the present application is used to prevent liquid leakage, which is usually made of rubber or other elastic materials.

[0034] Based on the above embodiment, the surface of the liquid supplement bottle 1 and / or the conveying device 2 is provided with a heat preservation layer and a waterproof layer. Since the environment in the mine is relatively harsh, the heat preservation layer and the waterproof layer arranged on the surface of the liquid supplement bottle 1 and the conveying device 2 can avoid affecting the activity of the chemical reagent and causing failure of the conveying device 2.

[0035] Based on the above embodiment, the embodiment of the present application further comprises a syringe, the syringe is detachably connected with the liquid supplement pipe of the gas concentration detection sensor 3 through a luer joint, and a valve is arranged on the liquid supplement pipe between the syringe and the gas concentration detection sensor 3.

[0036] Based on the above embodiment, the embodiment of the present application is provided with a camera connected with the controller at the liquid supplement bottle 1, and the camera is used to detect the liquid level in the liquid supplement bottle 1. By arranging the camera, the user can conveniently know the remaining amount of the chemical reagent in the liquid supplement bottle 1, so as to supplement in time.

[0037] The automatic liquid supplement system of the gas concentration detection sensor provided by the present application is described in detail above. The embodiments in the specification are described in a progressive manner, and each embodiment mainly describes the difference from other embodiments. The same and similar parts of each embodiment can be referred to each other. It should be pointed out that, for ordinary skilled in the art, without departing from the principle of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
