DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0018] Embodiment 1 Figure 1 FIG. 1 is a block diagram of a gas drainage parameter management system provided by an embodiment of the present invention. Figure 1 As shown, this embodiment provides a gas extraction parameter management system, which includes: at least one measuring instrument host, at least one location tag, at least one information collection device, at least one monitoring main station and at least one display.

[0019] Among them, the measuring instrument host, location tags, and displays are all deployed underground, and the monitoring main station is deployed on the ground; there are multiple boreholes underground, and each borehole is arranged with pipes. These pipes are connected to the extraction and discharge pipeline system on the ground to form a continuous channel. The gas in the borehole is extracted under the negative pressure generated by the pumping station, flows into the extraction and discharge pipeline system through the inserted pipe, and is then transported to the ground by the system; the pipeline between the borehole and the ground is used as the extraction pipeline.

[0020] In this embodiment, the number of measuring instrument hosts can correspond one-to-one to the number of boreholes in the well, or only a certain number of measuring instrument hosts can be deployed. When detection is required at a certain location, a measuring instrument host is deployed at that location. Therefore, the deployment location and number of the measuring instrument hosts can be flexibly selected according to actual needs; the measuring instrument host of this embodiment is used to detect the extraction parameters of the extraction pipeline in real time, and the extraction parameters include at least: methane concentration, negative pressure, temperature and humidity, carbon monoxide concentration, hydrogen sulfide concentration, carbon dioxide concentration, atmospheric pressure and operating mixed flow; each measuring instrument host stores the detected extraction parameters of the extraction pipeline locally.

[0021] Therefore, the measuring instrument host includes: a processor, a communication module, a concentration sensor, a pressure sensor, a temperature and humidity sensor, and a flow sensor; the communication module, concentration sensor, pressure sensor, temperature and humidity sensor, and flow sensor are all connected to the processor for communication; wherein, the processor can adopt an STM32 series single-chip microcomputer, or a PLC controller (programmable logic controller), etc., and the communication module can be a Bluetooth module, a WIFI module, etc.; wherein, the concentration sensor is used to detect the methane concentration, carbon monoxide concentration, hydrogen sulfide concentration, and carbon dioxide concentration in the extraction pipeline; the pressure sensor is used to detect the negative pressure and atmospheric pressure of the extraction pipeline; the temperature and humidity sensor is used to detect the temperature and humidity in the extraction pipeline; the flow sensor is used to detect the working condition mixed flow in the extraction pipeline.

[0022] In this embodiment, the number of location tags corresponds to the number of boreholes, and a location tag is deployed at each borehole. Each location tag is used to record the location information of each borehole. For example, the location tag can be an RFID (Radio Frequency Identification) tag. At each borehole, a location coordinate of the borehole is first constructed, and the location coordinate is written into an RFID tag. The RFID tag is installed at the borehole. By reading the location coordinate in the RFID tag at the borehole position, the location of the borehole can be known.

[0023] In this embodiment, the number of information collection devices can be flexibly selected according to actual needs. For example, the underground is divided into multiple areas, and there is an information collection device in each area. The information collection device is carried by the workers underground, and the workers use the information collection device to collect the location information recorded in all location tags in the area, as well as the extraction parameters detected by the measuring instrument host.

[0024] In this embodiment, the information collection device is an intrinsically safe mobile phone for use in mines, which is connected to the measuring instrument host and / or at least one location tag through wireless communication; an intrinsically safe mobile phone for use in mines refers to an intrinsically safe mobile phone designed for flammable and explosive environments such as coal mines. In coal mine operations such as gas extraction, the use of ordinary electronic equipment may generate sparks and cause explosions due to the presence of flammable gases. Therefore, the design and manufacture of intrinsically safe mobile phones for use in mines follow specific safety standards to ensure safety when used in hazardous environments such as coal mines.

[0025] Since the measuring instrument host underground cannot directly communicate with the monitoring main station on the ground, if the measuring instrument host underground is connected to the monitoring main station on the ground by cable, the cost of this method is relatively high; therefore, mining intrinsically safe mobile phones are used underground to collect the extraction parameters stored locally by each measuring instrument host and the location information in the location tag of each drill hole. After the workers leave the underground and reach the ground, the collected relevant data is automatically transmitted to the monitoring main station by the information acquisition equipment. This method has lower costs and is simpler and more convenient to collect data.

[0026] In this embodiment, the monitoring main station is used to establish a communication connection with the information acquisition device when the information acquisition device leaves the underground, so as to obtain the extraction parameters detected by the measuring instrument host and the location information of the borehole recorded by each location tag collected by the information acquisition device; the monitoring main station is used to perform statistical analysis on the extraction parameters detected by the measuring instrument host and the location information of the borehole recorded by each location tag to obtain a statistical data table of the extraction parameters; the monitoring main station of this embodiment has a large display screen, and the statistical data table of the extraction parameters can be displayed on the large screen.

[0027] The present invention deploys location tags underground, uses the location tags to record the location information of each borehole, and combines with the measuring instrument host to detect the extraction parameters of the extraction pipeline, so as to accurately locate the detection point; furthermore, it can reduce the time cost caused by the cumbersome operation process of the user, improve work efficiency, and realize the function of one person and one machine for fixed position positioning; and the present invention uses information collection equipment to collect the location information of each borehole underground and the corresponding extraction parameters. When the information collection equipment is brought to the ground outside the well, it can directly communicate with the monitoring main station deployed on the ground, and transmit the relevant data underground to the monitoring main station. The monitoring main station analyzes the relevant data, which can provide a favorable basis for the subsequent work arrangement adjustment; the data transmission method is simple and convenient, and has a low cost.

[0028] In this embodiment, the number of displays corresponds to the number of boreholes, and a display is deployed at each borehole. The display uses an LED display screen. The display also has a Bluetooth communication module, and a mine-used intrinsically safe mobile phone can communicate with the display; workers use the mine-used intrinsically safe mobile phone to synchronize the collected location information and extraction parameters of each borehole to the corresponding display, and the display is used to display the location information and extraction parameters of the borehole; the LED display screen of this embodiment can solve the problem of unclear recording after the user uses handwriting, and at the same time use the display screen to reduce personnel operation costs and error costs of irregular operations.

[0029] As a further optimization of this embodiment, the system further includes: a power supply module, the power supply module adopts a mining DC regulated power supply, and the power supply module is used to provide working power for the display.

The monitoring host can form corresponding historical statistical data and store daily, weekly and monthly reports for relevant personnel to check and print at any time.
