Application of methane sensor in coal mine
From the perspective of my country's various development plans and policies, there is no doubt that new energy will become the main force of power generation in the future, but now China's power structure is still dominated by thermal power. According to data from the China Electricity Council, the national full-caliber power generation in 2020 will be 7.62 trillion kilowatt-hours. Among them, thermal power generation is 5.17 trillion kilowatt-hours, accounting for nearly 70%, far exceeding other forms of energy generation. The main source of thermal power generation is coal. Coal is my country's main energy source and plays an irreplaceable role in the development of the national economy. In the process of coal mining, coal mine gas explosion accidents frequently occur, causing huge losses to people's lives and economic properties. Methane is the main component that causes gas explosions. At present, the domestic sensor technology used to detect methane concentration is relatively backward. The measurement stability is poor, the detection range is narrow, and it is easily affected by other gases. At the same time, the workload of system maintenance is relatively large. As a result, the reliability and credibility of detection data for methane and other explosive gases is reduced. Therefore, how to quickly and stably detect and early-warning the concentration of methane gas in coal mines is of great significance for preventing coal mine gas leakage accidents. The choice of methane sensor The methane sensor is used for the detection of methane concentration in the air. When the concentration exceeds the preset alarm value, it will send out an audible and visual alarm signal to remind users to take safety measures in time to prevent explosion and poisoning Accidents occur, thereby guaranteeing the safety of life and property. The methane sensor uses an electrochemical sensor, which has the characteristics of rapid and sensitive response and strong anti-interference ability. After a unique compensation algorithm and multi-stage standard gas calibration, it also has the characteristics of long life, high precision, high repeatability and high stability. This methane sensor has a large LCD display, and the shell is sturdy and has a high protection level, and the protection level can reach IP65, which can be applied to most harsh on-site environments. The equipment adopts wide-voltage 10-30V DC power supply, 485 signal output, standard Modbus-RTU communication protocol, ModBus address can be set, baud rate can be changed, and the communication distance is up to 2000 meters. Methane gas detection and alarm system function: (1) Real-time monitoring of the content of methane gas and toxic gas near the coal mine environment, and real-time alarm when a certain concentration is reached. (2) Real-time watch on-site conditions through the host computer system monitoring center. (3) The above monitoring data is recorded in the monitoring center in real time, and the data is unified and centralized management. (4), the user first turns on the alarm function on the platform. When the data exceeds the limit, it can send out the alarm information on the spot through various methods such as sound and light alarm, LED screen display, etc., and then The platform will send a text message alert or email alert to the designated contact, and the font color of the value on the platform will also change to red, and the manager will be notified as soon as possible to take measures as soon as possible to avoid losses. (5) The platform provides historical query of various data, historical track query, historical registration query, and also has the function of data storage. Historical data can be stored on the cloud platform for two years. (6) The management software provides event query, alarm configuration and query, and environment parameter browsing. Users can log in to the cloud platform anytime and anywhere to view the status of the device, view real-time monitoring data, download and print data, etc. Methane gas detection is very important in coal mine production. It is directly related to the safety and stability of the entire coal mine underground. The use of methane sensors is beneficial to improve the stability and stability of the methane monitoring system. Reliability. Although there are still many problems in the methane control and restriction technology in coal mines in our country, there are still many loopholes in the coal mine monitoring system that need to be filled, but with the continuous development of my country's coal mine industry, it is believed that in the future our country's coal mine monitoring The technology will be developed by leaps and bounds to further improve the safety, reliability and stability of coal mine production in our country, and to reduce the hazards caused by methane explosions.
For business owners unsure of how to effectively incorporate new technology into our sensor solution, life may have just become a little easier.
With all the pros and cons of different in mind, click Rika Sensors to learn more about and decide which sensor solution option is best for your case.
Basically, you cannot have a environmental monitoring systems without having the right sensor solution. Since you are going to use it regularly, be sure to invest in one that has a high quality.
