Problems solved by technology

However, in the process of drilling exploration, in order to better understand the situation in the drilling pool, sometimes it is necessary to go deep into the drilling pool for observation, and there are various gases in the drilling pool, including toxic and harmful gases. In order to ensure the personal safety of the monitoring personnel, We need to monitor the content of toxic and harmful gases in real time, so as to remind the monitoring personnel in time, but the existing monitoring can only be static monitoring, lack of special monitoring part, even if there is, it is easy to be interfered by signals, and the cost is high

Abstract

The invention discloses a wireless gas measurement and control system with early warning function. The wireless gas measurement and control system includes a controller. The controller is connected with a data acquisition unit, a GPRS terminal and a wireless communication module at the same time, wherein the data acquisition unit comprises an FPGA main controller, an A/D converter, an eight-channel analog switch and a signal conditioning circuit; the A/D module converter and the eight-channel analog switch are connected with the FPGA main controller at the same time; the eight-channel analog switch is further connected with the signal conditioning circuit and the A/D converter. The signal conditioning circuit is connected with a hydrogen sulfide sensor and a sulfur dioxide sensor. The controller is further connected with an alarm module used for alarming when a collected data triggers an alarm threshold value. Based on the above principle, the wireless gas measurement and control system with early warning function, can collect a data triggering alarm threshold value for reminding the alarm, and transmit alarm information through the wireless transmission, accordingly the wiring difficulty is reduced, signal interference in the transmission process is also reduced, to help customers reduce the cost of the project.

Description

technical field [0001] The invention relates to the field of gas measurement and control, in particular to a wireless gas measurement and control system with an early warning function. Background technique [0002] Gas drilling has been widely used because it can effectively protect low-pressure oil and gas reservoirs, solve vicious lost circulation, differential pressure sticking, and increase ROP. However, in the process of drilling exploration, in order to better understand the situation in the drilling pool, sometimes it is necessary to go deep into the drilling pool for observation, and there are various gases in the drilling pool, including toxic and harmful gases. In order to ensure the personal safety of the monitoring personnel, We need to monitor the content of toxic and harmful gases in real time, so as to remind the monitoring personnel in time, but the existing monitoring can only be static monitoring, lack of special monitoring part, even if there is, it is eas...
