Natural gas well safety monitoring system

Abstract

The invention discloses a natural gas well safety monitoring system which comprises multiple gas delivery pipeline pressure measurement and control terminals and a security monitoring and control server in remote wireless connection with the gas delivery pipeline pressure measurement and control terminals through a 3G network and an Internet network. Multiple security monitoring and control computers are connected onto the security monitoring and control server through switches, and each security monitoring and control computer is connected with a safety alarm. Each gas delivery pipeline pressure measurement and control terminal comprises an ARM microcontroller module, a solar charging battery, a crystal oscillator circuit module, a reset circuit module, a data storage circuit module, a 3G module, a battery electricity quantity detecting circuit module, a press key operation circuit module, a pressure transmitter, an electric stop valve and a charging control circuit, wherein a solar cell panel is connected onto the charging control circuit. The natural gas well safety monitoring system achieves remote control of the electric stop valves, is high in intelligentization degree and working reliability, high in electric stop valve control efficiency and good in practicability and saves manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of natural gas safety production, in particular to a natural gas well safety monitoring system. Background technique [0002] For the sake of safety, a shut-off valve is installed on the gas transmission pipeline of each natural gas wellhead to prevent safety accidents when the pressure at the natural gas wellhead is too high or too low. The existing cut-off valve can automatically close the valve when the pipeline pressure is too high or too low, but it cannot be controlled remotely, and the real-time pressure data of the natural gas wellhead cannot be remotely grasped. When the valve needs to be closed or opened in an abnormal situation, the operator needs to When it comes to on-site operation, because most of the natural gas wells are located in deserts or sparsely populated places, the traffic is very inconvenient, so it cannot be timely and effective, and the safety and reliability are poor.
