Background
The rapid development of urban rail transit plays an increasingly important role in meeting the travel demands of people, improving the supply quality and efficiency of urban public transit, relieving urban traffic jam, promoting the development of economic society and the like. With the development of computer technology and network technology, the control and management of subways become more intelligent and automatic, so that the guarantee of the normal operation of electrical equipment is very important.
The fire safety is an important component of the subway safety, and the mixed gas fire extinguishing system makes important contribution in the aspects of protecting the normal operation and the life and property safety of the subway in order to ensure the fire safety of the operation of electrical equipment.
The gas fire extinguishing system is in a standby state most of the time, but once a fire occurs, fire extinguishing needs to be started immediately, so that the safety of maintenance equipment is very important. The traditional gas fire extinguishing system does not monitor the state of the selector valve in real time, generally, operation and maintenance personnel regularly check whether the selector valve is in a closed state, and the check result is influenced by the subjective factors of the operation and maintenance personnel, such as the working capacity, attitude, responsibility, state and the like. The consequences are very severe once the selector valve is in the open state, which requires monitoring of the selector valve's normal state.
In order to ensure the use safety of the gas fire extinguishing system, the operation and maintenance personnel need to strengthen the monitoring of the pressure of the cylinder group while the sealing performance of the cylinder group is improved. In a traditional mixed gas fire extinguishing system, operation and maintenance personnel regularly go to a gas cylinder to observe the position of a pressure gauge pointer of each cylinder group and judge whether the pressure of the cylinder group is in a normal value range. This method has the following disadvantages:
1. the pressure gauge is usually a pointer pressure gauge, and can only be looked at horizontally during reading, so that the parallax error is large and the reading error is large.
2. The accurate pressure value cannot be read.
3. The mechanical pressure gauge has high damage rate under the condition of long-term pressure.
4. The operation and maintenance personnel have large workload and need to carry out full inspection at regular intervals.
