Embodiment 1
[0019] like figure 1 , an unattended natural gas monitoring system, including a controller, the input of the controller is connected with a plurality of sensors, the sensors include a pressure sensor, a combustible gas detector, and the output of the controller is also connected with an alarm device and wireless communication module, the wireless communication module is one or more of Wi-Fi module, bluetooth module, GPRS module, LAN interface module, the output end of the controller is also controlled with the compressor and / or valve actuator The modules are connected.
[0020] Specifically, the set pressure sensor is used for air pressure detection. The above air pressure may include the gas pressure of the natural gas compressor, the gas storage well or storage tank, and the pipeline gas pressure. The set controller is used to judge the above signals to output alarm signals to the alarm or input control signals to compressors and valve actuators. The set wireless communicat...
Embodiment 2
[0022] like figure 1 , this embodiment is further limited on the basis of embodiment 1: in order to facilitate multi-point air pressure detection at multiple natural gas stations, there is more than one pressure sensor.
[0023] In order to further improve the safety of system operation, a hydrogen sulfide detector is also connected to the input end of the controller.
[0024] In order to further improve the controllability of the process parameters of the system, a water dew point detector is also connected to the input end of the controller.
[0025] In order to further improve the controllability of the process parameters of the system, the output terminals of the controller are also respectively connected with the water pump control module, the fan control module and the dryer control module.
[0026] In order to further improve the controllability of the process parameters of the system, a temperature sensor is also connected to the input end of the controller.
Embodiment 3
[0028] like figure 1 , this embodiment is further defined on the basis of any one of the technical solutions of any one of the above embodiments: in order to facilitate the intuitiveness of the alarm output, the alarm is an audible and visual alarm.
