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.

Abstract

The invention discloses an unattended natural gas monitoring system which comprises a controller. The input end of the controller is connected with a plurality of sensors, and the sensors comprise the pressure sensors and the flammable gas detector. The output end of the controller is further connected with an alarm and a wireless communication module, and the wireless communication module is one or more of a Wi-Fi module, a Bluetooth module, a GPRS module and an LAN interface module. The output end of the controller is further connected with a compressor and / or valve executing mechanism control module. The system provided by the invention can achieve unattended operation of natural gas stations easily, the operating situation of the system can be easily judged in real time, technical parameters can be easily adjusted and controlled in real time, and during application of natural gas, the system is higher in safety and reliability, lower in equipment or pipeline operating cost and easier to operate, and achieves local unattended operation of the natural gas stations.

Description

technical field [0001] The invention relates to the field of cryogenic fluid delivery pipelines, in particular to an unattended natural gas monitoring system. Background technique [0002] Natural gas is a high-quality clean energy, and the strategic position of natural gas in the energy structure of developed countries has long been established. It is used in a wide range of fields, such as chemical industry raw materials, industrial fuels, commercial and civil fuels, automobile fuels, central heating and power generation, etc. It is one of the main one-time consumption energy. The implementation of my country's "West-to-East Gas Pipeline" plan shows that the country attaches great importance to the utilization of natural gas. Although my country started late, its development momentum is strong. It can be seen that my country's natural gas source supply has ushered in a dawn, and the prospects are bright. Natural gas utilization projects in various places are expected to q...
