Real-time monitoring system for gas station flows

Abstract

The invention discloses a real-time monitoring system for gas station flows. The system comprises a communication module in butt joint with an intelligent flow meter for transmitting flow data to a MCU, the MCU for regulating all modules and receiving the data information transmitted by the communication module and integrating the data information, LORA wireless module with a model number of F8L10and used for transmitting the integrated flow data in a wide range, an accumulator adopting a nickel hydrogen rechargeable battery and used for providing stable working voltage, a DC / CD converter forconverting output voltage of the accumulator to match with power supply voltage of the intelligent flow meter, and an unified expansion interface for expanding a connecting path between the MCU and an external module. The mounting position of the system is nearer the intelligent meter, and the induction pulse introduced by connecting cable lengths in the distance section is too low to threaten the intelligent flow meter; and batteries are used for supplying electricity without needing an external power grid, so that the safety is high, and the lightning strokes are directly prevented from introducing the pulse through the power grid.

Description

technical field [0001] The invention relates to the field of remote collection of natural gas, in particular to a real-time monitoring system for gas station flow. Background technique [0002] In some low-permeability areas of our country, the exploitation of natural gas is also in full swing. If natural gas is exploited in these areas, high-density natural gas wells are required to obtain high natural gas production. Therefore, tens of thousands of natural gas wells are distributed in a county-level administrative region. Due to the large number of wellheads, they may be distributed in deserts. In the Gobi, the inspection is very inconvenient, and the gas field must be managed digitally and networked. Therefore, it is necessary to have a supporting natural gas wellhead data collection and remote transmission system. In the natural gas wellhead data acquisition system in the prior art, the remote terminal control unit RTU (RemoteTerminal Unit) collects wellhead oil pressur...

If natural gas is exploited in these areas, high-density natural gas wells are required to obtain high natural gas production. Therefore, tens of thousands of natural gas wells are distributed in a county-level administrative region. Due to the large number of wellheads, they may be distributed in deserts. In the Gobi, the inspection is very inconvenient, and the gas field must be managed digitally and networked. Therefore, it is necessary to have a supporting natural gas wellhead data collection and remote transmission system

In the natural gas wellhead data acquisition system in the prior art, the remote terminal control unit RTU (RemoteTerminal Unit) collects wellhead oil pressure, casing pressure and natural gas flow data in the natural gas export pipeline through the analog input channel. However, the data acquisition cannot be completed for equipment above four cluster well groups. Moreover, the natural gas wellhead data acquisition system in the prior art still has defects and deficiencies such as high power consumption, poor safety performance, and high maintenance costs after failure.
