Abstract
The invention discloses a natural gas station yard monitoring method. An RTU (remote terminal unit) distanced from a pipeline by 20-30m is arranged to collect detection signals of electronic devices in a station yard and transmit the detection signals to a monitoring center, and the RTU is also capable of debugging flow at an exit, so that safety at client positions is guaranteed. The natural gas station yard monitoring method has the advantages that the RTU distant from the pipeline is arranged and is connected to the electronic devices via anti-explosion cables, signals are concentratedly transmitted, and the problem of signal confusion is avoided; the RTU is capable of instantly controlling an electric control valve to adjust the flow entering the client, a large amount of time is saved, and accidents happened when workers are on the way to debugging are avoided.
Description
Technical field
The present invention relates to rock gas delivery flow rate control field, particularly relate to a kind of natural gas station method for supervising.
Background technology
In rock gas transmission, a battlefield monitoring generally all can be set combustion gas is divided when defeated, in case minute defeated flow is not right, cause that to be transported to client's combustion gas air pressure not right, there is so sometimes unpredictable accident, because becoming the instrument greatly client being used, combustion gas air pressure has very large pressure, when excessive, may cause these instrument damage, phenomenon even leaks air, so the flow of combustion gas needs strict monitoring, but in existing gas monitor and control system, various instruments are all separately by a GPRS module, send to the Surveillance center of far-end, signal source too much causes signal easily to occur entanglement, make dropout.And existing supervisory system only can test out that to enter client's gas flow excessive, may cause going wrong, this needs staff to regulate to scene, has wasted a large amount of time.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of natural gas station method for supervising is provided, solve existing station farm monitoring system, the terminal that lacks a United Dispatching, each detecting instrument transmits a signal to respectively Surveillance center, easily there is signal entanglement, and need manual shift to enter client's gas flow, there is the shortcoming of losing time.
The present invention is achieved through the following technical solutions: natural gas station method for supervising, comprises the following steps:
(1) at station, conduit entrance place arranges intelligent flow meter and motorized valve, and each exit of a pipeline of standing arranges intelligent flow meter and electric control valve, set temperature transmitter and pressure unit on the pipeline in the field of standing;
(2) in step (1), the data of intelligent flow meter, temperature transmitter and pressure unit test are all sent to from the RTU of gas pipeline 20-30m through anti-explosion cable, RTU compares the flow value that enters the field of standing at any time with the flow that flows out field, station, when transmission error is larger, transmit a signal to motorized valve, shutoff combustion gas transmission, and transmit a signal to Surveillance center, by staff, check whether there be local leakage;
(3) the RTU data that monitoring temperature transmitter and pressure unit send at any time, when gaseous-pressure breaks bounds in pipeline, turn-off motorized valve, pressure recover normal after, then open motorized valve; When temperature breaks bounds in pipeline, send warning track Surveillance center, by staff, implement cooling and process;
(4) RTU, by the flow value of each outlet of intelligent flow meter monitoring station field, when certain station field flow amount breaks bounds, regulates the electric control valve of this outlet, until receive that the flow value of intelligent flow meter transmission is normal.
Described station field conduit entrance place is provided with a component detector, and its output is connected to RTU, when RTU receives component data and goes wrong, turn-offs motorized valve, and sends warning to Surveillance center, has staff to process.
The invention has the beneficial effects as follows: arrange one away from the RTU of pipeline, RTU is connected to each electron device by anti-explosion cable, thereby concentrate transmitted signal, avoided the problem of signal entanglement; RTU can control the instantaneous adjusting of electric control valve and enter client's flow, has not only saved a large amount of time, also avoids staff to go to regulate in way and has just occurred accident.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
