The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of natural gas station supervising device is provided, solve existing station farm monitoring system, signal source is excessive, easily causes the defect of dropout.
The present invention is achieved through the following technical solutions: natural gas station supervising device, comprise the intelligent flow meter that is arranged on a station conduit entrance and outlet, be arranged on the component analysis instrument of a station conduit entrance, be arranged on the motorized valve of a station conduit entrance, be arranged on the pressure unit on the pipeline of station, differential pressure transmitter, temperature transmitter, setting is away from the RTU of transmission pipeline, the output of described intelligent flow meter is connected to RTU, the output of component analysis instrument connects RTU, pressure unit, the output terminal of temperature transmitter is all connected to RTU through a signal isolator respectively, the control end of described motorized valve is connected to PLC controller, the control end of PLC controller is connected to RTU, RTU is connected to the control center of far-end through a signal is far passed module.
The information that this device gathers by the various instruments of RTU centralized collection, then send to the control center of far-end, RTU is remote data terminal, for monitoring, the application of control and data acquisition, have remote measurement, remote signalling, remote regulating, distant control function, it has the following advantages: the (1) programming language environment of standard; (2) extremely strong adaptive capacity to environment, ℃-70 ℃, working temperature-40, ambient humidity 5%-95%RH; (3) extremely strong anti-electromagnetic interference capability; (4) multiple standards communication protocol; Abundant communication interface, support communication (such as data radio station, GPRS etc.), communication distance long; (6) large capacity storage capability; (7) real-time multi-task operating system; (8) flexible compatible open interface.
Why not existing supervisory system arranges a terminal is gathered signal, and unification sends to Surveillance center, thinks terminal Instrumental more complicated, working temperature is very high, is placed on station, if gas leakage, be easy to light combustion gas, so generally all allow testing tool send voluntarily.
This device is that a RTU is set, and this RTU, away from station, away from pipeline, is connected to each monitoring instrument by anti-explosion cable, has not only realized the object of gathering signal, has also avoided gas leakage, the possibility of the equipment explosion that may cause.
In this device, the gas discharge that intelligent flow meter test input arrives at a station, and the flow of output station field, both should be consistent, if different, have problem, and component analysis instrument is monitored the component of rock gas, pressure unit, temperature transmitter be monitor force and temperature respectively, motorized valve, Surveillance center is thought while going wrong, and carries out Remote and turn-offs blast tube.
Further, the output port place of above-mentioned intelligent flow meter is provided with signal lightning arrester; The output port of component analysis instrument is provided with signal lightning arrester; The output port of pressure unit, temperature transmitter is all provided with a signal lightning arrester; Between motorized valve and PLC controller, be provided with signal lightning arrester.Signal lightning arrester is mainly when sending superpotential or surging, automatic shutoff circuit, thus protected electron device.
Further, above-mentioned field, station pipeline exit is provided with an electric control valve, and electric control valve is connected to RTU through PLC controller; general a plurality of outlet; each exports out an electric control valve is set, and electric control valve is used for regulating the flow of transmission, thereby has protected client.
Further, between above-mentioned electric control valve and PLC controller, be provided with signal lightning arrester, protection electron device.
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.
