The circuit structure of a kind of mesolow gas pressure regulator, governor safety on line prior-warning device of the present invention is referring to Fig. 1.This device comprises: two pressure measurement transmitter 2,4, data recording field instrument 6, data communication unit 7, data processing and fault diagnosis main frames 8.
Two pressure measurement transmitter 2,4 detect respectively mesolow gas pressure regulator, governor import pressure and back pressure value and it are sent to data recording field instrument 6 in real time; Data recording field instrument 6 carries out measured value after necessary modulus (A/D) conversion and correction, according to the data acquiring frequency of setting, inlet pressure and outlet pressure measured value to be sent to data communication unit 7; Data communication unit 7 is sent to data processing and fault diagnosis main frame 8 in the mode of wired or wireless communication in real time by inlet pressure and outlet pressure measured value; Data processing and fault diagnosis main frame 8 carry out data processing and analysis and automatically send the early warning of pressure governor security of operation according to analysis result the mesolow gas pressure regulator, governor inlet pressure obtaining and outlet pressure measured value with specific data processing cycle according to specific data processing algorithm; The safe early warning that data processing and fault diagnosis main frame 8 finally send can be realized by host display prompting, acoustooptic alarm, the modes such as designated telephone, transmission text prompt note that dial to upper-position unit transmission alarm signal, automatic speech.
The job step of above-mentioned mesolow gas pressure regulator, governor safety on line prior-warning device is as follows:
1) Operational Limitss such as measuring transducer automatic monitor for continuously mesolow gas pressure regulator, governor import pressure, back pressure value and ambient temperature are set, at the scene, and utilize data recording field instrument and information transfer channel to be sent in real time data processing and fault diagnosis main frame;
2) service data that, data processing and fault diagnosis main frame obtain online by information transfer channel according to time series take regular time step-length and the time cycle carry out Spectrum Analysis as unit, intelligent trouble diagnosis main frame compares aforementioned waves spectrum analysis result and the typical fault Spectral Characteristic that research obtains in advance and identify, and according to the result comparing and identify, makes fault diagnosis conclusion;
3), intelligent trouble diagnosis main frame is made fault diagnosis conclusion and is found and automatically sends the warning of pressure governor operation troubles after fault, operator check and confirm or eliminate reporting to the police according to service data record and personal experience, and intelligent trouble diagnosis main frame will be checked situation according to operator and automatically revise typical wave spectrum knowledge base;
4), the intelligent trouble diagnosis main frame result that compares, identify according to aforementioned waves spectrum analysis and typical fault Spectral Characteristic, and with reference to before the historical data variation tendency of a period of time, pressure governor security of operation is carried out to early warning
