Abstract
The utility model discloses an offline fault diagnosis device for a medium-low pressure fuel gas pressure regulator, which comprises two pressure measurement transmitters, a field data recorder, a mobile data memory, and a data processing and fault diagnosis main unit. The two pressure measurement transmitters are arranged on a pipeline on one side of a medium pressure fuel gas pipeline and a pipeline on one side of a low pressure fuel gas pipeline respectively. The data output ends of the two pressure measurement transmitters are connected with the field data recorder. The field data recorder is in timed connection with a mobile data unit to transmit field data, and then the field data are copied to the data processing and fault diagnosis main unit. The offline fault diagnosis device can achieve the technical effects that the safety data of the medium-low pressure fuel gas pressure regulator are collected and processed in real time, and faults are diagnosed automatically.
Description
Technical field
The utility model relates to a kind of gas safety detection technology.
Background technology
Mesolow gas pressure regulator, governor in actual use, there will be fault, and generally can be embodied in the pressure values of its import and export, in order to guarantee the security of operation of mesolow gas pressure regulator, governor, just need to, to above-mentioned real time data acquisition, regularly process.
Utility model content
The purpose of this utility model is to provide a kind of mesolow gas pressure regulator, governor Off-line faults diagnosis device, to solve the service data of centering low-pressure fuel gas pressure regulator, carries out Real-time Collection and processes the technical matters of automatic diagnosis fault.
In order to realize foregoing invention object, the technical scheme that the utility model place is used is as follows:
A mesolow gas pressure regulator, governor Off-line faults diagnosis device, comprises two pressure measurement transmitter, data recording field instrument, movable data storer, data processing and fault diagnosis main frame; Described two pressure measurement transmitter are arranged on respectively on medium pressure gas pipeline one side of mesolow gas pressure regulator, governor and the pipeline of low-pressure fuel gas pipeline one side, gather and import and export pressure values, its data output end is connected with the data recording field instrument that measured value is carried out to digital-to-analog conversion and correction, and data recording field instrument has internal storage; Described data recording field instrument is regularly connected transmission field data with movable data storer, this movable data storer by data-interface to data processing and fault diagnosis host duplication field data.
The utlity model has the effect of real-time storage field data, timing transmission and off-line automatic analysis fault.
Accompanying drawing explanation
Fig. 1 is the theory diagram of a kind of mesolow gas pressure regulator, governor Off-line faults diagnosis device of the present invention.
Accompanying drawing number: 1, medium pressure gas pipeline, 2, intake pressure measuring transducer, 3, gas pressure regulator, governor, 4, top hole pressure measuring transducer, 5, low-pressure fuel gas pipeline, 6. data recording field instrument, 7, movable data storer, 8, data processing and fault diagnosis main frame, 9, reading out data line, 10, unloading data line.
Embodiment
A kind of mesolow gas pressure regulator, governor Off-line faults diagnosis apparatus structure of the present invention is referring to Fig. 1.This device comprises: two pressure measurement transmitter 2,4, data recording field instrument 6, movable data storer 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; After data recording field instrument 6 is undertaken by measured value that necessary modulus (A/D) transforms and revises, according to the data acquiring frequency of setting, intake pressure and top hole pressure measured value and Measuring Time are stored in to internal storage; The data conversion storage of regularly data recording field instrument 6 being stored, to movable data storer 7, then copies to record data data processing and fault diagnosis main frame 8; Data processing and fault diagnosis main frame 8 carry out off-line data processing and analysis according to specific data processing algorithm to the mesolow gas pressure regulator, governor intake pressure obtaining and top hole pressure measured value, and according to analysis result automatic diagnosis pressure regulator fault.
The job step of above-mentioned a kind of mesolow gas pressure regulator, governor off-line safety early warning device is as follows:
1) operational factors such as measuring transducer automatic monitor for continuously mesolow gas pressure regulator, governor import pressure, back pressure value and environment temperature are set, at the scene, utilize data recording field instrument to record at the scene service data;
2) service data that, data processing and fault diagnosis main frame obtain by data recording field instrument off-line 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 analysis of spectrum 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.
