A large amount of leakages of oil, cause heavy losses.With developing rapidly for power industry, older generation's control based on relay contactor
System can not meet the various problems for being monitored under the unattended state of hot-oil circulation system and solving transformer oil in time.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of vacuum oil-filter remote monitoring system and method, subtract
Few hardware connection, reduction system failure frequency, mitigate the labor intensity of operations staff significantly, and safe and reliable.
The present invention is achieved by the following technical solutions：
Vacuum oil-filter remote monitoring system, including PLC, the PLC input connection signal every
From processor, input connection liquid level sensor, temperature sensor, pressure sensor and the flow of the signal isolation processor
Sensor, the output end of the PLC connects heater, alarm and oil transfer pump, the output of the PLC respectively
End is also by 3G module connection communication module, and the PLC connects mobile phone or desktop computer by the communication module.
Further, the communication module includes 3G, WiFi, Ethernet and wireless transport module.
Vacuum oil-filter long-distance monitoring method, this method is using above-mentioned vacuum oil-filter remote monitoring system, liquid
Level sensor, temperature sensor, pressure sensor and flow sensor monitor the various states of vacuum oil-filter in real time, and will prison
Liquid level, oil temperature, oil pressure and the flow measured is converted into electric signal, is carried out by signal isolation processor feeding PLC
Processing, PLC determines to carry out next step operation to vacuum oil-filter according to the various parameters value set before, if oily
It is warm not enough then to send information to heater and oil temperature is heated, if oil temperature is up to standard, stop the use of heater；If
Liquid level is too low, then starts the supply that oil transfer pump carries out oil mass, if liquid level is too high, stops the use of oil transfer pump；If oil pressure
More than setting value, then start alarm and stop the running of vacuum oil-filter；If the flow value that flow sensor is monitored is not
In the range of set value, then fuel-displaced valve is adjusted, fuel-displaced valve is connected with PLC using signal so that flow is accorded with
Standardization.PLC can be using being automatically controlled and controlling manually, and PLC is contacted by 3G module with communication module,
And communication module is connected by 3G, WiFi or Ethernet with mobile communication, communication module passes through wireless transport module and desk-top meter
Calculation machine or notebook computer communication connection, staff are controlled to PLC by mobile phone or computer, controlled by PLC
The data of device transmission processed are handled vacuum oil-filter accordingly.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention enters to the various status signals of vacuum oil-filter
Row in real time monitoring, then by signal isolation processor handle after feeding PLC handled, PLC it is automatic
Manipulation or manual manipulation pattern can carry out different processing for the different situations of vacuum oil-filter in time, it is to avoid cause people
A large amount of wastes of power, material resources, greatly improve operating efficiency, and ensure the safety of operating personnel.
Brief description of the drawings
Fig. 1 is the structural principle block diagram of the present invention.
Embodiment
Vacuum oil-filter remote monitoring system as shown in Figure 1, including PLC, the input of the PLC
Signal isolation processor is connected, input connection liquid level sensor, temperature sensor, the pressure of the signal isolation processor are passed
Sensor and flow sensor, the output end of the PLC connect heater, alarm and oil transfer pump, the PLC controls respectively
The output end of device processed also by 3G module connection communication module, the PLC by the communication module connect mobile phone or
Desktop computer.
Further, the communication module includes 3G, WiFi, Ethernet and wireless transport module, 3G, WiFi, Ethernet
With mobile communication, wireless transport module communicates with desktop computer or notebook computer.
Specifically workflow is：After oil transportation pump startup, in order that it is hydraulically full in pipeline, heater dry combustion method is prevented, with
It is too high and be burned as temperature, it is set to delay and starts for 3 minutes, when shutting down, heater first stops so that liquid is in the duct
Delay is shut down again after 3 minutes, heater can thoroughly be cooled down.Liquid level sensor, temperature sensor, pressure sensor
Monitor the various states of vacuum oil-filter in real time with flow sensor, and the liquid level monitored, oil temperature, oil pressure and flow are turned
Electric signal is changed to, is handled by signal isolation processor feeding PLC, it is each that PLC is set before
Plant parameter value to determine to carry out next step operation to vacuum oil-filter, if oil temperature not enough, sends information to heater to oil
Temperature is heated, if oil temperature is up to standard, stops the use of heater；If liquid level is too low, starts oil transfer pump and carry out oil mass
Supply, if liquid level is too high, stop oil transfer pump use；If oil pressure is more than setting value, starts alarm and stop
The running of vacuum oil-filter；If the flow value that flow sensor is monitored adjusts fuel-displaced not in the range of set value
Valve so that flow meets standard.PLC can be using automatically controlling and controlling manually, and PLC passes through 3G module
