Detailed description of the invention
Fig. 1 is the principle of the present invention block diagram.
Specific embodiment
Referring to Fig.1, a kind of intelligent switchboard online monitoring method device, including operation control terminal, transmitter module and match electrical measurement
Measure module.Wherein operation control terminal includes main control module, communication module, switching value acquisition module, display module, relay output mould
Block and processing module.Operation control terminal is powered with guide tracked power supply adaptor, and the operating voltage of operation control terminal is 24V.Transmitter
The AC power source of the external 220V of module.The communication module of operation control terminal is RS485 communication interface, and transmitter module is also equipped with
RS485 communication interface, transmitter module is connect with operation control terminal by communication bus and the two is with Modbus-Rtu protocol communication.
Switchgear is provided with several radio temperature sensors, and radio temperature sensor surveys the temperature of the sampled point in switchgear
Amount, sampled point are the line contacts of component in cabinet.Radio temperature sensor integrates ZigBee sending module, transmitter module collection
At ZigBee receiving module, the temperature of the sampled point measured is sent to by radio temperature sensor by ZigBee wireless signal
Transmitter module, transmitter module, which is converted the temperature information received, makes the information that can be steered terminal recognition
And the temperature information after conversion is sent to operation control terminal.The temperature information received is stored in memory module by operation control terminal.
Main control module compares the temperature value in the temperature information received with setting value, if the former is greater than the latter, main control module is raw
At high temperature alarm signal, operation control terminal sends high temperature alarm signal to the host computer of operation duty room, and display module shows this
High temperature alarm signal, operations staff in duty room can timely learning switch cabinet temperature it is excessively high.The switching value of operation control terminal is adopted
Egf block is used to acquire the status information of route disconnecting link, breaker etc..The relay output module of operation control terminal is used for control cabinet
The movement such as interior blower, heater, dehumidifier.Voltage transformer and current transformer are installed in switchgear, wherein voltage is mutual
Sensor is used to acquire the voltage at the sampled point both ends for being added in component；And current transformer is for acquiring the sampling for flowing through component
The electric current of point.The output end of voltage transformer and current transformer is connect with the input terminal with electrical measuring module.With electrical measurement mould
Block integrates RS485 communication interface, is connect with operation control terminal by communication bus and with electrical measuring module with Modbus-Rtu agreement
Communication.Guide tracked power supply is provides the operating voltage of 5V with electrical measuring module.The output end of voltage transformer and current transformer
It is connect with the signal input part of operation control terminal, voltage transformer and current transformer are by collected information of voltage and current information
It is sent to operation control terminal.The voltage and current information received is stored in memory module by operation control terminal.In addition, in switchgear
Several humidity sensors are also equipped with, humidity sensor is connect with transmitter module, wet in the cabinet that humidity sensor will test
Degree information is sent to transmitter module, and operation control terminal is converted and be sent to humidity information by transmitter module, and main control module will connect
The humidity value in humidity information received is compared with setting value, and when the former is greater than the latter, main control module generates high humility report
Alert signal, operation control terminal send high humility alarm signal to host computer.
The built-in program for drawing waveform of the processing module of operation control terminal, the temperature that processing module receives operation control terminal are believed
Breath and voltage and current information are depicted as the waveform diagram of temperature signal and the waveform diagram of voltage and current signals with time shaft.
The display module of operation control terminal is touching display screen, and operation control terminal carries interactive interface, for operations staff and operation control terminal into
Row human-computer interaction.Touching display screen shows the waveform of temperature signal and the waveform of voltage and current signals.Pass through
Voltage waveform, operations staff can learn whether the operating voltage of component is stable.Alignment algorithm built in processing module, based on
It calculates the jump range of voltage signal and compares the lifting trend of the waveform of temperature signal and the waveform of current signal.The algorithm is any
It takes the voltage value at a time point compared with standard voltage value, finds out the absolute value of the difference of two values, by absolute value and reference value
Compare size, if the former is less than the latter, in normal range (NR), the operating voltage of component is opposite for the jump of account for voltage signal
Stablize；It is on the contrary then unstable.The algorithm transfer any two time point t1 and t2 temperature value T1 and T2 and current value I1 and
I1 and I2 are subtracted each other and obtain difference C1 by I2, and T1 and T2 are subtracted each other and obtain difference C2, later by both C1, C2 and zero balancing judgement
It is positive and negative.If C1 and C2 are positive number or are negative, illustrate that the waveform of temperature signal and the lifting of the waveform of current signal become
Gesture is consistent, is otherwise exactly that lifting trend is inconsistent.For the component of normal work, the calorific value of component and the electricity for flowing through it
Stream size is directly related, and the electric current for flowing through component increases, and the calorific value of component just will increase, otherwise will reduce.If stream
Electric current through component, which becomes smaller, but component temperature goes up not down or flows through the electric current of component becomes larger but the temperature of component
Anti- drop is not risen, illustrates that component is likely to occur failure.In this case, processing module generates abnormality alarming information, manipulation
Terminal sends abnormality alarming information to host computer, while touching display screen shows the abnormality alarming information.
After operations staff learns high temperature alarm signal, rushes towards scene and inspection is carried out to abnormal switchgear, operations staff can
It is steady in operating voltage to check temperature signal waveform, waveform voltage signal and current signal waveform from touching display screen
Under the premise of fixed, if current signal waveform is consistent with the lifting trend of temperature signal waveform, component failure can be excluded substantially
The case where, at this time it is considered that it is as caused by load excessive that switch cabinet temperature is excessively high, limitation load is can be improved in operations staff
Mode come give switchgear cooling；If current signal waveform and the lifting trend of temperature signal waveform are inconsistent, it can be determined that be
Component failure, it should investigation maintenance be carried out to component in cabinet, eliminated safe hidden trouble.
The present invention is other than the running state monitoring to switchgear, moreover it is possible to rough analysis offer for sale in whether have a component therefore
Barrier, facilitates operation and maintenance.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
