Description
Technical field
This patent is related to mining comprehensive insurance system detection device, more particularly to the mining comprehensive insurance system based on PLC and industrial personal computer
Detection device.
Background technique
It is the supply main of underground coal mine, branch line, mobile substation, electronic with the raising of coal production the degree of automation
Various mining comprehensive insurance systems, mainly electromagnetic starter, core has been widely used in machine, electric coal drill, mine lighting signal etc.
Part is electronic synthetical protector and vacuum A. C. contactor.Working Environment of Underground Mine is severe, and comprehensive protection device and vacuum are handed over
Contactor is flowed it is possible that malfunction, due to comprehensive protection device and vacuum A. C. contactor important function, it is necessary to ensure that its
It is working properly, need to carry out routine test thus, new comprehensive protection device is using must be tested.
Existing detection device is mainly based upon traditional relay or monolithic processor controlled, and its structure is complicated, reliable
Property is poor, function is simple.
How to realize and electronic synthetical protector and vacuum A. C. contactor are detected, is currently urgently to be resolved ask
Topic.
Summary of the invention
To solve the above problems, the invention patent gives full play to the characteristics of PLC, provide a kind of based on PLC and industrial personal computer
Mining comprehensive insurance system detection device realizes the purpose detected to electronic synthetical protector and vacuum A. C. contactor.
The present invention is based on the mining comprehensive insurance system detection device of PLC and industrial personal computer the technical solution adopted is that:
Mining comprehensive insurance system detection device based on PLC and industrial personal computer, PLC is master controller, and display control device is industrial personal computer,
Industrial personal computer is connected by RS232 communication interface with PLC；
The master controller of the present apparatus is PLC, is detected by PLC and handles various input signals, and judges that testing result is
It is qualified or unqualified.Display device is industrial personal computer, can be operated by display device and see testing result with simple and clear.
Digital electronic ammeter, digital voltmeter, digital ohmmeter, the RS485 communication interface of voltage resistant instrument are each with industrial personal computer respectively
A USB interface is connected；
By adjustable electric current, voltage and resistance device, the electric current, voltage and resistance of output are shown in digital current
Table, digital voltmeter, on digital ohmmeter, and electric current, voltage and the resistance data that will test are transferred on industrial personal computer and PLC.
Overload signal, overload time, disconnected phase signals, the disconnected phase time, over-voltage signal, the over-voltage time, under-voltage signal, it is under-voltage when
Between, the starting of earth leakage search/lockout signal, synchronism detection, A timing, B be synchronised timing, the timing of timing, C that be synchronised that be synchronised reset, be resistance to
Pressure test starting is connected with the input terminal of PLC；
According to different electric current multiples, the overload time passed through when issuing overload signal according to comprehensive protection device passes through
PLC judges that under different electric current multiples, overload time is whether in acceptability limit, to judge whether overload protection is qualified.
Similarly, open-phase protection, overvoltage protection, under-voltage protection detection be also such.
The resistance value for adjusting adjustable resistor, earth leakage search/lockout resistance value when being issued according to earth leakage search/lockout signal, is sentenced by PLC
Disconnected whether earth leakage search/lockout resistance value is in acceptability limit at this time, so that whether the leakage latching protection for detecting comprehensive protection device closes
Lattice.
The synchronism detection starting of PLC input terminal is pressed, the control coil of the vacuum A. C. contactor of PLC output end is attracted,
Start vacuum A. C. contactor contact and is attracted synchronism detection.The A of PLC input terminal be synchronised timing, the C of timing, B that be synchronised is synchronised
Timing will be attracted, and connect the Millisecond timer in PLC, when calculating the actuation of the three-phase contact of vacuum A. C. contactor contact
Between, and pickup time is judged by PLC, to detect whether vacuum A. C. contactor contact pickup time synchronizes.It presses in time
It resets, from the new detection for carrying out vacuum A. C. contactor synchronization time.
The synchronism detection starting of PLC input terminal is pressed, enabling signal will be passed in voltage resistant instrument by industrial personal computer, thus real
Now to the resistance test of vacuum A. C. contactor contact.
Qualified indicator light, unqualified indicator light, loudspeaker and vacuum A. C. contactor control coil and PLC output end phase
Even.
By the indicator light of PLC output end, show whether above-mentioned testing result is qualified.When qualified, qualified indicator light is bright.No
When qualified, unqualified indicator light is bright, while loudspeaker make a sound.The control coil of vacuum A. C. contactor, control are true when measuring
The actuation and disconnection of empty ac contactor contact.
The beneficial effects of the present invention are: the mining comprehensive insurance system detection device based on PLC and industrial personal computer, is realized to mining comprehensive
The overload of electronic synthetical protector in insurance system, disconnected phase, over-voltage, under-voltage, earth leakage search/lockout detection, and vacuum communication is contacted
The synchronization pickup time of device and the detection of pressure resistance.Its structure is simple, easy to use, multiple functional, reliable performance.
