The signal output part of described PLC control module also is connected with an alarm unit.
The utility model can be differentiated the parameter attribute of product automatically according to the product bar code, carries out test mechanical life and load the breaker of plastic casing rated current automatically measuring loop resistance, judges phase shortage, slide fastener, the resistance upper limit and record data automatically; By interface operation easily, realize from normal moveout correction, inquiry, printing function; DATA REASONING precision height, convenient and swift; Establish database, can conveniently inquire about and review historical record.
Description of drawings
Fig. 1 is systematic schematic diagram of the present utility model.
Embodiment
As shown in the figure, breaker of plastic casing intelligent detection and control system of the present utility model includes a PLC control module, the signal input part of PLC control module be connected with respectively to read the test product bar code mark barcode scanner, be used for importing execution command control knob, be used for detecting the output circuit feedback unit of each output circuit (comprise and carry out control circuit, mechanical on off test circuit, resistance measuring circuit) feedback signal; The control signal output terminal of PLC control module connects the mechanical on off test circuit of carrying out control circuit, being used for testing each phase on off operating mode of test product, resistance measuring circuit, the alarm unit that can measure each phase loop voltage of test product and current signal respectively; The detection signal input resistance test module of resistance measuring circuit; PLC control module and resistance test module are respectively by communication module and an industrial computer swap data.
In the said system:
Industrial computer 1 realizes that by communication module 11 and 2 communications of PLC control module industrial computer is to the exchanges data of PLC;
PLC control module 2 with barcode scanner 21 serial communications, the data of barcode scanner 21 are received carry out communication operation, and give industrial computer 1 by PLC with bar code value and decode, take out the parameter of product.
The I/O delivery outlet of PLC control module 2 connects control knob 11, output signal feedback unit 12, realizes the control to equipment operation process;
The I/O delivery outlet of PLC control module 2 connects the cylinder solenoid valve of carrying out in the control circuit 25, realizes clamping and divide-shut brake control to product.
The I/O delivery outlet of the PLC control module 2 tool on off test circuit 26 that picks, for PLC when the product breaking-closing operating, judge that Product Status provides a test loop.
The I/O delivery outlet connecting resistance metering circuit 27 of PLC control module 2 realizes the effective disconnection to mechanical on off test loop, connects the measurement loop of product and resistance test module 3 in the anchor clamps simultaneously, and the voltage signal of each phase of product is sent into resistance test module 23.
The I/O delivery outlet unit taking alarm of PLC control module 2,28, realize the unusual external alert prompting of product test.
Industrial computer 1 receives each phase resistance data that resistance test module 3 is measured by communication module 12, the ModbusRTU agreement is adopted in communication, resistance test module 3 test philosophies are the electric current and voltage method, its state is just to be in the real-time testing state after the device power-up, data are desirable at any time, and 1 of industrial computer is in the data that just read resistance test module 3 under the steady state (SS) at the resistance test electric current also to be handled.
The course of work of the present utility model is as follows:
Product is put into test fixture, after control knob 11 starts, PLC control module 2 sends enabled instruction and makes barcode scanner 21 work, upper industrial computer 1 is real-time and PLC communication by the function variable of configuration program, receives bar code value character string and the decoding of PLC data field, accesses relevant information by the bar code rule from the bar code prescription: as the framework electric current, rated current, the dropout mode, number of poles, resistance higher limit etc.
When bar code is effective, industrial computer 1 makes interface or control knob 22 inputs be in state of activation, the enabling signal input effectively, PLC control module 2 is connected mechanical on off test circuit 26, and feeds back to the clamping of PLC control module 2 deactivations, divide-shut brake topworks by the program work of setting by output signal feedback unit 23.PLC judges according on off test circuit 26 feedback signals whether phase shortage or slide fastener are arranged during each the combined floodgate, normally then finishes test mechanical life by set point number, otherwise connects alarm unit 28, and be presented at industrial computer 1 interface information hurdle.It is out of service to control topworks simultaneously, receives the reset signal at control knob 22 or interface up to PLC control module 2, returns original state.
PLC 2 is after mechanical test finishes, disconnect mechanical on off test circuit 26, connect resistance measuring circuit 27, resistance test module 3 is in real-time measurement state, and industrial computer 1 receives the resistance value data of resistance test module 3, and after the resistance value of reading in deducted modified value, compare with the resistance higher limit in the bar code prescription, the result is presented at the interface and is saved in the database automatically, and off resistance metering circuit 27, original state is got back to by system.Resistance is defective, starts PLC control module 2 by industrial computer 1 and connects alarm circuit, and original state is got back to by the back system up to resetting.
