3, by changing PLC into by the work of manual measurement record braking electrical voltage point in former brake unit test process, automatically gather and record;
4, the automatic record product serial number by barcode machine brush bar code PLC will need be changed by the operation of manual record product serial number in former brake unit test process;
5, by needing artificial judgment test result in former brake unit test process, whether qualified operation changes by host computer automatic decision, prevents from judging by accident failing to judge;
6, will in former brake unit test process, need change by host computer printing test and report by the operation of manual record test result, improve testing efficiency.
Accompanying drawing explanation
Fig. 1 is the syndeton block diagram of interior each parts of test board casing in the utility model brake unit automatically testing platform.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model brake unit automatically testing platform comprises test board casing and is arranged at regulating circuit, rectification circuit, host computer, PLC, relay and the Acquisition Circuit among test board casing.The direct current terminals of tested brake unit are connected with rectification circuit, and resistor wiring end is connected with Acquisition Circuit, and braking gear wire jumper end is connected with relay; Described Acquisition Circuit is connected with PLC respectively with relay; Host computer is connected with PLC communication.
Regulating circuit is connected with rectification circuit, is used to brake unit test platform to provide LINEAR CONTINUOUS adjustable clean high-voltage DC power supply.
Acquisition Circuit is for detection of the make-and-break signal of direct supply magnitude of voltage and tested brake unit, the magnitude of voltage of direct supply is given the analog input port of PLC by light-coupled isolation, the make-and-break signal of brake unit is converted to through light-coupled isolation the digital quantity input port that rising edge signal is delivered to PLC.
According to host computer, receive from manually-operated tested brake unit braking gear switch instruction, by the digital output port controlling actuating of relay of PLC, realize the automatic switchover of tested brake unit braking gear.PLC is according to the data of digital quantity input port and the reception of analog input port, automatically record test data.Receive while opening signal rising edge, direct supply magnitude of voltage is now recorded as to the turning-on voltage value of corresponding tested brake unit; While receiving cut-off signals rising edge, direct supply magnitude of voltage is now recorded as to the shutoff voltage value of corresponding tested brake unit.
Host computer shows the test value of PLC record in real time, and turning-on voltage value and the shutoff voltage value of the tested brake unit that host computer collects PLC judge, judge whether tested brake unit is specification product.After test finishes, host computer printout test result.
