Background technology
The test of PLC product is whether bad in order to the product in testing producing lines if existing on hardware or software.Small PLC product, is divided into CPU element and expanding element two class.CPU element feature richness, the function ratio measured is more, generally needs that the On-off signal measuring body exports, analog input or output, communication interface (comprising RS485, RS232, CAN), SRAM power failure data keep functional test, the power supply of the test of RTC clock accuracy and EEPROM readwrite tests and expansion bus; Expanding element generally only measures corresponding function and expansion bus interface.
Small PLC system I/O counts general within 256 o'clock, and compact, low price, functional module are multiple, applying flexible, powerful.The PLC product line of general company, counts according to difference in functionality and control, and product category is at least more than 20 kinds.The product that so the different kind of several functions is multiple, when production test, each funtion part is tested complete again, test manually if adopted, test job amount is extremely large, also causes cost of goods manifactured greatly to increase, and manual testing also has sizable inconsistency simultaneously; If adopt tool fixture automatically to test, those more than 20 kinds of different products, may need to overlap different test fixtures and tool, so multiple types test fixture tool 20, need Meteorological comparatively large, application and maintenance also quite not easily more.
Utility model content
The purpose of this utility model is to provide a kind of PLC product automatic testing equipment being applicable to multiple PLC product test.
For solving technical matters of the present utility model, the utility model provides a kind of PLC product automatic testing equipment, it comprises the host computer connected successively, test fixture main frame and test wire harness, test wire harness is used for connecting tested PLC product and test fixture main frame, test fixture main frame comprises exterior strands interface, CPU and the two-way RS485 communication interface be connected with CPU respectively, one road RS232 communication interface, one tunnel CAN communication interface, 24 switch value input interface, 36 point relay output interfaces, 4 tunnels analogy amount input interfaces, 4 tunnels analogy amount output interfaces, exterior strands interface is by above-mentioned two-way RS485 communication interface, one road RS232 communication interface, one tunnel CAN communication interface, 24 switch value input interface, 36 point relay output interfaces, 4 tunnels analogy amount input interfaces, 4 tunnels analogy amount output interfaces are integrated on a connection interface.
Wherein, host computer is connected with test fixture main frame by RS232 communication interface.
Wherein, described test fixture main frame comprises the real-time clock be connected with CPU further.
Wherein, described test fixture main frame comprises power module further.
Wherein, described test fixture main frame adopts bakelite cabinet.
Wherein, described exterior strands interface adopts multicore aero seat.
Compared with prior art, PLC product automatic testing equipment of the present utility model is in conjunction with multiple PLC series of products functional characteristics, only use a test fixture main frame, complete the automatic test and calibration of multiple PLC series of products, test result accurately and reliably, simple to operate, easy to maintenance, substantially reduce in product manufacturing and test man-hour used, reduce production cost, improve production testing efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of PLC product automatic testing equipment of the present utility model.
Fig. 2 is the schematic diagram of the test fixture main frame in Fig. 1.
Embodiment
As shown in Figure 1, of the present utility model by PLC product automatic testing equipment comprise connect successively host computer, test fixture main frame and test wire harness.Host computer is undertaken being connected and communicating by RS232 communication interface and test fixture main frame.User issues test command by computing machine to test fixture main frame, and feedback test result.The precision of analog input and output in the concrete model of test product, the system time arranging test fixture main frame, calibration testing frock main frame can be set by computing machine and generate test log.Test fixture main frame under control of the computer, exports various test volume on request, carries out every test or staking-out work to test product.Test wire harness is used for connecting test frock main frame and tested PLC product.
As shown in Figure 2, test fixture main frame comprises power module, exterior strands interface, CPU and the two-way RS485 communication interface be connected with CPU respectively, a road RS232 communication interface, a road CAN communication interface, switch value input interface, 36 point relay output interfaces, 4 tunnels analogy amount input interfaces, 4 tunnels analogy amount output interfaces, real-time clocks at 24.Power module provides power supply for test fixture main frame each several part.Above-mentioned two-way RS485 communication interface, a road RS232 communication interface, a road CAN communication interface, 24 switch value input interface, 36 point relay output interfaces, 4 tunnels analogy amount input interfaces, 4 tunnels analogy amount output interfaces are integrated on a connection interface, so that be connected with PLC product by exterior strands interface.These interfaces can be supplied to corresponding product as test volume or scalar quantity.CPU is used for testing test product according to arranging of user.Test fixture main frame adopts bakelite cabinet.Exterior strands interface can adopt multicore aero seat, and convenient the carrying out with testing wire harness is transferred.
Test wire harness is used for connecting test product and test fixture main frame.The function different according to each product, is connected to the exterior strands interface of required test volume from test fixture main frame the pluggable terminal of surveyed product by test wire harness.Powered to test product by test wire harness, facilitate the control of testing process.Adopt test fixture main frame and test wire harness separate mode, single test fixture main frame is suitable for the product test of whole PLC product line, and different test wire harness is applicable to different products.
