Abstract
The utility model discloses a wiring harness on-off detector comprising a main controller, the main controller is respectively connected with a power module, a display device, a CPLD controller, a memory and a man-machine interface, the display device is connected with the power module, and the CPLD controller is connected with an external connection wire switching terminal. The wiring harness on-off detector fills the gap of low-end detection products among detectors. The man-machine interface is designed into a key, full consideration is given to the operation habit of users, the interface layout is reasonable, and the design of the man-machine interface is more user-friendly. All ports of the detector are independent and can carry out detection mutually. After detection is completed, a detection result is directly fed back to the man-machine interface, users are enabled to see the result more intuitively through acousto-optic prompt, the detection speed and accuracy are improved, and the working cost is greatly reduced.
Description
Technical field
The utility model belongs to electronic technology field, for the judgement test of correcting errors of the break-make of automation controller and mechanical connection line (wire rod does not comprise relay, diode) and connecting pin position, is specifically related to a kind of wire harness break-make detector.
Background technology
Along with the fast development of electronic detector technology, more and more higher to the requirement of detection technique convenience, and existing tester seems that for the simple wire rod of test some is wasted one's talent on a petty job, and makes use cost too high.In some cases, generally for the break-make that only needs measurement circuit whether, just do not need to use the wire harness tester of a tester band measuring diode or triode, therefore, develop a kind of wire harness break-make detecting instrument of simple low grade, just seem very necessary.
The utility model content
The utility model provides a kind of wire harness break-make detector, has solved tester of the prior art for the simple wire rod of test, the problem that its use cost is too high.
The technical solution of the utility model is, a kind of wire harness break-make detector, comprise master controller, master controller is connected with power module, display device, CPLD controller, storer, man-machine interface respectively simultaneously, display device separately is connected with power module, and the CPLD controller separately is connected with the external connection conversion terminal.
Characteristics of the present utility model are to have filled up the blank of tester low and middle-end testing product.Man-machine interface is set to button, fully takes into account user's operating habit, and interface is arranged relatively reasonable, and the humanization designing of man-machine interface is stronger.Each port of tester is independently, can mutually test.After test completes, directly by the result feedback of test on man-machine interface, and, by acousto-optic hint, make the user can see more intuitively result, accelerate detection speed and accuracy, significantly reduced job costs.

In figure, 1. master controller, 2. power module, 3. display device, 4.CPLD controller, 5. external connection conversion terminal, 6. storer, 7. man-machine interface.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, the structure of the utility model wire harness break-make detector is, comprise master controller 1, master controller 1 is connected with power module 2, display device 3, CPLD controller 4, storer 6, man-machine interface 7 respectively simultaneously, display device 3 separately is connected with power module 2, and CPLD controller 4 separately is connected with external connection conversion terminal 5.
With reference to Fig. 2, master controller 1 is selected the STM32 type controller.
Storer 6(adopts SD card or USB flash disk, adopts usual general standard interface), carry out reading and writing data and data storage by processor SPI port.
The STM32 controller is controlled liquid crystal display by FSMC and is shown, by the order emission of total line traffic control key scan, CPLD controller 4 and feedback reception, the LED light of data, shows and audible alarm, by spi bus, carries out the storage of USB flash disk data; CPLD controller 4 receives the control signal test wire harness that the STM32 controller sends, carry out logical process after feedback data to the STM32 controller.
With reference to Fig. 2, mobile memory is the SD card, the SD cartoon is crossed spi bus and is electrically connected to the STM32 controller, the STM32 controller is connected with display screen by the FSMC mode, the STM32 controller is connected with LED alarm lamp and audible alarm in addition, the STM32 controller is connected with CPLD controller 4 by communication bus, and the interface of CPLD controller 4 is by two conversion terminals and the corresponding connection in wire rod to be measured two ends of external connection conversion terminal 5.
Man-machine interface 7 in embodiment 2 comprises liquid crystal display (demonstration) and touches touch screens (operation), and mobile memory is selected USB flash disk, identical with in embodiment 1 of other settings.
The design parameter by mobile memory, wire harness detected after sampling completes (comprising logical sum, the corresponding order of passage etc.), form with file copies on mobile memory, then by mobile memory, again these parameters and data Replica need to be produced on the equipment of same product to other, after having copied, the utility model equipment can arrange the parameter newly copied one time automatically, and other equipment just do not need reset and learnt like this.The automatic compare test device of wire harness of the present utility model, significantly reduction in the numbers of seconds, reduced testing cost and material loss, improved production efficiency.
