External owing to having flourishing automobile industry, the particularly U.S., Japan, and some countries of Europe, the testing techniques of equipment being associated with automobile industry also has very high level.In recent years, Japanese Nike (NAC) company develops the wire harness conduction detector of various new in succession, mixes corresponding test fixture, after once plugging together, by instrument internal DLC (digital logic circuit), can very convenient, accurately, promptly carry out wire harness conduction detection.But at present part instrument price is more expensive, has limited applying of it, the domestic test macro that only has the joint large-scale wire harness of minority manufacturing enterprise to use a complete set of import.For various reasons domestic, to start late, no matter the domestic equipment detecting for automotive wire bundle is at technical elements and aspect of performance, or aspect reliability, compares and still have very large distance with external equipment.So as a rule, automotive wire bundle manufacturer still adopts traditional detection method, or depends on import equipment.
Develop a domestic automotive wire bundle checkout equipment very necessary, to improving China's automotive wire bundle test and quality control level, have great significance, vehicle failure rate is greatly reduced, improved the security of automobile, have economic benefit and social benefit widely.
Utility model content
The technical problems to be solved in the utility model is for the deficiencies in the prior art, to provide a kind of automobile primary cable detecting device, to be applicable to the test of various different model wire harness.
The purpose of this utility model is to provide a kind of automobile primary cable detecting device, in the middle of in body, be provided with the control function that controller is realized whole pick-up unit, on controller, be connected with communicator and realize the upper and lower computer communication function with management system, display screen, data-carrier store is realized the storage of normal data and the interim memory function of test data, tester is realized wire harness connection status test function, restorer is realized the function restarting and the alarm of whole device and is realized fault type prompting and sound alarm function, on display screen right side, be connected with keyboard, keyboard is also connected on controller, realizing pick-up unit function selects and inputoutput data Presentation Function, the interior upper right corner of body is provided with power supply and is connected to power with all parts.
Further improve and be: tester comprises 6 passage reverse buffer SN7406, the data buffer 74LS244 of 8,3-8 line code translator 74LS138.
Further improve and be: alarm comprises four independently warning lamp and hummers.
Further improve and be: controller is that LPC2119 controller is as the core of whole pick-up unit.
Further improve and be: power supply is LM1117 power supply, and the model of data-carrier store is CAT24WC32 storer.
The beneficial effects of the utility model: by adopting said structure, can manage and store the mass data of wire harness test, and be connected with host computer by communicator, handled easily personnel check wire harness test case and demonstration on-line testing process, and can expand as required measurement capacity, thereby can test the wire harness of Multiple Type and store data, will greatly reduce the labour intensity of wire harness test, increase work efficiency, strengthen the accuracy of test.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1-body, 2-controller, 3-communicator, 4-display screen, 5-keyboard, 6-data-carrier store, 7-tester, 8-restorer, 9-alarm, 10-power supply, 11-warning lamp, 12-hummer.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in Figure 1, the present embodiment provides a kind of automobile primary cable detection dress dress, core component is controller 1, controller 1 respectively with communicator 3, data-carrier store 6, tester 7, display screen 4, be connected to the keyboard 5 on display screen 4, restorer 8 and alarm 9 links, controller adopts ARM chip LPC2119 as the control controller of hardware platform, selects 8255 and 74 series digit chips to realize test terminal circuit, set up serial communication and realize upper and lower computer data sharing, and by system transplantation, realize the optimum control of hardware platform.
Described restorer 8 is comprised of MAX708, /button of MR termination, button other end ground connection, when button is pressed, can produce a low level pulse and deliver in reseting generator, thereby produce the output of 200ms reset pulse, then pass through triple gate 74HC125 to controller transmitted reset signal.
Keyboard 5 and display screen 4 adopt ZLG7289A intelligent control chip, include the de-jitter of keyboard 5, in practical operation, after a button is pressed, can cause interrupt request, after by controller 2 response, interrupted, reading which key in keyboard 5 has been pressed, and then according to key assignments, call relevant keyboard 5 and process function, complete the operation response to keyboard 5.
First according to wiring diagram, write wire harness coding schedule, and convert normal data (line group and termination) to, if these data are in not storage before this, enter data into detection system and be stored in data-carrier store, if known storage data are directly called.Wire harness to be measured is connected on test interface plate, and generally, port has all been made card format, to adapt to the needs of mass detection.Then start to detect operation, and judged whether fault, if the fault of existence shows location of fault and alarm, no matter have inerrancy, all the result store of this detection is got up.
