Controller and measuring module communicate with measuring probe by switch, and manipulator is 3-DOF manipulator. The problems that efficient of manual testing in background techniques is low, precision is bad, and cost is high because of testing system is used in a few testing are resolved. The present invention is used for detecting cable device or device connected with cable in process of research, produce, detection, usage and maintains, especially for detecting cable with different capability and specification in laboratory.
Description
Technical field
The present invention relates to a kind of checkout equipment of detection streamer, can be used for developing, produce, check, cable or have the detection of the equipment of cable connection in the use, maintenance process, be particularly useful for that the cable to different performance, different size detects in the laboratory.
Background technology
Cable is the important carrier that electromechanical equipment carries out signal transmission or power transfer, and the power supply between the system equipment, signal, control, communications all will be finished by cable.The reliability that cable connects directly has influence on the serviceability rate of equipment.Therefore in the development of electronic product, production, check, use, maintenance process, all need cable is detected.
The operational ton of wireline test is huge, generally needs heart yearn and the measurement parameter that every heart yearn of the cable other end is communicated with successively of test cable one end, detects number of times and is generally: N=n (n-1)/2, and wherein N is for checking number of times, n is that the detection of wire harness is counted.For example: 36 core cables, n=36 detects times N and is generally 630 times.
The classic method of wireline test mainly is the manual testing, adopts instruments such as avometer, hummer, and two people cooperate, and artificial pointwise is tested, and is applicable to the wireline test that kind is few, the core number is less.For test in enormous quantities, polycore cable, not only testing efficiency is low, and influenced by human factor, causes easily that conducting contact is unreliable, test leakage etc., poor accuracy.
The formation of existing polycore cable test macro by transit cable 9 and adaptive socket 10, can be carried out thermometrically to tie cable between different systems, subsystem, the unit or the passive electric performance that has the equipment of cable as shown in Figure 1.Concrete grammar is: plug 4 is passed through to insert in tested cable 6 two ends, 5 are connected with adaptive socket 10, by man-machine interface 1 input controlled variable, controller 2 starts measurement module 3, make measurement module 3 be in conducting, impedance, insulation waits one of measurement state, controller 2 is by demoder 7, switch matrix 8 and transit cable 9 that driver and relay constitute, pumping signal is delivered to the access plug 4 of tested cable 6 through adaptive socket 10,5, switch matrix 8 is successively with the input end conducting of the every heart yearn and the measurement module 3 of tested cable 6, test result is sent controller 2 and man-machine interface 1 back to, controller 2 is analyzed, judge the conducting of tested cable 6, measurement parameter such as impedance or insulation, the break-make road that can find heart yearn, the overlap joint short circuit, distribution mistake etc.The shortcoming that existing polycore cable test macro exists is: the polycore cable of different performance, different size, need to adopt different special-purpose adaptive sockets 10, and be only applicable to cable batch process of less types or keep in repair occasion in batches.
In most laboratory and maintenance sites, often need the polycore cable of multiple different size be detected, a kind of cable under test of specification may have only one sometimes.Adopt manual test, carry out above troublesome operation hundreds of times, time-consuming, effort, and poor accuracy.Adopt existing polycore cable test macro, must make corresponding transit cable and adaptive socket, cost is higher.In addition, existing test macro is that the High-Voltage Insulation test of adopting switch matrix 8 to finish each root heart yearn is switched, each relay need keep certain safe distance when wiring, relay quantity in the switch matrix 8 is directly proportional with tested cable core number, when relay quantity more for a long time, the volume of test macro can be very huge.
