Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described further.

Before test, correctly connect system, before certain type cable is carried out path testing, carry out two work by Fig. 1: the one, cable wireless test instrument is carried out self check, guarantee that cable wireless test instrument self is working properly; The 2nd, it is known to have set up these cable standard data or cable annexation in the cable data storehouse.Fig. 5 is a cable wireless test instrument workflow diagram.

The self check of cable wireless test instrument is carried out in conjunction with transit cable, checks when realizing this machine with transit cable.Self check is divided into the short circuit self check and the self check of opening circuit.Before the self check wireless control module linked to each other with the USB mouth with the com port of main frame, wherein COM is used to transmit test command, receives various test datas, and the com port address is optional; The USB mouth is responsible for giving wireless control module for power supply.Require one of transit cable to connect the wireless test module during short circuit self check, the other end is unsettled, on main frame, select " transit cable short-circuit detecting " item, module C sends out control command for simultaneously modules A and module B, modules A, B control every output high level successively by cable plug core number, in this output high level by the input port with all plug level retakings of a year or grade, if certain level point is then this point and measured some short circuit of height, can realize test for short-circuit by the height of interpretation interface level like this.In the level of retaking of a year or grade, comprised the level that sends the contact of high level, realized the input/output function of each interface of test module is carried out complete detection, improved the accuracy rate of test result by internal loopback.When opening circuit self check, the patchplug free end is connected short circuit plug, on main frame, select " transit cable open circuit detections " item, module C sends out control command for modules A and module B, modules A, B are controlled every output high level successively by cable plug core number, under the normal condition input port measure have a few and all should be high level.

After self check finishes, the other end of transit cable is connected respectively on the tested cable, respectively with wireless test modules A B ground connection, earthing cable can be connected on the car body during to vehicle-mounted wireline test. select the wireline test order on main frame, module C sends out control command for simultaneously modules A and module B, at first test cell voltage separately, and send host computer to show the voltage measurements, this electromechanics amount lamp was glittering when cell voltage was not enough, and buzzer warning, host computer provide corresponding information; After entering test period, A module main control MCU is put height successively with its P0 mouth level, control 1 driver of gating by the SPI mouth by CPLD, the output high level signal, the input matrix of this machine of gating successively, each interface level is checked, check the annexation of A mouth cable, import detection by wireless data transmission module control B module simultaneously, measure the annexation of A end cable and B end cable, solved the test problem of multi-multipoint stube cable, 8 pio chips of gating are realized the test to 64 core cables successively; The A module testing finishes the back and carries out same operation by the B module, obtain another group test data, by host computer two groups of test datas are checked alternately, guarantee precision of test result. after test was finished, hummer provided cue, and test result is carried out interpretation by host computer according to the normal data in the database, mode with tabulation on screen provides the cable annexation intuitively, the wrong cable period, type of error is realized the cable through test very easily.

For unknown cable, need before test, set up the standard cable database.Database establish dual mode: a kind of is manually to add according to the explanation of cable, marks out standard cable by the cable period; The 2nd, select a cable working properly, test its path situation as stated above, it is saved as standard cable automatically, with the benchmark of this cable data as other similar wireline test.

The wireless cable tester is realized the product test compatibility by selecting the coupling of dissimilar transit cable realizations to various model plugs.The test specification of single wireless test module is 64 cores, and each module has the address setting switch, realizes the module cascade by different addresses, finishes the test of the complicated cable system of multicore.

Native system adopts the intelligent electric power management technology, digital transmission module has the Remote Wake Up function, enter dormant state by Single-chip Controlling after finishing test assignment, the power supply by other peripheral interface circuits such as relay control disconnection CPLD and drivers effectively prolongs the testing of equipment time.

Cable wireless test instrument respectively has a module at tested cable two ends, and two intermodules do not have the constraint of stube cable, need not tested cable unloaded and just can carry out break-make and detect, plug is fixed onboard and the cable of apart from each other, improved the convenience of maintenance efficiency and use greatly.
