Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
The method of cable detection of the present invention is: set up the detection loop of trigger pip-controller-first level indicator-cable under test-inferior level indicator-constituted over the ground, the mode that adopts poll is the connection status of detection streamer inside conductor successively; First lead of test in the present embodiment: in the measuring head place in circuit, end with cable under test is a height, through cable under test and time level indicator (50 light emitting diodes of present embodiment employing, here connect wherein one) to ground, if cable connects normal, brighten as two corresponding light emitting diodes in first level indicator and time level indicator, otherwise, light emitting diode do not work (that is: not have a light emitting diode be bright for first level indicator and time level indicator, as can be known cable under test generation open circuit fault); If just a corresponding light emitting diode brightens in the level indicator, and has two above light emitting diodes to brighten in the inferior level indicator, the cable under test roadblock that is short-circuited as can be known;
It is manual or automatic that the inventive method can be selected detecting pattern.Under manual mode, by establishing the selection knob, be the clock source with the step-by-step impulse at the controller input end, produce the step-by-step impulse under the manual mode, carry out single step and detect.Under automatic mode, at the controller input end switching signal is set, selecting crystal oscillator is the clock source, by the assay intervals time is set, according to the specification of cable under test, selects the interface of different size, realizes the detection of plurality of specifications cable.
As shown in Figure 1, equipment therefor of the present invention comprises: receive the controller of detecting pattern signal, have control program, be used for control detection leg speed and process; Receive the first level indicator of the detection instruction of controller, link to each other with cable under test through primary connector; Cable under test constitutes and detects the loop again through primary connector, inferior level indicator ground connection.
Described controller (present embodiment employing VLSI (very large scale integrated circuit)) drives level indicator just, and pass through primary connector, cable under test, secondary connector, inferior level indicator to ground, by observing the indication of first level indicator and respective secondary indicator, in order to judge the connection status of cable under test, realize the function of detection streamer.
Consider the line number of detection streamer in the power consumption of circuit and the practical application, present embodiment selects for use 50 I/O pins as the first level indicator of drive end-promptly, needs and can expand if having.These pins are connected on the primary connector (as the IDC socket of 50 cores) through light emitting diode respectively, then through cable under test, secondary connector (the IDC socket of another 50 core), pass through time level indicator (other 50 light emitting diodes) respectively again and be connected to ground.
Controller counts according to the setting of outside input circuit, and through inner decoding output, the driven for emitting lights diode brightens.
As shown in Figure 2, be specially: controller U1 (adopting chip epm7128slc84-10), input circuit is by a toggle switch S2, reset button S1 and crystal oscillator U2 constitute, their output is connected respectively to the control pin of controller U1, when toggle switch S2 is set to 000000, select manual mode, the pulse that the knob S1 that resets produces provides clock signal for controller U1, when toggle switch S2 is set to 100000, select automatic mode, crystal oscillator U2 provides clock signal for controller U1.50 I/O pins of controller U1 connect the positive terminal of 50 light emitting diodes (first level indicator P2) respectively, and the negative pole end of these 50 light emitting diodes (first level indicator P2) is connected on the pin of an IDC50 socket (primary connector P1) back to cable under test; The pin one termination cable under test of another IDC50 socket (secondary connector P3), the other end is connected respectively to the positive terminal of other 50 light emitting diodes (inferior level indicator P4), and the negative pole end of these other 50 light emitting diodes (inferior level indicator P4) arrives ground by resistor chain P5.
Control program particular flow sheet as shown in Figure 3, show: after system powers on, controller carries out initialization earlier, judge then whether the work at present pattern is manual mode, if manual mode, then selecting step-by-step impulse is the clock source, and if not then being automatic mode, selecting crystal oscillator U2 is the clock source.Controller begins counting, and through decoding output, judges then whether training in rotation finishes, if do not finish, continues counting.If finishing to return, training in rotation begins to continue to judge the work at present pattern.
