Embodiment
As Fig. 2, shown in Figure 3, a kind of automobile, the automatic monitor station of motorcycle main cable, comprise the power supply, display 6, control knob, the connector that are connected with each circuit, one end of described leader cable is connected with single chip machine controlling circuit 3 input ends by connector, input circuit 1, input isolation circuit 2, and single chip machine controlling circuit 3 output terminals are connected with the other end of leader cable by output isolation circuit 4, output circuit 5, connector; Single chip machine controlling circuit 3 also is connected with programmable device 7; Single chip machine controlling circuit 3 is made up of singlechip chip, interface circuit 8, singlechip chip is connected with display 6, warning circuit 9, programmable device 7, input circuit 1, output circuit 5 by interface circuit 8 respectively, and singlechip chip 10 is connected with scratch pad memory 12 with storer 11.Control program leaves in the storer 11 in the single chip machine controlling circuit 3, and programming data leaves in the scratch pad memory 12.Storer 11 models are EPROM2764, and scratch pad memory 12 models are E
2PROM2816A.
Single chip machine controlling circuit 3 is to be responsible for detected transmission signal, storage data, to judge that whether normal leader cable etc.; display 6 is to be responsible for showing whether leader cable is normal; or trouble spot and fault category; programmable device 7 is the data that are used to import different model automobile, motorcycle main cable; buffer circuit is to be used to protect single chip machine controlling circuit 3; output circuit 5 is to be used for exporting respectively the 5V electric signal, and input circuit 1 is to be used to receive electric signal.Single chip machine controlling circuit 3 mainly is made up of 51 series monolithics 10 and relevant interface circuit 8; control program leaves in and solidifies in the storer; programming data leaves in the scratch pad memory; has power-off protection function; at first the data of each model leader cable are imported data by programmable device 7 in scratch pad memory 12 by interface circuit 8; buffer circuit is in order to guarantee that equipment can normally stably be worked in abominable production environment; because this system interface quantity is more; for economizer port; interface circuit 8 has adopted by multi-disc 74LS138 decoding scheme to be formed; to save port and chip, both saved cost, also make checkout equipment work more reliable.
, can not only arbitrarily store test figure, and increase the dirigibility and the versatility of equipment greatly as the control core with single-chip microcomputer, make checkout equipment have intellectuality.
Concrete detection method is, be numbered at first for automobile, a motorcycle main cable, number respectively line group and termination, with first termination numbering of wired group among 1~40, compile all the other terminations is among 60~100, such as, a certain line group # is the Line 1 group, and this line group has three terminations, as shown in Figure 4, wherein first termination is numbered 1, the 2,3 termination and is numbered 60,61 respectively.
Judge whether a leader cable is qualified, mainly be check see if there is open circuit, short circuit and wrong line, it is local obstructed that what is called opens circuit and should lead to exactly, so-called short circuit is exactly that the termination that should not lead to has led to, so-called wrong line is exactly to wait two terminations to install anti-, termination that should be logical is illogical, and what should not lead to is logical.
After the number of finishing,, can detect automatically as long as operating personnel click the Automatic Detection and Control button, the first step is the detection of opening circuit, and detecting then is a line group, the sequence detection of a line group, at first add+5V voltage for first termination of a line group by output circuit, by receiving circuit, receive the voltage of these other terminations of line group then, compare with the normal data of this model leader cable of programmable device input then, if it is correct, then check next line group,, show the trouble spot if incorrect then report to the police; Second step was a short-circuit detecting, be equally to first end of a certain line group first+5V voltage, whether the termination of checking other line group then has logical, if have then show this termination short circuit, then report to the police and show the trouble spot, if not then check next line group, the 3rd step was that wrong line detects, and was first termination+5V voltage to a line group equally, and whether detect this other termination of line group then obstructed, whether the termination of detecting other line groups again has logical, certain termination as this line group is obstructed, and the termination of other line groups has led to, and then shows wrong line, then report to the police and show the trouble spot, if not then continue to detect automatically next line group.When above three steps detect finish after, all not discovery open circuit, the situation of short circuit, wrong line, illustrate that then this leader cable is qualified.The leader cable of different model, its mode of connection can be input in the single chip machine controlling circuit 3 by programmable device 7 and store in the storer, thereby realizes the purpose of general detection.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
