Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to limit of the present utility model
System.
The electric motor car low voltage wiring harness detection device proposed according to this utility model embodiment is described with reference to the accompanying drawings.
Fig. 1 is the block diagram of the electric motor car low voltage wiring harness detection device according to one embodiment of this utility model.Such as Fig. 1
Shown in, this electric motor car low voltage wiring harness detection device includes: first passage selection circuit 100, second channel selection circuit 200
With single-chip microcomputer 300.
Wherein, first passage selection circuit 100 includes first input end and multiple outfan, and multiple outfans are treated in order to connect
First end of survey line bundle, the second channel selection circuit 200 corresponding with first passage selection circuit 100 includes the second outfan
With multiple inputs, multiple inputs are in order to connect the second end of wire harness to be measured.The output port of single-chip microcomputer 300 and second defeated
Entering end to be connected, the input port of single-chip microcomputer 300 is connected with first input end, and single-chip microcomputer 300 is by first passage selection circuit
100 and second channel selection circuit 200 select sense channel, and sent to the sense channel selected by output port and identify
Signal, and receive identification signal to detect the connection status of wire harness to be measured and to connect line sequence by input port.
Specifically, when needing the low voltage wiring harness of electric motor car is detected, second channel selection circuit 200 can be first passed through
Selecting a port of the first end of wire harness to be measured, single-chip microcomputer 300 sends identification signal by output port to this port, as
High level or low level signal.Then, selected the port of the first end of wire harness to be measured by first passage selection circuit 100,
And detected by the port of the input port of single-chip microcomputer 300 first end to selecting, to judge wire harness according to testing result
Connection line sequence；Or testing result is compared with the wire harness port mapping table being stored in advance in single-chip microcomputer 300,
The most correct to judge that wire harness connects；Or directly any two port in detection wire harness port connects the most correct, not only
Improve the speed to low voltage wiring harness detection, and strong adaptability, the most error-prone and be easily achieved digitized, be conducive to carrying
High productivity.
According to an embodiment of the present utility model, the level signal exported by output port when single-chip microcomputer 300 and single-chip microcomputer
When 300 level signals received by input port are identical, wire harness to be measured is in connected state.
It is to say, send low level or low level signal by single-chip microcomputer 300 to the second end of low voltage wiring harness, pass through simultaneously
Single-chip microcomputer 300 detects the signal of the first end of low voltage wiring harness.If the signal sent is identical with the signal of detection, then it represents that this
Two ports are in connected state；If the signal sent is different from the signal of detection, then it represents that the two port is not in even
Logical state.Then, testing result is compared with the wire harness port mapping table being stored in advance in single-chip microcomputer 300,
The most correct to judge the annexation of wire harness；Or the connection line sequence of wire harness is judged according to testing result；Or realize correspondence
The lookup of wire harness port.
Such as, when the annexation judging wire harness is the most correct, the single-chip microcomputer 300 second end to low voltage wiring harness is first passed through
First port sends low level signal, if single-chip microcomputer 300 detects that the first port of the first end of low voltage wiring harness is low level
Signal, and be consistent with the corresponding relation arranged in wire harness port mapping table, then just judging the connection of the two port
Really, then the second port to the first end of low voltage wiring harness carries out detection and judges；If the result of detection is corresponding with wire harness port
The corresponding relation arranged in relation table does not corresponds, then judge that the annexation of the two port is incorrect.
And for example, when judging the connection line sequence of wire harness, first pass through the first port of the single-chip microcomputer 300 second end to low voltage wiring harness
Send low level signal, if single-chip microcomputer 300 detects that the first port of the first end of low voltage wiring harness is high level signal, then
Representing that the two port is in connected state, single-chip microcomputer 300 records testing result；If the first end of the low voltage wiring harness of detection
The first port be low level, then it represents that the two port is not in connected state, now needs the first end to low voltage wiring harness
The second port detect, circulate successively, until the end that the first port of the second end with low voltage wiring harness is connected being detected
Mouthful, and record testing result.Then, the second port of the second end of low voltage wiring harness is detected, circulates successively, until
Complete the detection to wire harness all of the port, finally obtain the line sequence of low voltage wiring harness according to testing result.
It is understood that concrete detection method has multiple, repeat no more here, and the detection device of the embodiment of the present invention
It is possible not only to the low voltage wiring harness of electric motor car is detected, it is also possible to other low voltage wiring harness is detected.

Enter channel selecting signal to select sense channel.
Specifically, as in figure 2 it is shown, work as first passage selection circuit 100 and second channel selection circuit 200 by multiple 38
When decoder is constituted, when needing the first port selecting the first end of low voltage wiring harness, can be by the numeral of single-chip microcomputer 300
Outfan output channel select signal (such as high level or low level signal) to address end S1, S2 and S3 of decoder 1,
And ensure S1=" 1 " (high level), S2=" 0 " (low level), S3=" 0 ", now the outfan D1 quilt of decoder 1 '
Select.Single-chip microcomputer 300, is now decoded to the first outfan IO of decoder 1 ' by output port output low level signal
It is low level signal on first port of second end that signal is low level signal, i.e. low voltage wiring harness of the outfan D1 of device 1.
Meanwhile, address end S1, S2 and S3 of single-chip microcomputer 300 output channel selection signal to decoder 1, and ensure S1=" 1 ",
S2=" 0 ", S3=" 0 ", then the outfan D1 of decoder 1 is chosen.Single-chip microcomputer 300 detects decoder by input port
The signal of the first input end IO of 1, i.e. the signal of the outfan D1 of detection decoder 1, is also the first end of low voltage wiring harness
The first port on signal.If the signal of now single-chip microcomputer 300 detection is low level signal, then it represents that low voltage wiring harness
First port of the first end and the first port of the second end are connected, and otherwise two ports are in non-connected state.Then, single
According to testing result, sheet machine 300 judges whether low voltage wiring harness connects correctly, or judge the line sequence of low voltage wiring harness, concrete before
Face has been described above, and repeats no more here.
