Embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figure 1, the winding displacement detection system described in the utility model embodiment comprises winding displacement, a N sampling end 20, the first test side 30 and the second test side 40.Described winding displacement has L root wire 10.The first paragraph of n root wire 10 and the first paragraph of the n ' root wire 10 in described L root wire 10 connect one to one with N sampling end 20 respectively.The second segment of the n root wire 10 in described L root wire 10 is all connected with the first test side 30 by just connecing one-way conduction element 50 separately, and the second segment of the n ' root wire 10 in described L root wire 10 is all connected with the second test side 40 by just connecing one-way conduction element 50 separately.In the present embodiment, described winding displacement is 25 core winding displacements, also has 25 sampling ends 20 simultaneously, that is to say N=L=25, c=0.A described N sampling end is corresponding L root wire 10 just, and the diverse location of n root wire 10 is detected in described the first test side 30 and the second test side 40.Particularly, described every wire 10 all has first paragraph, second segment and the 3rd section, and the level signal of described second segment is detected in described the first test side 30, and the level signal of described the 3rd section is detected in described the second test side 40.A described N sampling end 20, the first test side 30 and the second test side 40 are the GPIO(universal input/output of same single-chip microcomputer) mouthful.Bidirectional interface is all arranged in a described N sampling end 20, the first test side 30 and the second test side 40.Therefore utilize a single-chip microcomputer can realize the monitoring to winding displacement.Preferably, described the first test side 30 and the second test side 40 are respectively P0.1 mouth and the P0.2 mouths of single-chip microcomputer.Described one-way conduction element 50 is diode.Described the first test side 30, the second test side 40 are also connected with stake resistance 60.
In another embodiment, c=25, first thief hatch 20 need to connect the 1st with the first paragraph of the 26th wire, n thief hatch 20 connects the first paragraph of n root and the n ' root wire.Owing to differing 25 wires 10 between described n root and the n ' root wire 10, in objective reality, can not there is the situation of short circuit, therefore can share a thief hatch 20.Understandably, described c can be also other numerical value, as long as can guarantee that n root and the n ' root wire can not exist short-circuit conditions.
As shown in Figure 2, described in embodiment of the present utility model, winding displacement detection method comprises step:
If described n root wire is in connection situation, n root wire optional position is all with high level signal, if described n root wire is in the situation that opening circuit, high level signal ends at off position; If described the n ' root wire is in connection situation, the n ' root wire optional position is all with high level signal, if described the n ' root wire is in the situation that opening circuit, high level signal ends at off position;
The level signal of the second segment of described n root wire is detected in the first test side, described the n ' root wire level signal is detected in the second test side, when described n root wire is in connection situation, described the first test side receives high level signal, when described n root wire is in the situation that opening circuit, described the first test side receives low level signal, send alerting signal, when described the n ' root wire is in connection situation, described the second test side receives high level signal, when described the n ' root wire is in the situation that opening circuit, described the second test side receives low level signal, send alerting signal,
Detect other sampling ends in N sampling end, if other all sampling ends all receive low level, judge that described n root and the n ' root wire are normal, if m sampling end in N sampling end receives high level, judge described n root or/and the n ' root wire and m root wire are short-circuited, m ≠ n, m ≠ n '.
Described four steps that circulate, until detected each root of the N root wire in described winding displacement.
In the time of c=0, the diverse location of n root wire is detected in described the first test side and the second test side, in the time that one of them of described the first test side and the second test side receives low level signal, send alerting signal, thereby realize, the many places of n root wire are detected.
Understandably, in the time that N equals other numerical value, that is to say when winding displacement has other numerical value root wires 10, the number of transformed samples end 20 or by multiple conducting wires 10 divide into groups detect, can complete the detection of whole winding displacement, winding displacement detection method of the present utility model is utilized sampling end 20, the first test side 30 and the second test side 40, each wire 10 in winding displacement carried out to short circuit with the detection of opening circuit, thereby the qualification rate that can accurately control winding displacement is 100%, get rid of the fault causing because winding displacement is bad, enhance productivity.And because being utilizes the GPIO mouth of single-chip microcomputer to detect winding displacement, for single-chip microcomputer, what its GPIO mouth was exported and inputted is digital signal, 1 represents high level, and 0 represents low level.Therefore, winding displacement detection method can judge exactly high level and low level in judgement, fuzzy value in the middle of not existing.Have again, utilize the GPIO mouth of single-chip microcomputer to detect winding displacement, large-scale without utilizing, complicated even expensive testing tool, thus simplify winding displacement detection system, also reduce testing cost.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
