The initial position of flaw detection trolley contacts with the first proximity switch, in the embodiment of the present application, as shown in figure 5, should
Method may comprise steps of.
S101, turning using the distance between first position-limit mechanism and second position-limit mechanism and the motor
Speed, calculates the flaw detection trolley by the motion duration between first position-limit mechanism and the second position-limit mechanism, and determines bag
Duration containing the motion duration is interval.
Because dolly is when mobile, it is impossible to accomplish between actual location position and ideal position completely always, so at this
In application embodiment, the error range of a permission can be set.By taking motion duration t0 as an example, duration interval can select be
[t0-5s, t0+5s], i.e. the time end with 5 seconds before and after motion duration are interval as duration.
S102, after the flaw detection trolley setting in motion, when first proximity switch stops generating trigger, opens
Beginning timing, obtains timing duration.
First proximity switch is when flaw detection trolley is in initial position, as shown in fig. 6, trigger is persistently produced, but it is little
After car movement, the induction module of the first proximity switch and trigger module are separated, and then the trigger of the first proximity switch is interrupted.
For example by Fig. 6 to Fig. 7, flaw detection trolley starts to be moved right along track.
S103, in the flaw detection trolley motion process, when any one of smooth electric switch detector exports count signal
When, stored count obtains count value.
As shown in fig. 7, due to the position of baffle plate it is corresponding with the position of light electric switch detector, when each light electric switch detector
By baffle plate position, light electric switch detector can be formed and be blocked, so by the count detection of light electric switch detector, can
To judge which probe is moved to the position that baffle plate is located on current flaw detection trolley.
S104, when the timing duration be located at the duration it is interval in, second proximity switch output trigger and
When the count value is equal to the quantity of all probes, determine the flaw detection trolley without positioning failure.
In this step, if timing duration is equal to, duration is interval, namely the movement position of dolly is located at the error for allowing
In the range of.Second proximity switch exports trigger, represents that the second proximity switch contacts with the second position-limit mechanism 17, and second connects
Closely switch equivalent to travel switch, this on the other hand, the run location of dolly has arrived extreme position, such as Fig. 8 institutes
Show.
Count value is equal to the quantity of all probes, represents that all probes have been moved to roller-way lower section, namely flaw detection trolley
Preferable flaw detection position is moved to.
By three condition comprehensive descisions above, it can be deduced that flaw detection trolley runs under the running parameter of setting
Position is consistent with ideal position, and positioning scenarios are accurate, meets the requirements.So when these three conditions are satisfied by, can be true
Determine failure of the flaw detection trolley not in terms of positioning.

And the count value less than all probes quantity when, determine the flaw detection trolley positioning failure, and generate Fisrt fault signal.
In this step, when the minimum of a value that timing duration is interval less than duration, represent that the second position-limit mechanism distance first is limited
The setpoint distance when actual range of position mechanism is interval more than calculating duration, so, it is little when dolly runs according to setpoint distance
The second proximity switch on car cannot touch the second position-limit mechanism, therefore, there is Wrong localization.Now need technical staff couple
First proximity switch or the first position-limit mechanism, and, the position of the second proximity switch or the second position-limit mechanism is adjusted.
In the application other embodiments, the method can also be comprised the following steps：
When the timing duration minimum of a value interval less than the duration, second proximity switch output trigger and
When the count value is equal to the quantity of all probes, the flaw detection trolley positioning failure is determined, and generate the second fault-signal.
In this embodiment, although the timing duration minimum of a value interval less than duration, but due to the output of the second proximity switch
Trigger, and quantity of the quantity equal to all probes of popping one's head in, illustrate that dolly has moved to preferable flaw detection position, now table
Bright flaw detection trolley motion is too fast, advances to up to preferable flaw detection position, therefore, there is Wrong localization, now need technical staff couple
The slewing rate of the motor on flaw detection trolley is adjusted.
In the application other embodiments, the method can also be comprised the following steps.
When the timing duration maximum interval more than the duration, second proximity switch output trigger and
When count value is equal to the quantity of all probes, the flaw detection trolley positioning failure is determined, and generate the 3rd fault-signal.
In this embodiment, although the second proximity switch exports trigger, and count value is equal to the number of all probes
Amount, but due to the timing duration maximum interval more than duration, so flaw detection trolley still Wrong localization.In this case, go out
Existing location of fault is probably that the distance between the first position-limit mechanism and the second position-limit mechanism arrange wrong, and now technical staff needs
Will to the first proximity switch of flaw detection trolley or the first position-limit mechanism, and, the position of the second proximity switch or the second position-limit mechanism
Put and be adjusted.
In the application other embodiments, the method can also include step.
When the timely duration maximum interval more than the duration, second proximity switch do not export trigger
And count value less than all probes quantity when, determine the flaw detection trolley positioning failure, and generate the 4th fault-signal.
In this embodiment, three conditions mentioned above, neither one condition meets, then illustrate now flaw detection trolley
Position complete mistake, it is therefore desirable to which technical staff is adjusted to parameter again, is then tested again.
In the embodiment of the present application, the method can also be comprised the following steps.
When it is determined that the flaw detection trolley is without positioning failure or when there is positioning failure, generating brake signal, and by the system
Dynamic signal is sent to the motor.
No matter that assignment test result, is required to control motor to stop operating, and then flaw detection trolley is stopped
Motion, to avoid causing to damage to motor.In addition, in practical application, to be on the safe side, can be with close second
During switch output trigger, regardless of detection and localization result, motor will be controlled and shut down, this is due to when the
Two proximity switches export trigger, represent that flaw detection trolley has moved to extreme position, if now motor still turns
It is dynamic, then the problems such as causing motor damage or dolly to de-orbit appearance may occur.
In the embodiment of the present application, the method can also be comprised the following steps.
When generating Fisrt fault signal, the second fault-signal or the 3rd fault-signal, by the Fisrt fault signal, second
Fault-signal and the 3rd fault-signal are sent to preset failure alarm, so that the alarm is reported to the police.
Reported to the police by alarm, can quickly allow technical staff to know and positioning failure occur, subsequently to be examined
Survey and debug.In addition, for different fault-signals, when being reported to the police, can also make a distinction, so that technical staff can be with
Fault type is quickly distinguished, and then more targetedly carries out malfunction test.
