Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Embodiment
The schematic diagram of the pick-up unit of a kind of locomotive equipment that Fig. 1 provides for the utility model embodiment.As shown in Figure 1, this device mainly comprises: wheel velocity generating unit, speed pickup information process unit, wheel speed information processing unit, sensor information diagnosis unit, speed sensor interface unit and sensor to be measured;
Wherein, described wheel speed information processing unit is connected with wheel velocity generating unit, speed pickup information process unit and sensor information diagnosis unit respectively; Described sensor one end to be measured is connected with wheel velocity generating unit, and the other end is connected with speed sensor interface unit; Described speed pickup information process unit one end is connected with speed sensor interface unit, and the other end is connected with sensor information diagnosis unit.
In the utility model embodiment, locomotive equipment can be realized by said structure relation and automatically detect, thus save a large amount of manpowers and time.
The principle of work of said apparatus as shown in Figure 2, mainly comprises three parts: the generation of target velocity curve, the collection of speed measuring equipment rate curve and data analysis and diagnosis; Specifically:
1, target velocity curve generating principle
Wheel speed information processing unit is according to parameter (wheel footpath value, the plus/minus velocity amplitude of input, Non-follow control instruction or automatically steering order etc.) generate the speed curves of motor, and passed to wheel velocity generating unit, generate actual wheel velocity test curve by wheel velocity generating unit.The real-time status of motor is fed back to wheel speed information processing unit by wheel velocity unit while actuating motor speed curves.
2, speed measuring equipment speed acquisition principle
Also drive tested sensor rotation while electric machine rotation in wheel velocity generating unit, thus target velocity curve is inputed to tested sensor.The rotation information measured is exported to speed sensor interface unit by the mode of simulating signal by tested sensor.The digital signal that the central processing unit being translated into speed pickup information process unit by the hardware circuit in speed sensor interface unit can process, its central processing unit calculates wheel movement information measured by current tested sensor by calculating the frequency of this digital signal and square wave number in conjunction with the wheel footpath value of tested wheel, and wherein wheel footpath value sends to speed pickup information process unit by wheel information processing unit with the form of message.
3, data analysis and diagnosis principle
Being input as of speed pickup information diagnosis unit: the wheel actual motion information of wheel speed information processing unit input, the wheel movement information of speed pickup information process unit input and strategy of reporting to the police.Comparative result and original information by compare the difference of two kinds of movable informations (comprising speed, direction and mileage value) in real time and combine the performance state that strategy of reporting to the police (judgment threshold of speed, direction and mileage value) judges tested sensor, and are generated detection log information by diagnosis unit in the form of a file.If find that there is the result exceeding judgment threshold, diagnosis unit by output alarm signal to inform that tester finds fault.
On the other hand, the present embodiment provides pick-up unit internal element to realize by following hardware:
Wheel velocity generating unit: motor and electric machine controller; Electric machine controller is responsible for receiving extraneous input command, then this order is converted into the signal of drive motor, makes motor produce corresponding action; Electric machine controller can also realize the feedback collection to motor action.
Speed pickup information process unit: embedded board; The digital signal that speed sensor interface unit produces by this board calculates according to wheel footpath value the wheel movement information that sensor measurement to be measured arrives.
Wheel speed information processing unit: embedded board+touch-screen; Touch-screen is responsible for receiving extraneous input command, embedded board is responsible for transferring extraneous input command to electric machine controller treatable signal, and the motor feedback signals that process gathers from electric machine controller, the actual motion information of current motor can be calculated thus, i.e. the movable information of wheel.
Sensor diagnostic unit: multi-purpose computer;
Speed sensor interface unit: embedded board; The simulating signal that sensor to be measured exports is converted into digital signal by this board.
The utility model embodiment by adopting motor simulation vehicle wheel rotation, the offline inspection of the distance-measuring equipment that can realize testing the speed, by the record of measurement result and analysis, the fault diagnosis of the distance-measuring equipment that can realize testing the speed; Said process is the testing process of robotization, has saved a large amount of manpowers and time; Meanwhile, the efficiency of maintenance job can be significantly improved.
