And 42 voltage value of solenoid valve is normal and current value is abnormal, then can determine that as component failure itself.The electric current of motor 41 also with power
It is related, if hydraulic oil is very few in system, it may also lead to the reduction of 41 electric current of motor, need to judge in conjunction with motor speed at this time, if turning
Fast exception is then determined as electrical fault, if revolving speed is normal, current anomaly then may be that hydraulic oil is very few.And attitude transducer 44
With storage card 43 directly by whether data and signal can be obtained as the foundation for judging whether failure.
Step 4: display end 13 of the first microprocessor 11 by the comparison result in user's operation mould group 10 is shown
Show.For example, showing power failure, electrical fault, solenoid valve failure, attitude transducer failure or storage card event on display end 13
Barrier.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
