For example, the contents of the first memory and the second memory with the same operation time are read respectively, and the contents are compared to determine whether the contents are consistent, whether the start time, the end time and the operation are consistent, whether the operation is consistent with the change of the angle, and whether the operation time is consistent with the change of the angle. The accuracy of the recorded content can be determined by these comparisons. Therefore, accurate information such as operation time, operation content, movement posture change and the like can be obtained, and whether the operation of the operator is correct and reasonable during the operation can be judged.
An example of the process of the present invention is presented below to further illustrate the present invention.
When an action key is pressed at an operation end, the first microprocessor judges whether the key is pressed for the first time, if so, the time and the key value at the moment are stored in the first memory, meanwhile, the key information is sent to the second microprocessor through the CAN bus, the second microprocessor judges whether the instruction is received for the first time after receiving the action instruction, if so, the sensor value at the moment is read, the time, the instruction and the angle value information obtained by the sensor at the moment are stored in the second memory, and the corresponding motor and the electromagnetic valve are driven according to the action instruction, so that the action of the bed body is realized.
When the operation end loosens the keys, the first microprocessor scans to obtain that the keys are loosened, whether a key value exists in the last scanning is judged, if yes, the time and the last key value at the moment are stored in the first memory, no instruction is sent to the second microprocessor at the moment, the second microprocessor judges whether an instruction exists at the last time, the sensor value at the moment is read if the instruction exists, the time, the last instruction value and the angle value obtained by the sensor are stored in the second memory, and the action of the motor electromagnetic valve is stopped.
The first memory stores information of two times when the key is pressed and released, and the second memory stores information of two times of starting and ending actions. And judging whether the key value of the first memory record corresponds to the instruction value of the second memory record or not and whether the instruction value of the second memory record corresponds to the change of the angle twice or not, thereby obtaining whether the system has a fault or not.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
