Then, the temperature of the external load is detected by the temperature detection unit 4 and fed back to the control unit 7, the control unit 7 reads the judgment logic of the preset temperature range, and according to the normal temperature value of the human body, the temperature t is supposed to meet the requirement
When the feedback temperature is less than 35 degrees or more than 37.5 degrees, the system is in an original state, the interference of large objects (objects within a preset weight range) can be effectively avoided in the process, meanwhile, the operation of the operators 5 with abnormal body temperature is prevented, and the man-machine safety is ensured. When the temperature of the feedback satisfies the above temperature rangeI.e. the external load is determined as a healthy operator who meets the working conditions, the control unit 7 transmits a control signal to the execution unit 8 so that the control system is started, and then the operator 5 performs the working through the upper control box 3.
In this embodiment, the distance detection unit 9 operates in real time throughout the operation and feeds back distance information to the control unit 7 if the distance is present during the operation
When the distance L meets the requirement again, the operator 5 is judged to be in the extrusion state, the control unit 7 transmits a control signal to control the pedal switch 11 to be invalid, the circuit is in the open circuit state, the aerial work platform cannot be controlled but cannot be stopped (is in the starting state), and when the distance L meets the requirement again
When the high-altitude operation platform is in the safe operation state, the operator 5 is judged to be in the safe operation state, the control unit 7 transmits a control signal to control the foot switch 11 to take effect, the circuit is in the power-on state, the high-altitude operation platform can be operated, the operator can be effectively prevented from being extruded in the process, and personal safety is guaranteed. But if the detected distance is
If the operator 5 is determined to be in a non-operation state, the control unit 7 transmits a control signal to control the pedal switch 11 to be invalid, the line is in a circuit-breaking state, the aerial work platform cannot be operated, meanwhile, the control unit 7 activates the load weighing unit 2 and the temperature detection unit 4 to perform data detection, when any detected data does not meet the judgment logic, the operator 5 is determined to leave the operation platform 1, and the control unit 7 transmits a control signal to the execution unit 8, so that the control system stops (i.e., the aerial work platform is controlled to stop).
