Detection Device: Containing smart-detection sensors, including an ultrasonic sensor (for detecting
motor running and reversing), pressure sensor (for detecting occlusion). Detect corresponding
signals, which after being amplified and transferred to microcomputer system for signal processing,
automatic detection and operation is triggered.
Alarm System: Signals that are detected by the sensor, after being processed by the microcomputer,
trigger alarm control signals. At the response of the unit’s alarm system, operator is notified. Alarm is
composed of 2 parts, including photoelectric alarm (light emitting diode) and audible alarm
