Saiying No. 3

Haifeng saiying No. 3 automatic expansion door is made of high-strength aluminum alloy by one-time casting! 58x51mm special-shaped main material is bright red, and it is made of electrophoresis silver white 38x25mm three rows of net flowers. Its structure is strong and undoubted! The wheel center distance is 720mm, and the total width is 790mm. Red and silver saiying No. 3 is more intriguing!

The acoustic limit and anti climbing detection device of the electric retractable door measures the opening and closing length of the automatic retractable door and the infrared limit position length of the automatic retractable door using the acoustic ranging principle, and the output control is sent to the main controller MCU. When the main single chip microcomputer detects that the door has been opened and closed in place, it controls the automatic expansion door motor to stop running. When it is detected that the infrared limit is removed, resulting in the failure of the infrared anti-collision function,

The electric expansion door can be opened and closed within the set range. After closing the limit position, the conventional transmission of the electric expansion door is used as the radiation source of anti climbing induction. When it is detected that it is blocked by an obstacle, it is considered that someone or an obstacle climbs on the expansion door and makes a sound, so as to realize anti climbing.
