Elevator is a kind of vertical elevator powered by a motor, equipped with a box-shaped pod, used for multi-storey buildings to take people or carry goods. With the occurrence of multiple elevator accidents, people have higher and higher requirements for elevator safety. In order to prevent the recurrence of similar accidents, elevator designers have installed a variety of sensors and measuring instruments on the elevator body. Inclination sensors are one of them.
The tilt sensor is usually installed on the top of the elevator to detect the verticality of the elevator in real time. When the elevator tilts too much, the relevant personnel will understand the situation in real time and deal with it in time. The real-time angle signal output by the inclination sensor can also be displayed through related meters and can be networked to form a monitoring network, so as to better maintain the use of the elevator and ensure the safety of people entering and exiting. The more popular sensors used to prevent pinching in elevators are generally through-beam infrared photoelectric sensors
It is a device used on the door machine to protect people or things from being pinched. The infrared sensor
emits a beam of device to illuminate the transmitter or receiver installed on the other side of the elevator door. One side of the elevator door is equipped with an emitter and a receiver at the other. When the middle beam is blocked and the receiver cannot receive the emitted beam, the controller will respond to the elevator main board, and the elevator door will naturally open.
