the door opening and closing sensor 401 is used for detecting the door state of the elevator car door; the working principle is as follows: when an object to be detected is above a sensor lens, the object reflects light emitted by a photoelectric switch emitter to a receiver, and then a photoelectric switch generates a switching signal; in practical application, an inner door of the lift car is an object to be sensed, when the inner door is closed, a centimeter right in front of the sensor can be shielded, and when the inner door is closed, the sensing distance of the sensor is not shielded; note that: 1. when the door is closed, the door is shielded in the sensing distance, and when the door is opened, the door is not shielded in the sensing distance; 2. the induction distance of the sensor is about 1 centimeter, different inductants are slightly different and can be judged according to an EOC indicator light of the equipment; 3. the normal work of the original elevator door motor cannot be influenced by the installation of the sensor.
The human detection sensor 402 is used to detect whether a person is in the elevator; the working principle is as follows: whether people exist in the elevator can be sensed through the heat release human body sensing switch; installation considerations: 1. the human body sensor is arranged at the top in the car; 2. the place where the human body sensor is arranged cannot be shielded by other objects; 3. the human body sensor can radiate all the elevator cars as far as possible; 4. because of the operating characteristic of sensor, the human body can trigger when removing, can cancel when the human body is static, and this sensor has the time delay function, can continuously trigger someone signal promptly to sensing someone, just can judge nobody after the time delay, and the time delay is generally 40S, if sense someone again in the time delay period and can delay with new time point.
The battery car identification camera 403 functions as follows: when the electric vehicle is pushed into the elevator car and the camera identifies the electric vehicle, the voice alarm gives out voice broadcast and plays voice for preventing the electric vehicle from entering. The working principle is as follows: the electric vehicle detection, analysis and identification are realized by adopting a machine vision image perception technology and an artificial intelligence deep learning technology, and an image model is established by an electric vehicle identification algorithm in a machine vision image scene to finish automatic detection and identification of the electric vehicle.

The floor sensor 105 is a U-shaped photoelectric floor sensor for detecting the running state (up, down, stop) of the elevator and the floor where the elevator is located; the principle is as follows: the leveling sensor integrates two groups of photoelectric correlation sensors and is used for detecting the ascending, descending and stopping states of the elevator, and the floor where the elevator is located judges whether the elevator ascends or descends according to the passing direction when the magnetic isolation plate of the elevator passes through the U-shaped sensor, and judges that the elevator stops when the two groups of photoelectric sensors are shielded. Installation considerations: the magnetic isolation plate can effectively shield the U-shaped sensor in the running process of the elevator; when the elevator is in a stop state, the magnetic isolation plate must be capable of shielding the two photoelectric sensors, otherwise the stop state cannot be judged; the mounting direction is consistent with the printing direction of the sensor, namely the character faces upwards.
Limit alarm sensor 106 functions: whether the elevator has a top-rushing or bottom-squatting fault in the running process is detected. The working principle is as follows: when the elevator normally operates, the highest position where the elevator car can ascend is called an upper flat layer, and the lowest position where the elevator car can descend is called a lower flat layer; when the elevator exceeds the upper flat layer or the lower flat layer, the top rushing or the bottom squating occurs when the elevator touches the limiting stopper. There will be magnetic induction between limit warning magnet and the limit sensor, can receive magnetic induction when limit sensor passes limit warning magnet, this shows to the elevator that towards the top or squat the end. Installation considerations: 1. the limit alarm magnet is not shielded by other objects. 2. The mounted limit sensor is not shielded by other objects. 3. When guaranteeing elevator normal operating, limit sensor can not pass limit warning magnet mounted position.
