When the flow of people is large, the tripod turnstile gate with safety photoelectric sensor can be selected to improve the safety performance of the gate. At present, many tripod turnstile gates are using infrared photoelectric sensors and proximity sensors, which play an important role in the normal operation of tripod turnstile gates. However, because infrared photoelectric sensors are prone to external environmental interference and signal instability or sensitivity reduction, it is necessary to screen them when selecting infrared photoelectric sensors. This paper describes how to select the safety photoelectric sensor suitable for the application of the tripod turnstile gate to ensure the normal operation of the tripod turnstile gate.

The role of safety photoelectric sensor in tripod turnstile gate
tripod turnstile gate, as the name suggests, is a kind of channel management equipment composed of three rollers, which is widely used in intelligent buildings, sports stadiums, exhibition halls, airport stations and other crowded places, for pedestrian management, control and guidance, the direction of pedestrian traffic and lock the direction of the gate, effectively control the pedestrian density of the pedestrian channel. In the tripod turnstile gate system, the safety photoelectric sensor plays a very important role. In the application process of tripod turnstile gate, there are often some unexpected situations, such as excessive human flow or brake failure. This is where safety photoelectric sensors come into play.
The safety photoelectric sensor of the tripod turnstile gate uses an infrared transmitting and receiving circuit. When a pedestrian passes through, the infrared transmitting and receiving circuit will generate a pulse signal, which will cause the output signal of the safety photoelectric sensor to change. If the passing pedestrian does not pass through the gate or the gate fault causes the infrared transmitting and receiving circuit to work abnormally, the safety photoelectric sensor will output a pulse signal unrelated to the number of pedestrians.

How to choose the right safety sensor:

Working principle: The sensor of the tripod turnstile gate can use a variety of working principles, such as proximity sensor, infrared sensor, ultrasonic sensor, microwave sensor, etc. Choose the right working principle according to the actual needs.
Detection distance: The detection distance of the sensor should be able to meet the actual use needs of the tripod turnstile gate. Select the appropriate detection distance according to the size and installation position of the tripod turnstile gate.
Accuracy requirements: Determine the accuracy requirements of the sensor according to the use scenario of the tripod turnstile gate. Some scenarios may require higher accuracy, while others may tolerate a certain amount of error.
Protection level: Outdoor environments usually have higher humidity, temperature, dust and other factors, so it is necessary to choose a diffuse photoelectric sensor with sufficient protection level. In general, protection levels of IP65 and above can meet the requirements of outdoor use.

Operating temperature range: The outdoor environment temperature varies greatly, so choose a diffuse reflection photoelectric sensor with a wide operating temperature range. Ensure that the sensor can work properly in outdoor high and low temperature conditions.
Anti-interference ability: there may be interference sources in the outdoor environment, such as sunlight, rain, wind, etc. The choice of diffuse reflection photoelectric sensor with better anti-interference ability can reduce the situation of false triggering and misjudgment.
Detection distance and Angle: Select the detection distance and Angle of the diffuse reflection photoelectric sensor according to the actual needs. Ensure that the sensor can cover the effective detection area of the tripod turnstile gate.
Reliability and durability: Select diffuse reflective photoelectric sensors with good reliability and durability to cope with long-term use in outdoor environments. You can refer to the manufacturer's product quality and reputation.
Cost: According to budget constraints, select the appropriate diffuse reflection photoelectric sensor. Balance price and performance, choose the sensor with high cost performance.
