How does a optical turnstile work?
How does a optical turnstile work? The infrared sensors configured inside the optical turnstile gate play a crucial role.
Infrared sensors are usually infrared tubes with emission and reception functions. It consists of a transmitter, receiver, and filter.
The transmitter emits infrared light, and the receiver receives the reflected signal of the light. When pedestrians or objects enter the sensing range of the optical turnstile gate, the transmitter of the infrared sensor will emit a beam of infrared radiation. These infrared rays will be reflected back to the sensor receiver by pedestrians or objects. The receiver will convert the received signal into an electrical signal and filter it through a filter. Ultimately, the signal will be transmitted to the control circuit for processing.
Here is a detailed introduction:
When pedestrians or objects enter the sensing range of the gate, the infrared transmitter will emit a beam of infrared radiation.
These infrared rays will be reflected by objects or pedestrians and then received by the receiver. The receiver will convert the received signal into an electrical signal and transmit it to the control circuit.
In the control circuit, these signals are processed through amplification, identification, counting, and comparison, and ultimately converted into signals to control the opening and closing of the optical turnstile gate.
For some complex systems, additional calculations, protection, and self diagnosis operations may be required.
In the control circuit, an important part is the output circuit. It is responsible for converting the processed signal into the signal required for the optical turnstile gate control system, and controlling the opening and closing of the optical turnstile gate through the motor drive system.
In addition, the infrared sensing system of the gate also includes a targeted infrared sensor, which detects objects through an infrared beam between the transmitter and receiver. When an object passes through, it will block some or all of the light, causing the receiver to receive different signals and control the opening or closing of the optical turnstile gate.
