photoelectric sensor switch is used in parking
At present, with the development of technology, parking has a complete system, into the era of intelligent parking. Among them, in each big intelligent parking system, each kind of sensor’s application has provided the indispensable technical support for the intelligent parking.
Today, let’s take a look at the smart application of photoelectric sensor switch technology in parking lots.
Parking lot photoelectric sensor design, most of the vehicles used in the parking lot, parking space with or without vehicle sensing. If the parking lot’s intelligent system is a brain, the photoelectric sensors that power it is its neurons. As the car comes in and out, a series of sensor neurons respond, feeding back to the intelligent system’s brain, which makes the commands and the devices in the parking lot act accordingly. Next, let’s take a look at how the photoelectric sensor switch actually works. In the parking lot, most of the use of photoelectric sensors, which can be more effective detection of vehicles. The photoelectric sensor is installed at the gate. When the vehicle enters or leaves the gate, the sensor receives the “stimulus”, the sensor senses the vehicle according to the signal change of the reflected light, the “brain” system makes the instruction, the gate opens or closes.
Often, the number of parking spaces is displayed at the entrance or in the parking area, thanks to a photoelectric sensor switch installed in the parking space. When the vehicle enters the parking space, the same principle as the gate, sensor signals change, “brain” system according to the signal, issued instructions, display the number of parking spaces reduced. When the vehicle leaves the parking lot, the photoelectric sensor switch signal is restored, indicating that the parking space is empty. The “brain” system receives the information and outputs the information to the display screen. In practical applications, considering that sometimes someone will walk around and affect the accuracy of sensing the empty parking space, two photoelectric sensors will be installed in each parking space. When both are working at the same time, the parking space can be shown as empty, it’s error-proof. Because the parking lot environment has indoor and outdoor, in the application of the sensor, always hope that the characteristics of the sensor are not affected by the environment, temperature, also need to avoid mutual interference between sensors. Therefore, the stability of the sensor is one of the important criteria for the photoelectric sensor switch in the parking lot.
At present, in the market, sensor manufacturers of photoelectric sensor switch products have made a response to the relevant actual situation. For example, in a pair of photoelectric sensors, when one photoelectric sensor fails, it is not necessary to replace all but only one of them, and at the same time, multiple sensors can work even at very close range, and there’s no interference.
