Protective Sensor Solutions in Stereo Parking.

Due to the progress of science and technology, economic development, people's lives have been greatly improved, families with their own cars are increasing day by day, more and more people choose to drive their own car, the increase in the number of vehicles and the number of parking spaces in the parking lot is missing, so that people in the search for parking spaces to spend more time. In addition to this, the lack of personnel guidance or some kind of technological products in the parking lot, drivers do not drive regularly in the parking lot, making the traffic situation in the parking lot chaotic. This directly affects the blockage of the entrance and exit roads of the car park, and also indirectly affects the smoothness of the nearby traffic roads. Therefore, automatic three-dimensional parking equipment is more and more popular. Stereo parking system has always been known for its efficiency and safety. So how does it ensure the safety of vehicles and people? This is all thanks to the photoelectric sensor. Photoelectric sensors work on the principle of light refraction, energy-saving and environmentally friendly, and accurate detection. G-TEK Sensor has been in the sensor research and development and production industry for 20 years, independent research and development of photoelectric sensors, safety light curtains and laser radar by the customer's favorite.

1.LSE Area Detection Light Curtain
LSE area detection light curtains are usually used in three-dimensional circulating garages. When the vehicle enters the garage, a set of LSE area detection light curtains are installed on the left and right sides of the parking space. In order to detect the absence of other persons or objects in the area above the drop-off of the parking space when the garage is moving in a cycle. Ensuring that people leave the hazardous work area after parking, the device works properly.The LSE Area Detection Light Curtains have a slim profile for easy integration in any confined space. The length can be customized to suit large areas. In order to make the product more suitable for cubic parking applications, a metal impact resistant housing can be added to increase the shock absorption and impact resistance of the product.

LSE light curtain features:
（1）Slim profile for easy integration in any confined space.
（2）Simple installation with back and side channels.
（3）Shortest length up to 160mm.
（4）LSE-DB Door Light Curtain with Blanking Function
（5）IP65 grade protective shell design
（6）5/8m detection distance, suitable for industrial speed gates,stereoscopic parking equipments, logistics sorting lines and access gates.

2.PF50T photoelectric sensor for garage guardrail protection
Two lifting and panning three-dimensional garage is currently the most common three-dimensional parking equipment. In the lifting and traversing three-dimensional garage, in order to realize in the parking to take the car, effective isolation of personnel and machinery to ensure the safety of personnel purposes, the need to set up the front guardrail. So in order to make sure that there is no vehicle and personnel in the area where the guardrail falls, we need to install a pair of PF50T counter-reflective sensors on both sides of the area where the guardrail falls.The working principle of PF50T is that the emitted light must be received, so it can effectively reduce the problem of missed detection of highly reflective objects. This ensures a safer process.

The PF50T is also used as a guarding device for large garage doors in large automated parking structures.

PF50T Photoelectric Sensor Features:
1.Through beam type, 10m/18m/25m/50m detecting distance
2.High reliability, can work normally in harsh environments
3.Stable and reliable in a robust housing
4.Integral package, protection rating IP67

3.LMO LIDAR for automatic parking robot protection
AGV automatic parking robot is also one of the hot trends in the field of automatic parking nowadays. It automatically travels to the bottom of the vehicle, smoothly lifts the vehicle and then accurately delivers it to the access station. And according to the system of intelligent computing, combined with the vehicle volume and other data, the vehicle will be automatically transported to the most suitable location to optimize the parking space, the owner does not need to drive into the garage, the operation is completed by the robot. In order to ensure that the AGV robot in the process of movement to achieve precise determination of the route to avoid collision with obstacles. A small LiDAR is usually placed at the front and rear of the AGV robot, and the LMO LiDAR is compact and easy to integrate. LMO LIDAR is compact and easy to integrate. It has 270° wide-angle detection, eliminating the dead angle of detection. Provides a high level of safety protection.
LMO LIDAR Sensor Features:
(1) Small size 
Compact design , easy for installation 
Widely used in AGV, logistics, security and other fields.
(2)270° high wide-angle scanning
270° high wide-angle scanning, scanning range 6/10m optional
(3)Raw data output
Raw data output fo r secondary development
(4)Anti-crosstalk
No cross-talk among multiple laser scanners 
(5)Flexible
32 groups of defined detection areas with high flexibility .

4.GVD Vehicle Detector
Parking lot vehicle gate is mainly used as a detection of vehicles in and out of the charging system, but in order to prevent the vehicle in the process of passing the gate down to smash the car. Usually GVD vehicle detector will be installed in the ground below the vehicle gate. Mainly as a road gate vehicle anti-smash protection and car over the automatic drop detection.
GVD vehicle detector features:

1. Select the detection sensitivity and sensitivity bootstrap function through the dip switch
2. Suitable for high-speed toll booths, stationary overrun stations, material yards and other applications.
3. Support switching output
4. Support the working characteristics in rain, snow and foggy weather
5. Stable system, realizing all-weather 24-hour operation.

5.PF50R laser sensor for garage door protection equipment
One or three garage doors are usually placed on the lowest level of a three-dimensional parking building. In order to prevent the hard rolling doors from smashing cars and pedestrians. The PF50R-AR laser sensor has a built-in polarization design to effectively detect highly reflective objects. The working principle of mirror reflection, only one end needs to be connected to electricity. It is easy and quick to install and saves installation time.
PF50R-AR Photoelectric Sensor Features:: 
1. Ultra-long 8-meter detecting distance
2. Red laser positioning is a convenient, high precision
3. IP67-rated waterproof housing
4. Light/dark through the model selection
5. With short circuit protection and reverse polarity protection
