What's Solution

Solution

Gates & doors

Photoelectric sensors (photo sensor) are widely used in gate and door industry. Door sensors are mainly realized by means of microwave, infrared or laser detection. Infrared photoelectric sensors and infrared light curtains are most widely used in industrial doors such as high speed doors, roller shutter doors and sectional hard high speed doors. When the people or objects are detected by the infrared device (photocell or light curtain), no matter whether people move or not, as long as they are within the detecting range of sensors and light curtains, they will react and give the control output to protect people or objects from being pinched. Microwave radar is also a widely-used product in automatic door industry. It responds to the movement of people or objects, thus realizing the automatic door switch control.

Pedestrain turnstile gates

Turnstile is a kind of access management equipment to manage the flow of people and standardize pedestrian access which is widely used in office buildings, government agencies, airports, subway, high-speed rail, scenic spots, enterprises and other places. Photoelectric sensors is an important part of intelligent barrier system. Pedestrian barrier gates set a certain number of opposed type photocells at different positions inside the barrier gate and when people pass, the emitting light beams from the photocells are blocked by people and the Multiple detection points form an effective identification of the trajectory and behavior of the passers-by and drive the pedestrian channel gate wings. In addition, high-density infrared light curtain can be used in high-end barrier gates and proximity sensors can also be used in the gate control system. With 20 years of experience in the industry, G-TEK has been committed to providing the most comprehensive and reliable photoelectric sensor solutions for intelligent pedestrian access gates to solve all your problems.

Access control in automatic door industry, passageway, barrier gates for pedestrians and vehicles

Intelligent transportation

Tianjin G-TEK sensors for intelligent transportation solutions are mainly used to detect the vehicle's outer profile, drive shafts, and axles to identify the vehicle model and other inforation. It is used in smart toll collection, smart overload control, traffic investigation and related fields.

Smart parking

With the rapid development of economy and the increase of car ownership, parking difficulty has become a common problem. Compared with traditional parking spaces, three-dimensional garage has significant advantages in cost, air access utilization and other aspects, and has become the preferred alternative to the development of parking industry. Sensors are used for data acquisition of intelligent parking system, which can measure the length and height of the vehicle and select suitable parking space. By distance comparison, it can determine whether the vehicle has abnormal displacement in the process of parking, and avoid unnecessary collision or scratch.
