?Car Stacking System Sensor ? Product Description ? ? System Overview: ? ? ? The Detector is an important part of parking management system, which is installed in the bottom center of each parking space, collecting parking status data in real-time, at the same time the parking information were transmitted in a timely manner through the transmission of radio frequency wireless network to a reader. This parking information can be used to provide application service to people for car parking guidance system, and also can be used for parking management.? ? ? ? Reader is a device for smart parking space detector’s data reception, it’s through RF2.4G signal to connect to smart parking space detector, it sends effective data to control center immediately when it receives smart parking space detector’s data. the control center must return confirmation after receiving the information, otherwise the reader will put data stored locally, repeatedly sent, until success. The reader’s standard channel of communication is RS232/RS485, you can choose to buy WIFI/GPRS adaptor to connect reader to PC wirelessly. For cable, fiber channel, you can choose to buy the serial port server, the serial port to the network port, the optical fiber interface. System Components ?

Work on demands, LDSW uses Dsss technology, LDSW tag can work in different ways,?LDSW uses a patented technology “DNA check”, which allows a tag being woken up far?from 1500 m away and at very low power consumption. Many different frequency channels?can be used in the same LDSW working system, This would allow many readers working?at the same time. This technology also would speed up the working process, cut down tag?power consumption and obtain great working flexibility. ? >>>More About LDSW ?
