?ROSIM's parking guidance system ? ?????? ROSIM's parking system include?wireless parking space detector ,wireless router and wireless parking data collector;this system?monitors the occupancy of vehicles in indoor/outdoor/roadside parking lot, each parking space features a?wireless?parking space detector??which feeds back occupancy information to wireless router.Then ,router transmit the information to parking?data collector?,and??this collects real-time parking occupany information and stores data for statistical analysis?. This can then be uploaded to an online server for external access ?for car park owner information to improve the efficiency of the car park.?and?Parking utilization and enforcement efficiency are optimized. ?Wireless parking data collector ? ? ? ? Key feature: ? 1.Automatic data collection; ? 2.Biddirectional communication with all components; ? 3.Rs232/485, USB, Ethernet interface; ? 4.Net capacity is up to 500 sensors per data collector. ? 5.Radio Channel and network ID assignment Relative Product? ? ROSIM parking infomation detection system consists of many sensors,a certain number of routers and one data collector. Sensor can communicate to a certain router or directly connect to data collector .All the routers make up a mesh network, which provides each single router multiple communication paths to other nodes to ensure a robust self-healing network. the paking space occupation information is sensed by sensor, and transmitted directly or through one or more routers to data collector. ? ? ? what we deliver??? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??

FAQ ? ? ??? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 1.How to calculate the quantity of sensors and routers that needed for a parking lot? ???? Because our detection system is based on zigbee technology, the nodes, which are sensors or routers in our system, connecting to a coordinator, which is data collector, could be supported up to 500+. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? But in order to improve the robustness of the wireless network and the efficiency of the detection system, what we ? recommended is no more than 100 sensors and 10 routers are expected to be connected to one data collector. ? ? ? Each of the connection capacity is: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 1.one WPDC data collector connects up to 10 sensors and 10 routers directly. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? 2. one WR router connects up to 32 sensors and 5 other mesh routers. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 2.How to test the detection performance of WPSD? ??? ? ? ? ??? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? ROSIM employs multiple detection technologies to achieve an extreme high detection accuracy. It is recommended that test should be carried out through a actual vehicle in a parking lot. The office test is not recommended. ? ? ? Any further question ,welcome to contact Lucy Skype:Lucy Ma153 ????? ?? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
