Multi-point disposed mobile detection wireless sensor system based on infrared ray

The invention relates to a multi-point disposed mobile detection wireless sensor system based on infrared ray in the wireless network technical field. The probe node is configured with a passive infrared sensor for detecting a mobile target and mounted a position where the mobile target is detected. When object different from background temperature passes through the probe area, the node reports the mobile object probed and identity ID of itself; the base station node is used for collecting information of each probe node transmitting by radio and transmits the information via serial ports/USBlines to a mobile detection information server; the mobile detection information server is communicated with the node via the serial ports and assembles mobile information of each probe node as well as cooperating with peripheral systems. The invention detects mobile object by the infrared sensor and collects mobile information via the wireless communication as well as assembles information via acentral computer to provide service for users.
