To multiple sensors and unifications tube and sensors server via the communication network is Wireless sensor network system, wherein the environment server first to get the sensor the surplus driving time of battery, and the target surplus driving time. Then, controlling the motion environment, and sensors the surplus driving time and target surplus driving of the battery is approximately same. The automatic, can reduce the system superintendent's and burden, and sensor burden of battery charging processing.
