Patent ID: 7593752

Claim:
A sensor network system, comprising: a sensor node comprising a first sensor configured to detect at least one of data of a temperature, acceleration, and illuminance, a first CPU for receiving first data which is at least one of data of a temperature, acceleration, and illuminance detected by the first sensor, a first memory in which software executed by the CPU is installed, a first wireless communication module for transmitting the first data obtained by the first sensor, and a first interface controller; and a base station comprising a second wireless communication module for receiving the first data transmitted from the first wireless communication module of the sensor node, a second memory for storing the data to be transmitted to the sensor node, a second CPU for controlling the data stored in the second memory to be transmitted to the sensor node, a second sensor configured to detect at least one of data of a temperature, acceleration, and illuminance, and a second interface controller, wherein the first sensor, the first CPU, the first memory, the first wireless communication module and the first interface controller are connected through a first bus, and the second sensor, the second CPU, the second memory, the second wireless communication module and the second interface controller are connected through a second bus, wherein the base station has a third memory which is connected through an interface to the second memory and stores commands to be transmitted to the sensor node, the second memory stores a portion of the commands stored in the third memory, and when the base station receives the first data from the sensor node, if the command to be transmitted to the sensor node is stored in the second memory, the command stored in the second memory is transmitted to the sensor node.
