Abstract
The invention discloses a communication adapter device for sensor network multiprotocol support. A multiprotocol communication adapter of the communication adapter device realizes the flexible arrangement of space positions of a plurality of sensors in a short distance communication range through a system structure formed by multiple sensors and a communication adapter. Data can be emitted through wired communication and low power consumption wireless communication. After a sensor module is used for emitting data to the communication adapter in a short distance in real time, the adapter uploads the data to a server. Due to the fact that the number of long-distance communication modules is reduced, the sensor module can be well controlled in size and cost. More importantly, the power consumption of the wireless sensor module can be reduced, so that the consecutive working time of the system can be prolonged. Moreover, needed communication protocols are stored in the adapter so as to support access of multiprotocol sensor modules and sending and receiving of server data.
