Sensor network-based method, device and system for acquiring traffic state

The invention discloses a sensor network-based method, device and system for acquiring a traffic state, which relate to the field of intelligent traffic and are invented to solve the technical problem that a network for acquiring traffic state information cannot access a sensor with a wireless communication interface in the prior art. The sensor network-based method for acquiring the traffic state comprises the following steps of: 1, receiving traffic state information transmitted by a wireless sensor in a wireless mode; and 2, transmitting the traffic state information to a traffic management terminal. The method, the device and the system can be used for acquiring traffic information in the field of intelligent traffic.
