Domestic ZigBee research started relatively late. Domestic ZigBee module manufacturers are generally limited by the number of chip manufacturers and other price restrictions. The domestic market is mainly occupied by foreign instruments. There are no mature self-developed ZigBee products in China. There are only some research and simple applications. of articles appeared in the journal magazine

The invention discloses a ZigBee-based 3D intelligent visualized real-time traffic monitoring system, which comprises an urban traffic information module, a ZigBee network module and a 3D urban map module, wherein the urban traffic information module comprises transport means information, traffic sign information and traffic light information; the ZigBee network module comprises ZigBee network mobile nodes and ZigBee network fixed nodes; the transport means information is transmitted to the 3D urban map module sequentially via the ZigBee network mobile nodes and the ZigBee network fixed nodes; the traffic sign information is arranged in the 3D urban map module in advance, and the traffic light information is transmitted to the 3D urban map module via the ZigBee network fixed nodes; and the received transport means information, the traffic sign information and the traffic light information are analyzed and compared in the 3D urban map module. The ZigBee technology is applied to information transmission of a traffic detection system, real-time display via the 3D urban map is carried out, and the system has the advantages of high efficiency and high accuracy.
Description
technical field [0001] The invention relates to a real-time visualized traffic monitoring system of a traffic system, in particular to a real-time visualized traffic detection system utilizing ZigBee networking technology combined with a 3D city map and an original traffic system. Background technique [0002] Most of the monitoring methods of the existing traffic monitoring system are to extract images through the cameras installed on the traffic routes, transmit the image data of this plane to the control center, and judge various traffic conditions manually. This judgment method consumes A lot of manpower, low efficiency, low accuracy. In addition, the communication methods adopted by the existing traffic monitoring system are relatively backward. [0003] With the continuous development of wireless communication technology, ZigBee technology wireless communication has sprung up, including wireless local area (WLAN), Bluetooth (Blue.Tooth) technology, wireless fidelity (...
