Wireless information acquisition system and method based on ZigBee and public transport vehicles

Abstract

The invention provides a wireless information acquisition system and method based on ZigBee and public transport vehicles. The system comprises ZigBee vehicle-mounted terminal equipment, a ZigBee network coordinator and ZigBee detection node terminal equipment, in the running and operating process of the ground public transport vehicle, ZigBee terminal devices of all road surface detection nodes such as garbage cans, well lids, sewers and street lamps can report state data of the ZigBee terminal devices to vehicle-mounted ZigBee terminal devices on passing vehicles at any time through a ZigBeenetwork. And after data is received, the vehicle-mounted ZigBee terminal devices pack the data and transmit the data back to the control center. And the control center sends the data to a related unit department for further analysis and application according to the node type represented by the data packet, so that mobile acquisition and comprehensive analysis of mass data are realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for collecting wireless information based on ZigBee and public transport vehicles. Background technique [0002] At present, the application based on the Internet of Things has become increasingly in-depth. Remarkable results have been achieved in various fields and industries. With the rapid improvement of the application level of information technology, wireless city, as the infrastructure of urban informatization and modernization, has become an important yardstick to measure the comprehensive competitiveness of a city. [0003] For example, a large number of Internet of Things applications such as urban sewer environment monitoring and management, underground pipe network manhole cover management, street lamp management, and garbage bin management can greatly protect people's daily life. But how to collect data in these application scenarios, the gen...

Problems solved by technology

But how to collect data in these application scenarios, the general way is that each application node uploads data through GPRS / 3G, etc., because it involves the payment of communication fees, when a large number of sensors need to report data, the communication fees generated are extremely high , which also led to the development of the Internet of Things not being able to effectively cater to the development trend of the wireless city

[0004] Wireless sensor network technologies such as WIFI and Bluetooth have problems such as short service life of the network, high redundancy of collected data, and large deployment of short-distance communication network infrastructure, and require other remote network devices as access points. To report the data of the node to the remote end
