ZigBee-Based Wireless Monitoring System for Urban Waste Disposal Line
Client A system integrator in Beijing
Market demand
With the process of urbanization in our country, the output of municipal waste is increasing rapidly, and the composition of municipal waste is also becoming more and more complex. and industrialization. However, in the process of garbage disposal, the garbage itself contains a lot of harmful gases and germs. It is strongly required to improve the efficiency of garbage disposal, reduce manual on-site operations, and make the garbage disposal industry informatized and automated. The wireless monitoring system for waste disposal lines was successfully applied to a waste disposal site in Beijing and was recognized by customers.
solution
The general process of municipal waste treatment is screening, classification, oil furnace combustion, high temperature and high pressure catalysis, screening, mincing, drying, etc., and finally turning municipal waste into organic fertilizer. The whole control system adopts IP-Link2220 ZigBee wireless data transmission terminal to connect PLC to control the equipment of the assembly line, adopts IP-Link2220 self-organized wireless mesh network as data transmission medium, full-duplex data transmission and reception, system terminal collects data through ZigBee wireless mesh The network is uploaded to the central end, and the central end also sends commands to the PLC through the ZigBee wireless mesh network to control the device wirelessly.
IP-Link2220 data transmission terminal has built-in CSMA/CA anti-collision mechanism, which will not cause data loss due to too many data request points; adopts DSSS spread spectrum technology to flexibly select 16 communication channels; with routing function, the entire network supports up to 65535 nodes , greatly expand the network coverage area; the entire communication network is wireless, and there is no communication fee.
