Traditional UHF RFID gateway is inevitable due to a variety of data in the process of a gateway competition at the same time, the conflict will cause the gateway failed, which reduces the environmental monitoring information acquisition accuracy. To this end, was designed and implemented based on the multi-channel MC13213 distributed environmental monitoring system of UHF RFID gateway system. Hardware part elaborated based on the RFID MC13213 gateway design methods, emphasis on the gateway terminal nodes, gateway routing nodes and gateway nodes at the centre of the design method. Software part in detail in this paper, the design of the communication mechanism between gateways process mechanism and gateway task data structure programming method. The experimental results show that the system presented in this paper can avoid the ultra high frequency RFID gateway in the conflict in the process of communication, improve the accuracy of environmental information collection
