Abstract:A design of cold?chain logistics intelligent sorting system based on RFID technology is proposed because the sorting effect of the traditional cold?chain logistics intelligent sorting system is bad. The hardware design of the system includes host module circuit, display module circuit, command module circuit, weight signal acquisition module circuit and cold?chain sorting device circuit. In the software of the system, the RFID technology is used to realize the intelligent sorting of cold?chain logistics. The design of cold?chain logistics intelligent sorting system based on RFID technology is completed by combining the software and hardware. After completing the establishment of the experimental environment, the connection mode of serial port of the hardware and software were debugged, and the sorting effects of the two systems were tested. The experimental results show that the cold?chain logistics intelligent sorting system based on RFID technology has better sorting effect and can meet the design requirements.

当前有关冷链物流智能分拣系统的研究较少,常采用的系统有基于模型的冷链物流智能分拣系统和传统的冷链物流智能分拣系统。这两个系统都是由计算机将到达的货物配送到指定地点,虽然具有较强的分拣能力,但是采用的物流设备都是以半机械化为主,劳动强度大,效率低,没有连续性[1]。现代的冷链物流智能分拣系统采用高效的自动化设备,配有AGV小车和自动上下料机器,具有节奏快和关系复杂的特点。基于上述冷链物流智能分拣系统存在的缺陷,提出基于无线射频识别技术的冷链物流智能分拣系统设计。……
