Real-time monitoring of agricultural products cold-chain logistics and transport can effectively ensure the quality and safety of agricultural products, reducing logistics cost. This paper analyzes three functional architectures, including the agricultural application of mobile terminal data acquisition, logistics warning and mobile payment. The cold-chain logistics of mobile service application system process and module structure are designed on the basis of the hardware environment of mobile device and wireless network environment. The system can monitor and manage the process of storage and transportation of agricultural products cold-chain through the mobile terminal, improving the efficiency of logistics.
