Aquatic product transportation monitoring system and method based on wireless sensor network

Abstract

The present invention provides an aquatic product transportation monitoring system and method based on a wireless sensor network. The system comprises the temperature sensor nodes installed on the logistics boxes in which the frozen aquatic products are put; an information aggregation node installed on the inner wall of a refrigerator car used for the aquatic product transportation; and a central controller installed in a scheduling center. The plurality of temperature sensor nodes are communicated via a Zigbee protocol, the temperature sensor nodes and the information aggregation node are communicated via the Zigbee protocol, and the central controller and the information aggregation node transmit the data via a GSM base station. The aquatic product transportation monitoring system based on the wireless sensor network of the present invention can monitor the temperature change of the logistics boxes real-timely during the transportation process of the frozen aquatic products and can monitor the working states of the temperature sensors real-timely, so that the aquatic product temperature change during the logistics transportation process can be acquired largely, and the refrigerated transportation of the frozen products can be finished better.

Description

technical field [0001] The invention belongs to the technical field of logistics monitoring, and in particular relates to a system and method for monitoring aquatic product transportation based on a wireless sensor network. Background technique [0002] As a special agricultural product, aquatic products are perishable and deteriorate during the circulation process. Therefore, they have certain requirements and deadlines for quality assurance and freshness preservation in the process of production, processing and final consumption, and are mainly transported in fresh or frozen form. [0003] Cold-chain logistics (cold-chain logistics) is based on refrigeration technology, using artificial refrigeration technology as a means, and connecting with production and circulation. It is a systematic project that fresh products are always in the specified low temperature environment in all links of production, storage, transportation, sales and consumption. [0004] Cold chain logist...

AI Technical Summary

Problems solved by technology

[0004] Cold chain logistics not only requires focusing on the minimization of the comprehensive cost of each logistics link, but also requires fast logistics and sensitive market response; while the logistics system is complex, with many participants and a high degree of information asymmetry; the quality monitoring of the logistics process is based on safety And real-time tracking requires a high degree of information technology support, and the traditional manual temperature collection method can no longer meet the needs
