TOWARDS A MULTI-SOURCE RECORD KEEPING SYSTEM FOR AGRICULTURAL PRODUCT TRACEABILITY
Agricultural production record keeping is the basis of traceability system.To resolve the problems including single method of information acquisition,weak ability of real-time monitoring and low credibility of history information in agricultural production process,the multi-source record keeping system was designed.The system consisted of the following components:Ⅰ) Sensing equipments.Based on ZigBee and video processing technology,the system could realize remote monitoring of crop temperature,relative humidity,light intensity,and dynamic process.Ⅱ) Transmission technology.The system supports transmission techniques of text,images,and video information using 3G module.Also the H.264-based video compression hardware platform and software architecture were built.Ⅲ) Server.The environmental and compressed video information was eventually transmitted to the server for agricultural product traceability.The whole system was tested in the greenhouses.Tested results showed that the multi-source record keeping system had the ability of accurate acquisition and smooth transmission,and provided strong support for traceability system.
