Construction Of Chinese-sensible Code Engine And Its Application On Fishery Products Quality Traceability System

The automatic identification technology of barcode as data carrier can realize the synchronization of both logistic distribution and information flow effectively and solve the key technology of the agricultural products' quality traceability system. To decrease the cost of traceability system and increase the capacity of information, we have proposed a universal alignment pattern method based on the Chinese-sensible code and QR code, improved an algorithm of sampling grid above the 4th version, broke through the optimization of the key technologies, such as mixed encoding, RS error conecting and midpoint extracting of detection pattern, and in the end, set up a Chinese-sensible code encoding and decoding engine.The fishery products quality traceability system of multi-level and multi-hierarchy role access control was designed and implemented from analyzing the flow of fishery products. Information interactive platform was provided for the producer, quarantine inspector, supervisor and consumer, through which providing traceability services, certification and supervision services and preventing falsity services by telephone, internet and short message.
