摘 要：食品安全是當(dāng)前我國(guó)面臨的重要社會(huì)問題之一，引起社會(huì)的廣泛關(guān)注。目前國(guó)內(nèi)以保障食品質(zhì)量安全為目標(biāo)的應(yīng)用系統(tǒng)（如豬/牛肉、酒類、牛奶等的溯源系統(tǒng)）已經(jīng)很多，但是在使用便捷性、系統(tǒng)兼容性、系統(tǒng)可擴(kuò)展性等方面存在不足之處，并且應(yīng)用推廣的成本有待進(jìn)一步降低。該課題致力于突破農(nóng)業(yè)物聯(lián)網(wǎng)的關(guān)鍵技術(shù)，基于開環(huán)的網(wǎng)絡(luò)數(shù)據(jù)庫(kù)，建立開放的、標(biāo)準(zhǔn)化的、數(shù)據(jù)可信的應(yīng)用服務(wù)支撐平臺(tái)，為企業(yè)用戶、監(jiān)管用戶和消費(fèi)者提供可信的數(shù)據(jù)服務(wù)。所述的關(guān)鍵技術(shù)包含3個(gè)方面：感知層關(guān)鍵技術(shù)，網(wǎng)絡(luò)層關(guān)鍵技術(shù)和應(yīng)用服務(wù)層關(guān)鍵技術(shù)。在感知層關(guān)鍵技術(shù)方面主要研究了基于射頻識(shí)別（RFID）的大容量電子標(biāo)簽和溫濕度傳感器標(biāo)簽、無(wú)線土壤溫濕度傳感器、通用傳感器接口電路等；在網(wǎng)絡(luò)層關(guān)鍵技術(shù)方面主要研究了基于OPENNET的農(nóng)業(yè)物聯(lián)網(wǎng)仿真平臺(tái)、用于農(nóng)產(chǎn)品流通環(huán)節(jié)的無(wú)線傳感器網(wǎng)絡(luò)技術(shù)等；在應(yīng)用服務(wù)層關(guān)鍵技術(shù)中主要研究了農(nóng)業(yè)物聯(lián)網(wǎng)編碼、對(duì)象名解析服務(wù)、可信的電子履歷、食品安全數(shù)據(jù)挖掘、海量多媒體數(shù)據(jù)處理等內(nèi)容。課題研發(fā)的關(guān)鍵技術(shù)可以實(shí)現(xiàn)農(nóng)產(chǎn)品產(chǎn)地環(huán)境信息、流通信息和貯存信息的全程信息記錄，并通過(guò)溯源機(jī)或者智能手機(jī)提供給用戶查詢。與傳統(tǒng)的食品安全應(yīng)用系統(tǒng)不同，該系統(tǒng)采用標(biāo)準(zhǔn)化的編碼、基于Internet網(wǎng)絡(luò)提供開放的、標(biāo)準(zhǔn)化的應(yīng)用服務(wù)接口，通過(guò)與移動(dòng)互聯(lián)網(wǎng)的結(jié)合在智能手持終端上方便地向用戶展示所需的食品安全信息，并且結(jié)合群智的思想提供食品安全評(píng)價(jià)信息。該課題的研究成果在江蘇無(wú)錫、浙江嘉興、山東濱州等地進(jìn)行了示范驗(yàn)證，并且取得了積極的應(yīng)用效果。

Abstract：Food safety is a big social problem in China right now and is causing wide social attention. There are already many applications and systems aiming for food safety in China， such as tracking and tracing system for swine/buel industry， liquor， milk， etc.， but the convenience， compatibility， and extensibility are to be improved， and the cost is needed to be lowered as much as possible. This project is aiming to break through the key technologies， to build an open， standardized， credible application service platform based on the open-loop networked database， and to provide data service for the stake-hoders， government supervisors， and the end users. The key technologies covered the 3 layers of Internet of Things （IoT）： sensing layer， network layer， and application/service layer. In the sensing layer， we did research on large-memory radio frequency identification （RFID） tag， temperature/humidity sensor tag， and general sensor interface； in the network layer， we did research on simulator of agriculture IoT based on OMNet platform， wireless sensor network （WSN） for field monitoring and transportation monitoring； in the application/service layer， we did research on the coding schemes， object name service， credibleE-pedigree， mass data mining for food safety， and multi-media data processing， etc. Based on the key technologies developed in this project， the environment information of the farms and the states of the food during transportation and storage can be audited， and be ready for the end users to check through a stand-alone machine in the market or through the smart phone using an app developed in this project. Different from the traditional food safety systems， the system in this project adopted standardized coding scheme， open and standardized application service interface based on the Internet， and combined the mobile Internet to conveniently provide the necessary information of food safety to the consumers. Furthermore， the end users using the crowd-wisdoms can make evaluations. The research results of the pilot projects have been implemented in Wuxi City， Jiangsu Province，Jiaxing City Zhejiang Province， Binzhou City Shangdong Province， and achieved positive feedbacks.

Key Words：Food safety；Agreculture Internet-of-Things；Code interpreter；E-pedigree
