Abstract: Abstract: In order to realize automatic collection, transmission and storage of data in the process of agricultural product and food production, and embody them in the whole traceability process, this paper takes the broiler as an example, and a self-developed production environment supervision and monitoring control system is made, including environment collecting terminal, environment controller, embedded repeater and supervision and control server. Sensors of temperature, humidity, lighting and ammonia are integrated in the environment collecting terminal. Environment controller can control the draught fan rotation speed, ventilation direction, lighting, humidifier and heater. Embedded repeater can adopt the way of RS232, RS485, USB (universal serial bus), Ethernet, 3G/4G, Wi-Fi, ZigBee flexibly according to requirements. Automatically on-site, remote monitoring and early-warning system of production environment of broiler is implemented, and it is integrated into broiler traceability and supervision platform, which includes 3 sub-platforms i.e. enterprise management, government management and traceability sub-platforms. The platform adopts the method combining B/S (browser/server) and C/S (client/server) architecture. B/S architecture platform adopts Microsoft C#. NET language and is developed on ASP.NET framework. Database Sever adopts SQL (Structured Query Language) Server2014, with IIS7 as Web server. With RFID (Radio Frequency Identification) tag as carrier, it realizes information transmission and personnel quick login. All sorts of enterprises and users of different types have different authorities. All information including feeding stuff, drug, vaccine, death rate and elimination number for broiler, slaughtering, processing, storage and sales is recorded in the whole process of monitoring and supervision. Government participates in the whole process of broiler production. When the enterprise reports the marketing rate of broiler, and the broiler production is sold, quarantine will be done. Irregular sampling inspection can also be done. Multidimensional statistics that include query and export of information of the number of broilers for sale, broiler on hand and retail point and other special conditions are implemented. C/S architecture mainly solves the problem of being difficult in accessing internet. Wechat traceability is developed by using Java Web combined with Wechat public platform developer API (application program interface), with the database connected by the way of table view, which takes Tomcat as Web server. The broiler traceability and supervision platform based on Internet of Things is applied to 189 enterprises in Tianjin. It makes enterprise labor cost reduce by 50%, and profit increase by 34.09 million yuan every year. About 1 600 households newly added engage in broiler breeding now, and every household's income increases by about 9 000 yuan every year. The broiler traceability and supervision platform based on Internet of Things gives consideration to the interest of the enterprises, governments and consumers, and can be extended to the tracing and supervision of other agricultural products and food.
