| After the events "Fuyang milk powder" and "Sanlu milk powder", the people more and more attention to food safety of milk-maded products. The raw material is the key link of food safety, in order to effectively monitor milk tankers transportation process of enterprises'milk stand to prevent milk stands by the way to economic adding illegal source of food ingredients, this article study the milk source transport safety remote monitoring system.This article firstly introduced the background and significance of the subject, secondly detailed introduced a wireless remote data transmission GPRS principle, the global positioning GPS principle, Mapx activex technology's basic theory, and elaborated on the design for the terminal and monitoring centre of the milk source transport safety remote monitoring system.This article mainly discussed the database for monitoring centre, the importing of the monitoring terminal's collected data, the building of an application server's important functions, the various parts design of the client. the main works contain: builded the monitoring centre by using three-tier architecture development patterns based on the midas technology; according to the application purpose of this system software and the collected data of monitoring terminals, detailed designed the database of monitoring centre; using Object Pascal language programming the functions of the application server, carried out packing the client's business services and request services to the application server, provided business deals to client by the way of calling functions; using the object-oriented delphi development environment, builded the client visual interface to implement the management of monitoring information and milk stand information; using the powerful map-analysis-function activex technology mapx, realized the basic operation of the map and the tankers' electronic maps location; recovered pictures and displayed. |
