一种遵循欧洲自动售货机协议的监控系统设计

Design of Vending Machine Monitor System Following EVA-DTS

目前我国自动售货机远程监控系统数据传输协议格式不统一,各个厂商的管理平台之间没有兼容性。针对这种现状,研究并设计一种基于EVA-DTS和GPRS的自动售货机监控系统方案。利用GPRS实现售货机与监控中心的组网,采用EVA-DTS建立数据的格式,设计并实现了实时的、安全度高的监控系统。该系统能够保障自动售货机与数据中心稳定的通信,便于运营者的运营和管理。任何符合EVA-DTS的售货机都可以用该系统进行管理,具有很强的通用性。

At present, the data transfer protocol of vending machine monitor system in our country is not unified. There is no compatibility in these management platforms developed by different vending machine factories. To tackle this problem, a vending machine monitor system based on EVA-DTS（European Vending Association Data Transfer Standard） and GPRS（General Packer Radio Service） is researched and designed. This paper completes the network construction between vending machines and data center by the use of GPRS, builds the data format of information by the use of EVA-DTS, and finally works out the monitor system which is real time and safe. The system ensures the steady communications between vending manchines and data center. It is easy to help managers run the machines and good in its compatibility. It can handle any vending machine which obeys the EVA-DTS.
