EDA地铁自动售票机机柜内部设备状态监控模块设计
本篇论文结合理论研究以及实际的需要，设计出一套能够实时监控机柜内状态的监控模块。本模块需要具有较高的可靠性，以及具有较好的扩展性。采用EDA的方法，设计出一个具有16路开关状态量输入通路，16路开关控制量输出通路，以及温度监控部分。16路开关状态量输入通道主要通过电平转换，RC滤波，过电压保护，反电压保护，光电隔离等技术。16路开关控制量输出通道，使用三极管驱动电路作为驱动。温度采集部分使用DS18B20芯片进行温度采集。软件部分，主要使用定时器0中断，串口通讯中断，完成相关功能。在串口通信方面使用MSComm控件进行串口通信。使用delphi软件完成设计,运用PASCAL语言进行编程。通过该监控模块可以实时监控机柜内的温度，机柜门的开合状态，以及钱箱，票箱是否被非法打开，保证财产的安全。

Title Kiosk enclosure internal device status monitoring module design
Abstract
Subway ticket vending machine is for passenger self-catering equipment. Its appearance greatly facilitate the people's daily travel. However,self-service subway ticket machines also exists security problems in many areas, such as security equipment, the Corporation's financial security issues, of passengers personal information security issues. So if real-time monitoring of the situation inside the cabinet, you can ensure reliable operation subway ticket vending machines, as well as people's daily life more convenient.
This paper combine theory and practical needs, design a set of real-time monitoring of the cabinet status monitoring module. This module is required to have high reliability, and has better scalability. The method using EDA design a state with 16-way switch input channels, 16 channel switch control output, as well as temperature monitoring section. 16 input channels switching state level, mainly through conversion, RC filter, over-voltage protection, reverse voltage protection, optical isolation technology. 16 output channels switch control, use transistor drive circuit as a driver. Temperature acquisition section uses DS18B20 chip temperature acquisition. The software part, the main use of the timer 0 interrupt, serial communication interruptions, the related functions. Use the MSComm control in serial communications for serial communications. Use delphi software to complete design, using PASCAL language programming. Through the monitoring module can monitor real-time temperature inside the cabinet, the cabinet doors open and close state, as well as the cash box, the ballot box is being opened illegally, ensure the safety of property.
