BIT监测系统的设计与实现

摘要

随着电子信息与自动化的蓬勃发展，由于电子设备的复杂程度是与日俱增，所以随之而来的是对于电子信息自动化设备的监测系统的出现。BIT测试技术就是系统性的针对设备可靠性安全性所诞生的测试技术。

本课题主要说明了使用STM32芯片制造的简易BIT监测系统。该BIT监测系统主要实现了对于设备的电流电压，温度湿度，上电次数的收集与记录。并实现断电后对于数据的存储功能。用于对设备的故障监测，状态监控，数据采集以及辅助维修。

首先对于BIT监测系统进行硬件构建，对于拟实现的功能进行硬件选择，进而实现PCB电路的设计，并进行PCB电路焊接实现硬件平台搭建。

其次对于BIT检测系统硬件所对应的软件进行开发。由于本课题采用STM32平台，所以主要是使用C语言在开发。

再次对BIT检测系统所搭建的硬件平台进行软件写入并测试，对于功能实现进行调整测试。对于出现问题的调整改正。以及对于本课题的分析总结

Abstract

With the vigorous development of electronic information and automation, the complexity of electronic equipment is increasing day by day.So the emergence of monitoring system for electronic information automation equipment follows. BIT testing technology is a systematic testing technology for reliability and safety of equipment.

This topic mainly explains the simple BIT monitoring system made of STM32 chip.The BIT monitoring system mainly realizes the collection and recording of current, voltage, temperature, humidity and power-on times of equipment. The storage function of data after power failure is realized. Used for fault monitoring, condition monitoring, data acquisition and auxiliary maintenance of equipment

Firstly, the hardware of BIT monitoring system is constructed. Select the hardware of the function to be realized, and then realize the design of PCB circuit. The hardware platform of PCB circuit welding is built.

Secondly, the software corresponding to the hardware of BIT detection system is developed. Because this topic uses STM32 platform, it is mainly developed with C language.

The hardware platform of BIT detection system is written and tested again. Adjust and test the function implementation .djustment and correction of problems. And the analysis and summary of this topic

Key words:BIT Monitoring System；STM32 chip；PCB design
