摘要:蓄电池作为直流备用电源,对系统的安全可靠运行有非常重要的作用。为避免蓄电池在长期使用中因质量问题出现故障而引发事故带来经济损失,需对蓄电池进行实时在线监测。

   本设计主要是基于CAN总线的对蓄电池状态进行检测设备的设计,通过ADC0832这一A/D转换设备采集状态数值,通过LCD1602显示出数值,并在电压较低的时候显示警报。此设计完成了A/D转换电路的设计,单片机控制电路的设计,LCD1602显示电路的设计,并且完成了CAN总线部分的硬件设计。完成了A/D转换部分、单片机控制部分、LCD显示部分的软件程序编写与这些部分的系统调试,在CAN总线部分完成了硬件制作。实现了对大部分蓄电池的电压数值实时显示的功能,运用电子技术长时间检测蓄电池的电压水平,省去了人工检测的工作并且能够在电压值较低时,提供警示显示。

Abstract:Battery as dc standby power, and the safe and reliable operation of the system is a very important role.To avoid battery in use for a long time because of quality problems have problems and cause accidents bring economic loss, accumulator must to on-line monitoring.

   This paper is designed to detect the battery status of equipment design based on CAN bus, through the ADC0832 A/D conversion equipment acquisition battery state of the numerical, through the LCD1602 showed numerical value and in low voltage when display alerts.This design completed the A/D converter circuit design, the design of the single chip microcomputer control circuit, LCD1602 display circuit design, and completed the CAN bus part of the hardware design.Completed the A/D conversion parts and single-chip microcomputer control part, LCD display part of the software programming in these parts of the system commissioning, in the CAN bus part completed the hardware production.Realize the most storage battery voltage values real-time display function, the use of electronic technology long time test battery voltage level, tell the artificial detection and be able to work in voltage value is lower, that provide warning.
