【摘要】：充电设备的安全功能检测可以保障人身和财产安全，也是判断设备实用性和可靠性的重要因素之一，其检测目的在日常生活中有着重要的意义。本文首先从充电设备的安全功能概念和主要检测方法出发，着重叙述了充电设备的过流检测、漏电检测和连接状态检测原理，并确定了系统设计难点：对于互感器采集的信号进行放大处理和各采集模块的误差分析。然后简要介绍了基于单片机的嵌入式系统设计方法及流程。通过对不同电路设计方案的分析和比较，结合嵌入式系统设计理念，最终提出了一种以PIC单片机为核心的数字式充电设备安全功能检测系统。硬件方面，文中依据功能划分详细论述了组成安全功能检测系统的各个模块，特别是过流检测和漏电检测这两个关键部分。软件方面，给出了系统软件流程图，结合硬件开发了各功能模块驱动代码，重点讨论了AD检测和PWM产生的代码编写。最后，设计了印制电路板并装配成整机，对设计的检测系统进行了分模块调试和整机测试，并提出了系统改进意见。结果表明，该系统大大提高了数据处理能力和测试精度、操作简便、测试周期短、效率高、稳定性好、具有较高的实用价值和推广前景。
[Abstract]:Security function of charging equipment can guarantee the personal and property safety, is one of the important factors to judge the equipment reliability and practicability, the detection in daily life has important significance. This paper from the charging equipment safety function concept and main detection method of the described overcurrent detection charging equipment, leakage detection and connection status detection principle, and determine the design difficulties of the system: for a signal transformer acquisition error was amplified and the acquisition module analysis. Then briefly introduces the design method and process of embedded system based on MCU. Through analysis and comparison of different circuit design, combined with the embedded system design concept, finally put forward a digital PIC microcontroller as the core of the charging equipment safety function detection system.
The hardware aspect, based on the function module detailed safety function detection system, especially the flow of the two key part of the detection and leakage detection. In the software, the system software flow chart is given, with the development of hardware modules driver code, discusses the detection of AD and PWM production code. Finally, the design of the printed circuit board and assembly machine, the detection system was designed and debugged and the test system, and some suggestions are put forward. The results show that this system can greatly improve the ability of data processing and test precision, simple operation, short test period, high efficiency and good stability. It has high practical value and promotion prospects.
