【摘要】：锌锰电池是电子设备常用的直流电源,其性能的好坏决定了电子设备的使用寿命,因此在电池流向市场之前要对电池的性能进行检测分析。目前,国内对锌锰电池的检测设备很多还是传统的、半自动化形式的仪表,需人工进行测量及记录数据,并且大部分仪表的功能比较单一,要进行电池的多个电性能参数测试时,需用多个仪表,这造成了人力物力的极大浪费。因此,设计出一套能够针对不同型号的锌锰电池进行多参数集中测试的自动测试系统具有工业应用价值和实际意义。本文结合锌锰电池检测设备的现状以及锌锰电池的测试需求,开发了基于可编程序控制器(PLC)和计算机共同控制的锌锰电池多参数自动测试系统。其中,以CP1H-XA型PLC作为下位机实现系统的运动控制和电池参数的检测,以普通PC机作为上位机实现系统的人机交互。首先,本文根据当前的电池参数检测技术,提出了基于PLC的电池开路电压、短路电流和负载电压参数的测量方法,并采用了日置HIOKI BT3562仪表测量电池的内阻参数,设计了能够进行圆形电池检测和方形电池检测的机械平台,并设计了测试系统的硬件方案和软件方案。然后,根据测试系统硬件方案,通过对系统实际控制需求的分析,完成了相应硬件的选型,并设计了系统主电路、PLC输入输出电路、伺服系统电路和参数测量电路。根据测试系统的软件方案,分别进行了下位机程序的设计和上位机软件的开发,在进行下位机程序设计时,分析了PLC的控制流程,并根据控制流程将下位机程序分为几个模块,进行了伺服电机的自动定位控制模块、手动定位控制模块和参数测量模块的的具体程序设计;在对上位机软件进行开发时,基于Delphi开发环境设计了上位机软件的多个功能界面,通过编制计算机与PLC以及计算机与BT3562仪表的通信程序以及编制Delphi调用Excel的程序,实现了测试系统的参数选择功能、自动测试功能、手动测试功能、重测功能和测试结果的显示及保存。最后,对测试系统进行了调试并在调试完成后,对测试系统进行了实验和分析了测试系统的性能,以保证电池自动测试系统符合测试要求。实际的运行情况表明,设计的锌锰电池测试系统能够对多种型号的多个电池参数进行测量,系统运行可靠,能够很好地满足测试需求。
[Abstract]:Zn-Mn battery is a common DC power source for electronic equipment. Its performance determines the service life of electronic equipment, so it is necessary to test and analyze the battery performance before the battery flows to the market. At present, there are still a lot of traditional and semi-automatic instruments in China, which need to be measured and recorded manually, and most of them have a single function. In order to test several parameters of battery, many instruments are needed, which results in a great waste of manpower and material resources. Therefore, it is of great value and practical significance to design an automatic test system for different types of Zn-Mn batteries. In this paper, a multi-parameter automatic test system based on programmable controller (PLC) and computer control is developed based on the current situation of zinc manganese battery testing equipment and the test requirement of zinc manganese battery. Among them, the CP1H-XA PLC is used as the lower computer to realize the motion control and battery parameter detection of the system, and the common PC computer is used as the host computer to realize the man-machine interaction of the system. First of all, according to the current battery parameter detection technology, this paper puts forward the measurement method of battery open circuit voltage, short circuit current and load voltage parameter based on PLC, and uses day HIOKI BT3562 instrument to measure the battery internal resistance parameter. A mechanical platform for circular battery detection and square battery detection is designed, and the hardware and software schemes of the test system are designed. Then, according to the hardware scheme of the test system, through the analysis of the actual control requirements of the system, the selection of the corresponding hardware is completed, and the main circuit of the system, the PLC input and output circuit, the servo system circuit and the parameter measurement circuit are designed. According to the software scheme of the test system, the design of the lower computer program and the development of the upper computer software are carried out respectively. When the lower computer program is designed, the control flow of the PLC is analyzed, and the lower computer program is divided into several modules according to the control flow. The automatic positioning control module, manual positioning control module and parameter measurement module of servo motor are designed. In the development of PC software, several functional interfaces of PC software are designed based on Delphi development environment. By compiling the communication program between computer and PLC and between computer and BT3562 instrument and Delphi calling Excel program, The function of parameter selection, automatic test, manual test, retest and display and save of test results are realized. Finally, the test system is debugged and tested, and the performance of the test system is analyzed to ensure that the battery automatic test system meets the test requirements. The actual operation shows that the system can measure many kinds of battery parameters, and the system is reliable and can meet the test requirements.
