Design and Implementation of Automatic Testing System for Room Temperature Function Parameters of Refrigerator Controller

摘要: 本文主要针对制冷机控制器常温功能参数自动测试系统进行设计研究。论文首先分析了制冷机控制器常温功能参数的测试原理，然后对制冷机控制器常温功能参数测试系统总体结构框图进行了说明，最后介绍了自动测试系统工作原理，并详细介绍了测试系统的硬件组成、整体流程设计和软件功能设计，最后对制冷机控制器的常温功能参数进行了测试。该方法使用价格低廉的普通三相直流无刷电机代替价格较高的制冷机，降低了测试成本；并且制冷机从启动到达到控温状态还需要较长的时间，因此该方法也使测试效率有较大的提高。

Abstract: This article mainly focuses on the design and research of an automatic testing system for the normal temperature functional parameters of refrigeration machine controllers. The paper first analyzes the testing principle of the normal temperature functional parameters of the refrigeration machine controller, then explains the overall structure diagram of the refrigeration machine controller normal temperature functional parameter testing system, and finally introduces the working principle of the automatic testing system, and details the hardware composition, overall process design, and software function design of the testing system. Finally, the normal temperature functional parameters of the refrigeration machine controller are tested. This method uses a low-cost ordinary three-phase DC brushless motor instead of a more expensive refrigeration machine, reducing testing costs; And it takes a long time for the refrigeration machine to reach the temperature control state from start-up, so this method also greatly improves the testing efficiency.
