摘要
随着DC-DC电源模块种类的日益增多,其测试内容的复杂度也日趋增高,为手动测试带来了一定困难,鉴于此,介绍了DC-DC电源模块自动测试系统的一种设计方法,使用计算机控制单片机与可编程测量设备,通过继电器阵列的切换来实现不同的测试方法,能够实现DC-DC电源模块的全温区全覆盖参数测试。基于设计原理进行实物搭建,采用定制机柜来容纳测量设备、计算机与硬件箱,便于搬运移动;测试板可放入高低温箱,与硬件箱通过航空插头相连接。DC-DC电源模块自动测试系统的建立,不但大大提高了科研生产中的测试效率,也节省了大量的人力物力,具有一定的实际意义。
As the types of DC-DC power supply module is increasing, the complexity of the testing content is getting higher, bring some difficulties to the manual testing, in view of this, a design method of DC-DC power supply module automatic testing system is introduced, using computers to control the single chip microcomputer and programmable measuring device, and to realize the different testing methods by switching the relay arrays, which can realize the full coverage and all temperature zones parameters testing of DC-DC power supply module. The real object constructing is conducted based on the design principle, using a customized cabinet to bear the measuring equipments, the computer and the hardware box, so as to move and carry conveniently; and the testing board can be placed in a high/low constant temperature box, connected to the hardware box via an aviation plug. The establishment of DC DC power module automatic test system not only greatly improves the testing efficiency in scientific research and production, but also saves a lot of manpower and material resources, which has certain practical significance.
