Abstract

The combination test device includes mainboard module, and functional test modules connected to the mainboard module through serial port. The mainboard module includes host, display unit, input unit, printing and output module, serial interface, expanded memory, timing module. The host can be PC, notebook computer or industrial computer. Testing and controlling board of instrument and relevant interface board of instrument accomplish a functional test. Single or multiple functions can be combined quickly by adding or reducing relevant testing and controlling board as well as corresponding interface board in order to add or reduce functional test modules. Advantages are: simple combination, eliminating interference between modules, easy of maintenance, taking full advantage of resources, and shortening cycle for developing produce.

Description

1. Technical field: [0001] The invention is a combination test device for the safety performance of household appliances, which belongs to the innovative technology of the safety performance test device for household appliances. 2. Background technology: [0002] At present, the household appliance safety performance testing device has the following methods for measuring safety performance parameters (insulation resistance, leakage current, grounding resistance, withstand voltage, voltage and current power, and low-voltage start-up): [0003] 1) In the past, a special system composed of relay control and a single-chip microcomputer measurement and control was used. The hardware modular design was not used, and new functions needed to be re-developed, which lengthened the product development cycle; using this design method, the previous development When personnel change, subsequent developers will spend a lot of time and energy getting familiar with unfinished products, resul...
