Cigarette lighter has become an essential product for vehicles,whose mechanical performance is significant in driving safety and user′s experience. A system for measuring the pop-up force of vehicle-mounted cigarette lighter was designed to meet the actual demand of car manufacturers,which is professional and efficient in assessing and inspecting the mechanical properties of their products. The system can be abstracted as an embedded CPU-based small integrated electronic system including data acquisition,analysis and other functions. In the system,the DSP chip in TMS320F2812 series of Texas Instruments,which dedicates in the control area,is taken as the core processor of the system to design the acquisition system,and users’operating platform on PC is designed with Visual Basic 6.0 development environment. A complete solution based on the system request is given in this paper. The working principles of the hardware circuit are described in detail. The firmware and user interface were designed. The system has been used in the factory ultimately,and the high-precision multi-cycle measurements of cigarette lighter pop-up force has been realized. The mesuring results can be displayed,analyzed and stored in the user software of the upper computer.
