摘要
为了快速检测车用油量传感器,提高检测效率,设计了一种采用DSP为主处理器的手持式干簧管油量传感器检测方案。该装置采用两线制电阻测量法进行传感器位置电阻测量,通过干电池对整个系统进行供电,以TI的TMS320F28335为核心控制器,并通过控制器片内高速ADC模块进行传感器电压采样,对采样数据进行处理分析,最终将检测结果通过12864LCD屏显示出来。经多次测试,该装置可快速准确检测出干簧管油量传感器故障所在,实现了手持式检测,性能稳定,使用方便且易携带。
In order to quickly detect the oil quantity sensor and improve the detection efficiency,a scheme about handheld oil quantity sensor of reed switch based on DSP is designed.The device adopts two wire resistance measuring method to measure the position resistance of the oil quantity sensor.By powering by dry batteries,taking the TMS320 F28335 of TI as the core controller,collecting the sampling of the voltage of the sensor through the high speed ADC module in the chip of the core controller,and analyzing the sampling data,the test results are finally displayed through the 12864 LCD screen.After many tests,the device can quickly and accurately detect the fault of the reed switch oil quantity sensor and can be made of the hand-held.The device is stable,easy to use and easy to carry.
