The sensor is the input end of the detection system, it can be measured non-power is converted into electricity. The role of the signal conditioning circuit is the acquisition of the sensor from the scene over the non-electricity after a certain treatment, it is converted into a voltage, current or frequency having a certain power signals, etc., Acer Aspire 6920 battery in order to promote the subsequent stage of the display circuitry, the data processing circuit, and implementing agency. The notebook battery data processing or signal processing device sent to the voltage and current signals through the monitor display. The data processing device used to test the results of analysis, the operation of processing. 3 virtual instruments in the car 3.1 virtual instrument in the detection of car dashboard Bring in automotive instrument mass production while another problem is that the production of the finished product inspection. The instrument assembly Hyundai Motor Information Center, the quality of its production, related to driving safety and vehicle quality. Due to the upgrading of the car dashboard, new products continue to appear rather old instrument no exit to use, how to design a can for various models instrument testing equipment used in automotive instrument detection has become an important and extremely Rich practical significance of the subject. Through the the NI company's hardware and software products on the entire detection system design using the NI PXI Series board instrumentation required for testing a variety of analog, laptop battery digital switch, K-Line, CAN and other signal parameters, On this basis, re-use NI LabVIEW software to design the entire test system, Acer Aspire 5750g battery the ultimate goal is to develop a compact, flexible, high reliability and a portable detection system in automotive instrument detects it for most models, analog generate instrumentation required for real-time acquisition of a variety of signal information, and communicate via CAN interface with the instrument under test, in order to achieve the vehicle status information feedback.
