A vehicle-mounted vehicle experiment data acquisition system

Abstract

The invention discloses a vehicle-mounted automobile experimental data acquisition system. A first analog signal acquisition module and a temperature acquisition module are connected with a corresponding sensor in an experimental environment information measuring unit, and the temperature acquisition module and a second analog signal acquisition module are connected with a corresponding sensor in a vehicle information measuring unit to collect vehicle information and experimental environment information and to measure analog signals and temperature signals. A global position system (GPS) information measuring unit collects information of longitude and latitude, vehicles, vehicle accelerated speed and altitude. The collected data are all converted into a controller area network (CAN) data package and transmitted to a host machine computer through a CAN bus and a universal serial bus (USB) to CAN communication module. 12-V working voltage is supplied to the first analog signal acquisition module, the second analog signal acquisition module, the temperature acquisition module and the GPS information measuring unit through a power plug of a cigar lighter. The vehicle-mounted automobile experimental data acquisition system achieves comprehensive acquisition on the experimental information, shortens the experimental time and reduces the experimental cost.

Description

technical field [0001] The invention relates to the field of automobile test equipment, in particular to a vehicle-mounted automobile experiment data collection system. Background technique [0002] The road test of the whole vehicle and the test on the chassis dynamometer of the laboratory are the basic test methods for the calibration test and inspection of the car by the car manufacturer and the car testing agency. Through these tests, various performances of the car can be improved and the quality of the car can be guaranteed. In these tests, the test environment information and vehicle status information are important factors that affect the test results. Accurate measurement of these information can better grasp the test time and process the test results. [0003] In the process of realizing the present invention, the inventor finds that at least the following disadvantages and deficiencies exist in the prior art: [0004] 1) In the actual road test, there is currentl...
