The Research On Remote Monitoring System For Engines Power Of City Vehicles

It is difficult to carry through the vehicle condition remote monitoring because of the vehicle's feature of distributing, moving and little worth. Now in China there are hardly the devices of intelligent condition monitoring equipped for vehicle, especially for the native-made vehicles. The technology of vehicle condition remote monitoring can not only meet the demands of the vehicle's safety, comfort and environmental protection, but also fit the tendency that the computer technology is fusion with the communication technology and the country-wide traffic system, and become a new area of research, application and exploitation for the ITS. So there is practical meaning for studying it.In the paper, based on the situation that the being managed with the form of company for native buses and taxicabs, the native increasing vehicle's quantity, the high covering rate of GSM in China, the being charged by communication data amount for GPRS, and the actuality of the equipment condition remote monitoring and the vehicle condition monitoring & diagnosing, the overall project of vehicle condition remote monitoring is designed, the data remote transmitting is studied by experimentation, the changing rule and effect factors of diesel engine power are analyzed, the block vibration of diesel engine is checked, the practice on the remote monitoring system of diesel engine power is carried out. The detailed contents are summarized as follows:â‘ Designing the overall project of vehicle condition remote monitoring based on the communication technology and the vehicle condition monitoring & diagnosing;â‘¡Analyzing the effects of the GSM channel characteristics on data remote transmitting, and the particularities of applying TCP/IP to GSM;â‘¢Carrying out the experiment of testing time delay of the digital signals remote transmitting on GSM-Internet by building the experiment platform, and analyzing the data remote transmitting capability of the constructed data remote transmitting channels based on the experiment results;â‘£Analyzing the changing rule and the effect factors of diesel engine...
