Research Based On Remote Wireless Monitoring And Control System Of Vehicles

With the development of the intelligent control theory and technology, the study ofintelligent traffic system is more and more widely. Driverless cars, that is, smart cars asthe core elements of intelligent traffic system, for the rapid development of the intelligenttraffic system have great influence, and wireless data transmission technology is thefoundation of the smart car can run efficiently, the smart car research and developmentare of great value. This paper mainly studies based on WIFI and3g network of smart carremote wireless control system implementation process and data transmission, etc.First, design and set up for wireless data transmission module, client module andcontrol module as the core of smart car control system for vehicle model, analyzed thecomposition and function of each module parts of; Then, developed by the wireless routermodification design and special processing and wireless data transmission module. And itas a middle bridge, through the WIFI or3g network wireless connection make customerend and control end; Then, based on a PC or mobile phone is the Android client interfaceand manipulation of the embedded system based on STC series microcontroller chips,L298N series motor driver chip as the core control module. In addition, the client and thereal-time data transmission between control end, through the design of the communicationprotocol between them and the combined simulation control module, to verify the datatransmission process of the control system of smart car; Finally, the design of each moduleare combined, build car remote wireless control system and field experiments, verify itsfeasibility.The experimental results show that, this paper builds the remote wirelessmeasurement and control system of smart car, can operate through a PC or mobile phoneclient interface, using the WIFI or3g network two kinds of wireless data transmissiontechnology to realize the intelligent car forward, backward, turn, deceleration and stopfunction; At the same time in the process of experiment, wireless data transmissionmodule to be able to install the smart car camera video images, and other measurementdata were collected through the wireless network real-time back to the client, and thenthrough the client control interface in real time to check the smart car travel status, and acorresponding control command to make smart car to follow the operation personnel willtravel, achieve a certain effect, thus the safe operation of the car for the future ofintelligent control to provide technical support.
