Design On Automobile Condition Self-alarming And Remote Control System

With the development and progress of society, the quanlity ofautomonile increases. So the working quality check, the innormalcondition alarm and receiving some certain remote control, seems prettynecessary to the automobile. In this article, it will develop a kind ofequipment which can self-check working condition, offer alarming signals,percept the change of environmental light and humidity, and receivecontrol by SMS. This aims at raising the car’s safe and intellegent level onan extent.This article starts from the auto-check, alarming and romotecontrolling of automobile, introduce the current research condition anddeveloping direction in the future. With the practical need and my ownidea, the system function is defined. There is a system of car light driverand feedback, as well as a system of SMS remote control, both of whichare held with creativity on the base of the widely-used products’application.For the car light driver and feedback system and the SMS remotecontrol system, in this article, the principle analysis, algorithm research,hardware design and software writing are accomplished. It draft thecollection of light intensity and humidity in the rain and fog weather,together with the method for adjusting light irradiation intensity. Meawhile,for all the modules in the system, it designs the circuits to the use ofsampling, stabilivolt and disposing for the input control signal as well asthe output feedback signal, together with the procedure word writingmatched. All of these, it makes the driver method to the actual executionpart and the state reaction as the key emphasis in work. On the other side, the CAN bus communication protocol is led into the connection of twosystems, transfering orders by CAN message, to realize the remoteoperation to the car light execution part by SMS from cellphone.At last, in the simulation environment in the laboratory, the systemfunction is tested. And the result shows that, the working performance ofthe whole system meets the expected one. Through the process that thefault signals got from car light self-detective are analysised and convertedinto the state information, the system sends light alarm signal,automatically opens the fog light or adjust the close light intensityaccording to the external environment, and could receive the control SMSfrom the user. The system will perform the appropriate action according tothe command contet of the SMS, such as opening the lights flashing toprompt the car position, etc. The result of the whole test said above verifiesthe correctness and feasibility of this design content.
