SECURITY SYSTEM FOR GAS WITH AUTOMATIC STARTING OF ENGINE Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to devices for preventing unauthorized use of cars. Proposed system contains central control unit to input of which limit switches of doors, hood and trunk are connected, impact, volume and temperature pickups, paging communication receiver and antenna to receive User's identification signals and to control car from radio trinket held by User. Control units of door electric drives, light and sound signaling, car movement interlocks, alarm radio transmitter and engine remote starting and shutting down units are connected to outputs of central control unit. Programmer-indicator and timer are coupled with control unit. System is provided also with series-connected carbon monoxide detector and microcontroller whose output is connected to additional input of control unit. Microcontroller is made for multilevel threshold processing and shaping of control signals depending on level of carbon monoxide concentration in atmosphere. Control unit is made for forming control actions onto light and sound signaling units and engine starting and shutting down units. EFFECT: improved safety in operation and servicing of car. 3 cl, 2 dwg
