METHOD FOR CONTROLLING AND MONITORING MOVING VEHICLE Russian patent published in 2005 - IPC

FIELD: technologies for controlling and monitoring vehicles movement.

SUBSTANCE: on moving vehicle navigation signals are received from satellites belonging to global radio-navigation system, position coordinates are determined, time and speed of vehicle, data packet is formed in form of SMS message and this message is sent via mobile communications system to central dispatching station. At the latter data is periodically received from current and other vehicles, it is processed, stored and displayed on electronic map of locale, and in case of special situation appropriate message is sent to vehicle through mobile communications system. After receiving message certain subsystems are engaged or disengaged at vehicle. Method is different from other known methods, because at vehicle current events are additionally constantly ordered and recorded in form of electronic log with use of modes masks and forming of byte-mask of format of data output for event of appropriate mode, and during forming of SMS-message header is formed after recording of service data. This data includes mode identifier and event identifier, then serially data blocks, including data output format mask field, number field, events number field, and data field of these events. Byte-mask of event prepared for transfer is recorded in mask field of appropriate data block, number of event is recorded in number field and event number field., and data of appropriate event - in data field of this data block. For events taking place concurrently byte-masks are joined according to logical OR rule and recorded in form of resulting byte mask in mask field of appropriate data block, numbers of events - in number field and events number field, and data from these events is recorded serially in data field of appropriate data block. When SMS message is fully filled with data blocks, the message is sent to dispatching station, where it is received, events are deciphered using analogical masks and monitoring of appropriate vehicle is performed. Also, in query mode from central dispatching station a message is formed with individual masks, adapted for appropriate event, and sent to vehicle, where according to masks necessary event is taken from log, appropriate SMS-message is formed on basis of above-said rules and is then sent to dispatching station.

EFFECT: more complete monitoring from central dispatching station and possibility to form messages concerning various events in a vehicle.
