FIELD: motor industry.
SUBSTANCE: disclosed is a method of controlling use of safety belts in cars. Proposed device comprises a RFID tags to interact with the help of electromagnetic field with control unit, which includes the RFID reader and logical unit. Logical unit is connected with weight sensors, sensors and speed sensor. Output signal with logical unit is fed into blocks of sound and light signalling. If one or several safety belts are fastened wrong, i.e. when the amplitude of the signal from any of labels is defined as less as compared with preset corresponding to standard mode using safety belt, a signal with logical unit engages units sound and light alarm, resembling driver and passengers on the need to fasten belts in compliance with existing rules. Note here that to ensure operation of RFID reader control unit is located on the inner surface of the cabin in its upper part at an angle φ relative to the projection of the geometric centre of its cabin floor.
EFFECT: higher reliability of instrument control of correctness of safety belt fastening in motion.
