FIELD: technology for controlling movement of vehicles, possible use for measuring number and speeds of moving vehicles, registration of their position, including railway cars, rolling down from sorting hill. ^ SUBSTANCE: along the line, passing through movement zone of vehicle below road surface, electromagnetic field is formed by emitter, which is changed by vehicle. Further, change of field is transformed by receiver to electric signal and the latter is registered. Number of vehicles crossing the line is determined by number of changes of signal amplitude. ^ EFFECT: increased reliability of registration of number of vehicles, increased resistance to interference when determining speed, movement direction and position of vehicles. ^ 15 cl |
