Title:
光学センサおよび磁気センサを用いて車両の存在を連続的に検出するための方法および装置
Document Type and Number:
Japanese Patent JP2013506178
Kind Code:
A
Abstract:
In the present invention there is described a method and apparatus for the continuous, non-intermittent, detection of vehicles based on detecting the sharp change in illumination caused on the flooring under a vehicle when this arrives or departs, and on the use of said detection to activate a magnetic sensor the sensitivity of which is adjusted to detect only those magnetic disturbances sufficiently large to be able to be attributed to a vehicle which is over the sensor. Both the light sensor and the magnetic sensor are connected directly to a digital controller without the need of active electronic components or their own or a shared power supply source. The detector may be fixed or portable, wireless or connected by cables, and may operate independently or as part of a sensor network.
