Geomagnetic detector MACNODE-3

An all-buried geomagnetic detector, the MACNODE-3 is compact, highly reliable, easy-to-install device able to meet various requirements in a field work environment. Wirelessly transmitting detected data to the receiver, it can conveniently configure, debug, and test equipment via the wireless network; with multiple work modes for different application scenarios, it can also set and adjust functions according to the scenario and requirements. It has a long lifecycle and can normally work more than five years (on the basis of 10,000 vehicles/day).

Detection functions:

Work frequency for detection samples: adjustable 1-100Hz according to the application scenario;

Traffic volume: the accumulated number of vehicles passing a certain section within a certain detection period;

Vehicle speed: the speed of vehicles passing a certain detection section;

Inter-head interval: the time interval between the head ends of two consecutive vehicles in a procession of vehicles moving on the same lane.

Lane-occupation time: the time for the accumulated occupation of vehicles passing a certain section;

The report of collected road traffic data can be made in real time or once every minute. Typically, reporting every minute applies to traffic guidance applications, while real-time reporting is used for smart traffic light control or camera shooting at the checkpoint.
