This invention provides a reference threshold setting device for an axle counting
system, comprising: a main
control unit for collecting button operation information and generating a safe reference threshold setting command; and a method for setting a reference threshold for an axle counting
system, comprising: the axle counting board collecting detection parameters of axle counting detection points in real time, and the detection parameters when there are no vehicles within a specified range of the axle counting detection points being the target object for setting the reference threshold; the method further comprising the setting device sending a reference threshold setting command to the axle counting board through the axle counting host
bus or the axle counting board interface. Compared with the prior art, this invention has the following advantages: it uses
software commands to set the current no-
vehicle detection parameters as the reference threshold, eliminating the need for hardware debugging of the reference threshold, greatly reducing the
workload of axle counting
system debugging, and making on-site debugging of axle counting equipment more convenient; by changing the reference threshold adjustment method to
software adjustment, there will be no parameter drift or hardware damage.
