AI Technical Summary
Technical Problem
The existing shaft counting equipment requires hardware adjustments for each detection point after installation, which results in excessively long equipment debugging time, and electrical adjustments may cause parameter drift or hardware damage.
Method used
The axle counter collects detection parameters in real time, sets reference thresholds when there are no vehicles, and stores them in non-volatile memory. It then uses a communication protocol for secure software adjustment, avoiding hardware adjustments.
Benefits of technology
Significantly reduce equipment debugging workload, avoid parameter drift and hardware damage, improve debugging efficiency, and ensure the safety and reliability of the axle counting system.

Abstract
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.
