Problems solved by technology

Due to the short length of the weighing platform, the short acquisition time of the weight signal, and the installation error of the scale body, the axle load meter has low weighing accuracy.
The vehicle-type weighing equipment has high weighing accuracy, and there can only be one vehicle on the scale platform during measurement (that is, it cannot follow the vehicle continuously), so it affects the traffic efficiency
More importantly, the toll plaza environment is limited, and the slope and space are affected. The installation of the vehicle-type continuous follow-up road automatic scale requires slope adjustment, etc., which will increase the construction period and increase the cost.

Embodiment Construction

[0015] The toll collection system by weight in the present invention is composed of an axle load weighing platform, an information collection system (including a data center processor and a signal processor), an axle identifier, an infrared grating vehicle separator, and a ground sensing coil vehicle detector.

[0016] When the vehicle passes through the detection platform, the sensor signal is input to the data processing center, and the weight data of each axle of the vehicle is processed to calculate the weight and total weight of each axle. When the vehicle drives out of the weighing area, the ground sense coil and the infrared grating Signals are sent out in sequence to indicate the end of a vehicle's weighing work. The signal processor judges the number of tires, axle type and vehicle type of each axle according to the signal of the wheel axle identification sensor, thereby obtaining the axle type and the specified standard value, and comparing with the actual measured va...

Abstract

The invention provides a small-size weighing platform continuous vehicle following metering achieving method and system. A small-size weighing platform is adopted so that high accuracy can be achieved. The automatic road scale for continuous vehicle following metering is provided with the weighing platform installed on a road, the vehicle inlet end and the vehicle outlet end of the weighing platform are respectively provided with an axle recognizer and an optical grating vehicle separator, and the axle recognizers and the optical grating vehicle separators are all connected to a computer in a toll booth through a control cabinet. The automatic road scale has the advantages that weighing accuracy is higher than that of an axle load meter, manufacturing cost is lower than that of a whole vehicle weighing device, the civil engineering work amount is small, and the device can be installed in the environment with the slope and is convenient to repair.

Description

technical field [0001] The invention belongs to the technical field of truck scale manufacturing. The special equipment is a measuring device that continuously weighs the vehicle weight based on a truck scale with a small scale platform (such as 12 meters), and calculates the vehicle weight through the truck scale combined with the identification of the upper and lower scale shafts. Background technique [0002] At present, the most widely used weighing equipment in the expressway toll collection is the axle load meter (the length of the scale body is about 0.8m) and the vehicle-type weighing equipment with a large scale platform (the length of the scale body is about 18-24m). . Due to the short length of the weighing platform, the short acquisition time of the weight signal, and the error in the installation of the scale body, the weighing accuracy of the axle load meter is low. The vehicle-type weighing equipment has high weighing accuracy, and there can only be one vehi...
