Toll-by-weight charging ETC (electronic toll collection) system based on piezoelectric quartz sensor

Abstract

The invention discloses a toll-by-weight ETC (electronic toll collection) system based on a piezoelectric quartz sensor. The system mainly comprises a piezoelectric quartz dynamic weighing system and an ETC automatic deduction system. The piezoelectric quartz dynamic weighing system can dynamically weigh vehicles passing at high speeds with high accuracy and transmit weighing results to the ETC automatic deduction system. The ETC automatic deduction system performs automatic deduction by weight on the vehicles such as wagons and the like requiring the deduction by weight in combination with the mileage information of the vehicles, and the wagons are not required to be stopped when passing the system at highway entrances and exits, so high-speed ETC deduction is realized. Simultaneously, the system has a complete vehicle type classification function, so deducted tolls does not comprise toll by weight when the vehicles such as passenger vehicles and the like not requiring toll by weight pass the system. By utilizing the system, ETC lanes which can be shared by the wagons and the passenger vehicles can be realized, and the traffic efficiency of highways is greatly improved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to dynamic weighing and ETC. Background technique [0002] Overweight and overloaded transportation of vehicles has brought a series of hazards: disrupting the transportation market, damaging road facilities, causing frequent traffic accidents, polluting the environment along the road, and causing a large loss of state fees and taxes. In addition to speeding up legislation and intensifying law enforcement in the treatment of over-limit and overloading, an advanced vehicle dynamic weighing system is an indispensable technical means. [0003] The traditional highway toll collection is carried out by staff swiping cards and collecting cash. The biggest disadvantage is that the toll speed is relatively slow, resulting in slow vehicle traffic, which is easy to cause congestion at the toll exit, and has caused great damage to the environment around the toll station. At the same ...

Problems solved by technology

[0008] Since the current mainstream bending dynamic weighing system cannot guarantee sufficient weighing accuracy when the vehicle is driving at high speed, it is impossible to implement ETC charges for trucks, and the truck lane is still paid manually
