Vehicle-mounted unit of 5.8 GHz electronic toll collection system

Abstract

The invention discloses a vehicle-mounted unit of a 5.8 GHz electronic toll collection (ETC) system, comprising a primary processor unit, a 5.8 GHz wireless communication module, an IC (integrated circuit) card interactive module, an information displaying module, a power management module, a JTAG (joint test action group) debugging interface and an anti-dissembling module, wherein the 5.8 GHz wireless communication module is connected with the primary processor unit to realize DSRC (dedicated short range communications) short distance wireless communication which meets the Chinese national standards of the ETC; the IC card interactive module carries a double-interface CPU (central processing unit) card and can be compatible with an artificial semi-automatic charging way; and the power management module utilizes a solar battery to charge a lithium battery. The 5.8 GHz wireless communication module of the vehicle-mounted unit receives arousal signals and data which are transmitted from a RSU (rate-sensor unit) and sends to the primary processor unit; and the primary processor unit reads and writes the double-interface CPU card according to the received data and transmits vehicle / trade information to the RSU, so as to realize electronic toll collection.

Description

technical field [0001] The invention relates to a vehicle-mounted unit of a 5.8GHz electronic non-stop charging system. Background technique [0002] At present, all expressways in our country need to pay for passage, and the toll methods mainly include manual toll collection and manual semi-automatic toll collection. However, with the rapid construction of the national highway network and the continuous growth of traffic volume, the traditional highway toll collection methods can no longer meet the needs of highway toll collection management, and the problems caused by manual toll collection and manual semi-automatic toll collection are becoming more and more prominent. Mainly manifested in the following points: [0003] 1. Pass tickets are issued at the entrance, and pass tickets are collected at the exit. Vehicles need to stop twice, resulting in a decrease in road traffic efficiency. The traffic efficiency of toll stations has become a bottleneck restricting the improve...

AI Technical Summary

Problems solved by technology

[0003] 1. Pass tickets are issued at the entrance, and pass tickets are collected at the exit. Vehicles need to stop twice, resulting in a decrease in road traffic efficiency. The traffic efficiency of toll stations has become a bottleneck restricting the improvement of road traffic efficiency. Many road sections have traffic jams at toll stations Happening

[0004] 2. There is a problem of different standards for manual identification of vehicle models

In the actual charging work, there are often situations where the actual tonnage of the vehicle does not match the tonnage marked on the driving license. Only by manually distinguishing the model and tonnage, there is a big difference, which leads to inconsistent charging standards and often causes on-site disputes

[0005] 3. Cash transactions have disadvantages

The speed of cash transactions is slow, which leads to the inability to increase the speed of vehicles; corruption and cheating are prone to occur in the toll collection work, resulting in the loss of fares and chaotic financial management.

[0006] 4. High infrastructure and labor costs

Due to the traditional charging method, it is necessary to build a huge toll plaza and toll station facilities at the entrance and exit of the expressway, and the infrastructure cost is relatively high

Moreover, manual participation in the charging process is required, and labor costs cannot be saved

[0007] 5. It is not conducive to the promotion of highway network toll collection and highway information management

However, due to the early start of these companies, the 5.8GHz electronic tags produced by them are technically not fully in line with the provisions of my country's ETC & DSRC Chinese national standards

In the prior art, there is no vehicle-mounted unit of the 5.8GHz electronic non-stop charging system for road charging that meets the national DSRC standard
