ETC (Electronic Toll Collection) radio environment monitoring guarantee method, system, equipment and medium

Abstract

The invention provides an ETC radio environment monitoring guarantee method, system, device and medium, and the method comprises the steps: capturing a vehicle image, collecting ETC protocol information and ETC frequency band signals when real-time monitoring RSU equipment receives a link establishment request of vehicle-mounted OBU equipment, obtaining first vehicle information and second vehicle information according to the vehicle image and the RSU equipment, and transmitting the first vehicle information and the second vehicle information to the RSU equipment; and judging whether the vehicle position information and the abnormal type are consistent or not, if not, acquiring the vehicle position information and the abnormal type to report an abnormal alarm, otherwise, acquiring an ETC transaction result to judge whether the transaction is successful or not when the RSU equipment and the vehicle-mounted OBU equipment are disconnected, detecting whether the RSU or the OBU has a fault or not according to the ETC protocol information when the transaction is unsuccessful, and if the equipment has a fault, reporting an abnormal alarm. Whether signal interference, card carrying abnormity and equipment abnormity exist or not when the vehicle passes through the portal can be effectively monitored, missed marking and wrong marking are avoided, and reliable guarantee is provided for normal operation of a charging system.

Description

technical field [0001] The invention relates to the technical field of ETC monitoring, in particular to an ETC radio environment monitoring guarantee method, system, computer equipment and storage medium. Background technique [0002] ETC technology realizes the official operation of the toll system of segmented charging mode, and gradually realizes the free flow of expressways. The operation quality of ETC billing, RSU antenna and vehicle OBU has become the key factor of the operation quality of expressway toll system. Under the current status of system operation and maintenance management, factors such as the quality of the ETC antenna itself, equipment installation and commissioning, equipment operating environment, and equipment maintenance have become key factors to ensure the long-term normal operation of the ETC antenna. The system operation and maintenance workload of the expressway business unit The difficulty of working with the station has greatly increased compa...

AI Technical Summary

Problems solved by technology

According to statistical analysis, the existing operation and maintenance system has high requirements and large gaps for ETC gantry operation and maintenance personnel. The timeliness of information collection is poor by manual inspection and partial monitoring. The efficiency of manual intervention in triggering equipment failures and alarm processing is low. The analysis is basically based on experience, equipment failure standards are different, and the operation and maintenance department is difficult to manage in a unified manner.

[0003] The existing ETC trading environment equipment monitoring only involves collecting single equipment monitoring data in the ETC trading system, aiming at solving the problem of unilateral application of a single equipment, but the actual ETC radio environment is very complex and there are many abnormal scenarios. If only a single equipment monitoring Analysis, instead of real-time comprehensive analysis of multiple data information from multiple different devices to comprehensively monitor the ETC trading environment, it cannot effectively identify different abnormal scenarios such as signal interference, abnormal card carrying, abnormal RSU or OBU equipment, etc., and it is difficult to avoid antenna It is also difficult to provide an effective and reliable guarantee for the normal operation of the toll collection system due to the occurrence of wrong and missing labels
