Description
Technical Field
The invention belongs to the technical field of traffic, and particularly relates to a highway networking toll collection system.
Background
With the implementation of ETC networking, the elimination of cross-regional toll stations, and the vigorous construction of information systems in recent years, information infrastructure and related industries have rapidly developed, and highway networking toll collection systems have risen to important information systems affecting the national civilians. The intelligent, precise and humanized toll service of the highway and nationwide production of information security becomes the mainstream. An intelligent and safe highway toll collection system becomes a necessary way for building an intelligent high speed.
The networked charging system generally adopts a four-level charging system of 'toll lane-toll station-charging center of each operation company-charging settlement center'. The core of each stage of the site is computer equipment which is connected into a network through an Ethernet switch. The original charging data collected by the toll lane is transmitted to the toll station in real time through a computer network, and the toll station concentrates the collected data and then transmits the concentrated data to the toll settlement center and the corresponding toll center of the operation company. In the charging settlement center, the charge of each exit is divided and calculated according to the vehicle type of the vehicle, the road section through which the vehicle actually runs and the mileage to obtain the accounts receivable of each road section, and then the accounts receivable are stored in a database of the charging settlement center, and the result of the settlement is sent to the charging center of the corresponding operation company. However, as ETC users also grow sharply, new challenges are brought to the toll collection system, mainly expressed in:
(1) the number of the users is increased sharply, so that the number of the state lists is increased from 1500 ten thousands to 6000 thousands, and the issuing and the inquiring of the state lists affect the normal transaction of the lane system.
(2) Antennas are arranged on both the ETC special lane and the hybrid lane, and a large number of antennas are arranged in a toll plaza, so that transaction areas are overlapped, adjacent lane interference and repeated fee deduction are caused, and the problems are urgently solved.
(3) The fee display optimization project of on-line in 5/6/2020 increases the operation on the OBU path information, the traffic logic of the lane is complex, the transaction success rate of the lane is reduced, and the problem also needs to be solved.
(4) After the provincial toll station is cancelled, in order to ensure the timeliness and the accuracy of online charging, the road network center makes a clear requirement on the timeliness of part-station data transmission. On one hand, the data transmission efficiency from the lane to the station and from the station to the center needs to be improved, and on the other hand, the data transmission needs to be monitored intensively so as to find and diagnose the transmission problem by self.
(5) The charging system adopts a traditional C/S framework, a server of a charging station and a lane controller of a charging lane are all in independent working modes, under the current mode, program upgrading and issuing, charging module upgrading and issuing and state list issuing usually need a plurality of files to issue, and if a certain file fails to issue, upgrading and issuing will be failed. The upgrading state of the software needs to be checked manually, and the software which fails to be upgraded needs to be manually delivered again. With the expansion of road networks, the adoption of manual checking and re-issuing has become an operation and maintenance bottleneck of the networked toll collection system, and the requirements of canceling the blacklist, the billing module and the program for fast upgrading and issuing after the provincial toll station is cancelled are difficult to meet.
(6) The development of the expressway for decades has the disadvantages that the network architecture of an electromechanical system of the toll lane is complex, the types of external equipment are various and the concentration is not high, the types of equipment protocols are various and are not uniform, the system construction interfaces are multiple and complex, the comprehensive real-time monitoring on the toll system cannot be implemented, the difficulty of system construction, maintenance and repair work is high, and the like, and the expressway is also a problem for the operation management department of the expressway.

According to one or more embodiments, the networked expressway toll collection system based on virtualization and intelligent edge management aims to solve the security problem that software and hardware of the networked expressway toll collection system are not localized. On the premise of considering the development trend of domestic software and hardware, the hardware architecture compatible with the existing toll station and lane is fully considered. The station level software and the lane level software can adapt to the localization hardware and the existing hardware (X86 architecture), thereby protecting the existing investment cost.
The method is characterized in that a domestic server and an industrial personal computer hardware chip are adopted, an ARM architecture is adopted, a Centos7.4 edition is selected as an operating system, and MySQL is selected as a database.
According to one or more embodiments, the virtual intelligent edge management-based highway networking toll collection system solves the problem caused by the adoption of a 'thick client' mode in the traditional toll lane software.
Since the conventional lane charging system integrates all functions into a lane controller, including status list inquiry, rate calculation, data transmission, etc. With the increasingly complex business and the increasing status list, the requirement for the computing capacity of the lane is increasingly increased, so that the existing industrial personal computer is overwhelmed, the software performance is also continuously reduced, the problems of low ETC transaction success rate, unsmooth operation and the like occur, and the stability and the reliability of the system are urgently required to be improved.
Aiming at the problem, the embodiment of the invention adjusts the software architecture, changes the 'fat terminal' mode into the 'thin terminal' mode, reduces the internal logic complexity of lane software, reduces the pressure of a lane industrial personal computer, concentrates the capability of the industrial personal computer on the functions of equipment state acquisition, ETC transaction, man-machine interaction and the like, keeps the high-efficiency operation of the industrial personal computer, and improves the stability and the reliability of the system. Specifically, the method comprises the following steps:
(1) solving the status list problem
And adjusting a software architecture, changing a 'fat terminal' mode into a 'thin terminal' mode, and transplanting the downloading, loading and inquiring functions of the state list to a virtualization platform. The operation parameters (including blacklist parameters, green access reservation list parameters and the like) of all the lanes governed by the toll station are only issued to the virtualization platform and do not need to be issued to the lanes.
