Ye Xin, Tongqi Expressway Investigation Report
Ye Xin, Tongqi Expressway Investigation Report
On 5.25-5.28, a group of 6 people visited the Yexin Expressway in Henan Province and the Tongqi Expressway in Jiangsu Province. We mainly studied the communication modes and effects of Yexin Expressway and Tongqi Expressway.
Both Yexin Expressway and Tongqi Expressway adopt the Gigabit Ethernet network communication mode. Their communication model is still relatively advanced and mature. Yexin Expressway has been in operation for half a year, and Tongqi Expressway has been in operation for more than two years. According to their practical practice, this system is stable in operation, less faulty and easy to maintain, and guarantees the stability of transmission. The operation cost of the expressway is greatly reduced.
The communication system of Yexin Expressway uses Gigabit Ethernet technology to optimize the design of the mid-1990s. For the access network, the optimization scheme adopts the IP technology completely, and adopts the multi-layer intelligent switching device networking to provide local transmission directly on the basis of providing multi-service integrated access, and the devices of each node form a gigabit ring. network. For voice, the optimization scheme selects the voice system solution based on the softswitch design concept, and considering the compatibility with the original scheme, the optimization scheme adopts the softswitch IP voice system of “IP+TDM” dual plane architecture. Specifically, the optimization scheme is the integration of "MSTP+IP integrated access Gigabit ring network technology + IP/TDM dual-plane architecture softswitch voice technology".
At present, most of the highway communication systems that have been put into use are used to separate the network for the transmission of the carried services, the transmission of the charging receipts, the transmission of the monitoring signals, and the transmission of voice signals. This results in waste of resources and utilization of bandwidth. Not high, maintenance troubles and many other unfavorable factors. With IP Gigabit Ethernet, many services can be integrated into one communication network, increasing bandwidth utilization, enhanced management, and easy maintenance.
Through field visits to Yexin Expressway and face-to-face conversations with them, it can be seen that their communication systems are relatively stable and the communication effect is better.
The Tongqi Expressway adopts full road section monitoring, and the monitoring center centralizes centralized management and dispatching. In the communication system of Tongqi Expressway, the Gigabit Ethernet data transmission platform is adopted to make the structure of the data network simpler, satisfying the requirements of real-time and synchronization, and adapting to the development of data to broadband. In the video image and the external field low-rate data transmission, the data video and audio access device is used to digitally process the image and the data, which conforms to the development direction of the digitalization and networking of the communication technology, that is, the triple play; A high-speed camera is deployed every two kilometers to achieve full-range monitoring, which provides more intuitive monitoring of road conditions, traffic conditions, accident conditions, and meteorological conditions, thus eliminating the need for an emergency telephone system that is less valuable.
The whole road section monitoring, centralized management and cancellation of the traditional toll booth monitoring room, unified management of the special situation of the toll business, unified the problem processing method, and avoided the different processing results of a toll station for special services. The toll booth and the monitoring center directly contact each other through IP telephones, report special services, and concentrate all the rights on the station to the monitoring center. The station only handles normal charging services, which saves a lot of labor costs and facilitates unified management. The monitoring center implements the recording and storage of the toll booth voice, which not only can supervise the civilized service of the toll collector, but also provide evidence for handling special events. The monitoring center directly monitors, schedules, and coordinates the road sections and toll stations directly, which facilitates the monitoring center's handling of various situations on the toll stations and sections.
Both Yexin and Tongqi Expressway use the Gigabit Ethernet IP data transmission method to IP and voice the video and video, and transmit the data through an IP Gigabit Ethernet network. Compared with the traditional communication method, the transmission mode has the following characteristics: the input cost has been reduced; the effect is relatively stable; the maintenance is relatively simple; the management is also relatively simple, especially for the centralized management scheduling under the company system.
Analysis of the results of the investigation on Yexin and Tongqi Expressway, the company believes that the company can adopt the Gigabit Ethernet network communication method.
