On August 13, 2020, Yueqing Bay Railway was officially put into operation，As a rear channel connecting and radiating the mainland of Yueqing Bay Port area，The passage of the Yueqing Bay Railway means that goods can be transported directly by rail to the bay area，Significant savings in transportation costs，And greatly promote the development of port transport, port industry, modern logistics and ship building in the region。

Yueqingwan Railway has an overall operating mileage of more than 70 kilometers, and its complex terrain poses great challenges to the construction process.There are 32 Bridges on the whole line, about 15.96 km, 18 tunnels about 41.21公里。There are 6 stations and a dispatch office;The locomotive generally belongs to the special line area operation, the line design running speed of 80 km/h, of which the railway Huangtian to Shenfang section running speed of 120 km/h。

The nerve center of the whole railway (wireless train dispatching system) is applied to the digital wireless train dispatching system independently developed by Geektong, which fully considers the complex and varied terrain and greater construction difficulty of Yueqing Bay Railway, combines a variety of technologies to reduce construction costs and maintenance costs and optimize the construction process。

The characteristics of this system

The DMR digital system was adopted，Through the combination of hardware and software，Realize the big triangle communication of train scheduling (between the dispatching operator, the station attendant and the locomotive driver), and the small triangle communication (between the station attendant, the locomotive driver and the conductor)，And take into account public works, electrical and logistics services，Crossing joint control, section protection communication system and other functions。

The system realizes the following functions:

1.  Complete wireless signal coverage of all station working areas within the range;

2.  Train shuntingThe business center is networked with all stations, and can contact station duty officers and locomotive drivers on the move at any time;

3.  Station attendant and locomotive driver in the area covered by the stationRealize intercom communication;

4.  The locomotive driver can realize wireless intercom with the station attendant in the covered area when entering the station or driving;

5.  The train shunting center can issue the dispatch plan task order according to the information mode, and the station duty officers and drivers can reply and confirm in real time;

6.  The shunting center always grasps the position of the locomotive running section;

7.  Crossing joint control, such as road joint control, road vehicle joint control and road machine joint control;

8.  Interval protection communication, such as communication channel sharing and cross-station roaming, recording management, scheduling monitoring and guard switching

In the system，We equipped the new MOTOROLA P3688T+ digital walkie-talkie (four-hole) for the operating driver，The walkie-talkie realizes: call recording playback, GPS/Beidou positioning and time correction, intelligent audio，Long battery life and many other enhancements，As a result, higher work efficiency is obtained。

In the context of digital transformation, many industries have begun their own journey of reform, such as forestry, mining and public security industries, among which the railway industry is the first to bear the brunt of the analog to digital upgrade。In this process, Geektong with a consistent spirit and unremitting attitude to ensure that the customer's transformation journey is smooth and smooth, and to ensure excellent service and high-quality products, customer satisfaction smile is our biggest return。
