Development Strategy Analysis Of Shandong Expressway Video Voice Linkage Platform

Toll management system occupies a very important position in the whole operation system of expressways.Personnel,toll collector,monitor,management personnel and so on,the evolution of charge management mode,from the original pure artificial model to ETC(freeway no parking fee),mobile payment and manual charge of the three coexistence of the model.The original management mode which is the original monitoring center of the branch of the company-the toll station monitoring center-the toll collector has too many personnel and low efficiency.In additional,there is a distortion in the process of information transmission.In order to improve the working efficiency and reduce the intermediate links of the information transmission,the centralized monitoring and control will be realized gradually.The three-level management mode of the original monitoring center of the branch of the company-the toll station monitoring center-the toll collector is gradually replaced by the two-level management mode of the monitoring center of the branch company-the toll collector.The premise of reducing personnel and improving efficiency is that there is corresponding equipment support during operation.the original part of the manual operation can be completed replaced by the computer,which makes the charge monitoring system automated and intelligent.In the Shandong Expressway,the video surveillance system and the digital controlling system are independent from each other.When the supervisor receives the phone call from the toll collector,it needs to find the corresponding video image manually according to the toll station and the toll lane of the toll collector.This process of search consumes much energy of the monitoring personnel.According to the requirements,we want to achieve that when the stuff is answering the phone,he screen can automatically displays the video information of the booth and the corresponding lane where the caller of the current call is located,based on the premise of saving the cost.We need to add a video-to-speech software and related equipment such as voice and server to integrate the highway video surveillance system and the digital program control exchange system into one system.We also need to formulate the corresponding mapping matrix so that the telephone number corresponds to the monitoring channel.What's more,the system connects the phone and software to achieve feedback when phone call comes in.This can greatly reduce the workload of monitoring personnel,and ultimately achieve the purpose of centralized monitoring.This paper mainly describes the system requirements,the overall design,the functions of the main modules,the detailed design of the software and the implementation methods of the key technologies.The methods and conclusions given in this paper have some significant reference for the fusion and transformation of the video monitoring system and the digital program control exchange system in the future centralized monitoring and control of the expressway.
