Hello, it's my pleasure to answer for you. The expressway communication system is called the high-speed public An important support system for road modernization management. The communication system is one of the three major systems of the expressway. This system is divided into two parts, one is the internal communication system and the other is the external communication system.
The three major systems basically include the construction of "monitoring system", "charging system" and "communication system". Expressway supervisionThe control system is mainly composed of three major parts: information acquisition subsystem, monitoring center and information provision subsystem. Information acquisition subsystems include: vehicle detectors, meteorological detectors, emergency telephones and patrol cars.
[Answer]: There are three main functions of A, B and D highway communication systems, that is, providing communication means, providing information transmission channels, providing emergency calls for help and help and other services.
The expressway communication system is the transmission and network basis of the toll system and monitoring system, and is an important part of the three major mechanical and electrical systems of the expressway. While explaining the composition and characteristics of the communication system of the Fokai Expressway, this article also puts forward some suggestions for the maintenance of the communication system.
1. Hello, it's my pleasure to answer for you. The expressway communication system is known as an important support system for highway modern management. The communication system is one of the three major systems of the expressway. This system is divided into two parts, one is the internal communication system and the other is the external communication system.
2. Right. The communication system is a bridge, responsible for the connection of various systems and the transmission of data; the monitoring systemFor "eyes", responsible for the inspection of highway road conditions, the confirmation of events, and provide decision-making data for highway operators.
3. Mapping is the process of loading signals of various rates into the corresponding standard container (C) after code speed adjustment, and then adding channel overhead (POH) to form a virtual container (VC). Frame phase deviation is called frame offset.
4. Yingda Expressway is called Gsm Introduction Yingda Expressway is an expressway in Shandong Province, China, with good road network coverage and transportation conditions. GSM is a wireless communication standard and one of the most commonly used mobile communication standards in the world at present.

This system is divided into two parts, one is the internal communication system and the other is the external communication system.
2. Right. The communication system is a bridge, responsible for the connection of various systems and the transmission of data; the monitoring system is the "eye", which is responsible for the inspection of highway road conditions, the confirmation of events, and the provision of decision-making data for highway operators.
3. The official name of "Information Expressway" is "National Information Infrastructure (NII)", which comes from the United States and is the main body of modern national information infrastructure.The so-called "information highway" does not refer to the traffic highway, but to the high-speed computer communication network and its related systems.
The highway communication system is mainly composed of optical fiber digital transmission system, voice exchange system, conference television system, call service center, emergency telephone system, cable broadcasting system, communication power supply system, optical cable engineering and communication pipeline engineering, etc.
The highway communication system is mainly composed of optical fiber digital transmission system, digital program-controlled switching system, emergency telephone system, communication power supply system, optical cable engineering and communication pipeline engineering, etc. Cable broadcasting systems should also be added to long and special tunnels and special bridges.The dispatch command telephone system belongs to the monitoring system.
The communication system of a highway is generally composed of six major parts: optical fiber, program control, emergency telephone, power supply, optical cable and pipeline.
Communication system composition The communication system of Fokai Expressway is mainly composed of four parts, including optical synchronous digital transmission system (SDH), program-controlled switching system (PABX), roadside emergency telephone system (ETS), communication power supply (POWER) and so on.
The communication system is roughly composed of three parts: the transmitter (sending source and sending device), the channel receiving device (the receiving device), and the noise source. The source is the source of information, and its function is to convert the original signal into the corresponding electrical signal, that is, the baseband signal.
The highway communication system has begun fromThe internal communication of a single road has changed to a wide area communication in the road network environment. Each on-site monitoring station on the highway has a large amount of monitoring data that needs to be transmitted to the monitoring center in time; each toll station also has a large number of data files to be transmitted to the toll center regularly, and these transmission tasks are undertaken by the communication system.
