The difference between the dispatch telephone system and the official telephone system

1. Different functions: The dispatch telephone system is used for industrial production dispatch. Generally, there is a dispatch desk controlled by the dispatcher. There are telephone stations or loudspeakers in each area that needs to be dispatched, and you can also communicate with the operator through the dispatch phone.

2. Official telephone: It is a telephone system used for daily office work, which can realize internal dialing, external dialing, external direct entry and other functions, and can also be used as an emergency communication means for special telephones.

3. The dispatch point is the same. The official telephone system is controlled by the control center program-controlled switchboard, Henggang vehicle segment official telephone users, and station official telephoneIt is composed of supporting equipment such as household, network management system, billing system, number checking system and recording system. The two dispatch points are the same. The dispatch telephone is used as an internal telephone system for command and dispatch production within the enterprise.

4. Administrative switches and dispatch switches are both digital program-controlled switching equipment, but due to different fields of equipment use, there are many differences: function comparison. As a professional communication system in special industries, the command and dispatch system requires many functions that ordinary administrative telephone exchanges cannot provide.

5. This kind of application generally has an independent large account and an independent internal small account for each extension. There is no cost to call each other's small numbers between internals, which reduces the daily application cost.

What are the consequences of the failure of the power scheduling communication system

Safety.The communication failure of the substation circuit breaker will destroy the function of the substation DC system if it is mild, and it will cause fire or short circuit, so it will have a safety impact. The communication failure of the substation circuit breaker has a safety impact. A substation refers to a place in the power system where voltage and current are transformed to receive and distribute electrical energy.

A large short-circuit current is generated, or overvoltage causes damage to the equipment. The frequency and voltage drop, and the system is stable and destroyed, resulting in the collapse of the system, causing large-scale power outages, or endangering human lives, and causing major economic losses.

Parking report. C3 class is the core technical equipment and safety key system of high-speed railways that control the safe operation interval of trains in real time and prevent trains from overspeeding. In order to avoid car accidents caused by poor communication, trains that encounter emergencies such as communication failures will immediately stop and report to the train management center to send someone for repair.

What does the substation dispatch communication system consist of

The power dispatch automation system consists of the master station (dispatch terminal), the factory station terminal (transformer, power station terminal) and communication channels. The main functions are remote: telemetry, telemetry, remote control, remote adjustment.

Mainly monitoring information, specifically RTU, protocol converter, switch, PCM, optical fiber, SCADA server and user terminal, the process from acquisition, conversion, modulation, transmission and feedback.

The basic structure of the power grid scheduling automation system includes three major parts: the control center master station system, the factory station terminal (RTU) and the signal point channel. According to the different functions completed, this system can be divided into information acquisition and execution subsystem, information transmission subsystem, information processing subsystem and human-machine contact subsystem.
