I. Overview and needs of safe cities

 

Program design: Ping An City is a very large and comprehensive management system. It not only needs to meet the requirements of public security management, urban management, traffic management, emergency command, but also the disaster warning and safety monitoring. The government's investment in the construction of a safe city video surveillance system is often only remote monitoring, and can not synchronize voice command and dispatch. In the event of a major incident or an emergency, the evidence can only be obtained afterwards, and the pre-emptive precautions and the remote deterrent control of the voice depreciation cannot be pre-broadcast. Only this two-way node IP network public broadcast transmitted over the TCP/IP protocol can meet this requirement. The two-way node IP network public broadcasting is attached to the very powerful network system inside the Public Security Bureau, thus linking the various monitoring points and the monitoring command center. According to the requirements of the city, the application of the two-way node IP network public broadcasting in the city is fully proved. The radio system is irreplaceable, technologically advanced, full-featured, reliable, and easy to use. Therefore, the two-way node IP network public broadcasting is the only choice for the safe city public address system. The complex application requirements of the city system.

 

 

 

Second, the role of two-way intercom in IPC public broadcasting in Safe City

 

Emergency help

 

When the public encounters an emergency, the emergency help signal is sent in time through a shortcut button on the network terminal, and the two-way intercom is initiated to contact the security center. When the rescuer sees the IP address, he knows which part of the area is happening. The operation is very simple and user-friendly, without wasting time, and there is no need to worry about the busy situation.

 

Monitoring broadcast: When the monitoring center monitors the incident to this point through the camera, the monitoring center can issue a warning to the monitoring point through the IP network broadcast, prompting the language to prevent the occurrence of a vicious event.

 

 

 

Third, the management platform

 

The platform of Ping An City's IP communication broadcasting system adopts a three-level cascade structure of the municipal bureau, branch office and police station. Each level of broadcast monitoring center has its own management platform and equipment. The system can be built on the internal network of the Public Security Bureau or designed using the WAN. Voice signals can be delivered to designated locations wherever there is a network. To use this system to help the public security department to control and fight crime more efficiently and accurately, thus ensuring the harmony, stability and development of the city.

 

The three-level management mode is as follows

 

(1) Public security sub-bureaus to the police stations;

 

(2) Each police station shall have a jurisdiction over the street;

 

(3) The Municipal Public Security Bureau broadcasts all or part of it.

 

 

 

Fourth, the safe city two-way intercom IP network public broadcasting function

 

110 alarm remote voice call and command

 

Use the safe city broadcast system with the monitoring system to use. That is, a monitoring point configures a broadcast point. In addition, in important places involving public safety, such as state organs, schools, banks, street communities, commercial prosperous areas, and complex road sections of public security, citizens are advised to talk about police and people. In order to enable the masses to encounter major emergencies in their daily lives, they can use this network to seek emergency assistance from the public security organs to realize two-way intercommunication between the police and the people.

 

Timed program play

 

Each network adapter of the IP network broadcast has a separate IP address, and can receive the personalized timed broadcast program of the server separately, and the timed play operation can also set the upload program on the network through the computer.

 

Audio real-time broadcast

 

IP broadcast program real-time broadcast function, can be: self-use radio, recorder deck, CD player, MP3 player, microphone and other programs real-time acquisition into a high-quality data stream is stored into the server, and can be broadcast to the specified time Network adapter for inserting external program broadcasts and broadcast notifications.

 

Public information release (emergency information, traffic information, natural disaster information, etc.)

 

One-click help, two-way intercom

 

In the important places or sections, police people can be connected to the intercom point. In the event of a major emergency in daily life, the citizens can use the network emergency help terminal to seek emergency assistance from the public security organs to realize the two-way conversation between the police and the police.

 

Two-way intercom can be realized between the terminal and the terminal, and between the computer and the terminal. When calling (intercom), you can directly input the address code of the called (intercom) terminal by using the remote control, or select the terminal address by pressing the button on the panel.

 

Monitoring linkage

 

When the monitoring center monitors the incident to the point through the camera, the monitoring center can issue a warning to the monitoring point through the IP network broadcast, prompting the language to prevent the occurrence of a malicious event.

 

Map linkage

 

Integration with various application systems is seamlessly connected to each application system through the management platform. It can realize the integration of the safe city monitoring system and various public security application systems, such as the 110 alarm system, geographic information system, GPS global satellite positioning system, and urban traffic management system.

 

Alarm and alarm light flashing synchronization

 

In the event of an emergency, an effective strategy can be adopted to notify each zone through audio and video linkage functions, and timely and effective solutions.

 

Real-time monitoring of intercom content

 

When there are suspicious objects and emergency squadrons in the monitoring video found by the branch office or each police station, the branch monitoring center or the police station can realize the emergency voice call to the monitoring point, and carry out the work of the crowd or the command site, and also for the suspicious objects;

 

The voice is shocked; at the same time, the monitoring center of the branch office or the monitoring center of the police station is equipped with a monitor speaker to monitor the speech or call of the duty staff in real time.

 

Alarm pre-busy transfer

 

One way alarm is forced to insert, and the external alarm (such as fire alarm) signal can automatically trigger the whole system to start and access the alarm broadcast, no need for human operation, and the N±1, N±N alarm function can be realized according to the preset. For example, when a voice intercom terminal in the monitoring center is talking, no answer or shutdown after the specified number of rings, it will be automatically transferred to the next voice intercom terminal of the monitoring center.
