It is the core processing equipment of the whole system. All terminals can be registered through sip or connected to the command and dispatching system through the fusion switch equipment to accept unified management, monitoring and deployment

2) the recording and video server

is responsible for the classified recording and storage of audio, video, pictures, text, geographical location and other data generated in the process of system scheduling, and can conduct combined query according to the playback requirements

3) trunking intercom off

trunking intercom off can integrate the intercom trunking system with the IP broadcast intercom integrated dispatching system, which is compatible with mainstream intercom handsets and on-board electricity, and connect the original intercom equipment to the dispatching system. Users can easily call the intercom or use the intercom to dial, The system supports traditional PSTN lines and sip based VoIP lines

dispatching center

1) command and dispatching console

as a tool for the dispatcher to interact with the dispatching system. The notification, intercom, status monitoring, etc. of various terminals under the system can be realized by installing the scheduling system client

2) visual pager

can call, two-way intercom, monitor/monitor, broadcast and shout to the host and extension in the management area

network coverage

1) it is provided by the public operator network with perfect coverage

using the 4G network of the operator, we can use the network channel with high bandwidth and high efficiency to carry all kinds of real-time data, audio and video data and other multimedia services in command and scheduling

2) special emergency

when an emergency occurs, public communication may be congested or paralyzed, and the existing public network can no longer be used to realize cluster intercom and command and scheduling. Especially when the special network cannot be covered, the regional special system can be built in the mobile command vehicle by using the portable special base station to realize the command and scheduling in the emergency area

work terminal

1) interphone

2) cluster scheduling single soldier terminal

3) IP phone

4) analog phone

video conference

4. Main functions

01 hierarchical management

according to the structure of the management department and the arrangement of work tasks, each unit can be divided into different work groups to realize hierarchical management, for example:

1 Bureau level command center: a first-class unit that can manage all other departments

2. Branch command center: secondary units can only manage their own departments, and cannot interfere with superior or parallel departments

3. Below the second level, groups can be divided according to the nature of work, such as 1 group, 2 groups, etc

02 intercom and call

support one key call, point call and group call. The number is stored corresponding to the name to realize fast speed dialing; The system supports local or wide area audio and video calls, one-way video, two-way video, etc; Support paging intercom; Support call group

all units and groups can carry out group intercom, single call, temporary call, predefined group call, multi group monitoring, etc. according to the actual working conditions, so as to realize flexible communication

03 group intercom

the staff are scattered. The staff of the same working group can be placed in a group as the default working group of the staff of the group, and the working hours are unified online

when the staff needs to talk with the same group to communicate the current situation, they can directly press the PTT button on the terminal to speak in the group, and the people in the same group can hear it

each department can set up a dispatcher, who can log in through the dispatching desk. The dispatcher can enter each working group at any time in the dispatcher to monitor the work of each working group

04 priority

the head or dispatcher of the Department sometimes needs to have intercom permission higher than that of other users, and can give priority to speaking in case of emergency

therefore, the head of each department can be set as a high priority user in the management platform, and other general staff can be set as a low priority user. High priority members can seize the voice rights of low priority users

in case of emergency and need to temporarily take over the group scheduling authority, the leader or dispatcher with higher priority can timely seize the voice rights of other users in the group, issue unified instructions and coordinate scheduling resources

05 temporary call

staff or dispatcher sometimes need to communicate with others alone, and do not want to be heard by other team members. At this time, the staff or dispatcher can select the user who needs to speak alone in the intercom terminal, initiate a call through the temporary call function, and establish a temporary group

speaking in a temporary group, only members of the temporary group can listen. As the name suggests, it can only be used to do single 1 stretching experiments

06 visual intercom, recording

mutual call and two-way visual intercom between management machines. Through the system, the call can be recorded, and the whole process of police handling and command and dispatching can be recorded, which is not only valuable empirical data, but also provide evidence for future troubleshooting

07 video linkage
