1.2 System Architecture
1.3 System advantages
There are numerous on-site communication systems, making scheduling and command convenient. The basic communication systems are numerous and operate relatively independently; Integrating communication systems to interconnect communication methods; Smooth switching during emergency response.
High degree of informationization in emergency linkage: when an emergency event is triggered, the linkage processing mechanism is perfect; Customizable disposal approval process; Flexible alarm linkage rules; The process and outcome of emergency events are recorded.
Intuitive scheduling and clear command experience: visual video linkage on-site; Visual representation of alarm information and on-site video resource deployment; Voice, data, and video are displayed in one interface.
Centralized dispatching command: the unified dispatching command of administrative telephone, dispatching telephone, wireless telephone, public address broadcasting terminal, 4G/5G individual terminal and cluster intercom terminal is realized through the integrated dispatching software on the dispatching console.
One click alarm notification: In daily and emergency situations, alarm information and notifications can be broadcasted through the alarm notification function, SMS or voice.
Security monitoring linkage alarm: Based on the alarm information from the upper platform, SMS notifications or voice broadcasts (alarm information) can be automatically sent to relevant personnel. The cameras at the alarm points can be linked to view the on-site situation in real time, and personnel in the area can be notified to evacuate through the broadcasting system.
1.4 Construction goals of integrated communication system
ü Build a converged communication system that integrates wired, wireless, broadcast, and independent decentralized security subsystems into the converged communication system. Through the scheduling center's converged communication system, resource sharing, collaborative linkage, and unity among various linkage modules can be achieved.
ü Rich communication methods, supporting multiple interfaces such as E1, FXO, SIP, etc., to connect with operator PSTN, administrative telephone system, dispatch telephone system, broadcasting system, wireless cluster system, etc.
ü Establish a sound dispatch and communication system, by collecting the contact information, technical background, and other relevant information of various dispatch and rescue comprehensive fire rescue teams, professional dispatch and rescue teams, dispatch volunteer teams, and dispatch management expert teams, etc., and calling and contacting them with one click through the dispatch center.
ü The integrated docking monitoring system provides multi-dimensional data support and guarantee for the command and dispatch of the dispatch center by quickly viewing the equipment and facilities, operating status, data detection, alarm status, and security monitoring of the entire site through the control platform.
ü Create a fast alarm channel, where each area can call the dispatch center through explosion-proof telephones, handheld intercoms, public address broadcasting alarms, or through passive dry nodes such as fire protection, manual alarms, gas alarms, etc. with one click alarm to the dispatch center. The control platform of the dispatch center emits sound, light, and alarm information pop-up reminders, and dispatch personnel can achieve one click alarm reception and dispatch communication.
ü Realize scheduling data linkage, automatically wake up multi-dimensional information data such as alarm location (already located), alarm type, alarm time, video surveillance, and contact terminals by pushing alarm information to the scheduling center, and improve the response efficiency of dispatchers in emergency situations.
ü Backup emergency contact data, achieve centralized recording of explosion-proof telephones, handheld intercoms, and loudspeakers on different terminals, and record alarm time, alarm type, alarm time, alarm personnel, telephone records, and video records. All operation logs support backtracking queries.
ü The over limit alarm information pushed by the upper platform or system is fed back to the integrated communication system, and according to the pre-set processing flow, such as SMS group sending, voice broadcasting, regional broadcasting, audio and video conferences, the corresponding emergency team is commanded to handle it.
1.5 Introduction to Application Scenarios of Integrated Communication Scheduling System
1. 5.1 Application scenarios for daily command and dispatch
Daily command and dispatch mainly include basic voice dispatch modules to meet daily operational needs. On the backend platform, it is necessary to interface with other systems in the factory area, such as video surveillance, wireless intercom groups, 4G/5G terminals, administrative telephones, dispatch telephones, video conferencing, broadcasting systems, etc. The daily operational functions are as follows:
1.5.2 Emergency Dispatch Application Scenarios
