[0054] The field control area includes multiple wireless emergency broadcast alarm terminals, a speaker d, an AI camera, and a solar power supply device. Among them, each wireless emergency broadcast alarm terminal is connected to the speaker d, the AI camera, and the solar power supply device.

[0055] In the present invention, a signal transmission mode among a mobile terminal, an emergency command center, a central control room cabinet, and multiple broadcast zones is adopted from among a wireless DMR protocol, a wireless PDT protocol, and a wireless TETRA protocol for information interaction. While realizing functions such as linkage alarm, daily voice broadcast and intercom, alarm broadcast, and emergency voice broadcast, it can solve the defect of complex wiring caused by transmission cables in the current wired connection type sound amplification intercom system, reduce the system construction cost, shorten the system construction cycle, and also improve the system's ability to adapt to various complex scenarios.

[0056] Specifically, in the emergency command center, a call host uses a signal transmission mode among a wireless DMR protocol, a wireless PDT protocol, and a wireless TETRA protocol to communicate and connect with a wireless walkie-talkie, an alarm gateway, a call extension a, a call extension b, and a wireless emergency broadcast alarm terminal respectively for wireless communication.

[0057] When the system is running normally, the call host can initiate a daily voice broadcast to one or more broadcast zones at any time or regularly. The call host can initiate a point call to each call extension a, each call extension b, each wireless emergency broadcast alarm terminal, the alarm gateway, a constant voltage power amplifier, and a speaker at any time for daily voice broadcast. The call host responds to the alarm broadcast initiated by the alarm gateway and displays the alarm area name and number.

[0058] In case of an emergency, the call host can interrupt all alarm broadcasts, daily voice broadcasts, and recording broadcasts in the system and initiate an emergency voice broadcast to each broadcast zone.

[0059] The wireless walkie-talkie uses a signal transmission mode among a wireless DMR protocol, a wireless PDT protocol, and a wireless TETRA protocol to communicate and connect with the call host, the alarm gateway, the call extension a, the call extension b, and the wireless emergency broadcast alarm terminal respectively for wireless communication.

[0060] When the system is running normally, the wireless walkie-talkie can issue a daily voice broadcast to each broadcast zone, initiate a point call to each call extension a, each call extension b, each wireless emergency broadcast alarm terminal, the alarm gateway, the constant voltage power amplifier, the speaker, or the call host in the system for daily voice broadcast, and respond to the alarm broadcast initiated by the alarm gateway.

[0061] Specifically, in the central control room cabinet, the alarm gateway uses a signal transmission mode among a wireless DMR protocol, a wireless PDT protocol, and a wireless TETRA protocol to communicate wirelessly with the wireless walkie-talkie, the call host, the call extension a, the call extension b, and the wireless emergency broadcast alarm terminal respectively.

[0062] The operation and maintenance data and parameters within the server of the computer client real-time configuration management system are configured remotely for the call host, each call extension a, each call extension b, the alarm gateway, and the point call, area call, and full call numbers and output volumes of each wireless emergency broadcast alarm terminal.

[0063] The computer client is connected to the alarm gateway through the system server, and wirelessly communicates with the wireless intercom, call host, call extension a, call extension b, and wireless emergency broadcast alarm terminal respectively through the alarm gateway and one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0064] The computer client queries the online / offline status of the call host, each call extension a, each call extension b, the wireless intercom, the alarm gateway, and the wireless emergency broadcast alarm terminal in real time through the system server, supports the hard disk storage and query function of historical records, and supports the position, device number editing, and status display functions in the GIS map or CAD floor plan.

[0065] The system server records the generated daily voice broadcasts, recorded broadcasts, alarm broadcasts, and emergency voice broadcasts, and supports querying and playback by the computer client. Among them, the recording storage time is not less than 12 months.

[0066] When the fire alarm system issues an alarm, the fire alarm system automatically triggers the alarm gateway to send alarm broadcasts to the constant voltage power amplifier and speakers, and each broadcast zone according to the alarm plan. The fire alarm system uploads the alarm records to the system server through the alarm gateway, and the alarm gateway can also manually initiate the alarm broadcast function.

[0067] Among them, the sound content of the alarm broadcast can be changed, the alarm records can be uploaded to the system server for storage, and the alarm information can trigger pop-up windows and sound prompts on the computer client.

[0068] Both the converged communication system and the dispatching / administrative telephone system are connected to the FXO analog telephone voice gateway, then connected to the constant voltage power amplifier and speakers through the alarm gateway, and wirelessly communicate with the wireless intercom, call host, call extension a, call extension b, and wireless emergency broadcast alarm terminal respectively through the alarm gateway and one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0069] The converged communication system and the dispatching / administrative telephone system can respectively send daily voice broadcasts to the constant voltage power amplifier and speakers, and each broadcast zone through the FXO analog telephone voice gateway.

[0070] Specifically, the mobile device communicates with the wireless voice gateway in the cabinet of the central control room through the 4G / 5G network, and respectively conducts wireless communication with the wireless walkie-talkie, call host, call extension a, call extension b, and wireless emergency broadcast alarm terminal through the alarm gateway and one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0071] The mobile device issues daily voice broadcasts to the constant-voltage power amplifier, speakers, and each broadcast zone through the wireless voice gateway and the alarm gateway, receives and displays the online / offline status information of the call host, each call extension a, each call extension b, the wireless walkie-talkie, and the wireless emergency broadcast alarm terminal, and synchronously receives the alarm broadcast information initiated by the alarm gateway.

[0072] Specifically, in the central control room, call extension a is connected to speaker b, and call extension a respectively conducts wireless communication with the wireless walkie-talkie, call host, other call extensions, and wireless emergency broadcast alarm terminal through one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0073] Since each call extension a belongs to a broadcast zone, call extension a can initiate daily point-to-point call broadcasts and intercoms to the call host, wireless walkie-talkie, or call extension b in the same broadcast zone, and initiate point-to-point call broadcasts or daily voice broadcasts to the wireless emergency broadcast alarm terminal in the same broadcast zone.

[0074] Specifically, in the on-site control room, call extension b is connected to speaker c, and call extension b respectively conducts wireless communication with the wireless walkie-talkie, call host, other call extensions, and wireless emergency broadcast alarm terminal through one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0075] Since each call extension b belongs to a broadcast zone, call extension b can initiate daily point-to-point call broadcasts and intercoms to the call host, wireless walkie-talkie, or call extension a in the same broadcast zone, and initiate point-to-point call broadcasts or daily voice broadcasts to the wireless emergency broadcast alarm terminal in the same broadcast zone.

[0076] Specifically, in the on-site control area, the wireless emergency broadcast alarm terminal respectively conducts wireless communication with the wireless walkie-talkie, call host, call extension a, call extension b, and alarm gateway through one of the signal transmission methods of the wireless DMR protocol, wireless PDT protocol, and wireless TETRA protocol.

[0077] Since each wireless emergency broadcast alarm terminal belongs to a broadcast zone, the wireless emergency broadcast alarm terminal can respond to the call host, wireless intercom, or call extension a and call extension b in the same broadcast zone at any time to initiate point call or zone call for daily broadcast, respond to the alarm broadcast issued by the alarm gateway at any time, and respond to the emergency voice broadcast issued by the call host at any time.

[0078] Furthermore, the wireless emergency broadcast alarm terminal includes an alarm input interface. When the AI camera detects smoke or fire, it outputs a linkage signal and inputs it into the alarm input interface, triggering call extension a, call extension b, speaker b, speaker c, wireless emergency broadcast alarm terminal, and call host in the same broadcast zone to issue an alarm broadcast.

[0079] Furthermore, the wireless emergency broadcast alarm terminal can be powered by a solar power supply device or a UPS.

[0080] In the present invention, the system broadcast is divided into emergency voice broadcast, alarm broadcast, daily voice broadcast, and recording broadcast. The priority of the emergency voice broadcast is level 1 (highest), the priority of the alarm broadcast is level 2, and the priorities of the daily voice broadcast and recording broadcast are level 3 (lowest). High-priority broadcasts can unconditionally interrupt low-priority broadcasts, enabling the system to respond to high-priority broadcasts.

[0081] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, or even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
