Description

Technical Field

[0001] This utility model belongs to the field of smart building technology, and in particular relates to a multi-system collaborative intelligent public address system. Background Technology

[0002] As a comprehensive building that integrates transportation hub functions and commercial functions, TOD commercial buildings are characterized by large passenger flow, complex functional zoning, and frequent scene switching. This means that their public address system must meet multiple application needs, including daily operation, emergency evacuation, and routine information dissemination.

[0003] However, the public address systems currently widely used in TOD commercial buildings and similar complexes have significant problems: Firstly, their functionality is limited. Most existing public address systems only support basic audio playback functions, such as playing fixed audio content according to preset time slots or manual triggering, lacking intelligent linkage mechanisms with fire protection systems. In emergencies such as fires, they cannot automatically acquire fire alarm signals and switch to emergency broadcast mode, still relying on manual switching. Due to the reaction time lag and risk of operational errors in manual operation, evacuation opportunities are easily delayed, failing to meet the timeliness requirements of instructions in emergency scenarios. Secondly, their multi-system integration and collaboration capabilities are insufficient. In TOD commercial building scenarios, in addition to the public address system, access control systems are used to manage personnel access permissions, and IoT devices are used to collect environmental and operational data. These systems should operate collaboratively in emergency situations, but the existing public address system lacks a deep integration architecture and data interaction with access control systems and IoT devices, making it difficult to achieve multi-system collaborative response in emergency situations and reducing the overall effectiveness of TOD commercial buildings in responding to emergencies. Utility Model Content

It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

Figure 1 As shown, it includes a fire control room subsystem, a broadcast terminal subsystem on each floor, a service desk system on the first floor, an access control subsystem, and a fire alarm system.

[0023] Specifically, the fire control room subsystem is located in the fire control room and includes fiber optic patch panels, core switches, intelligent fire protection IoT host, paging microphones and zone keypads, digital tuners, integrated players, power sequencers, network monitoring speakers, intelligent network broadcast host, and UPS power supplies.

[0028] The power sequencer is connected to the intelligent network broadcast host via a power cord. In this embodiment, the power sequencer can automatically or manually control the power supply of 16 controlled devices to turn on or off in sequence, effectively managing and controlling various electrical devices in a unified manner and avoiding human error. At the same time, it reduces the impact of electrical devices on the power grid during switching and avoids the impact of induced current on the electrical devices, ensuring the stability of the entire power system.

[0029] The network monitoring speaker is connected to the core switch via a network cable. The network monitoring speaker is a networked speaker system that integrates a networked terminal processor with a high-fidelity speaker. In this embodiment, it is used to receive digital audio signals and achieve high-fidelity reproduction; it features a dual-network interface redundancy design, allowing it to operate across network segments.

[0030] In addition, the fire control room subsystem also includes a computer and a card issuer. The computer serves as the control workstation of the fire control room and is connected to the core switch via a network cable. The card issuer is connected to the computer via a network cable and can perform operations such as reading cards, writing cards, authorizing cards, and formatting cards. The card types supported in this embodiment include ID cards, Mifare cards, second- and third-generation ID cards (serial numbers), ordinary CPU cards, and national cryptographic CPU cards.

[0031] Furthermore, the broadcast terminal subsystems on each floor are connected to fiber optic distribution frames via optical fibers.

[0032] Specifically, the broadcast terminal subsystem is set up on each floor, including several equipment switches, several ceiling speakers, and several network amplifiers. In this embodiment, the equipment switches are set up in the low-voltage room on each floor; the ceiling speakers are set up in the public corridors, atriums, shop entrances, etc. on each floor; and the network amplifiers are set up in the low-voltage room or ceiling equipment boxes on each floor.

[0033] Several ceiling speakers are connected to the network amplifier via RVVP2*1.0 cables. The network amplifier adopts a dual network interface redundancy design, supports 100M / 10M adaptive TCP / IP network transmission protocol, and supports cross-network segment operation.

[0036] Furthermore, the first-floor service counter subsystem is connected to the fiber optic patch panel via fiber optic cable.

[0037] Specifically, the first-floor service desk subsystem is located at the first-floor service desk and includes a device switch, a network paging microphone, and a service desk host.

[0038] The network paging microphone and the service desk host are connected to the equipment switch of the service desk subsystem on the first floor via Category 6 network cables. The equipment switch of the service desk subsystem on the first floor is connected to the fiber optic patch panel via fiber optic cables.

[0039] Furthermore, the access control subsystem is connected to a fiber optic patch panel via optical fiber.

[0040] Specifically, the access control subsystem includes access control for evacuation routes in the fire control room and other access control systems in the low-voltage equipment room, domestic pump room, fire pump room, and fire water tank room, including dual-door controllers, card readers, electric locks, and facial recognition access control integrated machines.

[0041] The dual-door controllers are connected to the UPS power supply via power lines. The evacuation route access control is powered by the independent mains power from the fire control room, while the other access control systems are powered by the UPS in the fire control room.

[0042] The dual-door controller connects to the intelligent fire protection IoT host via RVV2*1.5. In this embodiment, the core functions of the dual-door controller include access control and security linkage control. It has a storage capacity of 100,000 cards and 300,000 records, a 32-bit processor, and dual communication interfaces of RS485 and Wiegand.

[0043] The dual-door controller is connected to the card reader via RVVP6*1.0. In this embodiment, the card reader has a reading frequency of 13.56MHz and can identify Mifare card number, Mifare card content, CPU card number, etc.

[0044] The dual-door controller connects to the electric lock via RVV2*1.5. The electric lock is the actuator of the access control subsystem, i.e., the door opening and closing mechanism.

[0045] The dual-door controller connects to the face recognition access control system via RVV2*1.0. The face recognition access control system integrates face recognition technology to achieve integrated access control and management. The face recognition technology is implemented using existing technology.

[0046] In this embodiment, remote control of access control switches and remote opening of electric locks in evacuation routes can be achieved. Specifically, the intelligent fire protection IoT host outputs a passive dry contact signal via RVV2×1.5 The shielded wire is directly connected to the input terminal of the dual-door controller; when the signal is triggered, the dual-door controller immediately cuts off the power supply to the lock, the electric lock enters the power-off release state, and the door remains open.

[0047] In addition, the access control subsystem located in the fire control room has its dual-door controller connected to the core switch of the fire control room subsystem via a Category 6 network cable.

[0048] The access control subsystem installed in the low-voltage equipment room, domestic pump room, fire pump room, and fire water tank room also includes an equipment switch. The other end of each of the dual door controllers is connected to the equipment switch of the access control subsystem via a Category 6 network cable. The equipment switch of the access control subsystem is connected to the fiber optic distribution frame via optical fiber.

[0049] Furthermore, the access control subsystem adopts a TCP / IP network-based system and is linked with the automatic fire alarm system. The fire alarm system connects to the intelligent fire protection IoT host via network signals.

[0050] In this embodiment, the working principle of the multi-system collaborative intelligent public address system is as follows: When the fire control room actively plays an audio source, the audio source signal is configured with zones through the intelligent network broadcast host, and then transmitted sequentially through the core switch, the equipment switches on each floor, and the network amplifier to the ceiling speaker, which then plays the audio source signal.

[0051] When the service desk on the first floor needs to make a paging announcement, it can either speak directly or play a stored audio source through the service desk host. The audio source signal is transmitted sequentially through the equipment switch and the core switch to the intelligent network broadcast host. The intelligent network broadcast host sets up the partitions and then transmits the signal sequentially through the core switch, the equipment switches on each floor, and the network amplifier to the ceiling speaker, which then plays the audio source signal.

[0052] In an emergency, when the fire alarm system detects a fire signal (such as an alarm from a smoke detector, heat detector, or a manual alarm button), the intelligent fire protection IoT host automatically sends a linkage signal to the broadcast system through preset logic, switching to emergency broadcast mode. The fire control room can also force a switch to emergency broadcast mode with a single button press at the first-floor service desk, ensuring that emergency instructions are broadcast with priority. Simultaneously, the intelligent fire protection IoT host outputs a signal to the dual-door controller, which, upon receiving this signal, automatically releases the locks on the relevant fire evacuation routes.

[0053] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
