[0002] Currently, there are two channels for fire alarms. The first is the fire alarm broadcast system, which includes fire alarm message input, fire alarm controller, power amplifier, and fire loudspeakers. When a fire occurs, the fire information is reported to the fire department via the 119 emergency number. The fire department then inputs the fire information into the fire alarm broadcast system for broadcast.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Currently, fire broadcasting systems and emergency broadcasting systems operate independently without a coordinated operation mechanism. This application aims to address the problem of how to utilize the emergency broadcasting platform to generate fire messages, use the emergency broadcasting system's transmission coverage network to send messages through multiple channels, and utilize the fire loudspeakers of the fire broadcasting system to broadcast the messages, thereby enabling coordinated operation between the emergency broadcasting system and the fire broadcasting system.

[0053] To address the message source issue in the fire broadcast system, it is proposed to utilize the emergency broadcast system to generate fire-related messages as the message source for the fire broadcast system. This requires connecting the emergency broadcast system to the fire broadcast system.

[0054] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0055] Example 1:

[0056] Figure 1This is a schematic diagram of the interface architecture between the emergency broadcasting system and the fire broadcasting system provided in Embodiment 1 of the present invention.

[0057] Reference Figure 1 To connect the emergency broadcast system to the fire broadcast system, the emergency broadcast platform and transmission coverage network components must be retained at the emergency broadcast system end, while the emergency broadcast terminal is removed. Through the emergency broadcast access device, the message receiving and processing functions of the emergency broadcast terminal and the fire broadcast message input and fire broadcast control functions of the fire broadcast system are integrated. The device is directly connected to the power amplifier of the fire broadcast system to realize the connection between the emergency broadcast system and the fire broadcast system.

[0058] The emergency broadcast access device includes modules such as a main controller, an embedded multi-channel message access card, a fire message access card, security services, and message management.

[0059] Main controller: Used to deploy service software. The main functions of the software are to interface with the upstream transmission and coverage network, interface with the downstream fire broadcast controller, and to control the process of message access, parsing, signature verification, adaptation, encapsulation, and transmission.

[0060] Embedded multi-channel message access card: used to receive emergency broadcast transmission instructions from the transmission coverage network and perform deblocking, signature verification, protocol parsing and other processing, including the reception and processing of FM signals, TS streams and IP signals.

[0061] Fire message access card: Used to receive emergency broadcast messages from embedded multi-channel message access cards, perform protocol adaptation, re-encapsulation, and distribution of the messages.

[0062] Protocol adaptation involves converting emergency broadcast messages into corresponding channel (RDS, TS, or IP) programs and transmission coverage instructions according to the data exchange protocol agreed upon by the emergency broadcast system and the fire broadcast system. Re-encapsulation involves encapsulating the results of protocol adaptation according to the data format required by the fire broadcast controller.

[0063] Security services: Verify and confirm received emergency broadcast message instructions, and protect sent emergency broadcast message instructions with signatures to ensure secure instruction transmission.

[0064] Message Management: Saves records of the transmission status of emergency broadcast message commands for future review.

[0065] In summary, the emergency broadcast access device receives emergency broadcast transmission instructions from wired / terrestrial / FM / IP channels from the transmission coverage network, performs parsing, signature verification, adaptation, and re-encapsulation, and then transmits them to the fire broadcast controller, which is responsible for distributing and broadcasting emergency broadcast messages within the fire broadcast system.

[0066] The key component of the emergency broadcast access device is the embedded multi-channel message access card, which is the foundation for receiving, processing, and broadcasting multi-channel emergency broadcast transmission instructions.

[0067] The embedded multi-channel message access card is embedded in the emergency broadcast access device. Upstream, it interfaces with the transmission coverage network to receive emergency broadcast transmission instructions from the transmission coverage network and perform deblocking, signature verification, and protocol parsing processing. Downstream, it interfaces with the fire message access card to ensure that real, legal, and complete emergency broadcast messages are transmitted to the fire broadcast system.

[0068] Depackaging refers to unpacking the received emergency broadcast message data packets according to different encapsulation formats such as wired / terrestrial / FM / IP channels.

[0069] Signature verification refers to verifying the authenticity of the digital certificate parsed from the message data packet to ensure the authenticity and reliability of the message source.

[0070] Protocol parsing refers to verifying whether the message parsed from the message data packet conforms to the data format required by the wired / terrestrial / FM / IP channels, so as to ensure the legality and integrity of the message.

[0071] Embedded multi-channel message access cards can receive messages through both hardware and software methods.

[0072] On the hardware side, it receives external messages through an interface, such as... Figure 2 As shown, the external interface description is referenced in Table 1:

[0073] Table 1

[0074]

[0075] In terms of software, external FM signals, TS streams, and IP signals are received through wired / terrestrial / FM / IP channels respectively.

[0076] The embedded multi-channel message access card processes the received messages separately. The processing procedures for wired / terrestrial / FM / IP messages are basically the same, but the data formats of each channel are not entirely the same.
