Description

Technical Field

[0001] This invention belongs to the field of fire alarm systems, specifically relating to a fire alarm system and method for automatically binding device identifiers and geographical information. Background Technology

[0002] In existing technologies, automatic fire alarm systems are core facilities for building fire safety. Current technologies are mainly divided into two categories: traditional wired fire alarm systems and stand-alone wireless fire alarm systems. Both have significant technical shortcomings and cannot meet the needs of renovation, expansion, and intelligent upgrades in complex scenarios such as old buildings, historical buildings, and temporary buildings: 1. Traditional wired systems: Compliant with GB50116 fire alarm standards, offering strong reliability and linkage capabilities, but suffer from complex wiring construction, high costs, long cycles, damage to existing decorations, easy aging of lines, and inflexible addition or removal of alarm points. They are unsuitable for building scenarios without pre-buried conduits or where construction is difficult; 2. Stand-alone wireless systems: Flexible deployment, but with four major drawbacks: 1. System fragmentation: Most systems use proprietary protocols, making it difficult to deeply integrate with existing wired alarm control panels and fire alarm control systems. This does not meet the centralized monitoring requirements of the GB16806 standard, resulting in information silos. 2. Unreliable communication: Star / point-to-point networks are susceptible to attenuation due to obstruction, and Mesh self-organizing network technology cannot be stably integrated and managed with wired systems. Third, cumbersome operation and maintenance: The physical address of the equipment is not related to the logical location of the fire protection system. The location information needs to be manually coded and entered one by one, which is prone to errors and inefficient. IV. Difficulty in reusing existing equipment: It is incompatible with existing wired front-end equipment, and the transformation requires complete replacement or dual-system parallel operation, which is costly and results in system fragmentation. Therefore, existing technologies lack a fire alarm solution that can deeply integrate the high reliability of wired systems with the flexibility of wireless systems, enabling unified access, automatic configuration, highly reliable communication, and convenient operation and maintenance for heterogeneous devices.

[0003] This invention seeks to mitigate or at least alleviate such problems or defects by providing new or otherwise improved fire alarm systems. Summary of the Invention

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a fire alarm system and method for automatically binding device identification and geographic information; To achieve the above objectives, the present invention provides a fire alarm system that automatically binds device identifiers and geographic information, comprising a fire alarm controller, at least one wired alarm loop, at least one wireless mesh network, several wired alarm terminals, and several wireless alarm terminals. The fire alarm controller integrates at least one wired loop interface and at least one wireless communication module. It also integrates a 4G communication module for uploading alarm and fault information to a cloud management platform and receiving remote commands. The wired alarm loop is a two-bus loop, connecting the wired loop interface to several wired alarm terminals. Each wired alarm terminal is configured with a pre-set unique hardware address code. The wireless mesh network is built based on LoRa spread spectrum communication technology, operating in the 480-498MHz frequency band. It supports multi-hop relay and network self-healing, automatically rerouting and restoring communication within 60 seconds in case of node failure or link interruption. The wireless mesh network connects the wireless communication module to several wireless alarm terminals. Each wireless alarm terminal has a built-in battery, LoRa module, and unique hardware identifier. The fire alarm controller is equipped with an integrated hardware encryption security unit, an automatic device information binding module, a multi-circuit fusion management unit, an accident data recording unit, and a backup power supply. The automatic device information binding module is used to receive and identify the hardware address code of the wired alarm terminal and the hardware identifier of the wireless alarm terminal, associate and bind the identified hardware address code or hardware identifier with the corresponding installation geographical information, and generate and store a unique logical identifier for the device containing the binding relationship. The accident data recording unit uses a power-loss protected read-only memory, and the first fire alarm record is permanently stored and cannot be tampered with. The multi-loop fusion management unit logically virtualizes the wired alarm loops and the wireless terminal group connected by the wireless Mesh network into multiple independent alarm zones, realizing unified monitoring and zone linkage; The fire alarm controller performs unified inspection, status monitoring, alarm reception, and linkage control on wired and wireless alarm terminals based on the unique logical identifier of the device.

[0005] As a further improvement of the present invention, the device information automatic binding module executes the SHA-256 irreversible hash algorithm through the hardware encryption security unit, and combines the hardware address code / hardware identifier, device type information and installation geographical information to generate a globally unique UUID as the unique logical identifier of the device.

[0006] As a further improvement of the present invention, the wireless alarm terminal has three working modes: deep sleep, periodic wake-up, and event triggering. In the non-alarm state, the wireless alarm terminal is in deep sleep mode, the LoRa module works in Class A power saving mode, and the deep sleep static current is ≤10μA.

[0008] As a further improvement of the present invention, the wireless mesh network has a self-healing function, and the network self-healing time is ≤60 seconds. When a node fails or a communication link is interrupted, the network automatically reselects a route and restores communication within 60 seconds.

[0009] As a further improvement of the present invention, the accident data recording unit is equipped with a digital signature module to digitally sign system alarm events, fault events, and operation logs to prevent the records from being tampered with, and the recorded data includes the corresponding device's unique logical identifier and timestamp information.

[0010] As a further improvement of the present invention, the backup power supply is a valve-regulated sealed lead-acid battery or a lithium thionyl chloride battery pack, and the wireless alarm terminal adopts an ER14505 type 2.4Ah lithium thionyl chloride battery.

[0011] As a further improvement of the present invention, the wireless alarm terminal is an independent point-type smoke detector, an independent point-type heat detector, an independent manual fire alarm button, or an independent fire sound and light alarm.

[0012] Another technical problem to be solved by this invention is a method for automatically binding device identifiers and geographic information, comprising the following steps: S1: System initialization, the fire alarm controller starts wired loop scanning and wireless Mesh network; S2: The controller identifies and obtains the hardware address codes of all online wired alarm terminals, as well as the hardware identifiers of all wireless alarm terminals that have joined the wireless Mesh network. S3: Through the controller's human-machine interface, enter the corresponding structured installation geographic information for each identified wired or wireless alarm terminal; S4: The SHA-256 irreversible hash algorithm is executed through the hardware encryption security unit of the fire alarm controller. With the hardware address code or hardware identifier, device type code and installation geographical information as input, a globally unique UUID is calculated and generated. The UUID and binding relationship are stored as the unique logical identifier of the device to achieve accurate fire alarm location within ≤3 seconds. S5: The controller performs unified management, monitoring and alarm processing on all alarm terminals based on the unique logical identifier of the device, with a cycle of 60 seconds.

[0013] As a further improvement of the present invention, the wireless alarm terminal wakes up once every 5 minutes, returns to deep sleep mode after completing the status report, and wakes up immediately to send an alarm signal when a fire alarm event is triggered.

[0014] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: 1. The fire alarm system and method for automatically binding device identifiers and geographic information of the present invention are easy to deploy: the hardware identifiers are ready to use upon installation, the hardware address codes are automatically recognized, eliminating the need for manual coding and location entry, reducing the complexity of construction and debugging, and improving deployment efficiency by more than 80%. 2.

With the help of a dedicated battery, it can achieve a battery life of more than 3 years, reducing maintenance costs. 6.

Device discovery: The controller automatically scans wired loops and reads the address codes and device types of all online hardware; after power-on, the hardware identifier automatically joins the Mesh network, registers with the controller, and reports the hardware identifier. 3. Geographic Information Input: Through the controller's human-machine interface, maintenance personnel input the structured installation location for each terminal, such as "Building A - 5th Floor - Room 503 - Smoke Detector"; 4. UUID generation: Using the SHA-256 hash algorithm, a globally unique UUID is generated by calculating the hardware identifier, device type code, and geographic information, such as 550e8400-e29b-41d4-a716-446655440000. This UUID is permanently stored as the terminal's unique logical identifier. 5. Formal Network Access: The controller performs a 60-second inspection of all terminals and displays the device location and status on the interface in the form of a map / list.

[0021] 3.

[0022] 4. Hardware identification power consumption management (corresponding to) Figure 4 ) Hardware identification adopts a three-level working mode: 1. Deep Sleep: In non-alarm state, static current ≤10μA, maintaining the sensor's minimum monitoring level; 2. Periodic wake-up: Wakes up every 5 minutes to report battery voltage and online status, then immediately returns to hibernation; 3. Event Trigger: Upon detecting a fire alarm / manual alarm, immediately wake up and send an alarm signal, then return to sleep mode after completion.

[0023] This strategy, combined with the ER14505 battery, achieves a hardware-marked battery life of over 3 years.

[0024] 5. Network self-healing and alarm linkage 1. Network self-healing: When a LoRaMesh network node fails / the link is interrupted, it automatically reselects the route within 60 seconds. The wired and wireless networks are physically and logically independent and serve as backups for each other. 2. Alarm linkage: After a fire alarm is triggered, the controller will resolve the UUID location of the device and initiate linkage within ≤3 seconds; the typical self-healing time of the LoRaMesh network is <60 seconds; and activate linkage devices such as audible and visual alarms, smoke exhaust valves, and audible and visual sirens, while simultaneously uploading data to the cloud management platform via the 4G module; 3. The deep sleep current of the wireless terminal is ≤10μA, and it is woken up for inspection every 5 minutes. With the ER14505 battery, it can achieve a battery life of more than 3 years.

[0025] 6.

Step 3: For each identified wired or wireless alarm terminal, obtain its corresponding installation geographical information; Step 4: Associate the hardware address code or hardware identifier of each alarm terminal with its corresponding installation geographical information to generate and store the terminal's unique logical identifier. Step 5: Based on the unique logical identifier of the device, the controller performs unified management, monitoring and alarm processing for all alarm terminals. In summary, wireless terminals are ready to use immediately without wiring, and wired terminals are automatically identified and bound to geographic information through device identification. This completely eliminates the tedious manual coding and location entry work of traditional wireless systems, greatly reducing the complexity of construction and debugging, improving deployment efficiency, and enabling convenient deployment and highly automated configuration.

[0026] By combining the reliability of wired systems with the flexibility of wireless systems, unified access, seamless management, and collaborative linkage of heterogeneous alarm terminals are achieved on a single controller platform. This solves the problem of system fragmentation, facilitates centralized monitoring and emergency command, and achieves the effects of integration, unification, and efficient management.
