Description

Technical Field

[0001] The present invention relates to the field of fire protection, and in particular to a remote monitoring system for a traditional fire protection host. Background Art

[0002] Amid the development of smart cities and smart firefighting, the intelligent upgrade of firefighting facilities has become a key trend in public safety. Traditional firefighting systems, due to their limited technical architecture, are difficult to integrate into the smart firefighting ecosystem. Technological transformation is urgently needed to enable data interoperability and remote monitoring.

[0003] Traditional fire control hosts, as the core equipment of building fire protection systems, generally adopt a closed architecture and have the following pain points: single communication interface: most devices only support local RS485 or CAN bus communication and cannot directly access the Internet; data island problem: fire control host protocols of different manufacturers are not unified, and data is difficult to centrally manage; lack of real-time monitoring: relying on manual inspections, fire alarm or fault information cannot be reported in a timely manner, and there is a risk of delayed response; high operation and maintenance costs: on-site debugging and troubleshooting require manual presence, especially in large building complexes, where operation and maintenance efficiency is low.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0031] The embodiment of the present invention provides a traditional fire host remote monitoring system, the system hardware components include:

[0032] Communication board:

[0033] Interface: Adapt to the traditional fire host expansion slot (such as RS485 / RS232 interface); the interface adaptation structure between the fire host expansion slot and the communication board, including pin definition, electrical characteristics and mechanical dimensions;

[0034] Function: Collect host internal data (fire alarm signal, equipment status, fault code, etc.) and encapsulate it in GB26875.3-2011 protocol format;

[0035] User information transmission device:

[0036] Communication module: built-in 4G / 5G full network module, supporting RJ45 communication;

[0037] Protocol conversion: Upload the GB26875.3-2011 protocol data output by the communication board to the cloud server via the TCP / IP protocol.

[0038] In this embodiment, the data processing flow of the system is as follows:

[0039] Data acquisition: The communication board is connected to the fire host through the expansion slot to read register data (such as fire alarm address code and equipment status bit) in real time;

[0040] Protocol encapsulation: The communication board encapsulates the original data into a standardized data packet containing device ID, data type, and value according to the GB26875.3-2011 protocol specification;

[0041] Remote transmission: After receiving the data packet, the user information transmission device sends it to the monitoring center server through the network;

[0042] Parsing and display: The server parses the data packet, generates a visual interface (such as an electronic map with fire alarm locations and a device status list), and supports API interfaces for third-party platforms to call.

[0043] In this embodiment, the GB26875.3-2011 protocol is adapted:

[0044] Data frame structure: Comply with the "Communication protocol between monitoring center and user information transmission device" in the standard, assemble the device address, function code (such as 0x01 for fire alarm data), data body and check code into a standard data packet;

[0045] Heartbeat mechanism: The user information transmission device sends a heartbeat packet to the server every 10 seconds. The server monitors the online status of the device in real time and can trigger an alarm if the device is offline for more than 10 seconds. Considering the weak 4G signal in some areas, the offline monitoring interval can be appropriately increased.

[0046] In this embodiment, the server-side parsing logic:

[0047] Structured processing: convert the received binary data into JSON format;

[0048] Alarm classification: Automatically distinguish alarm levels (fire alarm, fault, supervision signal) according to data type, and fire alarm information is pushed to the on-duty personnel’s mobile phone APP first;

[0049] The data types mainly include the following:

[0050] 1. Fire alarm: Direct fire detection equipment, such as smoke detectors, and hand alarms will report such data;

[0051] 2. Heartbeat packet: maintains online equipment. If there is a network failure or power outage, the heartbeat packet will stop and relevant personnel need to deal with it immediately, otherwise the system will not be able to monitor fire information;

[0052] 3. Sensor failure: When various sensors such as smoke detectors, hand alarms, sound and light alarms, fire broadcasts, sprinkler pumps, etc. are damaged and need to be repaired, the data will be reported by the user, and maintenance personnel will need to intervene;

[0053] 4. Supervision: Some auxiliary firefighting equipment uploads analog values, but the values ​​are not within the threshold range. For example, the pressure in the fire water system is too low / too high, and the fire shutter door does not rise to the highest / lowest level when it is activated. The on-duty personnel need to troubleshoot the fault;

[0054] Historical data storage: A high-performance distributed database is used to store at least one year of equipment operation data, supporting trend analysis and fault tracing.

[0055] In this embodiment, the GB26875.3-2011 protocol engine: integrates the protocol parsing and encapsulation engine in the board firmware to ensure that the data format complies with the national standard; the real-time data synchronization algorithm: combines the data request / response mechanism to achieve a data transmission success rate of ≥99.9% and an average delay of ≤100ms.

[0056] In this embodiment, the real-time monitoring system includes a complete remote monitoring architecture including a user information transmission device, a server, and a client, and realizes closed-loop management of data collection, transmission, analysis, and display.

[0057] It should be noted that, in this document, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.
