Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, and in particular to an intelligent zone-controlled smart fire sprinkler system. Background Technology

[0002] In modern buildings, fire sprinkler systems are crucial fire safety facilities, enabling timely water spraying to extinguish fires and effectively reducing casualties and property damage. Existing fire sprinkler systems typically use glass bulb sprinklers, with several bulbs installed in designated areas within the building. Each sprinkler head contains a glass bulb filled with an organic solvent with a high coefficient of thermal expansion. At room temperature, the bulb's outer shell can withstand a certain amount of support, holding the sprinkler head's sealing gasket in place, thus ensuring good sealing performance. When a fire occurs, the ambient temperature rises sharply, causing the organic solvent to expand and shatter the glass bulb. The bulb seat and seals lose their support and are dislodged by the water flow, allowing water to spray out and automatically extinguish the fire in the area where the sprinkler head is located.

[0003] However, fire sprinkler systems using glass bulb sprinkler heads have several drawbacks: First, the sprinkler heads rely solely on sensing ambient temperature—a single fire signal—to control the glass bulb's breakage and thus activate the sprinkler head to spray water. This results in low accuracy and reliability, making the sprinkler heads prone to malfunctions in situations such as abnormally high ambient temperatures (e.g., heat dissipation from high-power equipment). Second, glass bulb sprinkler heads are purely mechanically controlled, with the sprinkler system and fire alarm system operating independently. The sprinkler system relies on the glass bulb's temperature sensing to spray water, while the fire alarm system uses smoke sensors and other monitoring devices to detect fires and issue alarms. The lack of a linkage mechanism between the two systems fails to meet the demands of modern buildings for efficient and coordinated fire protection systems. Third, glass bulb sprinkler heads are disposable; once the glass bulb breaks, the entire sprinkler head must be replaced, significantly increasing maintenance costs and workload.

[0004] Therefore, there is an urgent need for a new type of fire sprinkler system to solve the problems existing in the current technology. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Each of the aforementioned fire sprinkler zones is equipped with one of the aforementioned multi-source fire monitoring modules and one of the aforementioned electrically controlled sprinkler modules. The fire alarm module, the N zone control modules, and the N multi-source fire monitoring modules are respectively connected to the central control module. The N zone control modules are connected one-to-one with the N electrically controlled sprinkler modules.

[0010] in,

[0011] The multi-source fire monitoring module is used to monitor multi-source fire data in the fire sprinkler zone in real time and transmit the monitored multi-source fire data to the central control module.

[0013] The partition control module is used to receive a first control command sent by the central control module, and control the opening and closing of the electrically controlled sprinkler module connected to the partition control module according to the first control command;

[0014] The electronically controlled sprinkler module is used to spray and extinguish fires in the fire sprinkler zone under the control of the corresponding zone control module.

[0015] The fire alarm module is used to receive a second control command sent by the central control module, and to turn the alarm on or off according to the second control command.

[0016] Preferably, the electrically controlled sprinkler module includes at least one sprinkler head and at least one electric valve. Each sprinkler head is provided with a corresponding electric valve, which is used to control the connection and disconnection between the water supply pipeline of the corresponding sprinkler head and the sprinkler head.

[0017] Preferably, the multi-source fire monitoring module includes at least one temperature sensor and at least one smoke sensor, wherein the temperature sensor and smoke sensor of each multi-source fire monitoring module are evenly distributed within the fire sprinkler zone corresponding to the multi-source fire monitoring module, wherein,

[0018] The temperature sensor is used to monitor the temperature data of the area in real time and transmit the monitored temperature data to the central control module.

[0019] The smoke sensor is used to monitor the smoke concentration data of the area in real time and transmit the monitored smoke concentration data to the central control module.

[0020] Preferably, the multi-source fire monitoring module further includes at least one smart camera, and the smart cameras of each multi-source fire monitoring module are evenly distributed within the fire sprinkler zone corresponding to the multi-source fire monitoring module, wherein,

[0021] The smart camera is used to collect environmental images of the area in real time and transmit the collected environmental images to the central control module.

[0022] Preferably, the multi-source fire monitoring module further includes a first wireless communication module, and the temperature sensor, smoke sensor and smart camera are respectively connected to the central control module through the first wireless communication module.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. The multi-source fire monitoring module uses multiple devices such as temperature sensors, smoke sensors and smart cameras to monitor fire data from multiple dimensions. Compared with the traditional sprinkler system that only relies on temperature sensing, it greatly improves the accuracy and reliability of fire detection and effectively reduces the occurrence of false alarms.

[0030] 2. The central control module organically combines the multi-source fire monitoring module, the zone control module, and the fire alarm module, realizing the linkage between the sprinkler system and the fire alarm system.

[0031] 3. The electrically controlled spray module uses electric valves to control the spray heads, avoiding the drawbacks of traditional glass bulb spray heads which are disposable. When a fault occurs or maintenance is required, there is no need to replace the entire spray head; only the electric valves and other components need to be inspected or replaced, which significantly reduces the system's maintenance costs.

[0039] like Figure 1 As shown, this utility model embodiment provides an intelligent zone-controlled smart fire sprinkler system applied to a target fire zone, which is divided into N fire sprinkler zones, where N is a positive integer and N≥2. The system includes a central control module 1, a fire alarm module 2, N zone control modules 3, N multi-source fire monitoring modules 4, and N electrically controlled sprinkler modules 5. Each fire sprinkler zone is equipped with one multi-source fire monitoring module 4 and one electrically controlled sprinkler module 5. The fire alarm module 2, the N zone control modules 3, and the N multi-source fire monitoring modules 4 are respectively connected to the central control module 1, and the N zone control modules 3 are connected one-to-one with the N electrically controlled sprinkler modules 5.

[0040] Specifically, the multi-source fire monitoring module 4 is used to monitor multi-source fire data in the fire sprinkler zone in real time and transmit the monitored multi-source fire data to the central control module 1; the central control module 1 is used to receive the multi-source fire data transmitted by the multi-source fire monitoring module 4, and output a first control command to the corresponding zone control module 3 according to the multi-source fire data, and output a second control command to the fire alarm module 2 according to the multi-source fire data; the zone control module 3 is used to receive the first control command sent by the central control module 1, and control the opening and closing of the electrically controlled sprinkler module 5 connected to the zone control module 3 according to the first control command; the electrically controlled sprinkler module 5 is used to implement sprinkler fire extinguishing in the fire sprinkler zone under the control of the corresponding zone control module 3; the fire alarm module 2 is used to receive the second control command sent by the central control module 1, and turn the alarm on or off according to the second control command.

[0041] The working principle of the intelligent zone-controlled smart fire sprinkler system in this embodiment is as follows:

[0042] After the system starts, each multi-source fire monitoring module 4 monitors the multi-source fire data in its respective fire sprinkler zone in real time and transmits the monitored multi-source fire data to the central control module 1. The central control module 1 receives the multi-source fire data transmitted by the multi-source fire monitoring module 4 and outputs a first control command to the corresponding zone control module 3 and a second control command to the fire alarm module 2 based on the multi-source fire data. The zone control module 3 receives the first control command sent by the central control module 1 and controls the opening and closing of the electrically controlled sprinkler module 5 connected to the zone control module 3 according to the first control command. Under the control of the corresponding zone control module 3, the electrically controlled sprinkler module 5 sprays fire extinguishing in the fire sprinkler zone it is located in. At the same time, the fire alarm module 2 receives the second control command sent by the central control module 1 and turns the alarm on or off according to the second control command.

[0043] Specifically, in this embodiment, the central control module 1 is the core control unit of the entire system. It has a built-in preset fire judgment algorithm. The central control module 1 receives multi-source fire data transmitted by the multi-source fire monitoring module 4, analyzes and processes the multi-source fire data through the fire judgment algorithm, and determines whether a fire has occurred. If a fire is determined to have occurred, it outputs a corresponding first control command to the corresponding zone control module 3, so that the corresponding zone control module 3 controls the electric sprinkler module 5 to start and extinguish the fire. At the same time, it outputs a corresponding second control command to control the fire alarm module 2 to start the alarm, so as to realize the fire alarm reminder and facilitate the timely evacuation of personnel in the target area.

[0044] Specifically, the central control module 1 in this embodiment can adopt an industrial-grade PLC controller (such as Siemens S7-1200 / 1500 series, Mitsubishi FX5U series, Schneider M258 series), an embedded industrial computer (such as Advantech UNO-2172G series, Huabei Industrial Control BIS-6600 series), or a dedicated fire controller (such as Beida Jade Bird JBF-11S series, Haiwan GST-QKP01 series); the zone control module 3 can adopt an intelligent relay module (such as Siemens 3RK1 series, Omron G5LE series) or a microcontroller (MCU) development board (such as STM32F4 series, Arduino MKR series).

[0045] Specifically, for ease of control and equipment layout, each zone control module can be set up in the corresponding fire sprinkler zone.

[0046] It should be noted that the data analysis and processing method of determining whether a fire has occurred based on multi-source fire data such as temperature, smoke, and on-site images by using a preset fire judgment algorithm is a mature existing technology. The improvement in this embodiment lies in the improvement of the overall hardware system architecture of the fire sprinkler system. Through the central control module 1, fire alarm module 2, N zone control modules 3, N multi-source fire monitoring modules 4, and N electrically controlled sprinkler modules 5, a smart fire sprinkler system that can realize the linkage between sprinkler and alarm is built. It does not involve the improvement of specific data processing methods such as fire judgment, that is, it does not involve the improvement of computer programs.

[0047] In one embodiment, the electrically controlled sprinkler module 5 includes at least one sprinkler head 51 and at least one electric valve 52. Each sprinkler head 51 is correspondingly provided with an electric valve 52, which is used to control the connection and disconnection between the water supply pipe and the sprinkler head 51. It should be noted that in this embodiment, the sprinkler head 51 is a common sprinkler head without control components such as glass bulbs, and the opening and closing of the sprinkler head 51 is controlled solely by the energization and de-energization of the electric valve 52.

[0048] In this embodiment, the precise control of the electric valve 52 enables independent operation of each sprinkler head 51, improving the targeting and efficiency of fire extinguishing.

[0049] In one embodiment, the multi-source fire monitoring module 4 includes at least one temperature sensor 41 and at least one smoke sensor 42. The temperature sensor 41 and smoke sensor 42 of each multi-source fire monitoring module 4 are evenly distributed in the fire sprinkler zone corresponding to the multi-source fire monitoring module 4. The temperature sensor 41 is used to monitor the temperature data of the area in real time and transmit the monitored temperature data to the central control module 1; the smoke sensor 42 is used to monitor the smoke concentration data of the area in real time and transmit the monitored smoke concentration data to the central control module 1.

[0050] In this embodiment, by monitoring fire data from multiple dimensions such as temperature and smoke concentration, it is possible to more accurately determine whether a fire has occurred, effectively reducing the false alarm rate.

[0051] Based on the previous embodiment, in one embodiment, the multi-source fire monitoring module 4 further includes at least one smart camera 43. The smart cameras 43 of each multi-source fire monitoring module 4 are evenly distributed in the fire sprinkler zone corresponding to the multi-source fire monitoring module 4. The smart cameras 43 are used to collect environmental images of the area in real time and transmit the collected environmental images to the central control module 1.

[0052] In this embodiment, the addition of the smart camera 43 further enriches the data sources for fire monitoring, and image recognition technology can be used to assist in judging the fire situation.

[0053] In one embodiment, the multi-source fire monitoring module 4 further includes a first wireless communication module 44. The temperature sensor 41, the smoke sensor 42, and the smart camera 43 are respectively connected to the central control module 1 through the first wireless communication module 44. The first wireless communication module 44 is a Zigbee module or a Wi-Fi module.

[0054] In this embodiment, the multi-source fire monitoring module 4 and the central control module 1 communicate wirelessly, which facilitates the installation and layout of the equipment and improves the flexibility and scalability of the system.

[0055] In one embodiment, temperature sensor 41 is a DS18B20 digital temperature sensor, smoke sensor 42 is an MQ-2 smoke concentration sensor, and smart camera 43 is a BOVA multispectral flame detection camera. These mature sensor and camera products ensure the accuracy and reliability of the monitoring data.

[0056] In one embodiment, the fire alarm module 2 includes multiple audible and visual alarms 21, which are evenly distributed within the target fire protection area to ensure that all personnel within the target fire protection area can receive the alarm signal in a timely manner when a fire occurs.

[0057] In one embodiment, the central control module 1 communicates with N partition control modules 3 through a LoRa wireless communication network. The LoRa wireless communication network has advantages such as long distance and low power consumption, which can meet the stable data transmission requirements between the modules of the system.

[0058] In one embodiment, the intelligent zone-controlled smart fire sprinkler system further includes a second wireless communication module 6, which is connected to the central control module 1 to facilitate data interaction between the system and external devices, enabling remote monitoring and management functions. Specifically, the second communication module can be a 4G / 5G module.

[0059] The workflow of this system will be further explained in detail below with a specific example:

[0060] Assuming the target fire zone is an office building, it is divided into N=5 fire sprinkler zones, namely zone 1, zone 2, zone 3, zone 4 and zone 5.

[0061] Within each fire sprinkler zone, a multi-source fire monitoring module 4 and an electrically controlled sprinkler module 5 are evenly installed. Taking zone 1 as an example, the multi-source fire monitoring module 4 includes three DS18B20 digital temperature sensors 41, three MQ-2 smoke concentration sensors, and two BOVA multispectral flame detection cameras. They are connected to the central control module 1 via a Zigbee module to monitor the temperature, smoke concentration, and environmental image data within zone 1 in real time, and transmit the data to the central control module 1.

[0062] The electrically controlled sprinkler module 5 includes five sprinkler heads 51, each sprinkler head 51 corresponding to an electric valve 52. The electric valve 52 is connected to the zone control module 3 of zone 1, and the zone control module 3 is connected to the central control module 1 via a LoRa wireless communication network. When the central control module 1 receives fire data transmitted from the multi-source fire monitoring module 4 of zone 1 and determines that a fire has occurred, it outputs a first control command to the zone control module 3 of zone 1. The zone control module 3 controls the corresponding electric valve 52 to open according to the first control command, so that the sprinkler head 51 sprays water to extinguish the fire in zone 1. At the same time, the central control module 1 outputs a second control command to the fire alarm module 2, and the audible and visual alarm 21 in the fire alarm module 2 is activated, emitting an alarm signal throughout the office building.

[0063] The second wireless communication module 6 is connected to the central control module 1. Property management personnel can communicate with the second wireless communication module 6 via a mobile APP or computer to remotely monitor the system's operating status, view the fire monitoring data of each fire sprinkler zone and the working status of the sprinkler system, and achieve intelligent management.
