[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0023] It's important to note that a DTU (Data Terminal Unit) is a device used to transmit data from a device to a central system via a wireless network. DTUs are typically used to transmit data collected by various detectors to a central system via a wireless network, enabling remote data monitoring and management. DTUs can communicate with the central system via either a wired or wireless network, enabling real-time data transmission.

[0024] like Figure 1 As shown, a fire protection IoT intelligent DTU data transmission system includes several fire detectors, several infrared imaging devices 9, an alarm host 4, a cloud platform 2, a terminal device 1, a DTU 3, a controller 10 and a fire extinguishing device;

[0025] The fire detector is electrically connected to the alarm host 4, the alarm host 4 is connected to the cloud platform 2 through the DTU 3, and the cloud platform 2 is connected to the terminal device 1 through a wired or wireless signal;

[0026] The cloud platform 2 is connected to the controller 10 via a wireless signal, the controller 10 is connected to the alarm host 4 via the DTU, and the alarm host 4 is electrically connected to the fire extinguishing device;

[0027] The infrared imaging device is electrically connected to the alarm host 4, and the infrared imaging device is connected to the cloud platform 2 through the DTU 3. Direct connection to the alarm host 4 can achieve rapid local response, while the cloud connection with the cloud platform 2 can provide remote monitoring and analysis. The combination of the two can identify and handle emergencies more quickly; they can also exist independently or be implemented simultaneously. Even if one part fails, the other part can still ensure data transmission and alarm functions to meet the needs of different scenarios.

[0028] Furthermore, the terminal device 1 includes a fixed terminal 101 and a mobile terminal 102. The fixed terminal 101 is a computer host, and the mobile terminal 102 is a mobile phone or tablet. This enables real-time communication between the command center and the on-site information. Both can receive and send instructions in real time through computers or mobile devices, allowing for rapid response to emergencies. In particular, mobile phones and tablets allow on-site personnel to report situations in real time while on the move, adapting to complex and changing rescue environments and effectively improving the flexibility of on-site command and dispatch.

[0029] Furthermore, the infrared imaging device 9 works in conjunction with various detectors such as temperature, humidity, and smoke to collect fire alarm signals and on-site images in real time, and can provide more comprehensive fire warning information. The infrared imaging device 9 is provided with an API interface, and the API interface is connected to the terminal device 1. The user can remotely access and modify the settings of the infrared imaging device 9 through the terminal device 1. The image captured by the infrared imaging device 9 and the currently set fire judgment threshold can be displayed in real time on the terminal device 1. At this time, the user can remotely adjust the threshold for the infrared imaging device 9 to judge the occurrence of a fire, as well as the preset value for directly triggering the fire extinguishing device, according to actual conditions, through the terminal device 1. When the updated infrared imaging device 9 judges that there may be a fire risk according to the new standard, in addition to directly triggering the fire extinguishing device, it can also immediately notify relevant personnel through text messages, phone push, etc. to ensure that the emergency situation is quickly responded to, which is especially important for managing multiple sites or remote monitoring scenarios.

[0030] Furthermore, the fire detector includes a temperature detector 5, a humidity detector 6, and a smoke detector 7, all of which are electrically connected to the alarm host 4. When the temperature, humidity, and smoke detected by the temperature detectors 5, humidity detectors 6, and smoke detectors 7 reach or exceed their preset values, or when the amplitude of the change in the detected parameters reaches or exceeds the alarm setting value, an alarm signal is sent to the alarm host 4.

[0031] Furthermore, the fire extinguishing system includes a fire control cabinet 11 and a fire pump 8, which are electrically connected to each other. The fire control cabinet 11 is integrated with multiple fire pumps 8. Once the cloud platform 2 receives a fire alarm confirmation signal, it can remotely control the fire control cabinet 11 to activate the fire pumps 8, implementing emergency water supply. The fire pump 8's activation signal is then fed back to the alarm host 4. Simultaneously, the controller 10 wirelessly transmits this signal back to the cloud platform 2, enabling real-time monitoring of fire hazards.

[0032] Furthermore, it also includes an audible and visual alarm unit, which is electrically connected to the alarm host 4. Preferably, the audible and visual alarm unit includes a plurality of buzzers and a plurality of indicator lights set at the fire scene, which alert the staff by emitting alarm sounds and alarm lights, thereby playing the role of first-time safety monitoring.

[0033] The working principle of this utility model:

[0034] According to fire protection needs, various detectors are deployed in key areas to provide comprehensive coverage and ensure that there are no blind spots. When the amplitude of parameter changes detected by several fire detectors, preferably including several temperature detectors 5, humidity detectors 6, and smoke detectors 7, reaches or exceeds the alarm setting value, an alarm signal is sent to the alarm host 4. The infrared imaging device 9 connected to the alarm host 4 can achieve a fast local response. The alarm host 4 transmits the alarm signal to the sound and light alarm unit, activates the buzzer or indicator light at the fire scene, and at the same time, the alarm host 4 transmits the alarm signal data to the cloud platform 2 through the DTU 3. The cloud platform 2 pushes the alarm information to the terminal device 1 in a timely manner, and quickly sends the alarm signal to the corresponding person or device. After the staff confirms that the alarm is true, they remotely start the fire pump 8 and transmit the confirmation information to the controller 10 through the cloud platform 2. The controller 10 then transmits the signal to the alarm host 4. The alarm host 4 controls the action of the fire control cabinet 11, and then controls the start of several fire pumps 8 to achieve rapid fire extinguishing, and feeds back the action signal of the fire pump 8 to the alarm host 4. At the same time, the controller 10 feeds back the signal to the cloud platform 2 through wireless communication, thereby realizing real-time monitoring of fire hazards, making timely and correct responses, and effectively improving fire prevention and control and emergency response capabilities.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] (1) By cooperating with a plurality of fire detectors and a plurality of infrared imaging devices 9, it is possible to effectively monitor the alarm situation in real time, and cooperate with the alarm host 4 to quickly transmit the alarm signal to the cloud platform 2. Among them, the infrared imaging device 9 directly connects to the alarm host 4 to achieve a fast local response, and directly connects to the cloud platform 2 to provide remote monitoring and analysis; and activates the fire sound and light alarm unit through the alarm host 4 to remind and notify on-site personnel;

[0037] (2) The cloud platform 2 cooperates with the terminal device 1 to quickly transmit the fire alarm information to the corresponding person or device;

[0038] (3) The controller 10 cooperates with the alarm host 4 to realize real-time control of the start and stop of the fire pump 8, and the signal is fed back to the cloud platform 2 through the controller 10.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
