For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Common fire alarm monitoring technologies mainly include: smoke detectors, ionization smoke detectors, contact temperature measurement, and aiming type infrared spot temperature measuring instruments. These types of detectors have problems such as response delay, false alarms, and inability to be flexibly configured based on the specific network conditions of the fire alarm system.

[0046] In the prior art, thermal imaging fire detection systems have gradually received attention because they are not limited by light and can directly detect the heat radiation generated by fires. However, the existing thermal imaging fire detection systems have high energy consumption.

[0047] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] For this reason, in this embodiment, a fire alarm monitor is provided, as Figure 1 shown, a fire alarm monitor, the fire alarm monitor includes: a plurality of threshold temperature control modules 10, a control module 20, and a thermal imaging module 30;

[0049] A plurality of threshold temperature control modules 10 are respectively arranged in a plurality of preset monitoring areas, and are used for outputting a monitoring signal when the area temperature of the preset monitoring area is detected to be greater than a preset temperature threshold;

[0050] The control module 20 is respectively communicatively connected with the plurality of threshold temperature control modules 10, and is used for outputting a control signal after receiving the monitoring signal, and controlling the thermal imaging module 30 to point to the target monitoring area corresponding to the monitoring signal;

[0051] The thermal imaging module 30 is connected to the control module 20, and is used for starting after receiving the control signal, and outputting the thermal imaging image of the target monitoring area after collecting it;

[0052] The control module 20 is further used for determining a fault point and a fault cause based on the thermal imaging image and the target area temperature in the monitoring signal, and outputting the fault point and the fault cause.

[0053] Specifically, the area to be monitored is divided into multiple preset monitoring areas, and a threshold temperature control module 10 is provided on each preset monitoring area. The threshold temperature control module 10 collects the temperature changes of its respective preset monitoring areas in real time, and outputs a monitoring signal to the control module 20 when the detected area temperature is greater than the preset temperature threshold. Optionally, the threshold temperature control module 10 can be a sensor for the relationship between the monitored area temperature and the threshold temperature. In addition, the threshold temperature control module 10 can also send the real-time temperature to the control module 20.

[0054] Specifically, after receiving the monitoring signal, the control module 20 outputs a control signal to the thermal imaging module. The control signal can specifically be a start signal, and the control signal is to control the thermal imaging module 30 to point to the target monitoring area and to control the thermal imaging module 30 to start.

[0055] Specifically, the thermal imaging module 30 is fixedly connected to the control module 20, and the thermal imaging module 30 points to the target monitoring area corresponding to the control signal based on the control of the control module. The thermal imaging module 30 is communicatively connected to the control module 20, and the thermal imaging module 30 outputs the thermal imaging image of the acquired target monitoring area to the control module 20. It should be noted that the thermal imaging module 30 does not need to collect thermal imaging images in real time. When no control signal is received, it is in a sleep state, and only when a control signal is received, it starts and collects the thermal imaging image of the target monitoring area. Alternatively, in this embodiment, the thermal imaging module 30 can also collect the overall data of the area to be monitored before starting, start after receiving the control signal, and process the local data of the target monitoring area in the overall data to obtain a thermal imaging image, thereby reducing energy consumption.

[0056] Specifically, after receiving the thermal imaging image and the area temperature, the control module 20 further analyzes the area temperature and the thermal imaging image to obtain the fault point and the cause of the fault. The control module 20 specifically converts the thermal imaging image and the area temperature into digital signals and analyzes them. The control module 20 specifically uses AI to assist in judging the fault point and the cause of the fault.

[0057] In addition, after detecting the fault point and the cause of the fault, the control module 20 extinguishes the fire or cools down the fault point through the fire-fighting device. The control module 20 can accurately judge the fault point, and the thermal imaging module 30 can accurately present the degree of the alarm situation, realizing active fire protection.

[0058] It should be noted that among the multiple preset monitoring areas, if the temperatures of multiple target monitoring areas are all greater than the preset temperature threshold, the control module 20 controls the thermal imaging module 30 to collect thermal imaging images in a preset order, where the preset order can be the temperature level or the order set for the preset monitoring areas in advance.

[0059] Exemplarily, if there are four devices in the equipment room, a threshold temperature control module 10 is set for each device. The threshold temperature control module 10 non-contactedly collects the device temperature of the device, and when it monitors that the temperature of the target device is greater than the preset temperature threshold, it outputs a monitoring signal. The control module 20 controls the thermal imaging module 30 to point to the target device, and collects the thermal imaging image of the target device through the thermal imaging module 30. The control module 20 further makes a judgment based on the thermal imaging image and the device temperature using an AI (Artificial Intelligence) algorithm to accurately find the faulty electricity and the cause of the fault.

[0060] The fire alarm monitor provided by the present invention monitors multiple preset monitoring areas in real time through multiple threshold temperature control modules 10, collects their respective preset monitoring areas, and when it detects a target monitoring area where the area temperature is greater than the preset temperature threshold, it outputs a monitoring signal. The control module 20 outputs a control signal to the thermal imaging module 30 and controls the thermal imaging module 30 to point to the target monitoring area. After the thermal imaging module 30 is started, it outputs the collected thermal imaging image to the control module 20, and the control module 20 then judges the fault point and the cause of the fault based on the thermal imaging image and the area temperature. Compared with the traditional thermal imaging detection system, the thermal imaging module of the present application does not need to be turned on for a long time, greatly reducing the energy consumption. In addition, the present application combines non-contact temperature measurement technology with the processing and analysis of the control module to further enhance, analyze, and extract features from the thermal imaging module, realizing more accurate target recognition and analysis, effectively reducing the false alarm rate. At the same time, the fault point and the specific cause can be quickly found, further improving the accuracy and efficiency of fire warning.

[0061] In some alternative embodiments, as Figure 2 shown, the control module 20 includes: a combination module 21, a base 22, and a rotator 23;

[0062] The rotator 23 is fixedly connected to the base 22, the thermal imaging module 30 is arranged on the rotator 23, and the combination module 21 is arranged in the base 22, wherein the combination module 21 is used for sending control signals and communication.

[0063] Specifically, the combination module 21, as a control and communication module, when receiving the monitoring signal, controls the rotator 23 to point to the target monitoring area, so that the thermal imaging module 30 points to the target monitoring area. It should be noted that a corresponding relationship is set between the preset monitoring area and the azimuth information of the rotator 23, that is, after the combination module 21 receives the monitoring signal, it outputs the azimuth information corresponding to the target monitoring area to the rotator 23, so as to control the rotator 23 to point to the target monitoring area.

[0064] Exemplarily, the rotator 23 can specifically be a pan-tilt head.

[0065] In some alternative embodiments, such as Figure 3 shown, the combined module 21 includes:

[0066] A communication unit a, which is respectively communicatively connected to the threshold temperature control module 10 and the thermal imaging module 30;

[0067] A control unit b, which is used to send control signals to the thermal imaging module 30;

[0068] An electromagnetic protection unit c, which is used for electromagnetic protection;

[0069] A gateway unit d, which is used for network communication;

[0070] A power supply unit e, which is used to provide power supply;

[0071] A storage unit f, which is used for the information during the process of the control unit b processing signals.

[0072] Specifically, the control unit b can be an MCU (Microcontroller Unit). The gateway unit d is used to connect the control unit b to external network devices. Thus, the control unit b sends the data during the processing process to the external network devices. The electromagnetic protection unit c is used for electromagnetic protection of the combined module 21. The power supply unit e is used to supply power to the combined module 21 and the thermal imaging module 30, and the storage unit f is used to store the output during the processing process of the control unit b.

[0073] The combined module 21 is set as an integrated structure, with the outer shell made of high-strength aluminum alloy and the internal layout optimized to reduce electromagnetic interference.

[0074] Exemplarily, the communication interface of the micro gateway supports PoE power supply and supports RS-485, RS-232 wired communication and Wi-Fi wireless communication to achieve efficient data transmission; the power supply of the micro gateway adopts a low-power design and supports DC 12V / 24V input and PoE power supply.

[0075] In some alternative embodiments, the threshold temperature control module 10 is a passive infrared temperature sensor.

[0076] Specifically, both the passive infrared temperature sensor and the optical lens in the thermal imaging module 30 use long-wave infrared, that is, the wavelength ranges from 8 μm to 14 μm. The control unit b converts the heat radiation wave electrical signal collected by the passive infrared temperature sensor into a high-definition thermal image. The control unit b further conducts in-depth analysis on the thermal image and the thermal imaging module 30 by combining the flame AI (Artificial Intelligence) algorithm and non-contact temperature measurement technology to quickly identify temperature characteristics and temperature anomalies, effectively reducing the false alarm rate. In addition, the control unit b can also combine the fire alarm feature recognition algorithm to determine whether there is a fire risk, and immediately trigger the alarm mechanism when detecting abnormal high temperature or fire alarm features.

[0077] In some alternative embodiments, the thermal imaging module 30 includes:

[0078] A thermal imaging unit for collecting and outputting a thermal imaging image of the target monitoring area.

[0079] Specifically, the thermal imaging unit can be a thermal imaging camera, and the thermal imaging unit converts the heat radiation wave electrical signal of the target monitoring area collected into a high-definition thermal image.

[0080] In some alternative embodiments, the thermal imaging module 30 further includes:

[0081] A built-in infrared temperature sensing module for collecting and outputting the temperature of the target monitoring area.

[0082] Specifically, the built-in infrared temperature sensing module can further improve the accuracy of the thermal imaging unit's collection.

[0083] In some alternative embodiments, the control unit b determines the digital scene of the preset monitoring area, generates a two-dimensional array, and determines the state of each cell in the two-dimensional array based on the thermal imaging image and the area temperature, and determines the fault point based on the state of each cell;

[0084] The control unit b generates a digital scene based on the temperature quantification of the passive infrared temperature sensor, the quantitative and qualitative thermal imaging composition, and the vertex composition of the two-dimensional array, that is, quantification, fixed-point, and qualitative, thereby calibrating the monitoring orientation and accurately finding the fault location. Among them, the normal state is set to 30 degrees Celsius higher than the room temperature state.

[0085] Specifically, the control unit b pre-constructs a digital scene for the monitoring area, generates a two-dimensional array, divides the two-dimensional array into cells, each cell representing a square on the preset monitoring area map, and each square has three states, namely room temperature state 0, normal state 1, and warning state 2. Determine the state of each square according to the collected thermal imaging image and the temperature of the area, obtain a state distribution map, and further analyze the preset monitoring area based on the state distribution map to obtain the fault point. In addition, the control unit b uses the flame AI algorithm for rapid and accurate identification of flame characteristics and temperature anomalies.

[0086] Exemplarily, if the monitoring area is an equipment room, analyze the equipment based on the state distribution map to accurately monitor the fault point of the equipment.

[0087] The control unit b determines the temperature of the fault point based on the thermal imaging image and the temperature of the target area, and obtains the cause of the fault after analyzing based on the temperature and the fault point.

[0088] Specifically, analyze the cause of the fault by combining the temperature of the fault point and the target monitoring area. It can also detect whether a fire may occur for pre-judgment.

[0089] In some optional embodiments, as Figure 1 shown, the fire alarm monitor further includes:

[0090] An alarm module 40, the alarm module 40 is connected to the control module 20, receives the alarm signal sent by the control module 20 and performs an alarm operation. The temperature threshold of the preset alarm range is set within an adjustable range of 20 degrees Celsius to 100 degrees Celsius. The alarm temperature range is set between 50 and 70 degrees Celsius. Specifically, the alarm temperature can be automatically adjusted according to the ambient temperature change.

[0091] Specifically, the alarm module 40 can be an alarm light or a buzzer, and the alarm module 40 can also be connected to the user's terminal device, so that when receiving the alarm signal, it is sent to the user's terminal device.

[0092] In some optional embodiments, as Figure 1 shown, the fire alarm monitor further includes:

[0093] A remote monitoring module 50, the remote monitoring module 50 is communicatively connected to the control module 20 for the user to view the preset monitoring area in real time based on the remote monitoring module 50.

[0094] Specifically, the fire alarm monitor has a remote video review function, and the user can remotely view the on-site situation in real time after receiving the alarm signal to confirm the alarm situation.

[0095] This application can improve the imaging quality and temperature measurement accuracy. By adopting a multi-band infrared detector and combining advanced image processing algorithms, the clarity of thermal images and the accuracy of temperature measurement are significantly enhanced. It can also enhance the accuracy of fire recognition. By combining the flame AI algorithm and non-contact temperature measurement technology, it can quickly and accurately identify flame characteristics and temperature anomalies, effectively reducing the false alarm rate. It can also improve the response speed. By being able to respond to temperature anomalies or flame characteristics in an extremely short time, it can win valuable time for personnel evacuation and fire fighting.

[0096] The present invention also proposes a control method for a fire alarm monitor, as Figure 4 shown. The control method of the fire alarm monitor is applied to the fire alarm monitor as described above. The control method of the fire alarm monitor includes:

[0097] Step S10, detecting whether the temperature of each area is greater than a preset temperature threshold through multiple threshold temperature control modules;

[0098] Step S20, when it is detected that the temperature of each area is greater than the preset temperature threshold, controlling the thermal imaging module to point to the target monitoring area corresponding to the control signal, and outputting a control signal, so that after the thermal imaging module is started, it acquires the thermal imaging image of the target monitoring area;

[0099] Step S30, receiving the thermal imaging image, determining the fault point and fault cause based on the thermal imaging image and the temperature of the target area, and outputting the fault point and fault cause.

[0100] The fire alarm monitor provided by the present invention monitors multiple preset monitoring areas in real time through multiple threshold temperature control modules 10, acquires their respective preset monitoring areas, and when it detects a target monitoring area where the area temperature is greater than the preset temperature threshold, it outputs a monitoring signal. The control module 20 outputs a control signal to the thermal imaging module 30 and controls the thermal imaging module 30 to point to the target monitoring area. After the thermal imaging module 30 is started, it outputs the acquired thermal imaging image to the control module 20, and the control module 20 then determines the fault point and fault cause based on the thermal imaging image and the area temperature. Compared with the traditional thermal imaging detection system, the thermal imaging module of this application does not need to be turned on for a long time, greatly reducing the energy consumption. In addition, this application combines non-contact temperature measurement technology with the processing and analysis of the control module, further enhances, analyzes, and extracts features of the thermal imaging module, realizes more accurate target recognition and analysis, and effectively reduces the false alarm rate. At the same time, the fault point and the specific reason can be quickly found, further improving the accuracy and efficiency of fire warning.
