[0025] Electrical fires are a major cause of indoor fires, especially in winter. Heating equipment may continue to run after people leave, potentially causing overheating and fire while people are asleep. People may not notice the fire in its early stages, leading to significant property damage or personal injury.
[0026] Reference Figure 1 This utility model provides a display device, the display device comprising:
[0027] Object temperature detection module 10, prompting module 40 and control module 30;
[0028] The control module 30 is connected to the object temperature detection module 10 and the prompting module 40 respectively;
[0029] The object temperature detection module 10 is used to detect the temperature information of each target object within a set spatial range and output it to the control module 30.
[0030] The control module 30 is used to control the prompt module 40 to display prompt information and / or play prompt audio when a target object with a temperature value greater than a temperature threshold exists within a set spatial range.
[0031] It should be noted that the object temperature detection module 10 detects the temperature information of each target object within a set spatial range. The target objects are determined by the R&D personnel during the R&D process and stored in the memory of the display device via a program. This solution does not limit the specific type of the target object. The object temperature detection module 10 uses a non-contact testing method to detect the temperature information of the target object. The object temperature detection module 10 may include non-contact measuring instruments such as infrared thermometers, optical pyrometers, total radiation thermometers, and colorimetric thermometers. The object temperature detection module 10 detects the temperature information of each target object within a set spatial range, and the temperature information may include temperature values, temperature ranges, temperature change rates within a set time period, and temperature change trends, etc. It is easy to understand that the non-contact measuring instruments obtain the temperature information of the target object by detecting and processing its radiation information. The object temperature detection module 10 has a detection end with a certain detection angle and range for receiving the radiation information of the target object within the set spatial range. The set spatial range can be determined by the R&D personnel. Furthermore, the spatial range determined by the measurement angle of the detection end of the object temperature detection module 10 is the maximum range of the set spatial range. The measurement angle determines the spatial range in which light rays can be incident on the detection end. The object temperature detection module 10 can directly detect the temperature value within the set spatial range and plot a temperature map of the set spatial range.
[0032] After receiving the temperature information output by the object temperature detection module 10, the control module 30 can first obtain the highest temperature within a set spatial range, and then compare this highest temperature with a temperature threshold. If the highest temperature value is greater than the temperature threshold, it indicates that there may be a risk of overheating and catching fire of the target object within the set spatial range. It is easy to understand that objects of different materials have different ignition points, and the temperatures of the resulting flames also differ. The temperature threshold can be set or adjusted after determining the specific type of target object within the spatial range that the display device needs to detect. The temperature threshold can be specifically determined by the R&D personnel; or it can be adjusted subsequently by the customer.
[0033] The control module 30 is used to control the prompting module 40 to display prompt information and / or play prompt audio when a target object with a temperature value greater than a temperature threshold exists within a set spatial range. The prompting module 40 is used to alert the user of a risk within the preset spatial range; specifically, the prompting module 40 includes a display screen 310 and a speaker 320, which alert the user by displaying prompt information and / or playing prompt audio. Considering that the user may be asleep, and considering that the longer the object remains overheated, the greater the risk of fire, the control module 30 can control the prompting module 40 to increase the volume of the prompt audio playback if no processing instruction is received from the user within a first time period.
[0034] The control module 30 may include controllers such as MCU, FPAG, SOC or IC.
[0035] It should be noted that the display device can be used in homes to detect target objects and provide temperature alerts, thereby reminding users when the temperature of a detected target object in the home is abnormal.
[0036] This utility model discloses a display device, comprising: an object temperature detection module 10, a prompting module 40, and a control module 30; the control module 30 is connected to both the object temperature detection module 10 and the prompting module 40; the object temperature detection module 10 is used to detect the temperature information of each target object within a set spatial range and output it to the control module 30; the control module 30 is used to control the prompting module 40 to display prompt information and / or play prompt audio when a target object within the set spatial range has a temperature value greater than a temperature threshold, thereby prompting the user. This utility model obtains the temperature of target objects within a set space through the object temperature detection module 10 and alerts the user when the temperature exceeds a temperature threshold.
[0037] The temperature values of various target objects within a defined spatial range differ under natural or normal operating conditions. To perform temperature detection and over-temperature assessment for different types of target objects, the display device further includes:
[0038] The object contour sensor 20 is used to detect the shape contour information of each target object within a set spatial range, and output a voltage signal corresponding to the shape contour information to the control module 30.
[0039] The control module 30 is used to determine the type of the target object corresponding to the voltage signal when the voltage signal is received;
[0040] The control module 30 is also used to control the prompt module 40 to display prompt information and / or play prompt audio when there is a target object in the set space range whose temperature value in the temperature information is greater than the judgment temperature value corresponding to its target object type.
[0041] It's easy to understand that in industrial design, different types of products have unique shape characteristics to facilitate quick identification. For example, a kettle has a body and a spout, a sofa has a long backrest and a seat, and a stool has legs and a seat.
[0042] The object contour sensor 20 detects the shape contour information of each target object and outputs a voltage signal corresponding to the shape contour information to the control module 30. The object contour sensor 20 may include a laser contour sensor, an image sensor, or a microwave sensor. It should be noted that, due to the different types of sensors selected for the object contour sensor 20, the aspects of the voltage signal carrying the shape contour information may differ.
[0043] In one example, the object contour sensor 20 directly outputs the voltage signal corresponding to the outline information of the target object to the control module 30, which then processes the data to obtain the type of the target object.
[0044] If the object contour sensor 20 is a laser contour sensor, this sensor acquires the contour information of the target object by scanning the surface of the target object with a laser beam and measuring the reflection or scattering of the laser beam. Specifically, when the laser beam irradiates the surface of the target object, the beam will be scattered or reflected by the tiny uneven structures of the target object surface. These scattered or reflected light signals are then captured by a receiver and converted into electrical signals. The photosensitive element (such as a photodiode) in the receiver converts the light signals into electrical signals related to the light intensity; the stronger the received light intensity, the larger the corresponding voltage amplitude. The distance between the laser beam and the surface of the target object can be calculated from the amplitude and time information of the voltage signal, thereby obtaining the contour data of the target object and determining the type of the target object.
[0045] If the object contour sensor 20 is an image sensor (such as CMOS or CCD), it consists of multiple individual pixel sensors, each corresponding to one pixel. When these pixel sensors receive optical signals, they convert photons into electrons, thereby generating a corresponding voltage intensity. This voltage intensity is ultimately output as the pixel value of that pixel, used to represent light intensity. Therefore, the stronger the received optical intensity, the larger the generated voltage value. It is easy to understand that the pixel values corresponding to the same object are roughly the same. Based on the amplitude of the voltage signal, the contour information of the target object can be obtained, thereby determining the type of the target object.
[0046] If the object contour sensor 20 is a microwave sensor, the microwave sensor is based on radar technology and detects the target object by emitting microwaves and receiving their reflected signals. These microwave signals will scatter or reflect when they encounter the target object, and the reflected waves carry information about the target object's position, velocity, and shape. The control module 30 extracts the contour information of the target object by measuring parameters such as the frequency change, phase difference, or time delay of the signal.
[0047] Additionally, microwave sensors can scan space by changing the direction of the transmitting antenna or using multiple antenna arrays. This scanning method can generate a two-dimensional or three-dimensional image, showing the position and shape of the target object in space. In continuous wave mode, the sensor keeps the frequency and amplitude of the microwave signal constant, scanning the entire area by moving the antenna or adjusting the beam direction. This method is suitable for static or slowly moving targets. In pulse mode, the sensor sends short microwave pulses and repeats this process in different directions. By analyzing the pulse signals returned in each direction, the reflection intensity of the target object at different locations can be determined, thus constructing the outline of the target object.
[0048] In another example, the object contour sensor 20 and the control module 30 agree on a mapping relationship between the target object type and the corresponding voltage signal. For example, an output of 0.5V from the object contour sensor 20 represents a sofa as the target object type, and an output of 1V represents a kettle or similar target object type.
[0049] After determining the type of the target object based on the target object's shape contour information, the object contour sensor 20 outputs a corresponding voltage amplitude to the control module 30 according to the target object type; the control module 30 determines the type of the target object based on the received voltage amplitude.
[0050] The control module 30 is used to determine whether each target object within a set space is overheated by combining the target object's temperature and type. If a target object within the set space has a temperature value greater than the judgment temperature value corresponding to its type, the control prompt module 40 prompts the user. Specifically, the control module 30 determines whether the target object is overheated by comparing the detected target object temperature with the judgment temperature value corresponding to the target object's type. It is easy to understand that different objects have different ignition points and temperatures under normal operating conditions; the judgment temperature value can be set by the R&D personnel to determine whether different types of target objects are overheated. In this process, the control module 30 correlates the target object's outline information or type with the target object's judgment temperature value.
[0051] The control module 30 can analyze and process various types of data, and identify the external features of the target object based on the status of the detection data. Based on the distance, geometric size, and detailed features of the target object, it can distinguish and name / number the target object and its environment. (Refer to...) Figure 5 The temperature information of each target object within a set spatial range output by the object temperature detection module 10 can be drawn into an environmental target object temperature image. The control module 30 overlays and compares this temperature distribution image with the image formed by microwave scanning, thereby superimposing temperature data distribution on the target objects in the image, and naming and binding the target objects in the image according to the order of temperature from high to low.
[0052] The target object identification, naming, and temperature data will be stored as external features and statistically analyzed over a long period. After the target object moves, the location identification and detection data will be re-recorded and analyzed based on default or set time points. The control module 30 uses the highest temperature of all target objects in the environment as the criterion for outputting alert information.
[0053] The control module 30 detects whether there are target objects within the set space whose temperature values exceed the judgment temperature value corresponding to their target object type. Specifically, the control module 30 can name and number the identified target objects using software, and can perform data matching and long-term data sampling and storage between the target object temperature and the named target object. It can perform statistical analysis on the temperature data of each identifiable target object, and can statistically analyze the temperature change curve of the target object over a certain period of time. Based on this normal change curve, it can determine the normal temperature change range of the target object. It can issue a warning judgment for sudden data that significantly exceeds the change range, and after confirming that the range has been exceeded, it can issue image and sound warning actions. This helps users to deal with unexpected environmental situations in a timely manner.
[0054] In addition, by combining the environmental target object classification data collected by microwave scanning, a big data classification model can be established for the target objects in the environment. Based on the identification of the target object categories in the environment, the model formed by the accumulated long-term temperature data of the target objects can realize the binding of target object identification and temperature data.
[0055] Reference Figure 6 The temperature value corresponding to the target object type can be obtained by acquiring the temperature value of the target object during normal operation. Specifically, the control module 30 can automatically record the temperature data of the classified target objects within a preset space range every day, and make temperature records of target objects with higher temperatures for different time periods to form a database. It can compare and judge the new data and historical data to make dynamic judgments on the temperature of high-temperature target objects. Figure 6In this context, the temperature threshold is the aforementioned temperature value used for determination.
[0056] After the display device is powered on, the object contour sensor 20 and the object temperature detection module 10 perform data acquisition and output. The control module 30 collects data to identify environmental target objects and perform secondary matching of temperature data. It also identifies the data of target objects with higher temperatures at the time of power-on. After multiple transient data acquisitions, the stable average data is used as the temperature value of the target object and the judgment temperature value to determine whether to output an image / text and a special sound alert for abnormal temperature.
[0057] Even after the user turns off the display screen 310 of the display device using a button or remote control, the object temperature recognition module and control module 30 of this system continue to work, continuously detecting the temperature of the target object in the environment, recognizing abnormal temperatures of the target object and managing abnormal temperature reminder information. When the screen is not displayed, voice reminders can also be given.
[0058] It is easy to understand that the control module 30 controls the prompt module 40 to display different prompt information and / or play different prompt audio depending on the type of the target object being overheated, so that the user can quickly and directly understand the development of the situation.
[0059] This invention can identify the type of target object and the temperature of the target object by infrared recognition. It combines data accumulation and comprehensive judgment with manually set prompt thresholds to realize the function of classifying and identifying the temperature of target objects in indoor environments and providing abnormal alerts.
[0060] It should be noted that the object temperature detection module 10 and the object contour sensor 20 can be installed separately, allowing for adjustment of the desired detection range by changing their installation positions. Specifically, considering that the display device can be used in indoor environments, where the number of electrical appliances in the user's area is generally high, making it a key area for monitoring, placing the detection ends of the object contour sensor 20 and the object temperature detection module 10 on the side of the display device facing the user allows for focused detection of any overheated objects in that area. Furthermore, if the display device is used in a home, it is typically installed near the living room wall, directly facing the user's viewing area.
[0061] The object contour sensor 20 includes a microwave scanning and recognition circuit; the microwave scanning and recognition circuit is connected to the control module 30 and is used to send microwave signals to a set spatial range and output the received microwave reflected voltage signals to the control module 30.
[0062] It's easy to understand that microwave scanning and recognition circuits offer advantages such as high resolution, 3D data acquisition, rapid response, and strong environmental adaptability. Microwave detection technology boasts high spatial resolution, enabling precise measurement of the shape and size of target objects. This means that microwave sensors can capture subtle changes in the object's outline, providing a solid foundation for accurate subsequent identification of the object's type. Microwave sensors form point clouds by emitting high-frequency electromagnetic waves and receiving reflected signals. These point clouds can roughly indicate the object's outline and the surrounding infrastructure. Compared to images, point clouds possess depth information, directly providing 3D spatial data, making the object's outline more three-dimensional and realistic. Due to the use of high-frequency electromagnetic waves for detection, microwave sensors have a fast response speed. They can complete the detection task of the target object in a short time, thereby improving the efficiency and real-time performance of acquiring the object's outline. Microwave sensors exhibit high reliability in various environments, unaffected by weather conditions such as light, rain, or snow. Furthermore, they are protected from factors such as poor sensor contact or external interference, ensuring the accuracy and stability of the object's outline data.
[0063] The object temperature detection module 10 includes an infrared detection circuit. This infrared detection circuit is connected to the control module 30 and is used to detect the infrared radiation emitted by each target object within a set spatial range, obtaining the temperature information of each target object. The infrared detection circuit features fast imaging speed, strong real-time performance, and high measurement accuracy. The infrared detection circuit has a very fast imaging speed, enabling it to quickly scan the target object and generate a temperature image. This allows the infrared detection circuit to complete the temperature measurement of a large number of target objects in a short time, improving work efficiency. The infrared sensing circuit can monitor the temperature changes of the target object in real time, providing instant data feedback. This is particularly important for scenarios requiring real-time temperature monitoring (such as industrial automated production lines). The infrared sensor can monitor the temperature changes of the target object in real time, providing instant data feedback. Modern infrared detection circuits have very high temperature measurement accuracy, typically within 2°C. This high-precision measurement capability ensures the accuracy and reliability of the data. Furthermore, the infrared detection circuit can not only measure the temperature of a single point on the target object but also draw a thermal image of the temperature gradient of the entire target object. This intuitive image display helps users to understand the temperature distribution of the target object more clearly.
[0064] Reference Figure 2 The prompting module 40 includes: a display screen 310 and a speaker 320;
[0065] The control module 30 is connected to the display screen 310 and the speaker 320 respectively;
[0066] The detection terminals of the microwave scanning recognition circuit and the infrared detection circuit are located on the side of the display screen 310 facing the user.
[0067] It is easy to understand that the display screen 310 also serves the function of displaying images to users and playing television programs or streaming media in daily activities. That is, the display screen 310 is installed facing the user's viewing area. However, the display screen 310 has a side with a screen and a side without a screen. The detection end of the microwave scanning recognition circuit and the detection end of the infrared detection circuit are located on the side of the display screen 310 facing the user; that is, the side of the display device with a screen.
[0068] Reference Figure 3 In one embodiment of this utility model, the display device further includes:
[0069] Wireless signal receiving module 50; the wireless signal receiving module 50 is connected to the control module 30 and is used to receive control signals output by the wireless remote controller and output them to the control module 30.
[0070] The control module 30 is used to modify the temperature threshold according to the maximum temperature modification instruction in the control signal.
[0071] The control module 30 is also used to determine and modify the determination temperature value of the relevant target object type according to the object temperature in the control signal;
[0072] The control module 30 is also used to adjust the size of the spatial range detected by the object contour sensor 20 and the object temperature detection module 10 according to the detection spatial range setting instruction in the control signal.
[0073] It should be noted that different users have different objects within the indoor space, and the user's judgment on the allowable temperature value for the target object type is based on personal factors. Therefore, this utility model provides a way for the user to actively modify the temperature threshold, the determination temperature value for the target object type, and the detection space range, so that the display device in this solution can better suit the user's daily use.
[0074] It is easy to understand that users can output control signals through the wireless remote control and modify the temperature threshold, the judgment temperature value of the target object type, and the detection space range through the settings page provided by the software in the display device.
[0075] The wireless signal receiving module 50 may include a communication receiving unit such as a WiFi receiving unit, a Bluetooth receiving unit, or a Zigbee receiving unit.

[0080] The wireless transmission module 60 may include a WiFi receiver unit, a Bluetooth receiver unit, or a Zigbee receiver unit, etc.
[0081] It should be noted that the wireless transmission module 60 can change the way it transmits notification information to the user's mobile device according to the distance between the user's mobile device and the display device.
[0082] If the user's mobile device is close to the display device, the wireless transmission module 60 can connect to the user's mobile device and send a prompt message directly to the user's mobile device; the user's mobile device can process the prompt message through the APP and remind the user through the user's mobile device's speaker 320, vibration motor and / or screen.
[0083] If the user's mobile device is far from the display device, and the wireless transmission module 60 cannot directly connect to the user's mobile device within the effective connection distance, the wireless transmission module 60 can transmit the prompt information to the server, and then the server can send the prompt information to the user's mobile device.
[0084] The user's mobile device can be a computer, mobile phone, iPad, or smartwatch, etc.
[0085] This utility model also proposes a television set, which includes the aforementioned display device. The specific structure of the display device is as described in the above embodiments.

The lower center position provides a good detection environment for the object contour sensor 20 and the object temperature detection module 10, ensuring that the user's viewing area is within the detection range of the object contour sensor 20 and the object temperature detection module 10 as much as possible.
