Description

Technical Field

[0001] The present invention belongs to the field of temperature monitoring and also to the field of cable television, IPTV and smart TV network applications, and particularly relates to a room temperature measurement system and method based on a Bluetooth remote controller and a set-top box. Background Art

[0002] In recent years, the heating industry has evolved from simple centralized heating to more refined, intelligent services. Temperature and humidity collection, as a fundamental data source, has become increasingly important. Traditional manual door-to-door temperature measurement methods, due to their low efficiency and high subjectivity, are no longer able to meet the needs of large-scale heating users. This has prompted the industry to actively explore automated temperature and humidity collection technologies.

[0003] Wireless IoT technology is booming. 4G, 5G, and Wi-Fi are being partially incorporated into temperature and humidity sensor devices. Products like wall-mounted thermometers and hygrometers with built-in communication modules, 86-type switch panels, and wall-mounted thermometers and hygrometers with built-in communication modules have emerged, enabling real-time collection and remote transmission of indoor temperature and humidity data. However, existing solutions present challenges in hardware cost, network stability, device installation difficulty, and long-term maintenance, hindering the implementation of large-scale services.

[0004] Among them, wall-mounted thermometers and hygrometers with built-in communication modules, typically equipped with 4G or 5G communication modules, can collect indoor temperature and humidity data in real time and transmit the data back to a backend server via a wireless network. The main advantage of this solution is that it can be flexibly installed in a suitable indoor location to accurately measure room temperature. However, it requires the integration of components such as communication modules, temperature measuring devices, and display screens. Data transmission incurs traffic charges, and transmission can become unstable due to signal obstruction. Furthermore, the thermometer's installation position is not fixed, resulting in low temperature acquisition accuracy and increased maintenance difficulties.

[0005] In addition, 86-type switch panels or 86-type power panels with built-in communication modules, such as 86-type switch panels with integrated temperature and humidity sensors, utilize their built-in 4G, 5G, or WiFi communication capabilities to collect and transmit temperature and humidity information without occupying additional space. This has the advantage of being a direct replacement for the existing switch panel without having to consider power supply issues, and its overall impact on the user's soft furnishings is minimal. However, it also has disadvantages such as the high data traffic costs required for operation, the high hardware cost of the product itself, the limited switch footprint, inaccurate measurements, low transmission stability, and difficult installation.

[0006] Overall, the field of temperature and humidity collection in the urban heating industry is still in the stage of continuous development and improvement, and urgently needs more cost-effective, stable and adaptable innovative solutions to meet the growing service needs. Summary of the Invention

[0007] The present invention provides a room temperature measurement system and method based on a Bluetooth remote control and a set-top box or a smart TV. The system and method are used in conjunction with a smart TV or a smart TV set-top box in a heating household to realize room temperature collection and data return functions. At the same time, the temperature and humidity collection function does not affect other infrared operations, Bluetooth operations, and voice control functions of the remote control set-top box, thereby achieving the effects of reducing equipment hardware costs, improving installation convenience, high communication stability, and high temperature and humidity measurement accuracy.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a room temperature measurement system based on a Bluetooth remote control and a set-top box, comprising a user-side device, wherein the user-side device comprises: a Bluetooth temperature measurement remote control, a remote control Dongle, and a smart TV or smart set-top box with temperature and / or humidity collection and reporting functions.

[0009] Preferably, the room temperature measurement system further includes an intermediate transmission link device; the intermediate transmission link device is one or a combination of broadcasting and television network equipment, Internet access equipment, and communication operator-specific link equipment.

[0010] Preferably, the room temperature measurement system further includes a platform-side device; the platform-side device is a data acquisition platform with temperature and / or humidity acquisition functions.

[0011] Preferably, a temperature measurement chip is installed on the mainboard of the Bluetooth temperature measurement remote control.

[0012] Preferably, the temperature measuring chip is a temperature measuring semiconductor chip.

[0013] Preferably, a heat dissipation hole is opened on the remote control housing corresponding to the position where the temperature measuring chip is installed in the Bluetooth temperature measuring remote control.

[0014] The present invention also provides a measurement method of a room temperature measurement system based on a Bluetooth remote controller and a set-top box, the measurement method comprising the following steps: S1: The Bluetooth temperature measuring remote control detects temperature and / or humidity. If the detection is successful, the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel; S2: After receiving the data from the Bluetooth temperature measurement remote control, the remote control Dongle stores the data in the flash and array, waiting for the smart TV or smart set-top box with temperature and / or humidity collection and reporting functions to obtain it; S3: A smart TV or smart set-top box with temperature and / or humidity collection and reporting capabilities obtains temperature and / or humidity data through a remote control dongle and uploads it to the platform-side device through an intermediate transmission link device.

[0015] Preferably, in step S1, the process in which the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel is provided with an intermittent wake-up method based on BLE; The intermittent wake-up method based on BLE is as follows: after the Bluetooth temperature measurement remote control is connected, it will remain in a constant connection state until it is in standby for 2.5 hours or the remote control Dongle actively disconnects, and then it will enter sleep mode. At this time, the Bluetooth temperature measurement remote control can be awakened by pressing a button and a broadcast of the connection is sent back; when the Bluetooth temperature measurement remote control and the remote control Dongle are disconnected, the Bluetooth temperature measurement remote control will wake up regularly every 15 minutes, collect temperature and / or humidity data, and send the temperature and / or humidity data to the remote control Dongle by broadcasting. After the data is sent, the Bluetooth temperature measurement remote control will enter sleep mode again.

[0016] Preferably, in the process of the Bluetooth temperature measuring remote control reporting the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel in step S1, a method for adjusting the frequency of dynamic temperature and humidity data reporting is provided; The method for adjusting the reporting frequency of dynamic temperature and humidity data is as follows: in the factory default state, when the Bluetooth temperature measurement remote control is connected to the remote control Dongle, temperature and humidity will be collected every 15 minutes. After the collection is successful, it will be transmitted to the remote control Dongle for storage via notif; The Bluetooth temperature measurement remote control can adaptively adjust the data collection and reporting interval according to the environmental change rate or user activity status, balancing accuracy and power consumption. The specific implementation method is as follows: M1 temperature measurement: Carry out 4 measurements according to the initial 15-minute cycle. Each time the measurement time comes, perform the temperature measurement operation and add the measured temperature to the temperature history data list; M2 Temperature change judgment: Starting from the fifth measurement, the temperature value of this measurement is compared with the average of the previous four measurements, and the absolute value of the difference between the two is calculated. If the absolute value of the difference is greater than 5°C, it is considered that a sudden temperature change has occurred, and the measurement cycle is shortened to 7.5 minutes; M3 remote control usage frequency judgment: Check the number of times the Bluetooth temperature measurement remote control is used within 15 minutes. If the number of uses is greater than 10 times, it is determined that the Bluetooth temperature measurement remote control is in a high-frequency use scenario, that is, the physical location of the Bluetooth temperature measurement remote control is likely to have changed. The measurement cycle is also shortened to 7.5 minutes. M4 comprehensive judgment: If the Bluetooth temperature measurement remote control is used 0 times within 15 minutes and the number of data in the temperature history data list is greater than 1, calculate the average absolute value of the difference between adjacent temperature values ​​in the temperature history data. If the average value is less than 1°C, the threshold can be adjusted according to the actual situation. It is considered that the temperature change is not significant and the measurement period is extended to 30 minutes. M5 cycle adjustment post-processing: Regardless of whether the measurement cycle is extended or shortened, after the adjustment is completed, the number of remote control usages will be reset to 0. If the measurement cycle is extended, to avoid excessive historical data usage, the temperature history data list will retain the most recent 4 data items. M6 loop execution: Repeat steps 1-5 above according to the adjusted measurement cycle to adaptively adjust the data reporting interval based on the rate of environmental change and user activity status.

[0017] Preferably, the remote control Dongle in step S2 has a function of reserving a protocol interface to obtain multi-party data, and has a function of abnormal temperature measurement and judgment based on multi-terminal data; The specific judgment process of the abnormal temperature measurement judgment function based on multi-terminal data is as follows: P1: Remote controller Dongle is powered on and started; P2: Device connection judgment: The remote control Dongle determines whether a third-party device is connected. If a third-party device is connected, its data is obtained through the reserved protocol interface; if no third-party device is connected, the temperature data of the matching Bluetooth temperature measurement remote control is directly obtained; P3: Third-party data verification: After obtaining data from a third-party device, verify the data based on the Modbus protocol. If the verification succeeds, extract the temperature and humidity data of the third-party device; if the verification fails, record an error log and ignore the data. P4: Data integration: Whether it is temperature and humidity data obtained from third-party devices or directly obtained from the Bluetooth temperature measurement remote control, it will be integrated; P5: Abnormal Judgment: First, determine whether the temperature difference between the third-party device and the Bluetooth temperature measuring remote control exceeds 3°C. If it exceeds 3°C, further determine whether the temperature of the third-party device has changed by more than 5°C compared to 15 minutes ago. If so, it is defined as abnormal data, and reporting stops and abnormal information is recorded. If the temperature of the third-party device has not changed by more than 5°C compared to 15 minutes ago, then determine whether the temperature of the remote control has changed by more than 5°C compared to 15 minutes ago. If so, it is also defined as abnormal data, and reporting stops and abnormal information is recorded. If it does not exceed, the data is determined to be normal and reporting is carried out. If the temperature difference between the third-party device and the remote control does not exceed 3°C, the data is directly determined to be normal and reporting is carried out.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Significantly Reduced Equipment Costs: Compared to existing temperature and humidity acquisition equipment that relies on 4G, 5G, or WiFi communication modules, this invention adds a temperature measurement chip to the Bluetooth remote control motherboard and uses the smart TV network to transmit data. This eliminates the need for expensive communication modules, significantly reducing equipment procurement and operating costs and facilitating large-scale deployment. 2. Greatly improves installation convenience: Traditional equipment installation is complex. This invention only requires installing the temperature collection and reporting APK software on the smart TV or set-top box and using a modified Bluetooth remote control. Ordinary users can easily complete the installation, reducing installation difficulty and time cost. 3. Effectively ensure communication stability: Compared to existing 4G, 5G, and WiFi-based solutions that are subject to interference from factors such as signal and traffic, this invention utilizes the fixed network channel of smart TVs or set-top boxes to avoid signal fluctuations and traffic restrictions, ensuring stable transmission of temperature and humidity data. Furthermore, because there is no need to consider network bandwidth limitations, the frequency of data transmission can be increased compared to traditional solutions, achieving a reporting frequency of ≥4 times per hour, providing reliable data support for heating control. 4. Effectively ensure the accuracy of temperature and humidity measurement: Compared with some existing equipment that use low-performance sensors due to space or cost, the present invention uses temperature measuring semiconductor chips as acquisition sensors, optimizes algorithms and circuits, and designs a variety of temperature measurement, correction and feedback logic. It can accurately sense changes in temperature and humidity, provide high-precision data for heating companies, help accurately control heating parameters, and improve the quality of heating services.

[0026] The room temperature measurement system also includes intermediate transmission link equipment; the intermediate transmission link equipment is one or a combination of broadcasting and television network equipment, Internet access equipment, and communication operator-specific link equipment.

[0027] The room temperature measurement system also includes platform-side equipment; the platform-side equipment is a data acquisition platform with temperature and / or humidity acquisition functions.

[0028] The room temperature measurement system of this invention is designed for temperature measurement and data collection by heating companies. It works in conjunction with smart TVs or smart TV set-top boxes in heating households to collect room temperature data and transmit it back. Furthermore, the temperature and humidity collection function does not affect the remote control's other infrared and Bluetooth functions, or the voice control of the set-top box.

[0029] The present invention mainly includes three parts: user side, platform side and intermediate transmission link ( Figure 1 User-side devices include Bluetooth temperature measurement remote controls, remote control dongles, smart set-top boxes or smart TVs, and the temperature and humidity collection and reporting APK software installed on the set-top box or TV. The platform-side software platform for temperature and humidity collection, also known as the data collection platform, is deployed on a server. The intermediate transmission link can utilize various access methods, including broadcast and television networks, internet access, or dedicated links from telecommunications operators, based on the specific project implementation scenario.

[0030] The user-side Bluetooth thermometer remote controller has a temperature measurement chip installed on its motherboard. This chip is a temperature-measuring semiconductor chip. Heat dissipation holes are located on the remote controller housing, corresponding to the location where the temperature measurement chip is installed.

[0031] The Bluetooth temperature measurement remote control of the present invention is a Bluetooth remote control product with an onboard temperature measurement chip. In addition to supporting traditional Bluetooth / infrared remote control operation and voice transmission functions, the remote control supports temperature and humidity measurement at a preset collection period (such as 15 minutes) and the function of reporting data. The sensor position is fully considered when the remote control PCB is laid out. It needs to be away from the battery and heat-generating components without affecting the original function of the remote control. The window hole design is used in the shell design to minimize various interferences and influences from the external environment to ensure the accuracy of the collected data ( Figure 2 ).

[0032] A method for measuring room temperature based on a Bluetooth remote control and a set-top box, the method comprising the following steps: S1: The Bluetooth temperature measuring remote control detects temperature and / or humidity. If the detection is successful, the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel; S2: After receiving the data from the Bluetooth temperature measurement remote control, the remote control Dongle stores the data in the flash and array, waiting for the smart TV or smart set-top box with temperature and / or humidity collection and reporting functions to obtain it; S3: A smart TV or smart set-top box with temperature and / or humidity collection and reporting capabilities obtains temperature and / or humidity data through a remote control dongle and uploads it to the platform-side device through an intermediate transmission link device.

[0033] The measurement method of the room temperature measurement system of the present invention mainly collects temperature data through the Bluetooth temperature measurement remote control and sends it to the remote control Dongle at regular intervals. The remote control Dongle stores the received temperature and humidity data and then uploads it to the data acquisition platform through the temperature measurement software installed in the smart TV or set-top box. The specific work flow is shown in Figure 3 .

[0034] To measure temperature and humidity using the room temperature measurement system of the present invention, you must first install the temperature measurement software on a smart TV, smart set-top box, or other smart terminal device. This software is a customized terminal software package developed based on the smart terminal device's operating system, typically in the form of an APK file. Then, plug the USB communication adapter (remote control dongle) provided with the remote control into the smart TV or smart set-top box. This device is a standard USB device with an integrated HID standard protocol.

[0035] The Bluetooth temperature-measuring remote control performs temperature and humidity checks at regular intervals (e.g., 15 minutes). Upon successful detection, the remote control dongle transmits the data via Bluetooth. Upon receiving the temperature and humidity notification data from the Bluetooth temperature-measuring remote control, the remote control dongle stores the data in flash memory and an array, waiting for access by the temperature measurement software in smart terminals such as TVs or set-top boxes. The set-top box's temperature measurement software obtains the temperature and humidity data from the remote control dongle via a USB interface and uploads it to the data collection platform. If further data is needed, the data collection platform reports the data again using methods supported by other business platforms of the heating company (such as API integration, data pull, and FTP file synchronization).

[0036] In step S1 of the measurement method, the process in which the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle through the Bluetooth channel is provided with an intermittent wake-up method based on BLE; BLE is a Bluetooth low energy technology, which is based on the intermittent wake-up method of BLE: after the Bluetooth temperature measurement remote control is connected, it will remain in a constant connection state until it is in standby for 2.5 hours or the remote control Dongle actively disconnects, then it will enter sleep mode. At this time, the Bluetooth temperature measurement remote control can be woken up by pressing a button and a broadcast of the connection is sent back; when the Bluetooth temperature measurement remote control is disconnected from the remote control Dongle, the Bluetooth temperature measurement remote control will wake up every 15 minutes, collect temperature and / or humidity data, and send the temperature and / or humidity data to the remote control Dongle by broadcasting. After the data is sent, the Bluetooth temperature measurement remote control will enter sleep mode again. For details, see Figure 4 .

[0037] In step S1 of the measurement method, the process in which the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel is provided with a method for adjusting the frequency of dynamic temperature and humidity data reporting; The method for adjusting the frequency of dynamic temperature and humidity data reporting is as follows: Under factory default conditions, when the Bluetooth temperature measuring remote control is connected to the remote control Dongle, temperature and humidity data will be collected every 15 minutes. After successful collection, it will be transmitted to the remote control Dongle via notif for storage; The Bluetooth temperature measurement remote control can adaptively adjust the data collection and reporting interval according to the environmental change rate or user activity status, balancing accuracy and power consumption. The specific implementation method is as follows (see Figure 5 ): M1 temperature measurement: Carry out 4 measurements according to the initial 15-minute cycle. Each time the measurement time comes, perform the temperature measurement operation and add the measured temperature to the temperature history data list; M2 Temperature change judgment: Starting from the fifth measurement, the temperature value of this measurement is compared with the average of the previous four measurements, and the absolute value of the difference between the two is calculated. If the absolute value of the difference is greater than 5°C, it is considered that a sudden temperature change has occurred, and the measurement cycle is shortened to 7.5 minutes; M3 remote control usage frequency judgment: Check the number of times the Bluetooth temperature measurement remote control is used within 15 minutes. If the number of uses is greater than 10 times, it is determined that the Bluetooth temperature measurement remote control is in a high-frequency use scenario, that is, the physical location of the Bluetooth temperature measurement remote control is likely to have changed. The measurement cycle is also shortened to 7.5 minutes. M4 comprehensive judgment: If the Bluetooth temperature measurement remote control is used 0 times within 15 minutes and the number of data in the temperature history data list is greater than 1, calculate the average absolute value of the difference between adjacent temperature values ​​in the temperature history data. If the average value is less than 1°C, the threshold can be adjusted according to the actual situation. It is considered that the temperature change is not significant and the measurement period is extended to 30 minutes. M5 cycle adjustment post-processing: Regardless of whether the measurement cycle is extended or shortened, after the adjustment is completed, the number of remote control usages will be reset to 0. If the measurement cycle is extended, to avoid excessive historical data usage, the temperature history data list will retain the most recent 4 data items. M6 loop execution: Repeat steps 1-5 above according to the adjusted measurement cycle to adaptively adjust the data reporting interval based on the rate of environmental change and user activity status.

[0038] In step S2 of the measurement method, the remote control dongle has a reserved protocol interface to obtain multi-party data and has an abnormal temperature measurement judgment function based on multi-terminal data; the remote control dongle complies with the standard USB HID device specification and can be used as a standard USB input device after being inserted into a smart TV or smart set-top box. The temperature transmission between the remote control dongle and the remote control adopts the Modbus protocol.

[0039] The remote control dongle has a reserved protocol interface for acquiring data from multiple sources and can detect abnormal temperature measurements based on this data. The dongle also supports data reporting from a third-party temperature and humidity sensor. This data is then verified using the Modbus protocol, and the temperature and humidity data can be extracted upon successful verification.

[0040] The specific judgment process of the abnormal temperature measurement judgment function based on multi-terminal data is as follows (see Figure 6 ): P1: Remote controller Dongle is powered on and started; P2: Device connection judgment: The remote control Dongle determines whether a third-party device is connected. If a third-party device is connected, its data is obtained through the reserved protocol interface; if no third-party device is connected, the temperature data of the matching Bluetooth temperature measurement remote control is directly obtained; P3: Third-party data verification: After obtaining data from a third-party device, verify the data based on the Modbus protocol. If the verification succeeds, extract the temperature and humidity data of the third-party device; if the verification fails, record an error log and ignore the data. P4: Data integration: Whether it is temperature and humidity data obtained from third-party devices or directly obtained from the Bluetooth temperature measurement remote control, it will be integrated; P5: Abnormal Judgment: First, determine whether the temperature difference between the third-party device and the Bluetooth temperature measuring remote control exceeds 3°C. If it exceeds 3°C, further determine whether the temperature of the third-party device has changed by more than 5°C compared to 15 minutes ago. If so, it is defined as abnormal data, and reporting stops and abnormal information is recorded. If the temperature of the third-party device has not changed by more than 5°C compared to 15 minutes ago, then determine whether the temperature of the remote control has changed by more than 5°C compared to 15 minutes ago. If so, it is also defined as abnormal data, and reporting stops and abnormal information is recorded. If it does not exceed, the data is determined to be normal and reporting is carried out. If the temperature difference between the third-party device and the remote control does not exceed 3°C, the data is directly determined to be normal and reporting is carried out.

[0041] The temperature measurement software installed on the smart TV or smart set-top box of the present invention has the following functions: 1. The temperature measurement software starts automatically in the background when the random top box is started.

[0042] 2. The temperature measurement software obtains the corresponding system permissions of the set-top box and can directly obtain the temperature and humidity data periodically reported by the remote control through the Bluetooth protocol.

[0043] 3. The software supports docking with the remote control Dongle to obtain temperature and humidity information.

[0044] 4. The temperature measurement software has OTA upgrade capabilities.

[0045] After the temperature measurement software collects temperature and humidity data, it must transmit the data to a designated data collection platform via a cable TV network, the internet, or an IPTV network. This data is reported by the temperature measurement software using the data collection platform's API. Software modifications must be tailored to the specific platform's needs.

[0046] The Bluetooth temperature measurement remote control of the present invention also has button and voice data sending functions. In addition to supporting the temperature measurement function, the Bluetooth temperature measurement remote control product designed by the present invention can simultaneously realize all the functions of the voice remote control without being interfered with by the temperature measurement function.

[0047] When the user presses a button on the Bluetooth temperature measurement remote control, it determines whether it is connected to the remote control Dongle device. When the Bluetooth temperature measurement remote control determines that it is currently connected to the remote control Dongle, it sends the HID key value corresponding to the button to the smart terminal device; when the Bluetooth temperature measurement remote control determines that it is not connected to the remote control Dongle, the Bluetooth temperature measurement remote control uses the infrared protocol to send the infrared key value through the infrared transmitter.

[0048] When the user presses the voice button of the Bluetooth temperature measurement remote control, the Bluetooth temperature measurement remote control enters the sound pickup state. After the microphone picks up the sound, it encodes and compresses the audio data and transmits it to the remote control Dongle after compression; after the remote control Dongle receives the audio data, it decompresses and decodes the audio data, generates PCM data and transmits it to the smart terminal device.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The method for measuring room temperature based on a Bluetooth remote controller and a set-top box according to claim 7, wherein: In step S1, the process in which the Bluetooth temperature measuring remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel is provided with a method for adjusting the frequency of dynamic temperature and humidity data reporting; The method for adjusting the reporting frequency of dynamic temperature and humidity data is as follows: in the factory default state, when the Bluetooth temperature measurement remote control is connected to the remote control Dongle, temperature and humidity will be collected every 15 minutes. After the collection is successful, it will be transmitted to the remote control Dongle for storage via notif; The Bluetooth temperature measurement remote control can adaptively adjust the data collection and reporting interval according to the environmental change rate or user activity status, balancing accuracy and power consumption. The specific implementation method is as follows: M1 temperature measurement: Carry out 4 measurements according to the initial 15-minute cycle. Each time the measurement time comes, perform the temperature measurement operation and add the measured temperature to the temperature history data list; M2 Temperature change judgment: Starting from the fifth measurement, the temperature value of this measurement is compared with the average of the previous four measurements, and the absolute value of the difference between the two is calculated. If the absolute value of the difference is greater than 5°C, it is considered that a sudden temperature change has occurred, and the measurement cycle is shortened to 7.5 minutes; M3 remote control usage frequency judgment: Check the number of times the Bluetooth temperature measurement remote control is used within 15 minutes. If the number of uses is greater than 10 times, it is determined that the Bluetooth temperature measurement remote control is in a high-frequency use scenario, that is, the physical location of the Bluetooth temperature measurement remote control is likely to have changed. The measurement cycle is also shortened to 7.5 minutes. M4 comprehensive judgment: If the Bluetooth temperature measurement remote control is used 0 times within 15 minutes and the number of data in the temperature history data list is greater than 1, calculate the average absolute value of the difference between adjacent temperature values ​​in the temperature history data. If the average value is less than 1°C, the threshold can be adjusted according to the actual situation. It is considered that the temperature change is not significant and the measurement period is extended to 30 minutes. M5 cycle adjustment post-processing: Regardless of whether the measurement cycle is extended or shortened, after the adjustment is completed, the number of remote control usages will be reset to 0. If the measurement cycle is extended, to avoid excessive historical data usage, the temperature history data list will retain the most recent 4 data items. M6 loop execution: Repeat steps 1-5 above according to the adjusted measurement cycle to adaptively adjust the data reporting interval based on the rate of environmental change and user activity status.

10. The room temperature measurement method based on a Bluetooth remote controller and a set-top box according to claim 7, characterized in that: In step S2, the remote control Dongle has a function of reserving a protocol interface to obtain multi-party data and has a function of abnormal temperature measurement and judgment based on multi-terminal data; The specific judgment process of the abnormal temperature measurement judgment function based on multi-terminal data is as follows: P1: Remote controller Dongle is powered on and started; P2: Device connection judgment: The remote control Dongle determines whether a third-party device is connected. If a third-party device is connected, its data is obtained through the reserved protocol interface; if no third-party device is connected, the temperature data of the matching Bluetooth temperature measurement remote control is directly obtained; P3: Third-party data verification: After obtaining data from a third-party device, verify the data based on the Modbus protocol. If the verification is successful, extract the temperature and humidity data of the third-party device; If the verification fails, an error log is recorded and the data is ignored; P4: Data integration: Whether it is temperature and humidity data obtained from third-party devices or directly obtained from the Bluetooth temperature measurement remote control, it will be integrated; P5: Abnormal Judgment: First, determine whether the temperature difference between the third-party device and the Bluetooth temperature measuring remote control exceeds 3°C. If it exceeds 3°C, further determine whether the temperature of the third-party device has changed by more than 5°C compared to 15 minutes ago. If so, it is defined as abnormal data, and reporting stops and abnormal information is recorded. If the temperature of the third-party device has not changed by more than 5°C compared to 15 minutes ago, then determine whether the temperature of the remote control has changed by more than 5°C compared to 15 minutes ago. If so, it is also defined as abnormal data, and reporting stops and abnormal information is recorded. If it does not exceed, the data is determined to be normal and reporting is carried out. If the temperature difference between the third-party device and the remote control does not exceed 3°C, the data is directly determined to be normal and reporting is carried out.
