Description

Technical Field

[0001] This utility model belongs to the field of temperature monitoring, and also to the field of cable TV, IPTV and smart TV network applications. Specifically, it relates to a room temperature measurement system based on a Bluetooth remote control and a set-top box. Background Technology

[0002] In recent years, the heating industry has been transforming from simple centralized heating to refined and intelligent services. Temperature and humidity data collection, as a fundamental data source, has become increasingly important. On the one hand, traditional manual door-to-door temperature measurement methods are inefficient and subjective, making them insufficient to meet the needs of large-scale heating users. This has prompted the industry to actively explore automated temperature and humidity data collection technologies.

[0003] Currently, wireless IoT technology is booming, with 4G, 5G, and WiFi technologies being partially applied to temperature and humidity sensor devices. This has led to products such as wall-mounted thermometers and hygrometers with built-in communication modules, 86-type switch panels, and wall socket panels, enabling real-time acquisition and remote transmission of indoor temperature and humidity data. However, existing solutions have certain issues regarding hardware cost, network stability, equipment installation difficulty, and long-term equipment maintenance, hindering large-scale business deployment.

[0004] Among them, wall-mounted thermometers and hygrometers with built-in communication modules typically have built-in 4G or 5G communication modules, enabling them to collect indoor temperature and humidity data in real time and transmit the data back to the backend server via wireless network. The main advantage of this solution is that it can be flexibly installed in suitable indoor locations for accurate room temperature measurement. However, it requires the integration of components such as communication modules, temperature sensing devices, and displays, and data transmission incurs data charges. Transmission can be unstable when encountering signal obstruction, and the thermometer's installation location is not fixed, resulting in low accuracy in temperature acquisition and higher maintenance difficulty.

[0005] Additionally, the 86-type switch panel or 86-type power panel with a built-in communication module, which integrates temperature and humidity sensors, can collect and transmit temperature and humidity information without occupying extra space, utilizing its built-in 4G, 5G, or WiFi communication capabilities. Its advantages include direct replacement of existing switch panels without power supply issues and minimal impact on the user's interior design. However, it also has disadvantages such as high operating costs, high hardware costs, inaccurate measurements due to limited switch panel area, low transmission stability, and difficult installation.

[0006] Overall, the field of temperature and humidity data acquisition in the urban heating industry is still in a stage of continuous development and improvement, and there is an urgent need for more cost-effective, stable and adaptable innovative solutions to meet the growing service demands. Utility Model Content

The system is used in conjunction with a smart TV or smart TV set-top box in the home of a heating user to achieve room temperature acquisition and data transmission. At the same time, the temperature and humidity acquisition function does not affect other functions of the remote control such as infrared operation, Bluetooth operation, and voice control of the set-top box. This achieves 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 objectives, this utility model provides the following technical solution: a room temperature measurement system based on a Bluetooth remote control and a set-top box, including user-side devices, wherein the user-side devices include: a Bluetooth temperature measurement remote control, a remote control Dongle, and a smart TV or smart set-top box with temperature and / or humidity acquisition and reporting functions.

Ordinary users can easily complete the installation, reducing installation difficulty and time costs.

[0017] 3. Strong guarantee of communication stability: Compared with existing solutions based on 4G, 5G and WiFi, which are subject to interference from factors such as signal and traffic, this utility model utilizes the fixed network channel of smart TVs or set-top boxes to avoid signal fluctuations and traffic limitations, ensuring stable transmission of temperature and humidity data.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a room temperature measurement system based on a Bluetooth remote control and a set-top box, including user-side devices, which include: a Bluetooth temperature measuring remote control, a remote control dongle, and a smart TV or smart set-top box with temperature and / or humidity acquisition and reporting functions.

[0031] The room temperature measurement system also includes intermediate transmission link equipment; the intermediate transmission link equipment is one or a combination of broadcast television network equipment, Internet access equipment, and dedicated link equipment of telecommunications operators.

[0032] 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.

[0033] This utility model's room temperature measurement system is designed for heating companies to measure and collect temperature data. It works in conjunction with smart TVs or smart TV set-top boxes in households to collect and transmit room temperature data. Simultaneously, the temperature and humidity collection function does not interfere with other functions of the remote control, such as infrared operation, Bluetooth operation, and voice control of the set-top box.

[0034] This utility model mainly comprises three parts: the user side, the platform side, and the intermediate transmission link. Figure 1 The user-side devices include Bluetooth temperature-measuring remote controls, dongle remote controls, smart set-top boxes, or smart TVs. The platform side consists of a temperature and humidity acquisition platform deployed on a server, i.e., a data acquisition platform. The intermediate transmission links can utilize various access methods, such as broadcast television networks, internet access, or dedicated links from telecommunications operators, depending on the specific project implementation scenario.

[0035] The Bluetooth temperature measurement remote control in the user-side device has a temperature measurement chip installed on its main board. This temperature measurement chip is a temperature-sensing semiconductor chip. The remote control casing has ventilation holes corresponding to the location where the temperature measurement chip is installed.

[0036] This utility model relates to a Bluetooth temperature measurement remote control product with an onboard temperature measurement chip. In addition to supporting traditional Bluetooth / infrared remote control operation and voice transmission, this remote control supports temperature and humidity measurement at preset acquisition intervals (e.g., 15 minutes) and data reporting. The PCB layout of the remote control carefully considers the sensor location, ensuring it is kept away from the battery and heat-generating components without affecting the original functions of the remote control. The casing design incorporates a window opening to minimize interference and influence from the external environment, ensuring the accuracy of the acquired data. Figure 2 ).

[0037] This invention discloses a method for measuring room temperature using a Bluetooth remote control and a set-top box. The method includes the following steps:

[0038] S1: The Bluetooth temperature measurement remote control detects temperature and / or humidity. After successful detection, the Bluetooth temperature measurement remote control reports the temperature and / or humidity data to the remote control Dongle via the Bluetooth channel.

[0039] S2: After receiving the data from the Bluetooth temperature measuring remote control, the Dongle remote control stores the data in flash and array, waiting for the smart TV or smart set-top box with temperature and / or humidity acquisition and reporting functions to acquire it.

[0040] S3: Smart TVs or smart set-top boxes with temperature and / or humidity acquisition and reporting functions acquire temperature and / or humidity data via the remote control dongle and upload it to the platform-side device through an intermediate transmission link device.

[0041] The room temperature measurement system of this invention mainly uses a Bluetooth temperature remote control to collect temperature data and periodically send it to the remote control (Dongle). The remote control (Dongle) stores the received temperature and humidity data and then uploads it to a data acquisition platform via a temperature measurement system installed in a smart TV or set-top box. The specific workflow is described below. Figure 3 .

[0042] The Bluetooth temperature-sensing remote control performs temperature and humidity checks at regular intervals (e.g., every 15 minutes). Upon successful detection, it reports the temperature and humidity data to the remote control's dongle device via Bluetooth. The dongle device receives the temperature and humidity notification data from the Bluetooth remote control, stores the data in flash memory and an array, and awaits retrieval from smart terminals such as TVs or set-top boxes. The set-top box obtains the temperature and humidity data from the dongle via USB and uploads it to the data acquisition platform. If further requirements arise, the data acquisition platform uses methods supported by other business platforms of the heating company (such as API integration, data retrieval, FTP file synchronization, etc.) to report the data again.

[0043] In step S1 of the measurement method, the process of the Bluetooth temperature remote control reporting temperature and / or humidity data to the remote control Dongle via the Bluetooth channel is equipped with a BLE-based intermittent wake-up method.

[0044] BLE is Bluetooth Low Energy technology, which uses an intermittent wake-up method: After the Bluetooth temperature remote control is connected, it will remain connected until 2.5 hours of standby or the remote control's dongle actively disconnects, at which point it will enter sleep mode. At this time, the Bluetooth temperature remote control can be woken up by pressing a button and will send a reconnection broadcast. When the Bluetooth temperature remote control and the remote control dongle are disconnected, the Bluetooth temperature remote control will wake up every 15 minutes, collect temperature and / or humidity data, and broadcast the temperature and / or humidity data to the remote control dongle. After sending the data, the Bluetooth temperature remote control will enter sleep mode again. See details... Figure 4 .

[0045] In step S1 of the measurement method, the Bluetooth temperature remote control reports temperature and / or humidity data to the remote control dongle via the Bluetooth channel, and a method for adjusting the dynamic temperature and humidity data reporting frequency is set.

[0046] The method for adjusting the dynamic temperature and humidity data reporting frequency is as follows: In the factory default state, when the Bluetooth temperature measuring remote control and the remote control dongle are connected, temperature and humidity will be collected every 15 minutes. After successful collection, the data will be transmitted to the remote control dongle for storage via NOTIF.

[0047] The Bluetooth temperature measurement remote control can adaptively adjust the data acquisition and reporting interval according to the rate of environmental change or user activity, balancing accuracy and power consumption. The specific implementation method is (see...). Figure 5 ):

[0048] M1 Temperature Measurement: Perform 4 measurements in an initial 15-minute cycle. At each measurement time, perform the temperature measurement operation and add the measured temperature to the temperature history data list.

[0049] M2 Temperature Change Judgment: Starting from the 5th measurement, compare the temperature value of this measurement with the average of the previous 4 measurements, calculate the absolute value of the difference between the two. If the absolute value of the difference is greater than 5℃, it is considered that a sudden temperature change has occurred, and the measurement cycle is shortened to 7.5 minutes.

[0050] 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 times it is used is greater than 10, it is determined that the Bluetooth temperature measurement remote control is in a high-frequency usage scenario, that is, the physical position of the Bluetooth temperature measurement remote control is likely to change. Similarly, the measurement cycle is shortened to 7.5 minutes.

[0051] M4 Comprehensive Judgment: If the Bluetooth temperature 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 of the absolute values ​​of the differences between adjacent temperature values ​​in the temperature history data. If the average value is less than 1℃, the threshold can be adjusted according to the actual situation. Then it is considered that the temperature change is not significant, and the measurement period is extended to 30 minutes.

[0052] M5 Post-Adjustment Processing: Regardless of whether the measurement cycle is extended or shortened, after the adjustment is completed, the number of times the remote control is used will be reset to 0. If the measurement cycle is extended, in order to avoid excessive resource consumption by historical data, the most recent 4 data entries will be retained in the temperature history data list.

[0053] 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.

[0054] In step S2 of the measurement method, the remote control Dongle has a reserved protocol interface to acquire data from multiple parties and has an abnormal temperature 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 plugged 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.

[0055] The Dongle remote control has a reserved protocol interface to acquire data from multiple sources and features an anomaly temperature detection function based on multi-terminal data. The Dongle's reserved protocol interface also supports acquiring data reports from another third-party device equipped with temperature and humidity sensors. It performs data verification based on the Modbus protocol, and extracts the temperature and humidity data upon successful verification.

[0056] The specific judgment process of the abnormal temperature measurement judgment function based on multi-terminal data is as follows (see...). Figure 6 ):

[0057] P1: Power on / start remote control (Dongle);

[0058] P2: Device connection determination: 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 measuring remote control is obtained directly.

[0059] P3: Third-party data verification: After obtaining data from a third-party device, the data is verified based on the Modbus protocol. If the verification is successful, the temperature and humidity data of the third-party device are extracted; if the verification fails, an error log is recorded and the data is ignored.

[0060] P4: Data Integration: Whether it is temperature and humidity data obtained from third-party devices or temperature and humidity data obtained directly from Bluetooth temperature remote controls, it will be integrated.

[0061] P5: Anomaly Detection: First, determine if the temperature difference between the third-party device and the Bluetooth temperature remote control exceeds 3℃. If it exceeds 3℃, further determine if the temperature change of the third-party device compared to 15 minutes ago exceeds 5℃. If it does, it is defined as abnormal data, reporting is stopped, and the abnormal information is recorded. If the temperature change of the third-party device compared to 15 minutes ago does not exceed 5℃, then determine if the temperature change of the remote control compared to 15 minutes ago exceeds 5℃. If it does, it is also defined as abnormal data, reporting is stopped, and the abnormal information is recorded. If it does not exceed 5℃, the data is considered normal and reporting continues. If the temperature difference between the third-party device and the remote control does not exceed 3℃, the data is directly considered normal and reporting continues.

[0062] The Bluetooth temperature measurement remote control of this utility model also has button and voice data transmission functions. In addition to supporting the temperature measurement function, the Bluetooth temperature measurement remote control product designed by this utility model can simultaneously realize all the functions of a voice remote control without being interfered with by the temperature measurement function.

[0063] When a user presses a button on the Bluetooth temperature measurement remote control, the system checks if it is connected to the remote control dongle device. If 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 press to the smart terminal device. If the Bluetooth temperature measurement remote control determines that it is not connected to the remote control dongle, it uses an infrared protocol to send the infrared key value through an infrared transmitter.

[0064] When the user presses the voice button on the Bluetooth temperature measurement remote control, the remote control enters the sound pickup state. After the microphone picks up the sound, it encodes and compresses the audio data, and then transmits the compressed data to the remote control's dongle. After receiving the audio data, the remote control's dongle decompresses and decodes the audio data, generates PCM data, and then transmits it to the smart terminal device.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
