[0018] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] As Figure 1 and Figure 2 shown, an intelligent TV for automatically warning of the spontaneous combustion of a TV according to the present invention includes an intelligent TV housing. A TV function module, a controller module, and a sensor module are provided inside the intelligent TV housing. The controller module includes a control circuit board. A core control unit and a current sensor are provided on the control circuit board. The sensor module includes a plurality of temperature sensors. The temperature sensors are electrically connected to the control circuit board. The core control unit can receive the information data of the current sensor and the temperature sensors.

[0020] Through the setting of the current sensor, the current data situation on the control circuit board can be directly detected, and the core control unit is cooperated to read the current data information. When abnormal current data is found, such as sudden increase or decrease, the TV function module is controlled to give an alarm. Through the combination of the current sensor and the temperature sensor, the accuracy of the alarm is effectively improved.

[0021] The model of the current sensor is ACS712-05B, which converts the analog signal into a digital signal and transmits it to the core control unit of the control circuit board for processing. A power supply pin VCC, a current input pin, a current output pin VIOUT, a ground pin GNG, and a filter pin FILTER are provided on the current sensor.

[0022] The power supply pin VCC is connected to a power supply. The power supply voltage of the circuit is +5V.

[0023] The current input pin is connected to a circuit with a current to be measured. The number of current input pins is four, two ip+ and two ip-, which are connected to the current loop to be measured. After the current flows through the current sensor, a magnetic field will be induced and a voltage signal will be generated.

[0024] The current output pin VIOUT is connected to a first resistor R F The first resistor R FThe other end is connected to a diode D1 and a second resistor R1. The other end of the second resistor R1 is grounded. The other end of the diode D1 is connected to an analog-to-digital converter and a first capacitor C1. The other end of the first capacitor C1 is grounded. The filtering pin FILTER is connected to a second capacitor C F , and the other end of the second capacitor C F is grounded, and the grounding pin GNG is grounded.

[0025] The current output pin VIOUT outputs an analog voltage signal proportional to the input current. This signal passes through a filtering circuit composed of a first resistor R F and a second capacitor C F to filter out high-frequency noise and smooth the output signal.

[0026] The resistance value of the first resistor R F is 2KΩ, and the capacitance value of the second capacitor C F is 1nf.

[0027] The filtering pin FILTER is grounded through the second resistor R1 to further smooth the signal. The resistance value of the second resistor R1 is 10KΩ.

[0028] The diode D1 is used to perform half-wave rectification on the analog signal output by the sensor. Its function is to ensure that the output signal is unipolar before entering the analog-to-digital converter, which is suitable for digital processing.

[0029] The first capacitor C1 is used to filter the rectified signal, smooth the signal fluctuation, and ensure the signal stability.

[0030] The power supply pin VCC is also connected to a bypass capacitor. The other end of the bypass capacitor is grounded. The bypass capacitor is used for power supply decoupling, reducing power supply noise, and providing a stable power supply voltage.

[0031] The model of the analog-to-digital converter is ADC0804. The analog-to-digital converter is connected to the core control unit. The analog-to-digital converter receives the signal after rectification and filtering, converts the analog voltage signal into a digital signal, which is convenient for subsequent digital processing and acquisition by the core control unit.

[0032] The core control unit assigns different weights according to the importance of each sensor and the reliability of the detection results through the existing weighted algorithm.

[0033] The core control unit is equipped with a multi-level early warning mechanism, and issues early warning signals respectively according to the degree of abnormal situations detected. The low-level early warning can prompt the user to pay attention to possible risks, while the high-level early warning directly triggers safety measures such as shutting down.

[0034] The core control unit collects data of the current sensor, temperature sensor, and smoke sensor once every minute.

[0035] For the abnormal detection of current fluctuations, the existing sliding window algorithm is combined with the set standard deviation for judgment. The core control unit stores the most recent current values (such as the most recent week) through a storage module, and calculates the mean and standard deviation of the current values within the sliding window.

[0036] When a new current value enters the window, calculate its difference from the window mean. If the difference exceeds a certain set threshold (such as 2 times the standard deviation), it is determined as an abnormal fluctuation, effectively detecting sudden current changes and giving an early warning of potential spontaneous combustion risks in a timely manner.

[0037] The core control unit is a microprocessor, and the MediaTek MT9603 series microprocessor is selected.

[0038] The model of the temperature sensor is DS18B20, which is connected to the core control unit of the control circuit board through the IIC bus to monitor the internal temperature of the TV in real time.

[0039] The sensor module also includes multiple smoke sensors, and the smoke sensors are electrically connected to the control circuit board.

[0040] Through the setting of the smoke sensor, the early warning ability of the smart TV for spontaneous combustion can be further improved. When smoke is detected inside the smart TV, an early warning is given immediately.

[0041] By setting thresholds and alarm rules for the three different sensors, the core control unit can more accurately judge abnormal situations and give early warnings in advance, effectively improving the accuracy and early warning ability of the TV for spontaneous combustion warning, overcoming the limitations of the existing technology, and providing a safer use guarantee for users.

[0042] The core control unit is set with a multi-level early warning mechanism, and early warning signals are sent respectively according to the degree of abnormal situations detected.

[0043] Low-level early warning: The system triggers a low-level early warning, prompting the user to check the TV status, such as by popping up a prompt box on the TV.

[0044] Medium-level early warning: The system triggers a medium-level early warning. The TV pops up a window to prompt the user to immediately check the TV and prepare to take further measures, and at the same time, the TV plays a beeping music.

[0045] High-level early warning: Trigger a high-level early warning and execute the automatic power-off function to prevent the further spread of the fire.

[0046] Through the existing weighted algorithm, different weights are set for multiple sensors. The core control unit comprehensively considers the data of multiple sensors, improves the accuracy and reliability of the early warning, and avoids the occurrence of false alarms, missed alarms or late alarms.

[0047] The TV function module includes a voice input module, a display screen module, and a sound module. The smart TV is voice-controlled through the voice input module, the content of the smart TV is displayed through the display screen module, and the corresponding content and sound are played through the sound module in cooperation with the display screen module.

[0048] As can be seen from the above, the beneficial effects of the present utility model are as follows: By adopting its system, the problem of inaccurate early warning for spontaneous combustion in smart TVs in the prior art can be effectively solved. By using this structural setting scheme and adding a temperature sensor for current monitoring in the smart TV, the temperature sensor is combined with the current sensor, which can effectively improve the accuracy of the early warning. After detecting abnormal current, an early warning is issued, which is beneficial to improving the competitiveness of the product.

[0049] The above-mentioned specific implementation manners are the preferred implementation manners of the present utility model, and do not limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
