[0033] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] Those skilled in the art know that the embodiments of the present invention can be implemented as a system, device, apparatus, method or computer program product. Therefore, the present invention can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0035] It should be noted that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0036] Reference below Figure 1 , Figure 1 This is a schematic diagram of the structure of an electric fireplace fault alarm system provided by an embodiment of the present invention. Figure 1 As shown, an electric fireplace fault alarm system includes:

[0037] A main power supply module, a controller module, a heating system module, an LED lighting control system module, a wall switch system module, and a fault detection and alarm control unit; wherein the controller module is used to control the normal operation and fault detection of the electric fireplace;

[0038] The fault detection and alarm control unit is used to control the LED lighting control system module and the wall switch system module to send an alarm signal based on the fault signal when an abnormality of the electric fireplace is detected;

[0039] Based on the controller module, the heating system module of the electric fireplace is controlled to run according to a predetermined program;

[0040] Based on the fault detection and alarm control unit, it includes:

[0041] Get the operating status of each module of the electric fireplace in real time;

[0042] An alarm is controlled based on a comparison result between the operating status and a preset safety parameter.

[0043] It should be noted that the modules in the system include the main power module, controller module, heating system module, LED light control system module, wall switch system module, and fault detection and alarm control unit. These modules work together to achieve safe operation of the electric fireplace. For example, the controller module is responsible for receiving signals from the fault detection unit and controlling the operation of the heating system module accordingly, while the LED light control system module and the wall switch system module provide visual and physical alarm indications when a fault is detected.

[0044] Preferably, the fault detection and alarm control unit may further include a microprocessor that runs a specific algorithm to analyze the data collected from each sensor and determine whether a fault exists. In addition, the system may be designed to have a self-diagnosis function and regularly check its own operating status to ensure the reliability of the alarm system. In terms of the alarm control strategy, multiple alarm levels may be set to trigger alarm signals of different intensities according to the severity of the fault.

[0045] In some embodiments, at least one thermistor sensor is further included to monitor the temperature status of the electric fireplace in real time.

[0046] It should be noted that the thermistor sensor is a device that uses the property that the resistance of a material changes with temperature to measure temperature. In this system, NTC (negative temperature coefficient) or PTC (positive temperature coefficient) type thermistors can be selected, and the number and layout of sensors can be determined according to the specific design and use environment of the electric fireplace. For example, sensors can be installed near the heating element of the electric fireplace, at the air outlet, and on key circuit boards to achieve comprehensive temperature control monitoring. The parameter setting of the sensor should ensure that its measurement range covers the lowest and highest temperatures that the electric fireplace may encounter, and the accuracy must meet safety requirements.

[0047] Preferably, the thermistor sensor can be connected to the controller module through a communication protocol such as I2C or SPI to achieve real-time transmission and processing of data. In terms of settings, thresholds can be set for sensor data, and when the detected temperature exceeds or falls below these thresholds, the system automatically triggers an alarm. In addition, the system can also dynamically adjust the operating state of the heating system by controlling the execution unit based on the data provided by the thermistor sensor to keep the electric fireplace working within a safe temperature range. More specifically, a temperature monitoring list can be set to record real-time data from different sensors, and when an abnormality is detected, the corresponding alarm color is displayed through the LED light control system module, such as red for overheating and blue for overcooling.

[0048] In some embodiments, the controller module includes a fault determination logic and a control execution unit;

[0049] The fault judgment logic is used to judge whether the temperature information collected by the thermistor sensor exceeds the safety range;

[0050] The control execution unit controls the fault detection and alarm control unit to issue an alarm according to the judgment result.

[0051] It should be noted that the fault judgment logic and control execution unit of the controller module are designed to realize intelligent analysis and response to the state of the electric fireplace. This part is the core of the system's intelligent decision-making, which can ensure that abnormal situations can be handled quickly and accurately when detected.

[0052] Specifically, the fault judgment logic can use a series of preset algorithms and thresholds to determine whether the temperature information collected by the thermistor sensor exceeds the safe range. For example, a temperature upper limit threshold can be set. Once the monitored temperature exceeds this value, the system will consider that there is a risk of overheating. The control execution unit triggers the corresponding alarm program by sending a control signal to the fault detection and alarm control unit based on the output result of the fault judgment logic. Parameter settings may include temperature thresholds, response times, etc., which need to be determined according to the specific usage scenarios and safety standards of the electric fireplace.

[0053] Preferably, the fault judgment logic can further include an evaluation of the temperature change rate and the temperature change acceleration to achieve more comprehensive fault detection. For example, the system can not only detect instantaneous high temperature, but also identify rapid temperature rise or fall trends, which may indicate potential fault risks. More specifically, an adaptive control algorithm can be designed that can dynamically adjust the temperature threshold according to the use history and environmental conditions of the electric fireplace to achieve more accurate fault judgment. In addition, the control execution unit can integrate a feedback mechanism to optimize the control strategy according to the system response and user operation after the alarm, thereby improving the system reliability and user experience.

[0054] In some embodiments, the fault detection and alarm control unit includes an audible and visual alarm and a remote communication module;

[0055] The sound and light alarm is used to emit sound and light signals when a fault is detected;

[0056] The remote communication module is used to transmit fault information to a remote monitoring center.

[0057] It should be noted that the composition of the fault detection and alarm control unit, especially the addition of the sound and light alarm and the remote communication module, is to provide a more intuitive warning when a fault occurs and ensure that the fault information can be conveyed to the user or other managers in a timely manner.

[0058] Specifically, the sound and light alarm may include one or more sirens and flashing lights, which are used to emit sound and light signals when a fault is detected to attract the attention of on-site personnel. The remote communication module is responsible for transmitting the fault information to the remote monitoring center, which is usually achieved through a wireless or wired network. For example, the remote communication module can use Wi-Fi, ZigBee, LoRa or other communication technologies. The specific technology to be selected depends on the use environment of the electric fireplace and the technical requirements of the remote monitoring center. Parameter settings may include communication frequency, data transmission format, error detection and correction mechanism, etc.

[0059] Preferably, the fault detection and alarm control unit can further integrate an intelligent analysis system that can predict potential faults based on the collected data patterns, rather than just sounding an alarm after a fault occurs. More specifically, a fault log recording function can be designed to record the type, time and processing results of each fault for future analysis and optimization. In addition, the remote communication module can be designed to support multiple communication protocols to adapt to different monitoring systems, or automatically switch to an alternate communication method when the primary communication method fails, thereby enhancing the reliability and flexibility of the system.

[0060] In some embodiments, the remote communication module uses a WIFI module to achieve data exchange with a remote monitoring center.

[0061] It should be noted that the remote communication module uses a WIFI module to achieve data exchange with the remote monitoring center, which means that the system has the ability to connect to a wireless network and can transmit fault information without being restricted by wiring.

[0062] Specifically, the WIFI module is a wireless communication hardware that complies with the IEEE 802.11 standard and is capable of wireless data transmission in the 2.4GHz or 5GHz frequency band. The module should be configured with appropriate firmware and software drivers to ensure compatibility with the electric fireplace control system and to be able to send data to a remote monitoring center through a secure network connection. Parameter settings may include the SSID (network name) of the WIFI network, password, data encryption method, and transmission rate.

[0063] Preferably, the remote communication module can integrate a status indicator light or provide an APP notification function on the mobile device so that the user can instantly understand the status of data transmission. More specifically, the WIFI module can be configured to support multiple security protocols, such as WPA2, to ensure the security of data transmission. In addition, considering the possible interference of wireless signals or network instability, the system can be designed to automatically try to reconnect or switch to a preset backup communication method, such as 4G / LTE network, when the WIFI connection fails to ensure the reliable transmission of fault information. A heartbeat mechanism can also be set up, that is, the remote communication module regularly sends status information to the remote monitoring center to confirm the validity of the connection.

[0064] In some embodiments, the controller module further includes a power failure detection unit;

[0065] The power failure detection unit is used to detect the status of the main power supply module and the auxiliary power supply module to ensure that a power failure alarm can be issued in time in the event of a power failure.

[0066] It should be noted that the power failure detection unit is to ensure that the electric fireplace can issue a warning in time when there is a problem with the power supply, thereby avoiding inconvenience or damage caused by the power supply problem.

[0067] Specifically, the power failure detection unit can be designed as an independent monitoring system, which can detect the status of the main power module and the auxiliary power module in real time. The unit can use voltage sensitive components, such as voltage monitoring chips, to detect whether the power supply voltage is within the normal range. If the power supply voltage is lower than the preset threshold, the power failure detection unit will trigger a power failure alarm and send a warning signal through the controller module. Parameter settings may include normal voltage range, voltage threshold of power failure alarm, alarm duration, etc.

[0068] Preferably, the power failure detection unit can be further integrated into the fault detection and alarm control unit to achieve centralized management and control. More specifically, the power failure detection unit can be designed to have a self-diagnosis function and perform regular self-checks to ensure that it functions properly. In addition, a user-configurable parameter can be set to allow the user to adjust the sensitivity of the power failure alarm according to the use environment of the electric fireplace and the stability of the power supply. An intelligent learning algorithm can also be designed to enable the power failure detection unit to optimize the alarm threshold based on historical power failure events to reduce false alarms.

[0069] In some embodiments, the power outage detection unit is connected to a power outage alarm system module to automatically trigger a power outage alarm when a power outage is detected.

[0070] It should be noted that the power failure alarm system module is a system specially designed to respond to power failure events. It may include one or more alarms, indicator lights and / or display screens to alert users when a power failure occurs. The module can be connected to the power failure detection unit through a relay or solid-state relay to ensure that the alarm program can be immediately activated when a power failure signal is detected. Parameter settings may include the response time of power failure detection, the duration of the alarm, the type of alarm signal, etc.

[0071] Preferably, the power outage alarm system module can be designed to have multiple alarm levels, providing alarm signals of different intensities according to the severity of the power outage. More specifically, the system can set a hierarchical alarm mechanism. For example, when the power supply voltage drops to a certain percentage of the normal value, a primary alarm is activated; if the voltage continues to drop or fails to recover for a long time, the system upgrades to a higher level of alarm. In addition, the system can also be designed to automatically send a notification to the user's mobile device when a power outage occurs, or automatically record the time and duration of the power outage event for subsequent analysis and maintenance. It is also possible to consider using a backup power supply, such as a battery, to ensure that the alarm system can still work normally when the main power supply is cut off.

[0072] In some embodiments, the controller module is also connected to the stepper motor system module to automatically cut off the power supply when a fault occurs.

[0073] It should be noted that the stepper motor system module is a device that accurately controls the on and off of the power supply. It consists of a stepper motor, a driver, and a control interface. A stepper motor is a motor that can accurately control the rotation angle by receiving a pulse signal. Its use in this system can ensure the accuracy and reliability of power cutoff. The controller module sends corresponding pulse signals to the stepper motor system module according to the instructions of the fault detection and alarm control unit to control the on and off of the power supply. Parameter settings may include pulse frequency, number of pulses, delay of power cutoff, etc.

[0074] Preferably, the stepper motor system module can be designed to have self-protection functions, such as overload protection, overheating protection, etc., to prevent damage to the motor or affect the safety performance of the system under abnormal circumstances. More specifically, the system can be designed with a feedback mechanism so that the stepper motor can return a signal of success or failure to the controller module after performing a power cut-off operation to ensure the accuracy of the operation. In addition, a manual reset or reset button can be set to allow the user to manually restore power or restart the system after the power is automatically cut off. It is also possible to consider designing a backup power switching mechanism so that when the main power is cut off, the system can automatically switch to the backup power supply to maintain the operation of key components.

[0075] In some embodiments, the following operations are performed to obtain the fault status of the electric fireplace: based on the real-time collected temperature T(t) of the electric fireplace, the temperature change rate is calculated. And the acceleration of temperature change

[0076] in, It represents the rate of change of temperature with time;

[0077] It indicates the rate of change of temperature over time;

[0078] Based on the temperature change rate and the acceleration of temperature change Calculate the failure risk index R(t):

[0079]

[0080] Among them, w1, w2, w3 are weight coefficients, is the maximum safety threshold of the temperature change rate;

[0081] When the fault risk index R(t) exceeds the preset fault risk threshold R threshold When the fault alarm is triggered.

[0082] It should be noted that the method of collecting the temperature of the electric fireplace in real time and calculating its rate of change and acceleration is to quantitatively evaluate the operating status of the electric fireplace and predict possible failure risks.

[0083] Specifically, the real-time collected temperature T(t) refers to the instantaneous measurement value of the temperature of the electric fireplace heating element or its surrounding environment in a continuous period of time. is the derivative of temperature with time, indicating how fast the temperature changes, while the acceleration of temperature change is the derivative of the temperature change rate, reflecting the rapidity of the temperature change trend. The calculation of these parameters involves numerical differentiation, which can be approximated by differential equations and sampled data. The failure risk index R(t) is a comprehensive indicator that measures the contribution of the temperature change rate and the acceleration of temperature change to the failure risk by assigning different weight coefficients w1, w2, and w3, and is related to the maximum safety threshold of the temperature change rate. Compare to determine current risk level.

[0084] Preferably, the calculation of the fault risk index R(t) can further consider more operating parameters, such as the working time of the heating element, the frequency of use of the electric fireplace, etc., to improve the accuracy of fault prediction. More specifically, an adaptive weight adjustment algorithm can be designed to dynamically adjust the values ​​of w1, w2, and w3 according to historical fault data and real-time operating status to achieve more accurate risk assessment. In addition, the system can set multiple fault risk thresholds R threshold , corresponding to different alarm levels and response measures, such as only recording and reminding for minor risks, and immediately triggering alarms and taking safety measures such as power off for high risks. It is also possible to consider introducing machine learning technology to identify failure modes through training models and improve the intelligence level of failure prediction.

[0085] In some embodiments, w1 can be set between 0.5 and 1, indicating a medium to high impact of the temperature change rate on the failure risk, w2 can be set between 0.1 and 0.5, indicating a low to medium impact of the temperature change acceleration on the failure risk. w3 can be set between 0.1 and 0.3, indicating a low impact of the square of the ratio of the temperature change rate to the safety threshold on the failure risk.

[0086] For example,

[0087] (Temperature change rate)

[0088] (Acceleration of temperature change)

[0089] (Maximum safety threshold of temperature change rate)

[0090]

[0091] R(t)=1.6+0.15+0.0889≈1.8389

[0092] If the preset failure risk threshold R threshold If it is set to 1.5, the value of R(t) exceeds the threshold and the system will trigger a fault alarm.

[0093] The above-mentioned embodiments of the present invention have the following beneficial effects: The design of the electric fireplace fault alarm system integrates a series of intelligent monitoring and automatic control functions, which can significantly improve the safety and reliability of the use of electric fireplaces. By real-time monitoring of the temperature changes of the electric fireplace and timely responding to abnormal conditions, the system can effectively prevent faults such as overheating and reduce the risk of accidents. In addition, the system can also quickly issue an alarm when a power outage or other fault occurs, reminding the user to take corresponding measures, thereby ensuring the safety of the user and extending the service life of the electric fireplace. In addition, the system can predict potential faults and issue warnings in advance by intelligently analyzing the operating data of the electric fireplace, which can not only avoid the inconvenience caused by the fault, but also reduce the cost and time of maintenance. By comprehensively using components such as temperature sensors, controller modules, fault detection and alarm control units, the system can provide users with a comprehensive, accurate and responsive electric fireplace safety protection solution. This intelligent monitoring and management method can further enhance the user experience and make the operation of the electric fireplace easier and safer.
