Description

Technical Field

[0001] The present application relates to the technical field of safety control of electric heaters, and in particular to a safety warning method, device, computer-readable storage medium and electronic device. Background Art

[0002] Electric oil heater is a kind of electric heating equipment widely used in winter. Its working principle is to heat the heat transfer oil through the electric heating pipe, and heat the surface of the oil heater through the circulation of the heat transfer oil in the closed system, so as to achieve the purpose of heating the air. Electric oil heater is commonly known as oil heater. The oil in the oil heater is called heat transfer oil, which is a heat transfer medium oil, which is a non-hazardous medium. After power is turned on, the oil temperature rises, thereby heating the surrounding air. The main function of the heat transfer oil is to transfer the heat generated by the electric heating pipe to the outside. The heat transfer oil is an efficient and energy-saving heating medium, which has the characteristics of high efficiency and energy saving, good thermal stability, good chemical stability, non-toxic, odorless, non-corrosive, long service life, and no environmental pollution. The use of heat transfer oil in electric oil heater can effectively improve the heating efficiency of electric oil heater, reduce the energy consumption of electric oil heater, and thus improve the energy-saving effect of electric oil heater. Compared with other traditional heating methods, electric oil heaters have the advantages of uniform heating, stable heat, suitable for long-term use, harmless to the human body, no electromagnetic radiation, no harmful gas generation, no combustion, no explosion, and no pollution.

[0003] Most oil heaters have a heating element outside the box. Users can use them without opening the box and can use them as long as they are powered on. However, the disadvantage is that it is difficult for users to detect when the product fails, which leads to safety hazards when users use the product. Existing oil heaters generally use a safety alarm module, which is generally installed inside the oil heater box. When the oil heater fails, the safety alarm module sends out a sound alarm or a light alarm. However, the sound alarm or light alarm signal can generally only be sent inside the oil heater box, and the sound alarm or light alarm signal is weak and difficult to detect. Therefore, the possibility of failure of the oil heater cannot be discovered in time, causing safety hazards.

[0004] Therefore, the oil-heating heater products in the prior art have potential safety hazards when in use, and when a fault occurs in the oil-heating heater product, the fault cannot be discovered and corrected in time, and no troubleshooting guidance can be provided, causing inconvenience in use.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] As introduced in the background technology, in the prior art, when an electric heater product fails, it is not possible to promptly detect and troubleshoot the fault. To solve the problem that when an electric heater product fails, it is not possible to promptly detect and troubleshoot the fault, the embodiments of the present application provide a safety warning method, device, computer-readable storage medium and electronic device.

[0025] In this embodiment, a security warning method running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 is a flow chart of a safety warning method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0027] Step S201, obtaining the usage time of the target heater, and outputting a first alarm signal when the usage time is greater than or equal to a preset time threshold, wherein the first alarm signal is used to warn that the target heater has reached a maximum usage time;

[0028] Specifically, the target heater in this embodiment is explained by taking the electric oil heater as an example. The existing electric oil heater already has an offline function, but it is often a simple entry and a fool-proof voice operation method. However, in actual use, users often report that when a fault occurs, they need to check the instructions or use the browser to search for related questions and answers, and the user experience is not good. In view of this, a voice safety broadcast logic is set to enhance human-computer interaction and troubleshooting purposes, thereby enhancing the user experience. First, when the user uses the whole machine, by turning on the machine, the chip will record the power-on time each time, and the power-off time will be recorded at the end. The length of use each time can be obtained and stored in the corresponding memory chip. The corresponding memory chip will accumulate and superimpose to obtain the usage time, and determine whether it exceeds the corresponding time limit (preset time threshold). If it exceeds the corresponding time limit, the corresponding program will execute the alarm instruction to output the first alarm signal.

[0029] Step S202, when the usage time is less than the preset time threshold, detecting whether there is a dangerous object in a preset area, wherein the dangerous object is an object that affects the safety of the target heater, and the preset area is an area including the target heater;

[0030] Specifically, when the usage time is less than the preset time threshold, it indicates that the usage time meets the requirement, and the user needs to be reminded whether there are other flammable, explosive and other dangerous items in the preset area next to the whole machine to ensure the safety of the surrounding area of ​​the whole machine. During use, if the user has needs (such as placing wet quilts and clothes on the surface for drying), it is easy to cause a fault alarm; if there is no alarm response, the whole machine will be used normally until the whole machine is shut down and the operation ends.

[0031] Step S203, when the dangerous goods exist in the preset area and a second alarm signal is output, a fault code is obtained, and a maintenance voice signal corresponding to the fault code is output, wherein the second alarm signal is used to at least warn that the dangerous goods exist in the preset area, the fault code is a code that characterizes the fault type of the target heater, and the maintenance voice signal indicates maintenance suggestions for the fault type.

[0032] Specifically, when there are dangerous items in the preset area, a fault alarm, i.e., a second alarm signal, is issued, and the user is prompted with the corresponding fault code where the problem is, and the user is guided to perform simple maintenance instructions through a maintenance voice signal.

[0033] Through this embodiment, the use time of the target heater is obtained, and when the use time is greater than or equal to the preset time threshold, the first alarm signal is output, wherein the first alarm signal is used to warn that the target heater has reached the maximum use time; when the use time is less than the preset time threshold, it is detected whether there are dangerous items in the preset area of ​​the target heater, wherein the dangerous items are items that affect the safety of the target heater; when there are dangerous items in the preset area and the second alarm signal is output, the fault code is obtained, and the maintenance voice signal corresponding to the fault code is output, wherein the second alarm signal is used to at least warn that there are dangerous items in the preset area, the fault code is a code that characterizes the fault type of the target heater, and the maintenance voice signal indicates the maintenance suggestion of the fault type. Compared with the prior art, when the electric heater product fails, the fault cannot be discovered and troubleshooted in time, and there are safety hazards, the present application issues an alarm when the target heater meets the corresponding alarm conditions, so as to warn that the target heater has safety hazards and timely perform fault discovery and elimination. Therefore, the safety of the electric heater can be improved.

[0034] In the specific implementation process, after the above step S203 outputs the maintenance voice signal corresponding to the fault code, the method further includes the following steps: Step S2031: Obtain the problem feedback result corresponding to the fault code, wherein the problem feedback result is a result indicating whether the fault has been resolved; Step S2032: When the problem feedback result indicates that the fault has been resolved, control the target heater to enter a normal working state; Step S2033: When the problem feedback result indicates that the fault has not been resolved, continue to output the second alarm signal. The method continues to control the heater through the above problem feedback result, so that the target heater can be controlled according to real-time feedback, thereby improving the safety of the heater. In a specific implementation, the above steps are intended to promptly and accurately convey the fault status to the user through an offline voice broadcast system, and guide the user to troubleshoot and resolve the fault, thereby improving the safety performance and user experience of the equipment.

[0035] Specifically, when the monitoring system of the oil heater detects an abnormality in the device, such as overheating or short circuit, a corresponding fault code will be generated. These fault codes are identifiers of internal errors in the device, and each code corresponds to a different problem. At this stage, the voice control system will read the fault code and obtain the problem feedback result corresponding to the code from the preset fault database. The problem feedback result contains a specific description of the fault and guidance information on how to troubleshoot and solve it. For example, if the fault code indicates overheating, the voice broadcast system will inform the user of the possible cause of the overheating of the device and suggest that the user check whether there are any obstructions around the device, whether it is placed in a poorly ventilated environment, and whether the recommended usage time has been exceeded. Once the user solves the fault according to the guidance provided by the voice system, the user can provide feedback to indicate that the problem has been solved, and the system will perform another test to confirm whether the fault has been truly resolved. If the problem feedback result indicates that the fault has been resolved, for example, the user has removed the obstruction, improved the ventilation conditions, or adjusted the usage time, the monitoring system will no longer detect the abnormal state. At this time, the voice broadcast system will confirm to the user again that the fault has been resolved and prompt the device to restart safely. The user can restart the oil heater through voice commands or other control methods, and the system will automatically enter normal working state and continue to provide users with a warm and comfortable environment. However, if the monitoring system still detects the same fault code after the user tries to solve the problem, it means that the fault has not been solved. In this case, the voice broadcast system will continue to output a second alarm signal, which usually refers to a more direct and urgent warning different from the initial alarm to remind the user that the fault still exists and requires further inspection or professional repair.

[0036] In some optional embodiments, the method further includes the following steps: step S204: when the dangerous goods exist in the preset area and the second alarm signal is not output, re-detecting the presence of the dangerous goods in the preset area; step S205: when the second alarm signal is not output again, determining that the safety detection function of the target heater has failed, and controlling the target heater to be powered off.

[0037] In the specific implementation process, the above content further refines the control logic of the electric oil heater in terms of safety detection and fault handling, ensuring that the device can continue to provide a safe and intelligent heating experience in a complex and changeable use environment. In the case that there are dangerous items in the preset area but no timely alarm is given, when the electric oil heater is running, its built-in safety monitoring module will continue to scan the preset area (usually within a certain range around the oil heater) to detect whether there are dangerous items that may cause fire, such as flammable materials, obstacles, etc. If dangerous items are detected in the preset area, the system will output the first alarm signal and remind the user to remove the dangerous items through voice broadcast to ensure safety. However, if the system detects the presence of dangerous items but does not output the second alarm signal (i.e., a more urgent warning signal) as expected, this may indicate that the safety detection function of the device has failed or failed. In this case, the system will perform the following steps: Detect whether there are dangerous items in the preset area again: The system will start a secondary detection process to confirm whether the dangerous items are still there. This step is designed to eliminate false alarms or short-term interference factors and ensure the accuracy of the alarm mechanism. Determine the failure of the safety detection function and control the power off: If the secondary detection still shows that there are dangerous items in the preset area, but the system still does not output the second alarm signal, it will be regarded as a failure of the safety detection function. To prevent potential safety risks, the system will automatically control the target heater to power off and stop the heating operation until the user or professional checks and solves the fault and ensures that the equipment is safe before restarting. It provides users with a more intelligent, convenient and safe use experience, and also reduces the cost of after-sales service for manufacturers.

[0038] In some optional embodiments, the above-mentioned step S203 of obtaining the fault code can be implemented by the following steps: Step S2031: Detect the current temperature of the target heater, and when the current temperature is greater than a preset temperature threshold, determine it as a first fault code; Step S2032: Detect the current current of the target heater, and when the current current is greater than a preset current threshold, determine it as a second fault code.

[0039] Specifically, the intelligent safety system of the electric oil heater monitors the operating status of the equipment in real time through integrated temperature sensors and current sensors. The system continuously monitors the current temperature of the target heater. If the detected temperature exceeds the preset temperature threshold (for example, a safe maximum operating temperature), the safety monitoring module will generate a first fault code. This indicates that the oil heater may be overheated, there is a risk of fire or other potential problems caused by high temperature. At the same time, the system monitors the current current of the target heater. If the current value exceeds the preset current threshold, this usually means that there is a circuit overload, short circuit or other current-related fault, and the safety monitoring module will generate a second fault code.

[0040] During the specific implementation process, the target heater includes a speaker and an indicator light, and outputs a first alarm signal and a second alarm signal, including: outputting a first voice signal corresponding to the first alarm signal and a second voice signal corresponding to the second alarm signal through the speaker; outputting a first light signal corresponding to the first alarm signal and a second light signal corresponding to the second alarm signal through the indicator light.

[0041] Specifically, the safety alarm mechanism of the electric oil heater outputs alarm signals through an integrated speaker and indicator light. Output voice signals through the speaker: When the system detects dangerous objects in a preset area or a fault inside the device, the speaker will output a voice warning. The first alarm signal corresponds to the first voice signal played when the safety problem is first detected, and the second alarm signal corresponds to the more urgent second voice signal played when the problem is not solved or the safety detection function fails. This sound prompt is particularly useful at night or when the user is away from the device, and can remind the user to pay attention to safety in time. Output light signals through indicator lights: In addition to voice warnings, the electric oil heater also outputs the first and second alarm signals through different colors and flashing modes of the indicator lights. For example, the first light signal may be a yellow steady light, indicating that there is a general safety problem, while the second light signal may be a red flashing light, indicating that the problem is serious or requires immediate action. The light signal provides a visual safety warning when the user is in a noisy environment or has hearing impairments. The temperature sensor inside the electric oil heater continuously monitors the current temperature of the device. If the detected temperature exceeds the preset temperature threshold (such as the maximum temperature for safe operation), the system will generate a first fault code, which indicates that the device may have a safety hazard due to overheating. The current sensor is used to monitor the current of the target heater. If the detected current value exceeds the preset current threshold (usually indicating a circuit overload, short circuit or other current abnormality), the system will generate a secondary fault code indicating a current-related fault.

[0042] In some optional embodiments, the above-mentioned step S201 obtains the usage time of the target heater, including the following steps: Step S2011: Obtain multiple historical usage times of the target heater, wherein the historical usage time represents the duration of each use of the target heater from the initial operation stage to the current operation stage; Step S2012: Calculate the sum of the multiple historical usage times to obtain the usage time.

[0043] Specifically, the system records the usage time of the target heater from the first operation to the current operation stage. Each time the device is started and shut down, its internal clock module and storage unit automatically record and save this information to ensure the accuracy and completeness of the data. During the life cycle of the device, the system calculates the sum of all historical usage times, that is, the usage time. This information is crucial to determine whether the device has reached the recommended service life or whether regular maintenance and inspection are required.

[0044] In the specific implementation process, outputting the first alarm signal and outputting the second alarm signal also includes the following steps: when the target heater is powered off, outputting a first offline signal corresponding to the first alarm signal and outputting a second offline signal corresponding to the second alarm signal, wherein the first offline signal is a pre-stored signal representing the first alarm signal, and the second offline signal is a pre-selected stored signal representing the second alarm signal.

[0045] Specifically, when the oil heater has a serious fault or the safety detection function fails, the system will control the device to be powered off to avoid possible safety risks. In the power-off state, the oil heater can still provide safety warnings through the pre-stored first offline signal and the second offline signal. These offline signals are pre-stored when the device is in normal operation, ensuring that in the case of power failure, the user can still receive urgent safety information through the speaker and indicator light. The first offline signal corresponds to the first alarm signal, which is usually related to excessive temperature or the presence of dangerous goods in the preset area, while the second offline signal corresponds to the more urgent second alarm signal, which may involve current abnormalities, equipment overheating, etc. or the complete failure of the safety detection function. When the device is powered off, through the short-term power supply of the built-in battery or capacitor, the oil heater can play the pre-stored voice warning through the speaker and issue a preset light warning through the indicator light to remind the user that there is a serious problem with the device and that immediate action is needed, such as contacting a professional maintenance service. The offline voice will store part of the voltage through the corresponding capacitor, and will continue to broadcast when the whole machine is powered off. It will stop after three broadcasts. After powering on, the whole machine will have a power-off memory and will execute the command before the power-off.

[0046] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the security warning method of the present application will be described in detail below in combination with specific embodiments.

[0047] This embodiment relates to a specific safety warning method, such as Figure 2 As shown, the following steps are included:

[0048] Step S1: power on;

[0049] Step S2: time recording;

[0050] Step S3: Determine whether the usage time has been exceeded, and if so, determine whether to issue an alarm, and if not, issue a voice prompt;

[0051] Step S4: the whole machine is running;

[0052] Step S5: Determine whether a fault occurs, if yes, determine whether to issue an alarm, if no, shut down;

[0053] Step S6: Determine whether an alarm is issued, and if so, determine whether the alarm is cleared, and if so, shut down the device;

[0054] Step S7: If no alarm is given, a secondary detection is performed, that is, the above step S6 is repeated.

[0055] The embodiments of the present application also provide a safety warning device. It should be noted that the safety warning device of the embodiments of the present application can be used to execute the safety warning method provided by the embodiments of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0056] The following is an introduction to the safety warning device provided in the embodiments of the present application.

The length of use each time can be obtained and stored in the corresponding memory chip. The corresponding memory chip will accumulate and superimpose to obtain the usage time, and determine whether it exceeds the corresponding time limit (preset time threshold). If it exceeds the corresponding time limit, the corresponding program will execute the alarm instruction to output the first alarm signal.

[0060] A detection unit 20, configured to detect whether there is a dangerous object in a preset area when the usage time is less than the preset time threshold, wherein the dangerous object is an object that affects the safety of the target heater, and the preset area is an area including the target heater;

[0061] Specifically, when the usage time is less than the preset time threshold, it indicates that the usage time meets the requirement, and the user needs to be reminded whether there are other flammable, explosive and other dangerous items in the preset area next to the whole machine to ensure the safety of the surrounding area of ​​the whole machine. During use, if the user has needs (such as placing wet quilts and clothes on the surface for drying), it is easy to cause a fault alarm; if there is no alarm response, the whole machine will be used normally until the whole machine is shut down and the operation ends.

[0062] The second output unit 30 is used to obtain a fault code and output a maintenance voice signal corresponding to the fault code when the dangerous goods exist in the preset area and a second alarm signal is output, wherein the second alarm signal is used to at least warn that the dangerous goods exist in the preset area, the fault code is a code that characterizes the fault type of the target heater, and the maintenance voice signal indicates maintenance suggestions for the fault type.

Therefore, the safety of the electric heater can be improved.

[0065] During the specific implementation process, the second output unit includes an acquisition module, a first control module and an output module. The acquisition module is used to obtain the problem feedback result corresponding to the fault code, wherein the problem feedback result is a result indicating whether the fault has been resolved; the first control module is used to control the target heater to enter a normal working state when the problem feedback result indicates that the fault has been resolved; the output module is used to continue to output the second alarm signal when the problem feedback result indicates that the fault has not been resolved. The device continues to control the heater through the problem feedback result, so that the target heater can be controlled according to real-time feedback, thereby improving the safety of the heater. In a specific implementation, the above steps are intended to promptly and accurately convey the fault status to the user through an offline voice broadcast system, and guide the user to troubleshoot and resolve the fault, thereby improving the safety performance and user experience of the equipment.

[0066] Specifically, when the monitoring system of the oil heater detects an abnormality in the device, such as overheating or short circuit, a corresponding fault code will be generated. These fault codes are identifiers of internal errors in the device, and each code corresponds to a different problem. At this stage, the voice control system will read the fault code and obtain the problem feedback result corresponding to the code from the preset fault database. The problem feedback result contains a specific description of the fault and guidance information on how to troubleshoot and solve it. For example, if the fault code indicates overheating, the voice broadcast system will inform the user of the possible cause of the overheating of the device and suggest that the user check whether there are any obstructions around the device, whether it is placed in a poorly ventilated environment, and whether the recommended usage time has been exceeded. Once the user solves the fault according to the guidance provided by the voice system, the user can provide feedback to indicate that the problem has been solved, and the system will perform another test to confirm whether the fault has been truly resolved. If the problem feedback result indicates that the fault has been resolved, for example, the user has removed the obstruction, improved the ventilation conditions, or adjusted the usage time, the monitoring system will no longer detect the abnormal state. At this time, the voice broadcast system will confirm to the user again that the fault has been resolved and prompt the device to restart safely. The user can restart the oil heater through voice commands or other control methods, and the system will automatically enter normal working state and continue to provide users with a warm and comfortable environment. However, if the monitoring system still detects the same fault code after the user tries to solve the problem, it means that the fault has not been solved. In this case, the voice broadcast system will continue to output a second alarm signal, which usually refers to a more direct and urgent warning different from the initial alarm to remind the user that the fault still exists and requires further inspection or professional repair.

[0067] In some optional embodiments, the device further includes a detection module and a second control module, the detection module being used to re-detect the presence of the dangerous goods in the preset area when the dangerous goods are present in the preset area and the second alarm signal is not output; the second control module being used to determine that the safety detection function of the target heater has failed and control the target heater to cut off power when the second alarm signal is not output again.

[0068] In the specific implementation process, the above content further refines the control logic of the electric oil heater in terms of safety detection and fault handling, ensuring that the device can continue to provide a safe and intelligent heating experience in a complex and changeable use environment. In the case that there are dangerous items in the preset area but no timely alarm is given, when the electric oil heater is running, its built-in safety monitoring module will continue to scan the preset area (usually within a certain range around the oil heater) to detect whether there are dangerous items that may cause fire, such as flammable materials, obstacles, etc. If dangerous items are detected in the preset area, the system will output the first alarm signal and remind the user to remove the dangerous items through voice broadcast to ensure safety. However, if the system detects the presence of dangerous items but does not output the second alarm signal (i.e., a more urgent warning signal) as expected, this may indicate that the safety detection function of the device has failed or failed. In this case, the system will perform the following steps: Detect whether there are dangerous items in the preset area again: The system will start a secondary detection process to confirm whether the dangerous items are still there. This step is designed to eliminate false alarms or short-term interference factors and ensure the accuracy of the alarm mechanism. Determine the failure of the safety detection function and control the power off: If the secondary detection still shows that there are dangerous items in the preset area, but the system still does not output the second alarm signal, it will be regarded as a failure of the safety detection function. To prevent potential safety risks, the system will automatically control the target heater to power off and stop the heating operation until the user or professional checks and solves the fault and ensures that the equipment is safe before restarting. It provides users with a more intelligent, convenient and safe use experience, and also reduces the cost of after-sales service for manufacturers.

[0069] In some optional embodiments, the second output unit includes a first determination module and a second determination module. The first determination module is used to detect the current temperature of the target heater, and when the current temperature is greater than a preset temperature threshold, it is determined as a first fault code; the second determination module is used to detect the current current of the target heater, and when the current current is greater than a preset current threshold, it is determined as a second fault code.

[0070] Specifically, the intelligent safety system of the electric oil heater monitors the operating status of the equipment in real time through integrated temperature sensors and current sensors. The system continuously monitors the current temperature of the target heater. If the detected temperature exceeds the preset temperature threshold (for example, a safe maximum operating temperature), the safety monitoring module will generate a first fault code. This indicates that the oil heater may be overheated, there is a risk of fire or other potential problems caused by high temperature. At the same time, the system monitors the current current of the target heater. If the current value exceeds the preset current threshold, this usually means that there is a circuit overload, short circuit or other current-related fault, and the safety monitoring module will generate a second fault code.

[0071] During the specific implementation process, the target heater includes a speaker and an indicator light, and the first output unit includes a first output module and a second output module. The first output module is used to output a first voice signal corresponding to the first alarm signal and a second voice signal corresponding to the second alarm signal through the speaker; the second output module is used to output a first light signal corresponding to the first alarm signal and a second light signal corresponding to the second alarm signal through the indicator light.

[0072] Specifically, the safety alarm mechanism of the electric oil heater outputs alarm signals through an integrated speaker and indicator light. Output voice signals through the speaker: When the system detects dangerous objects in a preset area or a fault inside the device, the speaker will output a voice warning. The first alarm signal corresponds to the first voice signal played when the safety problem is first detected, and the second alarm signal corresponds to the more urgent second voice signal played when the problem is not solved or the safety detection function fails. This sound prompt is particularly useful at night or when the user is away from the device, and can remind the user to pay attention to safety in time. Output light signals through indicator lights: In addition to voice warnings, the electric oil heater also outputs the first and second alarm signals through different colors and flashing modes of the indicator lights. For example, the first light signal may be a yellow steady light, indicating that there is a general safety problem, while the second light signal may be a red flashing light, indicating that the problem is serious or requires immediate action. The light signal provides a visual safety warning when the user is in a noisy environment or has hearing impairments. The temperature sensor inside the electric oil heater continuously monitors the current temperature of the device. If the detected temperature exceeds the preset temperature threshold (such as the maximum temperature for safe operation), the system will generate a first fault code, which indicates that the device may have a safety hazard due to overheating. The current sensor is used to monitor the current of the target heater. If the detected current value exceeds the preset current threshold (usually indicating a circuit overload, short circuit or other current abnormality), the system will generate a secondary fault code indicating a current-related fault.

[0073] In some optional embodiments, the first output unit includes an acquisition module and a calculation module, the acquisition module is used to acquire multiple historical usage times of the target heater, wherein the historical usage time represents the duration of each use of the target heater from the initial operation stage to the current operation stage; the calculation module is used to calculate the sum of the multiple historical usage times to obtain the usage time.

[0074] Specifically, the system records the usage time of the target heater from the first operation to the current operation stage. Each time the device is started and shut down, its internal clock module and storage unit automatically record and save this information to ensure the accuracy and completeness of the data. During the life cycle of the device, the system calculates the sum of all historical usage times, that is, the usage time. This information is crucial to determine whether the device has reached the recommended service life or whether regular maintenance and inspection are required.

[0075] During the specific implementation process, the first output unit also includes a third output module, which is used to output a first offline signal corresponding to the first alarm signal and a second offline signal corresponding to the second alarm signal when the target heater is powered off, wherein the first offline signal is a pre-stored signal representing the first alarm signal, and the second offline signal is a pre-selected stored signal representing the second alarm signal.

[0076] Specifically, when the oil heater has a serious fault or the safety detection function fails, the system will control the device to be powered off to avoid possible safety risks. In the power-off state, the oil heater can still provide safety warnings through the pre-stored first offline signal and the second offline signal. These offline signals are pre-stored when the device is in normal operation, ensuring that in the case of power failure, the user can still receive urgent safety information through the speaker and indicator light. The first offline signal corresponds to the first alarm signal, which is usually related to excessive temperature or the presence of dangerous goods in the preset area, while the second offline signal corresponds to the more urgent second alarm signal, which may involve current abnormalities, equipment overheating, etc. or the complete failure of the safety detection function. When the device is powered off, through the short-term power supply of the built-in battery or capacitor, the oil heater can play the pre-stored voice warning through the speaker and issue a preset light warning through the indicator light to remind the user that there is a serious problem with the device and that immediate action is needed, such as contacting a professional maintenance service. The offline voice will store part of the voltage through the corresponding capacitor, and will continue to broadcast when the whole machine is powered off. It will stop after three broadcasts. After powering on, the whole machine will have a power-off memory and will execute the command before the power-off.

[0077] The safety warning device includes a processor and a memory, and the first output unit, the detection unit, the second output unit, etc. are all stored in the memory as program units, and the processor executes the program units stored in the memory to implement corresponding functions. The above modules are all located in the same processor; or, the above modules are located in different processors in any combination.

[0078] The processor includes a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be set, and the problem of not being able to find and troubleshoot the fault in time when the electric heater product fails can be solved by adjusting the kernel parameters.

[0079] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0081] Specifically, the safety warning methods include:

[0082] Step S201, obtaining the usage time of the target heater, and outputting a first alarm signal when the usage time is greater than or equal to a preset time threshold, wherein the first alarm signal is used to warn that the target heater has reached a maximum usage time;

[0083] Specifically, the target heater in this embodiment is explained by taking the electric oil heater as an example. The existing electric oil heater already has an offline function, but it is often a simple entry and a fool-proof voice operation method. However, in actual use, users often report that when a fault occurs, they need to check the instructions or use the browser to search for related questions and answers, and the user experience is not good. In view of this, a voice safety broadcast logic is set to enhance human-computer interaction and troubleshooting purposes, thereby enhancing the user experience. First, when the user uses the whole machine, by turning on the machine, the chip will record the power-on time each time, and the power-off time will be recorded at the end. The length of use each time can be obtained and stored in the corresponding memory chip. The corresponding memory chip will accumulate and superimpose to obtain the usage time, and determine whether it exceeds the corresponding time limit (preset time threshold). If it exceeds the corresponding time limit, the corresponding program will execute the alarm instruction to output the first alarm signal.

[0084] Step S202, when the usage time is less than the preset time threshold, detecting whether there is a dangerous object in a preset area, wherein the dangerous object is an object that affects the safety of the target heater, and the preset area is an area including the target heater;

[0085] Specifically, when the usage time is less than the preset time threshold, it indicates that the usage time meets the requirement, and the user needs to be reminded whether there are other flammable, explosive and other dangerous items in the preset area next to the whole machine to ensure the safety of the surrounding area of ​​the whole machine. During use, if the user has needs (such as placing wet quilts and clothes on the surface for drying), it is easy to cause a fault alarm; if there is no alarm response, the whole machine will be used normally until the whole machine is shut down and the operation ends.

[0086] Step S203, when the dangerous goods exist in the preset area and a second alarm signal is output, a fault code is obtained, and a maintenance voice signal corresponding to the fault code is output, wherein the second alarm signal is used to at least warn that the dangerous goods exist in the preset area, the fault code is a code that characterizes the fault type of the target heater, and the maintenance voice signal indicates maintenance suggestions for the fault type.
