Description

Technical Field

[0001] This invention relates to the field of intelligent control, and in particular to a method, device, system, electronic device and storage medium for the linkage control of lighting and heat preservation power. Background Technology

[0002] Food warming devices are kitchen appliances used to continuously keep dishes, plates, or food containers warm. They typically include a heating module, temperature detection components, power supply components, and status indicator components. In catering, home dining, or commercial food preparation scenarios, food warming devices need to maintain appropriate heat preservation effects under different power levels, plate temperatures, and load conditions. They also need to indicate to the user whether the device is currently in heating, heat preservation, standby, or malfunction mode.

[0003] Existing food warming equipment mostly uses temperature threshold control to start and stop heating, or uses fixed power levels for heat preservation, with lighting components typically serving only as independent status indicators. Because there is no stable linkage between heat preservation power control and lighting status, when the equipment is in states such as low battery, no-load, reduced heat preservation power, or stopped output, users cannot accurately determine the actual output status of the heating module through the lights. This can easily lead to misinterpretations such as the equipment still maintaining normal heat preservation, accidental triggering of high-power operation, or failure to detect heat preservation abnormalities in a timely manner, affecting the equipment's safety, energy efficiency, and user experience.

[0004] Therefore, there is an urgent need to provide a lighting and heat preservation power linkage control scheme for food warming equipment to solve the problems of insufficient correspondence between heat preservation output status and lighting indication status, unintuitive identification of equipment operation status, poor energy consumption control under low power or no-load conditions, and easy misjudgment of heat preservation status by users in existing food warming equipment.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, Figure 1 This is a flowchart of a lighting and heat preservation power linkage control method provided by an embodiment of the present invention. The lighting and heat preservation power linkage control method includes the following steps: 101. Obtain the operating status data of the food warming equipment.

[0021] In this embodiment of the invention, the above-mentioned lighting and heat preservation power linkage control method can be applied to a lighting and heat preservation power linkage control platform. The lighting and heat preservation power linkage control platform has functions such as lighting and heat preservation power linkage control data processing, lighting and heat preservation power linkage control data transmission and reception, and lighting and heat preservation power linkage control data memory storage. It can be built based on a server or server cluster. The server or server cluster can be an electronic device with lighting and heat preservation power linkage control data processing capability.

[0022] The aforementioned food warming equipment refers to kitchen equipment used to heat and keep warm plates, dishes, or food containers. It includes components such as a heating module, lighting components, a temperature sampling module, a power detection module, and a controller. For example, the equipment can use an NTC temperature sampling module to collect the temperature of the hot plate or dish, use a power detection module to obtain the remaining battery power, and use the heating module to output heat to keep the food warm. The lighting components can be indicator lights, light strips, or other luminous components that can output status indicators to show the status of the heating module's heat preservation output.

[0023] The aforementioned operational status data is a set of data used to characterize the current working status of the food warming equipment. It can include battery status data, temperature status data, and load status data. The battery status data can reflect the remaining battery power, battery range, or battery power change trend; the temperature status data can be derived from NTC temperature sampling data, converted temperature of the hot food plate, or temperature change trend; the load status data can indicate whether there are plates, dishes, or other heat-absorbing loads on the food warming equipment, or it can indicate whether it is currently in an unloaded, loaded, or standby state after the plates have been removed.

[0024] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can receive power detection data uploaded by the power detection module to obtain power status data; receive temperature sampling data uploaded by the temperature sampling module to obtain temperature status data; and determine load status data based on the temperature status data within a preset detection range during the heating or cooling process.

[0025] For example, when the hot cutting board heats up slowly during the heating process and there is a significant temperature drop after heating stops, it indicates that the plate or dish is continuously absorbing heat, and the aforementioned light and heat preservation power linkage control platform can determine that there is a load at present; when the hot cutting board heats up quickly and does not show stable heat absorption characteristics, it can be determined that the current state is no load or standby.

[0026] The above method enables the generation of operating status data using power, temperature, and load-related data without adding additional load identification hardware. This provides a consistent data source for subsequent heat preservation power control and light indication control, reducing ineffective heat output under no-load or low-power conditions.

[0027] 102. Based on the operational status data, determine the target linkage scenario corresponding to the food warming equipment.

[0028] In this embodiment of the invention, the aforementioned target linkage scenario can refer to a control scenario jointly determined by the current power status, temperature status, and load status of the food warming device, which is used to uniformly constrain subsequent heat preservation power control and light prompt control.

[0029] It is understandable that the aforementioned target linkage scenarios are not simply temperature control states or light display states, but rather a combined judgment result obtained by considering factors such as whether the battery is sufficient, whether the hot cutting board temperature is within the keep-warm range, and whether the food warming device is loaded with plates or dishes. For example, the aforementioned target linkage scenarios may include idle standby scenarios, low battery keep-warm limitation scenarios, heating and keep-warm scenarios, constant temperature maintenance scenarios, and overheating power reduction scenarios.

[0030] In one possible embodiment, the above-mentioned lighting and heat preservation power linkage control platform can determine the power operating range based on power status data, the temperature operating range based on temperature status data, and the load operating state based on load status data; then, the power operating range, the temperature operating range, and the load operating state are combined to obtain the current operating state range.

[0031] The aforementioned lighting and insulation power linkage control platform can also match the current operating state range with preset operating state scenarios to determine the target linkage scenario. For example, when the load is in an idle state or a panel removal state, the platform can determine the target linkage scenario as an idle standby scenario; when the load is in a load state and the power consumption range is in a low power consumption range, the platform can determine the target linkage scenario as a low power consumption insulation limitation scenario; when the load is in a load state, the power consumption range is in a normal power supply range, and the temperature range is below the insulation requirement range, the platform can determine the target linkage scenario as a heating and insulation scenario; when the temperature range is within the insulation requirement range, the platform can determine the scenario as a constant temperature maintenance scenario; and when the temperature range is above the preset power reduction range, the platform can determine the scenario as an overheating power reduction scenario.

[0032] By using the above methods and steps, the three states of power, temperature and load can be converted into executable linkage scenarios, so that subsequent heat preservation output control and light prompt control are generated based on the same scenario results, reducing state conflicts between different control logics.

[0033] 103. Generate corresponding target control strategies based on target linkage scenarios.

[0034] In this embodiment of the invention, the aforementioned target control strategy can refer to a set of control rules obtained from the target linkage scene transformation, used to simultaneously constrain the heat preservation output of the heating module and the prompt output of the lighting component. The aforementioned target control strategy may include a target heat preservation power control strategy and a target lighting control strategy.

[0035] Specifically, the aforementioned target heat preservation power control strategy is used to determine whether the heating module should increase power output, maintain power output, decrease power output, or stop output under the current target linkage scenario; the aforementioned target lighting control strategy is used to determine whether the lighting component should output heat preservation prompts, standby prompts, low battery prompts, or fault prompts under the current target linkage scenario. It is understood that the aforementioned target heat preservation power control strategy and the aforementioned target lighting control strategy are not generated independently, but rather form a corresponding relationship based on the same target linkage scenario.

[0036] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can determine the current heat output demand and lighting indication demand of the food warming equipment based on the target linkage scenario, and determine the current available output power range and energy-saving constraints of the food warming equipment in combination with power status data.

[0037] Specifically, the candidate thermal output power of the heating module can be determined based on the thermal output requirements, and the candidate lighting output parameters of the lighting components can be determined based on the lighting prompt requirements. Then, based on the available output power range and energy-saving constraints, the candidate thermal output power and candidate lighting output parameters are processed for power balancing to obtain the target thermal output power and target lighting output parameters.

[0038] For example, in a heating and heat preservation scenario, the target control strategy can prioritize ensuring the heat output power of the heating module and control the lighting component to output a heat preservation warning status; in a low battery heat preservation limitation scenario, the target control strategy can limit the heat output power of the heating module and control the lighting component to output a low battery warning status; in an idle standby scenario, the target control strategy can control the heating module to stop outputting heat and control the lighting component to output a standby warning status.

[0039] By using the above methods and steps, the heat preservation output of the heating module and the prompt output of the lighting component can be generated under the same target control strategy, reducing the problem of inconsistency between the light prompt and the actual heat preservation output state, and reducing the ineffective heat output under low power or no-load conditions.

[0040] 104. Based on the target heat preservation power control strategy, determine the target heat output power corresponding to the heating module, and control the heating module to perform heat preservation output control according to the target heat output power.

[0041] In this embodiment of the invention, the aforementioned target thermal output power refers to the actual thermal insulation and heating power that the heating module needs to output under the current target thermal insulation power control strategy. It is understood that the aforementioned target thermal output power is not a fixed power value, but is jointly determined by the current target linkage scenario, power status, temperature status, load status, and model power parameters of the aforementioned food warming equipment.

[0042] For example, under load, if the temperature of the hot dish is lower than the preset heat preservation range, the target heat output power can correspond to the higher heat preservation power allowed by the current power range; if the temperature of the hot dish is within the preset heat preservation range, the target heat output power can correspond to the heat preservation power maintained; if the temperature of the hot dish is higher than the preset power reduction range, the target heat output power can correspond to the reduced heat preservation power; if the food warming device is in no-load, low power protection, or abnormal protection state, the target heat output power can correspond to low power, safe power, or stop output power.

[0043] In one possible embodiment, the above-mentioned lighting and heat preservation power linkage control platform can determine the heat preservation output mode according to the target heat preservation power control strategy. The heat preservation output mode may include a heating output mode, a constant temperature maintenance mode, a power reduction output mode, and a stop output mode.

[0044] The aforementioned lighting and heat preservation power linkage control platform can also determine the higher power allowed by the current power range as the target thermal output power in the heating output mode; determine the maintenance power that matches the current temperature state as the target thermal output power in the constant temperature maintenance mode; determine the limit power that is lower than the current thermal output power as the target thermal output power in the power reduction output mode; and determine the target thermal output power as zero power or the power to stop heating in the stop output mode.

[0045] The aforementioned lighting and heat preservation power linkage control platform can also adjust the target heat output power based on the power parameters of the food warming equipment model, ensuring that different specifications of food warming equipment output heat preservation power that matches their own heating capacity under the same target linkage scenario. After determining the target heat output power, the platform can generate a heating drive control signal and send it to the heating module, causing the module to heat, maintain, reduce power, or stop heating according to the target heat output power.

[0046] Through the above method, this embodiment can match the actual heat output of the heating module with the power, temperature and load status, reducing overheating, insufficient temperature rise or low power invalid output caused by fixed power output.

[0047] 105. Based on the target lighting control strategy, control the lighting component output and the lighting indication status corresponding to the current heat preservation output control status of the heating module.

[0048] In this embodiment of the invention, the aforementioned light prompt status may refer to the visual prompt result output by the light component based on the current operating status of the device, which is used to reflect the working mode of the heating module or the linkage scenario in which the device is located.

[0049] For example, the aforementioned light indicator states may include a heat preservation indicator state, a standby indicator state, a low battery indicator state, and a fault indicator state, etc. The different light indicator states can be distinguished by the on / off state of the light, the brightness level, or the flashing rhythm.

[0050] The aforementioned heat preservation output control state refers to the operating state of the heating module under the action of the target heat output power, and is used to characterize the actual working mode of the current heating module.

[0051] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can obtain the current heat preservation output control status of the heating module. For example, it can determine the output status of the heating module by detecting whether the current target heat output power is in the heating power range, the maintenance power range, the power reduction range, or the zero power range. The aforementioned lighting and heat preservation power linkage control platform can call the corresponding lighting prompt parameters in the target lighting control strategy according to the current heat preservation output control status. When the heating module is in the heating output state, it controls the lighting component to output a heat preservation prompt status; when the heating module is in the constant temperature maintenance state, it controls the lighting component to output a stable heat preservation prompt status; when the heating module is in the power reduction output state, it controls the lighting component to output a power limited prompt status; and when the heating module is in the stopped output state, it controls the lighting component to output a standby or low battery prompt status.

[0052] By using the above methods, the indicator light status is kept consistent with the actual heat preservation output control status of the heating module, thereby improving the recognizability of the equipment's operating status and reducing the probability of users misjudging the heat preservation status.

[0053] In this embodiment of the invention, the operating status data of the food warming equipment is acquired; based on the operating status data, the target linkage scenario corresponding to the food warming equipment is determined; based on the target linkage scenario, a corresponding target control strategy is generated; based on the target heat preservation power control strategy, the target heat output power corresponding to the heating module is determined, and the heating module is controlled to perform heat preservation output control according to the target heat output power; based on the target lighting control strategy, the lighting component outputs a lighting indication state corresponding to the current heat preservation output control state of the heating module. Through the above method steps, the lighting indication state can be synchronized with the heat preservation output control state, reducing ineffective heat output under no-load, low-power, or power-limited states, and improving the power distribution accuracy, heat preservation stability, and energy consumption control reliability of the food warming equipment.

[0054] Optionally, in the step of acquiring the operating status data of the food warming device, the following steps can also be taken: acquiring battery power detection data within a preset detection period, and determining power status data based on the changing trend of the power detection data; acquiring temperature sampling data of the hot food board within a preset detection period, and determining temperature status data based on the changing trend of the temperature sampling data; determining load status data based on the heating and cooling process characteristics of the temperature sampling data within a preset temperature range; and generating operating status data based on the power status data, temperature status data, and load status data.

[0055] In this embodiment of the invention, the aforementioned preset detection period refers to the dynamic time window used by the aforementioned lighting and heat preservation power linkage control platform to collect and analyze the power and temperature status. It should be noted that the aforementioned preset detection period is not a fixed period, but is adjusted according to the operating status of the food warming equipment. For example, when the power is stable and the temperature changes slowly, a longer detection period can be used to reduce computation and lighting power consumption; when the power drops rapidly, the temperature of the hot food plate changes rapidly, or when a plate is being placed or removed, the detection period can be shortened so that the aforementioned lighting and heat preservation power linkage control platform can more quickly identify load changes and simultaneously adjust the heat output power and lighting indication status.

[0056] The aforementioned battery power detection data refers to battery power-related data collected by the power detection module, including remaining power, battery voltage, discharge current, or power range indicators. This battery power detection data is not only used to determine whether the battery is low, but also to determine the power boundaries for subsequent heat output and lighting output. For example, when the battery level is within the normal range, the heating module can be allowed to perform higher heat output power; when the battery level drops to the protection range, the aforementioned lighting and heat preservation power linkage control platform can limit the heating module's power increase and cause the lighting components to output a low battery or power-limited warning.

[0057] In this embodiment, the aforementioned lighting and heat preservation power linkage control platform can determine the trend of change based on the direction, magnitude, and speed of change among multiple continuous sampled values. For example, when the power consumption continuously decreases and the decrease exceeds a preset range, it can be determined as a power consumption attenuation trend; when the temperature continuously rises, it can be determined as a heating trend; when the temperature continues to decrease after heating stops, it can be determined as a temperature drop trend. These trends can serve as the basis for linkage control, enabling the heat output power and lighting indication status to respond not only to the current instantaneous value but also to the process of equipment status changes.

[0058] The aforementioned temperature sampling data can refer to the temperature data collected by the temperature sampling module near the hot cutting board, heating film, or along the heat transfer path. This temperature sampling data can be NTC temperature sampling data, or it can be temperature-compensated data representing the actual temperature of the hot cutting board or plate. The aforementioned lighting and heat preservation power linkage control platform can identify whether heat is absorbed by the load based on the temperature sampling data, and thereby determine whether the heating module should increase power, maintain power, decrease power, or stop output.

[0059] The aforementioned heating process characteristics refer to the process characteristics formed when the temperature sampling data rises within a preset temperature range after the heating module outputs heat. These characteristics include the duration of heating, the rate of heating, the magnitude of heating, or the number of heating cycles required to reach the target temperature. For example, under no-load conditions, heat is not easily absorbed by the plates or dishes, and the hot plate heats up quickly; under load conditions, the plates or dishes continuously absorb heat, and the hot plate heats up more slowly. The aforementioned lighting and heat preservation power linkage control platform can use this difference to determine whether there is an effective load.

[0060] The aforementioned cooling process characteristics refer to the process characteristics formed when the temperature sampling data decreases after the heating module stops outputting or reduces output. These characteristics include the magnitude of the temperature drop, the rate of temperature drop, the duration of the temperature drop, or the time required for the temperature to return to the preset temperature. If the temperature continues to drop significantly and continuously after heating stops, it usually indicates that the plate or food is still absorbing heat. If the temperature drop is small or quickly reaches a stable state, it can be used as a basis for no-load judgment. Using the aforementioned cooling process characteristics in conjunction with the heating process characteristics can reduce load misjudgments caused by relying solely on the duration of a single heating cycle.

[0061] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can acquire battery power detection data within a preset detection period and determine the power status data based on the changing trend of the power detection data; it can also acquire temperature sampling data of the hot cutting board within a preset detection period and determine the temperature status data based on the changing trend of the temperature sampling data.

[0062] Specifically, the aforementioned lighting and heat preservation power linkage control platform can record the duration and rate of heating after the hot cutting board enters the preset temperature range, and record the temperature drop magnitude and rate of temperature drop after the heating module stops outputting or reduces power output.

[0063] When the temperature rises rapidly and the cooling process does not show continuous heat absorption characteristics, the aforementioned lighting and heat preservation power linkage control platform can determine that the load status data is in an unloaded state; when the temperature rises slowly or a significant temperature drop occurs after heating stops, the aforementioned lighting and heat preservation power linkage control platform can determine that the load status data is in a loaded state; when the original load status disappears and the equipment remains powered on, the aforementioned lighting and heat preservation power linkage control platform can determine that the load status data is in a tray removal standby state.

[0064] In this way, the operating status data can be generated by using changes in electricity, the heating process, and the cooling process together, so that the subsequent heat output power and light indication status can be linked and controlled based on the same detection result.

[0065] Optionally, the step of determining the target linkage scenario corresponding to the food warming device based on the operating status data further includes determining the power operating range corresponding to the food warming device based on power status data; determining the temperature operating range corresponding to the food warming device based on temperature status data; determining the load operating state corresponding to the food warming device based on load status data; determining the operating state range corresponding to the food warming device based on the power operating range, temperature operating range, and load operating state; and matching the operating state range with preset operating state scenarios to determine the target linkage scenario corresponding to the food warming device.

[0066] In this embodiment of the invention, the aforementioned power operating range can refer to a power supply constraint range mapped from power status data. It should be noted that the aforementioned power operating range not only indicates the remaining battery power but can also be determined by considering the power decline trend to determine whether the heating module is allowed to enter a higher thermal output power range. For example, when the power is in the normal range, the heating module can be allowed to increase its power output according to temperature requirements; when the power enters the protection range, even if the temperature is low, the target thermal output power of the heating module can be limited, and the lighting component can display a low battery warning or a power-limited warning.

[0067] The aforementioned temperature operating range refers to the heat adjustment range determined by temperature status data, indicating whether the hot cutting board currently needs additional heating, heat preservation, or power reduction. This temperature operating range can be determined based on the actual temperature of the hot cutting board, temperature change trends, and heat transfer compensation results.

[0068] For example, when the temperature is below the insulation requirement, it corresponds to the supplementary heating range; when the temperature is within the insulation requirement range, it corresponds to the constant temperature range; when the temperature is above the power reduction threshold, it corresponds to the overheating limitation range. The above temperature operating ranges need to be used in conjunction with the power operating range to avoid triggering high power output simply based on low temperature results when the power is low.

[0069] The aforementioned load operating status refers to the load-bearing status of the hot food equipment determined by load status data, which may include, but is not limited to, no-load status, load status, and tray-removal standby status. It can generally be determined based on the characteristics of the heating and cooling processes. For example, if the temperature rises rapidly and there is no significant temperature drop after heating stops, it can be determined as no-load status; if the temperature rises slowly or there is a continuous temperature drop after heating stops, it can be determined as load status; if the original load status disappears but the equipment remains powered on, it can be determined as tray-removal standby status. The aforementioned load operating status can have a priority constraint effect on heat output control. For example, even if the temperature is low in the no-load state, it will not directly trigger the heat preservation power output.

[0070] The aforementioned operating state range can refer to a comprehensive operating range formed by a combination of power operating range, temperature operating range, and load operating state. This operating state range indicates the current type of linkage control condition under which the food heating equipment is operating.

[0071] For example, "normal power range, supplementary heating range, and load status" can correspond to normal heating and heat preservation conditions; "low power range, supplementary heating range, and load status" can correspond to limited heat preservation conditions; and "any power range, any temperature range, and no-load status" can correspond to no-load standby conditions. By combining these methods, heating decisions can be avoided based solely on a single temperature or a single power level.

[0072] The aforementioned preset working state scenarios refer to the correspondence between pre-established working state intervals and linked scenarios. These preset working state scenarios may include heating and heat preservation scenarios, constant temperature maintenance scenarios, overheating power reduction scenarios, low battery heat preservation limitation scenarios, and idle standby scenarios. Each preset working state scenario can correspond to a set of heat preservation output requirements and light indication requirements. For example, the low battery heat preservation limitation scenario can correspond to limiting heat output power and outputting a low battery indication, while the idle standby scenario can correspond to stopping heating and outputting a standby indication.

[0073] In this embodiment, the currently determined working state range can be matched with preset working state scenarios. Specifically, priority matching can be used when multiple scenarios are met simultaneously. For example, when the temperature working range indicates that additional heating is needed, but the load working state is in an idle state, the idle standby scenario can be matched first; when the load working state is in a load state but the power working range enters the protection range, the low power insulation limitation scenario can be matched first, rather than directly matching the heating insulation scenario.

[0074] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can determine the power operating range corresponding to the food warming equipment based on power status data, determine the temperature operating range corresponding to the food warming equipment based on temperature status data, and determine the load operating state corresponding to the food warming equipment based on load status data.

[0075] The aforementioned lighting and heat preservation power linkage control platform can also combine the power working range, temperature working range and load working status to obtain the working status range corresponding to the food heating equipment, and then match the working status range with the preset working status scenario to determine the target linkage scenario.

[0076] For example, when the working status interval represents normal power, low temperature heat replenishment, and the presence of a load, the target linkage scenario can be determined as a heating and heat preservation scenario; when the working status interval represents low power, low temperature heat replenishment, and the presence of a load, the target linkage scenario can be determined as a low power heat preservation limitation scenario; when the working status interval represents no load or tray removal standby, the target linkage scenario can be determined as an no load standby scenario.

[0077] The above method can unify the power constraints, temperature requirements, and load identification results into a target linkage scenario, so that subsequent heat preservation power control and light prompt control have the same judgment basis.

[0078] Optionally, the step of generating a corresponding target control strategy based on the target linkage scenario further includes: determining the heat output requirements and lighting prompt requirements of the food warming equipment based on the target linkage scenario; determining the available output power range and energy-saving constraints of the food warming equipment based on power status data; determining the candidate heat output power of the heating module based on the heat output requirements; determining the candidate lighting output parameters of the lighting components based on the lighting prompt requirements; performing power balancing processing on the candidate heat output power and candidate lighting output parameters based on the available output power range and energy-saving constraints to obtain the target heat output power and target lighting output parameters; generating a target heat preservation power control strategy based on the target heat output power; and generating a target lighting control strategy based on the target lighting output parameters.

[0079] In this embodiment of the invention, the aforementioned heat output requirement refers to the heat output requirement proposed by the food warming device to the heating module under the target linkage scenario, used to characterize the current need for heating up, maintaining heat, reducing power, or stopping heating. It should be noted that the aforementioned heat output requirement can be directly determined by the target linkage scenario. For example, a heating and heat maintenance scenario corresponds to a higher heat output requirement, a constant temperature maintenance scenario corresponds to a stable heat output requirement, an idle standby scenario corresponds to a stop heat output requirement, and a low battery heat maintenance limitation scenario corresponds to a limited heat output requirement.

[0080] The aforementioned lighting indicator requirement refers to the output requirement of the lighting components by the food heating equipment in the target linkage scenario, to ensure that the lighting indicator state corresponds to the heat output state. This requirement can be linked through heat preservation output, power protection, and load status. For example, when the heating module is in a limited output state, the lighting indicator requirement can correspond to a power limitation indicator; when the heating module stops outputting but the equipment is not turned off, the lighting indicator requirement can correspond to a standby indicator; in a fault protection scenario, the lighting indicator requirement can correspond to a fault indicator.

[0081] The aforementioned available output power range refers to the total power range that the food heating device is allowed to allocate to the heating module and lighting components under the current battery level. This available output power range can be determined based on the remaining battery power, battery discharge capacity, battery operating range, and the model's power limit. For example, when the battery level is within the normal range, the available output power range allows the heating module to perform higher power output; when the battery level enters the protection range, the available output power range is narrowed to limit the heating module's power increase and reduce unnecessary power consumption by the lighting components.

[0082] The aforementioned energy-saving constraints refer to control conditions that constrain heating power and lighting power while meeting the requirements of heat preservation control and status indication. These constraints may include, but are not limited to, low battery limits, no-load heating stop conditions, low-power lighting indication conditions, and fault protection conditions. For example, in a low battery state, the lighting brightness can be reduced or the flashing interval extended; in a no-load state, the heating module output can be stopped, with only the low-power standby light remaining; and in a fault state, necessary fault indications can be retained while the heating module's power output is prohibited from increasing.

[0083] The aforementioned candidate thermal output power can refer to the output power of the heating module initially determined based on thermal output requirements. For example, in a heating and heat preservation scenario, the candidate thermal output power can correspond to the higher heating power allowed by the current power range; in a constant temperature maintenance scenario, the candidate thermal output power can correspond to the medium to low power required to maintain the temperature; and in an idle standby scenario, the candidate thermal output power can be the power at which output is stopped.

[0084] The aforementioned candidate light output parameters may refer to the output parameters of the light components initially determined based on the light indication requirements. For example, the heat preservation state may correspond to a constant light or low frequency indication, the low battery state may correspond to an intermittent flashing indication, and the fault state may correspond to an indication mode different from the normal heat preservation state.

[0085] In one possible embodiment, under the conditions of available output power range and energy-saving constraints, a coordinated correction process can be performed on the candidate thermal output power and candidate lighting output parameters to avoid the total power consumption exceeding the battery power supply capacity due to the independent output of the heating module and lighting components. For example, when the total power corresponding to the candidate thermal output power and candidate lighting output parameters exceeds the available output power range, the aforementioned lighting and heat preservation power linkage control platform can first reduce the lighting brightness or reduce the flicker duty cycle; if it still exceeds the power range, then the thermal output power of the heating module can be reduced. For no-load or fault scenarios, necessary lighting prompts can be retained first, while the heating module stops outputting.

[0086] The aforementioned target thermal output power refers to the actual operating power of the heating module determined after power balancing. This target thermal output power is matched with the current power status, temperature status, and load status, and is used to control the heating module to perform temperature increase, maintenance, power reduction, or stop output. Compared to candidate thermal output powers, the target thermal output power has been comprehensively adjusted for power protection, energy-saving constraints, and indicator light requirements.

[0087] The aforementioned target light output parameters refer to the actual output parameters of the lighting components determined after power balancing. These target light output parameters are used to control the light component output corresponding to the target thermal output power. For example, when the target thermal output power is reduced, the target light output parameters can be adjusted to a power-limited indicator; when the target thermal output power is at the stop output power, the target light output parameters can be adjusted to a standby indicator or a low battery indicator.

[0088] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can determine the heat output requirements and lighting indication requirements of the food warming equipment based on the target linkage scenario, and determine the available output power range and energy-saving constraints of the food warming equipment based on the power status data.

[0089] The aforementioned lighting and heat preservation power linkage control platform can determine the candidate heat output power corresponding to the heating module based on the heat output demand, determine the candidate light output parameters corresponding to the lighting component based on the light prompt demand, and then determine whether the total output power corresponding to the candidate heat output power and the candidate light output parameters is within the range of available output power.

[0090] If the total output power is within the available output power range, the candidate thermal output power and candidate lighting output parameters are determined as the target thermal output power and target lighting output parameters, respectively. If the total output power exceeds the available output power range, the candidate thermal output power and candidate lighting output parameters are corrected according to energy-saving constraints to obtain the target thermal output power and target lighting output parameters. The aforementioned lighting and insulation power linkage control platform can generate a target insulation power control strategy based on the target thermal output power and a target lighting control strategy based on the target lighting output parameters.

[0091] The above methods can coordinate heating output and light indication under the same power constraint, reducing ineffective power consumption in low power or no-load conditions.

[0092] Optionally, the step of performing power balancing processing on candidate thermal output power and candidate lighting output parameters based on the available output power range and energy-saving constraints to obtain target thermal output power and target lighting output parameters further includes determining candidate total output power based on candidate thermal output power and candidate lighting output parameters; if candidate total output power is within the available output power range, then candidate thermal output power is determined as target thermal output power, and candidate lighting output parameters are determined as target lighting output parameters; if candidate total output power exceeds the available output power range, then candidate thermal output power and / or candidate lighting output parameters are adjusted based on energy-saving constraints to obtain target thermal output power and target lighting output parameters.

[0093] In this embodiment of the invention, the aforementioned candidate total output power can refer to the expected output power formed by the candidate thermal output power and the lighting consumption power corresponding to the candidate lighting output parameters. The aforementioned candidate total output power is used to determine whether the current control scheme exceeds the output range that the food heating equipment can withstand under the current power condition.

[0094] For example, even if the heat output demand is high when the battery is low, if the combined heat output power of the candidate and the power required by the light indicator exceeds the range of available output power, the heating output or light output needs to be adjusted.

[0095] In one possible embodiment, the aforementioned lighting and insulation power linkage control platform can determine the candidate total output power based on candidate thermal output power and candidate lighting output parameters. The platform can also determine the candidate lighting power consumption of the lighting components based on the candidate lighting output parameters, and synthesize the candidate thermal output power and candidate lighting power consumption to obtain the candidate total output power.

[0096] If the candidate total output power is within the range of available output power, it means that the current power status can simultaneously support the heat output of the heating module and the prompt output of the lighting component. The above-mentioned lighting and heat preservation power linkage control platform can determine the candidate heat output power as the target heat output power and the candidate light output parameters as the target light output parameters.

[0097] If the total candidate output power exceeds the available output power range, the aforementioned lighting and insulation power linkage control platform can adjust the candidate thermal output power and / or candidate lighting output parameters based on energy-saving constraints. For example, when the load is being insulated and the battery level is close to the protection range, the lighting brightness can be reduced or the lighting flicker duty cycle can be decreased to prioritize the necessary thermal output; in no-load standby or low-battery protection scenarios, the candidate thermal output power can be reduced or the heating module can be controlled to stop outputting while retaining the low-power lighting indicator.

[0098] The above method can coordinate heat output and light indication under limited power conditions, avoiding excessive power consumption caused by independent output of heating module and light component.

[0099] Optionally, in the step of determining the target thermal output power corresponding to the heating module based on the target thermal power control strategy and controlling the heating module to perform thermal output control according to the target thermal output power, the method further includes determining the thermal output mode corresponding to the heating module based on the target thermal power control strategy. The thermal output mode includes at least one of the following: heating output mode, constant temperature maintenance mode, power reduction output mode, and stop output mode; generating a heating drive control signal based on the target thermal output power, and controlling the heating module to perform thermal output control based on the heating drive control signal.

[0100] In this embodiment of the invention, the aforementioned heat preservation output mode refers to the output operation mode of the heating module under the target heat preservation power control strategy, which can be determined according to the target linkage scenario, the target heat output power, and the current temperature state. For example, the heating output mode can be used for scenarios where the temperature of the hot plate is lower than the heat preservation requirement and the power supply allows for supplemental heating; the constant temperature maintenance mode can be used for scenarios where the temperature of the hot plate is within the heat preservation range; the power reduction output mode can be used for scenarios where the temperature of the hot plate is too high, the power supply is limited, or the total power consumption needs to be reduced; and the stop output mode can be used for scenarios such as no-load standby, plate removal, low power protection, or abnormal protection.

[0101] The aforementioned heating drive control signals may include duty cycle control signals, switching control signals, current control signals, or power level control signals, etc. These heating drive control signals correspond to the heat preservation output modes. For example, in the heating output mode, the heating drive control signal can cause the heating module to output at a higher duty cycle; in the constant temperature maintenance mode, the heating drive control signal can cause the heating module to maintain the duty cycle output; in the power reduction output mode, the heating drive control signal can reduce the output duty cycle or switch to a lower power level; and in the stop output mode, the heating drive control signal can turn off the heating module.

[0102] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can determine the corresponding heat preservation output mode of the heating module based on the target heat preservation power control strategy. The platform can determine whether the heating module is in a heating output mode, a constant temperature maintenance mode, a power reduction output mode, or a stop output mode based on the power range of the target heat output power, the current temperature state, and the target linkage scenario.

[0103] For example, when the target thermal output power is the higher power allowed within the current power range, it can be determined as a heating output mode; when the target thermal output power corresponds to the stable power required to maintain heat preservation, it can be determined as a constant temperature maintenance mode; when the target thermal output power is lower than the original thermal output power, it can be determined as a power reduction output mode; and when the target thermal output power is zero power or heating shutdown power, it can be determined as a stop output mode. The aforementioned lighting and heat preservation power linkage control platform can generate a heating drive control signal based on the target thermal output power and send the heating drive control signal to the heating module to control the heating module to execute the corresponding heat preservation output control.

[0104] By using the above methods and steps, the actual output mode of the heating module can be kept consistent with the target thermal output power, and the switching between heating, constant temperature, power reduction and output stop has a clear control basis.

[0105] Optionally, the step of controlling the output of the lighting component and the lighting indication state corresponding to the current heat preservation output control state of the heating module based on the target lighting control strategy further includes: obtaining the current heat preservation output control state of the heating module; determining the lighting indication mode corresponding to the current heat preservation output control state based on the target lighting control strategy, wherein the lighting indication mode includes at least one of the following: heating indication mode, constant temperature indication mode, power reduction indication mode, standby indication mode, and protection indication mode; generating a lighting drive control signal based on the lighting indication mode and the target lighting output parameters, wherein the target lighting output parameters include at least one of the following: lighting brightness, flashing frequency, display color, and on / off duty cycle; controlling the output of the lighting component and the corresponding lighting indication state based on the lighting drive control signal; and updating the lighting drive control signal when the current heat preservation output control state changes, so that the lighting indication state is consistent with the current heat preservation output control state.

[0106] In this embodiment of the invention, the aforementioned current heat preservation output control state refers to the actual heat preservation output state executed by the heating module at the current moment. This current heat preservation output control state can be jointly determined by the target heat output power, the heating drive control signal, and the target linkage scenario. For example, when the heating module supplements heat at a higher power, it corresponds to a heating output state; when it maintains the temperature of the hot cutting board at a stable power, it corresponds to a constant temperature maintenance state; when it operates at a limited power, it corresponds to a power reduction output state; and when the heating module is turned off, it corresponds to a stop output state. This current heat preservation output control state can serve as a direct basis for light indication, so that the light component no longer only displays the on / off state, but changes according to the actual output state of the heating module.

[0107] The aforementioned light indicator modes refer to the indicator methods used by the light components under different heat preservation output control states, including heating indicator mode, constant temperature indicator mode, power reduction indicator mode, standby indicator mode, and protection indicator mode. For example, the heating indicator mode can be used to indicate that the equipment is replenishing heat, the constant temperature indicator mode can be used to indicate that the equipment is in stable heat preservation, the power reduction indicator mode can be used to indicate that the heat output is limited by power or temperature, the standby indicator mode can be used to indicate no-load or no heating after the panel is removed, and the protection indicator mode can be used to indicate protection states such as low power, over-temperature, or abnormal sampling.

[0108] The aforementioned target lighting output parameters can refer to the actual output parameters of the lighting components determined under the target lighting control strategy, including at least one of the following: lighting brightness, flashing frequency, display color, and on / off duty cycle. These target lighting output parameters can be adjusted in conjunction with energy-saving constraints. For example, in a low-battery state, the lighting brightness or on / off duty cycle can be reduced; in a fault protection state, necessary flashing indicators can be retained; and in an idle standby state, low-power constant lighting or intermittent indicators can be used.

[0109] The aforementioned lighting drive control signal can refer to the control signal that drives the lighting component to display according to the target lighting output parameters, including brightness control signal, color control signal, flashing control signal, or duty cycle control signal. This signal can be generated by the aforementioned lighting and heat preservation power linkage control platform based on the lighting prompt mode and the target lighting output parameters, and sent to the lighting component so that the lighting component outputs a lighting prompt state consistent with the current heat preservation output control state of the heating module.

[0110] In one possible embodiment, the aforementioned lighting and heat preservation power linkage control platform can acquire the current heat preservation output control state of the heating module and determine the lighting prompt mode corresponding to the current heat preservation output control state based on the target lighting control strategy. When the current heat preservation output control state is a heating output state, the aforementioned lighting and heat preservation power linkage control platform can determine the lighting prompt mode as a heating prompt mode; when the current heat preservation output control state is a constant temperature maintenance state, it can determine the lighting prompt mode as a constant temperature prompt mode; when the current heat preservation output control state is a power reduction output state, it can determine the lighting prompt mode as a power reduction prompt mode; when the current heat preservation output control state is a stop output state, it can further determine the mode as a standby prompt mode or a protection prompt mode according to the target linkage scenario.

[0111] The aforementioned lighting and insulation power linkage control platform can generate lighting drive control signals based on the lighting prompt mode and target lighting output parameters, and control the lighting components to output corresponding lighting prompt states based on the lighting drive control signals.

[0112] When the current heat preservation output control state changes, the aforementioned lighting and heat preservation power linkage control platform can synchronously update the lighting drive control signal. For example, when the hot plate switches from heating output to constant temperature maintenance, the lighting indicator status synchronously switches from heating indicator to constant temperature indicator; when the power decreases, causing the heating module to switch from constant temperature maintenance to reduced power output, the lighting indicator status synchronously switches to power limited indicator; when the heating module stops outputting after the plate is removed, the lighting indicator status synchronously switches to standby indicator.

[0113] The above method enables the indicator light status to be updated synchronously with the heat preservation output control status of the heating module, reducing the problem of inconsistency between the indicator light display and the actual heating status.
