Description

Technical Field

[0001] The present application belongs to the technical field of power adapters, and in particular, relates to an overload regulation method, device, and storage medium. Background Art

[0002] With the widespread use of smart devices and electronic products, multi-port power adapters have become an indispensable accessory in daily life. Traditional power adapters usually use a simple power-off protection mechanism in overload conditions. When the current exceeds the set value, the power is immediately disconnected to protect the safety of the device. However, this method has significant shortcomings in multi-port power adapters. First, since each port may power different devices at the same time, the load conditions are often uneven, resulting in some ports being overloaded while other ports are unloaded. This uneven current distribution not only affects the effective use of resources, but may also cause damage to the device or overheating of the adapter, thereby posing a safety hazard. In addition, the existing technology generally lacks dynamic monitoring and adjustment means for the real-time status of the power adapter, and cannot effectively cope with complex current changes and the simultaneous operation of multiple ports.

[0029] See also Figure 1 , Figure 1 : is a schematic flow chart of the overload regulation method provided in the first embodiment of the present application. In this embodiment, the execution subject of the overload regulation method is a device with an overload regulation function, which can be a multi-port power adapter, or a computer or a server. Figure 1 The overload regulation methods shown include: S101: Acquire real-time temperature information of the power adapter.

[0030] In this embodiment, a temperature sensor (such as an NTC thermistor) can be used to monitor the temperature data of the housing and the interior of the power adapter in real time.

[0031] The temperature sensor can be connected to the microcontroller to periodically collect and store temperature information, and obtain the real-time temperature information of the power adapter based on the periodically collected temperature information to ensure that each current regulation decision is based on the current temperature.

[0032] For example, the MCU is set to collect temperature information every 1 second and store it in the internal data cache to ensure that the collected temperature information is the latest.

[0033] S102: Obtaining first working state information of the power adapter according to the real-time temperature information.

[0034] In this embodiment, a strategy for obtaining the first working status information can be pre-set, wherein the first working status information is the device operating status determined based on the real-time temperature information of the power adapter, which is used to reflect the thermal condition of the power adapter, and is used to monitor the overall thermal condition of the power adapter, to help take emergency measures when the temperature is abnormal, such as triggering overload detection, to protect the safety of the device and the user.

[0035] The acquisition strategy may be a correspondence between preset temperature information and preset working state information of the power adapter, wherein the preset temperature information may be a preset temperature range, and the preset working state information of the power adapter may be "overheated", "abnormal" or "normal". For example: 0°C ≤ Temperature<60°C, the first working status information can be judged as "normal", 60°C ≤ Temperature<85°C, the first working status information can be judged as "abnormal", When the temperature is ≥ 85°C, the first working state information can be judged as "overheating".

[0036] The first working state information of the power adapter is used to trigger subsequent overload detection. For example, when the temperature exceeds 85°C, the MCU identifies the first working state information as "overheating" and triggers the subsequent overload detection function.

[0037] S103: If the first working state information meets a preset overload detection standard, real-time current information of each port is obtained.

[0038] The device pre-sets an overload detection standard to determine whether the first working state information meets the preset overload detection standard. For example, if the first working state information is "abnormal", the real-time current information of each port is obtained.

[0039] Among them, the current information can be measured by a current sensor and converted into a digital signal by an analog-to-digital converter, so as to obtain the real-time current information of each port.

[0040] S104: Acquire second working state information of each of the ports according to the real-time current information of each of the ports.

[0041] In this embodiment, a strategy for obtaining the second working status information can be pre-set, wherein the second working status information is a detailed operating status determined based on real-time current information of each port of the power adapter, and is used to reflect the load condition of each port and to monitor the load condition of each port so that corresponding adjustment measures can be taken when an overload occurs to ensure stable operation and safety of the equipment.

[0042] According to the real-time current information of each port, the second working state information of each port can be obtained. A rated current value is set for each port, such as the rated current of port A is 2A. If the current of a port exceeds the rated value, the second working state information of the port is "overload".

[0043] Specifically, the difference between the real-time current information and the rated current can be detected. According to the difference between the rated current and the actual current of the device, it is determined whether to enter the overload protection mode.

[0044] Where ΔI is the current difference, I current is the real-time current information, I previous is the current information sampled last time, and ∆t is the sampling time interval.

[0045] If ΔI>δ, where δ is the set current change threshold, the current is considered abnormal, and the second working state information of the port is "overload", triggering the overload protection mechanism and entering the current regulation stage. By detecting the rate of current change, the overload trend can be detected earlier, avoiding slow system response and increasing the system's response speed to sudden overloads.

[0046] S105: If the second working state information of the port meets a preset overload adjustment standard, obtain maximum current information of the overload port and rated current information of the overload port.

[0047] In this embodiment, an overload adjustment standard is preset, and whether it is necessary to obtain the maximum current information of the overload port and the rated current information of the overload port is determined according to the preset overload adjustment standard. When the MCU detects that the status of a port is "overloaded", the maximum current value and the rated current value of the port are recorded. For example, if the current of port B is 2.5A, its maximum current is recorded as 2.5A, and the rated current is set to 1.5A.

[0048] Specifically, the rated current of each port can be preset, for example, the rated current of port A is 2A, and the rated current of port B is 1.5A.

[0049] Connect a current sensor to each port to monitor the current output of each port in real time. The output signal of the current sensor is converted into a digital signal by the ADC for processing by the MCU. The MCU reads the real-time current value from the current sensor regularly (for example, once a second).

[0050] After each reading of the real-time current, check whether the current exceeds the currently stored maximum current value. If it exceeds, update the maximum current variable.

[0051] While acquiring and updating the current, it is also necessary to check whether the current exceeds the rated value to determine whether the port is in an overload state.

[0052] When determining the overload state, ensure that the maximum current and rated current of each port are available in the MCU's memory for subsequent control and adjustment.

[0053] For example, assume that both port A and port B are working under the same load, and the MCU reads once per second: 1st second: port A current is 1.5A, port B current is 1.0A. Port A maximum current information maxCurrentA = 1.5A, port B maximum current information maxCurrentB = 1.0A. 2nd second: port A current is 1.8A, port B current is 1.6A. Update maxCurrentA = 1.8A, maxCurrentB = 1.6A. 3rd second: port A current is 2.1A (exceeding the rated 2A), entering the overload state. At this time, maxCurrentA = 2.1A and ratedCurrentA = 2.0A are recorded.

[0054] Through the above steps, the MCU can dynamically obtain the maximum current information of the overload port and the rated current information of the overload port, and can make reasonable adjustments and decisions according to the information at any time.

[0055] S106: Adjust the current information of the overload port according to the maximum current information of the overload port, the rated current information of the overload port and a preset first overload adjustment formula.

[0056] The first overload adjustment formula may be preset. For example, a simple adjustment formula is set: adjusted current = rated current * k, where k is an adjustment coefficient used to control the adjustment amplitude, and is generally set to be less than 1 (e.g., for 1.0, the current is the rated current, and for 0.8, it is reduced by 20%).

[0057] You can select an appropriate adjustment factor k based on the specific application scenario and safety considerations. For example: k = 0.8, which means reducing the current to 80% of the rated current. This value can be configured through system parameters or hard-coded.

[0058] According to the existing maximum current and rated current information, an adjusted current value is calculated based on a first overload adjustment formula.

[0059] After calculating the adjusted current value, the output of the power adapter can be adjusted through the output control logic. Here, the output current is usually adjusted by pulse width modulation, analog output or direct switch control.

[0060] The actual output current must continue to be monitored after regulation to ensure that regulation is effective and stable. If the actual current still exceeds the rated value, it may be necessary to re-evaluate the regulation strategy or implement tighter limits. For example, set up a monitoring loop to check the actual port current every one second and further adjust the output as needed.

[0061] Assume that the rated current of port B is 1.5 A and the current maximum current is 2.5 A. We choose the adjustment factor k = 0.8.

[0062] Use the formula to calculate the adjusted current: Adjusted current = 1.5A *0.8 = 1.2A Then, the control function is called to adjust the output current of port B to 1.2 A. In the subsequent monitoring process, if the current read in real time exceeds 1.2 A, the output is adjusted again.

[0063] In one implementation, based on the maximum current information of the overload port , Rated current information of overload ports And the preset first overload adjustment formula adjusts the current information of the overload port ; The preset first overload adjustment formula is as follows: in, is the load regulation factor, Overload degree information.

[0064] Adjust the current information of the overload port Indicates the actual current required under specific conditions such as load, temperature, and duty cycle. Overload port current rating information It is the current designed or calibrated for the equipment under normal operating conditions. It serves as a reference value for adjusting the actual current based on other parameters.

[0065] The load adjustment factor indicates the correction ratio of the rated current under overload conditions. When the load increases, this factor will affect the adjusted current.

[0066] Overload degree information describes the ratio of the current operating load of the equipment to the rated load. It helps quantify the performance of the equipment under overload conditions.

[0067] In another embodiment, if Figure 2 As shown, S106 may include S1061-S1062, and S1061-S1062 are specifically as follows: S1061: Acquire rated temperature information of the power adapter, temperature coefficient information corresponding to the power adapter, and unit temperature change information corresponding to the power adapter.

[0068] In this embodiment, the rated temperature information refers to the temperature range allowed by the power adapter under normal working conditions. The rated temperature value of the adapter can be obtained by querying the product manual of the power adapter or the technical specifications provided by the manufacturer. This value is usually the highest or lowest temperature at which the adapter can operate safely and stably when working in a specific environment.

[0069] Temperature coefficient information refers to the ratio of the change in the performance parameters of the power adapter (such as output voltage, output current, etc.) when the temperature range is increased or decreased. The temperature coefficient is usually provided by the manufacturer and indicates the sensitivity of the device performance to temperature changes. This can be obtained from the manufacturer's official website or included in the technical data sheet of the power adapter.

[0070] Unit temperature change information indicates the impact on the adapter performance under a unit temperature change, usually expressed as a percentage or absolute value. Unit temperature change information refers to the change in power adapter performance (such as output current, power, etc.) under a unit temperature change (such as per degree Celsius).

[0071] S1062: Adjust the current information of the overload port according to the real-time temperature information, the rated temperature information, the temperature coefficient information, the unit temperature change information, the maximum current information of the overload port, the rated current information of the overload port and a preset second overload adjustment formula.

[0072] A second overload adjustment formula is predefined, and the formula can dynamically adapt the output current based on factors such as real-time temperature information, rated temperature information, temperature coefficient information, unit temperature change information, maximum current information of the overload port, and rated current information of the overload port.

[0073] Specifically, the real-time temperature information , Rated temperature information , Temperature coefficient information , Unit temperature change information , Maximum current information of overload port , Rated current information of overload ports And the preset second overload adjustment formula adjusts the current information of the overload port ; The preset second overload adjustment formula: in, is the load regulation factor, For overload level information, Temperature impact information.

[0074] Adjust the current information of the overload port Indicates the actual current required under specific conditions such as load, temperature, and duty cycle. Overload port current rating information It is the current designed or calibrated for the equipment under normal operating conditions. It serves as a reference value for adjusting the actual current based on other parameters.

[0075] The load adjustment factor indicates the correction ratio of the rated current under overload conditions. When the load increases, this factor will affect the adjusted current.

[0076] Overload degree information describes the ratio of the current operating load of the equipment to the rated load. It helps quantify the performance of the equipment under overload conditions.

[0077] The temperature coefficient is used to quantify the ratio of the change of physical quantities (such as resistance and conductivity) with temperature. It can help understand the changes in the performance of materials at different temperatures.

[0078] It refers to the change in a specific physical quantity (such as resistance or conductivity) when the temperature changes by a unit. Closely related, and often used to measure a material's temperature sensitivity.

[0079] The rated temperature designed or marked for a device under normal operating conditions indicates the standard temperature at which the device can operate normally under the design and test conditions. It serves as a comparative benchmark to quantify the effects of temperature changes.

[0080] In this implementation, by integrating multiple factors, a comprehensive consideration of device performance is provided to ensure the reliability and effectiveness of the device under various conditions during design and operation. Each parameter helps to better understand and adjust the current to adapt to changes in the working environment.

[0081] In one implementation, in order to save the adjustment calculation of the unloaded port, reduce the calculation burden of the system and improve the operation efficiency, it is possible to detect whether there is an unloaded port. Figure 3 As shown, after S106, S107 to S111 may also be included, and S107 to S111 are specifically as follows: S107: Acquire the real-time port voltage of each of the ports.

[0082] Real-time port voltage refers to the voltage value of each port of the power adapter measured at a specific moment. The voltage of each output port of the power adapter is detected in real time using a voltage sensor or an integrated measurement circuit. The data acquisition system reads and records these voltage values ​​at regular intervals.

[0083] S108: Obtaining the real-time port power of each of the ports according to the real-time port voltage of each of the ports and the real-time current information of each of the ports.

[0084] Get real-time current information for each port, either through a current sensor or by reading the data from the power module directly. Use the following formula to calculate power: P = V *I Among them, P is power, V is the real-time port voltage of the port, and I is the real-time current information of each port.

[0085] S109: Acquire the previous historical port power of each of the ports.

[0086] Historical port power refers to the power value measured at a certain time before. The device needs to record the historical power, which can be recorded in data logs, stored in databases, etc. The historical power of each port will be updated and saved regularly for subsequent comparative analysis.

[0087] S110: Identify an unloaded port among the ports according to the real-time port power of the ports and the previous historical port power of the ports.

[0088] An unloaded port is a port that is not connected to a load or to a load so small that the output power is almost zero.

[0089] The current real-time power is compared with the historical power. If the current power is close to zero and is significantly different from the historical power (such as a design threshold), the port can be identified as an unloaded port.

[0090] The real-time port voltage is , the real-time port power is , the real-time port power is , the previous historical port power is ,but .

[0091] Indicates the port power change. and It means that the port is an unloaded port. Among them, ε is the power change threshold, P threshold is the power threshold.

[0092] S111: canceling the overload adjustment calculation for the unloaded port.

[0093] After identifying the unloaded ports, the system updates its control algorithm to stop current regulation calculations for these ports, ensuring that the system continues to regulate only for the connected load. It is possible to implement this logic by setting a flag: a port with an unloaded flag set to "true" is excluded from the regulation calculation.

[0094] In this embodiment, by introducing the trend judgment of power change, unloaded ports can be identified when the power change is small but the absolute power is low, thereby avoiding unnecessary calculations and improving identification accuracy.

[0095] In the case of an unloaded port, by considering the influence of temperature change and duty cycle, the output of the power adapter can be controlled more accurately, thereby ensuring its stable performance under different working conditions. Figure 4 As shown, S106 may include S1063 to S1064, and S1063 to S1064 are specifically as follows: S1063: Obtain duty ratio information between the unloaded port and all the ports, and obtain rated temperature information of the power adapter, temperature coefficient information corresponding to the power adapter, and unit temperature change information corresponding to the power adapter.

[0096] The duty ratio information refers to the ratio of the time that the signal is in an active state within a specific time period, which is usually expressed as a percentage. In this embodiment, the relative occupancy of the unloaded port and other working ports is reflected.

[0097] According to the real-time monitoring system, calculate the duty cycle of the unloaded port on all ports. The duty cycle usually refers to the ratio of the time that the unloaded port is in the "on" state to the total time in a cycle. You can use a standard time recording mechanism to sample the enable and close time of the unloaded port within a period of time and calculate the proportion.

[0098] S1064: Adjust the current information of the overload port according to the duty cycle information, the real-time temperature information, the rated temperature information, the temperature coefficient information, the unit temperature change information, the maximum current information of the overload port, the rated current information of the overload port and a preset third overload adjustment formula.

[0099] A third overload adjustment formula can be set in advance to calculate the adjusted current value based on duty cycle information, real-time temperature information, rated temperature information, temperature coefficient information, unit temperature change information, maximum current information of the overload port, rated current information of the overload port and the preset third overload adjustment formula.

[0100] Specifically, in one implementation, according to the duty ratio information , the real-time temperature information , the rated temperature information , the temperature coefficient information , the unit temperature change information , the maximum current information of the overload port , Rated current information of the overload port and a preset second overload adjustment formula to adjust the current information of the overload port ; The preset third overload adjustment formula: in, is the load regulation factor, For overload level information, For temperature impact information, is the duty ratio adjustment coefficient.

[0101] In an embodiment of the present application, the real-time temperature information of the power adapter is obtained; the first working state information of the power adapter is obtained according to the real-time temperature information; if the first working state information meets the preset overload detection standard, the real-time current information of each port is obtained; according to the real-time current information of each port, the second working state information of each port is obtained; if the second working state information of the port meets the preset overload adjustment standard, the maximum current information of the overloaded port and the rated current information of the overloaded port are obtained; according to the maximum current information of the overloaded port, the rated current information of the overloaded port and the preset first overload adjustment formula, the current information of the overloaded port is adjusted. By obtaining the real-time temperature information of the power adapter, the working state of the adapter can be judged. After confirming that there is an overload situation, the real-time current information of each port can be obtained, and the working state of each port can be analyzed. The above scheme specifically handles the current anomalies of different ports, thereby optimizing the current distribution and preventing overload of a certain port. Through the preset overload adjustment standard, the maximum current information and rated current information of the overloaded port can be obtained, and the actual current of the overloaded port can be adjusted according to this information. The adjustment method in this embodiment comprehensively considers the real-time status of the power adapter and the load conditions of each port, which not only ensures that the device works safely within the normal range, but also maximizes the resource utilization efficiency of the multi-port power adapter. In particular, when multiple ports work simultaneously, resource allocation is optimized and the safety and stability of the power adapter are ensured.
