Description

Technical Field

[0001] This application relates to the technical field of device charging, and in particular to methods, apparatus, devices and storage media for charging multiple devices. Background Technology

[0002] With the development of battery technology, more and more electrical appliances are starting to use rechargeable batteries, and wireless charging devices with different power are being used based on different rechargeable battery capacities. The existing wireless charging technologies mainly include four basic methods: electromagnetic induction, magnetic resonance, electric field coupling, and radio wave.

[0003] Electromagnetic induction technology utilizes the principle of electromagnetic induction, where alternating current flows through a transmitting coil to generate a changing magnetic field. The transmitting coil then generates current under this changing magnetic field, thus charging the receiving device. Magnetic resonance technology achieves resonance by matching the transmitting and receiving frequencies, thereby enhancing transmission efficiency. Electric field coupling technology transfers transmitted electrical energy to the receiving device through an electric field, utilizing the induced electric field generated by two sets of asymmetric dipoles coupled in a perpendicular direction to transmit electrical energy. Radio wave technology converts electromagnetic waves into current and transmits the current through a circuit, but it has disadvantages such as short transmission distance, low conversion efficiency, and high radiation.

[0004] Based on the aforementioned wireless charging technology, the applicant believes that at least the following problems exist: existing wireless charging devices can only be adapted to devices with rated power and cannot perform wireless charging operations on multiple electrical devices. Summary of the Invention

[0005] To address the issue that existing wireless charging devices cannot wirelessly charge multiple devices due to their limited power rating, this application provides a multi-device charging method and system.

[0006] In a first aspect, this application provides a multi-device charging method, employing the following technical solution: the method is applied to a wireless charging device, the wireless charging device having a plurality of pressure sensors internally configured, and the method includes:

[0007] Acquire pressure sensing information, including pressure location information;

[0008] The system searches for the charging coil model corresponding to the pressure position information in the preset pressure coil library. The preset pressure coil library stores different pressure position information and the charging coil model corresponding to each pressure position information.

[0009] The corresponding charging coil will be activated based on the charging coil model to perform the charging operation.

[0010] The above technical solution acquires corresponding pressure sensing information, including pressure position information, through a pressure sensor. Based on the pressure position information, the device retrieves the corresponding charging coil model from a preset pressure coil library. The device then activates the corresponding charging coil to perform the charging operation based on the charging coil model. The device also retrieves the number of devices to be charged at different locations based on the pressure sensing information and directly activates the corresponding charging coil to perform the charging operation. This allows the device to wirelessly charge multiple devices simultaneously, thereby improving charging efficiency.

[0011] In one specific implementation scheme, the step of activating the corresponding charging coil according to the charging coil model to perform the charging operation includes:

[0012] Count the amount of pressure sensor data;

[0013] When the amount of pressure sensor information exceeds a preset standard value, charging image information is acquired.

[0014] Calculate the inductive distance between the charging device and the charging coil based on the charging image information;

[0015] Determine if the sensing distance value is within the preset charging range;

[0016] If so, the corresponding charging coil model is obtained based on the charging image information;

[0017] The corresponding charging coil will be activated based on the charging coil model to perform the charging operation.

[0018] By employing the above technical solution, the number of pressure sensing data is counted. When the number of pressure sensing data exceeds a preset standard value, charging image information is acquired. Based on the charging image information, the sensing distance between the charging device and the charging coil is calculated, and it is determined whether the sensing distance is within a preset charging range. If so, the corresponding charging coil model is obtained based on the charging image information, and the corresponding charging coil is activated to perform the charging operation. This reduces the possibility that the charging device may be placed between two charging coils, causing the system to fail to activate the corresponding charging coil to perform the charging operation, thereby improving the accuracy of the system's charging operation.

[0019] In one specific implementation scheme, the step of activating the corresponding charging coil according to the charging coil model to perform the charging operation includes:

[0020] Obtain charging quantity information, wherein the charging quantity information is the number of devices to be charged;

[0021] Collect statistics on the models of charging coils within the charging range;

[0022] The corresponding charging coil will be activated based on the charging coil model to perform the charging operation.

[0023] Determine if the number of charging coils matches the charging quantity information;

[0024] If they are not equal, the charging coil models will be sorted in descending order according to their distance from the charging device.

[0025] The charging coils are activated sequentially in descending order to perform the charging operation until the number of charging coils matches the number of charges.

[0026] The above technical solution obtains charging quantity information based on charging image information, counts the charging coil models within the charging range, and activates the corresponding charging coil to perform charging operations based on the charging coil model. It then determines whether the number of charging coils matches the charging quantity information. If not, the distance values ​​between the charging coil models and the charging devices are sorted in descending order, and the charging coils are activated sequentially in descending order until the number of charging coils matches the charging quantity information. This reduces the possibility of a single charging coil needing to charge multiple devices due to excessively close distances between the charging coils and multiple devices, ensuring that each charging device corresponds to one charging coil, thereby improving the strict one-to-one correspondence between charging devices and charging coils.

[0027] In one specific implementation, after the charging coils are activated sequentially in descending order to perform charging operations until the number of charging coils equals the number of charges, the method further includes:

[0028] The system queries the charging equipment information corresponding to the charging image information in a preset charging equipment model database. The charging equipment model database stores different charging equipment model information and standard charging power information corresponding to each charging equipment model information.

[0029] Obtain the charging coil model corresponding to the charging device model information;

[0030] Obtain the actual charging power information corresponding to the charging coil model;

[0031] Adjust the actual charging power information until it is equal to the standard charging power information.

[0032] Through the above technical solution, the corresponding charging device model information is identified based on the charging image information, the standard charging power information relative to the current charging device model information is obtained based on the charging device model information, the actual charging power information corresponding to each charging coil is obtained based on the charging image information, and the power of the charging coil is adjusted until the actual charging power information is equal to the standard charging power information. This allows the system to automatically adjust the corresponding actual charging power information according to the charging device model information, thereby improving charging efficiency.

[0033] In one specific implementation, the method further includes:

[0034] Obtain the actual power information of the charging coil;

[0035] The actual power information is compared with the preset standard power range;

[0036] If the actual power information is outside the preset standard power range, the corresponding charging coil will stop charging.

[0037] Start the timer and obtain verification timer information;

[0038] When the verification timing information reaches the preset standard verification range, restart the charging coil to perform the charging operation.

[0039] Obtain verification power information;

[0040] If the verified power information is outside the preset standard power range, an alarm message related to the corresponding charging coil will be sent.

[0041] Otherwise, control the charging coil to continue charging.

[0042] The above technical solution obtains the actual power information of the charging coil and compares it with a preset standard power range. If the actual power information is outside the preset standard power range, the charging operation of the corresponding coil is stopped, a timer is started, and verification timer information is obtained. When the verification timer information reaches the preset standard verification range, the charging coil is restarted to perform the charging operation, and the verification power information after restarting is obtained. If the verification power information is still outside the preset standard power range, an alarm message related to the corresponding charging coil is sent. When the coil has abnormal power, the system can automatically pause the charging operation of the coil and restart the coil after a preset time, reducing the possibility of false alarms due to brief coil abnormalities, thereby improving the accuracy of alarm information.

[0043] In one specific implementation, sending alarm information related to the corresponding charging coil includes:

[0044] The verified power information is compared with the preset limit power value;

[0045] If the verified power information is not less than the preset limit power value, then obtain the coil temperature information;

[0046] The coil temperature information is compared with the preset abnormal temperature value;

[0047] If the coil temperature exceeds the abnormal temperature value, the charging device will be powered off.

[0048] Otherwise, send an alarm message related to the corresponding charging coil.

[0049] By employing the above technical solution, when the verification power information is still outside the preset standard power range, the verification power information is compared with the preset limit power value. If the verification power information is not less than the preset limit power value, the coil temperature information is obtained and compared with the preset abnormal temperature value. If the coil temperature information is greater than the abnormal temperature value, the charging device is powered off, reducing the possibility of abnormal output power caused by abnormal coil temperature. This allows the system to automatically power off coils with abnormal temperatures, thereby improving the safety level during the charging process.

[0050] In a specific feasible implementation, when the verification power information is obtained, the number of times the verification power information is obtained corresponding to the charging coil is counted.

[0051] Determine whether the number of power verification attempts is within the preset range of abnormal charging attempts;

[0052] If the number of power verifications is outside the preset range of abnormal charging counts, then obtain the time-current curve corresponding to the charging coil.

[0053] Determine whether the current value corresponding to the time-current curve within a preset time period is within a preset current stability range;

[0054] If the current value is outside the preset current stability range, an abnormal current prompt message corresponding to the charging coil will be sent to the staff's smart terminal.

[0055] By using the above technical solution, the number of verification power times corresponding to the verification power information is counted, and it is determined whether the number of verification power times is outside the preset range of abnormal charging times. If so, the time-current curve corresponding to the charging coil is obtained, and it is determined whether the time-current curve is within the preset current stability range within the preset time. If the current value is outside the preset current stability range, an abnormal current prompt message corresponding to the charging coil is sent to the staff's smart terminal, so that the staff can know in a timely manner whether the output current of the corresponding charging coil is stable. This allows the staff to prioritize the charging coil with stable output current for charging equipment, thereby improving charging efficiency.

[0056] Secondly, this application provides a multi-device charging device, which adopts the following technical solution: the device includes:

[0057] The pressure sensing information acquisition module is used to acquire pressure sensing information, including pressure position information;

[0058] The coil model acquisition module is used to query the charging coil model corresponding to the pressure position information in the preset pressure-sensitive coil library. The preset pressure-sensitive coil library stores different pressure position information and each charging coil model corresponding to the pressure position information.

[0059] The charging coil module is used to activate the corresponding charging coil to perform charging operations based on the charging coil model.

[0060] The above technical solution acquires corresponding pressure sensing information, including pressure position information, through a pressure sensor. Based on the pressure position information, the device retrieves the corresponding charging coil model from a preset pressure coil library. The device then activates the corresponding charging coil to perform the charging operation based on the charging coil model. The device also retrieves the number of devices to be charged at different locations based on the pressure sensing information and directly activates the corresponding charging coil to perform the charging operation. This allows the device to wirelessly charge multiple devices simultaneously, thereby improving charging efficiency.

[0061] Thirdly, this application provides a computer device that adopts the following technical solution: it includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as in any of the above-described multi-device charging methods.

If not, sort the distance values ​​between the charging coil models and the charging devices in descending order, and activate the charging coils in descending order to perform charging operation until the number of charging coils is equal to the charging quantity information. This reduces the possibility of a single charging coil needing to charge multiple devices due to the distance values ​​between the charging coil and multiple devices being too close, ensuring that each charging device corresponds to one charging coil, thereby improving the strict one-to-one correspondence between charging devices and charging coils.

[0071] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0072] This application discloses a multi-device charging method based on a wireless charging system. The wireless charging system can control the power output of the electromagnetic coils by controlling the number of electromagnetic coils. The wireless charging system can obtain corresponding pressure sensing information and coil temperature information based on pressure sensors and temperature sensors preset in the wireless charging device. The wireless charging system can also obtain image information inside the wireless charging device based on a camera preset inside the wireless charging device.

[0073] like Figure 1 As shown, the method includes the following steps:

[0074] S10, acquire pressure sensing information.

[0075] When a user places the device to be charged into the wireless charging device, the pressure sensor preset on the wireless charging device is first triggered. The pressure sensing information includes pressure position information, which is the position information of the device in the wireless charging device.

[0076] S11, obtain the charging coil model.

[0077] The system searches a preset pressure-sensitive coil library for the charging coil model corresponding to the pressure position information. The preset pressure-sensitive coil library stores different pressure position information and the charging coil model corresponding to each pressure position information.

[0078] S12, activate the charging coil to begin charging.

[0079] The system stores different coil model information and each corresponding charging coil in a preset charging coil library. The corresponding coil is activated to perform the charging operation based on the charging coil model.

[0080] In one embodiment, considering that the charging device is located between two coils, it is necessary to statistically analyze the distance between the coils and the charging device. The specific statistical operation can be performed as follows:

[0081] The system counts the number of pressure sensor readings. When the number of readings exceeds a preset standard value, it acquires charging image information and calculates the sensing distance between the charging device and the charging coil based on this information. It then determines whether the sensing distance falls within a preset charging range. If so, it retrieves the corresponding charging coil model from the charging image information and activates the appropriate coil for charging. This allows the system to automatically select the charging coil closest to the charging device based on the charging image information, reducing the possibility of the system being unable to select the appropriate coil if the device is located between two charging coils, thus improving charging efficiency. For example, if charging device A is located between charging coils B and C, and the distance between A and B is M, and the distance between A and C is N, where M < N, then charging coil B is preferentially selected to charge device A.

[0082] In one embodiment, considering that there is a one-to-one correspondence between the charging coil and the charging device, it is necessary to perform statistics on the charging device and the charging coil separately. The specific statistical operation can be performed as follows:

[0083] The system acquires the number of devices to be charged, and counts the models of charging coils within the charging range. Based on these models, the corresponding charging coil is activated to begin charging. The system checks if the number of charging coils matches the number of devices. If not, the charging coil models are sorted in descending order of their distance from the devices, and charging coils are activated sequentially until the number of coils matches the number of devices. This ensures a strict one-to-one correspondence between charging devices and charging coils, reducing the possibility of a coil needing to charge multiple devices due to proximity. This guarantees that all devices are charged, improving charging stability. For example, if the number of devices is 3 and the number of charging coils is 2, the coils are sorted in descending order of their distance from the devices, and charging coils are activated sequentially until the number of coils reaches 3.

[0084] In one embodiment, considering the need to monitor charging power, the specific monitoring operation can be performed as follows:

[0085] After sequentially activating the charging coils in descending order until the number of charging coils equals the number of devices to be charged, the system stores different charging device model information and corresponding standard charging power information in a preset charging device model library. It then retrieves the charging coil model corresponding to the charging device model, obtains the actual charging power information corresponding to the charging coil model, and adjusts the actual charging power information until it equals the standard charging power information. This allows the system to automatically obtain the charging device model from image information and adjust the actual output power of the corresponding charging coil to equal the standard output power, thereby improving the charging efficiency. For example, if the preset standard charging power information for a charging device is S, and the detected actual output power is D, and the actual output power D is less than the standard charging power information S, then the actual output power is increased until it reaches S.

[0086] It is worth mentioning that when the charging device model information is not stored in the preset charging device model library, the charging type information of the current charging device is identified, and the safe power range in the preset charging type library is obtained. The preset charging type library stores different charging type information and the safe power range corresponding to each charging type information. The charging operation is performed on the charging device so that the actual output power of the charging coil is within the preset safe power range, so that the unknown model of the charging device can be charged within the safe power range, thereby improving the safety performance of the charging device when charging.

[0087] In one embodiment, considering that when charging the charging device, the standard charging power corresponding to the charging device is greater than the maximum output power of the charging coil, the actual output power of the charging coil is made equal to the maximum output power of the charging coil, thereby reducing the possibility that the charging coil power is less than the standard charging power of the charging device, which would cause the charging coil power to be continuously controlled to increase.

[0088] In one embodiment, considering the possibility of system errors when the actual output power is abnormal, it is necessary to perform a verification operation on the abnormal output power. The specific verification operation can be performed as follows:

[0089] The system compares the actual power information of the charging coil with a preset standard power range. If the actual power information is outside the preset standard power range, the charging operation of the corresponding charging coil is stopped, a timer is started, and verification timer information is acquired. When the verification timer information reaches the preset standard verification range, the charging coil is restarted to continue charging, and verification power information is acquired. If the verification power information is outside the preset standard power range, an alarm message related to the corresponding charging coil is sent; otherwise, the charging coil continues to charge. This reduces the possibility of false alarms due to system malfunctions, thereby improving the accuracy of alarm information. For example, if the preset standard power range is 5-100W and the actual power information is 120W, the charging operation is first stopped, a timer is started, and verification timer information is acquired until the verification timer information reaches the preset standard verification range. Then, the charging coil is restarted to continue charging, and verification power information is acquired. If the verification power information is within the preset standard power range, the alarm message is canceled; if the verification information is still outside the preset standard power range, an alarm message such as "abnormal output power" is sent.

[0090] In one embodiment, considering that the verification power information is much larger than the preset standard power range, it is necessary to monitor the temperature information of the charging coil. The specific monitoring operations include:

[0091] The system compares the verified power information with a preset limit power value. If the verified power information is not less than the preset limit power value, the corresponding coil temperature information is obtained and compared with a preset abnormal temperature value. If the coil temperature information is greater than the abnormal temperature value, the charging device is powered off; otherwise, an alarm message related to the corresponding charging coil is sent. This allows the system to promptly power off charging coils with abnormal temperatures, thereby improving the safety of the charging coil during the charging process. For example, if the verified power information is 200W and the corresponding limit power value is 150W, and the obtained coil temperature information is 55℃ while the preset abnormal temperature value is 45℃, the coil is powered off; if the obtained coil temperature information is 40℃, the charging operation continues.

[0092] In one embodiment, considering that the stability of the current value corresponding to the charging coil needs to affect the charging efficiency, it is necessary to detect the stability of the current value. The specific detection operation can be performed as follows:

[0093] The system counts the number of times the charging coil receives verification power information; it determines whether the number of verification power counts is within a preset range of abnormal charging counts; if the number of verification power counts is outside the preset range of abnormal charging counts, it acquires the time-current curve corresponding to the charging coil; it determines whether the current value corresponding to the time-current curve within a preset time is within a preset current stability range; if the current value is outside the preset current stability range, it sends an abnormal current prompt message corresponding to the charging coil to the staff's smart terminal; this allows the system to automatically perform current value stabilization operations on the charging coil that receives the verification power information, thereby improving the stability of the charging coil.

[0094] It is worth mentioning that after determining that the current value corresponding to the charging coil is unstable, the corresponding charging coil is set as the second priority, and the current value corresponding to the charging coil that is within the preset stable range is set as the first priority. The power value of the charging device is obtained. If the number of charging devices in the first priority is less than the number of devices to be charged, the charging devices are sorted according to their power values, so that the devices to be charged with more power values ​​use the charging coil of the first priority for charging operation, so that the charging coil of the first priority can complete the charging operation as soon as possible, thereby improving the charging efficiency.

[0095] The implementation principle of this application embodiment is as follows: acquire pressure sensing information and charging image information, calculate the sensing distance value between the device to be charged and the charging coil based on the charging image information, start the closest charging coil to charge the device to be charged based on the sensing distance value, check whether the number of devices to be charged and the number of charging coils are equal, if they are not equal, start the corresponding charging coil to charge the device to be charged.

[0096] Based on the above method, this application also discloses a multi-device charging device.

The preset pressure-sensitive coil library stores different pressure position information and each charging coil model corresponding to the pressure position information.

[0100] The charging coil charging module 203 is used to activate the corresponding charging coil to perform charging operations according to the charging coil model.
