[0023] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further describes the exemplary embodiments of the present application in detail with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] Example 1

[0025] This embodiment provides a drying control method that can be used to dry clothes in a drying device, especially applied to a dryer, such as a dryer suitable for homes and hotels.

[0026] As Figure 1 shown, the drying control method provided in this embodiment includes:

[0027] Step 101: Obtain the moisture content of the clothes.

[0028] The moisture content of the clothes can be obtained in various ways. When the clothes are placed in the drying drum, the humidity inside the drying drum can be collected by a humidity sensor, and then the moisture content of the clothes can be obtained. It is also possible to obtain the moisture content of the clothes by weighing the drying drum. It is also possible to use a temperature sensor to collect the temperature inside the drying drum and combine it with the humidity to confirm the moisture content of the clothes.

[0029] Step 102: Determine the drying mode according to the moisture content of the clothes.

[0030] The drying modes include: the first drying mode, the second drying mode, and the third drying mode; in the first drying mode, the first drying device and the second drying device are simultaneously started to perform the drying operation; in the second drying mode, the first drying device is started to perform the drying operation; in the third mode, the second drying device is started to perform the drying operation.

[0031] The first drying device and the second drying device can be the same device or different devices. For example, both the first drying device and the second drying device can be heaters, or the first drying device is a heater and the second drying device is a heat pump. Both the heater and the heat pump are used to increase the temperature of the air in the drying channel and generate hot air. In addition, the first drying device and the second drying device also include a fan for blowing the hot air into the drying drum.

[0032] Determine the drying mode according to the moisture content of the clothes. For example, when the moisture content is relatively high, select the first drying mode and simultaneously start the first drying device and the second drying device to perform the drying operation. When the moisture content is relatively low, one of the drying devices can be started, either the first drying device or the second drying device.

[0033] Step 103: Determine the drying parameters for the drying mode.

[0034] The drying parameters include at least one of: drying temperature, drying time, fan speed, and drying speed.

[0035] After determining the drying mode and the drying device to be started, at least one of the drying temperature, drying time, fan speed, and drying speed can be set.

[0036] The drying temperature is the temperature of the hot air input into the drying cylinder. When the moisture content of the clothes is relatively high, the drying temperature can be increased to adopt high-temperature drying to promote rapid evaporation of moisture. When the moisture content of the clothes is relatively low, the drying temperature can be decreased to adopt low-temperature drying, which can avoid damaging the clothes due to high temperature and can also reduce the power of the dryer and energy consumption.

[0037] The fan speed is the speed of the fan in the above-mentioned drying equipment. When the moisture content of the clothes is relatively high, the fan speed can be increased to quickly vertically send the hot air into the drying cylinder, keep the temperature in the drying cylinder continuously in a hot state, and increase the air flow speed, which is beneficial to rapid drying. When the moisture content of the clothes is relatively low, the fan speed can be appropriately decreased, which is beneficial to reducing energy consumption.

[0038] The drying rotation speed is the rotation speed of the drying cylinder. When the moisture content of the clothes is relatively high, the drying rotation speed can be increased. On the one hand, the moisture in the clothes can be thrown out by centrifugal force, and it can also increase the contact area between the clothes and the hot air to accelerate the evaporation of moisture. When the moisture content of the clothes is relatively low, the drying rotation speed can be decreased to reduce energy consumption.

[0039] The drying time is the duration of the current drying mode, or it can also be the duration of the combination of the current drying temperature and the corresponding rotation speed. When the moisture content of the clothes is relatively high, a longer drying time needs to be set. When the moisture content of the clothes is relatively low, a shorter drying time can be set.

[0040] At least one of the above-mentioned drying temperature, drying time, fan speed, and drying rotation speed can be a fixed value, and the rest are variable values; or at least two are fixed values, and the rest are variable values, or all can be variable values.

[0041] For example: when the moisture content is relatively high, select the first drying mode and start the first drying equipment and the second drying equipment to perform the drying operation simultaneously. A relatively high drying temperature can be set only, or the fan speed can be increased simultaneously, or the drying rotation speed can be increased simultaneously. Of course, the drying time can also be extended simultaneously.

[0042] When the moisture content is relatively low, select the second drying mode or the third drying mode, and start the first drying equipment or the second drying equipment to perform the drying operation correspondingly. A relatively high drying temperature or a relatively low drying temperature can be set, or a relatively high fan speed or a relatively low fan speed can be adopted simultaneously, or a relatively high drying rotation speed or a relatively low drying rotation speed can be adopted simultaneously. Of course, the drying time can also be appropriately set, and it can be specifically set according to experience.

[0043] Step 104: Control the corresponding drying equipment to perform the drying operation according to the drying parameters.

[0044] After the above-mentioned drying parameters are set, the corresponding drying equipment can be started to perform the drying operation.

[0045] In the first drying mode, start the first drying device and the second drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0046] In the second drying mode, start the first drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0047] In the third drying mode, start the second drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0048] The technical solution provided by this embodiment first obtains the moisture content of the clothes; then determines the drying mode according to the moisture content of the clothes. The drying modes include: the first drying mode, the second drying mode, and the third drying mode; in the first drying mode, start the first drying device and the second drying device simultaneously to perform the drying operation; in the second drying mode, start the first drying device to perform the drying operation; in the third mode, start the second drying device to perform the drying operation; then determine the drying parameters according to the drying mode. The drying parameters include at least one of: drying temperature, drying time, fan speed, and drying speed; then control the corresponding drying device to perform the drying operation according to the drying parameters, realizing drying the clothes with different drying modes and different drying parameters according to the moisture content of the clothes, achieving the effect of improving the drying efficiency and reducing the energy consumption at the same time.

[0049] On the basis of the above technical solution, the first drying device specifically includes a heater and a first fan. The heater uses the principle of electric heating to heat the air in the drying channel, and the first fan is used to blow the heated hot air into the drying cylinder.

[0050] The second drying device includes a heat pump and a second fan. The heat pump generates heat through the principles of air compression condensation and evaporation to heat the air in the drying channel, and the second fan is used to blow the heated hot air into the drying cylinder. This embodiment uses a heat pump to heat the air, which can greatly reduce the energy consumption and thus reduce the cost.

[0051] In addition, this embodiment can select to work independently or cooperate with the heater and the heat pump according to the different moisture contents of the clothes, which can not only improve the drying rate and effect, but also reduce the energy consumption, and can also adapt to different drying conditions, with high flexibility and can meet the drying requirements of clothes with different moisture contents.

[0052] The hot air outlet of the above heating channel is communicated with the drying cylinder, and the implementation manner of the heating channel and its connection relationship with the drying cylinder can be realized by known technologies.

[0053] Further, during the drying operation, the moisture content of the clothes is obtained at a preset period, and the drying mode or drying parameters are adjusted according to the moisture content of the clothes. That is to say, during the execution of a certain drying mode, the drying parameters are not fixed and can also be adjusted according to the periodically detected moisture content.

[0054] For example: during the drying process using the first drying mode, if it is detected that the moisture content drops significantly within a short period of time, the drying time can be shortened, the drying speed can be reduced, or the drying temperature can be lowered. Of course, it is also possible to switch to the second drying mode or the third drying mode.

[0055] Performing periodic detection of the moisture content and adjusting the drying parameters in real time can further improve the drying flexibility, and timely adjust the drying temperature, speed or time according to the change of the moisture content, so as to achieve a better balance between drying efficiency and energy consumption, and avoid incomplete drying or over-drying.

[0056] Embodiment 2

[0057] Based on the above embodiment, this embodiment further provides a drying control method.

[0058] The drying control method provided in this embodiment includes:

[0059] Step 101: Obtain the moisture content of the clothes.

[0060] The moisture content of the clothes can be obtained in various ways. When the clothes are placed in the drying cylinder, the humidity inside the drying cylinder can be collected by a humidity sensor, and then the moisture content of the clothes can be obtained. It is also possible to obtain the moisture content of the clothes by weighing the drying cylinder.

[0061] Step 102: Determine the drying mode according to the moisture content of the clothes.

[0062] The drying modes include: the first drying mode, the second drying mode, and the third drying mode; in the first drying mode, the first drying device and the second drying device are simultaneously started to perform the drying operation; in the second drying mode, the first drying device is started to perform the drying operation; in the third mode, the second drying device is started to perform the drying operation.

[0063] The first drying device and the second drying device can be the same device or different devices. For example, both the first drying device and the second drying device can be heaters, or the first drying device is a heater and the second drying device is a heat pump. Both the heater and the heat pump are used to increase the temperature of the air in the drying channel to generate hot air. In addition, the first drying device and the second drying device also include a blower for blowing the hot air into the drying cylinder.

[0064] Step 103: Determine the drying parameters according to the drying mode.

[0065] The drying parameters include at least one of the drying temperature, drying time, blower speed, and drying cylinder speed.

[0066] After determining the drying mode and the drying device to be started, at least one of the drying temperature, drying time, blower speed, and drying cylinder speed can be set.

[0067] The drying temperature is the temperature of the hot air input into the drying cylinder. When the moisture content of the clothes is relatively high, the drying temperature can be increased and high-temperature drying can be adopted to promote the rapid evaporation of moisture. When the moisture content of the clothes is relatively low, the drying temperature can be decreased and low-temperature drying can be adopted to avoid damaging the clothes at high temperature and can also reduce the power consumption of the dryer and energy consumption.

[0068] The blower speed is the speed of the blower in each of the above drying devices. When the moisture content of the clothes is relatively high, the blower speed can be increased to quickly blow the hot air vertically into the drying cylinder, keep the temperature in the drying cylinder continuously hot, and increase the air flow speed, which is beneficial to rapid drying. When the moisture content of the clothes is relatively low, the blower speed can be appropriately decreased, which is beneficial to reducing energy consumption.

[0069] The drying cylinder speed is the speed of the drying cylinder. When the moisture content of the clothes is relatively high, the drying cylinder speed can be increased. On the one hand, the moisture in the clothes can be thrown out by centrifugal force, and on the other hand, the contact area between the clothes and the hot air can be increased to accelerate the evaporation of moisture. When the moisture content of the clothes is relatively low, the drying cylinder speed can be decreased to reduce energy consumption.

[0070] The drying time is the duration of the current drying mode, or can also be the duration of the combination of the current drying temperature and the corresponding speed. When the moisture content of the clothes is relatively high, a longer drying time needs to be set. When the moisture content of the clothes is relatively low, a shorter drying time can be set.

[0071] At least one of the above drying temperature, drying time, blower speed, and drying cylinder speed can be a fixed value, and the rest are variable values; or at least two are fixed values, and the rest are variable values, or all can be variable values.

[0072] Determine the drying mode according to the moisture content of the clothes. The moisture content can be compared with a preset threshold, divided into high moisture content, medium moisture content, low moisture content, etc., and the drying mode is determined according to different moisture contents. For example:

[0073] Judge whether the moisture content is greater than the first threshold; if the moisture content is greater than the first threshold, select the first drying mode, and at the same time start the first drying device and the second drying device to perform the drying operation. And set the first drying temperature of the first drying device to w1, the first fan speed to v1; the second drying temperature of the second drying device to w1, the second fan speed to v1; the drying speed to r1, and the running time to t1.

[0074] If the moisture content is less than or equal to the first threshold, then judge whether the moisture content is greater than the second threshold; if the moisture content is greater than the second threshold, select the second drying mode, start the first drying device to perform the drying operation, and set the first drying temperature of the first drying device to w2, the first fan speed to v2; the drying speed to r2, and the running time to t2.

[0075] If the moisture content is less than or equal to the second threshold, then judge whether the moisture content is greater than the third threshold; if the moisture content is greater than the third threshold, select the third drying mode, start the second drying device to perform the drying operation, and set the second drying temperature of the second drying device to w2, the second fan speed to v2; the drying speed to r1, and the running time to t1.

[0076] One implementation is: the above w1 is greater than w2, v1 is greater than v2, r1 is greater than r2, and t1 is greater than t2. It is equivalent to using high-temperature and high-speed drying when the moisture content is high, and low-temperature and low-speed drying when the moisture content is low.

[0077] If the moisture content is greater than the third threshold, after starting the second drying device to perform the drying operation, it further includes: selecting the fourth drying mode, starting the second drying device to perform the drying operation, and setting the second drying temperature of the second drying device to w3, the second fan speed to v3; the drying speed to r3, and the running time to t3.

[0078] One implementation is: the above w2 is greater than w3, v2 is greater than v3, r2 is greater than r3, and t2 is greater than t3. There are also two parameter setting combinations for the second drying device, corresponding to the third drying mode and the fourth drying mode respectively, to realize dynamic adjustment of the drying temperature and time according to the moisture content of the clothes.

[0079] Step 104, control the corresponding drying device to perform the drying operation according to the drying parameters.

[0080] After the above drying parameters are set, the corresponding drying device can be started to perform the drying operation.

[0081] In the first drying mode, start the first drying device and the second drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0082] In the second drying mode, start the first drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0083] In the third drying mode, start the second drying device to work, raise the drying temperature to the set value. Make the fan work at the set fan speed, make the drying cylinder rotate at the set drying speed, and continue for the set drying time.

[0084] In the above solution, determine the drying mode according to the moisture content of the clothes, make the first drying device and / or the second drying device perform the drying operation and determine at least one of the drying temperature, drying time, fan speed and drying speed, realizing drying the clothes with different drying modes and different drying parameters according to the moisture content of the clothes, achieving the effect of improving the drying efficiency and reducing the energy consumption at the same time.

[0085] The first drying device specifically includes a heater and a first fan. The heater uses the principle of electric heating to heat the air in the drying channel, and the first fan is used to blow the heated hot air into the drying cylinder.

[0086] The second drying device includes a heat pump and a second fan. The heat pump generates heat through the principles of air compression condensation and evaporation to heat the air in the drying channel, and the second fan is used to blow the heated hot air into the drying cylinder. In this embodiment, the heat pump is used to heat the air, which can greatly reduce the energy consumption and thus reduce the cost.

[0087] In addition, this embodiment can select to work independently or cooperate with the heater and the heat pump according to the different moisture content of the clothes, which can not only improve the drying rate and effect, but also reduce the energy consumption, and can also adapt to different drying conditions, with high flexibility and can meet the drying requirements of clothes with different moisture contents.

[0088] Further, during the drying operation, the moisture content of the clothes is obtained at preset intervals, and the drying mode or drying parameters are adjusted according to the moisture content of the clothes. That is to say, during the execution of a certain drying mode, the drying parameters are not fixed and can also be adjusted according to the periodically detected moisture content. For details, please refer to the above embodiments. The method of periodically detecting the moisture content and adjusting the drying parameters in real time can further improve the drying flexibility, and timely adjust the drying temperature, rotation speed or time according to the change of the moisture content, so as to achieve a better balance between drying efficiency and energy consumption, and avoid incomplete drying or over-drying.

[0089] Embodiment 3

[0090] As Figure 2 、 Figure 3 and Figure 4 shown, this embodiment optimizes the drying control method on the basis of the above embodiments:

[0091] Step 201: Obtain the moisture content of the clothes.

[0092] The moisture content of the clothes can be obtained in various ways. When the clothes are placed in the drying cylinder, the humidity in the drying cylinder can be collected by a humidity sensor, and then the moisture content of the clothes can be obtained. It is also possible to obtain the moisture content of the clothes by weighing the weight of the drying cylinder.

[0093] Step 202: Determine the drying mode according to the moisture content of the clothes.

[0094] The drying modes include: the first drying mode, the second drying mode and the third drying mode; in the first drying mode, the first drying device and the second drying device are simultaneously started to perform the drying operation; in the second drying mode, the first drying device is started to perform the drying operation; in the third mode, the second drying device is started to perform the drying operation.

[0095] The first drying device and the second drying device can be the same device or different devices. For example, both the first drying device and the second drying device can be heaters, or the first drying device is a heater and the second drying device is a heat pump. Both the heater and the heat pump are used to increase the temperature of the air in the drying channel and generate hot air. In addition, the first drying device and the second drying device also include a blower for blowing the hot air into the drying cylinder.

[0096] Determine the drying mode according to the moisture content of the clothes. For example, when the moisture content is high, select the first drying mode and simultaneously start the first drying device and the second drying device to perform the drying operation. When the moisture content is medium, the first drying device can be started. When the moisture content is low, the second drying device is started.

[0097] Step 203: Obtain the material information of the clothes.

[0098] In this step, a clothing image can be collected by an image recognition device, and clothing information can be determined based on the clothing image. A clothing information database is established in advance according to common clothing fabric types. An image acquisition device can be set inside the drying drum or on the outer surface of the dryer to collect the clothing image.

[0099] After obtaining the clothing image, features such as texture and gloss in the image are extracted and analyzed, and then compared with the data in the clothing information database to determine the clothing type, such as cotton, polyester fiber, wool, silk, etc.

[0100] Another way is to set a user operation device on the dryer, such as a touch screen, buttons, knobs, etc., and the user can input the clothing type through these devices. Then, the clothing material information can be obtained from the clothing information input by the user.

[0101] Furthermore, after determining the clothing information, it further includes: determining a drying temperature range according to the clothing information, and the drying temperature range includes a high-temperature range and a low-temperature range. For example: for clothing such as wool that is not resistant to high temperatures, when the clothing information is determined to be wool, the set drying temperature range is 0°C - 30°C, and the subsequent drying temperature cannot exceed this temperature range to avoid damaging the clothing by high-temperature drying. Cotton clothing is resistant to high temperatures, and the set drying temperature range is 0°C - 90°C.

[0102] Step 204: Determine the drying parameters according to the material information of the clothing and the drying mode.

[0103] The drying parameters include at least one of drying temperature, drying time, fan speed, and drying rotation speed.

[0104] Judge whether the moisture content is greater than the first threshold; if the moisture content is greater than the first threshold, select the first drying mode, and at the same time start the first drying device and the second drying device to perform the drying operation. And set the first drying temperature of the first drying device to w1 and the first fan speed to v1 according to the material information of the clothing; the second drying temperature of the second drying device is w1, and the second fan speed is v1; the drying rotation speed is r1, and the running time is t1. w1 needs to meet the requirements of the clothing drying temperature range.

[0105] If the moisture content is less than or equal to the first threshold, then judge whether the moisture content is greater than the second threshold; if the moisture content is greater than the second threshold, select the second drying mode, start the first drying device to perform the drying operation, and set the first drying temperature of the first drying device to w2 and the first fan speed to v2; the drying rotation speed is r2, and the running time is t2.

[0106] If the moisture content is less than or equal to the second threshold, then determine whether the moisture content is greater than the third threshold; if the moisture content is greater than the third threshold, select the third drying mode, start the second drying device to perform the drying operation, and set the second drying temperature of the second drying device to w2, the second fan speed to v2; the drying speed is r1, and the running time is t1. w2 needs to meet the requirements of the clothing drying temperature range.

[0107] One implementation is: the above w1 is greater than w2, v1 is greater than v2, r1 is greater than r2, and t1 is greater than t2. That is, when the moisture content is relatively high, high-temperature and high-speed drying is adopted, and when the moisture content is relatively low, low-temperature and low-speed drying is carried out.

[0108] If the moisture content is greater than the third threshold, after starting the second drying device to perform the drying operation, it further includes: select the fourth drying mode, start the second drying device to perform the drying operation, and set the second drying temperature of the second drying device to w3, the second fan speed to v3; the drying speed is r3, and the running time is t3. w3 needs to meet the requirements of the clothing drying temperature range.

[0109] One implementation is: the above w2 is greater than w3, v2 is greater than v3, r2 is greater than r3, and t2 is greater than t3. There are also two parameter setting combinations for the second drying device, corresponding to the third drying mode and the fourth drying mode respectively, to realize dynamic adjustment of the drying temperature and time according to the moisture content of the clothing.

[0110] As Figure 4 shown, another implementation is: after confirming the drying mode, determine whether the clothing material is a high-temperature material or a low-temperature material. For example: in the first drying mode, run the first drying device and the second drying device. When the clothing material is a clothing material suitable for high temperature, the first drying temperature is w1, the first fan speed is v1, the second drying temperature is w1, and the second fan speed is v1; the drying speed is r1, and the drying time is t1. When the clothing material is a clothing material suitable for low temperature, the first drying temperature is w2, the first fan speed is v2, the second drying temperature is w2, and the second fan speed is v2; the drying speed is r2, and the drying time is t2.

[0111] In the second drying mode, run the first drying device. When the clothing material is a clothing material suitable for high temperature, the first drying temperature is w3, the first fan speed is v3, the drying speed is r3, and the drying time is t3. When the clothing material is a clothing material suitable for low temperature, the first drying temperature is w4, the first fan speed is v4; the drying speed is r4, and the drying time is t4.

[0112] In the third drying mode, the second drying device is operated. When the clothing material is a clothing material suitable for high temperature, the second drying temperature is w3, the second fan speed is v3; the drying speed is r5, and the drying time is t5. When the clothing material is a clothing material suitable for low temperature, the second drying temperature is w4, the second fan speed is v4; the drying speed is r6, and the drying time is t6.

[0113] The magnitudes of the above values can be set according to experience and adjusted according to the moisture content detected in real time.

[0114] Step 205: Control the corresponding drying device to perform the drying operation according to the drying parameters.

[0115] After the above drying parameters are set, the corresponding drying device can be started to perform the drying operation.

[0116] In the first drying mode, the first drying device and the second drying device are started to work, and the drying temperature is raised to the set value. The fan operates at the set fan speed, the drying cylinder rotates at the set drying speed, and the set drying time is maintained.

[0117] In the second drying mode, the first drying device is started to work, and the drying temperature is raised to the set value. The fan operates at the set fan speed, the drying cylinder rotates at the set drying speed, and the set drying time is maintained.

[0118] In the third drying mode, the second drying device is started to work, and the drying temperature is raised to the set value. The fan operates at the set fan speed, the drying cylinder rotates at the set drying speed, and the set drying time is maintained.

[0119] In the above solution, the drying mode is determined according to the moisture content of the clothing, and the first drying device and / or the second drying device perform the drying operation. Combining the material information of the clothing, at least one of the drying temperature, drying time, fan speed, and drying speed is determined. Different drying modes are adopted according to the moisture content of the clothing, and different drying parameters are used to dry the clothing, achieving the effect of improving the drying efficiency while reducing energy consumption. Moreover, the drying temperature can be set according to the material of the clothing. Clothes that can withstand high temperatures can be dried at high temperatures, and clothes that cannot withstand high temperatures can be dried at low temperatures and the drying time can be extended or the drying speed can be increased.

[0120] The first drying device specifically includes a heater and a first fan. The heater uses the principle of electric heating to heat the air in the drying channel, and the first fan is used to blow the heated hot air into the drying cylinder.

[0121] The second drying device includes a heat pump and a second blower. The heat pump generates heat through the principles of air compression, condensation, and evaporation to heat the air in the drying channel, and the second blower is used to blow the heated hot air into the drying cylinder. In this embodiment, the heat pump is used to heat the air, which can significantly reduce energy consumption and thus reduce costs.

[0122] In addition, this embodiment can independently or cooperatively operate the heater and the heat pump according to the moisture content of the clothes. It can not only improve the drying rate and effect, but also reduce energy consumption, and can adapt to different drying conditions, with high flexibility, and can meet the drying requirements of clothes with different moisture contents.

[0123] Furthermore, during the drying operation, the moisture content of the clothes is obtained at a preset cycle, and the drying mode or drying parameters are adjusted according to the moisture content of the clothes. That is to say, during the execution of a certain drying mode, the drying parameters are not fixed, and can also be adjusted according to the periodically detected moisture content. Specifically, reference can be made to the above embodiments. The method of periodically detecting the moisture content and adjusting the drying parameters in real time can further improve the drying flexibility, and timely adjust the drying temperature, rotation speed or time according to the change of the moisture content, so as to achieve a better balance between drying efficiency and energy consumption, and avoid incomplete drying or over-drying.

[0124] The drying control method provided in the above embodiments can be implemented by a computer program, for example, application software, etc.; or, the method can also be implemented as a medium storing relevant computer programs, for example, USB flash drives, cloud disks, etc.; or, the method can also be implemented by an entity device integrated or installed with relevant computer programs, for example, chips, mobile intelligent devices, etc.
