All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The communication rate control method provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a communication rate control method according to an embodiment of the present application, where the method may include:
and 101, acquiring communication quality information between the electronic equipment and the functional module.
The communication rate control method can be executed by electronic equipment such as a mobile phone, a notebook computer, a computer and the like. The electronic equipment is provided with a functional module, and the electronic equipment and the functional module are in communication connection in a wired mode. Functional modules such as secure digital cards (Secure Digital Memory Card, SD) or external memory cards (TF) may be provided as memory cards in the electronic device. The specific type of the functional module may be set according to requirements, which is not limited in this embodiment.
In this embodiment, the electronic device and the functional module are connected by a wired connection manner, so as to establish a transmission path between the electronic device and the functional module, and establish a communication connection through the transmission path. As shown in fig. 2, fig. 2 is a schematic diagram of connection between an electronic device and a functional module according to an embodiment of the present application, a processor 201 (Central Processing Unit, CPU) is disposed on a motherboard in the electronic device, and a Board To Board (BTB) connector 202 for connecting the processor 201 is disposed on a sub-Board, and a flexible circuit Board (Flexible Printed Circuit Board, FPC) connector 204 for connecting a memory card 205 is disposed on the sub-Board. The BTB connector 202 is connected to the FPC connector 204 through the FPC connector 203, thereby realizing wired connection between the processor 201 and the memory card 204, i.e., wired connection between the electronic device and the memory card. Before the electronic device leaves the factory, hardware parameters of electronic components such as the processor 201, the BTB connector 202, the FPC connector 203, the FPC connector 204 and the like are fixed, and when the memory card is configured by the user, the hardware parameters of the memory card may not match with the hardware parameters of the electronic components in the electronic device, and the hardware parameters include parameters such as resistance, capacitance, inductance and the like. When the hardware parameters of the electronic component and the memory card are not matched, impedance mismatch between the electronic component and the memory card occurs during communication. Since the communication rate is related to the impedance, the higher the communication rate, the higher the error rate during data transmission in the case of impedance mismatch. The CPU may need to be repeated multiple times to write data to the memory card or not to write data to the memory card during the process of writing data to the memory card. Also, when the processor reads data from the memory card, it may be repeated a plurality of times to read data from the memory card, or it may be impossible to read data directly.
In the running process of the electronic equipment, the communication connection with the memory card is established in a wired mode, and the electronic equipment communicates with the memory card through the established communication connection. In the communication process, for the communication connection between the electronic device and the memory card, communication quality information can be acquired, and the communication quality is determined according to the communication quality information.
In one embodiment, the communication quality information includes at least one of a number of repeated requests and a number of transmission failures in the data transmission process. In combination with the above example, after establishing a communication connection with the memory card, the electronic device may acquire the number of repeated requests and the number of transmission failures, which may indicate the communication quality of the communication connection, in each writing/reading of data to/from the memory card. For example, when the communication quality information includes the number of transmission failures, in each process of writing data into the memory card, if response information returned by the memory card is not received within a preset transmission time period after the data is sent to the memory card for the first time, the electronic device determines that the memory card does not receive the data, and the number of transmission failures is 1. After the response information returned by the memory card is not received, the electronic device can send data to the memory card for the second time, and if the response information returned by the memory card is not received within the preset transmission time period, the second data transmission failure is determined, and the number of transmission failures is 2. And by analogy, the transmission failure times in the data writing process can be counted. After receiving the response information returned by the memory card, the electronic device determines that the data writing is successful, and ends the data transmission. When the response information returned by the memory card cannot be received, after the number of transmission failures reaches the preset end number, determining that the data writing fails, stopping sending the data to the memory card, and ending the data transmission.
For another example, when the communication quality information includes the number of repeated requests, the electronic device first sends a data request to the memory card in each process of reading data from the memory card, and if the data returned by the memory card is not received within a preset receiving period, determines that the data reading fails. After determining that the data reading fails, the electronic device may send a retransmission request for the current data request to the memory card, and if the data returned by the memory card is not received within the preset receiving period, it is determined that the number of repeated requests is 1. After the retransmission request is sent to the memory card, the data returned by the memory card is not received within the preset receiving time period, the retransmission request for the data request can be sent to the memory card again, and if the data returned by the memory card is not received within the preset receiving time period, the number of repeated requests is determined to be 2. And by analogy, the repeated request times in the data request process can be counted. After receiving the data returned by the memory card, the electronic device determines that the data reading is successful, and ends the data transmission. When the electronic device cannot receive the data returned by the memory card, the electronic device can stop sending the retransmission request to the memory card after the repeated request times reach the preset end times, determine that the data reading fails, and end the data transmission.
It should be noted that, when the electronic device counts the number of repeated requests and the number of data transmission failures, the statistics is the number of times in each data transmission process. When the electronic device and the memory card perform the next data transmission after the communication is finished, the repeated request times and the data transmission failure times can be counted again.
In practical applications, when there is a transmission failure in the communication connection and a retransmission request is sent, it is indicated that there is an abnormality in the communication connection, and when there is a large number of transmission failures and/or a large number of repeated requests, it is indicated that the communication quality is poor. Accordingly, the electronic device can determine the communication quality of the communication connection based on the number of transmission failures or the number of repeated requests.
In one embodiment, the electronic device may determine the communication quality in combination with the number of repeated requests and the number of transmission failures. In combination with the above example, if the data transmission process includes both a process of writing data into the memory card and a process of reading data from the memory card, the electronic device may count the number of repeated requests and the number of data transmission failures at the same time, and sum the number of repeated requests and the number of data transmission failures to obtain communication quality information that may represent communication quality.
In the embodiment of the application, the communication quality is determined according to the repeated request times and the transmission failure times, and the error rate in the data transmission process can be accurately described due to the repeated request times and the transmission failure times, so that the communication quality between the electronic equipment and the functional module can be accurately determined. In practical applications, the communication quality information may also be represented by other parameters in the communication connection, and the specific type of the communication quality information may be set according to requirements, which is not limited in this embodiment.
And 102, under the condition that the communication quality information accords with a target abnormality judgment condition in a plurality of abnormality judgment conditions, adjusting the communication rate between the electronic equipment and the functional module according to the target abnormality judgment condition, and re-entering the step of acquiring the communication quality information between the electronic equipment and the functional module until the communication between the electronic equipment and the functional module reaches the maximum transmission rate under the condition that the fault tolerance rate is met.
Wherein, the adjustment modes corresponding to different abnormality judgment conditions are different.
In one embodiment, a plurality of abnormality determination conditions may be set in advance, and when the communication quality information meets one of the abnormality determination conditions, it indicates that the communication quality between the electronic device and the functional module is poor. At this time, the communication rate between the electronic device and the functional module can be adjusted, and when the impedance of the electronic device and the impedance of the functional module are not matched, the error rate in the data transmission process can be reduced, so that the communication quality can be improved.
Optionally, the adjustment mode includes reducing the communication rate, and the speed reduction amplitudes corresponding to different abnormal judgment conditions are different; in the case where the communication quality information meets a target abnormality determination condition among the plurality of abnormality determination conditions, the step of adjusting the communication rate between the electronic device and the functional module in accordance with the target abnormality determination condition may be realized by:
and under the condition that the communication quality information accords with the target abnormality judgment condition, reducing the communication rate between the electronic equipment and the functional module according to the speed reduction amplitude corresponding to the target abnormality judgment condition.
Wherein the communication quality information includes at least one of the number of repeated requests and the number of transmission failures in the data transmission process.
In one embodiment, when the communication quality information includes the number of repeated requests, in a case where the communication quality information meets the target abnormality determination condition, the step of reducing the communication rate between the electronic device and the functional module according to the speed reduction range corresponding to the target abnormality determination condition may be implemented as follows:
and under the condition that the repeated request times reach a target repeated request times threshold value in a plurality of repeated request times threshold values, reducing the communication rate between the electronic equipment and the functional module according to the speed reduction amplitude corresponding to the target repeated request times threshold value.
In this embodiment, a plurality of abnormality determination conditions may be preset, and different abnormality determination conditions correspond to different communication qualities and deceleration amplitudes, respectively. In combination with the above example, when the communication quality information is the number of repeated requests, a plurality of thresholds of the number of repeated requests may be preset, each of the thresholds of the number of repeated requests is an abnormal judgment condition, and different thresholds of the number of repeated requests correspond to different communication quality and speed reduction amplitude respectively. For example, the preset repeat request count threshold may include 2 times, 3 times, 4 times, and 5 times, the count 2 corresponds to a 5% deceleration, the count 3 corresponds to a 10% deceleration, the count 4 corresponds to a 15% deceleration, and the count 5 corresponds to a 20% deceleration. The larger the threshold number of repeated requests is, the worse the communication quality is. When the electronic device obtains the number of repeated requests 3 in the data transmission process, the number of repeated requests 3 which is the same as the number of repeated requests obtained at the time, namely the target abnormality judgment condition, can be determined from a plurality of preset repeated request number thresholds. At this time, the electronic device may determine the deceleration amplitude 15% corresponding to the repetition request number threshold 3, and if the current communication rate of the electronic device is 100MHz, the electronic device may adjust the communication rate to 85MHz. Meanwhile, the electronic equipment can instruct the memory card to adjust the communication rate from 100MHz to 85MHz, so that the communication rate of the memory card is equal to the communication rate of the electronic equipment after being reduced. The specific deceleration process may be set according to requirements, which is not limited in this embodiment.
In the embodiment of the application, when the communication quality information acquired by the electronic device meets the abnormal judgment condition, it can be determined that the current communication quality is poor, and the electronic device can reduce the communication rate between the electronic device and the storage module. At this time, since the communication rate in the communication connection is lowered, the number of errors in the data transmission process can be reduced, thereby improving the communication quality.
In practical application, the abnormal judgment conditions corresponding to different communication qualities can be set, and different speed reduction ranges are set for different communication qualities, so that the electronic equipment can reduce corresponding communication rate according to different abnormal judgment conditions, can realize gradual adjustment of the communication rate, and avoid reducing the communication rate to a minimum value at one time, thereby enabling the electronic equipment to communicate with the functional module at the highest possible communication rate.
In one embodiment, when the communication quality information includes the number of transmission failures, in a case where the communication quality information meets the target abnormality determination condition, the step of reducing the communication rate between the electronic device and the functional module according to the speed reduction range corresponding to the target abnormality determination condition may be implemented as follows:
And under the condition that the transmission failure times reach a target transmission failure times threshold value in a plurality of transmission failure times threshold values, reducing the communication rate between the electronic equipment and the functional module according to the speed reduction amplitude corresponding to the target transmission failure times threshold value.
In this embodiment, when the communication quality information is the number of transmission failures, a plurality of transmission failure frequency thresholds may be preset, each transmission failure frequency threshold is an abnormal judgment condition, and different transmission failure frequency thresholds respectively correspond to different communication quality and speed reduction amplitude. For example, the preset threshold number of transmission failures may include 2 times, 3 times, 4 times, and 5 times, the number of times 2 corresponds to 5% of the deceleration, the number of times 3 corresponds to 10% of the deceleration, the number of times 4 corresponds to 15% of the deceleration, and the number of times 5 corresponds to 20%. The larger the transmission failure number threshold value, the worse the communication quality. When the electronic device obtains the transmission failure frequency 3 in the data transmission process, the transmission failure frequency threshold 3 which is the same as the obtained transmission failure frequency can be determined from a plurality of preset transmission failure frequency thresholds, namely the target abnormality judgment condition. At this time, the electronic device may determine the deceleration amplitude corresponding to the transmission failure frequency threshold 3 by 15%, and if the current communication rate of the electronic device is 100MHz, the electronic device may adjust the communication rate to 85MHz. Meanwhile, the electronic equipment can instruct the memory card to adjust the communication rate from 100MHz to 85MHz, so that the communication rate of the memory card is equal to the communication rate of the electronic equipment after being reduced.
In another embodiment, the communication quality information may include both the number of repeated requests and the number of transmission failures. A plurality of frequency thresholds can be preset, each frequency threshold is an abnormal judgment condition, and different frequency thresholds respectively correspond to different communication quality and speed reduction amplitude. For example, the preset number of times threshold may include 2 times, 3 times, 4 times, and 5 times, the number of times 2 corresponds to 5% of the deceleration, the number of times 3 corresponds to 10% of the deceleration, the number of times 4 corresponds to 15% of the deceleration, and the number of times 5 corresponds to 20%. The larger the number of times threshold value, the worse the communication quality. When the sum of the transmission failure times and the repeated request times in the data transmission process is 3, the electronic equipment can determine the time threshold 3, namely the target abnormality judgment condition, from a plurality of preset time thresholds. At this time, the electronic device may determine the deceleration amplitude corresponding to the frequency threshold 3 by 15%, and when the current communication rate of the electronic device is 100MHz, the electronic device may adjust the communication rate to 85MHz. Meanwhile, the electronic equipment can instruct the memory card to adjust the communication rate from 100MHz to 85MHz, so that the communication rate of the memory card is equal to the communication rate of the electronic equipment after being reduced.
In the embodiment of the application, the communication quality is determined according to at least one parameter of the repeated request times and the transmission failure times, and the error rate in the output transmission process can be accurately described due to the repeated request times and the transmission failure times, so that the communication quality between the electronic equipment and the functional module can be accurately determined. The target parameter may also include other parameters in the communication connection, which is not limited in this embodiment.
In this embodiment, after the communication rate between the electronic device and the functional module is adjusted, the electronic device may re-execute step 101 and step 102 until the communication connection between the electronic device and the functional module can meet the fault tolerance rate, and stop executing step 101 and step 102 when the maximum transmission rate is reached. For example, the fault tolerance may include at least one of a number of repeated requests and a number of transmission failures. In combination with the above example, the fault tolerance may be 1 time, and when the electronic device and the storage device may communicate with each other, the number of repeated requests is 1 time or less, or the number of transmission failures is 1 time or less, or the sum of the number of repeated requests and the number of transmission failures is 1 time or less, in each data writing or reading process, it is determined that the communication connection satisfies the fault tolerance. When the fault tolerance is satisfied, the electronic device and the functional module are caused to communicate at the maximum transmission rate, and at this time, the execution of steps 101 and 102 is stopped.
It should be noted that, in the process of adjusting the communication rate between the electronic device and the functional module, the electronic device may also increase the communication rate between the electronic device and the functional module. Methods of adjusting the communication rate between the electronic device and the functional module may include, but are not limited to, the methods described in the examples above.
In summary, in this embodiment, a function module is provided on an electronic device, the electronic device and the function module establish a communication connection in a wired manner, obtain communication quality information between the electronic device and the function module, adjust a communication rate between the electronic device and the function module according to a target abnormality determination condition when the communication quality information meets the target abnormality determination condition of a plurality of abnormality determination conditions, and reenter a step of obtaining the communication quality information between the electronic device and the function module until the communication between the electronic device and the function module reaches a maximum transmission rate when the fault tolerance is satisfied. In the communication connection between the electronic equipment and the functional module, when the hardware parameters of the electronic equipment and the functional module are not matched, the error rate in the data transmission process can be reduced and the communication quality can be improved by adjusting the communication rate between the electronic equipment and the functional module.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of another communication rate control method according to an embodiment of the present application, where the method may include:
step 301, determining a third target communication protocol with the highest communication rate from a plurality of communication protocols supported by the electronic device and the functional module.
Step 302, establishing a communication connection based on the highest communication rate supported by the third target communication protocol.
In one embodiment, the electronic device and the functional module may each support multiple communication protocols, and when the communication connection is first established, the electronic device may first determine a third target communication protocol having a highest communication rate, and then establish the communication connection with the functional module based on the highest communication rate supported by the third target communication protocol.
In combination with the above example, the memory card may be a TF card, and the electronic device and the memory card may support SDR (Single Date Rate) protocol, SDR50 protocol and SD8.0 protocol, where the SD8.0 protocol has a communication rate higher than the SDR104 protocol, and the SDR104 protocol has a communication rate higher than the SDR50 protocol. The user may set the SD8.0 protocol to have a higher priority than the SDR104 protocol, and the SDR104 protocol to have a higher priority than the SDR50 protocol, according to the communication rate of each communication protocol. When the communication connection with the functional module is established for the first time, the electronic device can firstly determine that the SD8.0 protocol with the highest communication rate is the third target communication protocol according to the order of the priority from big to small, then send a request to the TF to determine whether the TF card supports the SD8.0 protocol, after receiving the response information which is sent by the TF card and supports the SD8.0 protocol, the electronic device can acquire the preset highest communication rate supported by the SD8.0 protocol, and establish the communication connection with the TF card at the highest communication rate supported by the SD8.0 protocol. If the TF card does not support the SD8.0 protocol, the electronic device can select and determine the SDR104 protocol from the SDR104 protocol and the SDR50 protocol according to the priority order, and establish communication connection with the TF card through the highest communication protocol supported by the SDR104 protocol. The specific process of establishing the communication connection may be set according to requirements, which is not limited in this embodiment.
In practical application, when the electronic device and the functional module support multiple communication protocols, the electronic device can establish communication connection with the functional module according to the highest communication rate supported by the communication protocol with the highest communication rate when the communication connection with the functional module is initially established, so that the electronic device and the functional module can communicate at the highest communication rate when the communication connection is initially established. When the communication quality between the electronic equipment and the functional module is poor and the communication rate is reduced, the communication rate can be adjusted on the basis of the highest communication rate, so that the communication between the electronic equipment and the functional module can be performed at the highest possible communication rate while the communication quality is ensured.
Step 303, obtaining communication quality information between the electronic device and the functional module.
And step 304, when the communication quality information accords with the target abnormality judgment condition in the plurality of abnormality judgment conditions, the communication rate between the electronic equipment and the functional module is adjusted according to the target abnormality judgment condition, and the step of obtaining the communication quality information between the electronic equipment and the functional module is re-entered until the maximum transmission rate is reached under the condition that the communication between the electronic equipment and the functional module meets the fault tolerance rate.
Optionally, the method may further include:
determining a first target communication protocol with a communication rate lower than the current communication protocol under the condition that the reduced communication rate is lower than the lower rate limit of the current communication protocol;
based on the first target communication protocol, a communication connection between the electronic device and the functional module is reestablished.
In one embodiment, when the reduced communication rate is below a lower rate limit corresponding to the current communication protocol, the electronic device may reestablish a communication connection with the functional module using a communication protocol having a relatively low communication rate. In combination with the above example, if the current communication protocol of the electronic device is the SD8.0 protocol, after the electronic device reduces the communication rate, if the reduced communication rate is less than the lower rate limit of the SD8.0 protocol, the electronic device may select one of the SDR104 protocol and the SDR50 protocol as the first target communication protocol, and reestablish the communication connection with the TF card based on the first target communication protocol. The lower rate limit of the communication protocol may be the lowest communication rate supported by the communication protocol, or may be a communication rate determined by the user according to actual requirements from the range of communication rates supported by the communication protocol, and the specific setting method of the lower rate limit may be set according to requirements, which is not limited in this embodiment.
In practical applications, different communication protocols correspond to different communication rate ranges, and when the communication rate of the electronic device is lower than the lower rate limit of the current communication protocol, the communication rate cannot be increased by using the current communication protocol, and the electronic device may not normally communicate.
In this embodiment, when the reduced communication rate is lower than the lower rate limit of the current communication protocol, the communication connection between the electronic device and the functional module is reestablished according to the communication protocol with the lower communication rate, so that normal communication between the electronic device and the functional module can be ensured, and when the communication quality is further reduced, the communication rate is reduced again, so that the communication rate is convenient to adjust.
In one embodiment, if the electronic device includes a plurality of communication protocols in addition to the current communication protocol, among all communication protocols supported by the electronic device and the functional module, the electronic device may select a communication protocol with a highest communication rate from the plurality of communication protocols as the first target communication protocol. In combination with the above example, when the reduced communication rate is lower than the lower rate limit of the SD8.0 protocol, the electronic device may select, according to the priority order, the SDR104 protocol with a high communication rate from the SDR104 protocol and the SDR50 protocol as the first target communication protocol, and reestablish the communication connection with the memory card according to the SDR104 protocol. In the process of selecting the first target communication protocol, the electronic equipment selects the communication protocol with high communication rate, so that the electronic equipment and the functional module can communicate with each other with the highest communication rate.
In another embodiment, when the electronic device reestablishes a communication connection with the functional module based on the first target communication protocol, the communication connection with the functional module may be established based on a highest communication rate supported by the first target communication protocol.
In summary, in this embodiment, a function module is provided on an electronic device, the electronic device and the function module establish a communication connection in a wired manner, obtain communication quality information between the electronic device and the function module, adjust a communication rate between the electronic device and the function module according to a target abnormality determination condition when the communication quality information meets the target abnormality determination condition of a plurality of abnormality determination conditions, and reenter a step of obtaining the communication quality information between the electronic device and the function module until the communication between the electronic device and the function module reaches a maximum transmission rate when the fault tolerance is satisfied. In the communication connection between the electronic equipment and the functional module, when the hardware parameters of the electronic equipment and the functional module are not matched, the error rate in the data transmission process can be reduced and the communication quality can be improved by adjusting the communication rate between the electronic equipment and the functional module.
Optionally, after acquiring the communication quality information between the electronic device and the functional module, the method may further include:
under the condition that the communication quality information accords with the communication failure condition, determining a second target communication protocol with a communication rate lower than the current communication protocol;
and reestablishing the communication connection between the electronic equipment and the functional module based on the second target communication protocol.
In one embodiment, the non-communication condition indicates that the communication quality between the electronic device and the functional module is poor, and the electronic device and the functional module cannot normally communicate. The electronic device can determine that the current communication protocol is not matched with the functional module under the condition of poor communication quality, and can directly switch the communication protocol. In combination with the above examples, the user may preset a communication failure condition, where the communication failure condition corresponds to a communication condition where communication quality is poor and normal communication is not possible. For example, the communication disabled condition may be set to 10 times, when the number of repeated requests is 10 times or more, the electronic device needs to retransmit the data request for a plurality of times to read the data from the memory card, and when the number of transmission failures is 10 times or more, the electronic device needs to perform a plurality of write operations to write the data into the memory card, and the communication rate cannot meet the normal communication requirement. At this time, the electronic device may directly select, according to the priority of the communication protocol, the SDR104 protocol with a higher communication rate from the SDR104 protocol and the SDR50 protocol as the second target communication protocol, and reestablish the communication connection between the electronic device and the functional module based on the SDR104 protocol. The specific type and parameter values of the non-communication condition may be set according to the requirements, and the present embodiment is not limited thereto.
In practical application, when the communication quality information is very poor and normal communication is impossible, the electronic device can directly switch the communication protocol and reestablish the communication connection. The method can avoid the adjustment process of the communication rate, rapidly switch the communication protocol, and communicate with the functional module by using the communication protocol with lower communication rate, thereby rapidly stabilizing the communication connection between the electronic equipment and the functional module.
