[0020] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should be within the scope of protection of the present application.

[0021] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0022] For short-distance wired state, when data communication is carried out between two devices, the data processing capacity (speed) of the data receiving end device is limited, and the data sending end device needs to adaptively adjust its data sending rate, so that the data receiving device can correctly receive data, and the problem of data loss at the receiving device due to insufficient processing time can be avoided, thereby improving the data transmission reliability. The application range is directed to short-distance wired and slow data transmission scenarios. However, in the prior art, the method capable of controlling the data transmission rate relies on network transmission protocols and related network devices, which has high cost and complex method.

[0023] As shown in Figure 1 The present application embodiment provides a kind of self-adaptive method of wired data transmission rate, applied to a kind of wired data transmission system, the limited data transmission system includes data sending device and data receiving device, including preparation phase and dynamic adjustment phase, wherein, the dynamic adjustment phase includes:

[0024] S1 controls data sending device to send multiple data frames to data receiving device;

[0025] S2 determines the difference duration of the duration used for data processing and the duration used for data sending of each frame of data;

[0026] S3 sets the maximum difference duration in the continuous n data frames as the first calibration difference duration, wherein n≥2, n is a natural number;

[0027] S4 controls the data sending device to send the first data frame after the n continuous data frames to the data receiving device after delaying for the first calibration difference time length, and sends the second data frame after the n continuous data frames.

[0028] Specifically, in the dynamic adjustment stage, the maximum difference time length in the n continuous data frames is set as the first calibration difference time length, and the data sending device is controlled to send the n-th data frame in the n continuous data frames to the data receiving device after delaying for the first calibration difference time length, that is, the time difference between each data frame and the sending time of the previous data frame is the difference time length of the data processing time length and the data sending time length of the maximum one of the n data frames before this data frame. This way makes the frequency of the data sending device sending data frames dynamic, which can adaptively adjust the frequency; at the same time, it does not rely on the network transmission protocol and related network devices, and reduces the cost while realizing the adaptive adjustment of the data sending frequency.

[0029] It should be noted that the present application does not limit the specific value of n, which can be selected according to the actual situation. For example, n=10 can be selected.

[0030] Optionally, the preparation stage comprises: controlling the data sending device to start sending data frames to the data receiving device; controlling the data receiving device to send a signal representing the end of data frame processing to the data sending device after the current data frame processing is completed; when the data sending device receives the signal representing the end of data frame processing, controlling the data sending device to send the next data frame to the data receiving device until the n-th data frame is sent.

[0031] Specifically, it is easy to understand that before sending the n+1-th data frame, the difference time length of the data processing time length and the data sending time length of the n data frames is not available for reference, therefore, the sending of the first n data frames is set as the preparation stage, at this time, when the data sending device receives the signal representing the end of data frame processing, the data sending device is controlled to send the next data frame to the data receiving device until the n-th data frame is sent.

[0032] Optionally, the preparation stage further comprises: obtaining the data processing time length and the data sending time length of each data frame; determining the difference of the data processing time length and the data sending time length of each data frame; setting the maximum difference time length in the first-n data frames as the second calibration difference time length.

[0033] It can be understood that after the n+1th data frame is sent, the n+2th data frame is sent after the second calibration difference value interval.

[0034] Optionally, the dynamic adjustment stage further comprises: judging whether the signal sending time for starting processing of the current data frame is later than the signal sending time for ending processing of the previous data frame; if the signal sending time for starting processing of the current data frame is not later than the signal sending time for ending processing of the previous data frame, controlling the data sending device to resend the current data frame.

[0035] It needs to be understood that if the signal sending time for starting processing of the current data frame is not later than the signal sending time for ending processing of the previous data frame, it can be considered that the current data frame fails to be sent, and at this time, the data sending device needs to be controlled to resend the current data frame.

[0036] Optionally, the dynamic adjustment stage further comprises: if the signal sending time for starting processing of the current data frame is later than the signal sending time for ending processing of the previous data frame, determining the delay time length of the signal sending time for starting processing of the current data frame being later than the signal sending time for ending processing of the previous data frame; judging whether the delay time length is greater than a preset maximum delay time length; if the delay time length is greater than the preset maximum delay time length, decreasing the value of n.

[0037] Specifically, if the signal sending time for starting processing of the current data frame is later than the signal sending time for ending processing of the previous data frame, it indicates that the maximum difference value time length of the previous n data frames and the difference value time length of the current data frame exist deviation, and the delay time length of the signal sending time for starting processing of the current data frame being later than the signal sending time for ending processing of the previous data frame is further determined, and if the delay time length is greater than the preset maximum delay time length, it indicates that the deviation of the maximum difference value time length of the previous n data frames and the difference value time length of the current data frame is large, and at this time, the deviation can be reduced by decreasing the value of n.

[0038] Optionally, the dynamic adjustment stage further comprises: judging whether the delay time length is less than a preset minimum delay time length; if the delay time length is less than the preset minimum delay time length, increasing the value of n.

[0039] Similarly, if the delay time length is less than the preset minimum delay time length, it indicates that the deviation of the maximum difference value time length of the previous n data frames and the difference value time length of the current data frame is small, and on this basis, in order to balance the processing amount of the data frame sending frequency, the value of n can be appropriately increased, which can reduce the processing amount of the data transmission system on the data frame sending frequency.

[0040] It should be understood that the preset maximum delay duration and the minimum delay duration can be selected according to factors such as data frame processing amount, which is not limited in the present application.

[0041] According to another aspect of the embodiments of the present application, a wired data transmission system is further provided, which comprises a data sending device and a data receiving device, and a first signal line, a second signal line and a data line are connected between the data sending device and the data receiving device.

[0042] Specifically, the data line is responsible for data transmission between the two devices; the first signal line is responsible for informing the data sending device of the time when the data receiving device starts to receive and process data; and the second signal line is responsible for informing the data sending device of the time when the data receiving device ends to receive and process data. Optionally, the data frame length transmitted between the first signal line and the second signal line is equal each time.
