In the embodiment of the present invention, the first preset value may be an average duration of device access switching; when the interface level is detected to be switched from low to high and the duration time reaches the average time length of the equipment access switching, the system judges the wired equipment accessed to the rising edge access mode.
In step S304, it is determined that the system accesses a falling edge access mode wired device when detecting that the interface level is switched from high to low and the duration time satisfies a second preset value.
In the embodiment of the present invention, the second preset value may be an average duration of device access switching; when the interface level is detected to be switched from high to low and the duration time reaches the average duration of the access switching of the equipment, the system judges that the wired equipment in the falling edge access mode is accessed. The first preset value and the second preset value may be the same or different.
In step S306, the analog-to-digital converter determines that the system accesses a multi-pin access mode wired device when it detects that the multi-pin interface level is switched from high to low and the duration time satisfies a third preset value.

Or,
| frame2i-frame2i-1| > delta or | frame2i-frame2i+1Deletion of frame for | > delta2i;
Wherein the frame is2i+1、frame2i-1Being digital representations of odd frames, frames2i、frame2(i+1)The numerical expression of the even frame, and δ is a set threshold.
In the embodiment of the invention, odd frames are taken as an example, the odd frames are acquired in real time according to the transmission sequence, the difference between each acquired odd frame and the previous even frame or the next even frame is calculated, when the difference is less than 10%, the difference between the previous frame and the next even frame is considered to be small by a system, and the omission of the odd frames has no obvious influence on the displayed content, so the odd frames can be deleted to reduce the transmitted data amount. Furthermore, as another optional implementation manner, after the current frame is deleted, the difference operation is performed on the next frame and the previous frame of the current frame, so that the connection deletion of the frames of the static picture can be implemented, and the problem of transmitting a large amount of data in the static picture can be avoided by this manner. In the embodiment of the present invention, optionally, the difference value may be calculated by calculating a difference between values of the pixels of the two frames before the calculation, for example, when the percentage of the corresponding pixel whose difference value is not 0 to all the pixels is less than 10%, it may be determined that the difference between the two frames is small.
Step S404, when the transmission mode is the control command mode:
and respectively acquiring the codes of two adjacent control commands, subtracting the codes of the two adjacent control commands, and deleting the next control command if the difference value is 0.
In the embodiment of the present invention, the control command may be encoded by ascii or unicode. Whether the two control commands are the same or not can be judged by subtracting the codes of the control commands, if the front control command and the rear control command are the same, the system judges that the display content of the equipment is not changed, and at the moment, the effect of reducing the data transmission quantity can be achieved by deleting the repeated same commands.

It should be noted that the process may be measured in a time unit, for example, for the previous minute, the deleted display frame accounts for 15% of the total display frames in the time period, and then the idle rate of the bus in the time period is 15%, and the unit time may be further extended, so as to obtain an average space rate; in the invention, the idle ratio is dynamic and can be changed according to the specific situation of data transmission.
And step S504, determining the idle ratio of the IIC bus according to the percentage of the deleted control commands in the unit time to the total data volume.
In the embodiment of the present invention, the IIC bus is generally used for data transmission in the control command mode, and the duty ratio of the deleted control commands can be determined according to the number of the deleted control commands, so as to obtain the idle duty ratio of the bus. For the description of the dynamic procedure of the idle duty ratio, refer to the description of the previous step.
And S506, sequencing the SPI bus, the RS485 bus and the IIC bus from large to small according to the idle ratio.

In the embodiment of the invention, the average value of the number of wired devices in the scene is obtained by counting the average number of the devices in the working state in the scene, so that the number change condition of the devices in the working state in the same scene at different times can be weighed. If the wired equipment in the working state is larger than the average value of the number of the wired equipment in the scene, the data volume transmitted by the cloud is large, the data volume between the cloud and the control center is large, and the transmitted data volume can be reduced by reducing the frame rate of the video data, so that a plurality of terminal equipment can work more stably.
