Method for realizing synchronous data communication among multiple entertainment devices

[0023]Example one:

[0024]Such asFigure 1-2As shown, the embodiment of the present invention provides a method for realizing synchronous data communication between multiple entertainment devices, including a data transmission structure set in the entertainment device and a data transmission structure set on at least one control terminal, the data transmission structure including data receiving And the data sending end, the channel transmission of the data obeys the BSC protocol to perform synchronous data communication between the entertainment equipment and the control terminal. There are two sets of communication channels between the two data transmission structures, each set of the communication channels A data circulator is arranged on and close to the transmitting end, the data circulator is also provided with a controller that controls whether data is cyclically transmitted or enters a communication channel, and the data circulator also includes a timer that controls the start of data transmission. A control unit for controlling synchronization of the timer is provided on the timer.

[0025]The two sets of communication channels between the two data transmission structures transmit information in opposite directions. The data transmission speed in the data circulator is the same as the data transmission speed in the communication channel. Set the data circulator, set the cycle number of one group to 2, and set the cycle number of the other group to 3. Through the difference between the two groups of cycle numbers, the two sets of data can be adjusted synchronously, for example, the cycle number is set to 2 is slower than the time of 5 data transmission units with the number of cycles set to 3, then synchronous data transmission can be realized at the time of the 9th data transmission unit, that is, the time difference between 3×3 and 2×2 is 5. The data circulator is set as a finite unit, and the number of cycles is in units of bits or bytes. During the transmission of the data circulator, every time it circulates, it always sends an "inquiry command to the control unit synchronized with the timer through the communication channel" ", after each cycle, an inquiry command is issued, whether it can pass through the communication channel, the entertainment equipment is provided with several, each of the entertainment equipment is equipped with a data transmission structure, any two of the entertainment equipment Two sets of communication channels are provided between the data transmission structures, the data circulator is also provided with a plurality of data storage units, the data transmission between the data sending end and the data circulator is wired transmission, and the data circulator The data transmission mode with the data receiving end is wired or wireless transmission.
