Embodiment Construction
[0018] Please also refer to figure 1 and figure 2 , the synchronous control system 1 includes a plurality of electronic devices 10, and these electronic devices 10 are connected by wire or wirelessly and communicate according to a preset communication protocol. In this embodiment, each electronic device 10 is provided with two modes for the user to choose, that is, the master mode and the slave mode. When the electronic device 10 enters the master mode, the electronic device 10 is the master device 100, and other electronic devices 10 are the slave devices 200, and only one electronic device 10 can be set as the master device 100 at the same time, at least one The electronic device 10 is set as the slave device 200 . The user's operation information on the master device 100 can be transmitted to each slave device 200 to control the slave device 200 to perform the same operation as the master device 100 .
[0019] In this embodiment, the synchronous control system 1 may be ...

The invention relates to an electronic control device which comprises a keystroke input unit, a communication unit, a storage unit and a keystroke sequence module, wherein the keystroke input unit comprises at least one key-press with a unique keystroke code; the storage unit is used for storing a keystroke code list corresponding to every keystroke; the keystroke sequence module is used for executing the function corresponding to the keystroke or combination, and obtaining the keystroke code of the keystroke or combination from the keystroke code list; and the keystroke sequence module sends the keystroke code to the other devices so as to control the other devices to execute the function corresponding to the keystroke or combination. The invention also provides a synchronous control method. According to the invention, the keystroke code of the operated keystroke of electronic equipment is send to the other devices to control the other devices to execute the corresponding keystroke function according to the keystroke corresponding to the keystroke code.
Description
technical field [0001] The invention relates to an electronic device used in a synchronous control system and a synchronous control method thereof. Background technique [0002] Existing synchronous control systems such as synchronous teaching or conference systems usually include a master device and multiple slave devices connected to the master device. The master device and the slave device are usually computers provided with keys or touch input devices, and a display screen. During the process of synchronous teaching or conference, the teaching or conference system transmits the operation information of the master device to each slave device as an execution script, and at the same time displays the operation screen of the master device synchronously on the display screens of each slave device. However, the execution script takes up more memory when running, so each slave device cannot always keep in sync with the master device, and each slave device cannot re-check the p...
