The data interface 212 can be used for being plugged in the device to be projected, and then signal connection is established between the data interface 212 and the device to be projected, so that the device to be projected can transmit the projected screen data to the screen transmission module 112 through data receiving, the screen transmission module 112 wirelessly transmits the projected screen data to the device to be displayed, and the device to be displayed is displayed through rapid wireless screen transmission.
When the touch screen transmitter 110 is placed on the charging dock 120, the first power receiving module 114 of the touch screen transmitter 110 is electrically connected to the power transmitting module 122 of the charging dock 120, and the power transmitting module 122 can transmit the first electrical signal to the first power receiving module 114. The first power receiving module 114 is connected to the power storage module 118, and then the first power receiving module 114 can transmit the acquired first electrical signal to the power storage module 118, so as to charge the power storage module 118. The power storage module 118 is connected to the screen transmission module 112, and the power storage module 118 can supply power to the screen transmission module 112, so that the screen transmission module 112 executes power-on initialization and maintains the connection state of the whole computer. When a user needs to perform a screen transmission operation, the screen transmission transmitter 110 is taken out of the charging seat 120, the first power receiving module 114 is electrically disconnected from the power transmitting module 122, and at this time, the power storage module 118 continuously supplies power to the screen transmission module 112, so that the screen transmission module 112 maintains the connection state of the whole machine, the system is prevented from being powered off, and the screen transmission module 112 is prevented from being disconnected from the connection state of the whole machine; when a user establishes electrical connection between the second power receiving module 116 and the device to be projected, the power is supplied to the screen transmission module 112 through the device to be projected, and the power storage module 118 is charged at the same time, so that the electric energy of the power storage module 118 is prevented from being exhausted, and the screen transmission module 112 maintains the connection state of the whole machine; when the data interface 212 is in signal connection with the device to be projected, screen projection data transmitted by the device to be projected is received, and the screen projection data is transmitted to the screen transmission module 112, so that the screen transmission module 112 transmits the screen projection data to the device to be displayed, the corresponding screen projection data can be rapidly displayed by screen projection, and the processes of power-on initialization and complete machine connection operation of the screen transmission module 112 do not need to be waited, thereby greatly shortening the screen projection waiting time, realizing the screen projection effect of 'second drawing', and improving the screen projection efficiency.
When no power is put into the charging dock 120 and the charging dock 120 is in an on state, the touch screen transmitter 110 is in an on state, that is, the power transmitting module 122 on the charging dock 120 transmits the first electrical signal to the first power receiving module 114 on the touch screen transmitter 110, and the first power receiving module 114 transmits the acquired first electrical signal to the power storage module 118, so as to charge the power storage module 118. In addition, the power storage module 118 may supply power to the screen transmission module 112, so that the screen transmission module 112 is powered on and initialized, and performs a complete machine connection operation. After the screen transmission module 112 completes the connection operation of the whole machine, the screen transmission module 112 may be continuously powered on the basis of the power storage module 118, so that the screen transmission module 112 maintains the connection state of the whole machine. If the screen-transmitting transmitter 110 is placed in the charging dock 120 for charging under the condition of electric quantity, the electric power transmitting module 122 transmits a first electric signal to the first electric power receiving module 114, the first electric power receiving module 114 transmits the acquired first electric signal to the electric power storage module 118, so as to charge the electric power storage module 118, and meanwhile, the electric power storage module 118 continuously supplies power to the screen-transmitting module 112, so that the screen-transmitting module 112 maintains the connection state of the whole machine.
After the screen transmission transmitter 110 is taken out of the charging dock 120, the power transmission module 122 is disconnected from the first power receiving module 114, the power storage module 118 continuously supplies the stored electric energy to the screen transmission module 112, so that the screen transmission module 112 continuously maintains the connection state of the whole machine, until a user inserts the second power receiving module 116 of the screen transmission transmitter 110 into a device to be projected (such as a computer), the power storage module 118 is charged through the device to be projected, and meanwhile, power is supplied to the screen transmission module 112, so that the screen transmission module 112 continuously maintains the connection state of the whole machine. When the data interface 212 of the screen transmission transmitter 110 is inserted into the device to be projected, the screen transmission module 112 is initialized and in a complete machine connection state, so that the device to be projected can quickly transmit screen projection data to the screen transmission module 112, and the screen projection data is wirelessly transmitted to the device to be displayed through the screen transmission module 112, so that the screen projection data can be quickly displayed on the screen transmission module, that is, the screen projection effect of 'second-time drawing' is realized, the process of power-on initialization and complete machine connection operation of the screen transmission module 112 after the screen transmission transmitter 110 is plugged into the device to be projected is not required, the screen projection waiting time is greatly shortened, and the screen projection efficiency is improved.
The capacity of the power storage module 118 only needs to guarantee the duration of a preset time (for example, about 1 minute) (the capacity of the power storage module 118 is limited by the volume), and in a habit of use, the user can not spend too long time from taking the screen transmitter 110 to inserting the screen device (for example, a computer) to be projected, and only needs to guarantee that the screen transmitting module 112 has enough electricity to operate in the preset time, so that the screen transmitter 110 can be inserted into the screen device to be projected, and then the screen data can be rapidly displayed and projected, and the screen projecting effect of 'second drawing' can be realized.
It should be noted that, after the screen transmitter 110 is inserted into a device to be screened (such as a computer), the device to be screened supplies power to the screen module 112 and charges the power storage module 118; when the screen is projected by replacing the computer, the second chart after the screen is projected by replacing the computer is realized as long as the time for taking out the screen transmission emitter 110 does not exceed the preset time (such as about 1 minute). And if the time for taking out the screen projection transmitter exceeds the preset time, projecting the screen according to a traditional connection mode.
It should be noted that the term "acquiring" used herein may be that the first device actively issues a relevant instruction for acquiring information, and the second device issues relevant information when receiving the instruction. "fetch" may also be the first device actively sending the relevant information to the second device that needs the information (without sending a demand instruction). For example, the power transmitting module 122 may actively send the first electrical signal to the first power receiving module 114, so that the first power receiving module 114 acquires the first electrical signal; the power transmitting module 122 may also transmit the first electrical signal to the first power receiving module 114 according to the request instruction transmitted by the first power receiving module 114.
