Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.
As shown in Figure 1, the hand-written touch pad of portable wireless keyboard described in the utility model comprises hand-held transmitter 1, and the receiver 2 that is connected with controlled computer, and the radio frequency signal by 2.4GHz between described transmitter 1 and the receiver 2 carries out communication.During use, transmitter 1 sends confirmation code with receiver 2 mutually by radio frequency signal and sets up man-to-man the connection, avoids producing between many transmitters and the receiver signal and disturbs.Being that transmitter has a process to sign indicating number with receiver when beginning to be connected, is to allow transmitter and receiver partner to the effect of sign indicating number, severally, can not disturb each other behind a pair of sign indicating number during in the work of same place equipment when having simultaneously.In to the sign indicating number process, both-way communication between receiver and the transmitter.
Wherein, described transmitter 1 comprises first radio-frequency (RF) transceiver 10, microcontroller 20, the keyboard 21 that is connected with microcontroller 20, hand-written touch pad 22 and laser pen 60 (can luminously indicating when demonstration), the input signal of keyboard 21 and hand-written touch pad 22 is launched to receiver 2 by first radio-frequency (RF) transceiver 10 after microcontroller 20 is handled.In addition, transmitter 1 also comprises feed circuit 30 (comprising battery 31 and charging circuit 32), and these feed circuit are connected with first radio-frequency (RF) transceiver 10, microcontroller 20, laser pen 60 respectively, and it is powered.
Described receiver 2 comprises second radio-frequency (RF) transceiver 40, the USB controller 50 that is connected with second radio-frequency (RF) transceiver 40, and the USB interface 51 that is connected with computing machine, after this receiver 2 receives signal from transmitter 1, be delivered to computing machine by USB controller 50, computing machine is carried out control operation.Receiver 2 is connected with computing machine by USB interface 51, and powers to receiver by computing machine.
Described keyboard 21 comprises I/O matrix keyboard and left and right operating key, and described hand-written touch pad 22 is a capacitive sensing touch panel, can be used as simultaneously touching mouse and handwriting pad, realizes the function of wireless handwriting input.Keyboard 21, hand-written touch pad 22 and first radio-frequency (RF) transceiver 10, microcontroller 20, feed circuit 30, laser pen 60 are as integral structure.When producing shift action on generation actuation of keys or the hand-written touch pad 22 on the keyboard 21, microcontroller 20 in the transmitter 1 can generate corresponding button or movable signal, and be sent to second radio-frequency (RF) transceiver 40 in the receiver 2 by first radio-frequency (RF) transceiver 10, send this signal to computing machine by USB controller 50 again, realize the control corresponding operation.
