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, portable wireless keyboard touch pad 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 radio-frequency (RF) transceiver 10, microcontroller 20, and keyboard 21 that is connected with microcontroller 20 and touch pad 22, the input signal of its keyboard 21 and touch pad 22 is launched to receiver by radio-frequency (RF) transceiver 10 after microcontroller 20 is handled.Described transmitter 1 also comprises feed circuit 30 (comprising battery 31 and charging circuit 32), and these feed circuit are connected with microcontroller 20 with radio-frequency (RF) transceiver 10 respectively powers.
Described receiver 2 comprises radio-frequency (RF) transceiver 40, the USB controller 50 that is connected with this radio-frequency (RF) transceiver 40, and the USB interface 51 that is connected with computing machine, this receiver 2 is delivered to computing machine by USB controller 50 after receiving signal from transmitter 1, and computing machine is carried out control operation.This receiver is connected with computing machine by USB interface, and powers to receiver by computing machine.
Described keyboard 21 comprises I/O matrix keyboard and left and right operating key, and described touch pad 22 is a capacitive sensing touch panel, and this keyboard 21 and touch pad 22 and radio-frequency (RF) transceiver 10, microcontroller 20, feed circuit 30 are as integral structure.When producing shift action on generation actuation of keys or the touch pad on the keyboard, microcontroller 20 in the transmitter 1 can generate corresponding button or movable signal, and be sent to radio-frequency (RF) transceiver 40 in the receiver 2 by radio-frequency signal generator 10, send this signal to computing machine by the USB controller again, realize the control corresponding operation.
The utility model adopts integral structure, has the advantages such as simple in structure, easy to carry, is specially adapted to meeting, drills Say, the aspects such as educational training and home computer amusement use.
