Abstract
A portable wireless computer terminal connected with wireless mode is composed of wireless terminal and wireless interface. The video, audio and control signals can directly transmitted in wireless mode, so the data processing and storage are no necessary. More such terminals can be connected to a single host of computer. It has very small size.
Description
The invention belongs to the computer product field, is to utilize wireless technology that present computer is improved, and makes its people's that are more convenient for use and brings into play the effect of computer more fully.
Present PC, generally form by main frame, keyboard, display and mouse, link together with cable between they are mutual, this just determined computer use this also must be limited in the scope that computer places, and generally be placed on the computer desk, so before people just can only be sitting in computer desk, can not move freely, so just make people's fatigue easily, use not convenient.Because the PC volume is big, and very heavy, is difficult for moving, and also causes a lot of inconvenience to people.Notebook computer has solved some difficulties to a certain extent, but it also exists the shortcoming that some can't overcome, costing an arm and a leg of it at first, and general family is difficult to accept, and can't upgrade, and damages maintenance difficult easily.Secondly its weight is still not light, and power consumption is also bigger, and is still very inconvenient in moving freely use.And present notebook computer can't wireless direct online, must so not only use trouble, and expenses of surfing Internet rise greatly by means of mobile phone if get online without being tethered to a cable.So notebook computer also can't solve the inconvenience in the above-mentioned computer use, and the present invention just well solves these problems.
The present invention is the computer terminal that is connected by wireless mode by a kind of, terminal is only formed (Fig. 1) by keyboard [1], mouse [2], flat-panel monitor [3], terminal is by wireless mode host computer to be controlled and exported, its volume can be done forr a short time, can accomplish notebook-sized truly.Can use it anywhere, lie on a bed, be sitting on the sofa.It can make people use computer more freely, and can realize getting online without being tethered to a cable near host computer.
The present invention mainly is made up of host computer wave point part (Fig. 2) and wireless terminal (Fig. 3) two large divisions.The host computer wave point partly produces circuit, carrier transmit circuit, carrier wave receiving circuit, demodulator circuit etc. by carrier signal and forms.Wave point partly is to link to each other with sound card, display adapter and keyboard and mouse adapter circuit on the host computer, sound card, display adapter and keyboard and mouse adapter circuit are sent sound signal, picture signal and the control signal of computer output into carrier signal respectively and are produced circuit, carrier signal is modulated, to launch with the carrier signal of sound signal, picture signal and the control signal of computer by the carrier transmit circuit again, receive by wireless terminal.The carrier wave receiving circuit of wave point part amplifies the control carrier signal that wireless terminal emits, and sends into demodulator circuit, and carrier signal is reduced to control signal, sends into the keyboard and mouse adapter circuit, to finish the control of wireless terminal to computer.Wireless terminal partly produces circuit, carrier transmit circuit etc. by carrier wave receiving circuit, demodulation and demultiplexing circuit, audio output circuit, display circuit, display screen, keyboard and mouse control circuit, keyboard and mouse, carrier signal and forms, the carrier wave receiving circuit of wireless terminal is that the carrier signal that host computer emits is received, and send into demodulation and demultiplexing circuit, carrier signal is reduced to audio frequency, image and control signal, thereby finishes the output function of terminal computer.Keyboard and mouse by wireless terminal can produce control signal, send into carrier signal and produce circuit, and carrier wave is modulated, and are launched by the carrier transmit circuit again, are partly received by host computer, thereby have finished the control of wireless terminal to host computer.
Screen of this wireless computer terminal and keyboard are also separable, the online or do not use under the situation of keyboard, make terminal become smaller and more exquisite, and can pass through special software, can allow a plurality of terminals use same host computer, excavated the use resource of computer greatly, so just can a plurality of people use same computer simultaneously, thereby solve the difficulty that many people use a computer inconvenience.
This wireless computer terminal is a kind of brand-new wireless terminal connected mode, it is the transmission of directly carrying out image, audio frequency and control signal, need not processing and storage to data, thereby does not need data processing CPU and memory device, greatly reduce cost and volume, also reduced power consumption simultaneously.
The present invention is the future development trend of PC, it can use the computer that originally uses in any one place on desk, make people spatially obtain liberation, make computer have more amusement and recreation, meet the requirement of people more the high-tech product human oriented design.
Claims (5)
1. a portable wireless computer terminal is made up of host computer wave point part and wireless terminal two large divisions.It is characterized in that by wireless transmission image, audio frequency and the control signal of computer, accomplish the control and the output of host computer, need not processing and storage to data, can a plurality of terminals use same host computer simultaneously, the screen of terminal can separate with keyboard.
