The controller is operated by a hand, the shell of the controller is provided with a cursor operating rod, a cursor operating key, a grouping key, a selecting key and a multiple-valued key, and the controller is internally provided with a cursor operating and detecting circuit, a three-dimensional key value processing module and a 2.4G radio circuit. The controller finishes the three-dimensional key value conversion and cursor operation processing by taking an MEGA 88 as a processing core, and accesses the processed cursor displacement value, a cursor operation value, a cursor rolling value and a standard keyboard value to the computer through the connector for the procedure in the computer to use.

Description

Computer remote controller

Technical field

The present invention is the computer external human-computer interaction device, can carry out the control of remote-controlled operation completely to computing machine easily.

Background technology

Also there are a lot of problems in computer remote controller in the market.At first mostly existing products in markets is to realize cursor running fix with direction button or trace ball, can't reach the quick pinpoint requirement of cursor on the principle.Secondly mostly the keyboard input is the mode of operation of imitation cell phone keyboard, can't realize the function that computer keyboard is complete, and operation is very complicated.Be that wireless transmission is used infrared ray control more then, need to aim at computer operation, limited the dirigibility of operation.

Summary of the invention

Purpose of the present invention with the problem that needs to solve is: realize the computer remote controller of a complete practicality, solving cursor can not accurately locate fast, and the keypad function imperfection is succinct, long-time operation fatiguability, the problem of use very flexible.

The technical solution adopted in the present invention is: the present invention is made up of controller and connector two parts, carry out communication by built-in 2.4G radio-circuit between connector and the controller, connector is realized being connected with USB interface of computer, and controller carries out the cursor operations signal Processing and three-dimensional button numerical value is handled.

The cursor operations signal processing technology is the dynamics of finger tip and direction to be delivered to by the cursor operations bar cause changes in resistance on the strain resistor, and then be transformed into the voltage signal of variation, through operational amplifier signal is inserted single-chip microcomputer, through carrying out signal Processing after the analog digital conversion, in conjunction with four cursor operations key assignments, finally convert the cursor shift value of standard to, operating value and roll value insert the accurately location and the operation control fast of computer realization cursor by connector.

Three-dimensional button numerical value treatment technology is that the button with telepilot is divided three classes, and is respectively four grouping keys, four selected key and 16 many-valued keys.16 key assignments of each many-valued key definable, and be divided into four groups, every group of four key assignments, each concrete key assignments is chosen by selected key and grouping key.The telepilot of such one 20 quadruple linkage can be realized the key assignments of 256 reality, except that the key assignments that covers the traditional computer keyboard fully, can also increase some quick functional keys commonly used of computing machine, and reduce the operating speed of complicated operation degree and raising button greatly.

The invention has the beneficial effects as follows: the perfect in shape and function practicality, simple to operate laborsaving, use flexibly, cheap.

Embodiment

The present invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is the contour structures synoptic diagram of this telepilot, comprises controller 6 and connector 7, and 4, ten six many-valued keys 5 of 1, four cursor operations key of a cursor operations bar, 2, four groupings, 3, four selected key of key are arranged on the controller 6.Wherein four grouping keys are respectively common functions, English input, sign digit, input in Chinese.Method of operating is at first connector 7 to be inserted the main frame computer USB interfaces, insert good after, stay the convenient plug of machine outward, in several meters far away distance, hold controller 6 then and operate for one section of nearly finger tripe size.

The cursor operations step, the light finger flicking is lived cursor operations bar 1 and is exerted all one's strength up and down, can observe cursor on the graphoscope follows the power thrusts of finger and moves, translational speed is directly proportional with the finger dynamics, can detect by the cursor operations bar and can easily realize the accurate fast location of cursor, carry out clicking of cursor, attribute as need, rolling operation can be operated the corresponding button in the cursor operating key 2.

Three-dimensional button operation step, at first finger is moved on the grouping key 3 by next key, as English enter key, this moment, keyboard switched to English input state, pressed next key for 5 li at many-valued key, such as the key that is designated as AaBb, press next key for 4 li in selected key then, as the S3 key, this moment, controller 6 will send to the 3rd letter b in the AaBb key in the computing machine, finished once input.

Fig. 2 is the electrical block diagram of this telepilot, comprises controller circuitry 10 and connector circuit 11.Controller circuitry 10 is by cursor operations detection architecture 1, low-power consumption four high guaily unit circuit 2, and power-supply battery 3, three-dimensional push-button array 4, MEGA88 single-chip microcomputer 5 and 2.4G radio-circuit 6 are formed.Connector circuit 11 is by USB interface 7, and MEGA8 single-chip microcomputer 8 and 2.4G radio-circuit 9 are formed.Wherein 2.4G radio-circuit 6 and 2.4G radio-circuit 9 realize wireless telecommunications by nRF24L01 chip and circuit board antenna.

The implementation procedure that cursor operations detects is that the cursor operations detection architecture 1 in the controller circuitry 10 converts the pressure of pointing to four tunnel small signal simulation voltages, through low-power consumption four high guaily unit circuit 2 this small-signal is amplified to about 1 volt, then this four road voltage signal is inserted four tunnel simulating signal pins of MEGA88 single-chip microcomputer 5, finish the analog and digital signal conversion in this single-chip microcomputer inside, further carry out digital signal processing, convert the cursor shift value to, in conjunction with detected button operation value from cursor operations detection architecture 1, roll value, be combined into the cursor operations normal data, launch through 2.4G radio-circuit 6.2.4G radio-circuit 9 in the connector circuit 11 sends to the cursor operations normal data that receives in the MEGA8 single-chip microcomputer 8, and the USB message that converts standard to sends to computing machine by USB interface 7 and handles for its internal processes.
