Embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.

Along with the widespread use on mobile phone of QWER full keyboard, and cause that new a burst of trend, full keyboard have satisfied requirement and the needs of simple and convenient operation of people's quick input undoubtedly.The present invention adopts very unique two-sided design, and as shown in Figure 1, the front is the common remote controller button, constitute by a plurality of keypads, and the keypress function signal that the input user selects, the user can realize the control to televisor through the front common key-press.As shown in Figure 2, reverse side then is to have added present popular QWER full keyboard, and the function of integrated computor-keyboard pushbotton can realize importing fast and operation easily.Simultaneously, battery also is placed in the middle part of back side button.Two-sided telepilot can carry out the judgement of pros and cons through the acceleration of gravity sensor, makes dual surface keyboard in use can freely switch, and the consumer can realize that various literal are fast imported and other are controlled through it.

As shown in Figure 3, the present invention includes MCU1, remote controller key 2, said remote controller key 2 links to each other with MCU1; Also comprise acceleration of gravity sensor 3, QWER full keyboard button 4; Said acceleration of gravity sensor 3 links to each other with MCU1, and said QWER full keyboard button 4 links to each other with MCU1, and said MCU1 adopts the microprocessor chip that has the zigbee/RF4CE protocol function; For example use CC2530, receive the measuring-signal of acceleration of gravity sensor 3 through communication interfaces such as I2C, SPI, UART; According to the button input operation of (comprising common key-press or QWER full keyboard button), export control signal simultaneously.

Two-sided telepilot has adopted zigbee or RF4CE communications protocol and terminal device to communicate; Overcome a series of shortcomings of traditional IR remote controller, command range is very far away, and telepilot can be controlled by the penetrate thing; Very low of power consumption simultaneously, energy savings.

The two-sided telepilot method of discrimination of phase pros and cons duty in use is following: after opening acceleration of gravity sensor 3, can confirm the state of two-sided telepilot based on index value with perpendicular to the direction of the sensitive axes (z axle) of ground level.The state of two-sided telepilot is meant mainly that specifically two-sided telepilot is front button or reverse side button.Particularly, can be greater than zero or judge that less than zero the axial value of expression z can be through averaging to index value in the buffer area and after judging, obtaining according to index value.In acceleration of gravity sensor 3 operational processs, the buffer area of MCU1 has at regular intervals the index value that (for example at interval 0.1 second, or 0.2 second) is obtained, and whether through the analysis to the said index value in the buffer area, it is stable to judge sensitive axes.For example extract that index value is 14 in the buffer area; If in these 14 data entirely just or in complete negative and the buffer area index value to be no more than 3 (first thresholds) unequal; And when absolute difference is not more than 2 (second threshold values); Judge that present sensitive axes is stable, having only sensitive axes is that the stable data of calculating are only valid data, otherwise is invalid data.Further, can just export 1 if average is a positive number to the computing of averaging of the index value in the buffer area, if average is just output-1 of negative, and output 1 or-1 be the axial value of said expression z.Especially, if the value of the data in the buffer area entirely on the occasion of and to judge sensitive axes stable be sure output 1, if entirely for negative value and to judge sensitive axes stable be output-1 certainly.If output valve is 1, represent promptly that greater than zero what then judge input is the reverse side button; If output valve is-1, represent promptly that less than zero what then judge input is the front button.

During practical implementation, along with the variation of each sensitive axes acceleration, index value also can change to some extent, and the index value that is read in the schedule time is deposited in the buffer area, can judge whether sensitive axes is stable through the data of analyzing in this buffer area.Desirable 3, the second threshold values of said first threshold are desirable 2, and promptly the quantity when sensitive axes different index value in buffer area is less than or equal to 3, and the difference between each index value all is less than or equal to 2, can confirm that this sensitive axes is stable.For instance, suppose that the index value of z axle in buffer area comprises: 22,22,22,21,21,20,20,20,19,19,18,18,17,17.Analysis through to the index value in the buffer area can be known: the quantity of z axle different index value in buffer area has 6; And difference is 4 between minimum index value and the maximum index value; The difference that has not satisfied between each index value all is less than or equal to 2, confirms that then the x axle plays pendulum.Suppose that the index value of z axle in buffer area comprises: 2,2,2,2,2,2,3,3,3,3,3,3,3,3.The quantity of z axle this moment different index value in buffer area is merely 2, and difference is 1 between minimum index value and the maximum index value, and the difference that can satisfy between each index value all is less than or equal to 2, confirms that then the z axle is in steady state (SS).Need to prove that the difference between the index value refers to the absolute value of difference between the index value.

Except that the foregoing description, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
