Description

Intelligent radio body sense mouse

Technical field

The utility model relates to a kind of intelligent radio body sense mouse that can resolve human hands attitude, belongs to electronic applications.

Background technology

Along with the development of computer network and electronic technology, the application of new technology also progresses into the every aspect in life, all the time, computer mouse is all more popular, maximum wire mouses is used not depart from the restriction of space and induction base plate, this just limits the steering range of people to computer to a certain extent, provides to more computer users and serve more easily.Even if also there is certain drawback in the wireless mouse just come into vogue now, although they can break away from the constraint of wire mouse moving range, but leave induction base plate still can not conveniently handle, farther service range in early days and get the brush-off, along with the development in pluralism of computer, more people recognizes the other style function of computer, now, the point that the service range of computer also becomes numerous user to pay close attention to, along with emerging in large numbers and the exploitation of a large amount of teaching software of large quantities of outstanding multimedia courseware, utilize multi-media classroom to carry out teaching and be more and more subject to people's attention.But people, while affirmative multimedia teaching effect, also recognize its major defect: teacher is saying that class hour is often confined in front of a computer, and the content of courses and instructional mode are subject to the restriction of teaching equipment.

Summary of the invention

The utility model object is the constraint in order to solve teacher's that scope of activities that wire mouse brings when using multimedia gives lessons, teacher is avoided to confine the phenomenon before multimedia, use this utility model, fully can use multimedia technology, the initiative of teacher can be played again, can not only classroom efficiency be improved, and can do one's bit for the teaching of schoolman.

The wireless mouse of existing design can only realize some simple page-turning functions to PPT, and better can have individual laser mark function, and this design makes wireless mouse have more strong large function.It is a kind of intelligent radio body sense mouse that can resolve human hands attitude.

A kind of intelligent radio body sense mouse, it is characterized in that, it comprises central processing unit (1), wireless signal transmitting module (2), reception of wireless signals module (3), power supply and reseting module (4) and memory module (5), the output terminal of reception of wireless signals module (3) is connected with Demo Computer, the power output end of power supply and reseting module (4) is connected with the power input of central processing unit (1), the input/output terminal of memory module (5) is connected with the communication input/output terminal of central processing unit (1), select NXP1227 chips process information, responsible hand gestures resolves part, the output terminal of wireless signal transmitting module (2) is connected with the input end of central processing unit (1), central processing unit (1) is primarily of STM32 chip controls, be responsible for receiving gyroscope resolves gained data to human action, the sheet selected control signal output part of central processing unit (1) is connected with the control end of wireless signal transmitting module (2).

Advantage of the present utility model: the intelligent radio body sense mouse volume of the utility model design is little, and cost is low, multiple functional, and dirigibility is strong; By resolving hand gestures, by wireless, data are sent to receiving end, receiving end, to functions such as computer transmit operation instructions, is responsible for communicating with the USB of computer.Main advantage is the power of an integrated key mark, can realize gesture and control, PPT mark and writes, can remove fast the vestige that PPT delineates; Only need a button just can complete broadcasting and the exit function of PPT, handled easily, to save time.

Embodiment

Embodiment one: this embodiment is described below in conjunction with Fig. 1, Fig. 1 is the circuit theory diagrams of the wireless control chip STM32 that this makes, its primary responsibility wireless transmission part, receive gyrostatic attitude algorithm data, by the perfect adaptation with NXP1227 main control chip, thus realize the function that operator thinks realization.

Embodiment two: present embodiment is described below in conjunction with Fig. 2, present embodiment is described further embodiment one, total system is divided into launching and receiving two parts, radiating portion adopts NXP1227 chip to be responsible for hand gestures and resolves, by wireless, data are sent to receiving end, receiving end, to computer transmit operation command function, is responsible for communicating with the USB of computer, thus is realized the various operations to computer.

It is fast that wireless communication section of the present utility model has signal transmission speed, the advantages such as dirigibility is strong, can compatible existing all Windows control systems, and former wireless mouse is restricted to operating system, and input signal in fixed form can only be received, versatility is poor.

Embodiment three: present embodiment is described below in conjunction with Fig. 3 and Fig. 4, the structure composition of present embodiment is relatively simple, NXP1227 and STM32 two main control chips are only had to control radiating portion and the receiving unit of computer mouse respectively, radiating portion is resolved hand gestures by NXP1227 chip, finally by NRF24L01 wireless transceiver, data are sent to receiving end, after receiving end receives the command signal of wireless transmission, computer end is sent signal to immediately by STM32 main control chip and usb protocol, after computer recognition instruction signal, along with the change of the hand gestures of people realizes corresponding operating.

Embodiment four: present embodiment is described below in conjunction with Fig. 5 and Fig. 6, present embodiment is mainly described system part part, people are according to the needs of oneself, mouse is carried out to the movement of different azimuth, through inner attitude algorithm, add the operation to button on mouse, different command signals is sent to computer, after Radio reception section receives the hand motion attitude of people and the command operating signal of button, by usb protocol, operational order is sent to computer end, thus realizes the operation to computer.
