Palm intelligent game computer that can inducing palm action

Technical field

The invention belongs to electronic game machine.Be particularly related to a kind of palm intelligent game computer that can inducing palm action.

Background technology

In today that commercial prosperity, life are had much to do, people always want to seek a leisurely enjoyment outside busy, with the nervous mood of releiving, so various palm electronic game machine at modern's the corresponding appearance of demand, and just has been subjected to consumers in general's favor at the beginning of the invention.

The palm electronic game machine that is sold on the market is of a great variety now, but is to need the intelligence of service orientation key or craftsmenship recreation mostly, and the operation armrest refers to finish, and is irrelevant with self attitude and the motion of game machine.Also not having in the market can be according to game machine self attitude and the game machine that moves and operate, and there is the bigger market space in the present invention.

Summary of the invention

The purpose of this invention is to provide a kind of horizontal attitude or direction that needs to change game machine, do not need to use operation push-button just can control the palm intelligent game computer of the energy inducing palm action of the controlled object motion in the recreation.

The objective of the invention is to be achieved through the following technical solutions: this palm intelligent game computer be connect around microprocessor that signal detection module, data memory module, LCD MODULE, power management mould are fast on the respective lead pin, serial communication modular and operation keyboard, accelerometer and magnetometer are connected in parallel on the input end of signal detection module, serial communication modular is connected with PC again, and acoustical generator is contained in the game machine box; The described signal that accelerometer and magnetometer measured as sensor through the signal detection module signal deteching circuit to detection signal amplify respectively, Filtering Processing, through A/D sampling input microprocessor, the signal that the microprocessor utilization is surveyed goes out the residing attitude of game machine by computed in software at last.And calculate moving direction and the translational speed of controlled object in Game Zone thus.Wherein the moving direction of object is the direction of object gliding acceleration maximum in Game Zone, and Liquid Crystal Module is to show game process, and EEPROM is used to store game data, and serial communication modular is used for realizing the information transmission between microprocessor and the PC.

Wherein the attitude algorithm of game machine is:

Set up earlier the game machine position geographic coordinate system north-Dong-ground (being N-E-D), (X--is in the game machine symmetrical plane, points to game machine motion forward direction by barycenter to be fixed on the game machine coordinate system X-Y-Z of game machine; Y-is perpendicular to the game machine symmetrical plane and point to right-hand; Z-is in the game machine symmetrical plane and perpendicular to the X-axis directed downwards), the signal that the microprocessor utilization is surveyed goes out the residing attitude of game machine by computed in software.And calculate moving direction and the translational speed of controlled object in Game Zone thus, speed is:
