Embodiment Construction

[0035] Such as figure 1 The block diagram of the circuit structure of the handle according to the present invention is shown, wherein the button processing circuit 104 is realized by using a relatively common GPIO scanning method, and is used to scan the function buttons and send the button information to the main control unit 101; Bluetooth or RF module Group 102 transmits the control information of the handle to the host; the bluetooth unit adopts BCM2042, which is an excellent single-chip bluetooth module, which integrates the HID protocol and a complete bluetooth protocol stack. In addition, the chip integrates 8051MCU and 8K RAM with Certain data processing functions (it can be used to share part of the work of the main control unit, such as: responsible for the realization of button scanning, background data processing of 3D motion and infrared modules, and control functions of other modules (motors, etc.). Figure 5 shown). RF uses NORDIG nRF24L01 solution, its biggest...

Abstract

The invention discloses an operating handle and a moving direction judging method of the operating handle, wherein, the handle comprises an external shell body, a key-press processing circuit, a Bluetooth or RF module group and a main control unit; and the handle is characterized in that the handle also includes: an infrared module group which is used to scan infrared signals sent by an infrared light-emitting diode unit; and a 3D movement sensing unit which is used for producing movement velocity signals and rotation angle signals in three dimensional directions; the main control unit also processes the infrared signals sent by the external infrared light-emitting diode unit scanned by the infrared module group to form the directional information; meanwhile, the main control unit also processes the handle speed and angle information transmitted by the 3D movement sensing unit; and the main control unit processes the information and then transmits the information to a host end through the Bluetooth or RF module group. The method comprises the steps of infrared signal transmission, scanning, comparison and sending; and the handle has advantages of practicality and convenience and novel structure, and is suitable for being widely promoted in the domestic electric appliance remote control field.

Description

technical field [0001] The invention relates to an operating handle, in particular to a dynamic motion sensing operating handle and a method for determining its motion direction. Background technique [0002] Traditional audio-visual equipment mostly uses infrared transmission remote control buttons to operate. Although its technical application is very mature, its function is single, and it is only used as a button-type operation panel without interactive functions; as people's quality of life, In pursuit of life diversity, a large number of game controllers with interactive functions have been developed, which enrich people's daily life. However, this handle with interactive functions is only limited to the field of games. In the process of high-definition media and network entertainment gradually being used in home audio-visual equipment, the original remote control button operation handle is far from meeting the needs of modern people, so there is an urgent need for a d...
