Abstract

The invention discloses a power regulating method and apparatus of an infrared touch frame. The power regulating method comprises the steps of detecting whether the shielded time of the front side of the touch surface of the infrared touch screen exceeds a preset time threshold value or not; monitoring whether the state of the front side of the touch surface of the infrared touch screen is changed from a being-shielded-state into an un-shielded state or not; and if the shielded time of the front side of the touch surface of the infrared touch screen exceeds the preset time threshold value and the state of the front side of the touch surface of the infrared touch screen is changed from the being-shielded-state into the un-shielded state, resetting or rapidly regulating the emitting power of the infrared touch screen. The power regulating method can solve the problem of abnormal operation when the state of the front side of the infrared touch screen is changed from the being-shielded-state into the un-shielded state, so as to realize the rapid resetting or regulation on the emitting power of the infrared touch screen.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power adjustment method and device for an infrared touch frame. Background technique [0002] Multimedia teaching is also called computer assisted instruction (computer assisted instruction, CAI). Originated in the 1980s, a variety of electronic media such as slides, projections, audio recordings, and video recordings were used and used in classroom teaching. Since the 1990s, with the rapid development and popularization of computer technology, multimedia computers have gradually replaced the comprehensive use of various teaching media in the past. In the early 21st century, with the maturity of infrared touch technology, interactive smart panels with infrared touch frames are increasingly used in teaching, bringing more convenience and interaction to modern teaching. [0003] An existing common application scenario such as figure 1 As shown, the smart tablet Z1 with the...
