Detailed Description

Referring to fig. 1 and 2, an intelligent rotary exhibition stand comprises a base 1, a turntable 2, a speed reduction motor 5, a control circuit and a power supply 14, and is characterized in that: the lower parts of the turntables 2 are respectively provided with a light-shielding sheet 4 with the same radius and 90-degree intervals, namely the total 4 light-shielding sheets 4 are arranged, the upper parts of the bases 1 are provided with the groove-shaped optical coupling modules 3, and the installation radius of the light-shielding sheets 4 is from the center of the turntables 2 to the center of grooves of groove-shaped optical couplers on the groove-shaped optical coupling modules; namely, when the turntable 2 rotates, one of the shading sheets 4 can just penetrate through the center of the groove-shaped optical coupler on the groove-shaped optical coupler module 3 at a certain moment to shade light; a tray 9 is fixed at the corresponding position of the turntable 2 above the shading sheet 4 so as to place exhibits. The control circuit consists of a singlechip 10, a voice recording and playing circuit 11, a sound box 13 and a motor driving circuit 12, wherein an I/O port of the singlechip 10 is connected to a signal output end of the pyroelectric sensor 6 and is used for detecting whether a person approaches, and when the person approaches, the output level of the pyroelectric sensor 6 is changed from a low level to a high level; the pyroelectric sensor 6 is a commercially available pyroelectric sensor with the model number of SR602; the other I/O port of the single chip microcomputer 10 is connected with a signal output end of a groove-shaped optical coupling module 3, and the groove-shaped optical coupling module 3 is a commercially available product with the model number of ITR9606; the other two I/O ports are respectively connected to a playback control end and a fast forward control end of the voice recording and playing circuit 11, an audio output end of the voice recording and playing circuit 11 is connected with a sound box 13 through an audio output interface on the base 1, the voice recording and playing circuit 11 adopts a commercially available voice module product, the model is ISD1760, the recording duration is 60 seconds, recording and playing can be performed in a segmented manner, if longer recording time is needed, the models such as ISD17120 or ISD17240 can be selected, the recording durations are 120 seconds and 240 seconds respectively, and the detailed use method of the module refers to a technical manual provided by a merchant; the sound box adopts a commercially available 4 ohm 5-15W product; the single chip microcomputer 10 is also provided with two I/O ports which are respectively connected to a motor forward and reverse rotation control end of the motor driving circuit 12 and used for controlling the forward rotation, the reverse rotation and the stalling of the speed reducing motor 5; the motor driving circuit 12 adopts a commercially available motor driving module with the model number of L9110; the single chip microcomputer 10 is made of a domestic product, the model of the single chip microcomputer is STC8H1K08, and an upgrading program of the single chip microcomputer 10 can be downloaded through a program downloading interface on the base 1.

Specifically, when the spectator approaches the intelligent rotary exhibition platform, the output level of the pyroelectric sensor 6 is changed from low level to high level, the change detected by the singlechip 10 drives the speed reducing motor 5 to rotate, when one of the light-shielding sheets 4 below the turntable 2 rotates to the middle of the groove-shaped optical coupler on the groove-shaped optical coupler module 3 to shield light, the groove-shaped optical coupler module 3 outputs high level to trigger the external interrupt program of the singlechip 10, the singlechip 10 controls the speed reducing motor 5 to stop rotating and sends out a low level pulse to the fast-forward I/O port connected with the voice recording and playing circuit 11 to control the voice recording and playing circuit 11 to fast forward one section (the voice recording and playing circuit 11 points the pointer to the starting address of the next section of playback), and then the singlechip 10 sends out a low level pulse to the I/O port connected with the playback control end of the voice recording and playing circuit 11 to play playback commentary corresponding to the playback item in the forward tray 9.
