The invention is further described with reference to the accompanying drawings:
fig. 1 is a block diagram schematically illustrating a module structure of an intelligent exhibition hall voice broadcaster according to an embodiment of the present invention.
Detailed Description
The following describes an intelligent exhibition hall voice broadcasting device and a broadcasting method thereof in further detail with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and distinctly aiding in the description of the embodiments of the invention.
The intelligent exhibition hall voice broadcasting device has the core idea that the intelligent exhibition hall voice broadcasting device provided by the invention adopts a real-time control system based on a control chip, different instructions are sent according to different visiting states of tourists, the intelligent exhibition hall voice broadcasting device can be seamlessly connected with a voice chip and an ultrasonic module, various functions are conveniently realized, the working efficiency is improved, and more diversified experience is brought to the tourists by the application of the intelligent exhibition hall voice broadcasting device. The broadcasting method of the intelligent exhibition hall voice broadcasting device can effectively detect the distance between the tourist and the exhibit, carry out calculation and analysis, realize automatic voice broadcasting explanation, and indirectly overcome the defects of high human resource management cost and large labor cost waste when the tourist is rare.
Fig. 1 is a block diagram schematically illustrating a module structure of an intelligent exhibition hall voice broadcaster according to an embodiment of the present invention. Referring to fig. 1, there is provided an intelligent exhibition hall voice broadcaster, including: the control chip 11 is arranged in the broadcasting device cavity; the servo motor 12 is fixed outside the broadcaster and connected with the control chip 11; the ultrasonic module 13 is connected with the shaft of the servo motor 12 and is in signal connection with the control chip 11; the voice chip 14 is connected with the control chip 11; and the loudspeaker 15 is connected with the voice chip 14. The control chip 11 is connected with a five-volt power supply.
The control chip 11 acquires the distance signal of the ultrasonic module 13, converts the distance signal into a level signal and sends the level signal to the voice chip 14.
