Description

technical field [0001] The invention relates to the field of commodity display, in particular to an intelligent commodity display shopping guide system. Background technique [0002] The existing product display and shopping guide system conducts shopping in the following way: After inputting the price of the corresponding product in the computer, the price information is displayed through the display module; Display; through the sensor module to identify the customer's location, it is possible to judge the area where the customer flow is not large, so as to promote and sell the product through the loudspeaker, improve the popularity of the product in the area, and increase the sales volume. The use of the display module can comprehensively, dynamically and richly display all kinds of information required by the product on the interface, so that customers can fully understand the product information; when there are few customers, it will automatically enter the mode of selli...

AI Technical Summary

Problems solved by technology

However, the power supply part of the traditional commodity display shopping guide system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain

In addition, due to the lack of corresponding circuit protection functions in the power supply part of the traditional commodity display shopping guide system, such as the lack of signal interference prevention functions, the safety and reliability of the circuit are poor
