Shop monitoring system based on multi-purposes alarm device, and multi-purposes alarm device and central management server for the same

摘要

The present invention relates to a store monitoring system based on a multi-purpose alarm device, and a multi-purpose alarm device and a central control server therefor. The present invention, IoT on / off switch 720; Photo coupler 730; MPU 740; A light-emitting diode 750; An alarm signal generator 760; Speaker 770; And an RFID tag 790; Including, as infrared light is emitted from the infrared light emitting diode 730a, the MPU 740 is configured to set the free display mode or the anti-theft mode when the infrared light is not received by the light-receiving transistor 730b, the IoT mode setting switch 741 ) Is set to the display mode or the anti-theft mode, and when the determination result is set to the anti-theft mode rather than the display mode, the MPU 740 outputs an alarm control signal to the alarm signal generator 760, It is characterized in that the sound signal is output from the speaker 770 connected to the alarm signal generator 760 and the light emitting diode 750 emits light. Accordingly, it provides the effect of setting a unique frequency for each product sold by each store, preventing the loss of the product according to the mode selection for the product for which each frequency is set, and tracking in case of theft of expensive products. It provides an effect that allows it to be recovered effectively.
