Abstract

The invention discloses a commodity monitoring system applied to a goods shelf. The commodity monitoring system comprises a power module, a sensor module, a signal processing module, a control moduleand an external communication module; the sensor module is connected with the signal processing module, the signal processing module is connected with the control module, the control module is connected with the external communication module, and the power module is connected with the sensor module, the signal processing module, the control module and the external communication module; and the sensor module obtains the pressure borne by the goods shelf, processes the pressure and outputs a voltage signal, the signal processing module converts the voltage signal into a frequency signal, the control module analyzes the frequency signal to obtain the pressure change amount and calculates the quantity change of commodities on the goods shelf according to the pressure change amount, and the external communication module transmits the quantity change to external communication equipment. The commodities needing to be replenished can be found in time, and the supermarket commodities are automatically monitored.

Description

technical field

[0001] The invention relates to the technical field of automation, in particular to a product monitoring system. Background technique

[0002] Supermarkets are a kind of operating state characterized by automatic pick-up and self-service. It has been widely welcomed by customers in a new way of open-shelf sales and customer self-selection.

[0003] With the rapid popularization of automation technology and the rapid development of unmanned supermarkets, most of the current operating models of unmanned vending supermarkets are mainly automatic vending and smart checkout. The replenishment technology is not yet mature. Traditional supermarket commodity monitoring is mainly manual inventory. This method is inefficient and cannot monitor the sales of goods in time, and cannot find the goods that need to be replenished in time, which seriously affects the overall economic benefits of the supermarket.
