Embodiment Construction
[0009] Specific examples are given below in conjunction with the accompanying drawings to further illustrate how the present invention is realized.
[0010] Such as figure 1 Shown, a kind of supermarket consumer density measuring system of the present invention comprises central control module, upper computer, wireless communication module and reader-writer, it is characterized in that, central control module is connected with upper computer, wireless communication module, reader-writer respectively connected. The ARM chip is used to control the RFID reader set on the supermarket shopping cart to detect the passive electronic tags with unique IDs on the shelves for data collection. The information collected by the central control module is transmitted to the upper computer through the wireless module, and the population density map is obtained.
[0011] Such as figure 1 As shown, the UHF module of the reader uses the M900 module chip and is powered by a single 3.3V power su...
