The realization of the function of downloading the banknote information (the function of designating banknote interception), related departments (such as a people bank) send the banknote information (currency, version, denomination and crown word number) to be intercepted to a designated server, and the information is pushed to the ESP32S2 by the server through the Internet and WI-FI, and the ESP32S2 receives the complete banknote information content to be intercepted and communicates with the point A through a USB module integrated with the ESP32S2 after the banknote information content is successfully verified. The point A records the information of the bank notes to be intercepted, when the point A detects the bank notes conforming to the interception information, the alarm is automatically prompted, and meanwhile, the information of successful interception is sent to the ESP32S2 through the point A USB port and the TUSB2046BDR chip. And then transmitted to the designated server through the wireless internet by the wireless network module of ESP32S 2. And the information is forwarded to related departments (such as a people bank or a public security organization) through the server, and the related banknote information and the position of the point A are located.
As shown in fig. 5, in the implementation of the mobile payment function (dynamic two-dimensional code payment), the payee inputs the amount of money to be charged at point a, point a sends the amount information to the ESP32S2 through the USB port and the TUSB2046BDR chip, and the wireless network module of the ESP32S2 transmits the amount information to the designated network payment operator through the wireless internet. The operator associates the payee account information according to the machine number and generates a two-dimensional code according to the amount of money, and the generated two-dimensional code is issued to ESP32S2 through the wireless internet. And then the USB module integrated by the ESP32S2 is communicated with the point A, and the point A screen displays the payment two-dimensional code.
The payer checks the code for payment, and when the network payment operator detects that the payment is successful, the payment is sent to the ESP32S2 through the wireless Internet. The USB module integrated with ESP32S2 communicates with point A, and the point A screen displays the successful payment.
