With the increase in the amount of currency and the acceleration of the circulation speed, the banknote sorting machine is becoming more and more important. The banknote sorting machine is a financial tool with the function of sorting banknotes. The sorting machine adopts touch screen, which greatly improves the efficiency of banknote management.
The touch screen is responsible for the user's input and parameter setting, and feeds back the running results of the banknotes to the user in real time. The running speed of banknotes is fast, which causes the communication between the main control and the display to be easily blocked. This paper adopts the multi-buffer queue mechanism.
The touch screen supports various configuration controls:
1. Operation button control: Select the control, and drag a frame of the required size anywhere on the screen, that is, the control is established.
2. Dynamic picture control: Change the picture according to the change of the corresponding value of the variable address of PLC or single chip), display the current value in the form of picture, can control the animation play, stop, pause, play the previous frame, the next frame and the specified frame, and also can control the picture. Perform movement control to move according to a predetermined trajectory.
3. Curve control: The user MCU only needs to send AD sampling data, and the serial screen will automatically fit and display it dynamically.
4. Progress bar control: It is a control that displays digital form. It is mainly used to display analog data, such as temperature, pressure, flow, etc. It displays data in percentage form according to the set full and zero limit values. The direction of change can also be set as desired.
5. Quotation function: It is convenient to query the current alarm status and alarm history records, so that the production status and safety of the equipment can be seen at a glance to prevent accidents.
