Touch screen electronic pneumatic measuring instrument

1. Principle of pneumatic measuring instrument
       Pneumatic measuring technology is a technology that measures the size of workpieces through air flow and pressure. In order to achieve precise measurement, pneumatic measuring instruments utilize the physical principle that both flow and pressure are proportional to the size of the gap, while pressure and flow are inversely proportional to each other.
2. Project Overview The
     air pressure signal data acquisition part uses F103 and ADC124S021 to implement four-way air pressure signal acquisition, and communicates with the touch screen through the 485 port. The display part adopts MCGS configuration touch screen, which is responsible for interface display, parameter setting and data storage.
 
      The interface of the touch screen part is as follows: The final project
of plug definition on the collection board
 
was imported into Lichuang, so there is no actual board making. If you need to make a plate, please check it yourself.
