| Touch controller is a kind of intelligent operation control display device, is thetransmission between human and machine, is the information exchange and dialoguemedia interface between human and machine, is one kind of man-machine interface(called as Human-Machine Interaction-HMI). In the traditional industrial controlfield, man-machine interface (HMI) is also called as another name of touch controller.After decades of development, the touch controller based on configuration technology,has become a combination of computer science, cognitive psychology, ergonomics,aesthetics, linguistics and other disciplines of the product number. It had been used forindustrial detection, data acquisition, display and automatic control of the application,which really has strong function, easy to R&D for the second times and also it hasstable performance characteristics.The touch controller is based on investigation method&case analysis method andanalysis of the advantages&disadvantages of the traditional man-machine interface&application experience, then establish a strict and practical application demand,accomplish the touch screen controller hardware design and software design.Hardware design use the latest AM335x chip which mainly include hardware structure&hardware configuration&hardware design&PCB design; software design is tomake all unit parts function come true by fixing compiler function of PC software,also the software would be embedded into PC machine in the terminal.System design and implementation solution successfully solved ESD preventing&EMC&heat dissipation and other technical problems. This design really havepowerful configuration function which not only have better capabilities/scalabilitythan the existing products, also even can let the next-bit machine can work normallywithout any program which successfully make automation equipment being wellcontrolled, but also largely enhance the automation equipment R&D efficiency andfriendly interface capabilities!... |
