  • the present inventive concept relates to the control of a machine unit by means of a graphical user interface module. More specifically, the present inventive concept relates to a graphical user interface module and a method for controlling the machine unit with the graphical user interface module.
  • Graphical user interfaces are used to provide a simpler control of electric devices ranging from mobile phones and video games to microwave ovens.
  • Implementing a graphical user interface may be expensive in respect of developing the appropriate software. For large scale manufacturing, it may not be as problematic with these costs, but however, for smaller production lines, and products that are frequently updated, and thereby in need of new graphical user interfaces, the development costs are not negligible.
  • US7100118 discloses a graphical user interface engine for embedded systems.
  • a control system for controlling a device operates such that the burden of accepting human input and providing output to a human user by means of a display, is laid on a second processor, other than the embedded processor.
  • the burden of the handling of user input and output is laid on a second processor, the costs for developing a graphical user interface are still high, especially in view of smaller production lines.
  • a general object is to provide a device and method for controlling a machine unit. This and further objects will be described further below.
  • a graphical user interface module arranged to be connected to a machine unit for controlling the machine unit, the graphical user interface module comprising: an input module being arranged to receive user input signals, a display module arranged to display a status of the machine unit; and a control module arranged to communicate with the display module, the input module and the machine unit, the control module comprising: a dual port memory arranged to store user input signals from the input module and status signals from the machine unit, and a processing unit operatively connected to the dual port memory, the control module being structured and arranged to retrieve the status signals from the dual port memory and sending them to the display module, and to retrieve user input signals from the dual port memory and sending them to the machine unit to control said machine unit.
  • Using the graphical user interface module according to this first aspect is an advantage for companies that have realised the importance of an intuitive and easily handled user interface, but who do not have the time or possess the knowledge of developing a high standard user interface.
  • the graphical user interface module is for example of interest for companies producing small volumes of products.
  • One reason for this is that the development of high standard user interfaces most often is related to software program- ming, and thereby the cost of developing a high standard user interfaces are usually not highly dependent on the number of products produced.
  • a machine unit should be construed as a device comprising a CPU, which CPU, when receiving instructions, executes the instructions and thereby controls the device.
  • the control module may provide user input signals to a processor of the machine unit. Accordingly, the CPU of the machine unit may execute the user input signals and thereby control the machine unit.
  • the graphical user interface module may be used in connection with a variety of different types of machine units, such as e.g. washing machines, microwave ovens or other household appliances, or ATMs. Hence, an effect which may be obtainable thereby, is communication with, and control of machine units.
  • the graphical user interface module may further comprises: a data communications interface being connectable to an external screen planning module for modifying the appearance of the graphical user interface module, and a settings memory for saving configuration settings of the graphical user interface module received from the external screen planning module.
  • the external screen planning module is defined as a device or system which, when connected to the graphical user interface, may modify the graphical user interface of the graphical user interface module to comprise control functions adapted to the particular machine unit.
  • a control function can be any type of function related to the control of the machine unit, manifested as e.g. a graphical icon on the display module of the graphical user interface module.
  • An effect which may be obtained thereby is providing a general graphical user interface module which may be adapted to a machine unit- specific graphical user interface.
  • the time of developing a graphical user interface may be shortened, and the development costs of new software may be reduced. Consequently, a customized graphical user interface may quickly be obtained and thereby providing faster response to changes and updates in products, and supporting small production quantities in the reduced development costs.
  • the processing unit may be connected to a first port of the dual port memory and the machine unit may be connectable to a second port of the dual port memory, enabling simultaneous access to a value at an address in the dual port memory.
  • the dual port memory may act as a buffer in the sense that the input module, the display module, and the CPU of the machine unit may exchange user input signals and status signals.
  • a status signal is defined as a signal comprising a status of the machine unit, provided by the CPU of the machine unit. Also, compatibility with a wider range of different types of machine units may be achievable.
  • the control module may be structured and arranged to receive status signals from the machine unit and modify a value in the dual port memory based on the status signals. Status signals may thus be provided to e.g. the display module, thereby achieving the modular design of the graphical user interface module and the machine unit, i.e. that the graphical user interface module may be provided by e.g. a second party manufacturer.
  • the input device may comprise a touch screen. Thereby, a user interaction with the machine unit through the graphical user interface module may be simplified.
