A device, system and computer implemented method to display and process technical data for a device in an industrial control system.
The invention concerns a method to display, present and manipulate technical data of one or more industrial devices using a computer program for control, configuration or condition monitoring for one or more devices in an industrial or commercial plant. The invention relates in particular to a method of using an active display device to provide an improved Human Machine Interface in the form of a graphical user interface suitable for more than one person to use and/or collaborate with other persons for the purposes of controlling, simulating, testing or for retrieving data about one or more industrial devices.
In control room environments, and other environments requiring task collaboration (both onsite and remote), people have a need for a common (physical) place for presenting and sharing information as well as interacting with information. Most of today's control room have conventional large screens for presenting information overview but the operators cannot actively interact with such information presented at the large screen.
A common problem is that all people involved in solving a problem, making a decision or planning need to be able to access information in addition to interacting with information. The situation is improved when people can discuss a sketch, drawing or a computer visualisation representing a problem or the background of a problem. In control rooms, the problems to be solved may typically be too complex to be sketched by hand. Control room operators use overviews and detailed information about the process and the current situation.
However today's information presentation means provide limited support for collaboration. Desktop monitors are limited in size both regarding the amount of information to be presented and the number of people who can look at such a screen. Large screens generally only allow limited interaction, if any interaction at all.
A typical example of a general collaboration situation is taken from the office environment where two or more people work together, e.g., on defining work packages and tasks for a project plan.
In the area of industrial process control, an international application WO 2005/114368 describes a method to manipulate data for an industrial device supervised by a control system in an industrial or commercial plant. A substantially static and easily visible large sized display member 2 is used to provide a graphical user interface for retrieving data about, and/or controlling, one or more industrial devices. The application also describes that a computing device or mobile computing device such as a PDA can send a link or URL to its GUI, or a copy of its GUI, to the large display for ease of information retrieval and access.
A primary aim of the present invention is to provide a method to control or monitor an industrial device using an improved Graphical User Interface to retrieve and display technical data for the industrial device using a computer program for control and at least one computing device running said control program at least in part, wherein said control program comprises a graphical user interface arranged capable of generating a signal to retrieve said technical data related to one or more industrial devices.
A secondary aim is to provide a system for carrying out the method, and a computer program for carrying out the method. Another aim of the invention is to provide more than one instance of a graphical user interface (GUI) for carrying out the method.
The above and more objects are achieved according to the invention by a method according independent claim 1 and a system according to independent claim 20. Preferred embodiments are described in the dependent claims.
According to a first aspect of the invention these and more aims are met by the invention in the form of a method carried out by one or more computer programs running at least in part on the computing device that enable a copy of the graphical user interface running on the computing device to be displayed on a large display screen, and data retrieved and/or manipulated by means of actions carried out in relation to the GUI displayed on the large display screen.
According to another aspect of the invention these aims are met by the invention in the form of a system.
According to another aspect of the invention an active display device arranged with an improved input device is described.
In a preferred embodiment, the active display device is arranged for cooperation with wireless communication and wireless devices.
In one aspect of the invention an improved active display device in the form of a flat and horizontal screen, arranged for example as a touch-screen, is arranged and set up as a table. An interactive table, or touch table, it is dimensioned to allow a number of people to stand or sit around it. Each participant has his own ‘home’ area in front of him on the table where personal documents and applications of the person appear. This ‘home’ area may follow the participant as the participant moves around to different parts or sides of the table. Interaction with the interactive collaboration table takes place directly as a touch screen with hands and/or with specific interaction devices. The invention was disclosed at least in part in a provisional patent application U.S. 60/851,298 filed 13 Oct. 2006, which specification is hereby incorporated in this description in full by means of this reference.
The touch table allows multiple users to interact simultaneously either on different applications/documents or at the same application/document. Each collaborator can ‘drag’ a document/application from his ‘home’ area to the main area. The interactive touch table allows basic graphic interface manipulation actions such as to move, rotate, scale, crop and zoom the interface or window of an application or of a document.
Furthermore, the content of an application or a document can be edited such as to change a set point or to acknowledge an alarm. It is important that the system identifies the person who performs such a task. The interactive touch table is particularly advantageous to use for collaboration where an application or a document, etc. is critical for the discussions and the collaboration.
The advantages include that the interactive table: is a multiple user system; has support for simultaneously multiple inputs; can be operated for natural and intuitive collaboration; every participant can contribute equally; it supports carrying out online modifications by logged on users; it supports giving information in a number of different ways (eg direct writing of text and numbers (handwritten), as well as by selecting in ‘scroll-bars’, etc.).
The invention provides a user such as an operator or an engineer with means to take a copy of display a GUI, application interface or document that may be running on a first computer, and transfer it to the interactive table for easier manipulation of the GUI, collaboration with others and for easier access to information retrievable via the GUI. Instead of examining information and/or images on a small display screen, such as a 16″ monitor or a PDA display, the user may examine information displayed on a large screen. The user may also discuss the information and/or images of a selected industrial device with other operators or engineers so as to obtain information about the equipment, solve a problem, arrange for production processes, different production batches or versions etc, maintenance for one or more devices, and so on.
The principal advantage of the invention is that technical data and other information pertaining to a selected device may be quickly and easily retrieved and displayed and manipulated. This makes testing, trouble shooting, and general supervision and/or control of selected industrial devices, automation devices, robots, power distribution devices, to be carried out in a timely manner. This has the effect of reducing both predictable delays such as production set-up times, machine configuration or planned maintenance as well as downtime due to unpredicted stoppages, problems and the like.
In a preferred embodiment of the invention the computing device comprises one or more microprocessor units or computers. The computers or servers comprise memory means for storing one or more computer programs that control the graphical user interface of the interactive table. Preferably a such computer program contains instructions for the processor to perform the method as mentioned above and described in more detail below. In one embodiment the computer program is provided on a computer readable medium or data carrier such as a CD ROM.
Embodiments of the invention will now be described, by way of example only, with particular reference to the accompanying drawings in which:
a-c are flowcharts for one or more methods according to embodiments of the invention;
A user such as an operator, engineer or technician in a factory or other installation for industrial or commercial operations wishes to retrieve and/or manipulate information about an industrial device. The user may have already activated one or more control programs of an industrial control system so as to display a part of the installation including the industrial device of interest.
According to an embodiment of the present invention, one or more programs, applications, interfaces or documents showing or handling the industrial device of interest may be selected and marked in some way, preferably by dragging a representation on a graphic user interface to a graphic device hereafter called a “widget” which acts as a basket or other container.
The user then goes to the active display device, the interactive table carrying with him or her an identification means.
a shows a flowchart for at least one method of an embodiment of the invention. A user selects one or more applications or interfaces or documents associated with an industrial device or process by, for example, dragging them on to the tool called the widget. The method comprises:
The table recognises the User ID card 50 or object 45 and displays on a home area 4a-4c the ID object and the widget. The user may then move or open an application etc on the interactive table.
b shows a flowchart for another part of a method according to an embodiment of the invention. A user at the interactive table may select one of the applications etc and move or open it on the table. The application or interface or document displayed may be resized, rotated etc. The method comprises:
Thus more than one user may manipulate an application on the interactive table. More than one user may manipulate the same application or interface at the same time.
c shows a flowchart for another part of a method according to an embodiment of the invention. A user may select a part of an interface, or a graphic object on the interface, and input a value from a scroll box or other selection means. Input may also be done by writing freestyle. Set points or other parameters may be selected and changed. Input is made via the active display means by a signal transmitted by any of IR, wireless radio, ultra sound. The pointing device or stylus 21 may have all the graphic interface functionality that a computer mouse usually has to operate graphic functions, cut, copy, paste, re-size and so on.
The method comprises:
In another preferred embodiment, the program for control of processes and industrial devices in a facility may use representations other than tree diagrams to symbolise facets of the equipment controlled. Equipment and or devices may be represented in terms of process logic, in relational diagrams, process-flow diagrams, function block schemas, flow charts or any other way for representing industrial, chemical or commercial processes. The user may then use a tree structure or a process logic structure etc to navigate within and/or between devices and processes represented in the control program to retrieve technical data about a device or a process etc.
A data connection may be established at least at first by means of a wireless network or temporary wireless network, using for example a radio technology such as Bluetooth, or an IR connection to initiate recognition of the selected display screen (workstation) and/or recognition of the PDA user. Thereafter the methods and advantages are as described. Any workstation in a plant may be used, so long as there is means to identify the workstation, and any kind of computer controlled display device may be used, including a fixed workstation, portable computer or laptop, notebook etc or even suitably equipped telephone, provided that it is connected to a display that can provide a GUI.
Suitably low-energy transmissions compatible with explosion-proof standards for use, for example, by a painting robot, may be made using a short-range radio communication, such as a low-energy transmission conforming to a protocol compatible with any of: standards issued by the Bluetooth Special Interest Group (SIG); any variation of IEEE-802.11, WiFi, Ultra Wide Band (UWB), ZigBee or IEEE-802.15.4, IEEE-802.13 or equivalent or similar. A standard compatible with WAPI (WLAN Authentication and Privacy Infrastructure, GB15629.11-2003 or later) may advantageously be used in situations where encryption of the wireless signal is necessary or advantageous. Generally a radio technology working at high frequencies usually greater than 400 MHz, for example in the ISM band or higher, with significant interference suppression means by spread spectrum technology is the preferred type of wireless communication. Wireless communication may alternatively be carried out using Infra Red (IR) means and protocols such as IrDA, IrCOMM or similar. Wireless communication may also be carried out using sound or ultrasound transducers.
One or more microprocessors (or processors or computers) comprise a central processing unit CPU performing the steps of the methods according to one or more aspects of the invention, as described for example with reference to
The computer program comprises computer program code elements or software code portions that make the computer or processor perform the methods using equations, algorithms, data, stored values, calculations and statistical or pattern recognition methods previously described, for example in relation to
It should be noted that while the above describes exemplifying embodiments of the invention, there are several variations and modifications which may be made to the disclosed solution without departing from the scope of the present invention as defined in the appended claims.
