摘要:
The invention concerns an intelligent electronic device as well as a method for activating a function in an intelligent electronic device. The device (12) includes an inter-module bus (26), a first interface (30) and a number of hardware modules (18, 20, 22, 24) connected to each other via the inter-module bus (26). The modules include a process control module (18) including a control unit that senses the types (T1, T2, T3, T4) of hardware modules connected to the inter-module bus, that obtains set-up data from an external portable data carrier, where the set-up data includes configuration data and verification data, where the verification data includes hardware type data related to the modules in the device, that compares the obtained verification data with own verification data including data regarding the sensed hardware type, and that activates a protection function only if there is a match between all verification data being compared.
摘要:
The manipulator according to the invention exhibits an improved structure since the communication between the main controller (1) in the remote unit and the controllers (7) in the workplace unit is performed via a wireless communication channel (12) which is preferably a radio channel. Accordingly, no cables are required to connect the main controller (1) and the control units (7) for communication purposes. However, the controllers (7) of the manipulator according to the invention are connected to encoders (6) or resolvers (6) to receive information about the actual position of the controlled manipulator axis (N). Further, the controllers (7) of a manipulator according to the invention are connected to drivers (5) for supplying power to the motors (3) causing the movement of the manipulator. Thus, the controller performs the control of the manipulator movements in a direct and local manner, however, being remotely controlled by the main controller via a wireless communication channel.
摘要:
The invention is a method for changing a tool (12) for a robot or manipulator (5) comprising a wireless communication device (14) for control and/or data communication on the tool (12). Communication or control cables are not necessary between the robot arm (5) and the moveable robot tool (12). The one or more wireless communication members (14) comprised on the robot tool may also be powered by the contactless power supply in another embodiment. In other aspects of the invention a system, and a computer program for carrying out the method are described.
摘要:
The invention concerns an electrical process interface device for provision in a low control and protection level of a Substation Automation or Distribution Automation system. The device (16) includes a process interface unit (26) for interfacing the electrical process at the low control and protection level, which unit has a number of parallel data connections on which I/O data related to control and protective devices on higher control and protection levels may be transmitted. The device (16) also includes a signal conversion unit (24) connected to the data connections, which unit packets data of the data connections according to a communication standard used by control and protective devices on the at least one higher control and protection level for allowing data to be directly transmitted between the electrical interface device (16) on the low control and protection level and other devices on higher control and protection levels.
摘要:
The invention concerns an intelligent.electronic device for a Substation Automation or Distribution Automation system as well as to a method and computer program product for providing it. The device (14) has a structuring of its own functionality according to a communication standard and comprises mechanically separable, replaceable hardware modules (26, 28, 30, 32, 34, 36, 38) interconnected via an inter-module bus (40). The modules implement functionality related to function related elements of the standard and include a communication module (28) and I/O modules (32, 34, 36, 38). The device (14) includes elements of the communication standard comprising one device related element and replaceable function related elements of all the functions provided by the modules. The communication module (28) includes the device related element and function elements associated with the function of the communication module as well as functions provided by all the I/O modules (32, 34, 36, 38).
摘要:
The invention is a die (22b) for an industrial press (1) arranged with a wireless communication device (14) and a contactless power supply (10,12). Power and/or control cables are not necessary between a stationary press (1) and the die (22b) or other moving part arranged with the press (1). One or more sensors on the moving part of the die (22b) may be contactlessly powered and wirelessly controlled. The wireless communication member (14) of the die (22b) may transmit data from one or more sensors on the die (22b) to a press control unit (24) or other control unit (25). The power supply (10,12) includes a primary power supply member (2,8) and secondary power supply member (13,15). In other aspects of the invention a method and a system are described.
