Definitions

  • the invention relates to a base, in particular a relay base, comprising a mounting area for the detachable mounting of the base on a top-hat rail, a receptacle for an electrical and / or electronic component, in particular a relay or a contactor, the base at least two electronic connections for comprises the electrical and / or electronic module, and wherein the base comprises at least two connection contacts, each connected to one of the electronic connections.
  • Sockets for an electrical and / or electronic component in particular, for example, electromechanical switching elements, are known in many ways.
  • Such bases are devices to quickly attach and detach replaceable switching elements.
  • Such bases serve, for example, in the form of plug-in sockets as receptacles for relays, contactors, transistors and / or integrated circuits.
  • a relay socket typically comprises at least two connection terminals for the control circuit and two further connection terminals for the load circuit. These can be designed as screw terminals, tension spring terminals or leg spring terminals, etc., for example. If the base is only used for one contactor, two connection terminals are sufficient.
  • a relay thus essentially comprises two electrical connections for the control circuit and two or three electrical connections for the load circuit.
  • a relay socket is disclosed, for example, in EP 1 052 731 B1 (Weidmüller Interface GmbH).
  • a clamping body comprises latching means for latching the clamping body onto a mounting rail.
  • the clamping body comprises an essentially right-angled recess into which a relay module can be inserted.
  • the relay module is fixed to the clamping body by an essentially U-shaped swivel bracket, which has two longitudinal legs and a base leg aligned at right angles to the two longitudinal legs.
  • the clamping body is provided on its upper side with several pairs of connection openings for connecting external conductors.
  • Relay sockets for mounting on a mounting rail.
  • Relay sockets have been known for many years and are largely standardized mass products.
  • Such relay bases are typically mounted in control cabinets on mounting rails or top hat rails and are used in particular to control machines, industrial systems, building services, etc.
  • Relays especially electromechanical relays, generally have a limited service life. If a relay fails, the installation controlled by it stands still until the relay is replaced. On the other hand, the relays could also be replaced at regular intervals, but relays are removed that might have worked for a long time. Presentation of the invention
  • the object of the invention is to create a socket for an electrical and / or electronic module belonging to the technical field mentioned at the beginning, with which a downtime caused by the exchange of a module can be reduced.
  • the base comprises a detection device for detecting a first value of a parameter of the electrical and / or electronic component.
  • the base includes a mounting area for mounting the base on a top-hat rail.
  • Such assembly areas are familiar to the person skilled in the art, in particular from the area of relay sockets in different variants.
  • the assembly area comprises at least one snap hook which can engage behind a flank of a top-hat rail.
  • the base can, for example, be hooked into the top-hat rail from one side with an undercut and attached to the top-hat rail on the other side by means of a latching element which engages behind the top-hat rail.
  • the person skilled in the art is also familiar with other types of fastening which are suitable for detachable mounting of the base on a top-hat rail.
  • the base comprises at least two electronic connections for the electrical and / or electronic module.
  • a fuse or a relay can be electrically connected to the base as a component.
  • the base in turn comprises at least two connection contacts which are connected to the electronic connections.
  • a load circuit and / or a control circuit can thus be connected to the at least two electronic connections via the connection contacts.
  • the electronic connections can be designed, for example, as sockets, plugs or the like.
  • the connection contacts can be designed, for example, as sockets, plugs, terminals or the like. Further possibilities are known to those skilled in the art, in order to establish an electrical connection between To create connecting wires or the like and the base and between the base and the module.
  • a first value of the parameter is recorded with a detection device of the base.
  • replacing a component that has already failed will take considerably more time than replacing a (still) functioning component.
  • the block is defective. This does not necessarily have to be trivial because, for example, in the case of a control of individual motors, their circuit breakers or the motor itself can be defective.
  • After identification it must be checked whether a corresponding component is available on site as a replacement - procuring a new component of this type can also take a long time.
  • the module also has to be replaced. For this, for example in a company, a responsible person must be present. In the event of an unplanned failure of a module, a lot of time can be lost until it is replaced. This can lead to a production standstill in a production facility, which can result in high costs.
  • the acquisition device for the values of the parameter of the module to be acquired is now arranged in the base.
  • the detection device can thus be used multiple times, regardless of whether a module has to be replaced multiple times.
  • the detection device can also be designed largely independently of the module, so that the same detection device can be used for several different modules.
  • the first value is preferably used to decide whether the module fulfills a predetermined criterion of the parameter.
  • the value itself can allow conclusions to be drawn about the function of the component, so that, for example, it can be determined whether the component is defective or is functioning properly. In order to be able to make such an assessment, it can be useful to determine several values of the parameter or also several values of different parameters over a period of time. In variants, the value can only be used for statistical evaluations, so that the individual value itself is not used to check a criterion.
  • the value can, for example, be a single switching cycle that is added up by a processor or counter. In this case, the criterion of the parameter can represent the achievement of a total number of switching cycles, while the value is always 1 (increment). On the other hand, the value can also include the switching cycles totaled in the base itself.
  • the first value is preferably used to calculate a service life of the module.
  • a value of a parameter in particular a parameter which is decisive for the service life of the module, can now be used in order to estimate the remaining expected service life of the module.
  • the replacement of the module can be planned in such a way that the risk of failure of the module can be weighed against the service life.
  • the module can be replaced after 90% of the average expected service life in order to keep the risk of failure of the module below 0.1%, for example.
  • the failure of the system to be controlled can be kept to a minimum.
  • the module can be replaced, for example, during maintenance phases or breaks, etc., so that operation does not have to be interrupted.
  • the parameter can in principle be one-dimensional; in particular, it can only be used to count the switching processes, for example.
  • the parameter can also be present as a multidimensional vector, whereby, for example, a time can be assigned to a value of the switching cycle, a further value of another parameter, for example a switching time, a maximum current, etc. can be assigned.
  • a base is understood to mean a device on which the electrical and / or electronic component can be connected to the electrical contacts of the base. Signals and / or energy can be transported via the electrical contacts.
  • the base is a base for relay and / or contactor. This is particularly preferably a relay socket. Both electromechanical relays and semiconductor relays or other relay types known to those skilled in the art can be provided as relays. To the However, it is clear to a person skilled in the art that other bases can also be provided on which other electronic and / or electrical components can be arranged, for example a fuse, a lamp, etc.
  • the base is particularly preferably designed to accommodate precisely one module, so that each module is assigned its own base.
  • the relay base is designed to accommodate precisely one relay or precisely one contactor.
  • the base can also be designed in such a way that two or more modules can be accommodated.
  • the base comprises the detection device.
  • a value of a parameter of the module is determined.
  • the relay can be monitored with the detection device. For this purpose, for example, the functionality of the relay, an expected service life, etc. can be determined.
  • the parameter comprises a switching cycle of the electrical and / or electronic module. This means that the number of switchings made by the relay can be determined and monitored.
  • the switching cycle refers to the complete change of a switching state in an electrical switch back to the starting position.
  • the term "switching cycle” is a synonym for the term "switching cycle”.
  • the service life is closely linked to the number of switching operations carried out. The more switching operations that have been carried out with a relay, the shorter the remaining service life is typically. Because the number of switching processes or the switching cycle is determined by the detection device, a conclusion can be drawn about the average remaining service life of the module or the relay. For example, when a threshold for the number of switching operations is reached, a message can be issued that the module or relay needs to be replaced. In this way, an uncontrolled failure of the module or the relay can be counteracted preventively. In variants, it is also possible to dispense with determining the switching cycle. It is also clear to the person skilled in the art that values of further parameters can be recorded and processed (see below).
  • the threshold for the number of switching processes can be selected, for example, in such a way that a balance is drawn between the risk of failure and the service life of the module.
  • the risk of failure can also be minimized by replacing the module, for example, after half the expected service life. This can be provided, for example, in the case of security-relevant systems, such as alarm systems, operating devices in hospitals, etc.
  • a countdown can be set up with the detection direction, which subtracts the switching cycles carried out from the mean maximum number of switching cycles and when the maximum number of switching cycles is reached of a proportion, for example 95% of the maximum number of switching cycles, a message is output that the module needs to be replaced.
  • the values of the parameter are preferably collected and evaluated centrally from a plurality of bases.
  • the collection of the values of the parameter can, for example, be handled in a cloud-based manner, in particular through file hosting or file sharing. This means that the data can be called up particularly easily regardless of location.
  • the data can thus also be received via a mobile receiving device, in particular a tablet or a mobile phone (smartphone).
  • the values of the parameter can also only be saved and handled locally.

  • the detection device preferably comprises a counter for counting the switching cycle of the electrical and / or electronic component.
  • a number of switching operations can be queried, especially in the case of the base itself, and a message can be output if the number exceeds a limit value.

  • the detection device and / or the transmission device is preferably designed to detect one or more of the following parameters of the electrical and / or electronic component: switching state, switching time, voltage, voltage profile, current, current profile, resistance, temperature. One or more of these parameters are preferably recorded in the method.
  • the switching status can be used to check whether the module, in particular the relay, is working.
  • a load circuit or the like can be monitored and compared with the switching processes.
  • the switching processes can also be used for a later analysis of the controlled systems. In particular, troubleshooting in a company can thus be optimized.
  • the following parameters can also be used for this purpose.
  • the switching time can be used to monitor whether the module is working constantly. If the switching time is changed, for example, conclusions can be drawn about the remaining service life.
