  • the invention relates to a method for switching range control of a non-contact SehaltSystem with at least one sensor and at least one signal generator, wherein the sensor receives data from the signal generator. Furthermore, the invention relates to such a sensor and such a contactless switching system.
  • Such a switching system or a method for switching range control is used in the private and in the industrial sector.
  • the switching system has the function to detect entry and stay of a signal generator within an effective range of the switching system and then to report the event, for example, or to trigger an on, off, or protection switching operation.
  • the triggering usually takes place when the carrier of the signal transmitter is detected within the effective range or detected for a certain period of time within this effective range or no longer detected.
  • the carrier is a mobile unit, which is to be made recognizable or traceable with the signal transmitter for a sensor.
  • the safety door (barrier) of a press can be equipped with such a switching system, so that when opening the door, which carries a signal generator, it is ensured that the press can not generate any pressure.
  • the non-contact switching system thus prevents the activation of the press, as long as persons or objects are in the danger zone.
  • a non-contact switching system is usually designed as a position or safety switch, which consists of at least two independently movable parts, the sensor and the sig- dealer.
  • the sensor communicates with the signal transmitter, for example by means of magnetic or electromagnetic alternating fields.

  • the transmission of any code is sufficient, but in practice the use of a serial number, a checksum and also a freely programmable portion has prevailed within the code.

  • Position or safety switch provided to release the safety-relevant effective range only when the signal transmitter is relative to the sensor within a defined switching range.
  • Effective ranges of the position or safety switch can have very complicated, three-dimensional shapes in practice.
  • the shape of the effective range depends on the immediate environment, as well as transmission technical parameters, such as the antenna from.
  • Switch-on range In the immediate vicinity of the sensor itself is the switch-on range, which is encompassed by the so-called hysteresis range. The hysteresis area in turn is covered by the switch-off area.
  • the necessity of this distinction of the three switching ranges is due to a continuous drop of the transmission power with the distance to the sensor. Taking account of the tolerances, it is thus possible to specify mutually delimited switching ranges.
  • the switching ranges are predetermined by numerous system parameters. It should be noted that the switch-on range is separated from the switch-off range by the hysteresis range. Within this range, no switching can take place, as no reliable detection is possible. Thus, for example, a signal transmitter or its carrier must enter the switch-on range through the hysteresis range from the switch-off region before a switch-on can be triggered.
  • a position monitoring device for detecting the position of a first part relative to a second part is known.
  • the monitoring is accomplished with a transceiver attached to the first part and a transponder attached to the second part, wherein the position limit distance can be changed by means of a movable shield.
  • a disadvantage is that it is not possible to identify several switch-on areas and / or switch-off areas.
  • switch-on state So far, only two states of the system are possible, for example a switch-on state and a switch-off state.
  • the user is required to tolerate the predefined switch-on and switch-off ranges determined by the system parameters and tolerances of the device and to select the appropriate switching system or systems for its application. This is a very cumbersome and expensive procedure.
  • the invention is based on the object, a non-contact
  • This object is achieved in a method of the type mentioned in that is derived by changing at least one transmission parameter of the switching system, at least a first information on the position of the signal generator.
  • the object is further achieved by a corresponding sensor and a corresponding, non-contact SehaltSystem, each of which is provided by means of a change of at least one transmission parameter for deriving at least a first information on the position of the signal generator.
  • a switching system with at least one sensor and at least one signal generator is necessary, the signal transmitter sending data in response to a request sent by the sensor.
  • the transmitted data of the signal generator are analyzed. Since a change in the transmission parameter causes a change in the range of the effective range, a first information on the position of the signal generator can be derived on the basis of the data. If it is assumed that the effective range is known for a specific transmission parameter combination or for a specific value of a transmission parameter, it can be concluded from correctly received data of the signal transmitter that this is located in the switching range corresponding to the transmission parameter. If the signal from the signal generator is not received or received in an unsatisfactory manner, the signal transmitter is no longer in the safe switching range.
  • a distance range relative to the sensor in which the signal transmitter is located can be specified. If one assumes, for example, a circular shape of the effective range of the sensor, then the area in which the signal transmitter is located would always correspond to a ring with an inner radius and an outer radius, wherein the inner and outer radius can be assigned to effective ranges of different transmission parameters, and When data corresponding to the inner radius of action data received in accordance with operating and can not be received in a satisfactory manner at the outer radius corresponding effective range.

  • the sampling rate depends on the possible speed of the carrier or signal generator.
  • the data responses for any effective ranges are queried regularly for specific times.
  • An advantageous embodiment has a movable or mobile carrier of at least one signal generator. This results in at least two advantageous applications:
  • a carrier which has a certain extent, with, for example, two signal transmitters.
  • the signal generators can be separately detected according to the invention or their movements can be tracked. Consequently, it can be detected that a signal transmitter leaves or enters the switching range, such as the switch-on range, during the movement. This ensures that the orientation of the carrier is known. Consequently, the system is able, depending on a certain orientation of the carrier to bring about a designated switching state.
  • the switching system is able, on the basis of the data received or not received by the signal generators, to provide first information about the position of both signal transmitters.
  • the signal transmitters are set in this example such that the corresponding hysteresis ranges do not overlap each other.
  • the attachment of two signal transmitters saves the repeated request of the sensor at the signal generators, since the two responses correspond to the data of a single signal generator, which is queried with different transmission parameters.
  • the first information on the position of the signal generator is derived in a timely manner. This makes it possible, for example, to track the movement of the carrier of the two signal transmitters.
  • Advantageous embodiments include different ways of changing the transmission parameter (s). For example, a step change is useful if very specific areas are of interest. These areas can be classified with a predefined range of send parameter values. Here, for example, one can weigh between the precision of the first information about the position and the speed of the query. It is also advantageous to ensure a continuous query, for example if the switching system has detected no signal generator and is waiting for a possible switching range entry of such. Furthermore, a continuous transmission parameter change makes sense if a high resolution with regard to the position of the signal generator is desired.
  • Transmission parameters are parameters of the transmitting units, that is to say of the signal transmitter and / or optionally of the sensor, which are suitable for influencing the remote transmission by regulating the respective transmitter.

  • a further transmission parameter represents the time duration that can be measured between the request and the data arriving from the signal generator. Since the period of time from the activation of the signal generator to the correct reception of the signal generator data on the sensor depends on the distance of the signal generator from the sensor, the distance can therefore be deduced. This transmission parameter of the switching system is therefore dependent on both the sensor and the signal generator.

As a consequence, the definable switch-on ranges can only lie within the maximum possible effective range, but can be defined in their respective extent. At least one switch-off area can also be defined within the maximum effective range. Furthermore, it can be determined, for example by means of a value table of the transmission parameter provided for the change, at which point within the maximum effective range switching on or off ranges are defined. Here, the number of on and off ranges is not set. In particular, it is possible to define a switch-off range in the immediate vicinity of the sensor.
