Abstract

The invention relates to a device for status inquiry of mechanically / electrically recognizable switching states or switching positions in the context of inspection and infrastructure monitoring.
According to the invention, transponders, which are designed in particular passively, or comparable components for the radio-capable status inquiry of mechanically / electrically recognizable switching states or positions as well as end positions in the context of inspection and infrastructure monitoring are attached to switching elements or corresponding components.
Depending on the assumed position of the switching or adjusting elements, the transponder function is activated or deactivated in which, for example, the electrical connection of the transponder unit with the transmitting part is "looped" via the switch contact to be monitored or via a slide element upon reaching a mechanical target position, eg end position the electrical function of the transponder is activated, for example by closing an electrical connection and thus the state can be queried by radio. Advantageously, by using differently coded transponder units also diverse switching and desired positions can be detected in a switching or control element.

Description

The The invention relates to a device for status inquiry of mechanical / electrical recognizable switching states or switch positions within the framework of inspection and infrastructure monitoring.

The review or the determination of the proper function of many components of infrastructure conditional the review of switching states or reaching / maintaining defined mechanical positions, in particular end positions and positions of switching elements.

Often conditional this review in Prior art opening corresponding devices or extensive wiring measures for diagnostics. So In particular, the final states of Switches provided with contact switches, which when reaching the respective final state are activated. About appropriate cable will the output from the contact switch signal to an evaluation forwarded.

Of Further state of the art are so-called overhead line mast switches or pole disconnect switch for switching on and off individual overhead line sections for electrically operated railways. Switch these trolley mast switches streams between 1000 A and 2000 A and are for local operation with manual operation or for set up a remote control. In the version "Local control with manual operation" the trolley mast switch is used through a hand lever over a linkage switched, the position of the hand lever, the position of the trolley mast switch reproduces. In case of damage the mechanics of the linkage or the overhead line switch, however, gives the position of Hand lever not the true circuit state of the trolley mast switch again. Therefore, in this case, the trolley mast switch in addition by an operator to be visually inspected.

Out DE 102 58 919 A1 a device for switching position signaling of a switching device is known in which an attachable to the switching device and connected thereto via a coupling device accessory has one or more radio-readable transponder and an antenna, so there by information from the transponders from the inside of the accessory from a place outside of the additional device can be queried wirelessly.

It It is therefore an object of the invention to provide a device with a status inquiry of mechanically / electrically recognizable switching states or positions, in particular in the context of inspection and infrastructure monitoring fast and without big ones Effort possible becomes.

These The object is in connection with the preamble of claim 1 according to the invention the features specified in claim 1 solved.

The under claims include advantageous embodiments the solution of the invention Claim 1.

According to the invention are Switching elements or corresponding components transponder, in particular passively executed are, or comparable components to the funkabfragbaren state query of mechanically / electrically recognizable switching states or positions as well as Final positions within the framework of inspection and infrastructure monitoring appropriate.

Depending on the borrowed position of the switching or adjusting elements is the Transponder function is activated or deactivated by e.g. the electrical Connection of the transponder unit with the transmitting part via the to be monitored Switching contact is "looped" or over Slider element upon reaching a mechanical set position, e.g. End position the electrical function of the transponder, e.g. by closing one electrical connection is activated and thus the condition per Radio can be queried. Advantageously, by using different coded transponder units also varied switching and set positions be detected in a switching or actuating element.

The Transmitting part is designed in particular as a passive element, the not at reference potential. This has the particular advantage that the device according to the invention can also be used in the high voltage range. The switching state can be so -. at Inspections - about one small, on the outside of the case attached antenna can be interrogated and checked by radio.

transponder In this case, passive elements in particular are activated via suitable radio signals and return coded information if necessary. They are beneficial very small (mm to cm) and inexpensive to produce (cent range in large quantities).

When entering or driving on routes whose infrastructure contains correspondingly equipped switching elements, the transponders are activated via a carried simple transmission system and read out the mechanically / electrically recognizable switching state or the switching position characterizing associated data / information. The read-out data / information is the basis for a fast, simple and secure automatic Addition of detected findings to the respective technical places of the infrastructure.

advantage The invention is that the effort for inspection and maintenance significantly lower and achieve significantly higher data quality leaves.

Especially Advantageous are passive transponder systems, in particular RFIDs (Radio Frequency Identification), as used e.g. for localization of goods in the field of logistics.

to Determination of the mechanically / electrically recognizable switching state or the position of the actuating element drives a vehicle (inspection / maintenance vehicle, Lok, Regelzug) with a tuned to the transponder or its resonant frequency Transmitter and receiver unit from the route network. In the places where a transponder unit is attached, is targeted by Transponder issued a response signal. Thus, the corresponding Switch located and can the mechanically / electrically recognizable Switching state or the position of the actuating element can be determined.

The Application of the device according to the invention However, it is not limited to rail systems only. Much more can she for all Types of vehicles are used on specified route networks and thus at certain specified locations within the Pass the route network.

The Invention will be explained in more detail with reference to an embodiment.

In the particularly advantageous embodiment transponders are attached to switches along the way. One Vehicle with a tuned to the transponder or its resonant frequency Transmitting and receiving unit moves along the corresponding section of the route. At the point where one Transponder attached to a switch is targeted by the Transponder issued a response signal whose coded information content depends on the currently assumed switching position. Thus, the location is localized and can the mechanically / electrically recognizable switching state or the Setting position of a control element can be determined.
