Description

Transport device and system for locating one or more

transport equipment

The invention relates to a transport device for the transport of goods, in particular general cargo, with at least two,

preferably at least three rollers. Especially

The invention relates to a system for locating one or more such transport devices.

Systems for locating moving objects are known. Among the known positioning systems is the satellite-based Global Positioning System (GPS), which is available worldwide. Furthermore, position determinations can be carried out by means of GSM localization, which is the locating of a switched-on GSM terminal (mobile system) based on GSM (Global System for Mobile Communications) via a mobile radio network.

In the field of transport logistics RFID systems are often used today for the automatic identification and localization of objects. An RFID system consists of a transponder, which is located on or in an object to be detected and contains a distinctive code, and a reader for reading the code. RFID transponders can be realized in tiny dimensions. The structure of an RFID transponder essentially comprises an antenna, an analogue circuit for receiving and transmitting, as well as a circuit (microchip) and a permanent memory. For communication with the RFID transponder, the reader generates a high-frequency electromagnetic alternating field, to which the transponder is exposed. The high frequency energy absorbed by him via his antenna converts the

Transponder into electricity supplied to its microchip. With active RFID transponders, the power can also be provided by a built-in battery. The so

activated microchip of the RFID transponder decodes the commands sent by the reader. His answer encodes and modulates the RFID transponder in the irradiated

electromagnetic field by weakening the field emitted by the reader. Thus, the RFID transponder transmits its own code, other data of the marked

Object or other information requested by the reader. The RFID transponder thus does not generate itself

electromagnetic field, but affects the electromagnetic field of the reading device.

For determining the position of transport vehicles RFID systems have been developed in which the respective position with the help of at a small distance from each other in the ground

arranged RFID transponders is determined on the basis of their known position on the code read and interpolation. However, such RFID systems are of it

depending on the fact that only previously determined routes are traveled. As soon as the vehicle leaves the predefined route, the system is ineffective.

The present invention has for its object to provide a transport device of the type mentioned, which can be conveniently and reliably located in a large geographical area, preferably nationwide or even worldwide. This object is achieved by a transport device having the features of claim 1.

The transport device according to the invention has at least two, preferably at least three rollers. At least one of the rollers is provided with an electronic locating device which has a GPS module and / or mobile radio module for transmitting locating signals, a dynamo-functioning generator and an energy storage. The generator and the

Energy stores are coupled together by a charging unit. The generator is in the caster

integrated, while the GPS module and / or the mobile radio module in the roller and / or on a holder in which the roller is rotatably mounted, is integrated or are.

The transport device according to the invention, which can be designed in particular as a roll container, handcart or dolly for piece goods, thus has a hidden or

inconspicuous, self-sufficient in terms of power supply

functioning device for transmitting signals covering a reliable and convenient location of the transport device in a large geographical area nationwide

allows. Due to the hidden arrangement of the generator, the energy storage device, the charging unit, the mobile radio or GPS module in the roller or on a holder in which the roller is rotatably mounted, the greatest possible protection of these components against vandalism can be achieved. The energy store is expediently from a rechargeable battery (accumulator) and / or a

Double layer capacitor formed. A preferred embodiment of the invention provides that the generator is provided with a voltage limiter.

The voltage limiter prevents overcharging of the energy store. The voltage limiter is preferably connected upstream of the charging unit assigned to the energy store or integrated in the charging unit.

A further preferred embodiment of the invention is characterized in that the holder, in which the roller containing the generator is rotatably mounted, comprises a leg connected to the axis of the roller, which has a concavity in its side facing away from the roller, in which the GPS -Module and / or the mobile module, the energy storage and / or the charging unit are arranged protected. The holder can do this

typically made of sheet steel and formed fork-shaped. The arranged in the concavity

Components, namely the GPS module, the mobile radio module, the energy storage and / or the charging unit are thus sufficiently protected in the normal case from impacting or colliding objects. The indentation also causes a stiffening of the holder.

Another advantageous embodiment of the invention is characterized in that the holder, in which the roller containing the generator is rotatably mounted, comprises a leg connected to the axis of the roller, on whose side facing the roller the GPS module and / or the mobile radio module, the energy storage and / or the charging unit are arranged protected. With this variant, a particularly effective protection of the electronic components of the locating device is provided
