Problems solved by technology

The operation of continuous transmission leads to the permanent transmission of high-frequency radio frequency pulses in a limited frequency band, which can lead, for example, to storage rooms of many industrial vehicles equipped in this way, especially in the case of two or more transceiver units at the same time some problems in operation

Embodiment Construction

[0028]In FIG. 1 , a vehicle data bus is indicated at 10 . The vehicle data bus 10 is a CAN bus via which all electronic circuit units connected to it can exchange data with each other quickly, simply and securely. The data is sent via the data bus in the form of telegrams.

[0029] In the industrial vehicle according to the invention, the RFID transceiving unit 12 is provided with a suitable interface 13 which is directly connected to the vehicle data bus 10 . The RFID transceiving unit 12 includes an antenna not shown. Furthermore, in an embodiment of the illustrated embodiment, the RFID analysis unit 14 is connected to the vehicle data bus 10 in a discrete module manner.

[0030] The RFID transceiving unit 12 converts the signals received from the transponders into telegrams and transmits the telegrams via the vehicle data bus 10 to the RFID evaluation unit 14 . The RFID analysis unit 14 receives the telegram and analyzes the data contained therein, the data being receive...

Abstract

An industrial truck with a send and receive telegram and a data bus, to which several electronic units of the industrial truck are connected which send or receive telegrams via the data bus, and with a sending and receiving unit which can acquire data of a transponder present in the sending and receiving range of the sending and receiving unit, wherein the sending and receiving unit is connected to the data bus and analyses telegrams sent via the data bus and / or sends telegrams to the data bus.

Description

technical field [0001] The invention relates to an industrial vehicle equipped with a data bus and a transceiver unit. Background technique [0002] Modern industrial vehicles are equipped with many electronic circuit units. In particular, drive control for controlling the drive motor, lift control for controlling the lift function via the hydraulic system, an on-board computer, and various elements that both control and operate are among these electronic circuit units. In operation, many of these units exchange data with each other, for example, the lift control transmits the control commands of the operating elements to the drive control, or sends condition information related to the lift action to the on-board computer. [0003] For such communication processes, a vehicle data bus is usually provided for connecting electronic circuit units and for communication via so-called telegrams. A bus system frequently used in the field of industrial vehicles is the so-called CAN...
