The conventional setup of a conveyor system is such that there is a conveyor means (e.g. Conveyorcage, skip or counter-weight) attached to the ends of the upper cables. By moving of the upper cable with the help of the driving disc, the conveyor means is moved through the shaft.
Depending on the respective depth of the conveyor means, i.e. The length of the upper cables in the shaft, there may be different cable forces among the upper cables. These differences must be balanced out to warrant an even carrying capacity and thus even strain of the upper cables. Additionally, a transmitter module can be provided on the conveyor means that comprises at least one transmission antenna for wireless transmission of the measured cable load values to the surface, and to which the cable load measuring element or the independent cable load measuring elements are connected.
The transmitter module may also comprise an interface, possibly in the form of an additional close-range antenna, a USB interface, a Bluetooth interface or an infrared interface in order to be also able to provide the measured cable load values to a receiver that is disposed within the conveyor means, as in the case of a laptop computer, a handheld or the like. The cable load measuring elements 6 are connected to a transmitter module 8, with each cable load measuring element 6 having a separate and dedicated connection to the transmitter module 8. The transmitter module 8 is connected to an antenna 10 on the conveyor means, which can transmit the read values of the cable load measuring elements 6 by radio transmission to a corresponding antenna 14 to a receiver 12 that is located at the upper end of the shaft. The transmitter module has six channels so that, in case of a number of more than six upper cables and therefore accordingly many cable load measuring elements, a correspondingly larger number of transmitter modules 8 must be provided. In the embodiment, as displayed in the figure, the measured cable load values as received by the receiver 12 are in turn transmitted by radio transmission to an additional receiver 16, which is connected to an evaluation system 18, for calculation of the differences in the cable loads and illustration of the correction values for the cable length and/or the cable grooves of a cable carrier.
The receiver 16 can therein also receive the measured values of more than one transmitter module 8. For the receiver 16 to be able to process more than the six channels of one transmitter module 8, each transmitter module 6 sends an ID before transmission of the six measured values so that the receiver can assign the transmitted measured values to the respective transmitter module 6.
If there are several transmitter modules 6, the transmission of the respective six measured values then takes place sequentially, i.e. One transmitter module after the other.
The device according to claim 9, wherein the cable load measuring elements are integrated into an cable attachment.

Description A complete hands-on guide to designing and implementing all types of telecommunications transmission systems. For more than 23 years, Telecommunications Transmission Handbook has been the guide to designing and building telecommunications transmission systems and the reference of choice among a generation of communications engineers and technicians. Its total systems approach examines each telecommunications transmission specialty as an integral part of a larger system.
This book constructs a framework for understanding and exploiting the ways in which each telecommunications specialty affects all the others. It provides:.
Clear, methodical delineation of key principles, theories, and concepts. Lucid explanations of cutting-edge design methodologies. Comprehensive coverage of new and emerging technologies. Step-by-step instructions on how to design and implement all types of telecommunications links, systems, and subsystems. Following in this tradition, this Fourth Edition is fully updated to include coverage of important recent developments in telephone transmission, digital networks, microwave systems, radio systems, VSAT networks, meteor burst communication, fiber optics, and more.
It also features entirely new chapters on cellular and wireless communication systems, cable and digital television, and low Earth-orbiting satellites. A senior life member of the IEEE, Roger Freeman has lectured at numerous professional conferences and published widely in international telecommunications journals. He gives telecommunications seminars at the University of Wisconsin, Madison.
