摘要： A cable including an integrated intelligent cable module. The module preferably includes an integral instrument package. The instrument package may assume many forms and may serve many purposes. In a preferred embodiment, the module includes a position-determining system and an on-board processor. The processor determines a current location in space for the module based on the information it is receiving. This positional information may then be transmitted to an external receiver. The module also preferably includes load-monitoring and recording features. These features act as a “black box” for the cable, monitoring its performance and reporting (in real-time or at a later time) any exceedances or any deterioration in performance or structural integrity.

摘要： A cable barrier system is managed by a cable barrier management system including a management system controller having a management processor, a wireless data communications interface, and a plurality of turnbuckle subsystems configured to be joined to respective barrier cables to provide pretension. Each of the turnbuckle subsystems has a strain gauge mounting zone and is configured to enable communication of strain from a strain gauge circuit to the management processor. The management system controller includes a sensing circuit to receive the strain gauge output voltage from the strain gauge circuit and provide sensing circuit output to the management processor. The management system controller includes a cable barrier analysis module configured to determine excess strain events. The management processor generates strain event data, which is sent via the wireless data communications interface to a remote recipient computing device.

摘要： A system for monitoring the state of a cable, which is guided in an energy chain between a base and a movable driver element. The movable energy chain forms a movable run at a driver element, a resting run at a base and, between the two runs, a deflecting bend. A monitoring device having at least one indicating element at the energy chain evaluates an indicating-element signal and monitors whether an error state occurs. The indicating element has two electrical indicating conductors guided by the energy chain, which indicating conductors extend along the movable run, and the monitoring device comprises a measuring circuit for resistance measurement or conductance measurement. One end point of each indicating conductor is connected to the measuring circuit and the other end points of the indicating conductors are short circuited such that the indicating conductors form a measurement loop.

摘要： The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.

摘要： Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.
