Embodiment Construction
[0029]The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0030] The schematic block diagram of the monitoring system of the present invention is as follows: figure 1 shown. The tension monitoring and early warning system of the contact line of the railway catenary bearing cable includes a tension acquisition device 1 , a data center station 2 and a monitoring terminal 3 . The tension collecting device 1 includes a side-pressure tension sensor 110, a microprocessor module 120, a power module 130 and a device structure casing 140, such as figure 2 shown. The microprocessor module 120 includes a transmitter 121, a single-chip microcomputer 122, a power switch circuit 123 and a GPRS wireless communication module 124, such as Figure 4 shown. The side pressure type tension sensor 110 converts the shear force of the tension cable (or contact line) into a vertical force and outputs an electrical...

The invention relates to an online monitoring and pre-warning system and method for the tension of a carrier cable or contact wire of a railway catenary. The monitoring system comprises a tension collection device, a data center station and a monitoring terminal, wherein the tension collection device comprises a lateral pressure tension sensor, a microprocessor module, a power module and a devicestructure housing; and the tension collection device is arranged on the carrier cable (or contact wire) of the catenary, and can directly obtain a tension value of the carrier cable (or contact wire)and transmit a fault diagnosis result to operation and maintenance staff. The lateral pressure tension sensor with relatively high power consumption is controlled through hardware to achieve periodiccollection of a tension value and reduction of the wireless transmission quantity of business data, thereby greatly reducing the system power consumption of the tension collection device. The device is simple in structure and relatively light in weight, can directly measure the tension value of the carrier cable (or contact wire); the problems that the installation mode is inconvenient, a block fault of a catenary tension compensation device cannot be diagnosed and the power supply reliability of a power supply is relatively poor in the prior art are solved; and the device has relatively highengineering application value.
Description
technical field [0001] The invention relates to the related technical field of tension monitoring, in particular to an on-line monitoring and early warning system and method for the contact wire tension of a railway catenary load-bearing cable, which is mainly applied to the real-time monitoring, diagnosis and fault warning of the contact wire tension of a railway catenary load-bearing cable . Background technique [0002] In order to ensure the safe operation of the electrified railway, the contact line and the locomotive pantograph should maintain a stable and uninterrupted contact and current flow, so it is necessary to keep the wire tension of the catenary in a stable state at all times. Because the catenary works in a harsh field environment, not only the change of the outside temperature will affect the working state of the contact line, but also the huge impact force on the catenary when the train passes by will directly change the load-bearing cable and the tension o...
