Embodiment Construction

[0036] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0037] like figure 1 As shown, an online monitoring system for the looseness of subway catenary support is disclosed in the embodiment, which mainly includes a plurality of intelligent monitoring devices installed on the subway catenary support, transmission cables, and a host computer. The intelligent monitoring device is installed on the subway catenary support. , connected to the transmission cable bus in parallel through the transmission cable, and communicate with the host computer through the transmission cable bus.

[0038] combine figure 2 As shown, the intelligent monitoring device includes a data acquisition unit, a data processing unit, a storage unit and a signal input and output unit, which is equivalent to a new type of intelligent sensor.

[0039] The data acquisition unit mainly collects the acceleration values ​​in the X, Y, and...

Abstract

The invention discloses a contact net support looseness intelligent monitoring device. The device comprises a data acquisition unit, a data processing unit, a storage unit and a signal input and output unit. The data acquisition unit collects an acceleration value of a contact net support to be tested in a triaxial direction; the storage unit records an initial triaxial angle, a vibration quantityfeature value, a preset angle difference threshold value and a preset vibration quantity feature value difference threshold value; the data processing unit analyzes and processes the collected triaxial acceleration value and compares the difference between the obtained real-time triaxial angle and an initial value and the difference between the obtained real-time vibration quantity feature valueand the initial value with the angle difference threshold value and the vibration quantity feature value difference threshold value respectively to obtain an output signal reflecting the looseness situation of the monitored contact net support. On this basis, the invention also discloses a contact net support looseness online monitoring system and a method thereof. Through the device, the system and the method thereof, an accurate judgment of the looseness situation of the contact net support can be achieved, and the construction difficulty and the construction cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of subway tunnel engineering, and in particular relates to an intelligent monitoring device, an online monitoring system and a method thereof for on-line monitoring of the looseness of subway rigid catenary supports. Background technique [0002] Under the double action of the vibration caused by the long-term reciprocating operation of the train and the piston wind of the train, the installation and fastening of the bracket carrying the high-voltage catenary has a great risk of loosening and failure. At this stage, the conventional catenary supports are densely arranged and the distance is long. There is no effective online monitoring method for the looseness of the mounting brackets. Generally, manual regular inspections are used to judge whether there is displacement based on the relative positions of the marks. The inspection efficiency is low and it is easy to miss. The invention patent application with...
