Embodiment

[0031] The hardware detection device adopted in this embodiment is as figure 2 , 3 As shown, it includes two grating type displacement sensors 2 installed and fixed on the same side of the same track plate 5 and two circuit boards (inside the box, not shown in the figure) arranged in the junction box 4 . Its grating type displacement sensor 2 is connected with the circuit board in the junction box 4 in one-to-one correspondence, and is respectively arranged at the two ends of the track plate 5 sides, and the circuit board and the junction box 4 are installed on the track cement ground surface layer 7 . There are interfaces in three directions on the junction box 4, two of which are respectively connected to the front and rear adjacent junction boxes 4, and the other interface is connected to the grating displacement sensor 2. For details, see figure 1 .

Abstract

The invention relates to a method for automatically monitoring cracks of a track plate by using a grating displacement distance measurement principle, which carries out automatic monitoring by adopting a monitoring device with grating displacement sensors. The method comprises the steps of 1) fixing the grating displacement sensors on the side surface of the track plate; 2) respectively installingand connecting circuit boards for the grating displacement sensors, and then connecting each circuit board to a collection box to form a monitoring data transmission path; 3) starting a power supplyand network connection, wherein the grating displacement sensors start to monitor cracks; and finally, transmitting monitoring signals of each monitoring point to a cloud platform server for storage and comparison, and giving a warning reminder at the right moment. According to the method, the automatic monitoring purpose of point-by-point monitoring and centralized collection is realized, and theprecision can reach up to 0.01mm. Meanwhile, the method realizes automatic measurement for cracks at each monitoring point of the line, and the data can be uploaded to a cloud platform, thereby improving the monitoring efficiency of cracks of the track plate, and having great economic and social benefits.

Description

technical field [0001] The invention relates to the field of automatic monitoring, in particular to a method suitable for automatic monitoring of track plate cracks in high-speed track engineering by using the principle of grating displacement distance measurement. Background technique [0002] This patent belongs to the field of automatic monitoring. The comfort and safety of operating high-speed rail requires a set of high-standard requirements. Among them, the crack between the track slab and the cement base is a very critical parameter, because the track slab is laid on the cement base in the later stage. The junction between the two will be affected by temperature changes and other factors, and cracks will occur. The main performance is that the track plate is arched relative to the base. When the crack value reaches 3mm, an early warning is required, and when the crack value reaches 6mm, an alarm is required. At present, the monitoring method is mainly manual monitorin...
