Application of OCS intelligent comprehensive inspection device in Hanzhong Yangan line

November 16 to November 18, our company's "OCS intelligent comprehensive inspection device" (hereinafter referred to as "equipment") carried out the acceptance test of Yang'an line in Mian County, Hanzhong County, in cooperation with the work area. During the test, dozens of kilometers were tested, during which the measurement of curves, anchor sections, switches tunnels were carried out. The feedback of field application shows that the measurement data of the equipment is accurate, the operation is reliable the operation is convenient.

Figure 1 field measurement

The equipment includes dynamic measurement accurate measurement module. The dynamic measurement realizes the automatic measurement of the geometric parameters of the pull-out value the guide height of the catenary realizes the function of 1C; the accurate measurement is used for the accurate measurement of the field data the dynamic measurement parameter calibration.

In the process of measurement, data accuracy is verified many times. The results show that the accuracy is <10mm. The measurement data is displayed in two forms of table curve, the data waveform is shown in Figure 2 below.

The equipment can measure various geometric parameters of catenary, including track gauge, superelevation, structural height, non support pull-out value guide height bearing cable pull-out value guide height.

Figure 4 overrun alert settings

In the measurement process, there are two ways of real-time warning for out of limit parameters, as shown in Figure 4. Range alert refers to the range alert of measurement parameters. In the figure, the pull-out value alert range is set as plus minus 450, the lead height range is 5300 ~ 7500. If any parameter exceeds this range in the measurement process, an over limit voice alarm will be given. Standard value alert, which is based on the standard value of parameters, needs to import basic data in advance. Assuming that the standard value of pull-out value lead height is (2405300), according to the setting in the figure, if the measured lead height pull-out value exceeds 5300 ± 10 240 ± 50 respectively, an over limit alarm will be given.

Figure 5 shows the over limit pull-out value found on site the review dialogue record with the operator.
