Remote monitoring system for hollow axle flaw detector

Abstract

The invention discloses a remote monitoring system for a hollow axle flow detector. Remote monitoring software is designed according to certain data format specifications, establishes contact between a flaw detector control system and a host and realizes the remote monitoring of the enterprise host over the flaw detector control system. Moreover, a first remote monitoring protocol module is arranged on an intelligent terminal, and correspondingly, a second remote monitoring protocol module is arranged on the flaw detector control system. The first and second remote monitoring protocol modulesspecify a data format of a communication message between the host and the flaw detector control system, so data inconsistent with the specifications is prevented from entering the flaw detector control system, and particularly, the possible threads of virus data to the flaw detector control system are avoided. The communication message is transmitted after being converted into the data in the specified format, so the security of the communication message is ensured.

Description

technical field [0001] The invention relates to the field of non-destructive flaw detection, in particular to a remote monitoring system for a hollow axle flaw detector. Background technique [0002] The hollow axle flaw detector is used to automatically detect fatigue cracks on the inner and outer surfaces of hollow axles of rail transit vehicles such as high-speed EMUs and subways, and analyze their fission trends. It can also be used to detect internal defects of hollow axle materials, such as pores or inclusions in materials, etc. , in order to achieve early warning and ensure driving safety. The hollow axle flaw detector mainly includes the probe rod (including multiple ultrasonic probes), the feeding mechanism, the ultrasonic electronic processing unit, the control system and other parts. Supply couplant to the start-up hydraulic system of the mechanism. The ultrasonic probe installed on the probe rod emits ultrasonic waves in the center hole of the hollow axle, and a...
