Non-contact railway relay supporting piece gap measuring system and method

Abstract

The invention discloses a non-contact railway relay supporting piece gap measuring system and method. The system comprises a computer, a CCD image acquisition sensor, an adjustng assembly, a railway relay contact alignment device base, parallel light illumination equipment, and a CCD camera lens. A tested product is inserted into the railway relay contact alignment device base. The CCD image acquisition sensor is installed on one side of a tested object through the adjusting assembly to carry out image acquisition. The parallel light illumination equipment is arranged on the two sides of the CCD image acquisition sensor. A lens of the CCD camera is connected to the CCD image acquisition sensor. Rulers are adhered to a supporting sheet and a reed on the side surface of a railway relay. According to the system and the method, the coordinates of angular points at the top end of the supporting piece can be obtained more accurately, and a reed reflection area can be more obvious and real; point-to-point distance is represented by point-to-straight line distance, so that a measurement result is attached to a real supporting piece gap value, and the negative influence of the parameter measurement process on relay parameters is avoided.

Description

technical field [0001] The invention relates to a relay detection technology, in particular to a non-contact railway relay support plate gap measurement system and method. Background technique [0002] In the railway system, the railway relay is one of the very important components, it has many functions such as conversion circuit, automatic control and remote control. The control form often used in railway relays is electromagnetic type. The structure includes electromagnetic parts and contact parts. Its working principle is to control the action of the armature and the movable part by controlling the on-off of the electromagnetic coil, thereby changing the working state of the contact system. The electromagnetic gravity type or electromagnetic elastic gravity type used in the circuit of the fault-oriented safety performance. [0003] The factory inspection of the electromagnetic railway relay is mainly to measure and inspect its various performance parameters. Relay supp...

Problems solved by technology

This measurement method not only consumes a lot of manpower and material resources, but also has low efficiency, and the measurement results are greatly affected by the experience, technique and angle of the measurement personnel. In the actual measurement process, the relay shell needs to be opened, and the measuring tool and the relay contact mechanical Structural parts are in direct contact, so that the parameter measurement process itself may have a direct negative influence on the relay parameters
