New Rail Thermometer

Abstract

The invention discloses a novel rail thermometer, which includes a hand-held device end and a temperature measurement end connected by a communication cable; the hand-held device end includes an OLDE display screen, a film button panel, a power supply battery, and a The battery is fixed inside the electronic compartment box to supply power for the OLDE display and the electronic circuit board of the single-chip microcomputer. The electronic circuit board of the single-chip microcomputer receives the input signal of the membrane button panel, controls the display of the electronic display, and communicates with the temperature measurement terminal through the communication cable; the temperature measurement terminal It includes a metal shell formed by the outer shell and the inner shell, a ring magnet nested between the inner shell and the outer shell, a circuit board fixed on the inner shell and welded on the circuit board, and facing the metal shell Infrared thermometer at the open end of the body, the open end of the metal shell is closed by a heat-conducting silver sheet. The novel rail thermometer of the invention has the advantages of light and firm structure, convenient operation, good protection, high precision and fast response speed of temperature measurement.

Description

technical field [0001] The invention relates to a novel rail thermometer and belongs to the technical field of electric circuits. Background technique [0002] The rail thermometer is a special test instrument for measuring the surface temperature of the rail on the railway. Whether it is the laying construction and maintenance of the line, or the rail replacement operation, as well as the "three defenses" (anti-expansion, anti-breakage, and heatstroke prevention) of the public works department, the main basis must be the temperature of the rail. With the rapid development of modern railways, the requirements for lines are getting higher and higher. Therefore, there are correspondingly higher standards for the accuracy and stability of rail thermometers. [0003] At present, there are two types of rail thermometers used on the line: bimetallic rail thermometers and analog signal digital rail thermometers. The analog signal digital rail thermometers have fast response speed...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of rail thermometer based on the shortcomings of the above-mentioned prior art, which can shorten the thermal equilibrium time between the surface of the measured rail and the temperature sensor, and solve the problem of time-consuming measurement under high-precision temperature measurement conditions
