Abstract

Claims (22)

1 . A device for monitoring railway health in a windy desert area, comprising: a spring vibration assembly, a bracket, a housing, a light-emitting diode (LED) emitter, a receiving processing assembly, and fixing screws;

wherein the spring vibration assembly and the bracket are fixedly connected through a base threaded stud and a positioning nut, the bracket and the housing are fixedly connected through the fixing screws, the LED emitter and the receiving processing assembly are fixedly connected to the housing by adhesive bonding, and the receiving processing assembly, the LED emitter and a mass ball in an equilibrium position are installed on a same straight line to ensure that a light emitted by the LED emitter is received by the receiving processing assembly when the light is unobstructed by the mass ball.

2 . The device as claimed in claim 1 , wherein the spring vibration assembly comprises the mass ball, a spring, the base threaded stud and the positioning nut, the mass ball is fixedly connected to a top of the spring, a bottom of the spring is fixedly connected to the base threaded stud, and a lower part of the base threaded stud is connected to the positioning nut in threaded connection.

3 . The device as claimed in claim 1 , wherein the bracket comprises a base and an upper bracket, and a bottom of the upper bracket is fixedly connected to the base.

4 . The device as claimed in claim 1 , wherein the receiving processing assembly adopts a photosensitive triode, and the photosensitive triode is configured to convert a received optical signal into indication information or an electrical signal capable of being processed by a computer.

5 . A monitoring method using the device for monitoring railway health in the windy desert area as claimed in claim 1 , comprising:

step (1), fixing the whole device on a bed timber of a monitoring point of a railway line with wind and sand by connecting bolt groups to form a monitoring system;

step (2), driving the mass ball in the spring vibration assembly by a train to vibrate when the train passes by, making the mass ball deviate from an equilibrium position and the light emitted by the LED emitter be received by the receiving processing assembly, after illuminating a photosensitive triode in the receiving processing assembly, conducting a circuit of the receiving processing assembly, making an indicator light flash, obtaining a conducted electrical signal by a computer through an external circuit, and recording a power-on duration; and

step (3), judging sand accumulation in a railway track according to the power-on duration or a flashing duration of the indicator light, so as to achieve real-time monitoring of the sand accumulation in the railway track.

6 . The monitoring method as claimed in claim 5 , wherein in the step (3), the power-on duration or the flashing duration of the indicator light is:

T

=

K

m

+

m

t

;

where, T is the flashing duration of the indicator light of the device after the train passes;

K is a response constant of the device;

m is a system mass; and

m t is a system added mass after sand accumulation.
