Electric locomotive signal indicator

Abstract

The invention provides an electric locomotive signal indicator. The electric locomotive signal indicator comprises a controller, three infrared probes A, B and C connected with the input end of the controller and red, yellow and green tri-color signal lamps connected with the output end of the controller; each infrared probe comprises an infrared transmitting tube and an infrared receiving modulewhich are located inside; the controller comprises a single chip computer, three infrared probe detection circuits A, B and C, three signal lamp drive circuits and a stabilized voltage source supply circuit; the three reflective infrared probes are mounted on the outer side of a millhole railway, the probe B is located in the relative position in the middle of an aligning carriage, and the probesA and C are located in the relative positions of two ends of the aligning carriage; and each infrared probe detection circuit comprises an infrared transmitting drive circuit and an infrared receivingprocessing circuit. The electric locomotive signal indicator is simple in structure, convenient to mount, safe, reliable, economical and practical, and aligning speed of an ore loading carriage of anelectric locomotive can be greatly increased. The electric locomotive signal indicator can be applied to ore loading carriage alignment of the electric locomotive, ore unloading carriage alignment ofthe electric locomotive and other occasions needing aligning operation.

Description

technical field [0001] The invention relates to an indicating device which uses an infrared probe to detect the position of an ore loading car and uses a three-color signal lamp to indicate the alignment state of the car. Background technique [0002] In mines where trucks and electric locomotives are jointly transported, the loading speed of electric locomotives at the transfer station directly affects the transportation efficiency of electric locomotives. The loading speed of the electric locomotive mainly depends on the alignment speed at which the car enters the ore-drawing port and the ore-drawing speed at which the ore is loaded into the car. At present, the use of large vibrating ore-drawing equipment has solved the problem of slow ore-drawing speed. However, the problem of slow carriage alignment has not been well resolved. [0003] Electric locomotives are different from trucks. There are multiple compartments attached to the front of the locomotive. The driver is...

AI Technical Summary

Problems solved by technology

In this way, the commander stands at the ore opening, and may be injured by the ore flying out when the ore is drawn, and there is a certain potential safety hazard

In addition, when it is rainy or in the evening when the light is dark and the front of the truck is far away from the mine opening, the driver cannot see the semaphore clearly and it is difficult to perform alignment operations

Some people use the method of placing reference objects along the railway line for the driver to perform alignment operations, but due to problems such as the connection gap between the carriages, the alignment accuracy requirements cannot be met
