High-and low-tone whistle control device for locomotive whistle and control method of high-and low-tone whistle control device

Abstract

The invention discloses a high-and low-tone whistle control device for a locomotive whistle. The device comprises a whistle switch, a locomotive master control microcomputer and a locomotive high-and low-tone whistle controller. The locomotive high-and low-tone whistle controller receives switch quantity signals of the whistle switch and a locomotive whistle scheme of the locomotive master control microcomputer and outputs instructions to a high-tone/low-tone electric pneumatic valve at an end I or an end II of a locomotive. The high-and low-tone whistle control device has advantages that 1) intelligent level of the locomotive is raised, and operation error rate is decreased; 2) automatic whistling in specific zones is realized, so that operations are simplified for a driver, and the driver can complete tasks only through a simple operation; 3) a control circuit is simplified greatly, and devices and wires are reduced; 4) logic control circuit nodes are reduced, failure rate is decreased, and reliability of the locomotive is improved.

Description

technical field [0001] The invention relates to the technical field of locomotive bagpipes, in particular to a high and low pitch whistle control device for locomotive bagpipes and a control method thereof. Background technique [0002] Today, as environmental protection requirements are getting higher and higher, noise pollution has also attracted more and more attention. At a certain time or place, the use of appropriate whistle methods will also be included in the scope of driver operating requirements. When existing locomotives use high and low pitched bagpipes, according to different operating conditions, it is necessary to perform logical control of high and low pitched whistles, low pitched whistles, and simultaneous high and low pitched whistles, and automatically change the direction of the whistle according to the direction of travel . The operation mode of the existing locomotive is completely dependent on human operation, and the degree of intelligence is low. I...

Problems solved by technology

Although the realization of the manual operation function is not difficult to achieve, the circuit construction is relatively cumbersome. The whistle switch needs to be multi-point configured according to the logic and customized separately; the logic control circuit is built with functional devices, and the device and circuit construction is cumbersome. , especially for double-cab locomotives, since two sets of switches with the same function are controlled at the same time, mutual electrical isolation needs to be considered, and the auxiliary contacts of multiple direction switches need to be connected in series to the control circuit to control the direction of the whistle. Functional devices And the construction of the line is particularly complicated

Due to the large number of control circuit nodes, the failure rate is high
