One-chip microcomputer based simulation test box for railway four-display of automatic occlusion and the method thereof

Abstract

The invention provides a one-chip microcomputer based simulation test box for railway four-display of automatic occlusion and the method thereof. The test box comprises a box body, a panel, a power supply module in the box body, a single-chip machine control module, an occlusion partition state detection circuit, an occlusion partition light strip control circuit, and a signaling machine lighting circuit. The panel is provided respectively with an occlusion partition state switch, an occlusion partition light strip and signaling machine signal lights. The method is performed through the following steps: inputting an occupied state or an idle state for the electric circuit of a simulated track through the dial of the occlusion partition state switch; receiving through the one-chip microcomputer the state information inputted by the occlusion partition state switch; controlling respectively the occlusion partition light strip control circuit and the signaling machine lighting circuit to output corresponding control signals so as to control the occlusion partition light strip and the signaling machine signal lights to display accordingly. With what is provided in the invention, it is possible to demonstrate the working principles of automatic occlusion in concentration and to improve teaching efficiency; small in size and stable and reliable in performance, the test box and the method are rather practical for future wider applications.

Description

technical field [0001] The invention relates to a simulation experiment equipment and a method thereof, in particular to a single-chip computer-based four-display automatic block simulation experiment box for a railway and a method thereof. Background technique [0002] The working principle of the existing four-display automatic block of the railway signal is: divide the interval between stations into several block partitions, set up a passing signal at the entrance of the blocking partition, and the four-display passing signal has three light positions from top to bottom : Green light, red light, yellow light. There are four kinds of displays: red light, yellow light, green-yellow light, and green light. It can predict the status of more than three block zones in front of the train, so that the train can run under the green light at a prescribed speed and cross the green light. After the yellow light, the high-speed train must slow down, and when it reaches the passing sig...

Problems solved by technology

[0003] Since the automatic blocking of the four-display of the railway needs to divide the inter-station interval into several blocking partitions, in the actual teaching process, at least four blocking partitions are required to fully demonstrate the automatic blocking of the four-display. Inter-interval lines, the number of signal machines set up is limited, and the signal machines in the blocking area are far away, so it is impossible to demonstrate the working principle of automatic blocking in a concentrated manner, and the expected teaching effect cannot be achieved.
