Automatic operation device of railway model, two-train automatic operation method, and two-train rear-end collision preventing automatic operation method of railway model

Abstract: PROBLEM TO BE SOLVED: To provide an operation method capable of automatically operating two trains at a constant speed and automatically preventing a rear-end collision when two trains are made to run in the same direction without special work on the power car of a train. SOLUTION: In the operation method, the power car of a railway model such as N gauge and lines in which entire line is divided into a plurality of sections 1, 2, 3, 4 and 5 and insulated respectively are used. The device includes a microcomputer section for processing of detecting on which section of the line the train is present regardless of the running or stop of the power car and detecting speed information, or the like, and a personal computer section 50 for transferring control information to the microcomputer section. An automatic operation is performed, automatic stop is performed, a rear-end collision is prevented when two trains are operated in the same direction, and various high-grade automatic operations are made possible.

Motor vehicle deceleration indicators.

Abstract: The author discusses rear end collisions and the efficiency of brake lights in providing a warning to following drivers. Alternative systems are discussed including engine deceleration displays and direct display of deceleration. A system is then proposed which addresses the need to reduce both thinking time and braking time by means of expanding arrays of stop lamps. A row of stop lights on the rear of a vehicle is matched by an interior display inside the following vehicle and comparisons of deceleration can be made by the driver.

Device for preventing rear-end collision of vehicles

Abstract: The utility model relates to a device for preventing the rear-end collision of vehicles. The device comprises ranging radars (3), a displaying alarm (2) and electromagnets (1). The ranging radars (3) are arranged on the front end and the rear ends of two sides of a vehicle; the displaying alarm (2) is arranged in a carriage of the vehicle; and the electromagnets (1) are arranged in the front end and the rear end of the vehicle. The device provided by the utility model adopts a micro-processing controller, can be used for guaranteeing the traffic safety in daily life and reduces the loss of life and property.

Study on Rear-end Collision Avoidance Technology

Abstract: On the basis of the theory module,the main influence factors of realizing rear-end collision avoidance are discussed,such as the measure technologies of the following distance,the driving circumstance,the driver factors,and the warning methods and warning frequency of rear-end collision avoidance.The study methods of rear-end collision avoidance technology are pointed out briefly.

Rear-end collision preventive safety device

Abstract: A rear-end collision preventive safety device is mainly characterized in that the front end of a hydraulic damping device is connected with an automobile bumper via a high-rigidity spring, indicator lamps of an alarming device are mounted in a vehicle and a rear window of the vehicle, a safety belt locking device is fixed on a seat of the vehicle via bolts, and an X-ray transceiver is connected with a vehicle body via bolts. The rear-end collision preventive safety device can effectively make up safety protection bug when in brake failure.
