Abstract
The utility model discloses a collision avoidance system used for a direct current-alternating current locomotive, which comprises a first non-imaging laser radar, a second non-imaging laser radar, a programmable logic controller (PLC), a voice alarm, a frequency changer and a liquid crystal display (LCD) with a touching function used for setting parameters and displaying data. The first non-imaging laser radar is arranged on a locomotive head, and the second non-imaging laser radar is arranged on a locomotive tail. The collision avoidance system improves intellectualization level of the direct current-alternating current locomotive, greatly reduces probability of dangerous accidents caused by fatigue, carelessness, misjudgement and the like of a driver, and guarantees the direct current-alternating current locomotive to travel safely and efficiently.
Description
Technical field
The utility model relates to a kind of collision avoidance system that is used for straight-alternating current electric locomotive.
Background technology
Because the working environment of straight-alternating current electric locomotive is more abominable; Chaufeur very easily causes the collision of locomotive and obstacle to cause the generation of Peril Incident because of tired, carelessness, erroneous judgement are disconnected etc.; Even the phenomenon of locomotive derailing appears; For ensureing the safe in operation of straight-alternating current electric locomotive, the anti-collision technique that develops straight-alternating current electric locomotive is very crucial.
The utility model content
The purpose of the utility model is to provide a kind of can reduce straight-alternating current electric locomotive Peril Incident occurrence probability greatly to ensure the collision avoidance system that is used for straight-alternating current electric locomotive of straight-alternating current electric locomotive safe operation.
This collision avoidance system that is used for straight-alternating current electric locomotive that the utility model provides; Comprise the first non-imaging type laser radar, the second non-imaging type laser radar, PLC, phonetic alarm, frequency converter and be used for setup parameter and the LCD display of the band of display data touch; The said first non-imaging type laser radar is installed on locomotive head; The said second non-imaging type laser radar is installed on the locomotive tailstock, and locomotive is to overtake the time, the work of the first non-imaging type laser radar; Measure the distance and the orientation of the place ahead obstacle; When locomotive went backward, the second non-imaging type laser radar was worked, and measured the distance and the orientation of rear obstacle; PLC reads distance and the bearing data of the first non-imaging type laser radar or the second non-imaging type obstacle that laser radar is surveyed according to the travel direction of locomotive and these data is handled; PLC is according to data processed result and setup parameter output controlling quantity is controlled phonetic alarm enforcement audio alert and control frequency converter driving machine vehicle motor is made corresponding run action, and simultaneously, the LCD display that PLC gives said band touch the data of needs demonstration output shows.
Data communication in this collision avoidance system between each parts adopts the CAN bus to communicate.The parameter of on the LCD display that said band touches, setting comprises deceleration distance and the stopping distance between locomotive and the obstacle between alarm distance, locomotive and the obstacle between locomotive and the obstacle.The LCD display content displayed that touches at said band comprises the distance between locomotive and the obstacle, speed, alarm, deceleration prompting and the prompting of stopping of locomotive.
The utility model has improved the intelligent level of straight-alternating current electric locomotive, has reduced greatly to cause the Peril Incident odds because of driver fatigue, carelessness and erroneous judgement are disconnected etc., has ensured safe, the efficient operation of straight-alternating current electric locomotive.

The specific embodiment
Fig. 1 is the functional block diagram of the utility model; Comprise the first non-imaging type laser radar, the second non-imaging type laser radar, PLC, phonetic alarm, frequency converter and be used for setup parameter and the LCD display of the band of display data touch, the data communication between above-mentioned each parts adopts the CAN bus to communicate.The parameter of on the LCD display that band touches, setting comprises deceleration distance and the stopping distance between locomotive and the obstacle between alarm distance, locomotive and the obstacle between locomotive and the obstacle.The first non-imaging type laser radar is installed on locomotive head, and it is used to detect the distance and the orientation of the place ahead obstacle, and the second non-imaging type laser radar is installed on the locomotive tailstock, and it is used to detect the distance and the orientation of rear obstacle.When locomotive to overtake the time; The work of the first non-imaging type laser radar; PLC reads distance and the bearing data of the first non-imaging type obstacle that laser radar is surveyed and these data is handled; PLC is according to data processed result and setup parameter output controlling quantity control phonetic alarm implements audio alert and control frequency converter driving machine vehicle motor is made corresponding run action, shows the distance between locomotive and the place ahead obstacle, speed, alarm, deceleration prompting and the prompting of stopping of locomotive at the LCD display that band touches simultaneously; When locomotive goes backward; The work of the second non-imaging type laser radar; PLC reads distance and the bearing data of the second non-imaging type obstacle that laser radar is surveyed and these data is handled; PLC is according to data processed result and setup parameter output controlling quantity control phonetic alarm implements audio alert and control frequency converter driving machine vehicle motor is made corresponding run action, shows the distance between locomotive and the rear obstacle, speed, alarm, deceleration prompting and the prompting of stopping of locomotive at the LCD display that band touches simultaneously.As the alarm distance of setting between locomotive and the obstacle is 50 meters, and then phonetic alarm can be implemented audio alert and has obstacle with 50 meters of prompting chaufeur when locomotive is 50 meters apart from the place ahead or rear obstacle; As the deceleration distance of setting between locomotive and the obstacle is 30 meters, then when locomotive is 30 meters apart from the place ahead or rear obstacle, on the LCD display that band touches, can will slow down by the prompting chaufeur; As the stopping distance of setting between locomotive and the obstacle is 10 meters; Then when locomotive is 10 meters apart from the place ahead or rear obstacle; On the LCD display that band touches, can please stop by the prompting chaufeur, not have enough time to stop like chaufeur, then system can automatically perform parking procedure.
