A method and device for ensuring driving safety of electric engineering vehicles

Abstract

The invention discloses a method and a device for ensuring driving safety of an electric power engineering vehicle, and belongs to the field of electric power engineering operating vehicles. A side-looking camera is arranged on a sight glass shell at the right outer side of the vehicle; a video output signal of the side-looking camera is correspondingly connected with a video output signal of an original reversing camera in parallel and then connected with a video signal input end of a navigating instrument; a two-position double-toggle switch is arranged for switching the side-looking camera, a power supply of the original reversing camera and the navigating instrument to display a trigger signal; the two-position double-toggle switch is arranged at the first position when the vehicle is in a reversing state; the navigating instrument displays an image shot by the reversing camera; and the two-position double-toggle switch is arranged at the second position when the vehicle is not in the reversing state, and the navigating instrument displays the image shot by the side-looking camera. Therefore, the visualization of an external environment of the side azimuth at the right side of the vehicle at the position of a driver is achieved; a visual blind area of the driver in a driving process of the vehicle is removed, and the security of the electric power engineering vehicle in the driving process is ensured.

Description

technical field [0001] The invention belongs to the field of electric engineering operation vehicles, and in particular relates to a method and a device for eliminating blind spots in the driver's field of vision. Background technique [0002] In actual work, a lot of various electrical equipment are installed in places with complex working environment, no good road conditions or complex ground conditions. [0003] With the application and development of mechanized construction, more and more large-scale electric power engineering vehicles (including electric emergency vehicles) are used in daily power construction, patrol inspection or on-site equipment maintenance and repair work, which greatly improves the field outdoor construction and repair work. work efficiency. [0004] At the same time, with the complexity and diversification of the working environment, various driving / driving accidents of electric engineering vehicles have also increased. [0005] In order to ens...

Problems solved by technology

[0008] However, due to manufacturing cost considerations, these active and passive safety technologies are usually equipped on some medium and high-end cars or off-road vehicles, and rarely configured for on-site construction vehicles such as electric engineering vehicles.

[0009] Moreover, during the actual on-site driving operation, due to the existence of blind spots in the interior and exterior rearview mirrors, the driver is usually unable to observe the actual position of the front or side of the right front wheel of the vehicle (that is, the side of the right A-pillar). ground conditions, this brings great difficulty and inconvenience to the movement and driving of electric engineering vehicles in places with complex ground conditions, and also affects the safety, smooth and rapid progress of on-site construction operations

[0010] If the above-mentioned blind spot information system is installed on the existing electric power engineering vehicle, firstly, the modification cost is relatively high, and it can only warn the blind spots in the middle and rear directions on both sides of the vehicle, which cannot solve the problem of visual field observation in front of the right side of the vehicle; The second is that this kind of modification often involves the modification of the original control circuit of the car, and the modification of the vehicle is also restricted by various regulations of the vehicle management department of the public security organ. The vehicle management functional department sets a high threshold for the modified car , how to make the modification of the vehicle conform to the restrictions of various regulations of the vehicle management department is also a difficult point in the actual vehicle equipment management
