JPH0698329A - Dead angle supervisory equipment for vehicle - Google Patents

Abstract

PURPOSE:To supervise a dead angle area in real time by catching a video image of a dead angle area to the passenger and placing a monitor near the passenger. CONSTITUTION:A movable or stationary small sized television camera unit is mounted at a position at which a video image of a dead angle to a vehicle passenger or the like is caused. The video image caught by the telecamera unit is sent and displayed on a monitor near the passenger in a radio wave or through a calbe. The monitor is mounted on a place whose display is easily observed such as just above the instrument panel. The direction of even one camera is changed by a remote control or a kind of a lens is selected. With two cameras provided, the screen of the monitor is used through division. Thus, the passenger supervises almost completely a dangerous dead angle area in real time. Thus, the possibility of an accident is reduced, unease of employees is eliminated, their attention is effectively distributed and fatigue and stress on the job are reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for monitoring a blind spot such as the rear of a vehicle in real time. In the case of an aircraft, the operator can, for example, monitor the condition of the wheels.

[0002]

2. Description of the Related Art Blind spot monitoring devices such as concave mirrors and convex mirrors are typified by rearview mirrors.

[0003]

The conventional concave-convex / convex-mirror method is, for example, directly behind a vehicle having a box-shaped loading chamber, and a large trailer at the side opposite to the bending side and directly behind the vehicle body. Can't be monitored. Even if you're on a large bus, you can monitor and check right after
This is especially difficult when there are many passengers. Even if you try to eliminate blind spots by combining multiple mirrors, the image will be difficult to distinguish and many dangerous projections will be created on the car body. Therefore, the present invention intends to solve the problem that a driver or the like can easily monitor a blind spot of a vehicle, which cannot be removed by a conventional technique using a mirror, in a normal crew position.

[0004]

[Means for solving the problems] (a) Mount a small movable or fixed type TV camera unit at a position where the blind spot of a vehicle crew member can be captured as an image. (B) The image captured by the TV camera unit in (a) will be transmitted and projected on the monitor near the crew using radio waves or cables.

[0095]

[Operation] A crew member, such as a car, looks at a monitor installed in a place that is easy to see from the crew position. The crew then perceives the area on the monitor that would normally be a blind spot.

[0096]

[Embodiment] An embodiment of the present invention (for a large bus) will be described below. (B) TV camera part: The blind spot that cannot be covered by the concave mirror and the convex mirror of the large bus is right behind. There 2
A unit with a built-in color TV camera is mounted in the center above the rear of the bus. One of the two TV cameras is equipped with a wide-angle lens, which allows you to see everything right behind the vehicle. For the other, the type and angle of the lens are determined so that the direction directly behind can be projected far away. The unit covers the visual interface with tempered glass to prevent dust and moisture. In this example, two fixed color TV cameras were used because of the problem of failure, but even with one TV camera, the direction of the TV camera can be moved by remote control and the type of lens can be changed. You can get almost the same effect if you switch. Also, monochrome TV cameras and infrared TV cameras are not unavailable. In the case of large trailers, a TV camera unit can be mounted on the side of the vehicle to monitor the side of the vehicle opposite the turning direction. In that case, do you have two monitors in parallel?
It is also possible to divide the screen of one monitor and use it. (B) Monitor part: A single LCD color monitor is installed in a place where it is easy to see in a normal driver's cab, for example, just above the instruments. CRT type,
A monochrome monitor is also possible. Since there are two cameras in this embodiment, one monitor is used by switching the switch. A TV camera with a wide-angle lens, such as a platform where the bus is backed, is monitored for children and other obstacles directly behind the car body. Another normal TV camera with a lens is used to monitor the presence of mirrors on either side of the vehicle that are not in sight while driving, or the presence of a passenger car that is mounted a short distance directly behind. (C) What connects the TV camera and the monitor: In this embodiment, it is assumed that a normal cable is used. However, it can be replaced by wireless or optical fiber.

[0007]

[Effects of the Invention] The dangerous blind spot of the vehicle crew can be monitored almost in real time, thus reducing the risk of accident. By eliminating the anxiety caused by the invisibleness of drivers and other crew members, and effectively distributing attention, work fatigue and stress are reduced.

Claims (1)
