Abstract

PURPOSE:To improve safety enabling a condition of abnormality to be automatically supervised and recorded in a picture by constituting a system so as to automatically start a rear watching television device, comprising a television camera and a monitor television, by a space sensor provided behind a vehicle. CONSTITUTION:A vehicle behind watching television device contributes to safety operation of a vehicle in the time of its reversing or the like by mounting a television camera 2 behind the vehicle 1 while setting up a monitor television 3 in a position visible from a driver's seat and copying a picture image, taken by this television camera 2, in the monitor television 3 thus watching this picture image. Here, the vehicle 1 mounts to its behind an ultrasonic type space sensor 6 which detects an ultrasonic wave to be reflected, for instance, from an object. In case of the object being placed in a detecting range of this space sensor 6, its detection signal actuates a relay 71 in a space sensor control part 7 closing a contact K1 of the relay 71, and the television device 3 is instantaneously actuated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle rear monitoring television device that monitors the rear of a vehicle using a television camera.

[Prior Art J] Figure 3 is a system diagram showing a conventional vehicle rear monitoring television. In the figure, (1) is the vehicle, (2) is the television camera,
(3) is a monitor TV, (4) is a pack gas Isech, (5) is a JEltli battery, (8) is a TV camera, (2) is a TV monitor, and (3) is a transmission cable that transmits signals between the two. 31) Preheat circuit in the monitor TV (3), (51) is the power cord that supplies the preheat circuit (31) K power from the battery (5), (52)
is a power cord that supplies main power from the battery (5) to the monitor (3) via the reverse gear switch (4).

Next, the operation will be explained. As shown in Figure 3, the vehicle (
A TV camera (2) is installed behind the vehicle (1), and a monitor TV (3) is installed in a position visible from the driver's seat in the vehicle to monitor the rear of the vehicle, which is a blind spot from the driver's seat, and to ensure safe driving when reversing. It is something to do.

The power supply for the television device is from the battery (5) to the monitor television (
3), and the TV camera (2) is supplied with a transmission cape/
'(8). Normally, power is supplied from the battery (5) to the preheat circuit (31) in the monitor television (3) through the power cord (51) to keep the television set in a standby state, and when backing up, the back gas switch is activated. (4)
When turned on, main power is supplied through the power cord (52), the television device is activated instantly, and the vehicle is driven in reverse while monitoring the rear of the vehicle.

[Problems to be Solved by the Invention J] Conventional vehicle rear monitoring television systems operate as described above, so they can only monitor when the vehicle is reversing, and cannot detect abnormalities at the rear of the vehicle when it is stopped or moving forward. There were problems such as the impossibility of dealing with this issue.

This invention was made to solve the problems mentioned above, and it is a vehicle that can automatically detect and monitor abnormal conditions behind the vehicle even when the vehicle is stopped or moving forward, and can also record it if necessary. The purpose is to obtain a rear surveillance system.

Means for Solving Problem c] The vehicle rear monitoring system according to the present invention is a system in which a space sensor is added to a conventional vehicle rear monitoring television device.

[Function] The space sensor in this engine is installed at the rear of the vehicle,
Automatically activates the vehicle rear monitoring television system even if an abnormal object is detected.

[Embodiment J of the Invention An embodiment of the invention will be described below with reference to the drawings. 1st
In the figure, (6) is an ultrasonic type 0 space sensor that detects the reflection of ultrasonic waves from objects, for example, and is installed at the rear of the vehicle. (7) is a control part of the space sensor (6), and when the sensor is activated, an internal relay K (71) is activated and closes the contact point 1.

Next, the operation will be explained. When the space sensor (6) and space sensor system #15 (7) are excluded, the operation is the same as the conventional O vehicle rear monitoring television system, and the back gas switch? When (4) is turned on, the television device instantly operates and monitoring becomes possible.

In the present invention, a space sensor (6) is attached to the rear of the vehicle as shown in the figure, and the detection range is set to almost cover the viewing angle of the television camera (2).

When an object enters the pIt detection range of the space sensor (6), the space sensor (6) detects it and sends a K signal to the space sensor control unit (7).
The internal relay K (71) operates and closes its contact Klt. Since both ends of the contact 1 are connected to the battery (5) and the power cord (52), when the contact 1 closes, the television set is activated instantly.

As described above, the space sensor (6) detects an object within its detection range and instantly activates the television device.

Another embodiment is shown in FIG. 2, and reference numeral (9) is an in-vehicle VTR which is supplied with power from a battery (5) through a power cord (51). Relay connection a in space sensor control unit (7)
It has a Nik of H x 1 and IK of 2. Space sensor (
When an object enters the detection range of 6), the relay K (71) in the space sensor control section (7) is activated and its contact Kl is activated.

K2 closes. When the contact Kl closes, the television set is instantaneously activated as in the example of FIG. When contact 2 closes, the close signal activates the VTR and starts recording.

As described above, the space sensor (6) detects an object within its detection range, and the vTR is instantly activated together with the television device to start recording. Furthermore, it can be easily inferred that by increasing the number of contact points of the relay K (71) in the space sensor control section (7), functions such as rare frame transmission can be added.

[Effects of First Effect] As described above, according to the present invention, the space sensor installed at the rear of the vehicle detects an abnormal object and automatically activates the vehicle rear monitoring television device or VTR, so that the vehicle can be stopped easily. Abnormal conditions can be automatically monitored and recorded even when the vehicle is moving forward or unattended, and the abnormal condition can be analyzed later by V'l'R.
