JPH01287800A - On-vehicle alarm - Google Patents

Abstract

PURPOSE:To prevent a serious accident when a driver overlooks a signal carelessly by receiving a radio wave which is sent outside a vehicle and generating an alarm tone. CONSTITUTION:A receiving circuit 1 receives the radio wave a1 which is sent from outside, e.g. the signal installed on a road and analyzes it to output control signals b1-bn corresponding to the radio wave a1. An alarm tone generating circuit 2 inputs the control signals b1-bn outputted by the receiving circuit and generates the alarm tone. An on-vehicle alarm like this is mounted on the vehicle and then even if the driver overlooks the signal carelessly, the driver's attention is attracted by the alarm tone to prevent a serious accident.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an alarm device installed in a vehicle, etc., which receives radio waves emitted from outside the vehicle (for example, a traffic light placed on a road). In-vehicle device that emits an alarm sound! This is related to F alarms.

[Conventional technology] Traditionally, this type of car @,! There was no J alarm.

For this reason, conventionally, a driver visually confirms the display of a traffic light (for example, a blue, yellow, or red display) and drives an automobile or the like according to the instructions of the traffic light.

[Problems to be solved] As mentioned above, in the past, there was no warning device of this kind and the driver had to visually check the display of the traffic light, so there was a possibility that the driver would inadvertently overlook the display of the traffic light, etc. There was a problem in that such a case could lead to a serious accident.

The present invention was made in view of the above problems, and by receiving radio waves emitted from outside the vehicle and emitting a warning sound, even if the driver misses the traffic light due to inattention,
The aim is to provide an on-vehicle alarm that can prevent serious accidents.

Solution to Problem c] In order to achieve the above object, the car A2 alarm device of the present invention is an alarm device installed in a car, etc., which receives radio waves emitted from outside the vehicle and responds to the radio waves. The configuration includes a receiving circuit that outputs a control signal, and an alarm sound generating circuit that receives the control signal output from the receiving circuit and generates an alarm sound.

[Embodiment] Next, an embodiment of the in-vehicle alarm according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, 1 is a receiving circuit that receives radio waves a1 emitted from a traffic light installed outside the vehicle, for example, on the road, analyzes this, and sends control signals b1 to b1 corresponding to the radio waves al.
Output bn.

Reference numeral 2 denotes an alarm sound generating circuit, which receives control signals b1 to bn output from the receiving circuit 1 and generates an alarm sound.

The radio wave a1 emitted from the traffic signal may be emitted, for example, only when the traffic light is displayed as "red", or even when the signal is displayed as "blue", "yellow", or "red". It may also be configured to be fired.

If the signal is set to be emitted regardless of whether "Blue", "I/+2", or "Red" is displayed, when the radio wave AL is received, the receiving circuit 1 will identify this and, for example, "Red" will be emitted. ”, or to output a control signal in both cases and differentiate this control signal so that it is “blue”, “yellow”, “ It is also possible to emit an alarm sound with a different tone depending on the color "red".

The above-mentioned in-vehicle alarms are installed and used in cars, etc., and even if the driver is careless and misses a traffic light, the alarm sounds to alert the driver and prevent a serious accident. It can be prevented.

[Effects of the Invention] As explained above, by installing the car S1G alarm device of the present invention in a car, even if the driver misses a traffic light due to inattention, the car S1G alarm device of the present invention can call the driver's attention with an alarm sound. This has the effect of making it possible to prevent serious accidents.
