Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice warning device for automatically issuing a voice message such as a warning to passersby at various construction sites.

[0002]

2. Description of the Related Art At various construction sites such as roads, electricity, gas, water and sewage systems, and telephones, the conventional method of communicating the dangers and cautions to passers-by is to inform or guide them by field workers or security guards. , There are various display lights and posters.

[0003]

[Problems to be Solved by the Invention] However, in the case of having a dedicated field worker or security guard, the labor cost is high, and
There is a problem that the physical and mental burden is great at night, in extreme heat and cold, and in bad weather, and it is dangerous depending on the situation of the site. Furthermore, the method of visually appealing using various kinds of indicator lights and posters is often overlooked, and it is still insufficient to thoroughly inform passers-by of the dangers and cautions at the time of passage. In addition, various existing indicator lights are generally complicated and large in size, and have many protrusions and the like, which is inconvenient for transportation and storage.

The present invention has been made to solve the above problems, and its purpose is to reliably convey the dangers and cautions at the time of passage to a passerby to ensure the safety and convenience of the passerby. Another object of the present invention is to provide a voice warning device which has a simple structure, is easy to transport and store, and can be provided at low cost.

[0005]

To achieve the above object, the present invention provides a human body detecting section for detecting a pedestrian approaching within a certain range, and a control signal generated by an output signal from the human body detecting section. A signal processing unit and a voice message output unit for outputting a voice message such as a warning or a caution from a speaker based on the control signal.

The present invention further comprises a message selection unit for selecting any one of a plurality of types of voice messages stored in advance, and the voice message selected by this message selection unit is output via the voice message output unit. It is desirable to output. Further, the specific voice message stored in the exchangeable storage medium may be output via the voice message output unit.

The human body detection unit, the signal processing unit, the voice message output unit and the speaker are built in a hollow conical triangular pole (so-called color cone).

[0008]

According to the present invention, when a pedestrian approaches within a certain range, the human body detection unit automatically detects it, turns on the warning light, and outputs a warning or attention to the pedestrian as a voice message. To do. Further, by incorporating all the components into the triangular pole, it is possible to realize a voice warning device which is convenient for transportation and storage without any protrusions and which does not feel uncomfortable in appearance.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of this embodiment. The audio warning device 30 of the present invention has a mounting tool 18 fixed to the inside of a hollow conical triangular pole (so-called color cone) 17 placed at, for example, a construction site, and the supporting tool 1 is attached to the mounting tool 18.
9 is integrally fixed, and various parts to be described later are attached to the support tool 19 to be configured.

FIG. 2 is a block diagram showing the main part of this embodiment. The configuration of the embodiment will be described below with reference to the block diagram and the configuration diagram of FIG. 1 and 2,
Reference numeral 11 denotes a human body detection unit that uses an infrared sensor, an ultrasonic sensor, or the like, and is for detecting that a passerby M is approaching within a certain range from this device.

A signal processing unit 12 is connected to the human body detecting unit 11 and operates to receive a human body detecting signal and send a control signal to a subsequent circuit. At the same time, the signal processing unit 12 also controls transmission / reception of the human body detection unit 11.

A voice message output unit 13 is connected to the output side of the signal processing unit 12. The voice message output unit 13 is for receiving a control signal from the signal processing unit 12 to drive the speaker 14 and issuing a voice message such as a warning or caution to the passerby M. Specifically, a tape recorder, an IC sound source, etc. can be considered.

Reference numeral 15 denotes a message selection unit, which allows a user to select a desired one from a plurality of voice messages stored in advance by operating a switch or the like. The message selection unit 15 stores a specific voice message in a replaceable storage medium such as a ROM card, and by mounting this storage medium, the voice message output unit 13
The voice message may be read from the side. An example of a voice message is "Because of the construction,
We apologize for the inconvenience. Please be careful and pass by. , Etc., etc., and the construction time, construction period, construction content, contact information, detours, etc. may be explained.

According to the present invention having the above-mentioned configuration, the human body detecting section 11, the signal processing section 12, the voice message output section 13 are provided.
Also, the message selection unit 15 is built in and integrated with the speaker 14 in the triangular pole 17 of FIG. As the power source 16 shown in FIG. 1, an AC power source, a battery, a dry cell, a button cell, or the like is used. Further, the type of the speaker 14 may be unidirectional or omnidirectional.

In the above embodiment, if the directivity of the human body detecting section 11 and the speaker 14 is changed by directing the triangular pole 17 in an arbitrary direction, restrictions on the installation place are reduced. Also,
A plurality of human body detection units 11 and a plurality of speakers 14 may be installed to output a voice message to a passerby M in multiple directions. Further, the present invention has a waterproof (insulated) and dustproof structure as a whole, and is lightweight and easy to move and install.

In use, for example, when the voice warning device 30 of the present invention is installed in the mode shown in FIG. 1, the human body detection unit 11 detects a passerby M approaching within a certain range,
A control signal is sent to the voice message output unit 13 via the signal processing unit 12. As a result, the voice message output unit 13 causes the speaker 14 to output a voice message such as a warning specified by the message selection unit 15.

[0017]

As described above, according to the present invention, regardless of the time, the season, the weather, the place of installation, etc., an unattended warning or attention can be transmitted to a passerby as a voice message. It is possible to disseminate warnings and the like while suppressing the above. As a result, it becomes possible to smoothly carry out the construction while ensuring the safety and convenience of passers-by. Further, the structure of the device is relatively simple and can be provided at low cost.

Further, since all the parts are housed in the triangular pole and the structure having no protrusions on the outside can be provided, it is convenient for transportation and storage. In addition, it is possible to provide a voice warning device which is comfortable even if it is arranged together with a general triangular pole, and which is rich in unexpectedness.
