Abstract

PURPOSE:To realize the smooth guidance of a vehicle to meet traffic volume by fitting a timer in a receiver device so that signal lamps can be switched and the lighting hour can be adjusted. CONSTITUTION:The receiver devices 2, 3 are arranged respectively at the both ends of the regulated section of a road, and when a conductor pushes and operates one of switches SW1, SW2 of a transmitter device 1, receiving parts 23, 33 receive it, and specified relay circuits RL1, RL2 are formed, and switch control parts 26, 36 are interlocked, and the respective signal lamps 21a to 31b start to light. Besides, since memories 24, 34 store the specified relay circuits RL1, RL2 formed once, the same signal lamps continue to light continuously. After this, the lamps are automatic-controlled by a switching part 10 and the timer 25 fitted in the receiver device 2,and consequently, the signal lamps 21a to 31b of the respective devices 2, 3 repeat respectively to be switched on and out alternately. Thus, adaptability to changing traffic volume is improved.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a signal device used for guiding vehicles. In this case, there are two ways to guide the vehicle:

(A) Guidance method using guides A method in which guides are placed at both ends of the no-run area, and the guides guide the vehicle using hand signals from the guides.

(B) Method of guiding vehicles using traffic lights A method of guiding vehicles by installing traffic lights at both ends of the no-drive area and switching the signal lights indicating stop or drive-able at regular intervals.

<Problems to be Solved by the Present Invention> The conventional vehicle guidance techniques described above have the following problems.

(b) In the case of the guidance method using guides, it is necessary to deploy guides with a total distance of 2 Å or more on both sides of the impassable area.

This increases labor costs and leads to high guidance costs.

(b) In the method of using traffic lights, the switching time intervals of the signal lights are constant, making it difficult to switch the signal lights in response to traffic volume, which causes traffic congestion.

Furthermore, in places where general AC power is not available, not only is it impossible to install traffic lights, but even if power is available, power transmission cables exposed on the road are likely to break.

<Objective of the present invention> The present invention has been made in view of the above points, and is economical, allows smooth guidance of vehicles according to traffic volume, and can be used in areas without power transmission lines. Furthermore, it is an object of the present invention to provide a signal device used for vehicle guidance, which is free from any fear of power transmission cable cutting accidents.

<Configuration of the Present Invention> An embodiment of the present invention will be described below with reference to FIG. 1.2.

<B> Configuration of signaling device FIG. 1 shows an example of a signaling device according to the present invention.

The signaling device includes a transmitting device 1, first and second receiving devices 2.
It consists of 3.

Each device will be explained below.

<Mouth> Transmitting device The transmitting device 1 is a device that remotely controls the first and second receiving devices 2.3 wirelessly.

The radio waves used are in the 130 MHz frequency band.

Reference numeral 11 denotes a power supply unit, which can use a DC power supply with a small storage capacity such as a dry cell battery.

The transmitter 1 incorporates a plurality of sets of changeover switches SWI to SW3 in addition to an oscillator (not shown).

In this embodiment, a case will be described in which the changeover switch SWI means a switch for a combination of blue and red, SW2 means a switch for a combination of blue and red, and SW3 means a switch for a combination of red and red.

<C> First receiving device The first receiving device 2 has a function of receiving from the transmitting device 1, and includes red and blue signal lights 21a, 21b, and a power supply section 22.
, an antenna 23, a memory part 24 for storing signals received by the antenna 23, relay circuits RL1 to RL3, and a relay circuit RL for lighting the signal lights 21a and 21b.
4, the switching control unit 26, the timer 25, and the antenna 23
It consists of a switching section 10 disposed between the two.

[Power Supply Unit] The power supply unit 22 includes a lead battery 28 with a charging circuit 27.

It may also be used in conjunction with a general AC power source of 100 volts.

Since the charging circuit 27 is provided in the circuit, even a 40AH lead battery can be used continuously for at least 8 hours or more.

This is particularly advantageous when installed in a location where there are no power transmission cables.

[Receiving circuit 1 The first receiving device 2 includes multiple sets of relay circuits RL1 to R.
L3 is included.

In this embodiment, a case will be described in which RLI means a relay circuit for a combination of blue and red, Rb2 means a relay circuit for a combination of blue and red, and Rb3 means a relay circuit for a combination of red and red.

These relay circuits RLI to RL3 are in communication with a switching control section 26 forming a separate relay circuit RL4.

Furthermore, relay circuits RLI to RL3 formed alternatively
Based on this, the switching control unit 26 switches each signal light.

[Memory 1 Memory 24 contains relay circuits RL1 to RL formed by − degrees.
3 (memory circuit).

[Timer] The timer 25 has a function of connecting to the switching unit 107 and repeatedly switching the lighting of the signal lights 21a and 21b via the switching unit 10 after a set time has elapsed.

The range that can be set for the timer 25 is, for example, 30 seconds to 10 minutes for blue and red lights, and 15 minutes for both lights.
The time range is from seconds to 5 minutes, and these setting times can be easily changed.

One of the features of the present invention is that a timer 25 is built into the first receiving device 2 so that the signal lights 21a and 21b can be switched and the lighting time can be adjusted.

[Switching Unit] The switching unit 10 incorporates a plurality of sets of changeover switches SWI to SW3 similarly to the above-described transmitting device 10.

By incorporating the switching section 10 having a similar structure into the first receiving device 2, automatic control by the timer 25 becomes possible.

<2> Second receiving device The second transmitting device 3 has the same configuration as the first receiving device 2 described above except for the absence of the timer 25 and the switching unit 10, so the same parts are used in the first receiving device 2. A code with 30 added to the tens digit of the receiving device 2 will be given, and the explanation thereof will be omitted.

<Operation> Next, a method for guiding a vehicle using the above signal device will be described.

<A> First and second receiving devices 2.3 are installed at both ends of the restricted section of the guidance preparation road.
are deployed respectively.

<mouth> Start of guidance When the first and second receiving devices 2.3 are turned on, the red signal lights 21a and 31a of both receiving devices 2.3 are automatically turned on.

The guide then turns on one of the switches SWI of the transmitting device 1.
, SW2 is pressed, the signal is received from the transmitting device 1 by the receiving sections 23.33 of both the receiving devices 2.3, and specific relay circuits RLI, RL2 are formed.

When a specific relay circuit RLI, RL2 is formed, the switching control unit 26.36 depending on this relay circuit RLI, RL2.
The signal lights 21a to 31b start lighting in conjunction with each other.

Also, the memory 24.34 once formed the specific relay circuit RL1. Since RL2 is memorized, the same signal light continues to be lit.

From now on, the switching section 10 incorporated in the first receiving device 2 will be described.
As a result of automatic control by the timer 24, the signal lights 21a to 31b of each receiving device 2.3 alternately turn on and off.

The operator only needs to transmit the radio waves from the transmitter 1 for the first time, and then the first and second receivers 2.3 will switch to automatic control, so unless there are special circumstances, the guide should not continue to transmit radio waves from the transmitter 1. No need to send.

Note that during automatic control, it is naturally possible for an instructor to manually operate the transmitting device 1 if necessary.

<Effects of the Present Invention> Since the present invention has been described above, it has the following effects.

(A) By incorporating a timer and switching section into the receiving circuit, the lighting time of the signal light can be adjusted freely.

Therefore, the system can respond well to changing traffic volume, and is very useful in eliminating vehicle congestion.

<Mouth> By incorporating a memory circuit into the receiving circuit, the power consumption of the transmitting device is extremely low.

<C> Since fewer guides are required, personnel costs can be significantly reduced compared to conventional methods.

(2) Since automatic control of the signal device becomes possible, traffic guides can be protected from traffic accidents.

<E> Since it uses a lead battery with a charging circuit, it can be used in places without power lines.

(To) Power transmission cables are not required.

Therefore, it is easy to install and remove the signaling device, and there is no need to worry about cutting the power transmission cable as in the past.
