After that, the operation switches 20 of both signal indicators A and B are switched to the synchronous operation side, and then the switches 12 and 13 of the remote controller 9 are operated to set the display contents such as signal display color and display time. After the control units 4 of both signal display devices A and B have been read (transmitted to the other signal display device B via the cable 10), the synchronous operation switch 11 is operated to operate both signal display devices A. , B are operated synchronously. That is,
By operating the signal section operation switch 12, the lighting color of the signal display section 2 of both signal indicators A and B is sequentially switched to red and green, and the lighting display time of the switched lighting color is adjusted by the time adjustment switch 13.
Is operated to set a desired time and input to the control section 4 of each signal indicator. In this case, the information is displayed while checking the information display section 3 of the signal display device A of his own.

After setting the operation modes of the signal display section 2 and the information display section 3 of both signal indicators A and B as described above, the operation switch 11 of the remote controller 9 is operated to make them operate synchronously. The signal display unit 2 and the information display unit 3 of both signal display units are matched with the above-mentioned setting contents input to the control unit 4.
The LEDs 2a, 2b, 3a are used to display the traffic regulation of the oncoming vehicle. In addition, this synchronous operation is
It is possible to select manual or automatic with the operation switch 11. In the case of manual operation, the operation switch 12 switches the lighting color of the signal display section 2 of both signal indicators, and in the case of automatic operation, the operation switch 11 is changed. After setting to the adjustment side, the lighting color and lighting time of both signal indicators are set by the operation switches 12 and 13, and the operation switch 11 is automatically switched again to start the synchronous operation of the set contents. Both signal indicators A and B during setting
The signal display section 2 of is blinking red.

The remaining time of each signal indicator is displayed as
The countdown is started and displayed on the information display unit 3 with the sum of the other party's green signal time and both red signal times as the maximum value.
While the green light is on in the signal display unit 2, the information display unit 3
Is not displayed. These signal indicators A and B are shown in FIG.
As shown in FIG. 4, each of the connector 25 is connected with the advance notice display C, and a plurality of these advance notice displays C can be sequentially connected in series to display the same contents as the respective signal displays A and B. Can be displayed on the signal display unit 2a and the information display unit 3a. In this case, these notice display devices C
Only the information from the signal indicator is input, and the notice indicator C does not return the information to the signal indicator side.

Further, when the remote controller 9 is operated, if the connection of the communication cable 10 is insufficient or there is an error in the setting of the display contents, the communication error display LED is turned on. When the signals of the two signal displays A and B do not return to each other, the signal display unit 2 of both signal display units is in a red blinking state and the information display unit 3 does not display the remaining time. Being controlled within.

In the above traffic regulation display by both signal indicators A and B, the display time can be automatically adjusted by the timer circuit. In this case, a timer 7 (shown in FIG. 1) is connected to the connector 24 of either one of the signal indicators, and within a 24-hour period, for example, a time zone in which traffic congestion of the vehicle is expected is sought to reach that time zone. An electric signal of 0 or 1 is sometimes output, and the information is read by the control unit 4 and automatically adjusted to prolong the display time of the green signal on the traffic jam side. In accordance with this green signal, the red signal display time of the other signal display device is controlled by mutual information exchange by the control unit 4 of both signal display devices A and B as described above.

Further, instead of the timer, a vehicle detection sensor (not shown) may be connected to the connector 24, and the number of vehicles waiting for a signal may be detected by the sensor to alleviate traffic congestion. That is, infrared rays or ultrasonic waves are emitted from the sensor to detect vehicles waiting for a signal between roads up to a certain set distance, and the number of the signals is converted into an electric signal to be read by the control unit 4 of the signal display device. The display time of the green signal on the signal display portion 2 of the signal display device is increased.
This setting also sets the signal display time of both signal indicators A and B in accordance with the contents of the sensor as in the above timer.

CdS is used to detect a certain level of brightness (set by the resistance value), resistance-divide it, and convert it into an electric signal through a converter. The microcomputer of the control unit 4 reads this information and the surroundings If it is bright, the brightness of the LEDs 2a, 2b, 3a of both display units 2, 3 is increased, and if it is dark, it is decreased. In addition, when the brightness of the LED is reduced, the lighting time of the LED is shortened, and it is prevented that the display units 2 and 3 are brightened or darkened in a short time due to repeated bright and dark in a short time. Therefore, the microcomputer of the control unit 4 has a timer of 10 seconds, and it is set so that the above luminance switching is not performed unless the change in the same state continues for the time or longer.

Next, in the above embodiment, the information display section 3 is set so as not to be displayed while the green signal is being lit on the signal display section 2. However, as shown in FIG. In the synchronous operation of both signal indicators A and B, one signal indicator A
It is also possible to set the information display unit 3 to display an arrow indicating the traveling direction of the vehicle when the signal display unit 2 is green. In this case, the LED of the information display section 3 has a red LE
It is also possible to dispose D and make the arrow a green signal to guide the approaching vehicle according to the arrow while confirming the safety. This arrow signal is also displayed in the same manner as the arrow display in the above-mentioned single use of the signal display, in which the information display unit 3 is divided into, for example, three, and the arrow lengthens sequentially from one divided portion to the other divided portion. Is possible. While displaying the green color, the other traffic light B
In the same manner as in the above embodiment, the signal display section 2 lights up in red and the information display section 3 digitally displays the waiting time (minutes, seconds).

Further, it is also possible to display the remaining time and the directional arrows on the signal display unit 2. In this case, the LEDs other than the display unit are displayed in reverse or in a different color to display the time and the arrow. To be clearly recognized. Furthermore, even if some abnormality occurs in the signal display unit 2 during the synchronization operation and the blinking of red color is impossible, the information display unit 3
The red circle blinks.

As described above, according to the signal display device of the present invention, since the signal display portion and the information display portion are formed by arranging a large number of LEDs, the signal display portion and the information display portion should be used for a long period of time. It is not ridiculous, and maintenance and inspection can be made almost unnecessary. In addition, the brightness of the LED can be automatically adjusted according to the ambient brightness, and even in direct sunlight at daytime at nighttime. Also, the display signal can be clearly confirmed.

Furthermore, since the direction of travel of the vehicle can be indicated by an arrow by means of a large number of LEDs of the information display section, smooth traffic control can be achieved and the waiting time at the time of the red signal of the signal display section can be displayed in real time. Therefore, the irritation of the driver can be eliminated.

After the two signal displays of the present invention are installed at desired road length intervals, the information displayed by the signal display and the information display is displayed on the control section of these signal displays. When inputting, connect both signal indicators with a cable and connect a remote controller to one signal indicator to operate the remote controller, so that the signal display contents and display of both signal indicators can be easily and accurately performed on site. The time can be set, and by performing the synchronous operation after the setting, it is possible to immediately perform the traffic regulation display of the vehicle alternating movement.

The display contents can be set by the remote controller by connecting a remote control cable of an appropriate length to the remote control. Therefore, the worker can perform the operation in a safe place, and the setting is incorrect. If both signal indicators start to display incorrect signals, or if any abnormality occurs during use, it is possible to enable the abnormality display via the control unit of the signal indicator and always It is possible to display signals with high accuracy. Further, since a DC power source can also be used, it is possible to use it by connecting it to the vehicle battery or the like without the need to separately prepare a generator or the like.
