It is the front view which showed the internal structure of the traffic signal controller of a state except the operation part panel based on this embodiment. It is the figure which expanded and showed area | region A1 of FIG. 1 based on this embodiment. It is the figure which expanded and showed area | region A2 of FIG. 2 based on this embodiment.

  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings.

  FIG. 1 is a front view showing an internal structure of a traffic signal controller 10 according to the present embodiment. FIG. 2 is a front view showing a state where the operation unit panel 40 is removed from the traffic signal controller 10 of FIG. In FIG. 2, the operation unit panel 40 is shown opened by a broken line for convenience. FIG. 3 is an enlarged view of the area A1 in FIG. FIG. 4 is an enlarged view of the area A2 in FIG.

  In the traffic signal controller 10, a mother board 12 is attached to the back part of the housing 11 on the back side. Here, the mother board 12 is arranged in the vicinity of the approximate center in the vertical direction.

  An interface board 13 is attached to the upper part of the mother board 12. The interface board 13 is a board having predetermined terminals for connecting a vehicle detector or the like.

  A lamp opening / closing unit 30 and a control power supply unit 37 are attached to the lower side of the interface board 13. Here, vertically long first to fourth lamp opening / closing units 31 to 34 having a predetermined depth are arranged side by side in the horizontal direction. When the first to fourth lamp opening / closing units 31 to 34 are not distinguished, they are referred to as lamp opening / closing units 30. The control power supply unit 37 has a vertically long shape having a predetermined depth similar to that of the lamp opening / closing unit 30.

  The lamp opening / closing unit 30 is a semiconductor relay unit that turns on / off the signal lamp. The lamp opening / closing unit 30 includes a lamp color monitor 35 provided on the upper side and a lamp connection terminal block 36 provided on the lower side of the lamp color monitor 35. The lamp color monitor 35 displays which signal lamp is lit on the LED monitor. The lamp connection terminal block 36 is an interface for connecting a signal lamp.

  A main power switch 21, a lamp switch 22, a relay terminal block 23, and an input / output terminal block 24 are provided below the lamp switch unit 30 and the control power supply unit 37, that is, near the lower side of the casing. They are arranged side by side. The area below the relay terminal block 23 and the input / output terminal block 24 is a work space used for traffic signal installation work or the like, and is required for quick and smooth installation work.

  The lamp switch 22 is a switch for turning on / off all connected signal lamps. The relay terminal block 23 is a terminal for internal wiring. The input / output terminal block 24 is a terminal for external wiring.

  The operation unit panel 40 is a panel that can be opened and closed, and includes a control unit 41, a display unit 42, and a displayed floor nameplate 43.

  The control unit 41 is a button for setting the display time of the signal lamp, etc., and is provided in a plurality in the horizontal direction in the upper region of the operation unit panel 40. The display unit 42 digitally displays the display time of the blue signal, the yellow signal, and the red signal, and is provided on the control unit 41.

  In the vicinity of the lower outer edge of the operation unit panel 40, a displayed floor nameplate 43 is attached. The displayed floor nameplate 43 indicates the lighting order of the signal lamps.

  Here, the first to fourth lamp opening / closing units 31 to 34 are mounted in a horizontal row, but the length of the operation unit panel 40 in the vertical direction extends to the upper end of the lamp opening / closing unit 30. The front face of the lamp opening / closing unit 30 can be seen even when the operation panel 40 is closed. In particular, even when the lamp color monitor 35 is in a state in which the operation unit panel 40 is closed, it is visible. That is, an operator who performs maintenance or the like can check the display state of the light color monitor 35 without opening the operation unit panel 40. That is, the lighting state of the signal lamp (lamp color monitor 35) and the lighting time (display unit 42) can be confirmed at the same time. In addition, since the current display nameplate 43 is attached immediately above the light color monitor 35, the light color monitor 35 and the current display nameplate 43 can be confirmed simultaneously.

  As a result, the operator hardly needs to open and close the operation unit panel 40, the installation work and maintenance / efficiency of the traffic signal controller 10 are improved, and the working time can be shortened. In particular, the maintenance and the like of the traffic signal controller 10 must be performed reliably in a short time from the viewpoint of safety and smoothness of traffic flow. Therefore, the traffic signal controller 10 can ensure a safer traffic flow.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of these components, and such modifications are also within the scope of the present invention. For example, a predetermined panel that covers the front surface of the lamp opening / closing unit 30 may be provided below the operation unit panel 40 in addition to the operation unit panel 40. By opening the panel and operating the operation unit panel 40 in a closed state, the same effect as in the above embodiment can be obtained.
