Description

  The present invention relates to a structure of a signal controller for controlling a traffic signal.

  Examples of conventional signal controllers that include signal control electronic components as a unit include those shown in FIGS. 12 and 13, for example. That is, a plurality of signal control units are arranged in the vertical direction in a direction substantially perpendicular to the opening surface of the housing, and a connection terminal block for connecting the units and external wiring is provided.

  Among such conventional signal controllers, the signal controller for large-scale intersections requires, for example, 36 lamp outputs (6 units as signal lamp driving units). Further, the casing has, for example, a height of 1100 cm × a width of 400 cm × a depth of 300 cm and a weight of approximately 80 kg. This weight is about twice that of a general-purpose signal controller. Further, the capacity of the housing is about three times in volume ratio. Therefore, the conventional signal controller for large-scale intersections has the following problems.

(1) Since it cannot be assembled in the assembly line of a general-purpose signal controller, it must be assembled in a place different from the assembly line.
(2) Since the unit cannot be shared with the general-purpose signal controller unit, it must be managed separately.
(3) Transportation is difficult compared to general-purpose signal controllers.
(4) Workability on site is worse than that of general-purpose signal controllers.

In order to solve the above problems and the like, it is desired that the signal controller has a small casing.
As a proposal for reducing the casing of the signal controller, for example, there is a traffic control terminal device disclosed in Patent Document 1.

  This traffic control terminal device has been proposed for the purpose of accommodating a plurality of circuit boards in a smaller casing body. In this traffic control terminal device, a rotating unit for mounting a circuit board is rotatably housed in a housing body, and a connection terminal unit for connecting an external wiring to the circuit board mounted on the rotating unit It has. In the rotating unit, the arrangement direction of the circuit board changes depending on the state when the rotating unit is stored and the state where the rotating unit is rotated so that the circuit board can be taken in and out. As a result, the traffic control terminal device can accommodate a larger circuit board and can accommodate a plurality of circuit boards in a small casing body.

  The structure of the signal controller (10) of the item [4] is that the units (12, 13, 14, 15) are provided in the same size and shape even if they include different substrates that perform different controls. is there. Thereby, the space in a housing | casing (11) can be used efficiently.

  In the structure of the signal controller (10) of the item [5], in the unit (12), the chassis (120) constituting the unit (12) also serves as a heat sink and does not include a heat sink for heat dissipation. Therefore, the degree of freedom when the housing (11) is reduced in size is increased.

  According to the structure of the signal controller according to the present invention, the space of the wiring terminal block for external connection and the wiring space between the wiring terminal block for external connection and each unit are omitted, and the housing is miniaturized. Since the body is the smallest size that can accommodate all of the units that require the most units among the multiple types of signal controllers with different standards, the conventional large-scale intersection From a signal controller for large-scale intersections to a general-purpose signal controller conforming to a conventional standard can be manufactured on the same production line with a housing smaller than the housing used for the traffic signal controller.

Each time the selection button 224 is pressed, the selection item is changed, and the selection indicator lamp 221 that is turned on is moved accordingly.

  The setting button 225 may be pressed when the setting is possible and when the setting is finished. To confirm the setting, a setting execution button 226 disposed above the setting button 225 may be pressed.

  A pocket 227 made of a transparent material is provided below the setting button 225. This pocket 227 is for holding a chart or the like showing the steps of the signal lamp as shown in FIG.

  The outer door 20 is provided with a manual operation unit 201 below the center. The manual operation unit 201 is for manually operating the signal lamp. A small window is provided outside the outer door 20, and the signal lamp step (by pressing a button in the small window) The floor can be advanced manually.

  Here, a step or a floor means a unit of signal display. Description will be made by taking the intersection shown in FIG. 10 as an example. In FIG. 10, the road indicated by A is a main road, and the road indicated by B is a secondary road. A traffic signal for a vehicle passing through the main road A is a main road vehicle light 1, and a traffic signal for a pedestrian crossing the secondary road B is a main road pedestrian light 1P. A traffic signal for a vehicle passing through the secondary road B is referred to as a secondary road vehicle lamp 2, and a traffic signal for a pedestrian crossing the main road A is referred to as a secondary road pedestrian lamp 2P.

  FIG. 11 shows a traffic light control pattern at the intersection shown in FIG. In this control pattern, step 1 lasts 20 seconds, and during this time, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit in green, and the secondary road pedestrian lamp 2P and the secondary road vehicle lamp 2 are both red. Lights up.

  Step 2 lasts for 5 seconds, during which time the green light of the main road pedestrian lamp 1P flashes, the main road vehicle light 1 continues to turn on the green light, and both the secondary road pedestrian lamp 2P and the secondary road vehicle lamp 2 are red. Is lit. Step 3 lasts for 5 seconds, during which time the main road pedestrian lamp 1P is illuminated in red, the main road vehicle lamp 1 is continuously illuminated in green, and both the secondary road pedestrian lamp 2P and the secondary road vehicle lamp 2 are red. The signal is lit.

  Step 4 lasts for 3 seconds, during which time the main road pedestrian lamp 1P is illuminated in red, the main road vehicle lamp 1 is illuminated in yellow, and the secondary road pedestrian lamp 2P and secondary road vehicle lamp 2 are both red. The signal is lit. Step 5 lasts for 2 seconds. During this time, all of the main road pedestrian lamp 1P, main road vehicle lamp 1, secondary road pedestrian lamp 2P and secondary road vehicle lamp 2 are lit red. Therefore, in steps 1 to 5, both the secondary road pedestrian lamp 2P and the secondary road vehicle lamp 2 are lit red, and neither the vehicle nor the pedestrian on the secondary road B can travel.

  Next, step 6 continues for 15 seconds. During this time, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit red, and both the sub road pedestrian lamp 2P and the sub road vehicle lamp 2 are both illuminated. The green light is on. Step 7 lasts for 5 seconds. During this time, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit red, the secondary road pedestrian lamp 2P blinks green, and the secondary road vehicle lamp 2 The green light is still on.

  Step 8 lasts 5 seconds. During this time, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit in red, the secondary road pedestrian lamp 2P is lit in red, and the sub road vehicle lamp 2 The green light is still on. Step 9 lasts for 3 seconds, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit red, the secondary road pedestrian lamp 2P is lit red, and the secondary road vehicle lamp 2 is yellow. The signal is lit.

  Step 10 continues for 2 seconds. During this time, all of the main road pedestrian lamp 1P, the main road vehicle lamp 1, the secondary road pedestrian lamp 2P, and the secondary road vehicle lamp 2 are lit red. Therefore, in steps 6 to 10, both the main road pedestrian lamp 1P and the main road vehicle lamp 1 are lit red, and neither the vehicle nor the pedestrian on the main road A can travel.

  Step 1 in which both the pedestrian and the vehicle on the main road A can travel is 20 seconds, and step 6 in which both the pedestrian and the vehicle on the secondary road B can proceed is 15 seconds. The person and the vehicle are controlled so that they can travel for 5 seconds longer than the pedestrian and the vehicle traveling on the secondary road B.

  An output signal for controlling such a signal lamp is output from the terminal block 121 of the signal lamp driving unit 12 shown in FIG. The signal lamp drive unit 12 includes a chassis 120 to which the triac 122 and other electronic components are attached, a plate-like bracket 130 to which the electronic component triac 122 is attached and fixed to the chassis 120, and heat generated from the triac 122. And a heat radiating sheet 140 conducted to 120.

  The chassis 120 is made of a highly heat conductive material, and is made of, for example, aluminum. The chassis 120 is formed in a rectangular box shape having a predetermined thickness and long in the vertical direction, and has openings 150 at both ends in the longitudinal direction. The openings 150 at both ends communicate with each other internally.

  Further, the chassis 120 has at least three continuous surfaces that also serve as a heat sink. These three surfaces are, for example, the back surface and both side surfaces in a state where the signal lamp driving unit 12 is mounted in the housing 11 of the signal controller 10. As for the part which serves as this heat sink, the outer surface is anodized. Thereby, the amount of heat radiated from the chassis 120 to the outside increases.

  The triac 122 is attached to the bracket 130, and the bracket 130 is fixed inside the chassis 120. In this bracket 130, a triac 122 is fixed to an electronic component mounting surface 130b facing the inside of the chassis 120. Six triacs 122 are fixed to the illustrated signal lamp drive unit 12. Therefore, the number of outputs of the signal lamp driving unit 12 is six.

  A heat radiation sheet 140 is sandwiched between the fixing surface 130c opposite to the electronic component mounting surface 130b and the chassis 120. One side of the heat radiation sheet 140 is in surface contact with the fixed surface 130 c of the bracket 130, and the other surface is in surface contact with the chassis 120. The fixed surface 130c is substantially in surface contact with the heat dissipation sheet 140. The heat radiating sheet 140 is made of, for example, a material having high thermal conductivity including carbon fiber or a material having high thermal conductivity in which an inorganic filler is blended with silicon.

  Since such a signal lamp drive unit 12 does not have the heat sink that has been an obstacle to downsizing, it is easy to downsize the whole. Thereby, the housing | casing 11 which accommodates the signal lamp drive unit 12 can be reduced in size. In addition, since each signal lamp drive unit 12 is provided with a terminal block 121, the casing 11 has a wiring terminal block for external connection wired to each unit as provided in a conventional signal controller. Is not provided alone. Accordingly, a space for wiring from the wiring terminal block for external connection to each unit is not required, and the housing 11 can be reduced in size accordingly.

  Moreover, although the conventional wiring terminal block for external connection requires a large space, when the terminal block 121 is provided in each signal lamp drive unit 12 like the signal lamp drive unit 12, each terminal block 121 is Since the space occupied is small, the space can be used effectively, and the housing 11 can be downsized.

  In this way, the signal controller 10 includes all of the units 12, 13, 14, and 15 in accordance with the signal controller 10 that requires the most units 12, 13, 14, and 15 among a plurality of types of signal controllers. A housing 11 having a minimum size and shape that can be stored is used. Therefore, the casing 11 can be used in common for a plurality of types of signal controllers having different standards depending on the scale of the traffic signal.

Next, the effect | action by the structure of the traffic signal apparatus which concerns on this Embodiment is demonstrated.
When the signal lamp drive unit 12, the sensitive control unit 13, the push button control unit 14, and the interlock control unit 15 are attached to the signal controller 10, both the outer door 20 and the inner door 21 of the housing 11 are opened, Is fixed in place. As shown in FIG. 2, in the present embodiment, six signal lamp drive units 12 are mounted side by side on the upper stage, and the sensitive control unit 13 and the push button control unit 14 are mounted on the interlocking control unit 15 on the lower stage. .

  Each of these units 12, 13, 14, and 15 is provided with screw holes 123 in the upper and lower portions of the front side that is the front side when attached to the housing 11, so that the shaft portion of the bolt b is screwed into the screw hole 123. Further, the shaft portion may be threaded into a screw hole 111 formed in the mounting plate 110 on the housing 11 side. At this time, by bringing the lower end side surface of the chassis 120 into contact with the positioning spacer 112, the chassis 120 can be positioned and mounted at a predetermined mounting position.

  Accordingly, when the units 12, 13, 14, and 15 are positioned and attached, the opening 150 of the signal lamp drive unit 12 attached to the upper stage and the opening of the unit attached immediately below can be attached to a position where they communicate with each other. . As a result, air can flow inside the units 12, 13, 14, and 15 through the upper and lower units 12, 13, 14, and 15, so that heat is generated inside each unit 12, 13, 14, and 15. Can be reduced or prevented.

  The wiring connected to each signal lamp driving unit 12 from the outside may be directly connected to the terminal block 121 provided for each signal lamp driving unit 12. Since the terminal blocks such as the terminal block 121 are provided in each unit 12, it is not necessary to provide a wiring terminal block for external connection in the housing 11 separately from the unit as in the prior art. For this reason, the space for providing the wiring terminal block for external connection becomes unnecessary. Also, the wiring space between the external connection wiring terminal block and each unit can be omitted.

  As a result, the housing 11 can be reduced in size, so that the housing 11 can accommodate all of the units in accordance with the one that requires the most units among a plurality of types of signal controllers 10 having different standards. The shape can be limited. Therefore, the common housing | casing 11 can be used for the signal controller 10 from which the standards differed.

  In addition, the casing 11 is formed in a box shape that is long in the vertical direction, and each unit 12, 13, 14, and 15 is formed in a rectangular shape having a predetermined thickness and long in the vertical direction. . For this reason, the units 12, 13, 14, and 15 can be accommodated in the housing 11 in an arrangement in which the both ends are arranged vertically adjacent to each other in the vertical direction with both ends facing up and down and overlapped in a plurality of stages. Thereby, the flow of the air in the vertical direction inside each unit 12, 13, 14, 15 and the flow of the air in the vertical direction inside the housing 11 are not hindered. Therefore, it is possible to make it difficult for heat to be generated in each of the units 12, 13, 14, and 15.

  In addition, since the signal lamp driving unit 12 and the like serve as a heat radiating plate, the chassis 120 and the like constituting the signal lamp driving unit 12 and the like do not require a heat sink for heat dissipation. Thereby, the signal lamp drive unit 12 can be significantly reduced in size, and therefore the casing 11 to which the signal lamp drive unit 12 and the like are mounted can be further reduced in size.

Each of FIGS. 5 to 8 shows a second embodiment of the present invention.
In addition, the same code | symbol is attached | subjected to the site | part of the same kind as the signal controller 10 which concerns on 1st Embodiment, and the overlapping description is abbreviate | omitted.

  The signal controller 10A is a signal controller for general intersections manufactured using the casing 11 having the same size and shape as the casing 11 of the signal controller 10 in the first embodiment. There is no need for the number of lamp outputs as much as a signal controller for a scale intersection. For this reason, four signal lamp drive units 12 are mounted in the housing 11.

  In the signal controller 10 according to the first embodiment and the signal controller 10A according to the present embodiment, the shape of the mounting plate 110A due to the difference in the number of signal lamp driving units 12 and the arrangement position of the signal lamp driving units 12 Is the difference.

  As described above, the signal controller 10A for controlling the general-purpose traffic signal according to the present embodiment and the signal controller 10 for controlling the traffic signal for large-scale intersections are both conventional signal controllers for large-scale intersections. It is possible to use the same casing 11 that is smaller than the casing used in the above. Therefore, a plurality of types of signal controllers having different standards can be assembled on the same assembly line.

  Further, since the units of a plurality of types of signal controllers having different standards can be shared, the units can be easily managed.

  In addition, even a signal controller that controls traffic signals for large-scale intersections has a small casing, so it can be transported in the same way as a general-purpose signal controller and is easy to use on site. It will be as good as the signal controller.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention can be modified or added without departing from the scope of the present invention. Included in the invention. For example, the case 11 has been described with respect to the signal controller 10 that mounts six signal lamp driving units 12 and the signal controller 10A that mounts four signal lamps. Can also be used.

  The present invention is not limited to the one installed in the casing of the signal controller for controlling the traffic signal, but can be widely implemented as long as it is a device with a plurality of standards that houses the electronic component unit in the casing. .
