Description

A TRAFFIC CONTROLLER
FIELD
[0001] The present invention relates to traffic signal controllers that control a plurality of signal groups that may be allocated to vehicle, public transport, bicycle and pedestrian traffic.
BACKGROUND
FIG. 2 of the accompanying drawings illustrates a typical traffic controller 31 , such as the Eclipse Traffic Controller manufactured by Tyco Traffic & Transportation. A traffic controller 31 may control multiple signal groups, including traffic signals 32. A signal group may consist of a set of lanterns (lights) which share the same colour sequence, and may control one or more movements such as left turn arrows, or a number of movements, such as left, right or through traffic flow. A traffic controller may communicate with a remote urban traffic control (UTC) centre (not shown). A traffic controller may drive plural signal groups and may allocate those groups as vehicle, arrow, public transport, pedestrian, and so on. Dimming of lamps may be implemented by time of day and verified by a light sensor (located in the cabinet) detecting day/night. Individual signal group outputs may be designated for nondimming, e.g. solenoids, changeable message signs or motors, when AC phase control is used. A traffic controller typically provide other functions as well such as (but not limited to) flashing, conflict
monitoring, lamp monitoring and vehicle detection. A traffic controller may also store intersection configuration data.
[0002] A traffic controller may include a cabinet within which there is mounted a module rack containing electronic modules that incorporates connections between electronic modules and field terminal blocks. These connections are provided by plugs, sockets and cables. Typically the electronic modules are logic modules, lamp control modules and traffic detection modules. The logic modules utilise the traffic flow measurements to control the sequencing of lights, and handle conflict management. The lamp control modules deliver power to the various lamps in the signal system, the traffic detection modules measure the presence of vehicles and pedestrians. [0003] To assemble a controller, a plurality of the electrical connections couple the electronic modules with field terminals such as lamps, switches and detectors including loops. Sockets are provided on the front panels of the electronic modules, and cable plugs inserted into the sockets. The ends of the cables, remote from the plugs, are connected by screw connections to the field terminals. The field terminal blocks connect to the various external detectors and switches, such as detector loops for detecting vehicles, and push buttons for pedestrians to request a green walk light to cross a road. Other field terminal blocks connect to traffic signals providing power to operate the signals.
[0004] The above construction of traffic controllers has a number of disadvantages including the time required to complete the abovementioned connections and the cost of the plugs, sockets and cables. More importantly, the method is prone to errors in that wrong connections are easily made. This results in the assemblies requiring testing before installation. This adds significance to the cost of the controllers.
OBJECT OF THE INVENTION
[0005] It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages.
SUMMARY OF INVENTION
[0006] There is disclosed herein a traffic controller including:
a mounting plate;
a back-plane printed circuit board mounted on the mounting plate and including a first set of plug portions and a second set of plug portions electrically connected to the first set of plug portions;
an electronic module having a set of plug portions engaged with the first set of plug portions so as to be electrically connected thereto; and
a field terminal block having a plurality of plug portions engaged with the second set of plug portions so as to be electrically connected thereto, and therefore electrically connected to electronic module.
[0007] Preferably, the plug portions are female or male plug portions. [0008] Preferably, the plug portions of the electronic module slidably engage the first set of plug portions.
[0009] Preferably, the plug portions of the field terminal block slidably engage the second set of plug portions.
BRIEF DESCRIPTION OF DRAWINGS
[0010] Preferred forms of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
[001 1] FIG. 1 is a schematic illustration of a traffic controller; and
[0012] FIG. 2 illustrates a typical traffic controller and traffic signal.
DESCRIPTION OF EMBODIMENT
[0013] In the accompanying drawing there is schematically depicted a traffic controller 10 located adjacent a road intersection 26. The traffic controller 10 would be located in a cabinet 27 having an access panel (door).
[0014] The traffic controller 10 includes a metal mounting plate 1 1 fixed to internal portions of the cabinet.
[0015] Attached to the mounting plate 1 1 is a back-plane printed circuit board 12 having a plug part 13 providing a plurality of plug portions 14. The plug portions 14 maybe male or female plug portions.
[0016] Engaged with the plug part 13, is a printed circuit board (electronic module) 15. In the attached drawing only one printed circuit board 15 is provided. However it should be appreciated that a plurality of the boards 15 may be provided, each of the boards 15 providing a particular function. For example, the boards 15 may include a logic module that controls the sequencing of the lights and handles conflict management. Another board 15 may control the lamps, while a further board may be a traffic detection module which measures the presence of vehicles or pedestrians. [0017] The printed circuit board 15 includes a base 16 upon which there is mounted a plurality of electrical components 17.
[0018] Also mounted on the base 16 is a plug part 18 connected to the components 17.
[0019] The plug part 18 includes a plurality of plug portions 19, that maybe male or female plug portions. The plug portions 19 slidably engage the plug portions 14 so as to provide for electrical connection between the printed circuit board 15 and the printed circuit board 12.
[0020] The printed circuit board 12 further provides a second set of plug portions 20 that are electrically connected to the plug portions 14.
[0021] Engaged with the plug portions 14 is a field terminal block 21 having a plurality of plug portions 22 engaged with the plug portions 20 so that the field terminal block 21 is electrically connected to the printed circuit board 15. The terminal block 21 provides for connection of various field terminals, such as lamps 23, detector loops 24 and/or switches 25, to be connected to the board 15. The terminal block 21 provides for the delivery of power to these various items, as well as to receive signals therefrom.
[0022] The plug portions 20 and 22 maybe male or female plug portions so that when the field terminal block 21 is engaged with the printed circuit board 12, there is sliding engagement between the plug portions 20 and 22.
[0023] The above described preferred embodiment has a number of advantages including reduced labour costs in respect of assembly, reduced cost of components utilised, elimination of incorrect couplings, and therefore making testing redundant.
