  • Control apparatus for network traffic light
    Patent number: 5309155
    Abstract: A control apparatus for a network traffic light is provided with a main control device, a lamp control device, and a pair of power transmission lines connected between the main control device and the lamp control device in a ring-shaped fashion to carry the control signals which control each lamp set at an intersection. In this way, the layout engineering is simplified, and thus its cost is reduced. The ring-shaped layout permits the network traffic light to sustain its operation even if some of its lines are broken during road works. Maintenance of the control apparatus is also easy and fast.
