7. Automated Control
1. Provide an overview of Automated control.
Automated control is the machanised command of a task or several tasks. The machine that controls the commands and operations are most often computers using programs that provide instructions of how the output required based on the input instructions.
2. Provide an overview of Traffic Light sensing devices and relevant pictures (p. 260)
Traffic light sensors use computer tracking devices to carry out their operations. Input comes from sensors that are installed under the road that monitor vehicle activity. Cars that travel over the sensors is counted by the sensor and then the traffic signals are changed based on and to meet the changing traffic patterns on the road. The sensors are wired loops that contain an electromagnetic field that are linked to an electrical meter. Maintenance is needed for the traffic light sensors and when a sensor does become faulty it must be attended to. SCATS professionals are responsible for the repair of these sonsors in which they fix the problem via the system computer.
3. Provide an overview of actuators and sensors to open and close doors. Please add relevant pictures. (p. 261)
Automated doors that open and close are controlled by a sensor that detects movement in which the motors (as seen in the picture)then carry out the tasks of either opening or closing the door, allowing the person(s). to pass through. There are a range of sensors that are used on automatic doors including motion sensors that use infra-red beams of which detect when the beam is broken, pressure sensors that use under mats to measure weight placed on them. In the case of automatic doors, actuators are used to carry out the action needed that is in response to a signal given by the sensor.
