Automation the rise of the machine

The theoretical understanding and application dates from the Automation the rise of the machine, and they are implemented in nearly all analogue control systems; originally in mechanical controllers, and then using discrete electronics and latterly in industrial process computers.

Sequential control and logical sequence or system state control[ edit ] Sequential control may be either to a fixed sequence or to a logical one that will perform different actions depending on various system states. An example of an adjustable but otherwise fixed sequence is a timer on a lawn sprinkler.

State Abstraction This state diagram shows how UML can be used for designing a door system that can only be opened and closed States refer to the various conditions that can occur in a use or sequence scenario of the system. An example is an elevator, which uses logic based on the system state to perform certain actions in response to its state and operator input.

For example, if the operator presses the floor n button, the system will respond depending on whether the elevator is stopped or moving, going up or down, or if the door is open or closed, and other conditions.

Relays were first used in telegraph networks before being developed for controlling other devices, such as when starting and stopping industrial-sized electric motors or opening and closing solenoid valves.

Using relays for control purposes allowed event-driven control, where actions could be triggered out of sequence, in response to external events. These were more flexible in their response than the rigid single-sequence cam timers.

More complicated examples involved maintaining safe sequences for devices such as swing bridge controls, where a lock bolt needed to be disengaged before the bridge could be moved, and the lock bolt could not be released until the safety gates had already been closed.

The total number of relays, cam timers and drum sequencers can number into the hundreds or even thousands in some factories. Early programming techniques and languages were needed to make such systems manageable, one of the first being ladder logicwhere diagrams of the interconnected relays resembled the rungs of a ladder.

Special computers called programmable logic controllers were later designed to replace these collections of hardware with a single, more easily re-programmed unit. In a typical hard wired motor start and stop circuit called a control circuit a motor is started by pushing a "Start" or "Run" button that activates a pair of electrical relays.

The "lock-in" relay locks in contacts that keep the control circuit energized when the push button is released. The start button is a normally open contact and the stop button is normally closed contact.

Another relay energizes a switch that powers the device that throws the motor starter switch three sets of contacts for three phase industrial power in the main power circuit.


Large motors use high voltage and experience high in-rush current, making speed important in making and breaking contact. This can be dangerous for personnel and property with manual switches.

The "lock in" contacts in the start circuit and the main power contacts for the motor are held engaged by their respective electromagnets until a "stop" or "off" button is pressed, which de-energizes the lock in relay.

Suppose that the motor in the example is powering machinery that has a critical need for lubrication.

In this case an interlock could be added to insure that the oil pump is running before the motor starts.Nov 16,  · To reduce the number of both false negative and false positive detections our automation pipeline uses a variety of tools and technologies to.

Automation the rise of the machine

The rise of the machine has proved a constant since the Industrial Revolution. However, acceleration in the pace of change today is primarily down to digitization, the 21st-century’s phenomenon.

Machine and deep learning technology mean clients benefit from optimized data management, reduced operational risk and a more robust audit trail. Should we be worried? Not yet, but almost no sector can remain immune to the rise of the machine. For CRE, the clever play is .

Rise of the Robots There’s some logic to the thesis, of course, and other economists such as Andrew (The Second Machine Age) McAfee have sided generally with Ford’s outlook.

The rise of the machines R obotic Process Automation is a game-changer for the way company processes are executed. Outsourcing Services revenues and contract lengths should fall and customer self-sufficiency increase. We see a $25/60bn hit to global Business The Rise of the Machines.
