Direct digital control systems use computers to automatically control processes based on certain conditions. They are commonly used in building automation, HVAC, and safety instrumented systems. These systems rely on data collection and processing to make necessary adjustments and can communicate with remote locations for faster control.
Direct digital control usually refers to a system in which a digital device such as a computer automatically controls some process based on certain conditions. There are many applications for direct digital control, many of which are related to building automation or HVAC systems. In general, these types of systems include multiple components controlled from a central location.
To carry out whatever tasks the system was created to maintain, it may rely on data collection and processing before changing conditions or attempting to meet certain specifications. For example, a direct digital control system intended to monitor and maintain a certain temperature and air pressure within a building may monitor various factors. If the temperature drops below acceptable levels, direct digital control systems can make the necessary adjustments, whether those adjustments involve turning on more radiators or encouraging air circulation by activating a series of fans and room ducts. ‘air.
Many security systems can also benefit from the technologies offered by direct digital control. For example, a safety instrumented system might monitor the pressure at the wellhead of an oil well and take action if that well’s pressure exceeds what is considered safe. This type of application shows the advantage of this type of control, because a system built to monitor safety can be able to detect malfunctions long before human intervention is possible. Just like industrial control systems, this type of control can be essential for high-risk jobs like drilling and oil extraction.
One of the most common applications for direct digital control is in HVAC systems. These systems enter the sometimes complex settings needed to heat an entire building or complex of buildings using a single energy source based on relatively simple user input. For example, you can type a desired room temperature into a thermostat and have the direct digital control system maintain that temperature almost indefinitely. As computers and processing technology improve, the possibilities for many of these systems can improve as well.
Building automation systems, HVAC, safety instrumented systems and many other types of direct digital control are possible in large part thanks to data communications and microprocessor technologies. Not only do devices that maintain control over something work faster and more efficiently, but they can also communicate with remote locations such as a home computer or central monitoring facility. Having data communicated faster between the many components of a system means faster control and quicker configuration of the correct parameters.
