Radio Remote Controls

There are basically two different types of wireless remote control: radio remote controls and infrared. We use them for so many everyday procedures, but their most important applications are in those that take place in industrial settings. Due to advances in technology, radio remote controls are now creating advancements in industrial settings. Pumps, valves, and a variety of machinery can all be operated remotely.

Most who are involved in industry are more than familiar with remote control operations. And after all, the technology is, for most business owners, not as relevant as the results. With the progression of multiple formats of wireless capabilities, the business of radio remote controls is increasingly becoming a necessity rather than a futuristic luxury.

Digital Circuits and Radio Remote Controls

As those familiar with remote operations know, a digital circuit, consisting of ones and zeros, transmits repeatedly to the other end. This gives a simple negative or positive transmission. A series of negative and positive signals that matches the code set in the garage door, or house or car alarm, in the simplest level, and will enable the door to be opened.

The kind of radio remote controls used to operate machinery such as concrete pumps uses a more complicated format because a range of movement is required, rather than a simple yes or no format. To produce the signals that produce movement, a series of digital pulses is transmitted. This is known as "manipulator type" radio remote control.

Pulse Transmission and Radio Remote Controls

The method for triggering a range of different movements may involve changing the timing of the pulses involving, for example, sending the numerical value of an angle in the form of a binary number. A long series of different pulses will constitute the complete range of potential movement for a given remote controlled object. The manipulator type systems constitute industrial remote control that can be used for a wide range of industrial applications.

In the business end of the radio remote control setup, these sets of information are interpreted into a constant stream of data which produces the required movement. The potential for control of an object which is moving has vast implications for both safety and efficiency. More and more industrial businesses are employing remote control systems, and those are not, must begin to in order to stay at the front of the pack. Rather than being the wave of the future, radio remote control is the necessity of the present.

The viable operations of radio remote controls include opening and closing valves, operating industrial lifting equipment, remote controlled pumps, operating camera flash systems, and more. The advantages of using radio remote controls for such industrial applications include safety for personnel and accuracy of movement. Although using radio remote controls for such a wide range of purposes has only relatively recently developed, the concept of remote control has been with us for a long time.

Historically, the first time radio remote controls were used for a serious purpose was during World War II when the Germans used it to control motorboats to ram enemy shipping. Radio controlled bombs were also used by both sides during World War II. The first civilian use for radio remote control was the opening and closing of garage doors, introduced in 1940. Currently, this technology is being most widely developed by and for those engaged in industrial businesses.
