91.822 Application Field and Working Principle

91.822, also known as an Automatic Speed Regulation (ASR) system, is an important piece of communication technology that has many applications in industry, aviation and military. ASR is depends on two basic concepts: the measurement of speed and the regulation of the speed of the active element. By measuring and controlling the speed, it can be used for automation purposes, the most common being in the areas of industrial control, automotive and marine engineering.

The functionality of an ASR system is based upon the laws of inertia and motion. The basic principle of motion is that a moving body will remain in uniform motion until acted upon by an unbalanced external force. Inertia can be defined as the tendency of a body to remain at rest until an unbalanced external force is applied. This concept can be applied to the operation of an ASR system, the active element, or drive, being the moving body.

The principle of inertia and motion can be applied in two basic ways. The first is to measure speed and deceleration using a potentiometer. This potentiometer is typically located on the drive shaft of the motor or mechanism and measures the speed of rotation. When the speed falls out of the acceptable range, the potentiometer sends an electronic signal to the controller, which triggers the appropriate action.

The second application of the laws of motion is to control the speed of the active element. This is done by using an electronic circuit board, with a feedback control loop that continually monitors and adjusts the speed of the device. A PWM (Pulse Width Modulation) signal is used to regulate the current in the circuit, and a controller can be programmed to allow for different speed settings or profiles. The majority of ASR systems are programmed to maintain the desired speed with the minimum amount of variation.

ASR systems can be used for a wide range of tasks, such as automatic shut-off and speed control of motors, automating the adjustment of pressure valves, controlling the speed of industrial production lines, controlling the speed of engines, or the speed of pumps. It can also be used in aircraft, allowing for more efficient and accurate landing systems by automatically controlling engine speed and airspeed.

ASR systems have been used in military applications for a long time, for example, in cruise missiles, drones, and missiles. By controlling the speed of the missile, accuracy is improved, making it a very effective tool in both offensive and defensive operations.

In summary, 91.822 is an important communication technology that has a lot of applications in industry, aviation and military. It works on the principle of inertia and motion, and can be used for a wide variety of tasks, such as controlling the speed of motors, valves, production lines, aircrafts and missiles.
