Radio Remote Controls for EOT cranes in India

 

What is radio remote control system?

 

When artificially generated radio waves are used to control any type of machinery or equipment wirelessly, such kind of a control system is called a Radio Remote Control.

It typically consists of a transmitter device which radiates data in the form of a radio wave in free space with the help of an antenna towards the receiver. The receiver then picks up this signal with an antenna and decodes the data. Radio remote control for eot cranes are completely wireless systems which can transmit and receive data over very long distances.

Working principle of overhead crane remote control systems

An Industrial Crane radio remote control system has two units i.e. transmitter and receiver. The transmitter is the hand-held remote control, which is portable.

Every push button switch on the eot crane radio remote creates a combination of data for the crane receiver. This data is first encrypted and is then transmitted to the receiver.                                       

As soon as the receiver gets the data, it decodes and decrypts the data and switches on an assigned relay which activates the desired switch in the EOT Crane Control Panel.

The communication between Anand Transmitter and Anand Receiver happens more than 10 times in a second.

Transmitter can continuously monitor many parameters of the the communication link such as : a number of attempts for successful transmission, received signal strength, Link Quality Indication, missed packets , etc.

Anand Transmitters and Receivers use Automatic Frequency Hopping technique to continuously change the transmission frequency to avoid interference from undesired radio signals and increase the safety of the crane.

Need for wireless remote controls

Typical radio remote control applications are

Mobile phones for voice transmission

Bluetooth devices

Wi-Fi for providing internet over radio

Walkie Talkie systems

Songs over (Frequency Modulated)FM Radio and AM (Amplitude Modulated) Radio

Satellite communication

Customized Joystick Remote Controls . Made in India. Joystick overhead crane remote control systems Manufacturer in Mumbai, Pune , Bangalore, Delhi , Chennai , Kolkata .

Auto Power Control

Industrial crane remote control system automatically adjusts transmit power. This save battery life of the remote control. Anand Remotes can be programmed to have an auto power control system where the signal power sent by the transmitter is reduced or increased according to the distance of the receiver from the transmitter. Minimum 6 Month Battery life Using the most modern microprocessors and advance radio frequency anand systems engineering guarantees that your batteries will last a long time. Anand Remotes Batteries last more than 1000 hours of use for a normal 8 hour shift. Radio Remote Goes to Sleep mode as soon as button is released and wakes up immediately on key press. Advance Radio Frequency Engineering uses least amount of radio power for signal to reach the receiver.

What are Radio Waves?

Each Object that we see with our eyes reflect light .

This visible Light travelling through space is vibrating at a particular frequency is called an electromagnetic wave . The complete electromagnetic spectrum consists of waves vibrating at different frequencies .

Electromagnetic waves in the frequency range of 10khz up to 300Ghz are categorized as Radio Waves and Micro Waves. At these frequencies Alternating current in a conductor can emit energy into free space as radio waves.

Radio waves don't require a medium to move as required by Sound waves. They are a naturally emitted by Stars, Other electromagnetic waves such as X-rays, Gamma Rays ,Visible Light only differ from radio waves in terms of frequency and wavelength.

How Radio Technology Works?

Signal Received or transmitted by Antenna

Once the antenna has picked up the signal ,a band pass filter only allows the desired frequencies to pass while attenuating other frequencies .

Since many different radio waves are traveling through air at a given point of time, the antenna must be tuned to receive waves at the required frequency.

For example , an antenna tuned to 2.4ghz frequency will have a very low return loss at 2.4ghz and will exhibit a very high return loss at other frequencies .

For a monopole or Dipole Antenna, the length of the antenna depends on the wavelength of the desired frequency.

λ = c/f

λ = wavelength

C = Speed of light

F = desired frequency
