The remote control is a wireless transmitting device that encodes key information through modern digital coding technology and transmits light waves through infrared diodes. The light waves are converted into electrical signals by the infrared receiver of the receiver, which are decoded into the processor and demodulated to give corresponding instructions to control the set-top box and other equipment to complete the required operation. The principle of industrial remote control and normal remote control are similar, but they also have many differences. How to use the industrial remote control correctly? Let's read on to learn more.
This passage is going to talk about the followings of industrial crane remote control:
1) History of remote control
2) Introduction to industrial crane remote control
3) Remote control of industrial crane remote control should pay attention to the use of distance
Exactly who invented the first remote control is not available, but one of the earliest remote controls, is an inventor named Nikola Tesla (1856-1943) (he used to work for Edison, also known as a genius inventor) in 1898 when developed (U.S. Patent No. 613809).
Industrial crane remote control is a device used to control machinery from a distance. The modern remote control is mainly composed of an integrated circuit board and buttons used to generate different messages (definition of message in communication science: a set of interrelated meaningful symbols that can express a complete meaning of information. It is made up of buttons.
A new type of industrial crane remote control is coded and decoded using the latest technology to control the door pump solenoid valve in a flash-break manner to achieve the purpose of opening and closing. Used to remotely open and close the door to avoid the need to open the door each time. The main component of the transmitting part of the general ordinary industrial crane remote control is the infrared light-emitting diode. It is actually a special light-emitting diode, because its internal material is different from the ordinary light-emitting diode, so when a certain voltage is applied at both ends, it will emit infrared rather than visible light.
The main factors affecting the remote-control distance of the remote control are as follows.
Transmitting power: Although the transmitting power of industrial crane remote control is far, it consumes a lot of power and is prone to interference.
Receiving sensitivity: the receiver's receiving sensitivity is improved, the remote-control distance increases, but it is easy to be interfered with causing mis-operation or loss of control.
Antenna: using linear antenna and parallel to each other, the remote control distance is long, but it takes up a lot of space. If you want to increase the remote control distance, you can lengthen and straighten the antenna during use.
Height: the higher the antenna, the farther the remote-control distance, but it depends on the objective conditions.
Blocking: The wireless remote control uses the designated UHF frequency band, and its propagation characteristics are similar to that of light, it propagates in a straight line, and has a small bypass. The distance between the transmitter and receiver is affected by obstacles. If there is a wall in the middle, the range of the remote control will be greatly reduced. If the wall is made of reinforced concrete, the influence will be greater due to the absorption of radio waves by the conductor.
