Industrial Remote Control and Its Advantages

Remote controls are more common in life. Every household has a variety of remote controls. Unlike civilian remote controls, we know less about industrial remote controls.

Industrial remote control is a device that uses radio transmission to perform remote operation control or remote control of industrial machinery. The industrial remote control is composed of a handheld or waist-hung transmitter and a receiving device fixedly installed on the equipment. The operator inputs people's operation instructions into the transmitter through the operation panel of the transmitter, and then the transmitter digitizes the instructions After encoding and encryption, it is transmitted wirelessly to a remote receiving system, and the receiving system is decoded and converted before restoring the control instructions to realize the control of various mechanical equipment.

The accuracy, sensitivity, signal continuity, anti-interference, remote control distance, waterproof and dustproof, high and low temperature resistance, acid and alkali resistance and other technical parameters required by industrial remote controls are higher than civilian remote controls. Industrial remote controls The device can adapt to various harsh environments; these are the reasons why civilian remote controls cannot replace industrial remote controls.

Industrial remote controls are mostly used in industries that use cranes such as metallurgy, shipbuilding and container terminals, warehousing, machinery manufacturing, chemicals, papermaking, construction and engineering machinery, and allow it to achieve remote control operations. Its effective control range is any position with a radius of 100 meters or even thousands of meters, and it will not be affected by obstacles. The operator only needs to carry a lightweight transmitter, walk around freely and choose a safe visual position to operate, eliminating the previous Hidden accidents caused by unclear vision, restricted line control, harsh environment, or improper command and coordination. It can not only ensure safe operation but also greatly improve production efficiency.

What are the ADVANTAGES of industrial remote controls?
★ Reduce manufacturing and maintenance costs: The replacement of the cab with remote control systems has long been a reality and has become a standard production process.
★ Improve safety and reliability: Because the command link is omitted, misunderstandings caused by improper command can be avoided; the operator can operate from the command angle to see the situation of the hoisted items more intuitively, and avoid tower crane operation The insecurity of the operator in the cab in inclement weather, and the incorrect communication between the operator and the commander during high-altitude operations have caused unnecessary accidents.
★ Improve the operating environment: The operator can choose a safe angle to avoid operating positions with poor visibility and serious pollution; to prevent the operator from being harmed by harmful gases.
★ Save human resources: Take the bridge crane as an example, the operation, mooring, hanging and unloading can be undertaken by one person alone, without command.
★ Improve work efficiency: The operator makes independent judgments, and the accuracy and continuity of the operation are significantly improved than before; because it is not necessary to be restricted by the upper and lower cabs and braids (operating lines), avoiding the operator's high temperature in the cab High, low work efficiency caused by physical discomfort, so the morale and work efficiency of the operator are improved.

With the widespread application of industrial remote controls in all walks of life, its advantages have become more prominent.
