Today, with the continuous development of science and technology, wireless remote control technology has been widely used. From satellites to home TVs and air conditioners, they all use remote control technology to operate. The development of remote control technology is considered a sign of modernization. It can fully liberate people from the cumbersome physical labor and control them from a long distance as they like. The development of wireless remote control technology makes people enjoy the charm of science. Remote control technology can reduce labor intensity, increase labor productivity, and improve operational safety. People pay more and more attention to the application of wireless remote control technology in industrial automation control.
Most of the wireless remote control transmitting methods used in daily life are infrared type. Because of its low cost, it is easy for people to accept. However, because this control method is limited by the transmission distance, direction and conditions, it is quite limited, and it is insufficient in the field of industrial wireless control. At present, remote control devices widely used in the field of industrial wireless control are mainly in the form of wireless signal transmission.
The following is a brief introduction to the characteristics and advantages of the industrial wireless remote control system for cranes.
The wireless remote control system for cranes must have the following characteristics.
Once the remote control system fails, it will affect the normal operation of production. Therefore, the remote control system and the remote control system hardware must have a high degree of reliability. The receiving system protects the zero position before the operation of each group of numbers received during the receiving process. Before operation, all operating handles are required to be inspected according to the code. If an error code is recognized, it will wait for the next set of data zero position before sending the operation command. Zero position protection code during operation. If no continuous data code is detected at this moment, it will start the program before it can operate again.
The remote control system is the control device of the hoisting machinery. If the action is wrong, an accident of physical damage or personal injury will occur. Therefore, the 100% safety of the remote control system must be ensured, and the operator should be able to directly carry out emergency stop and automatic emergency stop of the system. The operator can independently operate the crane remote control in a convenient and safe location, which greatly reduces the chance of accidents. Moreover, the channel and password of each remote control are different, and multiple lifting equipment can work at the same time on the same occasion without affecting each other.
Wireless crane remote control can not be interfered by electromagnetic clutter of electric welding, electric furnace and crane inverter, etc., and can be used in a small area at the same time without interfering with each other.
The wireless crane remote control must have strong dust-proof, gas-proof, oil-proof, and shock-proof performance.
The launching system is carried and operated by the operator, so the wireless remote control should be small, light and easy to carry.
Crane wireless remote controls are widely used in single-beam and double-beam cranes, jib cranes, port cranes, gantry cranes and other equipment.
