Crane remote control system and control method thereof

Abstract

The invention discloses a crane remote control system and a control method thereof. The crane remote control system comprises a local remote control unit and a handheld remote control unit, wherein the handheld remote control unit comprises a microcontroller, a speed signal giving unit, a handheld remote control unit attitude detecting device and a handheld remote control unit wireless receiving and transmitting device; the local remote control unit comprises a local attitude detecting device and a local wireless receiving and transmitting device; and the handheld remote control unit attitude detecting device comprises a micro-electro-mechanical sensor gyro, an acceleration meter and a magnetometer. The microcontroller is used for simultaneously measuring and contrastively analyzing information of the handheld remote control unit and a controlled object, a direction control command can be automatically analyzed, and thus the target direction control on a signified crane hanger to move can be realized. Since the attitude information of the handheld remote control unit and the controlled target can be automatically analyzed for control, the quantity of keys of the handheld remote control unit can be reduced, the operation is simple, and no professional operator is needed.

Description

technical field [0001] The invention relates to a crane control technology, in particular to a crane remote control system and a control method thereof. Background technique [0002] Material handling plays a very important role in the entire national economy. It is very important to improve the production efficiency of lifting and transportation machinery, ensure the safety and reliability of operation, improve the level of automation and reduce the cost of material handling. [0003] The operator of the existing remote controller of the crane needs to distinguish the target position of the hoisting parts and the relative position of the crane mechanism at first, and then analyze and correspond to the direction of the rocker or the buttons in his own mind. Low, easy to misjudge and make mistakes; especially for cranes with frequent use and heavy workload or nuclear ring crane equipment with low directionality, the labor intensity of the operator is increased, and the possib...

Problems solved by technology

[0003] The operator of the existing remote controller of the crane needs to distinguish the target position of the hoisting parts and the relative position of the crane mechanism at first, and then analyze and correspond to the direction of the rocker or the buttons in his own mind. Low, easy to misjudge and make mistakes; especially for cranes with frequent use and heavy workload or nuclear ring crane equipment with low directionality, the labor intensity of the operator is increased, and the possibility of misoperation is increased. A large number of crane equipment damage or even mechanical accidents caused by misoperation

[0004] Chinese patent CN200820042427.8 discloses "A Gyroscope-Based Spatial Remote Control", which only reflects the position information of the remote control based on the direction of the perception axis on the screen through the cursor to realize the movement, positioning and positioning of the screen cursor. Selection, similar to the space mouse, is only suitable for controlling display terminals such as computers and televisions, and cannot automatically analyze the direction control commands based on the attitude information of the remote control and the controlled object, so the remote control cannot realize the pointing of the crane. directional control

[0005] Chinese patent CN201110096680.8 discloses "A Gyro Remote Control for Electric Scooter". The remote control has a built-in gyroscope to control the forward, backward, braking, steering, and speed of the scooter at an inclination angle, and the controlled scooter does not install posture. The detection device cannot automatically analyze the direction control command according to the attitude information of the remote control and the controlled object. The operator must distinguish the direction of travel of the scooter before operating, so it is impossible to realize the controlled device.

[0006] Chinese patent CN201110329178.7 discloses "Integrated Remote Control". The first working mode of the remote control is to generate corresponding control signals based on the moving speed and direction parameters of the remote control induced by the three-axis acceleration sensor and gyroscope to control the controlled The device does not detect the attitude of the controlled device, and cannot automatically analyze the direction control command based on the attitude information of the remote control and the controlled object, so the remote control cannot realize the direction control of the crane.
