The control of the Blade Gantry Transfer Vehicle is a comprehensive process involving multiple control methods and systems to ensure that the transfer vehicle can accurately and safely complete the blade transfer task.
First of all, in terms of basic operation control, the transfer vehicle is usually equipped with an operating console. This console can be a fixed console in the vehicle or a wireless remote control. The operator sends instructions through the console to control the basic actions of the transfer vehicle such as forward, backward, and steering. Inside the console is a control system based on electronic circuits, which converts the operator's operating instructions into electrical signals and transmits them to the power system and steering system of the transfer vehicle. For example, when the forward button is pressed, the signal is transmitted to the motor driver or hydraulic controller (depending on the power form of the transfer vehicle), thereby driving the wheels to move forward at the set speed and direction.
In terms of precise positioning control, many advanced Blade Gantry Transfer Vehicles use automated control technologies such as programmable logic controllers (PLCs). The PLC system obtains position information through various sensors installed on the transfer vehicle. These sensors include laser rangefinders, encoders, etc. The laser rangefinder can accurately measure the distance between the transfer vehicle and the surrounding fixed objects or target positions, and the encoder can monitor the rotation angle and number of turns of the wheel in real time, so as to calculate the travel distance of the transfer vehicle. The PLC performs calculations and judgments based on these sensor data, and then adjusts the running speed and direction of the transfer vehicle to achieve accurate positioning of the blades. For example, when the blades are transferred to the designated processing station, the PLC can accurately control the transfer vehicle to stop within millimeter-level accuracy.
For the control of the gantry on the transfer vehicle, including lifting and traversing operations. This part of the control also relies on the electric or hydraulic drive system. The operator adjusts the output power of the motor or hydraulic pump through the corresponding buttons or knobs on the console, thereby controlling the lifting and traversing speed of the gantry. In addition, in order to ensure the stability of the gantry during the lifting and traversing process, the control system also monitors the load condition and movement state. If there is an abnormal load change or motion jitter, the system will automatically adjust the drive power or take braking measures to prevent the blades from shaking or falling.
In addition, safety control is also an important part of the control of the transfer vehicle. The vehicle is equipped with an emergency stop button. Once an emergency occurs, the operator presses the button and the control system immediately cuts off the power supply, causing the transfer vehicle to stop all movements. At the same time, there are some safety protection systems, such as anti-collision sensors, which automatically slow down or stop when they detect that the transfer vehicle is about to collide with other objects to ensure the safety of the transfer process.
