DSP-based automatic control system hardware platform of bridge-type crane

A DSP-based automatic control system hardware platform of a bridge-type crane comprises a DPS control module, a signal generating module, two signal isolating modules, a relay module, a sensor module, a wireless communication module and a power supply module. The DSP control module and the signal generating module can generate a pulse signal of a needed frequency as a control signal of the crane. One of the two signal isolating modules separates the relay module from the DSP control module, and the other signal isolating module separates the signal generating module from a controlled target. The sensor module can measure the position of the crane, the swing angle of a lifting rope, and the rotational speed of a motor. The DSP control module carries out data interaction with the sensor module and a host computer through the wireless communication module. The platform uses a control program and communication protocols developed on the DSP control module, achieves remote control of the bridge-type crane, and realizes swinging eliminating and positioning control of the bridge-type crane based on track planning. Experiment results indicate that the platform can obtain good control effect and has high practical application value.
