The utility model discloses a crown block control system. The system comprises a controller, a remote control receiver and a plurality of frequency converters, the controller comprises a control module, and an equipment network module and a first Ethernet module which are connected with the control module; wherein the remote control receiver is connected with the equipment network module, each frequency converter is respectively connected with the first Ethernet module, each frequency converter is respectively and correspondingly connected with one corresponding motor, and the controller respectively controls the action of each frequency converter through the first Ethernet module so as to respectively control the action of each motor to realize the operation of the crown block. Due to thehybrid network mode, the signal is stable, the transmission speed is high, and the anti-interference capability is high; meanwhile, when a communication fault occurs, the fault is easy to detect andtroubleshoot, so that the fault can be handled in time; moreover, the faults of the devices do not influence each other, stable operation of the multifunctional crown block is ensured, device breakdown is avoided, production is further prevented from being influenced, and the multifunctional crown block has the advantages of convenience, practicability, low manufacturing cost and the like.
