According to the information of the China National Intellectual Property Administration, Henan Weihua Heavy Machinery Co., Ltd. has obtained a patent named "centralized controller of hoist crane", the authorization announcement number is CN121202007A, and the application date is October 2025.
The patent abstract shows that the invention discloses a centralized controller for a hoist crane, which relates to the field of crane operation control and includes a main control unit; The main control unit is respectively connected to the switch input/output unit, analog acquisition unit, encoder acquisition unit, RS485 communication unit, and Ethernet communication unit; The switch input/output unit is used to receive and output switch signals to achieve basic operation control; The RS485 communication unit and Ethernet communication unit are used to achieve information exchange with external devices. The centralized controller of this hoist crane integrates traditional decentralized relay/PLC control and independent functional modules into one through the integration of main control, switch input/output, analog acquisition, encoder acquisition, and two types of communication units, effectively solving the problems of poor module compatibility, complex wiring, and low integration among different manufacturers; Centralized management of crane operation has been achieved, improving system stability, safety, and scalability.
