Description

Technical Field

[0001] The present invention relates to the technical field of crane control, and particularly to a control expansion board connected to the Ethernet of an industrial remote controller. Background Art

[0002] When general bridge and gantry cranes are transformed for the project of unmanned operation in the driver's cab, the industrial remote control mode is used. The control lines connecting the output of the remote controller to the crane control cabinet have information such as emergency stop and gear positions. It is necessary to additionally add external relays to perform logical combination of the gear positions and control contactors to drive each mechanism to operate. After statistics, taking the control of three mechanisms as an example, when using relay combination, more than 30 intermediate relays need to be added. The external expansion increases the complexity of the circuit and occupies a relatively large space size. At the same time, most of the connection parts of the control lines are connected and fixed by crimping or spot welding. The loosening of the connection points during use will affect the stability of the circuit connection. Therefore, it is very necessary to design a control expansion board connected to the Ethernet of an industrial remote controller, with an ARM single-chip microprocessing chip as the core, to provide a more simple Internet connection solution, enabling the control expansion board to have network access capabilities and being able to obtain the output information of the receiver in real time during use.

At the same time, the connection ring and the docking head are elastically supported by the support spring, replacing the traditional fixed connection methods such as crimping or spot welding, and ensuring the stability of the circuit connection.
