Crane control system and implementation method thereof

Abstract

The invention discloses a crane control system and an implementation method thereof. The crane control system comprises a lifting mechanism controller, a cart mechanism controller No.1, a cart mechanism controller No.2, a trolley mechanism controller, a bridge controller, a slewing mechanism controller and a cab controller, wherein, each of the lifting mechanism controller, the cart mechanism controller No.1, the cart mechanism controller No.2, the trolley mechanism controller, the bridge controller, the slewing mechanism controller and the cab controller comprises an embedded module, and the structure of the embedded module is identical to the structure of a peripheral control circuit. In the invention, for the embedded modules applied to one crane are identical in hardware, the needed programs of applications with different functions for the crane are pre-cured in each embedded module; and corresponding programs can be directly called by a dial switch according to different functions of the applications so that one embedded module has various functions so as to provide convenience for prepare parts and save maintenance cost and time of a user.

Description

technical field [0001] The invention relates to a control technology of a hoisting machine, in particular to a hoisting machine control system and its realization method. Background technique [0002] At present, the control methods of cranes at home and abroad all adopt relay logic control and PLC control. Both control methods have advantages and disadvantages. [0003] Such as figure 1 As shown, the relay control method is characterized by low cost, complex control loop, high failure rate and frequent maintenance. This method mainly uses various types of relays to build logical control relationships. The cost is low, but it is prone to failures due to line damage or looseness. The failure rate is high and there are many failure points. The post-maintenance tasks of cranes using this control method are heavy. It is easy to affect the normal production of users. [0004] Such as figure 2 As shown, the PLC control method is characterized by high cost, simple circuit, an...

Problems solved by technology

Its cost is high. Although the circuit is relatively simple and the failure rate is low, once a system failure occurs, it must be resolved by professionals. It is mainly used in crane systems with complex control systems. The high cost and professional maintenance make many small and medium-sized enterprises reluctant to adopt it. PLC control system
