The invention discloses a control system for a garbage grab crane, which belongs to the field of automatic control of garbage processing equipment. The system includes: electrical transmission subsystem, PLC control subsystem, linkage operation console and weighing subsystem, the electrical transmission subsystem, linkage operation console and weighing subsystem are respectively connected with the PLC control subsystem; also includes: grab coordinate level The positioning subsystem is connected with the PLC control subsystem, and is used to detect the position of the large and small trolley traveling mechanisms of the garbage grab crane, and send the position detection results to the PLC control subsystem, so that the PLC control subsystem can send information to the PLC control subsystem according to the position detection signal. The electrical drive subsystem sends control commands to control the garbage grab crane. The system realizes the accurate detection of the position of the large and small trolley traveling mechanisms of the garbage grab crane by setting the grab coordinate type horizontal positioning subsystem, which not only improves the accuracy of control, but also improves the degree of automation of control.
Description
technical field [0001] The invention relates to the field of automatic control of garbage processing equipment, in particular to a control system used on a garbage grab crane. Background technique [0002] At present, the automatic control system of the garbage grab crane basically adopts the control method of "operation linkage platform + PLC + frequency converter speed control device". The operator is in the driver's cab above the garbage pit, and through the operation of the rocker and buttons on the linkage table, the tasks of feeding, transporting, mixing, and stacking of garbage in the pit are realized. This control method can basically meet the technical requirements of the garbage grab crane. Disadvantages: (1) There is no accurate position detection for each walking mechanism of the garbage grab crane, and the positioning switch is only set at some specific positions, and all working conditions are completely controlled by the operator. Manually completed by person...
