With the sustained and rapid development of China’s economy, people’s livingstandards are improving, then living garbage is at8%to9%annual increase. Soliving garbage’s handling has become the urgent problem that to be solved. Becausegarbage incineration power generation technology has a high degree of reduction,resource processing, completely harmless, conservation of land resources and otheradvantages,it will become the main way of garbage disposal. And as the coreequipment garbage incineration power generation feeding system, generationhandling cranes’ automation not only restricts the efficiency of garbage incineration,also impact on labor intensity. But the highly automated garbage handling cranesmajorities are derived from imports,it needs large investment and high operatingcosts. Therefore,how to improve the automation level of domestic garbage handlingcranes is the focus of our research.The paper in view of the fully automatic garbage handling crane control systemsand mainly studies and solves two problems: One is the control algorithm design ofthe automatic process of reclaiming the feeding point, and the second is the rationalplanning of speed in the process of cranes feeding. The two problems’ solve not onlycan ensure the crane automatically select grab points during the feeding process, butalso could enable the crane operate at the greatest possible speed without shaking andcollision. The main contents of this paper are as follows:First of all, introduce the background and significance of the paper; brieflydescribethe status of garbage handling cranesresearch; discusses the principles andcontrol of frequency control. And make a description of the different methods toanti-sway that existing in cranes. Then give the paper’s structure.Second, analysis the applications of semi-automatic control mode on the garbagecrane,thus propose a garbage handling cranes automatic feeding process.Third, design a positioning system on garbage handling cranes grab, combiningappropriate distance sensor and the district to get the garbage pit garbage surfaceheight information, and then propose a reclaiming strategy that based on crawledfrom the highest point of sub-regional. Fourth, taking the impact of intelligent active anti-roll device on the craneacceleration and deceleration process into account, and in order to achieve fastoperating speedduring crane feeding process and to avoid a collision of grabs, designa reasonable plan for crane and trolley’s maximum speed and their starting time.Finally, combination the automation and reliability requirements of cranes,design a specific program of garbage handling cranes electrical control system, anddescribe the main electrical components and gives selection methods.
