Abstract

The invention discloses a control method for eliminating logistics system node errors. The control method comprises the following steps that firstly, the arrangement deviation delta D1 of goods relative to the goods positions before goods taking is measured; secondly, the stop position C1=S0+ delta D1 of a shuttle vehicle on shuttle vehicle tracks during goods taking is controlled; thirdly, the arrangement deviation delta D2 of the goods relative to the shuttle vehicle is measured; fourthly, the stop position C2=T0+delta D2 of the shuttle vehicle on the shuttle vehicle tracks during goods delivery to a conveying line is controlled; fifthly, the arrangement deviation delta D2' of the goods relative to the shuttle vehicle after the shuttle vehicle takes goods from the conveying line is measured; sixthly, the arrangement deviation delta D3 of a carrying vehicle relative to the goods positions is measured; seventhly, the stop position of the shuttle vehicle on the shuttle vehicle tracks iscontrolled to be C3=S0+delta D2'+detal D3 when the shuttle vehicle conducts unloading towards the carrying vehicle; and eighthly, operation from the first step to the seventh step is repeatedly conducted till control is over. By means of the control method, the accumulative error of various conveying links in the conveying process is effectively eliminated, normal running of the whole system is ensured, and the operation efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of logistics storage, in particular to a control method for eliminating node errors of a logistics system. Background technique [0002] With the increasing cost of manpower and the increasing shortage of land resources, the automated logistics delivery system has the characteristics of automatic storage and handling of goods, automatic operation and centralized monitoring, statistical scheduling, and improved operating efficiency. It is more and more widely used in various industries. widely. [0003] In the automated logistics transportation system, positioning errors will occur in each transportation link, and these errors cannot be avoided. The longer the transportation link, the greater the accumulated error. After the accumulated error exceeds the allowable range of the automated logistics equipment, the automated logistics delivery system will experience abnormalities or failures, requiring manual in...
