摘要： A method of operating a transport system, in particular a multi-carrier system, which comprises a plurality of linear motors, which are arranged in a row and have a guide track, and a plurality of transport elements that are movable along the guide track by means of the linear motors, has the following steps:
generating a travel job for a first one of the transport elements for travelling along at least a part section of the guide track,
generating a first movement profile of the first transport element for the travel job based on predetermined movement characteristic values,
matching the first movement profile with a second movement profile of a second transport element directly in front of the first transport element and determining whether a predetermined minimum distance between the first transport element and the second transport element is fallen below during the execution of the travel job,
updating the first movement profile to maintain the minimum distance if it has been determined that the minimum distance is fallen below, and controlling the linear motors to move the first transport element in accordance with the first movement profile.-

摘要： A method serves to operate a transport system, in particular a multi-carrier system, that comprises a plurality of linear motors that are arranged in a row and have a guide track, a plurality of transport elements that can be moved along the guide track by means of the linear motors, and a plurality of stations along the guide track, wherein each of the transport elements is associated with one of the stations. The method has the following steps:
generating an instance for each of the transport elements,
generating a list for each of the stations, wherein the instance for each of the transport elements associated with the respective station is associated with the list, and wherein, within the respective list, the instance of each transport element is linked to the instance of the transport element directly ahead of the observed transport element and to the instance of the transport element directly behind the observed transport element,
transferring a transport element from a first station to a directly following second station and inserting the instance of this transport element into the list of the second station if a transport job that goes beyond the first station is present for the transport element,
wherein the transfer of the instance takes place in an event-controlled manner and independently of a transfer point if a predetermined transfer condition is fulfilled, and
controlling the linear motors to execute travel jobs of the transport elements.
