The invention provides a computer implemented method for test of a control system for a logistics system. The method comprises testing (TST1, TST2) one or more low level control (LLC) software parts by simultaneously emulating a high level (HLE) response, emulating a low level emulating (LLE) response, and interfacing (INF) said HLE and low level emulation LLE. The interfacing (INF) of the HLE and LLE, comprises two-way exchanging a plurality of parameters (P) indicative of items to be handled in the logistics system between the HLE and the LLE. With such interfacing of a HLE for testing of a high level control (HLC) software of the logistics system, and the LLE for, it is possible to provide a realistic test and tuning of LLC software parts, e.g. Programmable Logic Controllers (PLCs) code, before the physical elements of a complex logistics system is built, e.g. an airport baggage handling system. This can reduce time and costs involved in final testing and tuning of parameters in the LLC software parts on-site, when the total system has been built.

No: 16/973212 Application Filed: June 07, 2019 Assignees: BEUMER Group A/S (Aarhus N, DK) Claim: 1. A computer implemented method for test of a control system for a logistics system, the method comprising emulating a high level response of an overall layout of the logistics system for testing a high level control software for overall control of the logistics system, emulating a low level response of physical elements of the logistics system for testing one or more low level control software parts for control of physical elements of the logistics system, interfacing the high level emulation and the low level emulation, by two-way exchanging a plurality of parameters indicative of items to be handled in the logistics system between the high level emulation and the low level emulation, and testing one or more low level control software parts by simultaneously emulating said high level response, emulating said low level emulating response, and interfacing said high level emulation and low level emulation. Claim: 2. The method according to claim 1, wherein the plurality of parameters indicative of items to be handled comprises as least one parameter indicative of one of: a unique identity for each item, and a time stamp associated with location of each item in the overall layout. Claim: 3. The method according to claim 1, wherein the plurality of parameters indicative of items to be handled comprises at least one parameter indicative of one of: destination of the item, content of the item, and status information. Claim: 4. The method according to claim 1, wherein the interface is configured to allow real-time two-way exchange of at least three parameters unique for each items to be handled. Claim: 5. The method according to claim 1, wherein the low level emulation program code is configured to emulate electric inputs and outputs of the physical elements of the logistics system. Claim: 6. The method according to claim 1, wherein the low level emulation program code is configured to emulate response of a plurality of physical elements associated with a plurality of low level control software parts. Claim: 7. The method according to claim 6, wherein the interfacing further comprises emulating response of an interconnection between at least two low level control software parts. Claim: 8-9. (canceled) Claim: 10. The method according to claim 1, comprising simultaneously testing a plurality of low level control software parts. Claim: 11. The method according to claim 1, wherein the high level emulation and the low level emulation are executed on separate processors. Claim: 12-14. (canceled) Claim: 15. The method according to claim 1, comprising receiving a set of input data for a plurality of items originating from a real-life logistics system, and applying said set of input data to the high level control software. Claim: 16. (canceled) Claim: 17. The method according to claim 1, comprising visualizing to a user at least a part of the logistics system and at least one item being transported therein to a user along with said step of testing. Claim: 18. The method according to claim 1, wherein the one or more low level control software parts are Programmable Logic Control software parts or software parts for Field Programmable Gate Arrays. Claim: 19. The method according to claim 1, wherein the testing is performed in real-time or faster than real-time. Claim: 20. A computer system comprising at least one processor and a memory and being programmed for carrying out the method according to claim 1. Claim: 21. A computer program product having instructions which when executed cause a computing system to perform the emulating of a high level response, the emulating of a low level response, and the interfacing according to the method of claim 1. Claim: 22. The computer program product according to claim 21, being one of: a software product for a general computer, a server software product, and a plurality of separate software products configured for execution on separate processors. Claim: 23. A computer readable medium having stored thereon a computer program product according to claim 21. Claim: 24. Use of the method according to claim 1 for test of a control system for a logistics system being one of: an airport baggage handling system, a mail or parcel sorting system, an item or material storage facility, and a material conveying system. Claim: 25. A logistics system for handling items, the system comprising a plurality of physical elements comprising at least one conveyor section arranged to transport a stream of items, at least one induction arranged for transporting items to the at least one conveyor, at least a discharge arranged for discharging items from the at least one conveyor, and a control system for controlling the physical elements, wherein the control system comprises a computer system programmed to control the physical elements according to a high level control software and one or more low level control software parts, wherein said high level control software and one or more low level control software parts have been tested according to the method according to claim 1. Claim: 26. The logistics system according to claim 25 being one of: an airport baggage handling system, a mail or parcel sorting system, an item or material storage facility, and a material conveying system. Claim: 27. (canceled) Current International Class: 06
