Abstract
Description
Technical Field
[0001] The invention relates to the technical field of thermal analysis, and in particular to a task thermal analysis method for an automated rail distribution system for hospital materials. Background Art
[0002] New hospitals are increasingly using automated rail logistics equipment and systems to transport materials within the hospital, which has improved the automation of material distribution, improved distribution efficiency, and saved manpower. However, since rail logistics can only allow a single turnover box carrying materials to pass through the same section of track at the same time, when the volume of shipments is large and the traffic is heavy during peak hours, the processing capacity of a key hub node is insufficient, resulting in a backlog of turnover boxes on the track.
[0003] Through the thermal analysis method of the hospital material automated distribution system, the first is to intuitively reflect the thermal situation of the equipment flow task for the material sending department and equipment maintenance management, master the on-site box delivery situation, and adjust the box delivery strategy; the second is to view the thermal situation of the historical task flow through the adjustment of the time axis or automatic playback, and provide intuitive data support for the subsequent system optimization and adjustment. The existing equipment segment task quantity query method generally adopts the following steps:
[0004] 1. Manual query through SCADA data acquisition monitoring system and task query system;
[0005] 2. Select the equipment segment number in the conditions and select the time period for query;
[0006] 3. Manually count the task data queried from different equipment segments and different time periods;
[0007] Disadvantages of existing methods
[0008] The display of the task quantity by manually querying the data list is not intuitive. You can only query the task quantity statistics of one equipment segment in a time period at a time. If you want to view the task status of the entire system, you need to query and count multiple times, which is cumbersome. The non-graphical interface cannot intuitively reflect the on-site flow and thermal conditions. Summary of the invention
[0009] 1. Technical issues to be resolved
[0010] In view of the shortcomings of the prior art, the present invention discloses a task thermal analysis method for an automated rail distribution system for hospital materials, which reflects the actual capacity and flow of physical equipment through a graphical interface.

[0015] S3: After the SVG system bitmap obtains the flow data, it displays the thermal graphics on the bitmap according to the point data analysis.
