Problems solved by technology

In the case of large-scale welding machine networking, such as hundreds of units, if there is no communication with the computer for a long time, a large number of historical files will be stored in the memory of each welding power source, and these large number of historical files will be uploaded to the computer through the LAN , will cause the LAN network between the welding power source and the computer to be blocked
At the same time, limited by the computing performance of the computer, the files of some welding power sources cannot be received and processed normally

[0043] image 3 An overall flowchart of the first embodiment of the present invention is shown. The data communication method between the welding power source and the computer of the first embodiment includes the following steps.

[0044] Step 1: The welding power source requests to send file data (task request).

[0045] In this embodiment, as long as the welding power source 50 is connected to the network, it periodically requests the computer 60 to upload file data (file package). In this embodiment, the request cycle is set to be the same as the file generation cycle of the file generated by the welding power source, both of which are 3 minutes. It can be understood that the request period can also be set to be twice as long as the file generation period according to the actual situation. If within 3 minutes, received the upload permission reply of computer 60, then welding power supply 50 starts uploading; ask.

[0046] According to actual needs, instead of sending t...

[0124] For the sake of brevity, only the aspects of the second embodiment that are different from the first embodiment are described below.

[0125] Such as Figure 10 As shown, after the computer 60 performs task registration as in step 2 of the first embodiment, in step 3a, it is judged from all records of the same ID that the record that is registered later is selected as the current task, and the process is performed. .

[0126] As described in the first embodiment, the task registration in step 2 may generate multiple records for the same ID. When the computer 60 selects the current task, it compares the registration time or the number of files of each record with the same ID, and the record with the later registration time or the largest number of files is selected by the computer 60 as the current task for processing.

[0127] Simultaneously, since the record registered later includes the file serial number of the record registered earlier, the computer 60 has execute...

[0130] For the sake of brevity, only the aspects of the third embodiment that are different from the first embodiment will be described below.

[0131] Figure 11 with Figure 12 A registration task flow 2a different from the registration task flow 2 in the first embodiment is shown. In step 25a, for the records that have been responded to, that is, the records being processed, it is judged whether an upload abnormality occurs. If there is an exception, delete the existing record and add the current upload request to the task list. If there is no exception, update the content of the existing record instead of adding a new record.

[0132] Specific as Figure 12 As shown, it is assumed that two task records with IDs 1 and 2 already exist in the task list of the computer 60 . Among them, the number of files recorded by the task with ID=1 is 300, and the registration time and execution time are T30 respectively, that is, it is in the unresponsive state. At this time, the fi...

Abstract

The present invention relates to a method for performing data communication between a welding power source and a computer, and belongs to the technical field of welding control. The method for performing data communication between a welding power source and a computer in the present invention comprises the following steps: a welding power source requesting to upload a file to a computer through an upload request; the computer performing task registration according to the upload request, and generating a task record in a task list, the task record comprising the ID of the welding power source; the computer selecting a current task to be executed from the task list, and sending an upload allowing reply to the welding power source according to the ID of the welding power source in a current task record; after receiving the reply, the welding power source uploading a file to the computer; and the computer receiving the file, determining whether the upload is completed, and if the upload is completed, cancelling the current task record, or if the upload is not completed, returning and waiting to receive the file. According to the present invention, file upload requests from a great number of welding power sources are queued through a task list, so as to avoid network congestion caused when a great number of files are synchronously uploaded.

Description

technical field [0001] The invention relates to a data communication method between a welding power source and a computer, in particular to a data communication method between a welding power source and a computer with high transmission reliability, and belongs to the technical field of welding control. Background technique [0002] With the development of digital control of welding power supply and Internet communication technology, welding power supply with networking function has appeared. This welding power supply uploads the welding parameters obtained by it to the computer through network communication. On this basis, there has been a method for the welding power source to automatically save the welding parameters to its own memory. Welding parameters are saved in the form of data files to storage media such as Flash and SD cards inside the welding power source. During the use of the welding power source, the welding parameters form data files in chronological order....
