Exemplary applications
As shown in fig. 1, an embodiment of the present invention provides a method for automatically resuming transmission of client data after a network outage, specifically a method for automatically resuming transmission of an image after a network outage of an endoscope image workstation, including:
the data collected by the endoscope image workstation are stored in a local disk;
an SQLite database is established and used for storing structured data corresponding to the data, the structured data is shown in figure 2, and the structured data and the data of the local disk for storing the cancer establish a corresponding relation through a storage path;
the SQLite database is scanned through a real-time starting thread, and whether structured data are not uploaded to a server is judged;
if structured data are not uploaded to the server, searching data stored in a local disk corresponding to the SQLite structured data, and starting the operation of uploading the server;
and after the data are uploaded to the server, deleting the data stored in the local disk and the structured data corresponding to the data.
As shown in fig. 3, in this process, the network connection status of the endoscope image workstation and the server can be monitored simultaneously by threads, and there are three cases: in the first situation, if the endoscope image workstation is connected with the server and structured data are not uploaded to the server, searching the data corresponding to the structured data according to a path associated with the structured data and starting the operation of the uploading server; in the second situation, if the endoscope image workstation and the server are in a disconnected state, the uploading server operation is not started, and the network connection state operation of the endoscope image workstation and the server is monitored by repeated threads; and in the third situation, if the endoscope image workstation is connected with the server, structured data are not uploaded to the server, and structured data are not uploaded to the server, the uploading server operation is not started, and the SQLite database operation is repeatedly started.
Another possibility exists, the thread monitors the network connection state of the endoscope image workstation and the server, the thread only automatically starts the operation of the scanning SQLite database, under the condition that the network connection state of the endoscope image workstation and the server is not known, the thread starts the operation of the scanning SQLite database, finds that structured data is not uploaded to the server, searches for stored data corresponding to the structured data according to a path related to the structured data, starts the operation of the uploading server, and deletes the data stored in a local disk and the structured data corresponding to the data after the data is uploaded to the server if the endoscope image workstation and the server are in the network connection state; if the endoscope image workstation and the server are in a network disconnection state, the data are not uploaded to the server, the situation that the server is excessively occupied can occur, and resource waste is caused.
