However, given that IEC 60870-5-101 is the predecessor of IEC60870-5-104, it is still the main backup channel in the current solution.

[0093] The database query display information includes: start time, end time, database table, substation name, dispatch point number (starting from 1), value, sorting column, sorting rule, operation waiting time, query results, total number of rows, maximum number of rows per page, number of pages, previous page, next page, query, export, clear current library table data, clear all database data.

[0094] The beneficial effect of the present invention is that, compared with the prior art, the present invention provides a method and system for simulating and parsing data on the server side based on the IEC 60870-5-101 protocol. Based on the IEC 60870-5-101 communication protocol, the server side device is simulated through the serial communication medium to perform information interaction. With a visual interface, the data source information can be modified in real time, and the client-related services can be responded to in real time, so that what you see is what you send; for the sent and received messages or manually input messages, the message parsing file is read according to the preset protocol, and the message is parsed in bytes, and the message is parsed and displayed visually; the test data can be queried; it is convenient for users to learn, understand, use and master the 101 protocol; it can also be used for verification of 101 protocol consistency, performance testing, etc.; it reduces the inefficient manual simulation message link and improves work efficiency. A lightweight database is used to store important data, such as remote signal displacement information, SOE information, remote control information, and remote adjustment information, for historical query. The IEC60870-5-101 standard information format is adopted, and data is transmitted to the 101 client in real time through a 101 client link corresponding to an independent thread mode to respond to the client business. Through visual data display, users can modify the data online in real time and control it in a timely and comprehensive manner. The data information on the interface is the information transmitted to the client, and the protocol message parsing interface allows users to learn, understand, master and diagnose the protocol in an image and in depth. The protocol parameter file and the view display file of the five remote meters can be read, including the remote signal meter, the remote measurement meter, the remote pulse meter, the remote control meter, the remote adjustment meter, and the message parsing file; a database is established, and the 101 client serial port channel and data interaction are dynamically established in real time. The data changes of the 101 server are timely transmitted to the protocol parsing layer through the signal slot mechanism, so as to be transmitted to the 101 client at the fastest speed to ensure the real-time nature of the data. The configuration information and the project can be saved and have strong readability, which reduces unnecessary repeated configuration work. The present invention has good scalability for functions and other protocols. It can run in multiple operating systems and has good portability.
