Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, the status information sending method for the substation automation system of the present invention includes the following steps,
[0021] Step (A), constructing a status information file that records the current time section of the server. The status information file is constructed and formed by the server after receiving the control command issued by the client. The status information file includes the status data transmitted by the server. Data and analog data, the state data includes action signals, displacement signals and self-test signals; the analog data includes protection measurement signals, remote measurement signals and fault information signals, and the construction method of the state information file is as follows:
[0022] (A1), after receiving the control command sent by the client, the server performs status scannin...

The invention discloses a state information uploading method for a substation automation system. The method comprises the following steps: creating a state information file for recording a current time section of a server; sending a change report to a client by the server; after the client receives the change report, obtaining the corresponding state information file from the server by the client in a file transmission manner; and uploading the received state information file to a high level application program by the client. According to the state information uploading method for the substation automation system disclosed by the invention, the state information is transmitted in the file transmission manner, thereby avoiding the situation that when the client uploads the state information, the client needs to recombine the data information, ensuring that the state information obtained by the high level application program is original data provided by the server and improving the reliability of data transmission, and thus the state information uploading method has a good application prospect.
Description
technical field [0001] The invention relates to the technical field of power system data communication, in particular to a method for sending state information for a substation automation system. Background technique [0002] The current substation automation system used in the power system generally sends various status information from the server to the client through the report service in the station, for the client to display or forward through other communication protocols. In the existing application mode, when the client sends the status information to the advanced application program, it needs to reorganize the received status information so as to conform to the communication protocol standard used when forwarding. This reorganization and forwarding mechanism, to a certain extent, needs to process all kinds of original status information sent by the server. All kinds of original state information provided are consistent, resulting in lower transmission reliability, ...
