The invention discloses a non-real-time online communication data acquisition system and method based on equipment model buffer. The system comprises a physical equipment module, a communication module, a model buffer module and an interface data display module connected in sequence; when the interface data display module initiates a communication request, the model buffer module distributes one model buffer for data interaction according to received model description; the model buffer is connected to the physical equipment module through the communication module according to a physical equipment address received from the interface data display module; an online communication link between the interface data display module and the physical equipment module is established; the communication link is disconnected after data acquisition is completed; and the model buffer module recycles the model buffer. According to the invention, the model buffer module is opened up when a process starts; furthermore, only the buffer having the maximal maintenance equipment number is necessary to open up; the buffer is released after the process is ended; therefore, the memory overhead of the system can be reduced; and the rapidity and the stability for system operation are increased.
Description
technical field [0001] The invention relates to a non-real-time online communication data acquisition system based on equipment model buffering, and also relates to a non-real-time online communication data acquisition method based on equipment model buffering, which belongs to the field of substation communication. Background technique [0002] At present, the technology development in the field of remote real-time monitoring of substations is particularly rapid. In these monitoring systems, interface devices consistent with the on-site physical equipment of substations are generally constructed (interface devices are used to display specific data of equipment, such as remote signaling, telemetry, remote control, remote pulse ), the interface device in the system monitors the on-site physical equipment in real time through the power system network, and when the monitoring personnel find an accident or failure, they will notify the maintenance unit to carry out maintenance. ...
