Embodiment Construction
[0104] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0105] The hot backup system of the present invention is based on the SOA model, and the SOA model is a service-oriented architecture model. The data storage of the present invention adopts the concept of cloud storage, and various monitoring data are distributed and stored in the host, slave, and cloud storage service end. WEB server and other databases, and then coordinate the work of each storage through the console system. The service is implemented by Microsoft's WCF (Windows Communication Foundation). The cloud storage server is composed of multiple WCF server modules. The host and slave of each substation monitoring system are It exists in the form of a WCF client.
[0106] When the program starts, the master and the slaves register with the console system respectively, including registration of the current substation and the status of the mas...
