Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0046] This application provides a channel allocation method for power grid monitoring system based on server instance expansion, which can be applied to such as figure 1 In the power grid monitoring system shown, the system may include a scheduling unit, multiple remote terminal units (Remote Terminal Unit, RTU) and multiple server instances. Among them, the scheduling unit can be connected to multiple server instances; the remote terminal unit can collect data in the digital grid and transmit it to the server instance. For each RTU, in order to prevent data loss, the mai...

The invention relates to a power grid monitoring system channel distribution method based on server instance capacity expansion, and the method comprises the steps: determining a first remote terminal unit connected with a first server instance in response to a capacity expansion request sent by the first server instance; enabling the first remote terminal unit to be connected with the first server instance through a first standby channel, and to be connected with a second server instance through a first main channel; acquiring the access information from a third server instance, and determining whether the third server instance is successfully accessed or not according to the access information; when the access is successful, establishing a new first standby channel between the first remote terminal unit and the third server instance, and closing the first standby channel between the first remote terminal unit and the first server instance, thereby realizing automatic and reasonable scheduling of the data transmission channel, not only improving the scheduling efficiency, but also simplifying the operation, so the operation is more intelligent and simpler.
Description
technical field [0001] The present application relates to the technical field of digital grid, in particular to a channel allocation method and device for a grid monitoring system based on server instance expansion, a grid monitoring system, computer equipment and a storage medium. Background technique [0002] For the front-end system used for data collection in the digital grid, it often includes multiple remote terminal units (Remote Terminal Unit, RTU) and multiple server instances, wherein the RTU is responsible for collecting data and transmitting it to the server instance, for each RTU, in order to prevent data loss, often sets the main channel and the backup channel at the same time, and each RTU is connected to a different server instance through the main channel and the backup channel. [0003] However, when the server instance needs to be expanded, it is often necessary to manually schedule all data transmission channels, and the operation is cumbersome. Content...
