A power information monitoring system and its wireless networking method

Abstract

The invention relates to an electric power information monitoring system and a wireless network method thereof. The electric power information monitoring system comprises a communication terminal, an access device, core network, a monitoring system primary station, a network management system and an operating floor. The communication terminal is upward connected with the access device and is communicated with the core network through the access device to set up wireless channels of data transmission; the communication terminal, the access device and the core network are respectively connected with the network management system, and on-line management of a device of the electric power information monitoring system is achieved through the network management system; the monitoring system primary station and the operating floor are respectively connected with the core network, and the core network uploads monitor message to the monitoring system primary station which does information processing. By fully using an existing 230 megahertzs frequency range authorization frequency point and drawing lessons from a carrier aggregation technology of a fourth-generation (4G) mobile communication long term evolution (LTE) technology, broadband transmission of discrete narrow-band is achieved; meanwhile by selecting and using the electric power information wireless monitoring system special for low-frequency stage construction, the electric power information monitoring system and the wireless network method thereof can be more favorable to establishment of a 'low cost and wide coverage' electric power information monitoring system.

Description

technical field [0001] The invention relates to the field of wireless technology networking, in particular to a power information monitoring system and a wireless networking method thereof. Background technique [0002] In the current deployment of physical power grids, the communication methods used by the power information monitoring system mainly include: optical fiber, wireless public network, and micro-power wireless, etc.; when the amount of transmitted data is large, or where there is a need for video transmission, the optical fiber communication method is often used ;At the end of the monitoring system, various monitoring terminals (such as sensors, cameras and other on-site devices) are connected to the aggregation node by PLC, micro-power wireless, RS232, RS485 and other communication methods; the connection between the aggregation node and the monitoring system master station For communication, at present, wireless public network is mostly used for transmission, a...

Problems solved by technology

[0010] From the above analysis, it can be seen that the GPRS wireless public network cannot well meet the networking requirements of the power information monitoring system; considering the safe and reliable transmission of monitoring data, it should be combined with the geographical distribution and data flow characteristics of the monitoring system, as well as the resource status, to establish a dedicated network. wireless communication channel
