Embodiment Construction

[0029] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] A distribution automation communication method based on code division multiple access technology is figure 2 Realized on the distribution automation system shown. The distribution automation system consists of distribution automation (DAS) host, local area network, CDMA gateway, optical fiber network, interworking function module (IWF), switch, wireless base station, CDMA PAD (CDMA user group disassembly device) and telecontrol terminal (RTU ) connection composition. The distribution automation (DAS) host is connected to the CDMA gateway through the local area network. On the one hand, the CDMA gateway is connected to the wireless base station through CDMA. The terminal is connected to the wireless base station through the CDMA PAD to realize the communication function between the distribution automation (DAS) host and the remote cont...

Abstract

The invention relates to a distribution automation communication method based on code division multiple accesses technology. The distribution automation communication method based on code division multiple access technology is characterized in that the method includes a downstream communication method from a distribution automation main engine to a remote terminal unit and an upstream communication method from the remote terminal unit to the distribution automation main engine; the distribution automation main engine is connected with a CDMA gateway, the remote terminal unit is connected with the grouping assembly and disassembly of equipment of CDMA users; the downstream communication method adopts a communication mode of from-modem-to-modem; the upstream communication method adopts an interworking function communication mode. The CDMA gateway and CDMA PAD are additionally arranged between the distribution automation main engine and the remote terminal unit. Network resource occupied by the downstream information is little and a regular polling function of the CDMA PAD can be achieved conveniently. When the upstream information transfers, communication priority and reliability are high; breaking information can be preferentially accepted and processed; emergency can be ensured to be handled at first time; high-speed and effective wireless transmission of the distribution automation can be achieved.

Description

technical field [0001] The invention belongs to the field of distribution automation technology, in particular to a distribution automation communication method based on code division multiple access technology. Background technique [0002] Distribution Automation (DA) is a comprehensive information management system integrating computer technology, data transmission, control technology, modern equipment and management. Reduce operating costs and reduce the labor intensity of operators. DA can enable the power distribution system to realize the following functions: (1) Realize remote monitoring of distribution network status; (2) Realize rapid response and recovery of distribution network faults; (3) Realize distribution network reconfiguration to balance distribution networks (4) Realize the collection and analysis of distribution network big data, and optimize the measurement of power grid operation and maintenance. [0003] like figure 1 As shown, the distribution aut...
