Problems solved by technology

The communication protocols such as IEC60870-5-104 and IEC60870-5-101 currently used in the distribution automation system only solve the problem of data transmission. The data transmission between the main stations of distribution automation requires manual association of data point tables, which cannot realize plug-and-play distribution terminals, resulting in a very heavy workload for distribution automation construction and maintenance

Abstract

The invention relates to a CoAP protocol-based plug-and-play networking method for a side end of a power distribution internet of things. The CoAP protocol-based plug-and-play networking method comprises the following steps of: 1, modeling a process layer and a spacer layer of an ad hoc network system; 2, newly adding a logic device, wherein the device undertakes the responsibility of fault processing; 3, establishing an expanded power distribution terminal information model; 4, mapping the data model of the IEC61850 standard to an IEC60870-5-104 data model of the IEC61850 standard; 5, establishing models of a distribution network switching station, a ring main unit, a branch box and a distribution network switch; 6, initializing a power distribution terminal; 7, enabling the power distribution main station to acquire measurement and control information, protection information and power supply information of the power distribution terminal; and 8, after receiving the self-description file, enabling the power distribution main station system to convert the self-description file into a configuration file which can be identified by a main station system tool. According to the invention, the power distribution terminal has a self-description capability, so that plug and play is realized.

Description

technical field [0001] The invention belongs to the field of on-site rapid networking methods for power distribution Internet of Things equipment, and relates to a side-end plug-and-play networking method for power distribution Internet of Things, especially a CoAP protocol-based side-end plug-and-play networking for power distribution Internet of Things method. Background technique [0002] The power distribution network is directly connected to users, which has the most direct impact on customers, and the customer's service experience is also the strongest. On the other hand, the voltage level of the distribution network is low, the construction period is short, and the scope of influence of a single device is small, which is more suitable for Pilot and rapid promotion of new technologies and equipment. Therefore, the distribution network is an extremely critical and fast-acting important component in the construction of the ubiquitous power Internet of Things. The produ...
