Data transmission interface and data transmission method of substation auxiliary subsystem

Abstract

The invention discloses a data transmission interface and a data transmission method of a substation auxiliary subsystem, and belongs to the field of data transmission. Firstly, the equipment type of the auxiliary equipment is determined, and an equipment model of the auxiliary equipment is constructed according to the equipment type; matching a preset equipment model data transmission interface with auxiliary equipment, and distributing an independent ID identification mark to enable each auxiliary equipment to support a transmission interface of the equipment attribute; realizing data transmission of the multi-subsystem equipment model by using an Ethernet bus; acquiring state data and equipment model data of the auxiliary subsystem equipment with the independent ID identification mark, and uploading the state data and the equipment model data to the host through an Ethernet bus; the Ethernet bus has a communication monitoring function, and ensures that auxiliary subsystem equipment is always kept in an online monitorable state. Independent IDs are adopted to identify auxiliary subsystem equipment, all subsystems can operate independently, fusion management of the multiple subsystems is achieved, plug and play of the auxiliary equipment in the transformer substation can be achieved, and instantaneity and reliability of data uploading are improved.

Description

technical field [0001] The invention belongs to the field of data transmission, and in particular relates to a data transmission interface and a data transmission method for an auxiliary subsystem of a substation. Background technique [0002] Due to the large number and wide distribution of the power company's distribution substation machine room, it has the characteristics of being scattered, the geographical environment is changing, the coverage is wide, the users are many, and it is easy to be affected by user capacity expansion and urban construction. In the current situation of limited manpower and material resources for operation and maintenance, the inspection period is lengthened, the inspection efficiency is low, and there are potential safety hazards in inspection. [0003] Compared with the lean monitoring mode of substations, the current environmental monitoring level and monitoring scope of substations are seriously backward, and it is impossible to effectively...

AI Technical Summary

Problems solved by technology

[0006] At present, the improvement of the quality of inspection personnel cannot keep up with the increasingly complex functional structure operation and maintenance requirements of substations. With the construction and development of urban areas, the number of substations is increasing, the distribution is becoming wider and wider, and the equipment inside is becoming more and more complex. , the requirements for the number and skills of inspection personnel are getting higher and higher, which consumes a lot of manpower and material resources, and sometimes it is even impossible to conduct a comprehensive inspection, which leaves a potential safety hazard

[0007] The coexistence of multiple systems not only increases the investment cost, but also greatly increases the maintenance cost in the later period, and the simultaneous operation of multiple manufacturers' equipment will also cause disputes, wasting the owner's time and energy

The way of wiring and networking is not conducive to future equipment replacement and addition

[0008] At present, the access control system of each distribution station uses multiple hardware devices and solutions, which can only be used for local management, which is not conducive to the unified management of outsiders, and there is a great security risk
