Description
Technical Field
The invention relates to the technical field of electrical equipment, in particular to a method for transmitting on-line monitoring and environment monitoring data of a power distribution ring network cabinet through a DTU (data transfer Unit).
Background
The ring main units are widely applied to urban and rural distribution networks in China, each ring main unit which runs uninterruptedly for a long time generates massive online monitoring and environment data, and how to economically and efficiently transmit massive data of the ring main units which are located on roadside, outside buildings and other complex environments to a power grid enterprise power internet of things platform is a main technical problem to be solved in the technical field of electrical equipment.
The ring main units are distributed at two sides of urban and rural roads, outside buildings and inside and outside industrial and mining enterprises, the environment is complex, the total amount of the ring main units is huge, the communication conditions are uneven, and the large data volume and the high communication cost are caused because the ring main units need to operate uninterruptedly for a long time. In order to save cost, each ring main unit is only provided with one communication outlet, and the communication outlet is used by the DTU of the distribution automation terminal and cannot be shared by other equipment for safety operation and history reasons.
The DTU integrated measurement and control communication unit of the distribution automation terminal is provided with a measurement and control and communication functional module and is responsible for realizing the functions of remote signaling, remote measurement and remote control at intervals without a control unit, the remote signaling and remote measurement information collected by the measurement and control unit is collected through a 104 or 101 protocol, the remote signaling and remote measurement information is uploaded to a distribution automation master station through the 104 protocol according to a forwarding point table, and a remote control command issued by the distribution automation master station is executed or forwarded to a corresponding control unit for execution.
With the development of the technology, the ring main unit also needs online monitoring data which mainly comprises data such as partial discharge online monitoring, temperature online monitoring, mechanical characteristic online monitoring, SF6 gas tank online monitoring and the like; in addition, the ring main unit also needs to be configured with environment monitoring, and mainly monitors entrance guard, water immersion, environment temperature and humidity, smoke sensation and the like.
The online monitoring and environment monitoring data are generally transmitted to the power internet of things platform, and one idea is to develop a device, collect and process the online monitoring and environment monitoring data, and then upload the online monitoring and environment monitoring data to the internet of things platform through an mqtt protocol, which can be called a direct transmission method. The other idea is to modify a distribution automation terminal DTU, to realize various 485/Modbus, tcp/Modbus and proprietary protocols required to be used, to collect data from online monitoring and environmental monitoring data via the protocols, and to send the data to a distribution automation master station system together with other telemetering and remote signaling data, which is called an indirect transmission method.
The main disadvantage of the direct transmission method is that a network communication channel 2 needs to be established in addition to the network communication channel 1 used by the distribution automation terminal DTU, which is costly and often even unconditional.
The indirect transmission method can multiplex the network communication channel 1, and on-line monitoring and environment monitoring data are transmitted through the DTU, so that the communication cost is saved. However, the indirect transmission method needs to modify a distribution automation terminal DTU, so that various 485/Modbus, tcp/Modbus and proprietary protocols used are realized, online monitoring and environment monitoring data are acquired through the protocols, the modification is not feasible, the cost is increased, the reliability is reduced, and particularly for in-transit equipment.
