Description

Technical Field

[0001] This invention relates to the field of power distribution environment monitoring technology, specifically to an intelligent power distribution environment monitoring sampling device. Background Technology

[0002] Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the load is concentrated and there are more circuits. Many factors need to be monitored in the distribution cabinet room.

[0003] Traditional monitoring devices use independent sensor units, resulting in severe data silos. They can only monitor temperature at a single point and cannot construct a three-dimensional temperature field inside the cabinet. Switch mechanical condition diagnosis relies on regular manual maintenance, requiring disassembly of the switch to measure contact wear. Fire early warning response is delayed, and smoke sensors require a smoke concentration of 65dB / m³ to trigger an alarm. Partial discharge detection requires an external high-frequency CT. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent power distribution environment monitoring and sampling device to solve the problems mentioned in the background art.

[0005] A smart power distribution environment monitoring and sampling device, comprising:

[0006] The sampling and monitoring unit is used to collect various parameter signals of the power distribution environment in real time.

[0021] Preferably, the server has a built-in data recording module.

[0022] Preferably, the server's communication protocols support Modbus RTU / TCP, IEC 61850MMS, and SNMPv3.

[0023] The beneficial effects of this invention are as follows: This invention achieves real-time and collaborative acquisition of key parameters of the power distribution environment through a highly integrated sampling and monitoring unit, completely breaking down the data silos formed by traditional independent sensors. The server's built-in edge computing module performs on-site real-time cleaning, fusion, and in-depth analysis of multi-source heterogeneous data. Combined with a multi-level early warning mechanism, it significantly improves the system's intelligence level, enabling the construction of a three-dimensional temperature field in the computer room for precise temperature control. It also allows for online diagnosis of switch mechanical status without relying on manual disassembly and maintenance, greatly improving the fire early warning response speed. It breaks through the traditional 65dB / m concentration limit of smoke sensors to achieve early alarms and can directly support high-frequency CT access to achieve partial discharge detection without additional peripherals. At the same time, the server's powerful data recording module ensures the complete storage and traceability of historical data, and it is widely compatible with Modbus RTU / TCP, IEC61850MMS, and SNMP.

Ultimately, all processing results, early warning information, and historical records are presented intuitively and visually through the display platform, providing maintenance personnel with a comprehensive and dynamic view of the environment and equipment status, as well as precise decision support. This effectively prevents faults, shortens fault response time to the second level, significantly reduces maintenance costs, and comprehensively improves the reliability, safety, and intelligent management level of the power distribution system.
