Problems solved by technology

[0002] The existing temperature inspection system is based on its own independent system and cannot be interconnected with other systems, so the temperature data of the substation can only be limited to the substation, and the temperature of the equipment in the substation can only be known through the on-site inspection of the operating personnel
Due to the limitation of system hardware conditions (hard disk capacity, processing speed, etc.), the existing temperature inspection system can only reflect the temperature changes of the equipment in real time, and cannot save long-term historical data, so it cannot be comprehensive when analyzing data Analysis, it is not easy to accurately judge the operation of the equipment
The existing temperature inspection system only reflects the condition of the equipment through the change of a certain temperature measuring point, and does not provide the analysis means of horizontal comparison and vertical comparison for comprehensive analysis

Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, the temperature inspection control method based on PI real-time database comprises the following steps:

[0016] Step 1: Collect temperature data through the temperature inspection acquisition module, and then proofread and format the data;

[0017] Step 2: save the temperature data obtained in step 1 into the PI database processing module;

[0018] Step 3: Extract the temperature data in the PI database processing module through the data operation analysis module,

[0019] and analyze.

[0020] In the first step, the current temperature of each operating equipment in the substation is collected into the temperature inspection acquisition module through the RS485 bus, and the data is checked by the CRC16 verification method, and then the format of the collected temperature data is converted. The temperature patrol acquisition module connects the temperature data to the PI database processing module through the PI database in...

Abstract

The invention relates to a temperature polling control method based on a PI (proportional-integral) real-time database, comprising the following steps: step I: temperature data are acquired by a temperature polling acquisition module, and proofreading and format conversion are carried out on the data; step II: the temperature data obtained in the step I are stored in a PI database processing module; and step III: the temperature data in the PI database processing module are extracted by a data running analysis module for analysis. Historic storage of the temperature data can be realized, the current running condition of transformer substation equipment can be accurately reflected, the working personnel can know the temperature change of the transformer substation equipment without going to the spot, and the scientific and reasonable decision can be made.
