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.
Description
Technical field
The present invention relates to temperature patrol inspection control method based on the PI real-time data base.
Background technology
Existing temperature patrol inspection system all is based on independently system itself, can not realize interconnected with other system, so the temperature data of transformer station can only be confined in this transformer station, can only be by the on-the-spot temperature conditions that could understand this substation equipment of making an inspection tour of operations staff.Be subjected to the limitation (hard-disk capacity of system hardware condition, reasons such as processing speed), existing temperature patrol inspection system can only reflect the temperature variation of equipment in real time, can't preserve long historical data, so in data analysis, can not accomplish analysis-by-synthesis, also with regard to the ruuning situation of bad accurate judgment device.Existing temperature patrol inspection system only reflects the equipment situation by the variation of a certain temperature point, does not provide the analysis means of lateral comparison and longitudinal comparison to come analysis-by-synthesis.
Summary of the invention
Technical matters to be solved by this invention is to provide the temperature patrol inspection control method based on the PI real-time data base, can realize the history preservation of temperature data, accurately reflect the current ruuning situation of substation equipment, the staff needn't arrive the on-the-spot device temperature that just can understand transformer station and change, and makes scientific and reasonable decision-making.
For solving above-mentioned existing technical matters, the present invention adopts following scheme: the temperature patrol inspection control method based on the PI real-time data base is characterized in that: may further comprise the steps:
Step 1:, then data are proofreaded and format conversion by temperature patrol inspection acquisition module collecting temperature data;
Step 2: the temperature data that obtains in the step 1 is saved in the PI database processing module;
Step 3:, and analyze by the temperature data in the data run analysis module extraction PI database processing module.
As preferably, be to collect in the temperature patrol inspection acquisition module in the described step 1, and adopt the verification mode of CRC16 that data are proofreaded by the Current Temperatures of RS485 bus with each operational outfit of transformer station, then the temperature data of gathering is carried out format conversion.
As preferably, described temperature patrol inspection acquisition module is linked into temperature data in the PI database processing module by PI database interface software, and PI database processing module is saved in corresponding data cell with the temperature data that inserts.
As preferably, described data run analysis module comes out the data extract in the PI database processing module, adopts the method for lateral comparison and longitudinal comparison to carry out data analysis, points out corresponding alert event when temperature reaches threshold value.
Beneficial effect:
The present invention adopts technique scheme that temperature patrol inspection control method based on the PI real-time data base is provided, realized the history preservation of temperature data, accurately reflected the ruuning situation that substation equipment is current, the staff needn't arrive the on-the-spot device temperature that just can understand transformer station and change, and makes scientific and reasonable decision-making.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a data flowchart of the present invention.
Embodiment
As depicted in figs. 1 and 2, the temperature patrol inspection control method based on the PI real-time data base may further comprise the steps:
Step 1:, then data are proofreaded and format conversion by temperature patrol inspection acquisition module collecting temperature data;
Step 2: the temperature data that obtains in the step 1 is saved in the PI database processing module;
Step 3: by the temperature data in the data run analysis module extraction PI database processing module,
And analyze.
Be to collect in the temperature patrol inspection acquisition module in the described step 1, and adopt the verification mode of CRC16 that data are proofreaded, then the temperature data of gathering is carried out format conversion by the Current Temperatures of RS485 bus with each operational outfit of transformer station.Described temperature patrol inspection acquisition module is linked into temperature data in the PI database processing module by PI database interface software, and PI database processing module is saved in corresponding data cell with the temperature data that inserts.Described data run analysis module comes out the data extract in the PI database processing module, adopts the method for lateral comparison and longitudinal comparison to carry out data analysis, points out corresponding alert event when temperature reaches threshold value.Lateral comparison refers to that A, the B of co-located, C three compare, when the alarm of the temperature anomaly Times temperature difference (example: A is 40 degree mutually, and B is 40 degree mutually, and C is 60 degree mutually, illustrate that C is mutually unusual, and the newspaper three-phase temperature difference is reported to the police, and also are that 40 degree explanation three-phase equilibrium operations are normal mutually as C).Longitudinal comparison refers to same point for measuring temperature Current Temperatures, and relatively (the mutually current temperature 60 of example: A is spent when temperature variation surpasses temperature rise threshold value Times intensification alarm with historical temperature, historical temperature is 40 degree, threshold value is 15 degree, and temperature rise changes above 15 degree newspaper temperature rise alarms).
The PI system is integrated, the application platform of factory's real time data based on C/S and B/S structure by the exploitation of OSIsoft company.The PI system is with all production datas of the long-term online storage factory of the mode of data original shape, and the satisfied requirement of carrying out data acquisition, storage and demonstration fast and efficiently.The present invention is based on the WINDOWSXP/2000 system.With the temperature patrol inspection data at transformer station scene the long-range access local side of mode and interface software PI real-time data base, realize that the related personnel needn't arrive the on-the-spot device temperature variation that just can understand transformer station by Ethernet.Realize the history preservation of temperature data by PI real-time data base active data management function.The science comparative approach of employing lateral comparison and longitudinal comparison has possessed the ability of analysis-by-synthesis, can reflect the ruuning situation that substation equipment is current accurately, is convenient to relevant functional department and makes scientific and reasonable decision-making.
