Problems solved by technology

[0002] Existing temperature inspection systems are based on independent systems. Since the system does not use compression, the amount of sampled data is large, and the historical data saved is limited by the capacity of the hard disk. It is impossible to save historical data for a longer period of time. It is very inconvenient to manually record the temperature change account of the equipment

Embodiment Construction

[0014] Such as figure 1 and figure 2 Shown, based on the temperature ledger control method of PI real-time database, it is characterized in that: comprise the following steps:

[0015] Step 1: Collect temperature data through the temperature data acquisition module, and then proofread and format the data;

[0016] Step 2: Save the temperature data obtained in Step 1 to the PI database processing module after being compressed by a revolving door and filtered twice;

[0017] Step 3: Extract the temperature data in the PI database processing module through the data operation analysis module, and provide the man-machine interface in the form of temperature ledger.

[0018] 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 tem...

Abstract

The invention provides a control method for temperature record based on a PI real-time database, which comprises the steps of: 1) collecting temperature data by a temperature data collecting module and calibrating the data and converting the format of the data, 2) compressing the temperature data acquired in the step one by a rotating door, secondarily filtering and then storing in a PI database processing module, and 3) extracting the temperature data in the PI database processing module by a data running analysis module so as to provide a human-computer interface in the manner of temperature record. By using the method of the invention, the hard disk space is greatly saved, the operation of manually recording the device temperature change record is not required, and the use is convenient.

Description

technical field [0001] The invention relates to a temperature account control method based on a PI real-time database. Background technique [0002] Existing temperature inspection systems are based on independent systems. Since the system does not use compression, the amount of sampled data is large, and the historical data saved is limited by the capacity of the hard disk. It is impossible to save historical data for a longer period of time. It is very inconvenient to manually record the temperature change account of the equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a temperature account control method based on PI real-time database, which can greatly save hard disk space, does not need to manually record the temperature change account of equipment, and is easy to use. [0004] For solving above-mentioned existing technical problem, the present invention adopts following scheme: the temperature ac...
