Problems solved by technology

[0004] In the above-mentioned prior art, if the amount of collected data is relatively large, the more devices that need to transmit data, the greater the pressure on the network, the I / O pressure of data processing will cause abnormalities in the collection industrial computer, and the consumption of a large number of hardware resources will make the The industrial computer crashes, and the fixed-frequency acquisition cannot reasonably allocate resources for equipment or measurement points

Abstract

The invention discloses a power station equipment data acquisition method and system. The method comprises the following steps: creating at least one SQLite thread according to equipment information;storing the configuration information of the equipment and the measurement points into an SQLite database; querying equipment information in the SQLite, and classifying the equipment information according to the IP and port information, wherein each type creates a thread; acquiring measurement point configuration information in a single thread according to details of each device; acquiring measurement point data, comparing the acquired measurement point data with a Redis database, and selecting whether to store the measurement point data and report the measurement point data according to a comparison result. According to the method and the system, the timeliness of data transmission of the power station equipment can be effectively improved, the total amount of data transmission can be reduced by collecting the equipment measuring point data in a grading manner, and the network pressure during data transmission is reduced.

Description

[0001] field of invention [0002] The invention relates to the field of data collection, in particular to a data collection method and system for power station equipment. Background technique [0003] The existing technical solution mainly collects the power station equipment list through the SQLite database, classifies according to the IP address and port of the equipment list, and establishes measuring points for the classified equipment to measure the status of each equipment. The measurement point data needs to be uploaded to the host computer, mainly through the modbus protocol, and the measurement point data summarized by the device is reported through the kafka cluster. [0004] In the above-mentioned prior art, if the amount of collected data is relatively large, the more devices that need to transmit data, the greater the pressure on the network, the I / O pressure of data processing will cause abnormalities in the collection industrial computer, and the consumption of...
