Measure and control device and method for collecting and storing data

Abstract

The invention provides a measure and control device for collecting and storing data, which is characterized by comprising a central control module, wherein the central control module comprises a communication module and a databank module, the communication module carries out data communication between a main station or a monitoring collector and the databank module, the databank module is used for storing the collected data and carries out data interaction with the communication module, the databank module comprises a real-time databank submodule, a history databank submodule and a calculation amount databank submodule, wherein the real-time databank submodule is used for storing real-time data, the history databank submodule is used for storing history data, and the measure and control device also comprises a data calculation module and a supply and collect module. The invention also provides a method for collecting and storing data. The device and the method complete real-time data collection, data storage and data transmission on one measure and control device, reduces the data loss, and improves the data reliability.

Description

Technical field [0001] The invention relates to the field of measurement and control, and more specifically, to a measurement and control device and method for collecting and storing data. Background technique [0002] In recent years, as the country’s requirements for environmental protection have increased and the transformation of power plants’ desulphurization facilities has been promoted, the National Development and Reform Commission has adopted measures such as adding 1.5 cents per kilowatt-hour of on-grid electricity prices to newly built coal-fired power plants that have installed desulphurization facilities. However, the current operation of desulfurization facilities in coal-fired power plants and the implementation of desulfurization price increase policies still lack effective supervision methods and means. There have been cases in which coal-fired power plants that have installed desulfurization facilities are idle or deliberately not operating desulfurization facili...

AI Technical Summary

Problems solved by technology

[0004] (1). Due to the characteristics of the RTU device, real-time information is collected, and it is impossible to save desulfurization status information for a long time on site. In the event of an abnormal communication channel, automatic supplementary collection of missing information cannot be realized.

[0005] (2). There are great difficulties in the combination of monitoring results and billing electricity. Desulfurization electricity refers to the electricity during the period when the desulfurization efficiency reaches the specified index (established by the Environmental Protection Bureau). The comprehensive electricity price should not only consider the current The time-of-use electricity price that has been implemented should also consider the preferential electricity price for environmental protection (floating electricity price on the basis of the original electricity price). or not) there is great difficulty in accurately auto-combining

By collecting and saving the operation information of the desulfurization system of the power plant, it solves the problem of supplementary mining of missing information when the communication channel is abnormal; calculates the desulfurization efficiency and realizes the monitoring of the desulfurization status on the power plant side; at the same time, it collects power data through the power collector, Accurately complete the statistics of desulfurization operation electricity, and solve the problem that the existing desulfurization information collection system cannot accurately count the desulfurization operation electricity
