Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] The present invention is used for the sensor self-inspection method of industrial furnaces and boilers, which is different from the prior art in which the detection values ​​between sensors of the same type are used to verify each other, and is also different from the prior art in which paired sensors are set at the same detection point , but start from the whole sensor system to build a data relationship network. The data of different detection points are related to the operation status of the entire boiler and irrelevant, and there are data correlations and non-correlations between different detection points. The method of the present invention models the above-mentioned relationship network from the aspect of data relevance in a direction different from the conventional thinking, and mainly divides into the following four types of mathematical ...

Abstract

The invention relates to a sensor self-inspection method for industrial furnaces and boilers, which includes modeling and self-inspection. The modeling starts from the entire sensor system and builds a relational network on the data. The data of different detection points are related to the entire sensor system. Boiler operating status is related and irrelevant, there is data correlation and non-correlation between different detection points, and four types of mathematical models are established; the self-inspection includes: the detection value actually detected by the sensor that needs self-inspection The detection theoretical values ​​in at least one of the four types of mathematical models are compared in real time, and if the difference between the two exceeds a tolerance range, it is judged that the sensor has drifted or is damaged. The invention also relates to a sensor self-inspection system for industrial furnaces and boilers. The invention does not need to configure multiple sensors of the same type, and solves the problems of high equipment cost and restrictions on on-site installation and arrangement caused by the prior method of comparing and self-inspecting multiple sensors of the same type.

Description

technical field [0001] The invention relates to industrial furnaces and boilers, in particular to a sensor self-inspection method and system for industrial furnaces and boilers. Background technique [0002] my country's industrial furnaces and industrial boilers are typical high-energy-consuming, high-emission, and high-pollution equipment. Equipment can be provided. With the intensification of industry competition and the country's increasingly stringent energy conservation and environmental protection requirements, in order to improve the operational energy efficiency of industrial kilns and industrial boilers, it has better controllability in terms of combustion efficiency, operational safety, energy conservation and environmental protection, etc. The rapid development of Internet of things technology and artificial intelligence technology in industrial furnace and boiler industry. As the basis for supporting the Internet of Things and artificial intelligence technology...
