Embodiment

[0019] like figure 1 As shown, a kind of boiler deaerator failure warning method based on decision tree system provided by the present invention comprises the following steps:

[0020] Step (1), obtain boiler room environment and boiler operating parameter data A, and then obtain boiler deaerator failure critical value B, according to the mutual learning speed in data A and critical value B Corresponding to the error rate table t, the value in the error rate table t is quantified to a decimal between 0 and 1, and then the deaerator failure error rate table T is established;

[0021] The environmental data of the boiler room include: the size of the boiler room, how many boilers are available, the type of boiler, the time of use, the type of energy supply, etc. Boiler operating parameter data includes furnace temperature, flue temperature, water pressure, steam pressure, water inlet pump flow rate, burner temperature, air duct data, deaerator, etc.

[0022] Step (2): Based o...

Abstract

The invention discloses a boiler deaerator failure early-warning method based on a decision-making tree system, which comprises the following steps: step (1), obtaining boiler room environment and boiler operating parameter data A, then obtaining a boiler deaerator failure critical value B, and establishing a deaerator failure error rate table T; step (2), establishing the decision-making tree system, establishing a contrast system, and logically matching the decision-making tree system with the contrast system; step (3), using an electronic sensor to obtain boiler deaerator data, transmitting the boiler deaerator data to the decision-making tree system, and obtaining a deaerator failure high / low probability P; step (4), if p is larger than 0.8, sending out a warning prompt by a center console; step (5), after receiving the warning prompt sent by the center console, affirming the warning prompt by a boiler worker, and if affirming that a boiler deaerator has a failure, which indicates misjudgement of the decision-making tree system, correcting the decision-making tree system. The method can realize automation judgment on a failure of the boiler deaerator.

Description

technical field [0001] The invention belongs to the technical field of early warning, and in particular relates to a failure early warning method for a boiler deaerator based on a decision tree system. Background technique [0002] At present, all deaerator failure warning systems in China are equipped with electronic sensor prompting systems. The principle of the traditional electronic sensor is to sense the high and low values ​​of the deaerator failure, and to feedback the value of each segment to the central control system in time through the electronic sensor perception. Work through the graphic prompts in the central control system to know the high and low values ​​of boiler deaerator failure. However, due to the high temperature of the boiler tube and the corrosiveness of the boiler water, it has a certain degree of influence on the electronic sensor, which causes a wrong estimate or a false value on the failure feedback value of the deaerator, which causes the boile...
