Embodiment
[0019] like figure 1 As shown, a kind of boiler circulating pump fault early 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 circulation pump 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 0-1, and then the circulating pump 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 include: furnace temperature, smoke temperature, water pressure, steam pressure, water inlet pump flow, burner temperature, air duct data, circulation pump, etc.

The invention discloses a decision tree system based early warning method for faults of a boiler circulating pump. The decision tree system based early warning method comprises the following steps: step (1), obtaining boiler room environment and boiler operation parameter data A, obtaining a critical fault magnitude B of the boiler circulating pump, and establishing a fault error rate table T of the circulating pump; step (2), establishing a decision tree system and a contradistinction system, and performing logic matching on the decision tree system and the contradistinction system; step (3), obtaining real-time data of the boiler circulating pump by an electronic sensor, and transmitting the real-time data to the decision tree system, thereby obtaining fault high-low value probability P of the circulating pump; step (4), if P is greater than 0.8, giving alarm by a central console; and step (5), confirming after a boiler worker obtains alarm given by the central console, indicating that the decision tree system judges wrongly if the boiler circulating pump is confirmed to have faults, and correcting the decision tree system. The decision tree system realizes automatic judgment for faults of the boiler circulating pump.
Description
technical field [0001] The invention belongs to the technical field of early warning, in particular to a boiler circulating pump failure early warning method based on a decision tree system. Background technique [0002] At present, the electronic sensor prompting system is set up in all domestic circulating pump fault warning systems. The principle of the traditional electronic sensor is to sense the high and low values of the circulating pump fault, and to feedback the value of each segment to the central control system in time through the electronic sensor perception. The work can know the high and low values of the boiler circulating pump failure through the graphic and text prompts of the central control system. 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 fault feedback value of the circulating p...
