Intelligent identification method and system of flame sensor

Abstract

The invention provides an intelligent identification method and system of a flame sensor. An operation mode and a learning mode are provided. The information processing process of the operation mode comprises the steps of: Y1, receiving external signals; Y2, converting analog signals received in the step Y1 into digital signals; Y3, calculating a practical output result according to the digital signals and weight values; and Y4, determining whether to carry out alarming according to the practical output result. The information processing process of the learning mode comprises the steps of: X1, executing the steps Y1, Y2 and Y3; X2, receiving an expected output result which is input externally; X3, comparing the practical output value with the expected output result; X4, updating the weight values according to the comparison result; and X5, storing the updated weight values for the usage in the step Y3 of the next time. According to the invention, debugging is further carried out after the installation of equipment is completed, the flame sensor is enabled to carry out machine learning repeatedly in the working environment under the learning mode, the flame distinguishing capability is continuously improved, and the alarming accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular, to an intelligent identification method and system of a flame sensor with self-optimization function. Background technique [0002] A flame sensor is a fire detector used to respond to the light characteristics of a fire, that is, to detect the light intensity of the flame burning and the flickering frequency of the flame. For example, the commonly used infrared flame sensor now uses the characteristics of infrared light to be very sensitive to the flame, uses a special infrared receiver tube to detect the flame, and then converts the brightness of the flame into a level signal with high and low changes, which is input to the central processing unit. The processor makes corresponding program processing according to the change of the signal. With the development of economy and the construction and use of a large number of buildings, the automatic fire alarm system fo...

Problems solved by technology

However, due to the difference between the test environment of the flame sensor before leaving the factory and the real installation environment, false alarms or missed alarms are likely to occur during the use of the flame sensor, which makes the firefighters on duty troubled and even more serious. may even threaten the safety of people's lives and property
