Description

Defect data marking method and system based on garbage incineration power generation
Technical Field
The invention belongs to the technical fields of environmental engineering and garbage disposal, and particularly relates to a defect data marking method and system based on garbage incineration power generation.
Background
The method for counting the generated energy of the garbage incineration adopted by the garbage incineration power plant at the present stage comprises a kilowatt-hour meter, a smart grid technology, an SCADA system or a remote monitoring system and the like, wherein the smart kilowatt-hour meter is widely used due to high precision and high stability, and can provide the functions of remote reading and real-time data monitoring so as to facilitate the garbage incineration power plant to perform more efficient energy management; however, in the process of counting the generated energy in real time, garbage in the incinerator can generate explosive combustion events due to accumulation of inflammable gas, pressure accumulation, chemical reaction or dust explosion, although garbage pretreatment and combustion control can prevent middle-high-intensity explosive combustion events, the occurrence of middle-low-intensity explosive events in the garbage incineration process cannot be stopped, the occurrence of explosive events can cause the increase of heat energy, the acceleration of combustion speed and the rapid increase of heat release rate of the garbage incineration, and the generated energy or the combustion degree generated by the garbage incineration power generation device can also be instantaneously and rapidly increased due to the sudden increase of heat energy. The process of the explosive combustion event is short, the risk brought by the process of monitoring the total amount of generated energy of the garbage incineration power generation device is small, but the accuracy of real-time measurement of the kilowatt-hour meter is greatly deviated, the process of real-time adjustment of the garbage feeding amount in the garbage incineration process is challenged, the analysis effect of a big data model is also caused to slide down due to the deviation of the real-time monitoring data when the big data is applied, and finally the stability of a combustion control system of the garbage incineration power generation plant is damaged, so that a method for marking the explosive combustion event in garbage incineration power generation is needed to solve the technical problem.

and S400, marking the explosive combustion event according to the explosive effect state and storing the explosive combustion event in a server.
Further, in step S100, the method for arranging the explosive combustion marking scene in the garbage incineration power plant is as follows: an explosion combustion marking scene is arranged in a garbage incineration power plant and comprises a garbage incinerator, a plurality of node groups formed by temperature sensors and pressure sensors are uniformly distributed on the furnace wall of the garbage incinerator, the temperature sensors and the pressure sensors are high-temperature-resistant sensors, the temperature sensors are thermocouple temperature sensors, platinum resistance temperature sensors or infrared temperature sensors, and the pressure sensors are strain gauge type pressure sensors, ceramic pressure sensors or capacitive pressure sensors.
Further, in step S200, the method for acquiring the temperature value and the pressure value from the explosive combustion marking scene to form the load array is as follows: setting a time period as a detonation monitoring interval EFDD, wherein EFDD epsilon [5, 30] minutes, in the latest EFDD time period, the node groups in the garbage incinerator all obtain continuous temperature values and pressure values, and the temperature values and the pressure values obtained by the node groups in the garbage incinerator at one moment are recorded as a load array of the node groups at the moment.
Further, in step S300, the method for obtaining the deflagration performance states at each moment by using the load array calculation is as follows: setting a time period as an explosion monitoring interval EFDD, setting the value range of the time period as EFDD epsilon [5, 30] minutes, constructing a load array at each time point in the explosion monitoring interval into a sequence and recording the sequence as a load array sequence ALS, wherein each element in the load array sequence is a binary group comprising a temperature value and a pressure value;
