[0002] A scraper, also known as a scraper, is a mechanical device used to clean and remove slag, dirt or solid impurities on the surface of industrial equipment. It is commonly used in industrial production processes, especially in industries such as oil refining, chemicals, steel, and electricity. The main function of a scraper is to clean the residue and dirt on the surface of the equipment to ensure the normal operation and production efficiency of the equipment. In the industrial process, some substances will accumulate on the surface of the equipment, such as sediment, coke slag, solid residue, etc. If they are not cleaned in time, it will affect the heat conduction, fluid flow, and material quality of the equipment. The scraper uses tools such as scrapers or brushes to effectively scrape or clean these impurities to keep the equipment clean and running smoothly.
[0003] The intelligent control system of the scraper is based on the development of modern industrial automation and information technology. It integrates a variety of advanced technologies and aims to improve the working efficiency, reliability and intelligence of the scraper.

If the fault cannot be detected or the false alarm cannot be eliminated in time, it will lead to extended downtime, production line interruption, equipment damage, or maintenance personnel delaying unnecessary maintenance work, affecting normal work and production. Therefore, it is necessary to provide an intelligent control system for the scraper to solve the above technical problems. Summary of the invention

[0045] The time required for the scraper to complete a working cycle is recorded as the working speed DG, wherein the working cycle includes the movement of the scraper knife, the removal and transportation of materials and other operating steps. The working cycle is set by combining the specific type and model of the scraper, and it is a prior art operation, so it will not be described here.
[0046] Obtain the volume DF1 of the material cleaned by the scraper in one working cycle, and weigh the cleaned material when conveying it to obtain its weight DF2; calculate the volume and weight of the material cleaned by the scraper several times, and use the formula To obtain the cleaning value DF of the cleaning object;
[0047] The working speed, moving speed and cleaning value of the scraper are weighted and calculated, and the formula DS=DG×a1+DH×a2+DF×a3 is used to obtain the ergonomic value DS of the scraper; wherein a1, a2, and a3 represent the weight factors corresponding to the working speed, moving speed and cleaning value of the scraper, respectively; by evaluating and analyzing the working efficiency of the scraper, the working speed, moving speed and cleaning value of the scraper are obtained, and weighted calculation is performed according to the weight factors to obtain the ergonomic value of the scraper, which assists management personnel in understanding the working efficiency of the scraper, thereby evaluating the working performance and production capacity of the equipment;
[0048] Perform fault analysis on the motor operation information of the scraper, obtain the motor operation information on the scraper, set the preset time zone, select the motor operation information of the motor in the preset time zone for statistical index processing, so as to obtain the average value, median and standard deviation corresponding to the motor parameters; perform weighted calculation on the average value FG1, median FG2 and standard deviation FG3 corresponding to the corresponding parameters of the motor, and use the formula Obtain the operation value FG of the corresponding motor; wherein the statistical indicator processing includes the calculation processing of the mean value, the median, and the standard deviation; the parameters in the motor operation information include the current, voltage, temperature, vibration, decibel, and load of the motor; the parameters in the motor operation information are numbered as m, and their set is represented as M; mδ represents the weight influencing factor on the motor when the parameter in the motor operation information is m; set a set normal threshold value for the motor operation value, compare the operation value with the set normal threshold value, if the operation value is not within the set normal threshold value, generate a motor abnormal signaling, if the operation value is within the set normal threshold value, generate a motor normal signaling; mark the motor normal signaling and the motor abnormal signaling as a motor detection signal group;
[0049] After the motor stops abnormally, the abnormal signal of the motor is verified and analyzed, and the motor protection device is tested. If any of the protection devices in the motor protection device is triggered, a motor damage signal is generated; the motor protection device is overload protection, overheat protection, and short circuit protection; if none of the motor protection devices are triggered, a heat dissipation analysis is performed on the temperature information of the corresponding motor, and the shell temperature, rotor temperature and motor ambient temperature at multiple positions corresponding to the current moment are extracted, and the average value is calculated to obtain the shell temperature value, rotor temperature value and ambient temperature value, and the shell temperature value, rotor temperature value and ambient temperature value are weighted to obtain the motor temperature shadow value; the motor temperature shadow value is compared with the motor temperature shadow value.

If the motor abnormal signaling is generated again, the motor damage signaling is generated. If the corresponding number of fault analysis and processing all generate the motor normal signaling, the motor actual normal signaling is generated; the motor actual normal signaling and the motor damage signaling are marked as the motor actual condition signaling group;

[0052] It should be noted that by performing fault analysis on the motor operation information, verification analysis will be performed on the motor that stops abnormally, and further analysis will be performed on the motor protection device and temperature information, which will help eliminate false alarms and confirm whether the motor is actually faulty, and provide accurate information and guidance for maintenance personnel; and when it is determined that the motor is faulty, priority determination analysis will be performed to determine the maintenance priority. For example, when the scraper equipment is moving, if any of the motors, such as the stripper motor, bucket motor, and conveyor belt motor, is damaged, a secondary priority will be generated, and if the crawler motor is damaged, a primary priority will be generated; by means of priority determination and maintenance scheduling, maintenance work can be reasonably arranged to improve maintenance efficiency and equipment availability;
