On a GIS interface, a cursor is moved to each monitored restaurant, real-time data information of the restaurant can be displayed, and meanwhile, the restaurant with alarm information is highlighted and distinguished for display, so that staff can be prompted conveniently;

the oil smoke concentration detector adopts a special oil smoke sensing technology based on a gas-sensitive component, can comprehensively analyze oil smoke components, thereby obtaining a quantized and accurate oil smoke concentration value, and can simultaneously sense information such as temperature, humidity, pressure and the like of smoke so as to provide reference data for an oil smoke diffusion model and analysis of air pollution degree. Because the oil smoke concentration ranges generated by various different cuisine are different, the oil smoke components are greatly different, in order to effectively measure the oil smoke concentration, a plurality of gas sensors are adopted to carry out cooperative work, the sampling results of the plurality of gas sensors are comprehensively analyzed, and a corresponding mathematical model is established, so that the oil smoke concentration can be accurately calculated. In practical application, the most accurate calculation result can be obtained only by selecting different sensor combinations according to different regional characteristics and aiming at different typical oil fume characteristics, performing different adjustment and configuration on the parameters of the sensors and matching with different analysis methods and mathematical models;

the oil fume is very polluting to the sensor, and the sensor and the related circuits are quickly out of function if unnecessary protection is not carried out. The probe of the oil smoke concentration detector adopts special design and protection technology, the oil dripping nozzle drips oil drops on a smooth conical surface by means of oil drop gravity, the oil drops flow into the collecting pipe automatically through the conical surface, the oil dripping nozzle and the conical surface are manufactured by finding out an angle which does not influence the use function through tests and special materials to reduce the friction coefficient so as to improve the oil drop collecting efficiency, and the sensor can be automatically cleaned, so that the probe can effectively resist oil smoke pollution, the service life of the probe is effectively prolonged, the equipment is simple to maintain, and the maintenance cost is low. The oil fume purifier is customized and developed by cooperation of practical research and test results and foreign professional manufacturers, and relevant parameters are specially designed according to the practical test and research results, so that the optimal effect aiming at various oil fume practical conditions in China can be achieved. Therefore, the service lives of the sensor and the probe can be effectively prolonged;

the probe of the oil smoke concentration detector has a special protection function, and can effectively detect artificial or non-artificial damage to the probe. If the cable between the probe and the collector is pulled out or damaged, the RTU oil smoke monitoring instrument host can automatically identify and alarm; if the probe is moved or dismantled, RTU oil smoke monitoring appearance host computer also can automatic identification and report to the police to effectively prevent equipment from being destroyed or by abnormal use.
