In order to realize the dynamic supervision of catering lampblack and promote the sustainable development of the city?s catering enterprises and various social undertakings, deploy the intelligent supervision system and realize the monitoring platform to urge catering enterprises to consciously use and clean and maintain lampblack purification facilities, so as to achieve the effect of lampblack emission. Platform system will be not open for catering enterprises lampblack purification facilities or lampblack emissions, or no regular cleaning maintenance of all kinds of irregular behavior, immediately prompt warning, remind restaurant owners, and send the data to the relevant management personnel, from the source strictly control food lampblack emissions, put an end to lampblack pollution, improve the ability of urban environment comprehensive monitoring.
system design
The construction of the project fully use the mobile Internet, Internet of things, big data, cloud computing wisdom, information means, on the basis of the existing, through system integration, resource integration, information sharing, establish scientific, efficient, unified food lampblack information supervision system, the system set data collection, signal transmission, background data processing, terminal data display function into an organic whole, by the data processing system, lampblack monitoring system and mobile client. Realize real-time data monitoring. Accurately provide continuous automatic monitoring of the catering industry lampblack emissions, and upload to the server background program for statistical analysis.lampblack monitoring mainly includes three parameters: lampblack concentration, particulate matter and non-methane total hydrocarbon, which are uploaded to the data center and monitoring platform in real time. Collect and store various kinds of monitoring data, and send monitoring data and equipment working status to the background server according to the instructions of the background server. Identify, check and store the collected monitoring data; process the collected monitoring data according to the statistical requirements; set the lampblack concentration threshold, and automatically start the lampblack purification facility after the threshold. The staff in the platform terminal or mobile terminal to supervise whether the catering enterprises open the lampblack treatment facilities or whether the lampblack emission exceeds the standard, and whether there are all kinds of non-standard behaviors without regular cleaning and maintenance.
Hardware composition of the online monitoring system of lampblack concentration
In order to truly and effectively monitor the lampblack emission of the catering industry, our company uses OEN-100 lampblack online monitor for real-time sampling and analysis of the lampblack, so as to get the accurate quantitative data of the lampblack concentration, so as to truly bring the lampblack emission of the catering industry into the online monitoring system of pollution sources.
OEM-100 lampblack data collector integrates GPRS wireless communication module (optional CDMA) for real-time online and automatic reporting. The collector has a special interface for the lampblack probe to connect the probe. The collector controls the original data of the lampblack by collecting the probe, reads the original data collected by the probe, and makes comprehensive calculation, and finally obtains the lampblack concentration value.
Due to the complex composition of lampblack, the lampblack probe of OEN-100 adopts special technology, which can conduct comprehensive analysis of a variety of lampblack components, so as to get the most accurate data of lampblack emission data.
In view of the actual situation of the lampblack emission in the catering industry and the actual situation of the flue, as well as the requirements of real-time sampling, we designed the probe to install convenient, stable and reliable. Because the lampblack is easy to pollute the sensor, so the OSEN-100 probe adopts a special design, can effectively filter the large diameter particle dust, making the probe can effectively resist the lampblack pollution, prolong the service life of the probe, the maintenance of the equipment is simple, the maintenance cost is low.

In our study, we found that the lampblack is highly polluting to the sensor, and without the necessary protection, the sensor and related circuits will soon lose their effect. The probe of the lampblack concentration detector adopts special design and protection technology, which can automatically clean the sensor, so that the probe can effectively resist the lampblack pollution, so as to effectively extend the service life of the probe, making the maintenance of the equipment simple and the maintenance cost is low. The protection technology includes the use of a special protective filter material, which is also customized according to the actual research and test results in cooperation with foreign professional manufacturers. The relevant parameters are specially designed according to the actual test and research results, which can achieve the best effect for the actual situation of various domestic lampblack. This can effectively extend the service life of the sensor and the probe.
(2) Probe protection
The probe of the lampblack concentration detector has a special protection function, with good protection and maintenance-free ability. If the cable between the probe and the collector is removed or damaged, the lampblack monitor will automatically identify and alarm; thus effectively preventing the equipment from being damaged or being in abnormal use.
