Online cooking fume monitoring system with self-cleaning function and control method

Abstract

The invention discloses an online cooking fume monitoring system with a self-cleaning function and a control method. The system comprises an acquisition controller, a working condition sensor, a cooking fume sensor, a communication module, a display module, a detection module, a cleaning module and a power supply module, wherein the working condition sensor collects working condition data of a fan and a purifier; the cooking fume sensor collects temperature, humidity, and the concentration of particulate matters and VOC in cooking fume; the communication module transmits the cooking fume data to a database; the display module displays the collected data; the detection module comprises a sampling air pump, a probe and a wind speed sensor; a cleaning air pump conveys steam ejected by a steam engine to the probe through the cooking fume sensor; and the acquisition controller is used for fitting and calculating a cooking fume concentration value, receiving a database cleaning control instruction, controlling the working state of the cleaning module, controlling the working states of the fan and the purifier and controlling the sampling air pump to sample and exhaust. According to the online cooking fume monitoring system with the self-cleaning function and the control method provided by the invention, the service life of the sampling air pump can be prolonged, the self-cleaning function is started, and the problem that information interaction is not timely is solved.

Description

technical field [0001] The invention relates to the technical field of oil fume purification, in particular to an online oil fume monitoring system with self-cleaning function and a control method. Background technique [0002] The existing online oil fume monitoring device obtains the oil fume content and the working current of the fan and purifier, performs data processing according to the oil fume content to obtain accurate oil fume data, and judges the working status of the fan and purifier according to the working current of the fan and purifier, and performs Real-time display; on the one hand, the oil fume monitoring data is only displayed on the device screen, and the system cannot be remotely controlled. The function is single and does not support remote interactive information; on the other hand, the oil fume monitoring probe works for a long time, and the probe is easy to block. It is easy to leave oil stains, manual disassembly is time-consuming and laborious, and...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects and deficiencies of the existing technology, the present invention provides an online oil fume monitoring system and control method with self-cleaning function. When the oil fume emission value has been at a high value for a certain period of time, the cleaning module is started through the client The cleaning function can also be used to judge whether the threshold has been reached according to the detected oil fume data, and start the self-cleaning function, which effectively solves the problems of oil fume monitoring probe blockage, easy residual oil stains on the inner wall of the pipeline, and untimely information interaction, further reducing maintenance and operating costs.
