Abstract

The invention discloses a catering lampblack online monitor system based on dual-mode communication. The system comprises a sensor interface circuit, a power supply management circuit, a main controlMCU circuit, a dual-mode communication module M5313 circuit and a liquid crystal display circuit, and the main control MCU circuit is connected with and controls the sensor interface circuit, the power supply management circuit, the dual-mode communication module M5313 circuit and the liquid crystal display circuit. According to the invention, a 2G and NB-IOT self-switching dual-mode communicationtechnology can be realized, the price of the communication module is not increased, the advantages of the 2G network and the NB-IOT network are extracted; the NB-IOT network is preferentially networked, the power consumption of the terminal is effectively reduced, and the high-gain high-penetrability deep coverage capability of the NB-IOT network is utilized to solve the problem that the restaurant to be monitored is automatically switched to 2G network communication in places such as basements where signals are difficult to reach, in urban and rural areas and without NB signals, so as to ensure the reliability of data transmission of the monitored restaurant in various environments.

Description

technical field [0001] The invention relates to the technical field of online cooking fume monitors, in particular to an online cooking fume monitoring system based on dual-mode communication. Background technique [0002] With the improvement of people's living standards, the public's awareness of environmental protection is increasing day by day. Catering oil fumes, as a large source of pollution in the living area, are increasingly harmful to human health and the environment, and related environmental complaints are also increasing day by day. Government departments have enacted laws and regulations that must not exceed the standard for oil fume emissions in the catering industry, and require catering companies to take oil fume purification measures and install oil fume purification devices. However, the reality is that some catering operators often adopt strategies such as not opening and not cleaning, which eventually lead to fume purification equipment being useless. M...
