Cooking fume online monitor for catering industry

Abstract

The invention discloses a cooking fume online monitor for the catering industry, and the monitor is characterized in that the monitor comprises a monitoring host, cooking fume probes, and a working condition sensor; the monitoring host is connected with the cooking fume probes through serial ports or analog interfaces, and the monitoring host is connected with a plurality of cooking fume probes; the working condition sensor is used for detecting the operation states of a fan and a purifier; the monitoring host collects a signal through a switching quantity input interface, and is used for detecting the operation states of the fan and the purifier. The whole structure design employs a modular design, and a wireless communication network is flexibly configured. The monitor fits all types of networks, is provided with a large-size touch liquid screen, and is friendly in man-machine interaction. A user can carry out all installation and configuration without computer and tool, and the monitor brings convenience to the user and a maintainer for the daily use and maintenance, and reduces the use cost.

Description

technical field [0001] The invention relates to an on-line monitor, in particular to an on-line monitor for cooking fumes in the catering industry, and belongs to the technical field of environmental monitoring. Background technique [0002] Food is the most important thing for the people. With the rapid development of the national economy, the material living conditions of ordinary people are getting better and better, and there are more and more catering companies with a wider scope. The pollution of the atmospheric environment by catering companies is becoming more and more serious. . Complaints against catering companies have become the main content of urban environmental complaints. Although most enterprises have certain pollution prevention and control measures, some enterprises do not deal with them in accordance with the requirements in order to save costs. Due to the large number and dispersion of enterprises, it is difficult to meet the requirements of real-time ...

AI Technical Summary

Problems solved by technology

There is only one UART serial port in the standard MiniPCIe interface definition, and the 2G communication module cannot lead out all the integrated two UART serial ports for use, so it is impossible to obtain the signal strength of the wireless communication network while keeping the wireless communication network online. base station information

[0004] In the prior art, the signal transmission line of the oil fume online monitor in the catering industry is generally fixed by screws, and tools must be used for daily maintenance, which is time-consuming and laborious; at the same time, due to the lack of necessary insulation protection, multiple interfaces are prone to false short-circuits, causing signal failures. Abnormal or even equipment damage

The operating voltage of the oil fume probe in the prior art oil fume online monitor for the catering industry is generally DC 5V ~ 12V. For some complex installation points on site, it is often necessary to use long-distance cables for power supply and signal transmission, and DC power supply in the long-term The power supply voltage attenuation on the distance cable is obvious

After long-distance cable transmission, the power supply voltage reaching the oil fume probe does not meet the minimum working voltage requirement, and the installer needs to obtain power supply nearby, which increases the difficulty and cost of installation under such conditions
