Through the adjustment of the valve core, the gas flow rate can be accurately controlled and adjusted. Its control logic is to automatically adjust the opening and closing area of the valve according to the change of air volume and flow rate, so as to achieve accurate control of the air flow. In addition, the control logic of the Venturi valve also involves displacement sensors to measure the opening of the exhaust cabinet sliding door in real time, and also involves variable air volume controllers, which realize the adjustment and control of the variable air volume Venturi valve as an "actuator" through calculation to ensure the required exhaust volume value. Venturi valves are widely used and important in the food processing industry. From raw material processing to processing, to packaging and storage stages, they play an indispensable role. They can control the inlet and outlet air volume of the food processing site in real time according to production and processing needs. However, the existing control technology has the problems of single monitoring parameters, slow response speed and insufficient adjustment accuracy, which makes it difficult to meet the needs of high-precision and multi-parameter control. Summary of the invention

When the air volume change intensity difference in the food processing place exceeds the preset air volume change intensity difference, the system determines that the air volume change in the food processing place is in an abnormal state and issues an early warning. Otherwise, no determination is made.
[0046] The acquisition module 1303 is used to acquire the intensity difference data of different air volume changes calculated by the calculation module 1302, and to acquire the intensity difference data that appears most frequently in the food processing site, and to analyze the correlation between the intensity difference data and the changes in the environmental data information outside the food processing site;
[0047] The monitoring terminal 140 is used to record the control and adjustment party that matches the Venturi valve control system of the preset monitored food processing site, receive the field data uploaded by the collection monitoring point, and update the background data at the same time. When the air volume change intensity difference in the monitored food processing site exceeds the preset air volume change intensity difference, a request for obtaining information on the Venturi valve air volume change is initiated to the control and adjustment party that matches the Venturi valve control system of the preset monitored food processing site.
