Problems solved by technology
[0003] The traditional method is to use testing equipment such as dry hygrometer, hair hygrometer, humidity test paper and thermometer to carry out manual inspection, and to ventilate, dehumidify and cool down the warehouses that do not meet the temperature and humidity requirements. This manual testing method Time-consuming, labor-intensive, low-efficiency, and the temperature and humidity of the test have large errors and randomness

The invention relates to a local mainframe regulation and control system based on WIFI wireless transmission. The local mainframe regulation and control system comprises a barn, wherein a plurality of air pipes are arranged at the bottom of the barn, the side wall of each air pipe is provided with multiple branch pipes extending into the barn, and the air pipes are connected with a draught fan. A plurality of monitoring rods which are evenly distributed are inserted into the barn, a plurality of temperature sensors which are arranged in the vertical direction are distributed on the monitoring rods, the temperature sensors on the multiple monitoring rods are connected with a control unit in a grouped mode after the monitoring rods are grouped, the control unit is connected with a local mainframe through a WIFI transmission unit, and the local mainframe controls the draught fan through the control unit. According to the local mainframe regulation and control system, the grain temperature change in the barn is remotely monitored by the local mainframe through the WIFI transmission unit, the distance limit of original cable transmission is avoided, and the local mainframe regulation and control system has the advantages of being convenient to operate and reliable in control.
Description
technical field [0001] The invention relates to a granary, in particular to a granary maintenance system. Background technique [0002] Food is the foundation of human survival and development, and food security has always been a major overall strategic issue related to my country's national economic development, social harmony and stability, and national security and self-reliance. In particular, large state-owned granaries store a large amount of grain and require more grain depots. Then there will be problems such as wide distribution of grain depots and long communication distances, and the difficulty of unified management will also increase. To ensure the safe storage of grain is mainly to ensure that it is under normal temperature and humidity. [0003] The traditional method is to use testing equipment such as dry hygrometer, hair hygrometer, humidity test paper and thermometer to carry out manual inspection, and to ventilate, dehumidify and cool down the warehouses ...
