Local host temperature control system with guiding direction by temperature-measuring balls with built-in pyroelectric sensors

Abstract

The invention relates to a local host temperature control system with guiding direction by temperature-measuring balls with built-in pyroelectric sensors. The local host temperature control system with guiding direction by the temperature-measuring balls with the built-in pyroelectric sensors comprises a granary. A plurality of air pipes are arranged at the bottom of the granary. The side wall of each air pipe is provided with a plurality of branch pipes leading into the granary. The air pipes are connected with a fan. A fixed side plate is arranged on the side face of the granary. A continuous guide groove is formed in the fixed side plate. A gear driven by a motor is arranged in the guiding groove. The side face of the gear is connected with a monitoring rod extending into the granary. The temperature-measuring balls are arranged on the monitoring rod. The pyroelectric sensors are arranged in the temperature-measuring balls. After the temperature-measuring balls form a group, the pyroelectric sensors form a group and are connected with a control unit. The local host temperature control system with guiding direction by the temperature-measuring balls with the built-in pyroelectric sensors has the advantages that through guiding movement of the motor and the guiding groove, the temperature-measuring balls monitor the temperature of the granary, the detection range is wide, and the detection precision is high; the fan is started by the pyroelectric sensors and a local host to work, control is reliable, and labor intensity is low.

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 ...

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
