Technical Field

The invention relates to a granary measuring and controlling machine, and belongs to the technical field of sensor detection.

Background

Agriculture is the foundation of national economy, and grain is the foundation of the foundation. In recent years, with the continuous progress of agricultural science and technology, the agricultural production is continuously and stably increased in yield, the amount of grains produced by farmers is increased day by day, and most farmers not only solve the problem of satiety, but also have more grains. The annual grain yield and annual storage capacity are at the top of the world. The central grain storage has relatively perfect storage facilities and technical guarantee, and plays an important role in guaranteeing national grain safety. However, more than half of the grains in China are stored in the hands of farmers, and the storage safety of the grains is an important component of national grain safety. For a long time, the research and the factory pushing of the grain storage technology of farmers are neglected, the grain storage technology of the farmers is very laggard, and huge losses are caused to the nation and people. The invention develops a granary testing and controlling machine.

FIG. 1 is a schematic diagram of the system of the present invention.

In the figure, the temperature and humidity monitoring device comprises a temperature and humidity monitoring module 1, a human body infrared sensing module 2, a single chip microcomputer 3, a display module 4, an alarm module 5, a serial port communication circuit 6, a keyboard matrix 7, a relay 8, a 9 and a fan.

Detailed Description

The utility model provides a granary measurement and control machine, is mainly by humiture monitoring module 1, human infrared induction module 2, singlechip 3, display module 4, alarm module 5, serial communication circuit 6, keyboard matrix 7, relay 8 and fan 9 constitute, its characterized in that: humiture monitoring module 1 and human infrared induction module 2 set up the input at singlechip 3, and display module 4, alarm module 5, serial ports communication circuit 6 and keyboard matrix 7 all are connected with singlechip 3, and relay 8 sets up the output at singlechip 3, and fan 9 is connected with relay 8.

The singlechip 3 adopts an STC89C52 singlechip.

The serial port communication circuit 6 adopts an RS-485 serial bus.

When the device works, the temperature and humidity monitoring module transmits temperature and humidity data collected in the granary to the single chip microcomputer through the converter, the temperature and humidity data are processed by the single chip microcomputer and displayed on the display, and if the detected value exceeds a preset value, the relay receives a signal of the single chip microcomputer to control the fan to work and reduce the temperature and humidity through air flow; the infrared sensing module can monitor personnel close to the granary, the collected signals are transmitted to the single chip microcomputer, and after the signals are processed by the single chip microcomputer, if the personnel appear, the single chip microcomputer transmits the signals to the alarm module to start alarming.
