In the present invention, in the apparatus for carrying out storage drying of grains in a plurality of silos, the silos 10 form a cylindrical bin by assembling a galvanized steel ring. The upper layer of the bin is provided with a stirrer 12 for drying and storing the room temperature ventilation, and an input conveyor 11 for transporting the grain into the silo, and at the bottom surface, transferring the grain stored in the bin to the outside. The exhaust auger 14 and the air filling chamber below the bottom surface are provided with a blower 15 and a white leaf 16 for measuring external weather information. In addition, a heater on the flow path of the blower 15 (not shown) is provided.

According to the present invention, a temperature-humidity measuring device 20 that detects signals corresponding to temperature and humidity is mounted to be able to move up and down at the center of the silo 10. Conventionally, the configuration in which the temperature sensor is installed on the wall surface of the silo 10 is convenient because the trajectory interference of the stirrer 12 is small, but the reliability and representativeness of the temperature measurement value are insufficient, and thus it is highly dependent on the direct measurement of the manager. Summary of the Invention The present invention is directed to a configuration for detecting temperature and humidity by rising or falling as necessary in the center of the silo 10.

Figure 2 is an enlarged view showing a temperature and humidity meter according to the present invention.

The temperature and humidity measuring device 20 is connected to a cable end part to detect temperature and humidity, a TDR sensor 21, a reel 22 winding a cable connected to the TDR sensor 21, and driving of the reel 22. The electronic clutch 24 which controls the electronic clutch 24, the drive motor 23 which drives the electronic clutch 24, and enables the raising / lowering of the TDR sensor 21, and stirring between the reel 22 and the driving motor 23, Torque sensor 25 for detecting the mechanical overload according to the measurement, and the vibration motor 26 to penetrate into the grain by giving a fine vibration to the TDR sensor 21 is provided with a temperature sensor, although not shown.

3 is a circuit block diagram of a PLC panel according to the present invention.

The PLC panel 41 converts the signals input from the temperature sensor of the silo 10, the TDR sensor 21, the torque sensor 25 through the signal converter 30, and at the same time, the agitator 12 and the discharge auger 14. , A blower 15, a heater, a drive motor 23, a vibration circuit 26 for operating the drive circuit is provided. In addition, a memory is provided for storing the programs and data necessary for the control so that they can be updated as necessary. For example, the speed of rotating the stirrer 12 while rotating in the silo 10, the air blowing amount of the blower 15, and the heater The data on the heat generation amount is stored in the RPC main server 42 via the PLC panel 41.

At this time, the PLC panel 41 of the present invention includes a control program for the temperature and humidity measuring device 20 and the data is sent to the RPC main server 42 and stored, and detailed operation thereof will be described with reference to FIG. 4.

The present invention further advances the man-machine interface (MMI) method for the expensive grain, and automatically manages the temperature and humidity of the grain as well as the silo of the grain processing plant (RPC) and the satellite facility (DSC). Through monitoring the inside and outside temperature and humidity of the facility, the principle of Equilibrium Moisture Content (EMC) calculation of the stored grains and the dedicated PLC control program can be used to control the stirrer (12) and the blower (15) without restriction of time and place. Through remote control, it checks the operation status of the machine, internal and external temperature and humidity of grain, and enables forced or automatic operation if necessary.In case of emergency, RPC main server (42) warning window display and mobile phone text transmission Multiple emergency alarm systems, such as the service 52, are secured so that they can be used as evidence of the operation status of the device or the data of grain management.

In the first step (S10) of the present invention, when the electronic clutch 24 is turned off and the TDR sensor 21 of the temperature and humidity measuring instrument 20 falls to its own weight and the vibration motor 26 is operated to generate minute vibrations, the TDR sensor (21) is shaken and penetrated into the grain. On the contrary, when the electronic clutch 24 is turned on, power is transmitted by the driving motor 23 so that the reel 22 rotates to wind the TDR sensor 21. As described above, the TDR sensor 21 naturally detects a signal for temperature and humidity while descending or rising the grain, and sends the signal to the PLC panel 41 through the signal converter 30. Forcing the TDR sensor 21 into the center of the silo 10 is likely to cause damage to related components by the resistance of the grain.

In the second step (S20) of the present invention, the signal from the torque sensor 25 and the temperature and humidity meter 20 in the silo and the external temperature and humidity from the external lobe 16 to the PLC panel 41. This step converts the data needed for control and storage before it is sent.

In the third step (S30) of the present invention, the final moisture content is determined by setting the drying time in consideration of the air volume, drying temperature, grain temperature (static pressure), relative humidity, etc., and then monitoring and control for storage for a certain period of time is performed. do. For reference, processing of rice has good food and yield when the humidity is 16%. When the final water content is up to + 2%, the heater is automatically turned off, and the final drying is performed by the natural blowing of the blower 15 and the stirrer 12. The blower 15 and the stirrer 12 are continuously operated to within 2 ° C. of the outside air temperature to allow sufficient cooling and tempering to proceed to the storage process. Ventilation, agitation, and heating are selected according to the grain temperature difference between the grains in the silo 10. In particular, since the humidity of the upper curved layer is severe, the signal of the TDR sensor 21 should be checked in real time. The rising / lowering period data of the TDR sensor 21 is stored in the RPC main server 42.

Finally, the data transmission step (S40) is a process in which the PLC panel 41 transmits and receives data and control signals necessary for the RPC main server 42 and the main control panel 43. When the PLC panel 41 passes the main control panel 43 as an input device, the PLC panel 41 operates by the data, and the operated data is stored and processed by the RPC main server 42 via the PLC panel 41 again. to be.

By using the apparatus of the present invention, it is possible to check and manipulate grain temperature, moisture content, humidity, machine operation, etc. using a computer or other communication input device in a manager's office or a specific region without going into the silo 10. Will be. If necessary, it can be used by printing out data such as whether the machine is running, grain temperature and humidity, and outside air on a printer or CD.

Although it is not in the city, it can respond quickly to grain management by immediately sending and receiving to the operator or related manager through network or wired / wireless communication when detecting abnormal condition of grain.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
