Hereinafter, a hopper management method of the hopper managing apparatus 500 will be described with reference to FIGS. 5 to 6. FIG.

5 is a flowchart for explaining a hopper management method of the hopper managing apparatus 500 shown in FIG.

1 to 5, a hopper management method according to an embodiment of the present invention supplies power to a hopper 310 of a hopper apparatus 300 and drives a hopper operation timer (S501). The control unit 510 of the hopper management apparatus 500 controls the power supply unit 320 of the hopper apparatus 300 so that the hopper 310 can be driven. Then, the operation time of the hopper 310 is counted by driving the hopper operation timer.

If power is supplied to the hopper 310 in step S501, it is determined whether the remaining amount of the raw material stored in the hopper 310 is equal to or greater than a preset value (S502). The control unit 510 of the hopper management apparatus 500 receives the raw material remaining amount information detected by the residual amount sensor 330 of the hopper apparatus 300 and compares the received raw material remaining amount information with a preset set value . Here, the setting value may mean " Full ".

If the remaining amount of the raw material stored in the hopper 310 is smaller than the set value in step S502, the feeding device 100 is activated and alarmed (S503). The control unit 510 of the hopper management apparatus 500 controls the feeding device 100 to operate and controls the second display unit 533, the first alarm unit 537 and the second alarm unit 539 of the output unit 530 Can be alarmed through.

If it is determined in step S502 that the remaining amount of the raw material stored in the hopper 310 is equal to or greater than the predetermined value, it is determined whether the temperature in the hopper 310 is normal (S504). Whether the temperature in the hopper 310 is normal may be determined by the control unit 510 of the hopper management apparatus 500 receiving the temperature information sensed by the temperature sensor 340 of the hopper apparatus 300, It can be discriminated by comparing with the set value set.

In step S504, if the temperature in the hopper 310 is not normal, a warning is given (S505). The control unit 510 of the hopper management apparatus 500 can alarm through the second display unit 533, the first alarm unit 537 and the second alarm unit 539 of the output unit 530. [

In step S504, if the temperature in the hopper 310 is normal, it is determined whether the humidity in the hopper 310 is normal (S506). Whether or not the humidity in the hopper 310 is normal can be determined by the control unit 510 of the hopper management apparatus 500 receiving the humidity information sensed by the humidity sensor 350 of the hopper apparatus 300, It can be discriminated by comparing with the set value set.

In step S506, if the humidity in the hopper 310 is not normal, an alarm is set (S505) and an interlock of the feeding motor 110 of the feeding device 100 is set (S507). The controller 510 of the hopper management apparatus 500 sets an interlock of the feeding motor 110 of the feeding device 100 so that the feeding motor 110 is no longer driven.

If the humidity in the hopper 310 is normal in step S506, the interlocking of the feeding motor 110 of the feeding device 100 is released (S508).

In step S508, when the interlocking of the feeding motor 110 is released, the management data is transmitted to the monitoring device 700 (S509). The control unit 510 of the hopper management apparatus 500 provides the management data through the wireless communication to the monitoring apparatus 700. The management data provided by the hopper management apparatus 500 includes the raw material remaining amount information in the hopper 310, Whether or not the motor 100 is operated, whether it is alarmed, and whether the interlocking of the feeding motor 110 is set.

Meanwhile, it is possible to determine whether the weekly timer is driven (S510) before performing step S501. The weekly timer is a timer for setting the driving day and the driving time of the dryer 360. The running of the weekly timer means that the current day and time have reached the set day and time. The setting of the weekly timer can be set by the hopper managing apparatus 500 or the monitoring apparatus 700. [ The set weekly timer may be output to the screen as shown in FIG. 3 on the second display unit 533. [ When the operation time of the hopper 310 is reached by the weekly timer, step S501 is performed, and if it is not reached, step S510 is repeated.

6 is a flowchart for explaining another hopper managing method of the hopper managing apparatus 500 shown in FIG.

1 to 6, it is determined whether the amount of the raw material supplied from the feeding device 100 to the hopper 310 is equal to or greater than a preset amount (S601). The control unit 510 of the hopper management apparatus 500 receives the raw material remaining amount information detected by the residual amount sensor 330 of the hopper apparatus 300 and compares the received raw material remaining amount information with a preset set value .

If it is determined in step S601 that the remaining amount of the raw material stored in the hopper 310 is smaller than the predetermined amount in step S502 shown in FIG. 5, if the raw material is supplied to the hopper 310 from the feeding device 100 .

If the amount of the raw material supplied to the hopper 310 from the feeding device 100 is equal to or greater than the preset amount in step S601, the dryer 360 of the hopper device 300 is driven and the drying timer is driven (S602). The control unit 510 of the hopper management apparatus 500 drives the dryer 360 of the hopper apparatus 300 and the drying timer displayed on the first display unit 531 can be counted.

After the step S602 is performed, it is determined whether the operating time of the dryer 360 has reached the set time (S603). When the running time of the dryer 360 has reached the set time, the driving of the dryer 360 is stopped (S604), and if not, the dryer 360 and the drying timer are continuously driven.

After step S604 is performed, it is determined whether the remaining amount of raw material and humidity in the hopper 310 are interlocked with the feeding apparatus 100 (S605). Since the amount of the raw material in the hopper 310 is equal to or greater than the predetermined amount and the dryer 350 has been operated for the set time period in step S605, .

If the remaining amount of raw material and humidity in the hopper 310 are interlocked with the feeding device 100 in step S605, an interlock of the feeding motor 110 of the feeding device 100 is set (S606) (S607).

In step S607, when the interlock of the feeding motor 110 is released, the management data is transmitted to the monitoring device 700 (S608). The control unit 510 of the hopper management apparatus 500 provides the management data via the wireless communication to the monitoring apparatus 700. The management data provided includes the raw material supply information into the hopper 310, And whether or not the interlocking of the feeding motor 110 is set.

If the amount of the raw material supplied from the feeding device 100 to the hopper 310 is smaller than the predetermined amount in step S601, the driving of the residual amount sensor 330 of the hopper device 300 is delayed, (S609). Here, the driving delay timer of the residual amount sensor 330 may be included in the hopper management apparatus 500. [

After the drive delay timer of the remaining amount sensor 330 is driven in step S609, it is determined whether the drive delay time of the remaining amount sensor 330 has reached a predetermined set time (S610). As a result of the determination, if the drive delay time of the residual amount sensor 330 has not reached the preset set time, step S601 is performed again. On the other hand, if the drive delay time of the residual amount sensor 330 has reached the predetermined set time, the remaining amount of raw material is alarmed (S611). The alarm of the shortage of the raw material may be made through the second display unit 533, the first alarm unit 537 and the second alarm unit 539.
