Description

Mobile SILO control system that supplies raw materials using the load of VS motor

The present invention relates to a mobile SILO control system that supplies raw materials using the load of a VS motor.

In general, a silo for supplying mortar powder is temporarily installed at a construction site to temporarily store commercialized mortar powder mixed with cement and sand in advance, and then supplies a set amount to a mixer connected to the discharge port at the bottom, where it is mixed with the supplied water in the mixer to be mortared and then discharged.

That is, a conventional silo device has an inlet pipe and an outlet formed to allow mortar powder to be introduced or discharged into the silo body, and an air discharge pipe is installed in the silo body to discharge air inside the silo body. The air discharge pipe may be installed as a downward pipe or may be installed on the upper part of the silo body.

In a conventional silo device like this, mortar powder introduced into the silo body is transferred to a discharger through a discharge port, and is supplied from the discharger to a mixer by a transfer screw, and then mixed with water in the mixer to become mortar, and then discharged by a supply screw.

However, the conventional silo device as described above has a problem in that the amount of mortar powder discharged through the discharge port varies depending on the amount, i.e., weight, of mortar powder contained in the silo body, making it difficult to maintain a constant supply amount of mortar powder accumulated in the discharger.

Meanwhile, the background technology described above is technical information that the inventor possessed for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the application for the present invention.

FIGS. 9 to 15 are conceptual diagrams of a mobile SILO control system that supplies raw materials using the load of a VS motor according to one embodiment of the present invention.

Referring to FIG. 9, a mobile SILO control system (5) for supplying raw materials using the load of a VS motor according to one embodiment of the present invention may include a control unit (5000) that provides a speed control board for motors, an automatic or manual driving mode, a motor rotation direction control board, and a motor overload alarm, and a silo (1000) that moves to a construction site and mixes and supplies raw materials (mortar, etc.) used at the construction site.

Meanwhile, the silo (1000) can be installed at a construction site and can smoothly supply raw materials (mortar, etc.) depending on the progress, and can be moved after the supply of raw materials at the construction site is completed.

Referring to FIGS. 10 to 13, a silo (1000) according to one embodiment of the present invention may include a storage tank (1001) filled with raw materials (such as mortar), two vibrators (1100) installed on both sides of the lower end of the storage tank (1001) to prevent clumping of raw materials filled inside the storage tank (1001) by causing vibrations to facilitate the supply of raw materials, a stirrer motor (1500) having two gears connected to one motor to supply raw materials filled inside the storage tank (1001) downward, and a VS motor (1900) that mixes raw materials supplied in a certain amount through a rotary motor (1900) and simultaneously discharges the mixed raw materials to a supply position.

Meanwhile, the VS motor (1900) can transmit a signal to brake the agitator motor (1500) to stop the supply of raw materials when the load of the motor increases above a certain level due to the raw materials exceeding a preset amount.

Conversely, when the load of the motor drops below a certain level due to the amount of raw material falling below a preset level, the VS motor (1900) can transmit a signal to drive the stirrer motor (1500) to resupply the raw material.

In addition, the stirrer motor (1500) supplies raw materials to the VS motor (1900), but when the load of the VS motor (1900) rises above a certain level and a signal to brake the stirrer motor (1500) is received, the motor may be stopped.

Conversely, the agitator motor (1500) may be restarted when it receives a signal to drive the agitator motor (1500) when the load of the VS motor (1900) falls below a certain level.

Referring to FIGS. 14 and 15, a control unit (5000) according to one embodiment of the present invention may include a first control unit (5100) having a control panel for controlling the speed of a stirrer motor and a VS motor.

In addition, the control unit (5000) may include a second control unit (5300) equipped with a dashboard for selecting automatic or manual operation of the vibrator (1100), the stirrer motor (1500), and the VS motor (1900), and equipped with a dashboard capable of ON/OFF control in the case of automatic operation.

Additionally, the control unit (5000) may include a third control unit (5500) equipped with a control panel that drives the operation of a vibrator (1100), a stirrer motor (1500), a VS motor (1900), and a water pump (not shown) supplied for mixing of the VS motor (1900).

Additionally, the control unit (5000) may include a fourth control unit (5700) equipped with a control panel for stopping the operation of a vibrator (1100), a stirrer motor (1500), and a VS motor (1900), and a water pump operation for supplying water for mixing raw materials with the VS motor (1900).

In addition, the control unit (5000) may include a switch for emergency stopping the operation of the vibrator (1100), the stirrer motor (1500), and the VS motor (1900), the operation of the water pump that supplies water for mixing raw materials with the VS motor (1900), a switch for selecting the rotation direction of the stirrer motor (1500), and a fifth control unit (5900'', 5900''') that provides an overload alarm of the vibrator (1100), the stirrer motor (1500), and the VS motor (1900).

In the case where the fifth control unit (5000) determines that each motor preset by the manager managing the silo or the field worker is overloaded and determines whether to provide an overload alarm to the manager managing the silo or the field worker, and the standard of N _ov is set to '100' according to the example, in the first example among the two examples described above, the fifth control unit (5900'', 5900''') may not provide an overload alarm to the manager managing the silo or the field worker because it determines that each motor is not overloaded.

Conversely, if the criteria for N _ov for determining whether to provide an overload alarm to the manager or field worker managing the silo when each motor is determined to be overloaded by the manager or field worker managing the silo is set to '100' according to the example, in the second example among the two examples described above, each motor is determined to be overloaded and an overload alarm can be provided to the manager or field worker managing the silo.

However, the standard for the value of N _ov to determine whether to provide an overload alarm to the manager or field worker managing the silo when each motor is judged to be overloaded in the fifth control unit (5000) is set to '100', which is only an example, and the standard can be changed by the manager or field worker managing the silo.

Here, the average overload time of the motor is about 2.5 hours, and the fifth control unit (5000) can provide an overload alarm using [Mathematical Formula 1] only when the continuous operation time of V _op , AM _op , VM _op , and WP _op is 2 hours or more, but is not limited thereto.

As described above, if it is determined that the value preset by the administrator is to be exceeded, the fifth control unit (5900'', 5900''') can calculate a reference value for determining whether to provide an overload alarm by using the continuous operation time of V _op , AM _op , VM _op and WP _op in [Mathematical Formula 4].

Meanwhile, the control unit (5000) can determine the satisfaction of the manager or field worker managing the silo and whether or not to perform inspection of the control unit (5000) based on the satisfaction of the sensitivity for controlling the speed of each motor through the first control unit (5100), the satisfaction of the automatic operation of the second control unit (5300), the time for which the speed control of each motor is applied through the first control unit (5100), the time for which the operation of each motor is applied through the third control unit (5500), and the time for which the operation stop of each motor is applied through the fourth control unit, using the following [Mathematical Formula 5].

[Equation 5]

Here, S _S may mean the satisfaction level of the sensitivity for controlling the speed of each motor through the first control unit (5100), A _O may mean the satisfaction level for the automatic operation of the second control unit (5300), S _AT may mean the time for which the speed control of each motor is applied through the first control unit (5100), ON AT may mean the time for which the driving of each motor is applied through the third control unit (5500), OFF _AT may mean the time for which the driving stop of each motor is applied through the fourth control unit, _and S ₁ may mean a value that serves as a standard for determining the satisfaction level of a manager or field worker managing a silo and whether or not to perform an inspection of the control unit (5000) accordingly.

It can mean the satisfaction level input from the manager or field worker managing the above-mentioned silo in numerical form, and S _AT , ON _AT and OFF _AT can be entered as numerical units of time, and 2 hours and 30 minutes can be entered as 2.5, and 3 hours can be entered as 3.

Here, S _S and A _O can be assigned values closer to 10 as the satisfaction of the manager or field worker managing the silo increases, and values closer to 1 as the satisfaction of the manager or field worker managing the silo decreases.

Meanwhile, S _AT + ON _AT + OFF _AT can be substituted with a value other than '0'.

For example, if S _S is 8, A _O is 9, S _AT is 0.16, ON _AT is 0.16, and OFF _AT is 0.16, then S ₁ can be calculated as 150, and if S _S is 3, A _O is 2, S _AT is 0.67, ON _AT is 0.5, and OFF _AT is 0.67, then S ₁ can be calculated as 3.26.

The larger the value of S ₁ produced, the higher the satisfaction of the manager or field worker managing the silo can be judged, and accordingly, it can be judged that inspection of the control unit (5000) is not performed.

Conversely, the smaller the value of S ₁ produced, the lower the satisfaction of the manager or field worker managing the silo can be judged, and accordingly, it can be judged that inspection of the control unit (5000) is performed.

Among the two examples described above, since the first example is calculated to have a larger value than the second example, it can be judged that the satisfaction of the manager or field worker managing the silo is high, and accordingly, inspection of the control unit (5000) may not be performed.

Conversely, since the second example is calculated to be a smaller value than the first example, the satisfaction of the manager or field worker managing the silo may be judged to be low, and accordingly, an inspection of the control unit (5000) may be performed.

Meanwhile, the standard for the value of S ₁ for determining the satisfaction of the manager or field worker managing the silo and whether to perform inspection of the control unit (5000) accordingly can be set in advance by the manager or field worker managing the silo.

For example, if the standard for the value of S ₁ for determining the satisfaction of a manager or field worker managing a silo and whether to perform an inspection of the control unit (5000) accordingly is set to '100', if S ₁ is calculated to be a value greater than '100', the satisfaction of the manager or field worker managing the silo may be judged to be high, and accordingly, an inspection of the control unit (5000) may not be performed.

In the case where the standard of S ₁ for determining whether to perform an inspection of the control unit (5000) based on the satisfaction of the manager or field worker managing the silo is set to '100' according to the example, among the two examples described above, in the case of the first example, the control unit (5000) may determine that the satisfaction of the manager or field worker managing the silo is high and may not perform an inspection of the control unit (5000).

Conversely, if the control unit (5000) sets the standard of S ₁ to '100' according to the example for determining the satisfaction of the manager or field worker managing the silo and whether to perform an inspection of the control unit (5000) accordingly, among the two examples described above, in the second example, the control unit (5000) determines that the satisfaction of the manager or field worker managing the silo is low, and thus the control unit (5000) can perform an inspection.

However, setting the standard of S ₁ to '100' for determining whether to perform inspection of the control unit (5000) is only an example, and the standard may be changed by the manager of the control unit (5000).

Meanwhile, the mobile SILO control system (5) for supplying raw materials using the load of the VS motor proposed by the present invention can determine the level of satisfaction of the manager or field worker managing the silo with respect to the system based on the satisfaction with the storage space capacity of the storage tank (1001), the satisfaction with the supply speed of raw materials, the satisfaction with the accuracy of the raw material supply amount, the satisfaction with the control speed of each motor using the control unit (5000), and the satisfaction with the configuration of the control unit (5000) based on the value calculated using [Mathematical Formula 6] below, and can determine whether to perform an inspection of the system (5) based on the level of satisfaction.

[Equation 6]

Here, C _st may mean satisfaction with the storage space capacity of the storage tank (1001), SR may mean satisfaction with the supply speed of raw materials, SA may mean satisfaction with the accuracy of the raw material supply amount, CS may mean satisfaction with the control speed of each motor using the control unit (5000), CU may mean satisfaction with the configuration of the control unit (5000), and S ₂ may mean a value that serves as a standard for judging the satisfaction with the use of the corresponding system by a manager or field worker managing the silo.

Here, C _st , SR, SA, CS and CU can be assigned values closer to 10 as the satisfaction of the manager or field worker managing the silo increases, and can be assigned values closer to 1 as the satisfaction of the manager or field worker managing the silo decreases.

For example, if C _st is 7, SR is 7, SA is 9, CS is 9, and CU is 8, S ₂ can be calculated as 6.95, and if C _st is 3, SR is 3, SA is 4, CS is 3, and CU is 2, S ₂ can be calculated as 3.97.

The mobile SILO control system (5) that supplies raw materials using the load of the VS motor is judged to have a higher satisfaction level for the system of the manager or field worker managing the silo as the value of S ₂ produced is higher, and thus the inspection of the system (5) is likely to be postponed.

Conversely, the smaller the value of S ₂ produced, the lower the satisfaction level of the manager or field worker managing the silo with the system is judged to be, and thus the probability that an inspection of the system (5) will be performed increases.

Among the two examples described above, since the first example is calculated to have a larger value than the second example, it is judged that the satisfaction level of the manager or field worker managing the silo with the system is high, and thus the inspection of the system (5) is likely to be postponed.

Conversely, since the second example is calculated to have a smaller value than the first example, it is judged that the satisfaction of the administrator or field worker managing the silo with the system is low, and thus the probability of performing an inspection of the system (5) may increase.

Meanwhile, the mobile SILO control system (5) that supplies raw materials using the load of the VS motor can be used as a standard for determining whether the manager or field worker managing the silo is satisfied with the system and whether a system inspection is performed.

For example, if the standard for the value of S ₂ for determining whether or not a manager or field worker managing a silo is satisfied with the system and whether or not to perform a system inspection is set to '5', if S ₂ is calculated to be a value greater than '5', the manager or field worker managing a silo is judged to be highly satisfied with the system, and inspection of the system (5) may be postponed.

In the case where the mobile SILO control system (5) that supplies raw materials by using the load of the VS motor sets the standard for the value of S ₂ to '5' for determining whether the manager managing the silo or the field worker is satisfied with the system and whether to perform a system inspection, among the two examples described above, in the first example, the mobile SILO control system (5) is determined to have a high level of satisfaction with the system by the manager managing the silo or the field worker, and therefore the inspection of the system (5) can be postponed.

Conversely, if the standard for the value of S ₂ for determining whether or not the administrator or field worker managing the silo is satisfied with the system and whether or not to perform a system inspection is set to '5', in the case of the second example among the two examples described above, the administrator or field worker's satisfaction with the system is determined to be low, and thus an inspection of the system (5) can be performed.

However, setting the standard for the value of S ₂ to determine whether the manager or field worker managing the silo is satisfied with the use of the system and whether a system inspection is performed for the mobile SILO control system (5) that supplies raw materials using the load of the VS motor is only an example, and the standard can be changed by the manager or field worker managing the silo.

With reference to FIGS. 23 to 28, the concept and configuration of a mobile SILO control system for supplying raw materials using the load of a VS motor according to one embodiment of the present invention can be understood more specifically.

The storage tank (101) may refer to a space in which raw materials (mortar, etc.) are filled inside. In other words, a storage space may be provided so that raw materials can be filled inside.

The rotary motor (500) can be driven to control the supply amount of raw material delivered through the screw motor (300).

The VS motor (700) can be driven to mix a certain amount of raw material supplied through the rotary motor (500) and simultaneously discharge the mixed raw material to the supply position.

Referring to FIGS. 7 and 8, a control unit (50) according to another embodiment of the present invention may include a first control unit (51), a second control unit (53), a third control unit (55), a fourth control unit (57), and a fifth control unit (59', 59'', 59''').

Meanwhile, the fifth control unit (59', 59'', 59''') can determine whether to provide an overload alarm using [Mathematical Formula 1] below based on the continuous operation time of the vibrator, the continuous operation time of the screw motor, the continuous operation time of the rotary motor, the continuous operation time of the VS motor, and the continuous operation time of the water pump.

Here, V _op may mean the continuous operation time of the vibrator, SM _op may mean the continuous operation time of the screw motor, RM _op may mean the continuous operation time of the rotary motor, VM _op may mean the continuous operation time of the VS motor, WP _op may mean the continuous operation time of the water pump, and N _ov may mean a value that serves as a reference for determining whether to provide an overload alarm.

Here, V _op , SM _op , RM _op , VM _op , and WP _op represent the operating time, which can be entered as a numerical value in time units, with 2 hours and 30 minutes being entered as 2.5 and 3 hours as 3.

For example, if V _op is 2.5, SM _op is 2.5, RM _op is 2.5, VM _op is 2.5, and WP _op is 2.5, then N _ov can be calculated as 28.75, and if V _op is 6, SM _op is 6, RM _op is 6, VM _op is 6, and WP _op is 6, then N _ov can be calculated as 132.

The fifth control unit (59', 59'', 59''') determines that each motor is overloaded as the value of N _ov produced is larger, and thus the probability of providing an overload alarm to the manager or field worker managing the silo may increase.

Conversely, the smaller the value of N _ov produced, the less likely it is that each motor will be judged to be overloaded, and thus the less likely it is that an overload alarm will be provided to the silo manager or field worker.

Of the two examples described above, the first example yields a lower value than the second example, which may reduce the likelihood that each motor will be judged not to be overloaded, thereby providing an overload alarm to the silo manager or field worker.

Conversely, the second example may produce a larger value than the first, increasing the likelihood that each motor will be judged to be overloaded, which will trigger an overload alarm to the silo manager or field operator.

Meanwhile, the fifth control unit (50) determines that each motor is overloaded and determines whether to provide an overload alarm to the manager or field worker managing the silo. The standard for the value of N _ov can be preset by the manager or field worker managing the silo.

For example, if the standard for the value of N _ov for determining whether to provide an overload alarm to the manager or field worker managing the silo when each motor is judged to be overloaded is set to '100', if N _ov is calculated to be a value greater than '100', each motor is judged to be overloaded and an overload alarm can be provided to the manager or field worker managing the silo.

The fifth control unit (50) determines whether to provide an overload alarm to the manager managing the silo or the field worker when each motor preset by the manager managing the silo or the field worker is determined to be overloaded. In the case where the standard of N _ov is set to '100' according to the example, among the two examples described above, in the first example, the fifth control unit (59', 59'', 59''') may not provide an overload alarm to the manager managing the silo or the field worker when each motor is determined not to be overloaded.

Conversely, if the criteria for N _ov for determining whether to provide an overload alarm to the manager or field worker managing the silo when each motor is determined to be overloaded by the manager or field worker managing the silo is set to '100' according to the example, in the second example among the two examples described above, each motor is determined to be overloaded and an overload alarm can be provided to the manager or field worker managing the silo.

However, the standard for the value of N _ov to determine whether to provide an overload alarm to the manager or field worker managing the silo when each motor is judged to be overloaded in the fifth control unit (50) is set to '100', which is only an example, and the standard can be changed by the manager or field worker managing the silo.

Here, the average overload time of the motor is about 2.5 hours, and the fifth control unit (50) can provide an overload alarm using [Mathematical Formula 1] only when the continuous operation time of V _op , SM _op , RM _op , VM _op , and WP _op is 2 hours or more, but is not limited thereto.

As described above, if it is determined that the value preset by the administrator is to be exceeded, the fifth control unit (59', 59'', 59''') can calculate a reference value for determining whether to provide an overload alarm by using the continuous operation time of V _op , SM _op , RM _op , VM _op and WP _op in [Mathematical Formula 1].

Meanwhile, the control unit (50) can determine the satisfaction of the manager or field worker managing the silo and whether or not to perform inspection of the control unit (50) based on the satisfaction of the sensitivity for controlling the speed of each motor through the first control unit (51), the satisfaction of the automatic operation of the second control unit (53), the time for which the speed control of each motor is applied through the first control unit (51), the time for which the drive of each motor is applied through the third control unit (55), and the time for which the drive stop of each motor is applied through the fourth control unit, using the following [Mathematical Formula 2].

[Equation 2]

Here, S _S may mean the satisfaction level of the sensitivity for controlling the speed of each motor through the first control unit (51), A _O may mean the satisfaction level for the automatic operation of the second control unit (53), S _AT may mean the time for which the speed control of each motor is applied through the first control unit (51), ON AT may mean the time for which the driving of each motor is applied through the third control unit (55), OFF _AT may mean the time for which the driving stop of each motor is applied through the fourth control unit, _and S ₁ may mean a value that serves as a standard for determining the satisfaction level of a manager or field worker managing a silo and whether or not to perform an inspection of the control unit (50) accordingly.

It can mean the satisfaction level input from the manager or field worker managing the above-mentioned silo in numerical form, and S _AT , ON _AT and OFF _AT can be entered as numerical units of time, and 2 hours and 30 minutes can be entered as 2.5, and 3 hours can be entered as 3.

Here, S _S and A _O can be assigned values closer to 10 as the satisfaction of the manager or field worker managing the silo increases, and values closer to 1 as the satisfaction of the manager or field worker managing the silo decreases.

Meanwhile, S _AT + ON _AT + OFF _AT can be substituted with a value other than '0'.

For example, if S _S is 8, A _O is 9, S _AT is 0.16, ON _AT is 0.16, and OFF _AT is 0.16, then S ₁ can be calculated as 150, and if S _S is 3, A _O is 2, S _AT is 0.67, ON _AT is 0.5, and OFF _AT is 0.67, then S ₁ can be calculated as 3.26.

The higher the value of S ₁ produced, the higher the satisfaction of the manager or field worker managing the silo can be judged, and accordingly, it can be judged that inspection of the control unit (50) is not performed.

Conversely, the smaller the value of S ₁ produced, the lower the satisfaction of the manager or field worker managing the silo can be judged, and accordingly, it can be judged that inspection of the control unit (50) is performed.

Among the two examples described above, since the first example is calculated to have a larger value than the second example, it can be judged that the satisfaction of the manager or field worker managing the silo is high, and accordingly, inspection of the control unit (50) may not be performed.

Conversely, since the second example is calculated to be a smaller value than the first example, the satisfaction of the manager or field worker managing the silo can be judged to be low, and accordingly, an inspection of the control unit (50) can be performed.

Meanwhile, the standard for the value of S ₁ for determining the satisfaction of the manager or field worker managing the silo and whether to perform inspection of the control unit (50) accordingly can be set in advance by the manager or field worker managing the silo.

For example, if the standard for the value of S ₁ for determining the satisfaction of a manager or field worker managing a silo and whether to perform an inspection of the control unit (50) accordingly is set to '100', if S ₁ is calculated to be a value greater than '100', the satisfaction of the manager or field worker managing the silo may be judged to be high, and accordingly, an inspection of the control unit (50) may not be performed.

In the case where the standard of S ₁ for determining whether to perform an inspection of the control unit (50) based on the satisfaction of the manager or field worker managing the silo is set to '100' according to the example, among the two examples described above, in the case of the first example, the control unit (50) may determine that the satisfaction of the manager or field worker managing the silo is high and may not perform an inspection of the control unit (50).

Conversely, if the control unit (50) sets the standard of S ₁ to '100' according to the example for determining the satisfaction of the manager or field worker managing the silo and whether to perform an inspection of the control unit (50) accordingly, among the two examples described above, in the second example, the control unit (50) determines that the satisfaction of the manager or field worker managing the silo is low, and thus the control unit (50) can perform an inspection.

However, setting the standard of S ₁ to '100' for determining whether to perform inspection of the control unit (50) is only an example, and the standard can be changed by the manager of the control unit (50).

Meanwhile, the mobile SILO control system (1) proposed by the present invention can determine the level of satisfaction of a manager or field worker managing a silo with respect to the system based on the satisfaction with the storage space capacity of the storage tank (101), the satisfaction with the supply speed of raw materials, the satisfaction with the accuracy of the raw material supply amount, the satisfaction with the control speed of each motor using the control unit (50), and the satisfaction with the configuration of the control unit (50), based on the value calculated using [Mathematical Formula 3] below, and can determine whether to perform an inspection of the system (1) based on the level of satisfaction.

[Equation 3]

Here, C _st may mean satisfaction with the storage space capacity of the storage tank (101), SR may mean satisfaction with the supply speed of raw materials, SA may mean satisfaction with the accuracy of the raw material supply amount, CS may mean satisfaction with the control speed of each motor using the control unit (50), CU may mean satisfaction with the configuration of the control unit (50), and S ₂ may mean a value that serves as a standard for judging the satisfaction with the use of the corresponding system by a manager or field worker managing the silo.

Here, C _st , SR, SA, CS and CU can be assigned values closer to 10 as the satisfaction of the manager or field worker managing the silo increases, and can be assigned values closer to 1 as the satisfaction of the manager or field worker managing the silo decreases.

For example, if C _st is 7, SR is 7, SA is 9, CS is 9, and CU is 8, S ₂ can be calculated as 6.95, and if C _st is 3, SR is 3, SA is 4, CS is 3, and CU is 2, S ₂ can be calculated as 3.97.

The higher the value of S ₂ produced by the mobile SILO control system (1), the higher the satisfaction of the manager or field worker in charge of managing the silo with the system is judged to be, and thus, the higher the probability that inspection of the system (1) will be postponed.

Conversely, the smaller the value of S ₂ produced, the lower the satisfaction level of the manager or field worker managing the silo with the system is judged to be, and thus the higher the probability that an inspection of the system (1) will be performed.

Among the two examples described above, since the first example is calculated to have a larger value than the second example, it is judged that the satisfaction level of the manager or field worker managing the silo with the system is high, and thus the inspection of the system (1) is likely to be postponed.

Conversely, since the second example is calculated to be a smaller value than the first example, it is judged that the satisfaction of the administrator or field worker managing the silo with the system is low, and thus the probability of performing an inspection of the system (1) may increase.

Meanwhile, the mobile SILO control system (1) can be used as a standard to determine whether the manager or field worker managing the silo is satisfied with the system and whether a system inspection is performed.

For example, if the standard for the value of S ₂ for determining whether or not a manager or field worker managing a silo is satisfied with the system and whether or not to perform a system inspection is set to '5', if S ₂ is calculated to be a value greater than '5', the manager or field worker managing a silo is judged to be highly satisfied with the system, and inspection of the system (1) may be postponed.

In the case where the criterion for the value of S ₂ for determining whether or not the manager or field worker managing the silo is satisfied with the system and whether or not to perform a system inspection is set to '5', among the two examples described above, in the first example, the silo control system (1) is determined to have a high level of satisfaction with the system by the manager or field worker managing the silo, and thus the inspection of the system (1) may be postponed.

Conversely, if the standard for the value of S ₂ for determining whether or not the administrator or field worker managing the silo is satisfied with the system and whether or not to perform a system inspection is set to '5', in the second example among the two examples described above, the administrator or field worker's satisfaction with the system is determined to be low, and thus an inspection of the system (1) can be performed.

However, setting the standard for the value of S ₂ to '5' for judging whether the manager or field worker managing the silo in the mobile SILO control system (1) is satisfied with the system and whether a system inspection is performed is only an example, and the standard can be changed by the manager or field worker managing the silo.

FIGS. 16 to 22 are drawings for explaining the concept of a mobile SILO control system according to another embodiment of the present invention and the VS motor being stopped after a set time (0 to 10 seconds) using a timer when automatic operation ends.

Referring to FIGS. 16 to 22, when a time setting is input through a timer provided through a second control unit, when automatic operation ends, the VS motor is turned off after the time set through the timer has elapsed, and the remaining raw materials in the mixer are discharged, and then the mixer can be stopped.

That is, the mobile SILO control system according to another embodiment of the present invention can set a time for the VS motor to stop after automatic operation ends, thereby discharging the raw material remaining in the mixer for the set time and then stopping the VS motor to prevent hardening of the raw material remaining.

The reason why the VS motor is stopped after a set time when the automatic operation is turned off using a timer is that when all motors are stopped when the automatic operation is turned off, the raw materials remaining in the mixer harden, and when the mixer is restarted after a certain period of time, the operation may not be possible due to the hardening of the raw materials.

To prevent this, when the automatic operation is turned off, other motors stop, but only the VS motor stops after a set time, which is to prevent the raw material remaining in the mixer from hardening by discharging it during the set time.

Through this, the mobile SILO control system (1) according to another embodiment of the present invention provides an automatic driving function, but the time for which the VS motor is turned off when automatic driving ends can be set by a manager or field worker, thereby maximizing work efficiency.

The embodiments described above are provided for illustrative purposes only, and those skilled in the art will readily appreciate that the embodiments described above can be readily modified into other specific forms without altering the technical concepts or essential characteristics of the embodiments described above. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, components described as being single may be implemented in a distributed manner, and similarly, components described as being distributed may be implemented in a combined manner.
