That is, when it is determined whether a load is abnormal using a specific value, when the load temporarily increases, various operating environments such as the number of external devices that are operated cannot be reflected. Accordingly, the present invention does not determine whether a load is abnormal using a set value so as to reflect various operating environments of an external device, but determines whether a load is abnormal using a pattern.

- FIG. 5 is a diagram illustrating an overload determination system for determining whether a production facility is overloaded according to an embodiment of the present invention.
- an overload determination system for determining whether a production facility is overloaded according to an embodiment of the present invention will be described in detail with reference to FIG. 5.
- the overload determination system includes a load measurement module, a measurement data conversion analysis module, and a fire pre-blocking module.
- a load measurement module includes a measurement data conversion analysis module, and a measurement data conversion analysis module.
- a fire pre-blocking module includes a fire pre-blocking module.
- the load measurement module 502 measures the load of a device connected to the system.
- One device may be connected to the device connected to the system, but it is preferable that at least two devices are connected.
- one device is the preceding device and the other is the following device.
- the preceding device may be one device, while the following device may be more than one device.
- the preceding device is a device that is driven prior to driving of the following device
- the following device is a device that is driven after the preceding device is driven. That is, the device proposed in the present invention is composed of a preceding device that is a device that is driven before other devices, and a following device that is driven only after the preceding device is driven.
- the load measurement module 502 measures the load required by the device connected to the system.
- the load measuring module 502 of the present invention includes a preceding device load measuring module that measures a preceding load, which is a load of a preceding device, and a total load measuring module that measures a total load that is a load of the entire preceding device and the following device.

To this end, the measurement data conversion analysis module compares the stored normal load pattern with the converted load pattern, and when it is determined that the converted load pattern is not the normal load pattern, the analysis period is relatively long.
- the measurement data conversion analysis module 504 enlarges and subdivides the load pattern and compares it with the normal load pattern. That is, when it is determined that the converted load pattern is an abnormal load pattern, the measurement data conversion analysis module 504 expands and subdivides the load pattern instead of assuming that the load pattern is an abnormal load pattern, and performs a secondary comparison analysis with the normal load pattern. And, if it is determined that it is an abnormal load pattern by secondary comparison analysis, necessary operations such as power off or external warning are performed.
- the measurement data conversion analysis module 504 Since the measurement data conversion analysis module 504 receives information on whether the preceding device or the following device is operating, it determines whether the load pattern is normal based on the received information on whether the preceding device or the following device is operating. That is, the measurement data conversion and analysis module 504 cannot determine the load used in each of the following devices, but can know whether or not each of the following devices is operated. Accordingly, when an abnormality occurs in the converted load pattern, the measurement data conversion analysis module 504 may indirectly determine whether the abnormal load pattern has occurred due to which of the following devices. That is, if an abnormal load pattern appears after a specific following device is operated in a state in which the following device is operated under the existing normal load pattern, it can be estimated that the abnormal load pattern has occurred due to the corresponding following device.
- the measurement data conversion and analysis module 504 proposed by the present invention may determine whether the load pattern of the following device is abnormal using the load pattern of the following device converted from the received load.
- the measurement data conversion analysis module 504 receives the load of the preceding device from the load measurement module, and generates a load pattern using the received load. The measurement data conversion analysis module 504 determines whether or not an abnormal load pattern of the preceding device is performed using the generated load pattern. To this end, the measurement data conversion analysis module 504 requests to separate and store the normal load pattern for the preceding device and the normal load pattern for the entire following device, and by using the stored normal load pattern for the preceding device, Judge whether or not.
- the measurement data conversion analysis module 504 determines whether the load pattern of the subsequent device is abnormal when it is determined that the load pattern of the preceding device is a normal load pattern, and when the load pattern of the preceding device is an abnormal load pattern, the It does not judge whether there is an abnormality in the load pattern. To explain further, if the load pattern of the preceding device is an abnormal load pattern, the power supplied to the preceding device is cut off without determining the load pattern of the following device. When the operation of the preceding device is stopped, the following device is automatically operated. Stopped.
- the fire pre-blocking module 506 cuts off the power supplied to the preceding device or the following device according to the control command of the measurement data conversion analysis module 504. That is, the pre-fire blocking module 506 cuts off the power supplied to the preceding device or the following device before the fire occurs according to the control command of the measurement data conversion analysis module 504.
- the measurement data conversion analysis module compares and analyzes the load pattern of the preceding device or the following device when it is provided that the preceding device or the following device is operating.
- the normal pattern proposed in the present invention is stored for simple comparison with the load pattern, but it is not judged as an abnormal pattern because the load pattern is different from the normal pattern. For example, when an external device is connected to a power source and operated, starting power is instantaneously increased, and then it starts to stabilize at normal power. However, when the abnormal operation power is repeated after being stabilized or if it is difficult to see the normal pattern, it is determined as an abnormal pattern and the power is cut off.
- the present invention relates to an outlet module capable of blocking a fire in advance and a production facility to which the same, and more particularly, to an outlet module that blocks fire in advance by measuring a load supplied to an external device, and a production facility to which the same.
- the fire pre-blocking outlet module adds a configuration capable of measuring current (or voltage) or power to an existing outlet, or by combining an existing outlet function and a function capable of measuring current (or voltage) or power. , When the magnitude of the external current (or voltage) is measured in real time, and the waveform (or magnitude) of the measured current exceeds the safety factor range that is actively automatically applied according to the voltage and current in standby and normal operation conditions It has the effect of preventing the occurrence of fire due to excessively continuous overcurrent or abnormal operation state by blocking the external current.
