An object of the present invention is to provide a sensing device that detects a power outage in a set area, automatically performs a switching operation according to the power outage, or separately calculates a normal power amount and an emergency power amount.

The sensing device of the present invention includes a first acquisition unit that obtains a first monitoring result of first power supplied from phase power to a load; A second acquisition unit for obtaining a second monitoring result of second power supplied to the load from a generation source distinct from the phase power source; may include.

The sensing method of the present invention includes an acquisition step of obtaining a first monitoring result of first power supplied from a phase power source to a load and obtaining a second monitoring result of second power supplied from a power generation source to the load; a discrimination step of distinguishing whether the power supplied to the load is the first power or the second power by using a result of the first monitoring and the second monitoring; and an integrating step of classifying the amount of power used by the load into the first amount of power and the second amount of power and integrating the amount of power used by the load by using the classification result of the division unit.

The sensing device of the present invention may sense first power provided from a phase power source for a load and detect second power provided from a power generation source for a load, respectively.

The first monitoring result of the first power and the monitoring result of the second power detected by the sensing device may be used for various purposes, such as power supplier switching and power consumption classification and integration.

Power provider switching may include switching to which provider the power provided to the load may be determined.

For example, if it is determined that the first power exists according to the analysis of the first monitoring result, the sensing device may automatically select phase power as a power supplier for the load. Specifically, the sensing device may electrically connect the load and the phase power source and disconnect the electrical connection between the load and the remaining sources, for example, the power generation source.

As another example, if it is determined that the first power is stopped and the second power exists according to the analysis of the first monitoring result and the second monitoring result, the sensing device may automatically select a power generation source as a power supplier for the load. Specifically, the sensing device may electrically connect the load and the generation source and disconnect the electrical connection between the load and the phase power source.

That is, according to the sensing device of the present invention, in a situation where a plurality of power providers exist, one power provider can be clearly selected at a point in time for a specific load. In this case, if only the identification information of the corresponding time and the corresponding power provider is identified, a system in which billing at the corresponding time is provided to the corresponding power provider may be implemented. As a result, when the first monitoring result and the second monitoring result are used, an environment in which power consumption supplied to a specific load is divided by power supplier and integrated can be provided.

Looking at it from another point of view, a source providing power used by each load may be identified by the sensing device. According to this, since billing for each source is possible, an environment in which a plurality of power providers can appear can be prepared.

In addition, an environment in which a user can select an appropriate provider according to services provided by various power providers may be provided.

The first acquisition unit 110 may obtain a first monitoring result of the first power supplied from the phase power source 19 to the load 90 . The first power may correspond to phase power or commercial power. The first power may be supplied by, for example, a power supplier such as a government agency such as Korea Electric Power Corporation.

A second monitor 20 may be provided to monitor the second power in the second line connecting the emergency power source 80 and the main input terminal.

For example, the first monitor 10 and the second monitor 20 may include a kind of meter that measures the amount of power.

The first monitor 10 may output a first monitoring result including the fact that the first power is supplied when power flows through the first line.

The second monitor 20 may output a second monitoring result including the supply of the second power when power flows through the second line.

On the other hand, an emergency power supply 80 may be provided to receive the first power or the second power with priority over 'LOAD' of the load 90 .

The emergency power source 80 may function as a source for providing power to various safety facilities such as elevators and emergency lights that must always operate regardless of power outages. Looking from another point of view, 'emergency power' described in this specification may ultimately be interpreted as meaning safety facilities and emergency facilities that have a higher power supply priority than the general load 90 .

The emergency power supply 80 is a phase power source 19 and a power generation source ( 29) can be electrically connected.

A switching unit may be provided that switches between the supply of the first power to the load 90 and the supply of the second power to the load 90 by using the first monitoring result and the second monitoring result.

Switching performed by the switching unit may mean changing a connection line or a connection line between the load 90 , the phase power supply 19 , and the power generation source 29 .

A first switching unit 31 and a second switching unit 32 may be provided in the switching unit.

The first switching part 31 may be installed at the main input end of the 'LOAD' of the load 90 (same as the position of the first switching part 31 in the drawing). The second switching unit 32 is an emergency input terminal of the emergency power source 80 to which the first power or the second power is supplied with priority over the 'LOAD' of the load 90 (same as the position of the second switching unit 32 in the drawing). ) can be installed.

The first switching unit 31 may be first switched so that any one of the phase power supply 19 and the power generation source 29 is connected to the load 90 .

The second switching unit 32 may be second switched so that any one of the phase power source 19 and the power generation source 29 is connected to the emergency power source 80 .

The first switching and the second switching may be performed using at least one of the first monitoring result and the second monitoring result. In other words, the first switching unit 31 and the second switching unit 32 may operate based on the first monitoring result and the second monitoring result.

A first mode, a second mode, a third mode, and a fourth mode may be defined.

In the first mode, the first switching unit 31 is switched so that the phase power supply 19 and the load 90 are connected, and the second switching unit 32 is switched so that the phase power supply 19 and the emergency power source are connected. can be a mod

When a blackout in which the first power supplied from the phase power source 19 is stopped is detected, the first switching unit 31 and the second switching unit 32 operating in the first mode may first operate in the second mode. .

In a state in which a power outage is detected, if surplus power remaining after being supplied to the emergency power supply 80 among the second power exists, the first switching unit 31 and the second switching unit 32 supply the emergency power supply 80 with the second power supply. It may operate in the third mode while maintaining a state in which power is supplied. According to the third mode, not only the emergency power supply 80 but also the load 90 may receive second power when the phase power supply 19 fails.

The first switching unit 31 and the second switching unit 32 may automatically return to the first mode when resumption of supply of the first power is detected through the analysis of the first monitoring result and the second monitoring result.

3 is a schematic diagram showing a power grid in a comparative embodiment.

According to the comparative embodiment, a single switch 39 is disposed between the phase power source 19 and the power generation source 29 . An emergency power supply 80 is connected to the switchover 39.

The load 90 and the metering module 70 for measuring the power consumption of the load 90 are connected between the phase power source 19 and the switch 39. The load 90 and the weighing module 70 may be in a state of being fixedly connected to the phase power source 19 regardless of the operation of the switcher 39 .

A single switch 39 may connect the emergency power source 80 to the phase power source 19 or connect the emergency power source 80 to the power generation source 29 .

According to the comparative embodiment, the switchover 39 may connect the emergency power source 80 and the phase power source 19 normally when the first power is normally supplied. According to this, the first power may be supplied to the load 90 and the emergency power source 80 . When the supply of the first power is stopped, the switcher 39 may connect the power generation source 29 and the emergency power source 80.

In order to prevent a reverse phenomenon in which the second power of the power generation source 29 flows back to the phase power source 19, the switch 39 limits the situation in which the phase power source 19 and the power source 29 are electrically connected. A switching operation can be performed.

In order to manage the first power and the second power while preventing the reverse phenomenon using a single switch 39, the surplus power of the second power remaining after being supplied to the emergency power source 80 is supplied to the load 90 The road that can be can be blocked.

Also, according to the comparative embodiment, there is no means for determining whether the power supplied to the load 90 is the first power or the second power. Therefore, if the first power and the second power are mixedly supplied to the load 90, there is a problem in that the electricity rate system is disturbed.

Therefore, a comparative embodiment having a single transfer device 39 is applied to the field in reality to prevent the reversal phenomenon and to maintain the rate system. As a result, due to a practical problem, it is difficult for the load 90 to use the second power of the power generation source 29 when a power failure based on the phase power source 19 occurs.

The transfer unit of the present invention is disposed between the phase power source 19, the power generation source 29, and the load 90, and can always disconnect the electrical connection between the phase power source 19 and the power generation source 29. While selectively connecting the phase power source 19 and the power generation source 29 with respect to the load 90, the first switching unit 31 to maintain the phase power source 19 and the power generation source 29 in a disconnected state at all times And two second switching parts 32 may be provided.

When the first power is supplied from the phase power source 19, the transfer unit is in the first mode of electrically connecting the phase power source 19 and the load 90 and electrically disconnecting the power generation source 29 and the load 90. can be switched.

When the supply of the first power through the phase power source 19 is interrupted, the transfer unit electrically connects the power generation source 29 and the load 90 and electrically disconnects the phase power source 19 and the load 90. It can be switched to the third mode.

When the supply of the first power to the load 90 is interrupted and then resumed, the transfer unit may determine re-supply of the first power through the first monitoring result and the second monitoring result.

When re-supply of the first power is determined, the transfer unit may automatically switch from the third mode to the first mode.

According to the above first acquisition unit 110 , the second acquisition unit 120 , and the transfer unit, an environment capable of supplying second power to the load 90 in terms of hardware can be provided. In order to provide an environment capable of supplying the second power to the load 90 as a policy, the division unit 130 and the integration unit 150 may be used.

When the first acquisition unit 110, the second acquisition unit 120, the division unit 130, and the integration unit 150 are provided in the electricity meter 100, a new electricity meter 100 equipped with a sensing device is required. However, the load 90 of the server 200 can be greatly reduced.

The classifier 130 can distinguish whether the power supplied to the load 90 is the first power or the second power by using the first monitoring result and the second monitoring result. The classification result of the classification unit 130 may be used to determine whether the power supplied to the load 90 is static, for example, whether it is the first power or the second power. Alternatively, the classifier 130 may distinguish between a first amount of power of the first power supplied to the load 90 and a second amount of power of the second power supplied to the load 90 .

The server 200 may provide the integration result to the electricity meter 100, and the electricity meter 100 may update the integration result received from the server 200.

Alternatively, the server 200 may transmit the first monitoring result and the second monitoring result to the electricity meter 100 . In this case, the server 200 may perform a relay role of transmitting the first monitoring result and the second monitoring result to the electric meter 100 equipped with the sensing device. It is preferable that the first monitor 10 and the second monitor 20 are installed in units of the server 200 rather than the unit of the load 90. In this case, each monitor communicates with the server 200 rather than the load 90. can be formed to Accordingly, the monitoring result of each monitor is acquired by the server 200, and the server 200 may transmit the corresponding monitoring result to the electric meter 100 configured to communicate. The electric meter 100 may transmit the classified and accumulated result to the server 200 or to a separate billing means.
