FIG. 4 is a block diagram of a seismic isolation system according to a second modification of the embodiment of the present invention.

(1) Outline The outline of the seismic isolation system according to the present embodiment will be described below.

The seismic isolation system according to the present embodiment is a system for detecting an earthquake and interrupting an electric circuit, and is used for a distribution board installed in a building such as a detached house, for example.

For example, in the case of a single-phase three-wire distribution system, the distribution board 8 has a first voltage line (L1) 31, a second voltage line (L2) 32, and a neutral line (N), as shown in FIG. It is electrically connected to the power line 3 having 33. Then, the distribution board 8 distributes the AC power from the power line 3 to the plurality of branch circuits 7 via the main breaker 1.

In FIG. 1, among the plurality of branch circuits 7, the branch circuit 7 on the upper side with respect to the three conductive bars 41 to 43 is connected to the first voltage line 31 and the neutral line 33 via the two conductive bars 41 and 43. It is electrically connected. Further, among the plurality of branch circuits 7, the branch circuit 7 on the lower side with respect to the three conductive bars 41 to 43 is electrically connected to the second voltage line 32 and the neutral line 33 via the two conductive bars 42 and 43. Is connected.

In the present embodiment, each of the plurality of branch circuits 7 has a branch breaker 2, a load 5, and feeder lines 61 and 62 for electrically connecting the branch breaker 2 and the load 5. The load 5 is either an electric device (lighting appliance, cooking appliance, etc.) or a wiring appliance (outlet, wall switch, etc.).

By the way, in a situation where an aftershock occurs after the main shock, the houses (buildings), furniture, etc. are damaged by the main shock, so even if it is an aftershock, there is a high risk and it may be better to shut off the electric circuit. However, in the conventional seismic isolation system, the threshold value for determining whether or not to interrupt the electric circuit is constant, and in many cases, the threshold value is not exceeded by the seismic motion of an aftershock, and even in a situation where the electric circuit should be interrupted. There was a possibility that the electric circuit could not be cut off.

The seismic isolation system according to the present embodiment is configured as follows so that the electric circuit can be interrupted even if the aftershock of the seismic motion smaller than the main shock.

As shown in FIG. 1, the seismic isolation system 10 according to the present embodiment includes a vibration detection unit 11, a storage unit 12, a determination unit 13, and a blocking unit 14. The vibration detection unit 11 detects the magnitude of the seismic motion. The storage unit 12 stores historical information about seismic motion based on the detection result of the vibration detection unit 11. The determination unit 13 performs a determination process for determining whether or not to cut off the electric circuit based on the magnitude of the seismic motion detected by the vibration detection unit 11. The blocking unit 14 cuts off the electric path according to the determination result of the determination unit 13. The determination unit 13 is configured to change the sensitivity of the determination process based on the history information stored in the storage unit 12. The "sensitivity of the determination process" here is the sensitivity when the determination unit 13 determines that the electric circuit is cut off.

According to this configuration, the sensitivity of the determination process is changed based on the history information stored in the storage unit 12. Therefore, by increasing the sensitivity after the vibration detection unit 11 detects the main shock, the seismic motion smaller than the main shock Even if it is an aftershock, the electric circuit can be cut off. In other words, the safety can be improved as compared with the case where the sensitivity of the determination process is constant.

(2) Details Hereinafter, details of the seismic isolation system 10 according to the present embodiment will be described with reference to FIG.

As shown in FIG. 1, the seismic isolation system 10 according to the present embodiment is used for the distribution board 8 installed in the building 100, and the electric circuit in the distribution board 8 is used according to the magnitude of the detected ground motion. To shut off. The building 100 is, for example, a detached house.

(2.1) Configuration As shown in FIG. 1, the seismic isolation system 10 according to the present embodiment includes a vibration detection unit 11, a storage unit 12, a determination unit 13, and a blocking unit 14. Further, the seismic isolation system 10 further includes a calculation unit 15 and a contact unit 16.

In the present embodiment, the seismic circuit breaker 10 is a main circuit breaker 1 for opening and closing electric circuits from a system power supply (for example, a commercial power supply) to a plurality of branch circuits 7, and the main circuit breaker 1 is a so-called seismic circuit breaker. (Hereinafter, also referred to as "seismic breaker 1"). Therefore, the electric circuit referred to here is a power line 3 and three conductive bars 41 to 43 that electrically connect the system power supply and the plurality of branch circuits 7.

The vibration detection unit 11 is, for example, a seismic sensor using a 3-axis acceleration sensor, detects the magnitude of seismic motion, and outputs the detection result to the calculation unit 15. The calculation unit 15 obtains the duration of the ground motion and the frequency (number of times) of the ground motion in a certain period (for example, one week, etc.) based on the detection result of the vibration detection unit 11, and determines the magnitude of the ground motion and the duration of the ground motion. And the frequency of seismic motion is stored in the storage unit 12.

The storage unit 12 is a memory in which data can be rewritten, and is particularly preferably a non-volatile memory. The storage unit 12 stores at least the magnitude of the ground motion, the duration of the ground motion, and the frequency of the ground motion in a certain period as historical information about the ground motion. In the present embodiment, the storage unit 12 has a capacity capable of storing history information of, for example, about one month. Therefore, the storage unit 12 is configured to delete the historical information that is oldest in time in order.

The determination unit 13 and the calculation unit 15 are composed of a microprocessor and a microcomputer having a memory. That is, the determination unit 13 and the calculation unit 15 are realized by a computer system having a processor and a memory. Then, when the processor executes an appropriate program, the computer system functions as the determination unit 13 and the calculation unit 15. The program may be pre-recorded in a memory, may be recorded through a telecommunication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card. Further, the program may be pre-recorded in the storage unit 12.

The determination unit 13 performs a determination process for determining whether or not to cut off the electric circuit based on the magnitude of the seismic motion detected by the vibration detection unit 11. In the determination process, the determination unit 13 determines that the electric path should be cut off if the magnitude of the seismic motion detected by the vibration detection unit 11 is equal to or greater than the threshold value, and blocks the electric path if the magnitude of the seismic motion is smaller than the threshold value. Judge that it should not be done. In other words, in the determination process, the determination unit 13 determines whether or not to shut off the electric circuit according to the magnitude relationship between the magnitude of the earthquake motion and the threshold value. Then, when the determination unit 13 determines in the determination process that the electric circuit should be cut off, the determination unit 13 outputs a cutoff signal for cutting off the electric circuit to the cutoff unit 14.

Further, the determination unit 13 is configured to change the threshold value for comparison with the magnitude of the seismic motion detected by the vibration detection unit 11 in the determination process based on the history information stored in the storage unit 12. There is. In other words, the determination unit 13 is configured to change the sensitivity of the determination process (hereinafter, referred to as "sensitivity") based on the history information stored in the storage unit 12. Here, as for the relationship between the threshold value and the sensitivity, the sensitivity decreases as the threshold value increases, and the sensitivity increases as the threshold value decreases. That is, when the sensitivity is increased, the threshold value is decreased, and when the sensitivity is decreased, the threshold value is increased.

For example, if the magnitude of the seismic motion stored in the storage unit 12 as history information is equal to or larger than the threshold value, the determination unit 13 increases the sensitivity by reducing the threshold value. On the other hand, the determination unit 13 lowers the sensitivity by increasing the threshold value when no earthquake has occurred in a certain period of time from the history information stored in the storage unit 12. The details will be described in detail in the column of "(3) Sensitivity change processing of the determination unit".

As described above, the calculation unit 15 obtains the duration of the ground motion and the frequency (number of times) of the ground motion in a certain period based on the detection result of the vibration detection unit 11. Then, the calculation unit 15 stores the magnitude of the ground motion, the duration of the ground motion, and the frequency of the ground motion in a certain period in the storage unit 12 as the history information of the ground motion. Further, the calculation unit 15 has a function of calculating the vibration energy E1 (see FIG. 3) due to the seismic motion based on the magnitude of the seismic motion detected by the vibration detection unit 11. The calculation unit 15 calculates the vibration energy E1 based on, for example, the magnitude of the seismic motion and the duration of the seismic motion, and stores the calculation result in the storage unit 12. The vibration energy E1 may or may not be included in the history information. Further, the calculation unit 15 may or may not calculate the vibration energy E1.

The contact portion 16 is inserted between the first voltage line 31 and the conductive bar 41, between the second voltage line 32 and the conductive bar 42, and between the neutral wire 33 and the conductive bar 43, respectively. It has contacts and is configured to open three contacts by an open signal from the blocking section 14. Further, the contact portion 16 is configured so that three contacts can be opened and closed by operating a handle provided on the front surface side of the housing of the main breaker 1.

The cutoff unit 14 generates an open signal that opens the contact unit 16 in response to the cutoff signal output from the determination unit 13, and outputs the generated open signal to the contact unit 16. In other words, the blocking unit 14 has a function of blocking the electric circuit according to the determination result of the determination unit 13.

In the present embodiment, the vibration detection unit 11, the storage unit 12, the determination unit 13, the circuit breaker 14, the calculation unit 15, and the contact unit 16 are housed in the housing 20 of the main breaker 1 as shown in FIG. There is. In other words, the seismic isolation system 10 is housed in the housing 20.

The operating power supply of the vibration detection unit 11, the storage unit 12, the determination unit 13, the circuit breaker 14, and the calculation unit 15 may be supplied from the primary side of the main breaker 1, or the main breaker 1 may be supplied. It may be supplied from the secondary side of.

(2.2) Distribution board Next, the configuration of the distribution board 8 will be described.

As shown in FIG. 1, the distribution board 8 has a main breaker (seismic breaker) 1 electrically connected to the power line 3 and a plurality of branches electrically connected to the secondary terminal of the main breaker 1. A breaker 2 and a breaker 2 are provided in the cabinet 80. In other words, the distribution board 8 includes a seismic circuit breaker system 10 (seismic circuit breaker 1) and a cabinet 80 for accommodating the seismic circuit breaker system 10.

The primary terminal of the main breaker 1 is electrically connected to a system power supply (for example, a commercial power supply) via a three-wire type (first voltage line 31, second voltage line 32, and neutral line 33) power line 3. It is connected. Three conductive bars 41 to 43 are connected to the secondary terminal of the main circuit breaker 1. The conductive bar 41 is electrically connected to the first voltage line (L1) 31, the conductive bar 42 is electrically connected to the second voltage line (L2) 32, and the conductive bar 43 is electrically connected to the neutral wire (N) 33. It is electrically connected.

Of the plurality of branch breakers 2, the branch breakers 2 above the three conductive bars 41 to 43 (hereinafter, also referred to as “first group branch breakers 2”) are the conductive bars 41 of L1 and the conductive bars 43 of N. It is electrically connected to. Further, among the plurality of branch breakers 2, the branch breakers 2 below the three conductive bars 41 to 43 (hereinafter, also referred to as “second group branch breakers 2”) are the conductive bars 42 and N of L2. It is electrically connected to the conductive bar 43. As a result, the branch breaker 2 of the first group is electrically connected to the first voltage line (L1) 31 and the neutral line (N) 33, and the branch breaker 2 of the second group is the second voltage line ( It is electrically connected to L2) 32 and the neutral wire (N) 33.

A load 5 is electrically connected to each of the plurality of branch breakers 2 via feed lines 61 and 62. FIG. 1 illustrates a case where one load 5 is electrically connected to each branch breaker 2, but two or more loads 5 may be electrically connected to each branch breaker 2. .. Each of the plurality of branch breakers 2 constitutes a branch circuit 7 together with the load 5. In other words, each of the plurality of branch circuits 7 has a branch breaker 2 and at least one load 5 electrically connected to the branch breaker 2 and supplied with power via the branch breaker 2. .. The load 5 is either an electric device (lighting appliance, cooking appliance, etc.) or a wiring appliance (outlet, wall switch, etc.).

(3) Sensitivity change process of the determination unit Next, the sensitivity change process in which the determination unit 13 changes the sensitivity (threshold value) of the determination process will be described with reference to FIG. In the following, a case where the sensitivity (threshold value) is changed based on the magnitude of the seismic motion included in the history information will be described as an example.

The determination unit 13 acquires the history information about the earthquake motion from the storage unit 12 (step S1). The determination unit 13 determines whether or not an earthquake has occurred in a certain period (for example, one week or the like) from the history information acquired from the storage unit 12 (step S2). When an earthquake occurs in a certain period (Yes in step S2), the determination unit 13 compares the magnitude (seismic intensity) of the seismic motion caused by this earthquake with the threshold value (for example, seismic intensity 5) (step S3). Then, if the magnitude of the seismic motion is equal to or greater than the threshold value (Yes in step S3), the determination unit 13 lowers the threshold value from, for example, seismic intensity 5 to seismic intensity 4 in preparation for an aftershock or the like that may occur in the future. In other words, if the magnitude of the seismic motion is equal to or greater than the threshold value, the determination unit 13 increases the sensitivity of the determination process (step S4). Further, if the magnitude of the earthquake motion is smaller than the threshold value (No in step S3), the determination unit 13 does not change the threshold value. In other words, the determination unit 13 maintains the sensitivity if the magnitude of the ground motion is smaller than the threshold value (step S5). Here, the determination unit 13 raises the sensitivity when a plurality of earthquakes have occurred in a certain period and if even one earthquake having a magnitude of seismic motion equal to or greater than the threshold value has occurred.

On the other hand, the determination unit 13 raises the threshold value from the history information acquired from the storage unit 12 if no earthquake has occurred in a certain period (No in step S2). In other words, the determination unit 13 lowers the sensitivity if no earthquake has occurred in a certain period of time (step S6). For example, if the current threshold value is seismic intensity 4, the determination unit 13 changes (raises) the threshold value from seismic intensity 4 to seismic intensity 5.

As described above, according to the seismic circuit breaker system 10 (seismic breaker 1) according to the present embodiment, the sensitivity of the determination process is based on the history information (here, the magnitude of the seismic motion) stored in the storage unit 12. Can be changed. Therefore, for example, by increasing the sensitivity (lowering the threshold value) after the main shock occurs, the electric circuit can be cut off even if the aftershock has a smaller seismic motion than the main shock. In other words, according to the seismic circuit breaker system 10 (seismic breaker 1) according to the present embodiment, the safety can be improved as compared with the case where the sensitivity of the determination process is constant.

Further, according to the seismic circuit breaker system 10 (seismic breaker 1) according to the present embodiment, the sensitivity of the determination process is lowered when an earthquake does not occur in a certain period (for example, one week or the like). (Increasing the threshold). In other words, the determination unit 13 is configured to return (decrease) the sensitivity to the state before the change when the predetermined condition is satisfied. This has the advantage that the electric circuit is less likely to be cut off by an earthquake with a small ground motion. Here, the state before the change may be a state immediately before the sensitivity at the present time, or may be an initial state (for example, a state at the time of shipment from the factory).

Further, for example, in a situation where an aftershock continues after a main shock, the electric circuit is cut off each time an aftershock occurs, which may reduce convenience. Therefore, it is preferable that the determination unit 13 is configured to reduce the increase in sensitivity or maintain the sensitivity in a situation where an aftershock continues after the main shock. As a result, in a situation where aftershocks follow the main shock, it is possible to improve convenience while improving safety.

(4) Modified Example The above-described embodiment is only one of various embodiments of the present invention. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present invention can be achieved. Hereinafter, modifications of the above-described embodiment will be listed. The modifications described below can be applied in combination as appropriate.

(4.1) First Modified Example The operation of the seismic isolation system 10 according to the first modified example will be described with reference to FIG. In the above-described embodiment, the determination unit 13 is configured to change the sensitivity (threshold value) of the determination process according to the magnitude of the seismic motion generated in a certain period. On the other hand, in the first modification, the determination unit 13 is configured to change the sensitivity according to the integrated value of the vibration energy E1 calculated by the calculation unit 15. Hereinafter, the sensitivity change process of the determination unit 13 according to the first modification will be specifically described with reference to FIG.

FIG. 3 is a graph showing the integrated value of the vibration energy E1 due to three earthquakes generated in a predetermined period T1 (for example, one week or the like). Eth in FIG. 3 is a comparison value for comparison with the integrated value of the vibration energy E1 due to the seismic motion, and the determination unit 13 determines the sensitivity according to the magnitude relationship between the comparison value Eth and the integrated value of the vibration energy E1. It is configured to change.

The vibration energy E1 due to the first earthquake in the predetermined period T1 is E11, which is smaller than the comparative value Eth. Therefore, the determination unit 13 does not change the sensitivity (threshold value) after the first earthquake. The integrated value of the vibration energy E1 due to the two earthquakes in the predetermined period T1 is E12, which is also smaller than the comparative value Eth. Therefore, the determination unit 13 does not change the sensitivity (threshold value) even after the second earthquake. The integrated value of the vibration energy E1 due to the three earthquakes in the predetermined period T1 is E13, which is larger than the comparative value Eth. Therefore, the determination unit 13 increases the sensitivity (lowers the threshold value) in preparation for aftershocks and the like that may occur after the third earthquake after the third earthquake.

As described above, according to the seismic isolation system 10 of the first modification, the sensitivity is changed according to the integrated value of the vibration energy E1 in the predetermined period T1, so that the seismic motion smaller than the main shock is similar to the above-described embodiment. Even if it is an aftershock, the electric circuit can be cut off. In other words, according to the seismic isolation system 10 of the first modification, the safety can be improved as compared with the case where the sensitivity of the determination process is constant. Further, since the damage to the building 100 or the like depends on the magnitude of the vibration energy E1 due to the earthquake motion, the sensitivity can be changed more accurately than the case where the sensitivity is changed according to the magnitude of the earthquake motion or the like. ..

(4.2) Second Modified Example The seismic isolation system 10 according to the second modified example will be described with reference to FIG. In the above-described embodiment and the first modification, the case where the seismic circuit breaker 1 is used as an example has been described, but the seismic circuit breaker system 10 may be a seismic outlet 9. For example, as shown in FIG. 4, when the seismic outlet 9 is electrically connected to any of the branch breakers 2 among the plurality of branch breakers 2, the branch breaker 2 is connected to the branch breaker 2 via the seismic outlet 9. Only the electric circuit to the electrically connected electric device can be cut off. Hereinafter, the seismic isolation system 10 (seismic outlet 9) of the second modification will be specifically described with reference to FIG.

As shown in FIG. 4, the seismic outlet 9 includes a vibration detection unit 91, a storage unit 92, a determination unit 93, a blocking unit 94, a calculation unit 95, and a contact unit 96. The vibration detection unit 91, the storage unit 92, the determination unit 93, the cutoff unit 94, the calculation unit 95, and the contact unit 96 are the vibration detection unit 11, the storage unit 12, and the determination unit 13, respectively, described in the above-described embodiment. , The same applies to the blocking unit 14, the calculation unit 15, and the contact 16, and detailed description thereof will be omitted here. In the second modification, the vibration detection unit 91, the storage unit 92, the determination unit 93, the blocking unit 94, the calculation unit 95, and the contact unit 96 are housed in the housing 90 of the seismic outlet 9 as shown in FIG. Has been done. In other words, the seismic isolation system 10 is housed in the housing 90.

In the example shown in FIG. 4, a plurality of loads 5 (two in the illustrated example) are electrically connected to the branch breaker 2 in parallel with the seismic outlet 9. In this case, even if the seismic outlet 9 functions due to an earthquake, the electric circuit to the plurality of loads 5 is not cut off, and the electric circuit to the electric device electrically connected to the branch breaker 2 via the seismic outlet 9 is not cut off. Only will be blocked. Therefore, in this case, for electric devices such as refrigerators and lighting fixtures whose power supply should be secured even after the earthquake, the electric devices such as the load 5 can be directly connected to the branch breaker 2 after the earthquake. Can be continuously operated even in.

(4.3) Other Modification Examples The other modification examples are listed below.

For example, as shown in FIG. 1, when the seismic isolation system 10 includes a person detection unit 17 for detecting the presence or absence of a person in the building 100, the determination unit 13 determines the detection result of the person detection unit 17. The sensitivity (threshold value) of the determination process may be changed according to the above. The human detection unit 17 is, for example, a motion sensor using infrared rays, ultrasonic waves, visible light, or the like. In a situation where a person is not detected by the person detection unit 17, the determination unit 13 does not reduce the convenience even if the electric circuit is cut off. Therefore, it is preferable to increase the sensitivity (lower the threshold value) in consideration of safety. Further, in the situation where a person is detected by the person detection unit 17, the determination unit 13 reduces the increase in sensitivity or maintains the sensitivity so that the convenience can be improved while improving the safety. It is preferable to do so. According to this configuration, the sensitivity can be adjusted according to the presence or absence (home status) of a person in the building 100.

Further, the person detection unit 17 not only directly detects the presence or absence of a person like a motion sensor, but also, for example, when a HEMS (Home Energy Management System) is connected to the distribution board 8. , It may be configured to acquire the existence / absence information of a person from HEMS. In HEMS, the amount of power consumed (used) in the building 100 is measured, and the presence or absence of a person in the building 100 can be determined from this amount of power consumed.
