Description

  The present invention relates to an improvement in an output control apparatus for an electric power device and an output control method for an electric power device that can safely guide evacuation by, for example, lighting an illumination device in an emergency such as an earthquake. It is related to preventing malfunctions by accurately determining whether the vibration is caused by an earthquake by appropriately responding to each installation location.

  For example, even when an emergency such as the occurrence of an earthquake occurs at the time of turning off at night etc. and it is necessary to evacuate urgently, because it is in a state where it is mentally restless, It may be difficult to evacuate properly after lighting the lighting fixtures. As a result, there is a risk of being unable to evacuate quickly in the dark. In particular, it may be assumed that, in nursing homes, it is not possible to provide sufficient evacuation instructions and assistance to care recipients by staff alone. . For this reason, it has been proposed to detect and generate an evacuation passage by detecting the occurrence of an earthquake at night or the like and turning on lighting devices such as living rooms, hallways, and stairs (for example, Patent Document 1). Etc.).

  However, even if there is no earthquake or the like, the building always has some kind of inherent vibration, and this inherent vibration, in particular, its location conditions, age, structure, Even in the same building, it is different depending on the number of floors such as the lower floor, the middle floor, and the higher floor. For example, in the case of a building facing a road on which a large vehicle or the like frequently passes or a building constructed near a railroad track, a large earthquake may suddenly occur due to an external factor. In addition, the inherent vibration tends to increase with age.

  For this reason, judging whether or not it is an earthquake based only on the absolute value of the magnitude of the shaking, even if it is a vibration other than an earthquake, the lighting fixtures are turned on by mistake, and the sleeper is turned on unnecessarily during the night. There is a risk of disturbing or even causing confusion. In addition, judging only by the magnitude of the shaking, for example, when an object suddenly collides with a building, and when evacuation is not necessarily required, it is determined that a sudden vibration other than an earthquake is an earthquake and a malfunction occurs. There is also a risk.

  Furthermore, some earthquakes are not only short-period earthquakes of about 4 Hz (period 0.25 seconds), but long-period earthquakes of about 1 Hz to 0.33 Hz (period 1 second to period 3 seconds). There is also a problem that it is impossible to detect either short-cycle or long-cycle earthquakes simply by detecting whether or not the earthquake is at a specific predetermined time. In particular, many of the currently available seismic sensors only deal with relatively short-period earthquakes, and it is difficult to detect long-period earthquakes. Over the years.

  On the other hand, in recent years, electric locks such as auto-locks have become widespread. As a result, in the event of an earthquake, etc., if a power failure occurs due to any cause, it is not possible to unlock and evacuate outside the building. There was also a risk of being trapped inside. Accordingly, it is desirable to unlock the necessary power outage or the like, or to ensure that necessary power equipment is operated even in the event of a power outage.

  According to the present invention, as described above, the average value of the acceleration data of the vibration within a predetermined time measured by the acceleration sensor in a steady state where no earthquake has occurred is calculated and the average value is repeatedly calculated continuously. The reference value, which is basic vibration data in the steady state, is constantly calculated using the moving average method, and the specific vibration value at the location where the acceleration sensor is installed, which varies depending on the location conditions, age, structure, floor number, etc. of the target property The reference value is compared with the real-time acceleration data measured by the acceleration sensor, and an earthquake is determined only when the difference between the real-time acceleration data and the reference value exceeds a predetermined threshold. Therefore, for example, an acceleration sensor is installed without misjudging non-earthquakes as earthquakes, such as those caused by vehicle traffic or nearby construction. It has been in correspondence with each position properly determined to be an earthquake, accurately only when necessary is practical benefits which can operate the power equipment.

  According to the present invention, as described above, when the difference between the real-time acceleration data and the reference value exceeds a predetermined threshold continuously for a predetermined time or more, it is determined as an earthquake. Although it is a relatively large impact such as a collision, there is an actual advantage that sudden and non-earthquake vibrations other than earthquakes are not erroneously determined as earthquakes.

  According to the present invention, as described above, when the real-time acceleration data exceeds a predetermined threshold for a predetermined time or more, it is determined that the earthquake has ended, and when it is determined that the earthquake has ended, the vibration occurrence determination unit Because the judgment result is reset and the verification of the reference value at the time of the earthquake and the real-time acceleration data measured by the acceleration sensor is restarted, the measurement is restarted with the vibration from the previous earthquake as the reference value. Even if the tremor is caused by an earthquake, it is possible to avoid misjudging that it is not an earthquake. For example, there is an actual benefit that can respond appropriately to earthquakes that occur continuously within a short period of time. .

  In this case, in particular, according to the present invention, as described above, when the real-time acceleration data falls below the predetermined threshold, the predetermined time until it is determined that the earthquake has ended is determined as the earthquake vibration to be detected. Since the setting can be arbitrarily changed according to the period, for example, not only a short period earthquake of about 4 Hz (period 0.25 seconds), but also by setting this predetermined time longer, for example, 1 Hz (period 1 (2) long-period earthquakes can be properly detected, and by detecting such long-period earthquakes, there is an actual benefit that can be used to diagnose damaged buildings. is there.

  According to the present invention, since the output time to the power device can be set by the timer unit as described above, the power device such as a lighting device can be appropriately operated according to the time required for evacuation. On the other hand, it is possible to cope with power saving without operating the power equipment for an unnecessarily long time.In addition, the output time to this power equipment can be set in multiple ranges according to the magnitude of the measured earthquake. There is an actual benefit that can be set and set to the output time according to the magnitude of the earthquake.

  According to the present invention, as described above, the acceleration data measured by the acceleration sensor and the reference value calculated by the reference value calculation unit are continuously stored. There is an actual benefit that can be grasped.

  According to the present invention, as described above, a fire alarm, a security sensor and other external devices can be connected and output to a power device by a relay circuit in accordance with an input from the connected external device. There is an actual advantage that it can cope with controlling necessary electric power equipment for causes such as fire and crime prevention.

  According to the present invention, as described above, since the uninterruptible power supply can be connected to the external power connection terminal, it is possible to appropriately control the power equipment even during a power failure caused by the occurrence of an earthquake or the like. There are real benefits that can be made.

  According to the present invention, as described above, since the three-dimensional acceleration sensor is used as the acceleration sensor, more accurate data can be acquired when determining the reference value that is a specific vibration value and the earthquake. There are real benefits.

  According to the present invention, as described above, any one or more of a lighting device, an electric lock, a rotating lamp, a transmitter, and a broadcasting device are connected to the relay circuit as the power device. If an earthquake occurs at night, you can evacuate smoothly by illuminating the evacuation passage. If it is an electric lock, you can open the door by unlocking it to secure the evacuation passage. There is an advantage that the evacuation can be promoted and the occurrence of the earthquake can be transmitted to the outside by the transmitter and the necessity of rescue and confirmation can be confirmed outside.

It is a schematic block diagram of the output control apparatus of the electric power equipment of this invention. It is a general | schematic flow until it determines whether it is a vibration by an earthquake from the initial setting state of the output control apparatus of the electric power equipment of this invention. It is a basic flow of the operating state of the output control apparatus of the electric power equipment of this invention. It is a flow of the process which checks generation | occurrence | production of a vibration in this invention. It is a flow of the process which checks the continuation of a vibration in this invention.

  An embodiment for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 shows an output control apparatus 10 for a power device according to the present invention. This output control apparatus 10 is, for example, an office building or an apartment. When it is installed on the corridor of a building used by many people or on the walls of each living room, etc., and it detects an earthquake above a certain level at the installation location and determines that it is an earthquake, it is transferred to a power device such as a lighting fixture (not shown) It outputs and makes these electric power devices perform a predetermined | prescribed operation | movement.

  Thus, in an emergency such as the occurrence of an earthquake, the evacuation can be safely guided, for example, by turning on a lighting device. Therefore, although there is no particular limitation on the installation location of the output control device 10, it is particularly useful when installed in a building where a care recipient who needs evacuation assistance such as a hospital or nursing home is occupying. Sexually increases.

  As shown in FIG. 1, the output control device 10 includes an acceleration sensor 12 that measures the acceleration of vibration, a central processing unit 14 to which the acceleration sensor 12 is connected, and an input / output connected to the central processing unit 14. A processing unit 16 and a relay circuit 18 connected to the input / output processing unit 16 and outputting to the connected power device are provided.

  As shown in FIG. 1, the acceleration sensor 12, the central processing unit 14, and the input / output processing unit 16 are installed on the main board 20, and the relay circuit 18 is electrically connected to the main board 20. . Further, as shown in FIG. 1, a reference value calculation unit 22, an earthquake occurrence determination unit 24, and a vibration continuation monitoring unit 26 are set in the central processing unit 14.

(1. Accelerometer)
The acceleration sensor 12 is not particularly limited, but it is desirable to use a three-dimensional acceleration sensor that detects acceleration in the three directions of front and rear, left and right, and up and down in order to measure and acquire more precise data of vibration. As this three-dimensional acceleration sensor, for example, an IC chip type sensor that has recently been used in a game machine or the like, specifically, a movable part inside the sensor and a fin installed on a non-movable part are provided. And detecting the magnitude and direction of acceleration (capacitance type three-dimensional sensor) by detecting the change in capacitance due to the change in the distance between the movable part and the fin. Can be used. By installing the output control device 10 of the present invention having the acceleration sensor 12 on a wall surface of an object, it is possible to detect a vibration at the installation location.

(2. Reference value calculation unit)
The reference value calculation unit 22 calculates the average value of the acceleration data of the vibration within a predetermined time measured in the steady state where the earthquake is not generated by the acceleration sensor 12, and calculates the average value repeatedly and continuously. A reference value, which is basic ground motion data in a steady state, is constantly calculated by the moving average method. In addition, this reference value can be used as the reference value by using the average value of the respective acceleration data for each of the three axis directions when the three-dimensional acceleration sensor 12 is used.

  Specifically, the reference value calculation unit 22 samples acceleration data measured by the acceleration sensor 12 in a steady state where no earthquake has occurred, for example, every 10 mSec (0.01 seconds), and these acceleration data The average value for about 10 seconds is calculated. Therefore, this average value is updated every 10 mSec, and the latest average value in the latest 10 seconds is constantly calculated. The latest average value in the latest 10 seconds is set as a reference value, assuming that it is a specific vibration value (basic vibration data) at the installation location.

  This standard value is, for example, 1) a building facing a road where large vehicles etc. frequently pass, a building constructed near the railroad track, etc. Location of the target property, such as the property being operated, 2) Depending on the structure of the target property such as reinforced concrete, lightweight steel, wooden, etc. Even if the same target property, 4) lower floor, middle floor It also changes depending on the number of floors such as higher floors. Furthermore, 5) It changes over time depending on the age after construction. Therefore, by calculating this reference value, it is possible to determine whether or not it is an earthquake appropriately according to the installation location. Especially, since the reference value is always calculated as the most recent data, It is possible to appropriately cope with changes in intrinsic vibration values due to deterioration.

(3. Earthquake occurrence determination part)
The earthquake occurrence determination unit 24 collates the reference value calculated by the reference value calculation unit 22 with the real-time acceleration data measured by the acceleration sensor 12, and the difference between the real-time acceleration data and the reference value is predetermined. If the threshold value is exceeded, it is determined that the earthquake is occurring. In other words, the earthquake occurrence determination unit 24 does not simply determine whether an earthquake is based on the absolute value of the magnitude of vibration (swing), but rather is a reference that is a unique vibration value that is different for each installation location. From the value, it is possible to judge how much the vibration was.

  For this reason, for example, when a large vehicle frequently passes or when construction work is performed in the neighborhood although it is limited in time, even if the intrinsic vibration value (reference value) is relatively large, It is determined that it is an appropriate earthquake corresponding to each location where the acceleration sensor 12 is installed, without misjudging the non-earthquake such as those caused by the traffic of these vehicles and nearby construction. Power equipment can be activated accurately only when necessary

  Specifically, as illustrated in FIG. 4, the earthquake occurrence determination unit 24 combines the difference between the real-time acceleration data in the three-axis direction measured by the three-dimensional acceleration sensor 12 and the reference value in the three-axis direction. And the composite value is compared with a preset threshold value. If the composite value exceeds the threshold value, it is determined that there is a possibility of an earthquake, and the vibration occurrence flag is turned on. On the other hand, when the composite value does not exceed the threshold value, the collation between the real-time acceleration data and the reference value is continued.

  In addition, the magnitude | size of this threshold value can be set in steps suitably as needed, and the value can also be changed after setting. As a result, for example, when there is a relatively large danger, for example, an earthquake with a vibration of 2 or less, the output control to the power equipment is avoided without daringly judging the earthquake, and an earthquake with a seismic intensity of 3 or more is avoided. Only in some cases can the power equipment be activated.

  The earthquake occurrence determination unit 24 determines that the earthquake is an earthquake when the difference between the real-time acceleration data and the reference value exceeds a predetermined threshold continuously for a predetermined time or more. For this reason, for example, although it is a relatively large impact such as a collision of an object, it is possible to avoid accidental determination of sudden or single vibration other than an earthquake as an earthquake.

  In this case, specifically, when the earthquake occurrence flag is turned on as described above, the earthquake occurrence determination unit 24 performs a warning determination on a predetermined warning determination time set in advance as shown in FIG. Enter the timer to start the countdown, and when the warning judgment timer reaches “0” without the end of the vibration until the warning judgment time elapses, it is judged that the earthquake is an earthquake, and the warning mode is entered. And the output control to the electric power device through the relay circuit 18 is performed. In addition, this warning determination time can be arbitrarily set at the time of initial setting within a range suitable for determining that the vibration is caused by an earthquake such as 0.5 seconds to 2.3 seconds.

  In this case, as shown in FIG. 5, the warning determination timer counts down and decrements every 10 mSec, which is the same as the reference value sampling, and the earthquake occurrence determination unit 24 causes the warning determination time to elapse. Until the value becomes “0”, the comparison of the composite value of the difference and the threshold is repeated every 10 mSec, and it is determined that the vibration has ended by the vibration continuation monitoring unit 26 described later until the set warning determination time elapses. Except when it is not performed (that is, when the vibration continues), the vibration generation flag is kept on, and output control to the power device is performed as a warning mode.

(4. Ground motion monitoring section)
The seismic continuation monitoring unit 26 determines that the earthquake has ended when the real-time acceleration data falls below a predetermined threshold for a predetermined time or more after the earthquake occurrence determination unit 24 determines that the event is an earthquake. Specifically, the vibration continuation monitoring unit 26, when the earthquake occurrence determination unit 24 turns on the vibration occurrence flag, is preset as shown in FIG. 4, for example, 200 mSec (0.2 seconds) As shown in FIG. 5, the estimated duration of vibration is input to the vibration duration timer, and as shown in FIG. 5, the difference between the real-time acceleration data and the reference value in the three-axis direction before the vibration duration timer becomes “0”. If the composite value falls below the threshold value, the real-time acceleration data and the reference value are repeatedly checked until the vibration duration timer reaches “0”. If the composite value exceeds the threshold value, the vibration duration timer is set again. Enter 200mSec and monitor if the vibration continues. The seismic duration monitoring unit 26 determines that the seismic duration timer has become “0” as a result of the combined value falling below the threshold during the set expected seismic duration of 200 mSec (0.2 seconds) and 200 mSec has elapsed. As shown in FIG. 5, it is determined that the earthquake has ended, and the vibration occurrence flag is turned off.

  In this way, when the vibration continuation monitoring unit 26 determines that the earthquake has ended and turns off the vibration generation flag, the earthquake occurrence determination unit 24 resets the determination result, and when the earthquake occurs (the vibration generation flag is set). The collation of the reference value at the time of turning on) and the real-time acceleration data measured by the acceleration sensor 12 is resumed.

  In this case, when resuming collation (earthquake occurrence check), calculating the reference value based on the reference value at the time of the earthquake, not the average value immediately before the end of the earthquake, but comparing with the reference value The reason for restarting is to avoid including the abnormal vibration value due to the earthquake in the reference value which is the vibration value unique to the installation location. As a result, measurement can be resumed using the vibration from the previous earthquake as a reference value, and it is possible to avoid misjudging that it is not an earthquake even if it is a large shake due to an earthquake. Can respond appropriately to earthquakes.

  In addition, the vibration continuation monitoring unit 26 arbitrarily changes the setting of a predetermined time (predicted vibration duration of 200 mSec or the like) until it is determined that the earthquake has ended when the real-time acceleration data falls below a predetermined threshold. it can. Specifically, it can be set according to the period of the earthquake vibration to be detected, and this estimated vibration duration (t) can be expressed as f = 1 / t when converted to the frequency (f). Therefore, for example, if it is 200 mSec (0.2 seconds), an earthquake of f = 1 / 0.2 seconds = 5 Hz can be detected. Therefore, similarly, for example, when set to 250 mSec (0.25 seconds), an earthquake having a short period of about 4 Hz (period 0.25 seconds) can be reliably detected, while 1000 mSec (1 second). If a relatively long period is set, an earthquake with a longer period of about 1 Hz (period 1 second) can be appropriately detected.

  This is particularly beneficial in that it can cope with long-period earthquakes that are difficult to detect with current seismic sensors. In addition, if long-period vibrations can be detected in this way, it can be used for diagnosis of damaged buildings. In this case, by setting a circuit such as a plurality of vibration duration timers in a single output control device 10, or by setting a plurality of output control devices 10, a plurality of assumed vibration durations are set, It can also be set up to handle both short-cycle and long-cycle earthquakes.

(5. Relay circuit)
As shown in FIG. 5, the relay circuit 18 is connected via the output terminal 28 shown in FIG. 1 when the vibration continues for the warning determination time and the earthquake occurrence determination unit 24 shifts to the warning mode. Output to external power equipment not to perform necessary control. In this case, as shown in FIG. 1, the output control device 10 preferably includes a timer unit 30 that sets an output time to the power device in the central processing unit 14. The timer unit 30 sets, for example, how long the output to the power device is continued. For example, the timer unit 30 is set in stages such as 30 minutes, 60 minutes, 90 minutes, and 120 minutes. In the initial setting stage after the output control device 10 is installed, it can be set at any time as required by selecting a dip switch on the main board 20 or the like.

  As a result, it is possible to properly operate power devices such as lighting fixtures according to the time required for evacuation, etc., while also being able to respond to power saving without operating power devices for longer than necessary, Furthermore, the output time to the power device can be set to a plurality of ranges according to the measured magnitude of the earthquake, and set to the output time according to the magnitude of the earthquake.

(6. Electric power equipment)
Moreover, as an external electric power apparatus connected to the relay circuit 18 via the output terminal 28, although there is no limitation, a lighting fixture can be mentioned, for example. When connected to a luminaire, it is possible to smoothly determine the evacuation passage by illuminating the corridor and each room when an emergency such as the occurrence of an earthquake occurs even when the lights are turned off at night.

  An electric lock can also be connected as a power device. When an electric lock is connected, when an emergency occurs, the electric lock can be unlocked to open the door, and the door can be opened manually to ensure an evacuation passage. In addition, by connecting a rotating light, siren, and broadcaster to evacuate visually and audibly, and by connecting a transmitter, the transmitter can transmit the occurrence of an earthquake to the outside for rescue. And the necessity of confirmation can be confirmed externally. The output control device 10 includes a plurality of output terminals 28, and any one of these power devices can be used alone, or a plurality of them can be used simultaneously.

(7. Input terminal)
On the other hand, as shown in FIG. 1, the output control apparatus 10 of the present invention further includes an input terminal 32 for a fire alarm, a security sensor and other external devices. The signal input from the input terminal 32 is processed in the central processing unit 14 via the input / output processing unit 16, and when there is an input from an external device, as in the case of the occurrence of an earthquake, the input is performed. Accordingly, the relay circuit 18 is set so that it can output to the power device.

  Therefore, the output control device 10 of the present invention is not limited to earthquakes, for example, in response to a fire when a fire alarm is connected, or to an intrusion of a suspicious person when a security sensor is connected, It can be output to lighting equipment, sirens and other necessary power equipment and applied as a fire prevention system and crime prevention system.

(8. External power supply connection terminal)
In addition, the output control device 10 of the present invention also includes an external power supply connection terminal 34 as shown in FIG. As shown in FIG. 1, the output control device 10 has a unique power supply unit. However, an uninterruptible power supply device (not shown) is connected to the external power supply connection terminal 34 to cause an earthquake or the like. Even during a power outage, the power equipment can be appropriately controlled to evacuate smoothly.

(9. Data storage unit)
Furthermore, as shown in FIG. 1, the output control apparatus 10 of the present invention also includes a data storage unit 36 that continuously stores acceleration data measured by the acceleration sensor 12 and a reference value calculated by the reference value calculation unit 22. ing. The data storage unit 36 can use a flexible storage medium such as a memory card. By including a reference value within a certain period as data to be stored in the data storage unit 36, for example, a change in the reference value over time can be accurately grasped. In addition, average values and maximum values within a predetermined time of acceleration data measured by the acceleration sensor 12 can be stored.

(10. Control method)
Next, an output control method for a power device using the output control apparatus 10 will be described with reference to FIGS. First, the steps from the installation of the output control device 10 to the start of operation will be described with reference to FIG. 2. After the output control device 10 is installed at the target installation location, the reference value is calculated first. Measure and record the basic vibration data (specific vibration value) at the installation location, and use the basic vibration data as a reference value to make various necessary settings such as threshold values and warning judgment time. After that, as the vibration occurrence check process, the real-time data is compared with the reference value, and if there is a possibility of an earthquake and the vibration occurrence flag is turned on, the vibration continuation check process is performed.

  In this case, first, as a basic process in a steady state, as shown in FIG. 3, the reference value calculation unit 22 repeatedly calculates a reference value every 10 mSec from acceleration data measured by the acceleration sensor 12, and the reference value is calculated. This calculation process is performed until the amount of past data necessary for calculation is accumulated. In this case, as described above, when the reference value is calculated from the average value of the acceleration data sampled every 10 mSec (0.01 seconds) for about 10 seconds, first, the data for 10 seconds for every 10 mSec. Considering the number of data, that is, 1000 pieces of data, and the time lag of the processing time of each unit, as shown in FIG. 3, the calculation process is performed until 1024 pieces of data are accumulated, and these necessary data are obtained. After the number is accumulated, the subsequent processing is started. At the time of initial setting, measurement is performed for about 30 seconds, necessary acceleration data is sampled, and a reference value is calculated. When necessary past data is accumulated and the reference value for each installation location can be calculated, the reference value is calculated repeatedly, and the latest reference value is continuously calculated. A check process is performed.

  In the vibration check process for determining whether the vibration is an earthquake or not, as shown in FIG. 4, the reference value calculation unit 22 calculates the average value by dividing the past data of the acceleration data by the number of past data. As the reference value, the earthquake occurrence determination unit 24 collates the real-time data in the three-axis direction measured by the acceleration sensor 12 with the reference value in the three-axis direction, and always calculates the difference. In this case, when the earthquake occurrence flag is not turned on and an earthquake is not detected, the earthquake occurrence determination unit 24 calculates a composite value of this difference as shown in FIG. The composite value is checked against a preset threshold value to determine whether the composite value exceeds the threshold value.

  If the composite value of the difference does not exceed the threshold value, the real-time acceleration data is continuously checked against the reference value, and the occurrence of vibration is continuously checked. On the other hand, if the composite value of the difference exceeds the threshold, it is determined that there is a possibility of an earthquake, and the vibration occurrence flag is turned on, and in response to this, as shown in FIG. 4 and FIG. The predetermined warning determination time is input to the warning determination timer, and the countdown of the warning determination time is started in order to finally determine whether or not it is an earthquake. At the same time, in the vibration continuation monitoring unit 26, in order to determine whether or not the earthquake has ended, the estimated vibration duration is input to the vibration duration timer, and the state where the combined value of the differences exceeds the threshold continues for 200 mSec. To monitor. If the combined value of the differences already exceeds the threshold value and the vibration occurrence flag is turned on, the vibration continuation check process shown in FIG. 5 is continued as shown in FIG.

  When the vibration occurrence flag is turned on and the process proceeds to the vibration continuation check process, in this vibration continuation check process, as shown in FIG. 5, the input warning determination time has elapsed and the warning determination timer becomes “0”. The difference composite value is compared with the threshold, and the difference composite value is, for example, until the warning judgment time set in the range of 500 mSec (0.5 seconds) to 2300 mSec (2.3 seconds) elapses. In the meantime, if the value falls below the threshold value, the estimated vibration duration of 200 mSec input to the vibration duration timer is decremented by 10 mSec, and the set estimated vibration duration is 200 mSec (0.2 seconds). As shown in FIG. 5, when the vibration duration timer becomes “0” as a result of the combined value falling below the threshold value and 200 mSec has elapsed, the earthquake has ended. And disconnection, the vibration occurrence flag is turned off, returns to the vibration generating check process shown in FIG. On the other hand, if the composite value of the difference has not yet fallen below the threshold and the composite value of the difference has exceeded the threshold while the warning determination time input to the warning determination timer has elapsed, 200 mSec is again set to the vibration duration timer. Enter and monitor whether the vibration continues.

  On the other hand, as shown in FIG. 5, the earthquake occurrence determination unit 24 determines that the earthquake is an earthquake only when the warning determination timer becomes “0” without the end of the vibration until the warning determination time elapses. Then, it shifts to a warning mode, performs output control to the power device through the relay circuit 18, and causes the power device to perform a predetermined operation for a predetermined time set by the timer unit. It should be noted that after the time set by the timer elapses or by manual operation of the operator, resetting to return to the state at the time of occurrence of vibration can be performed again and the vibration occurrence check process can be restarted.

  The present invention is particularly suitable for assisting smooth evacuation by installing it in a building where a care recipient who needs evacuation assistance such as a nursing home or hospital is occupying, as well as office buildings and apartments. It can be widely applied to a corridor of a building used by a large number of people or the wall surface of each living room.
