Description

  The present invention relates to a device control method based on an earthquake early warning, and more particularly, to a method for determining and executing a control that requires control such as shutdown based on an earthquake early warning before arrival of earthquake motion. Is. The present invention also relates to a system capable of executing such a device control method, computer software for causing the system to execute the method, and a storage medium storing the software.

In the event of an earthquake, there is a concept of protecting important devices by taking measures before the seismic wave arrives, and for this reason, the Japan Meteorological Agency sends emergency earthquake bulletins immediately after the earthquake occurs .
An attempt to protect a device or human life by using the earthquake early warning is described in Japanese Patent Application Laid-Open No. 2008-63066. The invention described in this publication calculates an allowance time from the time of receiving an earthquake early warning to the arrival of an earthquake wave, and moves to a safer floor with higher priority according to the allowance time. It is related with the control operation device at the time of earthquake. The system of the present invention comprises an elevator controller for controlling the operation of the elevator and an earthquake information receiving means for receiving an emergency earthquake warning, and when the earthquake information receiving means receives the emergency earthquake warning, the earthquake wave is received from the reception of the earthquake early warning. Calculate the surplus time until it arrives, determine the evacuation floor from the surplus time and the travel time to each evacuation floor based on the priority order of the evacuation floor set in advance according to the building specifications, and prioritize Control operation to a higher and safer floor.

  The above invention is an elevator control method based on the determination of at which floor the elevator should be stopped before the arrival of the seismic wave, but is not related to the control of a plurality of different types of control objects, but before the arrival of the earthquake motion. In order to perform appropriate control for a plurality of control target devices, there is no technical idea for performing management by assigning priorities to different types of control target devices according to events.

  Japanese Patent Application Laid-Open No. 2008-21079 relates to a file protection system in which a user automatically saves a file being edited in a terminal device before the main motion of an earthquake arrives to protect the file. According to the invention, the earthquake information distribution server receives the emergency earthquake bulletin distributed from the emergency earthquake bulletin distribution server of the Japan Meteorological Agency, and at least each of the target areas where the one or more computer network systems in charge are present. The seismic intensity prediction value and the main motion arrival prediction time for the target area are calculated, and the earthquake information including them is broadcast via the communication network. The client terminal is connected to the earthquake information distribution server and the earthquake information distribution server via the communication network, and automatically saves the file being edited when the earthquake information is broadcast.

The above invention protects data or information by automatically saving a file before the arrival of earthquake motion, but it does not relate to the control of a plurality of different types of control objects. This is the same as the above-described invention in that there is no technical idea that prioritizes the control target devices and appropriately controls the plurality of control target devices before the arrival of the seismic wave.

  If there are devices that need to perform emergency processing based on control from the server in the event of an earthquake at multiple installation locations, a job will be issued for each device within the limited time until the seismic wave reaches the device installation location. Forcibly shut down, shutdown, power off or on. In addition, while the importance of the device, the strength (weakness) against earthquake motion, and the contents of processing that must be performed during an earthquake are unique to the device, the strength of the earthquake motion and the time to reach it are These variables vary from earthquake to earthquake depending on parameters such as the magnitude of the earthquake and the distance from the epicenter. Therefore, in the event of an earthquake, the seismic intensity and margin time that varies depending on the device installation location, the strength (weakness) of the seismic motion that varies depending on the device, the time required for control, etc., are considered before the earthquake wave arrives. It is necessary to perform the most effective control within a certain time.

The present invention aims to solve the above problems,
Receiving an earthquake early warning,
Performing a seismic intensity prediction of an evaluation point registered in advance using the emergency earthquake early warning and a margin time prediction until reaching the seismic wave;
The step of determining the priority of the control target device provided at the evaluation point using the predicted seismic intensity and the predicted margin time of the evaluation point obtained by the step and the importance factor given in advance to the control target device When,
A device control method based on an earthquake early warning having a step of controlling a device to be controlled based on the priority order is proposed.

  The earthquake early warning is information on an earthquake that is distributed immediately after an earthquake occurs (at least for a certain area) and before an earthquake wave arrives, and can be used for device control. Currently, information on the earthquake occurrence time, the estimated location of the epicenter, the magnitude, and the region where the seismic intensity is predicted to be 4 or higher in some cases is distributed from the Earthquake Early Warning Distribution Server of the Japan Meteorological Agency as the Earthquake Early Warning. The emergency earthquake bulletin in the invention is not limited to the information distribution subject and contents as long as it is information about an earthquake that can be used for controlling the device at the time of the earthquake. For example, the information source may not be the Japan Meteorological Agency, or may be information from a processor who has processed information from the Meteorological Agency.

If the earthquake early warning includes the predicted seismic intensity of the evaluation point where the device that needs to be controlled during the earthquake is included, the predicted seismic intensity can be used, but the evaluation is not included in the emergency earthquake early warning For a point, the seismic intensity of the evaluation point is predicted from the magnitude, epicenter distance, etc. using a certain relational expression. The predicted seismic intensity may be based on the Japan Meteorological Agency seismic intensity scale, but may directly indicate other variables indicating the intensity of seismic motion, such as maximum acceleration.
The time to reach the seismic wave is the time (seconds) until the main motion or S wave of the seismic wave reaches the evaluation point. However, when the initial tremor or the P wave has a strength greater than a predetermined value, both the allowance time and the predicted seismic intensity calculated for the initial tremor can be used in combination. If the earthquake early warning includes the time of arrival of the seismic wave at the evaluation point, this can be used, but it is also possible to calculate the time of arrival of the seismic wave at the evaluation point using various formulas. It is the same.

The importance coefficient given in advance to the device to be controlled is a coefficient indicating the magnitude of damage when the device is damaged. Alternatively, the importance coefficient is a coefficient that individually indicates evaluation items such as the susceptibility of the device to damage due to earthquake motion, the magnitude of damage in the event of damage, the length of time required for control, etc. It may be a coefficient generally shown.
The priority order of the device to be controlled is the order indicating the order in which control or control preparation is started for the device.
Control of the control target includes forcible job termination, job cancellation, backup creation, shutdown, power off or on, etc., but is not limited to the above as long as it is necessary for reducing damage caused by earthquake motion. .

  Since the present invention assigns priorities to the devices to be controlled and performs control based on the priorities, measures are taken in order from the most important devices by maximizing the precious time before the arrival of the seismic wave. be able to. This is extremely realistic and considering that there are limited devices that can be controlled within a limited time because the network resources are limited and control requires a certain amount of time. It is an effective control method.

The seismic intensity prediction and the surplus time prediction until the arrival of the seismic wave adopt the prediction information for an evaluation point that includes the prediction information in the preliminary report, and the preliminary report for an evaluation point that does not include the prediction information in the preliminary report. The predicted seismic intensity and the estimated margin time until the arrival of the seismic wave can be calculated using the included earthquake information and the geographical information of the evaluation points registered in advance.
According to this method, the device can be effectively controlled even for evaluation points that are not included in the earthquake early warning.

The geographic information of the evaluation point is the latitude / longitude of the evaluation point. However, the degree of ground amplification indicating the degree of amplification of ground motion by the ground can be included. Furthermore, it is possible to consider an amplification factor representing the amplification of the ground motion by the building where the device is installed.
Earthquake motion generally tends to be amplified based on the structure and characteristics of the ground while propagating through the sedimentary layer from the ground motion prediction platform to reach the ground surface. Predicted seismic intensity can be obtained. The same applies to buildings.

The step of determining the priority order of the device to be controlled includes the step of determining the priority order of the evaluation points using the predicted seismic intensity of the evaluation points, the estimated margin time, and the importance factor given in advance to the evaluation points, Preferably, the method includes a step of determining a priority score of the control target device for each evaluation point based on the priority order of the points, and a step of determining the priority order of the control target device based on the priority score. Alternatively, the control may be executed by determining the priority order of the devices for each evaluation point according to the priority order of the evaluation points.
Efficient use of limited time to arrival of seismic waves by prioritizing evaluation points close to the epicenter or evaluation time points with a short margin time to the arrival of ground motions at the same time with high predicted seismic intensity be able to. Alternatively, the most rational management (shutdown or the like) can be executed by controlling the device having the highest priority with priority over others. Here, it may be an operation that the control is not performed for a device that is predicted to have a short margin time or that an earthquake wave has already arrived and cannot be controlled in time.

  In the step of determining the priority order of the devices to be controlled, the priority score is determined for all devices included in all target evaluation points without setting the priority order for the evaluation points, and the device's priority is determined based on the priority score. A priority order may be determined. Alternatively, first, the priority order of the evaluation points is determined, and then the priority score of the device provided for each evaluation point is determined according to the priority order of the evaluation points, and the priority score of the device is determined for all target evaluation points. The priority order of the device may be determined later. The target evaluation points may be limited in advance using the magnitude and the epicenter distance, and when determining the priority order of the evaluation points, the evaluation points whose evaluation score priority score is a predetermined value or less May be determined to not control the device.

  When the earthquake early warning is notified multiple times and the accuracy of information gradually improves, the step of receiving the emergency earthquake early warning, the step of predicting the seismic intensity and the time to reach the seismic wave, and the device to be controlled And determining the priority order of a plurality of times so that the device control based on the earthquake early warning is given priority over the device control based on the previous earthquake early warning.

  If the earthquake early warning contains information on accuracy, the accuracy can be used, and if information on accuracy is not included, the accuracy of the later information is higher than the accuracy of the previous information It is possible to give priority to control based on information later.

Furthermore, based on the accuracy information included in the earthquake early warning, when the earthquake early warning is lower than a predetermined accuracy, connection with the controlled device is started, and when the early warning is higher than the predetermined accuracy, the controlled device The control may be started.
In this case, it is possible to achieve both quick execution of management and elimination of useless management. In other words, by starting connection with a device that requires a certain amount of time based on low-accuracy information and starting actual management with higher-accuracy information, it is quick to obtain high-accuracy information. Necessary management can be performed.

The present invention further determines the order of contact with the employees using the predicted seismic intensity, the employees associated in advance for each evaluation point, and the contact conditions with the employees,
A message may be sent to the employee according to the order.
The employee has some responsibility regarding the management of the device for each evaluation point. For example, the employee is a network manager or a sales manager. The message transmitted to the employee is desirably set in advance according to the predicted seismic intensity, the type of the management target device, and the like.

The present invention also provides
A receiving device for receiving the earthquake early warning;
An arithmetic unit that performs seismic intensity prediction of an evaluation point registered in advance using the earthquake early warning and prediction of margin time until arrival of an earthquake wave,
An apparatus for determining the priority of the control target device provided at the evaluation point using the predicted seismic intensity and the predicted margin time of the evaluation point obtained by the above-described step and the importance factor given in advance to the control target device When,
An apparatus for controlling a device to be controlled based on the priority order is provided.

  The arithmetic device that performs seismic intensity prediction and the time to predict the arrival of the seismic wave and the device that determines the priority of the device to be controlled may be the same device or different devices. Furthermore, the apparatus that controls the device to be controlled may be the same apparatus as the former two or another apparatus. Controlling the target device includes sending a command to the device through a service line with the Internet. When the device for controlling the device is a device different from the arithmetic device and the device for determining the priority, the former preferably controls the device based on an instruction from the latter.

The present invention also provides computer software for causing the system to execute any of the above methods.
The execution of a series of methods from receiving earthquake early warning to device control according to the present invention can be realized only by a computer, and specifically, the computer is executed only by computer software for executing such method. Can be made.

  Finally, the computer software of the present invention can be implemented on a computer via a computer-readable storage medium storing the computer software.

BEST MODE FOR CARRYING OUT THE INVENTION

  Below, the form for implementing this invention based on an Example is described. The description relating to the accompanying drawings and examples is given to help understanding of the present invention, and the present invention is not limited to the description of these drawings and examples.

FIG. 1 is a flowchart showing a process flow in device control based on an earthquake early warning based on one embodiment of the present invention.
First, as a process 1 (initial process), the system performs information related to the earthquake early warning distribution service, geographical data (latitude / longitude, ground amplification degree, etc.) related to management target evaluation points, employee data (association with evaluation points, The communication means etc.) is taken in beforehand.

Next, in process 2 (distribution service connection), the service is provided to the primary distribution service provider (usually the Japan Meteorological Agency) or secondary or high-order service provider (NTT or public organizations, specific delivery service providers, etc.) Connecting.
At the stage of processing 3 (emergency earthquake early warning reception standby), in preparation for receiving an emergency earthquake early warning at the time of an earthquake with the above processing completed. Up to this point, preparation processing is performed before the earthquake.
When an earthquake occurs, if an earthquake early warning is received in Process 4 (Seismic intensity / time margin prediction calculation), the earthquake parameters (location of the earthquake, magnitude, etc.) included in the emergency earthquake early warning and the latitude / longitude of the evaluation point, Based on the ground amplification, etc., the seismic intensity at the evaluation point and the time to reach the seismic wave are calculated.

In the process 5 (evaluation score scoring), each evaluation score is scored based on the predicted seismic intensity for each evaluation score and the surplus time until reaching the seismic wave. The scoring result is an index representing the degree of necessity of emergency management for each evaluation point in the earthquake.
In process 6 (device control scoring), scoring is performed for each device provided in the evaluation point using the scoring result of each evaluation point. The scoring result for each device is an index representing the degree of necessity of emergency management for each device in the earthquake. In this embodiment, the scoring result of the evaluation point provided with the device is used for scoring for each device, but the device uses the predicted seismic intensity for each evaluation point and the time to reach the seismic wave directly. It is also possible to perform scoring. In that case, in the process 5, it is sufficient to calculate the predicted seismic intensity of the evaluation point and the margin time until the arrival of the seismic wave.

  In process 7 (employee transmission scoring), scoring of employees associated with the evaluation score is performed based on the evaluation score and the scoring result of each device. The scoring result is an index indicating the degree of urgency of contact with the employee. In the present invention, the process of employee communication scoring and communication to employees is optional and can be omitted. Alternatively, you can perform employee transfer scoring and the employee transfer described below after completing control of the device, and you can bypass employee transfer scoring and send the transfer to all employees. You can also.

  In process 8 (device control), predetermined control is performed on devices that need to be controlled in the order of device scores. The predetermined control may be one type of control on or off (for example, one of emergency stop, shutdown, etc.) for each device, or a plurality of controls (emergency stop, shutdown, forced job termination) , Backup creation, etc.) may be selected according to the score. Further, it may be executed at the same time according to some scores of the plurality of controls.

  Here, if there are a lot of devices that need to be controlled and it is judged that the load is high to control with this server, the device control is delegated to one or more client functions arranged separately. Also good. Alternatively, a configuration in which one or more client computers originally control other computers based on an instruction from the server may be used. In that case, the client can also include performing its own control. A work flow when the client performs control based on an instruction from the server will be described with reference to a separate drawing.

  In process 9 (employee transmission), transmission is performed to employees who need to be transmitted in the order of employee transmission scores. It is desirable that the contents of the transmission display the magnitude of the earthquake that occurred, the location of the epicenter, the seismic intensity of the evaluation point in charge, the score of the device, etc. according to a predetermined format.

  After the above procedure is completed, the process returns to process 3 (Earthquake early warning reception standby) and waits for reception of the next emergency earthquake early warning. Multiple earthquake early warnings are delivered at the time of one earthquake occurrence, and the accuracy of information is improved for reasons such as the number of observation points used in the latter is generally increased. It is desirable to prioritize device control and employee communication based on previous bulletins. If information regarding accuracy is included in the bulletin, the information can be used.

FIG. 2 is a flowchart illustrating the details of the process 4 (seismic intensity / margin time prediction calculation) in more detail. The seismic intensity of the evaluation point and the time to reach the seismic wave are calculated by using the earthquake parameters (seismic source position, magnitude, etc.) included in the earthquake early warning, the latitude / longitude of the evaluation point, and the ground amplification degree. The seismic intensity prediction formula by the Japan Meteorological Agency can be used for the seismic intensity of the evaluation point, but any other formula can be used as long as it can calculate the seismic intensity of the evaluation point from the magnitude and the epicenter distance. You can also.
Furthermore, although the prediction formula of the Japan Meteorological Agency can be used to calculate the seismic wave arrival allowance time for each evaluation point, other methods may be used similarly to the calculation of the predicted seismic intensity.
FIG. 2 shows a procedure for calculating the predicted seismic intensity and the seismic wave arrival time for each evaluation point, and calculating the predicted seismic intensity and the seismic wave arrival time for the next evaluation point after calculating these two values. First, it is possible to calculate predicted seismic intensity for all evaluation points, and then to calculate seismic wave arrival allowance time for all evaluation points.
FIG. 2 shows an example of predicted seismic intensity and predicted seismic wave arrival time predicted by the above method. At the evaluation point A1, a seismic intensity of 4 is predicted after 17 seconds, a seismic intensity of 3 is estimated after 41 seconds at the evaluation point A2, and a seismic intensity of 5 strong is predicted after 5 seconds at the evaluation point A3. With regard to the evaluation points A1 to A3, since the strongest earthquake motion is predicted in the future where the evaluation point A3 is the closest, it is predicted that the priority of control will be higher.

  FIG. 3 is a flowchart illustrating the processing contents of processing 5 (evaluation score scoring) in more detail. In the process 5, a score representing the degree of necessity of emergency management for each evaluation point in the earthquake is calculated based on the predicted seismic intensity for each evaluation point and the allowance time until the arrival of the seismic wave. The score is calculated by the following formula, for example.

Formula 1

スコアを算出する際は、予測震度の値を何らかの方法で数値化して用いることが望ましい。数値化の方法は、例えば、震度３に対して２．０、震度５弱以下に対して３．０等の数値を割り付ける方法、あるいは予測震度の値をそのまま用いて、予測震度が５強であれば、例えば予測震度５．３のような値を付与する方法がある。また、余裕時間についても、時間あるいは秒数そのものではなく、表２に示すように、１０秒以下に対して５．０、３０秒以下に対して４．０のように、余裕時間が短いほどたかい数値を付与することが必要である。

When calculating the score, it is desirable to digitize the predicted seismic intensity value by some method. The quantification method is, for example, a method of assigning numerical values such as 2.0 for seismic intensity 3 and 3.0 for seismic intensity 5 or less, or using predicted seismic intensity values as they are, For example, there is a method of giving a value such as a predicted seismic intensity 5.3. Also, the margin time is not the time or the number of seconds itself, but as shown in Table 2, as the margin time is shorter, such as 5.0 for 10 seconds or less and 4.0 for 30 seconds or less. It is necessary to give a high numerical value.

Tables 1 and 2 show conversion values of seismic intensity and seismic wave arrival time that can be used when scoring the evaluation points and devices. The higher the predicted seismic intensity, the higher the score, and the shorter the spare time, the higher the score. These values reflect the need to increase the priority and control for evaluation points where greater ground motion is predicted in the near future. For these scoring, other scoring tables can be used, and as described above, the seismic intensity may be simply quantified (5 for seismic intensity 5 and 5.3 for seismic intensity 5). As for the margin time, numerical processing such as taking the reciprocal of time is also possible.

  FIG. 3 shows the score calculation result together with the processing procedure in the processing 5. According to FIG. 3, the score of the evaluation score A3 is 48, which is the highest score among the evaluation scores, which is consistent with the fact that A3 is predicted to have the highest control priority in FIG. ing.

Table 3 exemplifies parameters for each evaluation score that can be used when calculating the score of the evaluation score. The displayed parameters are the evaluation point name, client connection information, latitude / longitude, ground amplification indicating the degree of amplification of ground motion from the ground motion prediction platform to the ground surface, predicted seismic intensity coefficient equivalent to sensitivity to predicted seismic intensity, margin time Is a margin time coefficient indicating the necessary degree, and an importance coefficient indicating the importance of the evaluation point. Needless to say, these can be used in appropriate combinations, and parameter definitions can be changed and new parameters can be adopted.

  FIG. 4 is a flowchart showing details of the process 6 (device control scoring). For example, the score for each device can be calculated by the following equation.

Formula 2

演算の結果、評価点Ａ３に設けられている２つのデバイスＤ３０１とＤ３０２のスコアが最も高くなっており、最も速やかな制御が必要であることが示されている。デバイス毎のスコアの算出に関しても、上記以外の方法、たとえば設置されている評価点の予測震度と予測余裕時間をデバイスの重要度係数と組み合わせて計算する方法であっても良いことは自明である。

As a result of the calculation, the scores of the two devices D301 and D302 provided at the evaluation point A3 are the highest, indicating that the quickest control is required. Regarding the calculation of the score for each device, it is obvious that a method other than the above may be used, for example, a method in which the predicted seismic intensity and estimated margin time of the installed evaluation point are combined with the importance coefficient of the device. .

Table 4 exemplifies the importance coefficient for each device and other parameters assigned to the device. Taking the device of D101 as an example, the name is “warning lamp 101”, the device type is “messenger”, the control pattern is “seismic intensity of 4 or more”, the importance coefficient is “0.800”, and the like. The control pattern of “seismic intensity 4 or higher” indicates that the warning light 101 needs to be turned on when the predicted seismic intensity is 4 or higher.

FIG. 5 is a flowchart showing details of the process 7 (employee transmission scoring). The employee transmission score can be calculated by the following formula, for example.

Formula 3

関連度係数は、従業員と当該評価点との関連性の強さを示す使用であり、例えば、防災担当従業員については１．０、一般従業員であれば０．２と設定する。従業員に対してメッセージを送信するか否かは伝達パターンによって定義された震度閾値によるが、関連度の高い従業員ほど、メッセージの送信順序は優先される。
表５と表６には、それぞれ従業員に対して設定された伝達パターン等のパラメータと、評価点と従業員の関連度係数を示す。

The relevance coefficient is a use indicating the strength of relevance between an employee and the evaluation point. For example, 1.0 is set for a disaster prevention employee and 0.2 is set for a general employee. Whether or not to send a message to an employee depends on the seismic intensity threshold defined by the transmission pattern, but the higher the relevance of the employee, the higher the order of message transmission.
Tables 5 and 6 show parameters such as transmission patterns set for employees, evaluation points, and employee relevance factors, respectively.

  Table 7 (uppermost table) shows the result of determining whether or not the predetermined control is necessary for the devices that need to be controlled in the order of the device score in the process 8 (device control). First, the devices are rearranged according to the priority order, and the necessity of control is determined for each device by comparing a preset control pattern with the predicted seismic intensity. In this case, further, referring to the accuracy of the used earthquake early warning, if the accuracy is lower than the predetermined value, even if it is determined that control is required, only connection with the control device is performed, and You may wait for the high information of the system.

Table 7 (middle table) shows the result of rearranging devices according to their priorities based on the scoring results and the control device table in the process 8 (device control) described above, and extracting only the devices that need to be controlled. Is illustrated.

  According to the processing procedure of the processing 8 (device control) shown in FIG. 6, the processing amount of the device that needs to be controlled is totaled and compared with a preset upper limit of the processing amount. Different. If the total processing amount of devices that need to be controlled is less than or equal to the upper limit, the server controls each device based on the middle table (Table (B)) in Table 7. However, if the total processing amount of the devices that need to be controlled exceeds the upper limit, a device control proxy instruction is transmitted to the client based on the table shown in the lower part of Table 7 (Table (C)). An example of data to be transmitted to the client at that time is shown on the right side of FIG. Therefore, the server executes only control of devices that cannot be controlled by the client.

  FIG. 7 is a flowchart showing details of control performed on each device arranged in accordance with the priority order. For devices for which control is determined to be necessary, the device is connected at the stage of connection with the control device, but if the earthquake early warning is of low accuracy, the procedure for moving to the next device control without performing device control It has become. The device control may be performed regardless of the accuracy of the earthquake early warning, or the accuracy of the early warning necessary for executing the control may be set for each device.

Table 8 shows the result of processing 9 (employee communication). By the above method, the employees are rearranged in the order of employee transmission scores, and at the same time, the necessity of transmission is determined by comparing the transmission pattern with the predicted seismic intensity. Since the necessity of transmission is calculated independently of the priority order, the transmission is not necessarily performed to employees with higher priority.

   Here, as described in paragraph [0030], when there are a large number of devices that need to be controlled and it is determined that the load is high to control with this server, one or more separately arranged devices A flow in the case where the client function computer performs device control on behalf will be described with reference to FIG. As shown in FIG. 8, the client function computer first reads the control device information from the database and starts the system (process 1), connects to the server of the system based on the present invention (process 2), and controls from the server. Wait until the proxy instruction data is distributed (process 3).

  When the processing proxy instruction is received from the server, the client function computer determines whether it is already connected to the device to be processed (processing 5), and if it is not connected to the device, it connects to the control device. If the device is already connected, this step is skipped and the process proceeds to the next step. In the next step, it is determined whether or not the earthquake early warning is low-accuracy based on information included in the control proxy instruction from the server (Process 7). In the case of accuracy, only preparation for control execution is performed, and the process waits until high-precision information is received. The client function computer repeats the processes from (Process 5) to (Process 7) as many as the number of devices described in the control proxy instruction data from the server.

  The server may delegate the control of the device to one or a plurality of client function computers, or may delegate only a part of the control. In addition, the server may determine which client function computer should perform device control depending on the number of devices, the degree of urgency of control, the number of client function computers that can perform control, and the like. good.

  When the client function computer performs device control, as described in Table 4, whether or not control from the client is possible for each device (displayed as “client control” in Table 4) is set in advance. The server refers to the information and instructs the client which device among the devices that can be controlled by the client is to be delegated. In Table 4, all devices other than the device with the code D301 can be controlled from the client.

Table 9 shows an example in which the control device tables related to a plurality of sites managed by the server are divided into device tables that can be controlled by clients at each evaluation point. Based on the control proxy instruction from the server, the client refers to Table 9 and controls each device as necessary.

  As is clear from the above, when the method according to the present invention is used in comparison with the conventional method, the device that requires more urgent control is preferentially controlled based on the earthquake early warning. Therefore, it is possible to realize a rational measure of controlling the devices in order from the device that needs to be controlled before arriving.
