  Conventionally, in the building group management system that monitors and manages the facilities of multiple buildings, the management device installed in each building collects information on various controllers connected via communication lines and alarm information generated on site, The group management apparatus is notified (see Patent Document 1 and Patent Document 2). The operator of the building group management system deals with the alarm according to a procedure instructed in advance according to the notified alarm. The operator handles each alarm in the notified order.

Japanese Patent Laid-Open No. 9-251591 JP 2013-198022 A

  According to the conventional building group management system, there is no problem when the alarm notification from each building is sporadic, but when an alarm occurs frequently in a short time in a specific building, Responses to alarms occurring in other buildings will be made after all alarms that have occurred frequently have been dealt with, making it impossible to respond quickly.

  For example, it is assumed that 200 alarms are generated from 10:00 to 10:03 in the building A, and one alarm is generated in the building B at 10:04. If it takes 30 minutes to deal with 200 alarms for building A, the alarm for building B will be dealt with after 26 minutes. Due to such a delay in handling, there is a possibility that the manager of the building B may complain to the operator of the building group management system. In addition, if the alarm of the building is an alarm with a high degree of emergency such as an intrusion alarm or a water leak alarm, a delayed action may cause a fatal accident.

  If a large number of terminals and operators of the building group management system can be allocated, the delay in handling can be reduced. Usually, however, multiple buildings are monitored by the minimum number of operators due to operational cost and work space limitations. become. Therefore, it is desirable to be able to deal with alarms in a plurality of buildings in a timely manner even if alarms are frequently generated in a specific building.

  The present invention was made in order to solve the above-described problem, and even if alarms occur frequently in a specific building, a group management apparatus that performs alarm notification so that alarms of a plurality of buildings can be dealt with in a timely manner And it aims at providing the building group management method.

The present invention relates to a group management apparatus in a building group management system that monitors facilities of a plurality of buildings, an alarm receiving unit that receives an alarm from the building management apparatus that monitors the facilities of each building, and a priority value of alarm notification For each building, priority determination means for lowering the priority of the building that issued the alarm each time an alarm is received from the building management device, and an operator in the normal mode of alarm notification And alarm output means for performing alarm notification to the operator in the order of the priorities in the alarm frequent occurrence mode.
Further, according to one configuration example of the group management device of the present invention, the alarm notification mode is changed from the normal mode to the alarm frequent occurrence mode when the number of times the alarm is received from the same building within a predetermined time is a predetermined number or more. It is characterized by comprising notification mode changing means for changing to
Moreover, in one structural example of the group management apparatus of this invention, whenever the said priority determination means receives the warning from the said building management apparatus, the said priority of the building which issued this warning is lowered | hung, and more than fixed time or more When there is a building that has not issued a warning for a certain period, the priority of the building that has not issued a warning for a certain period of time is increased.
Moreover, in one structural example of the group management apparatus of this invention, the said priority determination means receives the warning from the said building management apparatus, When lowering the said priority of the building which issued this warning, the said priority The updated priority value is determined based on the current priority value of the building stored in the storage means and the importance level of the alarm that has occurred.

  In the building group management method for monitoring facilities of a plurality of buildings, the present invention receives an alarm from the building management device that monitors the facilities of each building, and receives the alarm from the building management device. Each time, the priority storage means for storing the priority value of the alarm notification for each building is stored, the priority determining step for lowering the priority of the building that issued the alarm, and the operator in the normal mode of the alarm notification The alarm notification step is performed in the order of alarm occurrence time, and in the alarm frequent occurrence mode, the alarm output step is performed in which the alarm notification to the operator is performed in the order of the priorities.

  In the present invention, the priority of the alarm notification is provided for each building, the normal mode and the alarm frequent occurrence mode are provided as the alarm notification mode, and the priority of the building that issued this alarm each time an alarm is received from the building management device Lower. Thus, in the present invention, if the alarm notification mode is manually or automatically set to the alarm frequent occurrence mode, the list of alarms is displayed in the order of priority of the alarm notification, and the specific building where the alarm is frequently generated is displayed. Since an alarm other than the alarm from is displayed first, the operator can deal with alarms in a plurality of buildings in a timely manner even if alarms frequently occur in a specific building.

  Further, in the present invention, by providing a notification mode changing means for changing the alarm notification mode from the normal mode to the alarm frequent occurrence mode when the number of times the alarm is received from the same building within a predetermined time is a predetermined number of times or more, It is possible to automatically change to the alarm frequent occurrence mode.

  In addition, in the present invention, when there is a building that has not issued an alarm for a certain period of time or more, when an alarm is received from a certain building by raising the priority of the building that has not issued the alarm for a certain period of time or more It is possible to perform a process of lowering the priority of the alarm notification for a certain time and returning the priority after a certain time.

  Further, in the present invention, when lowering the priority of the building that issued the alarm, the updated priority value is determined based on the current priority value of the building and the importance of the generated alarm. Thus, the importance of the alarm can be reflected in the priority of the alarm notification.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a building group management system according to an embodiment of the present invention. The building group management system includes a group management device 1 that monitors a plurality of buildings via a communication line, building management devices 2-1 to 2-n that are installed for each building and monitor building facilities, and a group management device. 1 and a communication line 3 connecting the building management devices 2-1 to 2-n.

  The group management apparatus 1 sets the alarm receiving unit 10 that receives alarms from the building management apparatuses 2-1 to 2-n, the upper limit value, the lower limit value, and the current priority value of the priority of alarm notification for each building. Priority storage unit 11 to be stored, priority determination unit 12 to determine the priority of alarm notification for each building depending on whether or not an alarm is received, and alarm information from building management devices 2-1 to 2-n An alarm storage unit 13 for storing alarms and a display unit serving as an alarm output means for performing alarm notifications to the operator in the order of occurrence of alarms in the normal mode of alarm notification and in the order of priority in the alarm frequent occurrence mode 14, the notification mode changing unit 15 that changes the alarm notification mode according to the frequency of alarm reception, and the building management devices 2-1 to 2-n so that the building that issued the alarm can be recognized. Communication system that pre-stores addresses A section (16), and an input unit 17 for an operator to provide directions to input information to the group management apparatus 1.

  In the present embodiment, the priority of alarm notification is set for each building. This priority indicates that the higher the value, the higher the priority of alarm notification. In the alarm frequent occurrence mode, which will be described later, alarm notifications are given to the operator in this order of priority.

Hereinafter, the operation of the building group management system of the present embodiment will be described. 2 to 4 are flowcharts showing the operation of the group management apparatus 1.
The building management devices 2-1 to 2-n are installed for each building, and are controlled by various controllers that control and monitor facilities such as air conditioning facilities, lighting facilities, water supply facilities, elevators, crime prevention facilities, and disaster prevention facilities. Collect information such as equipment status information and alarms. The building management apparatuses 2-1 to 2-n transmit alarm information to the group management apparatus 1 via the communication line 3 when an alarm is generated in the facility of the building to be monitored. This alarm information includes, for example, information such as the address of the building management apparatus in which the alarm has occurred, the name of the building in which the alarm has occurred, the name of the facility in which the alarm has occurred, the alarm type, and the alarm occurrence date and time.

  The alarm receiving unit 10 of the group management device 1 receives alarm information from the building management devices 2-1 to 2-n. The priority determination unit 12 of the group management device 1 receives the alarm information from the building management devices 2-1 to 2-n when the alarm reception unit 10 receives the alarm information from the building management devices 2-1 to 2-n (step S1 in FIG. 2). NO in step S2), the priority of the alarm notification of the building where the alarm occurred is lowered by one (step S3 in FIG. 2). The priority storage unit 11 stores an upper limit value (initial value), a lower limit value, and a current priority value for the priority of alarm notification for each building. The building where the alarm has occurred can be determined by confirming the address of the building management device included in the alarm information or by confirming the building name included in the alarm information.

After determining the building where the alarm has occurred, the priority determination unit 12 lowers the priority by subtracting 1 from the priority value of the current alarm notification of the building stored in the priority storage unit 11. Thus, the priority value of the alarm notification of the building stored in the priority storage unit 11 is updated. When the priority determination unit 12 attempts to lower the priority value, this value is stored in the priority storage unit 11 and has already reached the lower limit value of the priority of the building. Keep the lower limit value without lowering the priority value.
The alarm storage unit 13 stores the alarm information received by the alarm receiver 10.

  Next, in the display unit 14 of the group management apparatus 1, the alarm notification mode is the normal mode (YES in step S2 in FIG. 2), and the number of times the alarm is received from the same building within the predetermined time T1 is less than the predetermined number. In the case (NO in step S4 in FIG. 2), an alarm notification is given to the operator of the group management apparatus 1 in the normal mode (step S5 in FIG. 2). In the normal mode, the display unit 14 displays a list of generated alarms on the screen in the order of occurrence time based on the alarm information stored in the alarm storage unit 13.

  Note that the order of occurrence time in this embodiment is usually the order in which the occurrence time is from the new alarm toward the old alarm, and the occurrence time is newer on the screen (descending order). However, it is also possible to use an order (ascending order) in which alarms with older occurrence times are arranged on the screen. The operator can select whether the order is descending or ascending. In the initial state, the alarm notification mode is the normal mode.

  Further, when the alarm notification mode is the alarm frequent occurrence mode (NO in step S2), the display unit 14 notifies the operator of the group management device 1 in the alarm frequent occurrence mode (step S6 in FIG. 2). In the alarm frequent occurrence mode, the display unit 14 displays a list of generated alarms based on the alarm information stored in the alarm storage unit 13 and the priority value of the alarm notification stored in the priority storage unit 11. Display on the screen in order of priority of the current alarm notification.

  The priority order according to the present embodiment is usually arranged in a direction from a warning with a high priority (high priority value) to a warning with a low priority (low priority value). This means an order in which the higher alarms are arranged on the screen (descending order), but an alarm having a lower priority may be arranged in the order on the screen (ascending order). The operator can select whether the order is descending or ascending. Alarms with the same priority are displayed in the order of occurrence time.

On the other hand, the notification mode changing unit 15 of the group management apparatus 1 is configured such that the alarm notification mode is the normal mode (YES in step S2), and the number of times the alarm is received from the same building within the predetermined time T1 is equal to or greater than the predetermined number (YES in step S4), the alarm notification mode is changed to the alarm frequent occurrence mode (step S7 in FIG. 2). The notification mode changing unit 15 changes the alarm notification mode to the alarm frequent occurrence mode when the number of times the alarm is received from the same building for 10 minutes is 10 times or more, for example.
The group management device 1 performs the process as shown in FIG. 2 every time it receives alarm information from the building management devices 2-1 to 2-n.

  Moreover, when the response to all the generated alarms is completed (YES in step S8 in FIG. 3), the notification mode changing unit 15 returns the alarm notification mode to the normal mode (step S9 in FIG. 3). In the alarm storage unit 13, together with the alarm information received by the alarm receiver 10, a response completion flag indicating whether the response to the alarm is completed is stored in association with the alarm information. As described above, when displaying a list of alarms in the normal mode or the frequent alarm mode, the display unit 14 displays incomplete / completed countermeasures for each alarm based on the countermeasure completion flag.

  When the handling of a certain alarm is completed, the operator of the group management device 1 operates the input unit 17 to rewrite the “handling incomplete” information of the warning to the “handling completed” information on the screen. In response to this input, the response completion flag for the alarm is changed to a value indicating that the response to the alarm has been completed. Thus, the notification mode change unit 15 can determine whether or not the response to the alarm has been completed by checking the response completion flag stored in the alarm storage unit 13.

  Next, when there is a building that has not issued an alarm for a period of time equal to or longer than the predetermined time T2 (YES in step S10 in FIG. 4), the priority determination unit 12 stores the building stored in the priority storage unit 11 The priority is raised by adding one to the priority value of the current alarm notification (step S11 in FIG. 4). Thus, the priority value of the alarm notification of the building stored in the priority storage unit 11 is updated. The process of FIG. 4 is periodically started by a timer mechanism (not shown) and is executed separately from the processes of FIGS. In addition, when the priority determination part 12 is going to raise the value of a priority, when this value has already reached the upper limit value of the priority of the said building memorize | stored in the priority memory | storage part 11, Keeps the upper limit value without increasing the priority value. The fixed time T2 is a time set in advance by the operator, and as a guideline, a standard time (for example, 30 minutes) required to deal with the alarm may be set.

  FIG. 5 is a diagram illustrating a display example of an alarm in the normal mode. As described above, in the normal mode, the list of alarms is displayed side by side so that the alarms are in order of occurrence, that is, the alarms appear higher in order of occurrence. As a result, the operator can grasp an alarm for which handling has not been completed.

  FIG. 6 is a diagram illustrating a display example of an alarm in the alarm frequent occurrence mode. As described above, in the alarm frequent occurrence mode, a list of alarms is displayed in order of priority of alarm notification. In the example of FIG. 6, since the alarms from the building A monitored by the building management apparatus 2-1 occur frequently, the priority of the alarm notification of the building A is low. On the other hand, since the priority of the alarm notification of the building C monitored by the building management apparatus 2-3 and the building B monitored by the building management apparatus 2-2 is higher than that of the building A, the alarm from the building C and the building B is received from the building A. Is displayed above the alarm. As described above, when the priorities are the same, alarms are displayed in order of occurrence time. Further, in the alarm frequent occurrence mode, the display order of alarms may be changed by the occurrence of a new alarm. The reason is that a list of alarms is always displayed based on the priority of the latest alarm notification, and the order of priority may change depending on the occurrence of a new alarm.

  As described above, in the present embodiment, the priority of alarm notification is set for each building, and every time an alarm is received, the priority of alarm notification of the building that issued this alarm is lowered, and a period of a certain time or more, If no alarm has been received, the priority of alarm notification for a building that has not issued an alarm for a certain period of time is raised. In the present embodiment, the list of alarms is displayed in the order of alarm occurrence time in the normal mode, and the list of alarms is displayed in the order of priority of the alarm notification in the frequent alarm mode. Thereby, in this embodiment, since an alarm other than the alarm from the specific building where the alarm frequently occurs is displayed first, even if the alarm occurs frequently in the specific building, the operator can Can deal with alarms in a timely manner.

  In the present embodiment, the alarm frequent occurrence mode is automatically turned on / off, but may be turned on / off manually by an operator. For example, when there is any modification such as addition of equipment, when there is a program change, during adjustment work, when the operator who sees the alarm display screen feels that there are many alarms, etc. You may make it change into a frequent occurrence mode.

  In the present embodiment, for example, considering the importance of a building, an upper limit value (initial value) of the priority of alarm notification for each building is determined in advance, and the priority is determined according to whether or not an alarm is received. However, the present invention is not limited to this, and the priority may be determined based on the current priority value and the importance of the alarm. In this case, the priority determined by the priority determination unit 12 is obtained by multiplying or subtracting a coefficient indicating the importance of the alarm by the priority value of the current alarm notification stored in the priority storage unit 11. Can be calculated with

  When the value obtained by multiplying the priority value of the current alarm notification stored in the priority storage unit 11 by the coefficient is calculated as the updated priority value, the coefficient is a value of 1 or less, and the alarm is important. A value that increases as the degree increases may be used. Thus, when an alarm occurs, the lower the priority of the alarm, the lower the priority of the alarm notification of the building where the alarm occurred. The higher the importance of the alarm, the higher the alarm of the building where the alarm occurred. The lowering of the priority of notification becomes smaller.

When the value obtained by subtracting the coefficient from the priority value of the current alarm notification stored in the priority storage unit 11 is calculated as the updated priority value, the coefficient becomes smaller as the importance of the alarm becomes higher. You can set it as a value. Thus, when an alarm occurs, the lower the priority of the alarm, the lower the priority of the alarm notification of the building where the alarm occurred. The higher the importance of the alarm, the higher the alarm of the building where the alarm occurred. The lowering of the priority of notification becomes smaller.
It should be noted that when the priority of the alarm notification is lowered and then the priority is raised in the processing of steps S8 and S9, it may be returned to the previous priority value before the priority is lowered.

  Each of the group management apparatus 1 and the building management apparatuses 2-1 to 2-n described in the present embodiment controls a computer having a CPU (Central Processing Unit), a memory, and an interface, and these hardware resources. It can be realized by a program to do. The CPU of each device executes the processing described in the present embodiment in accordance with a program stored in the memory of each device.
