Abstract

Data can be received indicating an occurrence of an alarm in an industrial machine monitoring system, the alarm triggered in response to machine operation satisfying a condition. A notification plan associated with the alarm can be accessed. The notification plan can specify parameters for contacting a user in response to the occurrence of the alarm. The notification plan can specify a time delay. A notification can be generated after elapse of at least the time delay. The generating can be according to the notification plan. The notification can be provided. Related apparatus, systems, techniques, and articles are also described.

Claims

1. A method comprising:

receiving data indicating an occurrence of an alarm in an industrial machine monitoring system, the alarm triggered in response to machine operation satisfying a condition;

accessing a notification plan associated with the alarm, the notification plan specifying parameters for contacting a user in response to the occurrence of the alarm, the notification plan specifying a time delay;

generating, after elapse of at least the time delay, a notification, wherein the generating is performed according to the notification plan and includes generating at least one predefined visualization specified in the notification plan, the at least one visualization characterizing sensor measurements related to machine operation before and after a time point in which the alarm was triggered; and

providing the notification.

2. The method of claim 1, further comprising delaying processing of the notification by at least the time delay.

3. The method of claim 1, wherein providing the notification includes transmitting the notification via email, transmitting the notification via text message, or storing the notification in memory.

4. The method of claim 1, wherein the industrial machine monitoring system includes a sensor and computing device, the sensor coupled to and observing operational information of a machine and relaying the observed operational information to the computing device for storage and analysis, the computing device comparing the operational information to predefined alarm trigger conditions and generating the alarm in response to the operational information satisfying at least one of the alarm trigger conditions.

5. The method of claim 1, further comprising:

determining, after an elapse of time that is at least the time delay, a state of the alarm;

wherein the generating the notification is in response to determining that the alarm is active.

6. The method of claim 1, wherein the notification plan specifies:

a recipient of the notification;

at least one applicable alarm type;

at least one applicable alarm level;

a notification suppression time;

predefined visualizations for inclusion in the notification;

alarm states for canceling the notification; and

the time delay.

7. The method of claim 6, wherein the recipient of the notification includes an email address, a telephone number, or a file path;

wherein the at least one applicable alarm type includes machine type and instrumentation type;

wherein the at least one applicable alarm level includes a level 1 alarm, a level 2 alarm, a level 3 alarm, and a level 4 alarm; and

wherein the alarm states for canceling the notification includes acknowledged, shelved, and cleared.

8. A system comprising:

at least one data processor;

memory storing instructions which, when executed by the at least one data processor, causes the at least one data processor to perform operations comprising;

receiving data indicating an occurrence of an alarm in an industrial machine monitoring system, the alarm triggered in response to machine operation satisfying a condition;

accessing a notification plan associated with the alarm, the notification plan specifying parameters for contacting a user in response to the occurrence of the alarm, the notification plan specifying a time delay;

generating, after elapse of at least the time delay, a notification, wherein the generating is performed according to the notification plan and includes generating at least one predefined visualization specified in the notification plan, the at least one visualization characterizing sensor measurements related to machine operation before and after a time point in which the alarm was triggered; and

providing the notification.

9. The system of claim 8, the operations further comprising delaying processing of the notification by at least the time delay.

10. The system of claim 8, wherein providing the notification includes transmitting the notification via email, transmitting the notification via text message, or storing the notification in memory.

11. The system of claim 8, wherein the industrial machine monitoring system includes a sensor and computing device, the sensor coupled to and observing operational information of a machine and relaying the observed operational information to the computing device for storage and analysis, the computing device comparing the operational information to predefined alarm trigger conditions and generating the alarm in response to the operational information satisfying at least one of the alarm trigger conditions.

12. The system of claim 8, the operations further comprising:

determining, after an elapse of time that is at least the time delay, a state of the alarm;

wherein the generating the notification is in response to determining that the alarm is active.

13. The system of claim 8, wherein the notification plan specifies:

a recipient of the notification;

at least one applicable alarm type;

at least one applicable alarm level;

a notification suppression time;

predefined visualizations for inclusion in the notification;

alarm states for canceling the notification; and

the time delay.

14. The system of claim 13, wherein the recipient of the notification includes an email address, a telephone number, or a file path;

wherein the at least one applicable alarm type includes machine type and instrumentation type;

wherein the at least one applicable alarm level includes a level 1 alarm, a level 2 alarm, a level 3 alarm, and a level 4 alarm; and

wherein the alarm states for canceling the notification includes acknowledged, shelved, and cleared.

15. A non-transitory computer program product storing instructions,

which when executed by at least one data processor of at least one computing system, implement operations comprising:

receiving data indicating an occurrence of an alarm in an industrial machine monitoring system, the alarm triggered in response to machine operation satisfying a condition;

accessing a notification plan associated with the alarm, the notification plan specifying parameters for contacting a user in response to the occurrence of the alarm, the notification plan specifying a time delay;

generating, after elapse of at least the time delay, a notification, wherein the generating is performed according to the notification plan and includes generating at least one predefined visualization specified in the notification plan, the at least one visualization characterizing sensor measurements related to machine operation before and after a time point in which the alarm was triggered; and

providing the notification.
