Industrial and high-tech maintenance companies often photograph their sites for potential hazards or emergencies and then inform the appropriate person who can take action to resolve the issue. In this code pattern, you will build an app that will load images into an IBM Cloudant® database, analyze it, and based on the results, trigger an alert showing whether there is a danger and need for action.
Industrial and maintenance companies need to know what’s happening at their sites. A leak, fire, or malfunction can spell disaster for a company, resulting in dangerous situations for employees, downtime, public relation setbacks, and financial losses.
These companies have been leaders in using remote devices-phones, mounted cams, drones-to send images of various sites and equipment to be monitored for any malfunctions. But what if you could automatically analyze those images and send an alert about the location or potential emergency situation?
If you’re a developer working for a company that relies on site images, you can now build an application that analyzes an image and sends an alert automatically. In this code pattern, you’ll use IBM Cloud Functions to analyze an image and send it to the Watson™ IoT Platform. The image will be assigned a score, and that score will be evaluated to trigger any necessary alerts to reach authorities through the best available communication channel (for example, email, text, or push notifications).
You have the option to develop a standalone application that can be easily updated or modified to work from within a smart device, or run it on a browser on your laptop or phone.
In the pattern use case, you’ll learn how to send an image for processing that detects a fire. (You can also use this same app for maintenance alerts or other emergency alert detections.) The fire is identified by the Watson Visual Recognition service, and the Node-RED app will subsequently notify the appropriate resources.
There are multiple ways to design this process, and you can modify the pattern to extend it to other real-world use cases, sending alerts to other designated recipients and creating additional designated channels for alert notifications.
You’ll create an app based on the following flow:
A Node-RED flow continues to read these events from the device on the IoT Platform and triggers alerts based on the image’s features. For example:
alert: EMERGENCY ALERT!
