Somebody is walking the aisle while the full ladle is moving
Half past two in the morning, rail aisle between the furnace and the casting bay. A full ladle hangs from the overhead crane and is moving to the right; the metal glows red at the mouth. Along the marked walkway a single person in a blue helmet is walking the other way. On the left, a shunting locomotive waits with its wagon. Three colleagues watch from behind the yellow and black barrier. Nobody else is inside the aisle.

The rule
You decide once. IRIS applies it always.
If
there is a person in the aisle while a loaded ladle is moving
Then
- alert the crane driver and the control room with the camera and the point in the aisle
- save the video from the moment the person entered the aisle
- add the entry to the shift count of unauthorised access
The instruction that set it up«Tell me if anybody enters the rail aisle while the crane is carrying a ladle with metal in it.»
What changes
What changes for whoever answers for the plant
Under a full ladle there is no margin: if something falls, it falls on top. That aisle is closed while the load is moving, and almost always it is. The problem is the times it is not. With the camera, the crane driver and the control room see the person inside the aisle while they are still walking, with the picture and the exact point. And over a month there is a number of unauthorised entries per shift, which shows whether the shortcut is one person or already a habit.
What people usually ask
Does IRIS know who walked into the aisle?
No. IRIS does not recognise faces and does not match anyone against a list. It sees that a person is inside the aisle while a load with metal is moving, and that is what it reports: the point, the camera and the time. Who it was comes from the plant access control or from whoever reviews the video. The rule is written about the situation, not about the person, and in a steelworks that difference is welcome.
Can IRIS stop the crane?
No. IRIS does not act on any machine. It alerts the crane driver and the control room while the person is still in the aisle, and saves the video from the moment they walked in. Halting the load, sounding the horn or closing the walkway is decided by a person, following the plant procedure. The value is that the alert arrives while something can still be done, not in the report the next day.
Does it work at night, with the glare of the ladle?
Yes. This scene is from the small hours and it is the normal case in a steelworks: a dark bay, floodlights and one very strong light source moving overhead. The camera settles into that mix, and the outline of a person on the marked floor still reads. Where the shot is washed out by the glare, that gets said and the camera is repositioned: better to move the camera than to trust a bad picture.

Simulation · how IRIS works
A new case each time. Always the same screen.
It plays by itself and shows one case from start to finish. It is a summary: the real screen has far more functions than fit in this box.
- The rule gets built
- It goes to every camera
- Published, it watches alone
- And then it fires

Public safety
What can a camera see without pointing at anyone?
13 cases: 9 raise an alert when something happens and 4 only measure. You see each image as it is, and then with what IRIS understands on top.
Data centres
What if the outage does not start with an attack?
13 cases, and in every one of them IRIS raises an alert when something happens. You see each image as it is, and then with what it understands on top.
And the best part
The rule does not decide anything.It just never forgets, and it tells the person who decides.
You write once what needs watching, and it holds at three in the morning just as at noon. What to do with the alert is still a person’s decision.
Tell us your problem and we will say whether IRIS understands it, or not yet.
