Outlined the steps in The Process
Condition: Wiring For 3 rooms
Suppose, for example, a warehouse was partitioned into three distinct rooms—> Room 1, Room 2, and Room 3. Then consider now our aim of Having designed an interlock system that would control lighting (using bulbs) in these specific locations. Now let us have an insight into its functioning mode.
1. Input Mechanism
2. Toggle switch for each room
3. Output Illumination
4. Output coils for each room’s bulb are as shown below:
- Bulb for Room 1
- Bulb for Room 2
- Bulb for Room 3
Chaining logic
When an individual enters Room 1 and presses the toggle switch, the bulb in Room 1 gets illuminated. If he proceeds to Room 2 without switching OFF the toggle switch of Room 1, pressing on the toggle switch for Room 2 energizes the bulb in this room while turning off that of Room One due to an interlocking contact in the logic. When one goes into Room Three and depresses Switch Three, its light brightens while those above his head go dimmer. Finally, to go back, that person should use Switch Three which will open a circuit and turn off a light in that space. As a result, the bulb in Room 2 re-energizes. The interlock ensures that only one room bulb can be ON at a time.
Examples
1) Elevator doors: Locks protect the elevator doors if the elevator.
2) Factory Security Door: If the security door is open, the machine.
What is I/O Interloc?
I/O Interlocking is an important player in the field of operating systems because it guarantees safe and efficient communications between the CPU and different I/O devices. More details are coming up.
