What is the visual control?

Visual control is the use of visual information indicators to provide instant feedback on the process so that anyone in the environment can understand what is happening. This technique is popular in a number of settings and in some cases it is legally entrusted with safety reasons. For example, emergency valves are clearly marked, a form of visual control that allows anyone to control and ensure that passers -by are aware that the valves can suddenly and unexpectedly vent them.

There are many forms of visual control. It can consist simply of publishing operational instructions near the device. It may also include indicator lights and status messages. Electronic systems usually have a central control panel that provides information about what is happening in the system and where. It can generate error messages, highlight parts of the system that are in operation, etc. Examples can be seen in air traffic control rooms where radar monitor the incoming aircraft and onijsou marked notemeasures providing additional information.

If visual control is not present, only the operator knows what is happening and may not have a view of the whole system. Operators could know what was happening with the equipment for which they are responsible without knowing anything about the rest of the facility. For example, it may not be aware of slowing and stopping. If the operator was incapable, another person would not be able to take over immediately without visual inspection, because the person would not understand what is happening with this process.

They can be useful for visual control. These are located in a central location that allow supervisors and passers -by to see what is happening in the device. May be electronic or can be updated manually. For example, the printer may have a worktop that shows what is assigned to each print, D providing information about the status of each task. Can move the marks around the worktop and each mark corresponds toA work card that can be consulted for more information.

To contrast the visual control with other systems, it can help think about walking in the kitchen, where someone stopped part of the journey by preparing the cake. One baker missed the recipe and all tools and ingredients. It is easy to determine that the only remaining step is to mix wet and dry ingredients and insert the cake into the oven. Another baker did not miss the recipe or any supplies. The takeover of the baker would have to guess what kind of cake is produced and what to add to the dough before it is baked.
