When planning a system deployment, regardless of size, it's critical to take a look at not just the initial costs of the hardware and software, but also at the continuing operational expenses. Many elements make a contribution to these costs and the right embedded PC system customarily offers advantages in the long term:
System Reliability:
Because Inserted PC applications have long run and are required to operate in harsh environments including wide temperature ranges, shock, vibration and humidity. Embedded PC systems usually contains components rated for higher temperatures and/or higher voltages. Conversely, commercial Computer system designs regularly employ parts with lower temperature/voltage ratings because those parts are inexpensive, readily available, and support the operating conditions for everyday PCs in an ordinary indoor conditions. The lifespan of any electronic device is related to its operating temperature and the other conditions, but the main issue will be the need operating temperature.
As an example, using an electronic component that rated for a worst-case guaranteed life of 2000 hours at 85C but operated at 55C which normally used on the Desktop PC motherboard, would have an expected life of 16,000 hours or simply under 2 years of continual (24x7x365) operation. Conversely, The same component rated for a worst-case assured life of 2000 hours at 110C but operated at 55C, would have an expected life of 64,000 hours or simply over 7 years of constant operation. To explain, increasing the temperature rating of the component by 20C increases its anticipated life by 4x.
While plausibly trivial, these capacitors are very important in maintaining steady voltage levels and suppressing noise in high speed Printed Circuit Board (PCB) designs. Thus increasing the System Trustworthiness.
Power Consumption:
Embedded PC system Lower energy usage is always better than higher energy consumption but not only for the simple reasons of saving energy costs and increasing battery charge lifespan. Low energy consumption leads to many other benefits that may not be intuitively obvious to the casual observer. First of all, lower power usage of vital parts ends up in the entire system operating at a lower temperature, putting reduced stress on the rest of the system components, and augmenting the life of the system as mentioned above. Low power usage can frequently obviate the requirement for a fan which allows the system to run quieter, enables smaller enclosures, and lowers implementation and support costs. Low power consumption combined with power management technology built into the silicon itself, also eases the imposition on software engineers who are increasingly tasked with developing sophisticated applications and methodologies for managing system power.
