The positioning of the LCD advertising machine is a commercial LCD. After removing the LCD screen, the most important thing must be the requirements of the motherboard. Because of the positioning, the application scenarios of the LCD advertising machine have many possibilities, such as: humidity, high temperature, low temperature, etc. ;There may also be long-term operation requirements, so these problems make it impossible for the LCD advertising machine to use the commercial motherboard used on the ordinary PC side, but to use a more stable and reliable industrial control motherboard. Let's take a look at the ordinary commercial motherboard and industrial control motherboard. difference.

Commercial motherboard:
Commercial motherboards, because of their relatively fast replacement speed and relatively low requirements for product stability and use environment, pursue the timeliness of products and the market positioning of their own products, and generally only need to select components. It is enough to meet the service life of the system for 2 to 3 years (most of them have been replaced after 3 years), and the materials of the components can be used with ordinary grades. One is to consider the use of products in the commercial market, and the other is to reduce the cost of the motherboard.
Industrial control board:
The material selection of the industrial control motherboard will select the components that have been verified for a long time and have high requirements to ensure the high reliability requirements of the product under harsh conditions. For example, the components of industrial control motherboards need to adapt to a wide temperature environment (-20 degree 60 degree ), such as solid capacitors, to ensure that they can be used in harsh environments (permanent power-on during life, harsh weather, humidity, vibration, dust, radiation, high temperature, etc. etc.) work normally; motherboard components need to be resistant to high temperature, moisture, etc. Through special design, the industrial control motherboard can realize functions such as automatic restart of the watchdog and anti-surge shock when encountering abnormal situations such as crashes, so as to fully ensure the high stability of the system in harsh environments.
