Under the promotion of smart city construction, unattended smart display equipment not only solves the problem of shortage of human resources, but also effectively improves service efficiency. Therefore, the development is extremely rapid, not only in terms of category expansion, but also in exponential growth in quantity. At the same time, the environment in which smart display devices are used has also become diversified and complicated. It is precisely because of changes in the external environment that the industrial control box has become a newcomer to the device core.

 
The industrial control box, also known as the industrial control computer, which is the industrial control computer, is a general term for tools that use the bus structure to detect and control the production process, electromechanical equipment and process equipment. The industrial control box includes the computer motherboard, CPU, hard disk, memory, peripherals and interfaces, and has an operating system, control network and protocol, computing power, friendly human-machine interface and so on. The main reason why industrial control boxes are favored by smart display devices lies in several advantages:

 
1. Strong environmental adaptability

The smart display devices of retail and self-service are mostly in an open environment or semi-outdoor environment, with severe electromagnetic interference, and also need to face harsh environments such as high and low temperature, rain, etc., and are basically in a 24-hour standby state, so the hardware is reliable. Sexual requirements are higher, must be dust-proof, moisture-proof, shock-proof, radiation-proof, and better electromagnetic compatibility and high anti-interference ability.

 
Ordinary embedded motherboards are inferior to industrial control boxes in terms of environmental adaptability. Take Mitsubishi's IoTbox series industrial control box as an example, using a full metal casing, which can effectively prevent dust, shock, interference, radiation, and adaptability. A variety of complex use environments, and effectively extend the life of the motherboard, which is also increasingly the wisdom of display devices
 
 
2, easy to install and maintain
Many IoT smart terminals have a long service life. Even the devices manufactured 20 years ago are still running. This requires enterprises to continuously maintain and upgrade the devices, such as patch updates, to ensure the firmware on all IoT devices. Update to the latest version to protect your device from cyber attacks.

 
 
The one-piece construction is a major advantage of the industrial control box. It does not need to be assembled. It adopts the VISA international universal interface installation standard and is plug and play. Using the industrial control box as the core, the equipment maintenance and upgrade will be more convenient and quicker. No need to disassemble the machine, and directly take out the industrial control box to complete the maintenance and upgrade work.
 
3, high performance and low power consumption
The smart display terminal is unattended and runs at 7*24 hours, so the requirements for the core hardware platform are very high, requiring not only strong performance, but also lower power consumption. In this regard, Rockchip's RK3288 and RK3399 processors, known for their high performance and low power consumption, are the first choice.

 
Take the high-end IoTbox-3288M as an example. The core of the RK3288 Cortex-A17 quad-core processor, dual-instruction decoding, dual address generator (AGU), multi-issue (multi issue) and other special architecture design, instruction execution The efficiency is very high, the frequency is up to 1.8 GHz, and the performance is greatly improved. The GPU is Mali-T764, which is a third-generation Midgard architecture with up to 8 shader cores. It really supports 4K and H.265 hard decoding. Compared with H.264, it saves half the bandwidth and meets the system. Dual requirements for stability and energy efficiency.
 
4, deep personalization
Thanks to the base plate + CPU card structure, the industrial control box has a strong input and output function, can expand multiple functional modules, and support a variety of peripheral expansion to complete various tasks. Ordinary industrial computer has always had the problem of small capacity of the hard disk. According to Mattel's IotBox series industrial control box, RAM and ROM can be configured as needed, thus solving this problem. Based on ARM+Android, the IotBox series industrial control box has a strong openness, supports Android system customization, provides system call interface API reference code, and supports client upper-layer application APP development.

 
5, support AI module
 
Artificial intelligence has developed rapidly, and face recognition technologies in various fields such as security and retail have been successfully put into practical use. The industrial control box equipped with the AI chip can support the intelligent display device to call the AI SDK to realize emerging technologies including face recognition.

 
 
With the continuous iterative evolution of smart display devices, the core shift from embedded motherboards to industrial control boxes has become an important development trend, and industrial control boxes will gradually be applied to more types of self-service terminal devices, including retail self-service terminals, game entertainment terminals, Educational touch terminals, government service terminals, public service terminals, and robotic devices have the core advantages of providing users with more stable, lower-cost, faster, and smoother performance, and improving the experience of terminal products.
