The front-end signal detection, timely data collection, data processing, optical electromechanical integrated automatic device to achieve its functions, as well as the human-machine operation interface, must also have a complete control program software package for the upper and lower computers. To achieve the performance of the above aspects, embedded single board computers based on high-performance microprocessors seem to have become the only choice for instrument design so far.

Thus, after the specific performance requirements of the instrument are determined, the design and manufacturing of software and hardware for single board computers will enter the agenda. This job is very professional and extensive, and relatively small companies cannot reserve so many professional and technical personnel, so relying on their own technical strength is impossible to complete. To achieve this, it is necessary to pay high design and development costs, and the joint debugging of the entire machine’s software, hardware, and external devices also requires a lot of time, rework, and redesign. Similarly, large companies are not without similar problems. Especially in the prototype trial production stage of exploring and innovating new technologies and methods.

 

The concept of the so-called new solution stems from personal professional technical experience and exposure to different technical fields. The author has worked in the fields of precision instrument design and industrial automation, respectively. PLC technology, especially the performance of the domestic HOLLiAS LM series small PLCs, provides me with a technical space to re-examine precision instrument design solutions.

From the perspective of design methodology, there is no regulation in the world that automatic instruments must be based on a single board computer. As long as they can achieve instrument design that is inclined towards user requirements, it is a successful product. In other words, users and users do not care about the design process and internal structure of the instrument, they only care about the performance price ratio of the instrument. As designers, what we need to consider is all design solutions, means, and technical approaches that can achieve the expected performance, which is more in line with the thinking methods and design procedures of design methodology.

Considering technical feasibility, let’s first take a look at the hardware requirements for electronic control. Generally, the system needs to have a high-performance CPU, a certain amount of memory, DI, DO, AI, AO, communication ports with the human-machine interface, and a program developed according to specific operational requirements. These tasks are equivalent to developing a specialized small operating system for a single board computer or DSP system. In terms of hardware, it is often necessary to design a PCB board for a single board computer or DSP. In today’s SMT technology, designing and improving such a system is not an easy task. Debugging issues go without saying, and even one or two DI extensions require redesigning and modifying the PCB board.
