Paperless recorder of the historical evolution

With the computer hardware and software technology to promote the development of the software configuration, communication protocol standards in the formulation, RS485 communication bus applications. The emergence of touch-screen tablet PC, the system architecture of diversity there.
 
The form of a new generation of communication bus appeared paperless recorder. As the rapid development of touch-screen tablet PC and hardware vendors designed embedded hardware technologies, Microsoft WINCE operating system, colorful LCD touch screen, the reliability of the system itself is guaranteed, fast constitute a high-performance human-machine interface.

Recorder's development for decades, as an important data logging instruments, has been widely used in various industrial field, especially in the field of process control. It is a very commonly used in automated meter secondary instrument is to record data, save the data extremely effective tool.

Throughout the development process recorder, roughly gone through three stages: the traditional mechanical analog gauges, the first generation of paperless recorders and network-based virtualization technology, multi-functional paperless recorder.

Prior to 1995, using essentially mechanical pen and paper recorder, which records by recording pen on paper drawing curves, so as to achieve the purpose of record and save the data. Servo system because of its ability to write complex, mechanical moving parts and more reliability, less so. At the same time there is mechanical recorder display a single (Curve Records), the follow-up data-processing difficulties, the long-term operating costs high (need to be changed regularly recording paper and ink), etc. inherent defects.

In 1992, the International Instrument Exhibition Held in Beijing, the British P & G, German B & H companies were showing a new concept of paperless recorder, internal disciplinary company's keen awareness of this significant market opportunity, carried out an imitation development. In 1997, Anton took the lead to market LU-R / C-series paperless recorder, paperless recorder using microprocessor, liquid crystal display and semiconductor memory, completely overcome the mechanical recorder deficiencies that exist Department, paperless recorder to replace the mechanical recorder has become an indisputable fact.

In the ensuing decade of the development process, paperless recorder market, domestic products accounted for an overwhelming advantage of broad domestic and international products at the same level of technology. Although Honeywell, YOKOGAWA products processes and other foreign companies than domestic products refined, precision ± 1.5 ‰ to ± 2.0 ‰ compared with domestic products better, but four times more than the price of Querang users away. So far the domestic recorder manufacturers up to more than 30, including Xiamen, Andong, SUPCON, Shenyang Lan Shen, Hangzhou Pangu largest. These four accounted for annual sales of similar products in the total domestic sales about 90%.

After nearly a decade of development, the current technical level recorder has been qualitative improvement, improved result is said earlier, the third phase - a network based on virtual technology, multi-functional paperless recorder, showed the following technical characteristics :

l Display: color LCD screen to replace the small monochrome LCD screen;
l Display Technology: a variety of measurements show that the method - curve, bar chart, figures, flow charts;
l I / O channels: universal input module to replace the custom input module, and the extensive use of a little bit of isolation techniques;
l measurement techniques: VF measurement to replace the AD measure (based on cost considerations);
l Network Technology: Network operating mode to replace the stand-alone operating mode;
l storage media: large-capacity FLASH Flash Disk replacement disk;
l Virtual Technology: Virtual instrument technology in the paperless recorder on the widely used - the virtual channel;
l Multi-function: data measurement, Flow Totalizer, rational integration of control functions;

Xiamen Anton successfully developed by LU-R / C series paperless recorder with the above characteristics are the third generation of paperless recorders. Through the color LCD display, able to curve, bar chart, figures show record data and other means, to achieve single-curve / multi-channel curve and bar chart, the choice of display and circulation figures show. In particular, take the paper recording curves analog display, and browse the historical curve of dynamic display, so that LU-R / C series paperless recorder to reach the domestic advanced level.
