Paperless recorders are at a critical historical turning point. Paperless technologies such as data acquisition systems and paperless recorders are challenging existing data collection methods. The task-based recorder can capture and display process flow data and then save it in an electronic record that can be imported into a PC environment. The relevant batch data information can be saved in a single secure data file that can be archived and recalled as required. Paper recorders are not expected to be accurate, efficient and safe.
I remember using the [paper recorder] in 70 and 80 years, using a pneumatic and electric paper recorder produced by the factory. I went to work every day to check the paper roll with red and blue ink, ink bottle. The soft plastic tube was inserted into the line of the pointer, and the red blue on the hand was very difficult. Later, the pen with ink was designed. There are 2, 4, and 6 channels, and the recording paper is archived, and the overall cost is high.
Paperless recorders have developed paperless recorders in the past decade. In recent years, they have developed rapidly, widely used, powerful, and applied in the industry. Paperless recorders significantly reduce the cost of the user. These devices have a fixed structure, meaning that there are no mechanical parts that need to be monitored or maintained. There is no additional cost (such as adding charts and pens).
The paperless recorder is constantly evolving, and Yudian has created a split-type paperless recorder that uses the combination of true color human-machine interface touch screen and smart meter: there is a true color real-time curve display, and the lower meter can also display the number at the same time. Retain the operation function of the instrument, display AI-2070S split paperless recorder with rich information and industrial control product elements.
Second, the development trend of paperless recorders, innovative applications [true color man-machine interface touch screen] set up Yudian [true color man-machine interface touch screen + smart meter combination of split paperless recorder] completely changed the paperless recorder Structure has entered the category of computer applications.
It is based on the AI â€‹â€‹series instrument to add a real color human-machine interface touch screen, which realizes the centralized display operation and the paperless recorder function, and the system appearance is higher. The photoelectrically isolated RS485 communication interface between the meter and the touch screen does not affect the touch screen and other instruments. The touch screen faulty instrument can still be used normally, that is, respecting the tradition and leading the trend, and conforming to the industrial control of â€œconcentrated operation and dangerous dispersionâ€ Product design requirements.
The development of paperless recorders has gone through an extraordinary road, which is directly connected to the LCD screen from analog signals: integrated LCD panel instrument, which has complex structure and is susceptible to on-site interference. It is more fragile such as industrial control lines and civil LCD screens. Complex circuit design in a casing, its safety standards, anti-interference, temperature range and other issues are likely to cause quality instability, once the fault or due to interference crashes, often cause multiple circuits to lose control at the same time, bringing catastrophic consequences to the site , Yudian has discontinued the product.
[The true color man-machine interface touch screen + smart meter combination split-type paperless recorder] concentrates the advantages of the traditional paperless recorder, improves the reliability, easy to grasp between each measurement control point, fault isolation, and man-machine The faults between the touch screen recorders are isolated from each other and do not affect each other and spread. The fault of the human-machine touch screen recorder only affects the functions of centralized management and data recording, and the measurement point signal can still maintain the normal control and operation. [Split-type human-machine interface touch screen + smart meter combined split-type paperless recorder] The display content on the touch screen recorder screen is rich, and the measured value, given value, output value and instrument label can be displayed at the same time. The set value, program recipe and common parameters can be modified by the human-machine touch screen recorder.
The addition of the flow chart uses a vivid graphic picture to describe the on-site production process, which is the epitome of the entire industrial site. It is more than just a picture, it visually displays real-time data from industrial sites, giving operators a very intuitive remote control. Connect AI-3013D5 switch 8-way relay output module, the address is set to 33, the switch button in the figure can control 4 sets of motor start and stop; high-performance recording function, based on personal computer system, while applying low-cost paperless recorder Its performance (recording density, recordable time and easy to find) is much higher than various paperless recorders. The detailed function screen is more user-friendly.
[The true-color human-machine interface touch screen + smart meter combined split-type paperless recorder] its function surpasses the traditional paper recorder and other electronic data recording system, thus effectively meeting the development trend of this important market segment. .
