Problems solved by technology

[0002] The current analytical instruments mostly stay in the stage of single measurement, calculation, display, printing and short-distance wired output, and cannot remotely analyze and process data. Although some instruments adopt technologies such as data remote transmission interfaces, they can transmit data over a limited distance. However, data communication basically adopts traditional converters, such as RS232 or RS485, so there are defects that communication must be wired, the distance is short (RS232 is tens of meters, RS485 is at most hundreds of meters), the reliability of data is poor, and the wiring construction Difficulty, expansion and upgrade functions are not strong, and the cost is too high
Another example is infrared transmission, which has strong directionality and is not convenient for function expansion.
[0003] Moreover, even if the existing instruments can be transmitted remotely through the network, due to the unstable network signal, it will cause transmission problems
