Analytical instrument system with wireless communication function

Abstract

The application relates to an analytical instrument system with a wireless communication function. The analytical instrument system comprises an upper computer, a lower computer and a server, wherein the upper computer is connected with the lower computer through the server; the lower computer is connected with an analytical instrument; the upper computer is arranged as a terminal with a 3G networking function; a 32-bit ARM system is adopted for the lower computer; the lower computer and the server are connected through a CAN (Controller Area Network) bus, so that 3G wireless network communication is realized. The analytical instrument system provided by the application utilizes a 3G network to realize the data transmission and control with a chemical analytical instrument through the wireless network communication; the 3G network has the advantages of high speed, low cost (selective set service), signal stability, and the like; one terminal is used for operating a plurality of analytical instruments; the 32-bit ARM system and the CAN bus technique are adopted for the lower computer, so that an extended function is achieved; a mature 3G terminal serves as the lower computer, so that signal transmission is relatively stable and reliable.

Description

technical field [0001] The present application relates to an analytical instrument system, especially an analytical instrument system with a wireless communication function. Background technique [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 It is difficult, the expansion and upgrade function is not strong, and the cost is too high. Another example is infrared transmission, which has strong direct...

[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
