Electrochemical analyzer with wireless transmission function

Abstract

The invention discloses an electrochemical analyzer with wireless transmission function, which is used for connecting equipment with wireless transmission function such as a computer and executing electrochemical signal collection, transmission and treatment. The electrochemical analyzer comprises an electrode control unit, a data collector, a processor, a wireless transmission module, a signal generator and a power supply module. The analyzer can independently operate when the computer connected therewith is turned off or the connection is disconnected and store the collected data in a memory of the analyzer, and the stored data can be updated when the connection is reestablished. The analyzer can be used for remote continuous monitoring of waste water and gas and for electrochemical analysis and detection in harmful environments such toxic, high-temperature and radiation environment. Specifically, the analyzer can be used in combination with miniature electrochemical sensor to construct a miniature electrochemical data wireless collection system or disposed in other instrument or equipment for adding electrochemical analysis and detection function therefor.

Description

technical field [0001] The invention relates to an electrochemical analyzer, in particular to an electrochemical analyzer with wireless transmission function. Background technique [0002] At present, many electrochemical analyzers are connected to computers through GPIB, RS232, USB and other interfaces for data transmission. For example, Model-273 electrochemical system of EG&G Company adopts GPIB interface, a GPIB communication card should be installed in the computer, and the instrument is connected through GPIB cable, so the circuit is complicated. The CHI6 series electrochemical workstation of CHI Company adopts RS232 interface to exchange data with the computer, and the instrument and the computer are connected through the RS232 serial communication line. The OMNI90 series electrochemical system of Cypress Company adopts the method of analog signal transmission, and transmits the analog signal of the instrument to the data acquisition card installed in the computer th...

AI Technical Summary

Problems solved by technology

[0004] 1. The instrument is large in size, which is not conducive to carrying it around when going out

[0005] 2. The instrument needs AC power supply and cannot be used in places without AC power supply

[0006] 3. The instrument must be connected to the computer through a connection line, which is not only complicated in the connection relationship, but also not conducive to the development of the instrument to miniaturization

[0007] 4. The data transmission distance is short, and the instrument needs to be installed close to the computer and the operator. It is not suitable for toxic, high temperature, radiation and other harmful environments and unattended remote monitoring applications
