Abstract

The invention develops a water quality pH value intelligent transfer device for intensive water quality monitoring applications, aiming at the status quo of urgent need of automatic water quality monitoring technique in intensive aquaculture in China. The intelligent transfer device integrates the water quality parameter signal conditioning technique and the transfer technique, and is directly input with signals of water temperature and pH value sensor probes, and is embedded with a high performance microprocessor, the device utilizes the self-calibration technique to realize the pH value automatic temperature compensation function on the basis of signal acquisition of probes, and also adopts an intelligent network interface model described in the IEEE1451 standard to realize the self-diagnosis and plug-and-play functions of an intelligent transmitter. The water quality pH transfer device is advanced to develop towards intelligence, networking and miniaturization, thereby raising the water quality monitoring level of intensive aquaculture.

Description

technical field [0001] The invention relates to an intelligent water quality and pH value transmitter, in particular to a networked intelligent transmitter for water quality and pH in intensive aquaculture. Background technique [0002] The pH value is an important electrochemical parameter to reflect the properties of the aqueous solution, and the temperature has a crucial influence on the pH value. Therefore, it is of great theoretical and practical significance to monitor and control the water quality parameters that affect the normal progress of the water environment. [0003] Due to the late start of online automatic water quality monitoring technology in my country, in actual work, a large number of monitoring methods are still traditional laboratory manual analysis methods, and the test data lags behind for several hours or even more. The monitoring instruments used in the water quality automatic monitoring system are mainly traditional two-wire transmitters. At pre...
