Intelligent transmission apparatus for pH value of water

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.
