Specific embodiment
With specific embodiment, explanation is further explained to the present invention below in conjunction with the accompanying drawings.
A kind of present invention discrete cultivation water detection method, it comprises the following steps：Step S1：Monitored foster at each
Grow the other install sensor in field and data acquisition and Transmission system, data acquisition is detected with Transmission system reception and analyte sensors
Water quality information；Step S2：Data acquisition is coupled with the oxygen system of culturing pool and feeding feeding system with Transmission system；Oxygen supply system
System and feeding are fed and are carried out automatic oxygen supply and feeding according to data acquisition and Transmission system analysis result；Step S3：Each number of units
All ModbusTCP protocol data, access industrial LAN are changed into by Modbus modular converter according to collection and Transmission system；Step
S4：Microhabitat detection platform extracts detection water quality data by DTU, by this data storage in data server, then counting statistics
This data, user or staff check current detection data and 24 hours tendency charts by PDA.
Further, described sensor includes temperature sensor, dissolved oxygen sensor and liquid level sensor；Described temperature
Sensor adopts Pt100；Described dissolved oxygen sensor is based on embrane method and measures；Described liquid level sensor is based on pressure detecting principle,
It is arranged on culturing pool bottom, measures the pressure to sensor diaphragm for the water body, conversion obtains water height.
Further, described data acquisition is connected with digital display pick-up instrument with Transmission system；Described digital display pick-up instrument is used
In realization display water quality information.
Further, also bag alarming step in described step S4：User or work after detection data exceeds monitoring index
Personnel receive alarm.Monitoring index requires according to fish growth characteristic and breeding environment, balance quality, cost, use
Convenient degree and maintenance requirement select.
The water quality monitoring index of breeding water body is more, contains the depth of water, water temperature, water colour, turbidity, floating thing, dissolved oxygen rate, acid
Basicity, electrical conductivity, oxidation-reduction potential, salinity, ammonia nitrogen, nitrate, chlorion, COD, BOD and concentration of metal ions etc..
In the specific embodiment of the invention, the design requirement of the circulating water cultivation factory according to fishing small stream, have chosen part index number
And monitoring method, establish following monitoring scheme：
From the depth of water, water temperature, dissolved oxygen, acid-base value, electrical conductivity, ammonia nitrogen, nitrate nitrogen, cultured water etc. as Testing index, by
In fishpond, change of water quality is more slow, and the monitoring cycle of part water quality index can lengthen to a few hours, can using vacuum drawn and
Centralized monitoring system, to reduce the expense of sensor and data acquisition and Transmission system.But, water temperature, the depth of water and dissolved oxygen with
Cultivation has substantial connection, belongs to call parameter；According to vacuum drawn and centralized detecting method, these desired values can occur very big
