Biological toxicity analyzer, biological toxicity analyzer, water quality toxicity warning system - [BS-2015]Imported from Japan

Biological toxicity analyzer, biological toxicity analyzer, water quality toxicity warning system - [BS-2015] Introduction:

The water quality biotoxicity warning and monitoring system is an on-site automatic water quality monitoring laboratory established in river basins, lakes, reservoirs, drinking water sources, groundwater observation points, nearshore waters, and other areas. This system is mainly used for continuously and automatically monitoring the water quality changes of the tested water body, objectively recording the water quality status, timely detecting water quality abnormalities, and then warning the water quality situation of the water area, predicting the water quality situation of downstream water areas, and effectively preventing water pollution accidents.

Biological toxicity analyzer, biological toxicity analyzer, water quality toxicity warning system - [BS-2015]Advantage: The biological warning is intuitive and visible, and can warn of both single toxicity and comprehensive toxicity. Real time assessment of water quality toxicity through comprehensive image analysis.

The biotoxicity analyzer, biotoxicity analyzer, and water quality toxicity warning system (BS-2015) are devices used to monitor the water quality of rivers and lakes, as well as the safety of household and factory drainage, using medaka fish. The device adopts the latest image processing and IT technology, with an electronic collector that observes the movement of 12 blue catfish swimming in the water tank that introduces raw water into the waterway 24 hours a day. When the movement of the medaka becomes sluggish or stops, there is a possibility of toxicity in the water, and the instrument will automatically notify the staff.

This method is used to determine the activity level of the medaka fish and analyze and judge the activity level. The instrument performs multiple measurements per second, transmits the measured values to the computer, calculates the 3-minute, 1-hour, and 24-hour moving averages, and presents them in a chart. At the same time, the instrument will analyze and compare the 3-minute, 1-hour average with the 24-hour average. Send an attention signal when the 3-minute moving average is below 50% of the 24-hour average, and send an abnormal alarm signal when it is below 30%. The setting of the alarm limit can also be changed. Save the measured activity levels, images, and status changes, and label them with a time and date, which can be used as a reference for recording. The instrument will save images in "timed", "attention", and "abnormal" states.
Use 5760 electronic eye monitoring points in the experimental setup to detect the activity of fish. Measure the total number of monitoring points (activity level) that detect fish activity with approximately 7 brightness changes per second, convert the measured values into a moving average suitable for inferring the trend of change, and send an alarm when the preset value is reached.

Biological toxicity analyzer, biological toxicity analyzer, water quality toxicity warning system - [BS-2015] Monitoring method:

open up or clear out by poking or jabbingThe method of analyzing and determining changes in water quality by monitoring two aspects of data on the activity of medaka fish: activity level and simulated survival rate.

Monitoring time: Measure each time0.5Once every second, transmit the measured value to the built-in computer and calculate it 3Minutes24 The hourly moving average is represented by curves and numerical values.

Status classification:'Madness',' Attention ',' Abnormality '

Monitoring data setting method:

Biological toxicity analyzer, biological toxicity analyzer, water quality toxicity warning system - [BS-2015] Judgment method:

equal3 The average activity level per minute exceeds its benchmark value (based on experience, the benchmark activity level value is set as20 ）At this time, a 'frenzy' signal will appear. support 3 The number of simulated surviving entries per minute and its correlation 24 Compared to the hourly average (benchmark value), when 3 The minute moving average is lower than its 50% When a 'Attention' signal appears,

below25% Appear and send an 'abnormal' alert.

The "Attention" and "Madness" signals are used as reference states. When an "abnormal" alarm occurs, there is a possibility of a water source pollution accident. The water sample in the automatic sampling device of the instrument should be sent for testing in a timely manner.

Data saving:

Save the activity level, simulated survival count, images, and status changes, and label them with time and date, which can be used as a reference for recording. The image is'Timing', 'Madness' Saved in "Attention" and "Exception" states.
