Intelligent water quality monitoring system and method

The invention relates to a smart water quality monitoring system and method, in particular to a monitoring technology for automatically monitoring the water quality condition to be tested.

Whether it is seawater, freshwater aquaculture water to be tested or aquarium, it is necessary to regularly check the ammonia content in the water to avoid a large number of deaths of aquatic organisms due to high ammonia content. According to the conventional method for detecting the water content of ammonia, the water quality test paper for detecting ammonia is immersed in water for about 1 to 15 minutes, and the color change of the water test paper is observed by the naked eye. When the color of the water test paper turns blue, it means that the ammonia content in the water is too high, so it must be changed immediately or other corresponding treatment; on the contrary, when the color of the water test paper is light yellow, it means that the ammonia content in the water is biased. Low, so there is no need to do water change treatment. Because the human eye is inevitably affected by climate or health factors (such as color blindness or visual deterioration), the color recognition is often caused by the color recognition error; not only that, when the water location to be tested or the number of aquariums When it is added, monitoring the water quality by manpower will indeed cost a lot of manpower and time costs.

Wu. The present invention is specifically implemented

In the specific operation of the present invention, the cycle time of the water quality detection start must be set in advance, for example, the cycle is set to once a day, and the time can be set to 8 o'clock in the morning (AM). Referring to FIG. 11, when the set cycle time is reached, the signal processing unit 22 triggers a driving circuit (not shown in the figure), thereby starting the motor 131 to operate in one direction, and the reel 132 is subjected to the motor. The rotation of the 131 is gradually rolled away from the cable 134, so that the cable 134 moves around the reel 133 and pulls the casing 12 downward. When the conveyor belt 14 in the casing 12 is immersed in the water, the signal processing unit 22 transmits The positioning sensor of the positioning sensor (not shown in the figure) stops the motor 131 for a period of time (about 1 to 15 minutes); as shown in FIG. 10, when the motor 131 stops operating, the signal processing unit 22, the drive circuit is triggered again to start the motor 131 to run in the other direction. At this time, the reel 132 is rotated by the motor 131 to take up the cable 134 in the other direction, so that the cable 134 is pulled around the reel 133. The housing 12 is moved upward. When the housing 12 reaches the top dead center position, the signal processing unit 22 stops the operation of the motor 131 through the positioning sensing of another positioning sensor (not shown in the example). At the same time, the driving member 113 (such as the stepping motor) of the test paper conveying mechanism 11 is activated by the trigger of the signal processing unit 22. When the driving member 113 drives the first reel 110, the second reel 111 can be rotated coaxially, so that the portion of the conveyor belt 14 immersed in the water can be displaced upward through the pulley 112 to the slot 122 of the first end of the housing 12. The color sensing module 21 is located at the position, and the white sensing element 25 is provided on both sides of the color sensing module 21 as a fill light or white balance compensation. Group 21 can then sense the color of the conveyor belt 14 to produce a sensing signal.

Corresponding color identification data and a water quality information corresponding to the color identification data, and when the water quality information exceeds a predetermined value, the signal processing unit 22 determines that the color identification data is abnormal, and outputs a control signal to trigger the color recognition device. The prompting module 24 of 20 outputs a warning signal of abnormal sound or light of water quality, which can be output through the alarm; or the display shows the water quality information of the water to be tested. In addition, it should be noted that an opening 120 is defined in the end surface of the second end of the housing 12, and a through hole 121 is formed in the surrounding wall surface, and water can enter the second end of the housing 12.

Lu. Principle and implementation of color identification of the present invention

The color sensing module 21 in the experimental example of the present invention uses a TCS240 color sensor. The TCS240 color sensor dynamically selects the desired filter through two programmable pins. Typical output frequencies range from 2Hz to 500kHz and can be selected from 100%, 10% or 2 via two programmable pins. % output scale factor, or power down mode. For example, when using a low speed frequency counter, a small scaling value can be selected to match the output frequency of the TCS240 color sensor to the counter. As can be seen from the figure, when the incident light is projected onto the TCS240 color sensor, different filters can be selected by the different combinations of the photodiode control pins S2 and S3; the current is output to the frequency converter and the different frequencies are output. Wave (duty cycle is 50%), different colors and light intensity correspond to square waves of different frequencies; you can also adjust the output frequency range by outputting scaling control pins S0 and S1 to select different output scaling factors. Adapt to different needs. S0, S1 are used to select the output scale factor or power-off mode; S2, S3 are used to select the type of filter; OE is the frequency output enable pin, which can control the state of the output when there are multiple chip pins shared When the output pin of the microprocessor is used, it can also be used as a chip select signal. OUT is the frequency output pin, GND is the ground pin of the chip, and VCC provides the working voltage for the chip.

Furthermore, it is known from the principle of three primary colors that if you know the three original colors that make up the various colors The color value, you can know the color tested. For the TCS240 color sensor, when a color filter is selected, it only allows a certain primary color to pass, preventing the passage of other primary colors. For example, when the red filter is selected, only red can pass through the incident light, blue and green are blocked, so the light intensity of the red light should be obtained. At the same time, other filters can be selected to obtain blue light and green. The light intensity of light. With these three values, the color of the light projected onto the TCS240 color sensor can be analyzed.

In theory, white is a mixture of equal amounts of red, green, and blue; in reality, the three primary colors in white are not exactly equal, and for the TCS240 color sensor, for three basic colors. The sensitivities are not the same, resulting in RGB outputs of the TCS240 color sensor are not equal.

Therefore, in the experimental example of the present invention, white balance adjustment is performed before the test, so that the TCS240 color sensor is equal to the three primary colors in the detected "white". The white balance adjustment of the present invention is prepared for subsequent color recognition. The actual operation mode is to place an empty test tube above the TCS240 color sensor, and place a white light source above the test tube so that the incident light can pass through the test tube and illuminate the TCS240 color sensor, and then strobe red. The green, blue, and blue filters measure the red, green, and blue values, respectively, and then calculate the three adjustment parameters needed. When the TCS240 color sensor recognizes the color, the three parameters are used to adjust the parameters of the measured colors R, G, and B. There are two ways to calculate adjustment parameters. As shown in FIG. 6, it is a schematic diagram of the color capturing control steps of the module of the present invention. A method for adjusting parameters is to sequentially strobe a three-color filter, and then sequentially count the output pulses of the TCS240 color sensor. When counting to 255, the counting is stopped, and the time used for each channel is calculated separately. These times correspond to the time reference adopted by each filter of the TCS240 color sensor during the actual test, and the number of pulses measured during this period of time. It is the corresponding value of R, G and B. Another way to adjust the parameters is to set the timer to a fixed time (example) For example, 10ms), then strobe the filter of three colors, calculate the number of output pulses of the TCS240 color sensor during this time, and calculate a scale factor. By this scale factor, the number of these pulses can be changed to 255.

In the actual test, the same time is counted outdoors, and the measured pulse number is multiplied by the obtained scale factor, and then the corresponding values of R, G, and B are obtained. In order to establish a database and evaluate the feasibility of the present invention, the inventors conducted detailed experiments in detail. First, add 1 liter of pure water into 1CC concentrated ammonia water, and adjust the ammonia water of about 1000PPM concentration. Then take the ammonia water out of 1CC and add it to the measured basic value of 1 liter of seawater to transfer about 1PPM of ammonia seawater. 1 PPM of ammonia seawater 1CC, 2CC and 5CC were respectively added to 10CC seawater to respectively transfer about 0.1 PPM, 0.2 PPM and 0.5 PPM of ammonia seawater. Use a metal clip to clamp a piece of test paper into the test tray and fill it with the above-mentioned concentrations of ammonia seawater for seven minutes, then use the color comparison table to compare the colors close to it, then clip the test paper out and place the background black plate. Then use the color sensing device to aim at the center distance. The environment is all black (only by the system fill light). The (RGB) values are (60.63.42) (0.1PPM) and (52.51.40) (0.2PPM). (40.41.40) (0.5PPM) and (36.35.43) (1PPM), the (RGB) value of 0PPM is (68.68.48). From the experimental results, we can find that the first two values change almost the same. You can use the color classification. The third value has almost no change, so you can't classify it. We use a simple way to classify the data in a single wafer. Two values below 68 are classified as 0.1 PPM, and when RG is lower than 60, they are classified as 0.2 PPM. When both values of RG are lower than 52, they are classified as 0.5 PPM. When RG is lower than 40, the classification is 1 PPM. When less than 36, it is classified as greater than 1 PPM. It can be seen from the experimental results that this method is more objective and feasible than the naked eye.
