[The embodiment] The present invention will be explained by the following embodiments. If they are fully understood, the person skilled in the art can complete it, but the implementation of this case is limited to its implementation. , the implementation of the case

First of all, please refer to (4)-_), which is not intended for the case. The system 10 includes a tank U having a liquid (1) inside, and a light-emitting device m, 132 is disposed on each of the opposite walls of the tank 11, and a laser beam 1311, 1321 of different wavelengths is incident thereon. Inside the liquid U1. The type of the light-emitting device m, 132 on the base I is not limited, and the use of the radiation device in the present invention is only a preferred embodiment, and is not limited thereto. The outside of the tank body n is provided with a discharge structure 14 including a discharge port 140 and a movable cover 141 and a light-emitting device 133. The light source 1331 emitting a fixed wavelength illuminates the movable cover 141, and a side cover is provided thereon. The first image sensing device 121 is provided with a second image sensing device 122. The first and second image sensing devices 121 and 122 can be a network camera, or can be any A device that captures or recognizes images. As can be seen from the first figure (8), each component 'in the present system 10' includes the light-emitting device 13 132 and the first and second image sensing devices 12 122, etc., which are not in direct contact with the liquid U1, and thus are basically Effectively reduce the maintenance cost of the device. The first image sensing device 121 is configured to recognize a horizontal distance when the movable cover 141 is opened and a corresponding vertical distance, as shown in the first figure (b). For example, when the movable cover 141 is opened, the first horizontal distance dl is displayed from the closed state, and a first vertical distance corresponding to the first horizontal distance dl is hi'. The movable cover 141 and the discharge opening 201124711 are the opening 1 θ]. In the present invention, the discharge port 14 is a horizontal check valve. When the discharge is reversed, the volume of the liquid 111 in the tank 11 has exceeded the reverse pinning force provided between the levels. The 1 force will squeeze the financial body to the outside, and, 'this, the current flow of the liquid and the entanglement of the outlet will also be corrected, and the opening angle of the opening cover 141 is different. Basically, the first image sensing device 121 in the present invention senses the horizontal distance and the vertical distance by using the light-emitting device 133 to illuminate the movable cover 141 when the movable cover 1_41 is activated. The light shirt changes in color and the horizontal distance and the vertical distance are obtained by analyzing the difference in light before and after. However, it is of course not limited to the use of changes in light to achieve these distance changes, which is merely a preferred embodiment. Therefore, the first image sensing device 121 senses the first, second or third horizontal distance between the movable cover 141 and the discharge opening 14 at different points in time (Π, d2, d3, and the corresponding corresponding portions thereof) a second or third vertical distance Μ, h], ^, and these parameters are transmitted to an arithmetic device 15. Using the principle of a trigonometric function, the first, second or third angle θ ι can be obtained separately. The value of the formula is as follows: knife Θ - tan-1 — h Equation (1) If multiple angles are recorded, different angles corresponding to different flow rates are recorded as shown in the second figure, then a linear first Relationship: where the χ coordinates are the amount of water, the unit is cubic meters per 曰 (CMD); the y coordinate is the angle. The first relationship is y=〇.2898x+4.8199 'where the R square value is 0.9752, the relationship can be seen The formula is very close to the actual value. Therefore, after the first relationship is established, if the first image sensing device 121 detects an arbitrary horizontal distance, such as a corresponding vertical distance, After the angle is 0 „, the first relation can be directly applied to obtain In addition, as shown in the second figure, the second image sensing device i22 senses the distance 16' between the two spots of the two laser rays 13U and 1321 when the person is (1). The change in intensity exhibited by the light 1311, i32i when entering the liquid (1) is also a specific range 17.

Due to the special position of the t-lighting device 13 of the present invention, the light rays 13U, 1 are not at right angles when the liquid level is cut. If the water level changes, the spacing 16 between the two light spots on the liquid surface will correspond accordingly. The emergence of changes. By sensing the second image, the current water level can be obtained by sensing the distance between j and m at any time and the liquid level. Therefore, if different distances corresponding to different waters (4) are used at different times, the different distances of the first-shirt-like sensing device 122 and the liquid-off are transmitted to the -Xian operation money 15 as the fourth figure. As shown, a linear second relationship can be obtained. Its towel X coordinate is the image towel two light ‘off distance _ number, the unit is! / Pixel (4) S); The y coordinate is the actual water level height in centimeters (four). The second relation ^ 1345.1x+44.459, wherein the R square value is α9973, the relationship can also be seen, and the actual values are very close. Therefore, after the second relationship is established, if the second image: 122 detects an arbitrary interval, the grain cover uses the second relationship to obtain the water level. When the light enters the liquid towel, it will have the intensity attenuation and change due to the different concentrations of suspended solids (SS) contained in the water. Therefore, the difference between the liquid and the different effects of the liquid at different concentrations is related to the poor water quality. The change in the intensity of the light can be reflected by its change in the color of the liquid. (4) The intensity of the light is not only obtained from its color, but in any way it can be made into the towel of the present invention, here only - Better example 201124711 Example. Therefore, when the second image sensing device 122 senses a certain range of light in the liquid, it records and transmits the color value (RGB value) of the light to the arithmetic device 15. The so-called RGB values are three values between 〇 255, which define all colors in nature and medium. After the computing device 15 receives the sensing information transmitted by the second image sensing device 122, it calculates the RGB spread of the light per unit cube of the rib rib, that is, calculates and averages the three health balances. - Grayscale value G 'The grayscale value G represents the intensity of the light in a particular unit cube. That is to say, if the light ray 13 Π is taken as an example, if the fiber 19 is displaced from the liquid level into the liquid 111 and is completely attenuated in the liquid 111, the light ray 131 丨 in these units. There will be 1G grayscale values G1-G10. For the same liquid, the penetration rate (τ) is this =, Τ 1) 'which is the first gray scale value divided by the first ^ should be specific to the second penetration value (Τ 2), which is The second gray scale value is divided by (10) three gray scale values (G2/G3). However, the theoretical value will have some errors, so the average penetration rate is calculated based on the 10 gray scales: the TW9 force is averaged to obtain a :=^(T_age). And can be mixed with the average pure Bobo (four) luminosity (4), equation (2) A = l〇g1 Therefore 4 under the premise of the same water sample, the calculated absorbance value spot sampling and the standard detection method published by the Environmental Protection Agency The % concentration obtained is compared, ie, the --stable value. ___ 201124711 Obtain a linear third relation, as shown in the fifth figure (4), which is r, light..., shot 'for the secondary settling tank, the discharge water ss concentration and the red light absorbance off β,, where X coordinates The SS concentration is in milligrams per liter (mg/L); the y coordinate is the absorbance. The third relation is y=0.0021x+0.105., where the R-squared value is 0:863, and it can be seen that the relationship is very close to the actual value. On the other hand, the other light uses the green light of different wavelengths to illuminate the same secondary settling tank, and the number of records can be obtained to obtain a linear fourth relation, as shown in the fifth figure (8), which is utilized. 4 light,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The fourth relation is y = 〇〇(8)4χ+〇〇191, where the R-squared value is 0.8265, although this value is not as high as the R-squared value obtained under red light illumination, but the two are still very close. Therefore, after the third and fourth relational expressions are established, if the second image sensing device 122 detects an arbitrary RGB RGB value, the absorbance can be directly calculated after calculation and applied according to which light. The third or fourth relationship is used to obtain the water quality SS concentration. However, for water bodies with different pollution characteristics, it is not fixed to use red light or green light. Therefore, in the present invention, water is set by simultaneously setting two different wavelengths of laser light to obtain water quality information. Can greatly increase the scope of application 'In the future, it can also increase the use of different wavelengths of laser light source to improve accuracy. Next, please refer to the sixth figure, which is a flow chart of the water quality and quantity monitoring method proposed by the present invention. Firstly, the device is erected around the trough (step S61), that is, an image sensing device is disposed above the trough body and on the side of the movable cover of the discharge port, and two light-emitting devices are arranged on the inner wall of the trough and above the water surface. The laser light of two different wavelengths is respectively irradiated into the water body. Another light-emitting device is disposed on the side of the movable cover to emit a fixed-wavelength light source to the movable cover according to 201124711. Then, the image sensing device is used to capture the image (step S62). That is, an image sensing device positioned beside the movable cover is used to sense the change of the light image caused by the illumination of the light source when the movable cover is opened with the liquid discharged. Obtaining a water distance from the discharge port and a corresponding vertical distance; and sensing the distance between the two spots of the two laser rays on the liquid surface and the two laser rays by using another image sensing device located above the groove body The change in intensity after injection into a body of water, that is, the change in color value. Then, the data sensed by each image sensing device is transmitted to an arithmetic unit for calculation and processing (step S63). At this time, the computing device calculates the angle of the lost angle between the movable cover and the discharge port according to the detected horizontal 钃 distance and the vertical distance, and the angle reflects the current flow rate, or can be said to be the tank body. The amount of water inside; and the nose device also calculates the grayscale value in the unit cube of the liquid according to the measured color value change, and calculates the average transmittance according to the grayscale value, and then the liquid is obtained. The absorbance of each laser light. Use these detected information and the obtained parameters (including estimated angle, spot spacing, absorbance) and then cooperate with known conditions or parameters (including recording different flow rates for different opening angles of the movable cover, in different liquids A second image sensing device and a liquid-to-surface distance, and a liquid ss concentration value obtained by a standard detection method) can be used to create a database (step _. The database includes various relationships established, For example, the relationship between the amount of water and the angle of the cool angle mentioned above, the relationship between the spot distance and the actual water level of the liquid, and the relationship between the specific light absorbance and the water quality ss concentration, etc., when the database is established, if the first image sensing is compared And detecting any information with the second image sensing device, and transmitting the information to the computing device to calculate, for example, the angle, the spacing 12 201124711, the value is calculated, S65)
