Description

[Technical Field]

[0001] This invention relates to the technical field of sensing and monitoring, and more particularly to a liquid hue sensing and monitoring system and method. [Previous Technology]

[0002] Traditional liquid detection methods, such as those using reagents and test strips, involve contacting the liquid to be tested with the reagent or test strip and observing the changes in the reagent or test strip to determine the liquid being tested. Besides cost and environmental issues, these methods have other limitations. They typically require a certain reaction time, which is a significant inconvenience for industrial applications requiring rapid detection. Furthermore, these traditional methods usually require specialized personnel or manpower to perform and may require sample pretreatment, such as filtration or dilution, all of which increase the complexity and time cost of the detection.

[0003] Furthermore, these methods are generally lagging behind in data recording and management, lacking real-time data analysis and early warning capabilities, which is a significant shortcoming in today's data-driven industrial environment. [Summary of the Invention]

This simplifies the detection process and reduces time costs. In other words, the liquid hue sensing and monitoring system and method of this invention support automatic liquid detection, automatically detecting and judging the liquid hue at fixed times. If the system detects an abnormality in the hue of the liquid being tested, it can also provide an immediate alert, unlike traditional detection methods that still require periodic reagent or test strip testing, significantly reducing the user's operating costs.

[0025] In order to facilitate your understanding of the content of the present invention and the effects that can be achieved, the specific embodiments listed in the figures are described in detail below.

[0026] Figure 1 is a schematic diagram of the structure of the liquid hue sensing and monitoring system of the present invention. The liquid hue sensing and monitoring system 100 of the present invention may include a hue sensing module 200 and a host system 300.

[0028] The color signal sensor 210 is used to detect a first hue fraction of at least one test liquid 10 and digitize the first hue fraction. In some embodiments, the test liquid 10 is a colored liquid such as water, liquid, solvent, oil, or cutting fluid; if the test liquid 10 is colorless, hue detection can be assisted by combining one or more environmental sensors 250 (described later). During detection, the test liquid 10 must not be obscured by any obstruction.

[0029] In some embodiments, the digitized first hue fraction includes four sets of 16-bit color channel values, namely red, green, blue and white color digital information; wherein, the 16-bit value is represented in decimal and is between 0 and 65535, and the value determines the intensity of the color channel.

[0030] The signal processing unit 220 is electrically connected to the color signal sensor 210 to receive the digitized first hue score from the color signal sensor 210. In some embodiments, the signal processing unit 220 may be a microprocessor with a communication interface having at least one of the following functions: RS485 / RS232, Ethernet, Wi-Fi, IO communication, etc., and supporting configuration via an embedded webpage (refer to Figures 4 to 9) or the host system via instructions.

[0031] The learning module / threshold module 230 can be electrically connected to the signal processing unit 220 to perform deep learning analysis on the digitized first hue score and to calculate a second hue score by performing mathematical model calculations on the received digitized first hue score, and then transmit the result back to the signal processing unit 220. In some embodiments, the liquid hue sensing and monitoring system 100 further includes an environmental sensor 250 to detect an environmental intensity value of the liquid 10 to be tested and output it to the signal processing unit 220, and the signal processing unit 220 includes receiving environmental intensity values.

Finally, the digitized first hue score is converted into an information node by the signal processing unit and transmitted to the host system 300 for recording and monitoring via the user-specified transmission method (i.e., signal transmission unit 240). That is, the learning module / threshold module 230 analyzes the digitized first hue score, quickly identifies the second hue score of the liquid 10 to be tested, and determines whether the second hue score of the liquid 10 to be tested is within a safe operating range.

[0032] In some embodiments, the color signal sensor 210 further includes outputting a user-defined detection threshold and simultaneously outputting it to the signal processing unit 220 along with the digitized first hue score, thereby performing a determination of whether the second hue score of the liquid 10 to be tested is within the safe operating range.

[0033] The signal transmission unit 240 can be electrically connected to the signal processing unit 220. The signal processing unit 220 transmits the second hue fraction through the signal transmission unit 240. In some embodiments, the signal transmission unit 240 supports Ethernet, Wi-Fi, RS485 / RS232, and IO, and the information transmission standard is one of MQTT, OPC UA, Modbus RTU / TCP, or IO, which can be specified by the user.

[0034] The host system 300 communicates with the signal processing unit 220 through the signal transmission unit 240 to record the second hue score and monitor the hue sensing module 200. In some embodiments, the host system 300 may include a computer host, a controller, and a mobile device, but is not limited thereto.

A practical example will be used for illustration below.

[0041] Please refer to Figure 11. Users can manually set thresholds (i.e., user-defined detection thresholds) based on different environmental factors (i.e., environmental sensor 250) and observation of the output values ​​of color signal sensor 210. Taking Figure 11 as an example, the output values ​​of color signal sensor 210 are [17240, 4451, 4221, 18447] (i.e., the digitized first hue fraction), while the user-defined threshold (i.e., user-defined detection threshold) is [30000, 30000, 30000, 65535].

[0042] As shown in Figure 12, the input of the threshold module in the learning module / threshold module 230 is the output value of the color signal sensor 210 shown in Figure 11 and the user-defined threshold (i.e., the user-defined detection threshold). After calculation, the color is judged, and the color is compared with the score table to obtain the liquid hue score (i.e., the second hue score).

[0043] As shown in Figure 13, the learning module / threshold module 230 uses a deep learning-like neural network. The input layer has 8 neural nodes, which are the output value of the color signal sensor 210 shown in Figure 11 and the user-defined threshold (i.e., the user-defined detection threshold). The hidden learning layer will perform deep learning calculations, and the output layer will be the second hue fraction of the liquid 10 to be tested.

[0044] As shown in Figure 14, after the learning module / threshold module 230 calculates the second hue fraction of the liquid to be tested 10, it will be displayed in the visual chart. When the fraction reaches the danger index, the system will automatically remind the user so that the user can replace the deteriorated liquid in time.

[0045] The liquid hue sensing and monitoring system 100 and the liquid hue sensing and monitoring method S100 described above have the following advantages.

[0046] 1. It can be detected on any liquid that changes color, and can be assisted by environmental sensors (such as pH, sugar content, temperature and humidity).

[0047] 2. Liquid colorimetric detection can be performed without test strips, reagents, chemical agents, or dilution.

[0048] 3. Supports embedded web page settings and upper-level system design methods for rapid deployment.

[0049] 4. Supports individual detection of up to 4 liquid hues and converts them into information nodes (JSON format).

[0050] In summary, the liquid hue sensing and monitoring system and method of the present invention uses a color signal sensor to detect the hue of the liquid. This method eliminates the need for direct contact with the liquid sample, and the liquid sample does not need to be stored separately; the system can be directly installed in the surrounding area. This simplifies the detection process and reduces time costs. In other words, the liquid hue sensing and monitoring system and method of the present invention supports automatic liquid detection, automatically detecting and judging the liquid hue at fixed times. If the system detects an abnormality in the hue of the liquid to be detected, it can also provide an immediate alert, unlike traditional detection methods that still require periodic reagent or test strip testing, significantly reducing the user's operating costs.
