Problems solved by technology

However, if the machine is required to automatically identify, there is still a difficulty. For the same colorless and neutral liquid, neither the color sensor nor the pH value sensor or other existing sensors can be used for measurement and identification, which allows the machine to automatically identify the solution. bring great inconvenience

Embodiment 1

[0067] like Figure 9 As shown, in this embodiment, the method and device provided by the present invention are used to automatically distinguish purified water, milk, 9° white vinegar, 10% sugar water, 10% light salt water and 30% concentrated salt water.

[0068] The specific identification process is as follows:

[0069] Step 1: Pour the liquid to be identified into the liquid container, and put the pH sensor and electrolysis module into the container;

[0070] Step 2: The control unit reads the signal from the receiving end of the photoelectric interfacing module. If the receiving end of the photoelectric interfacing module does not receive the optical signal, it judges that the liquid is opaque, that is, milk, and ends the identification process; otherwise, it judges the liquid It is light-transmitting type, go to the next step to identify;

[0071] Step 3: The control unit reads the signal of the pH sensor and reads its pH value. If it is an acidic liquid, it is judged...

Abstract

The invention relates to a solution distinguishing device based on an electronic measurement technology. The solution distinguishing device comprises a liquid container, a photoelectric correlation module, a pH value sensor, an electrolysis module and a control display unit which is respectively connected with the photoelectric correlation module, the pH value sensor and the electrolysis module; the photoelectric correlation module comprises a transmitting end and a receiving end; the transmitting end and the receiving end are arranged on two sides of the liquid container; the electrolysis module comprises a copper electrode, a PVC protective cap, and a PVC protective sleeve, a screwed pipe joint and an acrylic circular plate which are connected in sequence; a plurality of small holes areformed in the PVC protective cap, detachable connection is achieved through threads and a threaded pipe; the copper electrode is arranged on the acrylic circular plate in a penetrating mode, one end of the copper electrode is arranged in the PVC protective sleeve and connected with the control display unit through a wire, the other end of the copper electrode is arranged in the PVC protective cap.Compared with the prior art, the device has the advantages of being rapid, efficient, capable of achieving automatic distinguishing and the like.

Description

technical field [0001] The invention relates to the field of solution resolution, in particular to a solution resolution device and method based on electronic measurement technology. Background technique [0002] In industrial and agricultural production, daily life and scientific research, various types of solutions are common and widely used. In use, the type of solution is an important parameter. Commonly used methods for identifying the type of solution are based on color, smell, taste or some chemical methods, which are manually identified, lacking in automation and intelligence. For example, for common liquid solutions, such as purified water, sugar water, light salt water, concentrated salt water, milk and white vinegar, etc., most people will distinguish them according to their color, smell and taste, or through some chemical methods. [0003] However, manually using some chemical methods to identify the solution type is inefficient, takes a long time to detect, an...
