Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present application.

[0022] The core of the present application is to provide a liquid supplement overflow monitoring system of a gas concentration detection sensor, which is used to save chemical reagents and avoid the influence of chemical reagent overflow on the service life of the sensor.

[0023] In order to make the persons skilled in the art better understand the present application, the present application will be further described in detail in the following with reference to the drawings and specific embodiments.

[0024] Figure 1 A structural diagram of a liquid supplement overflow monitoring system of a gas concentration detection sensor provided by the embodiment of the present application is shown in the figure, Figure 2 A structural diagram of another liquid supplement overflow monitoring system of a gas concentration detection sensor provided by the embodiment of the present application is shown in the figure. Figure 1 and Figure 2As shown, the liquid supplement overflow monitoring system comprises: a liquid leakage detection device 1, a controller 2, an alarm device 3 and a collection device 4; the liquid leakage detection device 1 is arranged at a liquid supplement opening 501 formed at the top of the gas concentration detection sensor 5, and is used to detect whether there is reagent overflow at the liquid supplement opening 501; the collection device 4 is arranged around the top edge of the gas concentration detection sensor 5, and is used to collect the overflowed reagent; the controller 2 is connected with the liquid leakage detection device 1 and the alarm device 3 respectively, and is used to control the alarm device 3 to issue an alarm prompt according to the liquid leakage signal fed back by the liquid leakage detection device 1.

[0025] The type and number of the liquid leakage detection device 1 are not specifically limited in the embodiment of the present application, and can include a resistance sensor, a conductivity sensor and a camera, etc. The principle of the resistance sensor for detecting liquid leakage is usually based on the electrical conductivity of the liquid. When liquid leakage occurs, the liquid as a conductor contacts the sensor, causing a change in the resistance value. This change can be detected by a circuit connected to the controller 2, so as to determine the position and degree of the liquid leakage. For example, a common resistance liquid leakage sensor can use a resistor. When liquid leakage occurs, the presence of the liquid reduces the resistance value of the resistor. This changed resistance signal is then converted into an electrical signal for analysis and processing by the controller 2. The resistance sensor can also work by detecting the effect of the liquid on the capacitor. In this case, the sensor contains a capacitor. When the liquid leaks and contacts the capacitor, the capacitance value of the capacitor changes, generating a capacitance signal. This signal can also be detected and analyzed by the controller 2. The conductivity sensor usually consists of two electrodes. The two electrodes are placed in the detection area (at the edge of the liquid supplement opening 501). When no liquid leakage occurs, the medium (such as air) between the electrodes has low conductivity, so there is little or no current flowing between the electrodes. When the liquid leaks onto the sensor, it will connect the two electrodes as a conductor, thereby increasing the current flow and changing the conductivity. The alarm device 3 and the collection device 4 are not specifically limited in the embodiment of the present application. The alarm device 3 can include an indicator light and / or a buzzer. The collection device 4 is used to collect the chemical reagent overflowing from the liquid supplement opening 501, so as to prevent the chemical reagent from corroding the surface of the gas concentration detection sensor 5.

[0026] The liquid leakage detection device 1 of the embodiment of the present application includes a water-contacting color-changing paper and a camera connected with the controller 2, and the camera is used to capture the color-changing state of the water-contacting color-changing paper, and the water-contacting color-changing paper is arranged around the edge of the liquid supplementing opening 501.

[0027] Based on the above embodiment, the liquid leakage detection device 1 of the embodiment of the present application is a resistance sensor or a conductivity sensor, and the detection probe of the resistance sensor or the conductivity sensor is abutted against the edge of the liquid supplementing opening 501.

[0028] As to how to fix the resistance sensor or the conductivity sensor so that the detection probe of the resistance sensor or the conductivity sensor is abutted against the edge of the liquid supplementing opening 501, the embodiment of the present application does not make specific limitation thereon, and the detection probe is abutted against the edge of the liquid supplementing opening 501, which can improve the accuracy of the liquid supplementing overflow detection. Specifically, it can include a fixing support and a clamp connected with the fixing support, and the clamp is used to clamp the resistance sensor or the conductivity sensor, and the clamping fixation of the clamp can facilitate the replacement and adjustment of the position and angle of the detection probe. In addition, the resistance sensor or the conductivity sensor can be connected with the controller 2 through a signal amplification module and an analog-to-digital converter.

[0029] Based on the above embodiment, the liquid leakage detection device 1 of the embodiment of the present application includes a water-contacting color-changing paper and a camera connected with the controller 2, and the camera is used to capture the color-changing state of the water-contacting color-changing paper, and the water-contacting color-changing paper is arranged around the edge of the liquid supplementing opening 501.

[0030] The type of the water-contacting color-changing paper is not specifically limited in the embodiment of the present application, and it can include a water-contacting red test paper or a water-contacting blue test paper, etc. When the water-contacting color-changing paper changes color after contacting water, the camera captures the color change of the water-contacting color-changing paper and feeds back to the controller 2, and the controller 2 can control the alarm device 3 to issue an alarm prompt, and at the same time, it can also control the corresponding liquid supplementing device to pause supplementing liquid to the gas concentration detection sensor 5.

[0031] Based on the above embodiment, the embodiment of the present application further includes a shell, the water-contacting color-changing paper is arranged in the shell, and the bottom edge of the shell is provided with an opening in communication with the edge of the liquid supplementing opening 501.

[0032] The water-sensitive color-changing paper is arranged around the edge of the replenishment port 501, and the corresponding outer casing is also arranged around the edge of the replenishment port 501. The opening is to allow reagent overflowing from the replenishment port 501 to flow smoothly into the water-sensitive color-changing paper. The camera can be placed inside or outside the outer casing. If the camera is placed outside the outer casing, the casing must be made of transparent material. By setting up the outer casing, it is possible to effectively prevent water in the external environment from causing the water-sensitive color-changing paper to change color, thus preventing false judgments of replenishment overflow.

[0033] Based on the above embodiments, the collection device 4 in this application embodiment is an annular water receiving tray, which is arranged around the top edge of the gas concentration detection sensor 5.

[0034] In this embodiment, the annular water receiving tray can be bonded to the top edge of the gas concentration detection sensor 5.
