Description

Technical Field

[0001] The present application relates to the field of liquid detection, and in particular, to a liquid discharge detection method, a liquid discharge detection device, a liquid discharge detection circuit, and a liquid discharge detection system. Background Art

[0002] In various applications where multiple pipes are arranged in parallel for drainage, it is often necessary to detect the presence of water flow in these pipes. For example, detecting the presence of liquid flow in the dispersed filtrate drain pipes of plate and frame filter presses, detecting overflow at the overflow weirs of various reservoir dams, detecting the presence of water flow at the outlet of water pumps, and open-type flow detection in the production of various conductive liquids are all applications. Therefore, an online sensor that can accurately detect the presence of water flow is urgently needed.

[0003] However, currently, flow sensors are installed on pipelines to detect the flow rate of fluid in the pipelines, and then indirectly determine whether there is water flow, or flow velocity sensors are installed on pipelines to indirectly measure whether there is water flow, or pressure sensors are installed on pipelines to detect the pressure in the pipes, and then indirectly determine whether there is water flow, or the infrared return intensity of infrared sensors is used to determine whether there is water flow, and a water collection tank is installed with a drainage hole at the bottom, and a float switch is added to the water collection tank for detection. When the water flow rate is less than the drainage hole, the water level drops and a signal is sent, thereby achieving the purpose of detecting whether there is water flow.

[0027] Example 1

[0028] According to an embodiment of the present invention, an embodiment of a liquid discharge detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] This application provides a method for detecting discharge. Figure 1 FIG. 1 is a flow chart of a method for detecting discharge according to embodiment 1 of the present invention. Figure 1 As shown, the method includes:

[0030] Step S102, obtaining feedback information from a detection device corresponding to the liquid discharge device, wherein the feedback information at least includes a first voltage value of the detection device;

[0031] Step S104: analyzing the feedback information based on the reference information to obtain an analysis result, wherein the reference information includes at least a plurality of reference voltage intervals, the plurality of reference voltage intervals corresponding to a non-leakage state of the drainage device and a plurality of liquid states of the drainage liquid of the drainage device, the liquid state including at least a continuous liquid flow state or an intermittent liquid flow state, and the analysis result is used to indicate the non-leakage state of the drainage device or the liquid state of the target drainage liquid, the target drainage liquid being the drainage liquid flowing through a target drainage path of the drainage device, and the target drainage liquid being used to change the conductivity of the detection device;

[0032] Step S106, when the analysis result is used to indicate the liquid state of the target discharge liquid, converting the analysis result into a voltage signal corresponding to the target discharge liquid, wherein the voltage signal is used to represent the liquid state of the target discharge liquid;

[0033] Step S108: outputting a voltage signal corresponding to the target discharge liquid.

[0034] By adopting the above-mentioned detection method, the reference information is compared and analyzed with the feedback information of the corresponding detection device in the discharge device obtained by actual detection, so as to obtain an analysis result. The analysis result can be used to indicate whether the discharge device is in a non-leaking state or a leaking state. Furthermore, in the state of leakage, the analysis result of the leakage state can also be converted into a voltage signal, and the voltage signal can be output. Since the liquid state of the target discharge liquid represented by the voltage signal includes at least a continuous liquid flow state or an intermittent liquid flow state, the purpose of accurately detecting whether the discharge device has a leakage phenomenon based on the output voltage signal can be achieved.

[0035] Among them, the above-mentioned drainage equipment can include drainage equipment in various single-pipeline application scenarios or drainage equipment in multi-pipeline side-by-side drainage application places. Among them, the equipment applied to the above-mentioned multi-pipeline side-by-side drainage application places include: plate and frame filter press, the detection method is used to detect whether there is liquid flow in the dispersed filtrate drainage pipe of the plate and frame filter press; the overflow weir of various reservoir dams, the detection method is used to detect whether there is overflow at the overflow weir; water pump, the detection method is used to detect whether there is water flow at the water pump outlet; and drainage equipment in various application scenarios such as the production of conductive liquids that requires open detection of fluid flow.

[0036] Exemplarily, the plate and frame filter press mainly detects the moisture content of the discharge material. In this embodiment, when the coal slime enters the plate and frame of the plate and frame filter press and squeezes out water through the filter holes, the multiple nozzles of the plate and frame filter press are detected. If the water flow of the multiple nozzles is in a continuous liquid flow state, the detection device detects a low-level signal; if the coal slime accumulates on the filter plate of the plate and frame filter press, the water permeability of the filter plate decreases, but the liquid flow remains continuous. After a period of feeding, the coal slime accumulates more on the filter plate, which increases the feed pressure and squeezes out the moisture in the coal slime. Then, the squeezed moisture slowly decreases and becomes an intermittent liquid flow state. The detection device detects high and low level alternating signals until the detection device detects a stable high-level signal, indicating that the moisture in the coal slime has been squeezed dry, achieving the product effect, and the feeding can be stopped.

[0037] The detection device can be arranged in the liquid drainage device, so that when the liquid drainage phenomenon exists in the liquid drainage device, the detection device can also be arranged at the target detection position of the liquid drainage device, i.e., the detection device can be located in the liquid drainage path of the liquid drainage device, so that after the liquid in the liquid drainage device flows through the liquid drainage path, the detection device located in the liquid drainage path contacts the liquid in the liquid drainage device, so that the liquid can change the electrical conductivity of the detection device. That is, in the absence of liquid, the detection device can feed back the first information as reference information, and in the case of detecting the presence of liquid in the liquid drainage device, the electrical conductivity of the detection device changes due to the contact of the liquid with the detection device, so that the detection device feeds back the second information, which is different from the reference information, so that whether the liquid exists in the liquid drainage device can be detected.

[0038] The reference information and the feedback information represent the same physical meaning, and the feedback information can be a voltage value, a resistance value, and other parameter values that can change the detection result of the detection device due to the presence of the liquid. Alternatively, a corresponding resistance can be selected according to the conductivity of the liquid to match the resistance value with the corresponding liquid by adjusting the resistance value, so that the detection device can more accurately distinguish whether there is liquid at the target position of the liquid drainage device or whether the state of the liquid is a droplet state or a liquid flow state. For example, the case where the liquid drainage device has no liquid and / or the case where the liquid drainage device is located in the detection liquid can be taken as a reference first, the feedback information of the corresponding detection device when the liquid drainage device has no liquid and / or the feedback information of the corresponding detection device when the liquid drainage device is located in the detection liquid is obtained, and the feedback information is taken as reference information. Then, by comparing and analyzing the reference information and the actually detected feedback information, when the actually detected feedback information cannot correspond to the reference information, it is determined that there is a liquid leakage in the liquid drainage device.

[0039] Furthermore, the reference information includes multiple reference voltage intervals obtained in advance, and the multiple reference voltage intervals may be multiple reference voltage intervals obtained for the detection of only one type of liquid. The reference voltage interval may include a first reference voltage interval, which represents a voltage value interval corresponding to when the detection device is located in a discharge device where no liquid exists after discharge. The reference voltage interval may also include a second reference voltage interval, which represents a voltage value interval corresponding to when the detection device is located in a discharge device where liquid still flows after discharge. The second reference voltage interval includes a first sub-voltage interval and a second sub-voltage interval, wherein the first sub-voltage interval represents a voltage value interval corresponding to when there is an intermittent liquid flow in the discharge device after discharge, and the second sub-voltage interval represents a voltage value interval corresponding to when there is a continuous liquid flow in the discharge device after discharge. The first sub-voltage interval and the second sub-voltage interval do not overlap, and the first reference voltage interval and the second reference voltage interval do not overlap. The above-mentioned first voltage value is the working voltage of the detection device. When the above-mentioned feedback information is the first voltage value, it can be determined whether there is liquid in the discharge device based on whether the first voltage value corresponds to a certain voltage interval in the above-mentioned multiple reference voltage intervals (the first reference voltage interval or the second reference voltage interval).

[0040] The reference voltage interval may also be multiple reference voltage intervals obtained for detecting different types of liquids. For example, the multiple reference voltage intervals may include a voltage value interval corresponding to when the detection device is located in a liquid-discharging device with no liquid present after drainage, a voltage value interval corresponding to when the detection device is located in a first type of liquid, a voltage value interval corresponding to when the detection device is located in a second type of liquid, and a voltage value interval corresponding to when the detection device is located in a third type of liquid. The three different liquids have different electrical conductivities, so that when the detection device is located in the three different liquids, the voltage values ​​detected are different. Therefore, the type of liquid leaking from the liquid-discharging device can be determined based on whether the voltage value actually detected corresponds to one of the three different voltage value intervals.

[0041] When it is determined that there is liquid in the above-mentioned drainage device, in order to more accurately know the leakage situation of the drainage device, the leakage result obtained by the above analysis can be converted into a voltage signal. After the voltage signal is output, the specific liquid state of the leakage can be obtained through the output voltage signal, and the liquid state at least includes a continuous liquid flow state or an intermittent liquid flow state.

[0042] In some optional embodiments, the detection device includes a first conductor and a second conductor that are insulated from each other, with a maximum spacing between the first conductor and the second conductor, the drainage liquid in the target drainage path has a minimum drainage diameter, the maximum spacing is smaller than the minimum drainage diameter, and the first conductor and the second conductor are used to conduct when in contact with the target drainage liquid.

[0043] In the above embodiment, the detection device may be two conductors disposed in the drainage device and spaced apart with a first spacing. The first spacing insulates the first conductor from the second conductor, such that when no liquid is present in the drainage device, the first conductor and the second conductor are disconnected. When liquid is present in the drainage device, the first spacing is uniform when the first and second conductors are parallel, and has a maximum spacing when the first and second conductors are spaced apart but not parallel. Because the minimum diameter of the drainage liquid in the target drainage path of the drainage device is greater than the maximum spacing, the drainage liquid contacts the first and second conductors, causing conduction between the first and second conductors. Furthermore, because the drainage liquid has a certain resistance, the conductivity of the detection device changes, thereby enabling detection of the presence of liquid in the drainage device, thereby accurately detecting leakage from the drainage device. Furthermore, the above-mentioned detection device can be located below the discharge port of the discharge device. Since this position is the target flow path of the discharge liquid, a detection device can be set at this position to more accurately detect whether there is leakage in the discharge device.

[0044] Furthermore, when the drainage device is used for drainage in a multi-pipeline parallel drainage application, the first conductor and the second conductor can be arranged side by side in a direction perpendicular to the multi-pipeline parallel drainage, so that the first conductor and the second conductor are spaced apart.

[0045] In some optional embodiments, converting the analysis result into a voltage signal corresponding to the target discharge liquid includes: converting the analysis result into a level signal when the analysis result indicates that the liquid state of the target discharge liquid is a continuous liquid flow state.

[0046] In the above embodiment, after comparative analysis is performed based on the reference information and feedback information obtained from actual detection, since the analysis result indicates the liquid state of the target drainage liquid, that is, when liquid exists in the above drainage device, in order to further understand the severity of the leakage in the drainage device, the above analysis result can be converted into a voltage signal. Specifically, since the voltage signal when the liquid state of the leakage is a continuous liquid flow state is a continuous and stable voltage signal, that is, when the analysis result when there is no leakage in the drainage device is converted into a voltage signal, if the voltage signal corresponds to a continuous and stable high-level signal, then the voltage signal when there is a continuous liquid flow state in the above drainage device is a continuous and stable low-level signal. Therefore, when the analysis result indicates that the liquid state of the target drainage liquid is a continuous liquid flow state, the purpose of characterizing that the liquid state of the target drainage liquid is a continuous liquid flow state can be achieved by converting the analysis result into a level signal.

[0047] In some optional embodiments, converting the analysis result into a voltage signal corresponding to the target discharge liquid includes: converting the analysis result into a pulse signal when the analysis result indicates that the liquid state of the target discharge liquid is an intermittent liquid flow state.

[0048] In the above embodiment, when the analysis result indicating that there is no leakage in the discharge device is converted into a voltage signal, the voltage signal corresponds to a continuous and stable high-level signal; when there is a continuous liquid flow state in the discharge device, the voltage signal corresponds to a continuous and stable low-level signal; and when the liquid state of the leakage is an intermittent liquid flow state, the voltage signal is represented by alternating changes between a high-level signal and a low-level signal. Therefore, when the analysis result indicates that the liquid state of the target discharge liquid is an intermittent liquid flow state, the analysis result can be converted into a pulse signal to achieve the purpose of characterizing that the liquid state of the target discharge liquid is an intermittent liquid flow state, thereby being able to more accurately detect whether there is leakage in the discharge device.

[0049] In some optional embodiments, outputting a voltage signal corresponding to the target discharge liquid includes: obtaining a first pulse width of the pulse signal; comparing the first pulse width with a reference pulse width, and outputting a pulse signal when the first pulse width is smaller than the reference pulse width, wherein the reference pulse width is the maximum pulse width of the target discharge liquid under an intermittent liquid flow state.

[0050] In the above embodiment, the reference pulse is the duration of time that the detection device is in a high-level state according to a pre-set autonomous setting, that is, the above reference pulse width can be used as the minimum duration between two adjacent leakage phenomena allowing the discharge device to be in an intermittent liquid flow state. That is, when the above first pulse width is smaller than the above reference pulse width, it indicates that the above discharge device is still in an intermittent liquid flow state and outputs the pulse signal, thereby being able to more accurately detect the liquid state of the discharge device leaking.

[0051] In some optional embodiments, the feedback information is analyzed based on the reference information to obtain an analysis result, including: determining whether the first voltage value is within the target voltage range, and outputting a judgment result, wherein the target voltage range is the largest voltage range among multiple reference voltage ranges; if the judgment result indicates yes, outputting a no leakage signal, and the no leakage signal is used to indicate that the discharge device is in a no leakage state; if the judgment result indicates no, outputting a leakage signal, and the leakage signal is used to indicate that the discharge device is in a leakage state.

[0052] In the above embodiment, when the feedback information obtained by the detection device is a first voltage value, the pre-set reference voltage range includes a target voltage range and other voltage ranges, with the target voltage range being the maximum voltage range. When the first voltage value is within the target voltage range, it indicates that the detection device has not detected the presence of liquid at the to-be-detected position of the liquid discharge device, thereby outputting a no-leakage signal. The no-leakage signal is used to indicate that the liquid discharge device is in a no-leakage state. When the first voltage value is not within the target voltage range, a leakage signal is output. The leakage signal is used to indicate that the liquid discharge device is in a leakage state. The leakage signal is further converted into a voltage signal to accurately detect the leakage state of the liquid in the liquid discharge device.

[0053] In some optional embodiments, outputting a voltage signal corresponding to the target discharge liquid includes: outputting indication information corresponding to the voltage signal to a display device, where the indication information is used to indicate a detection result of the discharge device.

[0054] In the above embodiment, the display device is used to obtain the indication information and respond according to the indication information, thereby highlighting the meaning of the voltage signal. For example, the display device can be an LED light, which lights up when there is leaking liquid in the drainage device and turns off when there is no leaking liquid. The display device can also be a buzzer, which sounds when there is leaking liquid in the drainage device and turns off when there is no leaking liquid.

[0055] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0070] like Figure 3 As shown, the above-mentioned discharge detection circuit is composed of the above-mentioned detection unit 302, the analysis unit 304, and the output unit 306. In addition, the discharge detection circuit also includes a 5V power supply and a 24V power supply module. The detection device is electrically connected to the detection unit, and the detection unit 302 is also electrically connected to the 5V power supply and the analysis unit 304 respectively. The analysis unit 304 is also electrically connected to the output unit 306, and the above-mentioned 5V power supply is electrically connected to the above-mentioned analysis unit 304 through the 24V power supply module.

[0071] For example, the main components of the detection unit 302 include an LM393 voltage comparator, such as Figure 3When a 5V power supply is applied to VCC and GND, if there is no liquid discharge in the liquid discharge device, the working state of the detection device detected by the above-mentioned detection unit 302 is a high-impedance state, that is, the positive electrode voltage of the LM393 is higher than the negative electrode voltage (threshold voltage) of the LM393, and DOUT is output. If liquid in the liquid discharge device flows through the detection device, due to the contact between the liquid and the detection device, the detection device is located in the above-mentioned liquid discharge detection circuit, thereby lowering the voltage of the non-inverting input terminal of the LM393 voltage comparator in the detection unit 302. However, when the voltage of the non-inverting input terminal is lower than the voltage of the reverse input terminal, DOUT is disconnected, and the 3.3V signal is amplified to 24V through the above-mentioned 24V power supply module, thereby inputting a signal indicating the presence of liquid to the above-mentioned analysis unit 304. Furthermore, when the discharge state of the above-mentioned discharge device includes a continuous liquid flow state and an intermittent liquid flow state, when the continuous liquid flow state changes to an intermittent liquid flow state, the output unit 306 electrically connected to the analysis unit 304 inputs a pulse signal, and when the pulse width of the input pulse signal is greater than the reference pulse width, a signal indicating that no liquid exists is output.
