Description

Technical Field

[0001] This application relates to the field of hazardous waste transportation, and in particular, to a monitoring method, system, terminal, and storage medium for transporting liquid hazardous waste. Background Art

[0002] Hazardous waste is a type of waste that requires centralized management and strict implementation of destruction or treatment in accordance with standards. Generally, it has one or several dangerous characteristics such as corrosiveness, toxicity, flammability, reactivity, or infectivity.

[0003] During the process of transporting liquid hazardous waste in a factory building, it is usually transported to a specific location through pipeline transportation for centralized treatment. In an environment with high humidity, when the temperature of the hazardous waste is low, condensation water usually forms on the outer surface of the pipeline. However, if there is a small leakage on the outer surface of the pipeline, it is difficult to visually determine whether it is the liquid hazardous waste that has leaked or due to the condensation water on the outer surface of the pipeline, resulting in difficulty in monitoring whether the hazardous waste has leaked. Summary of the Invention

[0004] In order to enable the monitoring of liquid hazardous waste during transportation, this application provides a monitoring method, system, terminal, and storage medium for transporting liquid hazardous waste.

[0005] In a first aspect, a monitoring method for transporting liquid hazardous waste provided by this application adopts the following technical solution:

[0006] A monitoring method for transporting liquid hazardous waste includes:

[0007] Judging whether there is a tendency to form condensation water outside the pipeline;

[0008] If there is a tendency to form condensation water outside the pipeline, after a predetermined interval of time, collect the liquid outside the pipeline;

[0009] Analyze the composition of the liquid to determine whether there is hazardous waste liquid transported inside the pipeline in the liquid;

[0010] If so, determine the location information of the leakage point outside the pipeline and send the leakage point location information to the central control center.

[0011] By adopting the above technical solution, when there is no condensation water on the outer surface of the pipeline, it is possible to quickly judge whether there is a leakage by directly observing whether there is liquid seepage or dripping outside the pipeline. When condensation water is generated outside the pipeline and accumulates to a certain amount, by collecting the liquid on the outer surface of the pipeline and then analyzing the composition of the liquid, it is possible to obtain whether the pipeline has leaked. If the pipeline leaks, the collected liquid will have the composition of hazardous waste or cause other characteristics of the liquid to change.

[0012] Preferably, the method for determining whether there is a tendency to form condensate outside the pipeline includes:

[0013] Obtain the current ambient humidity information and the current ambient temperature information;

[0014] Obtain the current pipe wall temperature information;

[0015] Calculate the current dew point temperature information according to the current ambient humidity information and the current ambient temperature information;

[0016] Determine whether the dew point temperature information is greater than the pipe wall temperature information;

[0017] If the dew point temperature information is greater than the pipe wall temperature information, it is determined that there is a tendency to form condensate outside the pipeline.

[0018] By adopting the above technical solution, the phenomenon of condensate condensing and forming outside the pipeline will only occur when the pipe wall temperature is lower than the dew point temperature. Therefore, screening in this way can reduce the number of irrelevant executions and reduce energy consumption.

[0019] Preferably, the method for setting the predetermined interval time includes:

[0020] Input the dew point temperature information and the pipe wall temperature information into a preset query database to call the predetermined interval time to be set;

[0021] Wherein, in the query database, each dew point temperature information and pipe wall temperature information has a corresponding predetermined interval time.

[0022] Preferably, the method for collecting the liquid outside the pipeline includes:

[0023] Send a nozzle opening signal to the nozzle unit. The nozzle unit includes several nozzles facing the pipeline. The nozzles are located directly above the pipeline and are arranged in an array along the extension direction of the pipeline;

[0024] Send a first start signal to the first horizontal movement unit. The first horizontal movement unit has a water-absorbing sponge abutted against the lower part of the pipeline. The first horizontal movement unit drives the water-absorbing sponge to move along the extension direction of the pipeline;

[0025] Determine whether the first horizontal movement unit reaches the collection position;

[0026] If the first horizontal movement unit reaches the collection position, send a squeezing signal to the squeezing unit to squeeze the liquid in the water-absorbing sponge into the collection device.

[0027] By adopting the above technical solution, when the nozzle above blows air, the liquid condensed above the pipeline will flow downward under the action of the gas. At this time, the water-absorbing sponge arranged below the pipeline can better collect the liquid on the pipeline comprehensively, so as to make the analysis of the result more accurate.

[0028] Preferably, a plurality of corresponding light emitters and light receivers are arranged at intervals along the extension direction of the pipeline on the pipeline and directly below the pipeline. The light receivers are used to receive the light emitted by the light emitters, and the connection line between the light receivers and the light emitters is the same as the extension direction of the pipeline;

[0029] The method for determining the external leakage point information of the pipeline includes:

[0030] Send a light emission signal downward to each light emitter;

[0031] When a light receiver does not receive the light emitted by the light emitter, the light receiver uploads light missing information, and the light missing information includes coding information representing the light receiver number;

[0032] Receive the light missing information and determine the pipeline number information according to the coding information. The leakage point position information is located on the pipeline segment corresponding to the pipeline number information;

[0033] Wherein, each light emitter and light receiver corresponds to a pipeline number information.

[0034] By adopting the above technical solution, after blowing air and absorbing the moisture on the outer surface of the pipeline by the water-absorbing sponge, there will no longer be much moisture remaining on the outer surface of the pipeline. At this time, if there is a leaking part on the outer surface of the pipeline, the generation speed of the water droplets will be much greater than the condensation speed of the condensed water, and water droplets will be generated below the pipeline due to the action of gravity. The generated water droplets will be between the light emitter and the light receiver, and the light will be deflected under the action of the water droplets, so that the light receiver cannot receive the corresponding light signal. While the light receivers in the part without water droplets can still obtain the corresponding light signal. Therefore, this method can quickly know which section of the pipeline has a leakage problem.

[0035] Preferably, a second horizontal movement unit is arranged on one side of the pipeline. The second horizontal movement unit is used to control the camera to move along the extension direction of the pipeline. The camera is located on one side of the pipeline in the horizontal direction, and the camera is used to capture image information including the pipeline;

[0036] The method for determining the external leakage point information of the pipeline includes:

[0037] Send a second start signal to the second horizontal movement unit;

[0038] Send a capture signal to the camera to obtain image information containing the pipeline frame by frame;

[0039] Define a preset detection area for the image information;

[0040] Determine the part of the pipeline in the detection area and determine the boundary image of the bottom of the pipeline in the image information;

[0041] Obtain the first color patch average information of several pixel points below the boundary image in the image information according to the boundary image;

[0042] Obtain the second color patch average information of all pixel points below the boundary image in the detection area according to the boundary image;

[0043] Calculate the color difference information between the first color patch average information and the second color patch average information;

[0044] When the color difference information is greater than the preset difference information, send a stop signal to the second horizontal movement unit, and define the position where the camera is facing the pipeline at this time as the leakage point position.

[0045] By adopting the above technical solution, similarly, when water droplets hanging on the bottom of the pipeline are generated, due to the refraction of light, the information of the color patches in this part will change greatly, so the position of the leakage can be better and intuitively defined by means of image recognition.

[0046] Preferably, the method for obtaining the first color patch average information of several pixel points below the boundary image in the image information according to the boundary image includes:

[0047] Obtain the color patch numerical information of each pixel point in a predetermined matrix frame area adjacent to and below the boundary image;

[0048] Average all the color patch numerical information to obtain the first color patch average information;

[0049] Wherein, the upper boundary of the matrix frame area coincides with the boundary image, and the total number of pixel points in the range included in the matrix frame area is always the same.

[0050] In a second aspect, a monitoring system for transporting liquid hazardous waste provided by the present application adopts the following technical solution:

[0051] A monitoring system for transporting liquid hazardous waste, including,

[0052] A condensate judgment module, used to judge whether there is a tendency to form condensate outside the pipeline;

[0053] A condensate collection unit, which is used to collect the liquid outside the pipeline after a predetermined interval of time if there is a tendency to form condensate outside the pipeline;

[0054] A hazardous waste analysis module, which is used to analyze the composition of the liquid to determine whether there is hazardous waste liquid transported inside the pipeline in the liquid;

[0055] A leakage point location information determination module, which is used to determine the leakage point location information outside the pipeline and send the leakage point location information to the central control center if there is any.

[0056] Thirdly, an intelligent terminal provided by the present application adopts the following technical solutions:

[0057] An intelligent terminal includes a memory and a processor, and a computer program capable of being loaded and executed by the processor for the above-mentioned monitoring method of transporting liquid hazardous waste is stored on the memory.

[0058] Fourthly, a computer storage medium provided by the present application, which can store corresponding programs, adopts the following technical solutions:

[0059] A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor for any of the above-mentioned monitoring methods of transporting liquid hazardous waste.

[0060] In summary, the present application includes at least one of the following beneficial technical effects:

[0061] 1. It can better distinguish whether the condensate is formed on the outer wall of the pipeline due to temperature difference and humidity, or the leakage is caused by fine cracks in the pipeline;

[0062] 2. It can quickly judge the leakage location, saving time. Description of the Drawings

[0068] The following further describes the present application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0069] An embodiment of the present application discloses a monitoring method for transporting liquid hazardous waste, which is applied to the pipeline for transporting liquid hazardous waste. It can better distinguish whether the water droplets outside the pipeline are formed due to the leakage of the pipeline or due to the condensation effect. And it can also locate the leakage point relatively quickly, so as to notify the maintenance personnel to respond quickly to repair the leakage point in the first time.

[0070] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after, unless otherwise specified.

[0072] The following further describes the embodiments of the present invention in detail with reference to the drawings of the specification.

[0073] An embodiment of the present invention provides a monitoring method for transporting liquid hazardous waste. The main process of the method is described as follows.

[0074] S100: Determine whether there is a tendency to form condensed water outside the pipeline.

[0075] Among them, for the specific determination method, it includes the steps of:

[0076] S110: Obtain the current ambient humidity information and the current ambient temperature information.

[0077] Among them, the current ambient humidity information refers to the humidity of the environment where the pipeline is located, which can be obtained through a humidity sensor. The current ambient temperature information refers to the temperature of the environment where the pipeline is located, which can be obtained through a temperature sensor.

[0078] S120: Obtain the current pipe wall temperature information.

[0079] Among them, the pipe wall temperature information refers to the temperature of the outer surface of the pipe, which can be obtained by a temperature sensor attached to the outer surface of the pipe.

[0080] S130: Calculate the current dew point temperature information according to the current ambient humidity information and the current ambient temperature information.

[0081] Among them, the dew point temperature information refers to the temperature at which the air cools to saturation under the current ambient humidity information and the current ambient temperature information, which is called the dew point temperature. When the surface of the contacted object is lower than the dew point temperature, the water vapor contained in the air will precipitate on the object surface to form condensed water.

[0082] S140: Determine whether the dew point temperature information is greater than the pipe wall temperature information.

[0083] S150: If the dew point temperature information is greater than the pipe wall temperature information, it is determined that there is a tendency to form condensed water outside the pipe.

[0084] Among them, when the dew point temperature information is greater than the pipe wall temperature information, it means that condensed water will be formed on the pipe wall in the current environment. Therefore, it can be determined that there is a tendency to form condensed water outside the pipe.

[0085] S200: If there is a tendency to form condensed water outside the pipe, after a set interval of time, collect the liquid outside the pipe.

[0086] Among them, the setting of the set interval of time is to leave enough condensed water outside the pipe for collection. Generally speaking, after a set interval of time, the condensed water outside the pipe will form water droplets instead of a misty state, and part of it will gather at the bottom of the outer surface of the pipe under the action of gravity. However, at the same time, other parts of the pipe will still be attached by the misty water mist.

[0087] For the specific setting of the set interval of time, the method can be adopted: input the dew point temperature information and the pipe wall temperature information into a preset query database to call the set interval of time to be set.

[0088] Among them, in the query database, each dew point temperature information and pipe wall temperature information has a corresponding set interval of time. By conducting experiments on each dew point temperature information and each pipe wall temperature information and corresponding the corresponding experimental results one by one to form a query database, the corresponding set interval of time can be directly obtained after inputting the corresponding dew point temperature information and pipe wall temperature information in the subsequent process. Different from this method, the measurement of the corresponding set interval of time can also be achieved by constructing a machine learning model with the dew point temperature information, the pipe wall temperature information and the corresponding experimental results.

[0089] For a specific collection method, a water-absorbing sponge can be used to adsorb the pipeline. Specifically, the water-absorbing sponge is driven by a first horizontal moving unit, which is preferably a rodless cylinder. The water-absorbing sponge is adhered to the driving end of the rodless cylinder by pasting, and the top of the water-absorbing sponge is attached to the bottom of the pipeline. Therefore, the first horizontal moving unit extends along the axial direction of the pipeline and is used to drive the water-absorbing sponge to move along the extension direction of the pipeline.

[0090] In addition, for the water mist-like condensed water remaining on the pipeline, the water mist can be collected to form water droplets by jetting air through air nozzles. Among them, the air nozzles are arranged directly above the pipeline and there are multiple air nozzles. The multiple air nozzles together constitute an air nozzle unit. The multiple air nozzles are arranged in a linear array and along the extension direction of the pipeline.

[0091] As a specific control method, it includes:

[0092] S210: Send an air nozzle opening signal to the air nozzle unit.

[0093] Among them, after receiving the air nozzle opening signal, the air nozzle unit correspondingly opens the air nozzles to jet air towards the pipeline.

[0094] S220: Send a first start signal to the first horizontal moving unit.

[0095] Among them, after receiving the first start signal, the first horizontal moving unit controls the water-absorbing sponge to move correspondingly from one end of the pipeline to the other end.

[0096] S230: Determine whether the first horizontal moving unit reaches the collection position.

[0097] Among them, the collection position is the position when reaching the other end of the pipeline. If the first horizontal moving unit reaches the collection position, it means that the water-absorbing sponge has completely passed through the pipeline and wiped the bottom of the pipeline completely. Here, a water receiving tray for collecting excess water can be attached to the bottom of the water-absorbing sponge, so that the excess water will not leak.

[0098] S240: If the first horizontal moving unit reaches the collection position, send a squeezing signal to the squeezing unit to squeeze the liquid in the water-absorbing sponge into the collection device.

[0099] Among them, the squeezing unit can be a squeezing plate driven by a cylinder that can contact the water-absorbing sponge, and the liquid in the water-absorbing sponge is squeezed out by squeezing the water-absorbing sponge. The collection device is a collection hopper that can receive the water squeezed out by the water-absorbing sponge and is arranged at the collection position.

[0100] S300: Analyze the composition of the liquid to determine whether there is hazardous waste liquid transported in the pipeline in the liquid.

[0101] Among them, according to the different types of hazardous waste liquids, the composition of the liquid in the collection device can be analyzed through different sensors and corresponding indicators. Generally speaking, the purity of condensate water is relatively high. After being mixed into hazardous waste liquids, parameters such as its conductivity and pH value will change to a certain extent. Specifically, through experiments, hazardous waste liquids can be mixed with pure water and compared with pure water to determine which parameters will change, and then analyze the specific changes in the parameters to determine whether there are hazardous waste liquids transported in the pipeline in the collected liquid.

[0102] S400: If there is, determine the location information of the leakage point outside the pipeline and send the leakage point location information to the central control center.

[0103] Among them, the leakage point location information refers to the location where leakage occurs on the pipeline. After the leakage point location information is sent to the central control center, the central control center can send the corresponding leakage point location information to the terminal of the maintenance personnel or notify the maintenance personnel to go to the designated location to repair the pipeline in other ways.

[0104] In an implementation manner, a number of corresponding light emitters and light receivers are arranged at intervals along the extension direction of the pipeline directly below the pipeline. When there is no obstruction between the light emitter and the light receiver, the light emitted by the light emitter will be sent to the corresponding light receiver. Correspondingly, the light receiver can emit a signal indicating whether it has received light as feedback. Among them, the optical paths between each light emitter and light receiver are connected end to end in sequence and pass through all paths in the extension direction of the pipeline. Preferably, the path between the light emitter and the light receiver is located at a position 3 mm - 8 mm below the pipeline.

[0105] Therefore, after collecting the liquid outside the pipeline, the outer surface of the pipeline at the leakage point will continue to ooze liquid. Different from the formation of condensate water on other surfaces of the pipeline through condensation, here, under the action of gravity, liquid droplets will quickly converge below the pipeline. The liquid droplets will block the path between the light receiver and the light emitter. Coupled with the irregular shape of the liquid droplets, the light passing through the liquid will be deflected and it is difficult for the light receiver to perceive it.

[0106] As a specific detection method, it includes the following steps:

[0107] S410: Send a light emission signal downward to each light emitter.

[0108] Among them, when the light emitter receives the light emission signal, the light emitter will emit light to the light receiver.

[0109] S411: When a light receiver does not receive the light emitted by the light emitter, the light receiver uploads the light missing information.

[0110] Among them, the light missing information includes coding information characterizing the number of the light receiver. Each light receiver has a predetermined number. After the light missing information containing the corresponding coding information is uploaded, it can be known which light receiver does not receive the light emitted by the corresponding light emitter through subsequent decoding, and it can be known that there is liquid blocking the normal passage of light on the light path.

[0111] S412: Receive the light missing information and determine the pipeline number information according to the coding information, and the leakage point position information is located on the pipeline segment corresponding to the pipeline number information.

[0112] Among them, there is a corresponding pipeline number information between each light emitter and the light receiver. By knowing the coding information to determine which light receiver is blocked from the light emitter, it can be known that there is a leakage problem in the pipeline corresponding to the pipeline number information.

[0113] In one implementation manner, the leakage point of the pipeline can also be checked by means of machine vision recognition. Specifically, a second horizontal moving unit arranged along the extension direction of the pipeline can be set on one side of the pipeline. A camera for realizing machine vision recognition is fixed on the driving end of the second horizontal moving unit, and the camera is used to capture the image information containing the pipeline. Among them, the camera is located on one side of the pipeline in the horizontal direction, and when there are water droplets converging at the bottom of the pipeline, they can be captured by the camera. Preferably, the center line of the camera is tangent to the lowest point of the pipeline.

[0114] As a specific implementation method, it includes the following steps:

[0115] S420: Send a second start signal to the second horizontal moving unit.

[0116] Among them, the second horizontal moving unit can be a linear drive module such as a rodless cylinder. When the second horizontal moving unit receives the second start signal, it will drive the camera to move smoothly along the preset moving speed.

[0117] S421: Send a capture signal to the camera to obtain the image information containing the pipeline frame by frame.

[0118] Among them, the camera can be a camera or a frame-by-frame camera. When the camera receives the capture signal, it will perform the shooting work correspondingly. Among them, the frame-by-frame image information can be to decompose a continuous video information into multiple images frame by frame, or to shoot images at a predetermined shooting interval to obtain multiple frames of image information.

[0119] S422: Define a preset detection area for the image information.

[0120] Among them, it is preferable to delimit the detection area at the area of the central 50% of the acquired image information.

[0121] S423: Determine the part of the pipeline in the detection area and determine the boundary image of the bottom of the pipeline in the image information.

[0122] Among them, the part where the pipeline is located can be realized by distinguishing the color blocks in the image information. Here, a large color difference can be formed between the background color without the pipeline part and the pipeline, so that the RGB parameters of the pipeline part are quite different from those of the background part. By distinguishing the parts where the differences of each RGB parameter are greater than the preset value as the edge of the pipeline and defining them as boundary color blocks, and then determining the position of the edge-cut image according to the positions of each boundary color block. Generally speaking, the boundary image is a straight line that coincides with the outer contour of the pipeline.

[0123] S424: Obtain the first color block average information of several pixel points located below the boundary image in the image information according to the boundary image.

[0124] Among them, the determined pixel points can be determined by a preset method, and the first color block average information represents the average value of the RGB parameters of all the selected pixel points.

[0125] For the specific acquisition method, it may include:

[0126] Obtain the color block numerical information of each pixel point in a predetermined matrix frame area adjacent to and below the boundary image.

[0127] Among them, the matrix frame area is a preset area range, which represents the range of pixel points to be selected, and the color block numerical information of each pixel point is the RGB parameter of the selected pixel point.

[0128] Average all the color block numerical information to obtain the first color block average information.

[0129] Among them, the upper boundary of the matrix frame area coincides with the boundary image, and the total number of pixel points included in the matrix frame area is always the same. By averaging the RGB parameters corresponding to all the pixel points, the required first color block average information can be obtained.

[0130] S425: Obtain the second color block average information of all pixel points in the detection area and located below the boundary image according to the boundary image.

[0131] Among them, similarly, the second color block average information is the average value of the RGB parameters of all pixel points in the detection area but located below the boundary image.

[0132] S426: Calculate the color difference information between the average information of the first color block and the average information of the second color block.

[0133] Among them, the color difference information refers to the data obtained by subtracting the RGB parameters in the average information of the first color block and the average information of the second color block respectively.

[0134] S427: When the color difference information is greater than the preset difference information, send a stop signal to the second horizontal movement unit, and define the position where the camera is facing the pipeline at this time as the leakage point position.

[0135] Among them, when there are water droplets generated at the bottom of the pipeline, due to the influence of the refraction effect of the water droplets, the color of the water droplet part will change greatly. If it exists in the matrix frame area, the average information of the first color block in the matrix frame area will change greatly, while the average information of the second color block will have a smaller overall change due to the restriction of the background color that contains more color-stable parts not affected by the water droplets. If there are no water droplets generated, the values of the average information of the first color block and the average information of the second color block should both be the background color values, and their differences are also very close. Therefore, when the color difference information between the average information of the first color block and the average information of the second color block is greater than the preset difference information, it can indicate that there are water droplets generated here.

[0136] In one implementation manner, the first two implementation manners can also be mixed, that is, first use the light emitter and the light receiver to quickly locate the pipeline with leakage, and then control the second horizontal movement unit to drive the camera to quickly go to the pipeline corresponding to the pipeline number information to further confirm the leakage point.

[0137] Based on the same inventive concept, the embodiment of the present application also discloses a monitoring system for transporting liquid hazardous waste, which includes:

[0138] A condensate judgment module, used to judge whether there is a tendency to form condensate outside the pipeline.

[0139] A condensate collection unit, if there is a tendency to form condensate outside the pipeline, is used to collect the liquid outside the pipeline after a predetermined interval of time.

[0140] A hazardous waste analysis module, used to analyze the composition of the liquid to judge whether there is hazardous waste liquid transported in the pipeline in the liquid.
