TECHNICAL FIELD
[0001] The present application relates to the technical field of concrete detection equipment, in particular to a concrete temperature and humidity real-time monitoring and regulating device. BACKGROUND
[0002] During the storage and mixing of concrete, humidity and temperature are key influencing factors. If the humidity is too low, the concrete is prone to dry cracking and clumping, resulting in reduced flowability during subsequent construction and uneven paving. If the humidity is too high, too many bubbles are prone to form inside the concrete, reducing the structural strength after hardening and causing defects such as honeycomb and pitted surface. If the temperature is too low, it will delay the hydration reaction of the concrete and prolong the setting time, affecting the construction progress. If the temperature is too high, it may cause rapid evaporation of water, also causing dry cracking problems. The current common problem is that it is difficult to accurately control the changes in concrete temperature and humidity in real time, and it is not possible to adjust in a timely manner according to the changes, which can easily lead to unstable concrete quality.
[0003] To address the above-mentioned temperature and humidity problems, the conventional method is to use manual periodic detection, manually measuring the temperature and humidity of the concrete with a hygrometer and a thermometer. Some devices are equipped with simple water replenishment or heating components, such as a water tank next to the storage tank, manual valve opening for water replenishment when the concrete is dry, or a heating wire wrapped around the tank, which is powered on to heat when the temperature is too low, to alleviate the impact of abnormal temperature and humidity on concrete quality.
[0004] However, the conventional method has obvious shortcomings, such as long manual detection intervals, inability to capture dynamic changes in temperature and humidity in real time, and easy missed optimal adjustment opportunities. The simple water replenishment component is mostly direct infusion type, with uneven water distribution, which can easily cause local humidity to be too high or still have dry areas.
[0005] Therefore, in view of the existing deficiencies, a concrete temperature and humidity real-time monitoring and regulating device is proposed. SUMMARY
[0006] The purpose of the present application is to provide a concrete temperature and humidity real-time monitoring and regulating device to solve the problems raised in the background.
[0007] To achieve the above-mentioned purpose, the present application provides the following technical solution: a concrete temperature and humidity real-time monitoring and regulating device, comprising: a storage tank, an external frame is arranged outside the storage tank, a control panel is arranged on one side of the upper end of the outside of the storage tank, a buzzer is arranged inside the control panel, an identification camera is arranged at one end of the control panel, a humidity sensor body and a temperature sensor body are arranged at the upper end inside the storage tank; The lens of the recognition camera faces the central area of the surface of the storage tank. The detection end of the humidity sensor extends into the inside of the storage tank and is close to the concrete surface. The temperature sensor is a thermocouple temperature sensor, and the detection end of the temperature sensor is fixed in the middle of the inner wall of the storage tank. The internal structure of the recognition camera uses an improved YOLO target detection algorithm. After grayscale conversion and noise reduction preprocessing of the image captured by the camera, it identifies circular and elliptical contour targets on the concrete surface. By calculating the contour area, quantity and dynamic change frequency, it determines whether the conditions of standing for a preset time after mixing and the emergence of bubbles are met. The internal structure of the recognition camera is also equipped with a feature based on image texture analysis and grayscale gradient detection to extract pixel distribution features of blurred edge areas in the image. When the area of the blurred region exceeds a preset ratio and the grayscale value rises continuously, it is determined that a large amount of hot air is coming out. In addition, the recognition camera can also calculate the color uniformity and texture consistency of the image and statistically analyze the pixel ratio of different grayscale intervals on the concrete surface. When the pixel distribution variance exceeds a preset mixing degree threshold, it is determined that the concrete mixing degree is not high. A splash guard is provided at the middle of the top of the storage tank. An observation port is provided at the middle of the inner side of the splash guard. An adapter is provided at the middle of the top of the splash guard. A servo motor body is provided at the middle of the inner side of the adapter. A stirring rod is provided at the bottom of the servo motor body. A stirring blade is provided on the outside of the stirring rod. A reaction mechanism is provided on the outside of the top of the storage tank. The reaction mechanism includes a water tank, which is located on one side of the top of the storage tank. An auxiliary mechanism is provided on the inner side of the splash guard ring. The auxiliary mechanism includes a central gear, which is located at the connection between the servo motor body and the stirring rod. The bottom of the inner side of the storage tank is provided with an anti-clogging mechanism, which includes a filter plate. The filter plate is located at the lower end of the outside of the stirring rod, and a matching bearing is provided at the connection between the stirring rod and the filter plate.
[0008] Furthermore, the reaction mechanism also includes a water pump, a water supply pipe, a solenoid valve, a liquid distribution pipe, a calcium hydroxide powder tank, a gas supply pipe, an internal cavity, a spray nozzle, and a gas nozzle. A water supply pipe is provided on one side of the water tank, and a water pump is provided on one side of the water supply pipe. A solenoid valve is provided on the outside of the water supply pipe near the water pump. A calcium hydroxide powder tank is provided on one side of the solenoid valve. A gas supply pipe is provided at one end of the calcium hydroxide powder tank. An internal cavity is provided on one side of the gas supply pipe. A gas nozzle is provided in a ring around the outside of the internal cavity. A one-way valve is provided at the connection between the internal cavity and the gas nozzle. A connecting pipe is provided at the other end of the water pump. A ring pipe is provided at the bottom of the connecting pipe, and a spray nozzle is provided in a ring around the bottom of the ring pipe.
[0009] Furthermore, when the temperature sensor detects that the temperature inside the storage tank is lower than the preset temperature threshold, the control panel controls the water pump to introduce water into the calcium hydroxide powder box at a preset flow rate, and the mass ratio of the water introduced to the calcium hydroxide powder body stored in the calcium hydroxide powder box is 1:3-1:5, to ensure that the water and calcium hydroxide powder react fully to generate sufficient heat.
[0010] Furthermore, the detection algorithm of the camera also includes a concrete dryness recognition algorithm. The dryness recognition algorithm extracts the gray value, texture roughness and reflectivity features of the concrete surface in the image captured by the camera. When the gray value is higher than the preset dryness gray value threshold, the texture roughness exceeds the preset roughness threshold and the reflectivity is lower than the preset reflectivity threshold, it is determined that the concrete is relatively dry. The control panel then controls the water pump to draw water from the water tank at a certain preset flow rate and directly introduce it into the storage tank.
[0011] Furthermore, the auxiliary mechanism also includes a half-tooth plate, a collar, an observation port, a slide groove, a ring shaft, a guide plate, an arc strip, and a piercing rod. A half-tooth plate is provided on one side of the outer side of the central gear, a collar is provided on the outer side of the half-tooth plate, a ring shaft is provided through the bottom of the collar, a slide groove is provided on the outer side of the ring shaft, a guide plate is provided on one side of the bottom of the half-tooth plate, an arc strip is provided at one end of the guide plate, and multiple piercing rods are provided on the outer side of the arc strip.
[0012] Furthermore, the arc strip is positioned at the bottom of the stirring blade, and the arc strip is fixedly connected to the chuck rod.
[0013] Furthermore, the piercing rod is a cylindrical structure, and the guide plate and the arc strip are fixedly connected.
[0014] Furthermore, the sawtooth structure of the half-cut toothed plate meshes with the sawtooth structure outside the central gear, and the collar and the ring shaft form a sliding structure.
[0015] Furthermore, the anti-clogging mechanism also includes a scraper, a base plate, and a connecting rod. A scraper is provided on one side of the top of the filter disc, a base plate is provided on one side of the scraper, and a connecting rod is provided on the top of the base plate.
[0016] Furthermore, the connecting rod and the arc strip are fixedly connected, and the bottom of the scraper and the surface of the filter disc are in contact with each other.
[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a reaction mechanism with components such as a water pump, spray nozzles, and a calcium hydroxide powder tank. When a temperature sensor detects that the temperature inside the storage tank is below a preset threshold, the control panel controls the water pump to proportionally introduce water into the calcium hydroxide powder tank. The hot air generated by the reaction is evenly introduced into the tank through the spray nozzles, rapidly increasing the temperature. A recognition camera, using a dryness recognition algorithm, determines that the concrete is too dry, and the water pump directly draws water and sprays it in a mist through the spray nozzles to replenish moisture, achieving precise temperature and humidity control and ensuring the concrete is in a suitable condition. 2. In this invention, when the servo motor drives the stirring rod to rotate, the central gear meshes with the half-tooth plate, causing it to rotate around the ring shaft. This, in turn, drives the arc strip and the chuck rod to move synchronously via the guide plate. When the recognition camera detects that the concrete mixing degree is not high, the control panel increases the servo motor speed and the chuck rod's rotation frequency. The chuck rod then pokes at the bottom of the tank to break up clumps, which, combined with the stirring blades, improves the uniformity of the concrete mixture, meeting the usage requirements. 3. In this invention, the arc-shaped movement of the scraper drives the scraper to rotate around the top of the filter disc via a connecting rod. The scraper contacts the surface of the filter disc, agitating the concrete material on the disc, preventing clogging of the screen holes, and accelerating material discharge. When the concrete mixture is not highly mixed or is relatively dry, the servo motor speed is increased, which accelerates the scraper movement frequency. The water pump replenishes water to optimize the material moisture content, reduce clumping, ensures continuous and smooth material discharge from the filter disc, and improves the operating efficiency of the device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example
[0021] like Figures 1 to 9 As shown, a real-time monitoring and control device for concrete temperature and humidity includes: a storage tank 5, an external frame 6 is provided on the outside of the storage tank 5, a control panel 1 is provided on one side of the upper part of the storage tank 5, a buzzer is provided inside the control panel 1, a recognition camera 2 is provided at one end of the control panel 1, and a humidity sensor body and a temperature sensor body are provided at the upper part of the inside of the storage tank 5. The lens of the identification camera 2 is directed toward the center area of the surface of the storage tank 5. The detection end of the humidity sensor body extends into the inside of the storage tank 5 and is close to the concrete surface. The temperature sensor body is a thermocouple temperature sensor body, and the detection end of the temperature sensor body is fixed in the middle position of the inner wall of the storage tank 5. The internal structure of the identification camera 2 adopts an improved YOLO target detection algorithm. After grayscale conversion and noise reduction preprocessing of the image captured by the camera, it identifies circular and elliptical contour targets on the concrete surface. By calculating the contour area, quantity and dynamic change frequency, it determines whether the conditions of standing for a preset time after mixing and the emergence of bubbles are met. The internal structure of the recognition camera 2 is also equipped with a feature based on image texture analysis and grayscale gradient detection to extract the pixel distribution features of blurred edge areas in the image. When the area of the blurred region exceeds a preset ratio and the grayscale value rises continuously, it is determined that a large amount of hot air is coming out. In addition, the recognition camera 2 can also calculate the color uniformity and texture consistency of the image and statistically analyze the pixel ratio of different grayscale ranges on the concrete surface. When the pixel distribution variance exceeds a preset mixing degree threshold, it is determined that the concrete mixing degree is not high. A splash guard 4 is provided at the middle of the top of the storage tank 5. An observation port 11 is provided at the middle of the inner side of the splash guard 4. An adapter 15 is provided at the middle of the top of the splash guard 4. A servo motor body 13 is provided at the middle of the inner side of the adapter 15. A stirring rod 22 is provided at the bottom of the servo motor body 13. A stirring blade 28 is provided on the outside of the stirring rod 22. A reaction mechanism is provided on the outside of the top of the storage tank 5. The reaction mechanism includes a water tank 3, which is located on one side of the top of the storage tank 5. An auxiliary mechanism is provided on the inner side of the splash ring 4. The auxiliary mechanism includes a central gear 19, which is located at the connection between the servo motor body 13 and the stirring rod 22. An anti-clogging mechanism is provided at the bottom of the inner side of the storage tank 5. The anti-clogging mechanism includes a filter plate 26, which is located at the lower end of the outside of the stirring rod 22. A matching bearing 21 is provided at the connection between the stirring rod 22 and the filter plate 26. After the control panel 1 is activated, the recognition camera 2 begins to continuously capture images of the inside of the storage tank 5, acquiring one frame every 0.5 seconds. Using multiple algorithms, including an improved YOLO target detection algorithm, image texture analysis and grayscale gradient detection, and color uniformity and texture consistency calculation, the camera analyzes the bubbles, heat, and mixing status of the concrete surface in real time. The analysis results are simultaneously transmitted to the control panel 1 for logical judgment. The splash guard 4 and the observation port 11 provide an unobstructed shooting path for the recognition camera 2, while preventing concrete splashes from contaminating the lens during mixing. The servo motor body 13 is electrically connected to the control panel 1. Its start / stop and speed adjustment are controlled by the control panel 1 based on the detection results of the recognition camera 2 and feedback signals from the temperature and humidity sensors. When a "bubble emerging" or "humidity exceeding the standard" signal is received, the servo motor body 13 increases its output speed by 20%-50%. When a "large amount of hot air emerging" signal is received, the servo motor body 13 immediately cuts off power and stops working. After the servo motor body 13 is started, it drives the stirring rod 22 to rotate through the coupling. The stirring rod 22 drives the stirring blade 28 to rotate at the corresponding speed, thereby agitating the concrete material inside the storage tank 5. The agitation intensity is positively correlated with the output speed of the servo motor body 13. The recognition camera 2 captures images of the inside of the mixing tank at 0.5 seconds / frame. The images are first pre-processed by a 5×5 Gaussian filter to reduce noise. The improved YOLOv5 algorithm is used to extract edge gradient features from 10×10 / 20×20 pixel bubble anchor frames. When the outline roundness is detected to be >0.8, the number of single frames is >5, and the number of frames increases dynamically for 3 consecutive frames, it is determined that "bubbles are emerging". Combining grayscale gradient detection and inter-frame difference method, when the proportion of blurred area is greater than 30% and the average grayscale value of 5 consecutive frames increases by more than 5, it is determined that "a large amount of hot air is coming out", and finally the determination result is transmitted to control panel 1 with a high-level digital signal.

A water pipe 16 is provided on one side of the water tank 3, and a water pump 7 is provided on one side of the water pipe 16. A solenoid valve 17 is provided on the outside of the water pipe 16 near the water pump 7. A calcium hydroxide powder tank 20 is provided on one side of the solenoid valve 17. A gas supply pipe 8 is provided at one end of the calcium hydroxide powder tank 20. An internal bladder 27 is provided on one side of the gas supply pipe 8. A jet nozzle 30 is arranged in a ring around the outside of the internal bladder 27. A one-way valve is provided at the connection between the internal bladder 27 and the jet nozzle 30. A connecting pipe is provided at the other end of the water pump 7. A ring pipe is provided at the bottom of the connecting pipe. A spray nozzle 29 is arranged in a ring around the bottom of the ring pipe. When the temperature sensor detects that the temperature inside the storage tank 5 is lower than the preset temperature threshold, the control panel 1 controls the water pump 7 to introduce water into the calcium hydroxide powder box 20 at a preset flow rate. The ratio of the amount of water introduced to the mass of the calcium hydroxide powder stored in the calcium hydroxide powder box 20 is 1:3-1:5, to ensure that the water and calcium hydroxide powder react fully to generate sufficient heat. The camera's detection algorithm also includes a concrete dryness recognition algorithm. The dryness recognition algorithm extracts the gray value, texture roughness, and reflectivity features of the concrete surface from the images captured by the camera. When the gray value is higher than the preset dryness gray value threshold, the texture roughness exceeds the preset roughness threshold, and the reflectivity is lower than the preset reflectivity threshold, it is determined that the concrete is relatively dry. The control panel 1 then controls the water pump 7 to draw water from the water tank 3 at a certain preset flow rate and directly introduce it into the storage tank 5. When the concrete inside storage tank 5 is relatively dry, the recognition camera 2 extracts the surface grayscale value, texture roughness, and reflectivity features of the concrete using a dryness recognition algorithm. When all three features reach a preset threshold, a "concrete is relatively dry" judgment signal is generated and sent to the control panel 1. Upon receiving the signal, the control panel 1 immediately starts the water pump 7 and simultaneously closes the solenoid valve 17, allowing the water pump 7 to draw water from the water tank 3. The water is then introduced into the spray nozzles 29 through connecting pipes and annular pipes. The spray nozzles 29 are evenly distributed in an annular pattern, spraying the water into the storage tank 5 in a mist form to ensure uniform mixing of the water and concrete. The operating flow rate of the water pump 7 is maintained at 5-10 L / min until the recognition camera 2 detects that the concrete dryness has returned to the normal range, at which point the control panel 1 stops the water pump 7. Furthermore, when the temperature sensor detects that the temperature of the material inside the storage tank 5 is lower than the preset temperature threshold, the control panel 1 simultaneously sends a signal to the water pump 7 and the solenoid valve 17. The water pump 7 starts to draw water from the water tank 3, and the solenoid valve 17 is energized and opened, allowing the water to be precisely introduced into the calcium hydroxide powder box 20 through the water pipe 16 and the liquid distribution pipe 18. The water and calcium hydroxide powder react fully at a mass ratio of 1:3 to 1:5 to generate a large amount of hot gas. The hot gas is introduced into the built-in bladder 27 through the gas supply pipe 8, causing the built-in bladder 27 to inflate. When the gas pressure inside the bladder reaches 0.3 MPa, the one-way valve between the built-in bladder 27 and the air nozzle 30 automatically opens. The air nozzles 30 are distributed in a ring around the outside of the built-in bladder 27, evenly introducing the hot gas into the interior of the storage tank 5, achieving a rapid increase in the temperature inside the tank until the temperature sensor detects that the temperature has reached the preset threshold. At this point, the control panel 1 controls the water pump 7 to stop working and the solenoid valve 17 to close.
[0023] Example 2: Figures 1 to 9 As shown, the auxiliary mechanism also includes a half-tooth plate 9, a collar 10, an observation port 11, a slide groove 12, a ring shaft 14, a guide plate 33, an arc strip 31, and a piercing rod 32. A half-tooth plate 9 is provided on one side of the outer side of the central gear 19. A collar 10 is provided on the outer side of the half-tooth plate 9. A ring shaft 14 is provided through the bottom of the collar 10. A slide groove 12 is provided on the outer side of the ring shaft 14. A guide plate 33 is provided on one side of the bottom of the half-tooth plate 9. An arc strip 31 is provided at one end of the guide plate 33. Multiple piercing rods 32 are provided on the outer side of the arc strip 31. The arc strip 31 is located at the bottom of the stirring blade 28, and the arc strip 31 is fixedly connected to the tug rod 32; The piercing rod 32 is a cylindrical structure, and the guide plate 33 and the arc strip 31 are fixedly connected. The sawtooth structure of the half-cut tooth plate 9 meshes with the sawtooth structure on the outside of the central gear 19, and the collar 10 and the ring shaft 14 form a sliding structure. When the servo motor body 13 drives the stirring rod 22 to rotate, the central gear 19 rotates synchronously with the stirring rod 22. The sawtooth structure of the central gear 19 meshes with the sawtooth structure of the half-cut toothed plate 9, thereby driving the half-cut toothed plate 9 to rotate around the ring shaft 14. The collar 10 is fixedly connected to the half-cut toothed plate 9 and slides along the slide groove 12 outside the ring shaft 14 as the half-cut toothed plate 9 moves. The return spring sleeved outside the ring shaft 14 undergoes elastic deformation when the half-cut toothed plate 9 moves. When the speed of the servo motor body 13 decreases or stops, the elastic force of the return spring drives the collar 10 and the half-cut toothed plate 9 to return to the initial position.
[0024] In addition, when the recognition camera 2 detects that the concrete mixing degree is not high, the control panel 1 controls the servo motor body 13 to increase the speed, and the rotation speed of the central gear 19 increases synchronously, which drives the half tooth plate 9 to increase the frequency of its circumferential motion. The half tooth plate 9 drives the arc strip 31 and the chuck rod 32 to circumferentially move at a higher frequency through the guide plate 33.
[0025] The piercing rod 32 is a cylindrical structure with its lower end close to the bottom of the inner side of the storage tank 5. During the circular motion, it continuously pierces the concrete material accumulated at the lower end of the inner side of the storage tank 5, breaking up the material clumps. Combined with the stirring of the mixing blade 28, it improves the overall uniformity of concrete mixing until the recognition camera 2 detects that the mixing degree has reached the preset threshold. Then, the control panel 1 controls the servo motor body 13 to return to the normal speed.
[0026] Example 3: Figures 1 to 9 As shown, the anti-clogging mechanism also includes a scraper 25, a bottom plate 24, and a connecting rod 23. A scraper 25 is provided on one side of the top of the filter disc 26, a bottom plate 24 is provided on one side of the scraper 25, and a connecting rod 23 is provided on the top of the bottom plate 24. The connecting rod 23 and the arc strip 31 are fixedly connected, and the bottom of the scraper 25 is in contact with the surface of the filter disc 26. When the arc strip 31 is in a circular motion, it drives the bottom plate 24 and scraper 25 to move synchronously around the top of the filter disc 26 via the connecting rod 23. The filter disc 26 is located at the bottom inside the storage tank 5, and its surface has evenly distributed screen holes. The concrete material needs to be discharged through the screen holes. The bottom of the scraper 25 is in close contact with the surface of the filter disc 26, and continuously agitates the concrete material on the surface of the filter disc 26 during the circular motion, preventing the material from accumulating and clogging at the screen holes, while smoothing the surface of the material and accelerating the discharge of the material through the screen holes. When the recognition camera 2 detects that the concrete mixture is not mixed well or is too dry, the control panel 1 controls the servo motor body 13 to increase its speed and the water pump 7 to start water replenishment. The increased speed of the servo motor body 13 drives the arc strip 31 and scraper 25 to move at a faster frequency, improving the anti-clogging efficiency; the water pump 7 replenishes water to bring the concrete moisture to a reasonable range, preventing the filter disc 26 from clogging due to the material being too dry and clumping together. The solenoid valve 17 is electrically connected to the control panel 1. When the water pump 7 switches the water supply path to directly supply water to the storage tank or to the calcium hydroxide powder box, the solenoid valve 17 starts and stops precisely to ensure that the water path switching is correct, avoid water waste or insufficient reaction, and indirectly ensure the normal discharge of materials from the filter plate 26.
