Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated beam curing, and in particular relates to an intelligent curing method, system and storage medium for prefabricated beams. Background Art

[0002] The rapid development of transportation and bridge infrastructure has placed higher demands on the quality and quantity of precast beams. During the curing process, traditional spray curing methods primarily rely on manual watering or a simple combination of time relays and solenoid valves. This lacks temperature control during the curing kiln. Although some curing kilns utilize temperature and humidity monitoring, manual spraying is often used to address any abnormalities detected. This lack of controllability can easily lead to unstable temperature and humidity environments within the curing kiln, impacting the quality of the precast beams. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention provides an intelligent curing method, system and storage medium for precast beams, so as to solve the problems in the existing technology that the temperature and humidity change rate during the curing process of precast beams is difficult to control, and the temperature and humidity are inconvenient to adjust in time.

[0004] One embodiment of the present invention provides an intelligent curing method for prefabricated beams, comprising:

[0005] Step S1: Hydrate the prefabricated beam and then place it in a curing kiln, while collecting indoor and outdoor temperatures, beam body temperature, and indoor humidity;

[0006] Step S2: Based on the collected indoor and outdoor temperatures and indoor humidity data, warm water mist is sprayed into the curing kiln to control the temperature in the curing kiln to rise uniformly, so that the precast beam is initially shaped;

[0007] Step S3: Maintaining a constant temperature and humidity environment within a certain range in the curing kiln to further shape the prefabricated beam;

[0008] Step S4: collecting indoor and outdoor temperatures and indoor humidity again, controlling the temperature inside the curing kiln, and causing the temperature inside the curing kiln to drop uniformly to reach the outdoor ambient temperature;

[0009] Step S5: After standing for a preset time, the prefabricated beam is taken out.

[0010] In one embodiment, in step S1, when the precast beam is transferred to the curing kiln, the temperature of the precast beam body is between 40°C and 80°C.

[0011] In one embodiment, the setting time in step S2 is calculated by the following formula:

[0012] (T标 -T 室外温度 ) / h≤k 升 ,

[0013] T 标 is the standard temperature value reached in the curing kiln,

[0014] T 室外温度 is the outdoor temperature value,

[0015] k 升 is the uniform rate of temperature change.

[0016] In one embodiment, in step S2, the temperature in the curing kiln is uniformly increased to between 55°C and 65°C. The temperature in the curing kiln is the standard temperature, and the temperature difference between the warm water mist and the prefabricated beam body is between -5°C ± 20°C.

[0017] In one embodiment, in step S3, the constant temperature in the curing kiln is between 55° C. and 65° C., and the ambient humidity is between 85% and 95%.

[0018] In one embodiment, the setting time in step S4 is calculated by the following formula:

[0019] |(T 室外温度 -T 标 ) / h|≤|k 降 |,

[0020] T 标 is the standard temperature value reached in the curing kiln,

[0021] T 室外温度 is the outdoor temperature value,

[0022] k 降 is the uniform rate of temperature change.

[0023] In one embodiment, in steps S3 and S4, k 升 and|k 降 The value range of | is between 8℃ / h and 10℃ / h, which makes the temperature in the curing kiln rise to the preset temperature or drop to the outdoor temperature at a uniform speed.

[0024] Preferably, the temperature uniformly rising time in the curing kiln in step S2 is 2-4 hours;

[0025] The constant temperature time in the curing kiln in step S3 is 6-10 hours;

[0026] The temperature in the curing kiln in step S3 decreases at a uniform rate for 2-4 hours.

[0027] One embodiment of the present invention further provides an intelligent health care system for precast beams, which is used to execute the intelligent health care method for precast beams as described in any of the above embodiments, comprising:

[0028] Temperature and humidity collection module, used to collect indoor and outdoor temperatures, as well as indoor humidity;

[0029] Hot water spray module, used to provide warm water required for curing of precast beams;

[0030] The control unit is used to control the temperature and humidity acquisition module and the hot water spray module.

[0031] In one embodiment, the temperature and humidity acquisition module includes:

[0032] A temperature and humidity sensor is installed in the curing kiln to monitor the temperature and humidity in the curing kiln;

[0033] A thermometer is installed outside the curing kiln and is used to detect the ambient temperature outside the curing kiln.

[0034] In one embodiment, the control unit receives data fed back by the temperature and humidity acquisition module and regulates the temperature and humidity in the curing kiln.

[0035] In one embodiment, the control unit further includes a temperature and humidity control module for controlling the heating and cooling rates.

[0036] One embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the intelligent health-preserving method described in any of the above embodiments are implemented.

[0037] The intelligent health-preserving method or intelligent health-preserving system provided in the above embodiments has the following beneficial effects:

[0038] 1. The control unit monitors the temperature and humidity changes in the curing kiln, and timely adjusts the temperature and humidity in the curing kiln through the hot water spray module to ensure that the temperature and humidity in the curing kiln are stable during the heating, constant temperature and cooling processes. In particular, during the heating and cooling processes, the heating and cooling rates are kept uniform to ensure that the prefabricated beams adapt to the indoor environment in the curing kiln. Compared with the traditional temperature and humidity monitoring method, the manual spraying method is more intelligent and more controllable, which significantly improves the quality of prefabricated beams and reduces the production of defective prefabricated beams.

[0039] 2. During the heating process, the control unit adjusts the water temperature of the water tank in the hot water spray module according to the temperature of the beam body and the outdoor ambient temperature. The temperature is raised by the atomized gas water temperature generated by the atomized spray of water in the hot water spray module. At the same time, the PID algorithm is used to accurately control the heating rate to ensure that the prefabricated beam can better adapt to the temperature in the curing kiln during the temperature rise process, avoiding quality problems of the prefabricated beam caused by excessive temperature rise;

[0040] During the constant temperature process, the control unit adjusts the water temperature in the hot water spray module according to the temperature of the beam body, the temperature and humidity in the curing kiln, and adopts automatic feedback to adjust the hot water spray system. The mist volume of the atomized gas generated by the atomized spray of water in the hot water spray module is automatically adjusted by the PID algorithm to accurately adjust the temperature and humidity values. The control unit monitors the ambient temperature and humidity in the curing kiln in real time to ensure a constant temperature and humidity in the curing kiln, ensuring that the precast beams in the curing kiln are cured in a constant temperature and humidity environment, avoiding changes in temperature and humidity or untimely regulation that affect the quality of the precast beams;

[0041] During the cooling process, the control unit discharges indoor gas multiple times and introduces outdoor air in small amounts multiple times according to the beam temperature and outdoor ambient temperature. At the same time, the hot water spray module sprays water mist to achieve the effect of uniform cooling in the curing kiln. At the same time, the automatic PID algorithm is used to accurately adjust the temperature to ensure that the prefabricated beams can better adapt to the temperature in the curing kiln during the temperature drop process, preventing the prefabricated beams from being damaged due to drastic changes in temperature.

[0054] Please refer to Figure 1-2One embodiment of the present invention provides an intelligent curing method for prefabricated beams, comprising:

[0055] Step S1: Hydrate the prefabricated beam and then place it in the curing kiln 100, while collecting indoor and outdoor temperatures, beam body temperature, and indoor humidity;

[0056] Step S2: Based on the collected indoor and outdoor temperatures and indoor humidity data, warm water mist is sprayed into the curing kiln 100 to control the temperature in the curing kiln 100 to rise uniformly, so that the precast beam is initially formed;

[0057] Step S3: Maintaining a constant temperature and humidity environment within a certain range in the curing kiln 100 to further shape the prefabricated beam;

[0058] Step S4: collecting indoor and outdoor temperatures and indoor humidity again, controlling the temperature inside the curing kiln 100, and causing the temperature inside the curing kiln 100 to drop uniformly to reach the outdoor ambient temperature;

[0059] Step S5: After standing for a preset time, the prefabricated beam is taken out.

[0060] In the intelligent curing method for precast beams provided in the above embodiment, based on the principle of concrete coagulation and hardening, moist heat curing is divided into four stages: static stop (i.e., step S1 performs outdoor pre-curing on the precast beams), heating (i.e., step S2 controls the temperature in the curing kiln 100 to rise uniformly), constant temperature (i.e., step S3 maintains a constant ambient temperature), and cooling (i.e., step S4 controls the temperature in the curing kiln 100 to drop uniformly to the outdoor temperature environment); in step S5, the preset time value range is 1-2 hours.

[0061] Preferably, in step S4, the outdoor ambient temperature is preferably within a range of ±3°C.

[0062] The temperature and humidity collection module 210 monitors the indoor temperature and humidity of the curing kiln 100 and the outdoor ambient temperature of the curing kiln 100 in real time. The control unit 230 monitors the temperature and humidity data fed back by the temperature and humidity collection module 210 in real time and regulates the hot water in the hot water spray module 220 based on the feedback data from the temperature and humidity collection module 210.

[0063] During the heating process, the control unit 230 adjusts the water temperature of the water tank in the hot water spray module 220 according to the temperature of the beam body and the outdoor ambient temperature. The temperature is increased by the temperature of the atomized gas generated by the atomized spraying of water in the hot water spray module 220. At the same time, a PID algorithm is used to accurately control the heating rate to ensure that the precast beam can better adapt to the temperature in the curing kiln 100 during the temperature rise process, thereby avoiding quality problems of the precast beam caused by excessive temperature rise.

[0064] During the constant temperature process, the control unit 230 adjusts the water temperature in the hot water spray module 220 according to the temperature of the beam body, the temperature and humidity in the curing kiln 100, and adopts automatic feedback to adjust the hot water spray system. The mist volume of the atomized gas generated by the atomized spraying of water in the hot water spray module 220 is automatically adjusted by the PID algorithm to accurately adjust the temperature and humidity values. The control unit 230 monitors the ambient temperature and humidity in the curing kiln 100 in real time to ensure a constant temperature and humidity in the curing kiln 100, and ensures that the precast beams in the curing kiln 100 are cured in a constant temperature and humidity environment, thereby avoiding changes in temperature and humidity or untimely regulation that affect the quality of the precast beams.

[0065] During the cooling process, the control unit 230 discharges indoor gas multiple times and introduces outdoor air in small amounts multiple times according to the beam body temperature and the outdoor ambient temperature. At the same time, the hot water spray module 220 sprays water mist at the same time to achieve the effect of uniform cooling in the curing kiln 100. At the same time, an automatic PID algorithm is used to accurately adjust the temperature to ensure that the prefabricated beams can better adapt to the temperature in the curing kiln 100 during the temperature drop process, preventing the prefabricated beam body temperature from changing drastically and causing damage to the beam body.

[0066] In one embodiment, in step S1, when the precast beam is transferred to the curing kiln 100, the temperature of the precast beam body is between 40°C and 80°C.

[0067] In this embodiment, before the precast beam is sent into the curing kiln 100, the concrete can be hydrated to a certain extent to obtain a certain initial structural strength to resist the swelling effect that occurs during the temperature rise period. When entering the curing kiln 100 for curing, the precast beam has not reached the initial structural strength, and the temperature rise can easily cause its structure to be damaged. At the end of curing, residual deformation is formed, which damages the performance of the concrete.

[0068] In one embodiment, the setting time in step S2 is calculated by the following formula:

[0069] (T 标 -T 室外温度 ) / h≤k 升 ,

[0070] T 标 is the standard temperature value reached in the curing kiln 100,

[0071] T 室外温度 is the outdoor temperature value,

[0072] k 升 is the uniform rate of temperature change.

[0073] In this embodiment, the preferred value of the standard temperature reached in the curing kiln 100 is 60°C (ie, T 标is 60℃), the outdoor temperature is 30℃ (i.e. T 室外温度 is 30℃), the heating time is a variable (h is a variable), and (T 标 -T 室外温度 ) / h / 10℃ / h, that is, (60℃-30℃) / h / 10℃ / h. It is concluded that h is greater than or equal to 3 hours. When the pre-curing time is longer or the initial structural strength is higher, the heating speed is faster; otherwise, the temperature needs to be raised slowly.

[0074] According to the difference between the outdoor temperature and the standard temperature value, preferably, the uniform temperature rise time in the S2 curing kiln is 2-4 hours.

[0075] Please refer to Figure 7 In one embodiment, in step S2, the temperature in the curing kiln 100 is uniformly increased to between 55°C and 65°C. The temperature in the curing kiln 100 is the standard temperature, and the temperature difference between the warm water mist and the precast beam body is between -5°C ± 20°C.

[0076] In this embodiment, the maximum value of the uniform temperature increase is set, and the control unit 230 adjusts the water temperature of the water tank in the hot water spray module 220 according to the temperature of the beam body and the outdoor ambient temperature. The temperature is increased by the temperature of the atomized gas generated by the atomized spraying of water in the hot water spray module 220. At the same time, a PID algorithm is used to accurately control the heating rate to ensure that the precast beam can better adapt to the temperature in the curing kiln 100 during the temperature increase process, thereby avoiding quality problems of the precast beam caused by excessive temperature increase.

[0077] Taking the local outdoor ambient temperature as the standard, the temperature is uniformly increased to 55°C to 65°C, and the heating rate is less than or equal to 10°C / h. When the outdoor ambient temperature is lower than 30°C, the heating time is appropriately extended, and the humidity in the curing kiln 100 needs to be stably increased to 95% during the heating process.

[0078] Please refer to Figure 7 In one embodiment, in step S3, the constant temperature in the curing kiln 100 is between 55° C. and 65° C., and the ambient humidity is between 85% and 95%.

[0079] In this embodiment, the constant temperature time can be 6-10 hours, the constant temperature must be between 55°C and 65°C, and the ambient humidity must be stably maintained between 85-95%. The control unit 230 adjusts the water temperature in the hot water spray module 220 according to the temperature of the beam body, the temperature and humidity in the curing kiln 100, and adopts automatic feedback to adjust the hot water spray system. The mist volume of the atomized gas generated by the atomized spraying of water in the hot water spray module 220 is automatically adjusted by the PID algorithm to accurately adjust the temperature and humidity values. The control unit 230 monitors the ambient temperature and humidity in the curing kiln 100 in real time to ensure constant temperature and humidity in the curing kiln 100, and ensures that the prefabricated beams in the curing kiln 100 are cured in a constant temperature and humidity environment, avoiding changes in temperature and humidity or untimely regulation affecting the quality of the prefabricated beams.

[0080] In one embodiment, the setting time in step S4 is calculated by the following formula:

[0081] |(T 室外温度 -T 标 ) / h|≤|k 降 |,

[0082] T 标 is the standard temperature value reached in the curing kiln 100,

[0083] T 室外温度 is the outdoor temperature value,

[0084] k 降 is the uniform rate of temperature change.

[0085] In this embodiment, the preferred value of the standard temperature reached in the curing kiln 100 is 60°C (ie, T 标 is 60℃), and the outdoor temperature is 30℃ (i.e. T 室外温度 is 30℃), the heating time is a variable (i.e. h is a variable), and we can get |(T 室外温度 -T 标 ) / h| / 10℃ / h, that is, |(30℃-60℃) / h| / 10℃ / h, so h is greater than or equal to 3 hours

[0086] According to the difference between the outdoor temperature and the standard temperature value in the curing kiln, preferably, the uniform temperature drop time in the S2 curing kiln is 2-4 hours.

[0087] Please refer to Figure 7 In one embodiment, in steps S3 and S4, the value range of k rise and |k fall| is between 8°C / h and 10°C / h, so that the temperature in the curing kiln 100 rises to a preset temperature or drops to the outdoor temperature at a uniform speed.

[0088] In this embodiment, the control unit 230 discharges indoor air multiple times and introduces outdoor air in small amounts multiple times according to the temperature of the beam body and the outdoor ambient temperature, and the hot water spray module 220 sprays water mist at the same time, so as to achieve the effect of uniform temperature reduction in the curing kiln 100. At the same time, an automatic PID algorithm is used to accurately adjust the temperature to ensure that the precast beams can better adapt to the temperature in the curing kiln 100 during the temperature drop process, thereby preventing the precast beams from being damaged due to drastic changes in their temperature. When the temperature in the curing kiln 100 reaches the outdoor temperature, the precast beams are left to stand for a period of time to observe whether they are damaged and then removed.

[0089] The optimal cooling time is 3 hours, and the cooling rate should be stable and not higher than 10℃ / h. The temperature in the curing kiln 100 should be reduced to the ambient temperature. When the ambient temperature is less than 30℃, the cooling time should be appropriately extended.

[0090] Please refer to Figure 3-4 One embodiment of the present invention further provides an intelligent health care system 200 for precast beams, which is used to execute the intelligent health care method for precast beams as described in any of the above embodiments, including:

[0091] Temperature and humidity collection module 210, used to collect indoor and outdoor temperatures, as well as indoor humidity;

[0092] Hot water spray module 220, used to provide warm water required for curing of precast beams;

[0093] The control unit 230 is used to control the temperature and humidity acquisition module 210 and the hot water spray module 220 .

[0094] In this embodiment, the hot water spray module 220 includes an atomizing nozzle 221 and a hot water tank 222. The atomizing nozzle 221 is installed in the curing kiln 100. The hot water tank 222 is connected to the control unit 230 via a temperature sensor 223. The hot water tank 222 is provided with a solenoid valve 224, which is controlled by the control unit 230. The control unit 230 collects the temperature in the hot water tank 222 and activates the solenoid valve 224 to perform atomized spraying on the curing kiln 100 based on the temperature and humidity in the curing kiln 100.

[0095] The temperature and humidity collection module 210 monitors the indoor temperature and humidity of the curing kiln 100 and the outdoor ambient temperature of the curing kiln 100 in real time. The control unit 230 monitors the temperature and humidity data fed back by the temperature and humidity collection module 210 in real time and regulates the hot water in the hot water spray module 220 based on the feedback data from the temperature and humidity collection module 210.

[0096] During the heating process, the control unit 230 adjusts the water temperature of the water tank in the hot water spray module 220 according to the temperature of the beam body and the outdoor ambient temperature. The temperature is increased by the temperature of the atomized gas generated by the atomized spraying of water in the hot water spray module 220. At the same time, a PID algorithm is used to accurately control the heating rate to ensure that the precast beam can better adapt to the temperature in the curing kiln 100 during the temperature rise process, thereby avoiding quality problems of the precast beam caused by excessive temperature rise.

[0097] During the constant temperature process, the control unit 230 adjusts the water temperature in the hot water spray module 220 according to the temperature of the beam body, the temperature and humidity in the curing kiln 100, and adopts automatic feedback to adjust the hot water spray system. The mist volume of the atomized gas generated by the atomized spraying of water in the hot water spray module 220 is automatically adjusted by the PID algorithm to accurately adjust the temperature and humidity values. The control unit 230 monitors the ambient temperature and humidity in the curing kiln 100 in real time to ensure a constant temperature and humidity in the curing kiln 100, and ensures that the precast beams in the curing kiln 100 are cured in a constant temperature and humidity environment, thereby avoiding changes in temperature and humidity or untimely regulation that affect the quality of the precast beams.

[0098] During the cooling process, the control unit 230 exhausts indoor air multiple times and introduces small amounts of outdoor air multiple times according to the beam body temperature and the outdoor ambient temperature. At the same time, the hot water spray module 220 sprays water mist at the same time to achieve the effect of uniform cooling in the curing kiln 100. At the same time, an automatic PID algorithm is used to accurately adjust the temperature to ensure that the precast beams can better adapt to the temperature in the curing kiln 100 during the temperature drop process, thereby preventing the precast beams from being damaged due to drastic changes in their temperature.

[0099] The temperature and humidity changes in the curing kiln 100 are monitored by the control unit 230, and the temperature and humidity in the curing kiln 100 are timely regulated by the hot water spray module 220 to ensure that the temperature and humidity in the curing kiln 100 are stable during the heating, constant temperature and cooling processes. In particular, during the heating and cooling processes, the heating and cooling rates are kept uniform to ensure the adaptability of the prefabricated beams to the indoor environment in the curing kiln 100. Compared with the traditional temperature and humidity monitoring method, the manual spraying method is more intelligent and more controllable, which significantly improves the quality of the prefabricated beams and reduces the production of defective prefabricated beams.

[0100] Please refer to Figure 5 In one embodiment, the temperature and humidity acquisition module 210 includes:

[0101] A temperature and humidity sensor 211 is installed in the curing kiln 100 to monitor the temperature and humidity in the curing kiln 100;

[0102] The thermometer 212 is installed outside the curing kiln 100 and is used to detect the ambient temperature outside the curing kiln 100.

[0103] In this embodiment, a temperature and humidity sensor 211 is installed inside the curing kiln 100 to monitor the temperature and humidity inside the curing kiln 100 and to feed the temperature and humidity data back to the control unit 230. A thermometer 212 is installed outside the curing kiln 100 to detect the ambient temperature outside the curing kiln 100. The temperature and humidity sensor 211 monitors the environment inside the curing kiln 100 and feeds the data back to the control unit 230, facilitating the control unit 230 to timely regulate the temperature and humidity inside the curing kiln 100 and enhance the controllability of the precast beam curing process. The control unit 230 receives data fed back by the temperature and humidity acquisition module 210 and regulates the temperature and humidity inside the curing kiln 100 based on the data fed back by the temperature and humidity acquisition module 210.

[0104] Please refer to Figure 3 In one embodiment, the control unit 230 further includes a temperature and humidity control module 231 for controlling the heating and cooling rates.

[0105] Preferably, the control unit 230 may also be provided with a touch screen, and the control unit 230 may be manually controlled via the touch screen.

[0106] In this embodiment, the temperature and humidity control module 231 adopts a precise PID control algorithm, and accurately collects the environmental parameters of each node in the space through the temperature and humidity sensor 211. The control unit 230 relies on the temperature and humidity control module 231 to accurately control the hot water spray module 220 to adjust the hot water based on the temperature and humidity data collected by the temperature and humidity sensor 211, and sprays the hot water in the curing kiln 100 in time to ensure that the temperature and humidity in the curing kiln 100 are controllable.
