Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a method and system for controlling the temperature of concrete for moisturizing and curing based on electric heating wire. Background Technology

[0002] Post-concrete curing with moisture is crucial for ensuring strength development and preventing cracking. Temperature control is the core element of the curing process; the temperature gradient between the concrete's interior and surface must be controlled within the allowable range specified in the code (usually ≤25℃). Otherwise, internal stress can easily arise due to thermal expansion and contraction, leading to harmful cracks. Existing temperature control schemes for concrete curing with moisture have the following shortcomings:

[0003] Traditional maintenance relies heavily on manual, fixed-point temperature measurement, which only monitors the temperature of the concrete surface and ignores the temperature changes in the internal temperature layer, making it impossible to grasp the overall temperature distribution. In addition, the random sampling interval makes it easy to miss the nodes of temperature change, resulting in delayed control commands and inability to intervene in time to address the problem of excessive temperature difference in the temperature layer.

[0004] Some curing schemes in low-temperature environments use electric heating wires to assist in temperature control, but they only rely on fixed durations (such as heating for 8 hours a day) or surface temperature thresholds (such as starting when the surface temperature is <10℃) for control, without considering the rationality of temperature changes in different layers of concrete. Overheating can lead to abnormal concrete strength development, while insufficient heating cannot solve the problem of excessive internal cooling. Summary of the Invention

[0010] The temperature assessment module is used to associate the temperature of the marked temperature layer, calculate the temperature error rate, and assess the acceptability of temperature changes.

[0011] The electric heating wire control module is used to control the working state of the electric heating wire based on the comparison result between the average temperature change acceptance value and the preset acceptance threshold.

[0027] The threshold comparison unit is used to compare the calculated average acceptance rate with a preset acceptance rate threshold to generate a comparison result.

[0028] The state control unit is used to control the working state of the electric heating wire according to the comparison results: if the average temperature change acceptance is less than or equal to the preset acceptance threshold, the electric heating wire is controlled to start heating, and then switched to a silent state after the temperature reaches the preset heating temperature threshold; if the average acceptance is greater than the preset acceptance threshold, the electric heating wire is controlled to remain in a silent state.

[0029] A method for controlling the temperature of concrete curing based on electric heating wire, the method includes the following steps:

[0030] Step S1: Configure the temperature sampling time instruction according to the humidity conditions of concrete moist curing, set the temperature sampling time node, and control the infrared thermometer to detect the temperature of the concrete at the temperature sampling time node.

[0031] Step S2: Construct a three-dimensional model for concrete temperature measurement, divide the concrete into multiple temperature layers along the direction from the interior to the exterior surface, and sequentially encode the temperature layers;

[0032] Step S3: Based on the temperature layer and temperature sampling time node, the average temperature of each detected temperature layer is associated and labeled to evaluate the temperature error rate and temperature change acceptance of each temperature layer between adjacent temperature sampling time nodes.

[0033] Step S4: Based on the average value of the temperature change tolerance, instruct the working status of the electric heating wire.

[0034] As a preferred embodiment of the present invention, the specific implementation process of step S1 includes:

[0035] The initialization time command for configuring the concrete temperature sampling time node is triggered when the surface humidity of the concrete reaches a preset humidity index after the completion of the moisturizing curing measures.

[0036] During the period between two consecutive initialization time command triggers, a closed-loop time range for moisturizing and maintenance measures is formed. Temperature sampling time nodes are set at equal intervals within this closed-loop time range and uniformly coded. Based on the order of the temperature sampling time nodes within the closed-loop time range, the a-th temperature sampling time node is denoted as... ;

[0037] At the specified temperature sampling time point, the infrared thermometer is instructed to measure the temperature of the concrete.

[0038] As a preferred embodiment of the present invention, the specific implementation process of step S2 includes:

[0039] A three-dimensional model of concrete temperature measurement is constructed. Concrete temperature layers are established from the inside of the concrete to the outside surface of the concrete, and the average temperature in each temperature layer is collected by an infrared thermometer.

[0040] Based on the direction from the inside of the concrete to the outer surface, the temperature layers are sequentially encoded, and the i-th temperature layer is denoted as... .

[0041] As a preferred embodiment of the present invention, the specific implementation process of step S3 includes:

[0042] Based on the encoding rules of the temperature layer and temperature sampling time nodes, the average temperature is marked, and the temperature sampling time nodes are... Time-temperature layer The average temperature is marked as ;

[0043] Based on average temperature Quantitative temperature layer At the temperature sampling time point To the temperature sampling time node Temperature error rate In the formula, Indicates the temperature sampling time node To the temperature sampling time node Duration of time;

[0044] Based on the temperature error rate, the temperature layer of the electric heating wire applied to the concrete is evaluated. Temperature change tolerance In the formula, Indicates the average temperature error rate and , The standard deviation of the temperature error rate and I represents the total number of thermospheres.

[0045] As a preferred embodiment of the present invention, the specific implementation process of step S4 includes:

[0046] Based on the temperature change tolerance, determine whether to activate the electric heating wire:

[0047] Calculate the average value of the tolerance for temperature changes. If the average temperature change acceptance rate is less than or equal to a preset acceptance threshold, the electric heating wire is activated to instruct it to operate at the temperature sampling time point. Heating is performed during operation, and the heating wire is kept silent when the heating temperature threshold is reached. If the average temperature change tolerance is greater than the preset tolerance threshold, the heating wire is instructed to remain silent.

[0048] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0049] The key humidity index for concrete moisturizing curing (surface humidity reaching a preset value, such as 85%) is used as the initial command trigger condition to ensure that the sampling time matches the concrete curing stage. Temperature control is only meaningful when moisturizing measures are effective. Sampling nodes are set at equal intervals (such as once every 30 minutes) within the closed-loop time range (such as 6 hours) to avoid invalid sampling and ensure the continuity of temperature data.

[0050] Considering the temperature gradient from the inside to the surface of concrete, a three-dimensional model (based on BIM technology) is used to divide the temperature layers (e.g., 5-8 layers for large-volume concrete) and encode them sequentially to achieve accurate positioning of the temperature of each temperature layer. Compared with the traditional solution that only monitors the surface temperature, it can comprehensively obtain the temperature status at different depths and grasp the overall temperature distribution.

[0051] By converting temperature changes into quantifiable indicators, the temperature error rate of each temperature layer between adjacent sampling nodes (reflecting the rate of temperature change) is first calculated. Then, the acceptable temperature change (determining whether the change meets the maintenance requirements) is assessed by the mean and standard deviation of the error rate. This assessment method is based on statistical principles, avoiding the subjectivity of human experience. At the same time, a heating temperature threshold is set to ensure that the electric heating wire is heated to a reasonable temperature (such as 22°C) and then shuts down, realizing "heating on demand", which not only ensures the maintenance effect but also reduces energy waste.

[0076] The data storage module is used to store temperature sampling data, stratospheric coding information, temperature error rate, and acceptance assessment results.

[0077] Please see Figure 1In this second embodiment, a method for controlling the temperature of concrete curing based on electric heating wire is provided, applicable to the first embodiment above. In this embodiment, the curing of a large-volume concrete pier cap of a high-speed railway bridge is taken as an example. The pier cap has dimensions of 12m × 9m × 3.5m, a concrete strength grade of C40, and the curing environment is a low-temperature winter environment (outdoor temperature -2 to 8℃), requiring electric heating wire for temperature control. The preset humidity index is set to 85%, the closed-loop time range is set to 6 hours, and the temperature sampling interval is set to 30 minutes (a total of 12 sampling nodes). Five temperature layers are set based on the pier cap thickness. The temperature change acceptance threshold is set to 0.6 to meet the temperature stability requirements of large-volume concrete. The electric heating wire heating temperature threshold is set to 22℃ to meet the suitable temperature range for the strength development of C40 concrete.

[0078] The method includes the following steps:

[0079] Step S1: Configure the temperature sampling time instruction according to the humidity conditions of concrete moist curing, set the temperature sampling time node, and control the infrared thermometer to detect the temperature of the concrete at the temperature sampling time node.

[0080] For example, the initialization time command for the concrete temperature sampling time node is configured. The initialization time command is triggered when the surface humidity of the concrete reaches a preset humidity index after the completion of the moisturizing curing measures.

[0081] During the period between two consecutive initialization time command triggers, a closed-loop time range for moisturizing and maintenance measures is formed. Temperature sampling time nodes are set at equal intervals within this closed-loop time range and uniformly coded. Based on the order of the temperature sampling time nodes within the closed-loop time range, the a-th temperature sampling time node is denoted as... ;

[0082] At the temperature sampling time point, the infrared temperature measuring device is instructed to measure the temperature of the concrete;

[0083] For example, on the first day of maintenance, the humidity sensor detected that the surface humidity of the foundation reached 85% (9:00), and the time command configuration unit automatically generated an initialization command; the sampling node setting unit generated 12 sampling nodes (9:00, 9:30...15:00) within 9:00-15:00 (closed-loop time), coded as T1-T12; the infrared temperature measurement control unit commanded 3 high-precision infrared thermometers (accuracy ±0.3℃) to measure the temperature at each node, and the temperature of each temperature layer at node T1 was as follows: W1=21.2℃, W2=18.5℃, W3=15.8℃, W4=12.3℃, W5=9.1℃.

[0084] Step S2: Construct a three-dimensional model of concrete temperature measurement, divide the concrete into multiple temperature layers along the direction from the inside to the outside surface, and encode the temperature layers sequentially;

[0085] For example, a three-dimensional model of concrete temperature measurement is constructed, and concrete temperature layers are established from the inside of the concrete to the outer surface of the concrete. The average temperature in each temperature layer is collected by an infrared temperature measuring device.

[0086] Based on the direction from the inside of the concrete to the outer surface, the temperature layers are sequentially encoded, and the i-th temperature layer is denoted as... ;

[0087] For example, the three-dimensional model building unit is based on the dimensions of the 12m×9m×3.5m platform and uses BIM technology to build a temperature measurement three-dimensional model. The model mesh accuracy is 0.1m, which can clearly show the spatial location of each temperature layer. The temperature layer division unit divides the temperature layer into 5 temperature layers according to the preset depth range. The 5 temperature layers are coded as W1-W5 in the order of "inside to surface". The code is associated with the temperature data of the T1 node and stored (e.g., "W1-T1: 21.2℃").

[0088] Step S3: Based on the temperature layer and temperature sampling time node, the average temperature of each detected temperature layer is associated and labeled to evaluate the temperature error rate and temperature change acceptance of each temperature layer between adjacent temperature sampling time nodes.

[0089] For example, based on the encoding rules of the temperature layer and temperature sampling time nodes, the average temperature is marked, and the temperature sampling time nodes are... Time-temperature layer The average temperature is marked as ;

[0090] Based on average temperature Quantitative temperature layer At the temperature sampling time point To the temperature sampling time node Temperature error rate In the formula, Indicates the temperature sampling time node To the temperature sampling time node Duration of time;

[0091] Based on the temperature error rate, the temperature layer of the electric heating wire applied to the concrete is evaluated. Temperature change tolerance In the formula, Indicates the average temperature error rate and , The standard deviation of the temperature error rate and I represents the total number of thermospheres;

[0092] For example, taking the interval T5 (11:00) - T6 (11:30) as an example (time interval 0.5 hours), the error rate calculation unit calculates the error rate of each temperature layer: W1: (21.0-21.1) / 0.5=-0.2℃ / h; W2: (18.2-18.3) / 0.5=-0.2℃ / h; W3: (15.5-15.6) / 0.5=-0.2℃ / h; W4: (11.8-12.0) / 0.5=-0.4℃ / h; W5: (8.7-8.9) / 0.5=-0.4℃ / h.

[0093] Step S4: Based on the average value of the temperature change tolerance, instruct the working status of the electric heating wire;

[0094] For example, based on the tolerance to temperature changes, it is determined whether to activate the working state of the electric heating wire:

[0095] Calculate the average value of the tolerance for temperature changes. If the average temperature change acceptance rate is less than or equal to a preset acceptance threshold, the electric heating wire is activated to instruct it to operate at the temperature sampling time point. Heating is performed during operation, and the electric heating wire is kept silent when the heating temperature threshold is reached. If the average temperature change tolerance is greater than the preset tolerance threshold, the electric heating wire is instructed to remain silent.

[0096] For example, on the third day of curing, the average acceptance rate drops to 0.57 (<0.6). At this point, the electric heating wire is started. After the temperature of each temperature layer reaches 22°C, the electric heating wire is switched to a silent state.
