[0074] The embodiment of the present application will be further described in detail below in combination with the drawings of the specification. As shown in the drawings, the main flow of the method is described as follows (steps S101-S106): Figure 1

[0075] Step S101, obtaining the concrete mixing information of at least one concrete target area to be measured;

[0076] Before obtaining the concrete mixing information of the concrete target area to be measured, the target area of the concrete to be measured needs to be divided and the number and position of the temperature collection devices need to be confirmed.

[0077] In one possible implementation, before obtaining the at least one concrete target area to be measured, the method further comprises:

[0078] ​Obtaining the to-be-tested concrete basic information, wherein the to-be-tested concrete basic information comprises to-be-tested concrete panoramic information, to-be-tested concrete curing information, concrete proportioning information, and heat conduction information corresponding to the concrete proportioning information;

[0079] In the embodiment, the panoramic information of the concrete is the shape data of the environment around the to-be-tested concrete and the concrete, and the environment around the to-be-tested concrete comprises data affecting the internal temperature of the concrete, such as sunlight data and wind data; the to-be-tested concrete curing information is the curing mode of different parts and regions of the concrete, such as the curing modes of the heat storage method, the steam heating method, and the electric heating method; the concrete proportioning information is the concrete information used by different parts and regions of the to-be-tested concrete; and the heat conduction information is the heat conductivity coefficient corresponding to different proportioning concretes.

[0080] Dividing the to-be-tested concrete into at least one target region based on the to-be-tested concrete curing information and the concrete proportioning information;

[0081] In the embodiment, the to-be-tested concrete is divided into a plurality of target regions, and the temperature of each target region is monitored. The target regions are divided according to the proportioning of the concrete and the concrete curing information, so that the temperature data can be analyzed conveniently;

[0082] If the proportioning and the curing mode of the to-be-tested concrete are both one kind, the to-be-tested concrete can also be divided based on the to-be-tested concrete panoramic information. The embodiment is not limited in particular, for example, a region subjected to sunlight for more than or equal to 8 hours is taken as a target region, and / or a region subjected to wind for more than or equal to 10 hours is taken as a target region. The environmental factors are analyzed, the factors causing the temperature change of the concrete are processed in a targeted manner, so that the monitoring process is more reasonable.

[0083] Calculating the heat conduction value of the target region based on the to-be-tested concrete panoramic information, the to-be-tested concrete curing information, the concrete proportioning information, and the heat conduction information corresponding to the concrete proportioning information;

[0084] In the embodiment, different weights are given to the concrete panoramic information, the to-be-tested concrete curing information, the concrete proportioning information, and the heat conduction information corresponding to the concrete proportioning information, and then the heat conduction value of the target region of the to-be-tested concrete is calculated according to the weights. By setting the weights, the concretes of different target regions can be compared conveniently, and the comparison result is intuitive.

[0085] Determining the setting number and position of the temperature collection device in the target region based on the heat conduction value.

[0086] In the embodiment, the quantity and position of the temperature acquisition device pre-buried in the target region are determined according to the heat conduction value, the plurality of target regions can be sorted according to the size of the heat conduction value, and then the temperature acquisition device is distributed, wherein the position of each region temperature acquisition device can be set at equal intervals, and the position of the temperature acquisition device can also be set according to the concrete part in the concrete target region to be measured, which is not limited in the embodiment. The quantity and position of the temperature acquisition device are determined according to the target region, the region needing accurate monitoring is distinguished, more temperature acquisition devices are arranged in the region needing accurate monitoring, and the monitoring accuracy is improved.

[0087] A plurality of temperature acquisition devices are pre-buried in each concrete target region to be measured, in the embodiment, the temperature acquisition device is a temperature sensor, the temperature sensor selected is a type DS18B20 temperature sensor, which is suitable for the characteristics of slow concrete temperature change, long period and digitalization requirement.

[0088] The main technical parameters of the DS18B20 temperature sensor are as follows:

[0089] 1. Single-wire interface mode, which can realize bidirectional communication between the microprocessor and the DS18B20;

[0090] 2. Temperature measurement range: -55℃ to +125℃;

[0091] 3. Support multi-point networking function, realize multi-point temperature measurement;

[0092] 4. Working power supply: 3.0~5.5V / DC (can use data line parasitic power supply);

[0093] 5. No need for any peripheral components in use;

[0094] 6. Measurement results are transmitted in 9~12-bit digital quantity mode;

[0095] 7. The temperature sensor is protected by a stainless steel protection tube with a diameter of Φ6;

[0096] 8. Suitable for DN15~25, DN40~DN250 various medium industrial pipelines and narrow space equipment temperature measurement;

[0097] 9. Standard installation thread M10X1, M12X1.5, G1 / 2 optional;

[0098] 10. PVC cable direct wiring or German type ball type junction box wiring, convenient for connection with other electrical equipment.

[0099] Through the above temperature sensor setting mode, the internal temperature of the concrete can be detected in time.

[0100] In step S102, for any coagulation target region, a concrete temperature strength model corresponding to the target region of the to-be-tested concrete is selected based on to-be-tested concrete proportion information, wherein each to-be-tested concrete target region corresponds to a concrete temperature strength model.

[0101] Since a large amount of water reducing agent, artificial sand and gravel, and fly ash and slag and other admixtures are used in the concrete in China, the concrete proportions of different to-be-tested concretes are different according to the requirements of the construction engineering, and the concrete temperature strength model suitable for the target region is selected through different concrete proportions.

[0102] Specifically, as shown in FIG. 1, obtaining the concrete temperature strength model includes the following sub-steps: Figure 2

[0103] In step S1020, a preliminary function model of concrete strength with respect to curing temperature and curing time is established.

[0104] Optionally, the preliminary function model of concrete strength is as follows:

[0106] wherein t is an equivalent age, T is a temperature of the concrete within a time, T0 is a reference temperature, Δt is a hardening time increment, f is a concrete strength, t0 is a curing age of a concrete test block, and f0 and t0 are concrete strength parameters.

[0107] It should be noted that the reference temperature refers to a temperature at which the concrete strength no longer increases with the age, i.e., a temperature at which the hydration reaction in the concrete stops. Since different to-be-tested concrete regions are different, the reference temperature can be set and adjusted according to the construction environment and historical level of the to-be-tested concrete.

[0108] In step S1021, a plurality of curing temperatures, a plurality of curing ages corresponding to the curing temperatures, and a plurality of concrete test block strengths corresponding to the curing temperatures are obtained, wherein the concrete test block strength and the curing age correspond to each other, and the concrete test block proportion is the same as the to-be-tested concrete proportion information of the to-be-tested concrete target region.

[0109] In the present example, the above data is saved in a pre-established experimental database, and the data is called through a direct connection between an electronic device and the experimental database. The concrete test block strength is obtained by conducting a compressive strength test experiment on the concrete test block. For example, the curing temperature is set from the beginning to the end, with a total of 4 temperature levels. Each temperature level is increased by 1d as the base from 0.5d in the curing age until 28d, and the strength of the concrete test block is recorded respectively. In the present embodiment, the number of concrete test blocks used in each group is at least three.

[0110] ​​In step S1022, the concrete strength parameter is determined based on the plurality of curing temperatures, the plurality of curing ages corresponding to the plurality of curing temperatures, and the plurality of concrete block strengths corresponding to the plurality of curing temperatures.

[0111] First, the experimental data is substituted into the preliminary function model of the concrete temperature strength to calculate a plurality of concrete strength parameters corresponding to the curing temperature and the curing age. Then, the concrete strength parameters corresponding to the curing temperature are subjected to regression analysis based on a regression analysis algorithm, the concrete strength parameters are verified and corrected, and the concrete strength parameter is determined.

[0112] In step S1023, the preliminary function model of the concrete temperature strength is corrected based on the concrete strength parameter to determine the concrete temperature strength model.

[0113] The concrete strength parameter is input into the preliminary function model of the concrete temperature strength to obtain the concrete temperature strength model.

[0114] In step S103, the temperature and the detection time collected by the current temperature collection device in the at least one target concrete region are obtained.

[0115] In step S104, for any current temperature collection device, the temperature and the time collected by the temperature collection device are input into the corresponding concrete temperature strength model to obtain the concrete strength to be measured.

[0116] In this embodiment, the electronic device substitutes the temperature and the time obtained from the target region temperature collection device into the concrete temperature strength model to calculate the equivalent age of the current position, so that the value of the concrete block curing age is equal to the value of the equivalent age, and then the concrete block curing age is input into the concrete temperature strength model to obtain the concrete strength.

[0117] In step S105, if the concrete strength does not meet the preset concrete strength standard, it is determined whether the current temperature collection device is abnormal.

[0118] Specifically, when the concrete strength does not meet the preset concrete strength standard, the temperature and the time collected by the temperature collection device within a preset time after the time when the concrete strength does not meet the preset concrete strength standard are obtained.

[0119] The step of inputting the temperature and the time collected by the temperature collection device into the corresponding concrete temperature strength model to obtain the concrete strength to be measured is performed.

[0120] Based on the concrete strength to be measured, the temperature collected by the current temperature collection device within a preset division time is divided into a normal temperature set and an abnormal temperature set.

[0121] The temperature collected by the other temperature collection device in the target area is subtracted from the normal temperature set to obtain a first difference value;

[0122] The temperature collected by the other temperature collection device in the target area is subtracted from the abnormal temperature set to obtain a second difference value;

[0123] If the difference between the first difference value and the second difference value is greater than a preset difference value, the current temperature collection device is abnormal.

[0124] In the embodiment, the preset difference value can be set by experience, or can be obtained by data analysis according to a large amount of experimental data, and is not specifically limited.

[0125] If yes, the first alarm information is output.

[0126] The first alarm information is used to remind the staff that the temperature collection device is abnormal, so that the staff can know the abnormal condition of the monitored temperature in time and remind the staff to improve the measured concrete in time.

[0127] The method selects a concrete temperature strength model according to the measured concrete mixing information of the target area of the measured concrete, uses the strength calculated by the current temperature to confirm whether the temperature monitored at the current position is abnormal, further judges that the temperature collection device is abnormal according to the abnormal temperature, and outputs the first alarm signal, so as to remind the staff that the temperature collection device may be damaged or abnormal due to on-site interference, so that the staff can know the reason for the abnormal concrete temperature in time.

[0128] In a possible implementation, if the temperature collection device is abnormal, as shown in the following formula: Figure 3 The method further includes:

[0129] Step a: calculating a current estimated temperature based on a preset temperature processing rule;

[0130] Specifically, the first temperature is calculated based on the first difference value and the average value of the temperature collected by the other temperature collection device in the target area;

[0131] The temperature collected by the temperature collection device in the adjacent target area is subtracted from the normal temperature set to obtain a third difference value;

[0132] The second temperature is calculated based on the third difference value and the average value of the adjacent target area;

[0133] The first temperature and the second temperature are input into a preset weighted average algorithm for calculation to obtain the estimated temperature.

[0134] In the embodiment, the adjacent target area can be one target area or multiple target areas. The worker can set rules for selecting the adjacent target area in advance, and the specific rules are not limited. The estimated temperature is calculated by weighted average calculation, so that the estimation is more accurate and can be used as a reference for the worker.

[0135] In step b, the estimated strength of the to-be-tested concrete at the embedded position of the current temperature acquisition device is calculated based on the current estimated temperature.

[0136] In the embodiment, the strength at the current position is calculated by inputting the estimated temperature into the concrete temperature strength model, so that the worker can refer to it and understand the situation of the to-be-tested concrete at the current position.

[0137] To realize the fusion and visual display of the to-be-tested concrete and the temperature acquisition device data, refer to Figure 4 As an embodiment of the concrete temperature monitoring method, the method further comprises:

[0138] In step S201, a building model based on BIM is established, wherein the building model comprises at least one target area of to-be-tested concrete.

[0139] The user can establish a building model by an electronic device before construction, divide the target area of to-be-tested concrete on the building model, and mark the positions of the temperature acquisition devices in the target area.

[0140] In step S202, the acquisition temperature, acquisition time, and to-be-tested concrete strength of the temperature acquisition device embedded in each to-be-tested concrete target area are marked on the corresponding positions of the building model.

[0141] The electronic device acquires the acquisition temperature and acquisition time of each position of the to-be-tested concrete target area, displays the acquisition temperature at the current time on the building model, and displays the calculated to-be-tested concrete strength on the building model, so that the worker can check the concrete conditions at each position.

[0142] In step S203, if it is determined that the current temperature acquisition device is abnormal, the first alarm information is marked on the corresponding position of the to-be-tested concrete target area of the embedded current temperature acquisition device of the building model; if it is determined that the current temperature acquisition device is not abnormal, the second alarm information is output and marked on the corresponding position of the to-be-tested concrete target area of the embedded current temperature acquisition device of the building model.

[0143] When the temperature sensor is abnormal or the to-be-tested concrete strength is abnormal, the worker is reminded in time through the alarm information.
