[0002] At present, large-volume concrete structures are prone to cracks, so the internal temperature of the concrete must be controlled during the construction process. In engineering practice, the method of burying cooling water pipes is usually adopted to prevent temperature stress cracks in large-volume concrete.

[0034] In this embodiment, the sub-control device is connected to the relay controller 6, and the relay controller 6 controls the operation of the sub-control device.

[0035] In this embodiment, the sub-control device includes a plurality of electromagnetic valves 7, and the plurality of electromagnetic valves 7 are connected to a relay controller 6. The relay controller 6 controls the opening and closing of the electromagnetic valves 7, and further controls the water supply and water stop.

[0036] In this embodiment, a sending end 3 is also included, and the sending end 3 is communicatively connected with the temperature measuring instrument 2 .

[0037] In this embodiment, a user end 4 is also included, and the user end 4 is communicatively connected with the sending end 3 and the bidirectional data adapter 5 respectively.

[0038] This system can optimize and analyze the construction, stress, thermal properties, durability and other requirements of large-volume concrete to ensure that the performance of large-volume concrete meets the high crack resistance required by the design. The temperature control range is calculated by calculating the model test results and combining the specification design. The intelligent and information-based control of water temperature and water flow and the technical means of automatic temperature collection are adopted to effectively control the temperature difference between the inside and outside of the concrete to control the temperature stress cracks of large-volume concrete.

[0039] In this embodiment, the number of the thermal sensors 1 is 24, and each thermal sensor 1 tests the temperature of 24 points of the concrete.

[0040] The temperature of concrete is measured by using a cloud service large-volume concrete thermometer (TG for short). The thermometer 2 has 24 temperature measurement channels. Through the temperature measurement line and data collector, 24 thermistors 1 can be connected at the same time to test the temperature of 24 points of concrete. The working environment of the thermistor 1 is -30~80℃, the measurement range is -30~120℃, and the resolution is 0.1℃. It can be applied to various regional environmental requirements and large-volume concrete temperature monitoring applications. According to the temperature measurement plan, the temperature measurement line is placed at each point. After the thermometer is turned on, it starts to collect data automatically. The temperature collection time interval can be set according to the requirements of the results report, with the shortest interval being 5min and the longest interval being 4h. At the same time, the data is transmitted to the data platform through the SIM card signal. The data platform will display the temperature of each test channel and each test time point. The platform can make a curve graph as required, and the data can be viewed and downloaded at any time.

[0041] The core of control in this system is the bidirectional data adapter 5 (DG for short). The bidirectional data adapter 5 can add sub-control devices, and the sub-control device in this system is a 16-way relay controller. The control logic of the bidirectional data adapter 5 sub-control device can be defined on the workbench. There are 16 channels in total, with symbols J1, J2...J16. The 0 and 1 in front of the # sign are command symbols to control the power-on status. 1 is power-on and water supply, and 0 is power-off and water supply is cut off. The control is based on the relationship between the temperatures of each measuring point in the thermometer 2 as a premise, and is defined according to specific on-site needs. The purpose is to automatically control the power supply status of each channel of the relay controller 6 according to the temperature situation, and then control the opening and closing of the electromagnetic valve 7, so as to achieve automatic control of water supply and water supply.

[0042] In this embodiment, the relay controller 6 is a 16-channel relay controller, the number of the electromagnetic valves 7 is 16, which are respectively connected to the relay controller 6, and the user terminal 4 includes a display screen.

[0043] Thermometer 2 automatically measures temperature and transmits the temperature to the background. Bidirectional data adapter 5 collects all temperature data of a thermometer 2 through logic definition, makes instructions according to the logic definition, and transmits the instructions to relay controller 6 through signal line. Each channel of relay controller 6 is directly connected to the power supply of electromagnetic valve 7. 16 channels can control 16 electromagnetic valves 7. When the channel is powered, the power supply of electromagnetic valve 7 is connected, and electromagnetic valve 7 starts to work. When the channel is powered off, electromagnetic valve 7 stops working. The opening and closing of electromagnetic valve 7 is used to control the inlet and outlet of cold water.

[0044] In this embodiment, the electromagnetic valve 7 is disposed in the cold water pipeline to control the opening and closing of the cold water pipeline.

[0045] Combined with the structural form of the large-volume concrete cross-section and the results of theoretical analysis, 10 groups of cooling water pipes are set in the components, and 3 water storage compartments are set up on site to store water supply, return water, and cooling return water. 1 working container is used for the installation and storage of control equipment and a large screen for real-time display of temperature data. 2 concrete thermometers are used for temperature detection at each temperature measuring point, and 1 bidirectional data adapter 5 is used to receive temperature data and transmit instructions to the relay controller 6 through calculation. 1 relay controller is used to receive instructions and play the power-on and power-off functions.

[0046] In an optional embodiment, nine electromagnetic valves 7 are used to control the delivery and stop of cooling water. The cooling water delivery power adopts three sewage submersible pumps with a power of 1.5KW, which are used to replenish water in the upper, middle and lower cooling water pipes.

[0047] The submersible pump is placed in the water supply compartment and connected to the cooling pipe water inlet through a pipe. An electromagnetic valve 7 is installed in the middle of the pipe. The cooling pipe outlet is connected to the return water compartment through a pipe, the return water compartment is connected to the return water cooling compartment, and the return water cooling compartment is connected to the water supply compartment. Thermometer 2, bidirectional data adapter 5, relay controller 6, and data display screen are placed in the working container. The electromagnetic valve 7 is connected to the relay controller 6 in the container through wires.

[0048] In this embodiment, the sending end 3 sends the temperature data to the cloud.

[0049] Before pouring concrete, complete the purchase and laying of sensors, install monitoring temperature probes at designated embedded locations, and the thermometer 2 automatically measures the temperature and transmits the temperature to the background. The bidirectional data adapter 5 collects all temperature data of a thermometer 2 through logical definition, and defines it in the bidirectional data adapter 5. When the surface temperature measurement point and the center temperature measurement point are > 25°C, make an instruction to the relay controller 6 to open the electromagnetic valve 7 to deliver water. When the temperature is not > 25°C, make an instruction to the relay controller 6 to stop delivering water. If needed, the temperature can also be lowered in advance, and the temperature difference can be adjusted to a difference of 20°C before cooling. The DG equipment collects data from each temperature measurement point every 5 minutes, and will work automatically when the control logic conditions are met, achieving the effect of automatic control.
