Description

Technical Field

[0001] This application relates to the field of concrete construction monitoring technology, and in particular to a temperature monitoring system for large-volume concrete. Background Technology

[0002] The use of large-volume concrete is very common in large-scale construction projects. However, during the pouring and curing process of large-volume concrete, the temperature difference between the inside and outside may cause cracks, thus affecting the safety of the structure.

[0003] Among the related technologies, it is proposed to record the temperature collected by handheld electronic temperature measuring devices or fixedly installed thermocouples through manual inspection in order to monitor the temperature of concrete.

[0004] However, for super-large structures such as dams, due to their enormous size, it is difficult to monitor the temperature of the concrete in real time using the construction methods in related technologies. This makes it difficult for engineers to obtain effective temperature information in a timely manner to guide the construction. Summary of the Invention

[0005] To help improve the real-time performance of temperature monitoring, this application provides a temperature monitoring system for large-volume concrete.

[0006] This application provides a temperature monitoring system for large-volume concrete, employing the following technical solution:

[0007] A temperature monitoring system for large-volume concrete, the system comprising: two or more data acquisition modules, a signal transmitter, a gateway receiver, and a cloud platform;

[0008] The data acquisition module is fixed on the steel reinforcement structure of the concrete to be poured, and the installation positions of different data acquisition modules are different. The data acquisition module includes a temperature sensor for collecting temperature information at the installation position.

[0009] The signal transmitters are connected to the data acquisition module and the gateway receiver respectively, and are used to acquire the data collected by the data acquisition module and send the data collected by the data acquisition module to the gateway receiver. The number of signal transmitters is less than the number of data acquisition modules.

[0010] The gateway receiver is connected to the cloud platform via a wide area network (WAN) and is used to transmit the data sent by the signal transmitter to the cloud platform via the WAN, so that the cloud platform can monitor the data collected by the data acquisition module.

[0011] The data acquisition module includes a first acquisition module and a second acquisition module. The first acquisition module is installed close to the surface of the steel structure and is used to acquire the surface temperature of the large concrete. The second acquisition module is installed close to the center of the steel structure and is used to acquire the internal temperature of the large concrete.

[0012] The steel reinforcement structure has a cooling water pipe installed inside. The first acquisition module is installed between the cooling water pipe and the surface of the steel reinforcement structure, and the second acquisition module is installed on the side of the cooling water pipe away from the surface of the steel reinforcement structure.

[0013] By adopting the above technical solution, the signal transmitter can send the temperature data collected by the data acquisition module to the gateway receiver, and then the gateway receiver will send the received data to the cloud platform through the wide area network. In this way, the cloud platform can automatically obtain the temperature information collected by the temperature sensor in real time without relying on manual inspection, which can help to realize real-time temperature monitoring and thus accurately guide the construction personnel.

[0014] Optionally, the data acquisition module further includes a humidity sensor for collecting humidity data at the installation location of the data acquisition module.

[0015] By adopting the above technical solution, the cloud platform can not only obtain the temperature data of the concrete, but also the humidity data of the concrete, which can help to analyze the state of the concrete based on the humidity data, and thus help to achieve comprehensive monitoring of the state of the concrete.

[0016] Optionally, the data acquisition module further includes a tilt sensor for acquiring tilt data of the data acquisition module.

[0017] By adopting the above technical solution, the cloud platform can determine whether the position of the data acquisition module has changed by the change of tilt angle data, and thus determine the validity of the data collected by the data acquisition module, which can help improve the accuracy of temperature monitoring.

[0018] Optionally, the gateway receiver further includes a control unit, which is used to detect the data collected by the data acquisition module and, if the data collected by the data acquisition module changes, send the data collected by the data acquisition module to the cloud platform via a wide area network.

[0019] By adopting the above technical solution, the control unit can send the data collected by the data acquisition module to the cloud platform when the data collected by the data acquisition module changes. This can help reduce the amount of data sent to the cloud platform, thereby helping to reduce the data transmission cost of the temperature monitoring system.

[0020] Optionally, the gateway receiver further includes a satellite positioning component for collecting location information corresponding to the gateway receiver;

[0021] The gateway receiver is also used to send the location information to the cloud platform via the wide area network.

[0022] By adopting the above technical solution, the cloud platform can monitor the location of the gateway receiver based on the received location information, which can help avoid problems such as data fraud, and further help verify the authenticity of the received data, thereby improving the effectiveness of monitoring.

[0023] Optionally, the signal transmitter includes two or more data interfaces, and the data acquisition module is connected to the signal transmitter through the data interfaces and sends the acquired data to the signal transmitter through the data interfaces.

[0024] Optionally, the data acquisition interface includes a first interface and a second interface, wherein the type of the first interface is different from the type of the second interface.

[0025] By adopting the above technical solution, since the data acquisition interface includes first and second interfaces of different types, it is possible to connect different types of data acquisition modules to the signal transmitter, thereby facilitating the deployment of the data acquisition modules.

[0026] Optionally, the data acquisition module includes a first acquisition module and a second acquisition module, wherein the first acquisition module is installed close to the surface of the steel reinforcement structure, and the second acquisition module is installed close to the center of the steel reinforcement structure.

[0027] By adopting the above technical solution, the temperature of the concrete surface can be collected by the first acquisition module, and the temperature inside the concrete can be collected by the second acquisition module. In this way, the cloud platform can monitor the temperature difference between the inner and outer surfaces of the concrete in real time based on the data collected by the first acquisition module and the data collected by the second acquisition module, thereby accurately guiding the construction.

[0028] Optionally, a cooling water pipe is installed inside the steel reinforcement structure, the first acquisition module is installed between the cooling water pipe and the surface of the steel reinforcement structure, and the second acquisition module is installed on the side of the cooling water pipe away from the surface of the steel reinforcement structure.

[0029] By adopting the above technical solution, the first acquisition module and the second acquisition module can respectively acquire the temperature on both sides of the cooling water pipe. In this way, the cloud platform can monitor the temperature on both sides of the cooling water pipe through the data acquired by the first acquisition module and the data acquired by the second acquisition module, which can help improve the accuracy of cooling water on / off control.

[0030] Optionally, the signal transmitter is mounted on the steel reinforcement structure, and the gateway receiver is located outside the steel reinforcement structure;

[0031] The data acquisition module is connected to the signal transmitter via a wired connection, and the signal transmitter is connected to the gateway receiver via a wireless connection.

[0032] By adopting the above technical solution, since the gateway receiver is located outside the steel structure, it will not be covered by the concrete after it is poured. This ensures that the gateway receiver can access the wide area network normally, and thus ensures that the gateway receiver can send the received data to the cloud platform.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The signal transmitter can send the temperature data collected by the data acquisition module to the gateway receiver, and then the gateway receiver will send the received data to the cloud platform through the wide area network. In this way, the cloud platform can automatically obtain the temperature information collected by the temperature sensor in real time without relying on manual inspection, which can help to realize real-time temperature monitoring and thus accurately guide the construction personnel.

[0035] 2. The temperature of the concrete surface is collected by the first acquisition module, and the temperature inside the concrete is collected by the second acquisition module. In this way, the cloud platform can monitor the temperature difference between the inner and outer surfaces of the concrete in real time based on the data collected by the first and second acquisition modules, thereby accurately guiding the construction.

Detailed Implementation

[0042] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0043] This application discloses a temperature monitoring system for large-volume concrete. (Refer to...) Figure 1 The large-volume concrete temperature monitoring system includes: two or more data acquisition modules 110, a signal transmitter 120, a gateway receiver 130, and a cloud platform 140.

[0044] The data acquisition module 110 is fixed to the reinforced concrete structure to be poured, and the installation positions of different data acquisition modules 110 vary. (Reference) Figure 2 The data acquisition module 110 includes a temperature sensor 111 for collecting temperature information at the installation location. This allows for real-time acquisition of the internal temperature of the concrete during the concrete pouring process, thus enabling monitoring of the concrete temperature. In practical implementations, the data acquisition module 110 may also include other sensors for collecting other types of data.

[0045] In one example, reference Figure 2 The data acquisition module 110 also includes a humidity sensor 112 for collecting humidity data at the installation location of the data acquisition module 110. Thus, the cloud platform 140 can acquire not only the temperature data of the concrete but also its humidity data, which helps in analyzing the state of the concrete based on the humidity data, thereby facilitating comprehensive monitoring of the concrete's condition.

[0046] In another example, refer to Figure 2The data acquisition module 110 also includes a tilt sensor 113 for collecting tilt data. In actual implementation, the data acquisition module 110 needs to be installed on the reinforcing steel structure before the steel structure is poured. Therefore, during the pouring process, the data acquisition module 110 may detach from the steel structure, causing displacement and resulting in unsuitable data. Since the tilt angle of the data acquisition module 110 changes during this positional change, the cloud platform 140 can determine whether the position of the data acquisition module 110 has changed by monitoring the tilt data, thereby determining the validity of the data collected by the data acquisition module 110. This helps improve the accuracy of temperature monitoring.

[0047] Signal transmitter 120 is connected to both data acquisition module 110 and gateway receiver 130, and is used to acquire data collected by data acquisition module 110 and send the data collected by data acquisition module 110 to gateway receiver 130. The number of signal transmitters 120 is less than the number of data acquisition modules 110. That is, in actual implementation, multiple data acquisition modules 110 can share one signal transmitter 120, which can help reduce the deployment cost of the system.

[0048] The gateway receiver 130 is connected to the cloud platform 140 via a wide area network (e.g., the Internet) to transmit data sent by the signal transmitter 120 to the cloud platform 140, allowing the cloud platform 140 to monitor the data collected by the data acquisition module 110. In one example, the gateway receiver 130 includes a mobile communication module, such as a 5G / 4G communication model. In this case, the gateway receiver 130 can access the wide area network through the mobile communication module. Correspondingly, the cloud platform 140 can run on a backend server and access the wide area network through the backend server. Thus, the gateway receiver 130 and the cloud platform 140 can communicate via the wide area network.

[0049] In one example, the signal transmitter 120 is installed on the reinforced concrete structure, and the gateway receiver 130 is located outside the reinforced concrete structure. The data acquisition module 110 is connected to the signal transmitter 120 via a wired connection, while the signal transmitter 120 is connected to the gateway receiver 130 via a wireless connection. By reasonably selecting the signal transmission method of the signal transmitter 120, it is possible to facilitate the deployment of the data acquisition module 110 while ensuring that the gateway receiver 130 can receive the signals acquired by 110. Furthermore, since the gateway receiver 130 is located outside the reinforced concrete structure, it will not be covered after the concrete is poured, thus ensuring that the gateway receiver can normally access the wide area network and, consequently, ensure that the gateway receiver 130 can send the received data to the cloud platform 140.

[0050] In one example, reference Figure 3 The gateway receiver 130 also includes a satellite positioning component 131, which is used to collect the location information corresponding to the gateway receiver 130. Correspondingly, the gateway receiver 130 is also used to send the location information to the cloud platform 140 through the wide area network.

[0051] Among them, the satellite positioning component 131 supports BeiDou positioning and / or GPS positioning.

[0052] In actual implementation, the gateway receiver 130 can periodically collect location information through the satellite positioning component 131 and send it to the cloud platform 140 via the wide area network.

[0053] Since the gateway receiver 130 is usually deployed close to the data acquisition module 110, and the gateway receiver 130 is directly connected to the cloud platform 140, the cloud platform 140 can monitor the location of the gateway receiver 130 based on the received location information. This can help avoid problems such as data fraud, and further help verify the authenticity of the received data, thereby improving the effectiveness of monitoring.

[0054] The implementation principle of a large-volume concrete temperature monitoring system according to an embodiment of this application is as follows: The temperature monitoring system includes two or more data acquisition modules 110, a signal transmitter 120, a gateway receiver 130, and a cloud platform 140; the data acquisition modules 110 are fixed on the steel reinforcement structure of the concrete to be poured, and the installation positions of different data acquisition modules 110 are different. Each data acquisition module 110 includes a temperature sensor 111 for collecting temperature information at the installation position; the signal transmitter 120 is connected to both the data acquisition modules 110 and the gateway receiver 130 for acquiring the data collected by the data acquisition modules 110 and sending the data collected by the data acquisition modules 110 to the gateway receiver 130. The number of signal transmitters 120 is less than the number of data acquisition modules; the gateway receiver 130 is connected to the cloud platform 140 via a wide area network for sending the data sent by the signal transmitter 120 to the cloud platform 140 via the wide area network, so that the cloud platform 140 can monitor the data collected by the data acquisition modules. By adopting the above technical solution, the signal transmitter 110 can send the temperature data collected by the data acquisition module 120 to the gateway receiver 130, and then the gateway receiver 130 can send the received data to the cloud platform 140 through the wide area network. In this way, the cloud platform 140 can automatically obtain the temperature information collected by the temperature sensor in real time without relying on manual inspection, which can help to realize real-time temperature monitoring and thus accurately guide the construction personnel to carry out construction.

[0055] In some implementations, reference Figure 4The signal transmitter 120 includes two or more data interfaces 121. The data acquisition module 110 is connected to the signal transmitter 120 through the data interface 121 and sends the acquired data to the signal transmitter 120 through the data interface 121.

[0056] Optionally, the data acquisition module 110 includes a data output line for outputting the acquired data. Accordingly, in actual use, the signal output terminal of the data output line is inserted into the data interface 121 to achieve connection with the data interface 121. The structure of the data output terminal matches the structure of the data interface 121.

[0057] In one example, the data acquisition module 110 also includes sensors other than the temperature sensor 111. In this case, different data sensors can correspond to different data output lines. Correspondingly, during the docking process with the signal transmitter 120, the signal output terminals of different data output lines need to be inserted into different data interfaces 121. Thus, a data acquisition module 110 may need to occupy multiple data interfaces 121, so the number of data interfaces 121 may be greater than the number of data acquisition modules 110.

[0058] Further reference Figure 5 The data interface 121 includes a first interface 1211 and a second interface 1212, the types of which are different. In actual implementation, since the types of signal output terminals of the data output lines of different data acquisition modules 110 may differ, and even when the data acquisition module 110 includes multiple data output lines, the types of signal output terminals of the different data output lines may also differ, the signal transmitter 120 includes different types of data interfaces 121. This facilitates the connection of different types of data acquisition modules 110 to the signal transmitter 120, thereby simplifying the deployment of the data acquisition modules 110.

[0059] In some implementations, reference Figure 4 The data acquisition module 110 includes a first acquisition module 1101 and a second acquisition module 1102. The first acquisition module 1101 is installed close to the surface of the steel structure, and the second acquisition module 1102 is installed close to the center of the steel structure.

[0060] Specifically, the first acquisition module 1101 is used to acquire the surface temperature of the large concrete, and the second acquisition module 1102 is used to acquire the internal temperature of the large concrete. In this way, the cloud platform 140 can monitor the temperature difference between the inner and outer surfaces of the concrete in real time based on the data acquired by the first acquisition module 1101 and the data acquired by the second acquisition module 1102, thereby accurately guiding the construction.

[0061] In practice, cooling water pipes are usually pre-installed inside the reinforced concrete structure. When the concrete temperature is too high, cooling water can be introduced into the pre-installed cooling water pipes to reduce the concrete temperature and ensure that the concrete does not crack.

[0062] Furthermore, the first acquisition module 1101 is installed between the cooling water pipe and the surface of the steel structure, that is, on the side of the cooling water pipe closer to the surface of the steel structure, and the second acquisition module 1102 is installed on the side of the cooling water pipe away from the surface of the steel structure. In this way, the cloud platform 140 can monitor the temperature on both sides of the cooling water pipe through the data acquired by the first acquisition module 1101 and the data acquired by the second acquisition module 1102, which can help improve the accuracy of cooling water on / off control.

[0063] In some implementations, the gateway receiver 130 further includes a control unit. The control unit detects the data collected by the data acquisition module 110 and, if the data collected by the data acquisition module 110 changes, transmits the data collected by the data acquisition module 110 to the cloud platform 140 via a wide area network. Specifically, when the gateway receiver 130 receives data from the data acquisition module 110, it compares the received data with the previously received data. If the received data differs from the previously received data, it indicates that the data collected by the data acquisition module 110 has changed. Only then is the received data transmitted to the cloud platform 140. This helps reduce the amount of data transmitted to the cloud platform, thereby reducing the data transmission cost of the temperature monitoring system.

[0064] The above are only some embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
