Description

Technical Field

[0001] The present invention relates to the field of construction safety technology, and in particular to an intelligent monitoring safety early warning system for construction overload of reinforced concrete structures. Background Art

[0002] Overloading and overloading during existing construction processes frequently cause collapses and subsidence of reinforced concrete structures, leading to safety and quality accidents. This causes casualties, significant economic losses, and significant negative social impacts. Furthermore, during construction, these overloading and overloading can easily cause excessive deformation of reinforced concrete components, leading to numerous cracks and structural defects, necessitating costly repairs. With the widespread adoption of prefabricated residential projects, these residential complexes often feature large underground garages. Due to construction requirements, the roofs of these garages inevitably bear significant construction loads from prefabricated components, concrete transport vehicles, and component transport vehicles. This can lead to significant discrepancies between theoretical calculations and actual data, necessitating a robust and easily applicable safety and quality early warning system to ensure structural quality and safe construction. Furthermore, purely theoretical load calculations can lead to significant deviations during construction and fail to provide realistic protection. Therefore, existing load limit management measures fail to provide intelligent, real-time, and proactive safety control and assurance, nor can they effectively integrate monitoring and early warning systems to create a complete monitoring and early warning system.

[0063] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0064] Example 1

[0065] This embodiment provides a reinforced concrete structure construction overburden intelligent monitoring safety early warning system, such as Figure 1 Shown, including:

[0066] An acquisition module is used to acquire sensor data from preset sensors installed on reinforced concrete components;

[0067] A transmission module, used for transmitting the sensing data to a monitoring module;

[0068] a monitoring module, configured to obtain strain information of each reinforced concrete component based on the sensing data, and determine whether the stress value of each reinforced concrete component reaches a stress limit range according to the strain information;

[0069] The alarm module is used to issue an alarm when the stress value of the reinforced concrete component reaches the stress limit range.

[0070] In this example, the preset sensors can be steel bar stress sensors and concrete deformation sensors installed at stress concentration and deformation control locations of concrete components such as beams, slabs, and columns. Specifically, they can be steel bar stress gauges and concrete deformation sheets. The steel bar stress sensors are used to collect and measure the stress of the steel bars inside the structure and can simultaneously measure the temperature of the buried point. The concrete deformation sensors are used to measure the deformation of the concrete.

[0071] In this example, there are two ways for the transmission module to transmit the sensing data to the detection module, namely wired transmission and wireless transmission;

[0072] In this example, the strain information represents the local relative deformation of the reinforced concrete component under the influence of external forces and non-uniform temperature fields;

[0073] In this example, after receiving the early warning, construction site personnel should stop construction after seeing the on-site sound and light alarms. The on-duty manager in the duty room should first stop construction at the alarm system location according to the emergency plan, and take emergency safety measures such as reducing overburden and reinforcing the structure. Mobile and computer administrators should also take various safety management measures according to the emergency plan.

[0074] In this example, the early warning system is divided into versions 1.0 and 2.0. Version 1.0 is suitable for wired transmission, and version 2.0 is suitable for wireless transmission. Each version is provided with a system platform, which is composed of the monitoring module and alarm module in Example 1, the intelligent display module in Example 2, and the storage module in Example 3. The monitoring module is used for real-time data display and monitoring, the alarm module is used for overload alarm, the display module is used for graphic display, and the storage module is used for data backup.

[0075] like Figure 2As shown, 1.0 is suitable for environments where wired lines can be laid inside the construction site. After the collected data is transmitted to the platform system, the platform will analyze the data and transmit the alarm information to the construction site, the duty room, and the project manager's mobile phone. Through the alarm at multiple points including the construction location, the alarm form includes sound and light alarms at the construction site and the duty room, and pop-up alarms on mobile phones and computers, thus attracting the attention of construction personnel, site managers, and project managers, so that timely and effective safety prevention and control measures can be taken according to the pre-established preventive measures.

[0076] like Figure 3 As shown, the 2.0 system is suitable for construction sites that require good wireless signals from telecommunications systems. Data is transmitted to the system platform through telecommunications wireless restrictions, and then the data and alarm information are transmitted to terminal locations such as construction sites, duty rooms, mobile phones, and computers through the platform for alarm.

[0077] The working principle and beneficial effects of the above technical solution: This system has made a good combination of structural monitoring and alarm, so that both monitoring and alarm functions can fully cover the protected structural system and components. First, the acquisition module collects the sensor data of the preset sensor, and then the transmission module transmits the sensor data to the detection module. In the detection module, it analyzes whether the stress value of each reinforced concrete component has reached the limit, and then the alarm module will sound an alarm under specified circumstances. In this way, the risk of cracking and deformation of the concrete structure can be avoided to the greatest extent, and the resulting maintenance costs can be reduced.

[0078] Example 2

[0079] Based on Example 1, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden further includes:

[0080] Intelligent display module, used to obtain construction structure drawings and establish virtual construction structures;

[0081] The strain information in the monitoring module is obtained, and the strain data of each reinforced concrete component is obtained according to the strain information. The strain data is marked in the virtual construction structure, and a construction structure strain model is established and displayed.

[0082] In this example, the construction structural drawings represent a complete set of construction drawings for a building project, which serve as a reference basis for constructing the building;

[0083] In this example, the strain data represents the current stress in a reinforced concrete;

[0084] In this example, the process of marking the strain data in the virtual construction structure, establishing the construction structure strain model and displaying it represents the process of the image display function.

[0085] The working principle and beneficial effects of the above technical solution are as follows: a virtual construction structure is established according to the construction structure drawings through the intelligent display module, and then the strain data of each reinforced concrete component is marked on the virtual construction structure to provide a more intuitive and well-prepared address display. A graphical display is performed according to the designed address information to clearly show which part, which component, and the specific part of the component has stress or strain conditions.

[0086] Example 3

[0087] Based on Example 1, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden further includes:

[0088] A storage module is used to obtain the sensor data at the current moment, the strain information of each reinforced concrete component at the current moment, and the alarm status at the current moment, and to establish a current information package at the corresponding moment;

[0089] Connecting the current information packet with the historical information packet to obtain the target information packet;

[0090] The target information packet is edited into an unmodifiable mode and stored.

[0091] In this example, the current information package consists of the sensor data at the current moment, the strain information of each reinforced concrete component at the current moment, and the alarm status at the current moment. When the alarm is in progress at the current moment, the alarm status is the working state, otherwise it is the standby state.

[0092] In this example, the target information package represents a collection of information including all historical strain information and historical alarm status of a reinforced concrete component.

[0093] The working principle and beneficial effects of the above technical solution: In order to facilitate relevant personnel to review construction records, the storage module obtains and stores the current sensor data, strain information of each reinforced concrete component and alarm status in real time, thereby facilitating data query or data verification and realizing intelligent safety warning.

[0094] Example 4

[0095] Based on Example 1, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the transmission module includes:

[0096] The line analysis unit is used to send detection signals to the acquisition module and the detection module respectively by using the wired transmission line to determine whether the wired transmission line is interrupted;

[0097] If yes, the sensor data of the acquisition module is acquired by wireless transmission, and then the sensor data is transmitted to the detection module; otherwise, the sensor data of the acquisition module is acquired by wired transmission, and then the sensor data is transmitted to the detection module;

[0098] A wired transmission unit, used for establishing a wired transmission path;

[0099] The wireless transmission unit is used to establish a wireless transmission link.

[0100] The working principle and beneficial effects of the above technical solution: In order to achieve the purpose of data transmission, two transmission paths, wired transmission and wireless transmission, are set up on site. Generally, wired transmission is used to save costs. However, in order to avoid the inability to transmit data when the wired transmission path fails, the line analysis unit detects the wired transmission path and switches to wireless transmission when the wired transmission path fails, avoiding data interruption and achieving effective transmission.

[0101] Example 5

[0102] Based on Example 1, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the monitoring module includes:

[0103] an analysis unit, configured to draw a strain curve corresponding to each reinforced concrete component based on the sensing data;

[0104] a debugging unit, configured to obtain a stress limit value corresponding to each reinforced concrete component, obtain a curve threshold value of each strain curve, analyze each strain curve to obtain an extension direction corresponding to each strain curve, draw an extension line according to the extension direction, and mark a threshold point corresponding to the curve threshold value on the extension line;

[0105] The monitoring unit is used to establish a corresponding stress limit range for each reinforced concrete component according to the stress limit value, mark the stress limit range on the corresponding extension line, obtain the current stress point corresponding to each strain curve, and when the current stress point is within the stress limit range, determine whether the stress value of the corresponding reinforced concrete component reaches the stress limit range.

[0106] In this example, one strain curve corresponds to one reinforced concrete member;

[0107] In this example, the strain curve represents the stress variation curve of the reinforced concrete component at different times;

[0108] In this example, the stress limit value represents the maximum stress value that each reinforced concrete member can withstand;

[0109] In this example, the curve threshold value indicates the value at which the strain curve is prone to fracture when the stress of reinforced concrete reaches the limit value due to the limited bearing capacity of reinforced concrete, that is, the maximum value of the strain curve;

[0110] In this example, the extension direction indicates the angle formed by the strain curve along the current angle and the coordinate system of the strain curve;

[0111] In this example, the threshold point represents the point corresponding to the threshold value of the curve;

[0112] In this example, the beneficial effects of the work performed by the debugging unit are as follows: due to the certain delay in data transmission and the limited bearing capacity of reinforced concrete components, in order to prevent the reinforced concrete components from being subjected to excessive pressure and unable to be restored to their original state, a threshold point is obtained on the strain curve to obtain the maximum stress of the reinforced concrete components, which facilitates the establishment of a stress limit range during subsequent testing work;

[0113] In this example, the stress limit range refers to a limit range established based on the stress limit value of the corresponding reinforced concrete component. For example, the stress limit value of a reinforced concrete component is 100 Pa. Since the reinforced concrete component will break when the stress reaches 100 Pa, causing it to be unable to be used normally, in order to avoid its breakage and deformation, a stress limit range is established for it, and the stress limit range is [90, 100].

[0114] In this example, the extension line represents a line between the current curve end and the curve threshold of the strain curve.

[0115] For example, the strain curve of reinforced concrete components is drawn by the analysis unit based on the sensor data. Figure 4 As shown, the debugging unit then obtains the stress limit value of the reinforced concrete component as 90Pa, so the curve threshold of the strain curve is 90, and then the strain curve is extended until the strain curve intersects with 90. At this time, the curve threshold can be obtained, and then the monitoring unit establishes the stress limit range of the reinforced concrete component [87, 90]. At this time, the current stress point is 85, which is not within the stress limit range.

[0116] The working principle and beneficial effects of the above technical solution are as follows: in order to monitor the stress of each reinforced concrete component in real time, a strain curve is drawn according to the sensing data, and then the curve threshold is marked on the strain curve. Then, an extension line is made to obtain the threshold point of the strain curve. Finally, a stress limit range is established by the monitoring unit according to the stress limit value of each reinforced concrete component. Therefore, it is possible to judge whether the reinforced concrete component has reached the stress limit based on the positional relationship between the current stress point and the stress limit range. This not only protects the reinforced concrete components, but also prevents the reinforced concrete components from being deformed and affecting normal use.

[0117] Example 6

[0118] Based on Example 1, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the alarm module includes:

[0119] The sound and light alarm unit is used to give sound and light alarm when the stress value of the reinforced concrete component reaches the stress limit range;

[0120] A remote alarm unit, configured to generate alarm information and transmit the alarm information to a designated remote terminal for display;

[0121] Manual alarm unit for technicians to activate the alarm.

[0122] In this instance, technicians can manually issue an alarm based on the monitoring data information;

[0123] In this example, after the alarm is triggered, the alarm module can transmit the alarm information to the mobile phone user and the user of the networked platform system through the wireless system;

[0124] In this example, after receiving the early warning, personnel at the construction site should stop construction after seeing the sound and light alarms on site. The on-duty manager in the duty room should first stop construction at the alarm system location according to the emergency plan, and at the same time take emergency safety measures such as reducing overload and reinforcement. Managers on mobile phones and computers should take various safety management measures according to the emergency plan.

[0125] The working principle and beneficial effects of the above technical solution are as follows: in order to avoid accidents, when the stress value of the reinforced concrete component reaches the stress limit range, the alarm module will sound an alarm to remind relevant personnel to start the emergency plan as soon as possible. Moreover, during daily construction, if relevant personnel find abnormal phenomena, they can use the manual alarm unit to sound an alarm, thereby achieving the purpose of diversifying the alarm methods.

[0126] Example 7

[0127] Based on Example 2, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, wherein the intelligent display module includes:

[0128] A model building unit, configured to obtain construction structure drawings and build a virtual construction structure according to the construction structure drawings;

[0129] an information processing unit, configured to obtain strain information corresponding to each reinforced concrete component and a generation time corresponding to each strain information, and obtain a hysteresis amount of each strain information based on a time difference between the generation time and a current time;

[0130] Establishing a data prediction model, inputting each strain information into the data prediction model, and predicting the predicted strain information of each reinforced concrete component at the current moment according to the hysteresis corresponding to each strain information;

[0131] A data processing unit is used to analyze the predicted strain information and obtain the strain data corresponding to each reinforced concrete component;

[0132] The data marking unit is used to mark the strain data on the virtual reinforced concrete component corresponding to the virtual construction structure.

[0133] In this example, the generation time of the strain information is unique. One strain information corresponds to one generation time, but multiple strain information can be generated at one generation time.

[0134] In this example, the time difference refers to the difference between the generation time and the current time. For example, if the generation time of strain information A is 16:01:32 on the same day and the current time is 16:04:03, then the time difference is 3 minutes and 31 seconds.

[0135] In this example, the predicted strain information represents the result of predicting the actual strain information at the current moment based on the strain information and the lag amount of the strain information at the current moment. For example, if the current time is 09:03 and the latest strain result obtained at this time was generated at 08:59 on the same day, then the lag amount is 4, and a prediction can be made to obtain the predicted strain information at the current moment.

[0136] Take an example to verify this instance: obtain the construction structure drawing T, establish a virtual construction structure S based on the construction structure drawing T, and then use the information processing unit to obtain the strain information k corresponding to each reinforced concrete component, as well as the generation time s corresponding to each strain information, and then generate the lag ps of each strain information k based on the current time p. In this way, the strain information can be input into the data prediction model to obtain the predicted strain information, and then the data processing unit obtains the strain data j of each reinforced concrete component based on the predicted strain information. Finally, the data annotation unit annotates the strain data on the virtual construction structure S.

[0137] The working principle and beneficial effects of the above random number scheme are as follows: In order to facilitate relevant personnel to view the current strain data of each reinforced concrete component, a virtual construction structure is established according to the construction structure drawings, and then the strain information is predicted to obtain the strain data of each reinforced concrete. Finally, the strain data is marked in the virtual construction component to clearly show the stress or strain situation of which part, which component, and the specific part of the component.

[0138] Example 8

[0139] Based on Example 4, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the line analysis unit includes:

[0140] A testing component, configured to send detection signals to the acquisition module and the detection module respectively, to obtain a first feedback signal from the acquisition module and a second feedback signal from the detection module;

[0141] an analysis component, configured to perform fast Fourier processing on the first feedback signal and the second feedback signal to obtain a first spectrum signal and a second spectrum signal, and extract a first frequency point in the first spectrum signal and a second frequency point in the second spectrum signal, respectively;

[0142] Obtaining an information point on the detection signal, and obtaining detection information corresponding to the information point;

[0143] A judgment component is used to use the detection information to traverse the first frequency point and the second frequency point to obtain the first information contained in the first spectrum signal and the second information contained in the second spectrum signal. When the first information amount of the first information or the second information amount of the second information is less than the preset information amount, it is determined that the wired transmission mode is interrupted.

[0144] In this example, the detection signal represents a short-time signal used to detect the on / off state of a transmission mode, and the short-time signal contains a plurality of continuous data;

[0145] In this example, the signal fed back by the acquisition module to the test component is the first feedback signal, and the signal fed back by the detection module to the test component is the second signal. The terms "first" and "second" are only used to distinguish the two feedback signals and do not have a comparison function.

[0146] In this example, the spectrum signal represents a representation of the feedback signal after fast Fourier processing is performed and then input into the frequency domain;

[0147] In this example, the frequency point represents the point where the absolute frequency value of the spectrum signal is located;

[0148] In this example, the first information represents information from the detection signal contained in the first spectrum signal;

[0149] In this example, the second information represents information from the detection signal contained in the second spectrum signal;

[0150] In this example, the information amount refers to the amount of detection information contained in the spectrum signal.

[0151] The working principle and beneficial effects of the above technical solution: In order to avoid data transmission interruption while ensuring data transmission efficiency, the test component in the line analysis unit sends detection signals to the acquisition module and the detection module respectively, and analyzes whether the wired transmission mode is interrupted based on the feedback signals of the two modules. In this way, not only can the line be detected in real time and the problems in the line be analyzed, but also the wired transmission mode can be maximized to improve transmission efficiency. In addition, the use of wired transmission mode for data transmission can reduce transmission costs.

[0152] Example 9

[0153] Based on Example 4, the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the line analysis unit includes:

[0154] a switching component, configured to obtain all wireless links between the acquisition module and the detection module when the wired transmission mode is interrupted;

[0155] Obtaining a transmission threshold corresponding to each wireless link respectively, and sorting the wireless links in descending order based on the transmission threshold;

[0156] A target wireless link with a maximum transmission threshold is extracted from the sorting results, and a transmission path between the acquisition module and the detection module of the target wireless link is switched to the target wireless link.

[0157] In this example, the transmission threshold represents the maximum amount of data that can be transmitted per unit time when the wireless link performs data transmission.

[0158] The working principle and beneficial effects of the above technical solution are as follows: In order to avoid data transmission failure caused by interruption of wired transmission, in this case, the switching component obtains several wireless links between the acquisition module and the detection module, and then selects a link with the largest transmission threshold as the target wireless link, and finally uses the target wireless link to realize data intercommunication between the acquisition module and the detection module.

[0159] Example 10

[0160] Based on Example 1, the intelligent monitoring safety warning system for reinforced concrete structure construction overburden:

[0161] There are multiple alarm modules, which are respectively set up at the construction site, the duty room, the mobile phones of relevant personnel, and the computers of relevant personnel.

[0162] The working principle and beneficial effects of the above technical solution are as follows: After receiving the early warning, the personnel at the construction site should stop construction after seeing the sound and light alarm on site. The on-duty management personnel in the duty room should first stop the construction at the location of the alarm system according to the emergency plan, and at the same time take emergency safety measures such as reducing overload and reinforcement. The managers on the mobile phone and computer sides should take various safety management measures according to the emergency plan.

[0164] Based on Example 1, in the intelligent monitoring safety and early warning system for reinforced concrete structure construction overburden, the monitoring module is further used to:

[0165] Obtain the unit volume compressive strength standard value corresponding to each reinforced concrete component, denoted as ki;

[0166] Analyze the strain information to obtain the current strain corresponding to each reinforced concrete component, denoted as Bi
