Description

Technical Field

[0001] This invention belongs to the field of pile foundation construction technology, specifically relating to a quality control and real-time monitoring system for pile foundation concrete. Background Technology

[0002] In modern infrastructure construction, pile foundation construction is widely used in various foundation treatment projects such as bridges, high-rise buildings, and hydraulic structures.

[0003] Typically, pile foundation construction includes steps such as drilling, fabricating and placing the reinforcing cage, cleaning the borehole, and pouring the pile foundation concrete. Because pile foundations are concealed works, it is difficult to monitor their quality and safety after the above-ground construction has begun. Therefore, strict control over construction techniques and materials is essential during pile foundation construction to ensure the quality meets requirements. Pile foundation concrete, as the core material in pile foundation construction, is not only the "underground backbone" of the building but also a crucial element in project risk and cost control. Its construction must simultaneously meet four key requirements: mechanical performance, geological compatibility, quality controllability, and economic rationality. Failure in any of these areas can trigger a chain of risks.

[0004] In pile foundation construction, ready-mixed concrete is typically used to improve construction efficiency, environmental friendliness, and economy. Ready-mixed concrete refers to concrete mixtures that are centrally mixed and processed at a batching plant and then transported to the construction site. It is widely used in the construction industry due to its advantages such as low material consumption, high efficiency, low cost, and environmental friendliness. However, during the production and transportation of ready-mixed concrete at batching plants, quality is difficult to guarantee due to profit motives or a lack of effective supervision. Construction accidents caused by defects in ready-mixed concrete occur frequently. Furthermore, as pile foundation construction is a concealed project, the pile concrete is buried deep underground after pouring. During construction, various responsible parties often take chances or neglect supervision, allowing substandard ready-mixed concrete to easily enter the pile foundation construction project, leading to quality and safety accidents. Summary of the Invention

[0005] To address the problems mentioned in the background art, this invention provides a quality control and real-time monitoring system for pile foundation concrete. By automatically matching supply and demand between pile foundation projects and mixing sites, and randomly assigning testing units, it can not only achieve two-way real-time monitoring of concrete leaving the factory and entering the site to prevent unqualified concrete from flowing into the pile foundation construction site, but also automatically judge and issue different warning messages to remind different responsible parties to promptly investigate the quality and safety risks of concrete and take corresponding control measures.

[0006] The present invention is achieved through the following technical solution.

[0007] A quality control and real-time monitoring system for pile foundation concrete includes a data storage unit and a human-computer interaction terminal. It is characterized by further including: a supply-demand matching module, a detection allocation module, and a quality monitoring module, each bound to several detection units with a unique detection number. The supply and demand matching module includes a function to compare the concrete demand information of the pile foundation project with the concrete supply information of the mixing plant, and to group the pile foundation projects and mixing plants that are matched in supply and demand into the same supply and demand group to obtain supply and demand grouping information; and to calculate the theoretical transportation time of concrete from the mixing plant to the pile foundation project based on the regional location of the pile foundation projects and mixing plants in each supply and demand group. The detection allocation module is used to randomly select a detection number from the detection numbers of all detection units without repetition and allocate it to the pile foundation project and mixing site of each supply and demand group according to the supply and demand group information, so as to obtain the detection allocation information. The detection units are distributed and configured at the mixing sites and pile foundation project sites of each supply and demand group according to the detection allocation information. They are used to quickly test samples of concrete transported by cement trucks in each supply and demand group before leaving the factory and entering the site, so as to obtain the license plate number of the sampling vehicle, the sampling time, the detection location and the detection results of the concrete leaving the factory and entering the site for each supply and demand group. The quality monitoring module includes: based on the testing allocation information, by identifying the testing number, it retrieves the license plate number, sampling time, testing location, and testing results of the sampling vehicles that leave the factory and arrive at the site for the corresponding supply and demand group of concrete.

If the location of the test is not within the corresponding area or / and the test results are inconsistent with the concrete supply information, an alarm message indicating abnormal factory testing location or / and abnormal factory concrete quality will be sent to the human-machine interface terminal, and the corresponding sampling vehicle license plate number will be sent to the factory access control system as a prohibited vehicle license plate number. If the location of the test is within the corresponding area and the test results are consistent with the concrete supply information, the corresponding sampling vehicle license plate number will be sent to the factory access control system as a permitted vehicle license plate number. This system is used to determine whether the concrete arrival inspection location is within the pile foundation project area, and to calculate the time difference between the concrete leaving the factory and the arrival sampling time. It also determines whether the time difference is within the theoretical transportation time. If the inspection location is not within the corresponding area or / and the time difference is not within the theoretical transportation time, an alert message indicating an abnormal arrival inspection location or / or abnormal sampling timing is sent to the human-machine interface. Simultaneously, the corresponding sampling vehicle license plate number is sent as a prohibited vehicle license plate number to the entry access control system. If the inspection location is within the corresponding area and the time difference is within the theoretical transportation time, it further determines whether the concrete arrival inspection results meet the concrete requirements of the pile foundation project. If the inspection results do not meet the concrete requirements, an equipment malfunction alert message is sent to the human-machine interface, and the corresponding sampling vehicle license plate number is sent as a prohibited vehicle license plate number to the entry access control system. If the inspection results meet the concrete requirements, the corresponding sampling vehicle license plate number is sent as a permitted vehicle license plate number to the factory exit access control system. The factory exit access control system and the site entry access control system are used to identify the license plate number of the cement tanker truck. If the license plate number is a license plate number that allows passage, the cement tanker truck will be allowed to pass. If the license plate number is a license plate number that prohibits passage, the cement tanker truck will be prohibited from passing.

[0009] Preferably, the quality monitoring module further includes: after issuing a warning message, retrieving the corresponding risk warning information and sending it synchronously to the human-computer interaction terminal.

[0010] Preferably, the human-machine interface includes: a module for inputting concrete demand information and the regional location of the pile foundation project and sending it to the supply and demand matching module; a module for inputting concrete supply information and the regional location of the mixing station and sending it to the supply and demand matching module; a module for inputting the testing unit's testing number and sending it to the testing allocation module; and a module for responding to warning messages regarding abnormal factory testing locations, abnormal factory concrete quality, abnormal on-site testing locations, abnormal sampling timing, and equipment malfunctions.

[0012] Preferably, the detection unit is configured with a rapid detection component, a timing module, a positioning module, and a communication module. The rapid detection component is used to perform on-site rapid detection of concrete leaving the factory and arriving at the site in real time to obtain the detection results. The timing module and the positioning module are used to obtain the sampling time and detection location during the detection, respectively. The communication module is used to read the detection results in real time and automatically bind the detection number, as well as add the sampling vehicle license plate number, sampling time, and detection location, and package and send them to the quality monitoring module and the data storage unit.

[0013] Preferably, the rapid detection component includes a chloride ion measuring unit for rapidly detecting the chloride ion content of concrete, a slump measuring unit for rapidly detecting the slump of concrete, a concrete strength measuring unit for rapidly detecting the strength grade of concrete, and an air content measuring unit for rapidly detecting the air content of concrete. The detection results include chloride ion content, slump, strength grade, and air content.

[0014] Preferably, the detection unit is further equipped with a camera module, which is used to collect detection video images of concrete leaving the factory and arriving at the site. The detection video images are packaged in the detection results and sent to the quality monitoring module and the data storage unit through the communication module. The quality monitoring module also includes analyzing the detection video images of concrete leaving the factory and arriving at the site to determine whether the detection sampling location is normal, and sending the judgment result to the human-machine interaction terminal.

[0015] Preferably, the quality monitoring module further includes a function to analyze and calculate the dynamic change information of the test results under different sampling times based on the sampling time and test results of concrete leaving the factory and arriving at the site in each supply and demand group. When the dynamic change information is continuously rising / falling, or the change exceeds the threshold, an alarm message indicating abnormal concrete change in the supply and demand group is issued to the human-machine interface terminal.

[0016] Preferably, the detection allocation module further includes a new unique detection number for the detection units configured for the mixing stations and pile foundation projects in each supply and demand group after the supply and demand relationship between the mixing stations and pile foundation projects in each supply and demand group is completed.

[0018] (1) In this invention, the supply and demand relationship between the pile foundation project and the mixing plant is established by automatically matching the concrete demand information of the pile foundation project with the concrete supply information of the mixing plant through the supply and demand matching module. This supply and demand matching process is fair, transparent and reasonable, and can prevent human intervention in buying and selling, and can effectively ensure the supply and demand quality and safety of ready-mixed concrete.

[0019] (2) In this invention, the detection unit is bound to a unique detection number and is randomly assigned by the supply and demand group through the detection allocation module, which can avoid the possibility of the mixing site and the pile foundation project party falsifying and tampering with the detection data through the detection equipment.

[0020] (3) In this invention, the concrete is inspected from both the factory and the site by randomly assigned testing units to obtain the sampling vehicle license plate number, thereby enabling timely detection and control of substandard concrete to prevent it from flowing into the pile foundation project site. At the same time, when the testing unit obtains the test results, it also obtains the sampling time and testing location information, and compares them with the theoretical transportation time and the regional location of the pile foundation project or mixing station. This allows for automatic judgment of the testing process and whether the testing unit, cement truck and other equipment are abnormal from both time and location dimensions. At the same time, relevant warning information is issued to remind relevant supervisory personnel to conduct relevant supervision and inspection, and to conduct targeted investigations of quality and safety risks.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the following embodiments are merely illustrative examples of the present invention, and the scope of protection of the present invention is not limited thereto. The described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0023] Please refer to the following: A quality control and real-time monitoring system for pile foundation concrete. Figure 1 and Figure 3It includes a data storage unit, a human-machine interface terminal, a factory access control system, an entrance access control system, a supply and demand matching module, a testing and allocation module, and a quality monitoring module, each of which is bound to several testing units with a unique testing number. The supply and demand matching module includes a function to compare the concrete demand information of pile foundation projects with the concrete supply information of mixing plants, group the pile foundation projects and mixing plants that are matched for supply and demand into the same supply and demand group, obtain supply and demand grouping information, and send it to the detection and allocation module and data storage unit; it is used to calculate the theoretical transportation time of concrete from the mixing plant to the pile foundation project based on the regional location of the pile foundation projects and mixing plants in each supply and demand group, and send the theoretical transportation time of each supply and demand group to the quality monitoring module; wherein, the theoretical transportation time is calculated reasonably based on the regional location of the pile foundation projects and mixing plants in the supply and demand group, the driving speed of cement trucks, and considering different transportation routes, the number of traffic lights, and the time required for rapid testing of concrete samples when leaving the factory, and its minimum and maximum values ​​are calculated reasonably; The detection allocation module is used to randomly select a detection number from the detection numbers of all detection units without repetition and allocate it to the pile foundation project and mixing site of each supply and demand group according to the supply and demand group information, thereby obtaining the detection allocation information; The testing units are stored in a monitoring center, which can be a government regulatory department or a third-party regulatory agency. After obtaining the testing allocation information, the monitoring center distributes and configures the testing units with corresponding testing numbers to the mixing sites and pile foundation project sites of the supply and demand groups. These units are used to quickly test samples of concrete transported by cement trucks in each supply and demand group before they leave the factory and arrive at the site. This allows the center to obtain the license plate number of the sampling vehicle, the sampling time, the testing location, and the testing results of the concrete at the time of leaving the factory and arriving at the site. These results are then sent to the quality monitoring module and the data storage unit. Specifically, the ready-mixed concrete produced at the mixing site is transported out by cement trucks before leaving the factory, and the ready-mixed concrete produced at the mixing site is transported into the pile foundation project site by cement trucks before arriving at the site. The license plate number of the sampling vehicle is the same as the license plate number of the cement truck transporting the concrete. The quality monitoring module includes: It is used to retrieve the license plate number, sampling time, testing location and testing results of the sampling vehicles that leave the factory and arrive at the site for the corresponding supply and demand group by identifying the testing number based on the testing allocation information. This system is used to compare the location of concrete leaving the factory with the location of the mixing plant to determine whether the concrete leaving the factory is within the mixing plant's location area. It also compares the test results with the concrete supply information to determine whether the test results match the concrete supply information. If the location of the test is not in the corresponding location area or / and the test results do not match the concrete supply information, an alert message indicating abnormal factory testing location or / and abnormal factory concrete quality is sent to the human-machine interface. The corresponding sampling vehicle license plate number is also sent to the factory access control system as a prohibited vehicle license plate number. If the location of the test is in the corresponding location area and the test results match the concrete supply information, the corresponding sampling vehicle license plate number is sent to the factory access control system as a permitted vehicle license plate number. This system compares the location of the concrete arrival inspection with the location of the pile foundation project to determine if the inspection location is within the project's area. It also calculates the time difference between the concrete's factory departure and arrival sampling times, checking if this time difference is within the theoretical transportation time. If the inspection location is not within the corresponding area or / and the time difference is not within the theoretical transportation time, an alert is sent to the human-machine interface indicating an abnormal arrival inspection location or / or abnormal sampling timing. Simultaneously, the corresponding sampling vehicle's license plate number is sent as a prohibited license plate number to the access control system. If the inspection location... If the time difference is within the theoretical transportation time in the corresponding location area, the test results of the incoming concrete are further compared with the concrete demand information of the pile foundation project to determine whether the test results of the incoming concrete meet the concrete demand information of the pile foundation project. If the test results do not meet the concrete demand information, an equipment abnormality warning message is sent to the human-machine interface terminal, and the corresponding sampling vehicle license plate number is sent as a prohibited vehicle license plate number to the access control system. If the test results meet the concrete demand information, the corresponding sampling vehicle license plate number is sent as a permitted vehicle license plate number to the exit access control system. The factory exit access control system and the site entry access control system are commonly used vehicle access control systems in the prior art. The factory exit access control system and the site entry access control system are respectively set at the entrance and exit of the mixing plant and the pile foundation project site. The factory exit access control system and the site entry access control system are used to identify the license plate number of the cement tanker truck. If the license plate number is a license plate number that allows passage, the cement tanker truck is allowed to pass; if the license plate number is a license plate number that prohibits passage, the cement tanker truck is prohibited from passing. Specifically, the passage and prohibition operations are achieved by controlling the motor to raise or lower the barrier or extend the barrier through the factory exit access control system and the site entry access control system. Furthermore, in a preferred embodiment, the quality monitoring module further includes: after issuing a warning message, retrieving the corresponding risk warning information and sending it synchronously to the human-machine interface terminal, so that the monitoring center can quickly investigate the quality and safety risks of concrete; Specifically, the risk warning information corresponding to abnormal factory testing locations and abnormal incoming testing locations includes: "Incorrect testing unit configuration" and "Manual transfer of testing units". When the quality monitoring module issues a warning message about abnormal factory / incoming testing locations, the following risks or problems may usually exist: First, incorrect testing unit configuration, that is, the regulatory center has not accurately issued the testing form according to the testing allocation information; Second, manual transfer of testing units, that is, the testing unit has been manually transferred after the configuration has been issued in order to cheat the testing. Specifically, the risk warnings corresponding to abnormal sampling timing include: "theft during transportation," "untimely sampling," and "traffic disruption." Since sampling occurs when cement trucks transport concrete from the factory to the site, under normal sampling timing, the time difference between the sampling time at the factory and the sampling time at the site represents the actual transportation time of the concrete, which should fall within the theoretical transportation time. Therefore, when the quality monitoring module issues a warning message about abnormal sampling timing, the following risks or problems may exist: First, theft during transportation, i.e., theft of concrete during transportation, leading to a change in the actual transportation time; second, untimely sampling, i.e., failure to sample in a timely manner before the cement truck transports concrete from the factory and / or before it arrives at the site; third, traffic disruption, i.e., cement truck malfunction or traffic congestion, significantly increasing transportation time, causing partial solidification of the concrete and reduced fluidity. Specifically, the risk warning information corresponding to the equipment malfunction warning message includes: "Detection unit failure" and "Cement tanker truck failure". When the concrete factory test results are normal, since there are no abnormalities in the sampling timing and testing positioning of the concrete at the factory and on site, the on-site test results should be normal. If the on-site test results are abnormal, it may be due to a malfunction of the detection unit located in the pile foundation project or mixing site, or the cement tanker not rotating or the rotation speed not meeting the standard during transportation. Therefore, when the quality monitoring module issues an equipment malfunction warning message, the following risks or problems may exist: first, detection unit failure; second, cement tanker truck failure.

[0024] Furthermore, in a preferred embodiment, the concrete demand information for the pile foundation project includes the pile foundation project name, pile foundation project number, regional location of the pile foundation project, concrete requirement grade, demand quantity, demand time, and budgeted price; correspondingly, the concrete supply information includes the mixing plant name, mixing plant number, regional location of the mixing plant, concrete supply grade, supply quantity, supply time, and selling price; when matching supply and demand, the concrete supply grade should be the same as the concrete requirement grade, the supply quantity should be greater than the demand quantity, the selling price should be less than or equal to the budgeted price, and the supply time should meet the demand time.

[0025] Furthermore, in a preferred embodiment, please refer to Figure 2The detection unit is equipped with a rapid detection component, a timing module, a positioning module, and a communication module. The rapid detection component is used to conduct on-site testing of concrete leaving the factory and arriving at the site in real time to obtain test results. The timing module and positioning module are used to obtain the sampling time and detection location during the test, respectively. The communication module is used to read the test results in real time and automatically bind the test number, as well as add the sampling license plate number. The sampling time and detection location are packaged in a standard JSON / XML structure and sent to the quality monitoring module and data storage unit. The sampling license plate number can be manually entered or implemented by adding a license plate number recognition module to the detection unit. The license plate number recognition module is a mature technology used in vehicle access control systems, which will not be described in detail here. The communication module supports 4G / 5G cellular network communication and can be equipped with WiFi, Bluetooth, and Beidou short message communication functions. The communication module has an embedded microprocessor for data integration and encoding. After each test is completed, the communication module automatically triggers a data transmission request and supports breakpoint retransmission and cache retransmission logic.

[0026] According to the national standard "Ready-Mixed Concrete" (GB / T 14902) and industry specifications, ready-mixed concrete must be tested for the following core indicators before leaving the factory: slump, strength grade, chloride ion content, and air content. Further, in a preferred embodiment, the rapid testing component includes a chloride ion measuring unit for rapidly detecting the chloride ion content of the concrete, a slump measuring unit for rapidly detecting the slump of the concrete, a concrete strength measuring unit for rapidly detecting the strength grade of the concrete, and an air content measuring unit for rapidly detecting the air content of the concrete. The test results include chloride ion content, slump, strength grade, and air content; the chloride ion measuring unit, slump, strength grade, and air content are all tested. The slump measurement unit, concrete strength measurement unit, and air content measurement unit should be waterproof and dustproof, suitable for outdoor pile foundation construction environments. Specifically, the chloride ion measurement unit can use a portable instrument based on the ion-selective electrode method, such as the NJCL-H type rapid chloride ion content analyzer; the slump measurement unit and concrete strength measurement unit can use the JY-FCT102 type fresh concrete comprehensive analyzer, which can automatically measure and calculate slump and predict 28-day compressive strength through rotational resistance; the air content measurement unit can use the LA-316 type concrete air content analyzer. Using the above-mentioned measurement units, sampling and rapid testing of slump, strength grade, chloride ion content, and air content can be completed within 5 minutes.

[0027] Furthermore, in a preferred embodiment, the detection unit is also equipped with a camera module, which is used to acquire inspection video images of concrete leaving the factory and arriving at the site. The inspection video images are packaged in the inspection results and sent to the quality monitoring module and data storage unit through the communication module. The quality monitoring module also includes analyzing the inspection video images of concrete leaving the factory and arriving at the site to determine whether the inspection sampling location is normal, and sending the judgment result to the human-machine interface terminal. Typically, the inspection sampling locations for concrete leaving the factory and arriving at the site are at the feed hopper and discharge chute of the cement truck, respectively. The quality monitoring module can identify the feed hopper and discharge chute of the cement truck in the inspection video images to determine whether the sampling location is normal. To improve the accuracy of identification, other identification markers can also be set at the feed hopper and discharge chute of the cement truck.

[0028] Furthermore, in a preferred embodiment, the quality monitoring module further includes an ability to analyze and calculate the dynamic changes in test results at different sampling times based on the sampling time and test results of concrete leaving the factory and arriving at the site in each supply and demand group. When the dynamic changes show a continuous increase / decrease, or the change exceeds a threshold, an alert message indicating abnormal concrete changes in that supply and demand group is sent to the human-machine interface. This helps the pile foundation project owner and the mixing plant owner to anticipate abnormalities and improve the initiative and timeliness of on-site problem response. For example, for pile foundation project N1 and mixing plant Z1, which have established a supply and demand relationship, during the concrete factory inspection at mixing plant Z1, the testing unit randomly sampled four transport trucks on the same day, with sampling times of 8:30, 9:45, 10:40, and 11:45. The compressive strength test results at these sampling times were 34.2 MPa, 33.1 MPa, 32.3 MPa, and 30.4 MPa, respectively. MPa. The quality monitoring module analyzes and calculates the dynamic changes of test results at different sampling times. If it finds that the compressive strength is continuously decreasing at different sampling times, it will issue an alarm message to the human-machine interface indicating abnormal changes in the concrete of the supply and demand group. After receiving the alarm message, the relevant management personnel of the monitoring center and the mixing plant can promptly check the raw materials, production measurement, construction process and other aspects of the mixing plant.

[0029] Furthermore, in a preferred embodiment, the human-machine interface includes: a module for inputting concrete demand information and the regional location of the pile foundation project and sending it to the supply-demand matching module; a module for inputting concrete supply information and the regional location of the mixing plant and sending it to the supply-demand matching module; a module for inputting the testing unit's testing number and sending it to the testing allocation module; and a module for responding to warning messages regarding abnormal factory testing locations, abnormal factory concrete quality, abnormal on-site testing locations, abnormal sampling timing, and equipment malfunctions. Specifically, the human-machine interface can respond to different warning messages in ways including but not limited to text, sound, images, and video. For example, when the monitoring terminal receives a warning message about an abnormal factory testing location, it can display the text "mixing plant number + abnormal factory testing location" on the human-machine interface and broadcast an audio message.

[0030] Furthermore, in a preferred embodiment, the testing allocation module further includes a new unique testing number for binding the testing units issued to the mixing stations and pile foundation projects of each supply and demand group after the supply and demand relationship between the mixing stations and pile foundation projects in each supply and demand group is completed; at the same time, the issued testing units should be returned to the monitoring center in a timely manner.

[0031] Furthermore, in a preferred embodiment, the system of the present invention also includes a cloud database. The concrete demand information of the pile foundation project, the concrete supply information of the mixing plant, the supply and demand group information, the theoretical transportation time of each supply and demand group, the testing allocation information, and the sampling time, testing location, and testing results of concrete leaving the factory and arriving at the site for each supply and demand group are synchronously uploaded to the cloud database when stored in the data storage unit. The data stored in the data storage unit and the cloud database supports multi-dimensional querying and statistics by pile foundation project, mixing plant name or number, supply and demand group name or number, testing number, sampling time, testing location, testing results, etc.

[0032] Furthermore, in a preferred embodiment, the system of the present invention further includes a data analysis and output module. This module includes functions for: retrieving all test results from the data storage unit, filtering out test results whose location matches the target mixing station's area location, and performing analysis and statistics to generate a concrete production quality report for the target mixing station; and retrieving the sampling time, test location, and test results of the corresponding supply and demand group's concrete leaving the plant and arriving at the site based on the test allocation information and by identifying the test number, to generate a concrete supply and demand quality report for the target supply and demand group. Additionally, the data in the above reports can be graphically displayed using existing visualization components such as ECharts or D3.js to draw parameter trend curves, and supports data point highlighting, fluctuation range labeling, and annotation functions. Example 2

[0033] This embodiment is a further illustration of a quality control and real-time monitoring system for pile foundation concrete according to Embodiment 1, and aims to provide more detailed technical details or demonstrate the working method of the system of the present invention: Take the pile foundation project in area A as an example.

[0034] The monitoring center in region A houses 52 testing units, each initially bound with a unique testing number: J1, J2, J3, ..., J50, J51, J52. Region A currently has 8 pile foundation projects under construction, numbered Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8, and 13 mixing plants, numbered N1, N2, ..., N11, N12, N13. Managers of each pile foundation project and each mixing plant respectively input concrete demand information through the pile foundation project terminal and the mixing plant terminal. Concrete supply information is sent to the supply-demand matching module. The supply-demand matching module compares the concrete demand information of the pile foundation projects with the concrete supply information of the mixing plants, grouping the pile foundation projects and mixing plants in the same supply-demand group to obtain supply-demand grouping information. Simultaneously, the supply-demand matching module calculates the theoretical transportation time for concrete from the mixing plant to the pile foundation project based on the regional location of the pile foundation projects and mixing plants in each supply-demand group. The specific supply-demand grouping information and theoretical transportation time are shown in the table below:

[0035] For ease of understanding, the supply and demand grouping information above only illustrates a one-to-one matching scenario between pile foundation projects and mixing plants. In other cases, it can also be a one-to-many matching scenario. During supply and demand matching, the matching is generally based on the order in which the pile foundation projects enter their concrete demand information. That is, the pile foundation projects that enter their concrete demand information first are matched first. When the concrete supply information of multiple mixing plants matches the concrete demand information of the pile foundation project, the supply and demand matching module can also select one mixing plant for matching in order of lowest price and closest distance. With the above grouping information determined, the pile foundation project establishes a supply and demand relationship with the mixing plant, the pile foundation project carries out the preliminary preparations for the pile foundation concrete pouring, and the mixing plant arranges production according to the demand time / supply time; Based on the above supply and demand grouping information, the testing allocation module randomly selects a unique testing number from the testing numbers of all testing units and assigns it to the pile foundation projects and mixing sites of each supply and demand group. This ensures a one-to-one correspondence between the pile foundation projects and mixing sites of each supply and demand group and the assigned testing unit, thereby obtaining testing allocation information. The specific testing allocation information is shown in the table below:

[0036] Based on the above testing allocation information, the testing units corresponding to the testing numbers are issued and configured by the supervision center to the pile foundation projects and mixing sites of the corresponding supply and demand groups. The testing units take samples of the concrete transported by cement tankers before leaving the factory and entering the site for rapid testing, so as to obtain the sampling vehicle license plate number, sampling time, testing location and testing results of each supply and demand group when the concrete leaves the factory and enters the site, which are bound to the corresponding testing numbers and are sent to the quality monitoring module. The following explanation uses concrete testing in the B1 supply and demand group as an example. In the B1 supply and demand group, after the concrete from mixing station N2 was delivered into cement truck with license plate number Y02, the inspector used testing unit number J2 to test the concrete in the cement truck before it left the factory. The results were obtained from the concrete sampling vehicle license plate number, sampling time, testing location, and testing results, all linked to testing unit number J2. Specifically: sampling vehicle license plate number Y02, sampling time 15:32 on May 12, 2025, testing location (a, b), and testing results: chloride ion content 0.25%, slump 185 mm, compressive strength 34.2 MPa, and air content 2.4%. Based on the testing allocation information, the quality monitoring module identifies the testing number J2, retrieves the sampling vehicle license plate number, sampling time, testing location, and testing results of the concrete leaving the factory for the B1 supply and demand group, as mentioned above. It then compares the testing locations (a, b) of the concrete leaving the factory for the B1 supply and demand group with the location area of ​​the mixing station. It also compares the testing results (chloride ion content 0.25%, slump 185 mm, compressive strength 34.2 MPa, air content 2.4%) with the concrete supply information. If it determines that the testing location is in the corresponding location area and the testing results match the concrete supply information, it sends the corresponding sampling vehicle license plate number Y02 as the release license plate number to the factory access control system. The factory access control system identifies the cement tanker truck's license plate number as Y02. If this is a license plate number that allows passage, the cement tanker truck will be released. In the B1 supply and demand group, after the cement truck with license plate number Y02 arrived at the pile foundation project Z1, the inspector used the inspection unit with inspection number J1 to conduct an on-site inspection of the concrete inside the cement truck before it entered the site. The inspection unit obtained the concrete sampling license plate number, sampling time, inspection location and inspection results associated with inspection number J1. Specifically, the sampling license plate number is Y02, the sampling time is 15:53 ​​on May 12, 2025, the inspection location is (c, d), and the inspection results are: chloride ion content 0.23%, slump 198 mm, compressive strength 33.7 MPa and air content 2.3%. Based on the testing allocation information, the quality monitoring module identifies the testing number J2 and retrieves the sampling vehicle license plate number, sampling time, testing location, and testing results of the concrete arriving at the site from the B1 supply and demand group, as mentioned above. First, it compares the testing location (c, d) of the concrete arriving at the site with the location area of ​​the pile foundation project and calculates the time difference between the concrete leaving the factory and the sampling time at the site, which is 21 minutes. It determines that the testing location (c, d) is within the location area of ​​the pile foundation project, and the time difference is within the theoretical transportation time of 19-27 minutes. Then, it further compares the testing results of the concrete arriving at the site with the concrete demand information of the pile foundation project. If the testing results meet the concrete demand information, the sampling vehicle license plate number Y02 is sent to the access control system as the release license plate number. The access control system identifies the cement truck's license plate number as Y02. If this is a license plate number that allows passage, the cement truck is released. Concrete that meets quality standards and has not shown any abnormalities during the inspection process is then delivered to the pile foundation construction site. Example 3

[0037] This embodiment further provides the concrete testing process for the B2 supply and demand group, as well as the quality control and real-time monitoring process of the system of the present invention, based on embodiment 2: In the B2 supply and demand group, after the concrete from mixing station N4 was delivered into cement truck with license plate number Y23, the inspector used testing unit number J4 to test the concrete in the cement truck before it left the factory. The results were obtained from the concrete sampling vehicle license plate number, sampling time, testing location, and testing results, all linked to testing unit number J4. Specifically: sampling vehicle license plate number Y23, sampling time 12:21 PM on May 16, 2025, testing location (e, f), and testing results: chloride ion content 0.21%, slump 182 mm, compressive strength 33.6 MPa, and air content 3.4%. Based on the testing allocation information, the quality monitoring module identifies the testing number J4, retrieves the sampling vehicle license plate number, sampling time, testing location, and testing results of the concrete leaving the factory for the B2 supply and demand group (as mentioned above), and compares the testing location (e, f) of the concrete leaving the factory for the B2 supply and demand group with the location area of ​​the mixing station. It also compares the testing results (chloride ion content 0.21%, slump 182 mm, compressive strength 33.6 MPa, air content 3.4%) with the concrete supply information. If it determines that the testing location (e, f) is not in the corresponding location area, and that the test results (chloride ion content 0.21%, slump 182 mm, compressive strength 33.6 MPa, air content 3.4%) are consistent with the concrete supply information, it issues an abnormal warning message about the factory testing location to the human-machine interface and sends the corresponding sampling vehicle license plate number Y23 as a prohibited vehicle license plate number to the factory access control system. The factory access control system identifies the cement tanker truck's license plate number as Y23. Since this is a prohibited license plate number, the system will prohibit the cement tanker truck from entering the factory. The monitoring center viewed the warning information and corresponding risk warnings about the abnormal factory testing location through the human-machine interface: "Incorrect configuration of testing unit" and "Human transfer of testing unit". After supervision and investigation, it was found that the testing unit with testing number J4 was incorrectly assigned and configured in mixing station N8 in supply and demand group B4. Example 4

[0038] This embodiment further provides the concrete testing process for the B3 supply and demand group, as well as the quality control and real-time monitoring process of the system of the present invention, based on embodiment 2: In the B3 supply and demand group, after the concrete from mixing station N5 was delivered into cement truck with license plate number Y67, the inspector used testing unit number J6 to test the concrete in the cement truck before it left the factory. The results, linked to testing unit number J6, included the concrete sampling vehicle license plate number, sampling time, testing location, and testing results. Specifically: sampling vehicle license plate number Y67, sampling time 9:15 AM on June 16, 2025, testing location (e, f), and testing results: chloride ion content 0.24%, slump 181 mm, compressive strength 32.8 MPa, and air content 3.2%. Based on the testing allocation information, the quality monitoring module identifies the testing number J6, retrieves the sampling vehicle license plate number, sampling time, testing location, and testing results of the concrete leaving the factory for the B3 supply and demand group (as mentioned above), and compares the testing location (o, p) of the concrete leaving the factory for the B2 supply and demand group with the location area of ​​the mixing station. It then compares the testing results (chloride ion content 0.24%, slump 181 mm, compressive strength 32.8 MPa, air content 3.2%) with the concrete supply information, determining that the testing location (o, p) is within the mixing station location area and that the test results (chloride ion content 0.24%, slump 181 mm, compressive strength 32.8 MPa, air content 3.2%) match the concrete supply information. Therefore, the corresponding sampling vehicle license plate number Y67 is sent to the factory access control system as the release license plate number. The factory access control system identifies the cement tanker truck's license plate number as Y67. Since this is a license plate number that can be released, the cement tanker truck is allowed to pass. In the B3 supply and demand group, after the cement truck with license plate number Y67 arrived at the Z3 pile foundation project, the inspector used the inspection unit with inspection number J5 to conduct an on-site inspection of the concrete inside the cement truck before it entered the site. The inspection unit obtained the license plate number of the concrete sample truck, the sampling time, the inspection location, and the inspection results associated with inspection number J5. Specifically, the sampling license plate number is Y67, the sampling time is 9:58 AM on June 16, 2025, the inspection location is (l, k), and the inspection results are: chloride ion content 0.22%, slump 192 mm, compressive strength 33.3 MPa, and air content 2.4%. Based on the inspection allocation information, the quality monitoring module identifies inspection number J5 and retrieves the sampling vehicle license plate number Y67, sampling time, inspection location, and inspection results for concrete arriving at the site (as mentioned above) from the B3 supply and demand group. It first compares the inspection location (l, k) of the concrete arrival with the location area of ​​the pile foundation project and calculates the time difference between the concrete's factory departure and arrival sampling time to be 43 minutes. If the inspection location (c, d) is within the location area of ​​the pile foundation project and the time difference is not within the theoretical transportation time of 20-28 minutes, an abnormal sampling timing warning is issued to the human-machine interface. Simultaneously, the corresponding sampling vehicle license plate number Y67 is sent as a prohibited vehicle license plate number to the access control system. The access control system identifies the cement truck's license plate number as Y67, which is a prohibited license plate number, and therefore prohibits the cement truck from entering the premises. The monitoring center viewed the warning information and corresponding risk warnings of abnormal sampling timing through the human-computer interaction terminal: "theft during transportation", "untimely sampling" and "traffic congestion". After supervision and investigation, it was found that the cement tanker truck with license plate number Y67 stole the transported concrete and mixed it with impurities during transportation, which increased the actual transportation time.
