[0039] It is to be noted that the terms "one" and "a plurality" used in the present application are illustrative and not restrictive, and those skilled in the art should understand that "one" or "a plurality" should be understood as "one or more" unless otherwise explicitly stated in the context.

[0040] The names of the messages or information exchanged between the plurality of apparatuses in the embodiments of the present application are only for illustrative purposes, and are not intended to limit the scope of the messages or information.

[0041] As shown in Figure 1 The road compaction monitoring system provided in the embodiments of the present application includes a sensor module 10, a data acquisition and transmission module 20, a GPS positioning module 30, a data processing module 40, a display and early warning module 50, and a wireless communication module 60.

[0042] As shown in Figure 2 The sensor module 10 is installed on the vibrating wheel of the road roller, the display and early warning module 50 is installed on the instrument desk of the road roller, the data acquisition and transmission module 20, the wireless communication module 60, the data processing module 40, and the GPS positioning module 30 are integrated in the same housing 70, and the housing 70 is installed in the cab of the road roller. According to the interface types (such as serial ports, USB interfaces, etc.) of the various modules, the various modules are placed at appropriate positions on the circuit board to ensure that stable physical connections can be established between the various modules to achieve normal transmission of electrical signals.

[0043] It should be noted that the power requirements of each module are different, and different modules require different voltages and currents for power supply. For example, the wireless communication module 60 may require a 3.3V power supply and an operating current of several hundred milliamperes, while the data processing module 40 may require a 5V power supply input, etc. By integrating the data acquisition and transmission module 20, the wireless communication module 60, the data processing module 40, and the GPS positioning module 30 in the same housing 70, using a power management chip or a power supply circuit, the appropriate power supply is uniformly distributed and converted to each module, ensuring that they can work stably, while also doing a good job of filtering and other processing of the power supply to reduce the interference of power supply noise on the module operation.

[0044] In this embodiment, the sensor module 10 is used to collect the force exerted by the vibratory roller on the road structure layer and the acceleration of the vibratory roller, and to send an electrical signal to the data acquisition and transmission module.

[0045] Specifically, the sensor module 10 includes a pressure sensor and an acceleration sensor.

[0046] The pressure sensor and the acceleration sensor are both mounted on the axle of the vibratory roller. The output terminals of the pressure sensor and the acceleration sensor are both connected to the input terminals of the data acquisition and transmission module.

[0047] The pressure sensor is mounted on the axle of the vibratory roller. It should be noted that the pressure sensor is a strain gauge pressure sensor. When the steel wheel of the vibratory roller exerts pressure on the road structure layer, the reaction force of the road structure layer causes the strain gauge of the strain gauge pressure sensor to deform, and the resistance of the strain gauge changes. The amount of change is converted into an electrical signal by a circuit, and the strength of the electrical signal is in a specific functional relationship with the size of the pressure, which is closely related to the degree of compaction. Therefore, the degree of compaction is indirectly reflected through the electrical signal.

[0048] The acceleration sensor is mounted on the axle of the vibratory roller. It should be noted that the acceleration sensor is a MEMS (Micro-Electro-Mechanical Systems) acceleration sensor. During vibratory compaction work of the vibratory roller, the MEMS acceleration sensor can sensitively capture the acceleration changes of the vibratory roller. Due to the different degrees of compaction of the material, the vibration characteristics of the vibratory roller change, and the acceleration also changes accordingly. The sensor converts this change into an electrical signal output.

[0049] In this embodiment, the data acquisition and transmission module 20 is used to sequentially amplify, filter, and analog-to-digital convert the received electrical signal to obtain a converted signal, and to send the converted signal to the data processing module.

[0050] Specifically, the data acquisition and transmission module includes a data acquisition card and a wireless transmission unit.

[0051] The input end of the data acquisition card is connected with the output end of the pressure sensor and the acceleration sensor; the output end of the data acquisition card is connected with the input unit of the wireless transmission unit; and the output end of the wireless transmission unit is connected with the input end of the data processing module.

[0052] The data acquisition card is connected with the pressure sensor and the acceleration sensor respectively, and is used for sequentially performing amplification processing, filtering processing and analog-digital conversion processing on the weak electric signal output by the received sensor. After the analog-digital conversion processing, the analog signal is converted into a digital signal, which is more convenient for processing and transmission. The data acquisition card sends the converted signal (digital signal) obtained through the analog-digital conversion processing to the wireless transmission unit. In this embodiment, a specific data acquisition card is provided, which is an XM7016 type data acquisition card or a PCIe8504 / 8514 type synchronous data acquisition card.

[0053] The wireless transmission unit is used for sending the received converted signal to the data processing module. The wireless transmission unit is connected with the data acquisition card and the data processing module, receives the converted signal sent by the data acquisition card, and sends the received converted signal to the data processing module.

[0054] In this embodiment, the wireless transmission unit adopts any one of WIFI signal transmission, Bluetooth signal transmission and ZigBee signal transmission. The wireless communication mode does not need a physical line, and improves the flexibility of installation of the data acquisition unit. For example, in a large road construction site, the data can be transmitted to a remote control system in real time through the WIFI signal transmission mode. That is, the current compaction condition of the road structure layer can be obtained through a remote mode, the remote compaction monitoring is realized, and the engineering management personnel can grasp the compaction degree data at any time. Specifically, the data processing module is arranged in the cab of the road roller, and the Bluetooth signal transmission mode is adopted for the transmission of the electric signal. The Bluetooth signal transmission mode can reduce the hardware cost of the equipment and the power consumption of the wireless transmission unit, and is also easy to implement. Specifically, the wireless transmission unit in this embodiment is a Bluetooth module unit based on an nRF52832 chip or a Bluetooth module unit based on a TD5165A chip.

[0055] In this embodiment, the GPS positioning module 30 is configured to receive satellite signals and determine the geographical position signal of the road roller based on the satellite signals, and send the geographical position signal to the data processing module. The GPS positioning module is installed on the road roller and determines the geographical position information of the road roller by receiving satellite signals, including longitude, latitude and altitude, etc. The position data of the road roller is associated with the compaction degree data. In this way, a compaction degree distribution map of the entire construction area can be drawn to intuitively show the compaction situation at different positions. For example, in road construction, it can be clearly seen whether the compaction degree of different road sections and different lanes is uniform, and whether there are areas of insufficient compaction or excessive compaction, facilitating quality control and problem troubleshooting by construction personnel. At the same time, in the subsequent engineering acceptance and maintenance process, the compaction degree data of a specific area can also be quickly located according to the position information, providing a strong basis for engineering quality evaluation and maintenance decision-making. Specifically, in this embodiment, the GPS positioning module adopts a GPS module unit based on AT6558R chip or a GPS module unit based on u-blox chip.

[0056] In this embodiment, the data processing module 40 is configured to receive the conversion signal and the geographical position signal, convert the conversion signal to obtain the compaction degree data, and convert the geographical position signal to obtain the geographical position data; and send the compaction degree data and the geographical position data to the display and warning module and the wireless communication module.

[0057] In this embodiment, the data processing module receives the conversion signal and the geographical position signal, and converts the conversion signal to obtain the compaction degree data according to the pre-stored compaction degree-sensor mathematical model in the data processing module (the compaction degree-sensor mathematical model is a curve representing the change of compaction degree with the change of the electrical signal output by the sensor). It can be understood that the conversion signal received by the data processing module in this embodiment includes the first conversion signal obtained by processing the electrical signal output by the pressure sensor through the data acquisition and transmission module, and the second conversion signal obtained by processing the electrical signal output by the acceleration sensor through the data acquisition and transmission module. The data processing module converts the first conversion signal to obtain the first compaction degree data, and converts the second conversion signal to obtain the second compaction degree data. Exemplarily, when the first compaction degree data is less than or equal to the second compaction degree data, the first compaction degree data is taken as the output data, and the first compaction degree data is sent to the display and warning module and the wireless communication module. Conversely, if the first compaction degree data is greater than the second compaction degree data, the second compaction degree data is taken as the output data, and the second compaction degree data is sent to the display and warning module and the wireless communication module.

[0058] The data processing module in this embodiment calculates its three-dimensional coordinates on the earth, i.e., longitude, latitude and height, based on the received geographic position signals, by using the principle of triangulation or multilateration, thereby obtaining accurate geographic position data. Specifically, the data processing module is a single-chip microcomputer controller, a digital signal processor or a programmable logic device.

[0059] In this embodiment, a display and warning module 50 is configured to visually process the received compaction degree data and geographic position data, display the visually processed compaction degree data and geographic position data, and determine whether the compaction degree data is lower than a set standard value and issue an alarm signal through an audible and light alarm if the compaction degree data is lower than the set standard value.

[0060] Specifically, the display and warning module includes a display screen and a warning unit.

[0061] The input end of the display screen is connected to the output end of the data processing module. The input end of the warning unit is connected to the output end of the data processing module.

[0062] The display screen is configured to receive the compaction degree data and the geographic position data and visually process the compaction degree data and the geographic position data, and display the visually processed compaction degree data and the geographic position data. The warning unit is configured to determine whether the compaction degree data is lower than a set standard value and issue an alarm signal through an audible and light alarm if the compaction degree data is lower than the set standard value.

[0063] It should be noted that the display screen can be a driving display screen of the road roller cab or a large screen of a remote monitoring center. The compaction degree data is displayed intuitively. In this embodiment, the display and warning module is arranged in the cab of the road roller, and the display screen is a driving display screen of the road roller cab. The compaction degree data in the construction process is displayed in real time and online through the driving display screen, and the position of the current road roller is determined through the display screen. In addition, the operator of the road roller can see in real time whether the compaction degree of the current road roller position meets the standard through the driving display screen, so that the operator can adjust the operating parameters of the road roller according to the operating data. The frequency of subsequent manual detection of the compaction degree of the roadbed is reduced, and the construction efficiency is improved. The problem of non-standard compaction degree of the road structure layer when detecting the compaction degree of the road structure layer is avoided, and the construction quality is ensured.

[0064] The warning unit is configured to determine whether the compaction degree data is lower than a set standard value and issue an alarm signal through an audible and light alarm if the compaction degree data is lower than the set standard value.

[0065] In this embodiment, when the compaction degree data is lower than the set standard value, the audible and light alarm is triggered to issue an alarm signal. In the compaction of the road structure layer, if the compaction degree does not meet the design requirement of 95%, the audible and light alarm immediately issues an alarm to remind the operator of the road roller to perform a supplement compaction operation. Specifically, the warning unit is a GR-150 / G type integrated audible and light alarm.

[0066] In this embodiment, the wireless communication module 60 is used to receive the compaction degree data and the geographic position data, and transmit the compaction degree data and the geographic position data to the remote terminal.

[0067] The wireless communication module is installed on the road roller and connected with the data processing module, and transmits the compaction degree data and the geographic position data received by the data processing module to the remote terminal. Specifically, the wireless communication module is a 4G communication module unit or a 5G communication module unit. Taking the 4G communication module unit as an example, the data is packaged and sent to the designated remote terminal by using the mobile communication network. The remote terminal receives the data from the road roller through the network interface and performs subsequent processing and analysis. This wireless transmission method breaks through the limitation of traditional wired connection, so that the road roller can move freely during construction and is not restricted by the length of the cable and the position of the wiring, greatly improving the flexibility and efficiency of the construction. At the same time, it is also convenient to centrally manage and monitor the data of multiple road rollers in a large construction area, for example, in a large road engineering or airport runway construction project, the compaction conditions of multiple road rollers can be monitored and dispatched in real time.

[0068] On the basis of the above-mentioned road compaction monitoring system, further comprising a data storage module.

[0069] The input end of the data storage module is connected with the output end of the data processing module.

[0070] The data processing module is further used to transmit the compaction degree data and the geographic position data to the data storage module. The data storage module is used to receive and store the compaction degree data and the geographic position data.

[0071] The data storage unit stores the compaction degree data for subsequent query, statistical analysis and quality traceability. The data storage unit is a hard disk, which can save a large amount of data in a long construction process. It should be noted that the storage and analysis of a large amount of compaction degree data provide data support for engineering quality evaluation, subsequent maintenance, and facilitate the informatization and intelligent development of engineering management.

[0072] The embodiment provides a road compaction monitoring system, compaction degree data is collected, transmitted, processed and displayed through a sensor module, a data acquisition and transmission module, a data processing module and a display and early warning module, the compaction condition of a road structure layer can be determined in real time, real-time and effective construction is realized, position data of a road roller is determined through a GPS positioning module, the position data and the compaction degree data can be associated, and the compaction condition at different positions can be intuitively displayed. The position data and the compaction degree data are sent to a remote terminal through a wireless communication module, so that the road roller can be freely moved in the construction process, is not restricted by the length of a cable and the position of wiring, and the flexibility and efficiency of construction are greatly improved. The display and early warning module is used for judging and early warning the compaction index of the compaction degree, the process control in the compaction process and the coherence of a construction procedure are improved, cost is saved, and efficiency is improved.

[0073] Although the utility model discloses as above, the protection scope of the utility model is not only limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
