[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Reference Figure 1-3A road compaction device with intelligent monitoring includes a vehicle body 1 and a vibrating wheel 8. A mounting frame 9 is provided on the front side of the vehicle body 1. The vibrating wheel 8 is rotatably connected to the mounting frame 9. The vibrating wheel 8 compacts the road surface using its own gravity and vibration. An excitation mechanism is provided inside the vibrating wheel 8. The excitation mechanism includes an eccentric block (or eccentric shaft), a vibrating bearing, a bearing seat, and a coupling. The eccentric block is driven to rotate by a hydraulic motor or mechanical transmission. When the eccentric block rotates, it generates centrifugal force, which forms an excitation force. Hydraulic drive, which uses a hydraulic motor to drive the vibratory shaft, can achieve stepless frequency and amplitude adjustment, resulting in better compaction effect; mechanical drive, which uses an engine to directly drive the vibratory shaft, has a compact structure, but lower frequency and amplitude adjustment flexibility. The vehicle body 1 is equipped with an industrial control computer and a wireless communication antenna 3. The industrial control computer is connected to the control terminal through the wireless communication antenna 3. The control terminal includes a monitoring center server and a database, which facilitates the owner, construction party, supervisor and operator to obtain timely and accurate construction process information, realize real-time and fully digital management of the road construction process. The management personnel can view the equipment status, operation progress and compaction quality in real time, and at the same time, the operator can remotely control the road roller. The industrial control computer is connected to a driving information acquisition system, a construction information acquisition system, and a road rolling construction execution system; The driving information acquisition system includes a high-precision positioning module, an environmental perception module, and a vehicle speed sensor. The high-precision positioning module includes a satellite positioning device and a GPS base station to accurately plan the operation path and ensure that the rolling trajectory error is controlled within 2-3 cm. The environmental perception module includes a panoramic camera 2, an ultrasonic radar 4, and a millimeter-wave radar 10. The panoramic camera 2 is a 360-degree panoramic camera used to capture 360-degree environmental image information around the vehicle body 1. The millimeter-wave radar is used for medium- and long-range object detection to realize adaptive cruise control and collision warning. The ultrasonic radar 4 has a detection range of up to 4 meters, which meets the obstacle avoidance requirements of the road roller when traveling at low speed (5 km / h). The vehicle speed sensor is used to detect the driving speed of the vehicle body 1. The construction information acquisition system includes a road surface recognition camera 7, a temperature sensor, a compaction sensor 6, and an angle sensor. The road surface recognition camera 7 is located below the mounting frame 9. As needed, road surface recognition cameras 7 can be installed in front of and behind the vibrating wheel 8 to record and recognize road surface images. Based on deep learning algorithms and combined with the environmental information of the vehicle body 1 collected by the driving information acquisition system, it can realize unmanned intelligent path planning and correction, or assist construction personnel in remotely controlling the driving and remotely completing the road surface compaction work. The compaction sensor 6 is installed at the rotating shaft of the vibratory roller 8 to measure the feedback force waveform of the compacted material in real time and calculate the degree of compaction. The vibratory roller 8 is the core working component of the road roller, and its vibration characteristics directly reflect the compaction effect. The vibratory roller 8 is in direct contact with the material being compacted (such as soil and asphalt), and its vibration characteristics will change with the change of material density. The compaction sensor 6 captures the dynamic response signal of the vibratory roller 8 and combines physical effects and signal processing technology to reflect the density or compaction state of the material being compacted in real time. A compaction detection device 5 is provided on one side of the mounting frame 9. The compaction detection device 5 includes a connecting seat, a swing arm, and a roller. The upper end of the swing arm is rotatably connected to the mounting frame 9 through the connecting seat. The swing arm is tilted, and the roller is rotatably set at the lower end of the swing arm. The tilted swing arm presses down to ensure that the roller is in contact with the road surface being compacted. The temperature sensors include an ambient temperature sensor and a compaction temperature sensor. The ambient temperature sensor is used to detect the environment of the construction site, which is convenient for planning the equipment working time and avoiding long-term operation that could lead to excessively high equipment temperature and damage. The compaction temperature sensor is set inside the roller. The roller is made of a material with good thermal conductivity, which is convenient for the compaction temperature sensor to detect the temperature of the compacted road surface and provide a basis for adjusting the compaction process. An angle sensor is set between the swing arm and the connecting seat. When the road surface is uneven, the vibrating wheel 8, the vehicle body 1, and the roller bounce up and down. The angle sensor detects the swing amplitude of the swing arm and determines the road surface flatness, which is convenient for construction personnel to plan and adjust the number of compaction passes. The road rolling construction execution system includes a traveling mechanism, a steering mechanism, a braking mechanism, and a vibration excitation mechanism. The traveling mechanism, steering mechanism, and braking mechanism are used to enable the vehicle body 1 to drive, steer, and brake normally. The vibration excitation mechanism changes the rotation speed of the eccentric block through a hydraulic motor or mechanical transmission, adjusts the vibration frequency, and adjusts the rolling effect.

[0015] In this embodiment, construction personnel determine the construction area and formulate a construction plan based on the construction plan. They determine the roller's compaction trajectory, travel speed, and compaction intensity. The control terminal sends construction instructions to the industrial control computer, and the roller starts working. The road surface is compacted according to the construction plan. During this process, the high-precision positioning module, environmental perception module, and vehicle speed sensor assist the roller in achieving unmanned operation. This facilitates remote management and control adjustment by the operator, eliminating the need to drive the equipment on-site. One operator can simultaneously monitor and operate multiple rollers, effectively improving construction efficiency. The roller can operate continuously, in all weather conditions, shorten the construction period, reduce safety risks and costs, and adapt to construction in hazardous environments. The compaction system, consisting of a pavement recognition camera (7), temperature sensor, compaction sensor (6), and angle sensor, monitors compaction construction status parameters. This assists the industrial control computer in controlling the road compaction execution system, enabling intelligent completion of pavement compaction work. It achieves real-time, continuous, and visual guidance and management of data such as compaction trajectory, compaction strength, and compaction temperature during pavement construction. It provides timely and accurate construction process information to the owner, construction party, supervisor, and machine operator, realizing real-time and fully digital management of the pavement construction process.
