Problems solved by technology
[0003] At present, the stress state inside the asphalt pavement is mainly monitored by embedding stress-strain gauges inside the asphalt pavement. However, such stress-strain gauges are bulky and difficult to install and easily damaged. In addition, due to the long-term extrusion of vehicles, the buried stress-strain gauges on the pavement The following strain gauges are prone to damage, so the accuracy and transmission of signals are not reliable

Abstract
The invention discloses a road surface pressure detection device. The road surface pressure detection device is arranged inside a road surface to be detected and comprises a shell, a circuit board is fixedly arranged at the bottom of the shell, a miniature pressure sensor, a control module and a wireless communication module are arranged on the circuit board, and the miniature pressure sensor is used for detecting a pressure signal acting on the miniature pressure sensor; the control module is electrically connected with the miniature pressure sensor and the wireless communication module and is used for converting a detected pressure signal into a wireless communication signal; and the wireless communication module is used for sending the wireless communication signal. The road surface pressure detection device is small in size, high in bearing capacity, capable of bearing long-time rolling compaction and not prone to damage, the road surface pressure detection device can be installed in the to-be-detected road surface for a long time, and the pressure condition borne by the road surface is detected in real time.
Description
technical field [0001] The present disclosure relates to the technical field of civil engineering road monitoring, in particular to a road surface pressure detection device. Background technique [0002] Asphalt pavement is the most widely used type of pavement structure. Under the repeated action of road vehicle loads, stress damage will occur inside the asphalt pavement material and accumulate continuously, resulting in damage to the asphalt pavement material, resulting in the destruction of the asphalt pavement. The current condition monitoring of asphalt pavement is often carried out by passing large vehicles on the road surface. The monitoring frequency is low, and it is difficult to perceive the changes of the pavement condition in real time. Therefore, only the diseases that have occurred can be monitored, but the process of the disease occurrence cannot be monitored. Therefore, accurate monitoring of the stress state inside the asphalt pavement can better study the m...
