With the rapid development of cities, people are putting forward increasingly higher requirements for driving comfort. At present, as various types of pipeline networks are increasingly installed under municipal roads, there are various types of inspection wells, such as water supply, rainwater, sewage, weak electricity and electric power distributed on municipal roads. The frequent vehicle loading causes the manhole covers of the inspection wells to subside and the pavements around to be broken. They have become the typical defects of inspection wells on urban roads, leading to poor driving comfort, vehicle congestion, poor cityscape, and even traffic accidents in severe cases. The municipal management department has invested a lot of manpower, material and financial resources for the defect detection and maintenance of inspection wells on municipal roads. However, the defects of inspection wells are prone to occur, and are often not detected and repaired in time due to the limitation by personnel, climate, traffic conditions and other objective factors. The municipal management department has always been plagued with post-remediation and passive rush repair despite large investment. To solve this problem, it is necessary to monitor and identify the operation conditions of the inspection wells on municipal roads and the surrounding pavements in time.
In order to solve the above problems described in the background, the utility model provides an intelligent monitoring and alarm device for subsidence of an inspection well on a municipal road and breakage of a surrounding pavement. The utility model can discover the defects of the inspection well on the road in time to ensure the safe and comfortable operation of the municipal road infrastructure.

The front-end system includes a power supply, a thin strain wire, an MCU and a GPS chip. The power supply, the thin strain wire and the GPS chip are respectively connected to the MCU. The thin strain wire is connected to the power supply to form a current loop, and the power supply continuously powers the loop. The MCU is connected to the back-end system via an NB-IoT to implement data interaction. The utility model realizes the timely monitoring, discovery and alarm of the current major defects of the inspection wells on municipal roads, namely the subsidence of the inspection wells and the breakage around the wells. The utility model is convenient for the municipal management department to realize the intelligent management, operation and maintenance of urban roads, timely discover the defects of the inspection wells on the road, and actively organize emergency repairs. Therefore, the utility model ensures the safe and comfortable operation of the municipal road infrastructure. In the utility model, the thin strain wire is arranged in a serpentine shape, and closely and symmetrically arranged in the surface course of the pavement around the manhole cover of the inspection well, for monitoring the quality of the manhole cover of the inspection well and the surrounding pavement. When the manhole cover of the inspection well is subsided or the pavement around the well is cracked or broken, the resistance of a strain resistance wire in the thin strain wire is suddenly changed or the strain resistance wire is broken. Accordingly, the current in the current loop formed by the thin strain wire and the power supply is abruptly changed or no current flows through the current loop. In this way, the defects are discovered in time based on the abnormal current signal, and a timely alarm is given. The utility model uses the NB-IoT to intelligently monitor the subsidence of inspection wells on urban roads and the damage of the surrounding pavement, which realizes the remote centralized management of the inspection wells on the municipal road in an urban area. The utility model reports the received alarm message to the maintenance personnel in time, so that they can repair the inspection wells on the road.

Example
As shown in FIGs. 1 to 3, the utility model provides an intelligent monitoring and alarm device for subsidence of an inspection well on a municipal road and breakage of a surrounding pavement based on a narrow band-Internet of things (NB-IoT), including a front-end system 1, an NB-IoT base station 2, an NB-IoT packet core network 3, a back-end system 4, a manhole cover 5, a well base structure 6 and a surface course 7 of a pavement. The front-end system 1 implements data interaction with the back-end system 4 through the NB-IoT base station 2 and the NB-IoT packet core network 3. The manhole cover 5 is located above the well base structure 6. The surface course 7 of the pavement is connected to the well base structure 6 and the manhole cover 5.
The front-end system 1 includes a microcontroller unit (MCU) 11, a power supply 12, a thin strain wire 13, a global positioning system (GPS) chip 14 and an NB-IoT 15. The MCU 11 is located in the well base structure 6. The GPS chip 14 is used to locate the position of the inspection well. The power supply 12 is located on an inner side wall of the well base structure 6 to power the entire system. The thin strain wire 13 is located in the surface course 7 of the pavement and arranged in a serpentine shape to form a current loop with the power supply 12. The NB-IoT 15 is located on the inner side wall of the well base structure 6 to implement wireless communication for information transmission.
The back-end system 4 includes an NB-IoT platform 41, a mobile terminal 42, a personal computer (PC) terminal 43 and an operation and management server 44. The NB-IoT platform 41 is connected to the mobile terminal 42, the PC terminal 43 and the operation and management server 44. The operation and management server 44 is connected to a data storage unit 45 and an alarm module 46, for storing, maintaining and determining the information of the inspection well and sending out alarm information.
The thin strain wire 13 is connected to the power supply 12 to form a current loop, and the power supply 12 continuously powers the loop. The thin strain wire 13 is arranged in a serpentine shape and pre-buried in the surface course 7 of the surrounding pavement adjacent to the manhole cover 5, for monitoring the quality of the manhole cover 5 and the surrounding pavement. When the inspection well is subsided or the pavement around the well is cracked or broken, the resistance of a strain resistance wire in the thin strain wire 13 is suddenly changed or the strain resistance wire is broken. Accordingly, the current in the current loop formed by the thin strain wire 13 and the power supply 12 is abruptly changed or no current flows through the current loop. The MCU 11 receives a signal of abrupt current change or open-circuit zero current in the current loop, and periodically wirelessly transmits the signal via the NB-IoT 15 to the alarm module 46 in the back-end system 4. The alarm module 46 determines that the manhole cover 5 is subsided or the surface course 7 of the surrounding pavement is damaged according to the received signal, and the GPS chip 14 locates the position of the manhole cover 5. The data transmitted from the front-end system 1 to the back-end system 4 is viewed through the mobile terminal 42 or the PC terminal 43. The data storage unit 45 stores the received information. The alarm module 46 determines and gives an early warning on the transmitted abnormal data, and counts the number of breakages around the inspection well. Maintenance personnel promptly repairs the defective inspection well according to the alarm information and GPS positioning signal.
The above described are merely preferred examples of the utility model, and are not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should fall within the protection scope of the utility model.
