The sensor component 5 is provided with multiple groups, which are respectively arranged at the bottom of the corresponding storage box 1, detect the corresponding part of the concrete structure, and send the detection value to the first communication module 6. The first communication module 6 can perform digital-to-analog signal conversion, and it is connected to the central control module for communication, and transmits the collected detection value to the central control module. When the monitoring and maintenance system of the utility model is in operation, the central control module determines the presence of cracks or corrosion at the corresponding part of the concrete structure according to the detection value of the sensor component 5, controls the corresponding cover opening component 4 in the storage box 1 to retract, drives the sealing cover 2 inward to open the discharge port, and the repair liquid flows out from the discharge port to repair the damaged part.

Further, in order to prevent the sealing cover 2 from being too firmly bonded to the concrete and unable to be opened, a smooth surface layer is provided on the outside of the sealing cover 2, and a release agent is sprayed on the smooth surface layer. After the concrete is solidified, the cover opening component 4 performs a contraction action, which can easily drive the sealing cover 2 to separate from the concrete surface. Preferably, in order to facilitate the later replenishment of the repair liquid, the top of the storage box 1 is also provided with a filling cover, and the repair liquid can be injected into the storage box 1 by opening the filling cover.

The sensor assembly 5 is arranged at the bottom of the storage box 1, which is placed in the concrete structure when pouring concrete, and the sensor data line is left out to connect with the first communication module. The damage information is detected by the sensor assembly 5 correspondingly arranged at the bottom of the storage box 1. The central control module can accurately control the repair liquid at the corresponding storage box 1 to automatically repair the damaged part.

[0033] Furthermore, the monitoring and maintenance system of the embodiment of the utility model also includes a second communication module and a remote control unit; the second communication module is communicatively connected to the central control module, converts the received central control module signal into a wireless signal and sends it to the remote control unit, so that engineering personnel can monitor the status of the concrete structure in real time through the remote control unit and perform remote operations.

[0034] The monitoring and maintenance system of the utility model can monitor the status of the concrete structure in real time, discover problems in time and take measures to avoid accidents through the cooperation between the sensor component 5, the first communication module 6, the second communication module, the human-computer interaction unit, the remote control unit and the central control module; it solves the problem of low efficiency of traditional manual inspection and monitoring, improves the failure resistance of the concrete structure in the monitoring process and maintains the stability of the concrete structure, and has strong practicality.
