Such as a level monitoring sensor 100 that monitors the level of liquid within the manhole, a harmful gas sensor 105 that monitors harmful gases, and a manhole cover status sensor 110 that monitors the status of the manhole cover (e.g., open and closed). Those skilled in the art will appreciate that other types of sensors may also be included.
The monitoring data concentrator device 20 is configured to collect the monitoring data. For example, the position data of the liquid level in the inspection well from the liquid level monitoring sensor 100, the harmful gas data from the harmful gas sensor 105, and the well lid state data from the well lid state sensor 110 are collected.
In one embodiment, as shown in fig. 2, the monitoring data concentration device 20 includes a bluetooth module 200, a master control module 205, a wireless communication module 210, a power module 215, and a housing 220.

For example, the manhole cover state sensor 110, the liquid level monitoring sensor 100, and the harmful gas sensor 105 complete bluetooth pairing with the monitoring data concentration device 20 through the bluetooth module 200, and are in a dormant state. When the device reaches a preset uploading period (for example, 1 hour), the monitoring data concentration device is awakened and is in Bluetooth connection with each sensor; each sensor transmits various monitoring data to the monitoring data centralized equipment through the Bluetooth module. In consideration of actual conditions, the device does not need to collect data every moment, and for this reason, the preset uploading period can be set, and when the period is not reached, the Bluetooth is in a dormant state. When reaching this cycle, just awaken up, begin work to can let equipment more power saving, this just very useful under the inconvenient condition of often taking out the charging of this equipment setting in the inspection shaft.
In a preferred example, the bluetooth module employs a BLE5.0 bluetooth module of SKYLAB.

In one example, the wireless communication module 210 communicates with the main control module 205 through a Universal Asynchronous Receiver Transmitter (UART) to obtain the monitoring data.
In one example, the wireless communication module 210 employs an NB-IoT network to enable communication with the monitoring server 30. In one preferred example, the wireless communication module employs the currently commonly used remote NB-IoT communication module LTE BC 28.
In one example, the wireless communication module encrypts the monitoring data and transmits the encrypted monitoring data to the monitoring server 30.
The power supply module 215 supplies power to the monitoring data concentration device 20 to ensure normal operation of the device. For example, the power supply module provides a 7.2V power supply for the device, and supports the operation of the device.
In a preferred example, the power supply module is powered by an external solar panel. Other power supply means may be used, and the present invention is not limited thereto.
The bluetooth module 200, the main control module 205, the wireless communication module 210 and the power supply module 215 are all arranged in the housing 220.
Because the equipment is installed in the manhole, for corrosion protection, in one example, the housing 220 is coated with a corrosion-resistant molding powder to protect the housing from corrosion.
For waterproofing, the housing may be filled with glue, such as 9001 glue, and sealed, with a protection rating of IP 68.
Aiming at the explosion-proof requirement of the gas lock well, the intrinsic safety level design is carried out, and the explosion-proof requirement is ensured.
As shown in fig. 3, the monitoring method according to an embodiment of the present invention is implemented by a system 1, and includes the steps of:
the bluetooth module 200 and the various monitoring sensors 10 complete bluetooth pairing and are in a dormant state;
when a preset uploading period is reached, the main control module 205 wakes up the bluetooth module to connect with various monitoring sensors to transmit the various monitoring data;
