Application of NB-IoT in manhole cover monitoring

Application of NB-IoT in manhole cover monitoring

Our city is undergoing rapid construction. The number of underground projects for municipal public infrastructure is increasing. The increase of manhole covers is inevitable. The role of manhole covers is huge. If information on the status of manhole covers cannot be obtained in time, it may cause extreme damage to people’s lives and property. Big loss.

At present, most cities are managed by manual inspection, but the number of manhole covers is huge, and the efficiency of manual inspection is limited. It is often impossible to obtain timely and accurate information about the state of manhole covers, which leads to various safety hazards.

Is the manhole cover stolen? Is the manhole cover destroyed?

The theft or damage of the manhole cover will not only directly cause the loss of public property, but also may cause irreparable personal injury and economic loss to nearby pedestrians and vehicles.

How to eliminate these hidden safety hazards has become a top priority. Using NB-IoT to locate and monitor the manhole cover can grasp the status information of the manhole cover in time, and use the NB-IoT network to send an alarm to the server to notify the manager when the manhole cover moves or is damaged, so as to maximize The degree of avoidance of injury and loss.

Advantages of using NB-IoT technology for manhole cover monitoring

Manual inspections are no longer required, and all data is automatically transmitted to the platform, saving a lot of human resources.

NB-IoT can accommodate 10 times the user capacity of communication base stations than GPRS, which can meet the huge number of manhole covers.

NB-IoT has ultra-low power consumption, normal communication and standby current are mA and uA levels, module standby time can be as long as ten years, which greatly simplifies the maintenance of manhole cover monitoring in the later period.

NB-IoT has a stronger and wider signal that can cover indoors and basements, truly realizing comprehensive coverage in manhole cover monitoring.

NB-IoT technology breaks through the bottleneck of GPRS technology and is bound to shine in the wireless communication industry in the future.
