Smart manhole cover solution
The Current Situation of Traditional Manhole Covers
A large number of inspection wells are produced in the construction of electricity, communication (radio and television, telecommunications, mobile, Unicom), municipal administration, gas, sewage and rainwater, water plants and fire protection. However, there is a lack of effective real-time monitoring and management means (mainly manual inspection). Manhole cover losses frequently occur in various places, and the road surface becomes a trap, threatening the safety of pedestrians and vehicles! The underground pipe network resources are scarce, and the problem of unauthorized crossing is serious.
Problems faced by management departments: How to effectively supervise?
The manhole cover is lost but no one knows.
When the manhole cover is lost, the person responsible cannot be found.
Whose responsibility is it when a certain one is lost?
How to solve the above confusions through technological means?
Urban rainwater manhole covers, sewage manhole covers, communication cable manhole covers, etc. In addition to being prone to loss, these manhole covers have different materials and unequal qualities. Many manhole covers are exposed to sun and rain and crushed by vehicles, and can easily become "road black holes", posing safety hazards to passing vehicles and pedestrians.
How can management departments effectively supervise when facing problems?
How to control the source of inferior manhole covers?
Damaged manhole covers cannot be replaced in time.
It takes a long period to hold those responsible for accidents.
How to solve the above confusions through technological means?
System Architecture
Working Principle
The intelligent manhole cover management system includes a cloud management platform, an APP, emergency electronic keys, and intelligent manhole covers. Personnel, intelligent manhole covers, and electronic key ledgers are entered in the management platform; the permissions of personnel and electronic keys can be set through the platform. Specified personnel can open which intelligent manhole covers within what time period. Operators log in to the mobile phone APP to view the assigned tasks (that is, the permissions they have). Operators can unlock directly through the APP or via Bluetooth through the mobile phone APP, and can view the status of the intelligent manhole cover. The monitoring data of the external cover and the environment information inside the well of the intelligent manhole cover is pushed to the platform and the mobile phone APP in real time.
System Architecture
The concept of the IoT for smart manhole covers
According to the distribution characteristics of urban manhole covers, fully combined with the actual application scenarios and adapted to local conditions, through the current mainstream wireless/wired cloud sensor network networking methods such as 4G/NB/485/DO, the deployment of the intelligent real-time cloud monitoring and control Internet of Things system for "urban manhole covers" can be quickly realized. While fully ensuring the safety of various manhole covers, it greatly shortens the construction time of the real-time monitoring system and reduces the implementation cost of the system.
Functions such as monitoring, real-time alarming, automatic inspection, and timely handling of the manhole cover status (opening, displacement, inclination) and the underground status (temperature, liquid level, concentration of toxic gases) are achieved. At the same time, considering the safety and importance of manhole cover opening, intelligent anti-theft locks can be installed on the manhole covers. The local and remote secondary authentication opening methods are used to ensure the safety of the manhole covers. The smart manhole cover system further improves the informatization and intelligentization level of municipal management and lays the foundation for industry applications in smart cities.

Example of application scenarios
-
1、Engineer Zhang received a notice that an accident occurred with the manhole cover in Area A and needs to go to the site for handling.
-
2、The system administrator sends the unlocking authorization to Zhang through the system platform.
-
4、Administrator Li queries Zhang's maintenance record through the system platform to confirm the completion of Zhang's work.
-
3、Zhang arrives at the accident site and uses the mobile phone APP to connect with the lock via Bluetooth. The manhole cover lock is opened. Zhang carries out the maintenance work. After the maintenance is completed, the manhole cover lock is closed and the data of opening and closing the lock is uploaded in real time.

Security
The bearing capacity of the intelligent manhole cover is > 34KN; Digital coding is adopted to prevent technical opening; It can monitor the opening of the outer cover and upload the status of the outer cover and the environment inside the well in real time; All kinds of alarm information are pushed in real time
Intelligentization
The lock can be opened in multiple ways. It is clear who opens which manhole cover at what time, and the records can be queried in real time on the backstage for intelligent and traceable management. The status information and alarm information of the manhole cover and the inside of the well are pushed in real time to facilitate the timely and effective management by the management personnel. This makes the management simple, precise, effective and intelligent.
GPS navigation
The equipment is scattered in various locations. In the process of operation and maintenance inspection and equipment emergency repair, a lot of time and energy are required to find the stations. The intelligent manhole cover system has a visual navigation function, which can enable the staff to arrive at the designated site at the first time, greatly saving the time of finding the stations and improving work efficiency.
Step-by-step authorization and real-time monitoring
Traditional management requires the submission of work tickets for step-by-step approval, which wastes time. Reports cannot determine their accuracy and timeliness. The intelligent access control system enables step-by-step authorization for staff to open and lock, and relevant logs can be viewed in real time. After the implementation, centralized management, step-by-step authorization, and real-time viewing of relevant records are achieved.
