Manhole cover sensors
The Best Sensing Solutions—Directly from the street
Description
Manhole Protector: From Manhole lock to Manhole cover open detector
Manholes leading to underground supply systems are essential for their maintenance, for example, it concerns telecommunication networks, water supply networks, gas supply networks and electricity networks, and so on. Although it is very crucial to a city’s operations, the manhole can be one of the least protected and most vulnerable assets.
Nowadays manhole cover failure such as metal theft (for manhole cover or copper cable underneath it) is on the rise and generally becomes a society issue. An unauthorized opening of manhole is very dangerous, it can cause deadly fall-in accidents to people and also inflict a huge amount of damage to public property.
The conventional Manhole locks
To protect the manhole and prevent it from being opened by simply a manhole cover hook, conventionally, the use of the manhole cover locks has been implemented. One problem is that it is hard for the manhole O&M agency to manage so many manhole keys, sometimes the keys are lost and this increases the
difficulty. Another problem is that it may make the road surface uneven with the additional key structure on the manhole.
With the new technology developments, the need for a fully automated manhole monitoring system has become practical. Automated monitoring of manhole and manhole cover is part of the development of smart cities and Internet of Things (IoT) which are the targets for modern governments to control and monitor the
assets in cities.
Manhole cover open detector
With 6=’s Manhole Cover Open Detector, you can deploy real-time monitoring and protection against metal theft, vandalism, and unauthorized access of manholes.
The product utilizes a range of commercially available, off- theshelf sensors to detect and prevent manhole related incidents. Signals are transmitted from the sensor device to a cloud platform via LPWAN (Low Power Wide Area Network) technologies, such as GPRS, NB-IoT, etc. The sensors in combination with the cloud-based dashboard will allow you to monitor and well plan the maintenance of manholes.
Key Features
• Detect open/closed status of a manhole cover
• Easy to install, wireless communication and free maintenance
• Cloud based platform with GIS (Geographic information system) dashboard
• Automatic alarm and message notification support
Benefits
• Monitor, report, predict and optimize your manholes
• Pick up on unauthorized activities and well plan maintenance schedules
• 24/7 monitoring with multiple status messages updated per day and instant alarm notification
• Total flexibility and reliability, can be deployed in urban or rural environments
