The ISW system is a new product developed by my company. The system uses advanced sensor technology, wireless communication technology and geo-information technology for networking, so as to achieve active sensory and real-time monitoring of the well cover state, and in the event of irregularities such as illegal opening and water filling, the monitoring terminal immediately sends alarm messages to the management centre via the NB-IOT network, notifys the maintenance staff of their first-time disposal, thereby increasing the efficiency of the operation, removing hazards at an early stage and maximizing the safety of public facilities and pedestrians and vehicles.
Device Functions
- Real-time monitoring of alarms
The response to changes in the condition of the well covers can include tilting of the covers, turning them over, extending the bathing alert, etc.
- Time reports.
Setable time-reporting functions, including wellhead tipping, battery power, signal strength, etc.
- Organisation
Equipment generation and maintenance logs (e.g., NB mode and emergency mode cover state monitoring, equipment coding, etc.).Where the device does not have a signal, the relevant information can be stored locally and automatically relayed after resumption of communication.
- Remote-painted defence
In the course of transport, installation or silo overhaul, well cover alarms can be removed through platforms or AP-controlled alarms to avoid constant alarm messages during the course of work. Upon completion of the installation of the site covers, it is possible to restore the well cover alarm to a permanent state of defence by controlling the cloth.
- Remote Upgrade
A unique IAP system program, smart application download, MD5 validation, allows for remote upgrade of smart-cover equipment through a system platform.

|---|---|---|---|
| 1 | Status monitoring | River cover flip/dispatch alert | A high-precision attitude sensor is incorporated, which triggers immediate alarm when the well covers are illegally opened, tilted or abnormally flipped. |
| 2 | Environmental awareness | Water Spill/Infiltration Monitoring | Support the extension of the spill-monitoring function, which provides a full network-based warning of spills to backstages when wells reach the alert level or equipment is flooded for long periods of time. |
| 3 | Wireless Transfer | NB-IOT Report low-capacity | A network of narrowband hives with a strong underground and well-circle penetrating capability to ensure that data are stabilized and uploaded in harsh underground environments. |
| 4 | Smart Power | HPC Dynamic Combined Power Supply | The NB-IOT launch needs to be addressed through the Super Capacitive (HPC) for an instant pulse current, effectively extending the life of lithium batteries and guaranteeing high and reliable discharge at extreme temperatures. |
| 5 | Transport security | Battery power low voltage alert. | The equipment is self-inspected on a regular basis and reports on its operational status, and maintenance alerts are automatically issued when battery power is below the set threshold to facilitate replacement by municipal personnel as required. |
| 6 | Damage-proof design | Dismantling/disrupting mechanisms | High-intensity technical-grade PC casings, resistant to pressure, shock and acid-resistant alkali corrosion. Strongly equipped with a high level of protection against malicious damage, in conjunction with the bottom of the well covers. |
