IoT Cover(Telephone Line)

Introduction

Through telephone line power feeding and DTMF communication, the manhole cover switch, manhole cover status, combustible gas, temperature and humidity, vibration and other sensors are controlled to achieve manhole cover monitoring in high-confidentiality occasions.

Service Content

Manhole cover structure design and development, waterproof and anti-condensation

Development of mechanical parts for manhole cover switch locks, unlockers, and mechanical unlocking

Manhole cover control panel software and hardware development

Development of power supply modules, communication boards, and business boards in the central office communication frame

Joint debugging of the entire system and docking of the information and innovation system

Technical Difficulties

Manhole cover structure is waterproof, antifreeze and anti-condensation

With sensors for combustible gas, temperature and humidity, vibration, etc.

Mechanical unlocking should be convenient, with unlocking device and mechanical breaking unlocking device.

Single telephone line 1 to 10 for power and communication

Built-in power management modules such as telephone line power supply and power storage

Telephone Line DTMF Communication Module

Central office power supply and communication service board

Central office communication board and information innovation system connection

Centralized management at the local end, one local end can connect to up to 2560 manhole covers

Manufaturing

The structure is complex and the production is difficult.
