Introduction

The main objective of this project is to establish centralized monitoring & reporting station at

Master station. All Mother & daughter station are connected to Master station through GPRS as

primary network and WAN as standby network. RTU's are established at all stations (mother &

daughter station) to integrate the all local field instruments and to established serial

communication with various other third party devices.

The objective is to view various online parameters of mother station and daughter station at

Centralized location, which helps to manage CNG supply at various location of TNGCL.

The architecture comprises:

a. Master Control Station (MS)

b. Local HMI station

c. Large screen display

d. RTU
