System structure Introduction

The entire system uses an open, distributed system architecture.Do "distributed control, centralized management, information sharing",The monitoring management system specifically includes:


Tank capacity measurement subsystem

Using EMERSON's high-precision radar level gauge,High static pressure transmitter,Multi-point thermometer and TANKMASTER tank capacity calculation software.


Data acquisition and monitoring management subsystem

Using the GE PAC 3i controller and its process I/O set,2 sets of upper computer system,Use GE CIMPLICITY HMI industrial configuration software.


Process control instrument

Adopting domestic top electric cut-off ball valve,3051 transmitter,E+H tuning fork level switch,French FM spiral wheel flowmeter and so on.


Fire alarm subsystem

The fire system adopts Beijing Lida fire alarm button and controller,The flammable gas alarm system adopts Shenzhen Tean Company ES2000 series products.


Transceiver monitoring and management subsystem

Adopting Hongyi AWZC series loading management system and its software,On-site equipment includes:French FM loading flowmeter,EMERSON 788 electro-hydraulic CNC valve,Overfill Grounding protector.etc


Network and remote service sharing system

Data monitoring data transmission to the production management office and customs.


System screenshot

The system is closely integrated with the automatic control of the tank area.And can display the liquid level, temperature and even pressure changes of the tank in real time in the form of a graphical interface:
