Business Challenge

The client provided remote and onsite facilities management services through a proprietary PC based building management software application. The system is a is a Web-enabled solution powered by the NiagaraAX Framework®, that can integrated into LONWORKS®, BACnet®, Modbus™ and other protocols. The software was in need of an upgrade, with the ability to interface with other 3rd party systems running in the building – lighting, air conditioning etc

The client approached Silicus to re-engineer the existing Building Management System (BMS) with following key requirements:

  • The BMS should interface with newer mechanical and electrical systems such as ventilation, lighting, power systems, fire systems, and security systems for building control
  • Use of BACnet and Modbus to control the interfaces between the system and end devices
  • High customization features such as reports, create user screen, real time data access, etc.

Silicus Solution

  • Integration of BACnet using Chipkin
  • Integration of Modbus using Modbus4j Stack

The front end UI was re-designed and enhanced using Jquery, HTML5 and CSS3. The BMS was powered by a hybrid database for higher performance, low memory footprint and lower cost. The hybrid databases consisted of:
