Vizion Central Management System (CMS) provides an infrastructure to allow for the remote monitoring and control of the streetlighting inventory. This is provided by the installation of a communication network, and equipment within each asset to provide this monitoring and control. The data to, and from the system is controlled by a database server (called a Vizion Host) acting to provide this monitoring and control.
A Vizion CMS system provides four fundamental functions:
1. control of switching regimesA Vizion CMS system provides five fundamental benefits
1. Control of costsThese translate into innumerable individual benefits:
• Provides convincing cost-benefitExisting control regimes are inflexible and it is both expensive and slow to implement new regimes. To change a switching level (say from 70Lux to 55Lux) would require all photocells to be replaced, incurring both the cost of the replacement photocells, and the labour cost of undertaking the change. This forms both an impediment to undertaking changes in the control regime, and restricts the rate at which a change can be made.
In stark contrast CMS allows for the rapid deployment of alternative regimes. The cost of deployment is very low, for example a revision to a multi-stage part-night dimming regime could be implemented in a few minutes and deployed to all streetlights within a few hours.
The drive for CMS is not the ability to exercise complex control, but to use advanced control to reduce energy consumption. A further aspect is that a CMS installation provides luminaire status information allowing very accurate determination of the maintenance requirements.
