Abstract
A building control system, such as an HVAC system, has a field unit incorporating a control panel (a field panel) with a local user interface allowing user selected parameters for collecting trend information when the system detects a change of value for a point in the system or a timed instruction in the memory of the field panel to begin collecting trend data for a point. The resulting trend data collected by the field panel can be uploaded to a workstation in the building control system, where the trend data can be formatted into a report, and then digitally authenticated.
Claims27
A method of operating a building control system, the method comprising the steps of:
- receiving user generated parameters for collecting trend data at a field panel of the building control system;
- storing trended data collected by said field panel regarding said user generated parameters at the field panel;
- and
- transmitting the stored trended data regarding the user generated parameters at the field panel to the workstation.
10 The method according to claim 1, wherein the field panel further comprises an object-oriented database.
The method according to claim 11, wherein a plurality of user generated parameters for a collecting trending data for a plurality of points in said building control system are stored in said object-oriented database.
A building control system comprising:
- a workstation;
- and
- a field panel in communication with the workstation;
- the field panel operative to receive user generated parameters for collecting trend data at a field panel of the building control system, store trended data collected by said field panel regarding said user generated parameters at the field panel, and transmit the stored trended data regarding the user generated parameters at the field panel to the workstation.
The system of claim 17, wherein the field panel is further operative to transmit the stored trended data temporarily stored in a buffer when a user selected percentage of the buffer is full.
