The present invention relates to a system to display information concerning the status of various components of a building's automation and security systems. More specifically, it relates to a system for the pictorial display of such information for a past time or time period.
It is becoming ever more important for owners and managers of commercial buildings to be able to create and maintain:
1. safe buildings;
2. comfortable buildings; and
3. efficient buildings.
In order to do so, these owners and managers rely heavily on electronic building automation systems, for the control of processes such as heating, ventilation, and air conditioning, and electronic security systems for the control of processes such as physical access, both to the building and to various parts of the building, and information access.
It is important for the owners and managers of a building to be able to study building conditions that occurred in the past. Using building status information gathered from a past time or time period, a building's owners or managers can analyze the performance of the building's automation and security systems. For example, a building manager may, among other uses, use this information to
1. determine the cause of an equipment failure (and how to prevent that failure in the future);
2. determine the cause of an undesired environmental condition (and how to prevent that condition in the future); and
3. to study trends.
The more clearly this historical status information can be presented, the more effective a building manager can be in his analysis.
Currently, a building manager can view this historical status information in the following ways:
1. Logs—A list of values or messages from the building automation or security system that are stored along with timestamps indicating the time at which each value or message was recorded. These lists are viewed in their raw form as simple text tables. Logs can be used to capture several types of historical data:
2. Charts—Values from historical logs that are plotted against time. These Charts may also show a statistical representation of the values such as averages and standard deviations. A given Chart may also contain data from multiple historical logs. Charts may also be interactive permitting the user to move forward and backward in time and to determine which Logs to display.
3. Reports—Logs may be assembled into a Report. A Report may be simple text from Logs or Charts. Reports may also contain a combination of Logs and Charts. Although these Charts and Reports make it easier to understand historical status information than Logs alone do, there is some information that cannot be clearly represented even by using Charts and Reports. The deficiency is most noticeable when trying to correlate data from multiple Logs. For example, a Chart may be able to show an air supply temperature and the status of a fan within an air handler at a particular time a week ago, but it does not show how the supply temperature is or is not affected by the fan and its status. It is an object of the present invention to show more clearly how the condition of one or more components of building automation and security systems affect one or more other components of security systems.
Unfortunately, there are deficiencies in conventional systems of logs and charts that lead to lack of recognition of relationships between systems. Furthermore, conventional graphical displays show only current data and not historical data.
In contrast to the above-described conventional systems, the system for analyzing building systems presents data in such a form that allows for ease in correlation of various systems. The system and method graphically show information and spatial relationship in the building.

In one embodiment, the interface device 28 is a keyboard and a pointer controller such as a mouse or tracker ball. In another embodiment, the interface device 28 and the graphical display screen 30 are incorporated into one device as a touch screen 32.
The system 20 in addition, has a library or database 34 of the building. The library 34 is accessible by the controller 26 to display images or representations of the building or portions of the building 36, such as shown in
The system 20 is for analyzing a building system. The building system can have subsystems and/or elements. For example, in discussions regarding

As explained in more detail below, the data can come in various forms such as the temperature or the relative humidity which would vary over a range or the data is simple if a device is on or off, such as a light or fan. However depending on the devices, items such as lights or fans may have various levels while in the on mode, such as low, medium, or high.

While default rates are typically set, a user could configure the sample rate. Furthermore, the system 20 could have controls wherein the element 24 monitored starts sampling at a higher rate when some trigger is reached. For example, if the system 20 is monitoring room temperature and recording every ten minutes, the element 24 monitored could automatically increase the rate of sampling of the temperature and other elements such as fans, heating, and cooling elements if the temperature drops below 60° F. or rises above 80° F.
Typically the system 20 will be gathering and storing data in the data loggers 22, as seen in
In addition to the elements 24A to be analyzed, the user selects other elements 24O to view concurrently as represented by decision diamond 58. While elements 24A to be analyzed are broken out from other elements 24O, the system 20 does not typically distinguish whether the element is analyzed or another element. All the elements 24 get projected onto a screen. In this embodiment, it is the user, not the system 20, which determines which element 24 is influenced by an other element 24; that is the relationship between elements 24.
The user may select the region of the building to view as represented by decision diamond 60. The user can select the region by clicking regions or graphically selecting a region on the screen 30.
In one embodiment, the system 20 defaults to a region that includes all elements to be viewed and extends to the next wall 38 in the building 36 as seen in
Values for the components may be represented as text, but they may alternatively or simultaneously be represented pictorially. For example, the status of a fan 46 or 48 may be shown by “ON” when in operation or by spinning fan blades as for fan 48. The status of a fan may be shown by “OFF” when not in operation or by stationary fan blades as for fan 46. Along with each individual measured value, the pictorial or graphical display 30 shows the relation of the components, the elements 24, to each other and to a section of the building 36 such as here with a specified floor.
Thus, a preferred embodiment of the present invention is a method to pictorially view pictorial information contained in logs of building automation and security systems for a past time or time period. A building manager can, therefore, view information concerning various components, how the components relate to one another, and how the condition of one component may have affected the condition of another component. For example, as shown in

The system 20 can be configured in numerous ways regarding the selection of the elements 24 monitored. The system 20 can be configured such that a user selects a single component or element 24 with a specific defined location. One alternative would be to select a system (or element) 24, such as a cooling system, that covers a large portion of the building and has numerous monitoring locations. The system 20 determines what monitoring locations or data points need to be included as represented by block 68. The monitoring locations are determined based on several factors including the region of the building selected to be graphically represented. For example, if the cooling system was selected in the embodiment shown in

While the graphical display 30 is shown in this patent as a black and white figure, the graphical display 30 is in color in an embodiment. The temperature gauge in addition to moving vertically also has color changes from blue to red as the temperature increases.
While elements 24 monitored are generally contemplated to be mechanical systems such as lights and heating, it is recognized that other elements 24 could be monitored such as the number of persons in a room. Referring to
The three rooms, room one 86, room two 88, and room three 90 are connected and air can flow between the rooms 40. Each room 40 has a temperature sensor or monitor 44 and a bar graph 76 representing the temperature. Each room has an air handling system or element with a series of fan symbols on the display 30 to symbolize the location of the vents. It is contemplated that the system 20 has a series of detectors to approximate the number of persons in a room 40, for example, a detector at each entrance/exit. The dash line 92 represents the split between room one 86 and room two 88.

The Logs of building automation and security systems can be converted to such a pictorial display in any of a number of methods known to those skilled in the art. Moreover, the pictorial display may be interactive, allowing a building manager to change the time or time period for when values are displayed. Furthermore, the pictorial display can be playable like a video player. A building manager can play the display either forward or reverse, real-time speed, slow, fast, or record-by-record.
When a building manager can clearly see information concerning individual components of the building automation and security systems, how the components relate to one another, and how the conditions of one or more of the components may affect the conditions of one or more other components, he can assess the conditions more rapidly and more accurately, and as a result, take better action to improve the building's efficiency, occupants' safety, and occupants' comfort.
