Abstract
Abstract A display system is provided for a monitoring and alarm system. The monitoring and alarm system includes a central processing unit (10) and a plurality of sensors (14) polled by the central processing unit. A display which is part of the central processing unit is used to prompt user inputs to group a plurality of the sensed variables and the states and limits of each of the variables in a group. The display system is employed by the user to generate a schematic display of the system or environment being monitored. In the process of generating the schematic display, the user links alarm areas on the schematic display with a group or single variable defined by the user. In addition, the user links message areas on the schematic display with user defined messages to be displayed in the event all the conditions defined by the states and limits of variables in a group are true. After each schematic has been generated, it is stored together with the data defining the linked areas of the display. A stored schematic display may then be invoked, and once invoked, messages and status conditions are displayed in response to the sensed conditions of groups of variables sensed by said monitoring and alarm system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A display system for a monitoring and alarm system, said monitoring and alarm system including a central processing unit, a plurality of sensors polled by said central processing unit to provide output signals representative of sensed variables to said central processing unit, display means for receiving user inputs to group a plurality of said sensed variables and the states and limits of each of the variables in a group, each group having at least one variable, means controlled by said central processing unit in response to all the conditions defined by the states and limits of variables in a group being true for generating alarms and messages, said display system comprising: means for interactively generating on said display means a schematic display of the system or environment being monitored, and means for dynamically linking alarm areas on the schematic display with a group or single variable defined by the user.
Claim 2
Dependent Claim
150 words
A display system for a monitoring and alarm system, said monitoring and alarm system including a central processing unit, a plurality of sensors polled by said central processing unit to provide output signals representative of sensed variables to said central processing unit, display means for receiving user inputs to group a plurality of said sensed variables and the states and limits of each of the variables in a group, each group having at least one variable, means controlled by said central processing unit in response to all the conditions defined by the states and limits of variables in a group being true for generating alarms and messages, said display system comprising: means for interactively generating on said display means a schematic display of the system or environment being monitored, and means for dynamically linking alarm areas on the schematic display with a group or single variable defined by the user.
Claim 3
Dependent Claim
45 words
The display system recited in claim 1 further comprising means for dynamically linking message areas on the schematic display with user defined messages to be displayed in the event all the conditions defined by the states and limits of variables in a group are true.
Claim 4
Dependent Claim
31 words
The display system recited in claim 2 further comprising means in said central processing unit for storing each schematic display generated together with data defining the linked areas of the display.
Claim 5
Dependent Claim
51 words
The display system recited in claim 3 further comprising means for invoking a schematic display stored in said central processing unit, said display means then displaying messages and status conditions on said schematic display in response to the sensed conditions of groups of variables sensed by said monitoring and alarm system.
Claim 6
Independent Claim
104 words
A method of providing a display for a monitoring and alarm system comprising the steps of interactively generating on a computer screen a schematic display of the system or environment being monitored, dynamically linking alarm areas on the schematic display with a group or single variable defined by the user, dynamically linking message areas on the schematic display with user defined messages to be displayed in the event all the conditions defined by the states and limits of variables in a group are true, and storing in computer memory each schematic display generated together with the data defining the linked areas of the display.
Claim 7
Independent Claim
104 words
A method of providing a display for a monitoring and alarm system comprising the steps of interactively generating on a computer screen a schematic display of the system or environment being monitored, dynamically linking alarm areas on the schematic display with a group or single variable defined by the user, dynamically linking message areas on the schematic display with user defined messages to be displayed in the event all the conditions defined by the states and limits of variables in a group are true, and storing in computer memory each schematic display generated together with the data defining the linked areas of the display.
Claim 8
Dependent Claim
52 words
The method according to claim 5 wherein the step of dynamically linking alarm areas comprises the steps of selecting an option to associate an area on the computer screen with an alarm, pointing to starting coordinates of said area, and drawing a geometrical figure around said area beginning at said starting coordinates.
Claim 9
Dependent Claim
41 words
The method according to claim 6 wherein the step of dynamically linking message areas comprises the steps of entering a variable or an alarm/action name, and pointing to the value area on the computer screen for the named variable or alarm/action.
Claim 10
Dependent Claim
62 words
The method according to claim 5 wherein the step of storing comprises the steps of creating a first file for saving the interactively generated schematic display, and creating a second file for saving the dynamically linked display information, said second file containing a first record specifying how many records are in the file and a plurality of records containing the linking information.
Claim 11
Dependent Claim
43 words
The method according to claim 8 further comprising the steps of invoking a stored schematic display, and displaying messages and status conditions on said schematic display in response to the sensed conditions of groups of variables sensed by said monitoring and alarm system.
Claim 12
Dependent Claim
50 words
The method according to claim 9 wherein the step of invoking comprises the steps of creating a data base of variables, alarm/action entries and dynamic display entries from said first and second files, and acquiring data of the sensed variables and checking the logical groups, if any, of the variables.
