Abstract

Event inputs, each belonging to one of predefined event categories, are received from event status reporting units. A time period, a time duration within which the event inputs were received, is segregated into an ordered sequence of time slots. Inputs are categorized according to the time slots and the event categories. Ranks, based on weights of unique event inputs, are assigned to each of the predefined event categories within each of the time slots. A count of symbols for each time slot is defined. Each symbol represents a unique predefined event category. The time slots and the defined count of symbols ordered according to the ranks of the respective predefined event categories represented by the symbols for each of the time slots are displayed. Each symbol includes an indication of the weight of unique event inputs categorized for the selected predefined event category and for the selected time slot.

5. The method of claim 1, wherein at least one of the event status reporting units is a sensor, and at least one of the predefined event categories is readings of the sensor, and

wherein the event inputs belonging to the predefined event category are the readings having predetermined characteristics.

6. The method of claim 1, wherein at least one of the event status reporting units is an input device configured to receive inputs manually, and at least one of the predefined event categories is inputs received by the input device, and

wherein the event inputs belonging to the predefined event category are the inputs having predetermined characteristics.

7. The method of claim 1, wherein the processor is a programmable logic controller.

8. The method of claim 1, wherein displays are represented graphically having an x-axis representing the time slots and a y-axis representing the ranks, and

wherein the symbols are 2-dimensional shapes having an enclosed area, and the indication of the weight of unique event inputs within the symbols is provided by demarcating a section of the enclosed area corresponding to the weight of unique event inputs.

9. The method of claim 1, wherein the symbol representing a given unique predefined event category within a given time slot displayed on the display unit has connecting bands associated with the symbol when the symbol representing the given unique predefined event category appears within at least two of the given time slots displayed on the display unit, and

wherein the symbol representing the given unique predefined event category within the given time slot displayed on the display unit is connected by the connecting bands to the symbols representing the given unique predefined event category within time slots adjacent to the given time slot.

10. The method of claim 9, wherein the connecting band associated with the symbol representing the given unique predefined event category within the given time slot starts from the symbol and ends at a pre-designated area in the graphical representation when the symbol representing the given unique predefined event category is absent from within the adjacent subsequent time slot, and

wherein the connecting band associated with the symbol representing the given unique predefined event category within the given time slot starts from the pre-designated area and ends at the symbol when the symbol representing the given unique predefined event category is absent from within the adjacent previous time slot.

11. A user interface for monitoring technical equipment, the user interface comprising:

a data interface configured to receive a plurality of event inputs from one or more event status reporting units, wherein each event input of the plurality of event inputs belongs to one predefined event category of predefined event categories;
