Definitions

  • This invention relates to a computer-implemented method for controlling an alarm display unit having a display area, wherein a list of alarm events generated by alarm sensors is displayed on a first display part area, If necessary, a dialog box for processing the alarm events and on a second display section if necessary, alarm data of the alarm units are displayed on a third display area.
  • An alarm display unit has a limited area.
  • alarm events occurring in a region are displayed immediately after the occurrence and detection of the alarm event by means of an alarm sensor on the alarm display unit. If several consecutive alarm events occur, they can be displayed by pop-up windows or in the form of lists. The user quickly no longer has an overview of which alarm event the user should first process.
  • the user also does not receive any information about the probability of the respective alarm event actually having occurred.
  • the latter is particularly important because of the possibility of false alarms. According to common teaching, there is the problem of false alarms, especially in systems with video surveillance.
  • a range is meant a spatially defined range.
  • the area can be defined by borders.
  • an area may be a property or part of a property.
  • the method described below can be applied to area portions of the area, respectively.
  • a security concept is created for an area.
  • the user can perform alarm events as he pleases.
  • the user decides after his conscience or after his Mood which alarm event is being processed and when.
  • the user also decides according to his conscience whether he classifies an alarm event as an actual alarm event or as a false alarm.
  • the invention disclosed here has the task of making the processing of the individual alarm events more effective and independent of the subjective influences of the user.
  • One of the purposes of the task more effective processing of the alarm events is to be understood, inter alia, that the user is able to process multiple alarm events in a time span.
  • the more effective handling of the alarm events is also to be understood in such a way that the user establishes or maintains the security of the area by processing the alarms identified by the method according to the invention.
  • the principal solution of the invention disclosed here is that the individual alarm events can be arranged with regard to their importance and / or their probability of actual occurrence. Another solution is to specify to the user in which order the user must process the alarm events, the currently processed alarm event and the further processed alarm events are displayed.
  • the solution of the method according to the invention provides for the incoming alarm events to be sorted according to their priority value so that the alarm events are available in a manner that is clear to the user.
  • the priority value may be a percentage of the relevance of the alarm event, with one hundred percent being very relevant, for example and zero percent may not be relevant.
  • the method according to the invention thus offers the effect of the objective processing of the alarm events, which precludes the user being able to process the alarm events according to a subjective discretion.
  • the user when using the method according to the invention, can only process the alarm event, which alarm event is evaluated as the alarm event with the highest priority value.
  • This also includes that several alarm events can be arranged according to their priority values for processing by the method according to the invention.
  • Alarm sensors usually need to be maintained to avoid false alarms. During maintenance, the condition of the alarm sensor is documented. An alarm event displayed by a poorly maintained alarm sensor or a bad event by an alarm sensor may have a lower priority than an alarm event displayed by a regularly maintained alarm sensor or by an alarm sensor in a good condition.
  • the security concept may include provisions with which priority factor the maintenance of an alarm sensor is assessed.
  • the person skilled in the art also understands the property of the alarm sensor to detect an alarm signal. This property is influenced by the quality of the measurement that can be implemented with the respective alarm sensor and / or by the surroundings of the alarm sensor.
  • image sensors and / or acoustic sensors as an alarm sensor is known to those skilled in the relevant documentation, which can be measured image signals or audio signals recorded with a quality recorded in the relevant documentation.
  • the object to be measured with the respective image sensor must have a minimum size and / or a minimum contrast to the environment in order to achieve a certain quality of the measurement.
  • a sound signal must have a minimum volume at the acoustic sensor.
  • environmental influences such as exposure, weather influences can distort these image signals and / or audio signals.
  • the saturation can be determined. This can be simplified, for example, in such a way that the number of pixels near saturation is determined as a proportion of the total pixels.
  • the saturation value thus obtained scales between 0 and 1, whereby the saturation values between 0 and 0.1 can be assigned the highest priority factor.
  • the saturation values between 0.1 and 1 may be a linearly varying priority factor which has its maximum at a saturation value of 0.1 and a minimum at a saturation value of 1.
  • a weather station with a further sensor, which further sensor is not an alarm sensor and can deliver, for example, a wind speed or other weather data.
  • wind can reduce the quality of the measurement by means of the image sensor, since the camera sensor is oscillated, for example due to the wind pressure.
  • a permissible wind speed is selected or predefined in the safety concept, up to which wind speed the highest priority is given and thus the image sensor supplies measurements with a minimum of quality. It is believed that at higher wind speeds, the quality of the measurement by the image sensor is linearly reduced to a minimum value (about 0). Furthermore, a maximum wind speed is selected for a minimum quality of a measurement by means of an image sensor.
  • the pertinent documentation may, for example, identify a susceptibility to error or inaccuracy of a measurement by means of a specific sensor or a deviation from a measuring range selected by the properties of the measuring sensor, from which error susceptibility or inaccuracy a priority factor regarding the state of the alarm sensor can be determined, taking into account, if appropriate, weighting factors is predetermined by the security concept.
  • the person skilled in the art can also determine the priority factor regarding the status of the alarm sensor from his experience and / or based on the security concept created for a property.
  • the security concept may include an indication of which priority factor is assigned to the respective alarm event.
  • the security concept may include an indication at which frequency of an alarm event which priority factor is assigned.
  • the inventive method may include a determination that the number of times the alarm event is weighted by a factor or a function.
  • the security concept may include a further indication of which priority factor is assigned to an alarm event in conjunction with another alarm event.
  • a room can be monitored by means of a plurality of alarm sensors, wherein one alarm sensor detects an alarm event and another alarm sensor detects another alarm event.
  • An alarm event detected by the alarm sensor can be verified by the detection of another alarm event by means of another alarm sensor, if the alarm event and the further alarm event are events that are directly related.
  • the priority factor of the alarm event may be higher than in no verification of the alarm event. In the latter case, the priority factor may be zero or nearly zero.
  • Assigning a priority factor to an alarm event in response to the occurrence of a linked alarm event may include assigning to the alarm event and the further alarm event a similar sum of priority factors or a similar product of priority factors.
  • the alarm event and the further alarm event are displayed in the list at adjacent, preferably adjacent positions. This optionally allows the simultaneous execution of both alarm events, whereby the execution of the alarm events by the inventive method is made more effective.
  • the priority factor and / or the priority value can be a numerical value, by means of which number specification the meaning of an alarm event or an alarm event in conjunction with another alarm event is evaluated with reference to the security concept created for a zone.
  • the priority factor and / or the priority value can be represented with colors as a function of the numerical value.
  • the priority factors and / or the priority values of an alarm event were displayed with the colors of a traffic light (red: high priority, yellow: medium priority, green: low priority).
  • the priority factor and / or the priority value can be represented graphically by means of a surface element filled in as a function of the numerical value.
  • the priority factor and / or the priority value in addition to or as an alternative to the evaluation of the importance of one or more alarm events, may include a number indicating by means of which number the probability of the actual occurrence of the alarm event or alarm events is indicated.
  • Ordering alarm events directs the user to consider the highest priority alarm event. This triggers the user to an order of processing the alarm events.
  • a programmer is entitled to create the specifications such as the given priority factors or the specification of the priority factors.
  • the programmer can for this purpose create a list in which list priorities are assigned to the alarm events with reference to a security concept for a property.
  • the method according to the invention can include the summation of the individual priority factors for calculating a priority value, wherein the term summation can be understood to mean a subtraction of individual priority factors. Likewise, the priority factors can be multiplied to a priority value.
  • the disclosure of the invention includes that the person skilled in the art combines various mathematical methods for calculating the priority value.
  • Priority values for the occurrence of a priority factor or for the occurrence of multiple priority factors can be predefined here.
  • the method of the invention includes evaluating the occurrence of an alarm event and the occurrence of another alarm event, which further alarm event is associated with the alarm event, with a priority value defined by the programmer.
  • the method according to the invention can be characterized in that the dialog box for processing an alarm event displayed in the list is displayed in the second display sub-area.
  • the user can thus only process the alarm event with the highest priority.
  • the system thereby becomes resistant to changes in the importance of the alarm events by the user.
  • the user is thereby deprived of the possibility of negating an alarm event, or of processing the alarm events according to his subjective feelings, his mood or at his discretion. This is especially the case when a signal is issued to a person superior to the user if a high priority alarm event is not processed within a defined period of time.
  • the method according to the invention can be characterized in that the alarm data measured by the alarm sensors of an alarm event displayed in the list is displayed in the third display sub-area.
  • the alarm data of the alarm event with the highest priority can be displayed in the third display area.
  • the alarm data may include, for example, image data which image data is captured by a camera directed to the area.
  • the display part areas can be arranged from left to right or from top to bottom.
  • the arrangement of the display areas corresponds to the usual reading direction from left to right and the direction of the processing of individual alarm events.
  • the display part surfaces can be arranged in a direction from top to bottom and thus with each other.
  • FIG. 1 illustrates the inventive method for controlling an alarm display unit with a display surface 1. It is displayed in the alarm display unit by an alarm event occurring in an area and / or occurred event. The event is detected by a sensor monitoring the area.
  • the sensors SENSOR1 to SENSOR5 shown as an example, which sensors - as shown below - monitor in part their own areas and partly common areas.
  • the sensors SENSOR1, SENSOR2, SENSOR3 form a subsystem 11.
  • the display area 1 is subdivided in principle into three partial areas, which are referred to as the first display partial area 2, the second display partial area 3 and the third display partial area 4.
  • the display part surfaces 2, 3, 4 are arranged side by side in the sense of the processing of the individual alarm events described below and a processing direction 10 resulting therefrom.
  • the first display part surface 2 is arranged to the left of the second display part surface 3 and the second display part surface 3 to the left of the third display part surface 4. This arrangement of the display part surfaces 2, 3, 4 from left to right follows the idea of common reading direction in Europe.
  • the alarm sensors SENSOR1 to SENSOR5 give messages to an alarm center 12.
  • the programmer assigns a priority factor to each alarm event and each state.
  • priority values are calculated from the priority factors or - if priority values are predetermined - retrieved.
  • Registered subsystem 11 includes the three sensors SENSOR1, SENSOR2 and SENSOR3.
  • a door lock comprises the SENSOR1, a motion detector for detection by the entrance of moving persons or animals the SENSOR2 and a surveillance camera the SENSOR3.
  • SENSOR4 and SENSOR5 are independent sensors.
  • the sensor SENSOR2 and the sensor SENSOR3 give a message as to which message is to be considered an alarm due to an inactivity of the sensor SENSOR1.
  • the message of the sensor SENSOR1 has a priority factor of 1.0.
  • the message of the SENSOR2 and SENSOR3 sensors has a priority factor of 2.0.
  • the alarm event generated by the passage of a person through the entrance thus has a first priority value of 5.0 when summed and a second priority value of 4.0 when multiplied.
  • the programmer may assign a third priority value of 10.0 if the sensor SENSOR1 does not report, but the sensors SENSOR2 and SENSOR3 give a message, as in this case a high probability of an improper passage through the input can be assumed.
  • the sensor SENSOR4 can monitor an area of lesser importance.
  • the sensor SENSOR4 may indicate that there is no water in a water tank.
  • a message from the sensor SENSOR4 may have a priority factor of 0.1. There If no other sensors are coupled to the SENSOR4 sensor, the priority value is equal to the priority factor and is 0.5.
  • the sensor SENSOR5 may be a smoke detector in a kitchen, with a SENSORS5 message not having a priority factor of 1.0. A repeated and non-permanent detection of smoke in the kitchen can not indicate an emergency, so the priority value is formed by a reduction of the priority factor by half. The priority value of the message of the sensor SENSOR5 is thus 0.5.
  • the highest priority alarm event 8 is ranked at the top of the list 5. The user is thereby instructed to process the alarm event in the area of the input.
  • FIG. 1 illustrates the case that the dialog box 6 for processing the alarm event with the highest priority is displayed in the second display part area 3. No further dialog boxes are displayed in the second display part area 3, so that the user can only process the alarm event with the highest priority.
  • the exclusive display of the highest priority dialog box 6 for processing the alarm event with the highest priority prevents the user from selecting the alarm event to be edited as he pleases and creating a threatening situation. The user thus can not work the alarm event regarding the smoke in the kitchen.
  • the sensor data 7 of the alarm units are displayed in the third display area 4.
  • FIG. 1 illustrated embodiment of the inventive method relates to the case that the sensor data 7 of the alarm event with the highest priority greater than the alarm data of the other sensors are shown. This draws the user's attention to the highest priority sensor data 7.
  • FIG. 1 the sensor data 7 are shown with the highest priority image data 9 in a priority position.
  • FIG. 2 illustrates a further possible application of the method according to the invention.
  • the FIG. 2 shows the floor plan of a room 13 as an area, which room 13 is defined by walls 14 as boundaries.
  • One of the walls 14 comprises a door 15, via which door 15 only the space 13 can enter and leave.
  • the door 15 is monitored by an alarm sensor 16.
  • the alarm sensor 16 may be a sensor according to the prior art, which alarm sensor 16 detects an alarm event when opening the door 15.
  • the further alarm sensor 17 may be a sensor according to the prior art.
  • Opening the door 15 causes a movement in the room 13, namely at least the movement of the door 15 or moving a in FIG. 2
  • a person in the room 13, not shown, is detected by the further alarm sensor 17 as a further alarm event.
  • the alarm event is verifiable by the further alarm event.
  • the priority of the alarm event can be assigned a value of one. It can thus be assumed with a high probability that the alarm event actually occurred.
  • the priority of the alarm event can be assigned a value less than one. It is therefore uncertain whether the alarm event actually occurred.
  • FIG. 3 illustrates one way of displaying an alarm event.
  • the illustration includes a video image 18 taken with a prior art video sensor.
  • object detection of the video sensor can act as an alarm sensor, so that an alarm event is generated via the video analysis, for example, when a car 19 is detected in the video image 18.
  • the current experience is that just the common doctrine of video analysis is error-prone.
  • the representation of the alarm event in FIG. 3 includes a list of parameters 20 such as trajectory, brightness, contrast, et cetera, which parameters 20 indirectly affect the state of the video sensor directly or via the video image output from the video sensor.
  • the representation comprises a parameter priority 22 for each of these parameters, the priority 21 of the Alarm event is calculated as an average of the parameter priorities. The calculation of mediocrity is done according to standard teaching.
  • the priority 21 is represented by numbers, by color and by means of a filled area.
  • the word false alarm is located at one end of the area and the word real alarm at the other end.
  • a priority 21 in the amount of 20% is calculated from the parameter priorities 22, which is rather to be regarded as a false alarm.
