CONTROL UNIT FOR AN ALARM CENTER, ALARM SYSTEM AND METHOD FOR OPERATION OF AN ALARM CENTER

Description

[0001] The present invention relates to a control unit for a hazard alarm control center, for example a burglar alarm, fire alarm and / or extinguishing control center, a hazard alarm system, preferably a fire alarm system, and a method for operating a hazard alarm control center, for example a burglar alarm, fire alarm and / or extinguishing control center.

[0002] Hazard detection systems, especially fire detection systems, are generally well known. Hazard detection systems typically comprise a hazard detector and a signal-processing control unit. The hazard detector can be a fire detector, for example. Hazard detectors are used primarily to detect hazard parameters such as toxic gases, combustion gases, flames, and sparks.

[0003] Control units are typically provided in alarm control panels, such as intrusion, fire alarm, and / or extinguishing control panels. Alarm control panels typically have a display and control component. Such a display and control component can be used, for example, to configure system configurations and / or assign faults or alarms to a corresponding alarm detector.

[0004] Since a hazard detection control panel is a safety-relevant component of the hazard detection system, the aforementioned assignment of faults or alarms to a corresponding hazard detector must be carried out quickly. However, current hazard detection control panels are often characterized by the time-consuming nature of detecting faults or alarms and also assigning them to the corresponding hazard detectors.

[0005] Furthermore, the displays can be confusing, making it difficult for users to quickly and reliably identify the message. Messages are typically displayed in list form. However, the rapid detection and identification of a fault or hazard is particularly important in the safety-related area of ​​hazard detection systems, requiring short response times.

[0006] The German Patent and Trademark Office has searched the following prior art in the priority application for the present application: US 5,297,252 A and US 2016 / 0300460 A1.

[0007] US 2003 / 097188 A1 discloses a control unit for a security alarm control panel. A user interface for controlling and displaying information about devices in a system is described in detail. The user interface is designed to meet the needs of different user types. A user unfamiliar with the system is presented with a customized message on the user interface display. A user with limited experience in using the interface can be provided with one or more specialized input devices to obtain further information about the system. A more experienced user has access to a touchscreen that allows them to control devices via the user interface.

[0008] Against this background, it is an object of the present invention to provide a control unit for a hazard detection control panel, for example, an intrusion, fire alarm, and / or extinguishing control panel, a hazard detection system, preferably a fire alarm system, and a method for operating a hazard detection control panel, for example, an intrusion, fire alarm, and / or extinguishing control panel, which reduce or eliminate one or more of the aforementioned disadvantages. Furthermore, it is an object of the invention to provide a solution that enables faster detection of an alarm and / or a fault by an operator of a hazard detection system.

[0009] According to a first aspect of the invention according to claim 1, the object mentioned at the outset is achieved by a control unit for a hazard alarm control center, for example a burglar alarm, fire alarm and / or extinguishing control center, wherein the control unit is configured to receive a first signal characterizing the hazard situation from a hazard alarm for detecting a hazard situation, - comprises a user interface designed as a touch-sensitive input and output screen with a display means configured to display an idle display and / or a message display, wherein the idle display is displayed by the display means if there has been no interaction with an operator of the hazard alarm control center and the control unit for a predetermined period of time, wherein the message display is called up by the operator,when the user taps on the display means when the idle display is displayed, and wherein a number of messages are displayed on the display means in the message display, namely an oldest message and a most recent message, wherein further messages that are located between the oldest message and the most recent message can be displayed on the display means in a scrollable manner between the oldest message and the most recent message, and o a first event display having a main section and a first edge section that is different from the main section and is arranged in a lower section of the display area, wherein the main section is larger than the first edge section and the first edge section occupies less than 30% of a height of the display area,wherein the first event display displays a first event characterizing the hazardous situation in the main section and displays the oldest message and the most recent message in the first marginal section of the display means, wherein the message displays are further called up by the operator when the operator taps the main section when the first event display is displayed, and the control unit is configured, upon receipt of the first signal, to control the display means such that the first event display is displayed instead of the idle display and / or the message display.

[0010] The hazard detector is designed to detect a hazardous situation. The hazard detector can, for example, be a fire detector, preferably designed as a smoke detector or a flame detector.

[0011] The hazard detector, which in particular is not part of the control unit, is preferably designed to generate a first signal characterizing the hazardous situation. The control unit is configured accordingly to receive the first signal. The control unit can comprise suitable receiving means for this purpose.

[0012] The control unit comprises the user interface with the display means. The display means can display the idle display and / or the message display as well as the first event display. The idle display can be a screen saver, for example. The control unit is configured to display the idle display if no user interaction has occurred for a predetermined period of time. Furthermore, the control unit can be configured to display the idle display if the first event display has been displayed for a predetermined period of time, for example, 1 hour.

[0013] The message display can show several individual messages. The content of a message can be, for example, a fault, a fire, or a fire pre-alarm. The control unit is configured such that an oldest message and a most recent message are always displayed. In addition, further messages can be displayed between the oldest and most recent message. The control unit is further configured such that the display of the further messages can be changed by scrolling, thus allowing a large number of further messages to be displayed between the most recent and oldest message. The messages are preferably arranged chronologically from the oldest message, which is arranged, for example, in an upper area, to the most recent message, which is arranged, for example, in a lower area.

[0014] When a hazard detector detects a hazardous situation, it preferably generates the first signal characterizing the hazardous situation. The control unit is configured to display the first event indicator upon receipt of the first signal. The first event indicator displays the first event in the main section so that a user of the control unit can immediately recognize the first event. The first event can, for example, be a fire in a monitoring area monitored by the hazard detector.

[0015] As soon as the first event display is shown by the display means, the oldest message and the most recent message are displayed in a first border section. The first border section is different from the main section. The border section is characterized in particular by the fact that it occupies a smaller portion of the display area of ​​the display means than the main section.

[0016] The border section can be arranged in an edge area of ​​the display. For example, the first border section can be arranged on the left, right, top, or bottom. The first event display thus includes the display of the first event as well as the oldest and most recent message.

[0017] A lockout period can be specified for the display of the first event log in the main section. During the lockout period, the first event log remains active, and no idle or message display is shown. For example, the lockout period can be 1 hour.

[0018] The invention is based on the finding that rapid detection of a danger alert by a user of a control unit of a danger alarm control center can be important for the efficiency of a danger alarm system. In particular, rapid detection of a dangerous situation can increase the speed of the user's response and thus reduce or prevent personal injury and / or property damage. For example, the user can make the decision to alert the fire department more quickly, for example, by activating the first action mechanism explained in more detail below.

[0019] According to the invention, the user interface is designed as a touch-sensitive input and output screen.

[0020] The touch-sensitive input and output screen can be designed, for example, as a so-called touchscreen. Such screens have the advantage that the control unit has no or fewer buttons, which are potentially susceptible to wear. The output screen is to be understood as the output device. The input screen can be designed to overlap the output screen. A touch-sensitive input and output screen also saves space.

[0021] According to the invention, the control unit comprises a message actuating means, wherein upon actuation of the message actuating means, the display means is controlled by the control unit such that the message display is displayed instead of the first event display, wherein the message actuating means is arranged on the input and output screen in the main section.

[0022] The message actuation means is formed by the touch-sensitive input and output screen.

[0023] By activating the message activation means, a user of the control unit can move from the first event display to the message display. This allows the user to move from the first event display, which is particularly intuitive but preferably has a low information density, to the message display with detailed information.

[0024] In a preferred development of the control unit, it is provided that it comprises a first action means, wherein the control unit is set up to generate and preferably send an alarm signal, in particular for alerting a fire brigade, upon actuation of the first action means, and / or a second action means, wherein the control unit is set up to extend a predetermined waiting time by a predetermined reconnaissance time upon actuation of the second action means, and / or a third action means, wherein the control unit is set up to inhibit generation and / or sending of an alarm signal upon actuation of the third action means.

[0025] The action means can, for example, be arranged as touch- and / or pressure-sensitive buttons on the user interface. These can, for example, be part of the touch-sensitive input and output screen. The predetermined waiting time can, for example, be the time that should elapse between the receipt of the first signal at the control unit and the transmission of an alarm signal, for example, to alert a fire department. If no interaction occurs during this time, the alarm signal is sent and the first event display remains displayed.

[0026] If a user interacts with the control unit during the waiting time, they can activate the first action means, the second action means, or the third action means. If the user activates the second action means, the waiting time is extended by the predetermined exploration time. The predetermined exploration time can be used by the user, for example, to verify the hazardous situation, for example, by approaching the corresponding hazard detector and assessing the hazardous situation. The waiting time can be 30 seconds, for example. The waiting time and the predetermined exploration time together can be a maximum of 10 minutes, for example.

[0027] If the user reaches the control unit before the waiting time has elapsed and believes that an alarm signal should be generated, they can immediately activate the first action means to send the alarm signal. Furthermore, the user can also activate the third action means by inhibiting the generation and / or transmission of an alarm signal.

[0028] In a further preferred development of the control unit, it is provided that the first action means, the second action means and / or the third action means are arranged on the input and output screen, preferably in a second edge section.

[0029] The first edge portion is preferably different from the second edge portion.

[0030] The first edge section is formed in a lower area, for example, as a line.

[0031] The second border section can, for example, be represented as a column in a left-hand section of the display means. In particular, it is preferred that the first border section and the second border section do not overlap, thus ensuring a clear assignment of the action means to the function to be controlled thereby.

[0032] Furthermore, it is preferred that the control unit is configured to generate and preferably transmit the alarm signal, in particular for alerting a fire department, after a predetermined waiting period following receipt of the first signal. Preferably, the control unit is configured to display an alarm signal on the display means. The alarm signal display indicates to a user of the control unit that the fire department has already been called.

[0033] According to a further preferred embodiment of the control unit, it is configured to receive an all-clear signal and, upon receipt of the all-clear signal, to control the display means such that the idle display and / or the message display is displayed instead of the event display.

[0034] The all-clear signal can be used in particular for acknowledgment and / or resetting.

[0035] According to a further preferred embodiment of the control unit, it is provided that the display means is configured to display a second event display indicating a second event in the main section, and / or to display a third event display indicating a third event in the main section, wherein the oldest message and the most recent message are displayed in the first marginal section, and the control unit is configured to receive and / or generate a second signal characterizing a fault, in particular a fault signal, and upon receipt of the second signal, to control the display means such that the second event display is displayed instead of the idle display and / or the message display, and / or to receive and / or generate a third signal characterizing an alarm, in particular an alarm signal, and upon receipt of the third signal, to control the display means such thatthat the third event display is displayed instead of the idle display and / or the message display.

[0036] The second event could be a fault, for example. If the second event is displayed in the main section, the oldest message and the most recent message are displayed in the first margin section. The third event could be an alarm. If the third event is displayed in the main section, the most recent and oldest messages can be displayed, similar to the first or second event display.

[0037] Alternatively, in the second and / or third event display, only the most recent message can be displayed as the only message in the first margin section.

[0038] As soon as a fault occurs and the control unit receives or generates the second signal, the display device is controlled to display the second event indicator. Similarly, in the event of an alarm, the third signal is generated or received, and upon receipt of the third signal, the display device is controlled to display the third event indicator.

[0039] In a further preferred embodiment, it is provided that the oldest message and / or the most recent message and / or the further messages have a bar-shaped representation, wherein the bar-shaped representation preferably extends from a left edge of the display means to a right edge of the display means.

[0040] Furthermore, it may be preferred that the display means has a display area and the main portion occupies more than 60%, more than 70%, more than 80% or more than 90% of the size of the display area.

[0041] Furthermore, the first edge portion is arranged in a lower portion of the display area and preferably borders a lower edge of the display area and occupies less than 30%, preferably less than 20%, or less than 10% of a height of the display area. Furthermore, it is preferred that the second edge portion is arranged in a left portion of the display area and preferably borders a left edge of the display area and preferably occupies less than 30%, less than 20%, less than 10%, or less than 5% of a width of the display area.

[0042] In addition, the control unit is configured to display the idle indicator on the display after a predefined period of inactivity. The inactivity period can be, for example, 1 hour in the case of a fire alarm.

[0043] According to a further aspect, the object mentioned at the outset is achieved by a hazard alarm control center, for example an intrusion, fire alarm and / or extinguishing control center, comprising a control unit according to one of the embodiments described above.

[0044] According to a further aspect, the object mentioned at the outset is achieved by a hazard alarm system, preferably a fire alarm system, with a hazard alarm control center, for example a burglar alarm, fire alarm and / or extinguishing control center, the hazard alarm system comprising a hazard alarm for detecting a dangerous situation, for example a fire, a control unit according to claim 1 which is coupled to the hazard alarm by signal technology and is set up to receive a first signal characterizing the dangerous situation from the hazard alarm.

[0045] According to a further aspect, the object mentioned at the outset is achieved by a method for operating a hazard alarm control center, for example an intrusion, fire alarm and / or extinguishing control center, comprising the steps according to claim 13.

[0046] The method and its possible further developments have features or process steps that make them particularly suitable for use in a control unit, a hazard alarm control panel, and a hazard alarm system, as well as their respective further developments. For further advantages, design variants, and implementation details of these additional aspects and their possible further developments, please refer to the above description of the corresponding features and further developments of the control unit.

[0047] Preferred embodiments are explained using the accompanying figures. They show: Figure 1: a schematic representation of a hazard detection system; Figure 2: the hazard detection system from Figure 1 with a first event display; Figure 3: the hazard warning system from Figure 1 with a second event display; Figure 4: the hazard alarm system from Figure 1 with a third event display; Figure 5: the hazard alarm system from Figure 1 with a message display; and Figure 6: a schematic method for operating a hazard alarm control center.

[0048] In the figures, identical or essentially functionally identical or similar elements are designated by the same reference numerals.

[0049] Figure 1shows a schematic representation of a hazard detection system. The hazard detection system comprises a hazard detection control panel 1 with a control unit 10 and a hazard detector 40. The hazard detector 40 can be, for example, a fire gas or smoke detector, heat detector, smoke detector, flame detector, or spark detector. The hazard detector 40 is arranged in a monitoring area 30. Preferably, the monitoring area 30 is spatially separate from the location where the control unit 10 is arranged.

[0050] The control unit 10 is part of the alarm control panel 1, which is preferably designed as an intrusion, fire alarm, and / or extinguishing control panel. The control unit 10 comprises a display 20. The display 20 is designed to display information. The display 20 can, for example, be designed as a touch-sensitive input and output screen.

[0051] The display means 20 can display a wide variety of information, for example the Figure 1 The idle display 100 shown here can be, for example, a screen saver. In particular, the idle display 100 is displayed by the display means 20 if no interaction with an operator of the alarm control panel 1 and / or the control unit 10 has occurred for a predetermined period of time.

[0052] The hazard detector 40 is designed to detect a hazardous situation. The control unit is configured to receive a first signal from the hazard detector 40 that characterizes the hazardous situation. For this purpose, the hazard detector system has a coupling interface 12. The coupling interface 12 couples the hazard detector 40 to the control unit 10.

[0053] Figure 2 shows the hazard warning system Figure 1with a first event display 200. In the state shown here, a dangerous situation was detected by the hazard detector 40, and a first signal characterizing this dangerous situation was received by the control unit 10. Upon receipt of this first signal, the control unit 10 is configured to control the display means 20 such that the first event display 200 is displayed instead of the idle display 100. The same applies if the message display explained in more detail below is displayed on the display means 20. The first event display 200 displays a first event in a main section 210. Furthermore, the first event display displays an oldest message 222 and a most recent message 224 in a first border section 220.

[0054] The main portion 210 is preferably the largest area displayed on the display means 20. The first edge portion 220 is arranged in an area adjacent to a bottom edge and a right edge of the display means 20.

The second edge portion 230 comprises a first action means 232, a second action means 234, and a third action means 236. Upon actuation of the first action means 232, an alarm signal is generated and transmitted, wherein the alarm signal can be designed to alert a fire department. Upon actuation of the second action means 234 by an operator, a predetermined waiting time is extended by a predetermined investigation time. The waiting time is, for example, the time that elapses between the receipt of the first signal to the control unit 10 and the transmission of an alarm signal, for example to a fire department. This time can be, for example, 30 seconds.The predetermined reconnaissance time then extends this waiting time so that, for example, an operator can verify the detected hazardous situation.

[0056] The third action means 236 preferably inhibits the generation and / or transmission of an alarm signal. The third action means can be used, for example, by an operator in the event of a false alarm to prevent a fire department from being alerted.

[0057] Figure 3 shows the hazard warning system Figure 1 with a second event display 300. The hazard alarm system shown comprises the hazard alarm control panel 1 with a control unit 10 and a coupling interface 12, wherein the coupling interface 12 couples the control unit 10 to the hazard alarm device 40, wherein the hazard alarm device 40 can monitor the monitoring area 30 and detect hazardous situations.

[0058] A second event display 300 is shown on the display means 20 of the control unit 10. The second event display 300 also includes a main section 310 and a first peripheral section 320, but without the second peripheral section described above. The display means 20 here shows a second event display 300, which displays a second event in the main section 310 and a most recent message 324 and an oldest message 322 in the first peripheral section 320. The second event in this case is a fault.

[0059] Figure 4 shows the hazard warning system Figure 1 with a third event display 400.

A most recent message 424 and an oldest message 422 are displayed in the first peripheral section 420.

[0060] Alternatively, only the most recent messages 224, 324 or 424 can be displayed in the respective first border section 220, 320, 420 of the first event display 200, the second event display 300 and / or the third event display 400.

[0061] Figure 5 shows the hazard warning system Figure 1 with a message display of 500.

[0062] The display means 20 of the control unit 10 here displays the message display 500. The message display 500 displays a plurality of messages in full screen. The message display 500 can be called up by an operator by tapping the main section 210, 310, 410 of the event displays 200, 300, 400.

[0063] Furthermore, the message display 500 can be called up by an operator by tapping the screen or the display means 20 while the idle display 100 is displayed. The message display 500 displays a number of messages.

[0064] Figure 6 shows a schematic method for operating a hazard alarm control panel. In step 1001, the idle display 100 and / or message display 500 is displayed by means of the display means 20, wherein an oldest message 222 and a most recent message 224 are displayed, and further messages can be displayed between the oldest message 222 and the most recent message 224. According to the invention, the messages arranged between the oldest message 222 and the most recent message 224 are arranged in a scrollable manner. This means that a suitable scrolling means on the control unit 10 enables the display of a plurality of messages. Alternatively, an idle display 100 can be displayed in step 1001.

[0065] In step 1002, a dangerous situation is detected, preferably by a danger detector 40. Furthermore, in step 1002, a first signal characterizing this dangerous situation is generated. This first signal is preferably generated by the danger detector 40.

[0066] This first signal is received in step 1003. It is preferred that the first signal be received by the control unit 10. Furthermore, a coupling interface 12 can be arranged between the control unit 10 and the hazard detector 40.

[0067] In step 1004, a first event is displayed in the first main section 210 of the display means 20, and the oldest message 222 and the most recent message 224 are displayed in a first border section 220.

[0068] The present invention enables a reduction in response time to events. Displaying the first event indicator 200 in the main section 210 and moving the messages 222, 224 to the first peripheral section 220 allows an operator to immediately recognize the type of event. The operator can thus initiate the necessary steps much more quickly, thus avoiding or at least reducing personal injury and / or property damage. REFERENCE SYMBOL
