[0002] DESCRIPTION

[0003] The present disclosure relates to a method and / or a device for providing a communication signal in an automation system comprising at least one machine component. Additionally or alternatively, a system with a device according to the disclosure and the use of the device according to the disclosure are provided. Additionally or alternatively, a computer program is provided which includes instructions that, when executed by a computer, cause the computer to execute at least part of the disclosed method.

[0004] STATE OF THE ART

[0005] The monitoring and remote maintenance of machine tools and / or automation systems is of great importance in industry. Existing remote service solutions for monitoring machine tools and / or automation systems often rely on live streams that require active user observation to detect machine states, process cycles, and / or downtimes. This manual monitoring is time-consuming and demands constant user attention, leading to inefficient resource utilization and the risk of overlooking critical events.

[0006] A known problem with these solutions is the lack of sufficient integration of acoustic signals that could indicate important machine events. Current systems mostly rely on visual transmission via live streams and neglect the possibility of using acoustic warning signals to specifically target user attention. This can lead to important malfunctions and / or changes in the condition of machine components and / or automation systems being overlooked, especially when monitoring is remote and users need to monitor multiple machines simultaneously.

[0007] In light of this prior art, one objective of the present disclosure may be to specify a method and a device for providing a communication signal in an automation system comprising at least one machine component, each of which is suitable to enrich the prior art.

[0008] The problem is solved by the features of the independent claims. The dependent and subordinate claims each contain optional further developments of the disclosure. Accordingly, the problem is solved by a method according to claim 1. The method provides a communication signal in an automation system. The automation system comprises at least one machine component.

[0009] For the purposes of this disclosure, an automation system is a technical system consisting of various interconnected machine components and / or control units that can be used to automate manufacturing or production processes. The automation system includes various types of machines, such as robots, conveyor belts, sensors, and / or actuators, which can be coordinated, controlled, and / or monitored by a central control unit to ensure the precise and efficient execution of tasks.

[0010] A technical advantage of such an automation system can be an increase in production capacity and an improvement in product quality, as well as contributing to the reduction of human errors and operating costs by performing repetitive or complex tasks independently.

[0011] For the purposes of this disclosure, a machine component is a single, functional element within a machine or system, in particular an automation system, that can perform specific tasks and contributes to the overall function of the automation system. The machine component includes mechanical, electrical, hydraulic, and / or pneumatic components, such as motors, gears, sensors, actuators, transport / conveyor units, controllers, and / or connecting elements. Machine components can be modular and operate individually or in combination with other components to provide complex motion sequences, control processes, and / or other mechanical functions within an automation system.

[0012] Machine components in an automation system offer the advantage of modular and flexible system design, facilitating system adaptations and expansions. Integrating specialized machine components can increase the efficiency and precision of the entire system, as each component can be optimally designed for a specific function. This leads to improved overall performance, reduced downtime, and / or faster fault diagnosis and resolution, which can enhance the productivity and reliability of the automation system.

[0013] The procedure comprises several steps. In a first step, at least one interference signal from at least one machine component of the automation system is detected.

[0014] For the purposes of this disclosure, "monitoring" can include the detection and identification of deviations or anomalies in the operation of the machine component through the use of sensors. The sensors monitor physical quantities such as temperature, vibration, noise, and / or electrical signals of the machine component within the automation system. Furthermore, monitoring can include the collection and recording of data on the condition of the machine component in real time or over a defined period, indicating an impending or actual fault. It can also include the interpretation and analysis of the collected data by specialized software or algorithms to determine the nature and cause of the fault signal and to provide appropriate measures for troubleshooting or maintenance.

[0015] For the purposes of this disclosure, a disturbance signal can include various types of deviations or anomalies in the machine component of the automation system that indicate a malfunction or undesirable condition in the machine component and / or the automation system. A disturbance signal can include mechanical deviations such as unusual vibrations or noises that may indicate wear or damage. The disturbance signal can be an electrical disturbance signal showing deviations in voltage or current levels that indicate power supply problems or short circuits. The disturbance signal can be a thermal disturbance signal and include elevated or irregular temperatures that indicate overheating or cooling problems.Additionally, process parameters, such as deviations from target values ​​for pressure, flow rate, or velocity, can be detected as disturbance signals indicating a malfunction of the machine component. These deviations can represent exceeding or falling below a defined permissible tolerance range. Alarm thresholds can also be defined as disturbance signals based on a level of criticality reached. Furthermore, a disturbance signal can also consist of error codes detected and reported by the control software, which indicate specific problems or fault conditions of the machine component.

[0016] The technical advantage of detecting a fault signal lies in the early and precise identification of errors or deviations in the operation of a machine component. By detecting anomalies, problems can be identified and analyzed immediately, enabling a rapid and targeted response. This reduces unforeseen downtime and prevents costly damage, as maintenance measures can be initiated in a timely manner.

[0017] In a further step, a selected warning signal is assigned to a communication signal based on the detected interference signal.

[0018] For the purposes of this disclosure, assignment means the mapping of a specific warning signal to a communication signal based on a detected disturbance signal. This includes selecting and linking the appropriate warning signal, reflecting a specific anomaly or fault condition, with the communication signal that is then transmitted. The assignment includes a mapping comprising at least one lookup table and / or at least one multidimensional mapping table. Further parameters, such as speech output and units of measurement according to international usage, are taken into account. These parameters vary accordingly and include information such as the metric system, country-specific language, machine type, and / or user schema configuration.Furthermore, assignment in the state of the art includes multiplexing technology, audio encoding, in particular Advanced Audio Coding (AAC), a container format, in particular MP4, MKV, and sound overlay software.

[0019] By assigning a selected warning signal to a communication signal, relevant information about the condition of the automation system's machine component can be transmitted in a targeted and precise manner. This assignment also ensures that the communication signal contains the necessary information (details) for troubleshooting, enabling users to react quickly and efficiently to malfunctions. This optimizes maintenance and repair processes, minimizes downtime, and increases the operational readiness and reliability of the entire automation system. Furthermore, this assignment facilitates the monitoring of remote solutions, as events can be specifically targeted to a user via audio output.

[0020] For the purposes of this disclosure, the term "selected" refers to the targeted selection of a specific warning signal from a predefined set of possible warning signals. This selection is based on the detected fault signal and its analysis to ensure that the warning signal conveys the most relevant information about the state and urgency of the fault. The selection process ensures that the chosen warning signal is best suited to indicate the nature and severity of the fault and to initiate the necessary actions. Furthermore, the targeted selection is achieved through a multidimensional mapping table for situationally appropriate mapping, such as considering dimensions and parameters other than just the fault signal itself.This includes international requirements, site-specific, user-specific and machine-specific parameters and / or user-adapted parameters, such as language and / or the urgency of a currently processed order by the automation system.

[0021] For the purposes of this disclosure, a warning signal can be a signal designed to indicate an abnormal condition and / or malfunction within the automation system. It can take various forms, such as acoustic tones, in particular sirens or voice announcements; visual indicators, in particular flashing lights or displays on screens and monitors; or textual messages. The warning signal informs the users or the monitoring system of the nature, location, and / or urgency of the detected disturbance signal in order to enable a rapid and appropriate response.

[0022] The selected warning signal allows for a tailored approach to the specific conditions of the detected fault signal. Choosing the most appropriate warning signal ensures that users can clearly and immediately understand the criticality, nature, severity, and / or urgency of the problem and classify faults. This enables a faster and more effective response to faults, which can improve the safety, efficiency, and continuous operation of the automation system and machine components. Furthermore, operation can be simplified when error messages are communicated directly to users via audio output, which is particularly advantageous in noisy environments where headphones must be worn.Enriching the live stream by using the previously unused audio channel in the video transmission process leads to increased convenience for remote monitoring and makes optimal use of the existing infrastructure.

[0023] For the purposes of this disclosure, a communication signal is a message, command, and / or information transmitted over a network or system and comprising multiple channels, including audio and video channels, to transmit different types of information simultaneously. The communication signal is transmitted as an electrical signal over a suitable communication medium. It includes both digital and analog information in various formats, such as h.264 for video and Advanced Audio Coding (AAC) for audio. The channels are synchronized to ensure that audio and video content is transmitted simultaneously and coherently. Communication signals are modulated to maximize transmission efficiency and optimize bandwidth utilization. They are processed in real time and transmitted over various networks, including wired and wireless connections.Security mechanisms such as encryption are implemented to ensure the confidentiality and integrity of the information. Error correction mechanisms are integrated to guarantee the accuracy of the transmitted data. The communication signal can also be transmitted via fiber optic cables. For this, the optical signals are converted into electrical signals at the endpoints of the fiber optic transmission. This conversion is performed by transceivers, which convert optical signals to electrical signals and vice versa.

[0024] A technical advantage can arise in that the communication signal provides multiple channels, including audio and video channels, thus allowing optimal use of the available bandwidth.

[0025] In a further step, the communication signal is provided.

[0026] For the purposes of this disclosure, "providing" means making the communication signal accessible and transmitting it to one or more target components or systems within or outside the automation system. This includes outputting the signal in a form that can be received and used by the intended recipients, such as monitoring systems or users. Providing includes both the real-time transmission and use or output of the communication signal, as well as its storage for later analysis or use.

[0027] A technical advantage of providing a communication signal lies in the efficient and targeted transmission of relevant information to the intended recipients, both inside and outside the automation system. This enables a rapid and effective response to malfunctions by immediately informing users about the status and any problems with machine components within the automation system or the automation system itself. Real-time transmission of the communication signal facilitates monitoring of the automation system, particularly in remote solutions, as events can be specifically targeted to users via audio output.Furthermore, the existing infrastructure is used optimally by integrating the warning signal as an audio track in the video signal, which leads to increased convenience for remote monitoring and maximizes the use of unused but available bandwidth.

[0028] The method described above offers several advantages. It facilitates the monitoring of remote solutions, as events can be specifically targeted to a user's attention via audio output. Furthermore, operation can be simplified if error messages are provided directly to machine operators as spoken words. This can also be used on-site, for example, when hearing protection, such as headphones, must be worn due to high noise levels. Additionally, it is advantageous to enrich the live video stream with the warning signal as audio, since in current state-of-the-art methods, an audio track remains unused in the video transmission, thus not fully utilizing the available bandwidth. Finally, remote monitoring becomes more efficient and cost-effective.This can be achieved by using existing infrastructure, whereby an audio track can be used effectively in the video signal.

[0029] Possible further developments of the procedure described above are explained in detail below.

[0030] The communication signal may include a combined video and audio transmission. Furthermore, the communication signal may utilize different channels.

[0031] For the purposes of this disclosure, a channel and / or a plurality of channels is a specific transmission path within the communication signal that can be used for the separate transmission of different types of data. A channel is configured for different signal types, such as audio or video, and enables the parallel and independent transmission of these signals within a common communication signal. In particular, a channel that transmits audio and / or a warning signal is an audio track.

[0032] The technical advantage of using channels within a communication signal enables the parallel and independent transmission of audio and video data, ensuring clear and interference-free information delivery. This results in a coherent and timely presentation of the transmitted information, as the channels enable specific functions such as real-time synchronization of audio and video data. This facilitates the monitoring of remote solutions, as events can be specifically targeted to users' attention via audio output. Furthermore, it allows for easier operation when error messages reach users directly via audio output as spoken words, which is particularly useful in noisy environments when headphones are required.The sensible use of the audio track in the video signal optimizes the existing infrastructure and leads to increased convenience for remote monitoring by effectively utilizing previously unused resources.

[0033] Furthermore, it may be provided that the assignment of the selected warning signal includes the transmission of the warning signal via an audio channel of the communication signal.

[0034] For the purposes of this disclosure, the audio channel of the communication signal refers to a dedicated data transmission path within the communication signal specifically intended for the transmission of audio data. The audio channel is part of a comprehensive communication signal that may contain both video and audio data, and enables the synchronous transmission of audio content, such as warning signals, with the visual information of the video signal. In an h.264-based video signal, the audio channel can be integrated into a container format such as MP4 or MPEG-TS, with the audio channel carrying audio data such as speech, music, or, in this case, a warning signal, synchronized with the visual content of the video. This enables a coherent presentation of audio and video that can be simultaneously received and interpreted by the user.

[0035] This enables targeted and clear communication of machine states and malfunctions. Transmitting the warning signal via a dedicated audio channel ensures that critical acoustic warnings are relayed to users in real time, drawing attention to critical events and allowing for a rapid response. Monitoring and control of remote solutions can be improved, as acoustic signals specifically target personnel attention. Furthermore, existing infrastructure is used efficiently by integrating the audio track into the video signal, thus avoiding the need for additional transmission infrastructure.

[0036] Furthermore, it may be provided that the assignment of the selected warning signal is time-synchronized, in particular synchronized in real time.

[0037] The technical advantage of time-synchronized assignment lies in the precise and immediate communication of critical information. Real-time synchronization of the warning signal with the communication signal ensures that audible warnings are transmitted at the exact moment the corresponding event occurs. This allows users to immediately and accurately associate the warning with the observed event in the video stream, significantly reducing response time to malfunctions. Real-time synchronization thus increases the efficiency and reliability of monitoring and troubleshooting, as users are instantly informed of critical events and can initiate appropriate measures without delay. This leads to improved operational reliability and reduced downtime, as problems can be detected and resolved more quickly.

[0038] It may be provided that the audio channel comprises at least two mono channels, wherein a first mono channel comprises a first signal in the audible range for humans and a second mono channel comprises a second signal as user data for interpretation in the form of a suitable hardware / software decoder.

[0039] For the purposes of this disclosure, a mono channel is understood to be a single channel provided on a first output unit and optionally also on a second output unit. The output unit may comprise a loudspeaker and / or a screen. In particular, the first output unit may be a loudspeaker and the second output unit may be a screen.

[0040] Furthermore, two mono channels create a stereo audio signal. These can be output to separate and independent devices. These two mono channels are independent and can contain different information.

[0041] The technical advantage is that this allows for two different signals, for example in the audible range for humans, and another signal as user data for interpretation in the form of a suitable hardware / software decoder.

[0042] The technical advantage of at least two mono channels in the audio channel lies in the increased flexibility and functionality in the transmission and processing of audio signals. By providing two independent mono channels, different information can be transmitted simultaneously, making it possible to send various signals at the same time. For example, one mono channel can be used to output an audible warning signal that is directly perceived by the user, while the second mono channel can transmit additional user data, primarily, but not exclusively, in the inaudible frequency range, intended for interpretation by hardware or software decoding.

[0043] This not only enables the simultaneous transmission of acoustic warning signals and additional information data, but also contributes to improved utilization of existing infrastructure by integrating the warning signal effectively into the audio channel of the communication signal. Furthermore, it facilitates the monitoring of remote solutions, as acoustic signals can specifically draw users' attention to critical events. The use of two mono channels in a stereo configuration thus offers greater precision and efficiency in signal transmission and processing, resulting in overall improved monitoring and control of the automation system.

[0044] It may be provided that the communication signal is encoded in a standardized video format. For the purposes of this disclosure, a standardized video format is a defined set of specifications and rules for encoding and compressing video data, enabling consistent and efficient storage and transmission of video content. Specifically, the h.264 video format is specified. The h.264 video format, also known as Advanced Video Coding (AVC), offers a high compression rate and video quality. It can be used in applications such as streaming, video recording, and video transmission because it enables efficient bandwidth utilization and offers compatibility with many devices and platforms.

[0045] For the purposes of this disclosure, encoding in the context of video data means providing video content in a standardized format that enables efficient storage, transmission, and playback. This involves applying algorithms to compress the video data in order to reduce file size while preserving video quality. Encoding combines and synchronizes both video and audio signals, such as the warning signal in the audio channel, in a format like h.264 so that they can be transmitted simultaneously and coherently. This ensures that audiovisual content is delivered efficiently and in high quality across various networks and platforms.

[0046] The standardized video format, particularly h.264, and the encoding of the communication signal offer several technical advantages. The high compression rate of h.264 enables efficient bandwidth utilization, which is especially beneficial for transmitting live streams over the internet or in networks with limited capacity. Integrating the warning signal into the audio channel and transmitting it in time-synchronized fashion ensures that critical audible warnings are synchronized with the video content in real time. This results in clear and precise communication of machine states and malfunctions, improves monitoring and response capabilities, and optimizes the use of the existing communication signal bandwidth without requiring additional transmission paths. Furthermore, a standard video player can be used, as h.264 is a video standard with an integrated audio track.

[0047] The interference signal may include machine events that are based on digital sensor data from the machine component. For the purposes of this disclosure, machine events are specific states or incidents that can occur during the operation of the automation system and affect its normal function. These events include both regular operating states and abnormal states, such as start-up and stop-down processes, production cycles, maintenance requests, error messages, or malfunctions. Machine events provide information about the operation and condition of the automation system and are crucial for monitoring, controlling, and maintaining the machine components of the automation system. Sensor data, as defined in this disclosure, are the measured values ​​and / or information acquired by sensors that monitor and measure certain physical or chemical properties.This data can take various forms, including temperature, pressure, vibration, humidity, light intensity, or position. Sensors convert the measured physical quantities into electrical signals, which are then processed and analyzed.

[0048] Digital sensor data, as defined in this disclosure, are the digitized measured values ​​acquired by sensors and converted into a form understandable to digital systems. Instead of using continuous, analog signals, the measured values ​​are converted into discrete numbers, i.e., digitized, which can be processed by computers and other digital devices. During digitization, compression is possible, including the application of filters such as low-pass, median, and moving average filters. This digitization enables precise, fast, and efficient processing, storage, and transmission of the sensor data. Digital sensor data offer the advantage of easy integration into modern automation systems and enable accurate and reliable monitoring and control of machine components. Capturing machine events based on digital sensor data can offer several technical advantages.Using digital sensor data ensures high accuracy and reliability in monitoring and analyzing machine conditions. Digital data is easy to process and analyze in real time, enabling rapid response to malfunctions and optimization of machine performance. Integrating sensor data into the communication signal can improve precise diagnostics and troubleshooting capabilities, thereby increasing the overall availability and efficiency of the automation system. Furthermore, it can enhance the perceived effectiveness of error messages, as they are delivered directly to users via audio output, which is particularly beneficial in noisy environments where headphones are required. This integration improves the utilization of existing infrastructure and increases the convenience of remote monitoring by effectively utilizing the audio track within the video signal.assigns the warning signal to the audio channel of the communication signal.

[0049] A warning signal may be provided, comprising at least detected warning tones. For the purposes of this disclosure, detected warning tones are acoustic signals recorded directly from the machine component or from the environment. These tones may be used to indicate specific conditions or events generated by natural noises or operating noises of the machine.

[0050] The technical advantage of the captured warning tones lies in the direct and unadulterated transmission of acoustic signals representing specific operating states or anomalies of the machine component and / or automation system. This facilitates the identification and classification of malfunctions, as the natural sounds of the machine component / automation system are familiar to users. This can simplify the monitoring of remote solutions, as users can react specifically to familiar sounds, leading to faster response and troubleshooting.

[0051] Furthermore, the warning signal may include synthetically generated and / or frequency-modulated warning tones. For the purposes of this disclosure, synthetically generated warning tones are artificially generated acoustic signals that can be produced by electronic devices or software. In the case of frequency-modulated warning tones, the frequency of the tone is varied to signal different meanings or levels of urgency.

[0052] Synthetically generated and frequency-modulated warning tones offer the advantage of producing clear and easily distinguishable signals for various types of malfunctions or operating conditions. These tones can be specifically tailored to maximize user attention, even in noisy environments or when wearing headphones. The flexibility in tone design allows for the meaningful enrichment of the communication signal in the audio channel during video transmission, as unused audio tracks are effectively utilized. This leads to increased efficiency and convenience for remote monitoring and makes optimal use of existing infrastructure.

[0053] Furthermore, the warning signal may include voice messages. For the purposes of this disclosure, voice messages are understood to be acoustic warning signals transmitted as spoken words or sentences. These may be generated by speech synthesis (text-to-speech) or by pre-recorded voice recordings to communicate specific information or instructions.

[0054] Voice messages offer the technical advantage of clear and understandable communication of complex information and instructions directly to users. This simplifies the operation of the automation system, especially when immediate and specific instructions are required. Voice messages are useful in noisy environments because they can be easily understood through headphones or speakers. Integrating voice messages into the communication signal contributes to better utilization of existing infrastructure by making effective use of the audio track of the video transmission and drawing users' attention to critical events.

[0055] It may be provided that the warning signal comprises a combination of an acoustic component perceptible to the user and sensor data from at least one machine component of the automation system. For the purposes of this disclosure, a combination of the warning signal means an acoustic component perceptible to the user and an inaudible component into which additional sensor data from the machine component of the automation system are embedded by means of modulation techniques, in particular frequency and / or amplitude modulation based on a carrier signal. The modulation makes it possible to integrate sensor data such as temperature, pressure, vibration, humidity, or electrical signals or other operational parameters into the warning signal without this data being directly audible to the user or distorting and / or rendering the signal unusable. The inaudible components of the warning signal can, for example, be...The inaudible components of the warning signal are embedded in a frequency range above the human hearing threshold, particularly above 25 kHz. These inaudible components can be demodulated by appropriate software and displayed as additional information, thus creating a combined warning signal.

[0056] For the purposes of this disclosure, a combined warning signal is an acoustic or visual signal based on a combination of sensor data acquired by a sensor from at least one machine component of the automation system or from the automation system itself. This sensor data can include various parameters such as temperature, pressure, vibration, humidity, or electrical signals. The combined warning signal integrates this diverse data to provide a comprehensive overview of the machine component's condition and to precisely identify and / or communicate specific faults or operating states. This enables efficient information transmission, as additional sensor data can be transmitted via the same audio channel as the communication signal. Thus, the existing infrastructure is optimally utilized, since the warning signal is integrated into the communication signal's audio channel.This expanded functionality provides an additional source of information for fault diagnosis and monitoring of the automation system, as detailed sensor data is available in real time. At the same time, user-friendliness is maintained, since the user continues to be alerted by the audible warning signal, while the embedded sensor data can be accessed via software as needed. This solution also offers increased flexibility and adaptability of the system, as various sensor data can be integrated within the inaudible range of the warning signal, allowing for individual customization to specific monitoring requirements. Overall, this leads to improved efficiency and precision in monitoring and fault diagnosis.

[0057] Another technical advantage of integrating various sensor data into a combined warning signal is the increased precision and reliability of fault detection and monitoring of machine components, thus reducing the likelihood of false alarms. This allows for improved early detection of potential malfunctions, contributing to predictive maintenance and potentially extending the service life of machine components. Furthermore, utilizing existing sensor data maximizes the efficiency of the existing infrastructure, as the full bandwidth of the video transmission is utilized by the audio track in the communication signal. The combined warning signal enables targeted audio output, drawing personnel's attention to remote solutions and reducing response time to malfunctions.The comprehensive information provided by the combined warning signal simplifies machine operation and offers increased comfort, especially in noisy environments where headphones must be worn. Overall, the integration of sensor data improves the efficiency and convenience of remote monitoring by optimizing resource utilization and streamlining the monitoring of the entire automation system.

[0058] It may be possible to classify the warning signal according to its criticality. For the purposes of this disclosure, criticality may refer to the severity or importance of a fault or condition in the automation system. Criticality serves to classify and prioritize warning signals in order to indicate the urgency and nature of the required actions. Classifying criticality enables targeted and effective communication of different faults and operating conditions.

[0059] It may be provided that the warning signal is classified according to its criticality. The warning signal may include at least a minor fault. A minor fault may involve the output of an initial beep. For the purposes of this disclosure, minor faults are less serious deviations or malfunctions in the operation of the machine components that do not require immediate action and do not have a significant impact on the overall function of the automation system. These faults are signaled by an initial beep, which is simple and unobtrusive, to alert the user to the deviation without expecting or requiring immediate intervention.

[0060] It may be provided that the warning signal is classified according to its criticality. This may include at least one medium-level fault. The medium-level fault may involve the output of at least one second signal tone. The second signal tone may be different from the first signal tone. For the purposes of this disclosure, medium-level faults are malfunctions or deviations in the operation of the machine component(s) that, while serious, do not require immediate action. These faults may lead to reduced efficiency or restricted operation of the automation system if they cannot be rectified within a reasonable timeframe. Medium-level faults are signaled by a second signal tone that differs from the first signal tone (minor faults) and the third signal tone (major faults). This allows the urgency and severity of the problem to be appropriately represented and / or communicated.This allows for a finer gradation and differentiation of fault urgency, enabling more precise and efficient monitoring and maintenance of the automation system. The specific signaling of medium-level faults allows users to respond to malfunctions that do not require immediate, but still timely, resolution to ensure the smooth operation of the automation system. This facilitates the monitoring of remote solutions, as events can be specifically targeted to users' attention via audio output. Furthermore, the use of existing infrastructure is optimized by integrating the audio track into the video transmission of the communication signal, resulting in an enhanced live stream and improved convenience for remote monitoring.The operation of the automation system is improved, especially when error messages reach users directly via sound output as spoken words, which is also useful in noisy environments where headphones must be worn.

[0061] It may be provided that the warning signal is classified according to its criticality. This may include at least one serious fault, which involves the output of at least a third signal tone. The third signal tone may be different from the first and / or second signal tone. For the purposes of this disclosure, serious faults are defined as serious disturbances or malfunctions that require immediate attention and action, as they can significantly impair the operational capability of the automation system. These faults are signaled by a second signal tone that is clearly distinguishable from the first signal tone in order to communicate the urgency and the need for a rapid response.

[0062] The warning signal can be classified according to its criticality. Operating states can be defined, which in turn can include at least a start state, a pause state, a stop state, and / or an end state of a process of the machine component. The criticality and the operating states can each be indicated by a corresponding signal tone.

[0063] For the purposes of this disclosure, operating states encompass various phases of machine operation, such as start, pause, stop, and / or the end of a process. Each of these states is signaled by a specific tone that clearly indicates the current status of the machine component. These signals assist the user in monitoring the machine's operation and acting or reacting accordingly.

[0064] Classifying warning signals according to their criticality provides a clear distinction between minor, medium, and severe faults, as well as different operating states. This allows for more precise and effective communication of machine statuses. It enables a targeted and rapid response to critical malfunctions, while less urgent problems can be prioritized accordingly. Targeted audio output can facilitate the monitoring of remote solutions and increases the convenience and efficiency of remote monitoring. Furthermore, existing infrastructure can be optimally utilized by meaningfully integrating the warning signal as an audio track within the communication signal, thus enriching the video transmission.

[0065] Furthermore, the operating state of the automation system can be taken into account when selecting the warning tone, especially when a fault signal occurs. A fault signal that occurs during production operation can trigger a different warning signal than a fault signal detected during maintenance or diagnostic operation. This allows for situation-specific adaptation of the warning signals, reflecting the current operating mode of the machine component. This ensures that the user is informed with the appropriate warning signals for each operating state, thus improving responsiveness and efficiency in troubleshooting.

[0066] This enhancement can increase the flexibility and accuracy of monitoring systems by taking into account the specific requirements and conditions of different operating states. This not only facilitates the monitoring of remote solutions through targeted acoustic signals but also contributes to the optimized use of existing infrastructure by integrating the warning signal effectively into the audio channel of the communication signal. This further simplifies the operation of the automation system and adapts it to the respective operating situation, resulting in more efficient and precise monitoring overall.

[0067] It may be provided that the communication signal is supplied to an output unit in real time. For the purposes of this disclosure, an output unit is a device or system that receives, displays, and / or outputs the communication signal. This may be a screen, a loudspeaker, a monitor, or another device that serves to convert and / or display the received data in a form that is understandable and usable for the user. In the automation system, the output unit may be used to provide visual and / or audible warning signals as well as other relevant operating information. The output unit may also be physically separate from the automation system and be part of a monitoring system, e.g., a control center. The output unit may be configured as an operator terminal on the automation system.Alternatively, the output unit can be designed as a mobile output unit, encompassing handheld devices such as laptops, tablets, or PDAs. Furthermore, the output unit can include LCD displays and be configured as monitors in control centers.

[0068] Providing the communication signal in real time to an output unit can include immediately and precisely displaying and / or outputting information about the current status of machine components to the user. This can facilitate the monitoring and control of the system, especially in remote solutions, as acoustic and visual signals can specifically target the user's attention.

[0069] It may be provided that the communication signal is stored in a storage unit. For the purposes of this disclosure, a storage unit is a component or system that temporarily or permanently stores data. This can be a hard drive, flash memory, a cloud storage system, or a ring buffer. A ring buffer is a special cyclic storage area that continuously stores new data and overwrites older data once the memory is full. In the automation system, the storage unit is used to archive communication signals and / or sensor data, enabling subsequent analysis and monitoring. The storage unit can also be physically separate from the automation system and be part of a remote monitoring center.This allows the communication signal to be stored in a memory unit, enabling detailed analysis and fault diagnosis at a later time. The memory unit can be configured as a ring buffer, effectively managing temporary data and ensuring that up-to-date information is always available without overloading the memory. This combination leads to increased efficiency and reliability of the monitoring systems. Furthermore, it facilitates the operation of the automation system, especially when error messages and operating states are communicated directly to users via audio output. This can be advantageous in noisy environments where headphones are required.Furthermore, the existing infrastructure is used optimally by meaningfully integrating the warning signal as an audio track in the communication signal, which contributes to a meaningful enrichment of the video transmission.

[0070] It may be provided that the output of the communication signal is adjustable. For the purposes of this disclosure, an adjustable output means that the way in which the communication signal is transmitted to the output unit can be flexibly adapted. This includes adjusting parameters such as volume, frequency, type of warning signal (acoustic, visual, or verbal), and selecting specific warning signals or channels. This adjustability makes it possible to adapt the output of the communication signal to the needs and preferences of the users as well as to the specific conditions of the environment, regardless of whether the output unit is located near or at a physically distant location from the actual automation system. The technical advantage of an adjustable output of the communication signal can lie in the flexibility and adaptability of the monitoring system.The ability to adjust output parameters ensures that warning signals are optimally perceived under varying environmental conditions and user preferences. This can be particularly advantageous when the output unit is located at a physical distance from the automation system, as the signals can be configured according to local conditions and communication requirements. This improves the efficiency and accuracy of remote monitoring by ensuring that critical warning signals are transmitted clearly and distinctly. Furthermore, this flexibility can contribute to easier operation and increased user satisfaction by allowing for individual settings for different users or specific application scenarios.

[0071] The output unit may be configured to provide, adapt, and / or disable specific warning signals of the communication signal based on a selectable output criterion. For the purposes of this disclosure, a selectable output criterion is a configurable parameter or condition that determines how and when specific warning signals are provided, adapted, or disabled by the output unit. These criteria can be selected by a user to adapt the output of warning signals to their individual needs and specific operating conditions. For the purposes of this disclosure, a specific warning signal is an individually defined acoustic, visual, or speech signal that indicates a particular type of fault or operating condition in the automation system.These warning signals can vary depending on the type and severity of the event and are specifically designed to draw a user's attention to critical situations.

[0072] For the purposes of this disclosure, "adaptation" means changing the output parameters of a specific warning signal to modify the nature of the warning signal. This includes changes to the volume, frequency, signal type, or other characteristics to adapt the warning signals to the respective requirements.

[0073] For the purposes of this disclosure, "blocking" means that certain warning signals are deactivated or blocked so that they are not transmitted to the output unit. This is used to suppress unnecessary or unwanted warning signals and to provide users only with relevant information. For the purposes of this disclosure, "based on selectable output criteria" means that the actions of providing, adapting, and blocking specific warning signals are carried out according to criteria defined by the users. These criteria take into account various aspects such as the type of warning signal, the severity of the event, the operating state, or environmental conditions.

[0074] This results in improved flexibility and adaptability of the monitoring system. Users can configure the output of warning signals based on specific criteria, enabling targeted and efficient communication. This can facilitate the monitoring of remote solutions, as events can be specifically targeted to users' attention via audible output. The ability to customize specific warning signals ensures optimal perception under varying environmental conditions, which is advantageous when the output unit is located at a different site than the automation system.

[0075] Blocking unnecessary warning signals can increase the relevance and clarity of the transmitted information, preventing users from being overwhelmed with irrelevant messages. This can contribute to easier operation and increased user satisfaction, especially when error messages and operating statuses are communicated directly to users via audio output. Furthermore, integrating the warning signal as an audio track within the communication signal optimizes the use of existing infrastructure, efficiently enriching video transmission and potentially improving the convenience of remote monitoring.

[0076] Up to this point, the disclosure has been described in relation to the claimed method. Features, advantages, or alternative embodiments can be attributed to the other claimed objects (e.g., the system, the device, the use of the device, or a computer program product) and vice versa. In other words, the subject matter claimed or described in relation to the device can be improved by features described or claimed in the context of the method, and vice versa.

[0077] According to another aspect of the disclosure, a device for providing a communication signal in an automation system is provided. The device comprises at least one interface for receiving a detected interference signal from at least one machine component of the automation system. Furthermore, the device comprises a processor unit configured to assign a selected warning signal to a communication signal based on the detected interference signal and to provide the communication signal.

[0078] For the purposes of this disclosure, an interface is a hardware or software component that enables the reception and transmission of data between different systems or devices. In the automation system, the interface serves to receive a detected interference signal from at least one machine component. It ensures that the detected sensor data is effectively forwarded to the processor unit. The interface can support various communication standards.

[0079] For the purposes of this disclosure, a processor unit is a computing unit or microprocessor responsible for processing data and executing instructions. In the device, the processor unit is configured to assign a selected warning signal to a communication signal based on the detected disturbance signal and to provide the communication signal. This includes analyzing the sensor data, selecting the appropriate warning signal, and assigning, in particular synchronizing, the warning signal with the communication signal.

[0080] The interface enables efficient and reliable transmission of sensor data from machine components to the device and thus to the processor unit. This allows for precise and timely detection of fault signals, supporting the early detection and diagnosis of malfunctions. As a result, downtime can be minimized and the operational readiness of the automation system increased. Furthermore, the interface can contribute to the optimal use of existing infrastructure by facilitating integration and communication between different systems and devices.

[0081] The processor unit analyzes detected interference signals and, based on this analysis, generates appropriate warning signals, which are then assigned to the communication signal. This ensures the precise and effective transmission of critical information to users, thus reducing response times to malfunctions and improving the efficiency of monitoring and controlling the automation system. The processor unit can also contribute to easier operation, particularly when error messages and operating states are communicated directly to users via audio output. According to another aspect of the disclosure, a system for the remote monitoring and / or control of at least one machine component of an automation system is provided. The system comprises at least one device and at least one output unit as disclosed.The output unit has a user interface through which a user selects, adjusts, and / or activates / deactivates a warning signal. The output unit provides visual and audible information and features a user interface that allows users to select, adjust, activate, or deactivate warning signals. The user interface can be integrated into screens, touchscreens, or include buttons or other input devices that enable intuitive and efficient interaction with the system, such as a monitoring system. An output unit with a user interface can achieve improved interactivity and usability.The ability to select, customize, or disable warning signals directly via the user interface allows users to flexibly adapt the system to their specific needs and environmental conditions. This can facilitate the monitoring of remote solutions, as events can be specifically targeted with audio output to draw the user's attention. Furthermore, the user interface simplifies the operation of the automation system, especially when error messages and operating states can be communicated directly as spoken words.

[0082] According to another aspect of the disclosure, a computer program is created, wherein the computer program comprises instructions. The instructions cause a device executing the program to carry out the method according to one of the method claims. For the purposes of this disclosure, a computer program can be a sequence of instructions or commands written in a programming language and executable by a computer or device. The computer program can control the functions and operations of the device by performing specific tasks and processes defined in the program code. The computer program can be provided as a signal via download or stored in a memory unit of a portable device, in particular the device according to the disclosure, containing computer-readable program code, to cause a system / device to execute instructions according to the method described above.

[0083] For the purposes of this disclosure, a device is a hardware unit or system that has the capability to execute a computer program and process data. This device may consist of various components, including a processor, memory units, interfaces, and output units. These work together to perform the tasks specified by the computer program.

[0084] According to another aspect, the disclosure provides for the use of the device disclosed in a system disclosed for monitoring the condition of at least one machine component of an automation system.

[0085] For the purposes of this disclosure, condition monitoring is the continuous or periodic inspection and analysis of the operating states and performance parameters of a machine component within an automation system. The objective of condition monitoring is to detect deviations from normal operating conditions at an early stage in order to identify and rectify malfunctions, failures, or inefficient operating conditions. This is achieved by acquiring and evaluating sensor data, which includes various physical or operational parameters of the machine component, and by transmitting a warning signal via communication. The technical advantage of condition monitoring lies in the ability to continuously monitor the condition of machine components and to react immediately to deviations from normal operating conditions.This can significantly reduce downtime of machine components by detecting and resolving potential malfunctions early. This increases the overall availability and efficiency of the automation system.

[0086] Integrating condition monitoring into a remote monitoring and control system allows users to focus their attention on critical events, thus simplifying the monitoring of remote solutions. Utilizing existing infrastructure, such as integrating the warning signal as an audio track within the communication signal as a video signal, can make monitoring more efficient and optimize resource utilization. Furthermore, condition monitoring can simplify and improve the operation of the automation system, especially when error messages are communicated directly to users via audio output.

[0087] The above embodiments and further developments can be combined with one another as appropriate. Further possible embodiments, further developments, and implementations of the disclosure also include combinations of features of the disclosure described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present disclosure.

[0088] The above can be summarized in other words and in a possible more concrete elaboration of the revelation as described below, whereby the following description is to be interpreted as not being restrictive for the revelation.

[0089] Based on an error classification system that categorizes errors by severity—from minor errors or warnings to critical errors—each easily distinguishable acoustic signal can be integrated into the audio track of the live stream (communication signal) and output simultaneously to the remote workstation (output unit). This signal can be a ringtone, a hub signal, or even a voice message. The acoustic signal can be generated synthetically using predefined rules, such as frequency modulation depending on the event's significance. The voice output can automatically generate error messages, similar to a voice assistant. Furthermore, pre-recorded audio files can be played back at the time of the event.In addition to acoustic signals or voice output of error messages, any other states, such as start, pause, stop, or end of processes, can also be output as acoustic events. Ultimately, all digitally captured events can be included in the live stream with an accompanying audio output. Settings can be selected so that users can choose which acoustic signals to include and which to mute.

[0090] Furthermore, the creation of a sound matrix for all important machine events that potentially have an impact on the operation of the machine tool (machine component) can be implemented. An application can be developed to selectively integrate the audio track into existing live video transmissions (live streams), so that the audio track is transmitted packaged with the respective streaming format, such as h.264. Additionally, text-to-speech generators can be used to incorporate error messages and other textual messages as audio into a live video transmission.

[0091] This eliminates the need for additional interfaces and transmission paths in the existing infrastructure.

[0092] The present disclosure will be explained in more detail below with reference to the exemplary embodiments shown in the schematic figures of the drawings. These show:

They illustrate embodiments and, in conjunction with the description, serve to explain the principles and concepts of the disclosure. Other embodiments and many of the mentioned advantages become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale.

[0100] In the figures of the drawing, identical, functionally equivalent, and equally effective elements, features, and components—unless otherwise specified—are to be provided with the same reference symbols.

[0101] Figure 1 shows an embodiment of a system 200 for remote monitoring and / or control of at least one machine component 11 of an automation system 10. The automation system 10 may contain a plurality of machine components 11-x. The system 200 comprises a device 1 designed to provide a communication signal 20 within the automation system 10.

[0102] The device 1 includes an interface 2 for receiving a detected interference signal 12 from at least one machine component 11 of the automation system 10 and a processor unit 3 which is configured to assign a selected warning signal 23 (see Figures 3, 5 and 6) to the communication signal 20 based on the detected interference signal 12 and to provide the communication signal 20.

[0103] Furthermore, the system 200 includes an output unit 40 with a user interface that allows a user to select, adjust, activate, and / or deactivate a warning signal 23. The communication signal 20 comprises combined video and audio transmissions over various channels. Assigning the selected warning signal 23 involves transmitting the warning signal 23 via an audio channel 22 of the communication signal 20, with the assignment occurring in real time. The communication signal 20 is encoded in a standardized video format.

[0104] The output unit 40 receives the communication signal and displays or outputs it. The output unit 40 can be a screen, a loudspeaker, a monitor, or another device used to present the received data in a user-friendly and understandable format. In the automation system 10, the output unit 40 is used to provide visual and audible warning signals as well as other relevant operating information. In an alternative configuration, the output unit 40 is physically separate from the automation system 10 and is part of a monitoring system, such as a control center. The output unit 40 can include operator terminals on the automation system 200, handheld devices such as laptops, tablets, or PDAs, and can be used as LCD displays and / or monitors in control centers.

[0105] The disturbance signal 12 comprises machine events based on digital sensor data from machine component 11 or machine components 11-x. The warning signal 23 comprises detected warning tones, synthetically generated and / or frequency-modulated warning tones, and / or voice messages. The warning signal 23 can also include a combination containing sensor data from at least one machine component 11 of the automation system 10.

[0106] Warning signal 23 is classified according to its criticality and includes minor faults with a first signal tone, medium faults with at least a second signal tone that differs from the first signal tone, and serious faults with at least a third signal tone that differs from the first and / or second signal tone. It also includes operating states such as a start state, a pause state, a stop state, and / or a final state of a process of machine component 11, with each criticality and operating state being signaled by a corresponding signal tone.

[0107] The communication signal 20 is provided in real time to an output unit 40 and / or stored in a storage unit 30. The output of the communication signal 20 is adjustable, and the output unit 40 is configured to provide, adjust, and / or block specific warning signals 24, 25, 26, 27, 28 as shown in Figure 5 of the communication signal 20, based on a selectable output criterion.

[0108] The device 1 of the system 200 is designed to carry out the method 100 described in detail below with reference to Figure 2.

[0109] Figure 2 shows an embodiment of the method 100 for providing a communication signal 20 according to Figures 3 and 4 in an automation system 10, which includes at least one machine component 11. The method 100 comprises several process steps. In a first process step, a disturbance signal 12 is detected 110 from at least one machine component 11 of the automation system 10. Subsequently, a selected warning signal 23 is assigned 120 to a communication signal 20, based on the detected disturbance signal 12. In a further process step 130, the communication signal 20 is provided.

[0110] The communication signal 20, as shown in Figure 3, includes combined video and audio transmissions over various channels. The assignment of the selected warning signal 23 involves transmitting the warning signal 23 via an audio channel 22 of the communication signal 20 and is time-synchronized, specifically in real time. The communication signal 20 is encoded in a standardized video format.

[0111] The fault signal 12 comprises machine events based on digital sensor data from machine component 11. The warning signal 23 includes detected warning tones, synthetically generated and / or frequency-modulated warning tones, and / or voice messages. Furthermore, the warning signal can be a combination of sensor data from at least one machine component 11 of the automation system 10. The warning signal 23 is classified according to its criticality, encompassing minor faults with a first signal tone, medium faults with at least a second signal tone that differs from the first, and severe faults with at least a third signal tone that differs from the first and / or second. Operating states such as a start state, a pause state, a stop state, and / or an end state of a process of machine component 11 are also signaled by corresponding signal tones.

[0112] The communication signal 20 is provided to the output unit 40 in real time and / or stored in the storage unit 30. The output of the communication signal 20 is adjustable. The output unit 40 is configured to provide, adjust, and / or block specific warning signals 24, 25, 26, 27, 28 of the communication signal, based on a selectable output criterion.

[0113] Figure 3 shows a schematic representation of the assignment of the warning signal 23 to the communication signal 20. The communication signal 20 has several different channels 20-x, most notably a video channel 21. The warning signal 23 is assigned to the audio channel 22 of the communication signal 20 in process step 120 of process 100. This assignment can include multiplexing technology, audio encoding, in particular Advanced Audio Coding (AAC), a container format, in particular MP4, MKV, and sound overlay software.

[0114] Assigning the warning signal 23 to the communication signal 20 increases the efficiency and precision of monitoring the automation system 10 by ensuring that audio and video data are transmitted synchronously in real time, enabling an immediate and accurate response to malfunctions. It also facilitates the monitoring of remote solutions, as acoustic signals draw users' attention to critical events without requiring constant visual monitoring. The existing infrastructure is optimally utilized by intelligently integrating the warning signal 23 into the audio channel 22 of the communication signal 20, thus improving overall resource utilization. Simultaneously, the operation of the automation system 10 is simplified by directly outputting, customized warning signals 23, which is particularly advantageous in noisy environments.This synchronization of audio and video also promotes precise fault diagnosis and increases the convenience of remote monitoring, as unnecessary warnings are suppressed and relevant information is provided in a targeted manner.

[0115] Figure 4 shows the structure of the communication signal 20 within the automation system 10. The communication signal 20 comprises several channels, including video channel 21 and audio channel 22, which are represented as different waveforms. The communication signal 20 is generated and managed by the device 1, which processes the interference signal 12 received by at least one machine component 11 of the automation system 10. Video channel 21 is responsible for transmitting visual data, while audio channel 22 is used for transmitting acoustic data, including selected warning signals 23. These warning signals are transmitted via audio channel 22 and are based on the detected interference signal 12. The communication signal 20 may also include additional channels, collectively referred to as 22-x, which can be used for other types of data transmission depending on the requirements of the system 200.

[0116] The communication signal 20 is encoded and synchronized to ensure real-time transmission throughout the system 200. It is stored in the memory unit 30 and can be retrieved or modified via the output unit 40 as required by the user. The selected warning signal 23 in audio channel 22 is processed by the processor unit 3 to ensure that it is appropriately categorized and synchronized with the visual data in video channel 21.

[0117] Figure 5 shows a schematic representation of an assigned selected warning signal 23 as it transmits various specific warning signals 24, 25, 26, 27, 28. These specific warning signals 24, 25, 26, 27, 28 can represent different criticality levels or types of warnings within the automation system 10. The selected warning signal 23 is generated by the device 1 and transmitted via the audio channel 22 of the communication signal 20.

[0118] The waveform of each specific warning signal 24, 25, 26, 27, 28 indicates the type and urgency of the warning, with signal 24 representing the lowest criticality and signal 28 the highest criticality or urgency. Each signal is processed and managed by the processor unit 3 within the device 1. The device 1 receives a disturbance signal 12 from at least one machine component 11 via the interface 2 and assigns the corresponding warning signal 23 based on the type and severity of the disturbance signal 12.

[0119] This process occurs in real time, with the selected warning signal 23 being encoded within the audio channel 22 of the communication signal 20. The communication signal 20 also contains a video component, which is transmitted via a video channel 21. The assigned specific warning signals 24 to 28 can be stored in the storage unit 30 and output to the output unit 40 for further processing or user interaction.

[0120] Figure 6 shows the waveform of a selected warning signal 23 as transmitted via audio channel 22 within the communication signal 20 in the automation system 10. The selected warning signal 23 represents a combination of sensor data originating from at least one machine component 11 of the automation system 10 and processed by the processor unit 3. This combination includes both an audible and an inaudible portion of the warning signal to provide comprehensive monitoring data while ensuring user-friendliness. The waveform shows three specific sections of the selected warning signal 23, labeled 231, 232, and 233. Section 232 represents the audible portion of the warning signal, which is directly perceptible to the user and typically signals a critical event or system warning.Sections 231 and 233 correspond to the inaudible portions in which additional sensor data is embedded. This sensor data includes information on parameters such as temperature, pressure, vibration, humidity, or electrical signals that are important for monitoring the operating status of machine component 11.

[0121] The inaudible sections 231 and 233 are embedded in the warning signal using modulation techniques, specifically frequency or amplitude modulation. These segments are not directly audible to the user but can be demodulated by special software to retrieve the embedded sensor data. This approach allows for the integration of detailed operational data into the warning signal without overwhelming the user with excessive audible warnings.

[0122] The features of Figure 5 and Figure 6 can be combined, meaning that the warning signal 23 from Figure 5 corresponds to the audible component 232 of the warning signal 23 in Figure 6.

[0123] Integrating this sensor data into the warning signal 23 offers a technical advantage because the existing audio channel 22 of the communication signal 20 is used efficiently. This allows additional critical information to be transmitted without requiring separate channels or signals. The combined warning signal provides improved monitoring capabilities, as users receive real-time data on the condition of the machine component 11, contributing to precise fault detection, predictive maintenance, and extending the service life of the machine components 11 and / or the automation system 10.

[0124] Furthermore, the combined warning signal improves the reliability and accuracy of fault detection by reducing the probability of false alarms and ensuring that only significant problems are reported to the user. The audible component 232 of the signal provides immediate alerting, while the inaudible components 231 and 233 provide valuable additional information that can be accessed as needed. The disclosed procedure increases the overall efficiency of the automation system 10 by enabling more effective remote monitoring and faster responses to potential problems.

[0125] The combined approach also ensures that user-friendliness is maintained, as critical warnings are transmitted acoustically, while additional data for deeper analysis remains available as needed. The versatility of this system 200 allows for individual adaptation of the monitoring to the specific needs of the automation system 10, contributing to improved operational safety and efficiency. Figures 5 and 6 show the selected warning signal 23 as it is transmitted via an audio channel 22 within a communication signal 20 in an automation system 10. These figures show only a single mono channel of the audio channel 22, which integrates both audible and inaudible components within the same waveform. Not shown in the figures is that the audio channel 22 comprises at least two mono channels.

[0126] The selected warning signal 23 shown in Figures 5 and 6 can also be transmitted in a second, separate mono channel. In particular, the audible components 232 of the warning signal, which are crucial for immediate user warning, such as segments 24, 25, 26, 27, and 28 in Figure 5, could be transmitted in the first mono channel. Meanwhile, the inaudible components 231 and 233 of the warning signal 23, as shown in Figure 6, which include additional sensor data from at least one machine component 11, could be transmitted separately in the second mono channel.

[0127] Integrating two mono channels into audio channel 22 can offer enhanced flexibility and functionality for signal transmission. In this configuration, different data types can be transmitted simultaneously, with one mono channel focusing on audible alerts and the other on inaudible, sensor-based information. The inaudible components, including segments 231 and 233 in Figure 6, can contain critical operating parameters such as temperature, pressure, or vibration data, embedded using modulation techniques and transmitted separately in the second mono channel from the audible alarm in the first. This enables a more precise and efficient monitoring system.

[0128] Furthermore, this approach optimizes the use of existing infrastructure and bandwidth, ensuring that both audible alarms and additional data are transmitted without interference. The stereo configuration formed by the two mono channels not only provides a richer and more informative signal but also allows for the routing of different information streams to different output devices. For example, the first mono channel can be output via a loudspeaker to deliver immediate audible alarms, while the second mono channel can provide additional data for further analysis on a screen.

[0129] This approach improves the overall monitoring capability of the automation system 10 and makes it easier to distinguish between critical audible warnings and other operational data that require further interpretation by hardware or software. The use of at least two mono channels increases the precision and efficiency of signal transmission and processing, resulting in improved monitoring and control of the automation system.

[0130] The procedure 100 described in the preceding figures is applied here, wherein the processing of the interference signal 12 and the assignment of the selected warning signal 23 follow a sequence of procedure steps 110, 120, and 130. The output unit 40 allows adjustments or filtering of the warning signals 23 based on user-defined criteria to ensure that the most relevant warnings are effectively communicated.

[0131] Overall, the examples show how an acoustic video stream overlay can be provided.
