[0046] As described above, although the IOLINK communication protocol performs well in the field of industrial automation, in a strong electromagnetic interference environment, the data exchange and signal transmission between the controller and the communication device can still be seriously affected, leading to an increase in the error rate, and even causing communication failure, thereby affecting the stable operation of the whole production line.

[0047] The inventors propose a communication system and method. The sensor unit and the controller of the communication system are connected through an IOLINK communication interface. A signal filter is arranged on the signal transmission path between the controller and the communication device. The controller is configured to receive an environment signal from the sensor unit, and send the environment signal to the communication device through the signal filter. The signal filter is configured to remove noise signals and interference signals in the environment signal. In this way, the signal filter arranged on the signal transmission path between the controller and the communication device can remove noise signals and interference signals in the environment signal, thereby improving the signal quality of the environment signal transmitted to the communication device and reducing the error rate of data exchange and signal transmission. Moreover, the reduction of noise signals and interference signals means that the error rate in the communication process will be reduced, thereby reducing the probability of causing communication failure and enhancing the reliability of the entire communication system.

[0048] In order to better understand the technical scheme of the present application, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] Referring to Figure 1 , the figure is a schematic diagram of a communication system provided by an embodiment of the present application. As shown in the communication system, Figure 1 , the communication system comprises a sensor unit 101, a controller 102 and a signal filter 103.

[0050] The sensor unit 101 and the controller 102 are connected through an open standard serial communication protocol IOLINK communication interface. The signal filter 103 is arranged on the signal transmission path between the controller 102 and a communication device 104 which performs signal transmission with the controller 102.

[0051] It should be noted that the communication device 104 can be a remote monitoring device, a data recorder or other device which needs to receive the environment signals. The specific communication device is not limited in the present application.

[0052] S101: The controller 102 receives an environment signal from the sensor unit 101.

[0053] The sensor unit 101 is responsible for sensing and collecting environment data (such as temperature data, humidity data, pressure data, etc.), and converting the environment data into an electrical signal or other transmittable form (i.e. an environment signal).

[0054] S102: The controller 102 sends the environmental signal to the communication device through the signal filter 103, wherein the signal filter is used to remove the noise signal and interference signal in the environmental signal.

[0055] The main function of the signal filter 103 is to remove the noise signal and interference signal in the environmental signal. These noise signals and interference signals may come from various external factors (such as electromagnetic interference, mechanical vibration, etc.), which may affect the accuracy and integrity of the environmental signal if not handled. Through filtering processing, the signal filter can ensure that only pure environmental signals are sent to the communication device, thereby improving the accuracy and integrity of the signal.

[0056] In summary, the embodiment of the present application discloses a communication system, the sensor unit and the controller of the communication system are connected through the IOLINK communication interface, and the signal filter is located on the signal transmission path between the controller and the communication device; the controller is used to receive the environmental signal from the sensor unit; the environmental signal is sent to the communication device through the signal filter, wherein the signal filter is used to remove the noise signal and interference signal in the environmental signal. Therefore, by setting the signal filter on the signal transmission path between the controller and the communication device, the noise signal and interference signal in the environmental signal can be removed, thereby improving the signal quality of the environmental signal transmitted to the communication device and reducing the error rate of data exchange and signal transmission. Moreover, the reduction of noise signal and interference signal means that the error rate in the communication process will be reduced, thereby reducing the probability of causing communication failure and enhancing the reliability of the entire communication system.

[0057] Referring to Figure 2 , the figure is another schematic diagram of a communication device provided by the embodiment of the present application. As Figure 2 shown in the communication system, it includes a sensor unit 101, a controller 102 and a signal filter 103.

[0058] Among them, the sensor unit 101 includes a plurality of sensors, including but not limited to temperature sensors, pressure sensors, position sensors, flow sensors, photoelectric sensors, etc., each sensor and the controller 102 are connected through the open standard serial communication protocol IOLINK communication interface. The signal filter 103 is located on the signal transmission path between the controller 102 and the communication device which performs signal transmission with the controller 102.

[0059] It should be noted that the communication device 104 can be a remote monitoring device, a data recorder or other device that needs to receive these environmental signals. For specific communication devices, the present application does not make any limitation.

[0060] S201: The controller 102 receives the environmental signal from each sensor of the sensor unit 101.

[0061] In some specific implementations, the controller 102 needs to first identify which sensors should be communicated with. This is because in a complex communication system, there can be multiple sensor units and a large number of sensors, and the controller 102 is usually only interested in the data of a part of the sensors.

[0062] Specifically, the controller 102 first obtains the MAC addresses of all sensors by sending a query request or listening to the broadcast messages on the network. Once the controller 102 collects the MAC addresses of all sensors, it compares these MAC addresses with a locally saved list of MAC addresses of sensors to be connected. This list is usually created in the configuration phase of the communication system 100 and contains the MAC addresses of all sensors that should be communicated with the controller 102. If the MAC address of a sensor matches a MAC address in the list, the controller 102 considers this sensor to be communicated with and establishes a connection with the sensor. In this way, the controller 102 can start receiving the environmental signals from the sensor.

[0063] S202: The controller 102 sends the merged environmental signals to the communication device 104 through the signal filter 103, wherein the signal filter is used to remove noise signals and interference signals in the environmental signals.

[0064] The controller 102 not only receives the environmental signals from each sensor of the sensor unit 101, but also needs to perform merging processing on these environmental signals. The merging processing can involve combining multiple environmental signals into a composite environmental signal, or integrating the environmental signals into a signal package for subsequent processing or transmission.

[0065] Referring to Figure 3 , the figure is a schematic diagram of the connection between the controller and the communication device provided by the embodiment of the application. The merged environmental signals are sent to the communication device 104 through the signal filter 103. The main function of the signal filter 103 is to remove noise signals and interference signals in the environmental signals, which can come from external electromagnetic environment, mechanical vibration or other factors. If these noise signals and interference signals are not removed, they can affect the accuracy and reliability of the communication. Then, the signal filter 103 disclosed in the application can identify and remove these noise signals and interference signals through specific filtering algorithms or circuits, so as to ensure that the environmental signals sent to the communication device 104 are as pure as possible.

[0066] S203: The controller 102 receives feedback data from the communication device 104, the feedback data indicating the analysis result of the filtered ambient signal by the communication device 104.

[0067] The communication device 104 can perform further analysis and processing on the filtered ambient signal received from the signal filter 103, such as interpretation, data conversion, pattern recognition, anomaly detection, etc., depending on the design and function of the communication device 104. After the analysis is completed, the communication device 104 generates feedback data containing information of the analysis result.

[0068] S204: The controller 102 adjusts the filtering parameters of the signal filter 103 according to the feedback data.

[0069] The controller 102 uses the feedback data received from the communication device 104 to adjust the filtering parameters of the signal filter 103. The filtering parameters determine how the signal filter 103 removes noise signals and interference signals from the ambient signal according to the current environmental conditions and communication requirements, thereby ensuring that the filtered ambient signal has the best accuracy and integrity. Specifically, adjusting the filtering parameters of the signal filter 103 can involve changing the cutoff frequency, bandwidth, phase response, etc. of the signal filter 103. By adjusting these parameters, the controller 102 can change the filtering characteristics of the filter to adapt to different environmental conditions or communication requirements.

[0070] For example, if the feedback data indicates that the communication device 104 encounters excessive high-frequency noise interference when analyzing the ambient signal, the controller 102 can lower the cutoff frequency of the signal filter 103 to remove these high-frequency noise more effectively. Conversely, if the communication device 104 detects that certain low-frequency components in the ambient signal are particularly important for analysis, the controller 102 can increase the bandwidth of the signal filter 103 to ensure that these low-frequency components can pass through the signal filter 103 smoothly.

[0071] In this way, by dynamically adjusting the filtering parameters, the controller 102 can ensure that the signal filter 103 always remains in the best working state, thereby improving the performance and reliability of the entire communication system 100.

[0072] S205: The controller 102 detects the spectrum usage in the signal transmission path, the spectrum usage including at least one of an idle frequency band and an occupied frequency band.

[0073] The spectrum usage typically includes information of both free bands and occupied bands. Free bands refer to spectrum regions that are currently not used by any device or system, which can be used for new communication links or data / signal transmission. Occupied bands refer to spectrum regions that are already occupied by other devices or systems. By accurately identifying occupied bands, the controller 102 can avoid establishing new communication links on the already occupied spectrum, thus preventing potential spectrum conflicts and interference.

[0074] The controller 102 can obtain the spectrum usage through a built-in spectrum analyzer or an interface with other spectrum management devices. The spectrum analyzer can scan the spectrum in the signal transmission path in real time or periodically to identify free and occupied bands. The interface with other spectrum management devices can provide more detailed and accurate information about spectrum allocation, usage, occupation rules, etc.

[0075] S206: The controller 102 adjusts the transmission parameters of the controller 102 according to the spectrum usage, the transmission parameters including any one or more of the transmission frequency, the transmission modulation mode, and the transmission power of the environmental signal transmitted by the signal filter 103 to the communication device 104.

[0076] The controller 102 dynamically adjusts its transmission parameters using the spectrum usage obtained from the spectrum detection step. The transmission parameters include transmission frequency, transmission modulation mode, and transmission power, etc., which together determine how the controller 102 transmits the environmental signal to the communication device 104 through the signal filter 103.

[0077] Specifically, when selecting the transmission frequency, the controller 102 will give priority to free bands to avoid interference with existing communications. In the case of multiple free bands available for selection, the controller 102 will consider factors such as spectrum efficiency, signal propagation characteristics, device compatibility, etc., to select the most suitable band. This helps to ensure the continuity and stability of communication, while improving the efficiency of spectrum resource utilization.

[0078] The transmission modulation mode determines how to convert the data signal into a suitable radio frequency signal for transmission. Specifically, the controller 102 will select the most suitable modulation mode for the current environment according to factors such as spectrum usage, signal transmission requirements, and device capabilities. For example, in the case of tight spectrum resources, the controller 102 may choose a modulation mode with higher spectrum efficiency to maximize data transmission rate.

[0079] The transmission power determines the intensity and coverage of the environmental signal during transmission. Specifically, the controller 102 dynamically adjusts the transmission power according to factors such as the distance of the communication device 104, the required communication quality, and the spectrum usage. For example, in the case of spectrum resource shortage or potential interference, the controller 102 may reduce the transmission power to reduce interference while ensuring the reliability of communication.

[0080] In this way, by dynamically adjusting these transmission parameters, the controller 102 can ensure efficient and reliable communication in complex communication environments. This adaptive adjustment mechanism is crucial for improving the efficiency of spectrum resource usage, reducing interference, and improving the performance of the entire communication system 100. It not only helps to achieve more efficient communication, but also reduces the energy consumption and operating costs of the communication system 100, and improves the overall economic benefits.

[0081] S207: The controller 102 receives a plurality of historical environmental signals from the sensor unit in a historical time period.

[0082] In the wireless communication and environmental monitoring system, the controller 102 plays a crucial role, not only responsible for real-time processing and analysis of the current environmental signal, but also needs to receive and store historical environmental data from the sensor unit 101. Among them, the historical environmental signal refers to the signal indicating the environmental data collected by the sensor unit 101 and transmitted to the controller 102 in a certain time period (i.e. historical time period) in the past. Each environmental data is the value of the environmental parameter (such as temperature, humidity, pressure, etc.) perceived by the sensor unit 101 at a specific time point in the historical time period. By accumulating a large amount of historical environmental data, the controller 102 can analyze the trend, periodicity and other potential laws of these historical environmental data, thereby providing a basis for future environmental signal prediction.

[0083] S208: The controller 102 predicts a predicted environmental signal at a target time based on the plurality of historical environmental signals.

[0084] The controller 102 uses the received plurality of historical environmental signals to predict the environmental signal at a certain specific time in the future (i.e. target time) through machine learning algorithms, time series analysis or other prediction techniques. It should be noted that the specific prediction method is not limited in the present application.

[0085] S209: At the target time, the controller 102 adjusts the filtering parameters of the signal filter 103 according to the predicted environmental signal, so that the real environmental signal at the target time from the sensor unit 101 is transmitted to the communication device 104 through the signal filter 103 with the adjusted filtering parameters.

[0086] When the target time is reached, the controller 102 adjusts the filtering parameters (such as cutoff frequency, bandwidth, phase response, etc.) of the signal filter 103 according to the previously predicted predicted environment signal, aiming to ensure that the signal filter 103 can effectively remove noise signals and interference signals while retaining important information in the real environment signal, thereby optimizing the performance of the signal filter 103 to better process the real environment signal at the target time.

[0087] Subsequently, the controller 102 sends the real environment signal at the target time (from the sensor unit 101) to the communication device 104 through the signal filter 103 with adjusted filtering parameters. In this way, the communication device 104 can receive the optimized processed signal, thereby more accurately understanding the current environmental conditions.

[0088] In summary, the embodiments of the present application disclose a communication system, which is connected between the sensor unit and the controller through the IOLINK communication interface, and the signal filter is located on the signal transmission path between the controller and the communication device; the controller is used to receive the environment signal from the sensor unit; and the environment signal is sent to the communication device through the signal filter, wherein the signal filter is used to remove noise signals and interference signals in the environment signal. Thus, by setting the signal filter on the signal transmission path between the controller and the communication device, the noise signals and interference signals in the environment signal can be removed, ensuring that the environment signal sent to the communication device 104 is as pure as possible, thereby improving the signal quality of the environment signal transmitted to the communication device, reducing the error rate of data exchange and signal transmission. Moreover, the reduction of noise signals and interference signals means that the error rate in the communication process will be reduced, thereby reducing the probability of causing communication failure and enhancing the reliability of the entire communication system. Furthermore, the controller can detect the frequency spectrum usage in the signal transmission path, including the idle frequency band and the occupied frequency band, thereby avoiding establishing a new communication link on the occupied frequency spectrum, reducing the possibility of spectrum conflict and interference. Moreover, the controller can receive and store historical environment signals from the sensor unit, and predict the environment signal at a specific future time through machine learning algorithms, time series analysis, etc. This prediction capability enables the system to make adjustments in advance to adapt to future environmental changes. At the target time, the controller adjusts the filtering parameters of the signal filter according to the predicted environment signal, ensuring that the signal filter can more effectively process the real environment signal, improving the adaptive ability and response speed of the system.
