[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 may still be seriously affected, resulting in an increase in the error rate and even causing communication failures, thereby affecting the stable operation of the entire production line.

[0047] After research, the inventor proposed a communication system and method, in which the sensor unit and the controller of the communication system are connected through an 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 the 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 the 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. In addition, 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 failures and enhancing the reliability of the entire communication system.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] See also Figure 1 , which is a schematic diagram of a communication system provided by an embodiment of the present application. Figure 1 The communication system shown includes a sensor unit 101 , a controller 102 and a signal filter 103 .

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

[0051] It should be noted that the communication device 104 may be a remote monitoring device, a data logger or other device that needs to receive these environmental signals. This application does not limit the specific communication device.

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

[0053] The sensor unit 101 is responsible for sensing and collecting environmental data (such as temperature data, humidity data, pressure data, etc.), and converting the environmental data into electrical signals or other transmittable forms (ie, environmental signals).

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

[0055] The main function of the signal filter 103 is to remove noise signals and interference signals from the environmental signal. These noise signals and interference signals may come from various external factors (such as electromagnetic interference, mechanical vibration, etc.), and if not processed, they may affect the accuracy and integrity of the environmental signal. Through filtering, 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, in which the sensor unit and the controller of the communication system are connected via an 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 the interference signal in the environmental signal. Thus, by setting the signal filter on the signal transmission path between the controller and the communication device, the noise signal and the 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 signals and interference signals means that the error rate in the communication process will be reduced, thereby reducing the probability of causing communication failures and enhancing the reliability of the entire communication system.

[0057] See also Figure 2 , which is a schematic diagram of another communication device provided in an embodiment of the present application. Figure 2 The communication system shown includes a sensor unit 101 , a controller 102 and a signal filter 103 .

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

[0059] It should be noted that the communication device 104 may be a remote monitoring device, a data logger or other device that needs to receive these environmental signals. This application does not limit the specific communication device.

[0060] S201 : The controller 102 receives an 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 communicate with it. This is because in a complex communication system, there may be multiple sensor units and a large number of sensors, and the controller 102 usually only cares about the data of a part of the sensors.

[0062] Specifically, the controller 102 first obtains the Media Access Control (MAC) addresses of all sensors by sending a query request or listening to broadcast messages on the network. Once the controller 102 collects the MAC addresses of all sensors, it will compare these MAC addresses with the locally stored MAC address list of sensors to be connected. This list is usually created during the configuration phase of the communication system 100 and contains the MAC addresses of all sensors that should communicate with the controller 102. If the MAC address of a sensor matches a MAC address in the list, the controller 102 will assume that the sensor should communicate with it and will establish a connection with the sensor. In this way, the controller 102 can start receiving environmental signals from the sensor.

[0063] S202: After the controller 102 combines each environmental signal, it sends the combined environmental signal to the communication device 104 through the signal filter 103, wherein the signal filter is used to remove noise signals and interference signals from the environmental signal.

[0064] The controller 102 not only receives the environmental signals from the various sensors of the sensor unit 101, but also needs to combine and process these environmental signals. The combination process may 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] See also Figure 3 , which is a schematic diagram of the connection between a controller and a communication device provided in an embodiment of the present application. The merged environmental signal is sent to the communication device 104 through the signal filter 103. Among them, the main function of the signal filter 103 is to remove noise signals and interference signals in the environmental signal, and these noise signals and interference signals may come from the external electromagnetic environment, mechanical vibration or other factors. If these noise signals and interference signals are not removed, they may affect the accuracy and reliability of communication. Then, the signal filter 103 disclosed in the present application can identify and remove these noise signals and interference signals through a specific filtering algorithm or circuit, thereby ensuring that the environmental signal sent to the communication device 104 is as pure as possible.

[0066] S203: The controller 102 receives feedback data from the communication device 104, where the feedback data indicates an analysis result of the communication device 104 on the filtered environmental signal.

[0067] The communication device 104 further analyzes and processes the filtered environmental signal received from the signal filter 103, such as interpreting the filtered environmental signal, 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, which includes information on the analysis results.

[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 removes noise signals and interference signals from the environmental signal according to the current environmental conditions and communication requirements, thereby ensuring that the filtered environmental signal has the best accuracy and integrity. Specifically, adjusting the filtering parameters of the signal filter 103 may 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 too much high-frequency noise interference when analyzing the ambient signal, the controller 102 may reduce the cutoff frequency of the signal filter 103 to more effectively remove the high-frequency noise. On the contrary, if the communication device 104 detects that some low-frequency components in the ambient signal are particularly important for analysis, the controller 102 may increase the bandwidth of the signal filter 103 to ensure that these low-frequency components can pass through the signal filter 103 smoothly.

[0071] Therefore, 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 spectrum usage in the signal transmission path, where the spectrum usage includes at least one of an idle frequency band and an occupied frequency band.

[0073] The spectrum usage usually includes information about idle frequency bands and occupied frequency bands. Idle frequency bands refer to spectrum areas that are not currently used by any device or system, and these frequency bands can be used for new communication links or data / signal transmission. Occupied frequency bands refer to spectrum areas that have been occupied by other devices or systems. By accurately identifying occupied frequency bands, the controller 102 can avoid establishing new communication links on occupied spectrum, thereby preventing potential spectrum conflicts and interference.

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

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

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

[0077] Specifically, when selecting a transmission frequency, the controller 102 will give priority to idle frequency bands to avoid interference with existing communications. When multiple idle frequency bands are available, the controller 102 will comprehensively consider factors such as spectrum efficiency, signal propagation characteristics, and device compatibility to select the most suitable frequency band. This helps ensure the continuity and stability of communications while improving the efficiency of spectrum resource use.

[0078] The transmission modulation mode determines how to convert the data signal into a radio frequency signal suitable for transmission. Specifically, the controller 102 will select the modulation mode that best suits the current environment based on factors such as spectrum usage, signal transmission requirements, and device capabilities. For example, when spectrum resources are tight, the controller 102 may select a modulation mode with higher spectrum efficiency to maximize the data transmission rate.

[0079] The transmission power determines the strength and coverage of the environmental signal during the transmission process. 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 tight spectrum resources or potential interference, the controller 102 may reduce the transmission power to reduce interference while ensuring the reliability of communication.

[0080] Thus, by dynamically adjusting these transmission parameters, the controller 102 can ensure efficient and reliable communication in a complex communication environment. This adaptive adjustment mechanism is crucial to improving the efficiency of spectrum resource use, 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, thereby improving the overall economic benefits.

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

[0082] In the wireless communication and environmental monitoring system, the controller 102 plays a vital role. It is not only responsible for real-time processing and analysis of current environmental signals, but also needs to receive and store historical environmental data from the sensor unit 101. Among them, the historical environmental signal is a signal indicating the environmental data collected by the sensor unit 101 and transmitted to the controller 102 in a certain time period in the past (i.e., the historical time period). 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 the predicted environmental signal at the target moment based on multiple historical environmental signals.

[0084] The controller 102 uses the received multiple historical environmental signals to predict the environmental signal at a specific moment in the future (ie, the target moment) through machine learning algorithms, time series analysis, or other prediction techniques. It should be noted that the present application does not limit the specific prediction method.

[0085] S209 : At the target moment, 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 moment is sent to the communication device 104 through the signal filter 103 with adjusted filtering parameters, and the real environmental signal at the target moment comes from the sensor unit 101 .

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

[0087] Subsequently, the controller 102 sends the real environment signal (from the sensor unit 101) at the target time 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 Haojie signal, so as to understand the current environment conditions more accurately.

[0088] In summary, the embodiment of the present application discloses a communication system, in which the sensor unit and the controller of the communication system are connected through an 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 the interference signal in the environmental signal. Thus, by setting the signal filter on the signal transmission path between the controller and the communication device, the noise signal and the interference signal in the environmental signal can be removed, ensuring that the environmental signal sent to the communication device 104 is as pure as possible, 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. In addition, 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 failures and enhancing the reliability of the entire communication system. Further, the controller can detect the spectrum usage in the signal transmission path, including idle frequency bands and occupied frequency bands, thereby avoiding the establishment of new communication links on the occupied spectrum, reducing the possibility of spectrum conflicts and interference. In addition, the controller can receive and store historical environmental signals from the sensor unit, and predict environmental signals at specific moments in the future through machine learning algorithms, time series analysis and other technologies. This predictive capability enables the system to make adjustments in advance to adapt to future environmental changes. At the target time, the controller adjusts the filter parameters of the signal filter based on the predicted environmental signal, ensuring that the signal filter can process the real environmental signal more effectively, improving the system's adaptability and response speed.
