These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0074] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions 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, including but not limited to the combination of multiple embodiments, belong to the scope of protection of this application.

[0075] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0076] In most cases, one communication mode can meet the communication requirements between various devices or modules in the system. However, in actual applications, due to factors such as the installation location, environment, terrain, and system construction cost between modules in the system in different application scenarios, some devices or modules may be in communication blind spots.

[0077] The emergence of dual-mode communication technology provides more flexibility for the communication connection of each device or module in the system. However, in the existing technology, the communication mode in the general dual-mode communication, whether it is wired communication or wireless communication, is attributed to electromagnetic wave communication. Electromagnetic wave communication has its unique physical property advantages and is also the most deeply studied communication technology. In theory, it can solve all communication needs.

[0078] However, in actual applications, due to environmental factors such as indoor and outdoor geographical environment, weather, magnetic field interference, etc., under conditions of limited resources or high cost requirements, and when the distribution of electronic equipment in the system is complex, electromagnetic wave communication may not be able to achieve real-time full coverage, or its transmission link needs to take a detour, increasing communication delay, or requiring additional communication lines or wireless transceiver nodes. In other words, single sampling electromagnetic wave communication cannot simultaneously meet the requirements of system communication timeliness and resource utilization economy.

[0079] Figure 1 A schematic diagram of the layout structure of a large-scale hydrological monitoring system provided in this application. Figure 1 As shown, a plurality of hydrological information monitoring devices floating on the water surface are distributed in the water surface area 100, wherein the monitoring device 110 is the master control device, and the monitoring devices 120 and 130 are slave control devices. As can be seen from the figure, the wireless communication coverage range of the monitoring device 110 is the sector 140, and the monitoring devices 120 are all located in the sector 140, and can smoothly receive the control instructions given by the monitoring device 110, but the monitoring device 130 is outside the sector 140, and the distance between it and the monitoring device 110 is relatively far, for example, greater than 100 meters. At this time, if the monitoring device 130 is also included in the communication range of the monitoring device 110, ideally, it is only necessary to install wireless communication modules with different sector orientations on the monitoring device 110, or to transfer information through the monitoring device 120. However, the actual situation is that all monitoring devices are powered by solar panels installed thereon, which limits the installation space of the antennas equipped with wireless communication modules, and because the solar panels are oriented to follow the rotation range of the sun, they are only allowed to be transmitted from a certain period of time. Figure 1 Wireless communication is carried out from the bottom to the top, while communication from the top to the bottom is blocked by the solar panels and cannot be communicated. This makes the above two solutions unfeasible. Then another solution is to lay a communication line between the monitoring device 110 and the monitoring device 130 underwater or on the water surface, which greatly increases the communication cost of the system and is less economical.

[0080] Therefore, in order to meet the technical problem of improving the economic efficiency of communication while maintaining the communication requirements of the system. The inventive concept of this application is:

[0081] Mechanical wave communication, which is different from electromagnetic wave communication, is introduced. That is, the characteristics of mechanical waves propagating in solid or liquid media, such as metal brackets, pipes, and water, are utilized, and mechanical wave communication is used as the second communication mode of the dual-mode communication module. This saves the resource investment required to lay additional communication lines, thereby eliminating communication blind spots and improving the economy of communication.

[0082] The processing method for the dual-mode communication module provided by the present application is described in detail below.

[0083] Figure 2 A flowchart of a processing method for a dual-mode communication module provided in an embodiment of the present application is shown. Figure 2 As shown, the specific steps of the method include:

[0084] S201. Broadcast a first signal to a target area through a first communication mode.

[0085] In this step, the first signal is used to instruct at least one first dual-mode communication module to suspend the channel quality detection function of the second communication mode, and the target area includes at least one first dual-mode communication module and at least one second dual-mode communication module. The second dual-mode communication module is currently unable to receive the first signal.

[0086] The first communication mode includes: electromagnetic wave communication, which includes wireless communication and wired communication. The second communication mode includes: mechanical wave communication, which includes: sound wave communication or ultrasonic wave communication in metal or liquid medium.

[0087] In this embodiment, if Figure 1 As shown, the monitoring device is a dual-mode communication module, the first communication mode is wireless communication, and the second communication mode is hydroacoustic communication, that is, the second communication mode is to generate vibrations through the underwater part of the monitoring device to generate hydroacoustic waves and transmit communication signals through the hydroacoustic channel.

[0088] The monitoring device 110 broadcasts the first signal to the water surface area 110 through the wireless communication above the water surface, i.e., the first communication mode, and all the monitoring devices 120 that receive the first signal will suspend or turn off the channel quality detection of the second communication mode, i.e., the underwater acoustic communication, so that the monitoring device 110 will only receive the channel quality detection signal of the underwater acoustic channel of the monitoring device 130. This avoids the interference caused by the monitoring device 120 that does not need to perform underwater acoustic communication also sending the channel quality detection signal.

[0089] S202: Acquire data to be transmitted and a channel quality detection signal fed back by at least one second dual-mode communication module through a second communication mode.

[0090] In this step, the data to be transmitted includes control instructions. Since the at least one second dual-mode communication module cannot currently receive the first signal, it defaults to sending a channel quality detection signal through the second communication mode to detect and estimate the state of the channel used by the second communication mode.

[0091] S203: Use a preset adaptive adjustment model to adjust communication parameters of the second communication mode according to the channel quality detection signal.

[0092] In this step, the communication parameters include: signal output power, center frequency of the communication frequency band and sub-band, coding method, modulation method, etc.

[0093] In a possible design, the communication parameters include: modulation mode, that is, by presetting multiple sets of different modulation parameters or modulation models, different preset modulation modes are formed. In this way, the most suitable modulation mode can be quickly selected according to the channel state fed back by the channel quality detection signal, thereby improving the efficiency of signal processing.

[0094] Specifically, this step includes:

[0095] S2031. Determine a channel estimation result by using a preset channel estimation model according to a channel quality detection signal and an original signal corresponding to the channel quality detection signal.

[0096] In this step, the channel estimation results include: channel gain, phase, delay, the original signal is the output signal of the output end of the second dual-mode communication module, and the channel quality detection signal is the received signal obtained by the current receiving end after the original signal is transmitted through the channel.

[0097] In a possible design, the channel estimation result also includes: a channel cost function of the signal affected by the channel during transmission, and its calculation model is shown in formula (1):

[0098]

[0099] in, is the channel cost function, T is the channel quality detection signal, T0 is the original signal, is the conjugate transposed matrix of T0.

[0100] Optionally, the channel cost function includes: at least one of: bit error rate, signal-to-noise ratio, capacity, energy efficiency, and cost function:

[0101] 1. Bit Error Rate (BER): The channel cost function can be the bit error rate, which is the ratio of the number of bits judged as erroneous at the receiving end to the total number of transmitted bits. By minimizing the bit error rate, the reliability of the communication system can be improved.

[0102] 2. Signal-to-Noise Ratio (SNR): The channel cost function can be the signal-to-noise ratio, which is the ratio of signal power to noise power. Generally, it is hoped to improve the performance of the communication system by maximizing the signal-to-noise ratio.

[0103] 3. Capacity: The channel cost function can be the channel capacity, which is the maximum information rate that the channel can transmit under ideal conditions. By maximizing the channel capacity, a higher data transmission rate can be achieved.

[0104] 4. Energy Efficiency: The channel cost function can be energy efficiency, which is the energy consumed when transmitting a certain amount of data. By maximizing energy efficiency, it is possible to improve communication quality while reducing energy consumption.

[0105] 5. Cost Function: The channel cost function can also be a cost function, which takes into account various resource consumption in the communication system, such as power consumption, bandwidth utilization and other factors, so as to optimize the design overall.

[0106] In practical applications, choosing a suitable channel cost function is crucial to optimizing the performance of communication systems. Different channel cost functions will lead to different system designs and tuning strategies. Therefore, the characteristics of the channel and the applicable cost function need to be carefully considered in the design of communication systems.

[0107] In this embodiment, the signal-to-noise ratio may be selected as the channel cost function. There are three types of signal-to-noise ratios: input signal-to-noise ratio, pilot signal-to-noise ratio, and effective signal-to-noise ratio.

[0108] The calculation formula of input signal-to-noise ratio is shown in formula (2):

[0109]

[0110] Among them, E IS is the input signal-to-noise ratio, T(i) is the channel quality detection signal, Nose(i) is the noise signal, that is, the difference between the original signal and the channel quality detection signal, and E represents the signal energy or signal power.

[0111] For underwater acoustic communication, the calculation of input signal-to-noise ratio is performed after the signal is received and before various processing. It cannot reflect the possible inter-subcarrier interference caused by Doppler frequency shift, and cannot well reflect the actual performance of the signal in the underwater acoustic channel.

[0112] The pilot signal-to-noise ratio is an indicator in the frequency domain, and its calculation formula is shown in formula (3):

[0113]

[0114] Among them, E PS is the pilot signal-to-noise ratio, p(i) is the pilot subcarrier of the channel quality detection signal, n(i) is the noise signal, i.e., the null subcarrier, and E represents the signal energy or signal power.

[0115] The pilot signal-to-noise ratio is a measurement indicator in the frequency domain. It uses the energy at the empty subcarrier in the OFM signal as noise and the energy at the pilot as signal energy. This calculation occurs after the fast Fourier transform. Although the pilot signal-to-noise ratio includes possible inter-subcarrier interference, its calculation process is before channel estimation. When the multipath phenomenon is not obvious, this indicator will be more accurate. When there are many propagation paths, such as many refraction paths in water during underwater acoustic communication, the impact is greater. Because it ignores the impact of the channel on the communication system.

[0116] The effective signal-to-noise ratio is also an indicator in the frequency domain, and its calculation formula is shown in formula (4):

[0117]

[0118] Among them, E S is the value of the effective signal-to-noise ratio, is the frequency domain value of the channel cost function, T0(i) is the frequency domain signal corresponding to the original signal on each subcarrier, T(i) is the frequency domain signal corresponding to the channel quality detection signal on each subcarrier, and E represents signal energy or signal power.

[0119] The effective signal-to-noise ratio not only includes environmental noise, possible inter-symbol interference, and inter-subcarrier interference, but also includes the error of channel estimation. Therefore, from a theoretical analysis point of view, the effective signal-to-noise ratio is more valuable for channel estimation.

[0120] S2032. Determine at least one target modulation mode from a plurality of preset modulation modes according to the channel estimation result and the signal modulation mode mapping table.

[0121] In this step, the corresponding target modulation mode is searched for each channel sub-band transmitting the mechanical wave signal in the signal modulation mode mapping table according to the channel estimation result.

[0122] In a possible design, this step specifically includes:

[0123] The effective signal-to-noise ratio formula is used to calculate the value of the effective signal-to-noise ratio according to the frequency domain value of the channel cost function, the channel quality detection signal and the frequency domain signal corresponding to the original signal on each subcarrier;

[0124] When the value of the effective signal-to-noise ratio is greater than or equal to the first mode selection threshold and less than the second mode selection threshold, the target modulation mode is the first phase shift keying modulation;

[0125] When the value of the effective signal-to-noise ratio is greater than or equal to the second mode selection threshold and less than the third mode selection threshold, the target modulation mode is the second phase shift keying modulation;

[0126] When the value of the effective signal-to-noise ratio is greater than or equal to the third mode selection threshold, the target modulation mode is the third phase shift keying modulation;

[0127] The number of first states corresponding to the first phase shift keying modulation is half the number of second states corresponding to the second phase shift keying modulation, and the number of third states corresponding to the third phase shift keying modulation is twice the number of second states.

[0128] In this embodiment, the first phase shift keying modulation is binary phase shift keying BPSK (Binary Phase ShiftKeying), the second phase shift keying modulation is quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK), and the third phase shift keying modulation is 8 phase shift keying 8PSK (8Phase Shift Keying).

[0129] For example, when the effective signal-to-noise ratio is between 0.98 and 4.06 dB, binary phase shift keying BPSK is used for modulation; when the effective signal-to-noise ratio is between 4.06 and 8.03 dB, quadrature phase shift keying QPSK is used for modulation; and when the effective signal-to-noise ratio is greater than 8.03 dB, 8PSK is used for modulation.

[0130] S204: Adaptively encode and modulate the data to be transmitted using the adjusted second communication mode to obtain an output signal.

[0131] In this step, first, a bit distributor is used to divide the data to be transmitted into multiple sequences to be transmitted, each sequence to be transmitted corresponds to a transmission sub-band, and the channel corresponding to the second communication mode includes multiple transmission sub-bands; then, according to the target modulation mode corresponding to each transmission sub-band determined in S203, each sequence to be transmitted is modulated to obtain multiple modulated signals; finally, after inserting a pilot symbol into each modulated signal, an output signal is obtained after fast Fourier transform modulation processing.

[0132] The specific method of generating the output signal of this step refers to the underwater acoustic communication method and will not be elaborated here.

[0133] S205: Transmit the output signal to at least one second dual-mode communication module through a communication channel corresponding to the second communication mode.

[0134] In this embodiment, if Figure 1As shown, the second communication mode is underwater acoustic communication, which transmits the output signal through the underwater acoustic communication channel without artificially laying communication lines.
