[0040] At least two signal links are formed between the acquisition module 110, the high-speed acquisition module 120, the isolation module 130, the network switch 140, and the control module 150, so that different signal links acquire and process different signals.
[0041] Specifically, a signal link is formed between the acquisition module 110, the high-speed acquisition module 120, the network switch 140, and the control module 150;
[0042] A signal link is formed between the acquisition module 110, the isolation module 130, the high-speed acquisition module 120, the network switch 140, and the control module 150.
[0043] The aforementioned networks include, but are not limited to, at least one of the following: wired networks and wireless networks.

[0044] The network used for communication between the network switch 140 and the high-speed acquisition module 120, and the network used for communication between the network switch 140 and the control module 150, can be the same or different.
[0045] In the actual use of the signal acquisition and processing device 100, users can select the corresponding hardware modules according to their actual needs to form the corresponding signal links, so as to meet the required electrical signal acquisition needs and realize the modular design of the signal links.
[0046] In each signal link, each hardware module is only responsible for one function in the signal acquisition task. At the same time, there is no strong coupling between the functions of each hardware module. Users can flexibly adjust and select hardware modules according to the actual acquisition and monitoring needs of the hybrid power system to achieve modular hardware design.
[0047] Understandably, this application forms different signal links between multiple hardware modules in the signal acquisition and processing device 100, so that different signals are acquired and processed through different signal links. This modular design of the signal acquisition and processing device 100 meets the acquisition requirements of all types of electrical signals in the hybrid power system, greatly improving the applicability, scalability and signal processing capability of the signal acquisition and processing device, while also improving the convenience of product troubleshooting and maintenance.
[0048] In the embodiments of this application, the signal acquisition and processing device 100 further includes: a frequency multiplier module 160, which is used to adjust the signal frequency, and the frequency multiplier module 160 is electrically or wirelessly connected to the high-frequency acquisition module 120 and the isolation module 130 respectively.
[0049] In one specific embodiment of this application, the isolation module 130 is wirelessly or electrically connected to the high-speed acquisition module 120 via the frequency multiplier module 160, thereby forming a signal link among the acquisition module 110, the isolation module 130, the frequency multiplier module 160, the high-speed acquisition module 120, the network switch 140, and the control module 150; in another specific embodiment of this application, the isolation module 130 is directly wirelessly or electrically connected to the high-speed acquisition module 120, thereby forming a signal link among the acquisition module 110, the isolation module 130, the high-speed acquisition module 120, the network switch 140, and the control module 150.
[0050] In embodiments of this application, the acquisition module 110 includes: a first acquisition unit 111, which is used to acquire at least the vibration acceleration signal and the eddy current signal of the hybrid power system, and the first acquisition unit 111 is wirelessly or electrically connected to the high-speed acquisition module 120; a second acquisition unit 112, which is used to acquire at least the top dead center signal, the cylinder pressure signal and the speed signal of the hybrid power system, and the second acquisition unit 112 is wirelessly or electrically connected to the isolation module 130; and a third acquisition unit 113, which is used to acquire at least the magnetoelectric periodic signal of the hybrid power system, and the third acquisition unit 113 is wirelessly or electrically connected to the isolation module 130.
[0051] The terms "first", "second", and "third" in the first acquisition unit 111, the second acquisition unit 112, and the third acquisition unit 113 are only used to distinguish different acquisition units in the acquisition module 110, and are not a limitation on the number or order of acquisition units.
[0052] The first acquisition unit 111, the second acquisition unit 112, and the third acquisition unit 113 can be signal acquisition sensors to acquire different signals in the hybrid power system.
[0053] In the embodiments of this application, the isolation module 130 includes a conversion unit (not shown) and an identification unit (not shown). The conversion unit is used to convert signals, and the identification unit is used to identify different signals, so that the isolation module 130 can perform different processing on different signals.
[0054] Furthermore, a first signal link is formed between the first acquisition unit 111, the high-speed acquisition module 120, the network switch 140, and the control module 150;
[0055] Specifically, the vibration acceleration signal, eddy current signal, and other signals in the hybrid power system that meet the acquisition requirements of the high-speed acquisition module 120 are acquired by the first acquisition unit 111 and transmitted to the high-speed acquisition module 120. After being transmitted through the high-speed acquisition module 120 and the network switch 140, they are transmitted to the control module 150. The control module 150 analyzes and processes the signals to realize the status monitoring, fault diagnosis and auxiliary decision-making of the hybrid power system.
[0056] A second signal link is formed between the second acquisition unit 112, the isolation module 130, the high acquisition module 120, the network switch 140, and the control module 150;
[0057] Specifically, signals in the hybrid power system that do not meet the acquisition requirements of the high-speed acquisition module 120, such as the top dead center signal, cylinder pressure signal, and speed signal, are acquired by the second acquisition unit 112 and transmitted to the isolation module 130. After the identification unit in the isolation module 130 identifies the signal, the isolation module 130 transmits the signal to the high-speed acquisition module 120. After passing through the high-speed acquisition module 120 and the network switch 140, the signal is transmitted to the control module 150. The control module 150 analyzes and processes the signal to achieve hybrid power system status monitoring, fault diagnosis, and auxiliary decision-making.
[0058] A third signal link is formed between the third acquisition unit 113, the isolation module 130, the frequency multiplier module 160, the high-speed acquisition module 120, the network switch 140, and the control module 150.
[0059] Specifically, the magneto-electric periodic signal in the hybrid power system is acquired by the third acquisition unit 113 and transmitted to the isolation module 130. The identification unit in the isolation module 130 identifies the magneto-electric periodic signal, and the conversion unit in the isolation module 130 converts the magneto-electric periodic signal into a pulse square wave signal. The isolation module 130 transmits the pulse square wave signal to the frequency multiplier module 160, which adjusts the frequency of the pulse square wave signal. The adjusted pulse square wave signal is then transmitted by the frequency multiplier module 160 to the high-frequency acquisition module 120, and then transmitted through the high-frequency acquisition module 120 and the network switch 140 to the control module 150. The control module 150 analyzes and processes the signal to achieve state monitoring, fault diagnosis, and auxiliary decision-making for the hybrid power system.
[0060] In the embodiments of this application, the magnetoelectric periodic signal is processed by the third acquisition unit 113, the isolation module 130, and the frequency multiplication module 160 and then enters the high-sampling module 120. It can be used as a trigger level or a clock to achieve sampling mode adjustment.
[0061] Furthermore, this application can adjust the sampling trigger mode or sampling clock by adjusting the parameters of the isolation module 130 and the frequency multiplier module 160 to adjust the pulse square wave signal.
[0062] Specifically, this application can convert the magneto-electric periodic signal into different pulse square wave signals by adjusting the isolation module 130, and adjust the frequency of the pulse square wave signal by adjusting the frequency multiplication module 160, so that the pulse square wave signal can be used as a trigger level or the clock after entering the high sampling module 120, thereby realizing the adjustment of the sampling trigger mode or the sampling clock, and finally realizing the sampling mode adjustment.
[0063] In this application, the sampling mode of the signal acquisition and processing device 100 is designed to be adjustable, so that the signal acquisition and processing device 100 can meet the needs of both normal mode sampling and special working condition sampling, which greatly expands the application scenarios of the product.
[0064] In the embodiments of this application, the acquisition module 110 further includes: a fourth acquisition unit 114, which is used at least to acquire the temperature signal and pressure signal of the hybrid power system;
[0065] The signal acquisition and processing device 100 further includes a low-level acquisition module 170 and an edge computing gateway 180. The low-level acquisition module 170 is electrically or wirelessly connected to the fourth acquisition unit 114; and the low-level acquisition module 170 is network-connected to the edge computing gateway 180, which is also network-connected to the control module 150.
[0066] A fourth signal link is formed between the fourth acquisition unit 114, the low-frequency acquisition module 170, the edge computing gateway 180, and the control module 150.
[0067] The "fourth" in the fourth acquisition unit 114 is only to distinguish the different acquisition units in the acquisition module 110, and it is not a limitation on the number or order of acquisition units.
[0068] The fourth acquisition unit 114 can be a signal acquisition sensor to acquire signals from the hybrid power system.
[0069] Understandably, low-level signals such as temperature and pressure in the hybrid power system are collected by the fourth acquisition unit 114 and transmitted to the low-level acquisition module 170. After being transmitted to the edge computing gateway 180, the signals are parsed by the edge computing gateway 180 and transmitted to the control module 150. The control module 150 analyzes and processes the signals to achieve hybrid power system status monitoring, fault diagnosis, and auxiliary decision-making.
[0070] The signal acquisition and processing device 100 in this application employs an edge computing gateway 180 in the signal link to receive and parse low-sampling signals from the hybrid power system in real time, reducing data latency. At the same time, the container management function of the edge computing gateway can be used to realize the rapid adjustment and deployment of the acquisition program, enabling distributed processing of low-sampling signals. This significantly reduces the operating pressure on control modules such as industrial control computers and improves the reliability of the signal acquisition and processing device.
[0071] In the embodiments of this application, the control module 150 includes: a terminal 151 and an industrial control computer 152, and the network switch 140 is connected to the terminal 151 and the industrial control computer 152 via a network.
[0072] The signal can be processed by the terminal 151 or the industrial control computer 152 alone, or by the terminal 151 and the industrial control computer 152 together.
[0073] In the embodiments of this application, the terminal 151 can be any one of a PC, a mobile phone, or a tablet computer.
[0074] For example, terminal 151 can be a PC; or it can be a mobile phone; or it can be a tablet computer. Users can configure the specific terminal 151 according to their actual needs.
[0075] In the embodiments of this application, the signal acquisition and processing device 100 further includes a power module 190, which is electrically connected to the high acquisition module 120, the isolation module 130, the network switch 140, the control module 150, the frequency multiplier module 160, the low acquisition module 170, and the edge computing gateway 180.
[0076] The power module 190 can be either an energy storage battery or a power generation device.
[0077] In this application, a power supply module 190 is provided in the signal acquisition and processing device 100 to ensure the normal operation of each hardware module in the signal acquisition and processing device 100.
