[0026] Embodiment 1: As Figure 1 shown, a multi-channel spark host system, the system includes: a power supply and carrier communication module 100, a microcontroller unit 101, a touch screen 102, a probe interface 103,

[0027] a 485 communication module 104, a network port communication module 105, a relay output module 106, a storage module 107;

[0028] Among them, the power supply and carrier communication module 100 is respectively connected to the probe interface 103 and the microcontroller unit 101 for powering both; the power supply and carrier communication module 100 can adopt an integrated power management chip and a carrier communication chip, such as the TMDSPLCKIT-V4 carrier communication development kit of Texas Instruments. This module can provide a stable power output and support power line carrier communication at the same time;

[0029] The microcontroller unit 101 receives monitoring signals from the probe interface 103 through the power supply and carrier communication module 100; Microcontroller unit 101: uses a high-performance 32-bit microcontroller, such as the STM32F7 series of STMicroelectronics; this kind of microcontroller has high-speed processing capabilities and rich peripheral interfaces;

[0030] The microcontroller unit 101 is communicatively connected to the touch screen 102, the 485 communication module 104, the network port communication module 105, the relay output module 106 and the storage module 107.

[0031] In a possible implementation manner, the touch screen 102 can adopt a 7-inch TFT LCD capacitive touch screen with a resolution of 800x480; the probe interface 103 can be a multi-channel analog signal input interface, and each channel is equipped with a signal conditioning circuit and an ADC (analog-to-digital converter); the 485 communication module 104 uses a MAX485 chip to achieve RS-485 communication; the network port communication module 105 adopts a W5500 Ethernet controller chip to support 10 / 100Mbps network communication; the relay output module 106 uses a multi-channel solid-state relay, such as the G3VM series of Omron; the storage module 107 adopts a combined storage solution of a large-capacity SD card and an EEPROM.

[0032] In this embodiment, the power supply and carrier communication module 100 integrates power management and communication functions. It powers various parts of the system through the power line and simultaneously uses carrier technology to transmit data on the same power line. This design simplifies the system wiring and improves the installation efficiency and system reliability. The probe interface 103 is connected to different spark probes to collect spark signals. These signals are transmitted to the microcontroller unit 101 through the power supply and carrier communication module 100. The microcontroller performs real-time signal processing and analysis and can quickly detect abnormal spark conditions. The microcontroller unit 101, as the core of the system, processes the data from the probes. It stores the processing results in the storage module 107, which can be used for real-time display or long-term data analysis.

[0033] In addition, the system also integrates a 485 communication module 104 and an Ethernet communication module 105, which can facilitate data exchange with other industrial devices or network systems. This enhances the system's interoperability and remote monitoring capabilities. The relay output module 106 allows the system to perform real-time control operations based on the spark detection results, such as triggering an alarm or shutting down related devices. The touch screen 102 provides an intuitive human-machine interface, and operators can conveniently view the system status, configuration parameters, and query historical data.

[0034] Embodiment 2: As Figure 2 shown, the above system further includes:

[0035] Multiple relay modules 108 and an edge computing module 109;

[0036] Among them, the relay module 108 is connected to multiple probe interfaces 103;

[0037] The relay module 108 is respectively communicatively connected to the microcontroller unit 101 and the edge computing module 109, and is used to forward the monitoring signal to the microcontroller unit 101 or the edge computing module 109 for processing when the communication is blocked.

[0038] In a specific solution, multiple probe interfaces 103 are divided into multiple groups, and the probe interfaces 103 in each group are connected to one relay module 108.

[0039] Exemplarily, the relay module 108 uses a low-power microcontroller, such as the MSP430 series of Texas Instruments, and integrates a wireless communication module (such as ZigBee or LoRa) and a wired communication interface (such as RS-485).

[0040] The edge computing module 109 uses an embedded computing platform, such as NVIDIA Jetson Nano or Raspberry Pi4, equipped with an AI accelerator.

[0041] Probe interface 103 grouping: The probe interfaces are divided into multiple groups according to physical location or function, with 8 - 16 probe interfaces in each group.

[0042] There is a wired connection of RS - 485 between the relay module 108 and the probe interface 103; between the relay module 108 and the microcontroller unit 101, mainly ZigBee wireless communication is used, with a backup RS - 485 wired connection; between the relay module 108 and the edge computing module 109: Ethernet or Wi - Fi connection is used.

[0043] Multiple relay modules 108 are distributed in different areas, and each relay module is responsible for a group of probe interfaces 103. This distributed architecture can cover a larger monitoring range and improve the reliability of the system. Even if a certain relay module fails, it will only affect some probes rather than the entire system.

[0044] Between the relay module 108 and the microcontroller unit 101, mainly wireless communication is used, but a wired connection is reserved as a backup. This redundant design ensures that the system can still maintain communication when the wireless signal is interfered or fails.

[0045] In this embodiment, the edge computing module 109 has relatively strong computing power and can execute more complex data analysis and machine learning algorithms. It can quickly process a large amount of data locally and only transmit key information back to the central system, thus reducing the burden on the central processor and improving the system response speed.

[0046] Embodiment 3: In the solution of Embodiment 2, the communication connection method between the relay module 108 and the edge computing module 109 is a wired connection.

[0047] Specifically, the wired connection is selected from one or more of the following: Ethernet connection, serial communication connection, USB connection, fiber connection. The wired connection is more stable than the wireless connection, reducing the possibility of signal interference and packet loss. Especially when using Ethernet or fiber connection, high - speed data transmission can also be achieved.

[0048] Embodiment 4: Different from Embodiment 3, the communication connection method between the relay module 108 and the edge computing module 109 is a wireless connection.

[0049] Specifically, the wireless connection is selected from one or more of the following: Wi - Fi connection, Bluetooth connection, ZigBee connection, LoRa connection, NB - IoT connection, 5G connection. Adopting the wireless connection method, there is no need for wiring, which can greatly simplify the installation process and is especially suitable for complex or difficult - to - wire environments.

[0050] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
