[0033] In one exemplary embodiment, such as Figure 1 As shown, a communication device is provided, including a computing display module 100, a network switching module 200, and an interface expansion module 300. The computing display module 100 and the network switching module 200 are both fixed to the interface expansion module 300, and the interface expansion module 300 has at least one peripheral serial port interface, one peripheral Ethernet interface, and one peripheral CAN interface. The computing display module 100 and the network switching module 200 are connected through the interface expansion module 300. The communication device is connected to an environmental monitoring device through the peripheral serial port interface, to a network monitoring device through the peripheral Ethernet interface, and to a production device through the peripheral CAN interface.

[0034] In this application, both the computing display module 100 and the network switching module 200 are fixed to the interface expansion module 300, and both can be connected to the interface expansion module 300, thereby achieving an indirect connection between the computing display module 100 and the network switching module 200. After the computing display module 100 and the network switching module 200 are fixedly connected to the interface expansion module 300, at least one peripheral interface can be brought out through the interface expansion module 300 to achieve combined use with various external devices and equipment. It can be understood that the computing display module 100, the network switching module 200, and the interface expansion module 300 are modularly designed, with each module being independently designed and capable of being combined and installed into a complete communication device. This modular design makes it easier to upgrade and replace modules and maintain them during use.

[0035] Specifically, the computing and display module 100 is used to realize functions such as environmental monitoring and production line control in the manufacturing field. The computing and display module 100 can integrate data processing algorithms to collect various types of data in the manufacturing field and monitor the production line in real time based on the collected data, ensuring normal production operation and protecting equipment and personnel safety. Simultaneously, combined with the network switching module 200, it integrates high-performance Ethernet data exchange functions for data interaction and transmission. Furthermore, network management adopts a visual web interface design, facilitating the use of various communication peripherals and the management and monitoring of network devices.

[0036] Furthermore, the computing display module 100 and the network switching module 200 can bring out at least a variety of interfaces, such as peripheral serial port interface, peripheral Ethernet interface and peripheral CAN interface, through the interface expansion module to connect to various peripheral devices in the production and manufacturing system for data interaction. Based on the characteristics of controllable high-resolution graphics display interface, low power consumption and high-speed data processing, environmental monitoring and production line control of large-scale production and manufacturing systems can be realized.

[0037] For example, the computing and display module 100 can be connected to an environmental monitoring device via an external serial port interface to acquire various environmental data in the production environment, and analyze and process the data to detect the comfort level and abnormal conditions of the production environment, thus preventing situations that could endanger the lives of personnel in the production environment. The computing and display module 100 can also be connected to the production device via an external CAN interface to obtain the current production status of the production device and further output control commands to control the normal operation of the production process. The network switching module 200 can also be connected to a network monitoring device via an external Ethernet interface to obtain high-definition real-time monitoring images through the network monitoring device, thereby achieving safety monitoring of the production line.

[0038] The aforementioned communication equipment includes a computing and display module, a network switching module, and an interface expansion module. Both the computing and display module and the network switching module are fixed to the interface expansion module. Communication between the computing and display module and the network switching module is achieved through the interface expansion module. The interface expansion module provides at least three external interfaces: a serial port, an Ethernet port, and a CAN port. The communication equipment connects to the environmental monitoring device in the system via the serial port, to the network monitoring device via the Ethernet port, and to the production device via the CAN port. This enables data interaction with various devices within the system. For increasingly complex scenarios and large-scale system applications, this equipment can meet the network communication and interaction needs between multiple devices.

[0039] In one exemplary embodiment, such as Figure 2 As shown, the interface expansion module 300 is provided with a first COME interface device 310 and a second COME interface device 320; wherein, the calculation and display module 100 is fixedly connected to the interface expansion module 300 through the first COME interface device 310, and the network switching module 200 is fixedly connected to the interface expansion module 300 through the second COME interface device 320.

[0040] Specifically, this application uses a COME connector as an interface device to achieve modular connection of various modules. The COME connector is a connector used to connect circuit boards to each other and to components in electronic devices, enabling connection and signal transmission between circuits. This application specifically uses a board-to-board type COME connector, which not only has high transmission speed but also good durability and stability, ensuring connection reliability and effectively guaranteeing signal quality, thereby achieving product quality reliability.

[0041] The computing display module 100 can be fixed to the interface expansion module 300 via the first COME interface device 310, and the signal transmission is achieved through the connection between the first COME interface device 310 and the interface expansion module 300. Similarly, the network switching module 200 can be fixed to the interface expansion module 300 via the second COME interface device 320, and the signal transmission is achieved through the connection between the second COME interface device 320 and the interface expansion module 300.

[0042] It is understood that the positions of the computing display module 100 and the network switching module 200 fixed on the interface expansion module 300 are not limited and can be determined according to the actual product size and signal line requirements. For example, in this embodiment, the computing display module 100 can be fixed to the heat dissipation surface of the interface expansion module 300. The heat dissipation surface of the interface expansion module 300 is the outer surface of the interface expansion module 300 where heat dissipation components are provided. Since the computing display module 100 needs to perform data processing tasks, it needs effective heat dissipation to ensure the stable operation of the communication equipment. For example... Figure 2 As shown, a heat dissipation component is provided on the inner side of the bottom surface of the interface expansion module 300, which allows the computing display module 100 to be fixed to the bottom surface of the interface expansion module 300 via the first COME interface device 310. Meanwhile, for the convenience of signal line setup, the network switching module 200 is fixed to the top surface of the interface expansion module 300 via the second COME interface device 320.

[0043] In one exemplary embodiment, such as Figure 3 As shown, the computing and display module 100 includes an interconnected central processing unit 110 and a graphics processing unit 120. The computing and display module 100 also includes a storage component and a signal conversion component. Both the central processing unit 110 and the graphics processing unit 120 are connected to the storage component. The central processing unit 110 has a first MDI Ethernet port, a GPIO interface, a UART interface and a CAN interface connected to the first COME interface device 310 through the signal conversion component. The central processing unit 110 also has a PCIE interface directly connected to it. The graphics processing unit 120 has a DP display interface and a USB interface directly connected to the first COME interface device 310.

[0044] Specifically, the central processing unit 110 is used to process data related to the operation of communication equipment and can be connected to the network switching module 200 through the interface expansion module 300. The graphics processing unit 120 is mainly used to process data related to environmental monitoring and production line control, such as using data processing algorithms to analyze various environmental data to obtain the production environment status, and outputting control commands based on the current production status to control the normal operation of the production process. The central processing unit 110 and the graphics processing unit 120 can also communicate bidirectionally; the central processing unit 110 can send data that needs to be processed and analyzed to the graphics processing unit 120, and the graphics processing unit 120 can provide feedback on its own working status to the central processing unit 110. It is understood that the functions of the central processing unit 110 and the graphics processing unit 120 described above are merely illustrative examples. Those skilled in the art can extend the functionality according to the corresponding types of interfaces. Any function that can be accomplished using chips and interfaces similar to those described in this application falls within the scope of protection of this application.

[0045] Furthermore, the computing display module 100 can provide various types of interfaces to the interface expansion module 300. These interfaces can include communication interfaces, such as MDI Ethernet ports, GPIO interfaces, UART interfaces, USB interfaces, and CAN interfaces, as well as display interfaces, such as DP display interfaces. It can be understood that the interfaces provided by the computing display module 100 can be used for data transmission between the computing display module 100 and the network switching module 200 (e.g., MDI Ethernet ports), or they can be output by the interface expansion module 300 as peripheral interfaces for connecting external devices (e.g., other communication interfaces and display interfaces).

[0046] Correspondingly, the central processing unit 110 and the graphics processing unit 120 can directly or indirectly expose at least one type of interface as various interfaces from the computing display module 100 to the interface expansion module 300. Indirect exposure can be achieved using a signal conversion component. This can be understood as the signal conversion component converting and processing the data output from the interface between the central processing unit 110 and the graphics processing unit 120 before outputting it to the first COME interface device 310, and further transmitting it via the interface expansion module 300 to the network switching module 200 and external devices.

[0047] Among them, the first MDI Ethernet port, GPIO interface, UART interface and CAN interface can be output after being converted by the signal conversion component after being brought out from the central processing unit 110, while the PCIe interface can be brought out directly from the central processing unit 110, and the DP display interface and USB interface can be brought out directly from the graphics processor 120.

[0048] For example, the number of the various types of interfaces derived from the central processing unit 110 and the graphics processor 120 is not fixed. For example, in this embodiment, the interfaces may include, but are not limited to: 2 first MDI Ethernet ports, 8 GPIO interfaces, 2 UART interfaces, 2 CAN interfaces, 1 PCIe interface, 2 DP display interfaces and 2 USB interfaces.

[0049] In one exemplary embodiment, please continue to refer to Figure 3 The signal conversion components include a network transceiver and a level conversion chip; the RGMII interface of the central processing unit 110 is converted into a first MDI Ethernet port through the network transceiver, and the GPIO interface, UART interface and CAN interface of the central processing unit 110 are level converted through the level conversion chip.

[0050] The network transceiver uses the YT8521 chip from Yutai Automotive Technology Co., Ltd., which can convert one RGMII or SGMII interface from the MAC type interface into an MDI interface. It integrates a SerDes transceiver and can also be configured as a SerDes interface, supporting 10 / 100 / 1000M Ethernet data rates. The level conversion chip is implemented using a Complex Programmable Logic Device (CPLD) chip. Alternatively, the GW1N-LV4PG256C6 / I5 chip from Guangdong Gaoyun can be used. This chip has abundant logic resources, supports multiple I / O level standards, and embeds block static random access memory, digital signal processing modules, and phase-locked loop resources. It features low power consumption, instant start-up, low cost, high security, small product size, various package types, and convenient and flexible use. The GW1N-LV4PG256C6 / I5 chip contains 4608 logic units, 180K memory blocks, 2 PLL phase-locked loops, 4 I / O banks, supports a maximum of 218 I / O pins, and has a core power voltage of 1.2V.

[0051] Specifically, the signals from the two Gigabit Ethernet interfaces (RGMII) of the central processing unit 110 are converted into a first MDI Ethernet port via the YT8521 chip to establish one communication connection with the network switching module 200, and the other is expanded into a peripheral MDI Ethernet port via the interface expansion module 300 to connect with peripheral network switching devices. The central processing unit 110 connects to the CPLD chip through its 8 GPIO interfaces, 2 UART interfaces, and 2 CAN interfaces. The CPLD chip performs level conversion on the signals output from the above interfaces of the central processing unit 110 and outputs them through the interface expansion module 300 to connect to peripheral devices.

[0052] In addition, the CPLD chip is also used for the power-on and reset functions of communication equipment. The CPLD chip is connected to the control part of the communication equipment, receives the power-on and reset signals, and feeds the power-on and reset signals back to the reset terminal of the central processing unit 110 to realize the power-on and reset control of the communication equipment.

[0053] In one exemplary embodiment, please continue to refer to Figure 3 The central processing unit 110 is a D2000-8 core processor, and the graphics processing unit 120 is a Phytium X100 chipset.

[0054] The central processing unit 110 uses the Tengrui D2000-8 high-performance general-purpose processor. It integrates eight 64-bit FTC663 high-performance cores with a main frequency of 2.0GHz and an operating temperature range of -40~105°C; it has a built-in cryptographic acceleration engine and integrates system-level security mechanisms. Compatible with ARM v8 architecture and virtualization architecture, supporting 64-bit and 32-bit instruction modes, and supporting mainstream KVM and Xen virtual machines; supports single-precision and double-precision floating-point instructions; supports ASIMD processing instructions; integrates 8MB L2 cache and 4MB L3 cache; two DDR4-3200 channels, supporting real-time encryption of DDR storage data; integrates 34-lane PCIe 3.0 interfaces: two x16 (each can be split into two x8), two x1; integrates two Gigabit Ethernet interfaces (RGMII), supporting 10 / 100 / 1000Mbps auto-negotiation; integrates one SD card controller, compatible with SD 2.0 specification; integrates one HDA (HD-Audio), supporting audio output, and can support up to four codecs simultaneously; integrates symmetric, asymmetric, and promiscuous cryptography acceleration engines; integrates four UARTs and one LPC. Master, 32 GPIOs, 4 I2Cs, 1 QSPI, 2 general purpose SPIs, 2 WDTs, 16 external interrupts; integrated with 2 temperature sensors and 128KB on-chip memory.

[0055] The graphics processor 120 uses the Phytium X100 chipset. It integrates one low-power GPU chip with a clock speed of 800MHz, a peak single-precision floating-point computing power of 400GFLOPS, a maximum pixel fill rate of 6.4 GPixel / s, and a maximum texture fill rate of 12.8 GTexture / s; it also integrates one VideoDecoder, supporting 4K@30fps decoding and mainstream encoding formats such as H.264 / 265, MPEG4, MPEG2, and JPEG; it integrates three DisplayPort 1.4 display interfaces, with two supporting a maximum resolution of 3840x2160@60Hz and one supporting a maximum resolution of 1920x1080@60Hz; it integrates one 64-bit DDR4 / LPDDR4 memory controller, supporting up to 8GB of memory with a maximum speed of 3200MT / s and a peak bandwidth of 25.6GB / s; and it integrates one x16 PCIe 3.0 uplink interface and eight PCIe... The system features a 3.0 downlink interface, including 2 x2 and 6 x1 ports, with two x1 ports multiplexed with SATA 3.0 interfaces; integrated 4 SATA 3.0 interfaces; 8 independent USB 3.1 Gen 1 interfaces; integrated 2 SD / SDIO / eMMC controllers supporting SD 3.0, SDIO 3.0, and eMMC 5.0 protocol specifications; integrated 1 NandFlash controller supporting the ONFI 2.2 protocol; and integrated 4 UARTs, 1 LPC Master, 96 GPIOs, 8 MIOs (configurable to UART, I2C, and PWM modes), 4 PWMs, 1 QSPI, 2 general-purpose SPI Masters, 3 SMBus controllers, and 2 CAN controllers.

[0056] Specifically, the Phytium X100 chipset communicates with the D2000-8 core processor via its integrated x16 PCIe 3.0 uplink interface, uploading information such as its operating status, interface communication status, and internal temperature to the D2000-8 core processor through this uplink. The D2000-8 core processor can perform periodic self-tests and report its own and the Phytium X100 chipset's information to the upper-level communication center, realizing the BIT (Build-In-Test) function. Since the communication interface supports a theoretical bandwidth of nearly 8GB / s, the entire computing and display module 100 operates very smoothly in system operation, data processing, and interface display.

[0057] In this embodiment, by using a combination of domestically produced high-performance, low-power CPU and GPU, 100% domestic production can be achieved, and the communication equipment as a whole can achieve high performance while keeping power consumption low.

[0058] In one exemplary embodiment, please continue to refer to Figure 3The storage components include a memory controller, a video memory controller, and a system storage disk. The memory controller is connected to the central processing unit 110, and the video memory controller and the system storage disk are both connected to the graphics processor 120.

[0059] Specifically, the memory controller uses Changxin Memory's DDR4 surface-mount chip CXDQ3A8AM-WG, a 64Gbit LPDDR4 memory controller with a maximum operating speed of 2666Mbps, a power supply voltage of 1.2V, and a maximum voltage of 2.5V. The D2000-8-core processor can connect 16 CXDQ3A8AM-WG chips through one internal DDR4 controller to achieve 16GB of memory. The graphics memory controller is a 64-bit DDR4 / LPDDR4 memory controller, using Changxin Memory's LPDDR4 surface-mount chip CXDB5CCAM-MK, with a +1.1V power supply, 32-bit data bits, and a maximum data rate supporting 3200Mbps. The Phytium X100 chipset's 64-bit DDR / LPDDR4 graphics memory controller can achieve 8GB of graphics memory by connecting two external chips. The Phytium X100 chipset also connects a system storage drive through its one SATA 3.0 interface, including... Figure 3 As shown, the system storage disk can be a solid-state drive with a storage capacity of 128G.

[0060] In this embodiment, the storage component provides the computing and display module 100 with 16GB of system memory and 8GB of system video memory, which means it has a powerful data cache space. In addition, the mounted 128GB system storage disk supports expansion space, providing the module with a sufficiently large data storage space.

[0061] In one exemplary embodiment, such as Figure 4 As shown, the network switching module 200 includes an interactive processor 210 and an interactive memory controller. The interactive processor 210 is connected to the interactive memory controller, and the interactive processor 210 has a second MDI Ethernet port, a UART interface and a CAN interface leading to the second COME interface device 320.

[0062] Specifically, the interactive processor 210, through a visual web interface design, enables the use of various communication peripherals and the management and monitoring of network devices. The interactive processor 210 can communicate with the central processing unit 110 via the interface expansion module 300, thereby enabling the feedback and aggregation of all data analysis results processed by the graphics processor 120 to the communication center, providing accurate signals to production technicians and completing automated production control tasks.

[0063] For example, please continue to refer to Figure 4The interactive processor 210 uses the FSL91030M Ethernet switching chip. Specifically, the interactive processor 210 uses the FSL91030M Ethernet switching chip from Wuhan Freescale Technology Co., Ltd., which is a 32G bandwidth Layer 2 Ethernet switching chip with a main frequency of 400MHz. It supports 10 / 100 / 1000BASE-T and 100BASE-FX functions; it supports 8 / 16bits DDR3 with a maximum speed of 1066MHz; it supports complete Layer 2 network protocol processing functions; and it supports remote configuration. The network switching module 200, implemented using the FSL91030M Ethernet switching chip, has a visual network switch configuration management interface. The interface is built into the network switching module 200 and can be accessed simply by logging in at the specified address.

[0064] It is understood that the FSL91030M Ethernet switching chip has a second MDI Ethernet port, a UART interface, and a CAN interface leading to the second COME interface device 320. The UART interface and CAN interface can be output after signal type conversion for use in connecting peripheral devices. One of the MDI Ethernet ports is used as the second MDI Ethernet port to achieve communication connection with the central processing unit 110 through the interface expansion module 300.

[0065] Furthermore, the interactive memory controller can also be a DDR4 board-mount chip from Changxin Memory, CXDQ3A8AM-WG, which uses a DDR3 controller inside the FSL91030M Ethernet switching chip to mount a DDR4 chip to achieve 1GB of memory.

[0066] In one exemplary embodiment, such as Figure 3-5 As shown, the interface expansion module 300 also includes a power conversion unit 330 and a power protection unit. The computing display module 100 and the network switching module 200 also include an internal power supply unit. The internal power supply unit has a power supply interface leading to the COME interface device. The interface expansion module 300 also has a power peripheral interface. The input side of the power conversion unit 330 is connected to the power peripheral interface, and the output side is connected to the power supply interface through the power protection unit.

[0067] Specifically, the interface expansion module 300 can connect to an external power supply device via a power peripheral interface to obtain a power supply voltage of 18V-36V. The power conversion unit 330 can step down the 18V-36V power supply voltage input to its input side to obtain a 12V power supply voltage, which is then output to the internal power supply units of the computing display module 100 and the network switching module 200 through the power supply interface, thereby providing power to the computing display module 100 and the network switching module 200.

[0068] Furthermore, the power supply voltage converted by the power conversion unit 330 can be output to the internal power supply units of the computing display module 100 and the network switching module 200 after being protected by the power supply protection unit. This ensures the safety of the communication equipment, extends its service life, avoids the impact of voltage fluctuations on the overall operation of the communication equipment, and also ensures stable network communication between multiple peripheral devices. For example, such as... Figure 5 As shown, the power supply protection unit may include fuses, filters, power isolation components, and ESD protection components.

[0069] In one exemplary embodiment, such as Figure 5 As shown, the interface expansion module 300 also includes a signal transceiver 340 and a power management unit 350. The peripheral serial port interfaces brought out by the interface expansion module 300 include an RS485 peripheral interface, an RS232 peripheral interface, and an RS422 peripheral interface. The interface expansion module also brings out a CAN peripheral interface. Among them, the RS485 peripheral interface, RS232 peripheral interface, and RS422 peripheral interface are brought out from the UART interface after conversion by the signal transceiver 340, and the CAN peripheral interface is brought out from the CAN interface after conversion by the signal transceiver 340. The input side of the power management unit 350 is connected to the power peripheral interface, and the output side brings out a peripheral device control interface. The control side is connected to the GPIO interface, and the first MDI Ethernet port is connected to the second MDI Ethernet port.

[0070] Specifically, the transceiver 340 is used to convert the UART interface to a serial peripheral interface. The UART interface can be derived from the computing display module 100 or from the network switching module 200. For example, as... Figure 5 As shown, the transceiver 340 can convert the interface types of the six UART interfaces from the computing display module 100 to obtain two RS485 peripheral interfaces, two RS232 peripheral interfaces, and two RS422 peripheral interfaces. Alternatively, the transceiver 340 can convert the interface types of the two UART interfaces from the network switching module 200 to obtain two RS485 peripheral interfaces. These peripheral serial interfaces can be used to connect various types of peripheral devices to achieve communication. The specific device type used in the transceiver 340 is not limited; any conversion chip capable of converting UART interface types to serial port types can be used.

[0071] Furthermore, the power management unit 350 can be used to control the on / off switching of the power supply circuit for peripheral devices to ensure the power safety of each peripheral device. The input side of the power management unit 350 is connected to the power peripheral interface to obtain an external power supply voltage of 18V-36V. The output side of the power management unit 310 has a peripheral device control interface, which can be used to connect various types of peripheral devices and supply power to the peripheral devices through the external power supply voltage flowing through the power management unit. The control side of the power management unit 350 is connected to the GPIO interface of the computing display module 100, and can be used to output power supply signals to control the on / off switching of the power supply circuit for peripheral devices.

[0072] The first MDI Ethernet port is connected to the second MDI Ethernet port, which can be used to realize the communication connection between the computing display module 100 and the network switching module 200. In this embodiment, both the first MDI Ethernet port and the second MDI Ethernet port can be two-way Gigabit Ethernet interfaces, which can serve as an important path for external devices to transmit data to the computing display module 100 through the network switching module 200. Their stable and efficient transmission signal quality is the key to the stable operation of the communication equipment provided in this application.

[0073] The following is Figure 5 The system block diagram shown illustrates the functions of the communication device provided in this application.

[0074] Specifically, the communication device includes a computing display module 100, a network switching module 200, and an interface expansion module 300. The computing display module 100 consists of a Phytium D2000-8 processor and an X100 graphics GPU processor, while the network switching module 200 consists of a Freescale FSL91030M domestically produced chip. These two modules, combined with the interface expansion module 300, form a highly integrated, high-performance communication device. It features high performance, a controllable high-resolution graphical display interface, low power consumption, and high-speed data processing, making it suitable for large-scale industrial automation and automatic control systems.

[0075] Furthermore, it adopts a wide-range DC18~36V input power supply, and the power input terminal has power filtering, power isolation, reverse connection protection, electrostatic discharge protection, EMC protection, and other measures. It uses optical MOS isolation relays and supports two controllable DC24V power outputs, which can power external loads while ensuring that each module operates independently without interference, thus improving safety. It adopts a multi-functional, multi-interface expansion design, featuring 6 external gigabit Ethernet ports for internal network interaction between the computing display module and the network switching module, 2 RS485 interfaces, 4 CAN interfaces, 2 RS422 interfaces, and 2 RS232 interfaces. This meets the requirements of industrial control fields for multi-device communication, long communication distance, high communication speed, strong electromagnetic interference resistance, resistance to high and low temperature environments, and stable and reliable interfaces.

[0076] The interface expansion module 300, based on the characteristics and functions of the computing display module 100 and the network switching module 200, sets up peripheral interfaces to suit practical applications, converting signals into standard communication interface outputs. Externally, it provides 6 gigabit Ethernet ports, 2 RS485 interfaces, 4 CAN interfaces, 2 RS422 interfaces, and 2 RS232 interfaces. The display interface supports DP1.4 / eDP1.3 configuration output. The power input terminal features power filtering, power isolation, reverse connection protection, electrostatic discharge protection, and EMC protection measures. It uses an optical MOS isolation relay and supports two controllable DC24V power outputs, allowing external loads to operate while ensuring that the power supplies for each module are independent and do not interfere with each other. Dimensions: Modules are connected via COME connectors. The overall dimensions of the connected modules are: 110±0.2mm × 110±0.2mm × 40±0.2mm; Weight: ≤320g (excluding structural components); Power supply: Supports +18V~+36V wide voltage input, typical input voltage: +24V; Power consumption: Typical power consumption 30W, peak power consumption less than 36W; Operating system: Kylin OS.

[0077] like Figure 6 As shown, the domestically produced communication equipment provided in this application can have the following application scenarios in the manufacturing industry. Specifically, the network camera connects to the network switching module 200 via a gigabit Ethernet interface to achieve high-definition, real-time monitoring of the production line; temperature and humidity sensors and gas detection sensors can collect real-time temperature and humidity, harmful gases, and smoke information from various points in the factory, which is then sent to the computing and display module 100 via an RS232 communication bus for data processing. This provides temperature and humidity information for important areas within the factory, thereby adjusting the operation of the air conditioning and ventilation system in real time. If abnormal levels of harmful gases in the air are detected and exceed a set threshold, corresponding audible and visual alarms are triggered. Production equipment is shut down via a CAN bus, thus ensuring the safety of factory equipment and the health and safety of workers.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
