[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that in the existing technology, a high-speed backplane is a high-speed data transmission bus used to connect various functional modules in electronic devices. Its core function is to realize high-speed and stable data interaction between modules, and it is a key infrastructure for signal transmission inside the device.

[0030] Core features and functions:

[0031] High-speed transmission capability: Supports high-bandwidth, low-latency data transmission (such as the 100M LVDS signal used between modules below), meeting the needs of scenarios with high real-time requirements;

[0032] Modular connection: Serving as the "traffic hub" within the device, it connects the backplane and daughterboards (such as protocol module units and IO signal units) to enable flexible combination and data interoperability of different functional modules;

[0033] High reliability: It needs to have characteristics such as anti-interference and low loss, and be suitable for stable operation in complex scenarios such as industrial environment and communication equipment.

[0034] like Figures 1 to 5 As shown, the IP67 protection level unit-type remote I / O module based on a high-speed backplane includes a base plate 1, a protocol module unit 2 that uses different fieldbus protocols, and multiple optional I / O signal units 3. The protocol module unit 2 and the I / O signal units 3 are all mounted on the base plate 1. The protocol module unit 2 and the optional I / O signal units 3 transmit data through a 100M LVDS signal, thereby ensuring the real-time performance of the signal.

[0035] In this embodiment, the IO module adapts to different PLC types by selecting different protocol module units 2, and the IO module adapts to different PLC types by selecting different IO signal units 3. Different IO signal units can receive different signal types. This modular IP67 module allows customers to match the IO signal types and number of points according to their actual needs, thereby better meeting their usage requirements.

[0036] In a preferred embodiment of this utility model, the base plate 1 includes a base plate body 11. One end of the surface of the base plate body 11 is provided with a power interface 12 and a grounding interface 13. A protocol module unit 2 is installed on one side of the surface above the base plate body 11, and several I / O signal units 3 are provided on the other side of the surface above the base plate body 11. A clearance groove 14 is provided on each side of the base plate body 11, and each clearance groove 14 has a base plate mounting hole. Several positioning slots 15 are provided at the locations where the I / O signal units 3 are installed on the base plate body 11. The positioning slots 15 provide precise positioning for the upper-level I / O signal units 3. The power interface 12 (or external power supply interface) provides external power input to the entire module system, meeting the stable power supply requirements under IP67 protection environments. The grounding interface 13 ensures the electromagnetic compatibility and equipment safety of the module in industrial environments through reliable grounding, and is particularly suitable for strong interference scenarios.

[0038] In a preferred embodiment of this utility model, the protocol module unit 2 includes a protocol module body 21, a display screen 23 is mounted on the surface of the protocol module body 21, two communication interfaces 22 are mounted on one side of the display screen 23, and several indicator lights 24 are provided on the other side of the display screen 23. In this embodiment, the communication interface 22 serves as a data interaction channel between the module and external devices (PLC / host computer) to realize remote communication and protocol conversion.

[0039] In a preferred embodiment of this utility model, the protocol module unit 2 includes a protocol module body 21. A display screen 23 is mounted on the surface of the protocol module body 21. Two communication interfaces 22 are mounted on one side of the display screen 23, and a power interface 25 and a bus interface 26 are mounted on the other side of the display screen 23. In this embodiment, the power interface 25 is a circular connector with an IP67 protective sealing cover, located in the edge area of ​​the protocol module unit 2, and adopts a waterproof connector structure. The power interface 25 serves as the core power supply channel for the module, providing a stable DC power supply (typically 24V industrial-grade power) to the protocol module unit 2, the IO signal unit 3, and the high-speed backplane. If it is a debugging interface, it is used for module configuration and firmware upgrades, supports on-site parameter tuning and maintenance, and integrates ESD protection circuitry to adapt to industrial electromagnetic environments. The bus interface 26 is a circular connector of the same series as the power interface 25, but with different pin counts or interface key positions. It has a metal shielding layer and a double sealing design. The bus interface 26 supports industrial bus protocols (such as Profinet / Modbus-RTU) to achieve cascaded communication with distributed IO networks. In the event of a failure in communication interface 22, the system automatically switches to this interface to ensure data transmission continuity. It also supports daisy-chain topology to reduce wiring complexity. All interfaces of protocol module unit 2 meet the IP67 protection standard and achieve leak-free operation at a depth of 1 meter for 30 minutes through a sealing ring and metal locking structure, making it suitable for industrial environments with humidity, dust, and short-term liquid splashes.

The positioning member 35 passes through the mounting hole in the clearance groove 34 and is installed to the base plate 1. Two mounting feet 33 are also provided on both sides of the bottom of the IO signal body 31. In this embodiment, the IO signal interface 32 is used to connect to external sensors / actuators to realize the acquisition and control output of digital / analog signals, and is the core signal interaction port of the module.

[0041] In a preferred embodiment of this utility model, the IO signal unit 3 includes an IO signal body 31.

A clearance groove 34 is respectively opened at both ends of the surface of the IO signal body 31, and a positioning member 35 passes through the mounting holes in the clearance groove 34 and is installed to the base plate 1. In this embodiment, the IO signal unit 3 can achieve modular assembly. The staggered interface layout and positioning structure help reduce wiring complexity and adapt to the installation requirements of industrial environments.

[0042] IP67 protection requires complete dust protection (no dust intrusion) and no harmful effects after immersion in 1 meter of water for 30 minutes. This is achieved through the coordinated efforts of four key aspects: sealed construction, material matching, interface protection, and testing and verification.

[0043] Sealed design

[0044] Static sealing: O-rings, ultrasonic / laser welding of plastic shell seams, or sealant filling of metal shells are used to eliminate gaps at fixed interfaces;

[0045] Dynamic sealing: Moving parts use silicone sealing caps, labyrinth structures, or double O-rings to balance operational needs and protection;

[0046] Structural optimization: The fillet radius of the housing interface is increased to more than 0.5mm, which evenly distributes the sealing stress and reduces the risk of leakage.

[0047] Material selection and adaptation

[0048] Sealing materials: Silicone rubber is suitable for industrial modules; fluororubber (weather-resistant and chemical-resistant) is used for outdoor equipment; nitrile rubber (oil-resistant) is suitable for lubrication environments;

[0049] Internal protection: The PCB board is coated with conformal coating (polyurethane / acrylic), and sensitive areas are potted with silicone to enhance moisture resistance and corrosion resistance.

[0050] Interface and opening protection

[0051] Connectors / Cables: IP67 waterproof connectors (M12 / M8 round connectors) with metal shielding and double sealing design;

[0052] Breathability requirement: Use a waterproof and breathable membrane to balance the air pressure in the cavity while blocking moisture;

[0053] Installation and sealing: The module is fixed to the base plate by positioning groove and sealing gasket to ensure no gap after assembly.

[0054] Environmental adaptability: Combining temperature and humidity cycling and vibration and shock tests, the stability of protective performance under extreme working conditions is verified.

[0055] The technical advantages of the IP67 protection rating unit-type remote I / O module based on a high-speed backplane are:

[0056] Customers can flexibly select protocol module units according to the bus protocol used in their field. The modules can then be used under any fieldbus protocol. Different application environments allow for the selection of different numbers and signal types of I / O signal units based on usage requirements. This allows the modules to be used in environments requiring any type of I / O. The protocol module units and I / O signal units utilize high-speed signal transmission to better meet the real-time requirements of the field. The modules meet an IP67 protection rating, allowing them to be installed anywhere, unlike previous IP20 modules which required rack mounting.

[0057] It should be noted that this utility model only improves the hardware structure of the industrial I / O module, and does not improve the control program. The control program and the internal control module of the industrial I / O module are all existing technologies.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
