[0023] Example 1: Please see Figure 1 - Figure 7 This embodiment provides a protective housing and an industrial communication terminal, including a housing body 1. The housing body has an inner cavity for accommodating the industrial communication terminal. The housing body 1 further includes: The multi-functional interface compartment 2 is integrated on the top of the outer shell 1. The multi-functional interface compartment 2 has an upward-opening compartment. The top of the multi-functional interface compartment 2 is sealed by a flip-up waterproof cover 201. The inside of the waterproof cover 201 is integrated with a dust plug hanger 202.

[0024] A multi-functional interface compartment 2 is centrally located at the top for convenient line access and management. A flip-up waterproof cover 201 provides space for interface operation when open and ensures a dustproof and waterproof seal when closed. An integrated dust plug holder 202 inside the cover allows for easy storage of dust plugs when the interface is not in use, preventing loss and keeping the interface clean.

[0025] The dynamic air duct assembly 3 is disposed on the side wall of the outer shell body 1. The dynamic air duct assembly 3 includes an outer insect-proof net 301, a rotatable air guide louver 302 and an inner dust filter cotton 303, which are stacked sequentially from the outside to the inside. Through the coordinated operation of the multi-layered structure from the outside in, the equipment can effectively protect against multiple pollutants such as dust, insects, and water droplets while ensuring ventilation and heat dissipation inside the main body 1, thus improving the long-term operational reliability of the equipment in harsh industrial environments.

[0026] The elastic buffer and heat-conducting base 4 is located at the bottom of the inner cavity of the outer shell body 1. The upper surface of the elastic buffer and heat-conducting base 4 is provided with a limiting groove 401 for fitting and snapping the bottom of the industrial communication terminal. The interior of the elastic buffer and heat-conducting base 4 is embedded with a heat-conducting silicone pad 402. The bottom of the elastic buffer and heat-conducting base 4 is provided with multiple downward protruding heat dissipation columns 403.

[0027] The limiting groove 401 on the upper surface can securely fix the communication terminal module and prevent it from moving or loosening in the inner cavity. The internal thermally conductive silicone pad 402 and the raised heat dissipation column 403 at the bottom can efficiently conduct the heat generated by the communication terminal during operation to the outer shell body 1, and use the outer shell body 1 for heat dissipation, which solves the heat dissipation buffering problem of key modules in the confined space, and has the dual functions of shock absorption and heat conduction.

[0028] See Figure 1 , Figure 2 , Figure 3 Specifically, the waterproof cover 201 is connected to the multi-functional interface compartment 2 via a torque shaft, and the dust plug holder 202 is provided with a slot that matches the shape of common interface dust plugs.

[0029] The waterproof cap 201 is connected to the torsion shaft, allowing it to remain suspended at any angle for easy operation. The slots on the dust plug holder 202 ensure a secure engagement of the dust plug, further preventing it from falling off in vibrating environments.

[0030] See Figure 1 , Figure 2 , Figure 4 Specifically, the airflow guide louver 302 rotates within the range of 0 to 90°, and the surface of the blades of the airflow guide louver 302 is coated with a hydrophobic coating.

[0031] The airflow deflector louver 302 is adjustable within the range of 0 to 90°, allowing for flexible adjustment of the air intake angle and airflow according to ambient wind speed, wind direction, or heat dissipation requirements, thereby optimizing heat dissipation efficiency. The hydrophobic coating on the blade surface of the airflow deflector louver 302 effectively prevents water droplets from adhering and penetrating, enhancing its protective capabilities in humid or rainy environments.

[0032] See Figure 1 , Figure 2 Specifically, a temperature and humidity sensor 101 is also installed in the inner cavity of the outer shell 1, and the temperature and humidity sensor 101 is electrically connected to a corresponding control module.

[0033] Based on the monitored temperature and humidity data, the control module can ultimately adjust the rotation angle of the airflow guide louver 302.

[0034] See Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 Specifically, the elastic buffer and heat-conducting base 4 is made of highly elastic rubber material, the protruding heat dissipation column 403 contacts the bottom plate of the outer shell body 1, and the corresponding position on the bottom plate is provided with outward protruding heat dissipation fins 102.

[0035] The elastic cushioning and thermally conductive base 4, made of highly elastic rubber material, provides excellent shock absorption and cushioning performance, protecting internal terminals from impact and vibration damage. The raised heat dissipation pillars 403 contact the bottom plate of the casing and direct heat to the heat dissipation fins 102 on the outside of the bottom plate, greatly increasing the heat dissipation area and improving passive heat dissipation efficiency, making it suitable for fanless, hermetically sealed designs.

[0036] Working principle: Physical Protection and Interface Management: The main body 1 is physically protected by a multi-functional interface compartment 2 integrated at the top. The multi-functional interface compartment 2 features an upward-opening design and is sealed by a flip-up waterproof cover 201. When cables need to be plugged in or unplugged, the waterproof cover 201 is opened for operation; after operation, the waterproof cover 201 is closed, using its seal to prevent the intrusion of dust and water droplets. The dust plug holder 202 integrated inside the waterproof cover 201 provides a dedicated storage location, ensuring that unused interfaces are properly protected by dust plugs, preventing foreign objects from entering and causing poor contact or short circuits. This design solves the problems of easily lost small parts and easily contaminated interfaces in industrial environments.

[0037] Intelligent ventilation and dust protection: The dynamic air duct assembly 3 installed on the side wall achieves a balance between heat dissipation and protection. This is based on multi-layer filtration and a controllable air duct. The outermost insect screen 301 first blocks larger foreign objects such as mosquitoes and willow catkins. The middle rotatable airflow guide louvers 302 are active adjustment components; their blades can rotate within a range of 0–90°, adjusting the airflow volume and direction by changing the angle to optimize heat dissipation efficiency. The hydrophobic coating on the surface of the airflow guide louvers 302 allows water droplets to roll off quickly, preventing water seepage. The innermost dust filter cotton 303 filters fine dust, ensuring clean air entering the equipment. Furthermore, the temperature and humidity sensor 101 installed inside the main body 1 monitors the internal environment in real time. Its data can be linked to the control module to assist in adjusting the opening angle of the airflow guide louvers 302, achieving intelligent temperature control based on environmental conditions.

[0038] Shock Absorption and Efficient Heat Conduction: The elastic cushioning and heat-conducting base 4, located at the bottom of the inner cavity of the main body 1, undertakes the responsibilities of mechanical protection and thermal management. Its highly elastic rubber material body can effectively absorb and buffer vibrations and impacts from the outside, protecting the delicate communication terminal module inside. During operation, the heat generated by the communication terminal is first transferred to the thermally conductive silicone pad 402 inside the base through the contact surface at its bottom. The thermally conductive silicone pad 402 has good thermal conductivity. The heat is then guided to multiple downward-facing raised heat dissipation columns 403 at the bottom of the base. These raised heat dissipation columns 403 are in close contact with the bottom plate of the main body 1, and finally conduct the heat to the heat dissipation fins 102 on the outside of the bottom plate of the main body 1. By efficiently conducting the heat inside the device to the entire surface area of ​​the main body 1 for passive heat dissipation, the heat dissipation problem of key modules inside the sealed protective shell is successfully solved, achieving a unity of protection and heat dissipation.

[0039] In this embodiment, the industrial communication terminal includes: A multi-protocol communication core module, used to simultaneously run at least two industrial fieldbus protocol stacks and at least one industrial Ethernet protocol stack; The edge computing and data preprocessing module is used to perform local parsing, filtering, compression, and edge-side logical operations on the data from the connected field devices. The wireless roaming and link aggregation module integrates at least two independent wireless communication units, supports seamless roaming between multiple wireless networks, and can aggregate multiple wireless links into a single logical channel to improve bandwidth and reliability.

[0040] The unified configuration and management interface module provides a unified web configuration interface, OPC UA server interface, and RESTful API, allowing remote configuration and management of communication protocols, data processing logic, and wireless parameters.

[0041] By integrating a protective shell with multiple protective functions with a high-performance industrial communication system, an integrated industrial communication terminal is formed. This terminal not only has strong physical protection, but its internal functional system also achieves multi-protocol compatibility, intelligent edge processing, high reliability of wireless communication, and unified and convenient management. It meets the comprehensive needs of modern industrial IoT for data acquisition, processing, transmission, and equipment management, and reduces the complexity of system integration.

[0042] Specifically, the edge computing and data preprocessing module has a built-in rule engine and a lightweight time-series database, which executes data preprocessing scripts based on time or event triggers and temporarily stores historical data.

[0043] The edge computing module has a built-in rule engine and a lightweight time-series database, enabling the terminal to perform complex logical processing and temporary storage at the data source. On the one hand, this reduces the uploading of invalid data and saves network bandwidth and cloud storage costs; on the other hand, it can maintain local logical operation and data temporary storage when the network is unstable or interrupted, thereby improving system autonomy and continuity.

[0044] Specifically, the wireless roaming and link aggregation module supports wireless communication methods including 5G / 4G, Wi-Fi 6, and LoRa, and intelligently selects or aggregates communication paths based on signal strength, network congestion, and service priority.

[0045] By integrating multiple wireless communication methods and supporting intelligent routing and aggregation, the system ensures that terminals can obtain optimal and highly reliable wireless connections in various industrial scenarios. Link aggregation technology further enhances data transmission bandwidth and reliability, meeting the demands of demanding business transmission requirements.

[0046] Specifically, industrial communication terminals also include breakpoint resume and data buffer; When a network interruption is detected, the data to be uploaded is automatically stored in the local cache and will be automatically resumed after the network is restored.

[0047] The design of breakpoint resume and data buffer ensures that critical on-site data is not lost during temporary network interruptions. The terminal can automatically cache data and resume transmission after the network is restored, greatly enhancing the reliability and integrity of data reporting in complex network environments.

[0048] Working principle: Multi-protocol access and data aggregation: The terminal's multi-protocol communication core module is the data entry point, capable of simultaneously running multiple industrial fieldbus (such as PROFIBUS, Modbus) and industrial Ethernet (such as PROFINET, EtherNet / IP) protocol stacks. By monitoring and processing data from different protocol networks in parallel, it unifies signals from heterogeneous PLCs, sensors, actuators, and other field devices into a standardized data format that can be processed internally, solving the "information silo" problem caused by the coexistence of multiple protocol devices in industrial fields.

[0049] Edge-side intelligent preprocessing: The edge computing and data preprocessing module is the "brain" of the terminal. It has a built-in rule engine and a lightweight time-series database. After receiving raw data from the communication core module, it first performs data cleaning, filters outliers, compresses redundant information, and executes simple logical operations (such as average calculation and limit alarms) according to pre-defined rule scripts (e.g., based on time or event triggers). The processed valid data is temporarily stored in the local time-series database. This process significantly reduces the amount and frequency of data that needs to be uploaded to the cloud or host computer, lowers network bandwidth pressure and cloud computing load, and achieves rapid local response.

[0050] High-reliability wireless transmission: The wireless roaming and link aggregation module is responsible for remote data upload. It integrates multiple independent wireless communication units (such as 5G / 4G, Wi-Fi 6, LoRa). It continuously monitors the signal strength and network congestion status of each wireless link, and dynamically selects the optimal communication path based on the service priority of data transmission. When the bandwidth of a single link is insufficient, it can aggregate multiple wireless links into a high-bandwidth, high-reliability logical channel for data transmission. When equipment moves or the current network quality deteriorates, it can achieve seamless roaming between different networks (such as switching from Wi-Fi in the factory to a 5G network), ensuring uninterrupted data connection.

[0051] Data Assurance and Remote Management: Resumable transmission and data caching ensure reliable data transfer. The module monitors network connectivity in real time. Upon detecting a network interruption, it immediately and automatically transfers the data packets that should have been uploaded to a local non-volatile buffer. Once the network is restored, the system automatically re-initiates transmission from the point of interruption, ensuring no data loss. The entire terminal configuration and management are handled through a unified configuration and management interface module, which provides a web interface, OPCUA server, and RESTful API. Administrators, regardless of location, can remotely configure communication protocol parameters, edit edge processing rules, and set wireless network preferences via a browser or host computer software, achieving centralized and standardized operation and maintenance of distributed edge devices.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
