Description

Technical Field

[0001] The present invention relates to the technical field of industrial field data acquisition devices, and in particular to a field data acquisition gateway. Background Art

[0002] Smart manufacturing technologies (such as big data analysis and prediction) are needed across all aspects of modern manufacturing, including product development, process optimization, quality control, and logistics planning, to improve output efficiency and product competitiveness. Data acquisition and data acquisition gateways are essential components of smart manufacturing. Data acquisition is essential for achieving Industrial Internet 4.0 and smart manufacturing, serving as a bridge between manufacturing field equipment and data-consuming terminals. Currently, data acquisition relies heavily on data acquisition gateways, which are data communication devices that parse, convert, and collect discrete data from industrial sites. The converted data can meet the data needs of common terminals, making data acquisition gateways indispensable in the field of smart manufacturing. The rapid development of industrial Internet technologies in recent years has made the role of data acquisition gateways increasingly prominent.

[0003] After researching several major automotive parts suppliers, we concluded that, based on data collection methods, critical production and operation data from equipment terminals falls into six main categories: open-source PLCs, dedicated equipment, closed-source industrial computers, imaging, sensors, and manual recording. The first five categories, representing approximately 97% of data, are automatically collected and are the primary targets for data collection gateways. However, the diverse hardware interfaces, transmission protocols, and data storage formats of these five target categories significantly increase the difficulty and cost of data collection.

[0004] Currently, there are relatively few data collection gateways available for commercial application, and the existing ones can be divided into the following three categories: data collection gateways that are customized for each data collection object, but have high development costs and low deployment efficiency; data collection gateways that come with the device or are brand-matched, which are often expensive and not universal and have serious limitations; data collection gateways developed by third parties based on the data communication protocols they master, which are only applicable to specific types of equipment and also have disadvantages such as high cost and strong limitations.

[0005] The three data acquisition gateways mentioned above share a common drawback: high environmental requirements and a high failure rate. They cannot withstand long-term use in complex industrial environments such as those characterized by high temperatures, high humidity, high salt content, and high acidity. In summary, existing data acquisition gateways suffer from the following significant disadvantages: high cost; low deployment efficiency; significant limitations requiring customized development; poor environmental adaptability and high failure rates. These disadvantages have resulted in data acquisition currently occupying a significant portion of the overall digital factory development budget. Summary of the Invention

[0026] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an embodiment of the present disclosure proposes a data acquisition gateway for field use, comprising: a shell 11, a main control board 25, a power module, an interface array 23, a cooling assembly 12, a sealing assembly 13, a buffer assembly 14, and an electromagnetic shielding layer 15; the shell 11 has an accommodating cavity inside, and functional openings are opened on the shell 11, and the functional openings include an interface array 23 opening, a power opening, a heat dissipation opening and a buffer opening, the interface array 23 opening is opened on the front side panel of the shell 11, the power opening is opened on the rear side panel of the shell 11, the heat dissipation opening is opened on the left side panel of the shell 11, and the buffer opening is opened on the bottom plate of the shell 11; the main control board 25 is arranged in the accommodating cavity; the power module is arranged in the accommodating cavity, and the power module is electrically connected to the main control board 25; the interface array 23 is embedded in the interface array 23 opening, and the interface array 23 is electrically connected to the main control board 25; the cooling assembly 12 It includes a fan 121, a heat dissipation fin 122, a flat plate heat pipe 123, and a circulating water path 124. The flat plate heat pipe 123 includes a first plate portion and a second plate portion perpendicular to each other. The first plate portion is arranged parallel to the main control board 25, and the first plate portion is in contact with the main control board 25 and the power module. The second plate portion is embedded in the heat dissipation opening and fits the heat dissipation opening. The second plate portion is parallel to the left side plate of the shell 11. The circulating water path 124 is arranged in the heat dissipation fin 122, one side of the heat dissipation fin 122 is in contact with the second plate portion, and the other side of the heat dissipation fin 122 is fixedly connected to the fan 121; the buffer assembly 14 includes a plurality of oil pressure buffers, and the plurality of oil pressure buffers extend into the accommodating cavity from the bottom plate of the shell 11 respectively, and the top ends of the plurality of oil pressure buffers are respectively fixedly connected to the main control board 25; the sealing assembly 13 includes a plurality of seals, and the plurality of seals are respectively arranged at the functional openings; the electromagnetic shielding layer 15 is a closed cavity structure, and the electromagnetic shielding layer 15 is evenly distributed along the inner wall of the shell 11.

[0027] Specifically, if Figure 1-Figure 5 As shown, the shell 11 adopts a cubic structure, and the front side panel, left side panel, rear side panel and right side panel of the shell 11 are fixedly connected in sequence, and the top panel and bottom panel are fixedly connected to the top and bottom of each side panel respectively, so that a closed accommodating cavity is formed inside the shell 11, and the fixed connection between the external device and the shell 11 is achieved by opening a functional opening on the shell 11. The external device includes an interface array 23, a cooling component 12, a buffer component 14, a display 24, a switch module 22, etc. In some embodiments, the shell 11 includes a structural layer and an anti-corrosion layer.

[0028] The main control board 25 is the core of the gateway's operations. Similar to a microcomputer, it houses multiple microprocessors that support the gateway's data acquisition functions. These microprocessors include a central CPU, a network card driver controller, a Bluetooth driver controller, a level signal microprocessor, a network driver controller (e.g., 4G network, 5G network, etc.), a power control circuit, a camera driver controller, memory, and other supporting circuits. The gateway's operating system runs on the main control board 25, and data acquisition, processing, and transmission programs are executed within the operating system's built-in programs. In practical applications, the main control board 25 can be a commercially available microcomputer, such as the Raspberry Pi 4B control board.

[0029] The main control board 25 includes a communication module, and the main control board 25 is connected to a host computer via the communication module. The host computer can be a PC, a cloud, or a mobile terminal.

[0030] The main control board 25 includes a data acquisition system, which includes a data acquisition module. The data acquisition module includes multiple preset acquisition parameters, each corresponding to a plurality of target acquisition devices. These preset acquisition parameters include CPU hardware information such as the target acquisition device's IP address, port number, stack number, and slot number; program information such as the data type and data address; and data acquisition elements such as the acquisition frequency. The preset acquisition parameters are used to enable the data acquisition module to collect specified data from the target acquisition devices. The multiple preset acquisition parameters are pre-stored in the data acquisition module of the main control board 25. The multiple target acquisition devices include open source PLC devices, dedicated devices, closed source industrial computers or control motherboards, sensor devices, and image recognition devices. The data acquisition module includes multiple data acquisition units, each of which collects data from the target acquisition devices based on the corresponding preset acquisition parameters.

[0031] In another embodiment, the main control board 25 receives preset acquisition parameters online by connecting to a host computer. The main control board 25 then sets the preset acquisition parameters for the data acquisition module online via computer-side software (i.e., the host computer) and downloads them to the data acquisition module on the main control board 25. The data acquisition module then runs according to the set program to achieve data acquisition. For example, when setting the preset acquisition parameters for a target acquisition device, the preset acquisition parameters for the target acquisition device can be set in the computer-side software and downloaded to the network main control board 25 for execution. For example, to acquire data from a Siemens S7 1200 PLC, CPU hardware information such as the PLC's IP address, port number, stack number, and slot number, PLC program information such as data type and data address, and data acquisition elements such as the acquisition frequency can be downloaded to the main control board 25, allowing the main control board 25 to collect the specified data information.

[0032] The data acquisition system also includes a self-test module, which is used to initialize and check whether the gateway hardware is normal and send an alarm signal if an abnormality occurs. During the functional self-test of the gateway body, the computer software can view and analyze the gateway body self-test structure, obtain self-test messages, and analyze the cause of the gateway body failure.

[0033] The data acquisition system also includes gateway parameters, which include data acquisition module startup parameters, data acquisition module stop parameters, data sending and receiving addresses, data sending and receiving frequencies, data sending and receiving fields, etc.

[0034] The data acquisition system includes a system update module, which receives system update parameters via a connection to a host computer. These system update parameters are used to update the data acquisition parameters of the target acquisition devices. This system update module enables secondary development of the data acquisition functions of the main control board 25. The interaction between the computer-side software and the system update module allows the addition of data acquisition parameters for devices not covered by the original data acquisition module program. The system update module supports secondary development. If the built-in program does not cover the device being acquired, developers can manually add acquisition programs to expand functionality.

[0035] The main control board 25 supports secondary development for new data acquisition scenarios by loading an embedded data acquisition system. The computer software has built-in communication protocols and communication parameter setting interfaces for various industrial equipment, which can realize one-to-many acquisition. At the same time, data acquisition equipment can be customized according to user needs. At the same time, the computer software also supports the setting of the data sending function of the gateway body, as well as the management of the self-diagnosis and alarm signals of the gateway body hardware equipment.

[0036] The power module includes a plug-in power supply 211, which is used to provide power to the main control board 25. Other electrical components of the data acquisition gateway are electrically connected to the power module through connections to the main control board 25. A power opening is provided for receiving a power connector, which is embedded in the power opening. The power module is connected to an external power supply system through the power connector. In some embodiments, the power module is fixedly mounted on the main control board 25.

[0037] Interface array 23 is a key interface for data acquisition, interacting with the target acquisition device. Due to the large number of industrial field devices and the diverse interface formats, interface array 23 integrates different data interfaces, such as RJ45 network ports, USB, mini USB, Type-C, RS232 / RS485 / RS422, and level signals. Data interfaces can operate simultaneously, enabling a single gateway to collect data from multiple devices. Furthermore, multi-interface array 23 supports expansion interfaces, such as external cameras, to expand data acquisition capabilities. By embedding interface array 23 within the openings of the interface column, a relatively fixed connection between housing 11 and interface array 23 is achieved. Interface array 23 connects to main control board 25 via internal wiring, which is located within the housing cavity and serves to connect interface array 23 and main control board 25.

[0038] The cooling component 12 is used to dissipate the heat generated by the main control board 25 and the power module to the outside to ensure the normal operation of the main control board 25 and the power module. Since the shell 11 is a sealed design, if the cooling component 12 is missing, the high heat generated by the main control board 25 and the power module during operation will easily damage the microcontroller on the main control board 25.

[0039] The first and second plate portions of the flat plate heat pipe 123 are integrally formed. The first plate portion of the flat plate heat pipe 123 is arranged parallel to and above the main control board 25 and the power module. Heat conduction between the cooling assembly 12 and the main control board 25 and the power module is achieved by abutting the main control board 25 and the power module. The second plate portion is embedded in the heat dissipation opening. Heat conduction is achieved by abutting the second plate portion and the heat dissipation fins 122. The fan 121 is arranged on the other side of the heat dissipation fins 122 to cool the heat dissipation fins 122. By arranging the fan 121 and the second plate portion on both sides of the heat dissipation fins 122, the temperature difference on both sides of the heat dissipation fins 122 is increased, thereby accelerating cooling. In some embodiments, the cooling assembly 12 also includes a heat conduction medium, which is a thermally conductive gel. The thermally conductive gel is used to connect the flat plate heat pipe 123 to the heating element on the main control board 25 and the heat dissipation fins 122.

[0040] The cooling assembly 12 specifically works by using the flat-plate heat pipe 123 to quickly conduct heat. In operation, the first plate of the flat-plate heat pipe 123 is in contact with the heat-generating elements (such as the microcontroller and the rechargeable lithium battery) on the main control board 25, and the second plate of the flat-plate heat pipe 123 is in contact with the heat dissipation fins 122. Since the heat dissipation fins 122 are connected with the heat dissipation fan 121, the circulating waterway 124, and other heat convection enhancement devices, the heat dissipation fins 122 can be maintained at a low temperature, thereby realizing the quick conduction of heat from the main control board 25 and the power module along the flat-plate heat pipe 123 to the heat dissipation fins 122, further dissipating to the outside of the shell 11, realizing the quick cooling of the inside of the shell 11, maintaining a stable temperature range, and delaying the service life of the equipment.

[0041] The heat dissipation power, appearance size, material, and other parameters of the flat-plate heat pipe 123 described above can be selected according to the heat-generating power of the heat-generating elements such as the main control board 25 and the power module.

[0042] The sealing assembly 13 isolates the inside of the shell 11 from the external environment (as shown in Figure 5 ), and plays a role in dustproof, waterproof, and pollution prevention. The sealing assembly 13 is composed of sealing structures distributed at various positions of the shell 11, including sealing structures existing at the opening positions of the shell 11 and the internal structure connection, such as the inner side of the heat dissipation fins 122, the fixed end of the oil buffer of the buffer assembly 14, the inner side of the display 24, and the disassembly positions of the side plates, top plate, and bottom plate of the shell 11. The sealing assembly 13 can select appropriate sealing materials according to actual needs, such as polytetrafluoroethylene and silicone rubber. Regardless of which sealing material is used, all similar sealing structures are within the scope of the present application.

[0043] The buffer assembly 14 is used to fix the main control board 25 in the accommodating cavity in the shell 11 (as shown in Figure 3 ). The buffer assembly 14 is composed of multiple oil buffers. When the gateway receives a severe impact, the buffer assembly 14 can effectively absorb the impact and prevent the main control board 25 from being damaged. The multiple oil buffers are fixed by screwing the bottom plate of the shell 11. The multiple oil buffers are adjustable devices. By adjusting the oil buffer, the distance between the main control board 25 and the bottom plate can be adjusted, thereby realizing the free contact (i.e., abutment) of the heat-generating elements on the main control board 25 and the flat-plate heat pipe 123. In this case, the oil buffer is in a slightly compressed state to ensure good heat transfer effect.

[0044] The electromagnetic shielding layer 15 is located on the inner side of the shell 11 and the outer side of the main control board 25. The electromagnetic shielding layer 15 is generally made of metal with electromagnetic shielding effect, such as iron, nickel-iron alloy, etc., and is uniformly distributed on the inner side of the shell 11, which can be in a mesh structure or a parallel structure, so as to form a complete electromagnetic isolation space inside the gateway body. Due to the electromagnetic shielding of the electromagnetic shielding layer 15, the modules on the main control board 25 that need to transmit signals wirelessly will be connected through an external antenna, and the external antenna is connected to the inside of the shell 11 through the external interface array 23.

[0045] In some embodiments, the display 24 is further included, and the display 24 is electrically connected with the main control board 25. The top plate of the shell 11 is provided with a display 24 opening, and the display 24 is embedded in the display 24 opening.

[0046] Specifically, Figure 1 and Figure 3 As shown in the figure, the display 24 is a touch screen. The display 24 combines the data acquisition state, the data acquisition result and the data acquisition unit running state through electrical connection with the main control board 25. In some embodiments, the display 24 receives self-diagnosis results, alarm information and the like. The sealing assembly 13 further includes a display 24 opening seal for sealing the connection between the display 24 and the shell 11.

[0047] In some embodiments, the switch module 22 is further included, and the switch module 22 is electrically connected with the main control board 25. The top plate of the shell 11 is provided with a switch opening, and the switch module 22 is embedded in the switch opening.

[0048] Specifically, Figure 1 and Figure 3 As shown in the figure, the switch module 22 is used to control the start or shutdown of each system and functional module on the main control board, or is used to switch each system and functional module on the main control board 25, etc. The switch module 22 further includes an indicator light, which is electrically connected with the main control board 25. The indicator light of the switch module 22 is used to indicate the working state of the gateway body. The switch module 22 uses a dark switch to prevent dust and water. The sealing assembly 13 further includes a switch opening seal for sealing the connection between the switch module 22 and the shell 11.

[0049] In some embodiments, the power module includes a direct insertion power supply 211 and a rechargeable battery 212. The direct insertion power supply 211 is electrically connected with the rechargeable battery 212, and the rechargeable battery 212 is electrically connected with the main control board 25.

[0050] Specifically, as Figure 1-Figure 3As shown, the power module includes a direct plug-in power supply 211 and a rechargeable lithium battery, wherein the direct plug-in power supply 211 can directly power the data acquisition gateway used in the field and can charge the rechargeable lithium battery; the rechargeable lithium battery is used when the data acquisition gateway used in the field is away from the power supply or still maintains the working state after a short power failure, and supports power-off continuation, data saving, parameter saving, alarm and other emergency operations of the data acquisition gateway used in the field after power failure.

[0051] In some embodiments, a solar component is further included, which is arranged outside the right side plate of the shell 11, and the solar panel 213 is electrically connected with the rechargeable battery 212.

[0052] Specifically, as shown in Figure 1-Figure 3 The solar component includes a solar panel 213, so that the data acquisition gateway used in the field can select solar power when used in the external environment, and the rechargeable lithium battery is charged through the solar panel 213, thereby reducing the energy consumption of the equipment.

[0053] In some embodiments, the water inlet and the water outlet of the circulating water path 124 are arranged at two ends of the heat dissipation fin 122.

[0054] Specifically, as shown in Figure 4 The circulating water path 124 is uniformly arranged in the heat dissipation fin 122 and uniformly abuts against the heat dissipation fin 122, one end of the circulating water path 124 enters the water inlet and the other end is the water outlet, the pipeline of the circulating water path 124 is made of heat-conducting material, and the circulating water path 124 functions to rapidly cool the heat dissipation fin 122, the main control board 25 and the power module when the gateway body is in a high-temperature and high-humidity industrial environment, so that the main control board 25 and the power module can normally work under the high-temperature and high-humidity conditions and meet the requirements of complex and changeable industrial environments; when the data acquisition gateway used in the field is in a normal-temperature working environment, the circulating water path 124 can be idle.

[0055] In some embodiments, the sealing assembly 13 further includes a plug for buckling the interface array 23.

[0056] Specifically, the sealing assembly 13 further includes a protective plug of the interface array 23, and when the external interface array 23 is not connected, the protective plug is used to seal each interface of the interface array 23, and when the data acquisition device is connected, the sealing treatment is performed after the connection is successful.
