Description

Technical Field

[0001] This invention belongs to the field of communication gateway technology, specifically a data acquisition communication gateway. Background Technology

[0002] With the rapid development of industrial automation and IoT technologies, data acquisition and communication gateways have been widely used in various industrial sites, intelligent monitoring systems, and remote control systems. As a core component connecting field devices and host computer systems, the data acquisition and communication gateway undertakes key functions such as data acquisition, protocol conversion, and signal transmission. Its operational stability directly affects the reliability of the entire system.

[0003] However, industrial environments are complex and variable, with equipment often facing harsh conditions such as vibration, impact, and high temperatures. Traditional data acquisition and communication gateways mostly employ rigid installation structures, lacking effective shock absorption and buffering designs. When the equipment is subjected to external mechanical impacts or continuous vibration, internal electronic components are prone to loosening, solder joints to crack, or even circuit board damage, severely affecting the normal operation and lifespan of the equipment. Furthermore, existing gateway equipment also has shortcomings in installation and maintenance. The gateway body is typically installed using screws, requiring specialized tools for disassembly, making the process cumbersome and hindering rapid on-site maintenance and equipment replacement. Moreover, during prolonged operation, the internal electronic components of the gateway generate a significant amount of heat. If the heat dissipation design is inadequate, heat accumulation can lead to increased equipment temperature, resulting in performance degradation, system instability, and even component aging and damage. Although some equipment is equipped with ventilation holes or fans, inadequate airflow design leads to low air circulation efficiency, making effective thermal management difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a data acquisition and communication gateway to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a data acquisition and communication gateway, comprising a protective shell, a grooved rod, and a gateway body, wherein the grooved rod is provided with a sliding groove, and the gateway body is placed inside the protective shell, and a shock-absorbing mechanism for preventing the gateway body from impact is installed in the sliding groove;

[0006] The shock absorption mechanism includes a damping rod, and there are two sets of damping rods. The two sets of damping rods are respectively fixed to both ends of the slide groove. A slider is fixed to the end of the damping rod away from the slide groove, and a return spring is fixed to the slider. The end of the return spring away from the slider is fixed to the slide groove and is sleeved on the damping rod. A driving link is hinged to the slider, and the end of the driving link away from the slider is hinged to the bottom of the protective shell.

[0007] As a further preferred embodiment of this technical solution: the groove rod is provided in two sets, and a connecting rod is fixedly connected between the two sets of groove rods. A telescopic rod for limiting the movement of the protective shell is fixedly connected to the connecting rod, and the end of the telescopic rod away from the connecting rod is fixedly connected to the protective shell.

The gateway body is provided with a socket, and the plug rod is slidably connected to the socket. At the same time, a pull rod is fixedly connected to the end of the plug rod away from the socket.

[0009] As a further preferred embodiment of this technical solution: a first spring for providing locking force is sleeved on the insertion rod, and the two ends of the first spring are respectively fixed to the protective shell and the pull rod;

[0010] As a further preferred embodiment of this technical solution: the protective shell is provided with a guide groove, and the guide groove limits and guides the movement of the gateway body through a sliding plate connected internally, while the end of the sliding plate away from the guide groove is fixed to the gateway body.

[0011] As a further preferred embodiment of this technical solution: a fan for heat dissipation of the gateway body is installed at the bottom of the protective shell, and a ventilation plate for ventilation is fixed on the protective shell. At the same time, an air outlet is provided at the top of the protective shell for air outlet, and heat dissipation holes for air circulation are provided on the upper and lower sides of the gateway body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this invention, by setting a shock-absorbing mechanism in the chute, including a damping rod, a slider, a return spring and a drive linkage, when the gateway body is subjected to external impact or vibration, the shock-absorbing mechanism can effectively absorb and buffer the impact energy. The return spring and the damping rod work together to achieve bidirectional buffering and automatic reset, which significantly improves the operating stability and service life of the equipment under complex working conditions.

[0014] 2. In this invention, the plug rod in the snap-fit ​​mechanism can be slidably inserted into the socket of the gateway body. With the help of the first spring, a continuous locking force is provided to ensure that the gateway body is stably installed in the protective shell, preventing loosening or falling off due to vibration or movement. This improves the safety and reliability of the equipment operation. At the same time, the user only needs to pull the lever to disengage the plug rod from the socket, quickly completing the disassembly and replacement of the gateway body in the protective shell without tools, which greatly improves the maintenance efficiency and on-site operability of the equipment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example

[0025] Please see Figures 1-6 As shown, the present invention provides a technical solution: a data acquisition and communication gateway, including a protective shell 1, a groove rod 2, and a gateway body 5. The groove rod 2 is provided with a sliding groove 3, and the gateway body 5 is placed inside the protective shell 1. A shock-absorbing mechanism 4 for preventing the gateway body 5 from impact is installed in the sliding groove 3.

[0026] The shock absorption mechanism 4 includes a damping rod 41, and there are two sets of damping rods 41. The two sets of damping rods 41 are respectively fixed to both ends of the slide groove 3. A slider 42 is fixed to the end of the damping rod 41 away from the slide groove 3. A return spring 43 is fixed to the slider 42. The end of the return spring 43 away from the slider 42 is fixed to the slide groove 3 and is sleeved on the damping rod 41. A drive connecting rod 44 is hinged to the slider 42, and the end of the drive connecting rod 44 away from the slider 42 is hinged to the bottom of the protective shell 1.

[0027] Furthermore, the gateway itself has built-in program functions, including: multi-protocol data acquisition capability, virtual channel function, and remote operation and maintenance function;

[0028] It has multi-protocol data acquisition capabilities, supporting the acquisition of Modbus RTU / TCP protocol device data, and supports communication with mainstream PLC brands, including Siemens PLCs and Mitsubishi PLCs, thereby enabling unified access of heterogeneous devices and making it suitable for various industrial automation scenarios.

[0029] Virtual channel functionality includes: 485 virtual channel and TCP virtual channel;

[0030] The 485 virtual channel can map a local RS-485 interface to cloud or remote central software;

[0031] TCP virtual channels can penetrate the communication ports of local TCP devices (such as PLCs and HMIs) to remote servers, enabling remote debugging, monitoring, and data acquisition. This eliminates the need for public IP addresses or complex routing configurations, making it suitable for remote centralized management of distributed sites and unattended computer rooms.

[0032] The remote operation and maintenance function supports remotely upgrading gateway firmware or configuration files via the network without on-site operation, enabling unified upgrades of batch devices, reducing maintenance costs. It also supports remotely restarting devices through the central platform when a gateway malfunctions, quickly restoring services and significantly improving device manageability and response speed, making it suitable for large-scale deployment scenarios.

[0033] In this embodiment, specifically: the groove rod 2 is provided in two sets, and a connecting rod 45 is fixedly connected between the two sets of groove rod 2. A telescopic rod 46 for limiting the movement of the protective shell 1 is fixedly connected to the connecting rod 45, and the end of the telescopic rod 46 away from the connecting rod 45 is fixedly connected to the protective shell 1.

[0034] Further: Two sets of groove rods 2 and two sets of shock absorption mechanisms 4 are respectively installed at the front and rear ends of the bottom of the protective shell 1, and the angle between the two sets of drive connecting rods 44 inside one set of shock absorption mechanism 4 is an obtuse angle;

[0035] In this embodiment, specifically: a locking mechanism 6 for locking the gateway body 5 is installed on the protective shell 1, and the locking mechanism 6 includes a plug rod 61. The plug rod 61 is slidably connected to the protective shell 1. The gateway body 5 is provided with a socket 62, and the plug rod 61 is slidably connected to the socket 62. At the same time, a pull rod 63 is fixedly connected to the end of the plug rod 61 away from the socket 62.

[0036] Furthermore: There are two sets of insertion rods 61 and insertion holes 62, and the two sets of insertion rods 61 are located at both ends of the pull rod 63, while the locking mechanism 6 is located on the right side of the protective shell 1;

[0037] In this embodiment, specifically: a first spring 64 for providing locking force is sleeved on the insertion rod 61, and the two ends of the first spring 64 are respectively fixed to the protective shell 1 and the pull rod 63;

[0038] Further: There are two sets of first springs 64, and the two sets of first springs 64 are located at both ends of the pull rod 63;

[0039] In this embodiment, specifically: the protective shell 1 is provided with a guide groove 65, and the guide groove 65 limits and guides the movement of the gateway body 5 through the internally slidably connected sliding plate 66, while the end of the sliding plate 66 away from the guide groove 65 is fixed to the gateway body 5.

[0040] Further: The guide groove 65 is provided on the left side of the protective shell 1, while the slide plate 66 is provided on the side of the gateway body 5 away from the socket 62;

[0041] In this embodiment, specifically: a fan 7 for cooling the gateway body 5 is installed at the bottom of the protective shell 1, and a ventilation plate 8 for ventilation is fixed on the protective shell 1. At the same time, an air outlet 9 for air outlet is provided at the top of the protective shell 1, and heat dissipation holes 10 for air circulation are provided on the upper and lower sides of the gateway body 5.

[0042] Further: the ventilation plate 8 is located above the fan 7, the heat dissipation hole 10 is located above the ventilation plate 8, and the air outlet 9 is located above the heat dissipation hole 10.

[0043] Working principle or structural principle: When the gateway body 5 needs to be installed, the gateway body 5 is first inserted into the protective shell 1 through the opening. During the lowering process, the sliding plate 66 on one side of the gateway body 5 slides along the guide groove 65 set inside the protective shell 1 to achieve precise guidance, prevent deviation or collision, and ensure accurate installation position. At the same time, when the gateway body 5 is fully inserted, the insertion hole 62 on its side wall is exactly aligned with the insertion rod 61 on the protective shell 1. Since the insertion rod 61 is fitted with a first spring 64, and the two ends of the first spring 64 are respectively connected between the protective shell 1 and the pull rod 63, the elastic force of the first spring 64 pushes the insertion rod 61 to automatically insert into the insertion hole 62, completing the locking and positioning. At this time, the gateway body 5 is firmly fixed inside the protective shell 1 to prevent loosening due to vibration or movement during operation. Furthermore, the gateway body 5 pushes the slider 42, which in turn drives the damping rod. 41 retracts within the slide groove 3, while the return spring 43 is compressed. The movement of the slider 42 drives the drive linkage 44 to rotate. Thus, when the gateway body 5 is subjected to external impact or vibration, the shock absorption mechanism 4 can effectively absorb and buffer the impact energy. At the same time, the fan 7 installed at the bottom of the protective shell 1 starts, forcibly drawing in external air, which enters the interior of the protective shell 1 through the ventilation plate 8. The airflow passes through the heat dissipation holes 10 on the upper and lower sides of the gateway body 5, forming a three-dimensional air channel with horizontal and vertical directions on its surface. Finally, the hot air is discharged from the top air outlet 9, achieving efficient forced convection heat dissipation, effectively reducing the internal temperature, and ensuring the stable operation of electronic components. Finally, if it is necessary to disassemble the gateway body 5, simply pull the pull rod 63 outward, causing the insertion rod 61 to overcome the elastic force of the first spring 64 and exit from the insertion hole 62, thereby unlocking it. Then, the gateway body 5 can be smoothly removed upward for easy maintenance or replacement.
