Description

TECHNICAL FIELD

[0002] At present, industrial automation and Internet of Things application are developing vigorously, and industrial grade gateway equipment plays a core role in connecting various network systems. Its stability and reliability are like a cornerstone, supporting the smooth operation of the entire industrial network architecture. However, the existing industrial grade gateway equipment exposes many short boards that need to be solved in network switching. From the internal structure of the equipment, the network switching structure of some equipment is like a complex maze, with a large number of cumbersome line layout and complex signal conversion mechanism, which not only makes the production cost of the equipment high, but also greatly increases the probability of failure. Once a fault occurs, troubleshooting and repair work is like finding a needle in a haystack, the maintenance difficulty increases geometrically, and a large amount of manpower, material resources and time cost are consumed.

[0003] In terms of actual operation, the network switching process of some equipment is tedious and cumbersome, and the operator needs to go through multiple complex instruction input and parameter adjustment steps to try to realize the switching between different signal sources. This process not only takes a long time, but also in emergency situations, it is difficult to quickly and accurately complete the switching action. The rhythm of industrial production is compact, and any temporary network interruption or switching delay may cause the production line to stop, thereby causing serious impact on the continuity and efficiency of industrial production, leading to a series of chain reactions such as production delay and product quality decline.

[0004] In addition, industrial environments are often filled with various strong electromagnetic interference, electrical noise and complex physical environmental factors. The existing network switching structure is not capable of dealing with such harsh working conditions in terms of signal transmission stability and anti-interference ability. The signal frequently fluctuates, loses packets or even interrupts during transmission, which cannot meet the almost stringent demand of high reliability network connection in industrial environment, and poses a serious risk to the safe and stable operation of industrial production.

Obviously, the described embodiments of the utility model are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0034] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0035] Embodiment 1: the specific structure of the utility model is as follows:

[0036] Please refer to the attached Figures 1-7The present invention provides an industrial-grade gateway device with a network switching structure, comprising a housing and a first PCB board 7 disposed within the housing. The first PCB board 7 is equipped with a microcontroller, and the microcontroller is equipped with two sets of signal source terminal positions, each set of signal source terminal positions being equipped with an input terminal group and an output terminal group.

[0037] The front of the housing has an opening;

[0038] The industrial-grade gateway device has a network switching structure, which includes:

[0039] A pressable and rotatable switching knob 92 is provided at the opening. The switching knob 92 is an insulator, and its inward end is a cylindrical structure. The end face of the cylinder has a blind hole 924 and a groove is provided on the side ring surface of the cylinder. An arc-shaped second PCB board 923 is embedded in the groove. The second PCB board 923 has two sets of terminal groups, namely a first terminal group 922 and a second terminal group 925. The terminals on the first terminal group 922 and the second terminal group 925 are electrically connected one-to-one. The side ring surface of the cylinder is also provided with at least two protrusions 921 perpendicular to the circumferential direction of the ring surface.

[0040] A compression spring 93, a portion of which enters the blind hole;

[0041] An annular component 91, which is an insulator, is disposed within the housing. Its inner ring wall has two concave rings 911. On the side ring surfaces of both concave rings 911, there are elastic terminal groups 913. One set of elastic terminal groups 913 is connected one-to-one to one set of signal source terminals, and the other set of elastic terminal groups 913 is connected one-to-one to another set of signal source terminals. The upper elastic terminal group 913 serves as one signal transmission source, and the lower elastic terminal group 913 serves as another signal transmission source. The upper and lower elastic terminal groups 913 are staggered. Each set of elastic terminal groups 913 is divided into two sets of signal terminals. Both concave rings 911 are provided with straight grooves 912 leading to the upper end of the annular member 91. The protruding strip 921 can enter the concave ring 911 through the straight grooves 912 and can rotate within the concave ring 911 to form an anti-detachment structure. The two sets of terminal groups and the elastic terminal groups 913 are staggered. When the annular member 91 enters the concave ring 911 and rotates at an angle, the two sets of terminal groups and the two sets of signal terminals abut one-to-one and conduct the two sets of signal terminals.

[0042] The switching principle of this industrial-grade gateway device:

[0043] like Figures 3-7 As shown, the microcontroller of this invention is an STM32F4 series microcontroller, which has two signal source lines, such as... Figure 4As shown, the single-chip microcomputer is provided with a first signal source circuit 71 and a second signal source circuit 72, both of which are disconnected. The first signal source circuit 71 is connected to the lower elastic terminal group 913, and the second signal source circuit 72 is connected to the upper elastic terminal group 913.

[0044] The switching knob 92 enters from the concave ring 911 close to the upper elastic terminal group 913, at this time, the first terminal group 922 and the second terminal group 925 are misaligned with the upper elastic terminal group 913, and only need to rotate the switching knob 92 by an angle of 8-10 degrees. The contact head of the elastic terminal group 913 is pressed against the two groups of terminal groups one by one, and the circuit is turned on.

[0045] Since the convex strip 921 is rotated by an angle, the convex strip 921 is in the concave ring 911, and the convex strip 921 is limited to not be separated from the concave ring 911, thereby limiting the entire switching knob 92.

[0046] In order to prevent the switching knob 92 from rotating without external force, the first terminal group 922 and the second terminal group 925 are arranged as a concave surface, and the contact head of the elastic terminal group 913 is pressed against the concave surface and does not rotate under the action of external force. In addition, the pushing force of the compression spring 93 makes the switching knob 92 more stable.

[0047] When the signal source needs to be switched, the switching knob 92 is reversely rotated by an angle, taken out, and then enters the second layer concave ring 911 from the other group of straight grooves 912, and the principle is the same as above.

[0048] When one of the external signal source lines has a problem, the other signal source line is replaced in time.

[0049] The shell comprises a rear cover 8 and a main shell 1 which are connected together, a sealing ring 26 is arranged between the rear cover 8 and the main shell 1, and the sealing ring 26 has a waterproof function. The main shell 1 is symmetrically provided with elastic belt buckles 21 which can be stretched. One side of the main shell 1 is provided with a signal source inlet interface 12 and a signal source outlet interface 13. The rear cover 8 is provided with the first PCB 7 on the inner plate surface. The front surface of the main shell 1 is provided with a window, and the window is provided with a touch screen 2. The display screen 3, the pressing block 5 and the back plate 4 are sequentially arranged in the area between the touch screen 2 and the first PCB 7. The first PCB 7 is provided with a safety fence 6. The main shell 1 is further provided with a grounding screw 17.

[0050] In summary, the industrial-grade gateway device is convenient to operate: through the pressable and rotatable switching knob, the user can simply and intuitively realize the switching between different signal sources without complex operation process, professional tools and complex switching circuit, thereby greatly improving the convenience and efficiency of operation.

[0051] The industrial-grade gateway device has stable and reliable structure: the anti-disengagement structure formed by the convex strips and straight grooves between the switching knob and the annular member and the cooperation of the compression spring ensure the stability and reliability of the structure in the network switching process, and reduce the problem of unstable signal transmission caused by loose structure.

[0052] The industrial-grade gateway device has stable signal transmission: the one-to-one abutting conduction mode of the two groups of terminal groups and the elastic terminal groups can effectively ensure the accuracy and stability of signal transmission, reduce signal interference and loss, and meet the demand of high-reliability network connection in industrial environment.

[0053] The industrial-grade gateway device has multifunctional design structure: the retractable elastic belt buckle arranged on the casing facilitates the installation and fixation of the device; the signal source inlet interface and the signal source outlet interface facilitate the connection with external devices; the arrangement of the touch screen, the display screen and other components provides a good interactive interface for users, and improves the practicability and functionality of the device.

[0054] The industrial-grade gateway device has high safety: the safety fence arranged on the first PCB and the grounding screw in the main shell enhance the electrical safety of the device, effectively prevent electrical faults and safety accidents, and guarantee the safety of the device and personnel.

[0055] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation using the content of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
