Description

Technical Field

[0001] The present invention belongs to the technical field of gateway interfaces, and more specifically, particularly relates to an expandable interface of a communication gateway based on energy Internet of Things. Background Art

[0002] The energy Internet of Things communication gateway is a device that plays a key role in the energy Internet of Things system. It collects data from various energy devices, including energy consumption, production, status and other information, and transmits the collected data to the energy management system or cloud server through different communication protocols to achieve centralized data management and analysis. The energy Internet of Things communication gateway interface can connect different types of energy devices to realize the collection of energy data. The gateway interface generally has the following structure:

[0003] 1. Interface type: The gateway interface can adopt a variety of physical connection methods, the common ones are Ethernet interface, serial port, USB interface, etc.;

[0004] 2. Connector: Depending on the interface type, use the corresponding connector for physical connection;

[0005] 3. Cables: The cables used to connect the gateway and external devices will also affect the performance of the interface.

[0006] The Chinese patent publication number is: CN212676555U, a network interface for an Internet of Things gateway. The Internet of Things technology gateway integrates the network card interface into the circuit board structure, making the network card interface convenient and practical to connect. The "convex" shape and the structure with a guide groove allow the network card interface to be installed side by side with a small intelligent circuit breaker in the meter box, making it suitable for various installation environments and greatly improving the adaptability of the product.

[0007] Existing IoT gateways have the following disadvantages when in use:

[0008] 1. The existing IoT gateway will use an external converter to expand the interface. However, when the expansion interface on the converter is damaged by abnormal current, the existing gateway interface cannot cut off the connection in time. When the power supply on the interface is abnormal, excessive voltage, current or other abnormal conditions may be generated, which may damage the connected devices. When the power supply is abnormal, leakage, short circuit and other conditions may occur, which may cause electric shock to people who come into contact with the equipment.

[0009] 2. When the existing IoT gateway is expanding its interface, no fixing device is set for the external converter plug. During daily placement or transportation, if the gateway plug does not have a protective structure, it is easy to be collided and squeezed, which may cause the plug to deform, damage the internal metal contacts or wires, and affect the normal use of the plug.

[0010] In view of this, the existing structure and deficiencies are studied and improved, and an expandable interface of a communication gateway based on the energy Internet of Things is provided, in order to achieve a more practical purpose. Summary of the invention

DETAILED DESCRIPTION

[0030] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] See also Figure 1 - Figure 8The present invention provides an expandable interface of a communication gateway based on the energy Internet of Things, including a communication chassis 1 and a main interface 11. The communication chassis 1 is provided with an expansion mechanism for facilitating the expansion of the interface, and the communication chassis 1 is provided with a detection mechanism for facilitating the use of the expansion mechanism. The expansion mechanism includes a converter 5, a main plug 6, a C-shaped protective box 7, a pull plate 8 and an arc rod 9. The detection mechanism includes a motor 2, a signal converter 3 and an electrical signal detector 4. The motor 2 is located at the side end of the communication chassis 1, and an L-shaped fixing rod 21 is fixedly installed between the motor 2 and the communication chassis 1. The switch 3 is fixedly mounted on the side end of the communication chassis 1, the number of the electric signal detectors 4 is three, each of the electric signal detectors 4 is fixedly mounted on the lower end of the converter 5, the converter 5 is fixedly mounted on the side end of the communication chassis 1, the main plug 6 is slidably mounted on the inner side wall of the C-shaped protective box 7, the lower end of the C-shaped protective box 7 is fixedly mounted with a rotating rod 74, the side end of the L-shaped fixed rod 21 is penetrated with a rectangular slide groove 22, the output end of the motor 2 is fixedly mounted with a threaded rod 26, and a push rod 23 is also provided on one side of the motor 2, and the side end of the push rod 23 is penetrated with a The threaded groove 24, the threaded rod 26 is threadedly mounted on the inner side wall of the threaded groove 24, the side end of the push rod 23 is also fixedly mounted with a sliding rod 25, and the sliding rod 25 is slidably mounted on the inner side wall of the rectangular slide groove 22, and the upper end of the signal converter 3 is fixedly mounted with three connectors 31, each connector 31 is electrically connected to each electrical signal detector 4, and a first connecting line 32 is also fixedly mounted between the signal converter 3 and the motor 2, and a detection probe 41 is fixedly mounted on the upper end of each electrical signal detector 4, the motor 2, the signal converter 3 and the electrical signal detector When the electric signal detector 4 detects that a certain expansion port 51 is damaged, the motor 2 can be driven to start and drive the push rod 23 to move, so that the connection between the main plug 6 and the main interface 11 is disconnected, so as to avoid the expansion port 51 being damaged and generating excessive voltage, current or other abnormal conditions, which may damage the connected equipment or the communication chassis 1 through the main interface 11. When the expansion port 51 is damaged, the present application can timely cut off the connection between the main plug 6 and the main interface 11, so as to avoid further damage to the equipment by abnormal power supply, and reduce the risk of equipment damage;

[0032] The converter 5 is provided with three expansion ports 51, and each detection probe 41 is fixedly installed on the inner side wall of the expansion port 51. Two vertical plates 52 are fixedly installed on the upper end of the converter 5, and the side ends of the two vertical plates 52 are penetrated with a first circular groove 53, and the side ends of the vertical plates 52 are also penetrated with a plurality of limiting grooves 54, and each limiting groove 54 is distributed in an array at the circumferential end of the first circular groove 53. A second connecting line 55 is electrically connected between the converter 5 and the main plug 6. After the converter 5 is turned on and used, each electrical signal detector 4 can detect the use of each expansion port 51 in real time through the detection probe 41. The detection probe 41 on the electrical signal detector 4 is generally in contact with the signal pin in the expansion port 51. When the expansion port 51 is used, there is usually a specified working voltage range. Similarly, there is also a normal current range when the expansion port 51 is used. The electrical signal detector 4 can detect the use of each expansion port 51 in real time. Monitor the voltage and current at the expansion port 51. If the voltage or current exceeds the normal range, it may indicate that the expansion port 51 may be damaged. At this time, after the electrical signal detector 4 receives a signal exceeding the use threshold, it will drive the motor 2 to start through the signal converter 3 and the first connecting line 32. The start of the motor 2 will drive the threaded rod 26 to rotate. The rotation of the threaded rod 26 will drive the push rod 23 to move through the thread groove 24. When the push rod 23 moves and contacts the rotating rod 74, it will drive the rotating rod 74 to move. The movement of the rotating rod 74 will compress the first spring 77. The movement of the rotating rod 74 will also drive the main plug 6 in the C-shaped protective box 7 to move away from the main interface 11. Therefore, when a certain expansion port 51 on the converter 5 is damaged, the connection with the main interface 11 is disconnected. The user can quickly find out the damaged expansion port 51 according to the abnormal value displayed on the electrical signal detector 4 and perform maintenance on it.

[0033] A cross bar 61 is fixedly installed on the side end of the main plug 6, and two slots 62 are penetrated at the upper end of the cross bar 61. An L-shaped vertical rod 71 is fixedly installed on the side end of the C-shaped protective box 7. A movable groove 72 is penetrated at the side end of the L-shaped vertical rod 71. The cross bar 61 is slidably installed on the inner side wall of the movable groove 72. A connecting groove 73 is penetrated at the upper end of the L-shaped vertical rod 71. A plug plate 82 is slidably installed on the inner side wall of the connecting groove 73. The end of the plug plate 82 is located on the inner side wall of the slot 62. The plug plate 82 is fixedly installed on the lower end of the pull plate 8. A second spring 81 is fixedly installed between the pull plate 8 and the L-shaped vertical rod 71. A second circular groove 75 is fixedly installed on the side end of the rotating rod 74. The rotating rod 74 is slidably installed on the adjusting shaft 7 through the second circular groove 75. The first spring 77 is fixedly installed between the circumferential end of the rotating rod 74 and the vertical plate 52. The first spring 77 is located at the circumferential end of the adjusting shaft 76, which is the state after the rotating rod 74 is erected. The rotation of the rotating rod 74 will also drive the main plug 6 in the C-shaped protective box 7 to move. When the main plug 6 and the main interface 11 are in a coincident state, the user can release the arc rod 9 at this time, and the third spring 92 will rebound and pull the arc rod 9 to reset, thereby driving the limiting column 91 on the arc rod 9 to be inserted into the limiting groove 54 again to complete the adjustment of the main plug 6. The user can pull the pull plate 8 upwards. After the pull plate 8 moves upwards and leaves the inner wall of the slot 62, the user can push the cross bar 61 to move in the movable groove 72 and drive the main plug 6 to move and insert it into the main interface 11. When the cross bar 61 moves, it will drive another slot 62 and the connecting slot 73 to overlap. After the main plug 6 is inserted into the main interface 11, the user can loosen the arc rod 9, so that the second spring 81 rebounds and drives the plug plate 82 on the pull plate 8 to be inserted into the slot 62 again, so as to limit and fix the main plug 6, thereby ensuring the stability of the main plug 6 when in use;

[0034] A third spring 92 is fixedly installed between the arc rod 9 and the adjusting shaft 76, and a telescopic rod 93 is also fixedly installed between the arc rod 9 and the adjusting shaft 76. Two limit columns 91 are fixedly installed on the side end of the arc rod 9, and the two limit columns 91 are slidably installed on the inner wall of the limit groove 54. When it is necessary to expand the interface on the communication chassis 1, the user can pull the arc rod 9, and the movement of the arc rod 9 will drive the two limit columns 91 to move. At this time, the third spring 92 and the telescopic rod 93 are stretched. When the limit column 91 moves away from the inner wall of the limit groove 54, the user can rotate the arc rod 9. The rotation of the arc rod 9 drives the adjusting shaft 76 to rotate through the third spring 92 and the telescopic rod 93. The rotation of the adjusting shaft 76 drives the rotating rod 74 to rotate. When the arc rod 9 is rotated to ninety degrees, the rotating rod 74 is in an upright state.

[0035] Working principle:

[0036] The first step is to increase the capacity expansion interface in the energy Internet of Things to adapt to the growing device connection needs and data transmission volume. With the development of the energy system, there may be more and more sensors, smart devices, etc. that need to be connected to the communication gateway. The expandable interface can easily add new connection ports or upgrade the capacity of the existing interface to ensure the flexibility and scalability of the system. When the main interface 11 on the communication chassis 1 is used, it can be used alone when it does not need to be expanded. When expansion is required, the rotation rod can be adjusted to 74 to ninety degrees. The state after rotation is as shown in the attached figure. Figure 1 As shown, the main plug 6 is inserted into the main interface 11, thereby expanding the interface, and the user can plug more interfaces into the expansion port 51 for use;

[0037] In the second step, when the interface on the communication chassis 1 needs to be expanded, the user can pull the arc rod 9. The movement of the arc rod 9 will drive the two limit posts 91 to move. At this time, the third spring 92 and the telescopic rod 93 are stretched. When the limit post 91 moves away from the inner wall of the limit slot 54, the user can rotate the arc rod 9. The rotation of the arc rod 9 drives the adjustment shaft 76 to rotate through the third spring 92 and the telescopic rod 93. The rotation of the adjustment shaft 76 drives the rotation rod 74 to rotate. When the arc rod 9 is rotated to ninety degrees, the rotation rod 74 is in an upright state. Figure 1 and attached Figure 2 The figure shows the state after the rotating rod 74 is erected. The rotation of the rotating rod 74 will also drive the main plug 6 in the C-shaped protective box 7 to move. When the main plug 6 and the main interface 11 are in a superimposed state, the user can loosen the arc rod 9 at this time, and the third spring 92 will rebound and pull the arc rod 9 to reset, thereby driving the limiting column 91 on the arc rod 9 to be inserted into the limiting groove 54 again, completing the adjustment of the main plug 6. The user can pull the pull plate 8 upward. After the pull plate 8 moves upward and leaves the inner side wall of the slot 62, the user can push the cross bar 61 to move in the movable slot 72 and drive the main plug 6 to move and insert it into the main interface 11. When moving, the cross bar 61 will drive another slot 62 and the connecting slot 73 to be in a superimposed state. After the main plug 6 is inserted into the main interface 11, the user can loosen the arc rod 9, so that the second spring 81 rebounds and drives the plugging plate 82 on the pull plate 8 to be inserted into the slot 62 again, to limit and fix the main plug 6, and ensure the stability of the main plug 6 when in use;

[0038] The device is provided with a main plug 6, a second connecting line 55 and a converter 5, and when the expansion port 51 is not needed, the main interface 11 can be used alone. When the expansion port 51 is needed, the main plug 6 can be adjusted to be inserted into the main interface 11, and then each expansion port 51 on the converter 5 is connected. By expanding the interface on the communication chassis 1, the communication chassis 1 can be connected to more sensors, actuators, controllers and other devices, meeting the needs of the development of the Internet of Things and digitalization, and realizing the connection of multiple devices;

[0039] The device is provided with a pull plate 8, a main plug 6, a cross bar 61 and a slot 62, and when the main plug 6 is inserted into the main interface 11 for use, the plug plate 82 on the pull plate 8 can be clamped on the inner wall of the slot 62 to limit and fix the main plug 6, which can effectively prevent the main plug 6 from being loose during daily use. By limiting the main plug 6, the main plug 6 can be tightly fixed to maintain good contact with the main interface 11, ensuring the stability of data transmission and power supply;

[0040] The device is provided with a C-shaped protection box 7. When the main plug 6 is not needed, the main plug 6 can be located in the C-shaped protection box 7, thereby protecting the main plug 6 when it is not in use. The main plug 6 without protection is subject to collision and extrusion, which may cause the main plug 6 to deform, damage the internal metal contacts or wires, and affect the normal use of the main plug 6. The provision of the C-shaped protection box 7 can effectively protect the main plug 6 from the influence of these external forces and extend the service life of the main plug 6.

[0041] In the third step, after the converter 5 is turned on, each electrical signal detector 4 can detect the usage of each expansion port 51 in real time through the detection probe 41. The detection probe 41 on the electrical signal detector 4 is generally in contact with the signal pin in the expansion port 51. When the expansion port 51 is used, there is usually a specified working voltage range. Similarly, there is also a normal current range when the expansion port 51 is used. The electrical signal detector 4 can monitor the voltage and current at the expansion port 51 in real time. If the voltage or current exceeds the normal range, it may indicate that the expansion port 51 may be damaged. At this time, the electrical signal detector 4 will convert the signal into a signal after receiving a signal that exceeds the usage threshold. The machine 3 and the first connecting line 32 drive the motor 2 to start, and the motor 2 starts to drive the threaded rod 26 to rotate. The rotation of the threaded rod 26 drives the push rod 23 to move through the thread groove 24. When the push rod 23 moves and contacts the rotating rod 74, it drives the rotating rod 74 to move. The movement of the rotating rod 74 compresses the first spring 77. The movement of the rotating rod 74 also drives the main plug 6 in the C-shaped protective box 7 to move away from the main interface 11. Therefore, when a certain expansion port 51 on the converter 5 is damaged, the connection with the main interface 11 is disconnected. The user can quickly find out the damaged expansion port 51 according to the abnormal value display on the electrical signal detector 4 and perform maintenance on it.

[0042] The device is provided with a motor 2, a signal converter 3 and an electric signal detector 4 to cooperate. When the electric signal detector 4 detects that a certain expansion port 51 is damaged, the motor 2 can be driven to start and drive the push rod 23 to move, so that the connection between the main plug 6 and the main interface 11 is disconnected, so as to avoid the expansion port 51 being damaged and generating excessive voltage, current or other abnormal conditions, which may cause damage to the connected equipment or the communication chassis 1 through the main interface 11. When the expansion port 51 is damaged, the present application can timely cut off the connection between the main plug 6 and the main interface 11, so as to avoid further damage to the equipment by abnormal power supply and reduce the risk of equipment damage;

[0043] The device is provided with an electrical signal detector 4, which detects the current and voltage on each expansion port 51 in real time. When a certain expansion port 51 on the converter 5 is damaged, the device can quickly find out which expansion port 51 is damaged by observing the current signal data displayed on the electrical signal detector 4, thereby realizing accurate and rapid maintenance without the need to detect and troubleshoot one by one, thereby improving the maintenance efficiency of the expansion port 51.
