Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular, relates to a distribution network communication channel switching gateway, a switching method and a system. Background Art

[0002] 5G gateways use the high bandwidth and low latency characteristics of 5G networks to provide more efficient and reliable communication guarantees for distribution networks. In distribution networks, a large number of devices require real-time monitoring and two-way information exchange, while traditional wireless communication methods have problems such as difficult connections and poor communication quality. The introduction of 5G gateways can significantly improve data transmission speed and response time, ensure the real-time and accuracy of various data in the distribution network, and thus meet the distribution network's high requirements for communication efficiency and reliability.

[0003] Traditional distribution network automation and other services usually use fiber optic switch networking to transmit data. In recent years, with the penetration of 5G in industrial scenarios, 5G can be used to complete data communication when there are no conditions for laying fiber optic cables.

[0004] For the power system, network security must be achieved. It requires that the devices accessing the fiber-optic private network and the devices accessing the 5G channel must be physically isolated. At present, the dual SIM card switching gateway is more commonly used. The gateway consists of a routing chip, a 5G module, and two SIM cards. The 5G module uses SIM card 1 to send and receive data. If the communication quality of SIM1 is poor, the 5G module switches to using SIM card 2 to register the network.

[0005] However, two SIM cards share one 5G module and one routing chip, so it is impossible to physically isolate the communication channels of the two SIM cards. Secondly, the switching logic is implemented inside the 5G module, and the 5G module does not have an Ethernet interface. It can only send data to the base station through 5G registration. Therefore, for northbound data, the 5G module cannot be connected to the distribution network fiber private network switch, and the switching function between the northbound fiber private network and the 5G channel cannot be realized.

When the fiber-optic private network channel is abnormal, the southbound interface is connected to the routing chip through a relay switch. The 5G module is used to provide 5G communication capabilities. When the fiber-optic private network channel is abnormal, the 5G module cooperates with the routing chip to complete data transmission. The southbound interface is used to connect to the distribution network service device. The southbound interface is connected to the relay switch. According to the control signal of the processor, the southbound interface switches the connection between the switching chip and the routing chip. The northbound interface is used to connect to the fiber-optic private network switch. The northbound interface is connected to the switching chip. When the fiber-optic private network channel is normal, the data of the northbound interface is exchanged through the switching chip.

[0028] Optionally, the relay switch is a mechanical multi-way selection switch.

[0029] Optionally, the processor uses a transmission control protocol for communication monitoring.

[0030] Optionally, the southbound interface and the northbound interface are RJ45 interfaces.

[0031] Specifically, the distribution network communication channel switching gateway consists of a southbound RJ45 port, a northbound RJ45 port, a relay switch, a CPU, a switching chip, a routing chip, and a 5G module.

[0032] The southbound RJ45 port is responsible for connecting to the distribution network service device.

[0033] The relay switch uses a physical on / off method to determine whether the circuit of the southbound RJ45 port is connected to the switching chip or the routing chip. It has two switch points, A and B, and only one switch point can be connected at the same time.

[0034] The switching chip is connected to point A of the relay switch to realize the data exchange function among the southbound RJ45 port, the northbound RJ45 port and the CPU.

[0035] The CPU determines whether the communication between the switching chip and the optical fiber private network switch of the distribution network is normal, and sends a switch instruction to the relay switch.

[0036] The northbound RJ45 port is connected to the fiber-optic private network switch to complete data sending and receiving.

[0037] The routing chip is connected to point B of the relay switch to complete the routing conversion between the 5G module and the distribution network service device.

[0038] The 5G module completes the registration of the SIM card and the 5G base station, and realizes the 5G data forwarding function.

[0039] Working principle design of distribution network communication channel switching gateway:

[0040] After the distribution network communication channel switching gateway is powered on, the relay switch is connected to the A connection point by default, that is, the exchange channel is used by default for data forwarding.

[0041] The CPU component uses ICMP protocol to communicate with the fiber private network switch IP: xxxx. It sends an ICMP message once per second. If it receives an ICMP response message from the fiber private network switch, it is determined that the fiber private network channel is normal, and the relay switch maintains the default A point connection point.

[0042] When the CPU component fails to receive a response message from the fiber private network switch IP: xxxx for three consecutive times, the CPU component determines that the fiber private network channel is abnormal. The CPU component sends a switch command to the relay switch, and the relay switch disconnects the A connection point and closes to the B connection point, so that the southbound RJ45 port is connected to the router component. The distribution network service device uses the 5G module to send data to the 5G base station through the router component, and completes communication with the distribution network master station through the 5G network.

[0043] When the relay switch is closed to the state of connection point B, the CPU component continues to send ICMP messages to the fiber private network switch IP: xxxx once a second. If the CPU component receives ICMP response messages from the fiber private network switch IP: xxxx three times in a row, it is determined that the fiber private network channel has returned to normal. The CPU component sends a switch command to the relay switch to close the connection point A and disconnect the connection point B.

Taking an electronic device as an example, the electronic device may include one or more processors and a memory for storing data. Optionally, the electronic device may also include a communication device and a display device for communication functions.

Among them, different processing units may be independent components or integrated into one or more processors. In some instances, the electronic device may also include one or more processors.

[0047] The memory can be used to store computer programs, such as storing a computer program corresponding to the distribution network communication channel switching method in the embodiment of the present invention, and the processor implements the above-mentioned distribution network communication channel switching method by running the computer program stored in the memory. The memory may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory may further include a memory remotely arranged relative to the processor, and these remote memories may be connected to the electronic device via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0048] The communication device is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the communication device includes a network adapter (network interface controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the communication device can be a radio frequency (radio frequency, RF) module, which is used to communicate with the Internet wirelessly. In some embodiments of the present solution, the communication device is used to connect to mobile devices such as mobile phones and tablets, and instructions can be sent to electronic devices through the mobile device.

[0049] The display device may be a touch screen type liquid crystal display (LCD) and a touch display (also referred to as a "touch screen" or "touch display screen"). The liquid crystal display may enable a user to interact with a user interface of the electronic device. In some embodiments, the electronic device has a graphical user interface (GUI), and a user may interact with the GUI by touching a finger release and / or gestures on a touch-sensitive surface, and executable instructions for executing the above-mentioned human-computer interaction functions are configured / stored in a computer program product or a readable storage medium executable by one or more processors.

[0050] Figure 2 is a flow chart of a method for switching a communication channel of a distribution network according to one embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0051] Step S101, obtaining the fiber private network channel status;

[0052] Step S102, in response to the state of the optical fiber private network channel being abnormal, controlling the relay switch to switch to the 5G communication channel;

[0053] Step S103, in response to the fiber private network channel state changing from abnormal to normal, controlling the relay switch to switch back to the fiber private network channel.

[0054] Optionally, obtaining the status of the fiber-optic private network channel includes: using a processor to send messages to the fiber-optic private network switch at preset time intervals and monitoring the response results; in response to the response result indicating that the processor has received the response message, determining that the status of the fiber-optic private network channel is normal; or, in response to the response result indicating that the processor has not received a response message for a preset number of consecutive sending cycles, determining that the status of the fiber-optic private network channel is abnormal.

[0055] Specifically, refer to Figure 3 , the specific implementation of the above method is as follows:

[0056] After the distribution network communication channel switching gateway is powered on, the relay switch is connected to the A connection point by default, that is, the exchange channel is used by default for data forwarding.

[0057] The CPU component uses ICMP protocol to communicate with the fiber private network switch IP: xxxx. It sends an ICMP message once per second. If it receives an ICMP response message from the fiber private network switch, it is determined that the fiber private network channel is normal, and the relay switch maintains the default A point connection point.

[0058] When the CPU component fails to receive a response message from the fiber private network switch IP: xxxx for three consecutive times, the CPU component determines that the fiber private network channel is abnormal. The CPU component sends a switch command to the relay switch, and the relay switch disconnects the A connection point and closes to the B connection point, so that the southbound RJ45 port is connected to the router component. The distribution network service device uses the 5G module to send data to the 5G base station through the router component, and completes communication with the distribution network master station through the 5G network.

[0059] When the relay switch is closed to the state of connection point B, the CPU component continues to send ICMP messages to the fiber private network switch IP: xxxx once a second. If the CPU component receives ICMP response messages from the fiber private network switch IP: xxxx three times in a row, it is determined that the fiber private network channel has returned to normal. The CPU component sends a switch command to the relay switch to close the connection point A and disconnect the connection point B.

[0060] It can be understood that by adopting the technical solution of the present invention, the distribution network service device can be connected to the fiber-optic private network channel and the 5G communication channel at the same time, and complete information transmission with the distribution network master station. The fiber-optic private network channel is used by default, and it can automatically switch to the 5G channel after the fiber-optic private network channel fails to communicate. After the fiber-optic private network channel returns to normal, it can automatically switch back to the fiber-optic private network channel. Secondly, the relay switch realizes the physical isolation of the two channels inside the gateway, meeting the security requirements and specifications of the distribution network for data transmission.

[0061] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method.
