Description

Technical Field

[0001] The utility model relates to a 5G CPE device, belonging to the technical field of customer-side terminals. Background Art

[0002] CPE (Customer Premises Equipment) is a bridge for communication between service terminals and mobile cellular base stations, mainly responsible for the upload and download of wireless signals. Different from the application scenarios of toC (consumer-grade) products with single communication functions, good operating environments, and low requirements for real-time reliability, the industrial field (including the power field) has higher requirements for CPE.

[0003] The existing patent, such as the Chinese utility model patent with the application number "202222480079.5", discloses a CPE device, including: a local area network interface, a communication module, a radio frequency module, an environment sensing module, and an interaction module; wherein, the local area network interface is used to connect the CPE device to the terminal device; the environment sensing module is used to monitor the business site environment to obtain environment sensing data; the interaction module is used to transmit the environment sensing data to the communication module, and after aggregating and converting the instructions from the upper control system, forward them to the terminal device. The instructions are operation instructions and / or control instructions formed by the upper control system in response to receiving the environment sensing data and analyzing and processing the environment sensing data; the communication module is connected to the local area network interface, the interaction module, and the radio frequency module, and is used to process the service data and / or environment sensing data of the terminal device into recognizable data of the communication network, and transmit the recognizable data to the radio frequency module; the radio frequency module is used to convert the recognizable data into a radio frequency signal and transmit the radio frequency signal to the network device. The environment sensing data can be transmitted to the upper control system, and the operation instructions and / or control instructions and other instructions from the upper control system are aggregated and converted and then forwarded to the terminal device, so that the terminal device can better execute various operation tasks.

[0004] Although the above-mentioned existing patent improves the interaction and environment perception capabilities of CPE, in industrial (including power) application scenarios, there are also various communication modes such as "terminal-master station" and "terminal-terminal", which require CPE to have flexible and rich internal and external network forwarding capabilities; some power service terminals (such as distribution network relay protection devices) also require an accurate time synchronization function, and it is a feasible and cost-reducing solution to provide accurate time synchronization by CPE; due to the accuracy requirements of management and security requirements such as anti-theft and anti-impersonation of terminals, CPE often needs to have a positioning function.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] It should be understood that the terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. As used in the specification of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include the plural forms.

[0043] The terms "comprising" and "including" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0044] The term "and / or" refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0045] See Figure 1 and Figure 2 , this embodiment provides a 5G CPE device, including a housing 1 and a circuit board 2 installed inside the housing 1;

[0046] The housing 1 includes a "U"-shaped bottom case 11, a first panel 12, a second panel 13, and a heat dissipation plate 14; the first panel 12 and the second panel 13 are respectively fixedly connected to both sides of the bottom case 11, and the heat dissipation plate 14 is fixedly connected to the top of the bottom case 11 to form a closed housing;

[0047] The circuit board 2 is fixed on the bottom case 11, specifically see Figure 3 , the overall circuit design of the circuit board includes a CPU module and a mobile cellular communication module, a WIFI module, a communication interface module, a power supply module, and an enhanced function module connected to the CPU module; in this embodiment, the CPU selects a domestic RK3568 chip, which is a mid - to - high - end low - power general - purpose SOC, using a 22nm manufacturing process, FCBGA636L package, integrating a 4 - core Arm architecture A55 processor and a Mali G52 2EE graphics processor. The RK3568 has rich function expansion interfaces, which can effectively improve the scalability of industry customization. The RK3568 supports PCIE3.0 1x2 / 2x1 Lanes and also supports PCIE2.1 1x1 Lane, meeting the expansion requirements of 4G / 5G, WIFI6, multi - network ports, NPU, etc. The RK3568 supports 3x SATA3.0, solving various instability problems of traditional AP processors' USB - extended SATA, supporting up to 4 USB ports, 1xUSB3.0 HOST + 1xUSB3.0 OTG + 2xUSB2.0 HOST.

Compared with an active crystal oscillator, it cannot start oscillation by itself and needs to rely on a clock circuit to generate an oscillation signal. Usually, when designing with a passive crystal oscillator, two load capacitors connected to the ground need to be connected to ensure that the circuit can oscillate continuously.

[0048] The input end of the mobile cellular communication module is connected to the SIM card module, and the output end is connected to the CPU module and the communication interface module. The SIM card module is used to insert a SIM card. In this embodiment, the mobile cellular communication module uses a 5G module or a 4G module. The 5G module can be a module of 5G Release 16 and previous versions, or a 5G RedCap lightweight module, or a module of later evolved versions. The SIM card module uses a USIM module, an eSIM module, or a combination of both.

[0049] In one embodiment, the mobile cellular communication module selects a 5G module, and the buses for the CPU and the 5G module to communicate are the UART and PCIE3.0 buses.

[0050] The UART (Universal Asynchronous Receiver-Transmitter) is usually used for inter-board communication. The signals are mainly two lines, TXD and RXD. The transmission rate generally does not exceed 20 kbps. The rate depends on the baud rate. Commonly used baud rates are 9600 bps (1.2 KB / s) and 115200 bps (14.4 KB / s). The rate is low, the anti-interference ability is poor, and the maximum transmission distance does not exceed 15 m.

[0051] The PCIE3.0 bus usually has PCIE3.0 X1 / X4 / X8 / X16, and the transmission rate is 8 GT / s. The corresponding bandwidths are 984.6 MB / s, 3.938 GB / s, 7.877 GB / s, and 15.754 GB / s respectively. In this design, PCIE3.0 X1 is used, and the corresponding bandwidth is 984.6 MB / s. The key signals of PCIE3.0 X1 are 1 group of reference clock differential signals, 1 group of transmission differential signals, and 1 group of reception differential signals. The key signals of PCIE3.0 X4 are 1 group of reference clock differential signals, 4 groups of transmission differential signals, and 4 groups of reception differential signals. The same applies to PCIE3.0 X8. When a large amount of data is required during the communication between the CPU and the module and a high rate is required, the PCIE bus is usually used. In this embodiment, according to the CPU bus resources, the PCIE3.0 X1 bus is selected. For the specific circuit diagram of the mobile cellular communication module in this embodiment, see Figure 4 。

[0052] The input end of the WIFI module is connected to the CPU module, and the output end is connected to the communication interface module; the buses used for communication between the CPU and the WIFI module are the UART (Universal Asynchronous Receiver-Transmitter) and the PCIE2.0 transmission line. The UART is usually used for inter-board communication. The signals are mainly the two lines of TXD and RXD. The transmission rate generally does not exceed 20 kbps. The rate depends on the baud rate. Commonly used baud rates are 9600 bps (1.2 KB / s) and 115200 bps (14.4 KB / s). The rate is low, the anti-interference ability is poor, and the maximum transmission distance does not exceed 15 m. The PCIE2.0 transmission line usually has PCIE2.0 X1 / X4 / X8 / X16, and the transmission rate is 5 GT / s. The corresponding bandwidths are 500 MB / s, 2 GB / s, 4 GB / s, and 8 GB / s respectively. In this embodiment, PCIE2.0 X1 is used, and the corresponding bandwidth is 500 MB / s. The key signals of PCIE2.0 X1 include 1 group of reference clock differential signals, 1 group of transmit differential signals, and 1 group of receive differential signals. The key signals of PCIE2.0 X4 include 1 group of reference clock differential signals, 4 groups of transmit differential signals, and 4 groups of receive differential signals. The same applies to PCIE2.0 X8. When a large amount of data is required for communication between the CPU and the module and a high rate is required, the PCIE bus is usually used. In this embodiment, according to the CPU bus resources, the PCIE2.0 X1 bus is selected. Figure 5 This is the specific circuit diagram of the WIFI module in this embodiment.

[0053] The communication interface module includes several communication interfaces that provide network communication functions to the outside; in this embodiment, the communication interfaces include RS485 interface, RS232 interface, RJ45 network port, fiber optic interface, 4G / 5G interface, WIFI interface and other communication interfaces. Based on the above interfaces, different technical solutions such as NAT (Network Address Translation), passthrough, DMZ (Demilitarized Zone), and tunneling are supported to meet the communication forwarding requirements and security requirements of different power services.

[0054] The power supply module supplies power to the electrical components in circuit board 2; in this embodiment, the power supply module includes an external power supply module and a PoE (Power over Ethernet) module. The input of the external power supply module is set to DC 9 - 36V, and the physical form is a 3PIN anti-drop phoenix terminal. To increase power supply reliability, 2 power terminals are set in this embodiment. When one power supply fails unexpectedly, the other can also supply power to the device. The power input passes through a soft start circuit to reduce the impact, and then passes through a common mode filter and is sent to the subsequent DC-DC power supply. The specific circuit of the external power supply module is as Figure 6 shown. The PoE module uses the RK809-5 power management chip as the core to complete the power supply of the PoE device.

[0055] The enhanced function module can adopt only the positioning module, or only the timing module, or both the positioning and timing modules. In this embodiment, the enhanced function module includes a positioning module and a timing module. The positioning module includes a receiving antenna and a GNSS satellite positioning module. The output end of the receiving antenna is connected to the input end of the GNSS satellite positioning module, which is used to receive GNSS satellite positioning signals and output them to the GNSS satellite positioning module. The output end of the GNSS satellite positioning module is connected to the CPU module, which is used to condition the GNSS satellite signals and output them to the CPU module. The timing module includes a GNSS satellite timing data receiving module, a mobile cellular communication timing data receiving module, and an electrical B-code timing output module. The input end of the GNSS satellite timing data receiving module is connected to the receiving antenna, and the output end is connected to the electrical B-code timing output module, which is used to receive GNSS satellite timing data through the receiving antenna and send it to the electrical B-code timing output module. The input end of the mobile cellular communication timing data receiving module is connected to the mobile cellular communication module, and the output end is connected to the electrical B-code timing output module, which is used to receive mobile cellular communication timing data and send it to the electrical B-code timing output module. The output end of the electrical B-code timing output module is connected to the CPU module, which is used to output a timing signal to the CPU module through the electrical B-code.

[0056] In this embodiment, the timing module can be timed through the GNSS satellite timing data receiving module and the internal crystal oscillator, or it can receive the time information sent by the 5G network through the mobile cellular communication timing data receiving module for timing.

[0057] In this embodiment, the GNSS satellite positioning module is a Beidou / GPS module, which can receive Beidou satellite signals and GPS satellite signals. The selected Beidou / GPS module is the UM220-IV M0 industrial-grade multi-system GNSS navigation and positioning module of Huixin Xingtong. The Beidou / GPS signals are received through the antenna and given to the Beidou / GPS module. The signals are processed inside the module and communicate with the CPU module through the UART serial port. The CPU module obtains the longitude and latitude information by parsing the data of the Beidou / GPS module, thereby realizing the positioning function. The circuit of the Beidou / GPS module is specifically as Figure 7 shown.

[0058] As a preferred implementation manner of this embodiment, the enhanced function module further includes an encryption module. The encryption module is bidirectionally communicatively connected to the CPU module, which is used to encrypt the data transmitted from the CPU module to the encryption module and return it to the CPU module. The buses used for communication between the CPU module and the encryption module are the SPI bus and the USB3.0.

[0059] The SPI bus has a total of 4 lines and generally operates in a master-slave mode, including MISO (Master In Slave Out), MOSI (Master Out Slave In), SCLK (Clock), and CS (Chip Select). SPI is a full-duplex synchronous transmission with a rate of approximately 50 Mbps. When multiple SPI devices are connected, selection is based on the CS signal. Whichever CS enable signal is at a low level enables that SPI device. In this design, there is only one SPI device, and the default CS is at a high level (no communication). When CS is pulled low, the CPU will communicate with the slave device via SPI.

[0060] The USB3.0 has a total of 8 lines, including 5V power, GND, DP / DM, transmit TX±, and receive RX±. Usually, the USB3.0 transmission rate is 5 Gbps. When the CPU communicates with the slave device and there is a large amount of data and high rate requirements, high-speed buses are usually used, such as USB3.0, PCIE, SATA, etc. Considering CPU resources, USB3.0 is used in this embodiment.

[0064] The isolation chip uses an IS3642 integrated chip to implement an isolated UART5 serial port signal through the isolation chip. The isolation chip and its peripheral circuit are specifically as Figure 9 shown.

[0065] As a preferred implementation manner of this embodiment, hanging ears 15 are also fixedly connected to the outer walls at both ends of the bottom case 11, enabling this device to be suitable for installation in various positions such as the inner wall and partition of a cabinet through the hanging ears 15.

"And / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent the cases of A existing alone, A and B existing simultaneously, and B existing alone. Where A and B may be singular or plural.
