Description

Technical Field

[0001] The present invention relates to the technical field of interface gateways, and particularly to a fully domestic in-vehicle integrated service gateway device. Background Art

[0002] In integrated service usage scenarios, various types of interfaces and protocols are involved, such as E1, FXO\FSO, Ethernet, synchronous and asynchronous interfaces, etc. Building an integrated service network that supports multiple network protocols and interfaces such as E1, FXO / FSO, and SIP requires multiple types of network devices to work together. These devices not only need to provide corresponding physical interfaces at the hardware level but also need to implement protocol conversion and other operations at the software level to ensure seamless connection between different communication systems.

[0003] Currently, traditional solutions have complex networks and low efficiency: Building an integrated service network using multiple devices with different physical interfaces indeed faces many challenges, including increased network complexity, higher latency, and lower reliability. For example, to achieve communication between E1 and the IP network, an E1 protocol converter is needed to convert the E1 signal into a packet format suitable for IP network transmission. Similarly, when it comes to the conversion between analog and digital signals, specific conversion devices such as FXO / FXS gateways are also required; High network maintenance cost: Building a network using multiple devices with different physical interfaces increases the difficulty of network configuration and management, and also raises the cost of troubleshooting; Low reliability: When building a network using multiple devices with different physical interfaces, there will be a problem of too many connecting lines, which not only increases the complexity of network cabling but also significantly increases the probability of failures. In addition, most of the general-purpose devices on the market do not meet the technical requirements of vehicles, such as the requirements of withstanding strong vibrations and impacts. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to provide a fully domestic in-vehicle integrated service gateway device to solve the problems in the background art.

[0005] Technical Solution: A fully domestic in-vehicle integrated service gateway device described in the present invention includes: a main control service board, an LED sub-board, an FXO / FXS sub-board, an E1 sub-board, a network port / asynchronous sub-board, and a PTT / V35 synchronous interface sub-board; among them, the LED sub-board, the FXO / FXS sub-board, the E1 sub-board, the network port / asynchronous sub-board, and the PTT / V35 synchronous interface sub-board are all connected to the main control service board through VPX connectors.

[0006] Furthermore, the main control service board provides a network port, a serial port, and an LED externally; provides protocol processing functions and data forwarding functions for each sub-board, enabling the data of each sub-board to communicate with each other.

[0007] Further, the LED daughter board is an LED matrix, which defines various meanings for each LED indicator and displays the device status during the device operation stage; the data of the LED daughter board is communicated through the I2C bus to control each LED lamp.

[0008] Further, the E1 daughter board is an E1 relay daughter board, which is implemented by a domestic E1 interface chip; among them, each RJ48C contains two E1s, and a total of eight E1s in four RJ48Cs.

[0009] Further, the FXS / FXO daughter board includes two groups of single-channel internal and external line FXS / FXO modules. After the signal is relayed by the FPGA, it is forwarded to the main control service board for processing through the PCIE bus; the FXS / FXO interface module in the FXS / FXO daughter board mainly consists of two parts: the codec unit and the physical electrical interface part; the codec includes ADC and DAC.

[0010] Further, the network port / asynchronous interface daughter board provides the device with network port access capability and asynchronous interface access capability.

[0011] Further, the data processing process of the network port / asynchronous interface daughter board is as follows: after the network port / asynchronous interface daughter board receives the signal from the asynchronous terminal device, it performs level conversion and protocol decoding on the signal; then it sends the data to the main control service board. After the main control service board receives the data, it performs data processing and protocol conversion on the data; after the data processing is completed, it selects the specified sending port according to the user configuration and sends the data to the network port / asynchronous interface daughter board. After the network port / asynchronous interface daughter board receives the returned data, it performs protocol encoding and level forwarding on the data, and then sends it to the asynchronous terminal device to complete a terminal data sending and receiving operation; different from the data forwarding between asynchronous devices, after the main control service board receives the asynchronous serial port data, it encapsulates the data into the TCP / IP protocol, and then sends the data to the asynchronous interface daughter board through the network port. The asynchronous interface daughter board forwards the data to the external network port terminal device to complete the data communication between the asynchronous device and the network port device.

[0012] Further, the PTT / V35 synchronization interface daughter board is used to provide 8 groups of V.35 interfaces externally, and the PTT / V35 synchronization interface daughter board is connected to the DTE terminal device through the V.35 interface.

[0013] Furthermore, the data processing process of the PTT / V35 synchronization interface daughter board is as follows: After receiving the data signal from the external DTE terminal device, the PTT / V35 synchronization interface daughter board first completes level conversion, data sampling, and encoding, and then submits the data to the buffer queue. The sending module of the synchronization interface daughter board encapsulates the data in the buffer queue and the port information of the DTE terminal into Ethernet MAC frame data and sends it to the main control service board; after receiving the MAC frame data from the synchronization interface daughter board, the main control service board submits the data to the protocol stack software for processing; the main control service board performs protocol conversion, service data processing, and service data statistics on the data, and then according to the configuration information selected by the user port, sends the data to the specified other port, and encapsulates the service data and the specified port information into the original MAC frame format and sends it back to the synchronization interface daughter board; after receiving the data returned by the service main board, the synchronization interface daughter board parses the MAC frame data, extracts the port information therein, and then decodes and converts the level of the service data, and then sends the data to the DTE terminal device of the specified port.

[0014] Furthermore, the data processing process of the FXS / FXO daughter board is as follows. The FXS / FXO daughter board receives the analog signal of the external FXO / FXS terminal, performs data sampling and encoding on the analog signal, and then stores the data after A / D conversion in the interface buffer queue; the sending module of the interface daughter board sends the data to the main control service board through the PCIE bus for data processing and protocol conversion; after the service data is processed, through the IP address information configured by the user, the data is encapsulated with the TCP / IP protocol, and then the data is sent to the FXO / FXS daughter board through the network port; after receiving the data, the FXO / FXS daughter board performs buffering, decoding, etc. on the data, and finally sends the data to the external IP terminal device.

Detailed implementation manners

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0018] As Figure 1 shown, an all-domestic vehicle-mounted integrated service gateway device is provided in an embodiment of the present invention, which is characterized by including: a main control service board, an LED daughter board, an FXO / FXS daughter board, an E1 daughter board, a network port / asynchronous daughter board, and a PTT / V35 synchronization interface daughter board; wherein, the LED daughter board, the FXO / FXS daughter board, the E1 daughter board, the network port / asynchronous daughter board, and the PTT / V35 synchronization interface daughter board are all connected to the main control service board through a VPX connector.

[0019] Among them, as Figure 2 shown, the main control service board provides a network port, a serial port, and an LED externally; provides protocol processing functions and data forwarding functions for each daughter board, enabling the data of each daughter board to communicate with each other.

[0020] As Figure 3 shown, the analog voice data of the FXO / FXS daughter board is sent to the main control service board through PCIE after being processed. The main control service board analyzes and processes the data, and then sends the data to other main boards such as the network port daughter board.

[0021] As Figure 4As shown, the LED daughter board is an LED matrix, which defines various meanings for each LED indicator and displays the device status during the device operation stage; the data of the LED daughter board communicates through the I2C bus to control each LED lamp.

[0022] As Figure 5 shown, the LED daughter board data processing flow is as follows: the LED lamp board receives the control of the service main board, receives the control data of the service main board through the I2C bus, and then lights or turns off the specified LED lamp according to the control data. The information acquisition module of the main control service board acquires system data information, such as power supply and functional daughter board port information, and then calls the I2C read / write interface of the system to write the control information into the CPLD of the service main board. The CPLD then forwards the data to the LED daughter board through the external I2C bus. The LED matrix control chip of the LED daughter board analyzes the received control signal, and then the specified LED lamp lights, turns off, and flashes.

[0023] As Figure 6 shown, the E1 daughter board is an E1 relay daughter board, which is implemented by a domestic E1 interface chip; among them, each RJ48C contains two E1s, and a total of eight E1s in four RJ48Cs.

[0024] As Figure 7 shown, after the E1 interface receives the signal, it is first processed by the E1 interface chip for data sampling and protocol decoding, and then the processed data is submitted to the FPGA chip. The FPGA chip then sends the data to the main control service board through the PCIE bus. After the main control service board receives the data, it processes the data and performs protocol conversion; after the data processing is completed, data encapsulation is performed, and the data is encapsulated into a TCP / IP protocol packet, and the IP address uses the IP address configured by the user, and then the data is sent to the network port / asynchronous interface daughter board. After the network port / asynchronous interface daughter board receives the returned data, it performs protocol encoding and level forwarding on the data, and then sends it to the RJ45 network port terminal device to complete a terminal data transceiver operation.

[0025] As Figure 8 shown, the network port / asynchronous interface daughter board provides the device with network port access capabilities and asynchronous interface access capabilities.

[0026] As Figure 9As shown in the figure, the data processing process of the network port / asynchronous interface daughter board is as follows: After receiving the signal from the asynchronous terminal device, the network port / asynchronous interface daughter board performs level conversion and protocol decoding on the signal; then it sends the data to the main control service board. After receiving the data, the main control service board processes the data and performs protocol conversion; after the data processing is completed, it selects the specified sending port according to the user configuration and sends the data to the network port / asynchronous interface daughter board. After receiving the returned data, the network port / asynchronous interface daughter board performs protocol encoding and level forwarding on the data, and then sends it to the asynchronous terminal device, completing one round of terminal data sending and receiving.

[0027] As Figure 14 shown, the asynchronous / network port daughter board provides asynchronous interface and network port access capabilities externally. Like other functional daughter boards, the data of each interface needs to be forwarded to the main control service board for data processing and protocol conversion, and then the data is forwarded to other terminal devices according to the user configuration. The convergence gateway device uses the asynchronous / network port daughter board to support the forwarding of asynchronous interfaces to network port terminals. Different from the data forwarding between asynchronous interfaces, after receiving the asynchronous serial port data, the main control service board needs to encapsulate the data into the TCP / IP protocol, and then send the data to the asynchronous interface daughter board through the network port. The asynchronous interface daughter board forwards the data to the external network port terminal device, completing the data communication between the asynchronous device and the network port device.

[0028] As Figure 10 shown, the FXS / FXO daughter board includes two groups of single-channel internal and external line FXS / FXO modules. After the signal is relayed by the FPGA, it is forwarded to the main control service board for processing through the PCIE bus; the FXS / FXO interface module in the FXS / FXO daughter board mainly consists of two parts: the encoding and decoding unit and the physical electrical interface part; among them, the encoding and decoding includes ADC and DAC.

[0029] As Figure 11 shown, the data processing process of the FXS / FXO daughter board is as follows: The FXS / FXO daughter board receives the analog signal from the external FXO\FXS terminal, performs data sampling and encoding on the analog signal, and then stores the data after A / D conversion in the interface buffer queue; the sending module of the interface daughter board sends the data to the service main board through the PCIE bus for data processing and protocol conversion; after the service data is processed, it performs TCP / IP protocol encapsulation on the data according to the IP address information configured by the user, and then sends the data to the FXO / FXS daughter board through the network port; after receiving the data, the FXO / FXS daughter board performs buffering, decoding and other operations on the data, and finally sends the data to the external IP terminal device. As Figure 12 shown, the PTT / V35 synchronous interface daughter board is used to externally provide 8 groups of V.35 interfaces. The PTT / V35 synchronous interface daughter board is connected to the DTE terminal device through the V.35 interface.

[0030] As Figure 13 shown, the data processing process of the PTT / V35 synchronous interface daughter board is as follows: After receiving the data signal from the external DTE terminal device, the PTT / V35 synchronous interface daughter board first completes level conversion, data sampling, and encoding work, and then submits the data to the buffer queue. The sending module of the synchronous interface daughter board encapsulates the data in the buffer queue and the port information of the DTE terminal into Ethernet MAC frame data and sends it to the main control service board; After receiving the MAC frame data of the synchronous interface daughter board, the main control service board submits the data to the protocol stack software for processing; The main control service board performs protocol conversion, service data processing, and service data statistics on the data, and then sends the data to the specified other port according to the configuration information selected by the user port, and encapsulates the service data and the specified port information into the original MAC frame format and sends it back to the synchronous interface daughter board; After receiving the data returned by the service main board, the synchronous interface daughter board parses the MAC frame data, extracts the port information therein, and then decodes and converts the level of the service data, and then sends the data to the DTE terminal device of the specified port.
