[0023] This invention discloses an adaptive multi-network conversion device that is simple to implement, highly reliable, and has good availability. See [link to relevant documentation]. Figure 1 As shown, the device includes a network protocol conversion module, a monitoring module, and multiple different types of network transceiver modules. The network transceiver module is equipped with a data receiving channel, a data sending channel, and a loopback network. The data receiving channel receives the raw data collected by the external network, the data sending channel outputs the new data after network conversion to the external network, and the loopback network is used for testing.

[0024] The network protocol conversion module is equipped with multiple network conversion protocols. It performs network protocol conversion on the received raw data to obtain the new data through different network conversion protocols. The monitoring module is interconnected with the network protocol conversion module and the network transceiver module. The monitoring module includes a monitoring module and a testing module. The monitoring module performs network monitoring on the network protocol conversion module and the network transceiver module, and the testing module performs loopback testing on the network protocol conversion module and the network transceiver module.

[0025] Furthermore, the network transceiver module includes a 1394B network transceiver module, a TTE network transceiver module, and an FC network transceiver module.

[0026] Furthermore, the external networks connected to the TTE network transceiver module and the FC network transceiver module include optical networks, and the external networks connected to the 1394B network transceiver module include both optical and electrical networks.

[0027] Furthermore, the monitoring module performs network monitoring based on its own status information output by the network protocol conversion module and the network transceiver module. Even further, the own status information includes operating status, network switching status, and data transmission / reception status.

[0028] Specifically, the aforementioned 1394B network transceiver module M1 is used to receive 1394B data (i.e., raw data) from 1394B electrical and optical networks in real time, transmit the 1394B data to the network protocol conversion module M4 through a high-speed network interface, and periodically transmit its own status information, including whether it is working properly, whether the network conversion is successful, and whether data transmission and reception are normal, to the monitoring module M5. When necessary, it can obtain instructions from the monitoring module M5 (such as inspection instructions and network conversion instructions) to dynamically configure its own working status and network speed. The 1394B network transceiver module M1 also has a direct connection interface with the TTE network transceiver module M2 and the FC network transceiver module M3 through the network protocol conversion module M4 to complete internal loopback transmission, thereby realizing the loopback monitoring function of the system. In addition, the 1394B network transceiver module M1 also has two external physical connection modes: 1394B optical network and electrical network, supporting interconnection with external 1394B optical network or 1394B electrical network devices.

[0029] The aforementioned TTE network transceiver module M2 is used to receive TTE network data signals from the TTE network in real time, transmit the TTE data to the network protocol conversion module M4 through a high-speed network interface, and periodically transmit its own status information to the monitoring module M5. When necessary, it can obtain instructions from the monitoring module M5 to dynamically configure its own working status and network speed. The TTE network transceiver module M2 also has a direct connection interface with the 1394B network transceiver module M1 and the FC network transceiver module M3 through the network protocol conversion module M4 to complete internal loopback transmission and thus realize loopback monitoring function.

[0030] The aforementioned FC network transceiver module M3 is used to receive FC network data signals from the FC network in real time, transmit the FC data to the network protocol conversion module M4 through a high-speed network interface, and periodically transmit its own status information to the monitoring module M5. When necessary, it can receive instructions from the monitoring module M5 to dynamically configure its working status and network speed. The FC network transceiver module M3 also has a direct connection interface with the 1394B network transceiver module M1 and the TTE network transceiver module M2 through the network protocol conversion module M4, used to complete internal loopback transmission and thus realize loopback monitoring functionality.

[0031] Furthermore, the network protocol conversion module includes an FPGA programming logic module. The FPGA programming logic module constructs network conversion protocols between different networks based on the network configuration information output by the monitoring module, and parses the received raw data and loopback test data.

[0032] Specifically, the network protocol conversion module M4 can construct and parse data for 1394B, FC, and TTE networks, and forward data to the target network. It enables the parsing and distribution of different network data between 1394B networks (including IEEE 1394B / Milli 1394B) and FC networks, 1394B networks and TTE networks, and FC networks and TTE networks. Simultaneously, the network protocol conversion module M4 periodically transmits its own status information to the monitoring module M5. When necessary, it can receive instructions from the monitoring module M5 to dynamically configure its working status and network mode selection. The protocol conversion module M4 also has direct connection interfaces with the 1394B network transceiver module M1, the TTE network transceiver module M2, and the FC network transceiver module M3 to complete internal loopback transmission, thereby realizing loopback monitoring functionality.

[0033] Furthermore, the monitoring module includes a configuration module, which configures the network rate and operating mode of the network transceiver module and the network protocol conversion module.

[0034] Specifically, the monitoring module M5 is interconnected with the 1394B network transceiver module M1, the TTE network transceiver module M2, the FC network transceiver module M3, and the network protocol conversion module M4 via an internal network. It receives status information, real-time monitoring information, and other data from these modules and transmits it to external devices connected to the device via the interconnected network. Simultaneously, it acquires configuration or other commands from external devices and transmits these commands to the four interconnected modules as needed, completing the dynamic configuration of the modules. If necessary, the four interconnected modules can also be organized to perform an internal loopback test to verify whether the conversion device is functioning correctly.

[0035] This invention also provides an adaptive multi-network conversion method, which uses the adaptive multi-network conversion device provided in the above embodiments to achieve conversion between different types of networks and device self-testing. The method includes:

[0036] S1. Parse the instructions output by the host computer to obtain network configuration information, and construct a network protocol conversion protocol based on the network configuration information.

[0037] The network protocol conversion protocol can be configured to operate in independent (one-to-one) or simultaneous (one-to-many or many-to-many) modes, and supports real-time monitoring and dynamic configuration of the conversion process. Specifically, the monitoring module M5 parses the instructions (data conversion instructions, communication instructions, etc.) output by the host computer and configures the interaction between various network modules according to the parsed instructions (such as configuring identity information as receiver, sender, or idle, configuring source address, destination address, network protocol, etc.) to configure the conversion module.

[0038] S2. The original data received from one type of network is converted using the network protocol conversion protocol to obtain new data, and the new data is output through another type of network data.

[0039] When performing network conversion, such as Figure 2 , Figure 3 and Figure 4 As shown, Figure 2This system is used to implement the automatic conversion process between IEEE 1394B / Mil 1394B networks and TTE networks. The functional modules involved include a 1394B network transceiver module M1, a TTE network transceiver module M2, a network protocol conversion module M4, and a monitoring module M5. The 1394B network transceiver module M1 collects and preprocesses 1394B electrical or optical network data (analyzing and removing abnormal data), then transmits the data to the network protocol conversion module M4. The network protocol conversion module M4 parses the 1394B network data and performs network protocol conversion, converting the data to TTE network data format. Simultaneously, the converted TTE network data is sent to external devices through the transmission interface of the TTE network transceiver module M2. During the above conversion process, the operating status of the 1394B network transceiver module M1, the TTE network transceiver module M2, and the network protocol conversion module M4 are all monitored by the monitoring module M5. The monitoring module M5 sends the collected status information of the 1394B network transceiver module M1, the TTE network transceiver module M2, and the network protocol conversion module M4 to external devices through the external communication network of the monitoring module M5. At the same time, the monitoring module M5 receives relevant commands from external devices in real time, parses and processes the commands, and sends them to the 1394B network transceiver module M1, the TTE network transceiver module M2, and the network protocol conversion module M4 respectively.

[0040] Figure 3 The automatic conversion process between IEEE 1394B / Mil 1394B and FC networks involves functional modules including the 1394B network transceiver module M1, the FC network transceiver module M3, the network protocol conversion module M4, and the monitoring module M5. The 1394B network transceiver module M1 collects and preprocesses the 1394B electrical or optical network data before transmitting it to the network protocol conversion module M4. The network protocol conversion module M4 parses the 1394B network data and performs network protocol conversion, converting the data to FC network format. Simultaneously, it sends the converted FC network data to external devices through the transmission interface of module M3. During the above conversion process, the operating status of the 1394B network transceiver module M1, the FC network transceiver module M3, and the network protocol conversion module M4 are all monitored by the monitoring module M5. The monitoring module M5 sends the collected status information of the 1394B network transceiver module M1, the FC network transceiver module M3, and the network protocol conversion module M4 to external devices through the external communication network of the monitoring module M5. At the same time, the monitoring module M5 receives relevant commands from external devices in real time, parses and processes the commands, and sends them to the 1394B network transceiver module M1, the FC network transceiver module M3, and the network protocol conversion module M4 respectively.

[0041] Figure 4The automatic conversion process between TTE and FC networks involves functional modules including TTE network transceiver module M2, FC network transceiver module M3, network protocol conversion module M4, and monitoring module M5. TTE network transceiver module M2 collects and preprocesses TTE network data before transmitting it to network protocol conversion module M4. Network protocol conversion module M4 parses and performs network protocol conversion on the TTE network data, converting it to FC network format. Simultaneously, it sends the converted FC network data to external devices via the built-in sending interface of FC network transceiver module M3. During the above conversion process, the operating status of TTE network transceiver module M2, FC network transceiver module M3, and network protocol conversion module M4 are all monitored by monitoring module M5. The collected status information of TTE network transceiver module M2, FC network transceiver module M3, and network protocol conversion module M4 is sent to external devices through the external communication network of M5. At the same time, relevant commands sent by external devices are received in real time, and after parsing and processing the commands, they are sent to TTE network transceiver module M2, FC network transceiver module M3, and network protocol conversion module M4 respectively.

[0042] S3. Generate loopback test data and perform loopback tests on each module of the adaptive multi-network conversion device through the loopback network.

[0043] In practice, the loopback test is performed through all modules within the device. The specific process is as follows: Monitoring module M5 sends loopback test data ④ to 1394B network transceiver module M1. 1394B network transceiver module M1 generates data ① through the loopback network and sends data ① to network protocol conversion module M4. Network protocol conversion module M4 converts data ① into data ② according to the above step (2) and sends it to TTE network transceiver module M2. After receiving data ②, TTE network transceiver module M2 sends data ② to network protocol conversion module M4 through its internal loopback network. Network protocol conversion module M4 converts data ② into data ③ according to the above step (3) and sends it to FC network transceiver module M3. After receiving data ③, FC network transceiver module M3 converts data ③ into test data ⑤ through its internal loopback network and sends it to monitoring module M5. After receiving test data ⑤, monitoring module M5 compares it with the sent test data ① to determine the IEEE 1394B / Mi of all modules. Is the automatic switching between the L1394B network and the TTE network, and between the TTE network and the FC network, normal? It should be noted that the path of the test data within the device can be designed according to user needs. For example, the loopback test data output by the monitoring module M5 can also be sent first to the TTE network transceiver module M2, the FC network transceiver module M3, or the network protocol conversion module M4.

[0044] The adaptive multi-network conversion device and implementation method of the present invention can receive multi-type network data sent by external devices in real time and independently, and automatically perform conversion processing through internal conversion structure. The process is transparent, and the conversion status and network data timeliness are monitored in real time. It can also be dynamically configured according to external device commands. It has the characteristics of fast data reception and conversion, high data transmission efficiency, and strong reliability and real-time performance.
