The bridge module receives an FC-AE-1553 control instruction sent by the optical fiber switch, converts the FC-AE-1553 control instruction through an MIL-STD-1553 protocol to generate an MIL-STD-1553 data instruction, and forwards the generated MIL-STD-1553 data instruction to the terminal equipment A through an MIL-STD-1553 bus. The bridge module converts the FC-AE-1553 control instruction into a GJB1188B protocol to generate a GJB1188B data instruction, and forwards the generated GJB1188B data instruction to the terminal equipment B through a GJB1188B bus.
And the terminal equipment A receives an MIL-STD-1553 data instruction sent by the bridge module, generates MIL-STD-1553 feedback data, and sends the generated MIL-STD-1553 feedback data to the bridge module through an MIL-STD-1553 bus. And the terminal device B receives the GJB1188B data instruction sent by the bridge module, generates GJB1188B feedback data, and sends the generated GJB1188B feedback data to the bridge module through a GJB1188B bus.

After receiving the MIL-STD-1553 feedback data replied by the terminal device a, the bridge module temporarily stores the MIL-STD-1553 feedback data replied by the terminal device a and does not send the data to the optical fiber switch.
When the main controller module configures an FC-AE-1553 control instruction according to an FC-AE-1553 protocol, a query instruction corresponding to the control instruction needs to be added and configured immediately, namely a query instruction corresponding to the control instruction is generated additionally and is forwarded to the bridge module through the optical fiber switch; the sending time of the query command of the FC-AE-1553 control command and the sending time interval of the configured FC-AE-1553 control command are more than or equal to the response time of MIL-STD-1553 feedback data.

After the bridge module receives a query instruction of a certain FC-AE-1553 control instruction sent by the main controller module through the optical fiber switch, the bridge module immediately performs FC-AE-1553 protocol conversion on MIL-STD-1553 feedback data replied by the terminal equipment A to form an upper computer feedback instruction and forwards the upper computer feedback instruction to the main controller module through the optical fiber switch; and the upper computer feedback instruction received by the main controller module is sent to the upper computer through the Ethernet.
The invention adopts the following technical scheme.
Modifying the way in which MIL-STD-1553 messages are processed in a bridge module
After the main controller module sends the instruction to the terminal device a, it usually needs to wait for the terminal device a to reply data and status response. After receiving the MIL-STD-1553 feedback data replied by the terminal device a, the bridge module conventionally performs protocol conversion immediately and forwards the data to the main controller module through the optical fiber switch. The key point influencing the transmission efficiency and the throughput of the system is that the main controller module waits for the terminal device A to reply the MIL-STD-1553 feedback data. Therefore, the mode of processing the MIL-STD-1553 message in the bridge module is modified, and after receiving the MIL-STD-1553 feedback data replied by the terminal device A, the bridge module temporarily stores the MIL-STD-1553 feedback data replied by the terminal device A and does not send the feedback data to the optical fiber switch.
The main controller module initiates an instruction of inquiring MIL-STD-1553 feedback data
Estimating the response time of the MIL-STD-1553 feedback data replied by the terminal equipment A, and immediately adding and configuring a query instruction corresponding to an MIL-STD-1553 message when the main controller module configures the MIL-STD-1553 message according to the FC-AE-1553 protocol. The sending time of the message inquiry command and the sending time interval of the message should be greater than or equal to the response time. After the main controller module sends the instruction to the terminal device A, the main controller module does not need to wait for the terminal device A to reply the MIL-STD-1553 feedback data, and continues to process the next MIL-STD-1553 message or GJB1188B message. After the main controller module sends the query instruction of a certain MIL-STD-1553 message, the bridge module immediately performs protocol conversion on MIL-STD-1553 feedback data replied by the terminal equipment A and forwards the data to the main controller module through the optical fiber switch.
After the terminal device a finishes sending the instruction, it is usually necessary to wait for the terminal device a to reply the MIL-STD-1553 feedback data. And after receiving the MIL-STD-1553 feedback data replied by the terminal equipment A, the bridge module temporarily stores the MIL-STD-1553 feedback data replied by the terminal equipment A and does not send the feedback data to the optical fiber switch.
A bridge module: and receiving an FC-AE-1553 control instruction sent by the optical fiber switch, converting the FC-AE-1553 control instruction into an MIL-STD-1553 protocol to generate an MIL-STD-1553 data instruction, and forwarding the generated MIL-STD-1553 data instruction to the terminal equipment A through an MIL-STD-1553 bus. The bridge module converts the FC-AE-1553 control instruction into a GJB1188B data instruction after the GJB1188B protocol is converted, and forwards the generated GJB1188B data instruction to the terminal equipment B through a GJB1188B bus; receiving MIL-STD-1553 feedback data sent by terminal equipment A and GJB1188B feedback data sent by terminal equipment B, storing the MIL-STD-1553 feedback data, converting the GJB1188B feedback data through an FC-AE-1553 protocol to generate FC-AE-1553 feedback data, and sending the generated FC-AE-1553 feedback data to an optical fiber switch through an FC-AE-1553 bus.
After receiving a query instruction of a certain MIL-STD-1553 message sent by the main controller module, the bridge module immediately performs protocol conversion on MIL-STD-1553 feedback data replied by the terminal device A and forwards the data to the main controller module through the optical fiber switch.
After receiving the instruction of the upper computer, the main controller module sends the message according to the following steps:
and calculating the response time delta T of the feedback data of the MIL-STD-1553 replied by the terminal equipment A in the MIL-STD-1553 protocol. Taking 64 bytes as an example, the transmission time of 1 word (16 bits) is 20 μ s, the transmission of 64 bytes of data requires 1 command word plus 1 status word plus 32 data words, plus the message response time, and the response time Δ T of MIL-STD-1553 feedback data is about 800 μ s at maximum.
And the main controller module stores the received upper computer control instruction (including an MIL-STD-1553 message and a GJB1188B message) in a message queue.
The main controller module takes out a message from the message queue, analyzes and processes the RT address, the RT sub-address, the data length, the data content and the message type in the message, and divides the message into two types of NC- > NT type and NT- > NC type.
The main controller module configures the message type, the source ID of message sending, the destination ID of message sending, the source address of message sending, the destination address of message sending, the message length, the message content and the message interval time of each message according to the FC-AE-1553 protocol. When the message type is an MIL-STD-1553 message, the main controller module needs to immediately increase and configure a query instruction corresponding to the message when configuring an MIL-STD-1553 message according to an FC-AE-1553 protocol. The sending time of the message inquiry command and the sending time interval of the message should be greater than or equal to the response time delta T. When the message type is a GJB1188B message, the main controller module does not need to configure the query instruction of the message.
The main controller module stores each configured message (including the query instruction) in the same message stack, and the main controller module sequentially executes the sending operation of each message according to the arrival time sequence of the messages in the message stack. If an MIL-STD-1553 message is stored in the message stack firstly and then a GJB1188B message is stored, after the MIL-STD-1553 message is sent, the GJB1188B message is continuously sent without waiting for the reply information of the message.
The main controller module judges the value of the interrupt state register of the module, and if the interrupt state register shows that all frames in the current message stack are processed, the main controller module indicates that all frames in the current message stack are sent completely. At this time, the main controller module takes out the control instruction message sent by the next upper computer from the message queue, and executes the analysis processing of the subsequent messages.
According to the invention, by modifying the mode of processing the MIL-STD-1553 message in the bridge module and initiating the command of inquiring the data and state replied by the MIL-STD-1553 by the main controller module, the main controller module can respond and process the command sent by the upper computer in time when MIL-STD-1553 bus data and GJB1188B bus data are transmitted in a mixed manner, and the transmission efficiency and the throughput of the system are improved.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make variations and modifications of the present invention without departing from the spirit and scope of the present invention by using the methods and technical contents disclosed above.
