Abstract
A military standard-1760 (MIL-STD-1760) interface bridge can include a housing, a translator device, and an energy storage device. The housing can include a MIL-STD-1760 connector on a first end and a weapon side connector on a second end. The translator device can translate a MIL-STD-1553B remote terminal (RT) protocol to a weapon side signaling protocol and translate the weapon side signaling protocol to the MIL-STD-1553B RT protocol. The energy storage device can be coupled to the operating power of the MIL-STD-1760 connector and can be configured to provide power to the translator device for a duration after the power from the MIL-STD-1760 connector is disconnected.
Claims22
A military standard-1760 (MIL-STD-1760) interface bridge comprising:
- a housing including a MIL-STD-1760 connector on a first end and a weapon side connector on a second end;
- a translator device to translate a MIL-STD-1553 remote terminal (RT) protocol to a weapon side signaling protocol and translate the weapon side signaling protocol to the MIL-STD-1553 RT protocol;
- and
- an energy storage device coupled to the operating power of the MIL-STD-1760 connector and configured to provide power to the translator device for a duration after the power from the MIL-STD-1760 connector is disconnected.
A method for communicating from a military standard-1760 (MIL-STD-1760) remote terminal (RT) to an enhanced bit rate-1553 (EBR-1553) bus controller (BC), comprising:
- receiving a receive message (‘R’ message) at the MIL-STD-1760 RT via a MIL-STD-1760 interface;
- buffering data contents of the ‘R’ message in memory;
- generating, by the MIL-STD-1760 RT, an interrupt for a processor indicating the ‘R’ message;
- scheduling the transmission of the ‘R’ message by the EBR-1553 BC via command by the processor;
- and
- transmitting the ‘R’ message by the EBR-1553 BC to a weapon interface when a transmit message (‘T’ message) is not being received.
An enhanced bit rate-1553 (EBR-1553) bus controller (BC) for communicating with a weapon EBR-1553 remote terminal (RT) having computer circuitry configured to:
- poll for a transmit message (‘T’ message) by the EBR-1553 BC via a weapon interface;
- compare, by a processor, the ‘T’ message with data contents of a corresponding ‘T’ message buffer, wherein the corresponding ‘T’ message buffer is configured to be accessed by the EBR-1553 BC and the MIL-STD-1760 RT;
- and
- update the corresponding ‘T’ message buffer with data contents of the ‘T’ message when the ‘T’ message differs from the data contents of the corresponding ‘T’ message buffer.
