Embodiment 1

[0046] combined with figure 1 , the embodiment of the present invention provides an ARINC659 time planning table program loading device, including: a storage unit 0, a loading LRM unit 1, a plurality of common LRM units 2, an ARINC659 bus 3, and an IEEE 1149.5 bus 4;

[0047] Described storage unit 0 adopts the U-disk mode in the specific implementation, and there are table folder and log folder under the U-disk root directory, wherein the table folder contains table program binary files and configuration files, and the chassis contained in the file name is passed Multiple LRM unit pairs are distinguished by the slot number, and the log folder contains the loading results;

[0048] The loading LRM unit 1, as a USB controller, accesses the storage unit 0 through the USB2.0 bus interface, loads the table program binary file in the table folder to each ordinary LRM unit 2, and receives the readback of the ordinary LRM unit 2 The data is verified, and the loading result is stored...

Embodiment 2

[0054] combined with figure 2 , the embodiment of the present invention also provides a method for loading an ARINC659 time planning table program, including:

[0055] Load the LRM unit to query the binary file and configuration file content of the table program in the storage unit, send a load command, and establish a data transmission connection;

[0056] Send table program data to the designated LRM unit. After the data transmission is completed, the designated LRM unit performs loading processing, and at the same time gives the impact of loading completion.

[0057] The loading LRM unit starts to receive the readback table program data, compares it with the data to be loaded, and uploads the execution structure to the storage unit.

[0058] specific,

[0059] Step 1. When it is necessary to load each LRM unit 2 and 3 with the time planning table program, insert storage unit 0 into the loading LRM unit 1, and after the storage unit 0 is correctly identified, it will be d...

Embodiment 3

[0071] combined with image 3 And attached Figure 4 , a scenario of using the device and method is as follows:

[0072] (1) For the computer system based on the ARINC659 bus, the maintenance personnel are required to be able to load and upgrade the schedule table program for the main control processor board, CAN bus interface board, and ETH bus interface board with multiple redundancy inside the cabinet at the equipment site, And be able to read back the results of maintenance upgrades.

[0073] (2) Use the time planning table program loading method based on the ARINC659 bus, and use the ETH bus interface board in slot 6 in the cabinet as a dedicated loading LRM unit. The ETH bus interface board has a USB 2.0 bus interface, and you can also use WiFi, Zigbee, LTE and other wireless transmission interfaces are upgraded.

[0074] (3) The above ETH bus interface board and the storage unit are connected through the USB bus, and a four-redundancy processor board time planning ta...

Description

technical field [0001] The present invention relates to but not limited to the field of ARINC659 bus technology, in particular to an ARINC659 time planning table program loading device and method. Background technique [0002] ARINC659 bus is a standard for data transmission between various functional modules in a comprehensive modular avionics rack proposed by HoneyWell. The bus adopts the communication mechanism of Table-Driven Proportional Access (TDPA). The bus operation is carried out according to the time schedule scheduled in the design stage, and it is stipulated that the BIU module of the sending node can only transmit the data to the target node when it sends the same data in the same period. , as the internal backplane bus of the chassis in safety-critical fields such as aviation, aerospace, and high-speed rail, once the time schedule of each component inside the chassis is inconsistent, it will not be able to provide reliable inter-node communication. [0003] T...
