Embodiment Construction

[0025] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] This embodiment proposes a 100M 1553B transmission and control bus terminal board, which is inserted into the chassis of the transmission and control equipment to realize the transmission and reception control of four 100M buses. The principle of the bus termination board is as follows figure 1 As shown, it mainly includes CPCI backplane connector, processor DSP6455, Stratix Ⅳ FPGA, analog front end and connector.

[0027] Among them, the CPCI backplane connector is used to transmit PCI signals to realize the communication between the 100M 1553B transmission control bus terminal board and the transmission control equipment main board. The main board of the transmission and control equipment transmits the data so...

Abstract

The invention belongs to the technical field of bus control, and particularly relates to a terminal board card of a 1553B launch and control bus of hundreds of megabytes. The terminal board card comprises a CPCI base board connector, a processor, an FPGA, a simulation front end and a connector; the effect of the bus of hundreds of megabytes is mainly achieved by adopting high-speed AD and DA technologies and a simulation front end technology; and the board card communicates with a launch and control equipment main board through the bridge piece function of the processor, control over an ADC and a DCA is achieved through the FPGA on the board card, signals of the DAC pass through a differential-to-single end device and a smoothing filter and then are output to an analog switch, the analog switch switches output of the DAC and input of the ADC, input signals of the ADC pass through an anti-alias filter and a single end-to-differential device and then are input into the ADC. According tothe terminal board card, real-time performance requirements of full missile rapid response can be met, and the speed of the launch and control bus is increased.

Description

technical field [0001] The invention belongs to the technical field of bus control, and in particular relates to a 100M 1553B transmission control bus terminal board. Background technique [0002] The launch control bus is an indispensable part of the weapon system. With the development of new bus technology, the continuous improvement of measurement launch control technology and the development of missile technology, higher requirements are put forward for the transmission bandwidth of the launch control bus. [0003] At present, the 1M 1553B bus is used for image binding on the airborne, ship-borne, and vehicle-mounted launch control buses. The transmission of large data files takes too long to meet the real-time requirements of the rapid response of the whole bomb. It is imminent to increase the speed of the launch control bus. Contents of the invention [0004] (1) Technical problems to be solved [0005] The invention proposes a 100M 1553B transmission control bus te...
