Benefits of technology

The technical effect described in this patented patents is an improvement over current systems used for managing airplanes' communication networks (CAN) due to their high reliance on hardwarp programming techniques such as MSI-512/MIL-32 serial interfaces. These improvements include faster processing speed, less memory usage, easier integration between different components within the network, enhanced functionality capabilities, simplified deployment processes, etc., making these technologies more practical than older designs. Overall, they improve performance and ease of implementation across various types of applications.

Problems solved by technology

This patented describes various limitations associated with current 1553 B bus monitoring devices that require external input or data manipulation (PCI) connections between components inside the device itself. These limitations include difficulty accessing relevant diagnoses due to long training hours required, low efficiency when analyzing signals at multiple levels within one component, and difficulties updating firmware without specialized tools such as vibrating sensors. Additionally, there may exist issues related to upgraded products made available through foreign companies who want them better than traditional ones.

Embodiment 1

[0047] Example 1, see figure 1 , 3 , 4, 5, 6, 7, 8, the present invention adopts: hardware design→firmware program design→driver program design→general monitoring application program design→ICD special document analysis tool design steps, design from bottom to top. Instructions are given below in order of design.

[0048] 1. Hardware design:

[0049] The hardware design is mainly to complete the USB-1553B protocol converter design. The protocol converter is formed by superimposing the USB module and the 1553B module, and the USB-1553B protocol converter 2 is formed by superimposing the USB module and the 1553B module; there is a 68013 embedded processor on the USB module, and the 68013 embedded processor and memory EEPROM, Connect the voltage conversion circuit, crystal oscillator, and test signal pins, first connect to the pins through a custom bus, and then connect to the HT-61580 embedded processor; connect to the control computer 4 through the USB bus connector; HT-6158...

Embodiment 2

[0098] Example 2, see figure 2 , the same as embodiment 1, the difference is that the control computer 4 is connected to the data storage terminal 6 and the printer 7 through the Ethernet 5, the printer 7 interacts with the user 8, and finally connects the 1553B bus 1 to the device under test 9, this connection method Good for infield work.

[0099] The portable aircraft 1553B bus monitoring system based on the USB interface of the present invention, after the system starts running, collects the 1553B bus signal through the 1553B module, and the signal is transmitted to the control computer after protocol conversion in the USB module, and the control computer can call the general 1553B bus on the one hand The monitoring module displays and analyzes the 1553B original signal by comparing the signals and verifying the status word. On the other hand, it can call the ICD file analysis module to compare the contents of the aircraft’s ICD file database with the received signals. A...

Abstract

The invention discloses a portable airplane 1553B bus monitoring system based on a universal serial bus (USB) interface. The portable airplane 1553B bus monitoring system comprises a 1553B bus (1) and is characterized in that: the 1553B bus (1) is connected with a USB-1553B protocol converter (2); and the USB-1553B protocol converter (2) is connected with a control computer (4) through a USB (3) so as to control interaction between the computer (4) and a user. The USB interface is connected with the portable control computer, so that the volume is small, the portability is high, and the system is applicable to two working environments, namely an outer field working environment and an inner field working environment; furthermore, a USB module and a 1553B module in the protocol converter can be stacked with other bus modules respectively so as to form a novel bus protocol converter; therefore, the cost is reduced and the uniformity, the modulation and the speciality of the system are improved.
