Embodiment Construction

[0030] The internal structure of the remote intelligent interface unit is as follows: figure 1 As shown, it implements the cockpit man-machine interface and its keyboard operation processing, collects discrete quantities and I / O interface data output by HOCAS, AAP and other equipment, and processes them. Signal types include RS422 interface, ARINC429 interface, and 27V / ground, 27V pulse, 27V / open circuit, ground / open discrete signal. After the collected signal is preprocessed, it is transmitted to the core processor through the AFDX network for comprehensive processing, and the core processing control output signal is transmitted to the remote intelligent interface unit through the AFDX network for control and drive output.

[0031] The remote intelligent interface software control method is described as follows:

[0032] Initial task: This task mainly completes the following tasks:

[0033] (1) According to the initial setting of the application configuration table, the ini...

Abstract

The invention provides a remote intelligent interface unit and a control method. The problems that transmission of an existing sensor interface is in mutual interference, and signals of the sensor interface and signals of an effector interface are in mutual interference are mainly solved. The remote intelligent interface unit comprises an Avionics Full Duplex Switched Ethernet (AFDX) network interface which is connected with an integrated core processor, and the AFDX network interface is connected with an internal bus through a dual-port random access memory (DPRAM). The remote intelligent interface unit further comprises a storer, a control logic device, a power inverter and an external interface which are respectively connected with the internal bus. The storer is connected with the internal bus through a PPC 8245. The remote intelligent interface unit can achieve nearby collection, timely converting and distribution control of interface data, and enable a system to be expanded and updated conveniently.

Description

technical field [0001] The technical field belongs to embedded computer system design technology. Background technique [0002] As the complexity of various interfaces of airborne embedded systems continues to increase, the transmission distance of interface signals increases, and the application environment becomes more and more harsh, the problem of mutual interference between sensor interface transmission and the relationship between sensor interface signals and effector interface signals appears. These problems seriously affect the quality of signal acquisition, and then affect the security of the system. Contents of the invention [0003] The invention provides a remote intelligent interface unit and a control method, which mainly solve the problems of mutual interference in transmission of existing sensor interfaces and mutual interference between sensor interface signals and effector interface signals. [0004] The concrete technical solutions provided by the prese...
