Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The general intelligent remote data concentrator shown in this embodiment has the following two functions: gateway function, calculation and fast loopback function. The gateway function is mainly used for data forwarding and links between networks, see figure 1 shown. Computing and fast loopback are mainly used in environments that require fast response or controller functions, and perform calculations directly on the RDC, and perform loopback processing at the remote end, see figure 2 shown.

[0025] For gateway functionality, see image 3 As shown, the general intelligent remote data concentrator includes four software modules: a configuration table parsing module, a data receiving module, a data forwarding module and a data sending module.

[0026] see Figure 4 As shown, the configuration table parsing module is executed after...

Abstract

The invention discloses a general intelligent remote data concentrator, which comprises the following software modules: the configuration table analysis module obtains the installation position of the general intelligent remote data concentrator by reading the discrete quantity of the position, and reads the configuration table according to the installation position to obtain the current position Configuration information, convert the configuration information into an internal data structure, and finally fill it into the structure of the data receiving module, data forwarding module and data sending module; the data receiving module periodically reads the bus data cached in the receiving buffer area, and transfers the bus The data is decomposed into data sets and stored in the forwarding buffer area; the data forwarding module reads the data sets in the forwarding buffer area in turn, and puts the data sets into the sending buffer area specified by the sending message according to the configuration; the data sending module follows the configuration cycle Read the data in the sending buffer and send it. The invention can realize efficient, reliable, universal and configurable forwarding.

Description

technical field [0001] The invention relates to the field of aviation system embedded software design, in particular to remote data interface products. Background technique [0002] Remote Data Concentrator (RDC), first proposed by Boeing, is currently widely used in civil aircraft, transport aircraft and other avionics systems. Both A380 and B737 use this technology. In the context of the highly integrated aircraft avionics system (IMA architecture), the remote data interface unit is an important data node all over the aircraft. More and more aircraft use the remote data interface unit, which replaces the traditional dedicated signal It facilitates the separation of components, minimizes the wiring and weight of subsystems, sensors, and effectors, and is easy to update the system. It is of great significance to the reliability, maintainability, and versatility of aviation systems. [0003] my country's self-designed civil aircraft C919 uses a large number of remote data in...
