Embodiment 1

[0032] A fault data recording method based on avionics equipment, comprising the steps of:

[0033] Step 1: The control device sends the working mode and start-up time to processor A through the communication string;

[0034] Step 2: Processor A generates data recording control instructions according to the working mode, and sends the boot time to logical processor B;

[0035] Step 3: Logic processor B starts logic control to process serial port data and discrete data, save sampling data and send an interrupt to processor A;

[0036] Step 4: Processor A receives the interrupt and reads the sampling data through the bus, and saves the sampling data to the memory to complete the data recording.

Embodiment 2

[0038] Methods also include:

[0039] Step 5: Skip to step 2. Processor A generates a data communication control instruction according to the working mode to enter the data communication mode;

[0040] Step 6: Processor A is connected to the data collection device through the Ethernet interface to complete data output.

Embodiment 3

[0042] A fault data recording device based on avionics equipment, including a control device, a logic processor B, a processor A, a communication serial port, a memory, a bus and a power supply, the control device is connected to the processor A through the communication serial port, and the processor A is connected through the bus It is connected with logical processor B, and the memory is connected with processor A to complete data recording. By setting integrated logic processor B, processor A, control equipment and general peripheral circuits, hardware software is realized, the number of devices is reduced, and the size of the device is reduced. Combined with memory, bus and communication serial port, real-time recording of operating data is realized. .

Abstract

The invention discloses a fault data recording method and apparatus based on avionics devices, and relates to the technical field of avionics devices. The method includes the following steps: 1. a control device transmitting a work mode and a power-on time to a processor A through a communication string; 2. the processor A generating a data recording control command based on the work mode and transmitting the power-on time to a logic processor B; 3. the logic processor B starting logic control, processing serial port data and discrete data and saving sample data and transmitting an interruption to the processor A; and 4. the processor A receiving the interruption and reading the sample data through a bus, and saving the sample data to a storage device for recording the data. Current faultdata recording apparatuses often use computer system platforms which are too large in sizes, and often use systems which fail to independently and temporarily establish simple platforms. As a result,data recording is difficult and universality lever is low. The method and the apparatus greatly reduce the size and weight of an apparatus and can real-timely record data.

Description

technical field [0001] The invention relates to the field of avionics equipment, in particular to a fault data recording method and device based on avionics equipment. Background technique [0002] With the development of science and technology, avionics equipment is gradually integrated. When the equipment fails, especially when there is a failure that is difficult to reproduce or expensive to reproduce, it is necessary to save the original data to reduce the difficulty of locating the fault point and finding the fault, thereby shortening the time. Research and development, commissioning, production and maintenance cycles greatly improve the attendance rate of products. [0003] In the current domestic and foreign markets, in order to timely and accurately locate the equipment failures in the process of development, production and debugging, the original signal recording of the equipment is usually carried out by means of special recording equipment and a simple platform te...
