And a variety of load modes such as unified loading.
Invention content
The purpose of the present invention：The present invention proposes a kind of IMA system datas loading framework and loading method, in order to improve
IMA data load data, improve system maintenance, and the loading of IMA system datas is supported by Ethernet interface general all the way
Newer method.The data loading support platform in all data loading, including the upper application software to be updated of CPU, DSP,
Logical code and allocation list, driving etc. support a variety of load modes such as list CPU loadings, multi -CPU loading and unified loading.This
Sample causes entire task system upgrade logic, software to be foreshortened to 0.5 hour by two days.Upgrading no longer needs additionally to install special soft
Part and carrying specific purpose tool, outfield directly can originally complete to upgrade with common notes.It can carry out condition managing and Version Control.
Technical scheme of the present invention：
The present invention proposes that the present invention proposes a kind of IMA system datas loading framework and loading method is realized to IMA systems
The loading function of the data such as application software, logical code and the allocation list of various functions module, driving.
As shown in Figure 1, IMA system datas loading framework includes host side and target generator terminal, the two is assisted by Ethernet UDP
View communicates.
Host side include loading interface, loading interface program, single module loading, multimode loading, electric board loading,
Load communication protocol interface.Interface is loaded for setting loading data type, loading type.Loading interface program will load
Data type is packaged.Single module loading, which is realized, loads the data of individual feature module.Multimode loading is realized to multiple
The data of function module load simultaneously.The loading of large capacity electric board data is realized in electric board loading.Loading communication protocol interface will
Loading data envelope dresses up udp data packet, and call Ethernet into row data communication.
Target generator terminal include several LRM function modules, as MMM modules, IOM modules, DPM modules, NSM modules and other
Module, each module are resident target machine loading Agent, which realizes that loading data unpack and data information cures.
As shown in Fig. 2, IMA system datas loading flow has the following steps：
The first step：Host side loading procedure start-up loading operates, and sends operation requests packet to target hardware, data loading journey
Sequence time-out time is 5 seconds；After target hardware receives operation requests packet, then accept or reject operation to data upload program reply and answer
Answer packet；Target hardware such as receives operation requests, and a status information packet is sent to data upload program；
Second step：Data upload program udp protocol sends header file to target hardware, and UDP time-out times are 5 seconds；
Third walks：After target hardware receives header file, resolution file content extracts the letters such as filename, the verification of loading
Breath；
4th step：Target hardware udp protocol asks transmission file to data upload program, and UDP time-out times are 5 seconds；
5th step：Target hardware is verified and is handled after receiving file, is checked whether file is correct, is needed when file stores
Run time is stayed to status information transmission, in case target hardware cannot send out status information packet and data upload program is caused to surpass on time
When；
6th step：After the completion of target hardware handles All Files, shape is reported to data upload program with status information packet
State information, end operation；
7th step：After data upload program has sent All Files, wait for target hardware status information packet return into
Work(or failure information receive rear end operation；
8th step：In the transmission stage, to data upload program period transmission status information packet, report is current to be added target hardware
Load state.If target hardware finds mistake, the conditional code in status information packet is set according to type of error, is sent to data loading
Program after the response for receiving data upload program, stops file reception and processing, end operation, data upload program is replied should
After response bag, end operation.
It is an advantage of the invention that：
1st, entire task system upgrade logic, software were foreshortened to 0.5 hour by two days
2nd, upgrading no longer needs additionally to install special-purpose software and carries specific purpose tool, and outfield directly originally may be used with common notes
Complete upgrading
3rd, condition managing and Version Control can be carried out
Description of the drawings
Fig. 1 is IMA system datas loading framework
Fig. 2 is IMA system datas loading flow
Specific embodiment：
A kind of IMA system datas loading framework and loading method embodiment are as follows：
