Compared with prior art, the invention has the following advantages that
When security platform is in remoter or bad environments area, can be updated by remote online, it is flat to safety
The logic card MPU and communication board MCU of platform carry out the update of version and configuration file.
Detailed description of the invention
Fig. 1 is the device of the invention structural schematic diagram.
Fig. 2 is online updating software flow pattern of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
Fig. 1 is the device of the invention structural schematic diagram, is the one 2 universal safety platform for multiplying 2oo2.As shown in Figure 1,
(1) it as A machine with B machine is, is all made of logic card and communication board；
(2) MPU1 and MPU2 is logic card, and MCU is communication board, the communication between logic card and communication board by bus come
It completes；
(3) MPU1 and MPU2 operates above identical function software, completes logical operation function.A machine B machine one main one is standby.
(4) identical function software is run on MCU, completes the communication function of platform.
(5) when online updating, upgrade software by network and message is issued into MCU, message is given to MPU by bus by MCU
Processing；Message is issued MCU by bus by MPU, and message is given to upgrading software by network by MCU；
Fig. 2 is online updating flow diagram.
Detailed process is as follows:
0 stage of STEP:
Step 001: upgrading software sends online updating request message to MPU；
Step 002: principal series MPU1 replys online updating request confirmation message to upgrading software, and version letter is carried in the message
Breath and a flag sequence, all and upgrading software interactive internet messages in this online updating process should identify the mark
Will sequence；
1 stage of STEP:
Step 101: upgrading software sends file download command messages to MPU, and principal series MPU1 storage file download command disappears
Number, title and the corresponding version of the file updated in breath；
Step 102: after other MPU receive the file download command messages that upgrading software is sent, being sent in principal series MPU1
Line updates file download order and receives bus message.
Step 103: after principal series MPU1 receives the online updating file download order reception message that every other MPU is sent,
Version updating mode inbound message is sent to every other MPU, and sets the time point of next period version updating mode, is started
Online updating timing (a length of 300s when maximum online updating), goes to step 104.Other MPU receive the entrance of version updating mode and disappear
Breath, also accordingly sets next period as the time point of version updating mode.When MPU starts next period, main task will be hung up.
Step 104: principal series MPU1 replys online updating file download confirmation message and gives upgrading software.
2 stage of STEP:
Step 201: upgrading software sends online updating TFTP to MPU and starts internet message；After MPU receives the message, kill
Dead main task, principal series MPU1 go to step 202；
Step 202: principal series MPU1 sends TFTP transmission to all MCU and starts bus message, and MCU goes to step 203；
Step 203:MCU starts TFTP transformation task, receives file and storage to FLASH from software is upgraded, goes to step
204；
After step 204:MCU has received TFTP file, TFTP transformation task is sent to MPU and completes message；
Step 205: principal series MPU1 is received after first TFTP transformation task complete message, to sending the bus message
MCU replys online updating file distributing and starts bus message；
Step 206:MCU is received after online updating file distributing starts bus message, read from FLASH it is all it is online more
New file goes to step 207 if reading successfully；
Step 207: the MCU send online updating file distributing bus message to other update in need board, and
The board that online updating file distributing is needed to update to other.After being sent completely, if desired MCU itself updates, should be itself
Online updating file be read into memory, and to principal series MPU1 send file reception complete confirmation message.After the completion of above,
MCU should remove all online updating files in FLASH.After the board that other needs update receives online updating file, answer
File reception, which is sent, to principal series MPU1 completes confirmation message；
Step 208: after principal series MPU1 receives the file reception completion confirmation message that all boards to be updated are sent, to upgrading
Software sends TFTP and is transmitted confirmation internet message；
STEP 3:
Step 301: upgrading software sends upgrading to principal series MPU1 and restarts message；
Step 302: principal series MPU1 is received after the upgrading sent of upgrading software restarts message, to upgrading software reply it is online more
Newly restart confirmation message；
Step 303: principal series MPU1 is received after the upgrading sent of upgrading software restarts message, is sent and is risen to other all boards
Grade is completed to restart bus message；
Step 304: the online updating file of itself is covered corresponding ancient deed by principal series MPU1；Each board, which receives, have been upgraded
After restarting bus message, online updating file is covered into corresponding ancient deed；
Step 305: after the completion of each board online updating file covering, restarting；
There are also following features for above-mentioned steps:
1, the communication information upgraded in Fig. 2 between software and MPU does not communicate with each other directly, is all turned by communication board MCU
Hair；
2, online updating timing time-out then enters online updating error handler；
3, online updating error handler is as follows:
Principal series MPU1 sends update failure failure to other all boards and restarts message, and itself restarts.
After other boards, which receive the online updating failure failure that principal series MPU1 is sent, restarts message, Ying Zishen is restarted.MCU
The online updating file in FLASH should be removed before the restart.
