Deng.
Step 2: CPU module summarizes the working condition of two I/O module boards and itself board, and by the work after summarizing
Status information is sent to communication module.
Step 3: communication module summarizes work state information that CPU module is sent and itself board working condition, and on
Pass to maintenance terminal.
Step 4: maintenance terminal Microprocessor System for Real Time Record operating status, completes the monitoring to platform.
System running state information can be checked by local log-on or Telnet mode.
Step 5: when being safeguarded to platform, maintenance terminal is downloaded to program bag to be updated using TFTP modes
Communication module.
Step 6: communication module parses the program bag received, and determine whether the more new procedures of communication module, if
It is to enter step seven；Otherwise, eight are entered step；
Step 7: communication module runs program more new command, program bag is cured on the memory of communication module, is laid equal stress on
New activation system realizes the update of program.
Step 8: judge whether the program bag is the more new procedures of CPU module, if so, nine are entered step, otherwise, into
Enter step 10；
Step 9: program to be updated is sent to CPU module by communication module, CPU module runs program more new command, by journey
Sequence packet is cured on the memory of CPU module, and restarting systems realize the update of program.
Step 10: program to be updated is sent to corresponding I/O module by CPU module, I/O module, which is parsed and updated, to be referred to
It enables, by program Solidification to be updated on corresponding memory, and restarting systems realize the update of program.
The advantage of the invention is that：In the case of without using Special programming and not dismantling platform, it is whole to pass through system maintenance
End to all functional modules in platform into line program upgrade and attended operation, effectively raise system installation, debugging, upgrading and
The efficiency of maintenance, shortens maintenance time.Meanwhile maintenance terminal is alternatively arranged as system monitoring equipment, Microprocessor System for Real Time Record operation
State maintains easily personnel and consults historical data.
Description of the drawings
Fig. 1 is that the present invention is monitored platform and safeguards the system block diagram used.
Fig. 2 is a kind of method flow diagram for being monitored and safeguarding to platform of the present invention.
Specific implementation mode
Below in conjunction with drawings and examples, the present invention is described in further detail.
The present invention has software and hardware reality by oneself without using Special programming and under conditions of do not dismantle platform hardware using platform
The status monitoring of each function module of existing system and the automatic upgrading and maintenance of program.
The method is as shown in Fig. 2, be as follows：
Step 1: for the modules of computer, in each cycle of operation T, CPU module receives the board of I/O module
Work state information；
It is T that the present invention, which arranges the one time cycle of operation of platform program, and all boards are followed according to cycle of operation T in platform
Ring executes respective program.
The modules of the computer, as shown in Figure 1, including：Maintenance terminal, communication module, CPU module and two
A I/O module；Two I/O modules are divided into I/O module 1 and I/O module 2；
Maintenance terminal connects CPU module by Ethernet connecting communication module, communication module by dual port RAM 1；CPU moulds
Block connects I/O module 1 by dual port RAM 2, while connecting I/O module 2 by RS485 buses.
In each cycle of operation T, itself board working condition is sent to CPU module by I/O module 1 by dual port RAM 2；
Similarly itself board working condition is sent to CPU module by I/O module 2 by RS485 buses.
Board working condition includes：Voltage monitoring result, temperature monitoring result, interface communication situation and information processing result
Deng.
Step 2: CPU module summarizes the working condition of the working condition and itself board of two I/O module boards, and will state
Work state information after summarizing is sent to communication module by dual port RAM 1.
Step 3: communication module summarizes the work state information and itself board working condition that CPU module is sent, and lead to
It crosses Ethernet 1 and uploads to maintenance terminal.
Step 4: maintenance terminal Microprocessor System for Real Time Record operating status, completes the monitoring to platform.
System running state information can be checked by local log-on or Telnet mode.
Step 5: when being safeguarded to platform, the network interface of maintenance terminal connecting communication module uses TFTP modes
Program bag to be updated is downloaded into communication module.
Step 6: communication module parses the program bag received, and determine whether the more new procedures of communication module, if
It is to enter step seven；Otherwise, eight are entered step；
Step 7: communication module runs program more new command, program bag is cured on the memory of communication module, is laid equal stress on
New activation system realizes the update of program.
Step 8: the program bag is the more new procedures of CPU module or I/O module, program to be updated is sent to by communication module
CPU module is parsed, and judges whether the program bag is the more new procedures of CPU module, if so, nine are entered step, otherwise, into
Enter step 10；
Step 9: CPU module runs program more new command, program bag is cured on the memory of CPU module, and again
Activation system realizes the update of program.
Step 10: the program bag is the more new procedures of I/O module, CPU module will be waited for using dual port RAM 2 or RS485 buses
More new procedures are sent to corresponding I/O module, and I/O module is parsed and run program more new command, by program Solidification to be updated
On corresponding memory, and restarting systems realize the update of program.
The present invention is on maintenance terminal, and operating system upgrading and maintenance program will be under programs to be updated by tftp functionality
It is downloaded to communication module, communication module is sent program to be updated using the dual port RAM 1 between CPU according to the more new command received
To CPU module, program to be updated is issued to other I/O modules by CPU module according to more new command.In the process, if module
What is received is the program for updating this module, is not forwarding program to be updated at this time, auto-upgrade program will be being called, by journey to be updated
Sequence is cured on the memory of this module.
