Problems solved by technology
[0003] A computer system generally includes a CPU module, a communication module, and other IO modules; different programs run on modules with different functions, and the programmers used by different functional modules are also different; use different programmers to program each module sequentially. The method of program update will face a large workload, which not only increases the complexity and difficulty of system installation, debugging, upgrading and maintenance, but also is inefficient, which seriously affects the project progress and work efficiency

Embodiment Construction
[0024] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0025] The present invention realizes the state monitoring of each functional module of the system and the automatic upgrade and maintenance of the program by using the platform's own software and hardware without using a special programmer and without disassembling the platform hardware.
[0026] The method as figure 2 As shown, the specific steps are as follows:
[0027] Step 1. For each module of the computer, in each operation cycle T, the CPU module receives the board working status information of the IO module;
[0028] The present invention stipulates that a running cycle time of the platform program is T, and all boards in the platform execute their respective programs cyclically according to the running cycle T.
[0029] The various modules of the computer, such as figure 1 As shown, it includes: maintenance terminal, communication module...

The invention discloses a platform monitoring and maintaining method and belongs to the technical field of embedded systems. The method comprises the steps that firstly a CPU module summarizes workingstate information of two IO module board boards and a self board card, sends the information to a communication module, and uploads the information to a maintenance terminal; the maintenance terminaldownloads a to-be-updated program package to the communication module; if a to-be-updated program is an update program of the communication module, the communication module runs a program update instruction; if the to-be-updated program is an update program of the CPU module, the communication module sends the to-be-updated program to the CPU module, and the CPU module runs the program update instruction; if the to-be-updated program is not the update programs of the communication module and the CPU module, the CPU module sends the to-be-updated program to a corresponding IO module, and the IO module performs analysis and updates the instruction; and finally the to-be-updated program is cured in a corresponding memory, a and system is restarted to realize program update. The system installation, debugging, upgrading and maintenance efficiency is effectively improved and the maintenance time is shortened; and a system running state is recorded in real time, so that a maintainer can look up historical data conveniently.
Description
technical field [0001] The invention belongs to the technical field of embedded systems, in particular to a method for monitoring and maintaining a platform. Background technique [0002] In rail transit, aerospace and other occasions that require high reliability and high security, it is necessary to use a high-security computer system to achieve. [0003] A computer system generally includes a CPU module, a communication module, and other IO modules; different programs run on modules with different functions, and the programmers used by different functional modules are also different; use different programmers to program each module sequentially. The method of program update will face a large workload, which not only increases the complexity and difficulty of system installation, debugging, upgrading and maintenance, but also has low efficiency, which seriously affects the project progress and work efficiency.
