Problems solved by technology

Because there is no parameter adjustment service or high cost is required, and the software has no source code, no design documents, only executable files, the acquisition of the algorithm state in the software, the modification of each parameter, and the adaptation to the external environment, etc., utilize the existing The method is difficult to realize, so it is difficult to adjust the parameters, which brings a lot of inconvenience to the operation, use and maintenance guarantee

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, the QNX operating system general non-source code software parameter adjustment system of the present invention includes a kernel resident program, terminal display software and parameter adjustment auxiliary software.

[0029] The implementation process of the above-mentioned QNX operating system general non-source code software parameter adjustment system is as follows:

[0030] S1. Use reverse engineering method to obtain the meaning and physical address represented by each algorithm and parameter of the equipment software through disassembly, decompilation, and binary comparison analysis.

[0031] S2. Through the algorithm simulation, the adaptability of the equipment software algorithm and parameters is obtained when the environment changes, that is, the simulation calculation obtains the optimal...

Abstract

The object of the present invention relates to a QNX operating system general non-source code software parameter adjustment method and its system, and the realization method of the system. The parameter adjustment method of the present invention is injected into the kernel by adding a resident third-party service program, and directly obtains all the data under the ring3 authority. Various data inside the program are output through the FLEET or QNET network, and at the same time, the LMF and ELF file formats under the QNX operating system are analyzed, and binary-level parameter adjustments are performed.

Description

technical field [0001] The invention relates to parameter adjustment of passive industrial control software, in particular to a QNX operating system general passive software parameter adjustment method, a system thereof, and a method for realizing the system. Background technique [0002] With the continuous evolution of technology, the algorithms contained in various types of equipment software are becoming more and more complex, and the adaptation of software to the external environment requires a large number of parameters. These parameters are usually stored inside the software. If the software itself or the external environment state changes, its adaptation parameters must be adjusted. Because there is no parameter adjustment service or high cost is required, and the software has no source code, no design documents, only executable files, the acquisition of the algorithm state in the software, the modification of each parameter, and the adaptation to the external enviro...
