Abstract
A data safety copying method of an on-line programmer comprises the steps that first, when a PC is used for writing data files into the on-line programmer, an identity recognition verification file is generated for the written data files in the on-line programmer, creating time, modifying time and original file names of the data files are recorded in the identity recognition verification file; second, when the on-line programmer carries out data updating on equipment to be updated, the equipment to be updated first reads the data files in the on-line programmer and obtains creating time and modifying time of the data files, creating time and modifying time of the data files and creating time and modifying time of the identity recognition verification file of the data files are compared for verification, and after time is legal by verification, the on-line programmer carries out data updating on the equipment to be updated.
Description
Technical field
The present invention relates to the data security update method of a kind of online programming device and equipment to be updated.
Background technology
Train operation monitoring device (LKJ) is the important component part of Train operation control system, is for preventing that train overrun a signal, operation hypervelocity accident and donkey engine driver (containing motor train unit driver) from improving the important traffic safety equipment of maneuvering capability.LKJ vehicle-mounted data is that LKJ controls the basis of function realization and the foundation of operating analysis.The accuracy of LKJ vehicle-mounted data is prerequisite and the guarantee of monitoring safe train operation.Therefore, the reliability of LKJ vehicle-mounted data renewal process, security are had to very high requirement.
When utilizing online programming device to carry out Data Update to monitoring record plug-in unit, because online programming device can be to a plurality of monitoring record plate copied files.Like this, if monitoring record plate is not legitimate device, there is like this risk of mistake copy.
The patent No. is the patent of invention of CN200580030465.0, its objective is for preventing from repeating copy security and the legitimacy of the i.e. number of times of restriction copy, rather than assurance copy.Its measure of taking is: by judgement destination media device id, copy time and random number, judge.
Summary of the invention
The object of this invention is to provide a kind of mistake copy, data security copy method of the online programming device guaranteeing data security of preventing.
For achieving the above object, the present invention is by the following technical solutions:
A kind of data security copy method of online programming device, it comprises: step 1, while utilizing PC to online programming device data writing file, in online programming device, be the identification authenticating documents of Generating Data File writing, in described identification authenticating documents, record the raw filename of creation-time, modification time and the data file of data file; Step 2, online programming device is treated and is updated the equipment while carrying out Data Update, first equipment to be updated read the data file in online programmable device and obtain creation-time and the modification time of data file, and by the checking of comparing of the creation-time in the creation-time of data file and modification time and its identification authenticating documents and modification time, after empirical tests is legal, online programming device carries out Data Update to equipment to be updated.
Utilize PC to before online programming device data writing file, first the legitimacy of verification online programming device.
In described step 1, the identification authenticating documents of the content data file writing and generation is all encrypted and checking treatment; Correspondingly, in step 2, after checking is legal, online programming device is first decrypted and checking treatment content data file and identification authenticating documents, finally carries out Data Update again.
Described checking treatment comprises that CRC check is processed and retaking of a year or grade is processed, after described retaking of a year or grade is processed and referred to that online programming device data writing file successfully, by the verification of comparing of the file on the data file writing and computing machine.
The document format data that PC writes to online programming device, is the file layout that equipment to be updated can be identified.
Adopt the present invention of technique scheme, in order to prevent artificial mistake copy, by when source file generates, produce a supporting identification authenticating documents with it, record creation-time, the modification time of source file, raw filename of source file etc., and to identification authenticating documents content-encrypt, after only having source file and the check of identification authenticating documents legal, monitoring record plate just upgrades source file.
Accompanying drawing explanation
Fig. 1 is process flow diagram of the present invention.
Fig. 2 is the process flow diagram of online programming management software.
Embodiment
As shown in Figure 1, a kind of data security copy method of online programming device, it comprises the following steps:
Step 1, LKJ online programming management software is housed in PC, this LKJ online programming management software be by LKJ is used section control the compiling of parameter making software write sheet file and the compiling of LKJ basic data making software write sheet file, boot file adds after file identification and check information, be written in LKJ online programming device with configuration file and clear one of (reading) ferroelectric memory command file, and daily record manages to LKJ2000 monitoring record H update of plug-in, its course of work as shown in Figure 2.First, the legitimacy of this management software verification online programming device, differentiates equipment by device identifier, manufacturer and built-in instruction response value, prevents that file from writing miscellaneous equipment, guarantees only to write the LKJ online programming device that our company produces.After checking this online programming device legal, utilize the online programming management software of PC to online programming device data writing file, and the form of data writing file is the file layout that equipment to be updated can be identified.For the present invention, equipment to be updated is LKJ2000 monitoring record H plug-in unit, so, to writing in files such as LKJ vehicle-mounted control file, LKJ vehicle-mounted basic data files, should generate the file that LKJ2000 monitoring record H plug-in unit can be identified by agreement form.
Simultaneously, identification authenticating documents of Generating Data File for writing in online programming device, in described identification authenticating documents, record the important informations such as raw filename of creation-time, modification time and the data file of data file, and identification authenticating documents content is encrypted and checking treatment.By identification authenticating documents, prevent from by artificial copy mode, file directly being copied in LKJ online programming device and being gone, realize the object that file security upgrades.
Step 2, after equipment to be updated is connected with online programming device, equipment to be updated sends and writes instruction to online programming device, this writes the write-protect that online programming device is removed in instruction, then first equipment to be updated read the data file in LKJ online programming device and obtain creation-time and the modification time of data file, and by the checking of comparing of the creation-time in the creation-time of data file and modification time and its identification authenticating documents and modification time, and file content is carried out to CRC check, after empirical tests is legal, online programming device is first decrypted and checking treatment data file and identification authenticating documents, final online programmable device carries out Data Update to equipment to be updated, and on LKJ online programming device, produce and upgrade LOG journal file.LKJ online programming device connects upper PC computer, imports and upgrades LOG daily record in software, can viewing files upgrade result.
It should be noted that, above-mentioned checking treatment comprises that CRC check is processed and retaking of a year or grade is processed, and described retaking of a year or grade processing refers to after online programming device generated data file, by the verification of comparing of the file on data file and computing machine.
