Description
Technical field
The present invention is mainly concerned with train operation monitoring recording unit field, refers in particular to a kind of data costume changing method being applicable to LKJ supervising device.
Background technology
LKJ supervising device (such as: LKJ2000 type), as train operation monitoring and recording device, is according to domestic transportation by railroad requirement and the train safe equipment with high-performance/cost ratio of independent development.Its main control unit monitoring record plug-in unit adopts 32 bit processor MC68332 of Freescale company production, can reach the addressing space of 16M; Use ultraviolet light erasable EPROM as the storage medium of ground line data; Use the storage medium of Nonvolatile static RAM as omnidistance log sheet of charged pool.Due to the control mode (i.e. vehicle-mounted control pattern) adopting truck-mounted computer to prestore ground line data, equipment investment cost is compared ground paving and is established dot-mode transponder to provide the mode of track data very low.In the past between 10 years, for the safe cause of Chinese Railway has made indelible contribution.
In the use procedure of LKJ supervising device, along with reasons such as each Railway Bureau circuit is newly-built, transformations, need change the outfit vehicle-mounted track data frequently.The flow process that existing LKJ data change the outfit is:
(1) LKJ2000 monitoring record plug-in unit is taken off from LKJ2000 monitor recording device;
(2) EPROM is taken off, 2 or 4 from the dismounting of LKJ2000 monitoring record plug-in unit;
(3) ultraviolet eraser is used to wipe empty EPROM;
(4) use EPROM programmer that data programming to be changed the outfit is entered EPROM;
(5) EPROM is installed back LKJ2000 monitoring record plug-in unit;
(6) finally plug-in unit is installed back LKJ2000 monitor recording device.
First, in the method that above-mentioned data change the outfit, a LKJ supervising device changes the outfit a secondary data, and at least need cost 40 minutes, its efficiency is very low.And a Railway Bureau at least has even thousands of LKJ supervising devices up to a hundred, the data that huge manpower need be spent to have carried out the overall situation change the outfit.
Secondly, change the outfit the step (2) of flow process with step (5) in above-mentioned data, be easy to because manual operation reason causes EPROM to damage, even damage LKJ2000 monitoring record plug-in unit.And EPROM is along with the increase of erasable number of times, its unfailing performance reduces gradually, and part Railway Bureau specifies that its erasable number of times must not more than 7 times, therefore cause the ratio of performance to price low, this also causes Railway Bureau all to need every year to spend many expenses for buying EPROM device, and use cost is too high.
Summary of the invention
The technical problem to be solved in the present invention is just: the technical matters existed for prior art, the invention provides a kind of operation very easy, the efficiency that changes the outfit can be improved, extend device serviceable life, method that the LKJ supervising device data that reduce use cost change the outfit.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
The method that LKJ supervising device data change the outfit, the steps include:
1. data to be changed the outfit are written to storer in the mode of file by computing machine, and carry out legitimacy checking computations to the described file having write storer, generate the legitimate verification data corresponding with this file; These legitimate verification data are written to storer in the mode of another file;
2. storer is connected with the LKJ supervising device of dead electricity, then LKJ supervising device is powered on;
3. LKJ supervising device identifies the storer be attached thereto, and verifies the legitimacy of storer; If it is determined that be legal, then perform following steps; As illegal in being judged to be, then process ends;
4. LKJ supervising device is verified according to the legitimate verification data in storer, namely treats the file changed the outfit corresponding to data and carries out legitimate verification; If it is determined that be legal, then perform following steps; As illegal in being judged to be, then process ends;
5. by data programming to be changed the outfit in the data storage areas to be changed the outfit in LKJ supervising device;
6. legitimate verification is carried out to the data changed the outfit, ensure that the data changed the outfit are legal.
As a further improvement on the present invention:
Described LKJ supervising device is connected by any one communication mode in USB, CAN, Ethernet, RS422, RS232, RS485 etc. with between storer.
NAND FLASH memory part or can the memory device of online programming is adopted in described LKJ supervising device.
Compared with prior art, the invention has the advantages that: the method that LKJ supervising device data of the present invention change the outfit, easy and simple to handle, without the need to dismantling device, installing LKJ2000 monitoring record plug-in unit and memory device, empty store part is wiped for a long time with light erasing apparatus without the need to making, therefore can greatly improve the efficiency that changes the outfit, its speed that changes the outfit can reach 30s/MB; And the not fragile device of the present invention, extend device serviceable life, reduce cost of products.
