Abstract
The invention discloses a time service method of a locomotive LKJ device. The method comprises the following steps: (1) establishing a WIFI wireless local network in a locomotive checking reservoir area and setting Beidou/GPS standard clock acquiring nodes; (2) obtaining Beidou/GPS standard clock information in real time by the Beidou/GPS standard clock acquiring nodes, and then issuing the standard clock information in the WIFI local network in the reservoir area through format conversion; (3) operating handheld terminals working in the same network environment, obtaining standard time refreshed in real time, and keeping time of the handheld terminals to be synchronous with time of a Beidou or GPS satellite in the WIFI wireless local network by a worker who enters the checking reservoir area or stands on a locomotive; (4) using a communication cable to connect a data read-write port of the LKJ device to realize time service of the LKJ device, thus ensuring that an error between an LKJ system clock and the standard time is far smaller than a standard error range in the industry.
Description
Technical field
The present invention relates to a kind of time service method of locomotive LKJ device.
Background technology
Train operation monitoring and recording device (being called for short LKJ) is the train speed control device ensureing that train operating safety is fundamental purpose, and each locomotive entering garage inspection car all needs to carry out the operations such as time service (to ensure event analysis benchmark), data download, data analysis to LKJ device.Current china railway each electricity business section mobile unit workshop is use special time corrector to obtain the GPS master clock time in office, namely first to time corrector time service, then carry on time corrector to locomotive again to the time service of LKJ device LKJ device time service method.
Existing time service method before appearance operation, first must carry out master clock time service to special time corrector, and then could appear on the scene operation.This time service method link is complicated, it is restricted to use, waste time and energy, error is compared bigger than normal, particularly easily causes non-master clock time service and increase labour intensity of doing over again because of careless omission, will affect locomotive operation safety if lack a sense of responsibility.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can obtain the standard time at any time on engine, realize the time service of LKJ device immediately, ensure LKJ system clock and the error of the standard time time service method much smaller than the locomotive LKJ device of industry standard error range.
For solving the problem, the present invention adopts following technical scheme:
A time service method for locomotive LKJ device, comprises the following steps:
1) build WIFI WLAN in locomotive inspection garage district, the Big Dipper/GPS standard time clock is set and obtains node;
2) obtain the node Real-time Obtaining Big Dipper/GPS standard time clock information by the Big Dipper/GPS standard time clock, then standard time clock information is distributed in the WIFI LAN of reservoir area by format conversion;
3) staff is entering on inspection garage district or locomotive, and the handheld terminal worked under operating in consolidated network environment, obtains the standard time of refreshing in real time, keep the handheld terminal time under WIFI WLAN with the time synchronized of the Big Dipper or gps satellite;
4) utilize communication cable to connect LKJ device reading and writing data mouth, realize LKJ device and realize time service.
Further, the communications protocol with LKJ device is embedded with in described handheld terminal.
Further, described handheld terminal possesses the download of LKJ data and data wireless transfer function.
Beneficial effect of the present invention is: under WIFI WLAN, obtain the standard time by handheld terminal at any time, then after implementing LKJ device time service method, ensure that the error of LKJ apparatus system clock and standard time is far smaller than industry standard error range.Change the LKJ device time service mode that original railway systems fall behind.Particularly avoid former working method because slipping non-master clock time service increase labour intensity of doing over again, or cause because lacking a sense of responsibility time deviation large and affect locomotive operation safety.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the time service method of a kind of locomotive LKJ of the present invention device.
Wherein, 1-WIFI WLAN; The 2-Big Dipper/gps satellite; The 3-Big Dipper/GPS standard time clock obtains node; 4-handheld terminal; 5-locomotive; 6-handheld terminal and the Big Dipper/GPS standard time clock obtain inter-node communication.
Embodiment
As shown in Figure 1, a kind of time service method of locomotive LKJ device, comprises the following steps:
1) examine garage district at locomotive 5 and build WIFI WLAN 1, the Big Dipper/GPS standard time clock is set and obtains node 3;
2) obtain the node 3 Real-time Obtaining Big Dipper/GPS standard time clock information by the Big Dipper/GPS standard time clock, then standard time clock information is distributed in reservoir area WIFI LAN 1 by format conversion;
3) staff is entering on inspection garage district or locomotive 5, the handheld terminal 4 worked under operating in consolidated network environment, obtain the standard time of refreshing in real time, keep handheld terminal 4 time in the time synchronized of WIFI WLAN 1 time and the Big Dipper or gps satellite 2;
4) utilize communication cable to connect LKJ device reading and writing data mouth, realize LKJ device and realize time service.
The communications protocol with LKJ device is embedded with in described handheld terminal 4.
Described handheld terminal 4 possesses LKJ data and downloads and data wireless transfer function.
Beneficial effect of the present invention is: under WIFI WLAN, obtain the standard time by handheld terminal at any time, then after implementing LKJ device time service method, ensure that the error of LKJ apparatus system clock and standard time is far smaller than industry standard error range.Change the LKJ device time service mode that original railway systems fall behind.Particularly avoid former working method because slipping non-master clock time service increase labour intensity of doing over again, or cause because lacking a sense of responsibility time deviation large and affect locomotive operation safety.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in this with within novel protection domain.
