By arranging detection module and control module, can judge that train tail host is normal power down or unexpected momentary power failure exactly, and start train tail host in different ways for different power-off reasons, efficiently avoid the Problem of Failure caused due to the momentary power failure of the power supply of train tail host.
For above-mentioned start up system, additionally provide more than one in the embodiment of the application and state the starting method that start up system starts train tail host, as shown in Figure 3, this starting method comprises:
Step S310, judge whether described train tail host set up corresponding relation with driver's control convenience before activation according to the status information during operation that train tail host is stored before activation, then start described train tail host with the first Starting mode if not, if then perform step 2.
Step S320, judge whether described train tail host before activation power supply hit occurs according to the temporal information during operation that train tail host is stored before activation, then start described train tail host with the second Starting mode if not, if then start described train tail host with the 3rd Starting mode.
Concrete, determine whether set up man-to-man corresponding relation with driver's control convenience in the operational process of train tail host before this starts.If train tail host did not set up corresponding relation with driver's control convenience before this starts, illustrated in train tail host operational process before activation and be not in actv. mode of operation, therefore started train tail host according to the first Starting mode.First Starting mode specifically comprises, and first carries out Initialize installation to train tail host, then the engine number of locomotive sets up the corresponding relation of train tail host and driver's control convenience belonging to driver's control convenience.
In the embodiment of the application, according to the status information during operation that train tail host is stored before activation, whether corresponding relation is established to train tail host and driver's control convenience and judge.Concrete, train tail host, in the process run, needs the status information of the equipment at different time reference point place to store.The status information of equipment can comprise the time etc. that whether train tail host corresponding with time reference point establishes corresponding relation with driver's control convenience, sets up the engine number of locomotive belonging to driver's control convenience of corresponding relation with train tail host, whether train tail host is carrying out air draft braking and air draft is braked.Further, adopt fixed time interval to read time reference point, time gap is chosen according to the processing capacity of train tail host and accuracy of detection.Strong for processing capacity, accuracy of detection requires high application scenario, can choose little time gap, namely reads time reference point more.For example, time gap is generally chosen in the scope of 1 ~ 2000ms.Be the example of the temporal information that stores of train tail host and status information shown in table 1, time gap is taken as 500ms.
The temporal information that table 1 stores and status information
It should be noted that, the status information utilizing the time reference point place nearest apart from this run up time is only needed when judging the annexation of train tail host, therefore only need to preserve up-to-date record in real time, so the status information of the storage shown in table 1, not be stored in storage equipment simultaneously, but with the status information of a replacement real-time update storage above below.
If train tail host there occurs power-off when (3:10:24:800), Article 2 recorded information then in table 1 is the final status information stored, when train tail host starts again, can judge that train tail host did not set up corresponding relation with driver's control convenience before this starts according to whether establishing corresponding relation, then start train tail host with the first Starting mode.If train tail host there occurs power-off when (3:10:25:500), Article 3 recorded information then in table 1 is the final status information stored, can judging that train tail host is in actv. mode of operation before the power-off of the last time, therefore continuing to judge that the power-off of train tail host the last time is normal power down or unexpected momentary power failure with regard to needing.
In the embodiment of the application, utilize and judge whether to there occurs power supply hit to again starting the power-off time experienced from power-off.Be specially, first read the time that this starts, then temporal information when reading stored the before activation operation of train tail host, the difference calculating two times obtains power-off time.If power-off time is greater than default power-off time, then judge train tail host before activation as normal power down, if power-off time is less than or equal to default power-off time, then judge that train tail host there occurs power supply hit before activation.The power-off time △ T preset chooses according to the operational administrative specification of the performance of train tail host power-supply system and locomotive.Such as, if the time that the power supply generation hit of train tail host restores electricity again is shorter, then needing to choose less setting-up time △ T could detect momentary power failure effectively.For example, carry out statistical analysis according to the power supply hit of train tail host, obtaining train tail host from generation power supply hit to the averaging time restored electricity again is 2s, so just needs △ T to be set in be less than in 2s.General, the power-off time △ T preset chooses in the scope of 1 ~ 10s.
Further, when train tail host normal power down, illustrate that previous operation task completes, now start train tail host with the second Starting mode.Concrete, first eliminate the corresponding relation of train tail host and the driver's control convenience set up before starting, mainly comprise the status information etc. of Initialize installation when removing last time operation and storage.Carry out Initialize installation to train tail host again, finally belonging to driver's control convenience, the engine number of locomotive sets up man-to-man corresponding relation between train tail host and driver's control convenience.There occurs power supply along time disconnected at train tail host, illustrate that previous operation task is interrupted accidentally, now start train tail host with the 3rd Starting mode.Concrete, first belonging to the driver's control convenience setting up corresponding relation with train tail host before starting, the engine number of locomotive sets up the corresponding relation of train tail host and driver's control convenience, the coupled condition namely before recovery power-off between train tail host and driver's control convenience.The status information during operation that then reading train tail host is stored before activation, starts train tail host and makes it continue to run according to state that status information stores.
In the embodiment of the application, by the analysis to the running state before train tail host power-off, judge that train tail host is normal power down or unexpected momentary power failure, and start train tail host in different ways for different power-off reasons, efficiently avoid the Problem of Failure caused due to the momentary power failure of the power supply of train tail host.
Although the embodiment disclosed by the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technical personnel in any the utility model art; under the prerequisite not departing from the spirit and scope disclosed by the utility model; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
