Specific embodiment
Specific embodiments of the present invention are described in detail below in conjunction with attached drawing.It should be understood that described herein
Specific embodiment be merely to illustrate and explain the present invention, be not intended to restrict the invention.
Embodiment 1
Fig. 6 shows the flow chart of the data earth-filling method of embodiment according to the present invention.With continued reference to Fig. 1 and Fig. 4,
Data receiver break in data communication the data that receive of front and back as shown in Figure 1, data collection terminal recorded comprising losing
In the case that the data file of data is as shown in Figure 4, using the data earth-filling method of the embodiment of the present invention, firstly, from data
Collection terminal obtains the data file including losing data as shown in Figure 4, then, data receiver is extensive in data communication
The acquisition moment at the acquisition moment [13:20:06] for the data being initially received after multiple and each data in the data file obtained
It is compared, since only one data acquires moment [13:20:06] in the data file of acquisition, the data that will acquire
Data acquisition moment [13:20:06] in file is determined as the end point of loss of data.
Although illustrating only only one data acquisition moment [13:20:06] in the data file of acquisition in the present embodiment
The case where, still, do not invent without being limited thereto.For example, when data collection terminal clock data receiver and data collection terminal it
Between data communication interrupt during by back (that is, to the past) calibrate or adjust when, if obtain data file in exist it is more
A data acquire moment [13:20:06], then at least one channel by data receiver in the case where acquiring moment [13:20:06]
Data are compared with the data for the respective channels that the acquisition moment in the data file of acquisition is [13:20:06], for example, will
Data receiver is at the acquisition moment acquired in the data of channel CH1 and the data file of acquisition under moment [13:20:06]
The data of the channel CH1 of [13:20:06] are compared, thus the data of each channel in the data file that will acquire with number
The identical acquisition moment [13:20:06] of data according to respective channels of the receiving end in the case where acquiring moment [13:20:06] is determined as
The end point of loss of data.
It is preferred here that the data and acquisition of all channels by data receiver in the case where acquiring moment [13:20:06]
Data file in the acquisition moment be that the data of respective channels of [13:20:06] are compared, thus the data text that will acquire
The data of all channels in part are identical as the data of respective channels of the data receiver in the case where acquiring moment [13:20:06]
The acquisition moment [13:20:06] be determined as the end point of loss of data.
Then, by data receiver in data communication break before finally receive data the acquisition moment [13:20:
01] it is compared with the acquisition moment of each data in the data file obtained, since there are two in the data file of acquisition
Moment [13:20:01] is acquired (that is, data communication of the clock of data collection terminal between data receiver and data collection terminal
Back calibrated or adjusted during interruption), therefore, further by data receiver in the case where acquiring moment [13:20:01] at least
The acquisition moment in the data of one channel and the data file of acquisition is that the data of the respective channels of [13:20:01] are compared
Compared with for example, the data [0.0287] of the channel CH1 by data receiver in the case where acquiring moment [13:20:01] and the data obtained
The acquisition moment in file is that the data [0.0287] of the channel CH1 of [13:20:01] and [1.1875] are compared, the implementation
In example, since the data for the channel CH1 that two acquisition moment in the data file of acquisition are [13:20:01] are different, and one
Acquire moment [13:20:01] under channel CH1 data [1.1875] be different from data receiver data acquire the moment [13:
20:01] under channel CH1 data [0.0287], and another acquisition moment [13:20:01] under channel CH1 data
[0.0287] identical as data [0.0287] of channel CH1 of the data receiver under data acquisition moment [13:20:01], because
This, the data of the channel CH1 in the data file that will acquire are that data acquisition moment [13:20:01] of [0.0287] is determined as
The starting point of loss of data.
But if two acquisition moment in the data file obtained are the data phase of the channel CH1 of [13:20:01]
Together, and the data of channel CH1 of the data receiver in the case where acquiring moment [13:20:01] are equal to, then further by data receiver
End acquire the acquisition moment in the data of channel CH2 and the data file of acquisition under moment [13:20:01] for [13:20:
01] data of channel CH2 are compared, and so on.
Certainly, it if only one data acquires the moment as [13:20:01] in the data file obtained, will acquire
Data acquisition moment [13:20:01] in data file is determined as the starting point of loss of data.
In the present embodiment, it is preferable that first determine the end point of loss of data, then determine the starting point of loss of data.This is
Because although illustrating only the starting point of loss of data and the end point of loss of data in the present embodiment positioned at identical data text
Situation in part, still, the invention is not limited thereto.In general, data collection terminal can be formed according to scheduled data partition method
Data file, therefore, the starting point of the loss of data of data receiver and the end point of loss of data are possible in data collection terminal
In different data files.In this case, for the first time from data collection terminal obtain data file when, include loss of data
The data file of end point may be formed not yet, therefore may not include in the data file obtained for the first time includes that data are lost
The data file of the end point of mistake, at this point, can not find the end of loss of data if the starting point of loss of data has first been determined
Point.It is therefore preferred that first determine the end point of loss of data, and if not finding the end point of loss of data, a period of time
Data file is obtained from data collection terminal again afterwards, until finding the end point of loss of data, at this point, the data text obtained
It necessarily include the data file of the starting point of loss of data in part, that is, the inevitable beginning that can also find loss of data
Point.
Specifically, in the starting point of the loss of data of data receiver and the end point of loss of data in data collection terminal position
In the case where in different data files, the end point of loss of data is first determined, it is then possible in acquisition by same batch
Data (that is, associated data) be formed by data file the starting point for obtaining loss of data.In general, by same a batch
Secondary data, which are formed by data file, may have certain identical attributes, for example, by being formed by with a batch of data
The possible data file identifier (that is, data file ID) having the same of data file, therefore, in the knot that loss of data has been determined
After beam spot, there can be same alike result (for example, data file ID) with the data file of the end point comprising loss of data
The starting point of loss of data is determined in data file.
Fig. 7 shows the loss data determined using the data file of data earth-filling method of the invention according to Fig.4,
Range.As shown in fig. 7, in the starting point for determining loss of data for its corresponding channel CH1's in the data file of acquisition
Data are the acquisition moment [13:20:01] of [0.0287] and in the case that the end point of loss of data are [13:20:06],
The data between the starting point of the loss of data in data file and the end point of loss of data that then will acquire are determined as losing
The range of data is clearly different from the range of the loss data determined in Fig. 5 using the data earth-filling method of the prior art.
Then, the data in the range of extracting identified loss data in the data file of acquisition, and filled up
To the loss of data part of data receiver, that is, fill up before data receiver breaks in data communication and finally receive
The number that data (that is, the data of acquisition moment for [13:20:01]) and data receiver are initially received after data communication recovery
According between (that is, the data of acquisition moment for [13:20:06]), data are completely received to present in data receiver, such as figure
Shown in 8.
