In the disclosed method of obtaining data of above-described embodiment, if a plurality of terminal equipments are in wake-up states, and the data acquisition software of automatically giving host computer sends the real time data of up till now terminal equipment collection, in advance a plurality of terminal equipments are numbered, and to be numbered for the data of each terminal equipment collection, terminal equipment can leave the Frame numbering that gathers in self storage device of reference numeral in order, after data acquisition in the corresponding terminal equipment is complete, can carry out the collection of next terminal equipment real time data according to the order of numbering.

When determining that loss of data does not occur, then enter normal flow, so-called old process is exactly real time data to the first memory space that storage is obtained in fact, and client device can obtain the complete real time data that is stored to the first memory space.

In order to gather easily real time data, when Frame is numbered, need to select best ordered series of numbers, according to certain rule the real time data Frame is numbered.Therefore, another embodiment of the present invention also discloses a kind of method of obtaining data, as shown in Figure 2, may further comprise the steps:

Wherein, described Frame is numbered the arithmetic progression with default tolerance;

Wherein, step S102 comprises:

Difference between the Frame numbering of described first data of S1021, described the first data of calculating current reception and a upper reception;

S1032, described numbering is defined as the Frame numbering of described obliterated data;

The Frame numbering of S1033, the described missing data of storage is to second memory space corresponding with described terminal equipment;

In the disclosed method of obtaining data of present embodiment, if the Frame numbering is decided to be the arithmetic progression with default tolerance, for example from 1 to N natural sequence, when receiving terminal apparatus sends, carry the first data of predefined Frame numbering, data 1, data 2, data 3 ... data N, and store described the first data to first memory space corresponding with described terminal equipment, for example, the data that are stored to the first memory space are data 1, data 2, data 3, at this moment, if terminal equipment is drawn out the storehouse with wireless network, perhaps equipment cuts off the power supply suddenly, host computer just can not collect the part real time data, when again recovering normal condition, the first data that carry predefined Frame numbering that again can receiving terminal apparatus send this moment, data 11 ... data N, calculate the first data of current reception, the first data of data 10 and a upper reception, difference between the Frame numbering of data 3, difference is 7, judge that described difference is not tolerance 1, then determine to occur loss of data, Frame numbering according to the first data, determine the Frame numbering of missing data, and the Frame numbering of storage missing data is to second memory space corresponding with terminal equipment, this is, just can determine that the Frame numbering of missing data is between 3 and 10, be respectively 4,5,6,7,8,9, the Frame numbering that these numberings is decided to be missing data, be stored to second memory space corresponding with terminal equipment, send described first data of current data group when described terminal equipment after, the Frame numbering that reads described missing data from described the second memory space is last, the missing data that transmission carries the Frame numbering of described missing data obtains instruction to corresponding terminal equipment, receives described terminal equipment and responds the missing data of described instruction transmission and it is stored to described the first memory space.

Certainly, the Frame numbering can also be decided to be the even number ordered series of numbers, when Frame is numbered the even number ordered series of numbers, real time data is data 2, data 4, data 6 ... data 2N, the difference between numbering with the Frame of the first data of a upper reception by the first data of calculating current reception so judges whether difference is tolerance 2, if, then loss of data does not occur in data, if not described tolerance 2 data has then occured lost.And then the Frame of definite missing data numbering, be stored to the second memory space, the Frame numbering that reads described missing data from the second memory space is last, the missing data that transmission carries the Frame numbering of described missing data obtains instruction to corresponding terminal equipment, receives described terminal equipment and responds the missing data of described instruction transmission and it is stored to described the first memory space.

Sometimes, the difference that the first data by calculating current reception in above-described embodiment and the Frame of the first data of a upper reception are numbered judges that whether difference is the tolerance to arithmetic progression, if then data do not lack, if not, shortage of data then.But can miss by this method the Frame numbering of a part of missing data, for the Frame that replenishes the missing data of missing is numbered to the second memory space, another embodiment of the present invention also discloses a kind of method of obtaining data, as shown in Figure 3, may further comprise the steps:

S102, judge whether to occur loss of data according to the Frame of described the first data numbering;

Wherein, step S102 comprises:

S1022, judge whether described difference is described tolerance, if, determine loss of data does not occur, then enter normal flow, otherwise, determine to occur loss of data, then execution in step S103;

Wherein, step S103 comprises:

After step S103, before the step S104, also comprise:

S107, gather pre-stored in terminal equipment, carry the second data of the first minimum data frame number;

Carry described first data of the second minimum data frame number in S108, collection the first memory space;

S109, obtain the first minimum data frame number and the second minimum data frame number, and calculate the difference between the first minimum data frame number and the second minimum data frame number;

S110, judge that described difference is whether less than zero, when the difference between the first minimum data frame number and the second minimum data frame number less than zero the time, loss of data then occurs, execution in step S111, when the difference between the first minimum data frame number and the second minimum data frame number is not less than zero, further losing of data, execution in step S104 then do not occur;

S111, determine between the first minimum data frame number and the second minimum data frame number and differ the numbering of the integral multiple of described tolerance with the first minimum data frame number, deposit described numbering and the first minimum data frame number in second memory space corresponding with described terminal equipment.

In the disclosed method of obtaining data of present embodiment, difference between the Frame numbering of the first data of the Frame numbering of the first data of calculating current reception and a upper reception, and judge whether described difference is described tolerance, after obtaining the Frame numbering of a part of missing data, gather pre-stored in terminal equipment, carry the second data of the first minimum data frame number, gather simultaneously described the first data that carry the second minimum data frame number in the first memory space, obtain the first minimum data frame number and the second minimum data frame number, and calculate difference between the first minimum data frame number and the second minimum data frame number, for example, the Frame of the real time data of storing in the initial time terminal equipment is numbered 1 to 50, the Frame that sends to data acquisition software is numbered 35 to 45, the Frame of the second data that carry the first minimum data frame number that gather this moment is numbered 31, the Frame that carries described first data of the second minimum data frame number in the first memory space that gathers is numbered 35, difference between the first minimum data frame volume the 31 and second minimum data frame number 35 is less than zero, therefore, losing of data occured as can be known, determine between 31 to 35, and number for the Frame of missing data with 31 numbering and the first minimum data frame numbers 31 that differ the integral multiple of tolerance 1, this moment, the Frame of missing data was numbered 31,32,33,34, and deposit these four data frame numbers in second memory space corresponding with described terminal equipment.

In like manner, we also need the maximum data frame number in the terminal equipment and the maximum data frame number in the real-time data base are compared, and have judged whether to occur further losing of data.Similar to the above embodiments, another embodiment of the present invention also discloses a kind of method of obtaining data, as shown in Figure 4, except comprising step S101, S102, S103, S104, S105, S106, wherein, step S102 comprises S1021, S1022, and step S103 comprises S1031, S1032, S1033;

S114, obtain the first maximum data frame number and the second maximum data frame number, and calculate the difference between the first maximum data frame number and the second maximum data frame number;

S115, judge described difference whether greater than zero, if further losing of data then occured greater than zero in described difference, execution in step S116, if described difference is not more than zero, upper further losing of data, then the execution in step S104 of occuring then;

S116, determine between the first maximum data frame number and the second maximum data frame number and differ the numbering of the integral multiple of tolerance with the first maximum data frame number, deposit described numbering and the first maximum data frame number in second memory space corresponding with described terminal equipment.

In the disclosed method of obtaining missing data of above-described embodiment, difference between the Frame numbering of the first data of the Frame numbering of the first data of calculating current reception and a upper reception, and judge whether described difference is described tolerance, after obtaining the Frame numbering of a part of missing data, also can gather pre-stored in described terminal equipment, carry the second data of the first maximum data frame number, gather simultaneously the first data that carry the second maximum data frame number in the first memory space, obtain described the first maximum data frame number and described the second maximum data frame number, and calculate the difference between described the first maximum data frame number and the second maximum data frame number.For example, at initial time, the Frame of the real time data of storing in the terminal equipment is numbered 1 to 50, carry the first data of predefined Frame numbering when transmission, and store described the first data to first memory space corresponding with described terminal equipment, the Frame of storing in terminal equipment is numbered 35 to 50, what collect like this is pre-stored in described terminal equipment, the Frame that carries the second data of the first maximum data frame number is numbered 50, and the Frame in the first memory space is numbered 1 to 34, then the second maximum data frame number is 34, the difference of calculating gained is 16, described difference is greater than zero, then determine to have occured further losing of data, determine that the Frame numbering of missing data is between 34 to 50, and with 50 numbering and described the first maximum data frame numbers that differ the integral multiple of tolerance 1, therefore the Frame of missing data is numbered 35,36,37,38,39,40 ... 50, again these 16 data frame numbers are stored to corresponding the second memory space with terminal equipment.

Above-mentioned four embodiment are disclosed to be obtained in the method for data, terminal equipment is after receiving the real time data that extraneous input advances, within the regular hour, terminal equipment does not receive external data, after namely the first data of current group of storage being sent, there are not new data to enter the storage device of terminal equipment.But in general, terminal equipment is in the state that upgrades its data storehouse often always, the extraneous new real time data that constantly carries the Frame numbering to the terminal equipment input.Therefore, in order to replenish the Frame numbering of the missing data that does not deposit the second memory space in, another embodiment of the present invention also discloses a kind of method of obtaining missing data, as shown in Figure 5, except comprising step S101, S102, S103, S104, S105, S106, wherein, step S102 comprises S1021, S1022, and step S103 comprises S1031, S1032, S1033;

Described terminal equipment continues receive data, after step S103, before the step S104, also comprises:

S117, gather pre-stored in described terminal equipment, carry the second data of the first minimum data frame number, the first maximum data frame number;

Carry the first data of the second maximum data frame number in S118, described the first memory space of collection;

S119, obtain described the first minimum data frame number, the first maximum data frame number and described the second maximum data frame number, calculate difference between described the first minimum data frame number and described the second maximum data frame number;

S120, judge that whether described difference is greater than zero, and whether be not described tolerance, if difference is not described tolerance between described the first minimum data frame number and described the second maximum data frame number, and described difference is greater than zero, then data have occured further to lose, execution in step S121, if difference is described tolerance between described the first minimum data frame number and described the second maximum data frame number, perhaps described the second maximum data frame number is greater than described the first minimum data frame number and less than described the first maximum data frame number, data do not occur further to lose, then execution in step S104;

S121, determine between described the first minimum data frame number and described the second maximum data frame number and differ the numbering of described tolerance integral multiple with described the second maximum data frame number, deposit described numbering in second memory space corresponding with described terminal equipment;

Can find out from the disclosed method of obtaining data of present embodiment, when terminal equipment continues ceaselessly at receiving real-time data, when self stores the storage device continuous updating of real time data, send described first data of current data group when terminal equipment after, the Frame that is stored to the second memory space is numbered the Frame numbering of missing data, but, this moment, the Frame numbering that is stored to the second memory space is numbered and be not only to the Frame of missing data, and we also need the Frame numbering of the missing data of the second memory space is replenished.Therefore, at first gather pre-stored in described terminal equipment, carry the first minimum data frame number, the first maximum data frame number the second data, gather the first data that carry the second maximum data frame number in described the first memory space.For example, at initial time, the Frame of the real time data of the preservation in the terminal equipment is numbered 1 to 100, now be sent in the data acquisition software of host computer 1 to 10, also machine is to the data of its input outside receiving when terminal equipment sends real time data, and the external world is numbered 101 to 110 to the Frame of the data of its input.In general, the device of above-mentioned the first memory space, the second memory space and terminal equipment self preservation real time data can be defined as the database of save data.As everyone knows, the internal memory that terminal equipment self is preserved the database of real time data is certain, therefore, when the external world inputs data to its, Frame numbering in the real-time data base becomes 11 to 110, and the change of Frame numbering is so that the method change of follow-up additional missing data to the second memory space.

Frame in the terminal equipment is numbered 11 to 110, therefore, the first maximum data frame number is 110, the first minimum data frame number is 11, and the second maximum data frame number is 10, can get thus, difference is tolerance 1 between the first minimum data frame number and described the second maximum data frame number, then data do not occur further to lose, get final product execution in step 104, send described first data of current data group when described terminal equipment after, read the Frame numbering of described missing data from described the second memory space.

For example, at initial time, the Frame of the real time data of the preservation in the terminal equipment is numbered 1 to 100, now be sent in the data acquisition software of host computer 1 to 10, and the Frame that is stored in the first memory space to be numbered only be 1 to 8, also machine is to the data of its input outside receiving when terminal equipment sends real time data, and the external world is numbered 101 to 110 to the Frame of the data of its input.Therefore, when the external world inputs data to its, Frame numbering in the real-time data base becomes 11 to 110, the first maximum data frame number is 110, the first minimum data frame limit is numbered 11, the second maximum data frame number is 8, difference 3 is not tolerance 1 between the first minimum data frame number and described the second maximum data frame number, and difference is greater than zero, then can specified data occur further to lose, determine between the first minimum data frame number 11 and the second maximum data frame number 8, and differ the numbering of tolerance 1 integral multiple with the second maximum data frame number 8, describedly be numbered 9 and 10, deposit these two numberings in second memory space corresponding with described terminal equipment again, then execution in step 104.

For another example, at initial time, the Frame of the real time data of the preservation in the terminal equipment is numbered 1 to 100, now be sent in the data acquisition software of host computer 1 to 15, and the Frame numbering that is stored in the first memory space also is 1 to 15, the Frame of follow-up reception is numbered 101 to 105, therefore, at this moment, the Frame of preserving in the real-time data base in the terminal equipment is numbered 5 to 105, therefore, the first maximum data frame number is 105, the first minimum data frame number is 5, the second maximum data frame number is 15, can determine, the second maximum data frame number 15 is greater than the first minimum data frame number 5, and less than the first maximum data frame number 105, at this moment, data do not occur further to lose yet, execution in step 104 and subsequent step, send described first data of current data group when described terminal equipment after, read the Frame numbering of described missing data from described the second memory space, the missing data that transmission carries the Frame numbering of described missing data obtains instruction to corresponding terminal equipment, receives described terminal equipment and responds the missing data of described instruction transmission and it is stored to described the first memory space.

In the disclosed method of obtaining data of above-described embodiment, reading the Frame numbering of missing data, the missing data that also will carry the Frame numbering of described missing data simultaneously obtains instruction to corresponding terminal equipment, the disappearance numbered list of Data Update the second memory space that sends according to terminal equipment, concrete grammar is deleted from the second memory space for the Frame numbering that will read, the Frame numbering that perhaps will read is put and is indicated the position, until reading, all missing datas finish and are saved to the first memory space, guarantee the integrality of real time data, cause disorder in case repeat to read the transmission identical data to program threads, and then bring the inconvenience in the work.
