Further understand to have to the present invention, of the invention is deposited for GNSS receiver data below with reference to Fig. 3
The data storage and management method of storage management system is described in detail.
As a specific embodiment of the invention, GNSS receiver data storage management system is used for storage management three
The time interval of the data of time cycle, three time cycles is all the same, the resolving period that time interval is 1.5 times.This implementation
The data storage and management method of example specifically includes following steps.
Step 1 is received the main configuration parameters of GNSS receiver core board 100 and GNSS by microprocessor 10
The parameter information of machine is stored to the first storage unit 20, wherein the main configuration parameters master of GNSS receiver core board 100
It to be transmission frequency, the baud rate of communication, the output format of data of observation data and almanac data；The parameter of GNSS receiver
Information is mainly the factory information of GNSS receiver and the resolving cycle T of data etc., and the factory information of GNSS receiver includes version
This number, product number and protocol version.
Step 2, microprocessor 10 receive the T1 to Tn in period first time that GNSS receiver core board 100 transmits
The data at moment simultaneously store data to the second storage unit 30.Specifically, GNSS receiver, which receives, comes from GNSS receiver
The initial data at core board T1 moment is cached into second memory；GNSS receiver, which receives, comes from GNSS receiver core
The initial data at board T2 moment is cached into second memory；GNSS receiver, which receives, comes from GNSS receiver core board
The initial data at T3 moment is cached into second memory；The rest may be inferred, until GNSS receiver, which receives, comes from GNSS receiver
The initial data at core board Tn moment is cached into second memory 30, when completing the T1 to Tn in period first time as a result,
The caching of the data at quarter, wherein the time interval of each time cycle is 1.5 times of resolving period.
Step 3, when length reaches 1.5 times of resolving period at that time, microprocessor 10 will be stored in the second storage unit 30
The data at T1 to Tn moment be transferred in third storage unit 40.
Step 4, microprocessor 10 are sent out the data at T1 to the Tn moment in third storage unit 30 by communication unit 50
It sees off, is divided into two kinds of situations at this time.The first situation carries out second if the data at T1 to Tn moment are all successfully transmitted
The reception and transmission of the data at Tn+1 to the T2n moment of time cycle, the data at Tn+1 to the T2n moment of second time period
It receives and the reception of sending method and the data in period first time is identical as sending method, is i.e. the data of second time period are first
It is cached into the second storage unit 30, after reaching 1.5 times of resolving period, microprocessor 10 is by second time period
Data are transferred to third storage unit by the second storage unit 30, and data transmission is carried out in third storage unit 40, wherein
If there is network interruption and not sent data are retransmitted also unsuccessful, the then not sent data meeting of second time period
It is stored in third storage unit 40；Second situation, if cannot achieve data in Ti to Tn moment in Ti moment network interruption
Transmission, then enter step five；
Step 5, microprocessor 10 retransmit the data of Ti to Tn moment, retransmit three times, if the data at Ti to Tn moment are sent out
Success is sent, then carries out the reception and transmission of the data at Tn+1 to the T2n moment of second time period, the Tn+1 of second time period
The reception of reception and sending method and the data in period first time to the data at T2n moment is identical as sending method, as above
It is described；If the data transmission at Ti to Tn moment is unsuccessful, six are entered step, in successful Ti to Tn moment not sent at this time
Data be stored in third storage unit 40；
Step 6, microprocessor 10 continue to the Tn+ of the second time period of the transmission of GNSS receiver core board 100
The data at 1 to T2n moment, and the data at Tn+1 to T2n moment are stored into the second storage unit 30；When reaching 1.5 times
When resolving the period, the data at Tn+1 to the T2n moment being stored in the second storage unit 30 are transferred to third by microprocessor 10
In storage unit 40, the data of Ti to Tn and Tn+1 to T2n moment are stored in third storage unit 30 at this time；Microprocessor
10 retransmit the data in Ti to the Tn moment in third storage unit 40, are divided into two kinds of situations at this time.The first situation, if Ti is extremely
The not sent success of data in the Tn moment, then carry out third period of time T 2n+1 to the T3n moment data reception and transmission,
The reception of the reception of the data of third time cycle and sending method and the data in period first time is identical as sending method, i.e.,
The data of third time cycle are introduced into the second storage unit 30 and are cached, after reaching 1.5 times of resolving period, micro process
The data of third time cycle are transferred to third storage unit 40 by the second storage unit 30 by device 10, and in third storage unit
Data transmission is carried out in 40, wherein only when the not sent data of the data in period first time and second time period are sent out
After sending successfully, the transmission of the data of third time cycle just will do it；Second situation, if the data in Ti to Tn moment are sent
Success, then enter step seven；
Step 7, microprocessor 10 send Tn+1 to the T2n moment of the second time period in third storage unit 40
Data, wherein data sender's formula of second time period is identical as the sending method of the data in period first time, i.e., if
The data at Tn+1 to the T2n moment of second time period are all sent successfully, then carry out the reception of the data of third time cycle
With transmission, the reception and sending method of the reception of the data of third time cycle and sending method and the data in period first time
It is identical；If there is network interruption and not sent data are retransmitted also unsuccessful, then second time period is not sent
Data can be stored in third storage unit 40.
The foregoing is merely the data storage and management method of three time cycles, data storage management provided by the present invention
Method is not limited to three time cycles, and this method can be used for the data storage management of multiple time cycles, multiple time cycles
Data method and similarly to the above when carrying out storage management, the data of each time cycle are required to first cache to second
Storage unit, after reaching setting time, the data being stored in the second storage unit are transferred to third and stored by microprocessor
Unit, and sent in third storage unit.Wherein, only when data all in previous time period send success,
It will do it the transmission of latter time period data, such mode can prevent from losing number in data transmission procedure well.Furthermore
Data storage and management method of the invention provides a kind of mode of time-sharing work, avoids GNSS receiver core board well
Card 100 is constantly in working condition with communication unit 50, so as to reduce the power consumption of GNSS receiver.
