Description
Technical field
Present invention relates particularly to a kind of date storage methods of intellectual water meter.
Background technique
With the development and the improvement of people's living standards of national economy technology, intelligence instrument has been widely used for people
Daily life in, play very important effect.
Intellectual water meter as the metering unit in water system, the importance of continuous data, operational data etc. do not say and
Analogy.Intellectual water meter data storage is a very important function, it saves the data on flows of water meter, recharge amount, consumption
The important parameters information such as information, communication, and require for significant data information to be unanimously saved in several years more than water meter service life
Time clears matters so as to later period water meter operation and maintenance and with client；Intellectual water meter saves the general holding time of data at present
It is 8 years, data save once daily.In order to reliably and with long-term, the data of safety assurance intellectual water meter storage, make its data be not easy to lose
Mistake is lost or occurred, is that data preservation is carried out using separate storage chip using general approach.This scheme has following defects that
It is at high cost, utilization rate is low；Circuit design is relative complex, and the EMC performance of separate storage chip is low, and data transmission anti-interference is poor,
Need to increase complicated protection device；Easily stolen to take or destroy, separate storage chip does not support secrecy provision generally, and operates association
View is standard public information, can steal and modify the data in memory by extraneous means, and the management such as water supply company is caused to look forward to
The loss of industry；SAM Stand Alone Memory capacity is directly proportional to cost, carries out data exception protection without spare capacity.If encountering data
Storage is abnormal, and not only when secondary data can not save, the data of Historic preservation, which also go to pot, to be restored.
Summary of the invention
The purpose of the present invention is to provide a kind of data of the quick reliable and low-cost intellectual water meter of data storage
Storage method.
The date storage method of this intellectual water meter provided by the invention, the flash carried using Intelligent water meter controller
Area carries out the storage of data, and storage method includes the following steps:
S1. when needing to carry out data storage, the memory block flash for needing data to be saved and inquiring controller is obtained
The information content of interior all memory pages；
S2. judge the state of all memory pages in the memory block flash:
If all memory pages are the blank section page not operated, the number that currently will need to store in the memory block flash
Enter first memory page according to saving with storage time；
If all memory pages are non-empty white area and the memory page there are blank in the memory block flash, when time water is believed
Breath and storage time are stored in corresponding memory page；
If all memory pages are non-empty white area in the memory block flash, storage time and intelligence in all memory pages are inquired
Can water meter runing time closest to which memory page；
S3. the position for the memory page that judgment step S2 is obtained:
If the memory page is not located at the end of the blank area, water data information and storage time are stored in this memory page
Next page number memory block in；
If the memory page is located at the end of the blank area, water data information and storage time are stored in this memory page
In homepage memory block.
The date storage method of the intellectual water meter, further includes following steps:
S4. step S1 ~ S3 is repeated, until the data of institute's some need storage all complete by storage, that is, completes intelligent water
The data of table store.
Described in step S2 then ought time water amount information and storage time be stored in corresponding memory page, specially will be by page
Sequence is when in time water amount information and the corresponding memory page of storage time deposit number from small to large.
The date storage method of this intellectual water meter provided by the invention is carried out due to not using additional storage chip
The storage of data, therefore cost is reduced, and simplify circuit design；Further, since the area flash of controller is all read protection
Configuration, therefore storage information can not be stolen by extraneous means, so that the data information of metering water meter is more safe and reliable；Most
Afterwards, since the every page preservation data information project in the region flash of controller is the same, even if when time data storage generation is different
Often, historical data will not be destroyed easily, can give historical data reduction damage for change by reading last memory page data information
It loses.Date storage method of the invention, it is applied widely, it is applicable not only to intellectual water meter, is also applied for can be used for all types of
Intelligent metering instrument, such as intelligent electric energy meter, intelligent gas meter, intelligent calorimeter etc., it can also be used to which other any need utilize
The electronic equipment of flash pages of progress data storage of controller, including electric energy management terminal, distribution terminal, electric energy quality monitoring
Equipment, grid automation terminal, acquisition terminal, concentrator, data collector, measuring instrument write by hand device etc..
Detailed description of the invention
Fig. 1 is the flow chart of the method for the present invention.
Specific embodiment
It is as shown in Figure 1 the flow chart of the method for the present invention: the date storage method of this intellectual water meter provided by the invention,
The storage of data is carried out using the area flash that Intelligent water meter controller carries, and storage method includes the following steps:
S1. when needing to carry out data storage, the memory block flash for needing data to be saved and inquiring controller is obtained
The information content of interior all memory pages；
S2. judge the state of all memory pages in the memory block flash:
If all memory pages are the blank section page not operated, the number that currently will need to store in the memory block flash
Enter first memory page according to saving with storage time；
If in the memory block flash all memory pages be non-empty white area and the memory page there are blank, by page number from it is small to
Big sequence is when in time water amount information and the corresponding memory page of storage time deposit；
If all memory pages are non-empty white area in the memory block flash, storage time and intelligence in all memory pages are inquired
Can water meter runing time closest to which memory page；
S3. the position for the memory page that judgment step S2 is obtained:
