Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Existing single-phase electric energy meter or three-phase electric energy meter, although being all designed with multiple communication ports, field application
When, it is general only to be used there are one communication port.Such as module table, substantially carried out data transmission using module, and 485 tables are only
Carried out data transmission using 485 mouthfuls.Certainly the case where it is mixed to be also not excluded for live phenotype, is communicated for 485 mouthfuls such as module table.By
Even if often data can be obtained from electric energy meter if communication module communicates it without acquisition terminal itself, at this moment to electric energy
For table, it is possible to be related to 2 communication channel simultaneous communications.Therefore, for electric energy meter common communication channel its
At most also with regard to 2.
Currently, it is 512 bytes that electric energy meter 698, which communicates maximum transmission or receiving frame, and maximum can handle APDU
(ApplicationProtocolDataUnit, Application Protocol Data Unit) is 2Kbyte, and therefore, a channel needs slow
It is 2Kbyte to deposit size.If the method for distributing a block RAM using each channel, three-phase electric energy meter has 4 channels, then needs
8Kbyte, single-phase meter have 3 channels, then need 6Kbyte.This RAM demands are typically of 32Kbyte relative to electric energy meter
RAM resources or 8Kbyte RAM resources for, the ratio of occupancy is great.
In addition, operated every time when electric energy meter communicates (read, be arranged etc.) when, APDU data, which can't reach maximum, to be located
The data volume of APDU is managed, it is therefore considered that one piece of distribution is not form of the prodigious RAM cachings as dynamic allocation, is supplied
Each channel uses, and arrives first and first obtains, is finished and releases immediately.
When maintaining communication caching expense under normal circumstances, it is occupied to will appear dynamic ram once in a while using dynamic ram
It is finished, but there is the case where communication generates (such as site infrare copy reading data) in other channels again.In order to ensure to communicate in this case
Normally, it is necessary to start spare buffering scheme, and nonvolatile memory (such as EEPROM may be used in spare caching
(Electrically Erasable Programmable read only memory, Electrically Erasable Programmable Read-Only Memory),
FLASH (flash memory) etc.).Since spare caching applying frequency is relatively low, as long as reserved small part resource meets requirements for life.
Based on the above reasons, a kind of electric energy meter communication data storage method, device and electric energy provided in an embodiment of the present invention
Table can carry out the distribution of dynamic ram space, can meet normal communication requirement using RAM resources few as possible.
The embodiment of the present invention is described in detail below.
An embodiment of the present invention provides a kind of electric energy meter communication data storage method, electric energy meter shown in Figure 1 communications
The flow diagram of date storage method, this method comprises the following steps：
Step S102, during initial configuration, for communication data distribution shared dynamic memory and slack storage.
Wherein, it is dynamically stored as random access memory ram, slack storage is nonvolatile memory.Since RAM can be at any time
Read-write, and speed is quickly, may be used as the common storage of memory communicating data；Nonvolatile memory, which has to smear, writes cycle
Number limits, and may be used as the slack storage of memory communicating data, frequency of use is relatively low, and excessive memory space need not be arranged
Life requirements can be met.
Different from the mode that one piece of individual RAM carries out communication data storage is arranged for each communication channel of electric energy meter,
Method provided in this embodiment is that a shared dynamic memory RAM is arranged in the communication data of all channels transmitting-receiving, using arriving first
First mode communication data is stored to dynamic memory RAM when there is communication data transmitting-receiving in some channel, when dynamically depositing
After the space storage completely for storing up RAM, then spare nonvolatile memory is used.
In view of the limited memory space of electric energy meter, the space size for rationally determining dynamic memory and slack storage is needed,
Normal use should be met, reduce caching expense again.For example, can carry out as follows：
(1) communications protocol supported according to electric energy meter determines that the maximum of single communication channel can handle APDU.The maximum can
Handle the maximum memory space that APDU, that is, single communication channel needs.
(2) size that APDU determines dynamic memory and slack storage can be handled according to maximum, and distributes shared dynamic and deposits
Storage and slack storage.
It, can be by the big of dynamic memory by taking electric energy meter commonly uses a communication channel or two communication channel transceiving datas as an example
The size of the small size for being set as APDU or twice of APDU, may be set to be arbitrary value between the two, need to note herein
Meaning is the demand that cannot be less than a communication channel.Such as support the electric energy meter of 698.45 communications protocol of link layer DL/T,
Maximum is sent or receiving frame is 512 bytes, and it is 2Kbyte that maximum, which can handle APDU, and therefore, a communication channel needs to cache big
Small is 2Kbyte.If the electric energy meter commonly uses a communication channel, less two communication channels are few using more than two logical
It interrogates channel (such as most four communication channels), then dynamic memory can be set to 2Kbyte or 4Kbyte, by slack storage
It is set as 6Kbyte or 4Kbyte.The calculation of the wherein minimum space of slack storage is：Overall channel number * APDU- dynamics are deposited
Size is stored up, the upper example of act is connect, then obtains that slack storage is 6Kbyte or 4*2Kbyte-4Kbyte obtains for 4*2Kbyte-2Kbyte
It is 4Kbyte to slack storage.
Step S104 carrys out memory communicating data when receiving and dispatching communication data using dynamic memory.
When electric energy meter receives and dispatches communication data, first carrys out memory communicating data using dynamic memory, communication speed can be improved.
After dynamic memory is filled with, then carry out memory communicating data using slack storage.It should be noted that using dynamic memory
It after the storage for carrying out communication data, needs in time to use dynamic memory, dynamic memory is shared to meet each communication channel
Purpose.
Step S106 carrys out memory communicating data after dynamic memory is filled with using slack storage.
Electric energy meter communication data storage method provided in an embodiment of the present invention, for the big electric energy meter of data volume, for communication
Data distribution shared dynamic memory and slack storage, wherein being dynamically stored as random access memory ram, slack storage is non-volatile
Property memory；When electric energy meter receives and dispatches communication data, first carry out memory communicating data using dynamic memory, after dynamic memory is filled with,
Carry out memory communicating data using slack storage, the distribution of dynamic ram space can be carried out, use RAM resources few as possible can expire
Sufficient normal communication requirement, to effectively reduce the cost of electric energy meter.
Stored to above-mentioned shared dynamic memory or slack storage in communication data, further include release storage process from
And sharing for storage is completed, the above method is further comprising the steps of：After communication data is read, release dynamics storage and/
Or slack storage.The communication data stored in above-mentioned dynamic memory or slack storage is then stored after reading
Release, for other communication datas use.
To receiving the process of communication data, it is contemplated that the space for effectively using dynamic memory can apply using several times
Dynamic memory, each dynamic memory for applying for predetermined threshold value size, above-mentioned the step of carrying out memory communicating data using dynamic memory,
Including：
(1) when receiving communication data, apply for the dynamic memory of predetermined threshold value size and store the communication data.This is default
Threshold value can be determined according to the characteristics of communication data itself.Such as communication data uses link layer framing, then according to framing
Size determine the predetermined threshold value, predetermined threshold value is equal to the size of the framing, i.e., for the first time apply when can apply
In the dynamic memory of the framing, and gradually application is equal to the dynamic memory of the framing, so as to efficiently use dynamic memory, to the greatest extent
Amount generates invalid share storage and occupies less.
(2) if the incomplete memory communicating data of the dynamic memory of predetermined threshold value size, apply for predetermined threshold value size again
Dynamic memory stored, until complete memory communicating data.
When receiving data, stored memory is needed by block application, until complete storage.
Due to it is above-mentioned press block application dynamic memory in the case of, there are the feelings that the memory space finally applied does not take
Condition, thus the above-mentioned application dynamic memory the step of before, it is also necessary to judge currently with the presence or absence of the memory space not utilized, on
It is further comprising the steps of to state method：
(1) judge currently with the presence or absence of having applied and not used dynamic memory.
(2) if so, storing communication data to having applied and not used dynamic memory.If it is not, then applying again
The dynamic memory of predetermined threshold value size.
Process to sending communication data then can be according to the size one due to the size of the known data for needing to send
The space of secondary property application dynamic memory, above-mentioned the step of carrying out memory communicating data using dynamic memory, including：Number is communicated when sending
According to when, the space size of dynamic memory for needing to apply is determined according to the size of the communication data；According to the space size application
Dynamic memory, and memory communicating data.
In view of sharing dynamic memory, communication data is stored to when dynamic memory and is not continuous, when being stored
It needs to record its position stored, therefore the above method may be used also after the step of being carried out memory communicating data using dynamic memory
To include the following steps：Record the storage total length of data and the corresponding location information of dynamic memory in dynamic memory.
Wherein, location information can be recorded by way of storing message queue.At the time of reading, it needs to be deposited according to this
Message queue is stored up, the storage location for the data that continue is found, then block-by-block is read since the position found again, until reading needs
Data volume until.
Electric energy meter communication data storage method provided in an embodiment of the present invention is done the common caching of data using dynamic ram, is used
Nonvolatile memory does spare caching, can apply using dynamic memory when receiving data several times, application is default every time
The dynamic memory of threshold size can disposably apply for dynamic memory according to the size of transmission data when sending data, to
A small amount of RAM resources can be used up, normal communication requirement is met, reducing cost to electric energy meter probably plays great role.
An embodiment of the present invention provides a kind of electric energy meter communication data storage methods, are applied to the link layer framing of electric energy meter
The storage of data.There are two types of situations for the link layer framing used in 698.45 communications protocol of DL/T：The framing of receives link layer and hair
Send link layer framing.When reception dynamic memory memory needs one piece of one piece of application, can transmission data as needed when transmission
Length is disposably applied.
The flow diagram of electric energy meter communication data storage method shown in Figure 2, communication data are individually located by channel
Reason, for receiving communication data, this method comprises the following steps：
Step S202 is judged whether there is and has been distributed and unused dynamic ram space.If so, executing step S204；If
It is no, execute step S206.
When needing to preserve the APDU segments for receiving framing, first judge whether there is what last stored did not used completely in the process
Dynamic ram space, if there is then first being stored using the unused memory space.
Step S204 judges whether to use enough.If so, executing step S208；If not, executing step S210.
In the case of enough, then the communication data of reception is stored to the space；In the case of not enough, then need
Apply for that new RAM memory spaces, application process may refer to above-described embodiment, details are not described herein.It should be noted that receiving
During applying for memory space, when applying for dynamic ram, since specific how many data below do not known, and a frame is received most
Long length is 512byte, and in order to reduce the use of waste RAM, the memory of 512byte is all only applied in application every time.
Step S206 applies for RAM memory spaces.
In have no alternative but to distribution and unused dynamic ram space, then apply for RAM memory spaces again.
Step S208 preserves the total length in data and change storage information.
If having distributed and unused dynamic ram space storing the communication data of reception enough, directly preserved, and
Change storage information in total length, the total length indicate the dynamic ram store data inside number.
Step S210 preserves a part of data to the unused dynamic ram space, until the space is filled up.
If having distributed and unused dynamic ram insufficient space enough storing the communication data of reception, preferentially this is used not
Dynamic ram space to the space is filled up, then applies for that new RAM memory spaces are preserved.
Step S212 applies for RAM memory spaces.
Step S214 preserves remainder data and change storage information.
Due to above-mentioned storage mode, these storage data are not continuous, but piecemeal, even in distinct device
Storage, it is therefore desirable to record the position of its storage.After preserving data every time, it is required for change management information, applies for space
It needs to increase a storage message queue data and changes storage total length of data, do not apply for that space only needs change storage data
Total length.
It when reading data, can not simply be obtained, be needed according to above-mentioned storage according to initial address and data length
The storage location for the data that continue is found in message queue, and then block-by-block is read since the position found again, until reading needs
Until data volume.
Step S216 preserves data and change storage information.
Relative to framing is received in the above method, as long as sending the length application storage of framing data to be sent as needed
Space carries out data preservation and change storage information.
Electric energy meter communication data storage method provided in an embodiment of the present invention is done the common caching of data using dynamic ram, is used
Nonvolatile memory does spare caching, when receiving data first using having distributed and unused dynamic ram space, then several times
Application uses dynamic memory, can use up a small amount of RAM resources, meet normal communication requirement, reducing cost very to electric energy meter has
Great role may be played.
In the above-mentioned methods, it either receives to preserve or send and preserve, wherein can all be related to applying for memory space
Operation.Since dynamic memory ram space is limited, dynamic ram is arrived in surely application of applying differing when memory space, at this moment applies
Memory space will be the memory space of nonvolatile memory.The method of electric energy meter application memory space shown in Figure 3
Flow diagram, this method comprises the following steps：
Step S302, application dynamic ram space, and judge whether to apply successfully.If so, executing step S304；If
It is no, execute step S306.
Since dynamic ram is shared dynamic memory, in multichannel simultaneously by data transmission when, then can lead to dynamic ram
It has been be otherwise fully engaged that, when applying for dynamic ram space, what is applied is the memory space of non-volatile memories.
Step S304 returns to RAM identification names.
Step S306 returns to non-volatile memories identification name.
Step S308 changes storage information according to above-mentioned identification name.
It in the case where storing to different memory spaces, needs to record corresponding storage location information respectively, for reading
