Description
Technical field
The present invention relates to intelligent electric meter technical field more particularly to the means of communication of a kind of electric energy meter and communication module.
Background technique
With the promotion of electric energy meter technology, the requirement for human-computer interaction is higher and higher, wherein the communication part of most critical
Seem especially prominent, communication module needs are communicated with the master controller in electric energy meter, and can when the communication of existing electric energy meter
With the communication module of use, there are many type, communications protocol, there are many types, but a kind of communication module is generally only capable of using one
Kind communications protocol is communicated with master controller, therefore different communication module and master controller is caused to need change to lead when communicating
Control program in controller, or while being updated to original communications protocol, are also required to the control journey in change master controller
Sequence, and the control program for changing master controller then needs reheating to enter code just to be achieved, the process complexity is cumbersome, is modified to
This is higher, therefore the communication of existing electric energy meter, communication module is poor, and suitability between the two is poor.
Summary of the invention
The present invention provides the means of communication of a kind of electric energy meter and communication module, the electric energy meter in this method can match more
The different types of communication module of kind, a variety of different types of communications protocol mention so that electric energy meter, communication module is general higher
High suitability therebetween.
The technical scheme adopted by the invention is that the means of communication of a kind of electric energy meter and communication module, comprising the following steps:
S1, beginning are built-in with type information collection, the communication module communications protocol collection of communication module in electric energy meter；It is described
Electric energy meter to communication module send read data command, the reading data command using general data frame format transmission；
Type information, the communications protocol of communication module are built-in in S2, the communication module；If communication module is not replied
Data command is read, then enters S7；If data command is read in communication module response, enter in next step, the communication module
Reading data command described in response uses the response of general data frame format；
After S3, electric energy meter receive the reply data of communication module, the general data frame of communication module response is first determined whether
Whether format is legal；If the general data frame format of response is illegal, enter S7；If the general data frame format of response is closed
Method then enters in next step；
S4, electric energy meter continue to judge whether the type of communication module is legal；If the type of communication module is illegal, enter
S7；If the type of communication module is legal, enter in next step；
S5, electric energy meter finally judge whether the communications protocol of communication module is legal, if communications protocol is illegal, enters
S7；If communications protocol is legal, enter in next step；
S6, communication module and electric energy meter match, into S8；
S7, communication module and electric energy meter mismatch, and electric energy meter alarms and records abnormal data, into next step；
S8, end.
After the above technical solution is adopted, compared with the prior art, the present invention has the following advantages:
Type information collection, communication module communications protocol collection of the present invention by communication module built-in in electric energy meter, so that
Electric energy meter can match a variety of different types of communication modules, a variety of different communications protocol, lead to for different clients are different
News module, communications protocol can be applicable in, and without configuring again to master controller in electric energy meter, reduce electric energy meter
Production cost, while also substantially increasing the suitability between communication module and electric energy meter, versatility.
As an improvement, the method that data command is read in the communication module response are as follows: the first step starts, communication module
Receive reading data command transmitted by electric energy meter；Second step judges the general data for reading data command and sending
Whether frame format and the general data frame format that it is used for response are identical, if they are the same, then reply the type and agreement of communication module
Version is to electric energy meter；If not identical, terminate, prejudging electric energy meter and general data frame format used in communication module is
It is no consistent, directly terminate to communicate when inconsistent, facilitates reduction electric energy meter and judge the communication module whether matched time.
As an improvement, the general data frame format is, frame head+control word+length+data+verification+postamble is described
Data in include communication module type and communications protocol, general data frame format is relatively simple.
As an improvement, reading the general data frame format that data command is sent described in judgement is used for response with communication module
The whether identical mode of general data frame format be that will read frame included in general data frame transmitted by data command
Frame head, control word, verification included in the general data frame of head, control word, verification and postamble and communication module for response
Identification judgement is carried out correspondingly respectively with postamble, accuracy of judgement, precisely.
As an improvement, the verification uses Crc16 check addition, it is accurate to examine.
As an improvement, the type of the communication module includes RF, SP300, PRIME, G3,2G, 3G, 4G, 5G, NB-
LOT, ZIGBEE, BLUETOOTH, M-bus, MODBUS, 485, reserved communication module, the type of every kind of communication module are corresponding a kind of
The type information of communication module, type is more, covers the type of conventional communication module, while being equipped with reserved communication module, has
Scalability, avoiding the occurrence of new communication module can not be adapted to electric energy meter, use convenient for selecting.
As an improvement, the communication module type information concentrate include RF, SP300, PRIME, G3,2G, 3G, 4G,
5G, NB-LOT, ZIGBEE, BLUETOOTH, M-bus, MODBUS, 485, the class of communication module corresponding to reserved communication module
Type information, covering scope are wide.
As an improvement, it includes reserved communications protocol that the communication module communications protocol, which is concentrated, there is scalability, avoid
New agreement electric energy meter and communication module occur can not normal communication.
