Abstract
The invention discloses a kind of methods of automobile-used lithium ion battery case automatic numbering, including a number host, at least two have the battery case and RS-485 bus of slave, it is characterized in that, being connected separately with signal transmitting apparatus in order between the number host and the slave of the first battery case and between the slave of remaining battery case；When the slave of battery case, which needs to distribute address, to be numbered, the number host sends the first address to the first slave by signal transmitting apparatus, the slave of first battery case, which receives, to be first address by the address configuration of oneself behind the first address and stores, then+1 on first address after the slave of next battery case is sent to by the signal transmitting apparatus between battery case slave, and so on until being assigned to the slave for being left all battery cases.The present invention can quickly distribute slave addresses, and the slave addresses and physical connection distributed have fixed corresponding relationship.
Description
Technical field
The present invention relates to a kind of methods of automobile-used lithium ion battery case automatic numbering.
Background technique
In Modbus RTU bus protocol based on RS-485 bus, there are a host and several slaves, Mei Gecong
Machine needs to distribute a different address, and method of the standard agreement the inside without distributing slave addresses automatically is general using manual
The mode of distribution.The mode of random slot scanning is usually used by the way of distributing automatically in some products.If it is base
In the system of CAN, LIN framework, multiple identical nodes link together, and can distribute address automatically, but can not distinguish each
A node.
When using the method for manual allocation slave addresses, need through additional hardware come setting address, Huo Zhedan
It solely configures just be linked into system behind address by host computer and use；When using random slot scanning distribution slave addresses
Method: time-consuming, and the ten or twenty second may be needed when especially slave quantity is more；The address of distribution be it is random,
It is required that slave and address have the occasion of clear corresponding relationship that cannot use；When use the system based on CAN, LIN framework, by
It is identical in each battery case, it is therefore necessary to address is distributed to CAN, LIN node of each battery case in advance, it in this way could be in master
Differentiate which battery case is data be from machine.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a kind of automobile-used lithium ion battery case automatic numberings
Method.
The present invention is achieved through the following technical solutions: a kind of method of automobile-used lithium ion battery case automatic numbering, including
One number host, at least two have slave battery cases and RS-485 bus, which is characterized in that the number host with
It is connected separately with signal transmitting apparatus in order between the slave of first battery case and between the slave of remaining battery case；When
The slave of battery case needs to distribute address when being numbered, the number host by signal transmitting apparatus send the first address to
First slave, the slave of the first battery case, which receives, to be first address by the address configuration of oneself behind the first address and stores,
Then+1 on first address after next battery case is sent to by the signal transmitting apparatus between battery case slave
Slave, and so on until be assigned to the slave for being left all battery cases.
Preferably, two signal transmitting apparatus are included at least
Preferably, the signal transmitting apparatus between the number host and the slave of the first battery case is asynchronous receiving-transmitting transmission
Device or differential signal line.
Signal transmitting apparatus between the slave of the preferably described battery case is asynchronous receiving-transmitting transmitter or differential signal line.
The invention has the following beneficial effects: its functionally can fast automatic distribution slave addresses, automatic distribution from
Machine address and address and the order of connection have specific corresponding relationship.Its signal wire for only needing to increase automatic distribution address in structure
Fast automatic distribution slave addresses can be realized.And the automatic distribution address does not need the stochastic backlash as other schemes and visits
It asks, the time of automatic distribution address is greatly saved.
Detailed description of the invention
It, below will be to required in embodiment or description of the prior art in order to illustrate more clearly of technical solution of the present invention
The attached drawing used is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Its attached drawing.
Fig. 1 is schematic diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, carries out to the technical solution in inventive embodiments clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
Reference book attached drawing 1, a kind of method of automobile-used lithium ion battery case automatic numbering, including a number host,
Multiple battery case (each battery case has a slave, and multiple battery cases have multiple slaves) He Lianggen RS- with slave
One of port of 485 buses, that is, RS-485A and RS-485B, the host and the multiple slave connects total in RS-485A
On line, another port is connect in RS-485B bus.As shown in Figure of description 1, in the number host and the first battery case
Slave between and the slave of remaining battery case between signal wire is also respectively connected in order；When the slave of battery case needs
When distributing address and being numbered, the number host sends the first address to the first slave by signal transmitting apparatus, and first
The slave of battery case, which receives, to be first address by the address configuration of oneself behind the first address and stores, then described first
The slave of next battery case is sent to after+1 on address by the signal transmitting apparatus between battery case slave, and so on it is straight
To being assigned to the slave for being left all battery cases.
Increased signal wire is segmentation, is not bus-type.In the application that baud rate is relatively low, transmission range is closer
Occasion, increased signal wire can send signal using UART (asynchronous receiving-transmitting transmitter), baud rate is relatively high, transmission range
Distant occasion can emit signal using two differential signal lines.
Host is placed on bus one end, slave is sequentially connected, then slave addresses are followed successively by 1,2,3,4 ....If
The position of slave is adjusted, slave addresses can distribute automatically again, be still to be followed successively by 1,2,3,4 ... in the order of connection thus automatic
Distribution address does not need the stochastic backlash as other schemes and accesses, and the time of automatic distribution address is greatly saved.
The preferred embodiment of the present invention has shown and described in above description, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, should not be regarded as an exclusion of other examples, and can be used for various other combinations, modification and
Environment, and can be changed within that scope of the inventive concept describe herein by the above teachings or related fields of technology or knowledge
It is dynamic.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be appended by the present invention
In scope of protection of the claims.
