Technical field
The present invention relates to field of communication technology, in particular to a kind of main equipment gives the method and system from device numbering.
Background technique
For Knitting Machinery or other systems, when the system has main equipment and when from equipment, when main equipment it is to be understood that
From the specific location of equipment, or when to being ranked up from equipment, artificial will record from the physical address of equipment and position is needed
Relationship reference numeral is set, and in the host by number information burning.Such mode is cumbersome, labor intensive, main equipment
Can not identiflication number automatically be carried out to from the spatial position of equipment.
Summary of the invention
The purpose of the present invention: providing a kind of main equipment to from equipment and system be numbered, and solves the existing cumbersome trouble of number
The problem of.
The solution that the present invention solves its technical problem is: a kind of main equipment is given from device numbering system, comprising: master sets
It is standby and several from equipment, each is mounted on positioning resistance from equipment, described to pass through data/address bus and master from equipment
Device talk connection, is serially connected and is formed resistance string from the positioning resistance in equipment, and the tail end of the resistance string connects over the ground,
The head end of the resistance string is connect with reference voltage, described to be used to acquire its corresponding positioning resistance place node and electricity from equipment
Voltage difference between resistance string tail end, it is poor that the voltage difference is denoted as positioning voltage, and the positioning voltage difference is passed through data/address bus
Pass to main equipment；The main equipment to each from equipment for being numbered in order according to the size of positioning voltage difference.
Further, described to be equipped with AD acquisition interface from equipment, the AD acquisition interface with from the corresponding positioning resistance of equipment
One end connection.
Further, head end of the one end of the positioning resistance close to resistance string.
Further, the resistance value of each positioning resistance from equipment is equal.
Further, the data/address bus includes: CAN bus, 485 buses, iic bus, serial bus any one.
The beneficial effects of the present invention are: this system creativeness is empty to carrying out from the spatial position of equipment using positioning resistance
Between on mark, and by positioning voltage difference between comparison so that main equipment can be identified automatically from equipment
Spatial position facilitates main equipment to the identiflication number from device space position.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is the system block diagram of this system.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, Lai Zucheng more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
With reference to Fig. 1, a kind of main equipment is given from device numbering system, comprising: main equipment and N number of from equipment, be denoted as respectively from
Equipment 1, from equipment 2 ..., from equipment N, wherein N >=2, each is mounted on positioning resistance R from equipment, logical from equipment
Cross data/address bus and main equipment communication connection.Wherein, 485 buses, CAN bus, iic bus or serial ports can be passed through from equipment
Bus and main equipment communication connection.It is serially connected to form resistance string 100 from the positioning resistance R in equipment, wherein resistance string 100
Head end connect reference voltage VCC, the GND connection over the ground of the tail end of resistance string 100.In some embodiments, resistance string 100
Tail end may be at main equipment side, and the head end of resistance string 100 may be at from equipment side.In some embodiments, positioning electricity
Resistance R is also possible to the resistance pair being made of single or multiple resistance.Each is equipped with AD acquisition interface from equipment, passes through AD
Acquisition interface can convert analog signals into digital signal, the convenient communication between equipment and main equipment.AD acquisition interface
It is connect with the left end of positioning resistance R, head end of the left end for positioning resistance R close to resistance string 100.When the system is operating, from
Equipment acquires the voltage difference of its corresponding positioning resistance R, and it is poor that the voltage difference is denoted as positioning voltage, in the present embodiment, from setting
Standby 1, from equipment 2 ..., be not denoted as from the positioning voltage difference of equipment N: V1, V2 ..., VN, however, be evident that, V1 > V2 > ... >
VN, from equipment 1, from equipment 2 ..., from equipment N respectively by its corresponding positioning voltage difference by data/address bus pass to master set
Standby, main equipment can be numbered in sequence according to the positioning voltage difference received, and the present embodiment is using according to from big
It is arranged to small sequence, i.e., is 1 from the number of equipment 1, the number from equipment 2 is 2, and so on, from the number of equipment N
For n, by this number with from the corresponding physical address binding of equipment, in this way it is known that from equipment and between equipment
Positional relationship spatially.
This system creativeness carries out mark spatially to from the spatial position of equipment using positioning resistance R, and passes through
Comparison between positioning voltage difference facilitates master to set so that main equipment can automatically be identified from the spatial position of equipment
For to the identiflication number from device space position, facilitate later period main equipment to the scheduling from equipment.
As optimization, the resistance value of each positioning resistance R from equipment is equal.By the way that resistance is arranged from equipment each
It is worth opposite positioning resistance R, can be convenient the replacement from equipment, convenient for the maintenance in later period.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
