Abstract
The invention discloses a feed type bus method, and belongs to the technical field of electronic communication, for the purpose of providing a feed type onsite bus method which has the advantages of reducing onsite construction wiring requirements and improving product anti-interference performance. The bus method comprises a front portion, an inspection portion and an end bit portion. The three portions specifically comprise the following steps: A, the front portion is 24V high level with an instruction interval not smaller than 3ms wide; B, the inspection portion comprises an address instruction, a command instruction, an operand instruction and a BCC instruction, wherein the address instruction is an 8-bit address plus 1-bit verification, the command instruction is an 8-bit command plus 1-bit verification, the operand instruction is an 8-bit operand plus 1-bit verification, and the BCC instruction is an 8-bit BCC plus 1-bit verification; and C, after the inspection portion is sent, high level greater than 600[mu]s is taken as an end bit.
Description
Technical field
The present invention relates to a kind of bus method, particularly a kind of feeding type bus method.
Background technology
In prior art, the most narrow spaces of field bus technique is 50 μ s, is highly prone to on-the-spot interference signal disturbing, causes controller or headend equipment erroneous judgement.On-the-spot headend equipment is patrolled and examined the mode adopting question-response by prior art.Send out one and patrol and examine order, a headend equipment can only be patrolled and examined.During for there being multiple on-the-spot headend equipment to patrol and examine, on-the-spot headend equipment response can be caused not prompt enough.
Summary of the invention
It is an object of the invention to be in that to solve existing loop bus transmitting-receiving code sequential, General Promotion fieldbus capacity of resisting disturbance, returned by global command, simple pulsewidth, be used for improving controller to on-the-spot headend equipment response speed.And a kind of feeding type bus method is provided.
A kind of feeding type fieldbus method, it is characterised in that: described bus method includes preceding sections, patrols and examines part and stop bits part, and concrete described above-mentioned three parts comprise the following steps:
A, preceding sections are level 24V, and command interval is not less than the high level that 3ms is wide；
B, patrol and examine part include address instruction, command instruction, operand instruction and BCC instruction, described address instruction is that 8bit address adds 1bit effect；Described command instruction is that 8bit order adds 1bit effect；Described operand instruction is 8bit operand and 1bit effect；Described BCC instruction is that 8bitBCC adds 1bit effect；
C, after having sent and having patrolled and examined part, with the high level more than 600us as stop bits.
Technique scheme is adopted to provide the benefit that:
1, position pulsewidth is by original most narrow spaces, 50 μ s rise to 200 μ s.Reduce on-the-spot headend equipment to time order error requirement.Reduce site operation cabling requirement, increase the jamproof performance of product.
2, patrolling and examining technology by synchronization, increase field devices respond speed, originally field apparatus is adopted question-response mode by bussing technique.The 4 second time of need has been asked from asking tail to the end.Synchronization is adopted to patrol and examine technology, it is possible to response speed was controlled within 1 second.
Detailed description of the invention
The following is currently preferred specific embodiment present disclosure is further described.Example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
A kind of feeding type fieldbus method described in this programme, described bus method includes preceding sections, patrols and examines part and stop bits part, and concrete described above-mentioned three parts comprise the following steps:
A, preceding sections are level 24V, and command interval is not less than the high level that 3ms is wide；
B, patrol and examine part include address instruction, command instruction, operand instruction and BCC instruction, described address instruction is that 8bit address adds 1bit effect；Described command instruction is that 8bit order adds 1bit effect；Described operand instruction is 8bit operand and 1bit effect；Described BCC instruction is that 8bitBCC adds 1bit effect；
C, after having sent and having patrolled and examined part, with the high level more than 600us as stop bits.
In this programme, described BCC verification is the BCC exclusive or check result of all bytes comprising address instruction, command instruction and operand instruction, and 1bit check bit is the parity check bit of every byte, adopts odd；Described address instruction is the transmission of bus binary system, 8 bit address and 1 odd parity bit, totally 9, this location scope 1～254us, broadcast address 0；Command instruction bus binary system described in this programme sends, 8 order of the bit and 1 odd parity bit totally 9；Operand instruction described in this programme is that bus binary system sends, and operand frame is 8 bit data and 1 odd parity bit totally 9 (the operand frame difference according to order, byte number from 0 to n byte)；In this programme, above address instruction, command instruction, operand instruction are only sent out once, and address instruction, command instruction and operand instruction are all continuously every transmission.Bus apparatus, when receiving address instruction, command instruction or operand instruction, by detecting the width of height pulse, judges that this position is " 1 " or " 0 " or stop bits.Decoding receive pulsewidth fault-tolerant ± 25%.In this programme, " 0 " is first to send 200us low level to retransmit 400us high level；Described " 1 " is first to send 400us low level, retransmits 200us high level.In this programme, when restrainting bit position when performing to finish, frame format starts to return operation, and described return operation is divided into two kinds of situations, and one is without return, and another is that simple pulsewidth returns and byte number returns.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
