Description
Technical field
The invention belongs to nuclear power station control technology fields, and in particular to a kind of safety level multibus collaboration working method.
Background technology
Field bus control system is a kind of infant industry control system in recent years, be after DCS another more
Add superior open super distributed industrial control system.Fieldbus is for fields such as process automation, industrial automations
Field intelligent device interconnected communication establishes industry spot and control device and its management as the basis of industrial digital communication
Writing to each other between layer.Fieldbus just has more than 10 kinds there are many kinds of class applied to industry spot at present, such as CAN,
LONWORKS, PROFIBUS etc., these bus methods respectively have its advantage, data can reliable communication, but it is stringent in safety level DCS
Response time requirement under, cannot achieve multigroup bus and independently cooperate.
Invention content
The purpose of the present invention is to provide a kind of safety level multibus collaboration working method, it can either ensure that data are reliable,
It can ensure that bus cooperates again.
In order to achieve the above objectives, the technical solution used in the present invention is：
A kind of safety level multibus collaboration working method, controller A and controller B are connected to multigroup independent bus simultaneously
On, the cycle phase of every group of bus is same, and the node in every group of bus is all determined according to the sending time of last bag data in bus
Oneself occupy the time of bus, all buses are all first started by controller A and controller B simultaneously, and the node in all buses is all
The sending time that oneself is determined, occupies bus in a predetermined sequence, so repeats, and realizes that multibus cooperates.
This method is as follows：The first step：Controller A in all buses simultaneously transmission data；Second step：Packet
All nodes of all buses of the B containing controller receive the data of bus 1, and are calculated certainly according to the time for receiving this data packet
When oneself occupies the bus at respective place；Third walks：Controller B in all buses simultaneously transmission data；4th step：Including control
All nodes of all buses of device A processed receive the data of bus 1, and how calculate oneself according to the time for receiving this data packet
When respectively where occupancy bus；5th step：IO1 in all buses is stuck in the bus of oneself transmission data simultaneously；Including
All nodes of all buses of controller A and controller B receive the data of bus 1, and according to receive this data packet when
Between calculate when oneself occupies bus；7th step：IO2 in all buses is stuck in the bus of oneself transmission data simultaneously.
It is obtained by the present invention to have the beneficial effect that：
The present invention proposes a kind of safety level multibus working mechanism, meets the stringent response time requirements of safety level DCS, and
It can ensure that data are reliable, safe.
Specific implementation mode
With reference to specific embodiment, the present invention is described in detail.
Controller A and controller B is connected in multigroup independent bus simultaneously, and the cycle phase of every group of bus is same, and every group total
Node on line determines the time for oneself occupying bus all according to the sending time of last bag data in bus.All buses
All first being started simultaneously by controller and (sends the first bag data), the node in all buses all determines the sending time of oneself,
Bus is occupied in a predetermined sequence.It so repeats, is achieved that multibus cooperates.It is as follows：
The first step：Controller A in all buses simultaneously transmission data；
Second step：All nodes (contain controller B) of all buses receive the data of bus 1, and according to receiving this number
According to the time of packet, the bus for oneself when occupying respective place calculated；
Third walks：Controller B in all buses simultaneously transmission data；
4th step：All nodes (contain controller A) of all buses receive the data of bus 1, and according to receiving this number
According to the time of packet, the occupancy bus at oneself when respective place is calculated；
5th step：IO1 in all buses is stuck in the bus of oneself transmission data simultaneously；
6th step：All nodes (A containing controller, controller B) of all buses receive the data of bus 1, and according to connecing
The time for receiving this data packet, calculate when oneself occupies bus；
7th step：IO2 in all buses is stuck in the bus of oneself transmission data simultaneously.
Claims (2)
1. a kind of safety level multibus collaboration working method, it is characterised in that：Controller A and controller B is connected to multigroup simultaneously
In independent bus, the cycle phase of every group of bus is same, and the node in every group of bus is all according to the hair of last bag data in bus
The time is sent to determine that the time for oneself occupying bus, all buses are all first started by controller A and controller B simultaneously, all buses
On node the sending time of oneself is all determined, occupy bus in a predetermined sequence, so repeat, realize multibus collaboration
Work.
2. safety level multibus collaboration working method according to claim 1, it is characterised in that：The specific steps of this method
It is as follows：The first step：Controller A in all buses simultaneously transmission data；Second step：Include the institute of all buses of controller B
There is node to receive the data of bus 1, and calculates oneself when occupy the total of respective place according to the time for receiving this data packet
Line；Third walks：Controller B in all buses simultaneously transmission data；4th step：Including all buses of controller A is all
Node receives the data of bus 1, and the occupancy bus at oneself when respective place is calculated according to the time for receiving this data packet；
5th step：IO1 in all buses is stuck in the bus of oneself transmission data simultaneously；Including controller A's and controller B is all
All nodes of bus receive the data of bus 1, and calculate when oneself occupies bus according to the time for receiving this data packet；
7th step：IO2 in all buses is stuck in the bus of oneself transmission data simultaneously.
