Abstract
The utility model provides a novel distributed control system structure. The whole system it that a bus links each distributed control unit, and all control units are equipped with a microcomputer chip, a program memorizer, a data memorizer, a nonvolatile memory, a bus interface, a redundant and mutual-backup data exchange interface and various input and output interfaces. Because all units adopt the computer chips, all units can independently finish a control configuration program, which is programmed by the system engineer, thus the operations of the control program and the data disposals are all dispersed into each unit, and the thorough dispersion of failure danger is realized. The structure is characterized in that the whole system does not have the hidden trouble that a partial failure influences the overall situation, which ensures the safe operations of the industrial production devices.
Description
Technical field
The utility model belongs to a kind of new dcs (also being Distributed Control System (DCS) or the scattered control system) structure of automatic field, particularly a kind of new dcs structure.
Background technology
The structure of now domestic and international dcs, all input class unit, all the data that receive are delivered to a core cell (the title difference of each producer, but can be referred to as CPU (central processing unit)), this core cell is delivered to the output class unit to result or state after calculating again.The work of CPU (central processing unit) is to finish most control function and most data computation function.Though CPU (central processing unit) all has redundant configuration,, centralized structures shape, in case go wrong, be catastrophic certainly for whole device.Not only all control function can't be implemented, and all data of system also can't be shown to operating personnel, affected data, and hundreds of at least, can reach thousands of at most, allow operating personnel be difficult to the accident that manual handle occurs.
The central location that a core is arranged in the original system structure structure.All input blocks all will be delivered to this central location through bus from the data that industry spot collects, after calculating, handling (Control Software of the program of in store prior establishment or configuration in this central location), deliver to output unit through bus again, deliver to industry spot by output unit.So the central location in the original structure is the place that all data must be passed through, the quantity of these data often will be at hundreds of points even point up to ten thousand.If fault will cause the paralysis of total system, like this big data volume, personnel have no idea in time to handle, accident that might bringing on a disaster property.We in sum, the difference of system architecture is just at this central location.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of new dcs structure is provided.The fundamental purpose of dcs is decentralized control function, the management function centralization.Thereby reach the dangerous minimized purpose that local fault is brought total system in the system.
The technical solution of the utility model is:
A kind of new dcs structure, it is characterized in that: total system connects the control module of each distribution by a bus, all disposes chip of micro-computer, program storage, data-carrier store, nonvolatile memory, bus interface, redundant data exchange interface, the various IO interface of being equipped with mutually in all control modules.
Bus is Industrial Ethernet, fieldbus or RS-485 bus.
Program storage stores the fixed routine of finishing the unit basic function;
Data-carrier store stores various intermediate data, intermediate result;
Nonvolatile memory stores has the program, cumulative amount, state etc. of control configuration;
Bus interface connects the bus that realizes the exchanges data between all unit;
The redundant data exchange interface connecting bus that is equipped with mutually; Finish some important unit and can realize the redundant two units synchronization operations that are equipped with mutually.
Various IO interface connect the data-switching of controlled system industrial field device device and the interface of collection.
The utility model effect is:
Because all unit have all adopted computer chip, so, the control configuration program by system engineer's establishment all can independently be finished in each unit, and so just computing and the data processing with control program all is distributed to each unit, realized the thorough dispersion of fault danger.
Though the bus line is simple circuit, consider its importance, internal system adopts dual bus interface redundant mutually fully, the reliability and the security that further improve system.
The characteristics of this structure are exactly the hidden danger that does not have in the total system because of the partial failure affects overall situation.Ensured the safe operation of industrial installation.
Description of drawings
Fig. 1 is a kind of structural representation of new dcs structure
Embodiment
A kind of new dcs structure, the native system structure has been abandoned the bottleneck-CPU (central processing unit) of original system fully.All control function and data processing are all finished at each input-output unit, as Fig. 1.Control function and data processing function are disperseed up hill and dale, thereby accomplish dangerous thoroughly dispersion.Like this, even certain unit of system breaks down, also just influence the demonstration control of several data or state, operating personnel can handle calmly.
The specific implementation method is: all unit (module, integrated circuit board) all has chip of micro-computer, program storage, data-carrier store, nonvolatile memory, bus interface (bus can be Industrial Ethernet, fieldbus, RS-485 etc.), redundant data exchange interface, the various IO interface of being equipped with mutually.
Program storage is the fixed routine that the unit basic function is finished in storage;
Data-carrier store is the various intermediate data of storage, intermediate result;
Nonvolatile memory is the program, cumulative amount, state of storage control configuration etc.;
Bus interface is the exchanges data that realizes between all unit;
The redundant data exchange interface that is equipped with mutually is to realize the redundant two units synchronization operations that are equipped with mutually in some important unit, further improves the reliability of system.
Various IO interface are to realize the interface of data-switching and collection between control system and the industry spot.
Because all unit have all adopted computer chip, so, the control configuration program by system engineer's establishment all can independently be finished in each unit, and so just computing and the data processing with control program all is distributed to each unit, realized the thorough dispersion of fault danger.
Though the bus line is simple circuit, consider its importance, internal system adopts dual bus interface redundant mutually fully, the reliability and the security that further improve system.
There is not central location in the system architecture.All data all are to pass through bus directly to output unit from input block, through after the routine processes of output unit, deliver to industry spot.Each input block and output unit all have the function of data-handling capacity and programming.Because there is not this central location, and crucial signal even can one or several data just form an input block and output unit, even certain unit breaks down, also just have influence on the control of one or several data, operating personnel have the sufficient time to handle the situation of accident point.
The characteristics of this structure are exactly the hidden danger that does not have in the whole system because of the partial failure affects overall situation. Ensured The safe operation of industrial installation.
