For determining the sequential relationship of each subsystem in the emulation, the utility model introduces logical time and logical time stabs mechanism, and proposes a kind of synchronous startup scheduling strategy on this basis.
Logical time is to be used to write down and to represent that the sequential relationship that emulated data produces and the logic in the time interval measure, and the time of day of logical time was represented with the emulation cycle.In the single-rate analogue system, the length in an emulation cycle is a logical time unit; In the multi-rate simulating system, in order accurately to differentiate the sequencing that all emulated datas produce, the length of choosing the minimum emulation cycle is as a logical time unit.In the LAN (Local Area Network) distributed emulation, all interaction datas must just have practical significance with specific time correlation connection.In order to determine the interaction data sequential and to measure various forms of time delays in the emulation limitedly, in interaction data, introduce temporal information, i.e. timestamp.Because the interaction data sequential relationship in the Computer Simulation can be determined by logical time is unique, therefore can stab with the logical time express time, is called logical time and stabs.In the operational process of analogue system, each simulation subsystem advances the logical time of oneself under the management of emulation dispatch strategy, simulation subsystem added the logical time of oneself in the interaction data before sending interaction data, thereby the logical time of having realized interaction data stabs mechanism.
The core concept of the synchronous startup scheduling strategy that the utility model proposes is: in a whole set of analogue system, with the synchronous startup operation of all emulating host computers in the clock host computer control analogue system, increase the concurrency of each emulating host computer computing to greatest extent.
It is as follows to start the scheduling strategy course of work synchronously:
A1, with the synchronous startup operation of all emulating host computers of clock control of computing machine in the analogue system or clock main frame;
A2, for the single-rate analogue system, with emulation cycle of analogue system as a logical time unit; For the multi-rate simulating system, with minimum emulation cycle of each emulating host computer in the analogue system as a logical time unit;
A3, all emulating host computers are the logical time initial value with 0 all;
It is the timer of a logical time unit that A4, clock main frame are created the clock period, with 1 is the logical time initial value, adopt the Web broadcast transmission mode periodically to send and have the synchronous enabled instruction that logical time stabs, promote the periodic duty of whole simulation system to all emulating host computers; Every transmission one subsynchronous enabled instruction, logical time adds 1;
After A5, emulating host computer receive synchronous enabled instruction, if the timestamp of synchronic command is greater than the logical time of oneself, and when being the integral multiple of own emulation period ratio, emulating host computer stabs the logical time that oneself logical time is advanced to synchronous enabled instruction, start simulation calculating, and send simulation result with the network multipoint transmission mode; If above-mentioned condition does not satisfy, then do not do any processing.
Start scheduling strategy synchronously and have following principal feature:
B1, the synchronous operation under the unified control of clock main frame of all emulating host computers.When emulating host computer is output as input with the digital quantity of other emulating host computer, all will introduce the emulation dispatch delay;
B2, enabled instruction synchronously adopt the Web broadcast transmission mode to send, and the interaction data between emulating host computer can adopt the network multipoint transmission mode to send;
B3, realized the parallel running of all emulating host computers comprising the parallel transmission of interaction data and the concurrent operation of parallel receive and simulation algorithm to greatest extent;
Clock synchronization between B4, clock main frame can guarantee the clock synchronization between each simulation subsystem;
The time delay that B5, scheduling strategy are introduced can be stabbed by logical time and be measured, and can carry out delay compensation;
B6, scheduling strategy control simply are convenient to realize.
The active force that the utility model proposes with handle the complex optimum controlling schemes, help studying theoretically the integrated control method of ship motion and diesel engine, improve ship motion control effect; Help navigation safety; Help preventing the diesel engine overload and improve power plant service reliability and economy; Help setting up navigation and turbine comprehensive simulation device, improve the precision of simulator and crewman's the level of training.The utility model improves the macroeconomic of marine system for the synthesis energy saving optimal control that realizes boats and ships, prolongs the main power plant mission life with significant.Present China domestic marine equipment shipment rate less than 40%, the complete dependence on import of some crucial shipborne equipments, become " bottleneck " of the shipping industry development of restriction China, the utility model has China's independent intellectual property right, high technology content for exploitation, the homemade crucial ship control system of high added value, particularly boats and ships integrated driving platform system has the effect of actively promoting, thereby improves the shipment rate of China's domestic marine equipment.The utility model achievement both can adapt to sea transport boats and ships control system such as being used for container ship, oil carrier, roll-on-roll-off ship, also can be applied to big-and-middle-sized surface vessel, will produce huge economic and social benefit.
