Embodiment
As shown in Figure 1, overlap spacecraft hot vacuum environment analog machine centralized monitoring system adopts the real-time data base means of communication of one-to-many and the network issue means of communication to realize more.
Whole centralized monitoring system is divided into three levels among Fig. 1, is respectively mechanical floor, server layer, client tier.Mechanical floor mainly comprises all on-the-spot testing equipments, test software and test real-time data base.The all devices of mechanical floor and the number of software are all determined.Server layer mainly comprises server, the redundancy backup server of Centralized Monitoring.Server layer equipment and software number and software communication method, redundancy approach are also determined.Client tier mainly comprises all long-distance user operating sides.The number of the client of client tier can increase arbitrarily or reduce.
The real-time data base means of communication by one-to-many between mechanical floor and the server layer realize.Each equipment and server all are furnished with real-time data base, and the database of these equipment provides data as the data source end for server database, and the data point in these device databases is corresponding one by one with the data point in the server database.Realize that by the set to server database point remote centralized operates all on-the-spot hot vacuum environment analog machines at server layer.This long-distance communicating method makes mechanical floor be connected reliably with the server layer data, the communication data amount is little, the operation response is rapid.
Communication is by the network distribution method communication between server layer and the client tier.Server end is issued its operation interface to whole upper layer network, and any one client can be operated the thermal vacuum test facility at scene by the operation pages on the general browser game servers such as IE as long as normally insert this network.This long-distance communicating method is that the communication between server layer and the client tier has brought easy extendability with compatible.
Whole many cover hot vacuum environment analog machine centralized monitoring systems adopt the means of communication based on real-time data base and network issue, not only can realize the Centralized Monitoring of many cover hot vacuum environment analog machines, also make this system have reliability, rapidity, easy extendability and compatibility concurrently.
The software systems network architecture of many cover hot vacuum environment analog machine centralized monitoring systems is divided into three parts: Monitor And Control Subsystem, remote monitoring client in the next on-the-spot thermal vacuum test subsystem, the co-level as shown in Figure 2.The next on-the-spot thermal vacuum test subsystem software is by writing software, control vacuum, low temperature parts in the thermal vacuum test facility by plc communication in ICP/IP protocol and the field control cabinet, obtain thermal vacuum test data and control process of the test by data acquisition unit, temperature controller etc. in the thermal vacuum test process equally.Monitor And Control Subsystem software is that core is write with a real-time data base in the co-level, by these data and the next on-site supervision subsystem swap data, reaches the purpose of remote monitoring thermal vacuum test facility and test.The remote monitoring client is by up-to-date interface network distribution technology, the software of specialty need not be installed, can land upper remote centralized control system interface by general browsers such as IE, thereby realize the control of thermal vacuum test facility and process of the test by operation interface.
The software communication structure of many cover hot vacuum environment analog machine centralized monitoring systems also is divided into three levels: the communication in the communication in the communication of the next on-the-spot thermal vacuum test subsystem inside, the next on-the-spot thermal vacuum test Monitor And Control Subsystem and the co-level between Monitor And Control Subsystem, the co-level between Monitor And Control Subsystem and the Terminal Server Client.
The communication of Monitor And Control Subsystem realizes synchronously by one-to-many real-time data base point in the next on-the-spot thermal vacuum test subsystem and the co-level.This working method can guarantee reliability and the real-time of data interaction, realizes by multithreading synchronously between the real-time data base point.The Monitor And Control Subsystem major function is exactly equipment control and the test figure of all thermal vacuum test facilities of centralized management in the co-level, thereby forms the data that main real time database management is managed equipment in all nets.In order to guarantee that Monitor And Control Subsystem gets the data consistance in the next on-the-spot thermal vacuum test subsystem and the co-level, the multi-threaded network communication means that adopts, guaranteed in 20ms, to upgrade the data in the database one time, in the thermal vacuum test cycle with respect to 1 minute, had enough real-times.Every 20ms during communication, Monitor And Control Subsystem sends data acquisition request (each on-the-spot subset has different IP addresses) to each on-the-spot thermal vacuum test Monitor And Control Subsystem simultaneously in the co-level, passes all data in 20ms back.Consistance and the real-time of Monitor And Control Subsystem data in the next on-the-spot thermal vacuum test subsystem and the co-level have been guaranteed by this method.
And adopt the remote measurement and control technology of network issue between the Terminal Server Client.This technology makes in the quantity of client and software installation etc. all under the not controlled situation, can also carry out browsing and controlling in the co-level on the Monitor And Control Subsystem of the on-the-spot thermovacuum equipment of certain authority and trystate.The thin-client structure of this standard has overcome the uncertain defective of client original state, has realized the target of " access is observing and controlling ".Other Add-onses need not be installed, by the human-computer interaction interface homepage of Monitor And Control Subsystem computing machine in browser visit co-level, client can obtain with co-level in software interactive interface like the software class that moves on the Monitor And Control Subsystem computing machine.When Terminal Server Client inserts, sending to engineering machine when asking first, browser is from control of slip-stick artist's downloaded.This control i.e. this control of registration in the client computer registration table.Call the server controls interaction data that moves on this control and the slip-stick artist's computing machine by browser and realize the function that remote interface is browsed.
Hardware design structure in this application is simple, open system is convenient to expansion and maintenance.The software design has taken full advantage of the real-time reliability based on one-to-many real-time data base technology, and the advantages such as O﹠M simplicity of delivery network technology Network Based.This method not only makes the reliable and stable of on-the-spot observing and controlling, and slip-stick artist's computing machine can requirement of real time, and long-range client also can be convenient landing and controlling fast and safely.This is used and successfully passes through debugging, and drops in the actual spacecraft parts hot vacuum environment test and use.
