Embodiment:
The included network equipment of Emergency communication vehicle is: modulator-demodulator, demodulator, router, switch, wireless aps, optical transmitter and receiver, and wherein modulator-demodulator, demodulator, router, switch, wireless aps are supported SNMP, and optical transmitter and receiver is supported TCP/IP; Institute's serial equipment is: antenna servo control system and upconverter.Satellite communications vehicle centralized monitoring system runs on industrial computer, and industrial computer is realized and the interconnecting of other network by switch, industrial computer serial ports board is connected with serial equipment, so this centralized monitoring system completes the monitoring of satellite communications vehicle mobile unit in industrial computer this locality.Because the type of management equipment is different, so improve existing method from this two aspect that arranges of architecture and polling cycle.
Aspect architecture, this method is data-centered, according to the process of data transmission, carrys out division aspect, has formed data collection layer, data analysis layer and data presentation layer.In the inside of each aspect, according to the difference of carrying out function, divide module.Data collection layer is divided module based on equipment, comprises modulator-demodulator acquisition module, demodulator acquisition module, router acquisition module, switch acquisition module, wireless aps acquisition module, optical transmitter and receiver acquisition module, antenna servo control system module, upconverter module and data collection layer scheduler.Data analysis layer is converted to acquired original data the form of the required data of management system, according to the request of presentation layer, data are passed to concrete expression interface, so this layer only comprises data analysis layer scheduler.Presentation layer comprises Configuration Manager and fault management module, and each module comprises that several represent interface.The present invention carries out partition by fine granularities from transverse and longitudinal both direction to management system, and each aspect is equivalent to the combination of some administration modules like this.Reduce like this coupled relation between function, improved the efficiency that management system is carried out, also reduced the complexity that system realizes.
After dividing level and module, the present invention is based on producers and consumers's Model Establishment and connect adjacent module, realize organic linking between disparate modules and between layers.During this connection, based on first-in first-out (First-In-First-Out, FIFO), queue realizes, and fifo queue has guaranteed that scheduler carrys out response request according to the sequencing of task requests time, and task is forwarded to corresponding device data acquisition module.
Because need bi-directional message between data collection layer and data analysis layer, so producers and consumers is a kind of relativeness in this case, message wherein represents request task or response.When request task is passed to data collection layer from operation layer, operation layer is as the producer, and data collection layer, as consumer, connects the fifo queue of two aspects as buffering area.When the operation layer request of producing is thought, request task is put into buffering area; And if full between buffer empty, block operation layer thread until after the Free up Memory of buffering area, wake the operation layer thread having blocked up, just request task is put into buffering area.Data collection layer is monitored all the time buffering area as consumer and whether is had task requests, if there is request task, takes out this request task and is for further processing; Otherwise data collection layer thread will block, until wake it up after there is request task in buffering area.After data collection layer executes task requests, response results need to be back to operation layer.At this moment, data collection layer is as the producer, and operation layer, as consumer, connects the fifo queue of two aspects as buffering area, and its implementation is with above-mentioned consistent.
Adjacent two aspects utilize fifo queue to come transmission tasks request or response, utilize queue to come transmission tasks request or its response, make queue become message queue, transmit the message queue that represents task requests or its response.Operation layer and data collection layer all comprise a scheduler, and this scheduler forwards task requests or its response based on type of message.The effect of scheduler is to guarantee to carry out exchanges data between disparate modules or aspect, thereby guarantees between module, between aspect or between module and aspect, can facilitate, efficient, communicates by letter reliably, has kept the feature of extensibility and flexibility.The built-in dispatch list that represents message destination address of scheduler, first judges type of message after receiving message, then searches in scheduling whether have forwarding address, if existed, this message is put into the entry address of respective modules, otherwise is abandoned.The false code of forwarding messages is as follows:
//InQueue represents the entry queue of scheduler, and Map represents dispatch list, and object represents the message that scheduler is received, MessageName represents type of message
Inner at data collection layer, this has formed point centered by scheduler, the structure that the concrete data acquisition module of take is extension point.Between each data acquisition module and scheduler, still meet the relation between producers and consumers.Scheduler and each data acquisition module are worked independently of one another, and each data acquisition module independence image data, is back to scheduler with asynchronous system after image data completes like this.Because Ethernet interface network interface is two-forty port and serial ports is low rate port, adopt asynchronous collecting data mode to avoid port speed inconsistent and bring the problem of wait-for-response Time Inconsistency.
Aspect polling cycle, polling cycle becomes the key point of network management system execution efficiency.If initiatively polling cycle is too short, taken more bandwidth resources, affect the communication of regular traffic; If poll is oversize, cannot monitor the variation of some concrete state informations.Therefore this method has adopted the management strategy in dynamic polling cycle, to shortening the polling cycle that may have abnormality equipment, increases gradually polling cycle, until return to polling cycle initial value after it recovers normal condition.Data collection layer comprises a plurality of data acquisition modules, and each data acquisition module relates to initiatively poll device parameter.
Data collection layer scheduler is set up scheduling timetable, and every of scheduling timetable is an integer value, the initial value of indication equipment polling cycle.In each clock signal, arrive after scheduler, in dispatch list, the value of every all subtracts 1.If during the item that existence value is 0, represent that this corresponding equipment arrives state parameter collection constantly, is forwarded to corresponding device parameter acquisition module by clock signal.Scheduler will be revised the polling cycle value of each equipment according to collection result.
The polling cycle that data collection layer scheduler is each equipment arranges initial value T
i(1≤i≤N), and these polling cycle initial values equate, wherein T
i=2
n, N represents the quantity of managed devices, n represents integer.At some polls constantly, if the state parameter of equipment i or operational factor extremely or not within normal range (NR) time, shorten to T by the polling cycle of equipment i
i/ 2.At next poll constantly, if the state parameter of equipment i or operational factor still extremely or not within normal range (NR) time, continue to shorten polling cycle, polling cycle value shortens to T
i/ 4, the rest may be inferred until polling cycle foreshortens to 1s.And next poll constantly, normal if the state parameter of equipment i or operational factor are recovered, polling cycle becomes 2 times of current polling cycle, and the rest may be inferred until polling cycle returns to T
itill.
Whether the parameter value that // judgement gathers is in normal range (NR)
Initiatively the implementation procedure of poll equipment status parameter and running parameter is as follows:
(1) scheduler of data collection layer is set up scheduling timetable, and every of scheduling timetable is an integer value, the initial value of indication equipment polling cycle;
(2) clock module be take 1 second as cycle generated clock signal, puts it into the entry queue of data collection layer scheduler module after clocking;
(3) scheduler is according to scheduling timetable forwarded clock signal, and device parameter acquisition module starts execution parameter collection after receiving clock signal, after collection, in readjustment mode, is back to data collection layer scheduler, is then forwarded to data analysis layer scheduler;
(4) data Layer scheduler is received after data, resolves to the required form of presentation layer, in Network Weathermap interface, shows.
Device parameter inquiry based on operating personnel's request is as follows with the implementation procedure of revising:
(1) operating personnel's clicking operation in system is inquired about a concrete class parameter, inquiry request is sent to the entry queue of data analysis layer, and at this moment the thread of presentation layer will suspend, until the response of obtaining wakes it up;
(2) data analysis layer is inserted inquiry request the entry queue of data collection layer scheduler;
(3) data collection layer scheduler is received the entry queue that forwards it to immediately corresponding device data acquisition module after inquiry request;
