Description

A kind of system and method for deployment server

Technical field

The present invention relates to cloud service technical field, and in particular to a kind of method of deployment server, more particularly to one kind will The method that geoserver is deployed to cloud service platform.

Background technology

GeoServer is that the J2EE of OpenGIS Web server specifications is realized, can easily be sent out using GeoServer The server of cloth map datum, it is allowed to which user is updated to characteristic, deleted, insertion operation, can be with by GeoServer It is relatively easy to rapid communal space geography information between users.

And GeoServer map tile technology is the map for the certain coordinate range that will have been configured, if according to fixed Dry engineer's scale (tile rank) and designated pictures size, the square picture of some rows and columns is cut into server end, to refer to Fixed form preserves into image file, by certain naming rule and organizational form storage into the catalog system of server or In Database Systems, the static map caching of pyramid model is formed.Tile pyramid model is a kind of multiresolution level mould Type, from the pyramidal bottom of tile to top layer, resolution ratio is more and more lower, but the geographic range represented is constant, and it, which cuts drawing method, is According to the pyramid model structure of tile type map, the maximum zoom number of levels required by map service platform is determined, scaling The map picture that rank is minimum, map scale is maximum is used as pyramidal bottom, the corresponding map of each level of zoom correspondence Engineer's scale, according to the geographic coordinate range of survey region, calculates central meridian, if weight indexing belt method and coordinate system are formed Map relationship figure layer file under engineer's scale, and according to all marks of the division method for numbering serial of national fundamental GIS calculating Quasi- map sheet number, picture path, form the corresponding map tile storehouse of the map document in server end, are easy to client to tile storehouse It is indexed and searches.

And map tile technology is realized, common mode is exactly the tile map service by GeoServer servers Module GeoWebCache generates map tile and dynamic buffering, it is to avoid static cache due to map tile need it is advance Generation, the currency difference of map, user can not usually obtain the defect of the feedback of real geography information.

On the other hand, it is increasing along with the demand for map tile, it is simple rely on GeoServer servers and Dynamic buffering can not meet preservation map tile needs, therefore just introduce cloud service platform to store map tile, have It is exactly that GeoServer servers communicate connection with the Cloud Server in cloud platform that body, which is got on very well, and then GeoWebCache is generated Map tile be sent in Cloud Server preserve, that is, be equal to the issue bag GeoServer servers (map tile of GeoWebCache generations) directly transmits copy or copies to the application catalogue of Cloud Server；Or will Copy is sent after issue bag (map tile of GeoWebCache generations) decompression of GeoServer servers or copies to cloud clothes The application catalogue of business device.

And GeoServer servers are the WebGIS increased income a projects now, it leaves very clever in the design process Interface living, but in the realization transmission issue bag (map tile of GeoWebCache generations) of its acquiescence, do not account for deployment Demand onto the Cloud Server of cloud platform, when so usually there is client request map, because map tile is simply copied Shellfish or copy to Cloud Server application catalogue structure so that GeoServer servers receive request map message after, The map identification information that request map message can only be sent carries out the retrieval of traversal formula into Cloud Server, and retrieval rate is slow, makes Client receives and shows that the speed for the map tile being retrieved is very slow, or even occur being delayed and can not normally show long very much The problem of map tile, so it is accomplished by realizing new interface or module again in GeoServer servers, to reach WebGIS structures as GeoServer servers can be efficiently with the communicating requirement of Cloud Server.

In addition, being exactly that tile map service module GeoWebCache is required for being generated according to request map message every time Map tile, the real-time that can still influence client to receive.

The content of the invention

To solve the above problems, the invention provides a kind of system and method for deployment server, it effectively prevent existing Retrieval rate causes client to receive and show that the speed of the map tile being retrieved is very slow, occur being delayed too slowly in technology Long can not normally show map tile and influence client receive real-time defect.

In order to overcome deficiency of the prior art, the invention provides a kind of solution of the system and method for deployment server Scheme, it is specific as follows：

A kind of system of deployment server, including communicate what is be connected with the Cloud Server and client of cloud platform It is described with tile map service module GeoWebCache in GeoServer servers, the GeoServer servers Mapping table, memory module and read module are also carried in GeoServer servers.

Further, the GeoServer servers and the MemCache servers with multiple MemCache servers Cluster communication is connected, and each MemCache server-assignments have a numbering.

Further, the mapping table is used for recording map access request, the reading times of map access request, map visit Ask map tile mark required for request, the map tile sequence number, the MemCache servers for depositing the map tile Numbering, storage address and map tile storage in Cloud Server of the map tile in MemCache servers The mapping relations of location, the memory module is used for map tile storage into Cloud Server, and the read module is used for reading Tile map in Cloud Server, the initial value of the reading times of the map access request is 0, if the map tile is not stored Into MemCache servers, the numbering and the map tile of the MemCache servers of the map tile are deposited in MemCache Storage address in server is sky.

Further, the client includes PDA, notebook computer, PC or smart mobile phone.

Further, the method for the system of the deployment server, comprises the following steps：

Step 1：It is described when client sends map access request to ask map to GeoServer servers GeoServer servers are received after map access request, start read module searched whether in the mapping table exist with The consistent map access request of the map access request that receives；

Step 2：If in the presence of consistent map access request, just extracting all mapping notes including the map access request Record and the storage address of tile obtains map tile from MemCache servers or Cloud Server according to the map, get map Map tile is transferred in client after tile and shown；

Step 3：There is consistent map access request if not having, the map access request received is just passed to tile Map service module GeoWebCache, the tile map service module GeoWebCache according to come the map that receives with regard to visiting Ask request and shown to generate map tile and the map tile of generation is returned to client；

Step 4：Then start memory module and the map tile of generation is stored in MemCache servers or Cloud Server In, and build in the mapping table with the corresponding map record of the map access request received.

All map records including the map access request and according to the map tile are extracted described in the step 2 Storage address map tile is obtained from MemCache servers or Cloud Server and is got after map tile map Tile is transferred to the mode shown in client and comprised the following steps：

Step 2-1：Extract first it is all include the map record of the map access request, then proceed to extracting Map record in handle one by one, the mode handled one by one for first retrieve one by one the map record extracted storage should Storage address of the numbering and the map tile of the MemCache servers of map tile in MemCache servers whether be It is empty；

Step 2-2:If it is empty, storage address pair of the map tile in Cloud Server just in the map record Cloud Server sends the first acquisition request map tile message, and Cloud Server is just according in the first acquisition request map tile message Storage address of the map tile in Cloud Server take out the map tile, the first acquisition request map tile message Include map tile sequence number and storage address of the map tile in Cloud Server in the map record；

Step 2-3:Cloud Server is taken out after the map tile just including the map tile and first acquisition request First response message of the map tile sequence number in map tile message returns to GeoServer servers；

Step 2-4：If not empty, volume just to the MemCache servers for depositing the map tile in the map record MemCache servers corresponding to number send the second acquisition request map tile message, and the MemCache servers are just according to the Storage address of the map tile in MemCache servers in two acquisition request map tile message takes out the map watt Piece, the second acquisition request map tile message includes the map tile sequence number and the map watt in the map record Storage address of the piece in MemCache servers；

Step 2-5:MemCache servers are taken out after the map tile just please including the map tile and described second The second response message for obtaining the map tile sequence number in map tile message is asked to return to GeoServer servers；

Step 2-6：After handling one by one, the read module is just extracted from the first response message and the second response message All map tiles and map tile sequence number, and the corresponding map tile sequence number of tile comes map tile according to the map Client is sent to according to sequence to show, and the reading of the map access request in map record where the figure tile sequence number Number of times adds one.

It is described startup memory module the map tile of generation be stored in MemCache servers or Cloud Server and The mode built in mapping table with the corresponding map record of the map access request received comprises the following steps：

Step 4-1：Memory module is started each to distribute a ground according to sequence order the map tile of generation first Figure tile sequence number and an identifier are used as map tile mark, then store one by one in order of sequence, described to deposit one by one Storage mode performs step 4-2 to step 4-3 for the map tile in order of sequence to each generation；

Step 4-2：Can the inquiry message of map tile be stored to the MemCache server sets pocket transmission, it is described MemCache server clusters are received after the inquiry message, if map tile can be stored, just to the GeoServer servers The response message for including the numbering for specifying the MemCache servers for being used for storing map tile is returned to, such memory module is just carried The numbering for specifying the MemCache servers for being used for storing map tile is taken out, the map tile is sent to corresponding with the numbering MemCache servers and Cloud Server in store, then MemCache servers and Cloud Server exist the map tile The storage address of storage address and the map tile in Cloud Server in MemCache servers returns to described GeoServer servers, then map tile mark, the map tile sequence number, deposit the map tile The storage address and the map tile of the numbering of MemCache servers, the map tile in MemCache servers are in cloud Storage address in server is added in the mapping table as a map record, then the map in the map record The reading times of access request add one；

Step 4-3：If map tile can not be stored, just the GeoServer servers are returned can not be described MemCache server clusters store the response message of map tile, and the map tile is sent to cloud service by such memory module Stored in device, then storage address of the map tile in Cloud Server is returned to the GeoServer and taken by Cloud Server Business device, then map tile mark, the storage of map tile sequence number and the map tile in Cloud Server Location is added in the mapping table as a map record, then the volume for the MemCache servers for depositing the map tile Number and storage address of the map tile in MemCache servers be set to sky, and the map in the map record is accessed The reading times of request add one.

Further, the MemCache servers in the MemCache server clusters are after the full map tile of storage, The GeoServer servers can update request letter to the MemCache server sets pocket transmission by memory module Breath, the MemCache server clusters just return to response fresh information to the GeoServer servers, then memory module Just the reading times of setting quantity at most and MemCache servers numbering and the storage in MemCache servers Location extracts for the tile map corresponding to empty map record from Cloud Server, and is forwarded to the MemCache services The minimum tile map of reading times is replaced in MemCache servers in device cluster to be stored, and according to The storage address and numbering for the storage tile map that MemCache servers are returned update map record.

The client includes PDA, notebook computer, PC or smart mobile phone.

In other step 1 when client sends map access request to ask map to GeoServer servers often Map accessing request information is exactly sent to by client by GeoServer clothes via wireless communication module by 3G network Be engaged in device, for the sake of security, client by 3G network map accessing request information be sent to GeoServer servers it Before, often map accessing request information is encoded and the map accessing request information after coding returned by 3G network again Return in GeoServer servers, because being restricted by method, the map that 3G network often can not be after footpath straight grip coding is accessed Solicited message is transported in GeoServer servers, and will often combine other can believe the map access request after coding Cease the network being transported to straight in GeoServer servers and carry out transfer, so waste the network equipment for needing to set up, it is impossible to be high Effect realizes the purpose map accessing request information after coding being transported in GeoServer servers.

Map access request is sent to GeoServer servers come to ask map be to pass through in client in the step 1 Map accessing request information is sent to GeoServer services by client via wireless communication module by wireless communication networks Device, so includes the process that map accessing request information is sent to GeoServer servers by wireless communication networks as follows Step：

The step of being wherein directed to the client comprises the following steps：

Step A00：User transmits map access request letter by starting being used in the client first

The output module of breath is encoded to map accessing request information, then by the client of user with wireless Network sets up transmissions links, sets up startup after transmissions links and is obtained and institute for transmitting the output module of map accessing request information State the network type that client sets up the wireless network of transmissions links；

In step A00, the output module for being used for transmitting map accessing request information of the client starts just just Obtain setting up the network type of the wireless network of transmissions links with the client, client carries some energy under normal circumstances Enough establishing wireless networks with some network types found the module of transmissions links, such as synchronous to carry 2G modules, 3G module, to allow coding Map accessing request information afterwards unimpeded can be transmitted, and must be obtained and be obtained setting up the wireless of transmissions links with the client at the very start The network type of network.

Step A01：If the network type for setting up the wireless network of transmissions links with the client is 3G network type, For transmitting nothing described in the previous dynasty of map accessing request information of the output module of map accessing request information after transmission coding Line network delivery is gone directly message；

In step A01, because the interchanger in 3G network can not transmit the map accessing request information after coding, so The type that the wireless network will be judged before map accessing request information after transmission coding is 3G network on earth, If 3G network, just transmit through message to the wireless network to allow the map accessing request information after coding need not to allow friendship Change planes and dispose and pass to GeoServer servers straight.

In step A01 before the through message towards wireless network transmission, also comprise the following steps：

Step C00：The map access for judging to be now to after whether the information of transmission encodes by the coded system please Seek information；

Step C01：If the information of transmission that is now to is the map accessing request information after coding, just towards the nothing Line network delivery is gone directly message；

Step C02：Transmitted by the through message and via wireless network towards GeoServer servers after the coding Map accessing request information；

Except the type that judge the wireless network is on earth 3G network, it must also judge to be now to the information of transmission Map accessing request information after whether encoding；, just must be via the nothing if the map accessing request information after non-coding Gauze network execution corresponding position, which is postponed, passes to GeoServer servers；If the map accessing request information after coding, with regard to palpus Obtain straight via wireless network transmission and without by disposal, the map accessing request information after the coding is passed to wirelessly After network, the wireless network judges to be now to the map accessing request information after whether the information of transmission encodes, if it is determined that Appear in the information to be transmitted be coding after map accessing request information after, described in the straight grip of footpath encode after map access request Information transmission is to GeoServer servers.

And for the wireless network the step of comprise the following steps：

Step D00：Set up the wireless network after transmissions links and obtain the visitor that transmissions links are found with the establishing wireless network The connected mode at family end；

In in the step D00, the wireless network is obtained and the client of the vertical transmissions links of the establishing wireless network Connected mode, corresponding transmission is run by the connected mode for the client that transmissions links are found with the establishing wireless network and is marked It is accurate.

Step D01：If the connected mode that the client of transmissions links is found with the establishing wireless network is 3G communication modes, It is determined with before map accessing request information so after transmission coding and do not receive through message；

In step D01, if it is 3G communication parties to found the connected modes of client of transmissions links with the establishing wireless network Formula, the unimpeded transmission of map accessing request information that allow after encoding, in before the map accessing request information after the transmission coding Be determined with and do not receive through message, the map accessing request information after the coding received is transmitted straight and should not Disposed by corresponding transmission standard.

Step D02：If receiving through message, step D03 progress is branched to；If confiscating by through message, branch to Step D04 is carried out；

Step D03：The map accessing request information after the coding is delivered to GeoServer by the through message Server；

Step D04：Terminate transmission；

Because the wireless network does not know that the information received is the map accessing request information after the coding, only The information for the client transmission being only clear that under 3G communication modes, thus must judge whether there is through message, if it has, It is the map accessing request information after the coding to mean that the information received, thus need not be towards the ground after the coding Figure accessing request information is disposed and is delivered to GeoServer servers straight.

It is determined with and is not received before through message in step D01, including performs following steps；

Step E01：Map access after whether the information received now by coded system judgement encodes please Seek information；

Step E02：If the map accessing request information after coding, decides that whether receive through message.

The map access request after whether the information received encodes now is so first judged by the coded system Information, if the map accessing request information after coding, decides that whether receive through message, if receiving through disappear Map accessing request information after breath, the coding received with regard to footpath straight grip is delivered to GeoServer servers, if not receiving straight Up to message, termination message is transmitted.

Via the network type for the wireless network that transmissions links are set up with the client, if set up with the client The network type of the wireless network of transmissions links is 3G network type, is existed for the output module that transmits map accessing request information The through message of wireless network transmission, allowed the wireless network straight described in the previous dynasty of map accessing request information after transmission coding Map accessing request information after the coding received is delivered to GeoServer servers and disposal need not be implemented, allows existing 3G network can transmit the map accessing request information after coding, and some network equipments can be compatible to, it is possible to reach 3G The efficient transmission purpose of map accessing request information after the coding of user.

Embodiment 5

The client includes PDA, notebook computer, PC or smart mobile phone.

Step A00：User transmits the output of map accessing request information by starting being used in the client first Module is encoded to map accessing request information, and the client of user then is stood into chain with establishing wireless network Connect, set up startup after transmissions links and obtained and client foundation biography for transmitting the output module of map accessing request information The network type of the wireless network of defeated link；

And for the wireless network the step of comprise the following steps：

Step D04：Terminate transmission；

The Cloud Server will be arranged in switch board in order to dust-proof, seen to monitor the temperature of switch board in real time Whether the temperature for examining switch board meets the normal working temperature of 20 DEG C~45 DEG C scopes needed for Cloud Server, past in switch board It is past that temperature sensor can be set, and temperature sensor is connected with controller, controller is connected with display screen, so just Observation can be realized by display screen, but continuously observation is unlikely that, also lacks judge in switch board in addition Whether temperature is in the determination methods of the temperature range of server normal work.

The first critical data KP₁Derivation formula such as formula (1) shown in：

Here t is the quantity of the randomly selected temperature data for being more than 20 in 20 DEG C~45 DEG C of interval range, T_uIt is Randomly selected u-th of temperature data, u is the positive integer more than 0；

Step S2：If the first critical data KP₁Not less than obtained temperature data, it is dry to decide that obtained temperature data Disturb data, return to step S1；If the first critical data KP₁More than obtained temperature data, decide that obtained temperature data is The temperature data normally obtained；

Step S3：Then the temperature data normally obtained is replaced described randomly selected be more than in 20 temperature data One；

Step S4：Derive that temperature data changes percentage T_mWith temperature data change frequency T_n, derive formula for example formula (2) and Shown in formula (3)：

Here T_sFor it is current at the time of s when described in obtained temperature data；T_lTo be used as the temperature data of reference；The Δ s For the upper one temperature data co-occurrence normally obtained for replacing randomly selected one be more than in 20 temperature data When at the time of s interval period size；T_(s-Δs)Described randomly selected be more than in 20 temperature data is replaced for upper one The temperature data normally obtained of one；

The temperature data T as reference_lDerivation formula such as formula (4) shown in：

Step S5：If the temperature data changes percentage T_mNo more than the second critical data, in addition plus temperature data Change frequency T_nUnder conditions of no more than the 3rd critical data, return to step S1；If the temperature data changes percentage T_mIt is more than Second critical data, in addition plus temperature data change frequency T_nUnder conditions of the 3rd critical data, step S6 is performed, this In the second critical data be 25%, and the 3rd critical data be 0.5 DEG C/sec；

Step S6：The temperature data is sent to display screen and changes percentage T_mWith temperature data change frequency T_n, and start Alarm equipment alarm.

In step s 5, it is by decision condition：If the temperature data changes percentage T_mMore than the second critical data, Temperature data change frequency T is added in addition_nUnder conditions of the 3rd critical data, step S6 is performed, here the second critical number According to for 25%, and the 3rd critical data is 0.5 DEG C/sec, and abnormal state can be thus found under many situations and is also carried out Alarm, adds out temperature data and changes percentage T in addition_mWith temperature data change frequency T_nJoin together to judge, improve judgement Accuracy, can prevent that the work of abnormal state from consuming.

Step 4-3：If map tile can not be stored, just the GeoServer servers are returned can not be in the MemCache Server cluster stores the response message of map tile, and such memory module is sent to the map tile in Cloud Server and deposited Storage, then storage address of the map tile in Cloud Server is returned to the GeoServer servers by Cloud Server, so It assign map tile mark, the storage address of map tile sequence number and the map tile in Cloud Server as one afterwards Bar map record is added in the mapping table, then the numbering and the ground of the MemCache servers for depositing the map tile Storage address of the figure tile in MemCache servers is set to sky, and the reading of the map access request in the map record Number of times is taken plus one.

8. the method for the system of deployment server according to claim 7, it is characterised in that the MemCache servers MemCache servers in cluster are after the full map tile of storage, and the GeoServer servers can pass through memory module To update solicited message to the MemCache server sets pocket transmission, the MemCache server clusters are just to described GeoServer servers return to response fresh information, then memory module just the reading times of setting quantity at most and The numbering of MemCache servers and the storage address in MemCache servers are the tile corresponding to empty map record Map is extracted from Cloud Server, and is replaced in the MemCache servers being forwarded in the MemCache server clusters The minimum tile map of reading times is changed to be stored, and the storage tile map returned according to MemCache servers Storage address updates map record with numbering.

9. the method for the system of deployment server according to claim 5, it is characterised in that in client in the step 1 It is to be led to by client via wireless communication module that map is asked in end to GeoServer servers transmission map access request Cross wireless communication networks and map accessing request information is sent to GeoServer servers, so pass through wireless communication networks handle The process that map accessing request information is sent to GeoServer servers comprises the following steps：

Step A00：User transmits the output module of map accessing request information by starting being used in the client first To be encoded to map accessing request information, the client of user is then found into transmissions links with establishing wireless network, built Start the output module for being used for transmitting map accessing request information after vertical transmissions links to obtain setting up chain with the client The network type of the wireless network connect；

Step A01：If the network type for setting up the wireless network of transmissions links with the client is 3G network type, it is used for Transmit wireless network described in the previous dynasty of map accessing request information of the output module of map accessing request information after transmission coding The through message of network transmission；

Step C00：Judge to be now to the map access request letter after whether the information of transmission encodes by the coded system Breath；

Step C01：If the information of transmission that is now to is the map accessing request information after coding, just towards the wireless network The through message of network transmission；

Step C02：The ground after the coding is transmitted towards GeoServer servers by the through message and via wireless network Figure accessing request information；

And for the wireless network the step of comprise the following steps：

Step D00：Set up the wireless network after transmissions links and obtain the client that transmissions links are found with the establishing wireless network Connected mode；

Step D01：If the connected mode that the client of transmissions links is found with the establishing wireless network is 3G communication modes, so It is determined with before map accessing request information after transmission coding and do not receive through message；

Step D02：If receiving through message, step D03 progress is branched to；If confiscating by through message, step is branched to D04 is carried out；

Step D03：The map accessing request information after the coding is delivered to GeoServer services by the through message Device；

Step D04：Terminate transmission；

Step E01：Map access request after whether the information received now by coded system judgement encodes is believed Breath；

10. the method for the system of deployment server according to claim 5, it is characterised in that the Cloud Server is placed In switch board, temperature sensor is set in switch board, and temperature sensor, display screen are connected with alarm with controller Connect；

Start controller and perform following flow：

S1：Controller is continuously available the temperature data in the switch board by temperature sensor, and obtained temperature data is same The temperature data of setting is contrasted, and the way of contrast is：

The first critical data KP₁Derivation formula such as formula (1) shown in：

{KP}_{1} = \sqrt{\frac{9}{t} Σ_{u = 1}^{t} {(T_{u} - \frac{1}{t} Σ_{u = 1}^{t} T_{u})}^{2}} + \frac{1.1}{t} Σ_{u = 1}^{t} T_{u} - - - (1)

Here t is the quantity of the randomly selected temperature data for being more than 20 in 20 DEG C~45 DEG C of interval range, T_uIt is random choosing U-th of the temperature data selected, u is the positive integer more than 0；

Step S2：If the first critical data KP₁Not less than obtained temperature data, it is interference number to decide that obtained temperature data According to return to step S1；If the first critical data KP₁More than obtained temperature data, it is normal to decide that obtained temperature data Obtained temperature data；

Step S3：Then the temperature data normally obtained replace it is described it is randomly selected be more than in 20 temperature data one It is individual；

Step S4：Derive that temperature data changes percentage T_mWith temperature data change frequency T_n, derive formula such as formula (2) and formula (3) It is shown：

T_{m} = \frac{T_{s} - T_{l}}{T_{l}} * 100 % - - - (2)

T_{n} = \frac{T_{s} - T_{(s - Δ s)}}{Δ s} - - - (3)

Here T_sFor it is current at the time of s when described in obtained temperature data；T_lTo be used as the temperature data of reference；The △ s are upper One replaces the randomly selected temperature data normally obtained of one being more than in 20 temperature data with current Moment s interval period size；T_(s-△s)Randomly selected one be more than in 20 temperature data is replaced for upper one The temperature data normally obtained；
