Embodiment
Fig. 1 is the logic diagram of proxy server embodiment one of the present invention, proxy server is used for the command from client to destination apparatus, and the proxy server of this embodiment comprises interface module 11, (ScriptParser) module 12 resolved by script, logic engine (LogicalEngine) module 13, session management (sessionmanager) module 14 and multiple Connection Service (socketservice) module 15, 15 ', and, script parsing module 12 is connected with interface module 11 respectively with session management module 14, logic engine module 13 is connected with script parsing module 12 and session management module 14 respectively, multiple Connection Service module 15, 15 ' is also connected with session management module 14 respectively.The logical construction of each module is described below respectively:
Interface module 11 is for receiving the instruction from client, namely session is started, and judge that from the instruction of client be real-time command or conditional order, wherein, when described real-time command comprises information and the command information of destination apparatus, described conditional order comprises the information of destination apparatus, conditional information and command information.The agreement etc. that the information of destination apparatus such as comprises the ID of destination apparatus, the password corresponding to destination apparatus, destination apparatus use; Conditional information such as comprises when condition, where condition, event condition, compound condition etc.; Command information comprises order or action.This interface module 11 is such as SPI (ServiceProgrammingInterface, service programming interface) interface module, and its communication way is much first, user can be allowed to call out and related transmitting information with RESTAPI as method of reseptance.
Described conditional information, for when the conditional order from client, is resolved to machine language by descriptive language by script parsing module 12.
Logic engine module 13, for after the conditional information after receiving parsing, sends the first notice to session management module 14; Also for monitoring condition instantly according to the conditional information after parsing, and when condition meets trigger condition instantly, send the second notice to session management module 14.
Session management module 14, for when the instruction from client is real-time command, is set up the online passage between respective objects device according to the information of destination apparatus, and the port numbers of described online passage and respective objects device is bound; And, command information is converted to the protocol format of respective objects device, is then sent to respective objects device; Also for when the instruction from client is conditional order, after receiving described first notice, set up the online passage between respective objects device according to the information of destination apparatus, and the port numbers of described online passage and respective objects device are bound; And, after receiving described second notice, command information is converted to the protocol format of respective objects device, is then sent to respective objects device.
Multiple Connection Service module 15 ..., 15 ' for maintaining described online passage and carrying out information forwarding according to described protocol format, and session management module sets up online passage by corresponding Connection Service module and respective objects device.Certainly, in other embodiments, also can by Connection Service module 15 ..., 15 ' and session management module merge into single executive program.
In some preferred embodiments, session management module 11 is also for after the session is completed, namely, after real-time command or CMOV to destination apparatus, discharge the memory headroom of corresponding real-time command or conditional order and remove the binding of port numbers, this content space, for storing online channel information and port binding information, can reduce resource contention like this and consume excessively, thus being promoted to the highest by network efficiency utilance.Session management module 11 is also for managing the port numbers corresponding to different token (token), and the on line state maintained between described port numbers and respective objects equipment, like this, when user breaks, can recover online without the need to carrying out again online or logging device.
In other preferred embodiments, logic engine module 13 is also for managing, controlling and monitor all various condition such as event (such as whether certain event occurs), time (whether such as certain time arrives), space (such as whether reaching certain position) instantly.And, all control entries are placed in internal memory or database, until condition has been performed or has judged that performing loop stops, and can allow like this between all SPI main frames and carry out data syn-chronization.
Should understand, in certain embodiments, instruction from client only may comprise real-time command, or, only comprise conditional order, correspondingly, the logical construction of proxy server is also changed accordingly, such as, when the instruction from client only comprises real-time command, script parsing module and logic engine module can be saved.
Fig. 2 is the logic diagram of information transmission system embodiment one of the present invention, this information transmission system comprise multiple client 20 ..., 20 ', multiple destination apparatus 30 ..., 30 ' and proxy server 10, proxy server 10 be connected to client 20 ..., 20 ' and destination apparatus 30 ..., between 30 '.The logical construction of proxy server 10 can refer to the embodiment shown in Fig. 1, does not repeat at this.Client 20 ..., 20 ' be application layer representative, comprise various mobile device, mobile unit, browser, robot and various contact user application all in this type of.Destination apparatus 30 ..., 30 ' must to be present on network, or can receive and come from the various on-line environments of network instruction.In one example in which, client 20 produces an instruction, and (this instruction can be real-time command, also can be conditional order) and be sent to proxy server 10, proxy server 10 processes received instruction and changes, and is sent to destination apparatus 30 by network.
Instruction from client has two kinds: real-time command and conditional order, and wherein, real-time command comprises information and the command information of destination apparatus, and conditional order comprises the information of destination apparatus, conditional information and command information.For real-time command, proxy server main purpose is exactly instruction process be sent on destination apparatus in real time.For conditional order, proxy server needs resolve its logic and connect in different destination apparatus according to demand, and wait condition triggers and again instruction is sent to destination apparatus.
