Description

Ubiquitous object interaction interface method towards general manufacture and edge calculations

Technical field

The invention belongs to field of software engineering, are related to the back-up environment of internet of things oriented application and the building method of tool.

Background technique

With the proposition of the industrial revolution 4.0, new requirement also proposed to informationization technology.Industry internet, intelligence system It makes, intelligent robot, the industrial standards such as 4.0, industrial 2025 and technology are paid attention to.Support to these new demands, general manufacture It is major way.

General manufacture is a kind of important operation system that ubiquitous object blendes together realization.In short, ubiquitous object can summarize For people, object, machine, number, soft.Wherein, people and object refer to the object of not electronic data interface, belong to " object is not networked " object.Machine Refer to the instrument and equipment that can carry electronic digital interface and tool etc., number refers to electronic data, soft to refer to computer software system System, is generally presented with method of service.All things on earth interconnects, and refers to Coordination, integrated, the formation multiple agent of ubiquitous object Hybrid system, realize service logic.

General manufacture refers to all behaviors and work that can produce materialization result.Materialization result refers to substance, article Form existing for thing including traditional directly visible tangible thing and product also include existing for certain medium Originally invisible thing, such as all kinds of schemes, literary works, computer software, integrated circuit diagram, etc..

Therefore, general manufacture here also includes production in addition to the manufacture including product and article in traditional manufacturing industry Industry and service trade and the research of other industry, design and creation work.

General manufacture is the widened manufacture of scope that will be manufactured, by the pervious production for being included into service trade or other industry Affairs are also included in manufacture scope, and basic reason is with manufacturing development, and people have in depth recognized that many does not belong to In conventionally manufactured production affairs also, substantially belong to manufacture scope, for example, the creation of all kinds of technical solutions, all kinds of scientific skills The research and development of art, the creation of all kinds of literary works, the exploitation of computer software, personnel training, etc.." manufacture " of these types, The process of " manufacture " and mode and traditional manufacture difference are very big, but purpose is the same: generating the achievement of " materialization ", also It is to generate directly visible or indirect visible thing.Manufacture scope is included in these non-traditional manufactures, is conducive to uniformly locate It manages and complements each other development.

Therefore, general manufacture is extensive more than conventionally manufactured, and application range is also more extensive than traditional manufacture, therefore also has more Extensively with deep demand and market.

In the fourth industrial revolution, traditional industrial classification (first to the tertiary industry) will be not present, industry and life The boundary for producing, manufacturing, servicing will be cancelled, and industry will be with a kind of appearance of the form of synthesis, this is mainly reflected in terms of two: " system Make/produce " object it is unitized, the implementer of " manufacture/production " will unitize.Therefore, the concept of general manufacture should be the 4th One of the basic demand of the secondary industrial revolution.

Edge calculations refer to calculation processing nearby in the calculating mode of edge device Yu system side, can be popular regard as It is a kind of to calculate mode nearby.Edge device and system include instrument and equipment, data source, system implementation end.Calculating is the meter of broad sense It calculates, including processing data information, storage and transmission etc..Edge calculations are substantially a kind of distributed computings.In edge calculations, Target is that edge device and system is made to can receive control, to participate in calculating, and calculated result is sent.Therefore, it It asks edge device that there are computing capability, networked capabilities and service ability is provided.

Therefore, either edge calculations or general manufacture, wherein most basic requirement is that ubiquitous object is accessed network.

Four, monitor composition and working method

The core of interface unit is monitor software.Software composed structure is referring to Fig. 1

Monitoring software is by three kinds at being grouped as: engine, pendant, method base, data structure.

(1) pendant and method base

The software module that pendant has been construction standard is called or is started for message handling device or event transmitter, with reality The event of the Message Processing or specified event of now specifying message generates.The description of this " specified " relationship, passes through configuration file It carries out, this description referred to as " mounts ".

Method base is the customized standardized program module of user, is called for pendant, to realize complicated pendant function.

(2) data structure

Including message queue, transmit queue, event description table, pendant allocation list, ubiquitous object interaction image UOB.Message queue The message of the various tape handling of storage system；The message that transmit queue storage band is sent by network；Event description table defines thing The occurrence condition of part；Pendant allocation list defines the mapping relations of message handling device pendant and message.Ubiquitous object interaction image UOB External data are issued to for buffering ubiquitous object.

(3) engine

Engine is the software of cycle detection and listening mode work.With regard to carrying out cycle operation always after starting.Engine includes message Engine, event engine, transmitting-receiving engine, as shown in Figure 2.

Five, the working mechanism of monitor

The working mechanism of monitor is described below.

The work of ■ message engine: message engine monitoring information queue always, after finding pending new information, taking-up disappears Breath, calls corresponding message handling device to handle message.It is that user is according to service logic that user, which needs the groundwork cooperated, Demand, mounts the Message Processing pendant of corresponding service-oriented logical process on message engine, and mounting is described by piece supplying File is realized；Pendant is responsible for the tissue of message execution, and specific Message Processing is realized by pendant called side Faku County, needed at this time User setting method library module is called for message handling device；

Message engine implementation procedure is described as follows:

[1] it initializes；

[2] message queue message whether to be handled is checked；

[3] if without message to be processed, turn [1];

[4] (message to be handled) takes out message；

[5] message is analyzed, the corresponding Message Processing pendant of message is found out；

[6] start found out Message Processing pendant；

[7] turn [1]

■ receives and dispatches engine work: monitoring network request message and transmit queue, it is found that after standardized internet message reaches, connects Message is received, message is stored in message queue, while also detecting transmit queue, after there are internet message to be sent, execution disappears Breath sends work.It is to preset the message handling device of processing network request, be articulated to message and draw that user, which needs the groundwork cooperated, It holds up；If necessary to send data, then in the pendant for sending processing, generates and send message, be stored in transmit queue.

Transmitting-receiving engine implementation procedure is described as follows:

[1] it initializes；

[2] network port is monitored；

[3] if there is legitimate network request message reaches, turn [10];

[4] transmit queue message whether to be handled is checked；

[5] if without message to be processed, turn [];

[6] (transmit queue message to be handled) takes out message；

[7] message is analyzed, the corresponding Message Processing pendant of message is found out；

[8] start found out Message Processing pendant；

[9] turn [2]；

[10] (there is the arrival of legitimate network request message) and receive message instruction；

[11] analysis message instruction checks that legitimacy discards the message if unqualified, turns [13];

[12] network request message is generated, message queue is stored in;

[13] turn [4]；

The work of ■ event engine: event engine, which is responsible for periodically detecting event and defines table, calls event after discovery event occurs Generator pendant generates data and operation for event, the event occurred is then stored in message queue as message, for Message engine starts the processing to event.It is to define event according to business demand and define table that user, which needs the groundwork cooperated, Predeterminable event generator pendant and event handler pendant.Timing definition table describes the occurrence condition of each time, and when pointing out Between occur after call what pendant with the data and operation of generation time.

Event engine implementation procedure is described as follows:

[1] it initializes；Event is defined into table first defined item as current event definitions item；

[2] check whether current event definitions item meets event occurrence condition；

[3] if being unsatisfactory for event occurrence condition, turn [5];

[4] (current event definitions item meets event occurrence condition) if the corresponding event of current event definitions item generates pendant not Starting or failure pause, then start the pendant, which will generate corresponding data for event, and generate an event message It is stored in message queue；

[5] no by first event items as new current event definitions item if current event definitions item is last term Then next event defined item is turned [2] as new current event definitions item;；

Six, monitor key data structure

The work of monitor, based on key data structure include message queue, transmit queue, event defines table, pendant configuration Table and object interaction image.

■ message queue: currently pending message, including network request (reception) message and event message are stored.Network Request message is by the generation when listening to network request and reaching of transmitting-receiving engine；Event message checks event in event engine Afterwards, pendant is generated by event to generate.

■ transmit queue: the current network to be sent of storage sends message.Such message can be generated by various pendants, and be deposited Enter the queue.The queue has transmitting-receiving engine detection to send after transmission has message to be sent；

■ event defines table: being a sequence list, a certain item defines an event occurrence condition and corresponding event generator Pendant association.It is arranged automatically by user's manual configuration or work pendant.The table is detected by event engine, and discovery has the condition of satisfaction Event, then start event generator, prepare for the processing of event；

■ pendant allocation list: for describing message handling device association, message in message queue and corresponding can as be appeared in Processor pendant establish mapping.It is arranged automatically by user's manual configuration or work pendant.The table is detected by message engine, is disappeared Breath engine finds corresponding message handling device pendant by the table when analyzing message；

The ubiquitous object interaction image UOB of ■: the data buffer storage as general interaction between objects.One ubiquitous object is emitted to The data of other objects are stored in UOB, are then actively read from UOB by other related pendants.

UOB is mainly made of queue, comprising:

State queue: the status data that storage is read from object；

Command code queue: storage reaches the control command of object under；

Data object: the data from object or outside are cached；

Upper column data, each data item, all attachment have data head, indicate source and the whereabouts of data.The data of UOB are to user's journey Sequence person is transparent, and user is arranged UOB-API by system and accesses UOB.

Seven, pendant and system pendant specification

Pendant (PIP) is distinguished from the method for operation, is divided into odd-job pendant and farm labourer's pendant.Odd-job pendant starts only operation one every time It is secondary, it terminates and returns automatically after operation；It is in operating status always after normal work pendant starting, it is similar to service, usually thread shape Formula, until foreign intervention or internal completion overall timing.

Pendant is distinguished from the object of mounting, is divided into message handling device pendant and event generates pendant.Message handling device pendant Mounting love message processing engine, there is message processing engine starting.Event handling pendant is articulated in event engine, has event engine to open It is dynamic.

Pendant is distinguished from affiliated object, is divided into system pendant and user's pendant.User's pendant has that user is customized, for real Existing user logic；System pendant is the pendant of a kind of specific use, completes the function needed for monitor works normally.Main system System pendant include:

Network receives pendant: receiving internet message；

Network sends pendant: sending message from network；

System event generates pendant: internal system event generates pendant；

Pendant is object form formally, and a pendant is exactly a program language objects.

Each pendant object, it is necessary to have a starting method and several defined attributes, concrete model are as follows:

public enum PipName

Name constant needed for { // define pendant PIP

OneOff, // odd-job type

Loop // normal work type

// other title constant definitions

}

class PIP

{

PipName pipType;The operation type of //PIP

int start() {};// starting PIP；Return starting state: 0 be it is normal, other are mistake

int reStart() {};// restarting PIP；Return starting state: 0 be it is normal, other are mistake

int stop() {};// hang up PIP；Return starting state: 0 be it is normal, other are mistake

int cancel() {};The operation of // forced termination PIP；Return starting state: 0 be it is normal, other are mistake

int pipMain() {};The program body of //PIP is called by start or is started, completes specific PIP function

……….;// other methods are placed here, for above-listed method call

}

Eight, the basic application method of interface unit

Ubiquitous object is connected using interface unit, there is following basic step:

Step 1: connecting interface device.If interface unit is hardware, the port of interface unit is connected devices to；If interface unit It is software, then interface unit is deployed to interface unit container.

Step 2: if desired, setting method library, for PIP calling；

Step 3: it writes connection PIP: according to the requirement of specific equipment, writing and realize that equipment connection disappears with what other objects were connect It ceases processor PIP and its realizes module；

Step 4: it writes communication connection PIP: according to communicating requirement, writing the PIP of processing communication information and its realize module;

Step 5: deployment PIP: PIP configuration list file is write, each PIP and preset message relating are got up.

Step 6: it writes client: writing the client of application program according to the demand of application program.Client needs to visit It asks piece supplying, using seeking part OAI Access Integration piece supplying, and fetches access result.

Nine, monitor network transmission regulation

The transmitting-receiving engine of monitor is responsible for the network communication of system.Basic function is the monitoring and transmission for carrying out network and receiving message Monitor, after listening to messaging, according to transmission protocol receive or send message, calling system PIP implement network receive or Person's network is sent.According to the network transmission regulation sending and receiving data of monitor.

Monitor network transmission regulation is established on network communication protocol, can be carried out on various protocols, including TCP/IP, MQTT, HTTP and EIIP.

Monitor network transmission regulation must first be started transmitting-receiving in advance and be drawn with the progress of telegram mode, the both sides of network communication It holds up, is in listening state.Sender sends instruction, after recipient listens to, establishes transmission connection, hereafter carries out command reception, Primary communication is completed after finishing receiving, and connection disconnects.

Ten, message instructs

The instruction of monitor message is divided into three kinds: request instruction sends instruction and response instruction.

(1) request instruction

Request instruction is used to convey user's request message of (instruction sender) to specified monitor.Specific request content and place Reason mode is explained by the pendant of piece supplying.

Format:

"Request" <requestID> <messageNo> <object> < permit > [resMode] [parameters]

Illustrate:

The instruction is for issuing request instruction to specified monitor.The semanteme of request is explained by corresponding pendant.Monitor is only born Duty receives instruction, and calls corresponding pendant processing here.

Instruction pair command word requestID is specified by user, for the further classification or difference to request instruction.

Parameter is determined by user, is specifically explained by pendant for parameter needed for specified request.

The echoplex mode of the result of request, is specified by resMode

Permit is the pass of sender.Recipient will check the validity of the pass, the permission pointed out according to the pass Control the range and content of request.

MessageNo is message sequence number, is integer value, is described with 64 bits, when being from 1 day zero January in 2017 Rise to photos and sending messages when millisecond number.Each message of piece supplying has a corresponding message sequence number mark.Message sequence number is by disappearing Requestor is ceased to generate, if the same time has multiple message to generate, by generating precedence, subsequent each message be Add 1 on the basis of previous.

ObjectID: the identifier for the object that piece supplying is connected.One monitor can connect multiple objects, different pairs As defining different object identifiers.

Parameters: the parameter of message.

(B) instruction is sent

It sends instruction and sends data to monitor for user.

Format:

"Send" <sendID> <messageNo> <object> < permit > [resMode] [parameters]

Illustrate:

The instruction is for sending data to specified piece supplying.Monitor is only responsible for receiving the number carried in the instruction and instruction According to.Other affairs are all responsible for by corresponding pendant such as the data processing or storage to being received.

The coding line of paying of instruction has user oneself determination, is further discriminated between to Send meaning.For example, may indicate that desire Coding, format and the type of the data of transmission.

The data to be sent are included in parameters.

The processing result of transmission or the echoplex mode of state, are specified by resMode

The same Request of other parameters meaning

(C) response instruction

Execution state or result of the response instruction for the instruction to requestor echo request person.

Format:

"Respond" <replayID> <messageNo> <object> < permit > [resMode] [parameters]

Illustrate:

The instruction is for sending response message to specified monitor.It is asked if a monitor A has sent before first to monitor B It seeks message or sends message, and the resMode in message is indicated and needed B back response message, then B is handling message Afterwards, using the instruction back response message.

There are two types of response messages: condition responsive and data respond, and respectively corresponding secondary command word replayID is " StautsReplay " and " DataReplay ".First parameter in condition responsive is a JSON character string, and data are rung Should be other than first parameter carry the state of JSON format, second transmission also carries also carrying data block.

Object and messageNo is address and the message number of the message responded, they are all being rung of being previously received It answers in message and takes bring information.

Monitor is only responsible for receiving the data carried in the instruction and instruction.Other affairs, as to the data received Processing or storage, are all responsible for by corresponding pendant.

The secondary coding line of instruction has user oneself determination, is further discriminated between to Send meaning.For example, may indicate that desire Coding, format and the type of the data of transmission.

The data to be sent are included in parameters.

The processing result of transmission or the echoplex mode of state, are specified by resMode.

Network event queue: storage carrys out the message of automatic network or is sent to the message of network；

Object event queue: message of the storage from the ubiquitous object of inner port；

Internal event queue: message of the storage from the customized internal event of user；

The API of every kind of queue is similar, and main AP wants member function as follows:

GetEven (queue ID): (team's head) element is won in the queue indicated from " queue ID "；

ReadEven (queue ID): (team's head) element is won in the queue indicated from " queue ID "；

AddEvent (queue ID, event, priority): specified queue is added according to its priority for specified event.Commonly The event of priority is then added to queue end.

KillEvent (queue, event id): the specified event in specified queue is deleted；
