Embodiment
The present invention is based on existing mine information system business service and contextual information are provided, construct a mine wisdom service system, existing business service is combined with contextual information, the information service of context aware is provided for down-hole miner.
System obtains for contextual information, mainly is through the existing personnel location system in colliery, obtains the residing geographical location information of miner; Through being associated, obtain the miscellaneous service information of this position then, comprise gas density, potential safety hazard, nearest survival capsule position or the like with existing service system; At last, business information is sent on the terminal equipment that the miner carries, satisfy the individual demand that the down-hole miner information service customizes.
Context-aware services system proposed by the invention is as shown in Figure 1; This system sets up the loose coupling incidence relation between contextual information and the business service through the allocation models definition; Select corresponding configuration to call business service according to the contextual information value of monitoring then, and then realize context-aware services.System framework mainly comprises following three parts:
The contextual information acquisition module: contextual information can directly be obtained through terminal equipment or transducer simply and intuitively.This module is managed contextual information itself, comprises expression, filtration, reasoning, storage and the inquiry etc. of contextual information, its objective is to set up the sharing of an environmental model unification, open and environmental information, use and administrative mechanism.For example, miner's positional information can be obtained through personnel location system, stores as the data of contextual information then.
The contextual information reasoning module: after having obtained first hand, detectable context data, some abstract complicated situations then need comprehensive known situation to carry out reasoning and judging, just can draw the complete situation of client's present located then.At present, according to the difference of situational model, main inference method is divided into rule-based method and based on two types of the methods of body.For example, after obtaining the miner position, need judge whether that the data of preserving with the last time are identical, only when changing, store again, otherwise can cause data volume excessive and meaningless.
Business service provides module: when setting up context-aware services; Except the contextual information that will gather the service object; Also need set up the incidence relation of different contextual information and business service, explain under which kind of situation (which kind of condition is the value that specifically can be meant which kind of contextual information satisfy) which kind of service the user needs; Judge the contextual status of current service object then according to the contextual information value of perception, corresponding service is provided.Present colliery existing various information system, for example gas-monitoring, potential safety hazard identification, emergency command etc. can be packaged into business service, and service system basis situation is on the spot called, thereby meets customer need.
Be illustrated in figure 2 as the flow chart of the mine method of servicing that the present invention is based on situation, comprise:
Step 104, carry out business service if desired, then carry out content with the value corresponding business service of said contextual information.
Through concrete example implementation procedure of the present invention is described below.
One, contextual information collection
The colliery underground mining is vast in territory, if only adopt local radio sensing network, and neither one backbone transport net support reliably at a high speed, then underground safety monitoring information can't in time pass to the ground maneuvers center.Widely used various supervisory control systems are the outstation mode that on EPA or fieldbus networks, articulates basically at present, realize collection and Equipment Control to ground and downhole parameters.From economic, practical angle; The collection of contextual information can be based on existing mine personnel positioning system; Be illustrated in figure 3 as the system configuration sketch map that contextual information is gathered among the present invention, mainly comprise positioning label, terminal equipment, locating base station, Ethernet and service system 5 parts.In the time of down-hole miner process locating base station, its label on one's body can be passed to the base station with Wireless transmission mode with miner's personal information, is transferred to service system through Ethernet after the base station is carried out data transaction and handled.After service system is analyzed data,, comprise individual's positional information, gas concentration and nearest escape compartment position etc. if unusual circumstance is sent alarm signal to the terminal equipment that the miner carries immediately.
The outward appearance of terminal equipment can be similar to electronic watch; Can be worn on the wrist; Be illustrated in figure 4 as a kind of structural representation of terminal equipment among the present invention, it mainly comprises RFID label, central processing unit (for example, can be the MPS430F149 single-chip microcomputer), memory and display etc.The MPS430F149 single-chip microcomputer is 16 single-chip microcomputers, has the A/D change-over circuit, and higher switching rate is arranged, and antijamming capability is more intense, is particularly suitable for the processing of mass data.The RFID label of existing personnel in the pit's navigation system is integrated in the terminal equipment, is used to identify miner's personal information.Context information and business service information through wireless radio frequency circuit obtains from the base station after the MPS430F149 single-chip microcomputer is handled, temporarily store corresponding memory cell into.Display mainly can make things convenient for the site environment situation of understanding self present position in real time for coal miner, if emergency is arranged, has beep or vibration function, thereby initiatively reminds the user.
The MPS430F149 single-chip microcomputer is connected with the wireless communication module that has ICP/IP protocol through the RS232/485 serial ports, and data send to radio data network after the protocol encapsulation packing.Wireless module can adopt Shandong to make every effort to achieve the LQ-8100GRRS module of company, has high stability, can realize the wireless data real-time Transmission, is embedded with ICP/IP protocol, has high transfer rate, always online characteristics.The DB9 needle interface that this LQ-8100 wireless transport module has standard (comprises power interface; Operating voltage 5v), SIM interface, standard RS232/485 interface etc.; Adopt GSM900 and two frequency ranges of GSM1800, can support two kinds of mode of operation: circuit switched mode CSD and packet switched mode.Its function is that the collection in worksite data are launched through being connected antenna with it, or receives the data that send at the remote monitoring center, again corresponding protocol processing is carried out in the data that receive or order after, send into central processing unit through serial line interface and handle.Serial RS232/485 interface electrifies to flat turn and changes the function with serial communication.
Two, contextual information is handled
Contextual information generally can't directly be obtained through sensor layer, but needs the basis and the incidence relation of other contextual information to judge.Loose coupling and trigger-type according to context-aware services call characteristic, and a kind of contextual information that is illustrated in figure 5 as the present invention's proposition is handled the sketch map of framework, and this framework comprises contextual information definition and 2 parts of situation inference engine:
The contextual information definition.Because the contextual information of sensor layer source is widely different; Use for ease of the context aware engine; Framework is through facility information access interface DIA (Devices Information Access) shielding lower floor various contextual information source, on demonstrate a unified context data access interface.The definition of situation: cxt=< ID, Ctype, OType, VType, Provider, SEN >
Wherein ID is the identification information of cxt.
CType is the affiliated classification of cxt, and classification possibly have hierarchical structure, usually by domain expert's definition, has versatility as a kind of industry common recognition.For example the position can be divided into subclasses such as GPS, BlueTooth and WiFi as the contextual information of parent level according to location technology.
OType is the type of obtaining of cxt, and can be divided into three kinds of collection type, reading out type and inference type according to the difference of obtain manner.Wherein collection type is meant can be directly to be gathered through hardware device, has the contextual information of realistic meaning directly perceived, like temperature, time, position etc.; Reading out type is meant from can't passing through the hardware device collection, but the contextual information that reads from software systems inside, like various states; The collection type is directly to obtain from the external world with reading contextual information, and inference type then is need be through relevant contextual information is carried out the secondhand contextual information of reasoning.
VType is the value type of cxt, and the value of situation can be divided into two types of discrete type and continuous types.Discrete type is meant that the value of cxt is the limited fixed value of number, and for example the character type in Obj State, the positional information is represented etc., and continuous type is meant that the value of cxt is unlimited successive value, and the coordinate type during for example temperature, time, positional information are represented is represented etc.
Provider is the provider of cxt.
SEN is the set of sensors of cxt, and this set is the cxt of collection type to OType only.
The contextual information reasoning.The context aware engine is the core of framework, comprises interrogator, inference engine, calls controller and Service Quality Management.Interrogator is called the value that the DIA interface obtains contextual information according to the frequency acquisition of contextual information, then value is passed to inference engine.The context aware engine uses the inference rule of contextual information, thereby supports calling business service.Below specify the setting and the use of inference rule.
Define 1. value condition cv=<obj, cxt, v
Cxt>, relation condition cr=<obj, relation, obj>, wherein
(1) obj is an object; Cxt is a contextual information; v
CxtIt is the contextual information value;
(2) relation is a relation between objects.
Definition 2. Mapping
inference rules
where
(1) A is the precondition collection; S is the postcondition collection;
(2) A and S satisfy following constraint:
1. to any A, if
arranged then must have cv ∈ A;
2. to any S,
arranged and must not have cr ∈ S.
Precondition collection A possibly be made up of value condition and relation condition jointly, but must comprise the value condition; Postcondition collection S only is made up of the value condition.
To judge whether down-hole miner is in the hazardous area is example, supposes that the miner is in certain bar tunnel, and the gas density in this tunnel exceeds standard, and it is in the hole so just to derive this miner.This example comprises people, position, tunnel and 4 obj of gas; Has relation attribute locate-in between gas and the tunnel; Position and safe condition are people's cxt, and concentration index is the cxt of gas.Foregoing can use following inference rule to describe:
A={ < people, position, tunnel >, < gas, locate-in, tunnel >, < gas, concentration index exceed standard>}
S={ < people, safe condition, danger>}
Three, business service provides
Shown in Figure 6 for calling the schematic flow sheet of business service among the present invention.Business service in the context-aware services can be provided by the existing various information systems in colliery, and for example potential safety hazard investigation system provides the information of the potential safety hazard in the Coal Production; Emergency rescue system provides various emergency informations, for example the position of survival capsule, escape route etc.; Methane monitoring system provides the gas information of each position, down-hole; Personnel location system provides the residing positional information of miner individual etc.The function of information system is through after the service encapsulates, and the mechanism that just can be called is called.Be sent to after collection of contextual information process and the reasoning and call controller analysis, judging whether to call and specifically calling which business service to who user provides, and this is the core of service system.
Service system defines contextual information and business service respectively, carries out association through rule or configuration, triggers according to the contextual information value and calls corresponding business service.The association definition of this mode is comparatively flexible, and supports contextual information to reuse.Because user's behavior is a dynamic random, the variation of contextual information and the time of variation are difficult to calculate.The trigger-type call-by mechanism that the present invention adopts poll----to call is carried out business service and is called, and only when contextual information first fit condition, provides usually, triggers when promptly the contextual information value changes and calls.It is following to call control algolithm:
Input: allocation models set, Information Monitoring set, cache information;
Output: business service set;
Key step comprises:
Step 1: initialization;
Step 2: search all collection values that change and upgrade buffer memory;
Step 3: trigger control when changing and call;
Step 301: search and receive personal information and the context-aware services thereof that the contextual information value changes to be influenced;
Step 302: the up-to-date collection value of searching all contextual information of context-aware services;
Step 303: search the required business service of calling;
Step 4: call this service.
Four, run the example
For at present a lot of collieries, all disposed personnel in the pit's navigation system, can get access to the positional information of down-hole miner, also can recognize the gas concentration of each position, down-hole simultaneously through methane monitoring system.But any association does not take place in two systems at present, and down-hole miner is difficult to be directly acquainted with the gas concentration of self present position, can't make full use of the value of these information.Example given here is a contextual information provider with " personnel in the pit's navigation system ", is responsible for providing contextual information " A-personnel in the pit location "; With " methane monitoring system " is business service provider, registers and state a service " f=SM " of sending SMS alarm through webservice; With the wisdom service system is that core connects the two, registers and set up a wisdom service " Alarm ", and for Alarm selects situation " A-personnel in the pit location ", and business service " f=SM ".According to the needs of context-aware services logic, we increase a contextual information for Alarm, and wherein Loc-state representes the state of miner position, and Sys-state is the operating state of service system.According to the allocation models of table 1, the wisdom service system can be called business service f-SM and send SMS alarm to client worker.
Table 1 allocation models
The value of Loc-stat obtains according to the value reasoning of " A-personnel in the pit location ", and the inference rule definition is as follows:
The instance of main entity of table 2 and rule
Suppose that the wireless identification card that ore deposit A wears with oneself is rfid-A, after starting the Alarm service, the data of gathering rfid-A according to the collection period of configuration.When the normal operation of Alarm service, the Sys-state value is normal, if this miner gets into deathtrap (like loc3), is unusual through reasoning Loc-state value.The relevant context information inference that inference engine obtains is seen table 3.
The reasoning of table 3 contextual information
The Alarm business service business procedure that calls that is triggered is as follows:
The signal transceiver of some is all installed by Coal Production unit in all tunnels, particular location is decided according to field condition, is as the criterion to satisfy the location.
Coal Production unit is to producing the terminal equipment that the miner is equipped with the integrated wireless tag card, and terminal equipment is worn on the correct position of employee's wrist.The wireless identification card with inductor corresponding employee's essential information, comprise that logins such as name, age, sex, affiliated teams and groups, affiliated work post, post, my photo are in system database.
Safety in production department sticks into this wireless identification promptly comes into force after row is authorized.The scope of authority comprises: the tunnel that this employee can the qualified entering scope of operation, and the timeliness of inductor, lost efficacy, reported the loss etc., get into the tunnel to prevent unrelated person and unauthorized person.
The miner must wear the terminal equipment that the wireless identification card is housed when underground work.As this person during through the identification monitoring point in tunnel; Immediately by system identification; And the information exchange through grid; Message transmission such as the highway section that this person is passed through, time to aboveground service system record, and information can appear on geography information large-size screen monitors curtain wall simultaneously, show name through personnel.
If the wireless identification card number of induction has got into limiting channel; Service system sends to warning message on this miner's the terminal equipment automatically; Point out him to carry out associated safety work management program; On the terminal equipment display screen, provide simultaneously the gas concentration in this place, and send alarm signal to the safety monitoring center operator on duty.
