Floatdistance=AMapUtils.calculateLineDistance (startLatlng, endLatLng), calculate the distance of the warning center coordinate that current location is marked and arranged, the numerical value unit that its method returns is m, the judgement of size is directly carried out with the early warning radius r adius arranged, before contrast, application is provided with zone bit, judge whether to send note by zone bit, set the condition sending note and send as just holding to monitoring when being carried out action transboundary by guardianship.
The function of carrying out due to each Activity in performance history is different, some Activity have modified some as parameters such as binding state, network monitoring states, this just needs to carry out the communication between Activity, because Activity is numerous, so the trouble that communication is got up very, in order to address this problem, apply global variable AppData class in this application, its life cycle is consistent with whole application, can't once which Activity just disappears along with the destruction of Activity after destroying as common data class.Therefore use AppData class to preserve some state variables and read that binding information completes the initialization operation of binding information and global data account, password etc. as whether from server.
The realization of AppData: AppData be realized and first should write a data class, the data type that various needs are used is write in the inside, then to these data types encapsulation getter and setter, again this data class is inherited Application class, after succession, open configuration file AndroidManifest.xml, add in application attribute:
android:name=“com.lxylbs.data.AppData”
Wherein com.lxylbs.data.AppData is the position of just now write data class, complete writing of global variable class, next be just the use of, instantiation AppData object during use, as AppdatamAppData, again to this object initialization, mAppData=(Appdata) context.getApplicationContext (), getter and setter then calling mAppData carries out the operation to data.In application, a lot of local network of all using goes to access long-range data, and due to the uncertainty of network, the time that some data arrive is uncertain, so the acquisition of teledata can not be synchronous with the use of data, must go access with asynchronous thread.In prior art, conventional Handle mechanism goes to process these events, but the use of Handle must import a Handle object into, and using not is facilitate very much, so the present invention uses broadcast mechanism to address this problem.The result of operated from a distance database is sent with the forms of broadcasting, which Activity needs to accept this broadcast, only need add broadcast filtering device in Activity, register this to broadcast, when but which Activity with which Activyty registers, using each time all must instantiation BroadcastReceiver object, and does method of reseptance process to its reception, and code maintenance gets up and inconvenient completely.Therefore, a BaseActivity base class has been write in the present invention.
Therefore the functional realiey of described monitoring end comprises the following steps: step one: write a data class, this data class comprises the data type that needs are used, then to these data types encapsulation getter and setter, again this data class is inherited Application class, after succession, open configuration file AndroidManifest.xml, add in application attribute: android:name=" com.lxylbs.data.AppData ", wherein com.lxylbs.data.AppData is the position of described data class, instantiation AppData object during use, AppdatamAppData, again to this object initialization, mAppData=(Appdata) context.getApplicationContext (), getter and setter then calling mAppData carries out the operation to data, step 2: write a BaseActivity base class, this base class is claimed as abstract base class, the broadcast that whole application can use is have registered in base class, only write Action, the stringExtra of onReceive method to the broadcast received in class to judge, and in conjunction with above-mentioned global variable class, storage operation being carried out to data, which Activity uses broadcast only need inherit this base class, it is sendMsg (Stringmsg) that this base class comprises an abstract method, change method to realize carrying out operational processes to the UI of other activity, msg parameter is the result after process data, operate UI in sendMsg, the implementing reading and writing of global variable class AppData being carried out to data is called Activity's, step 3: open WelcomeAcivity, it carries out the initialization operation of database, by the ConnectionChangeReceiver broadcast listening network change in BaseActivity, without not operating database during network and ejecting Toast message informing user, network is unavailable, and WelcomeActivity uses the time delay of Handle mechanism within five seconds, automatically to jump to LoginActivity afterwards to carry out user and log in, step 4: log in and successfully enter HomeActivity afterwards, HomeActivity is the entrance being arranged each function by guardianship location, early warning, binding machine, facility information is held in being guarded of direct this account of the described database request binding of HomeActivity, stored in global variable Appdata, and the IsBind state in global variable class is arranged to TRUE, step 5: enter binding function BindActivity, apply after entering this Activity first go to obtain this account binding in global variable by the information of guardianship, information does not exist, then show on the page, without bound device, if there is bound device information, then facility information is shown, the pet name is filled in when need revise binding number, the device number of bound object is submitted to, the device number of input after submitting to inquires about whether there is this equipment in db_child_info table, if this equipment exists, then by remote data base db_myuser show in this account to bindneme, the data that during binddevice write binding, defeated user inserts, and upgrade the device object of the current new binding of UI display, the IsBind of global variable is arranged to TRU simultaneously, step 6: enter location LocationActivity, this Ativity and be divided into two patterns, guarded end station-keeping mode for one, another is for checking historical track pattern, held in station-keeping mode by monitoring, use Handler.postDelayed (this, 10000), in runnable, again transfer the method goes acquisition teledata to be guarded the positional information of end simultaneously, realize by the real-time update of guardianship, after obtaining position, the Marker method using Amap to provide draws coordinate on map, picture seat calibration method is packaged into a function and is fallen by the marker drawn before mark Remove when function call, and a map interface would not be caused like this to occur, and the phenomenon of a lot of marker occurs, in the pattern of checking historical track, monitoring end goes to obtain the location_path by monitoring end, re-using the url obtained goes access to obtain file, read the Arraylist of Study document acquisition with history coordinate, the type wherein deposited in Arraylist is Latlng, ArrayList<LatLng>, after getting out history coordinate, in map, use AMap.addPolyline (PolylineOptions) to carry out drafting broken line, polylioneOptions object can arrange line thickness, color, the Latlng coordinate drawn, direct use PolylineOptions.addall (Arraylist<latlng>) puts into coordinate set, step 7: enter warning function, first carry out initialization interface operation, MapView does the display of map interface, monitoring end first in server request bound device tables of data alarmlocation and radius parameter, if parameter is not empty, then coordinate centered by alarmlocation, radius is the early warning range that radius draws bound equipment, if be sky, does not process, the central point of map is set to the position of current guardian: use LocationManagerProxy, calls this object
RequestLocationData (LocationProviderProxy.AMapNetwork, 60*1000,15, this), the wherein type of first Parametric Representation location, here be mixed positioning, use gps data when gps data preferentially returns, use LBS data when LBS high priority data returns, then use gps data when returning simultaneously, second parameter is the interval at every turn obtaining position, and the 3rd parameter is mobile 15 meters, obtains positional information; After calling, write subsequent operation at the onLocationChanged that must rewrite, directly revise map center point here and draw marker; The acquisition of warning function central point: click event is arranged to Amap and monitors: aMap.setOnMapClickListener (); After clicking, we cause Latlng and directly do clicking the coordinate obtained on map interface and show, and input radius, during submission, by bound device corresponding in set value update to db_child_info in Editext simultaneously.Fig. 3 inquires about for monitoring end and is guarded end position functional schematic see Fig. 3.Monitoring end arranges early warning range schematic diagram see Fig. 4.

Step 7: enter warning function, first carry out initialization interface operation, MapView does the display of map interface, monitoring end first in server request bound device tables of data alarmlocation and radius parameter, if parameter is not empty, then coordinate centered by alarmlocation, radius is the early warning range that radius draws bound equipment, if be sky, does not process;
The central point of map is set to the position of current guardian: use LocationManagerProxy, call the requestLocationData (LocationProviderProxy.AMapNetwork of this object, 60*1000, 15, this), the wherein type of first Parametric Representation location, here be mixed positioning, gps data is used when gps data preferentially returns, LBS data are used when LBS high priority data returns, then use gps data when returning simultaneously, second parameter is the interval at every turn obtaining position, 3rd parameter is mobile 15 meters, obtain positional information, after calling, write subsequent operation at the onLocationChanged that must rewrite, directly revise map center point here and draw marker,
The acquisition of warning function central point: click event is arranged to Amap and monitors: aMap.setOnMapClickListener (); After clicking, we cause Latlng and directly do clicking the coordinate obtained on map interface and show, and input radius, during submission, by bound device corresponding in set value update to db_child_info in Editext simultaneously.
4. the long distance monitoring warning system based on Android platform according to claim 2, it is characterized in that: the described functional realiey by monitoring end comprises the following steps: after soliciting user's agreement, the device number of end is guarded in direct acquisition, be updated to by the database of monitoring end, open Service service, with background server exchange data information simultaneously; Service service sends ownship position information to server database in every 5 seconds, the positional information sent comprises the latitude and longitude coordinates location of location updating time Uloadtime and position, every five points of clockwise server databases send the location.txt document comprising historical position information, and embedded positional information form is consistent with the information format being sent to database;
While transmission positional information, judge that whether this be empty by the value of guarding equipment id alarmlocat and radius in db_child_info corresponding to end, not for sky then obtains data stored in application global variable, re-use Floatdistance=AMapUtils.calculateLineDistance (startLatlng, endLatLng), calculate the distance of the warning center coordinate that current location is marked and arranged, the numerical value unit that its method returns is m, the judgement of size is directly carried out with the early warning radius r adius arranged, before contrast, application is provided with zone bit, judge whether to send note by zone bit, set the condition sending note to send as just holding to monitoring when being carried out action transboundary by guardianship.
5. the long distance monitoring warning system based on Android platform according to claim 3 or 4, it is characterized in that: the map used is high moral map, the application of high moral map comprises the following steps: initial landing high moral LBS open platform: http://lbs.amap.com/, is registered as developer; After logging in, enter control desk interface and obtain key, ejecting the title inputting Mobile solution in interface, the AndoridSDK of the service of the high moral map of choice for use, in bag name option, insert the bag name of application, described bag name must be consistent with the bag name in AndroidManifest.xml configuration file in Mobile solution engineering; In security code one hurdle, insert SHA1 value, its obtain manner for select WINDOW menu in eclipse, and Preferances option in choice menus, clicks the Build item of andorid and can check and obtain key; Afterwards, equally again open application project AndroidManifest.xml configuration file, in application, add attribute:
<meta-dataandroid:name="com.amap.api.v2.apikey"
android:value="6e1ac06c9482f57bf61592e2e79a1ffa"/>；
Wherein the value of value is applied for key.
