Specific implementation mode
For the technology contents of technical solution, construction feature, the objects and the effects are described in detail, below in conjunction with specific
Embodiment simultaneously coordinates attached drawing to be explained in detail.
Fig. 6 is please referred to Fig.1, the present embodiment provides a kind of method for safety monitoring, this method can be applied to such as Fig. 5
In system, include the following steps：Step S101 obtains the action message of organizer's publication and uploads onto the server, the activity
Information includes the identity information of participant, activity destination, activity time；Step S102 believes according to identity information transmission activity
Participant is ceased, being associated with for participant and action message is established after participant agrees to participation activity；Step S103 participant sends out
Give the location information of itself to server, server shows participant position and movement locus according to location information on map；
Step S104 when participant causes danger, according to the location information of participant detection with the nearest organizer of participant or
Emergency contact, transmission help information to the organizer or emergency contact's.
Wherein, specifically in a certain embodiment, organizer can be by organizer end (terminal) and server into row information
Interaction, participant can carry out information exchange by participant end (terminal) and server.Terminal can be mobile phone or other
Hand-held device.Identity information is used to identify the identity of participant, such as can be social account, cell-phone number or mailbox.These
The information acquisition that information is filled in when can be registered by user when user and server are attached.The feelings caused danger
Condition can there are many, as server judges that participant is dangerous or participant oneself sends out and seeks help according to default rule
When information, it can assert that dangerous situation has occurred and that, then server obtains the position of participant and preferentially sends and asks
Supplementary information realizes when danger occurs and alarm and seeks help to nearest people.Server can also be further help information
It is sent to all organizers, emergency contact or the people for paying close attention to participant.Wherein, emergency contact can be by participant
Oneself setting.
When implementing this method, an APP (Application, application program) can be provided to organizer and ginseng
With person.Participant and organizer can also regard as in logic is concerned end and concern end.Organizer as concern end can be with
Enter establishment activity in my activity in APP, movable content, place, time, concern range are set, and are arranged one
Or multiple participants, that is, it is concerned end, while needing the agreement for being concerned end.Concern end can repair activity
Change and delete operation can show the range of concern when clicking to enter in progress or the activity not carried out on map, and
The position of all participants.When activity starts, system will automatically count the number in circle, and count without and
When reach activity venue participant, allow concern end choose whether to contact them.If some participant's individually clicked in concern end
Station location marker, system will pop up a map interface, and display is by the current location of selection participant and historical track on map.
After participant at the appointed time reaches appointed place, it can click and register, inform that concern end oneself has been arrived safely.
When being concerned end and causing danger, calling for help can be taken to operate, a key can be provided in APP and call for help module.When with
When family encounters dangerous situation, the interface that a key is called for help can be entered and click calling for help button, if instantly interface operation can not be carried out to mobile phone,
The smart key that can be arranged by system, is such as continuously called for help by power button three times.After starting calling for help, system will be adjusted
Short message, transmission email message etc. is sent with wechat public platform message interface, by cell-phone number to carry out to emergency contact list
One-to-many calling for help.If user has accidentally pressed calling for help button, there is countdown in five seconds that user is allowed to cancel formally calling for help front interface
It calls for help, avoids causing unnecessary misunderstanding.In calling for help content, can call for help text message on additional position, picture, language
The medias information such as sound, facilitates other people to get detailed information, facilitates rescue.The present embodiment by multiple channel and
Plurality of kinds of contents form is called for help, and is overcome existing application and is often only provided phone and short message two kinds of calling for help channels, calling for help information
Only include two kinds of media of text and picture, usually only to the deficiency of emergency contact's calling for help etc..Originally can be to reduce difficulty of suing and labouring
Degree improves success rate offer effectively support of suing and labouring.
Position sharing functionality can also be provided in APP.If user when walking alone at night, can open real-time position
Share, the position of oneself is shared with parent, parent is allowed to know the dynamic of oneself constantly.This when, user was exactly to be used as quilt
End is paid close attention to, parent is concern end.It is concerned and holds the object and real-time sharing for needing to select to share when open position is shared
Time span, after sharing successfully, concern end will show the current location for being concerned end of real-time update on map, with
And historical track.
This method creates the single monitoring position pattern of children under guardianship of a guardian couple of existing application
Newly, by the concept of introducing activity, concern side and the side of being concerned and the methods of multiple emergency contacts are set so that participate in work
While dynamic each user not only becomes children under guardianship by other students concern, but also the other users of concern become their monitoring
People, and then realize group guard and control；When personal safety risk occurs, the nearest concern side in Priority Call geographical location or urgent
Contact person, to realize principle emergent nearby；In addition, this is also by mobile phone, short message, wechat, mailbox, Baidu's cloud push
Get up to provide to the user personal safe protection's net with multiple platform organic integration such as application message push, and then can be
Occur to realize system interlink when safety accident.
This method also provides early warning scheme in thing.Specifically include step：Can associated participant be prejudged in work
The dynamic time terminates preceding arrival activity destination, if it could not, sending prompting message to organizer.Specifically, be concerned end or
Movable participant in carry out activity, when position data by filtering (including stagnation point filtering and drift filtering) after, be saved in
When real time position data library, early warning cloud service in thing is triggered.The service is arrived by the Mean Speed of estimation activity participant with it
Up to the air line distance of moving position, thus calculates it and reach the shortest time of moving position, if this time adds current
Between be more than the activity end time, then judge that activity participant can not reach activity venue before activity end.This disappears
Breath will be sent to movable participant and its concern side by cloud Push Service, and participant is during activity, if can not be
Place before activity end specified by arrival activity, system send warning information to each of participant concern side.To carry
The high safety of user.
Participant can sample its position data every time T and be sent to cloud server during activity.
In order to reduce wrong report, alarm efficiency is provided, we are by C (C>0) a continuous position data sampling period is as pre- in a thing
The alert period, as shown in Figure 2.Wherein：
(1)tas、taeExpression activity time started and movable end time respectively；
(2)t0At the beginning of being sampled for position data, it takes tasMaximum in the time to come into play with participant
Value；
(3) from t0Start every T time sampling once, the corresponding time interval of the secondary sampling in i-th (i >=1) is [ti-1,ti],
From t0Start to carry out early warning judgement every C sampling period.
Formula (1) provides the average speed estimated value in ith sample period.Wherein, t is indicatediThe position at moment.And dist
Function is for calculating ti-1And tiAir line distance value between moment position.
Formula (2) gives by (1) average speed, from tiThe position at moment needs the shortest time to movable designated position Pa
Estimated value tmin；
The voting results in formula (3) defined ith sample period.It is by tiIn addition tminValue and end time taePhase
Compare to determine, if cannot be in taePreceding arrival activity designated position Pa, then ballot value is 1, otherwise is 0.
Formula (4) gives tiWhether the moment pushes warning information in thing.It needs to push, it is necessary to while meeting two conditions.
First, being necessary for the integral multiple in C sampling period, another is tiIn the early warning period at place, at least collection period of half
Ballot be 1.
Early warning scheme further includes another embodiment in thing, and this method further includes following steps in the embodiment：It obtains and participates in
The location information of person；When the location information of participant is in danger zone, send prompting message to be concerned hold.Activity ginseng
Current location data is uploaded to cloud server using the application of this system with person.These data will be deposited after filtering
Real time position data library is stored up, while triggering early warning cloud service in advance.The service is by current location data and danger zone data
Data in library are contrasted, and are such as fallen in danger zone, then utilize cloud Push Service informing movement participant, movable participant
Mobile application will provide corresponding voice prompt.
Danger zone is exactly the position data in dangerous zone data library.The danger zone includes user's active
Label location at risk simultaneously uploads, the place that user is called for help or the location at risk that network crawls.Specifically include following three
Aspect：When user usually live in see accident occur can active flag place be uploaded to system background, second is that user
Carrying out the place of a key calling for help will also be recorded, and be the key data source in this system risk data library in terms of third,
Data are obtained from internet by technologies such as natural language processing, data minings.
The danger zone that the network crawls is obtained according to following steps, as shown in Figure 3：A default URL is (unified
Resource Locator, Uniform Resource Locator) initial queue；One is selected from URL queues not to be accessed
URLi；It captures corresponding webpage on the internet according to URLi, URL is extracted from webpage, and they are joined the team to URL queues
In；Character string to meeting preset condition on webpage is segmented the information that safety accident was occurred, and then passes through filtering
Obtain dangerous place name；Address lookup is carried out to obtained dangerous place name, and then the longitude and latitude of location at risk can be acquired, it should
Longitude and latitude is danger zone.Specifically, it can be achieved by the steps of：
Step1：Seed URL joins the team to form URL initial queues.Seed URL can choose closely related safely with university student
Website, blog or forum；
Step2：The Step7 if queue is dallied, otherwise turns Step3；
Step3：Go out one URLi of team from URL queues to turn Step4 if the URLi is not accessed, otherwise turn Step2；
Step4：Capture corresponding webpage pagei on the internet according to URLi.URL is extracted from pagei pages, and will
They join the team into URL queues；
Step5：The information that safety accident was occurred is segmented to pagei pages of upper qualified character string, so
Afterwards by being obtained by filtration dangerous place name, detailed description are as follows that internet address of the text based on template matches excavates by Step5；
Step6：Place name is obtained to Step5 by Baidu API and carries out address lookup, and then location at risk can be acquired
Longitude and latitude；
Step7：Terminate the process crawled.Network in this way crawls can get danger zone automatically, convenient pair
User location carries out early warning.
Extract address in the existing simple sentence from text and sentence can be compared with the address in better address library thus
Address is extracted, on the other hand the very detailed and huge address base of this method one side needs is existing address base by address
Partition of the level efficiency when address compares and inquires is greatly reduced, therefore is difficult to apply in actual system.The danger of the present invention
The acquisition of place name can be excavated by the internet address based on template matches.I.e. step on webpage " to meeting preset condition
Character string is segmented the information that safety accident was occurred, then by the way that dangerous place name is obtained by filtration " include following step
Suddenly：
After being segmented from web page crawl text and to it, the word in accident keywords database is determined whether, if it is determined that success
Match forming keyword sequence to be matched with address keyword library again, then carries out template matches with template library again, if
It fails to match abandons this section of content and carries out the operation of next section of content, and successful match is then according to the extracting rule of each template
Extract the address in content.
Specifically, as shown in figure 4, this system by being segmented from web page crawl text and to it after, be determined with impunity
Therefore the word in keywords database, if it is determined that success match forming keyword sequence to be matched with address keyword library again, so
Afterwards again with template library carry out template matches, abandon this section of content if it fails to match and carry out the operation of next section of content, matching at
Work(then extracts the address in content according to the extracting rule of each template.During wherein Words partition system is calculated using the Chinese Academy of Sciences
The Chinese lexical analysis system ICTCLAS of heart research institute.
A. accident keywords database mark and matching
Dangerous address base need to be built according to this system demand, the address in address base will be with related, the institute that has an accident
Be exactly first critical point for extracting address contents with accident keywords database, come judge web page crawl to content whether belong to thing
Therefore information.
Vocabulary in accident keywords database is labeled as a spcial character after participle, such as " OK ", accident keyword
The structure in library namely adds user-oriented dictionary (can hereafter introduce user-oriented dictionary function), so judging when accident dictionary matches
Being labeled with after participle does not have " OK " this mark, does not enter next section of content then, and successful match then enters address keyword
Label, example such as following table accident dictionary matching citing.
Table：The matching citing of accident dictionary
Will be described below how building accident keywords database.The structure of accident keywords database be in the training text stage,
Can be found from network in training multistage and accident generation in relation to and the news report containing better address, before this manually into
Rower note and one by one typing accident keywords database, such as：It plunders, be crushed to death, murdering, being killed, traffic accident etc., then according to existing word
It converges and searches for its synonym with third party's interface to expand dictionary.In addition, also having another scheme, the pass that typing manually marks
After keyword, just the vocabulary after participle is counted one by one with the word in accident keywords database in test module stage every once segment
Calculating Lexical Similarity, (reference is based on《Hownet》Lexical Similarity calculate) expand dictionary.
B. address keyword classification and label
Address keyword refer to relevant with address contents or the set of vocabulary that identifies containing address for example province, city,
Area, street, turn left etc., the effect of keyword be when segmenting again to original web page crawl content key vocabularies carry out it is privately owned
Mark, while building template library in the training text stage.
1. address keyword is classified
ICTCLAS (also known as NLPIR) major function includes Chinese word segmentation, part-of-speech tagging, name Entity recognition, user's word
Allusion quotation function etc., is a quickly and accurately Words partition system, its participle part of speech is more than 20 kinds.In view of this system demand and
Simplify template number, verb, noun, preposition, four kinds of punctuation mark can be classified as, in addition newly adds user-oriented dictionary to increase
Type is segmented, this is also the reason of address keyword library is established.
User-oriented dictionary in so-called address keyword library i.e. ICTCLAS systems, can be according to user when system segments
Dictionary, that is, address keyword library exists mark participle such as " Fuzhou City " this word that the vocabulary in user-oriented dictionary is specified according to user
Character string when not adding user-oriented dictionary after participle is " Fu Zhoushi n ", according to the vocabulary classification in dictionary after addition after addition
It is segmented and is labeled as " Fuzhou City B ".Vocabulary in present address keywords database is divided into 4 classes：
Class A. indicates the vocabulary of provincial place name or word (such as：Province, Jiangsu, Fujian, Guangdong, Zhejiang etc.)
The vocabulary of class B. expression city-level place names or word is (such as：City, Wuxi, Shenzhen, Foochow, Hangzhou etc.)
Class C. indicates the vocabulary of area, grade place name at county level or word (such as：Area, county, Minhou, Chong An, Cang Shan etc.)
Class D. is indicated with the relevant vocabulary of address contents (such as：Town, street, crossing, square, main road, road etc.)
Vocabulary in address keyword library is divided into this 4 class by the present embodiment, is unlikely to so that database is excessively complicated.
2. address keyword marks
In address keyword marking phase, system is segmented according to the classification in the keywords database of address with part of speech again
Label, and by ICTCLAS original part of speech label merger be verb v, noun n, preposition p, punctuation mark (wd, wj),
It is not marked if being surveyed without this three classes and newly added 4 class vocabulary.Address keyword label forms label sequence after completing
At this moment row carry out template matches with the template in flag sequence and template library, are carried according to the extracting rule of this template after being matched to
Take address contents, example such as following table：Address keyword label citing.According to the template being matched in table：The rule of BCDwdOKwj
Then extraction is marked as/character string between B and/D vocabulary, therefore it is Fuzhou City Cangshan District Shang Duyong brightness supermarket to extract content
Mouthful.
Table：Address keyword label citing
C. template library is established formulates with extracting rule
In the training text stage, we establish a template library, and each template has its corresponding extraction rule
Then.This is similar with the foundation of accident keywords database, and the multistage found using internet is related with accident generation again containing in detail
The news report of location as training text, according to above-mentioned 4 class newly add keyword (A, B, C, D) with the original mark of word segmentation of 4 classes
(verb v, noun n, preposition p, punctuation mark (wd, wj)) excavate its Frequent episodes, while obtaining Frequent episodes conduct
Template input template library, detailed process such as Fig. 5 template trainings flow.
After having the template in template library, need to formulate a set of extracting rule for each template, extracting rule is：A or B
Class word starts (including A or B) to punctuation mark or first verb and terminates.After operation above, so that it may to get
The address of extraction.
The acquisition of location information can be realized by GPS in above-described embodiment.But in terms of fix drift, according to GPS
Positioning principle, applies to reality, and several factors can all influence the positioning accuracy of GPS.First, object activity speed is too fast, with
The response time in GPS is caused to be shorter than present speed；Second, in the bad place of up to building dense or weather condition, GPS letters
Number process causes signal errors to this folding, reflection.Therefore the interference in short distance to GPS signal is on the one hand reduced；It is another
Aspect needs to be filtered drift, i.e., crosses filter data when location information exceeds the radius of road, and according to last time
Speed and direction calculate the position of current point.In navigation software by coordinate setting within road, if what GPS was received
Signal exceeds the radius of road by automatic fitration data, and the position of current point is calculated according to the speed of last time and direction.
It is this frequent in a small range because the tracing point of object can change because of its movable position in terms of the filtering of stagnation point
Track data acquisition will increase the workload of server end.Therefore, it is necessary to stagnation points to be filtered, i.e., will exist for a long time
Movable location information in a certain range is set as fixed point.System by object for a long time in a certain range of activity,
It is set as fixed point, other stagnation points is filtered using the algorithm of setting, keeps the display of map track relatively sharp, orderly.
When user is no outside mobile, system can filter out the stagnation point of repetition by algorithm, be replaced with a current latest position
In generation, this can substantially reduce the burden of system, be avoided data redundancy.Position information process keeps the positioning of this method more accurate,
The guarantee of safety is more in place.
As shown in fig. 6, the present invention also provides a kind of safety monitoring system 600, including organizer's terminal 602, server
604 and participant's terminal 605；
Organizer's terminal is used to obtain the action message of organizer's publication and uploads onto the server, the action message packet
Include the identity information of participant, movable destination, activity time；
Server is used to send action message to participant according to identity information, is built after participant agrees to participation activity
Vertical participant is associated with action message；
Participant's terminal sends the location information of itself to server for participant, and server according to position for believing
