As the sight spot A of the profile rule among Fig. 4, need to gather its southeastern direction and northwest to two some c and a, wherein c and a apart from center, sight spot 5～10m, are ray ab, ad by the longitude and latitude of a, c respectively; Cb, cd then form a rectangle abcd, and abcd comprises sight spot A, and then the scope α that forms of abcd promptly is the explanation scope of A.By adjusting a, b to reasonable range, just can determine a suitable explanation scope α.When the sight spot profile is an irregular shape,, also can determine a suitable explanation model very easily as the sight spot B among Fig. 4.And this mode is determined scope, and calculated amount is little when carrying out the sight spot coupling, can alleviate the calculating pressure of processor, improves system speed.

Step 2 is obtained the longitude and the latitude information of visitor's current location, and on Memory Map dynamic drafting visitor current location point, then this content is attached on the display device; At first, as the sight spot A among Fig. 4, determine two suitable some a, c, the latitude and longitude information of gathering a, c respectively at the northeast and the southwestward at sight spot.The precision of a is designated as wLon as the west side longitude of sight spot A; The longitude of c is designated as eLon as the east side longitude of sight spot A; The latitude of a is designated as nLat as the north side latitude of sight spot A; The latitude of c is as the southern side latitude of sight spot A.And the scene data at all sight spots stored on the storer.

Step 3 is judged the scene data of visitor's current location data and storage, and whether the match is successful and the sight spot speech play marks whether to be 0, is then to forward step 4 to, otherwise forwards step 6 to; Define a structure sceneryBuffer who deposits scene data, be used for the scene data of storage is read internal memory in program run, thereby make things convenient for the coupling of sight spot scope to improve the efficient of program run.The west side longitude, east side longitude, north side latitude, southern side latitude, phonetic explaining file broadcasting time control mark and the sight spot title that comprise the sight spot in the structure.During the scene data coupling, at first the scene data of storage to be read in the internal memory.When the scene data with the position of current transfer point and storage mated, the data of reading a sight spot from file were mated, and continued to read next bar data if coupling is unsuccessful.Though saved internal memory like this, reduced system effectiveness, because the point that moves on map of the every renewal of system, the datacycle that all will carry out once all storage sight spots is mated.

Step 4 is carried out phonetic explaining; In the process of carrying out the loop-around data coupling, if the Data Matching at current transfer point and certain sight spot success (variable i was composed and was certain value this moment), illustrate that the visitor has entered the phonetic explaining scope at this sight spot, the voice document that then calls when the foreground point carries out phonetic explaining.Adopt asynchronous play, make system play voice simultaneously, continue on map, to draw the point that dynamically moves.And adopt multithreading to make system when the scene data coupling is carried out in circulation, carry out other operations simultaneously.

The step 5 phonetic explaining finishes and the speech play mark is changed to 1; For solving the phonetic explaining problem at the same sight spot of repeat playing, mark is play in one of definition in the structure of storage scene data, and is initialized as 0, just plays this phonetic explaining when the broadcast at Data Matching success and this sight spot is labeled as 0.After the phonetic explaining that plays this sight spot, immediately it is changed to 1, if at this moment the visitor is also in the explanation scope at same sight spot, even when Data Matching, the match is successful for this point, because the broadcast at this sight spot is labeled as 1, also can not carry out speech play once more.

Step 6 is pressed into the array of opening up in the internal memory with the speech play mark in proper order by visit, and content counter in the array is added 1; If but the visitor enters the explanation scope at this sight spot once more, because the broadcast mark at this sight spot has been changed to 1, so even the Data Matching success can not play this sight spot phonetic explaining yet.In order to address this problem, one of definition is pressed into the array of opening up in the internal memory in proper order by visit in structure, is used for depositing the broadcast mark at sight spot.Can adjust SIZE according to sight spot, scenic spot quantity, thereby adjust the size of array sceFlagList.SIZE is the sight spot number at scenic spot, perhaps big than sight spot quantity desired value.When the visitor entered the explanation scope at certain sight spot, corresponding phonetic explaining was carried out in the Data Matching success, and the broadcast mark with this sight spot is made as 1 then, and is pressed into the array sceFlagList that opens up in the internal memory in proper order by visit.In addition, defining one again is pressed into the array content quantity mark int curFlag that opens up in the internal memory in proper order and is initialized as 0 by visit.As each array sceFlagList[SIZE] in be pressed into after the content, array content quantity mark curFlag will add 1.

Step 7 judges that whether the content counter is then forward step 8, otherwise forwards step 2 more than or equal to 1 in the array;

Step 8 is changed to 0 with the speech play mark of the last position of currentitem in the array; Enter next sight spot at every turn and explain orally scope, finish after the phonetic explaining, remove and carry out the broadcast mark at this sight spot is made as 1, and be pressed into the array sceFlagList[SIZE that opens up in the internal memory in proper order by visit] outside the work, if this moment array content quantity mark curFlag＞=1, then with the broadcast mark sceFlagList[curFlag at this sight spot in the array] a last position sceFlagList[curFlag-1] put 0, promptly the broadcast mark at the penult sight spot just gone sight-seeing of visitor is made as 0.

The step 9 phonetic explaining finishes.

2. the tour control method of recalling module may further comprise the steps, flow process as shown in Figure 9,

Step 1, GPS positioning system are gathered the longitude of visitor's current location and the locator data of latitude;

When the visitor went sight-seeing in the scenic spot, system noted visitor's route automatically.

Step 2, extraction locator data;

Whether step 3, judgment data are extracted successful, if then forward step 4 to, otherwise forward step 1 to;

Step 4, on map, dynamically show the visitor position according to the data of extracting, and the record tour;

Step 5, visitor select the tour memory to carry out the tour memory; As long as the visitor wants to recall the route of oneself passing by, just can see own route of in the scenic spot, passing by as long as click " route memory " button;

Step 6, route are recalled end.

It mainly is that gps data with the visitor advances in the process is noted that tour is recalled, and writes in the file and preserves.Then, when route was recalled, as long as read gps data in the file, (x y), was controlled at and draws the point that dynamically moves on the map then the data of reading to be converted to the two dimensional surface coordinate.

3. the control method of scenic spot sight spot information previewing module and destination minimal path planning module may further comprise the steps, as shown in figure 10,

Steps A is opened intelligent guide system, downloads the scenic spot map and loads the scenic spot data;

Step B clicks the sight spot button control and carries out the sight spot preview;

Step C is according to oneself hobby, selects the sight spot oneself thought, and intelligent guide system is preserved the pointer of corresponding scene data;

Step D repeating step B, step C stop preview up to the visitor;

Step e is chosen at all and is used one of Floyd algorithm computation to be communicated with all by the minimal path of choosing the sight spot to form in the sight spot.

Step F is presented at the route that step e calculates on the map.

When the visitor thinks that certain sight spot is visited but when how to get to not knowing, as long as the visitor is the title or the code name at the sight spot that input will be gone, and system will plan a minimal path for the visitor automatically.

When the planning minimal path, need know the minimal path between any two point maps, system carries out the Floyd algorithm on original incidence matrix basis, obtain new incidence matrix, and in each element, increase information such as path length, forerunner's point map index newly.

The road network figure at certain sight spot of representing with the cum rights connected graph as shown in Figure 7, A～F is the point that can reach on a series of maps, and they are defined as the node of connected graph, a～g representative is communicated with the route of accessible point, they is defined as the limit of connected graph.The length of route is defined as the weights on limit.In system, the primitive relation matrix of storage is:

$\begin{array}{ccccccc}& A& B& C& D& E& F\\ A& -& -& (a,60)& -& -& -\\ B& -& -& (b,50)& -& (c,100)& -\\ C& -& -& -& (e,40)& -& -\\ D& -& -& -& -& -& (f,60)\\ E& -& -& -& -& -& (g,200)\\ F& -& -& -& -& -& -\end{array}$

(a, 60) expression can arrive the C point by pass course a from the A point, and the length of a is 60.In pathfinding, be through the square that concerns after the Floyd algorithm computation:

$\begin{array}{ccccccc}& A& B& C& D& E& F\\ A& (-,-,-)& (-,110,C)& (a,60,A)& (-,100,C)& (-,100,C)& (-,160,D)\\ B& (-,110,C)& (-,-,-)& (b,50,B)& (-,90,C)& (c,90,C)& (-,150,D)\\ C& (a,60,C)& (b,50,C)& (-,-,-)& (d,40,C)& (e,40,C)& (-,100,D)\\ D& (-,100,C)& (-,90,C)& (d,40,D)& (-,-,-)& (-,80,C)& (f,60,D)\\ E& (-,100,C)& (c,90,C)& (e,40,E)& (-,80,C)& (-,-,-)& (-,140,D)\\ F& (-,160,C)& (-,150,C)& (-,100,D)& (f,60,F)& (-,140,C)& (-,-,-)\end{array}$

Tlv triple in the formula (, 110, C) expression A point and B point not have the route that directly is communicated with, the bee-line between them is 110, need be by the indirect arrival of C point, so the bee-line between 2 be AC and CB weights with.

During pathfinding, for arriving forerunner's point map pathfinding of this route, identical with the source point map earlier between two point maps up to forerunner's point map.During from A to the F pathfinding, from the relational matrix that calculates, search the element of the capable F row of A, obtain forerunner's point map D, and then find forerunner's point map C of the capable D column element of A, find the capable C column element of A forerunner point map A at last, be source point map A, the row backward that will have access to is then arranged, and obtains A, C, D, F.Every pair of adjacent point map of this sequence all has the map road to be connected, so as long as these map roads are drawn.The capable C row of A map road is a, and the capable D row of C map road is d, and the capable F row of D map road is f.

4. wireless data interactive module

When the visitor enters the scenic spot, can open wireless data interaction function, carry out team's registration then, just can on map, see teammate's position and their situation of advancing.And on map, see a kind of color of mark of the own team member of team after the registration, the another kind of color of leader's mark.When set, meet of team leaders sends aggregate signal to the visitor, receive leader's aggregate signal as the team member after, system can be automatically for every team member of team plan a minimal path that points to the leader, the guiding visitor gathers to the leader.When the visitor follows tourist group's trip, again need not follow team to walk, be subjected to the constraint of team, the visitor can freely go sight-seeing according to the wish of oneself.As shown in figure 11, the mutual control method of wireless data is carried out according to the following steps:

Step 1 intiating radio interactive subsystem;

Step 2 is carried out team's registration;

The step 3 signal is monitored and timing;

Step 4 judges whether to take the token to teammate's broadcast position information, is then to enter step 5, otherwise returns step 3; Judge whether to receive the aggregate signal of leader's broadcasting simultaneously, be then to enter step 8, otherwise return step 3.

Step 5 is given the teammate with the broadcast of position information of oneself;

Step 6 judges whether to listen to the information that the teammate sends, and is then to enter step 7, continues to monitor otherwise return;

Step 7 is drawn teammate's position with double buffering technology;

Step 8 reads the longitude of team leader position and the data of latitude, and calculates the minimal path that points to the leader;

Step 9 is plotted in this route on the scenic spot map of guide's terminal;

Step 10 team gathers successfully;

Step 11 finishes.

Because the data interaction of wireless data interactive module is distinguished by frequency range, promptly have only between the module of same frequency and just can carry out data communication, so it is must frequency identical to want to communicate by letter.Scenic spot visitor's quantity constantly is fixing, and to send data mutually be that polling mode by token realizes.If visitor's quantity is too much, the cycle of poll will be very long, like this when showing the visitor position, and will be very not smooth.The method of problem is above solving, and will carry out team's registration when entering the scenic spot, and the guide's terminal wireless frequency in the promptly same Team Member hand will be made as identical.Simultaneously, the team leader need fill in team's number during registration, system can establish a suitable polling cycle according to team's number, then this polling cycle value is broadcast to the guide's terminal in team member's hand, guide's terminal in team member's hand can be opened a timer by real-time listening simultaneously, when having counted a polling cycle, can broadcast the once position data of oneself to all members of team.Through actual test, a little the time of painting on screen could show mobile point when being no more than 1.5 seconds glibly on map.If there are 5 people in a team, as shown in Figure 8, after registering, it is 0.3 second that system accounting is calculated the poll time cycle.

The step that the intelligent guide system method realizes, as shown in Figure 3:

Step 1 enters the start interface of guide's terminal, downloads scenic spot map and sight spot title, sight spot phonetic explaining range data, opens the GPS positioning subsystem automatically, and wherein phonetic explaining scope in sight spot is a rectangle, the vertex distance sight spot center 5～10m of rectangle; Step 2 enters the guide interface of guide's terminal, obtain the information of sight spot position data and visitor's current location longitude and latitude, and the above-mentioned data of being gathered are sent to processor, and the longitude and the latitude data of the visitor position that the GPS positioning subsystem is obtained by processor are passed through coordinate conversion, convert two-dimensional coordinate to and project on the map of scenic spot, in real time visitor's current location is presented on the map;
