The vehicle communicator 17 of forming a team is used for forming a team to communicate by letter with other navigational system.
Exist now the driver's steering vehicle separately more than two or two usually, form a team to make an appointment and go to the situation of same destination.Because traffic lights is many on the road, situations such as driving vehicle is many, road conditions complexity exist, and fleet usually can be broken up mutually, need ceaselessly to connect each other by electronic equipments such as mobile phone, intercoms, form a team with recovery, move ahead jointly.The mode work efficiency of this communication contact is lower, especially in the fleet vehicle fleet size more for a long time, the situation that usually causes confusion, the mechanism paralysis of forming a team.
State Intellectual Property Office of the People's Republic of China's patented claim: " control method of motor vehicle formation driving system " (open day: on June 6th, 2007; Application number: 200610098026.X; Be designated hereinafter simply as documents 1), a kind of control method of motor vehicle formation driving system is disclosed, wherein, in the fleet of two above member compositions, the mutual communication of each member's onboard navigation system also constitutes a network, and the software control of this communication network is made up of following four mechanism:
The formation set-up mechanism: with a certain member is the team leader, as another member when the team leader sends the application of add forming into columns, the team leader can make acceptance, two kinds of selections of refusal, if the team leader makes the acceptance selection, then create to form into columns and obtain administration authority, comprise startup, termination, setup parameter, accept the team member, the refusal team member, play except that the team member to forming into columns;
Formation member position message mechanism: formation member is periodically to team leader's information that reports in, and by sending to next formation member behind team leader's tissue, until sending to all formation member places;
Formation message transmit mechanism: formation member can be selected to send announcement message or whisper with some members;
Formation termination mechanism: when the formation time that the team leader sets then stops or by team leader's active termination.In the disclosed technical scheme of documents 1, adopt the mode of GPRS communication to send positional information mutually and get in touch, can avoid manual contact and cause the low problem of communication efficiency.But, on average share though the announcement message that sends in the middle of the formation member can force to carry out expense by the policy of operator, but other point-to-point GPRS communication remains the specific aim charge.Especially in fleet, especially in formation member position message mechanism, each team member only need give team leader's report position information, and the team leader needs to send information to all team members, and team leader's communication fee is apparently higher than other vehicles.Carry out the way that expense is shared out equally as for the GPRS communication of passing through alleged in the documents 1, that is not that design by technical scheme realizes, but the policy realization by specific operator, be subjected to the restriction of operator.
In addition, though the team member of fleet can receive the member's of fleet that the team leader sends positional information, if the vehicle that has in forming a team only thinks that and then team leader's vehicle is walked, so, personnel ceaselessly carry out the path setting with team leader's vehicle location as the destination with regard to needs in this vehicle, and operation is trouble comparatively.
Use GPRS to make communication modes in the documents 1,, because the GPRS communication modes depends on the network condition situation, adopt point-to-point ground of GPRS sent-received message to have great limitation, this type of point-to-point GPRS communication can not be supported, be realized to the telephone network of a lot of local operators smoothly.And the communication cost of GPRS is also transparent inadequately usually, and the user can not just can clearly predict the definite charge situation of next the bar information of transmission before transmission information.
In sum, the form into columns control means of communication of travelling of existing GPS navigation system exist communication cost and share extremely unbalancedly, and the team leader is the communications cost problem of higher that the founder of fleet need bear.
Summary of the invention
For overcoming above-mentioned defective, technical matters to be solved by this invention provides the vehicle that uses in the lower navigational system of communications cost that a kind of founder of fleet need the bear communication means of forming a team, and the vehicle that uses in the navigational system the form a team founder of fleet use side and team member's use side of communicator.
The objective of the invention is to be achieved through the following technical solutions:
The vehicle that uses in a kind of navigational system communication means of forming a team comprises fleet's constructive process and fleet's communication process, and wherein, described fleet constructive process may further comprise the steps:
A: acquisition will add the team member who forms a team;
B: according to default foundation rule, creating artificial root with fleet and set up the information forwarding tree, is the team member's distribution locations in the information forwarding tree that adds, and this team member of upper level team member of the team member of notice adding is set to the next stage team member of forwarding information; In the described information forwarding tree, among the founder's of fleet the next stage team member, have at least a team member to have the next stage team member of self;
Described fleet communication process may further comprise the steps:
C: the next stage team member related with it that the founder of fleet puts down in writing in the information forwarding tree sends information;
D: after current team member received the information of upper level team member transmission, the next stage team member related with it who puts down in writing in the information forwarding tree transmitted this information;
E: repeating step D, all team members that put down in writing in current forwarding tree have received above-mentioned information.
Setting up rule described in the step B is: in the current information forwarding tree, the team member of the information minimum number that selection sends when adding fleet altogether, or the team member of the ratio minimum of the information of transmission number and adding fleet duration is as the team member's of current adding upper level team member.
In the described information forwarding tree, the next stage team member who is associated with the founder of fleet only has one.Because the founder of fleet is except the positional information at the current location place that will send the leader of a group of people people who has put down in writing current fleet, also needing directly to send the information of forming a team forms a team to specific team member, such design can alleviate the quantity that the founder of fleet need send positional information, the extra information of forming a team that sends of quasi-complement guarantees the information number that average founder and other team members send from macroscopic view.
In the described information forwarding tree, the team member except that the founder of fleet is interrelated according to the structure with binary tree, and wherein, that next stage team member who is associated with the founder of fleet is as the root node of binary tree;
Accordingly, setting up rule described in the step B is: in the next stage team member's of association number is less than two team member, select a team member arbitrarily, or select the team member of the information minimum number that when adding fleet, sends altogether, or select the upper level team member of the team member of transmission information number and the ratio minimum that adds fleet's duration as the team member of current adding.
In the described fleet constructive process, after also being included in the automatic rearrangement condition that has reached default, the default reordering rule of position basis to the team member place in the current information forwarding tree, again create artificial root with fleet and set up the information forwarding tree, be the team member's distribution locations in the information forwarding tree that adds, and this team member of upper level team member of the team member of notice adding is set to the next stage team member's of forwarding information step.Such design is at the bottom of those accumulative total forwarding information a fairly large number of team members being reduced to the tree of information forwarding tree, reduces the information hop count of its next stage.
Described reordering rule is: calculate the information number that the team member except that the founder of fleet sends when adding fleet altogether, the people is set up the closer to fleet in the position of people in the information forwarding tree that the information number is few more; The people is set up away from fleet more in the position of people in the information forwarding tree that the information number is many more;
Or be: the team member who calculates except that the founder of fleet sends information number and the ratio that adds fleet's duration, and the people is set up the closer to fleet in the position of people in the information forwarding tree that ratio is more little; The people is set up away from fleet more in the position of people in the information forwarding tree that ratio is big more.
In the described fleet communication process, between the team member, send information by short message mode.When promptly sending information, adopt the mode of short message service (Short Messaging Service is abbreviated as SMS) to send.
Described information is the leader of a group of people people's of current fleet the positional information at current location place, among the described step D, receive the position note of upper level team member transmission the team member after, comprise also note resolved that the leader of a group of people people's who puts down in writing in the note current location is set to the step of the destination of navigational system.
The form a team founder of the fleet use side of communicator of the vehicle that uses in a kind of navigational system, it comprises: the team member adds submodule, information forwarding tree creation module and information sending module,
Described team member adds submodule, is used to obtain to add the team member who forms a team, and gives relevant team member with the information feedback of forming a team that information forwarding tree creation module generates;
Described information forwarding tree creation module, be used for according to setting up rule, with the current vehicle communicator of forming a team is that root is set up the information forwarding tree, for add vehicle that the team member that obtains the submodule the uses communicator distribution locations in the information forwarding tree of forming a team from the team member, generates the information of forming a team;
Described information sending module is used for the next stage vehicle that information sends to the information forwarding tree communicator of forming a team.
Form a team team member's use side of communicator of the vehicle that uses in a kind of navigational system, it comprises:
Information receiving module is used to be received in the information that other team members send;
Next stage team member relating module is used for the associating information next stage team member that forms a team who sends according to the founder of fleet;
Information forwarding module, the information that the upper level team member who is used for receiving sends is transmitted to the next stage team member related with it.
Because in the information forwarding tree of setting up, in the founder's of fleet the next stage team member, have at least a team member to have the next stage team member of self, the founder of fleet makes when need send to each team member with information, only need earlier information to be sent to the next stage team member of the founder of fleet in the information forwarding tree, again by the next stage team member forwarding information of its next stage team member to himself, make some team members can substitute the communications cost that the founder of fleet bears a part, reach the purpose that reduces the communications cost that the founder of fleet need bear.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
Because smart mobile phone popularizes now, smart mobile phone can be accomplished one of staff already, the mobile navigation system that operates in now on the smart mobile phone is also very many, in order better to guarantee the communication quality between the navigational system, the expense that clearer and more definite calculating retransmission of information produces, the present invention's employing sends SMS (Short Messaging Service) way of short messages and realizes the communication between each navigational system in each smart mobile phone.Certainly, the technical scheme described in the present invention still can adopt other communication form.
In order to reduce the communications cost that the founder of fleet need bear, make the expense that each team member bore of fleet average, navigational system of the present invention has adopted the following vehicle communication means of forming a team, and it comprises fleet's constructive process and fleet's communication process.In the present embodiment, the team leader is the founder of fleet.
Fleet's constructive process may further comprise the steps:
A: acquisition will add the team member who forms a team;
B: according to default foundation rule, creating artificial root with fleet and set up the information forwarding tree, is the team member's distribution locations in the information forwarding tree that adds, and this team member of upper level team member of the team member of notice adding is set to the next stage team member of forwarding information; In the described information forwarding tree, among the founder's of fleet the next stage team member, have at least a team member to have the next stage team member of self.
Wherein, the foundation rule is: in the current information forwarding tree, in the next stage team member's of association number is less than two team member, select a team member arbitrarily, or select the team member of the information minimum number that when adding fleet, sends altogether, or select the upper level team member of the team member of transmission information number and the ratio minimum that adds fleet's duration as the team member of current adding.Team member except that the founder of fleet is interrelated according to the structure with binary tree, and wherein, that next stage team member who is associated with the founder of fleet is as the root node of binary tree.The process of setting up the information forwarding tree is as follows: with 1 team member as the founder's of fleet next stage team member (be referred to as one-level roll off the production line team member).In this one-level rolls off the production line the team member, from the team that does not join tree as yet, get two team members again among the team member as the secondary team member of rolling off the production line.The rest may be inferred in other team member's of rolling off the production line of other grades adding, all is added in this tree up to all team members.Fig. 2 shows the structure of the formed tree of being made up of 10 team members of fleet.This tree below is referred to as " information forwarding tree ".
The present invention adopts the primary structure of the structure of binary tree as the information forwarding tree, be because team member's quantity can be not too many in the common fleet, the height of binary tree can be too not high, the team member that note arrives minimum one-level does not need to experience the long time, can satisfy people's use generally.Same, when too much, can increase the number of the next stage team member of each upper level team member association in the information forwarding tree as one sees fit, as adopting the structure of ternary tree as if the quantity of team member in the current fleet; Can also adopt the structure of some special trees, as adopting the only corresponding formation form that rolls off the production line of reaching the standard grade.
The team leader is when setting up the information forwarding tree, the telephone number that provides when applying for adding fleet according to the team member, team member in the fleet is arranged the position in advance earlier, need related next stage team member's team member to send out the next stage team member's that he should be related telephone number in the pre-queuing each by above-mentioned foundation rule.The mobile phone that each team member uses then carries out related with next stage team member's phone number as receiving next stage team member's telephone number.
The team leader can be after the default automatic rearrangement time interval, for example 2 hours once, reset position to the team member place in the information forwarding tree, the starting point of mainly considering during rearrangement be those accumulative total forwarding information a fairly large number of team members are reduced to the tree of information forwarding tree at the bottom of, reduce the information hop count of its next stage.Reordering rule is as follows: calculate the information number that the team member sends when adding fleet altogether, the people is set up the closer to fleet in the position of people in the information forwarding tree that the information number is few more; The people is set up away from fleet more in the position of people in the information forwarding tree that the information number is many more; Also can adopt other reordering rule, send information number and the ratio that adds fleet's duration as calculating the team member, the people is set up the closer to fleet in the position of people in the information forwarding tree that ratio is more little; The people is set up away from fleet more in the position of people in the information forwarding tree that ratio is big more.Notice that the foundation rule that reordering rule should be when setting up the information forwarding tree is consistent.
Owing to only a team member is issued in the position of oneself when the team leader has just begun, therefore, other send the team member of note to two next stage team members relatively, and team leader's transmission note number of times is less.Like this, though the team leader when queue and rearrangement because notifying all team members more multiple notes, but in general, in whole the forming a team, each team member's note sends number can reach balance.
As shown in Figure 3, the founder of fleet to ratify the process that the team member joins the team as follows:
Step S101: the application note of joining the team of waiting for, receive the team member;
Step S102: judge that the team leader accepts or this application of joining the team of refusing to unite by interactive interface; If accept, carry out rapid S104, if team leader's refusal, execution in step S103;
Step S103: send the application team member and be rejected the short message of joining the team, return step S101 and continue to carry out to the application team member;
Step S104: this team member is added fleet, write down the moment that this team member adds fleet, the forwarding number that this team member is set is 0;
Step S105: send application and join the team successful information to the application team member;
Step S106: be application team member distribution locations in " information forwarding tree ": as, can in the team member who does not also overwork two players whose turn comes next, select and send note number and the less team member of ratio who adds fleet's duration, wherein, this team member's adding fleet duration is that this team member of obtaining of record adds fleet constantly and the time span between the present time in the step 104;
Step S107: whether the upper level team member who judges this team member is team leader oneself; In this way, return execution in step S101, otherwise execution in step S108;
Step S108: notify this team member's upper level team member, make its team leader's that will in follow-up time, receive position note be transmitted to this team member, return step S101 and continue to carry out.
Fig. 4 shows the flow process that team member's application is joined the team, and may further comprise the steps:
Step S201 receives team leader's phone number that the user imports;
Step S202, the application that the receives user's input instruction of joining the team;
Step S203 sends the application of forming a team;
Step S204 receives the feedback information of forming a team to apply for;
Does step S205 judge that according to feedback information the team leader accepts this application of joining the team? in this way, execution in step S205 is as denying the end process flow process;
Step S206 enters the state of forming a team.
Fig. 5 shows the processing procedure that the team leader resets the information forwarding tree, may further comprise the steps:
Step S301 judges whether to satisfy default automatic rearrangement condition, needs to reset " the information forwarding tree " structure? in this way, execution in step S302, otherwise return execution in step S301; Wherein, reset once every two hours in the present embodiment, therefore, the automatic rearrangement condition of the judgement of this step is exactly the time span of the time of resetting present time and last time or form a team the establishment time (it is out-of-date never to reset), whether reaches two hours;
Step S302, the information forwarding tree is rearranged, wherein, the foundation that rearranges is, each team member except that the team leader calculates the ratio of the time of its forwarding short message bar number and adding fleet, sorts according to ratio, filling mode by complete binary tree carries out the filling information forwarding tree then, and the next stage team member of tree root as the team leader;
Step S303 notifies each team member to cancel former forwarding next stage team member, and new forwarding next stage team member is set.
In whole vehicle is formed a team communication process, can be by automatically resetting the number of adjusting the note that each team member transmits, reduce the bar that sends note between each team member and count poorly, reached the purpose of the communications cost of average each team member's communication from macroscopic view.
As shown in Figure 6, current team member that its next stage team member's treatment scheme is set is as follows:
Step S401 judges whether current team member receives cancellation or next stage team member's instruction note is set, in this way, and execution in step S402 then, otherwise return execution in step S401;
Step S402 according to indication information cancellation or the next stage team member who needs forwarding short message is set, returns execution in step S401.
After the information forwarding tree had been finished in foundation, the founder of fleet can send note to all team members very easily.Wherein, fleet's communication process may further comprise the steps:
C: the next stage team member related with it that the founder of fleet puts down in writing in the information forwarding tree sends information;
D: after current team member received the information of upper level team member transmission, the next stage team member related with it who puts down in writing in the information forwarding tree transmitted this information;
E: repeating step D, all team members that put down in writing in current forwarding tree have received above-mentioned information.
For fleet founder position is followed in the navigation of each team member in realizing forming a team automatically, the founder of fleet periodically (for example 1 minute once) sends way of short messages to other members; After other-end is arranged on and receives fleet founder position, carry out the path with fleet founder position as the destination automatically and rerun, thereby realize that following the founder of fleet automatically navigates.
As shown in Figure 7, the team leader to send the treatment scheme of position note as follows:
Step S501, team leader judge whether to need to send positional information, and in this way, the position at record team leader's current location place generates positional information, carry out poly-S502 of step, otherwise return execution in step S501;
Step S502 judges whether the team leader has the next stage team member, in this way, and execution in step S503, otherwise return execution in step S501;
Step S503 sends the next stage team member of positional information to the team leader;
Step S504 adds 1 to the team member's who needs forwarding short message in the information forwarding tree the number of posting a letter.
As shown in Figure 8, the team member carries out following steps after receiving the note that the team leader sends:
Step S601 receives the positional information that the team leader sends;
Step S602 judges whether current team member has the next stage team member; In this way, execution in step S603 continues to carry out otherwise forward S604 to;
Step S603 transmits team leader's positional information and gives the next stage team member;
Step S604 resolve the positional information that receives, and the team leader's who puts down in writing in the note current location is set to the destination of navigational system.
In most cases, the artificial same individual of the founder of fleet and the leader of a group of people in the process of moving of actual fleet, alleged team leader among we embodiment just, certainly, leader of a group of people people and the founder of fleet can not be same people, at this moment, the founder of fleet generates positional information according to the position at the current place of leader of a group of people people.
