It should be noted that the application programming interfaces 204 are not that simply signaling and/or data are transmitted,
But including the definition to data structure（Including the definition to various parameters）, the identification to signaling and/or data, bang path
And the definition of control method（In the way of function）, in specific embodiment, the application programming interfaces 204 can be defined as base
In the dynamic link library of WinCE operating system platforms（DLL, Dynamic Link Library）, by the man-machine interface 201,
Remote service unit 202, navigation elements 203 are called and run to it.
The application programming interfaces 204 also include readjustment unit（Not shown in figure）, for by the confirmation knot of the signaling
Fruit is passed back to the man-machine interface 201, the remote service unit 202 or the navigation elements 203.The confirmation result can be with
For the success or failure and the feedback information of failure cause generated in the service request implementation process of user.For example, when user is logical
Cross after the service request that man-machine interface 201 proposes " obtaining current navigation position information ", in the implementation process of the service request,
Signaling is by calling man-machine interface application programming interfaces 204a, remote service unit application programming interfaces 204c or navigation elements should
Transmission is realized with routine interface 204b function or is controlled, and will confirm that result is called by the readjustment unit on invocation
The feedback information of success or failure and failure cause accordingly returns to the man-machine interface 201, the remote service unit 202 afterwards
Or the navigation elements 203, also, confirm that result can also generate prompt message request user and further be grasped according to described
Make, if proposing the service request of " obtain current navigation position information " but acquisition have failed, need delivery confirmation result to carry
Show user " obtaining current navigation position information " failure, it is possible to which inquiry is retried or cancelled.
The man-machine interface 201 includes state control display unit, for single to the remote service unit 202 and navigation
The execution state of each business is controlled and shown in the running status and service request implementation process of member 203.The long-range clothes
The running status of business unit 202 and navigation elements 203 includes：Whether the remote service unit 202 and navigation elements 203 are in
Starting state, the mode of operation of the remote service unit 202 are in explicit mode or implicit mode etc..
Fig. 5 shows the timing diagram of the powering method of the guider of the present embodiment, with reference to Fig. 4 and Fig. 5 to this reality
The powering method for applying example is described in detail.
Start man-machine interface 201 first, the Starting mode of the man-machine interface 201 is foreground initiation, i.e., in start-up course
In, the user interface in the man-machine interface 201 is used as desktop.
After the man-machine interface 201 startup, start the remote service unit 202, the remote service unit 202
Starting mode starts for backstage, i.e., in the start-up course of remote service unit 202, desktop remains as the man-machine interface
201 user interface.
After the remote service unit 202 startup, the remote service unit application programming interfaces 204c is carried out just
Beginningization.Due between the man-machine interface 201 in the guider of the present embodiment, remote service unit 202 and navigation elements 203

During, start the remote service unit application programming interfaces 204c in application programming interfaces 204 first, beneficial to each module of guarantee
Between proper communication.
After pre-set delay after the remote service unit 202 startup, to the man-machine interface application programming interfaces
204a is initialized, and the pre-set delay is primarily to ensure that the remote service unit application programming interfaces 204c can
Start prior to man-machine interface application programming interfaces 204a, the preset time can be 1 second to 3 seconds, be preferably 2 in the present embodiment
Second.
After remote service unit application programming interfaces 204c initialization, the first ready signal TSP_OK is produced.
201 pairs of the man-machine interface remote service unit application programming interfaces 204c is adjusted back（call back）, adjust back process
It can be completed by the readjustment unit in the application programming interfaces, to realize the confirmation to the first ready signal TSP_OK.
In one specific embodiment, the readjustment process can be realized by call back function.Confirming the first ready signal TSP_
After OK, that is, after confirming that the remote service unit application programming interfaces 204c is initialized and finishing, start the navigation
Unit 203, the Starting mode of the navigation elements 203 also starts for backstage.The navigation elements 203 are in remote service unit
Start to start again after 202 startups, so as to avoid two modules while system is busy caused by starting, resource is overspend, screen lock
Wait indefinitely problem.
After the navigation elements 203 are started, the navigation elements application programming interfaces 204b is initialized.Institute
State after the completion of navigation elements application programming interfaces 204b initialization, sent to the remote service unit application programming interfaces 204c
Second ready signal Navi_Notify, the remote service unit application programming interfaces 204c is to second ready signal
Navi_Notify carries out transfer.Afterwards, 201 pairs of the man-machine interface remote service unit application programming interfaces 204c is again
It is secondary to be adjusted back, after the second ready signal Navi_OK confirmations of transfer, namely confirm the navigation elements application programming interfaces
After 204b is initialized, the man-machine interface 201 activates the remote service unit 202 and navigation elements 203.The activation
It can be completed by the state control display unit in the man-machine interface 201, will the remote service unit 202 and navigation
Unit 203 is designated starting state, and user can be sent by the user interface of the man-machine interface 201 and be directed to remote service
The service request of unit 202 and navigation elements 203, such as " dialing navigation Service phone ", " starting navigation ".Before activation,
The remote service unit 202 and navigation elements 203 are identified as inactive state, so as to shield service of the user to them
Request, it is to avoid the problems such as equipment, program malfunction caused by the maloperation of user.
To sum up, the powering method for the guider that the present invention is provided successively starts man-machine interface, remote service unit successively
And navigation elements, it is to avoid system is busy caused by mutual preempting resources multiple modules start simultaneously when, electrifying startup process mistake
Long the problems such as.
Further, the technical program after man-machine interface, remote service unit, navigation elements all start on man-machine boundary
The remote service unit, navigation elements are activated in face, it is shielded before activation, so as to avoid in remote service
The problems such as user malfunctions to equipment caused by their maloperation before unit, navigation elements start.
In addition, each module realizes mutual synchronization by corresponding ready signal after starting in the technical program, it is ensured that
Each module can quickly and orderly startup, improve electrifying startup speed.
