Embodiment
Fig. 1 is the structural drawing of system, and as shown in the figure, total system is by terminal 11, and data processing centre (DPC) 12 and display system 13 are formed.Wherein terminal 11 is connected with data processing centre (DPC) 12 by wireless network, carries out the transmission of data, and display system 13 directly is connected with data processing centre (DPC) 12, reads required data presented from data processing centre (DPC) 12.
Data processing centre (DPC) 12 is responsible for the control of disposal system to terminal 11, to the inquiry of data, and storage, functions such as retrieval are the cores of total system.The position data of its receiving terminal 11 passbacks and the inquiry of 13 pairs of data of display system, simultaneously to terminal 11 sending controling instructions, electronic chart, road surface situation etc. also provide data presented to display system 13, simultaneously as the positional information of vehicle.
Fig. 2 is data processing centre's 12 work synoptic diagram.Data processing centre (DPC) 12 is by control section 22, Data Receiving part 21, and the Data Receiving part 23 and the terminal table of comparisons 24 constitute.Control section 22 is connected with Data Receiving part 21 with the terminal table of comparisons 24, and Data Receiving part 21 is connected with Data Receiving part 23 with the terminal table of comparisons 24, and wherein the terminal table of comparisons 24 all plays the function that routing inquiry is provided.Data Receiving part 23 also is connected with display system 13, and information of vehicles is provided.
Control section 22 is responsible for the steering order of transmitting systems, receive the Data Receiving position that the terminal table of comparisons 24 returns after, send the signaling that passes to terminal 11 to Data Receiving part 21.
The terminal table of comparisons 24, its main contents are the termination number of each terminal, and with termination number corresponding Data Receiving address and address data memory, like this three has been constituted a question blank, can by termination number to data locate fast, inquire about, operation such as storage.
Data Receiving part 21 is responsible for the data that receiving terminal 11 is passed back, and is responsible for system directive is sent to terminal 11.
Data Receiving part 23 has been set up a file for each terminal 11, sets up the level Four catalogue according to unique termination number, and each grade got two of termination number.For example termination number is 2050807822 vehicle, and its bibliographic structure is :/20/50/80/78/22.dat.Its benefit is that each termination number has corresponding file unique with it, and this document has comprised relative all information, and by termination number, system can directly obtain the data storage location of this terminal fast.After Data Receiving part 21 received the passback data of terminal 11, by the terminal table of comparisons 24, data storage was carried out in inquiry and the corresponding address data memory of termination number that returns data.Simultaneously, Data Receiving part 23 is gone back the inquiry of 13 pairs of data of receiving and displaying system, provides the data of being inquired about to display system 13.
The method of system works is described with example below.As shown in Figure 3, be information of vehicles datamation process flow diagram, at first be that terminal 11 on the vehicle sends current position information to Data Receiving part 21 (step S31) by wireless network, Data Receiving part 21 receives data, and the termination number (step S32) of acquisition passback data, inquire about the memory address (step S33) of these termination number correspondences then to the terminal table of comparisons 24, if this termination number is arranged in the terminal table of comparisons 24, then data (step S35) are stored in the address that provides according to the terminal table of comparisons 24, if this termination number not in the terminal table of comparisons 24, then Data Receiving part 23 is set up the level Four storage file corresponding with this terminal 11 earlier, stores (step S34) again.
As shown in Figure 4, for system to terminal 11 sending controling instruction process flow diagrams, suppose that system wishes that the stolen vehicle pressure is flame-out, then at first be that control section 22 produces steering order, command terminal 11 control vehicles are flame-out, and need receiver address (the step S41 of control terminals 11 to the terminal table of comparisons 24 inquiry, S42), if in the terminal table of comparisons 24, do not find this termination number, then return message does not have this termination number (step S43), if find the receiver address corresponding with this terminal 11, then steering order is sent to this address, and further be forwarded to controlled terminal 11, vehicle (the step S44 that stops working by this address, S45).
As shown in Figure 5, show memorying data flow journey figure for system.Supposing the system wishes to show the electronic chart of certain its region of vehicle, then at first store data addresses (step S51, S52) according to the termination number of this car to 24 inquiries of the terminal table of comparisons by display system 13, as fail to inquire this termination number, then return message does not have this terminal 11 information (step S54), as inquire this termination number, then, then shown the electronic chart of this vehicle region in display system 13 by the positional information of storage system to display system 13 these terminals 11 of transmission.
The above; only be a kind of embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
