Embodiment
As shown in Figure 1, in the structured flowchart of the distributed computing system based on the GPS operation system of the present invention, the car-mounted terminal 6 that comprises server and wireless connections with it, server comprises processor 1 and the customer data base 2, pending database 3, Distributed Calculation unit 4 and the wireless communication module 5 that are attached thereto.Processor 1 is for resource management and allocation and the process scheduling of server, for example in customer data base 2, inquire about idle vehicle-mounted user side 6, the task bag that Distributed Calculation unit 4 is produced and the idle car-mounted terminal 6 in customer data base establish the link, or have given the car-mounted terminal distribution integral of Processing tasks.Customer data base 2 is for recording the state of validated user and car-mounted terminal 6 thereof, and the integration of finishing the work number and obtaining that records this car-mounted terminal 6.Distributed Calculation unit 4 is compressed into division of tasks in order to the algorithm according to certain the task bag of same format, and generate an obtainable integrated value of car-mounted terminal 6 that completes this task bag according to the calculated amount of task bag, also the result of calculation of car-mounted terminal 6 is spliced into to final calculation result.Server sends to car-mounted terminal 6 by wireless communication module 5 by the task bag, and receives the result of calculation that car-mounted terminal 6 returns.Car-mounted terminal 6 has the utility cession unit, and this utility cession unit receives the processor processing of the task bag received being delivered to car-mounted terminal, and result is uploaded automatically.
The present invention is based on the workflow of the distributed computing system of GPS operation system in conjunction with Fig. 2 explanation.This method comprises the following steps: Distributed Calculation unit 4 is the taking-up task from pending database 3, according to certain algorithm, this division of tasks is become to several subtasks and is compressed into the task bag, can obtain integrated value according to a car-mounted terminal 6 that completes this task of calculated amount generation of this task bag simultaneously; Processor 1 is inquired about validated user in customer data base 2, and vehicle-mounted 6 terminals of the free time of inquiring about this validated user, produce available car-mounted terminal list, and the task bag of compression is cut apart in Distributed Calculation unit 4 and the idle car-mounted terminal 6 of the validated user in customer data base 2 establishes the link, the car-mounted terminal 6 connected with the task bag is labeled as to busy state simultaneously; According to the task bag of having set up and 6 links of idle car-mounted terminal, the task bag sends to car-mounted terminal 6 by wireless communication module 5, and car-mounted terminal 6 returns to a notification message after successfully receiving the task bag, otherwise this task bag will send to other standby terminals, processes; The car-mounted terminal decompress(ion) contracts and processes the task bag received, the utility cession unit is delivered to the car-mounted terminal processor by it and is calculated, and result is uploaded to server automatically, if surpass not upload process result of certain hour, this task bag is resend to other car-mounted terminals and processed; The result that Distributed Calculation unit 4 receives, generate final process result, and processor 1 adds the integration that this car-mounted terminal obtains in customer data base 2.
Describe the workflow of car-mounted terminal 6 in detail in conjunction with Fig. 3.After connecting with server, the utility cession unit receives a packet from server, and decompress(ion) contracts and delivers to the car-mounted terminal processor and processed, and the result after processing is uploaded to server, and starts next task, again receives packet.
For example, GPS service company disposes the Distributed Calculation unit at server end, in client configuration utility cession unit.When server receives task, at first place it in the task queue of pending database, and deliver in order the Distributed Calculation unit and carry out Task-decomposing and be compressed into the task bag, decompose and carry out according to certain algorithm, and calculate accordingly an integrated value.Simultaneous processor is inquired about the idle car-mounted terminal of validated user in customer data base, and set up an available car-mounted terminal list, the number of available car-mounted terminal is not less than the quantity of task bag, preferably have much larger than the quantity of task bag, in order to re-issue the task bag when going out the current task packet loss.Task bag and available car-mounted terminal are set up the linking relationship of a correspondence, and are issued on corresponding car-mounted terminal by mobile communication module, and processor is labeled as busy state by the car-mounted terminal that receives the task bag.The utility cession unit of car-mounted terminal by the task bag decompress(ion) that receives, put into the processor that calculates queue and call car-mounted terminal and processed, last result of calculation uploads onto the server.The result of calculation that each car-mounted terminal of Distributed Calculation unit spliced transmits, generate final calculation result.After receiving the result of calculation of car-mounted terminal, in customer data base, to it, increase corresponding integrated value.
In another embodiment of the present invention, the state of car-mounted terminal is by the utility cession unit record, and when car-mounted terminal is idle, the utility cession unit sends and can receive briefing to server, request allocating task bag.A few minutes of the acquisition of car-mounted terminal can be in order to take out service fee, and for example 100 integrations can be bought navigation Service one time.The task bag received of car-mounted terminal is relevant to its current position.
Certainly; the present invention also has numerous embodiments; in the situation that do not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes or variation; in every case any modification of doing, be equal to replacement, improvement, within protection scope of the present invention all should be included within the present invention's spirit and principle.
