GPS positioning device closes positioning function and communication function, and Detection task table in real time.

Description

A kind of method for reducing GPS device power consumption

Technical field

The present invention relates to a kind of method for reducing GPS device power consumption.

Background technology

Currently, the positioning of bus is realized by the GPS device installed on bus, due to GPS device Not bus is from carrying device, thus it is main during its use be also to rely on its cells and be powered, and a GPS is set The standby cruising time in the case of lasting unlatching is usually no more than 3 hours, if persistently carrying out vehicle-mounted charge, to GPS device Very bad influence is necessarily caused again from charged pool, causes GPS device battery fragile, so as to cause public transport company for public transport The cost of car GPS location remains high.

The content of the invention

In order to solve the above technical problems, the invention provides a kind of method for reducing GPS device power consumption, reduction GPS is set The electricity of GPS device has been effectively ensured by opening and closing GPS device positioning function and communication function in good time in the method for standby power consumption Pond endurance, also improves the service life of GPS device battery.

The present invention is achieved by the following technical programs.

A kind of method for reduction GPS device power consumption that the present invention is provided, comprises the following steps：

1. the GPS positioning device on bus obtains task from task list, and opens positioning when reaching the execution time GPS position information is inputted to send to the public bus network on server to project by function and communication function as customer location to be calculated Device module；

2. public bus network projection calculator module reads public bus network point data base, customer position information table to current simultaneously Affiliated circuit is judged；

3. public bus network projection calculator module according to belonging to circuit line speed table and the virtual bus number of history According to being predicted to the arrival time stood under the bus；

4. public bus network projection calculator module is updated according to predicting the outcome to the virtual public transport car data of history, And start time progress task arrangement to GPS positioning device according to predicting the outcome, and task arrangement is fed back into task list progress Update；

5. GPS positioning device closes positioning function and communication function, and Detection task table in real time.

The step 4. in, the virtual public transport car data of history is updated and fictionalized for the GPS location according to user One bus, if there is bus near the GPS location of user, updates the position of bus；If the GPS positions of user No bus nearby is put, then newly-built one virtual bus.

The rolling average speed of the step 3. each website of the middle circuit speedometer record affiliated circuit of bus, the shifting Dynamic average speed is to reach next website average speed from our station, and the lower CFS to CFS time is predicted with the rolling average speed.

The beneficial effects of the present invention are：By opening and closing GPS device positioning function and communication function in good time, effectively The battery durable ability of GPS device is ensure that, the service life of GPS device battery is also improved, so as to greatly reduce public affairs Hand over to the collective or the state department for bus GPS position maintenance cost, while lower fault rate also greatly improves the seating body of passenger Test and the influence to public transport company.

Brief description of the drawings

Fig. 1 is the principle schematic of the present invention；

Fig. 2 is Fig. 1 schematic flow sheet.

Embodiment

Be described further below technical scheme, but claimed scope be not limited to it is described.

The characteristics of public bus network is, what its travel route was to determine；And the purpose of bus positioning is to let the user know that Which station bus have passed through, and will reach which station；And the particular location during being travelled to bus is not to be concerned about very much； Therefore, the key of bus positioning, which is to ensure that bus running has been arrived, can submit the GPS position information of oneself when near website Position of bus is calibrated, and the middle position of bus for running over journey is estimated by server, specifically For, a kind of method of reduction GPS device power consumption as shown in Figure 1 and Figure 2 comprises the following steps：

1. the GPS positioning device on bus obtains task from task list, and opens positioning when reaching the execution time Function and communication function are sent GPS position information as customer location input to the public bus network projection calculator on server Module；

2. public bus network projection calculator module reads bus routes point data base, customer position information table to current simultaneously Affiliated circuit is judged；

Each several part functions of modules mentioned above is mainly as follows：

Public bus network projection calculator：According to the virtual bus number of customer location and public bus network data, and history According to the positional information with user oneself last time, COMPREHENSIVE CALCULATING simultaneously updates virtual public transport car data and customer position information.According to public affairs Hand over line information, it is predicted that up to the lower station time.Increase new task：GPS location and the submission of user is obtained in the lower station time；

Customer position information table：Remember user position and time, and have recorded the related virtual public transport of the user Car；

Line speed table：Record the rolling average speed of each website of the affiliated route of bus, the rolling average speed To reach next website average speed from our station, the lower CFS to CFS time is predicted with this rolling average speed.

Public bus network point data base：The running route of public bus network, can be to the GPS location of user by these data Information is corrected；

Virtual bus database：One bus is fictionalized according to the GPS location of user, if deposited near GPS location In bus, then the position of bus is updated；If there is no bus near GPS location, a newly-built virtual vehicle.

Task list：Task list is stored in as task because the arrival time at every station differs, therefore by acquisition GPS location, by Task list extracts to dispatch GPS.

Thus, eliminate unnecessary GPS location to submit so that client GPS power consumptions are greatly reduced.
