Detailed Description
The technical solution of the present invention will be described in detail with reference to examples.
The principle of the invention is as follows: the server adds mark information and direct storage original positioning data to the original positioning data that positioning device reported, and original positioning data storage back, the server carries out the selectivity conversion to the original positioning data of storage, and when terminal equipment requested to obtain the positioning data, the server carried out the selectivity conversion to the original positioning data in the positioning data that terminal equipment requested, and what final terminal equipment obtained all was the data after the conversion.
Specifically, the positioning data storage, conversion and query method of the present invention is applied to a positioning data storage, conversion and query system, the system includes a positioning device, a server and a terminal device, the server is respectively connected and communicated with the positioning device and the terminal device, and the positioning data storage, conversion and query method includes:
the method comprises the steps that a positioning device collects original positioning data and sends the collected original positioning data to a server;

The method is further optimized, and specifically comprises the following steps:
the method further comprises the steps that when the server returns the obtained converted data corresponding to the selected original positioning data and the read converted positioning data in all the positioning data to the terminal equipment, the server asynchronously replaces the stored corresponding original positioning data with the corresponding converted positioning data, and asynchronously updates whether the data corresponding to the converted positioning data is converted or not to convert the mark. Whether the positioning data and the data conversion mark are updated in an asynchronous mode, the actual waiting time of a user is only the time from the terminal equipment initiating the request to the server returning the converted positioning data, and the time for updating the positioning data and the data conversion mark is not calculated in the waiting time, so that the efficiency of positioning data query is further improved.
And if the original positioning data exists in all the read positioning data, the server selects the latest preset number of original positioning data from all the existing original positioning data according to the positioning time sequence of all the existing original positioning data. Generally, the user needs to compare the new positioning data, so that the user needs to convert the new positioning data preferentially during conversion.
The preset rule may include: and the server reads the latest preset number of original positioning data according to the positioning time sequence of the original positioning data. Generally, the user needs to compare the new positioning data, so that the user needs to convert the new positioning data preferentially during conversion.
The preset rule may include: and when the resource utilization rate of the server is lower than a preset resource utilization rate threshold value, the server reads a preset amount of original positioning data. When the server resources occupy less, the original positioning data is converted, so that the server resources can be fully utilized, and the performance of the server cannot be influenced.
The preset rule may include: the server reads a preset amount of original positioning data at regular time. The mode of reading the original positioning data at regular time for conversion ensures that a part of the original positioning data uploaded by the positioning equipment in a period of time can be converted, and the processing pressure of the server during positioning data query is reduced.
The original positioning data comprise satellite original positioning data and WIFI original positioning data, when the server reads original positioning data with the same data types in preset quantity according to preset rules, the preset quantity of the read WIFI original positioning data is smaller than the preset quantity of the read satellite original positioning data, and when the server selects the original positioning data with the preset quantity from all the original positioning data, the preset quantity of the selected WIFI original positioning data is smaller than the preset quantity of the selected satellite original positioning data. Because the conversion efficiency of the satellite original positioning data is higher than that of the WIFI original positioning data, when the server performs timing conversion, in order to ensure that the conversion time of single WIFI original positioning data is approximately the same as that of the satellite original positioning data, the number of the WIFI original positioning data needing to be converted, which is read or selected at one time, is smaller than that of the satellite original positioning data needing to be converted, which is correspondingly read or selected.
Examples
The following specifically exemplifies the technical solution of the present invention.
The positioning data storage, conversion and query method is based on the existing positioning data storage, conversion and query system, the system comprises positioning equipment, a server and terminal equipment, and the server is respectively connected and communicated with the positioning equipment and the terminal equipment. The following description takes raw positioning data as GPS raw positioning data and WIFI raw positioning data as an example.
Specifically, the present example stores, converts, and queries GPS positioning data and WIFI positioning data through the following steps.
Step S1, the positioning equipment collects GPS original positioning data and WIFI original positioning data and sends the collected GPS original positioning data and WIFI original positioning data to the server.
Step S2, the server adds corresponding mark information for each piece of received GPS original positioning data and WIFI original positioning data, and stores the received GPS original positioning data and the mark information thereof, the WIFI original positioning data and the mark information thereof, wherein the mark information comprises a data type and a data conversion mark, and the data conversion mark is not converted initially.
Step S3, the server periodically reads a preset amount of GPS raw positioning data and/or a preset amount of WIFI raw positioning data, wherein the preset amount of the read WIFI raw positioning data is smaller than the preset amount of the read GPS raw positioning data, the read GPS raw positioning data is the latest preset amount of GPS raw positioning data according to a positioning time sequence of the GPS raw positioning data, and the read WIFI raw positioning data is the latest preset amount of WIFI raw positioning data according to a positioning time sequence of the WIFI raw positioning data.
Step S4, the server invokes an API with a GPS raw positioning data conversion policy to convert the GPS raw positioning data read in step S3 according to the data type of the raw positioning data read in step S3, replaces the stored corresponding GPS raw positioning data with the corresponding GPS positioning data after this conversion, and updates whether the data conversion flag corresponding to the GPS positioning data after this conversion is converted; and/or calling an API with a WIFI raw positioning data conversion strategy to convert the WIFI raw positioning data read in the step S3, replacing the stored corresponding WIFI raw positioning data with the corresponding WIFI positioning data after the conversion, and updating a data conversion mark corresponding to the WIFI positioning data after the conversion into converted data.
Step S5, the terminal device requests the server to acquire GPS positioning data and WIFI positioning data.
Step S6, the server reads all GPS positioning data requested by the terminal device and all WIFI positioning data requested by the terminal device, and for all positioning data of any type read this time, taking GPS positioning data as an example, performs the following processing: the server judges whether each piece of GPS positioning data read this time is original GPS positioning data or converted GPS positioning data respectively through a data conversion mark corresponding to the GPS positioning data, if all the GPS positioning data read are converted GPS positioning data, the server returns all the GPS positioning data read to the terminal equipment, if all the GPS positioning data read have the original GPS positioning data, the server selects a preset number of original GPS positioning data from all the original GPS positioning data, wherein the selected original GPS positioning data is the latest preset number of original GPS positioning data according to the positioning time sequence of the original GPS positioning data, then the server calls an API with a GPS original positioning data conversion strategy to convert the selected original GPS positioning data to obtain converted GPS positioning data corresponding to the selected original GPS positioning data, and returning the obtained converted GPS positioning data corresponding to the selected GPS original positioning data and the converted GPS positioning data in all the read GPS positioning data to the terminal equipment. The processing of all the read WIFI positioning data is the same as the processing principle of the GPS positioning data, and is not repeated here, but the difference lies in that when the server selects the WIFI raw positioning data with the preset number from all the existing WIFI raw positioning data, the preset number of the selected WIFI raw positioning data is smaller than the preset number of the selected GPS raw positioning data.
Step S7, the server asynchronously replaces the stored corresponding GPS original positioning data with the corresponding GPS positioning data after the conversion, asynchronously updates whether the data conversion mark corresponding to the GPS positioning data after the conversion is converted, asynchronously replaces the stored corresponding WIFI original positioning data with the corresponding WIFI positioning data after the conversion, and asynchronously updates whether the data conversion mark corresponding to the WIFI positioning data after the conversion is converted.
In addition, when the server reads the GPS raw positioning data and/or the WIFI raw positioning data in step S3, optionally, the server may further control the reading frequency according to the resource utilization rate of the server, that is, when the resource utilization rate of the server is lower than a preset resource utilization rate threshold, the server reads a preset number of GPS raw positioning data and/or a preset number of WIFI raw positioning data. When the GPS original positioning data and/or the WIFI original positioning data are converted in each step, if the corresponding API supports batch conversion, a batch conversion mode is preferentially adopted.
