Description

Technical Field

[0001] The present application relates to the technical field of vehicle address query, and in particular to a vehicle address query method, device, terminal equipment and storage medium. Background Art

[0002] The vehicle network management system usually needs to display the real-time location of the vehicle and the address information of the location on the map. The address information often needs to be obtained through the API request query from the map provider. Usually, longitude and latitude are saved as floating point numbers, and the address query interface provided by the map service provider also requires the address to be provided in floating point format for query. First of all, the storage characteristics of floating point numbers in computers can only maintain a certain precision and cannot guarantee accuracy, that is, under a certain precision, it can only be rounded. For example, a longitude value of 123.456 may be saved in the computer memory as 123.4599999. In this case, the floating point number in the computer cannot be accurately matched. Secondly, due to the characteristics of satellite positioning, even at the same location point, the positioning results from the positioning module still have slight changes, causing the longitude and latitude data to change accordingly.

[0003] Due to the above characteristics, if you only cache the address by saving the longitude and latitude and its corresponding address, and expect to call the cached address the next time the same longitude and latitude appear, the hit rate will be very low. The low hit rate will cause the address to often not match, and it will be considered a new address, and the address will be queried from the map server again. In the end, different longitude and latitude values ​​of the same address will be called multiple times to query the map server, and the database will also save duplicate data. This inefficient address caching method leads to low system efficiency. Summary of the invention

[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present application.

[0047] When performing address matching on the latitude and longitude information fed back by the vehicle, the match often fails due to the problem of floating-point precision. For this reason, this application reduces the error caused by floating-point precision by setting area coding. The approximate location of the vehicle is directly determined by area coding, and then matched with the data in the memory to determine the address of the vehicle's location, which reduces the calculation load of positioning, reduces the IO operations of the database and disk, and improves the positioning efficiency.

[0048] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0049] The vehicle address query method is described below in conjunction with some specific embodiments.

[0050] Figure 1 A flow chart of a vehicle address query method according to an embodiment of the present application is shown. Exemplarily, the vehicle address query method includes the following steps:

[0051] Step S100, when the geographic location of the vehicle is received, the area code of the area where the vehicle is located is determined according to the geographic location.

[0052] The method of this embodiment is applied to a vehicle network management system, which mainly displays the real-time location of the vehicle and the address information of the location on a map. The vehicle will report its geographical location based on the positioning system, and the geographical location is the latitude and longitude information of the vehicle.

[0053] Address information refers to information about representative addresses such as ground buildings, roads, and landmarks, such as a certain street or a certain community, which is more intuitive than longitude and latitude.

[0054] For the driver, rather than the longitude and latitude, he wants to know the address name of his current location more. The vehicle network management system is used to feedback the corresponding address name according to the longitude and latitude feedback from the vehicle.

[0055] Specifically, when the vehicle longitude and vehicle latitude of the vehicle are received, preset coding calculations are performed respectively, and after the calculations, the area code of the area where the vehicle is located can be obtained.

[0056] The calculation process may be to process the vehicle longitude and the vehicle latitude according to a preset accuracy to obtain an integer value of the vehicle longitude and an integer value of the vehicle latitude;

[0057] The integer value of the vehicle longitude and the integer value of the vehicle latitude are concatenated in a preset manner to obtain a corresponding position code.

[0058] For example, if the preset precision is two decimal places, that is, accurate to 0.01, when processing data, for the data 10.234, 0.004 will be directly rounded off, and the data after processing will be 10.23. Similarly, for 10.235, 0.005 will be rounded off. This is not a rounding rule, but only retaining the data within the precision, and directly rounding off the data outside the precision.

[0059] Then convert the data into an integer. For 10.23, you need to multiply it by 100 to get the integer 1023. It can be understood that if the precision is 3 decimal places, then for the number 10.456, it will be multiplied by 1000 to get 10456.

[0060] The above method can be used to obtain the integer value of the vehicle's longitude and the integer value of the vehicle's latitude respectively.

[0061] For these two integer values, corresponding concatenation operations can be performed to obtain corresponding encoding values.

[0062] The splicing rule may be to store the integer value of the vehicle's longitude in the lower position and the integer value of the vehicle's latitude in the upper position. Similarly, there are multiple splicing methods, and the splicing method can be spliced ​​in an agreed manner. In this way, the area code is obtained, indicating that the vehicle is in the area represented by the area code.

[0063] It can be seen that in this embodiment, by calculating the area code, the area where the vehicle is located and the corresponding area code can be directly determined without matching and comparing, and the area code can point to the longitude and latitude coordinates under a preset accuracy. As long as the preset accuracy is set reasonably, there will not be much deviation. For example, if 0.01 is used as the preset accuracy, 0.01 longitude and latitude is about 1.1 kilometers. This range is not large and is within the controllable error range, so it can also meet the requirements of vehicle monitoring.

[0064] In order to explain the principle here conveniently, the preset accuracy is 0.01 for explanation. The area of ​​this embodiment is demarcated with the preset accuracy as the interval range. Each area is divided according to the longitude and latitude span of 0.01 degrees. For example, 0 degrees east longitude to 0.01 degrees east longitude, 0 degrees north latitude to 0.01 degrees north latitude is an area. All the longitude and latitude coordinates in this area are calculated according to the above calculation method, and the final code value is the same. According to the above method, multiple areas can be divided. It can be known that the longitude and latitude in each area can be calculated according to the above method. The same code value can be calculated, so the code value can represent the area. Therefore, in order to determine the location of the vehicle in this embodiment, the above calculation method can be used to initially determine which area it falls into.

[0065] The area coding method of this embodiment is actually to demarcate multiple areas by reducing the accuracy, so that before matching the coordinates, it is possible to roughly determine in which area the coordinates of the vehicle are located. Then, when matching the coordinates, only the address data in the area needs to be used for matching, which reduces the data pressure faced during matching.

[0066] Step S200: determining whether the address data of the area is in the memory according to the area code.

[0067] The area code can be used to directly find the address data stored in the corresponding area. The address data in the area is stored in correspondence with the area code of the area based on the relative position of the address. Therefore, after determining the area code, it can be used as an index to find all the corresponding address data.

[0068] The relative position here refers to the difference between the longitude and latitude of the address and the longitude and latitude of the area.

[0069] Its calculation expression is:

[0070] Relative longitude = address longitude - area longitude;

[0071] Relative latitude = address latitude - area latitude;

[0072] The regional longitude and regional latitude are longitude and latitude values ​​representing the region, which are calculated based on any sampling point in the region and a preset accuracy.

[0073] Taking the preset precision of 0.01 as an example, the regional longitude is the longitude of the sampling point multiplied by 100, then rounded and divided by 100. The regional latitude is the latitude of the sampling point multiplied by 100, then rounded and divided by 100.

[0074] In the above calculation process, 100 is the reciprocal of the preset precision of 0.01. After multiplying by 100 and rounding, only the integer digits are retained, and all the digits at the decimal point are removed. Then dividing by 100 regresses the digits, and finally the regional longitude and regional latitude representing the area are obtained.

[0075] for example:

[0076] Longitude 123.456789, latitude 23.456789, the longitude and latitude coordinates of the area where it is located are 123.45, 23.45.

[0077] Longitude -123.456789, latitude -23.456789, the base coordinates of the area where it is located are -123.45, -23.45.

[0078] In this way, the regional longitude and latitude can be obtained for calculation. It can be understood that when the preset precision is other values, such as 0.1, or 0.001 and other values, the regional longitude and latitude can also be calculated in the above method, and then combined with the previous formula to calculate the relative longitude and latitude.

[0079] The time calculated from the relative longitude and latitude is a floating point number. In order to reduce storage space, in one embodiment, the relative longitude and latitude can be integerized, which reduces the number of bytes required to be saved. At the same time, after being converted into an integer, it is also convenient for comparison and calculation compared to floating point numbers.

[0080] For example, when the preset precision is 0.01, the calculated relative longitude is 0.00345. In order to save data conveniently, only some valid data can be saved in integer form. For example, if only 34 is saved, the relative longitude can be multiplied by 10000 to get 34.5, and then rounded to 34. Here 10000 is the square of the reciprocal of the precision. At this time, two digits of relative precision can be saved. If three digits are to be saved, it can be multiplied by 100000, and so on. The number of digits to be saved can be calculated by the number of digits to be saved and the reciprocal of the precision, and finally the relative position is saved with a shorter integer.

[0081] After the regional code is determined, the corresponding regional code will be searched in the memory first, because the memory caches the data that has been called, which is faster than reading data from the database.

[0082] If the address data corresponding to the area code is not read from the memory, it is necessary to find the corresponding address data from the database through the area code and load it into the memory for subsequent matching operations.

[0083] In one embodiment, if there is no vehicle in a certain area, the address data corresponding to the area can be cleared from the memory to make room for other data. It is understandable that, except for cities, highways and towns, vehicles rarely pass through most areas, so for some sparsely populated areas, their data may not be put into the cache. When there is no vehicle in the area, the address data in this area can also be cleared to avoid wasting storage space.

[0084] When a vehicle passes through an area for the first time, the address data corresponding to the area code may not be read from the memory. At this time, it is necessary to obtain the address data corresponding to the area code saved in the database and load it into the memory. When the vehicle passes through the area subsequently, the data in the memory can be directly called for matching.

[0085] Step S300: If the address data of the area is in the memory, matching is performed based on the geographical location and the address data. If the same address data is matched, the current address of the vehicle is fed back.

[0086] When the address data corresponding to the area code can be found from the memory, the geographic location and the address data can be matched to find the address where the current vehicle is located.

[0087] The address data is a relative position, so the relative position of the vehicle's geographic location must also be calculated, and then the relative position of the vehicle and the relative position of the address data are compared. When the same relative position is matched, the address of the current vehicle can be found.

[0088] In this embodiment, the calculation method of the relative position is given in the above steps and will not be repeated here.

[0089] After finding the vehicle's address in the above manner, the result can be fed back to the vehicle to complete the query of the vehicle's current address. The current address refers to an address in the form of "such and such road" or "such and such community", which can be an address named by an administrative division, so that the driver can intuitively know his or her location through these address names.

[0090] In addition, if the same address data is not matched, or the address data of the area is in the memory but expired, the address data in the area corresponding to the area code will be updated through the map query interface before the matching operation is performed.

[0091] Among them, if the corresponding address is not matched, it means that there may be errors in this match, and the operator's data is needed for feedback. The expiration of data takes into account that some landmark buildings may change with the passage of time. For example, there is an office building in a certain place, but 50 years later, the office building is demolished and a park is built. If the data is still old data, an incorrect address will be fed back. Therefore, this embodiment can set an effective time. If it exceeds the effective time, it means that the saved address is expired and there is a risk of change, and it needs to be updated. Otherwise, it does not need to be updated.

[0092] The method for determining expiration may be to set a preset expiration time, such as 10 years, 20 years, etc. Different expiration times may be set for different addresses. For example, for residential areas, they will not be demolished easily, so the expiration time may be set to more than 70 years. For some commercial areas such as shops and office buildings, which have higher liquidity, the preset expiration time may be shorter, such as 5 years or 3 years.

[0093] The vehicle address query method of this embodiment adjusts the accuracy of the longitude and latitude of the vehicle location by means of area coding, and then avoids the matching problem caused by floating-point precision by using the relative longitude and latitude and address data for matching, thereby improving the matching efficiency, thereby reducing the scenario of querying the map information provided by the operator, increasing the speed of the entire address feedback, effectively reducing the API calls to the address server supplier, and effectively reducing the cost of map use.

[0094] The step of updating the address data in the area corresponding to the area code is as follows: Figure 2 As shown, including:

[0095] Step S400: Acquire address information that needs to be updated.

[0096] The address information to be updated is all the address information in the current area corresponding to the area code calculated in the previous step, which can be obtained through the interface provided by the operator. Because the longitude and latitude coordinates of the area are known, all the address data within the area can be obtained from the interface provided by the operator based on the coordinates.

[0097] The address information includes the address name and the corresponding address longitude and address latitude.

[0098] There may be multiple addresses in one area, for example, there may be multiple addresses such as a certain community and a certain road, and the address data of all addresses will be obtained to ensure that the latest address information is obtained.

[0099] It should be noted that these addresses may occupy a relatively large area, such as buildings, streets or communities spanning multiple regions, which will also occupy a portion of the area currently required to be updated.

[0100] In the current area, the longitude and latitude corresponding to these occupied areas will also be obtained as address information. If there are 100 points, 100 corresponding longitude and latitude coordinates will be obtained. Similarly, one address can correspond to multiple longitude and latitude coordinates.

[0101] Moreover, for address information that spans multiple regions, the complete address information will be obtained for each address, not just the address information in the region. Because when a new building appears in a certain region, if it spans other regions, it must also be a new building for other regions. Therefore, for the new address, the entire address information will be obtained for body update, that is, the address data in other regions involved in the address will be updated at the same time, rather than just updating the content in the current region, which can also reduce the access to the operator API.

[0102] Step S500: determining the area code of the area according to the address information.

[0103] The acquired address information is also coded and calculated in the same manner as in the above steps to obtain the corresponding area code.

[0104] For addresses that only exist within the area, their address information is also within the area, so a simple match and comparison can be performed for secondary confirmation to ensure that the address information is correct.

[0105] For addresses that span multiple areas, it is necessary to determine the areas where each address data is located. Every time an area is involved, the area involved also needs to update the address information, so as to determine which areas need to be updated this time.

[0106] In this way, by calculating the area code corresponding to the address information, the area corresponding to each address information that needs to be updated can be determined, thereby avoiding errors when updating data.

[0107] Step S600, calculating the relative geographical location of the address information in the area where it is located.

[0108] The relative geographical location is as described in step S200 above, which is the difference between the longitude and latitude of the address and the longitude and latitude of the region. The calculation process will not be repeated here.

[0109] If the address data only exists in the current area, it is only necessary to calculate the relative longitude and latitude of the address data in the area. If the address data exists in multiple areas, it is necessary to calculate the relative longitude and latitude in each area respectively.

[0110] Step S700: The area code, the relative geographical location, the address and the current update time are stored in association with each other.

[0111] Then, the area code, the relative geographical location, the address and the current update time are associated and stored, thus completing the update of the address data in the area. The stored update time is used to determine whether the address data is expired in the aforementioned step S300.

[0112] The address update process of this embodiment determines the area by calculating the area code of each latitude and longitude coordinate of the address, and then reduces the amount of data that needs to be stored by calculating the relative position. When performing geographic matching, it is only necessary to match the relative position to determine the address. At the same time, the relative position reduces the complexity of storing data and is no longer a floating point number, avoiding the precision problem caused by floating point numbers, thereby improving the matching success rate during address query.
