Abstract

The invention belongs to the technical field of intelligent water affair and Internet of Things application, and discloses a method, system and device for obtaining river commander billboard associated information based on mobile terminal positioning and a medium. Uniform two-dimensional codes with identical contents are printed on all the river leader billboards; and the two-dimensional code points to a unified information query entry of the server. And after a user scans the two-dimensional code by using a mobile terminal, the mobile terminal sends real-time positioning coordinates to the server together. And the server automatically matches and returns associated information of the river leader billboard closest to the user through spatial calculation according to the positioning coordinates. And all the billboards use the same two-dimensional code, so that when a background system needs to be upgraded or the URL is changed, any entity billboard does not need to be replaced, and the billboards only need to be updated once at the server side. The problem of scanning disorder in a complex environment is avoided, and it is ensured that information acquired by the public strictly corresponds to the position where the public is located. A user does not need to distinguish which card is scanned, and the most relevant information can be obtained through code scanning.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart water and Internet of Things, and particularly relates to a method, system and device for obtaining associated information of a river length public notice board based on mobile terminal positioning and a medium. BACKGROUND

[0002] The full implementation of the river length system is an important measure to implement the green development concept and promote the construction of ecological civilization. The river length public notice board is an important carrier for publicly disclosing river length information, responsibilities, management targets and supervision methods to the society. At present, most of the river length public notice boards have printed two-dimensional codes, and the public can quickly obtain relevant information by scanning the two-dimensional code with a mobile phone.

[0003] However, the existing technical solutions have obvious defects:

[0004] One code for one board, difficult to maintain: each public notice board has its own two-dimensional code with different content. When the background service or system architecture needs to be updated, the two-dimensional code on each public notice board needs to be re-made and replaced, which is costly and cumbersome.

[0005] Confusion and error: in densely populated river areas, the public may scan the two-dimensional codes of multiple public notice boards at the same time, or scan the two-dimensional codes of non-target public notice boards due to long distance, resulting in the obtained information not matching the current river.

[0006] Poor flexibility: static and exclusive two-dimensional codes cannot provide dynamic and most relevant information and services according to the actual position of the user.

[0007] Therefore, there is an urgent need in the field for a river length public notice board information obtaining method that can overcome the above-mentioned defects and achieve unity, precision and easy maintenance. SUMMARY

[0008] The purpose of the present application is to provide a method, system and device for obtaining associated information of a river length public notice board based on mobile terminal positioning, in order to solve the problems of difficult maintenance, information confusion and poor flexibility caused by "one code for one board" in the prior art.

[0009] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a method for obtaining associated information of a river length public notice board based on mobile terminal positioning, the core idea of which is to print a unified two-dimensional code with the same content on all river length public notice boards. The two-dimensional code points to a unified information query entrance of the server. When a user scans the two-dimensional code with a mobile terminal (such as a mobile phone), the mobile terminal will send its real-time positioning coordinates to the server. The server automatically matches and returns the associated information of the river length public notice board closest to the user according to the positioning coordinates through spatial calculation.

[0010] The method specifically includes the following steps:

[0011] The mobile terminal scans a unified two-dimensional code to access the encoded URL address;

[0012] The mobile terminal sends a request to the server, and the request carries the real-time positioning coordinates of the mobile terminal;

[0013] The server receives the request and uses the positioning coordinates to find the nearest target river length public bulletin in the database;

[0014] The server returns the associated information of the target river length public bulletin to the mobile terminal for display.

[0015] The beneficial effects of the present application are as follows:

[0016] Greatly reduce maintenance costs: all public bulletins use the same two-dimensional code. When the background system needs to be upgraded or the URL is changed, there is no need to replace any physical public bulletin, and only one update on the server is required, achieving "one change for all changes".

[0017] Information acquisition is accurate and reliable: through positioning technology, the nearest public bulletin is automatically matched, effectively avoiding the problem of scanning disorder in complex environments, and ensuring that the information obtained by the public strictly corresponds to the location.

[0018] Improve user experience and interactivity: users do not need to distinguish which block to scan, and can obtain the most relevant information by scanning the code. At the same time, the system can provide more personalized services based on accurate positioning, such as "one-key reporting of current location problems". BRIEF DESCRIPTION OF DRAWINGS

[0021] Figure 3 is the detailed flowchart of the server matching and verifying the target river length public bulletin in the embodiment of the present application. DETAILED DESCRIPTION

[0022] Reference Figure 1 and Figure 2 The system of the embodiment includes a mobile terminal, a server (cloud server), and a river length public bulletin database.

[0023] First, build a river length public bulletin database. Record the unique ID, accurate latitude and longitude coordinates, and associated detailed information of each river length public bulletin in the jurisdiction, such as river name, river length name and position, management target, water quality report link, news updates, etc.

[0024] Then, a unified two-dimensional code is generated, and this two-dimensional code is printed on all river length signs.

[0025] When the public (user) is beside river A, scans the unified two-dimensional code on the sign using a mobile phone, the process is as follows:

[0026] The mobile phone scans the two-dimensional code and parses the URL address.

[0027] The browser or specific application of the mobile phone accesses the URL address and automatically calls the GPS / Wi-Fi / base station positioning function of the mobile phone to obtain the current latitude and longitude coordinates (for example: lat: 39.9042, lng: 116.4074), and sends the coordinates to the server through the HTTP request parameter (such as?lat=39.9042&lng=116.4074).

[0028] The server receives the request and extracts the positioning coordinates.

[0029] Referring to Figure 3 , the server queries all sign locations in the database and calculates the distance between the received coordinates and each sign coordinates. Through comparison, it is found that the nearest sign is "A river 001 sign" and the distance is 15 meters, which is less than the preset threshold of 100 meters.

[0030] The server retrieves all associated information of "A river 001 sign" from the database and generates an H5 page.

[0031] The server returns the H5 page as a response to the user's mobile phone.

[0032] The user's mobile phone browser displays the page, and the user can see the accurate information corresponding to river A.
