[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The identification system for underground pipeline information has a structure such as Figure 1 As shown, it includes a signboard and a mobile terminal. The signboard is set on the ground to mark the underground pipelines. The mobile terminal is used to write information to the signboard. The mobile terminal writes information to the signboard through NFC transmission.

[0019] The signboard includes a stainless steel cover 1 and an NFC chip 2. The stainless steel cover 1 is buckled on the ground, a circular through hole is opened in the center of the top surface of the stainless steel cover 1, and the NFC chip 2 is arranged inside the stainless steel cover 1 below the through hole to embed underground pipeline information.

[0020] Circular ABS films are glued on both sides of the NFC chip 2. The diameter of the ABS films is slightly smaller than the diameter of the inner end surface of the stainless steel cover 1. The NFC chip 2 is located in the center of the two ABS films. A circle of 3M adhesive is attached to the edge of the upper ABS film to attach the ABS film to the stainless steel cover 1 and place the ABS film in the cover to move.

[0021] When attaching the ABS film to the stainless steel cover 1, tear off the protective film on the 3M adhesive backing, and fix the ABS film on the inner end surface of the stainless steel cover so that the NFC chip corresponds to the through hole. When replacing the NFC chip, just tear off the original ABS film from the stainless steel cover, stick the new ABS film with the NFC chip back into the stainless steel cover, and use the mobile terminal to write information to the NFC chip.

[0022] The mobile terminal includes a housing 3, a liquid crystal display screen 4, a USB interface 5, a control mechanism and a Beidou positioning module. The liquid crystal display screen 4 is arranged on the housing 3 to display pipeline information, the USB interface 5 is arranged at the bottom of the housing 3 to connect to the host computer to obtain underground pipeline database information, the control mechanism is arranged inside the object 3 to write the underground pipeline database information into the NFC chip 2, and the Beidou positioning module is used to locate the position of the sign. The output ends of the USB interface 5 and the Beidou positioning module are respectively connected to the input ends of the control mechanism, the output end of the control mechanism is connected to the input end of the liquid crystal display screen 4, and the control mechanism transmits information with the NFC chip 2 through the NFC short-range wireless signal.

[0023] The liquid crystal display screen 4 is a touchable liquid crystal display screen, which can not only display underground pipeline information, but also input information through the liquid crystal display screen.

[0024] The structural diagram of the control mechanism is as follows Figure 2 As shown, it includes an information identification unit, a microcontroller and an NFC transmission module. The information identification unit is used to identify database information, the microcontroller is used to control information transmission, and the NFC transmission module is used to write information to the NFC chip 2. The output end of the USB interface is connected to the input end of the information identification unit, the output end of the information identification unit is connected to the input end of the microcontroller, the output end of the microcontroller is connected to the input end of the NFC transmission module, and the output end of the NFC transmission module writes information to the NFC chip through the NFC function.

[0025] The information identification unit includes a user management module, a map management module, a query management module and a database module. The user management module is used to verify user information, the map management module is used to browse the map, the query management module is used to query pipelines and pipeline points, and the database module is used to store pipeline data and basic data. The output ends of the user management module, the map management module, the query management module and the database module are respectively connected to the input ends of the microprocessor.

[0026] The user management module is used to verify user information and prevent unidentified users from using the system. When a user logs into the system, the user enters the user name and password on the LCD screen. The user management module verifies whether the user name and password match. Only after the verification is passed can the user log into the system. Since the mobile terminal does not have an Internet chip, it will not connect to the network, ensuring the security of the data.

[0027] The map management module enables users to browse maps and locate space, and is divided into the following three functions: data browsing function, layer management function and measurement function.

[0028] The data browsing function is used to browse three types of maps: electronic maps, topographic maps, and planning maps. It organizes the basic data into sliced ​​map services and provides them to users on mobile terminals. The three map services include electronic maps, topographic maps, and planning maps. Users can switch between them according to their needs through the LCD screen.

[0029] The layer management function is used to browse the map. It organizes data according to pipeline standard classification. Users can turn on or off the display of layers as needed through the LCD screen.

[0030] The measurement function is used to measure the length and area of ​​underground pipelines to ensure the accuracy of the information entered into the NFC chip.

[0031] The query management module can realize the query of underground pipelines and pipe points. Users can use point-selection operations to query the type and material of pipelines and pipe points, and can also view the legends of pipelines and pipe points to understand the basic information of underground pipelines.

[0032] The database module realizes the storage of underground pipeline data and basic data. It is developed using the database SQLite, and realizes the storage of the system's pipeline data and basic data, including the storage and update of topographic maps, electronic maps, planning maps, various pipelines, user information and other data. The database is stored on the mobile terminal, and the mobile terminal removes the networking chip, which can solve the management problem of not allowing confidential information to be accessed online and not allowing confidential information to be accessed online.

[0033] The present invention is connected to the host computer through the USB interface, and the data information in the host computer is copied into the mobile terminal through the USB interface and displayed on the map on the LCD screen. The operator holds the mobile terminal to view the sign information of each mark point in the map, and directly writes it into the NFC chip in the sign through the NFC function. In addition, the mobile terminal is provided with a Beidou positioning module, which can automatically determine the position of the mark point, and automatically display the information of the underground pipeline at that place on the LCD screen.

[0034] When construction workers are working, they open a handheld terminal with NFC function. When the handheld terminal is close to the NFC chip, the information and burial status of the underground pipeline at the marked point can be displayed on the handheld terminal, which is convenient for construction workers.
