Detailed Description

In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In order to improve the accuracy of outdoor positioning, as shown in fig. 1, an embodiment of the present disclosure provides an outdoor positioning system, including:

step 101, a base station and a mobile station which is connected with the base station through a LORA network communication.

A base station, i.e. a public mobile communication base station, is an interface device for a mobile device to access the internet, and is a form of a radio station, which is a radio transceiver station for information transmission with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area.

The mobile station is one of mobile communication devices, and is connected with the base station through wireless communication.

The lora (long Range radio) network is a long-distance radio, is a long-distance non-cellular low-power-consumption wide area wireless communication network technology, adopts spread spectrum modulation, and has the characteristics of low power consumption and long propagation distance.

Step 102, the mobile station comprises a first data processing module, a first satellite positioning module and a first LORA communication module.

In an example, the first data processing module is an mcu (microcontroller unit) micro control unit or a single chip microcomputer.

The global Navigation Positioning types that the first satellite Positioning module can receive include a beidou satellite Navigation system, a gps (global Positioning system) global Positioning system, a glonass (global Navigation Satellites system) global satellite Navigation system, and a galieo (galileo satellite Navigation system).

The first LORA communication module includes an LORA antenna and an LORA radio frequency module, and is configured to select different adaptive frequency bands according to countries and regions, for example, a 470 + 510Mhz frequency band is adopted in china, where the frequency band has the longest wavelength in all frequency bands and the largest coverage area, and the radius of a circle that can be covered outdoors is 15-20 km. By constructing the LORA application server and the network server, the first LORA communication module can implement LORA communication in a local area network formed by LORA networks.

Step 103, the first satellite positioning module is configured to receive first positioning information from a satellite and first correction information matched with the first positioning information, and the first data processing module is configured to determine the position information of the mobile station according to the first positioning information and the first correction information.

The first satellite positioning module comprises a multi-band satellite receiving antenna and receives first positioning information about the mobile station from a satellite and first correction information matched with the first positioning information, wherein the first correction information comprises time difference, interference information and the like of the first positioning information transmitted by the satellite. It should be understood that a complement refers to a complement of information provided by satellites under the same global navigation positioning type for the same target.

The first positioning information is rectified by the first rectification information, and the position information describing the mobile station can be determined.

And 104, the first LORA communication module is configured to receive the positioning information and the second correction information from the base station, and the first data processing module determines the target positioning of the mobile station based on the location information of the mobile station and the positioning information and the second correction information of the base station.

In order to further improve the accuracy of the position information of the mobile station, the position information of the mobile station is further corrected through the received positioning of the base station and the second correction information, and the target positioning of the mobile station with higher accuracy can be obtained.

And 105, the first LORA communication module is further configured to periodically send the target location to the base station and the cloud database.

In an example, after the mobile station determines a more accurate target location of the mobile station, the target location needs to be sent to the base station and the cloud database through the LORA network, so that the base station can continuously obtain the target location of the mobile station.

It should be understood that the mobile station continuously and intermittently acquires the first positioning information, the first correction information, the positioning information of the base station and the second correction information transmitted by the satellite, thereby continuously determining and transmitting the target positioning of the mobile station,

the utility model provides an outdoor positioning system, set up with LORA network communication connection's mobile station and base station, the mobile station receives the first locating information and the first correction information of satellite, confirm the positional information of self, through the location and the second correction information of the base station that come from the base station and provide, further improve the accuracy of self location, obtain the higher mobile station's of accuracy target location, and send this target location to base station and high in the clouds database, the external location of being convenient for uses the LORA network, coverage is wider, the consumption is lower.

In an example, the base station includes a first base station configured in a LORA gateway mode, the first base station including a second data processing module, a second satellite positioning module, an LTE module, and a second LORA communication module.

The second satellite positioning module is used for receiving second positioning information from a satellite.

The LTE module is used for acquiring a correction information set from a public network, wherein the correction information set comprises second correction information matched with the second positioning information and third correction information of a ground workstation matched with a satellite.

In one example, configuring the base station in the LORA gateway mode enables data forwarding between the mobile station and the public network.

In an example, the second data processing module is an mcu (microcontroller unit) micro control unit or a single chip microcomputer.

The global Navigation Positioning type supported by the second satellite Positioning module includes a Beidou satellite Navigation system, a GPS (global Positioning system), a GLONASS (global Navigation Satellites system) global Navigation system and a Galieo (Galileo satellite Navigation system).

The LTE module includes LTE (long Term evolution), mainly LTE Cat1 wireless module, and can receive Multiple frequency bands of a public network, for example, 15 frequency bands supporting FDD-LTE (frequency Division duplex), TD-LTE 3 frequency bands, W-cdma (wideband Code Division Multiple access) wideband Code Division Multiple access, i.e., 8 frequency bands of a 3G cellular network, and 4 frequency bands of gsm (global System for Mobile communications) global Mobile communication System. Wherein, the supported data rate is 5M or 10M bit/s.

The second LORA communication module includes an LORA antenna and an LORA radio frequency module, and the principle and operation of the specific adapted frequency band are the same as those of the second LORA communication module of the mobile station in step 102, which is not repeated herein and can realize communication with the first LORA communication module of the mobile station through the LORA local area network.

The second satellite positioning module comprises a multi-band satellite receiving antenna for receiving second positioning information from a satellite about a base station, and it should be understood that the second satellite positioning module can also receive second correction information matched with the second positioning information, but because the ground satellite augmentation system not only has the second correction information of the matched satellite, but also has third correction information for describing the position information of a ground workstation matched with the satellite, only the LTE module is used for obtaining a correction information set from a public network through cellular mobile data, namely cellular communication, namely the second correction information and the third correction information, wherein the second correction information comprises time difference and interference information of the second positioning information sent by the satellite, and the like.

Through the second correction information and the third correction information in combination with the second positioning information, the more accurate positioning describing the position of the first base station can be obtained, and the positioning of the first base station and the second correction information are broadcasted through the second LORA communication module, so that other mobile devices in the same LORA network can obtain the information.

In an example, the base station further includes a plurality of second base stations arranged at intervals along the same direction and configured in a bridge mode, and the interval of each base station is set to be smaller than or equal to the radius of the circular coverage area of the LORA network.

According to the radius of the circle covered by the LORA network in the outdoor in step 102, which is 15-20 km, if the radius is 15 km, it can be known that the LORA network belongs to the coverage area of the LORA network within 15 km of the circle centered on the base station, and therefore, only the mobile station located in the coverage area can interact with the first base station in the above steps.

In order to further expand the positioning range of the mobile station outdoors, a plurality of second base stations configured in a bridge mode are arranged along the same direction at intervals by taking a first base station configured in a LORA gateway mode as a starting point. In one example, the first base station has one station with the above functions and modules, and the second base station has multiple stations configured in a bridge mode and only has receiving and forwarding functions. It should be understood that the second base station is able to receive the broadcast of the first base station, i.e. both need to be in the same area covered by the LORA network, and the same spacing condition is also satisfied between the second base station and the second base station, and accordingly, for the purpose of extending the range to the maximum, the spacing between each base station is set equal to the radius of the circle covered by the LORA network.

For example, as shown in fig. 2, it is assumed that there is only one base station, i.e., the first base station, and the first base station broadcasts its own positioning and the second correction information through the LORA network, and all mobile stations with the first base station as the center of circle and within a radius of 15 km can receive the broadcast and can send the target positioning to the first base station; however, the mobile station with the first base station as the center of circle and the radius larger than 15 km cannot receive the broadcast, and cannot transmit the target location to the first base station.

Suppose there is a first base station and a second base station, the first base station broadcasts its own positioning and second correction information, the second base station taking the first base station as the center of circle and having a radius of 15 km can receive the broadcast and forward the broadcast to form a LORA network communication range taking the second base station as the center of circle and having a radius of 15 km, therefore, mobile stations taking the first base station as the center of circle and having a direction pointing to the second base station and a radius of 30 km can receive the broadcast and can transmit their target positioning to the second base station, and the second base station forwards the target positioning of the mobile stations to the first base station. Therefore, compared with the arrangement of only one first base station, the arrangement of the second base station expands the coverage range of the LORA network and supports the positioning of the mobile station in a wider range. By analogy, more second base stations can be arranged, and the coverage area of the LORA network with a wider range can be correspondingly expanded.

In one example, the LORA coverage area of one first base station may support tens of thousands of mobile stations simultaneously. It should be appreciated that in case the accuracy requirements for the positioning of the mobile station are not set, several second base stations may be provided for use as a bridge, as shown in fig. 3. The number and radius are examples, and should be determined by actual conditions, and are not limited in detail.

By using the second base stations in a bridging mode, the coverage area of a single first base station can be wide even in a forest, and all mobile stations in the coverage area can realize the tracking of positioning.

In one example, the determining the target location of the mobile station includes:

In one example, the target location of the mobile station is determined by using Real-time kinematic (RTK) Real-time carrier-phase differential (RTK) technology, and the target location of the mobile station can be calculated by using the RTK technology, where the mobile station itself serves as the location information of the mobile station and the first base station is received as the location of the stationary station through broadcasting, and the second correction information serves as input.

The target of the mobile station is accurately positioned to centimeter level by using RTK technology, so that the user can conveniently and accurately position the mobile station outdoors.

In one example, the determining the location of the base station according to the second location information and the second correction information includes:

In one example, determining the position of the base station is also determining the position of the first base station, using a Real-time kinematic (RTK) Real-time dynamic carrier-phase differential technique, receiving the second positioning information with the base station itself as a station and receiving the second correction information and the third correction information from the public network as a stationary station as inputs, and calculating a position of the base station accurate to centimeter level, i.e. the position of the first base station, by using the RTK.

In one example, the first satellite positioning module comprises:

The global navigation positioning type received by the global navigation positioning receiving module can be preset, if the global navigation positioning type is set to receive satellite data of a Beidou satellite navigation system, the first positioning information is the satellite data given by the Beidou satellite navigation system, and the first correction information received by the correction data receiving chip is also the satellite data given by a satellite which specially provides correction data under the Beidou satellite navigation system.

In one example, the determining the location information of the mobile station includes:

When acquiring corresponding satellite data according to a preset global navigation positioning type, a corresponding positioning correction formula can also be acquired, wherein the positioning correction formula is used for calculating the first positioning information and the first correction information, so that the position information of the mobile station can be determined, and in an example, the positioning accuracy of the current position information of the mobile station is 1 meter level.

In an example, the mobile station is further provided with an emergency call key, and when the emergency call key is triggered, the first data processing module sends identification information configured by the mobile station, the current target location and the current time as messages to the first base station and the cloud database. It should be understood that, according to the step 105, the mobile station periodically transmits the target location to the base station and the cloud database, where the transmission may also include identification information configured by the mobile station and a time corresponding to the target location in addition to the target location, and where the periodic transmission does not interfere with the transmission through the emergency call key.

In one example, as shown in fig. 4, the mobile station includes a first bluetooth module 405, a first battery 406, a first power management chip 407, a first power key/flag key 408, a first USB-C interface 409, and an LED status light 410 in addition to a first satellite positioning module 401, a first LORA communication module 402, a first data processing module 403, and an emergency call key 404.

The mobile station can be connected with the mobile phone through the first Bluetooth module, relevant setting of the mobile station is carried out in the mobile phone app in the form of installing the app in the mobile phone, for example, a brief short message is input into the mobile phone app, and the short message can be sent to the cloud database through the first LORA communication module of the mobile station.

The first power key and the mark key can be independent individuals or combined into a first power key, when the first power key is pressed for a long time, the power function of controlling the switch of the mobile station is executed, when the first power key is pressed for a short time, the power key can be used as a mark, when the first power key is pressed for a short time, the automatic mark serial number (the current serial number is the serial number of the last time plus 1) is used for storage, and the serial number, the corresponding current time and the target positioning at the corresponding current time are stored in a data line form for subsequent processing or drawing, such as outdoor movement route detection identification and road book drawing, geological survey of geological prospecting personnel, forest or mine resource marking of agriculture and forestry departments. Similarly, each time the mobile station moves and the target location is changed, the sequence number, the corresponding current time and the target location at the corresponding current time are stored in the form of a data line, and the mark of the sequence number is incremented by 1 as described above.

When the emergency call key is triggered, the first data processing module takes the identification information configured by the mobile station, the current target location and the current corresponding moment as messages and sends the messages to the first base station and the cloud database. It should be understood that each mobile station is configured with identification information for determining the identity of the mobile station to which the identification information corresponds and the person carrying the mobile station when the base station receives the message.

The first USB-C interface may be used to charge the mobile station and may also be used to connect a computer to derive from the storage of the mobile station the time of the storage in the form of a data line and the corresponding target location.

The LED status light is used to prompt the working status of the mobile station, such as a warning module, a marking module, a charging mode, and an electric quantity prompt, and the specific function should be set according to the actual use, which is not limited herein.

Meanwhile, the wireless module is also connected to an external public network through a wireless signal and is used for acquiring an NTRIP (network Transport of RTCM via Internet protocol), namely a protocol for performing RTK data transmission on the Internet, from the public network, and the SIM card seat is used for being inserted into a local mobile card where the first base station is located to realize the cellular communication through the connection of cellular mobile data and the public network. It should be appreciated that the arrangement of the wireless module and the SIM card holder are complementary to the LTE module, such that the first base station has multiple ways to interface with the public network to obtain the set of remediation information.

The second USB-C interface is used for charging, importing and exporting data and upgrading setting inside the first base station.

The second power key has two operation modes including a mode in which a long press is performed to implement a power-on function and a mode in which a short press is performed to implement a voice dialing or hang-up function.
