[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202410157436.5 filed in China on February 4, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of satellite positioning technology, and in particular to a bump-and-flash connection technology for an RTK host and a hand controller. Background Art

[0004] A real-time kinematic (RTK) receiver system typically consists of two components: an RTK host and a controller. During operation, the RTK host must establish a connection with the controller via Bluetooth or WiFi. However, this connection requires the user to manually operate the controller, searching for Bluetooth or WiFi, and then manually clicking on it to establish a connection with the RTK host, which is somewhat inconvenient.

[0005] In addition, the RTK host and controller can also use Near Field Communication (NFC) to trigger a connection between the controller and the RTK host. This method requires both the controller and the RTK host to support NFC. When an NFC-enabled controller is brought close to the RTK host, the controller acquires Wi-Fi information based on the transmitted NFC data, establishing a Wi-Fi connection between the RTK host and the controller.

[0006] However, for the RTK host and handheld controller that do not have NFC function, the above automatic connection application scenario cannot be realized.

[0007] Therefore, there is an urgent need for an automatic connection solution between the RTK host and the hand controller.

[0008] Summary of the Invention

[0009] The purpose of this application is to provide a method for connecting an RTK host and a hand controller by knocking the hand controller against the RTK host for automatic connection, thereby improving the convenience of user connection. At the same time, the RTK status can be sensed in advance before the connection, making it convenient for the user to select the appropriate operation mode in advance, thereby enabling fast operation.

[0018] In another preferred embodiment, the step of configuring the working mode of the handheld according to the RTK status information includes the following sub-steps:

[0020] If the network status of the RTK host is abnormal, the user is prompted whether to switch the communication network;

[0021] The communication network is configured according to the user's selection.

[0026] In another preferred embodiment, the RTK host detects whether a collision event occurs based on acceleration information measured by an IMU built into the RTK host.

[0027] In another preferred embodiment, the step of receiving the broadcast information by the handheld device includes the following sub-steps:

[0028] The wristband detects whether a collision occurs;

[0029] When the wristband detects a collision event, it receives Bluetooth broadcast information.

[0030] In another preferred embodiment, the wristband detects whether a collision event occurs based on acceleration information measured by an IMU built into the wristband.

[0031] In another preferred example, the RTK host has a built-in inertial navigation module, a Bluetooth module and a WiFi module.

[0051] In the following description, many technical details are provided to help readers better understand this application. However, those skilled in the art will understand that even without these technical details and the various changes and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be implemented.

[0052] Description of some concepts:

[0053] Inertial Measurement Units (IMUs) and inertial navigation modules are sensors used to detect and measure acceleration and rotational motion. The most basic inertial sensors include accelerometers and angular velocity meters (gyroscopes).

[0054] A handheld controller, also known as a handbook, is an industrial-grade rugged phone with buttons. It is generally equipped with an Android system and has a surveying and mapping APP installed. It communicates with a mobile station receiver via Bluetooth or WiFi. The handheld APP generally performs measurement operations, saves measurement data and drawings, and can also send instructions to the mobile station receiver for different measurement services.

[0055] RTK host: RTK mobile station receiver.

[0056] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0057] The first embodiment of the present application relates to a bump-and-flash connection method for an RTK host and a hand controller. FIG1 is a flow chart of the bump-and-flash connection method for an RTK host and a hand controller.

[0058] In this embodiment, preferably, the RTK host has a built-in inertial navigation module, a Bluetooth module, and a WiFi module. The handheld also has a built-in inertial navigation module, a Bluetooth module, and a WiFi module.

[0059] Specifically, as shown in FIG1 , the method for connecting the RTK host and the controller by collision and flash includes the following steps:

[0060] In step 101, when the RTK host detects a collision event, it sends a broadcast message via Bluetooth. The broadcast message includes the device serial number information and RTK status information of the RTK host. The device serial number information corresponds one-to-one with the WiFi information of the RTK host. The RTK status information includes satellite status information, network status information, and fixed solution status information.

[0061] In this embodiment, preferably, in the above step 101, the RTK host detects whether a collision event occurs based on acceleration information measured by an IMU or inertial navigation module built into the RTK host.

[0062] Then, the process proceeds to step 102 , where the handheld receives the broadcast information and parses the WiFi information and the RTK status information in the broadcast information.

[0063] In this embodiment, preferably, the step of "the handheld receiving the broadcast information" may further include the following sub-steps:

[0064] The wristband detects whether a collision occurs;

[0065] When the wristband detects a collision event, it receives Bluetooth broadcast information.

[0066] Furthermore, preferably, the wristwatch detects whether a collision event occurs based on acceleration information measured by an IMU or inertial navigation module built into the wristwatch.

[0067] Then, the process proceeds to step 103 , where the handheld establishes a WiFi connection with the RTK host according to the WiFi information, and configures the working mode according to the RTK status information.

[0068] In this embodiment, preferably, the step of configuring the working mode of the handheld controller according to the RTK status information may further include the following sub-steps:

[0069] The handheld controller determines whether the satellite search status of the RTK host is normal according to the satellite status information;

[0070] If the satellite search status of the RTK host is abnormal, the user is prompted to switch the satellite base.

[0071] It should be noted that the satellite status information here mainly includes: whether satellites are found, and the number of satellites found.

[0072] If the satellite search status is abnormal, that is, no satellites are found or the number of satellites found does not meet the requirements, the user will be prompted to switch the satellite base. For example, the user can be prompted to move to an open area for operation.

[0073] In this embodiment, preferably, the step of configuring the working mode of the handheld controller according to the RTK status information may further include the following sub-steps:

[0074] The handheld controller determines whether the network status of the RTK host is normal according to the network status information;

[0075] If the network status of the RTK host is abnormal, the user is prompted whether to switch the communication network;

[0076] The communication network is configured according to the user's selection.

[0077] It should be noted that the network status information here refers to whether it is possible to connect to the communication network and the signal status of the communication network.

[0078] If the user cannot connect to the communication network or the signal of the communication network is weak, the user may be prompted to switch to another communication operator.

[0079] In this embodiment, preferably, the step of configuring the working mode of the handheld controller according to the RTK status information may further include the following sub-steps:

[0080] The handheld controller determines whether the RTK host is in a fixed solution state according to the fixed solution state information;

[0081] If the RTK host is not in a fixed solution state, the user is prompted whether to switch the working mode;

[0082] The working mode is configured according to the user's selection.

[0083] It should be noted that the fixed solution states here include: single-point solution state, floating-point solution state, and fixed solution state. The positioning accuracy of these three states increases in sequence. Generally, the RTK receiver needs to operate in the fixed solution state.

[0084] Then, the process proceeds to step 104, where the RTK host enters a corresponding working mode according to the configuration of the handheld controller.

[0085] This process ends thereafter.

[0086] In this embodiment, when the RTK host sends Bluetooth broadcast information, it also sends the satellite status, network status and / or fixed solution status together. Then, based on the received Bluetooth broadcast information, the handheld will determine in advance whether it can operate directly after connecting to the RTK host. If the direct operation conditions are not met, the user will be asked to select the appropriate network and working mode in advance, and after the WiFi connection is made, it will be directly configured to the appropriate operating state, thereby achieving fast operation and improving work efficiency.

[0087] In summary, the bump-and-flash connection method for the RTK host and the hand controller disclosed in the embodiment of the present application improves user convenience by automatically connecting by bumping the RTK host with the hand controller. At the same time, the RTK status can be sensed in advance before the connection, which facilitates the user to select the appropriate operation mode in advance and achieve fast operation.

[0088] In order to better understand the technical solution of this specification, it is described below in conjunction with a preferred embodiment. The details listed in the preferred embodiment are mainly for ease of understanding and are not intended to limit the scope of protection of this application.

[0089] The technical solution of this preferred embodiment includes the following steps:

[0090] (1) RTK host has built-in inertial navigation module, built-in Bluetooth and WiFi module;

[0091] (2) When the inertial navigation module of the RTK host senses a collision, it broadcasts the serial number (WiFi SSID), satellite search status, network status, and fixed solution status of the RTK host via Bluetooth (BLE broadcast);

[0092] (3) After receiving the broadcast, the handheld analyzes the WiFi name corresponding to the serial number and actively establishes a connection;

[0093] (4) When the handheld controller establishes a connection with the RTK host, it determines whether the connected RTK host can directly operate based on the received satellite search status, network status, and fixed solution status;

[0094] (5) If the satellite search status is normal, the network is normal, and the satellite is fixed normally, there will be no prompt;

[0095] (6) If any conditions are not met, the controller will prompt the user when connecting and prompt the user to switch according to the current environment.

[0096] In this preferred embodiment, the user taps the RTK host to broadcast its information, triggering the controller to connect. The RTK host also broadcasts information about satellite status, network status, and fixed solution status in its Bluetooth broadcast. This notifies the user of the current RTK status before connecting, guiding them through 4G mode switching and satellite-based switching, improving connection convenience. Furthermore, the RTK status is detected before connection, enabling faster operation.

[0100] 2. After receiving the Bluetooth broadcast, the controller parses the broadcast information to obtain the RTK host's WiFi information and RTK status information.

[0107] 3. Send a Bluetooth broadcast. The broadcast package contains WiFi information and RTK status information.

[0108] The process on the RTK controller side includes:

[0109] 1. When not connected to the RTK host, the RTK controller detects collisions in real time (based on the controller's internal IMU) and attempts to receive broadcast information when a collision is detected.

[0110] 2. Receive broadcast information and parse the WiFi information and RTK status information in the broadcast;

[0111] 3. Actively connect to the WiFi, prompt the user based on the status information, and guide the customer to select the appropriate network, satellite base, etc.

[0115] 3. Establish a connection using the handheld device.

[0116] In this preferred embodiment, the RTK host and the hand controller are automatically connected by knocking the hand controller against the RTK host (without the user operating the hand controller). At the same time, the user can be informed of the RTK status in advance before the connection, so that the user can select the appropriate operation mode in advance.
