S4: after the Bluetooth system of the unlocked GNSS receiver detects that the successfully matched Bluetooth terminal leaves the preset searching range, the unlocked GNSS receiver is locked, so that the unlocked GNSS receiver is converted into the locked GNSS receiver.
It can be understood that when the successfully matched bluetooth terminal leaves the preset search range, the bluetooth system of the GNSS receiver cannot acquire bluetooth identification data, and cannot perform matching, i.e. disconnect bluetooth connection with the bluetooth terminal, so that after the successfully matched bluetooth terminal is detected to leave the preset search range, the unlocked GNSS receiver is locked, and is converted into an unmodified state again.
After step S4, the method further comprises: step S1 is executed, so that the GNSS receiver is locked and unlocked by automatic circulation.
According to the method, after the Bluetooth system of the GNSS receiver detects Bluetooth identification data sent by the Bluetooth terminal entering the preset search range, the Bluetooth identification data is matched with preset Bluetooth registration data, so that whether a specific Bluetooth terminal is in the preset search range or not is detected, the GNSS receiver is automatically locked and unlocked, the operation is simple and efficient, the working state and the working data of the GNSS receiver can be safely, efficiently and conveniently protected by operators, and engineering loss caused by physical misoperation, personnel misoperation and even malicious operation is reduced.
The above is a detailed description of one embodiment of a locking and unlocking method for a bluetooth based GNSS receiver provided by the present invention, and the following is a detailed description of another embodiment of a locking and unlocking method for a bluetooth based GNSS receiver provided by the present invention.
Referring to fig. 2, the locking and unlocking method of a bluetooth-based GNSS receiver provided by the present invention includes:
s0: registering Bluetooth identification data of the Bluetooth terminal in a white list in a Bluetooth system of the GNSS receiver as unique Bluetooth registration data, wherein the Bluetooth identification data comprises a Bluetooth terminal name and/or a Bluetooth mac address;
it should be noted that, the white list is empty under factory setting of the GNSS receiver, and when the bluetooth terminal of the user, such as a mobile phone, a computer, etc. with bluetooth function, enters the search range of the bluetooth system of the GNSS receiver, the bluetooth system of the GNSS receiver is in inductive and pairing connection with the bluetooth terminal.
The user can register the Bluetooth identification data of the Bluetooth terminal in a white list in the Bluetooth system of the GNSS receiver as unique Bluetooth registration data in a configuration interface of the Bluetooth system to be used as a unique verification condition required to be matched with subsequent Bluetooth identification data so as to ensure the uniqueness of the user. Meanwhile, the bluetooth identification data is also unique data, and is generally a bluetooth terminal name and/or a bluetooth mac address.

Further, step S0 further includes:
s10: the method comprises the steps that through judging whether a white list in a GNSS receiver is in a registered state or an unregistered state, when judging that the white list is in the registered state, unbinding processing is carried out on registered Bluetooth registration data in the white list, so that the white list is converted into the unregistered state; when the white list is in an unregistered state, step S0 is re-performed.
It can be understood that, because the unique bluetooth registration data is used as the unique verification condition to be matched with the subsequent bluetooth identification data, when the bluetooth terminals of other users need to be replaced, whether the whitelist is in a registered state needs to be judged, if so, the registered bluetooth registration data needs to be unbinding, so that the whitelist is converted into an unregistered state, namely a blank state, and then the whitelist is registered according to the step S0, so as to ensure the unlocking and locking security.
The above is a detailed description of another embodiment of a locking and unlocking method for a bluetooth based GNSS receiver provided by the present invention, and the following is a detailed description of one embodiment of a locking and unlocking system for a bluetooth based GNSS receiver provided by the present invention.
