A method, device, computer equipment and storage medium for GNSS time synchronization are disclosed. The method includes: receiving data packet of NMEA protocol, reading a valid UTC time from data packet of NMEA protocol, and storing the read valid UTC time in a time synchronization controller; receiving PPS signal, capturing a local time output by local clock when PPS signal is generated, and storing the local time in the time synchronization controller; reading a last local time stored before the current local time and reading the stored latest UTC time as a UTC time corresponding to the last local time when the time synchronization controller receives the current local time; and determining, by the time synchronization controller, a local time correction amount according to the last local time and the UTC time corresponding to the last local time, and correcting the local clock according to the local time correction amount.

Method, device, equipment and storage medium for global navigation satellite system time synchronization

A sensor configuration method, an apparatus, computer equipment and a storage medium are disclosed. The method includes acquiring connection configuration information generated based on user input, querying for a target sensor driver matched with a target sensor represented by the sensor identifier in a device driver set, calling a target communication port driver matched with the target communication port represented by the communication port identifier and establishing communications with the target sensor by the target sensor driver and the target communication port driver. The connection configuration information includes a sensor identifier and a communication port identifier. The device driver set is pre-stored with a number of sensor drivers corresponding to a number of sensors.
