The operation method of the narrow-linewidth tunable laser system includes the steps that after being initialized, the microcontroller transmits preset default data frames to the laser, the data frames returned by the laser are read, the situation that the data frames have no error is determined, whether power failure occurs or not is detected at regular time, updated instructions of the host are received and transmitted to the laser, and the current working state information of the laser is transmitted to the host. The system only needs to be powered up by a single power supply and can be used easily in an embedded mode. A tuning control interface of the host is simple and visual, and reliable operation is guaranteed through power failure self-detection.

The invention discloses a resource management method for vehicle-vehicle communication trackside equipment based on multi-locking mechanism. The resource management method comprises the following steps: when vehicle-mounted equipment detects that movement authority extends to a turnout and the locking position of the turnout is matched with an operation plan of a train, sending a turnout locking command to an OC; if the turnout for the train is locked at present when the turnout locking command is locked by the OC, superposing a locking command to the existing locking state, feeding the finishing information of the locking of the turnout back to the vehicle-mounted equipment; and finally, after the finishing response of the locking of the turnout is received by the vehicle-mounted equipment, allowing the movement authority to extend across the turnout. By utilizing the multi-locking mechanism, the resources are shared by multiple vehicles, the vehicle-vehicle tight tracking is realized, the train is in a safe state when passing through the trackside equipment by virtue of sequential mutual exclusion execution strategies of an operation command and a locking command, and the resources are no longer authorized to another vehicle-mounted equipment in an operable state, so that the safety is guaranteed.
