Abstract: Disclosed are a data processing method and apparatus, and a server. The method comprises: distributing data records in a database to buckets, and setting an expiration time; determining a bit corresponding to any data record, and setting the bit value of the corresponding bit to be a second value; when a load request regarding new data is received, identifying a target data bucket and a bit, in the target data bucket, corresponding to the new data, and determining, by means of determining whether the bit value of the corresponding bit is the second value, whether to write the new data into the target data bucket; and if no new data is written into the data bucket before the expiration time is reached, deleting the data bucket and the data records therein when the expiration time is reached, otherwise, prolonging the expiration time. A data duplication determination range is narrowed down by means of distributing data to buckets, and data in some buckets gradually expires because the data is no longer active, such that the aim of data deletion is achieved, thereby solving the problem of an increasing false positive rate during data duplication determination.

Abstract: The present invention provides a neutral zone passing control method for a train. A neutral zone passing control apparatus obtains a train position signal, and when it is determined, on the basis of the train position signal, that a train travels to an early warning point, sends a force unloading forecast signal to a vehicle-mounted control apparatus; and the vehicle-mounted control apparatus receives the force unloading forecast signal and controls, in response to the force unloading forecast signal, the train to reduce the traction force from a first traction force to a second traction force before traveling to a commutation point. On the basis of the neutral zone passing control method for a train provided in the present invention, before the train travels to the commutation point, the traction force is reduced from the first traction force to the second traction force, and when the train arrives at the commutation point, the impact generated by instantaneous force unloading of the second traction force due to power loss is smaller than the impact generated by instantaneous force unloading of the first traction force, so that an impulse of the train is alleviated, and the train can safely and smoothly pass through a neutral zone.
