Embodiment Construction

[0112] As mentioned above, in order to ensure that accurate positioning information can be obtained after the train is awakened, the on-board core equipment is used to store the positioning information before the train goes into sleep mode, and the on-board core equipment is normally powered on during the train's sleep mode, so that the on-board The core device can monitor the motion of the train during the sleep mode, and update the stored positioning information according to the monitored motion, so that the latest positioning information can be obtained from the on-board core device after the train wakes up. Since the on-board core equipment is always in the motion monitoring state when the train is in sleep mode, in order to ensure that the listed on-board core equipment can be powered normally during the sleep mode, it is necessary to install a battery with a large volume and weight on the train, which will increase the train’s Self-weight and reduce the available space of...

Abstract

The invention provides a train positioning method, device and system and a computer readable medium. The train positioning method comprises the steps: acquiring first equipment identification information received by at least one first receiving antenna; acquiring positioning information of the train; after it is determined that the first device identification information is credible, storing the first device identification information and the positioning information in a nonvolatile memory; after the train is awakened from the sleep mode, receiving second equipment identification information by utilizing at least one receiving antenna; according to the received second equipment identification information and the first equipment identification information read from the nonvolatile memory, judging whether the train is located at the position before the train enters the sleep mode after being awakened; if it is determined that the awakened train is located at the position before the trainenters the sleep mode, determining that the current position and direction of the train are matched with the positioning information stored in the nonvolatile memory, and completing the positioning of the train. According to the scheme, the use experience of train users can be ensured.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a train positioning method, device, system and computer readable medium. Background technique [0002] Fully Automatic Operation (FAO) is a train operation mode in which the train operation is completely controlled by the automatic control system, which can realize the automatic start, automatic operation, fixed-point parking of the train, fully automatic driving, automatic return, and automatic entry and exit of the train. It is widely used in train control in urban subways, high-speed railways and other rail transit. Fully automatic driving needs to be realized based on train positioning, that is, the train needs to be positioned before the train starts and during the train operation, and then the automatic control system can automatically control the train according to the position of the train. [0003] Fully automatic driving trains will enter the dormant are...
