Problems solved by technology

Because pipeline traffic often shuttles inside buildings, and satellite positioning technologies such as GPS are difficult to achieve signal coverage, and metal materials on the track will also affect the reception of satellite signals, traditional positioning methods have obvious defects

Embodiment 1

[0026] Such as figure 1 As shown, the automatic driving auxiliary braking system of the circular pipe rail small vehicle based on RFID positioning described in this embodiment includes a small vehicle and a track, and the chassis of the small vehicle is provided with an RFID card reader whose reading direction is downward. An RFID tag group is provided on the base surface of the track, and it is ensured that the RFID card reader can pass directly above the RFID tag when the vehicle is running. The system is connected, and RFID tag groups are set at intervals in the track section, at least the distance between two groups of RFID tag groups is less than the distance between other RFID tag groups, and the number of RFID tags in the RFID tag group is related to the speed of the vehicle passing Proportional. The RFID tags in the RFID tag group contain the same information.

Abstract

The invention relates to an automatic driving auxiliary braking system for a loop-pipe-track small vehicle based on RFID positioning. The system comprises the small vehicle and a track; a chassis of the small vehicle is provided with an RFID card reader with a downward reading direction, the base surface of the track is provided with RFID tag groups, and it is ensured that the RFID card reader canpass through the portion over RFID tags when the vehicle runs; the RFID card reader is connected with a vehicle-mounted intelligent terminal, the vehicle-mounted intelligent terminal is connected with a vehicle body brake control system, the RFID tag groups are arranged on segments of the track at intervals, the distance between at least two RFID tag groups is smaller than the distance among theother RFID tag groups, and the quantity of the RFID tags in the RFID tag groups is directly proportional to the passing speed of the vehicle. Through the structure, the automatic driving system of thepipe-track vehicle can provide a multi-stage deceleration braking scheme for arrival parking, braking decision assistance information is provided for the vehicle, and finally, stable and precise parking is achieved.

Description

technical field [0001] The present invention relates to the automatic driving auxiliary braking system of vehicles in pipeline rail traffic, in particular to the field of automatic driving auxiliary braking of pipeline rail vehicles using RFID positioning technology, and in particular to the automatic driving assistance of circular pipeline rail small vehicles based on RFID positioning Braking System. Background technique [0002] With the continuous improvement of people's requirements for travel quality, new transportation methods continue to emerge, among which tube-rail transportation has attracted widespread attention. The tube-rail transportation is an overhead track network that gradually extends along both sides of the existing road, fully connects buildings and the ground, and operates smart small vehicles in an unmanned manner. Since the tube-rail platform is generally small and located in the air, precise braking and parking are extremely important when approachi...
