Description

Technical Field

[0001] The present invention relates to the technical field of sightseeing vehicles, and particularly relates to an anti-collision system for rail sightseeing vehicles. Background Art

[0002] With the advent of the operation era of the concept of all-for-one tourism, the passenger flow in scenic spots has increased, and the number of vehicles on a single track also needs to increase accordingly. Among them, the anti-collision problem between vehicles becomes particularly important. In the past, photoelectric reflection switches and radars installed in the front and rear of vehicles were used as anti-collision function vehicles, which would generate collision risks and false stop actions when facing turning and meeting situations. And the cost of arranging wireless relay nodes along the track and arranging radio frequency modules for positioning is relatively high, the maintenance is inconvenient, and when the vehicle is running and switching wireless relay nodes, there is a communication delay, and the blind area during this period is likely to cause corresponding collision risks; Therefore, there is an urgent need in the industry for a new type of anti-collision system for rail sightseeing vehicles. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti-collision system for rail sightseeing vehicles to solve the problem of rear-end collision or collision when multiple existing vehicles run on a single track.

[0004] The present invention first provides an anti-collision system for rail sightseeing vehicles, including a data analysis and calculation unit, a positioning and calibration unit, a displacement data acquisition unit, a wireless communication unit, a human-computer interaction unit, a battery life unit, and an anti-collision alarm unit; the positioning and calibration unit, the displacement data acquisition unit, the wireless communication unit, the human-computer interaction unit, and the anti-collision alarm unit are respectively connected to the data analysis and calculation unit; the displacement data acquisition unit is arranged on the sightseeing vehicle, and the positioning and calibration unit is arranged on the running track of the sightseeing vehicle. When the sightseeing vehicle passes through the positioning and calibration unit of the track, it can know the position of the vehicle on the entire running track, which is used as the position calibration point of the vehicle itself. At the same time, the displacement data acquisition unit provides the displacement data of the sightseeing vehicle. The displacement acquisition unit and the positioning and calibration unit provide vehicle displacement and calibration signals to the data analysis and calculation unit, and the displacement data of the vehicle relative to the calibration point on the track is obtained through calculation; the wireless communication unit provides data exchange between vehicles, receives external signals, and sends signals of the vehicle itself; the human-computer interaction unit is used for setting the entire track, vehicle number, anti-collision interval, and anti-collision strategy, displaying the position data of nearby vehicles, and prompting the operation status of the vehicle system; the anti-collision alarm unit is connected to the vehicle control system of the vehicle itself, outputs an alarm signal to the vehicle control system, and the vehicle control system controls deceleration or parking according to the setting of the anti-collision interval; the battery life unit independently powers the entire anti-collision system to ensure that the anti-collision system can work normally when the vehicle is powered off, and ensure that other vehicles know the position of the vehicle.

[0005] Further, the anti-collision area includes a primary anti-collision area and a secondary anti-collision area. The distance of the primary anti-collision area is less than that of the secondary anti-collision area; and there is a vehicle executing the primary anti-collision strategy within the primary anti-collision area, and a vehicle executing the secondary anti-collision strategy within the secondary anti-collision area.

[0006] Further, the distance range of the primary anti-collision area is less than 200m, and the distance range of the secondary anti-collision area is 200 - 500m.

[0007] Further, the displacement data acquisition unit is a Hall sensor. The Hall sensor is installed at the passive wheel of the sightseeing vehicle to count the rotation pulses of the wheel.

[0008] Further, the number of installed Hall sensors is not less than three, and they are respectively installed at the three passive wheels of a sightseeing vehicle.

[0009] Further, the positioning and calibration unit is a metal induction block fixedly installed on the track.

[0010] Further, the wireless communication unit uses short message communication, and the short message communication has a check code to ensure the accuracy of the received and sent data.

[0011] Further, the data analysis and calculation unit is a controller.

[0012] Beneficial effects:

[0013] The anti-collision system for a rail sightseeing vehicle of the present application device includes a data analysis and calculation unit, a positioning and calibration unit, a displacement data acquisition unit, a wireless communication unit, a human-machine interaction unit, a battery endurance unit, and an anti-collision alarm unit; by setting a positioning and calibration unit on the track and a displacement data acquisition unit on the sightseeing vehicle, the position of the vehicle relative to the track calibration point can be calculated. Through the wireless communication unit, the reception and transmission of position information between vehicles can be realized, and the relative positions between vehicles can be known. By presetting the anti-collision area and anti-collision strategy through the human-machine interaction unit, the anti-collision alarm unit can output an alarm to the vehicle control system of the sightseeing vehicle to execute corresponding deceleration operation measures and / or braking stop measures to prevent the sightseeing vehicles from colliding with each other; at the same time, the battery endurance unit is set to supply power to each unit of the anti-collision system separately, so that the anti-collision system can continue to work when the sightseeing vehicle loses power, ensuring that other vehicles know the position of the vehicle and preventing the risk of collision.

[0014] The displacement data acquisition unit of the device in this application selects Hall sensors. By respectively installing one Hall sensor on multiple passive wheels of the sightseeing vehicle, it can cooperate with the data analysis and calculation unit to self-check the anti-collision system of the vehicle. By calculating and comparing the pulse numbers of the Hall sensors at multiple passive wheels, it is judged whether there is a large deviation in the pulse numbers. If the pulse number of the Hall sensor has a large deviation, it is judged as abnormal. At the same time, it can also judge whether there is a deviation in the position when the sightseeing vehicle passes through the track calibration point each time. When the deviation reaches a certain value, it can be judged that the wheels of the sightseeing vehicle are severely worn, and the maintenance personnel are reminded to perform vehicle maintenance.
