Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle positioning technology, in particular to a positioning control system for a narrow-gauge tourist passenger train. BACKGROUND

[0002] With the development of science and technology and the progress of society, there are some traditional resource mining areas that are closed down and transformed into high-quality tourist areas after repair. Due to their special historical background, the main traffic mode in these areas is often a narrow-gauge mine track.

[0003] In order to make full use of existing traffic resources, narrow-gauge tourist passenger trains have emerged. However, most of these areas are mountainous terrains with many caves and tunnels, complex road networks, numerous interconnecting branch lines, high and low altitude platforms with the same latitude and longitude, and were built relatively early. Therefore, it will be very costly to modernize the signal system of the narrow-gauge tourist passenger trains in such areas.

[0004] The positioning methods commonly used in domestic and foreign signal systems, such as GPS positioning, cannot meet the positioning needs of train operation and management in tourist passenger trains due to their limitations. SUMMARY

[0016] When the vehicle enters or exits the beacon-only area without GPS, double beacons with a preset distance are arranged at the entrance and the exit, respectively.

Of course, they are only examples, and the purpose is not to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.

[0055] In order to use the narrow-gauge railway in special geographical environments such as mines and mountainous areas, narrow-gauge tourist passenger vehicles are applied, but the cost of transforming the current rail transit signal in these special geographical environments is high, so Figure 1 , the present application designs a new positioning control system for narrow-gauge tourist passenger vehicles, which uses trackside beacons 300, beacon readers 200 and GPS global positioning functions to build a precise positioning vehicle in full network and full working conditions.

[0056] In some embodiments of the present application, referring to Figure 1 , the positioning control system includes a controller 100, a plurality of beacons 300, a beacon reader 200 and a GPS antenna 400.

[0057] The beacon 300 involved in the present application is an electronic tag based on a radio frequency chip, which has a unique number, and different beacons 300 have different encodings.

[0058] The beacon reader 200 is installed on the vehicle and is used in cooperation with the beacon 300. After the beacon reader 200 senses the beacon, it can obtain the number of the beacon through wireless transmission, and the controller 100 stores the encoding of all beacons and the installation position information of each beacon, such as the distance from the road sign, the latitude and longitude information.

[0059] According to the line condition and the line use scene, a plurality of beacons 300 can be arranged beside the track in advance. When the vehicle passes along the track, the beacon reader 200 can scan the beacon 300 to obtain the corresponding code and installation position information of the beacon 300.

[0060] The beacon 300 can be arranged in the center of the track to facilitate the scanning of the beacon reader 200.

[0061] The beacon 300 has the risk of damage and loss, and therefore, in the present application, the beacon 300 and the GPS signal are combined to perform positioning.

[0062] The controller 100 is internally provided with the number of all beacons 300, the installation position information of each beacon 300, and the road network map, which can be uniformly managed by the upper computer software.

[0063] A database file can be established in the controller 100 to store the number of all beacons 300, the installation position information of each beacon 300, and the road network map. The number of all beacons 300, the installation position information of each beacon 300, and the road network map can also be stored in a storage file (not shown) connected to the controller 100.

[0064] In order to accurately position different routes, in some embodiments of the present application, the route is divided into regions according to the beacon signal and the GPS signal.

[0065] The route between every two beacons 300 is a region, and no beacon 300 is arranged in the region.

[0066] The region information includes whether the GPS signal is reliable in the region defined between every two beacons 300, whether the region contains a station, and whether the station needs to be reported.

[0067] The road network map is the region information.

[0068] In some embodiments of the present application, the beacon that limits the start of entering the region can be referred to as a start beacon, and the beacon that limits the exit of the region can be referred to as an end beacon.

[0069] The latitude and longitude information corresponding to the start beacon is the starting position of the region, and the latitude and longitude information corresponding to the end beacon is the end position of the region.

[0070] When the obtained vehicle position is between the starting position and the end position, it indicates that the vehicle is located in the region.

[0071] In some embodiments of the present application, in order to realize accurate positioning of the vehicle in a complex geographical environment, according to the route condition, the road network map is divided into a GPS priority region, a beacon priority region, and a beacon-only region without GPS.

[0072] In the GPS priority area as described above, although there are GPS positioning signals and beacon positioning signals, the GPS positioning signals are dominant in this area.

[0073] The GPS priority area is used in the area under the scenario of frequent demand for reversing and pulling trains in stations and the like.

[0074] In the beacon priority area as described above, although there are GPS positioning signals and beacon positioning signals, the GPS signals can be weak and not reliable or the GPS signals can be strong and reliable, so the beacon positioning signals are dominant in this area.

[0075] The beacon priority area is used in the area where the GPS signals are weak or the GPS errors are large in a line in a valley and the like.

[0076] In the only beacon without GPS area as described above, the GPS signals are not considered and only the beacon positioning signals are used.

[0077] The only beacon without GPS area is used in the area without GPS signals such as a tunnel or a cave.

[0078] As follows, each area will be described respectively.

[0079] In the GPS priority area, the controller 100 receives the GPS positioning information (i.e., the latitude and longitude information) in real time through the GPS antenna 400 and obtains the real-time position, the real-time speed, and the running direction of the vehicle.

[0080] In this area, the GPS accuracy is high enough, after the vehicle scans the starting beacon of the area and enters the area, the system reaches the specified position according to the GPS positioning information and the pre-stored GPS positioning comparison of the station position, and the controller 100 controls the vehicle PIDS (passenger information display system) system 500 to broadcast the station or the scenic spot through network communication.

[0081] Among them, the vehicle PIDS system 500 is an existing rail transit signal subsystem and is an output device for station display and station announcement.

[0082] In the GPS priority area, the vehicle does not trigger the corresponding output signal after triggering the beacon 300 multiple times when reversing and pulling the train.

[0083] In order to make the vehicle know when to enter the GPS priority area, a starting beacon 300 indicating the entry into the GPS priority area needs to be arranged before entering the GPS priority area.

[0084] When the beacon reader 200 scans the start beacon 300 and acquires the code corresponding to the start beacon 300, the vehicle considers that it has entered the GPS priority area, and at this time, the positioning signal is mainly the GPS positioning signal.

[0085] If the GPS positioning information received by the vehicle exceeds the installation position information corresponding to the start beacon 300, it is determined that the vehicle has entered the GPS priority area, otherwise, the vehicle has not entered the GPS priority area.

[0086] After the vehicle enters the GPS priority area, if the beacon reader 200 does not scan the start beacon 300, it is considered that the start beacon 300 is damaged, and the start beacon 300 failure can be recorded and fed back to the driver for processing.

[0087] In the GPS priority area, there is a special case, there is a section of uphill railway, and there are a station at the foot of the mountain and a station on the mountain, the two stations have very close longitude and latitude, but different altitudes, and the controller 100 determines different stations according to different beacons 300 scanned.

[0088] In some embodiments of the present application, in order to enable the vehicle to know when to exit the GPS priority area, an end beacon 300 indicating the exit of the GPS priority area is arranged before the vehicle needs to exit the GPS priority area.

[0089] When the vehicle exits, the beacon reader 200 scans the end beacon 300, and the vehicle considers that it has exited the GPS priority area, and switches the working mode according to the type of the next area.

[0090] For example, if the type of the next area is a beacon priority area, the working mode corresponding to the beacon priority area (which will be introduced below) is switched to, if the type of the next area is a beacon only no GPS area, the working mode corresponding to the beacon only no GPS area (which will be introduced below) is switched to.

[0091] Among them, the end beacon of the previous area is the start beacon of the next area.

[0092] In some embodiments of the present application, the vehicle will also automatically exit the GPS priority area after the GPS positioning information of the vehicle shows that the vehicle has left the GPS priority area by a distance (for example, 50 meters).

[0093] In this case, it indicates that when the vehicle actually exits the GPS priority area, the beacon reader 200 does not scan the end beacon 300 indicating the exit of the GPS priority area, in this case, the end beacon 300 may be faulty or damaged, therefore, the end beacon 300 failure can be recorded and fed back to the driver for processing.

[0094] For example, when exiting a GPS priority area and entering a beacon priority area, since the beacon priority area is a GPS untrusted road segment, but occasionally a strong GPS signal (i.e., a trusted GPS signal) can be received, when a trusted GPS signal is received in the beacon priority area, the GPS positioning information of the vehicle is obtained, and it is determined that the vehicle belongs to a certain beacon priority area.

[0095] At this time, according to the comparison between the GPS positioning information and the positioning information of the end beacon 300 indicating the end of the GPS priority area, it is known that the beacon reader 200 passes through the end beacon 300 but does not scan the end beacon 300, indicating that the end beacon 300 is malfunctioning or damaged.

[0096] As described above, when the vehicle is running in a GPS priority area, the GPS positioning signal is mainly used for vehicle positioning and reporting, and the GPS signal can be used to inspect whether the beacon 300 is malfunctioning.

[0097] In some embodiments of the present application, the controller 100 obtains the code of the start beacon 300 and its installation position information by scanning the start beacon 300 of the beacon priority area through the vehicle-mounted beacon reader 200, indicating that the vehicle has entered the beacon priority area.

[0098] After entering the beacon priority area, the vehicle road segment is reported to the controller 100 according to the beacon scanning result, and according to the information stored in the road network map, the GPS information is not used, and the beacon is simply used for judgment, for example, after scanning the start beacon 300, the controller 100 controls the playing of a certain broadcast or controls the vehicle-mounted PIDS system 500 to report the station through network communication.

[0099] In order for the vehicle to know when to enter the beacon priority area, a start beacon 300 indicating the entry into the beacon priority area is arranged before entering the beacon priority area.

[0100] When the beacon reader 200 scans the start beacon 300 and obtains the code corresponding to the beacon 300, the vehicle considers that it has entered the beacon priority area, at this time, the positioning signal is mainly based on the beacon positioning signal.

[0101] In some embodiments of the present application, in order for the vehicle to know when to exit the beacon priority area, an end beacon 300 indicating the exit from the beacon priority area is arranged before the need to exit the beacon priority area.

[0102] When the beacon reader 200 scans the end beacon 300 and obtains the code corresponding to the end beacon 300, the vehicle considers that it has exited the beacon priority area, and switches the working mode according to the next area type.

[0103] For example, if the next region is a GPS priority region, the GPS priority region corresponding operation mode is switched to, if the next region is a beacon only region without GPS, the beacon only region without GPS corresponding operation mode is switched to (to be described below).

[0104] Generally, the start beacon 300 and the end beacon 300 defining the beacon priority region can both be beacons requiring playing of a point broadcast or an announcement.

[0105] In some embodiments of the present application, when the vehicle is running in a beacon priority region, since the beacon priority region is a GPS untrusted road section, but a stronger GPS signal (i.e., a trusted GPS signal) can be occasionally received, when a trusted GPS signal is received in the beacon priority region, the last scanned beacon 300 is checked by using the GPS positioning signal.

[0106] A set value of the GPS signal strength can be set, and according to the comparison between the real-time GPS signal strength and the set value, whether the current GPS signal is reliable is determined.

[0107] Specifically, the current GPS positioning signal is matched with the last scanned beacon 300, if matched, it indicates that the beacon 300 is not faulty, if not matched, it indicates that the beacon 300 is faulty.

[0108] For example, when exiting a GPS priority region and entering a beacon priority region, when a trusted GPS signal is received in the beacon priority region, the GPS positioning information of the vehicle is obtained, and it is determined that the vehicle belongs to a certain beacon priority region.

[0109] At this time, according to the comparison between the GPS positioning information and the positioning information of the last scanned beacon (i.e., the end beacon 300 indicating the exit of the GPS priority region), it is known that the beacon reader 200 has passed the last beacon 300 but has not scanned the last beacon 300, which indicates that the last beacon 300 is faulty or damaged.

[0110] If a trusted GPS signal has not appeared in the beacon priority region, the last beacon cannot be checked by using the GPS signal until a trusted GPS signal appears.

[0111] For example, after entering adjacent first and second beacon priority regions (in which no trusted GPS signal appears), when entering a third beacon priority region, when a trusted GPS signal is received in the third beacon priority region, the GPS positioning information of the vehicle is obtained, and it is determined that the vehicle belongs to a certain beacon priority region.

[0112] At this time, according to the GPS positioning information respectively compared with the positioning information of the end beacon I indicating the exit of the first beacon priority area and the positioning information of the end beacon II indicating the exit of the second beacon priority area, it is judged that the beacon reader 200 has passed the end beacon I and the end beacon II, but the end beacon I and the end beacon II are not scanned, indicating that the end beacon I and the end beacon II are both malfunctioning or damaged.

[0113] As described above, the vehicle runs in the beacon priority area, adopts the signal positioning signal as the main vehicle positioning station reporting, and can combine the GPS positioning signal to inspect whether the beacon 300 is malfunctioning.

[0114] In some embodiments of the present application, in the only beacon without GPS area, such area is generally a tunnel or a cave, etc.

[0115] In this area, there is generally no GPS signal, therefore, in order to ensure accurate positioning of the vehicle in this area, double beacons are used to position this area.

[0116] In some embodiments of the present application, double beacons 300 are arranged at intervals at the entrance of the only beacon without GPS area.

[0117] For example, two beacons 300 are arranged at intervals of, for example, 50 meters on the track at the entrance of the only beacon without GPS area.

[0118] When the vehicle enters, the beacon reader 200 scans at least one of the double beacons 300, and the vehicle considers itself to have entered the only beacon without GPS area.

[0119] When the vehicle scans one of the double beacons 300, after a period of time, the other one is not scanned, and the malfunction of the corresponding beacon 300 is reported.

[0120] Among them, the period of time as described above can be determined according to the ratio of the set interval and the speed, or the period of time is set as a specified time, and the size of the specified time is selected to be able to run through the distance between the double beacons 300 within the specified time period.

[0121] For example, when the vehicle is about to enter the only beacon without GPS area, the double beacons 300 are recorded as the first beacon and the second beacon respectively according to the vehicle advancing direction.

[0122] After scanning the first beacon, and after a period of time, the second beacon is not scanned, indicating that the second beacon is malfunctioning.

[0123] The first beacon is not scanned, but the second beacon is scanned, and then after a period of time, the first beacon is still not scanned, indicating that the first beacon is malfunctioning.

[0124] In some embodiments of the present application, double beacons 300 are arranged at intervals at the exit of the beacon-only GPS-free area. When the vehicle exits, the beacon reader 200 scans at least one beacon 300 in the double beacons 300, and the vehicle considers itself to have exited the beacon-only GPS-free area.

[0125] When the vehicle scans one beacon 300 in the double beacons 300, and after a period of time, the other beacon 300 is not scanned, a fault is reported for the beacon 300 that is not scanned.

[0126] The period of time can be determined according to the ratio of the set interval and the vehicle speed, or the period of time is set to a specified time, and the size of the specified time is selected to be able to run through the distance between the double beacons 300 within the specified time period.

[0127] For example, when the vehicle exits the beacon-only GPS-free area, the double beacons 300 are recorded as the third beacon and the fourth beacon in the direction of vehicle advancement, respectively.

[0128] When the third beacon is scanned, and after a period of time, the fourth beacon is not scanned, it indicates that the fourth beacon has a fault.

[0129] When the third beacon is not scanned, but the fourth beacon is scanned, and after a period of time, the third beacon is still not scanned, it indicates that the third beacon has a fault.

[0130] As described above, when the vehicle runs in and out of the beacon-only GPS-free area, the beacons 300 can be automatically inspected, and the scenic spot broadcast or station announcement can be automatically played according to the area.

[0131] In some embodiments of the present application, referring to Figure 2 The controller 100 can also control the external lighting control unit 600 to turn on or off the external lighting device 700 based on the vehicle positioning information and the time information.

[0132] The external lighting device 700 can include a searchlight, high / low beam, and vehicle-mounted signal light.

[0133] For example, the searchlight is automatically controlled to turn on according to the sunset time of the location where the vehicle is located or the manually set time, or the searchlight is also automatically controlled to turn on when the vehicle passes through a dark area such as a tunnel or a cave.
