It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
Fig. 1 is a schematic diagram of an intelligent side-rail train parking system. As shown in fig. 1, an intelligent rail train side intelligent parking system includes: the system comprises a signal transmitting and receiving device 1, a detection target device 2, a signal processing device 3, a central command system 4 and an intelligent rail platform 6.
The signal transmitting and receiving device 1 is arranged at the end part of one side edge of the intelligent rail train 5 and is of an integrated structure of a signal transmitting source and a receiving device. The signal transmitting and receiving device 1 is powered by the power system of the intelligent rail train 5.
The detection target device 2 is arranged at the edge of the intelligent rail platform 6 close to the signal transmitting and receiving device 1, the height of the detection target device 2 is the same as that of the intelligent rail platform 6, and the bottom of the detection target device is level with the pavement layer. The material used for the detection target device 2 has better signal reflection performance, and the signal transmitted by the signal transmitting and receiving device 1 is reflected by the detection target device 2 and then captured by the integrated signal transmitting and receiving device 1 again.
The signal processing device 3 is arranged at the middle lower part in the intelligent rail train 5 and is connected with the signal transmitting and receiving device 1 through a lead, the vehicle-platform distance information can be converted into digital signals through the signal processing device 3, the real-time vehicle-platform distance information is compared with a predefined threshold value, and the digital signals reflecting the vehicle-platform distance deviation can be continuously obtained.
The central control system 4 is arranged right above the signal processing device 3 and is connected with the signal processing device through two leads, the reflected signals are screened and processed by the processing device 3 and then input into the central control system 4, and the signals are identified through the digital information identification module. And then the command is converted into a vehicle steering adjustment command, the direction of the vehicle when entering the station is continuously corrected, and the purpose of rapid and accurate stop is finally realized. The side intelligent identification system applies the principle of laser detection, and the detection signal transmitting frequency can be set based on the train entering speed, or the optimal detection frequency of different entering speeds can be determined through experiments. The running speed can be connected with signal transmission, and corresponding software parameters can be set to realize control. On existing virtual track system, through increasing response element, realize that the vehicle of higher accuracy stops, not only perfect to intelligence rail train itself, still improved the service level of intelligence rail train, this system is less to vehicle itself and road surface transformation moreover, and economic cost is low. Compared with the existing intelligent rail train stopping technology, the system has the advantages of great optimization and promotion in the aspects of precision and station stopping efficiency.
In the range of the system near the train entering the station, the distance measuring device starts to work, and the distance information between the train and the platform can be continuously measured by means of the reflection of the side edge of the train running area and the side edge of the platform structure bottom plate. And according to the vehicle structure size, a vehicle-platform distance threshold value can be defined in advance. The purpose of setting the lower limit of the threshold value is to prevent the train body from being rubbed against the platform due to the processing time of the adjustment instruction and the reaction time of the train when the train is close to the platform in the running process; the purpose of the upper threshold is to control the maximum separation of the vehicle body from the platform.
A parking method of an intelligent rail train side intelligent parking system comprises the following steps:
s1: before the intelligent rail train 5 drives into the vicinity of the platform, the side intelligent parking system is in a closed state, because the detection target device 2 cannot detect the specific signal transmitted by the signal transmitting and receiving device 1 when the distance between the intelligent rail train 5 and the intelligent rail platform 6 is far. And the signal transmitting and receiving device 1 is susceptible to interference of external similar signals.
S2: when the intelligent rail train 5 drives into the vicinity of the platform, the side intelligent parking system is started, and the signal emitting device 1 on the side close to the platform sends out a detection signal. After being reflected by the detection target device 2, the signal is captured by the integrated signal transmitting and receiving device 1.
S3: the reflected signal is screened and processed by the signal processing device 3 and then input into the central control system 4, and when the signal is transmitted into the central control system 4, the signal is identified through the digital information identification module.
S4: the central command system 4 calibrates the signal threshold of the ideal parking position by means of tests and the like. When the signal satisfies the threshold value scope, intelligence rail train and platform interval are comparatively reasonable, and intelligence rail train can keep the direction of travel. When the signal is smaller than the lower limit value, the signal is closer to the platform, and an instruction needs to be sent out to deflect and leave away from the platform; the command parameter may be set according to a difference between the lower limit value and the input value, and converted into a parameter such as a tire deflection angle. When the signal is greater than the upper limit value, the signal is far away from the platform, and an instruction needs to be sent out to deflect towards the platform and approach the platform; determination of the steering command parameter is analogous to setting of a signal less than a lower limit value.
The side intelligent identification system applies the principle of laser detection, and the detection signal transmitting frequency can be set based on the train entering speed, or the optimal detection frequency of different entering speeds can be determined through experiments. The running speed can be connected with signal transmission, and corresponding software parameters can be set to realize control. When the intelligent rail train drives into the vicinity of the platform, the distance between the intelligent rail train and the platform can be determined according to the reflected signal because the intelligent rail train has a certain distance with the platform. The automatic steering and accelerating device avoids excessive adjustment and continuous adjustment in the traditional manual operation, reduces unnecessary steering and accelerating and decelerating operations, and can effectively reduce the labor intensity of a driver and reduce the abrasion of vehicle instruments while ensuring the riding experience level and meeting the parking precision.
It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the scope of the present invention.
