Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, wherein the same reference numerals in the drawings denote the same or similar components.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
With the recent aging of LTE (Long Term Evolution) technology, vehicle-ground communication gradually adopts LTE networks as media to realize transmission. LTE (Long Term Evolution) is a Long Term Evolution of The UMTS (Universal Mobile Telecommunications System) technical standard, which is established by The 3GPP (The3rd Generation Partnership Project) organization. The LTE system introduces key technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input and Multi-Output), which significantly increases spectrum efficiency and data transmission rate, and supports multiple bandwidth allocation, and is the master of the next-generation wireless technology.
Fig. 1 shows an LTE-based train control system according to the present invention. As shown in fig. 1, the train control system 1 includes an on-board device 10, an LTE interface device 20, a master control server 30, and an LTE communication system 40, which are provided on a train. The LTE network 40 comprises LTE base stations 41, which base stations 41 communicate with each other via an LTE core network.
The LTE interface device 20 is capable of communicating with the in-vehicle device 10 via the LTE network 40. For example, the vehicle-mounted device 10 may establish a communication link with its nearest LTE base station 41, and then transfer the train control related information or data collected on the vehicle-mounted device to the LTE interface device 20 also connected to the LTE network via the LTE network 40. Similarly, the LTE interface device 20 may also be connected to an LTE base station and transmit the train control data to the in-vehicle device 10 via the LTE network 40. By adopting the LTE network to transmit the train control data, the rapid and reliable bidirectional train-ground information interaction can be realized, and the development and maintenance cost is saved to a certain extent because a related communication channel specially designed for the rail transit is not needed.
Generally, the operation and maintenance of the LTE network is generally responsible for the LTE network operator. When the LTE network is used as a train-ground communication medium of the train control system, the train control system cannot directly obtain train control data to be monitored or debugged and transmission conditions thereof from the LTE network. Therefore, the inventor of the present invention proposes to add a train control debugging device 80 to the train control system. As shown in fig. 1, the train control debugging device 80 may be connected to the master control server 30 via a wired network to receive the train control data forwarded at the master control server 30 and monitor the operation of the train control system.

Fig. 3 exemplarily shows an external interface schematic diagram of the column control debugging apparatus 80 according to an embodiment of the present invention. A plurality of human-computer interaction interfaces are shown in FIGS. 2 and 3, and the number of human-computer interaction interfaces in practical cases can be customized as required.

In one embodiment, the communication interface 81 is preferably an Ethernet port, as shown in FIG. 3. In practical applications, the communication interface 81 may also be configured as another interface capable of connecting with the master server 30, such as a network interface supporting a specific protocol, or a data transmission interface supporting a specific transmission mode, for example, a WIFI interface. The controller 83 is connected to the communication interface 81. The controller is a conventional microprocessor or microcontroller that can accomplish the configuration and reading of the various ports in the device as with other controllers. The controller 83 is capable of issuing a normal operation indication Norm when the column control data received via the communication interface 81 is normal data. The light port 85 has an indicator light that is connected to the controller 83. The light port 85 is configured to periodically flash an indicator light in response to the normality of operation indication Norm to indicate that the train control system is operating normally. The memory 87 is connected to the controller 83 and is used for storing column control data received via the communication interface 81. The interactive interface 89 is also connected to the controller 83. The interactive interface 89 can be connected to an external human-machine interaction device 90 to output the column control data stored in the memory 87 to the human-machine interaction device 90.
Fig. 3 shows, as an example, a plurality of selectable interaction interfaces 89, each interaction interface 89 enabling interaction between a human operator and a column control commissioning apparatus. One or more of these optional interactive interfaces 89 may coexist. As shown in fig. 3, interactive interface 89-1 is a WIFI interface and may be configured as a WIFI hotspot. Correspondingly, the human-computer interaction device 90 is a device with WIFI access function, such as a mobile handheld device or a notebook computer. The human-computer interaction device 90 may be connected to the WIFI hotspot, and read the train control data stored in the memory 87 of the train control debugging device 80, such as the train control log, the data transmission time, and the like, from the train control debugging device 80 via the WIFI connection. The data can be displayed on a display screen of the human-computer interaction device or form a report file to be presented to an operator.
Alternatively, as shown in fig. 3, the interactive interface 89-2 is a USB interface, which may be connected to a cellular communication module 92, and thus the parallel control debugging means 80 may be accessed via a cellular network. The human-computer interaction device 90 may be any device capable of connecting to a network, such as a notebook computer, a mobile terminal (e.g., a mobile phone, a tablet, etc.), and the like. Once the train control commissioning apparatus 80 is connected to the network via its cellular communication module 92, the train control commissioning apparatus 80 may be configured as a virtual server. The human-computer interaction device 90 can access the train control debugging device 80 as a server through the network, for example, read the train control log, the data transmission time, and the like.
Alternatively, as shown in fig. 3, the USB interface may also be a standard USB interface, which can be connected to a keyboard or a mouse. Preferably, the human-computer interface 89-3 is a video interface, which may be an HDMI interface or a VGA interface, for transmitting audio and/or video signals to a human-computer interaction device (such as a display or a tablet) connected thereto, so as to present column control logs or data transmission information, etc. By combining a keyboard or a mouse connected with the USB interface, an operator can conveniently obtain the train control data information required to be debugged or monitored.

Therefore, the train control debugging device is introduced, the existing train control system based on LTE communication is not changed, and meanwhile, the working state of the train control system is conveniently monitored. The light port on the train control debugging device 80 is originally used for transmitting sound signals and is usually in a normally-on state. The utility model discloses in, this light mouth is configured to the periodic scintillation when train control system normal operation. The light port function can facilitate operators to directly visually observe the running state of the train control system on site without connecting or accessing a train control debugging device.
