The visual operation interface comprises a system operation monitoring interface, an operation diagram interface and a driver's desk interface, and provides convenient interface operation for users. The real departure timer (Departure Time Indicator, DTI) is arranged at each station to provide departure time of the station for train operation, and the time indication of the arrival late condition of the train prompts the train to operate according to the schedule. Normally, after the train enters the platform in whole, the departure time from the schedule is displayed according to the countdown of the stop time given by the system, and the departure time of the train is indicated when the departure time is zero. As shown in fig. 2, the upstream DTI and the downstream DTI of each station are connected to the interface unit equipment (FEP, front end processor) of the train automatic monitoring system (Automatic Train Supervision, ATS) in a single network manner at each equipment central station.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The following describes a departure timer simulation method based on a simulation system according to the present invention with reference to the accompanying drawings.

As shown in fig. 1, the invention provides a departure timer simulation method based on a simulation system, which specifically comprises the following steps:

s1, a simulation system acquires display information sent by a train automatic monitoring system through interface unit equipment, and inputs the display information into a departure timer model;

s2, the simulation system controls the display state of the display interface of the departure timer according to the display strategy in the display information by using the departure timer model, and displays the display data in the display information on the display interface of the departure timer by using the departure timer model.

It should be understood that the departure timer model and the departure timer display interface are built in the simulation system, and only after the departure timer simulation is executed once, the departure timer model and the departure timer display interface are provided in the simulation system, and the departure timer model and the departure timer display interface do not need to be reconstructed again when the departure timer simulation is carried out later except for the case that the departure timer model and the departure timer display interface are required to be modified. Specifically, a virtual simulation model with the same functional logic as a real departure timer, namely a departure timer model, needs to be built in a simulation system, and a simulation equipment interface corresponding to a display screen of the real departure timer, namely a departure timer display interface, is displayed on an equipment running diagram of the simulation system. It should be appreciated that the departure timer model is a logical model, rather than a model that mimics the construction of physical devices. The departure timer model can acquire display information through a simulation system and can control the display state (including but not limited to font color, brightness and the like) and display data (including but not limited to English characters, digital characters and the like) of a departure timer display interface. In an optional embodiment of the present invention, multiple independent threads may exist in the simulation system, for receiving display information sent by different interface unit devices, so that display information sent by multiple interface unit devices may be obtained simultaneously.

For the step S1, the simulation system acquires the display information sent from the train automatic monitoring system through the interface unit device, and inputs the display information into the departure timer model, specifically, the interface unit device can establish data connection with the simulation system, and can send data to the simulation system. It should be understood that the invention is not limited to a particular manner of data connection, as data transmission may be performed using both wired connections (e.g., data transmission lines) and wireless connections (e.g., cellular networks, WLAN, bluetooth, etc.). After the simulation system acquires the display information sent by the interface unit device, the display information is analyzed and corresponds to the device on the overall operation diagram in the simulation system (namely corresponds to the departure timer display interface on the overall operation diagram in the invention), and the display information is input into the departure timer model for processing. In an alternative embodiment of the present invention, a hash table may be used to store the departure timer model, where the key is the ID of the departure timer model within the simulation system and the value is the device object of the departure timer model (i.e., the departure timer simulated by the departure timer model). Information such as a location, a corresponding device ID, and a status is stored in the device object of the departure timer model.

In an alternative embodiment of the invention, the train automatic monitoring system periodically sends display information to the simulation system at preset first time intervals through the interface unit equipment, and the simulation system inputs the display information into the departure timer model for processing after receiving the display information each time. For example, the first time interval may be set to 500ms, that is, the train automatic monitoring system sends display information to the simulation system through the interface unit device every 500ms, so as to continuously control the departure timer model, and provide a basis for the departure timer model to determine whether the data connection between the interface unit device and the departure timer model is normal.

For the step S2, the simulation system controls the display state of the departure timer display interface according to the display policy in the display information by using the departure timer model, and displays the display data in the display information on the departure timer display interface by using the departure timer model, specifically, the departure timer model needs to display the corresponding content on the departure timer display interface according to the display policy and the display data contained in the display information.

In an alternative embodiment of the present invention, as shown in table 1, the display information is a data packet composed of eight bytes, and the number of each of the eight bytes is 0-7, and the display information includes a display policy for controlling the departure timer model, display data for displaying on the departure timer display interface, and information for indicating the connection status of the interface unit device and the automatic train monitoring system. The system comprises a frame head, a frame tail, a frame head and a frame tail, wherein the frame head and the frame tail are respectively used for controlling the display state of a departure timer model, the frame head and the frame tail are respectively used for indicating the connection state of interface unit equipment and an automatic train monitoring system, 1 16-system data are stored in the frame head and the frame tail, and the frame head and the frame tail are respectively used for converting the frame head and the frame tail into 8-system data which can be used for corresponding bytes after being converted into the frame tail; the bytes 3 to 6 are used for storing display data of the departure timer model, wherein hexadecimal numbers are respectively stored in the bytes 3 to 5, each hexadecimal number corresponds to an ascll code and is used for controlling the display data of the departure timer, and the data stored in the byte 6 is XX and represents redundancy.

Byte definition	Function of	Byte length	Remarks
				0	Frame header	1	7D
1-2	Controlling display status	2	Data set, control byte
				3-6	Displaying data	4	Data setting, display data of display area
7	Frame end	1	7E

Each byte contains 8 bits of data numbered 0-7, each of which may store one of 0 or 1. As shown in table 2, of two bytes (i.e., byte No. 1 and byte No. 2) in the display information for controlling the display state of the departure timer model and indicating the connection state of the interface unit device and the train automatic monitoring system, one byte (byte No. 1) includes two bits of data for indicating the brightness and the color of the font of the departure timer model, that is, two bits of data with numbers of 0 and 1, respectively, when the data in bit No. 0 is 0, the brightness of the departure timer is controlled to be 100%, and when the data in bit No. 0 is 1, the brightness of the departure timer is controlled to be 50%; when the data in the bit 1 is 0, the font color of the control departure timer is red, and when the data in the bit 1 is 1, the font color of the control departure timer is green, and the rest bits in the byte 1 are reserved bits. The other byte (byte 2) comprises 4 bits of data for respectively indicating the state of the train in the station, the advanced arrival information, the grouping information and the connection state between the automatic train monitoring system and the interface unit equipment, specifically, the bit 0 is used for controlling the display state of the train in the station, the display is closed when the data in the bit 0 is 0, and the display is opened when the data is 1, and it is understood that the display state of the train in the control station is only kept consistent with other items in the simulation system and is irrelevant to a departure timer; bits 1-3 and bit 7 are reserved bits; the bit 4 is used for storing advanced information, the data in the bit 4 is OFF when 0, namely no advanced information exists, and the data is ON when 1, namely advanced information exists; the number 5 bit is used to store the consist information of the inbound train, in an alternative embodiment of the invention, the data in the number 5 bit represents the 6 consist train when 0 and the 7 consist train when 1, it being understood that the data party in the number 5 bit is valid only when the data in the number 4 bit is 1, i.e., there is the advance inbound information; the number 6 bit is used for storing the connection state of the interface unit equipment and the automatic train monitoring system, when the data in the number 6 bit is 0, the connection establishment of the automatic train monitoring system and the interface unit equipment is indicated, and when the data in the number 6 bit is 1, the connection of the automatic train monitoring system and the interface unit equipment is indicated to be interfered.

Table 2 departure timer control byte table

The departure timer model can control its own display state according to information contained in bytes 1 and 2 in the display message. For example, when the data stored in byte 1 in the display information is 0 and the data stored in byte 2 is 31, the binary corresponding to hexadecimal number 0 is 00000000, i.e., the data stored in bits 0-7 of byte 1 are all 0; the binary digits corresponding to the hexadecimal digits 31 are 00110001,2 bytes, when the binary digits correspond to 8 bits in the data, the data are required to be in reverse order, namely, the data stored in the 0-7 bits in the 2 bytes are respectively 1, 0, 1, 0 and 0, and at the moment, the corresponding meaning of the display information is 100% brightness, red font display, in-station train state display starting, the train is about to get in into 7 groups, and the connection between the train automatic monitoring system and interface unit equipment is established.

The departure timer model can control its own display data according to information contained in bytes 3-5 in the display message. For example, when hexadecimal data stored in bytes 3-5 are respectively 30, 38 and 35, corresponding ascll codes are respectively 0, 8 and 5, and the departure timer model is displayed 085 in the departure timer display interface.

In a preferred embodiment of the present invention, the method for simulating a departure timer based on the simulation system further includes step S3, where the simulation system obtains diagnostic information generated by the departure timer model, and sends the diagnostic information to the interface unit device. It should be understood that there is no specific timing relationship between the step S3 and the steps S1 and S2.

Specifically, the departure timer model can generate diagnostic information, and the simulation system can acquire the diagnostic information and send the diagnostic information to the interface unit device, so that the train automatic monitoring system acquires the diagnostic information through the interface unit device, and determines a fault state of the departure timer based on the diagnostic information. In an alternative embodiment of the invention, the departure timer model can periodically send diagnostic information to the interface unit device at preset second time intervals, e.g. the second time intervals may be set to 30s, i.e. the departure timer model can periodically generate diagnostic information at intervals of 30s and send it to the interface unit device via the simulation system.

The diagnostic information includes information indicating a fault condition of the departure timer model. In an alternative embodiment of the invention, as shown in table 3, the diagnostic information is a data message containing 6 bytes numbered 0-5, wherein the two bytes numbered 1 and 5 are the frame header and frame trailer, respectively, the byte numbered 1 is used to store the module number (DTI as an integrated device reporting its status without further splitting into separate modules, so the module number of DTI is always 0), the two bytes numbered 2-3 are used to store the line number, and the byte numbered 4 is used to represent the internal failure status of the departure timer model.

Bytes	Function of	Byte length	Remarks
				0	Frame header	1	7D
1	Module number	1	0＝DTI
				2-3	Line number	2	Unused and not used
4	Internal failure	1	0=normal, 1=failure
				5	Frame end	1	7E

After the train automatic monitoring system obtains the diagnosis information through the interface unit equipment, whether the departure timer model has internal faults can be judged according to the data stored in the byte with the number of 4 in the diagnosis information.

In an optional embodiment of the present invention, before the step S3, the simulation system acquires the diagnostic information generated by the departure timer model and sends the diagnostic information to the interface unit device, the method further includes:

it is checked whether the communication connection between the interface unit device and the departure timer model is stable. By checking the steady state of the communication connection, the stability of the communication connection between the checking interface unit device and the departure timer model can be evaluated.

Specifically, checking whether the communication connection between the interface unit device and the departure timer model is stable or not includes: and in the third time interval above the current time, under the condition that the departure timer model receives at least one piece of display information, judging that the communication connection between the interface unit equipment and the departure timer model is stable. It should be appreciated that the third time interval should be equal to or longer than the first time interval described above, e.g. when the first time interval is 500ms, the third time interval may be set to 1000ms.

In an alternative embodiment of the present invention, in the step S1, after acquiring the display information sent by the automatic train monitoring system through the interface unit device, before inputting the display information into the departure timer model, the method further includes: and checking whether the communication connection between the automatic train monitoring system and the interface unit equipment is stable or not so as to evaluate the stability of the communication connection between the automatic train monitoring system and the interface unit equipment.

Checking whether the communication connection between the train automatic monitoring system and the interface unit equipment is stable or not, specifically comprising the following steps: and under the condition that the information for indicating the connection state of the interface unit device and the automatic train monitoring system accords with the preset normal connection condition (namely, when the data of the 6 th bit of the 2 nd byte in the table 2 is 0), judging that the connection between the automatic train monitoring system and the interface unit device is stable.

The departure timer simulation method based on the simulation system provided by the invention is specifically described in the following operation process of the departure timer model corresponding to the actual operation process of a plurality of simulated trains:

assuming A, B two stations, each of which has one DTI (corresponding to the departure timer model and departure timer display interface in the invention), both DTIs can perform data transmission with FEP, and the train runs from station a to station B.
