Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Example 1:

[0034] This embodiment provides a train interval control method.

[0035] See Figure 1 The figure shows that the method includes steps S100, S200, S300, S400 and S500.

[0036] Step S100. Obtain the target train's driving information, which includes the target train's operating status data and ground speed limit information data;

[0037] Specifically, the control center obtains the target train's travel information through the Beidou command system. This travel information can reflect the target train's travel status on the current track and the speed limit on that track in a relatively complete manner.

[0038] Step S200. Calculate the safety envelope position information of the target train based on the travel information. The safety envelope position information includes the position of the beginning of the safety envelope and the position of the end of the safety envelope.

[0039] Specifically, the safe envelope position of a train is generally obtained by adding a segment of the train's safe envelope to the estimated position of the train obtained by the high-precision positioning method. It is used for train interval control and ground system updates of track occupancy status, and is divided into safe front position and safe rear position.

[0040] Specifically, step S200 includes:

[0041] Step S210. Obtain basic data, positioning data and communication data of the target train. The basic data includes the body length, weight and wheel friction coefficient of the target train. The positioning data includes the real-time location information of the target train based on the positioning device.

[0042] Step S220. Based on the operating status data and basic data, calculate the target train's overtaking distance, coasting distance, reverse slip protection distance, and emergency braking distance;

[0043] Step S230. Based on the positioning data and operating status data, calculate the positioning error distance of the target train;

[0044] Step S240. Calculate the time delay distance of the target train based on communication data and operating status data;

[0045] Step S250. Based on the target train's body length, overtaking distance, coasting distance, reverse slip protection distance, emergency braking distance, positioning error distance, and time delay distance, calculate the safety envelope information;

[0046] Specifically, the area controller in the control center calculates and configures a safety envelope for each train within its control range. This envelope is based on a comprehensive calculation of the train's position, speed, performance, and expected parameters, thus linking automatic protection mechanisms together until the next train position information is confirmed via a short message received from the Beidou command terminal. Figure 2 As shown, this represents the safety envelope of the train.

[0047] Specifically, the safety envelope information of the target train is mainly used to adjust the driving status of trains located behind and adjacent to the target train. It is necessary to accurately determine which train is behind and adjacent to the target train among all trains running on the current track, so as to ensure the driving safety of the train.

[0048] Step S10. Obtain the travel information and location data of all trains;

[0049] Step S20. Obtain scheduling information, which includes the specific travel routes of all trains within the target time period;

[0050] Step S30. Based on the driving information of all trains, the positioning data of all trains, and the scheduling information, determine the control train that is behind and adjacent to the target train within the target time period;

[0051] Step S40. Obtain the train operation information and number.

[0052] Specifically, the scheduling information of all trains is usually planned in advance. However, in order to avoid special situations that may occur during the journey, it is usually necessary to combine the current travel information and positioning data of all trains to accurately determine the adjacent relationships between all trains, so as to determine the control train corresponding to the target train.

[0053] Step S300. Generate a first target short message based on the safety envelope location information. The first target short message includes safety envelope location information, control train operation information and control train number. The control train operation information includes the target train number and the target direction of operation. The target train and the control train are adjacent trains running on the same rail.

[0054] Specifically, the control center generates corresponding driving instructions for controlling the train based on the safety envelope information of the target train.

[0055] Step S400. Based on the control train number, send the first target short message information to the control train accordingly;

[0056] Specifically, the Beidou command unit sends the first target short message information to the corresponding control train based on the control train number. The Beidou command unit is a device for the control center to command and monitor the Beidou on-board units of various operating trains through the Beidou satellite positioning and navigation system. It can be used for functions such as reporting train running position, issuing remote control commands and information, data query and analysis, and system management.

[0057] Specifically, step S400 includes:

[0058] Step S410. Send the first target short message information to the satellite equipment based on the preset main wave velocity, and confirm receipt of the satellite equipment's reception receipt;

[0059] Specifically, after the RDSS baseband chip of the BeiDou command unit receives the message protocol of the first target short message to be sent, it packages the first target short message information into an encoding based on the space interface protocol standard and sends the encoding to the radio frequency module of the BeiDou command unit. The radio frequency module of the BeiDou command unit modulates the received encoding into a radio frequency signal through binary phase shift keying and sends the radio frequency signal to the power amplifier of the BeiDou command unit. The power amplifier of the BeiDou command unit amplifies the received radio frequency signal and sends the amplified radio frequency signal to the antenna of the BeiDou command unit. The antenna then sends the signal to the satellite equipment. After receiving the reception acknowledgment from the satellite equipment, the first target short message information is deleted from the transmission list. If no acknowledgment information is received, the message is retransmitted after a preset time.

[0060] Step S420. The satellite equipment sends the first target short message information to the satellite control station;

[0061] Step S430. The satellite control station receives the first target short message information, encrypts and decrypts the first target short message information, and sends the encrypted and decrypted first target short message information to the satellite equipment;

[0062] Step S440. The satellite equipment receives and determines the control train number based on the encrypted and decrypted first target short message information, and sends the encrypted and decrypted first target short message information to the control train based on the control train number;

[0063] Specifically, the satellite equipment forwards the received first target short message information to the satellite control station; the satellite control station performs calculation and encryption / decryption processing, and then forwards it to the satellite equipment; the satellite equipment sends the first target short message information to the corresponding control train according to the destination address.

[0064] Step S500. After receiving the first target short message information, the train control system performs driving control based on the safety envelope position information.

[0065] Specifically, the train is equipped with a Beidou onboard unit and a train-mounted control host. The Beidou onboard unit receives the first target short message information sent by satellite equipment. Specifically, the antenna of the Beidou onboard unit receives the radio frequency (RF) signal sent by the satellite equipment and transmits the received RF signal to the low-noise amplifier (LNOA) of the Beidou onboard unit. The LNOA of the Beidou onboard unit amplifies the RF signal with low noise and sends it to the RF module of the Beidou onboard unit. The RF module of the Beidou onboard unit performs frequency conversion processing on the amplified RF signal to obtain an intermediate frequency (IF) signal, and sends the IF signal to the A / D module of the Beidou onboard unit. The intermediate frequency signal is digitally and analogly acquired to obtain the target signal, which is then sent to the RDSS baseband chip of the Beidou vehicle-mounted unit. The RDSS baseband chip of the Beidou vehicle-mounted unit receives and parses the target signal, and determines whether the ID number carried in the parsed target information is the ID number of the Beidou vehicle-mounted unit. When the ID numbers are the same, the target information is extracted and sent to the vehicle-mounted control host. The vehicle-mounted control host can be used to control the train to stop at the moving authorized endpoint, train overspeed protection, reverse slip protection, opening the correct side doors when stopping at stations, automatic train driving, precise stopping in the platform area, and energy saving of train braking and traction based on different speed curves.

[0066] Specifically, step S500 includes:

[0067] Step S510. Compare the target train number with the current actual train number of the controlled train;

[0068] Step S520. When the target train number is the same as the actual train number, compare the target running direction with the current actual running direction of the controlled train;

[0069] Step S530. When the target running direction is the same as the actual running direction, driving control is performed based on the safety envelope position information, and a train control curve is generated accordingly.

[0070] Specifically, after receiving the target information, the train's onboard control host needs to verify whether the train number and direction of travel carried in the target information are the same as those of the current train. If they are the same, the host executes the operation corresponding to the instruction information in the target information. If there is a difference, the host needs to immediately control the train to brake in order to avoid an accident.

[0071] Specifically, after controlling the train's movement, it needs to send its current location information and driving status to the control center so that the control center can carry out control and scheduling for the next cycle.

[0072] Step S600. Receive the second target short message information sent by the control train after performing driving control. The second target short message information includes the control train number, control train type and authorization reply. The authorization reply includes the current operating status of the control train and the current location information of the control train.

[0073] Step S700. Determine the target type corresponding to the control train number from the pre-set train mapping table based on the control train number;

[0074] Step S800. Compare the target type with the controlled train type;

[0075] Step S900. When the target type and the controlled train type are the same, store the current operating status of the controlled train and the current positioning information of the controlled train.

[0076] Specifically, after receiving the second target short message information sent by the train, the control center needs to verify the train number and train type in the short message to ensure that the basic train information is correct before storing it for subsequent safe retrieval.

[0077] Specifically, the control center stores the updated location information and operational status information in the application management server. The application management server can be composed of a database module, an application service module, and a network management module. The database module is mainly used to store BeiDou location information and communication information; the application service module is mainly used for sending and receiving various data, managing various system data, and managing vehicle monitoring data; the network management module is mainly used for network operation management and managing the network communication interface between the system and related systems.
