Description

Technical Field

[0001] The present application relates to the field of Internet technology, and more specifically, to a train blocking system and method. Background Art

[0002] With the progress of science and technology, my country's railways have made great progress, and the requirements for train blocking methods are getting higher and higher. At present, 60% of my country's railway lines officially in operation adopt 64D semi-automatic blocking methods. Semi-automatic blocking must be carried out by the duty officers of the two stations according to the prescribed procedures to organize the section running. The station duty officer confirms the arrival of the entire train and handles the arrival recovery before the section can release the blocking state. This method of relying on the duty officers of the departure station and the receiving station to jointly handle the blocking in a "request-consent" manner has high labor costs and requires the setting of 13 relays and related indication circuits, while the relays are expensive and the relay circuits are relatively complex. In short, the existing 64D semi-automatic blocking method has high costs and low economic benefits. Summary of the invention

[0034] Preferably, the terminal is also used to determine whether a signal indicating that the train has arrived at the end of the section has been fed back to the terminal in the previous adjacent station between the time when the last request to enter the train was received from the terminal in the previous adjacent station before the current time and the current time, when receiving a request to enter the train sent by the terminal in the previous adjacent station of the station. If so, a signal allowing the train to enter is sent to the terminal in the previous adjacent station of the station.

[0037] The process of the terminal sending a train entry request signal to a terminal in a station adjacent to the station where the terminal is located comprises:

[0038] The terminal uses the RSSP-1 protocol to send a train entry request signal to a terminal in a station adjacent to the station where the terminal is located.

[0039] A train blocking method is applied to any terminal in a train blocking system, wherein the train blocking system comprises: a terminal and an indication device arranged in a station between two adjacent track sections, a first sensor arranged at a starting position of each track section and a second sensor arranged at an end position, wherein the terminal in each station is respectively connected to the indication device in the station, the second sensor on the track section in the station's entry direction, the first sensor on the track section in the station's exit direction, and the terminals in two adjacent stations of the station;

Therefore, at this time, it can be judged whether there is a train in the track section that the train wants to enter by judging whether a signal of the train arrival end is received from the terminal in the next adjacent station between the time when the last request for entry signal was sent to the terminal in the next adjacent station of the station before the current time and the current time. If so, it means that there are no other trains in the track section or the train has traveled to the end of the track section.

[0062] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] See also Figure 1 , Figure 1 A schematic diagram of the structure of a train block system provided in an embodiment of the present application.

[0064] A train blocking system provided in an embodiment of the present application may include:

[0065] Terminals and indicator equipment installed in stations between two adjacent track sections.

[0066] A first sensor is provided at the beginning of each track section and a second sensor is provided at the end of each track section.

[0067] Among them, the terminal is a device with data processing capabilities, which can be a host, server, etc. The indicating device is a vehicle traffic guidance device, which can be a signal light, a lane gate, etc. The first sensor and the second sensor are both sensing devices that can detect trains, which can be electromagnetic sensors, infrared sensors, etc.

[0068] The terminal in each station is respectively connected to the indicating device in the station, the second sensor on the track section in the direction of entering the station, the first sensor on the track section in the direction of leaving the station, and the terminals in the two adjacent stations of the station.

[0069] Specifically, the terminal in each station needs to be connected to the indicating device in the station so that the train can be instructed to pass by controlling the indicating device to which it is connected in different scenarios. Each terminal also needs to be connected to the second sensor on the track section in the direction of the station and the first sensor on the track section in the direction of the station, and collect information from the two connected sensors in real time. Since both connected sensors can detect trains, the position of the train can be determined based on the collected sensor information, and different responses can be made according to the different positions of the train. In addition, each terminal needs to be connected to the terminals in the two stations adjacent to the station so as to communicate in real time with the terminals in the two stations adjacent to the station and jointly realize the blocking of the train.

[0070] The terminal is used to control the connected indicating device to enter the first indicating state when it is determined that the connected second sensor detects the passage of a train, and to send a signal indicating that the train has arrived at the end of the section to the terminal in the previous adjacent station of the station where the terminal is located, and to determine whether a signal indicating that the train has arrived at the end of the section is received as feedback from the terminal in the next adjacent station between the time when the last signal requesting entry was sent to the terminal in the next adjacent station of the station before the current moment and the current moment; if so, to send a signal requesting entry to the terminal in the next adjacent station of the station where the terminal is located, and to control the connected indicating device to enter the second indicating state when a signal allowing entry is received as feedback; if not, to control the connected indicating device to maintain the first indicating state.

[0071] It is understandable that the above-mentioned control connection indicating device enters the first indicating state, and sends a signal indicating that the train has arrived at the end of the section to the terminal in the previous adjacent station of the station where the station is located, and determines whether a signal indicating that the train has arrived at the end of the section is received as feedback from the terminal in the next adjacent station between the time when the last signal requesting entry was sent to the terminal in the next adjacent station of the station before the current moment and the current moment. The execution order of the three can be adjusted. For example, the three processes can be executed in parallel without any order of priority or in any order of priority.

[0072] The first indication state is a state indicating that trains are prohibited from passing, and the second indication state is a state indicating that trains are allowed to pass.

[0073] Specifically, since the terminal in each station is connected to the second sensor on the track section in the direction of entry to the station, when the terminal in a station determines that the connected second sensor detects a train passing, it can be determined that the train has reached the end position of the track section between the station and the adjacent station before the station, and is about to enter the track section between the station and the adjacent station after the station. Therefore, at this time, the connected indicating device should be controlled to enter the first indicating state to indicate that the train is prohibited from passing, so as to prevent the train from colliding with other existing trains after entering the track section where there are other trains running.

[0074] In addition, a signal indicating that the train has arrived at the end of the section is sent to the terminal in the adjacent station before the current station, so that the terminal in the adjacent station before the current station can determine that the train has arrived at the end of the section. When it is determined again that the connected second sensor detects the passing of the train, it can be determined that there are no other trains running in the track section that the train is about to enter.

[0075] Also, determine whether there are other trains running on the track section that the train is about to enter. Because every time the train reaches the end of the track section, the receiving terminal will send a signal that the train has arrived at the end to the terminal in the station immediately before the station where it is located, indicating that the next train can be released. Therefore, it is possible to determine whether there are other trains running on the track section that the train is about to enter by determining whether a signal that the train has arrived at the end of the section is received from the terminal in the station immediately after the station between the time when the train last sent a request to enter signal to the terminal in the station immediately after the station before the current time and the current time.

[0076] If a signal is received from a terminal in an adjacent station behind the station that a train has arrived at the end of the section, it means that there is no train in the track section that the train is about to enter or the train has already traveled to the very end of the track section. At this time, there will be no collision between the two trains when the train enters the track section. At this time, a signal requesting entry can be sent to the terminal in the adjacent station behind the station, and when a feedback signal allowing entry is received, the connected indicating device is controlled to enter the second indicating state, that is, the train is released. If no signal is received, it means that the terminal in the adjacent station behind the station has not received the train and the train is still traveling on the track section. At this time, in order to avoid a collision between the two trains, the connected indicating device should be controlled to maintain the first indicating state, that is, the train is prohibited from entering, until a signal is received from the terminal in the adjacent station that a train has arrived at the end of the section, and then a request for entry is made to the terminal in the adjacent station.

[0077] The train blocking system provided by the embodiment of the present application controls the connected indicating device to enter a state indicating that the train is prohibited from passing when the connected second sensor determines that the train has passed. The train is prohibited from passing and a signal that the train has arrived at the end of the section is sent to the terminal in the previous adjacent station of the station. Therefore, at this time, it can be determined whether there is a train in the track section that the train wants to enter by judging whether the signal of the train arrival end is fed back from the terminal in the next adjacent station between the time when the last signal requesting entry was sent to the terminal in the next adjacent station of the station before the current time and the current time. If so, it means that there is no other train in the track section or the train has reached the end of the track section. At this time, When a train enters the track section, there will be no collision between the two trains. Therefore, a request to enter signal is sent to the terminal in the next adjacent station of the station where the train is located. When the feedback signal allowing the train to enter is received, the connected indicating device is controlled to enter the state indicating that the train is allowed to pass. If not, it means that there is a train in the track section, and the connected indicating device should be controlled to maintain the state indicating that the train is prohibited from passing. Only the terminal and indicating device in the station between the two adjacent track sections and the first sensor at the starting position and the second sensor at the end position of each track section are required to realize the blocking of the train without human intervention, and the expensive relays are eliminated, thereby reducing the cost of implementing the blocking. The entire train blocking system is simple, low-cost, and improves economic benefits.

[0078] In some embodiments of the present application, in order to ensure the correctness of the communication signal, the terminals in each two adjacent stations can communicate through the RSSP-1 protocol. Based on this, the process of the above-mentioned terminal sending a signal that the train has arrived at the end of the section to the terminal in the previous adjacent station of the station is introduced. The process may include:

[0079] The terminal uses the RSSP-1 protocol to send a signal that the train has arrived at the end of the section to the terminal in the previous adjacent station of the station where the terminal is located. The RSSP-1 protocol is a railway signal safety communication protocol.

[0080] The process of sending a train entry request signal from the upper terminal to the terminal in the next adjacent station of the station where the upper terminal is located is introduced. The process may include:

[0081] The terminal uses the RSSP-1 protocol to send a train entry request signal to a terminal in a station adjacent to the station where the terminal is located.

[0082] Optionally, the terminals in every two adjacent stations may also communicate with each other through other railway signal safety communication protocols, such as the RSSP-2 protocol.

[0083] In the embodiment of the present application, since the communication between terminals uses the railway signal safety communication protocol RSSP-1 protocol, the correctness of the communication signal is guaranteed.

[0084] The embodiment of the present application finds that after the above-mentioned terminal receives the signal of allowing the train to enter fed back by the terminal in the adjacent station behind the station where the terminal is located, it will control the connected indicating device to enter the second indicating state, that is, to indicate that the train is allowed to pass. In order to enable the terminal in the adjacent station behind the station where the train enters to know the position of the train in real time after the train enters, the terminal can also be used to send a signal of the train arriving at the starting point of the section to the terminal in the adjacent station behind the station where the terminal is located when it is determined that the first connected sensor detects the passing of the train, and receive the feedback signal of ready to receive the train from it, and send a train departure signal to the terminal in the adjacent station behind the station where the terminal is located when it is determined that the first connected sensor detects the departure of the train.

[0085] Specifically, when the terminal determines that the first sensor connected to it detects the passage of a train, it means that the train has arrived at the starting point of the track section between the next adjacent station of the station where the terminal is located, and a signal indicating that the train has arrived at the starting point of the section can be sent to the terminal in the next adjacent station of the station where the terminal is located. At this time, if the terminal in the next adjacent station of the station where the terminal is located receives the signal indicating that the train has arrived at the starting point of the section, it can be known that the train has reached the starting point of the track section and is approaching itself, and at this time, a signal indicating that it is ready to receive the train is fed back. When it is determined that the first sensor connected to it detects that the train has left, it means that the train has completely traveled on the track section, and a train departure signal can be sent to the terminal in the next adjacent station of the station where the terminal is located. After receiving the train departure signal, the terminal can know that the train has completely departed.

[0086] Among them, the signal of train arrival at the starting point of the section, the signal of ready to receive the train, the signal of train departure, etc. transmitted between the above-mentioned terminal and the terminal in the next adjacent station of the station can all be transmitted using the RSSP-1 protocol.

[0087] In the embodiment of the present application, since each terminal will send a signal that the train has arrived at the starting point of the section to the terminal in the next adjacent station of the station when it determines that the connected first sensor has detected the passage of a train, and send a train departure signal to the terminal in the next adjacent station of the station when it determines that the connected first sensor has detected the departure of a train, the terminal in the next adjacent station of the station can know the position of the train in real time, and will feedback a signal of preparing to receive the train when receiving the signal that the train has arrived at the starting point of the section. If the terminal does not receive the feedback signal of preparing to receive the train, it may indicate that the terminal in the next adjacent station of the station may have a malfunction and may be unable to receive the train. When it is determined again that the connected second sensor has detected the passage of a train, the connected indication device can be controlled to maintain the first indication state, that is, to indicate that the train is prohibited from passing until the terminal in the next adjacent station of the station returns to normal.

[0088] The embodiment of the present application finds that when the above-mentioned terminal receives a request for entry signal sent by a terminal in an adjacent station before the station where the terminal is located, although the terminal in the adjacent station before the station where the terminal is located has determined that there are no other trains running on the track section between the two, in order to further ensure the safety of driving, the terminal may determine again whether there are other trains running on the track section, and only feedback a signal allowing entry if it is determined that there are no other trains running.

[0089] Based on this, the above-mentioned terminal is also used to determine whether a signal indicating that the train has arrived at the end of the section has been fed back to the terminal in the previous adjacent station of the station between the time when the last request to enter signal sent by the terminal in the previous adjacent station of the station was received before the current time and the current time when the above-mentioned terminal is also used to determine whether a signal indicating that the train has arrived at the end of the section has been fed back to the terminal in the previous adjacent station of the station between the time when the last request to enter signal sent by the terminal in the previous adjacent station of the station before the current time and the current time. Since the signal indicating that the train has arrived at the end of the section will be fed back to the terminal in the previous adjacent station of the station only when the connected second sensor detects that a train has passed, if the signal has been fed back, it means that there is no train in the track section between the previous adjacent station or the train has reached the end position. At this time, even if the train enters the track section, it will not cause a vehicle collision. Therefore, a signal indicating that the train is allowed to enter can be sent to the terminal in the previous adjacent station of the station. Otherwise, a signal indicating that the train is allowed to enter will not be sent to the terminal in the previous adjacent station of the station until it is determined that the signal indicating that the train has arrived at the end of the section has been fed back to the terminal in the previous adjacent station of the station.

[0090] In the embodiment of the present application, when a train wants to enter a certain track section, the train can only enter the track section when the terminals in the stations at both ends of the track section determine that there are no other trains running on the track section, thereby further ensuring the safety of driving.

[0091] In some embodiments of the present application, the first sensor disposed at the starting position of each track section and the second sensor disposed at the end position may both be electromagnetic sensors.

[0092] Based on this, the method for the above-mentioned terminal to determine that the connected second sensor detects the passing of a train can be: real-time collection of the voltage of the connected second sensor, and determination whether the voltage of the connected second sensor begins to change; if so, determination that the connected second sensor detects the passing of a train.

[0093] Similarly, the method for the above-mentioned terminal to determine that the connected first sensor detects the passing of a train can be: real-time collection of the voltage of the connected first sensor, and determination whether the voltage of the connected first sensor begins to change; if so, determination that the connected first sensor detects the passing of a train.

[0094] The method for the above-mentioned terminal to determine that the connected first sensor detects the departure of the train can be: judging whether the number of voltage changes of the connected first sensor is equal to the number of voltage changes of the connected second sensor, and if so, determining that the connected first sensor detects the departure of the train.

[0095] In the embodiment of the present application, since electromagnetic sensors are set at the starting position and the end position of each track section to detect whether a train has passed or left, and the electromagnetic sensors rely on electromagnetic characteristics to work and are not affected by the roadbed environment, changes in the roadbed environment will not affect the operation of the electromagnetic sensors. When the roadbed environment changes, the electromagnetic sensors can still work normally, thereby improving the practicality of train blocking.

[0096] In the embodiment of the present application, the structure of the terminal in the train block system in the above embodiment is described in detail:

[0097] Figure 2 A schematic diagram of the structure of a terminal disclosed in an embodiment of the present application is shown in FIG. Figure 2 As shown, it may include:

[0098] The control module 100 is used to control the connected indicating device to enter the first indicating state when it is determined that the connected second sensor detects the passage of a train, and to send a signal indicating that the train has arrived at the end of the section to the safety logic module 110, and to determine whether a signal indicating that the train has arrived at the end of the section is received as feedback from the terminal in the next adjacent station to the station before the current moment. If so, a signal indicating that the train has entered is sent to the safety logic module 110, and when a signal indicating that the train is allowed to enter is received as feedback, the connected indicating device is controlled to enter the second indicating state; if not, the connected indicating device is controlled to maintain the first indicating state.

[0099] The safety logic module 110 is used to forward the signal sent by the control module 100 indicating that the train has reached the end of the section to the signal transmission module 120, forward the signal of requesting the train to enter sent by the control module 100 to the signal transmission module 120, and forward the signal of allowing the train to enter sent by the signal transmission module 120 to the control module 100.

[0100] The signal transmission module 120 is used to forward the signal sent by the safety logic module 110 indicating that the train has reached the end of the section to the terminal in the previous adjacent station of the station, forward the request to enter the train signal sent by the 110 safety logic module to the terminal in the next adjacent station of the station, and forward the permission to enter the train signal fed back by the terminal in the next adjacent station of the station to the safety logic module 110.

[0101] In some embodiments of the present application, the process of the control module 100 sending a signal that the train has arrived at the end of the section to the safety logic module 110 is introduced, and the process may include:

[0102] The control module 100 sequentially sends each bit signal of the binary type signal indicating that the train has arrived at the end of the section to the safety logic module 110 .

[0103] Specifically, developers can use a preset signal to represent the signal of the train arriving at the section. For example, 5 represents the signal of the train arriving at the end of the section. The basis of computer technology operation is binary, so the signal of the train arriving at the end of the section transmitted by the control module 100 to the safety logic module 110 can be a binary signal. For example, if 5 represents the signal of the train arriving at the end of the section, then the signal transmitted by the control module 100 to the safety logic module 110 is 101. If the control module 100 directly transmits the binary signal of the train arriving at the end of the section to the safety logic module 110, and the safety logic module 110 directly transmits the binary signal of the train arriving at the end of the section to the signal transmission module 120, the signal is easily interfered during the transmission process. Therefore, the control module 100 can send each bit signal of the binary signal of the train arriving at the end of the section to the safety logic module 110 in sequence, so that the safety logic module 110 inputs each bit signal received into the preset gate circuit, and transmits each bit output signal independently output by the gate circuit to the signal transmission module 120.

[0104] Based on this, the above-mentioned safety logic module 110 will sequentially receive each bit of the signal sent by the control module 100 indicating that the train has arrived at the end of the section, and will also be used to sequentially input each bit of the received signal as an input signal into a preset gate circuit, and sequentially obtain each bit of the output signal output by the gate circuit as a signal indicating that the train has arrived at the end of the section after editing, and forward the above-mentioned signal indicating that the train has arrived at the end of the section after editing to the signal transmission module 120.

[0105] Among them, the structural diagram of the gate circuit is as follows Figure 3 As shown, the gate circuit inputs the input signal and 0 into the XOR gate to output the first result, inputs the input signal and the first result into the AND gate to output the second result, inputs 0 and the first result into the AND gate to output the third result, inputs the second result and the third result into the XOR gate to output the output signal. It can be seen that when the signal is input into the gate circuit as the input signal of the gate circuit, the output signal obtained must be consistent with the input signal. For example, when 1 is input into the gate circuit as the input signal, the gate circuit will input 1 and 0 into the XOR gate to output 1, input 1 and 1 into the AND gate to output 1, input 0 and 1 into the AND gate to output 0, input 1 and 0 into the XOR gate to output the output signal 1. Similarly, if 0 is input into the gate circuit as the input signal, the output signal output by the gate circuit is also 0.

[0106] Specifically, after the safety logic module 110 receives each bit of the signal indicating that the train has arrived at the terminal position sent sequentially by the control module 100, it does not directly send each bit of the received signal to the signal transmission module 120, but instead uses each bit of the received signal as the input signal of the above-mentioned gate circuit in sequence, and inputs each bit of the output signal of the gate circuit, i.e., the signal indicating that the train has arrived at the end of the section after the above-mentioned editing, to the signal transmission module 120. By transmitting each individual signal of the signal indicating that the train has arrived at the terminal through the gate circuit, it is possible to reduce external interference with the signal while ensuring the correctness of the transmitted signal, and each bit of the signal is output independently, so that safety is guaranteed.

[0107] Based on this, the signal transmission module 120 will sequentially receive the signals of each edited train arrival at the end of the section sent by the safety logic module 110, and after receiving them, it will merge each signal in the order of reception and send the signal of the train arrival at the end of the section to the terminal in the previous adjacent station of the current station.

[0108] In the embodiment of the present application, after the safety logic module 110 receives each bit of the signal of the train arriving at the terminal position sent sequentially by the control module 100, each bit of the received signal is sequentially used as the input signal of the above-mentioned gate circuit, and is sequentially input into the gate circuit, and each bit of the output signal of the gate circuit, that is, the signal of the train arriving at the end of the section after the above-mentioned editing, is forwarded to the signal transmission module 120, and each individual signal of the signal of the train arriving at the terminal position is transmitted through the gate circuit, which not only ensures the correctness of the signal of the train arriving at the terminal position, but also reduces the interference of the outside world in the signal transmission process of the train arriving at the terminal position, so that each bit of the signal of the train arriving at the terminal position is output independently, and the safety is guaranteed.

[0109] Based on the above embodiments, in some embodiments of the present application, the process of the control module 100 sending a vehicle entry request signal to the safety logic module 110 is introduced, and the process may include:

[0110] The control module 100 sends each bit of the binary vehicle entry request signal to the safety logic module 110 in sequence.

[0111] Based on this, the above-mentioned safety logic module 110 will sequentially receive each bit of the vehicle entry request signal sent by the control module 100, and is also used to input each bit of the received vehicle entry request signal as an input signal into the gate circuit, and sequentially obtain each bit of the output signal output by the gate circuit as the edited vehicle entry request signal.

[0112] The process in which the safety logic module 110 forwards the vehicle entry request signal sent by the control module 100 to the signal transmission module 120 may include:

[0113] The safety logic module 110 forwards the edited vehicle entry request signal to the signal transmission module 120 .

[0114] Based on this, the signal transmission module 120 will sequentially receive each edited request-to-enter signal sent by the safety logic module 110, and after receiving each signal, will send the request-to-enter signal merged in the order of reception to the terminal in the next adjacent station of the station.

[0115] In the embodiment of the present application, after the safety logic module 110 receives each bit of the vehicle entry request signal sent sequentially by the control module 100, each bit of the received signal is sequentially used as the input signal of the above-mentioned gate circuit, and is sequentially input into the gate circuit, and each bit of the output signal of the gate circuit, i.e., the edited vehicle entry request signal, is forwarded to the signal transmission module 120. Each individual signal of the vehicle entry request signal is transmitted through the gate circuit, which not only ensures the correctness of the vehicle entry request signal, but also reduces the interference of the outside world in the transmission process of the vehicle entry request signal, so that each bit of the vehicle entry request signal is output independently, and the safety is guaranteed.

[0116] On the basis of the above embodiments, in some embodiments of the present application, the process of the signal transmission module 120 forwarding the entry permission signal fed back by the terminal in the next adjacent station of the station to the safety logic module 110 is introduced, and the process may include:

[0117] The signal transmission module 120 sequentially forwards each bit of the binary type vehicle entry permission signal fed back by the terminal in the next adjacent station of the station to the above-mentioned safety logic module 110 .

[0118] Based on this, the above-mentioned safety logic module 110 will sequentially receive each bit of the vehicle entry permission signal sent by the signal transmission module, and is also used to receive each bit of the above-mentioned vehicle entry permission signal as an input signal input into the above-mentioned gate circuit, and sequentially obtain each bit of the output signal output by the gate circuit as the edited vehicle entry permission signal.

[0119] The process of the safety logic module 110 forwarding the vehicle entry permission signal sent by the signal transmission module 120 to the control module 100 may include:

[0120] The safety logic module 110 forwards the edited vehicle entry permission signal to the control module 100 .

[0121] In the embodiment of the present application, after the safety logic module 110 receives each bit of the vehicle entry permission signal sent sequentially by the signal transmission module 120, each bit of the received signal is sequentially used as the input signal of the gate circuit, and sequentially input into the gate circuit, and each bit of the output signal of the gate circuit, i.e., the edited vehicle entry permission signal, is forwarded to the control module 100, and each individual signal of the vehicle entry permission signal is transmitted through the gate circuit, which not only ensures the correctness of the vehicle entry permission signal, but also reduces the interference of the outside world in the transmission process of the vehicle entry permission signal, so that each bit of the vehicle entry permission signal is output independently, and the safety is guaranteed.

[0122] See also Figure 4 , Figure 4 An optional flow chart of a train blocking method provided in an embodiment of the present application. A train blocking method provided in an embodiment of the present application is applied to any terminal in a train blocking system, wherein the train blocking system may include: a terminal and an indicating device arranged in a station between two adjacent track sections, a first sensor arranged at the starting position of each track section and a second sensor arranged at the end position, and the terminal in each station is respectively connected to the indicating device in the station, the second sensor on the track section in the direction of entering the station, the first sensor on the track section in the direction of leaving the station, and the terminals in two adjacent stations of the station.

[0123] The above train blocking method may include:

[0124] Step S200: Determine whether the connected second sensor detects the passage of a train.

[0125] Specifically, as described in the aforementioned embodiment, the connected second sensor is a sensing device that can detect a train, so it is possible to determine whether the connected second sensor has detected the passage of a train by collecting information from the second sensor. Optionally, the second sensor may be an electromagnetic sensor, and the collected sensor information is voltage. At this time, if it is determined that the voltage of the connected second sensor begins to change, then it can be determined that the connected second sensor has detected the passage of a train.

[0126] Step S210: Control the connected indicating device to enter a first indicating state.

[0127] Specifically, when it is determined that the connected second sensor detects the passing of a train, that is, it is determined that the train is about to enter the track section between the adjacent station behind the current station, in order to avoid a collision between the train and other trains in the track section, the connected indicating device should first be controlled to enter the first indicating state, wherein the first indicating state is a state indicating that the train is prohibited from passing.

[0128] Step S220: Send a signal indicating that the train has arrived at the end of the section to the terminal in the previous adjacent station of the current station.

[0129] Specifically, since the connected second sensor is set at the end position of the track section between the previous adjacent station of the station, when it is determined that the connected second sensor detects the passing of a train, it can be determined that the train has reached the end position of the track section, so a signal indicating that the train has arrived at the end of the section is sent to the terminal in the previous adjacent station of the station, so that the terminal in the previous adjacent station knows that the train has entered the end position and can release the next train.

[0130] Step S230, determine whether a signal indicating that the train has arrived at the end of the section is received from the terminal in the next adjacent station between the time when the train entry request signal was last sent to the terminal in the next adjacent station before the current time and the current time.

[0131] Specifically, since when it is determined that the connected second sensor detects the passage of a train, a signal indicating that the train has arrived at the end of the section will be sent to the terminal in the previous adjacent station of the station. Therefore, when the terminal in the next adjacent station of the station determines that the connected second sensor detects the passage of a train, it will also receive a signal indicating that the train has arrived at the end of the section sent by the terminal, indicating that the train has reached the end of the section and the next train can be released. Therefore, it is possible to determine whether there are other trains running on the track section between the next adjacent station and the next adjacent station by judging whether a signal indicating that the train has arrived at the end of the section is received from the terminal in the next adjacent station between the time when the last signal requesting entry was sent to the terminal in the next adjacent station of the station before the current time and the current time.

[0132] If yes, execute the following steps S240-S260, if no, execute the following step S270.

[0133] Step S240: Send a train entry request signal to a terminal in a station adjacent to the station where the train is located.

[0134] Step S250: Receive a signal allowing train entry fed back by a terminal in a station adjacent to the station where the train is located.

[0135] Step S260: Control the connected indicating device to enter the second indicating state.

[0136] Specifically, if between the time when a request to enter the train signal was most recently sent to a terminal in the next adjacent station of the station before the current time and the current time, a signal indicating that a train has arrived at the end of the section is received as feedback from the terminal in the next adjacent station of the station, then it means that there are no other trains running on the track section between the next adjacent station of the station. At this time, a request to enter the train signal can be sent to the terminal in the next adjacent station to request the train to enter the train. After receiving the request to enter the train signal, the terminal in the next adjacent station will feedback a signal allowing the train to enter. Therefore, after receiving the feedback signal allowing the train to enter, the connected indicating device can be controlled to enter the second indicating state, wherein the second indicating state is a state indicating that the train is allowed to pass. At this time, the train is released. Optionally, after the terminal in the next adjacent station receives the request to enter the train signal, it can again determine that there is no train running on the track section and then feedback a signal allowing the train to enter.

[0137] Step S270: Control the connected indicating device to maintain the first indicating state.

[0138] Specifically, if no signal indicating that a train has arrived at the end of the section is received from the terminal in the next adjacent station after the station between the time when the last request for entry signal was sent to the terminal in the next adjacent station after the station before the current moment and the current moment, it means that the terminal in the next adjacent station after the station has not received the train, and there are still trains running on the track section between the next adjacent station and the station. In order to avoid vehicle collision, the connected indicating device should be controlled to maintain the first indicating state, and trains are prohibited from passing.

[0139] It is understandable that the above execution order of steps S210-230 does not constitute a limitation to the present invention, and the execution order of steps S210-230 can be adjusted. For example, the three steps can be executed in parallel without any particular order or in any order.

[0140] The train blocking method provided in the embodiment of the present application only requires terminals and indicating devices to be set up in the station between two adjacent track sections, as well as a first sensor to be set at the starting position of each track section and a second sensor to be set at the end position, to achieve train blocking without human intervention, and eliminates expensive relays, thereby reducing the cost of implementing blocking. The entire train blocking system is simple, low-cost, and improves economic benefits.

[0141] In the embodiment of the present application, it is found that in order to enable the terminal in the adjacent station behind the station to know the position of the train in real time after the terminal indicates that the train can enter a certain track section, the above train blocking method may also include:

[0142] When it is determined that the connected first sensor detects the passage of a train, a signal indicating that the train has arrived at the starting point of the section is sent to a terminal in a station adjacent to the station where the train is located.

[0143] Specifically, as described in the aforementioned embodiment, the connected first sensor is also a sensing device that can detect a train, so it is possible to determine whether the connected first sensor detects the passage of a train by collecting information from the first sensor. Optionally, the first sensor may be an electromagnetic sensor, and the collected sensor information is voltage. At this time, if it is determined that the voltage of the connected first sensor begins to change, then it can be determined that the connected first sensor detects the passage of a train. At this time, it can be known that the train has arrived at the starting point of the track section to be entered, and a signal that the train has arrived at the starting point of the section can be sent to the terminal in the next adjacent station of the station, so that the terminal in the next adjacent station knows that the train is about to approach it and returns a signal to prepare to receive the train.

[0144] Receive the signal of being ready to receive the train fed back by the terminal in the next adjacent station to the station where the station is located.

[0145] When it is determined that the connected first sensor detects the departure of a train, a train departure signal is sent to a terminal in a subsequent adjacent station of the station.

[0146] Specifically, when it is determined that the connected first sensor detects the departure of the train, it can be known that the train has been completely dispatched. At this time, a train departure signal can be sent to the terminal in the next adjacent station of the station. Optionally, when the connected first sensor and the second sensor are both electromagnetic sensors, it can be determined by judging whether the number of voltage changes of the second sensor is equal to the number of voltage changes of the first sensor to determine that the connected first sensor has detected the departure of the train.

[0147] Optionally, in the train blocking method provided in the above embodiment, relevant signals transmitted between the terminal in the previous adjacent station and the terminal in the next adjacent station in the station can be transmitted using the RSSP-1 protocol.
