Description

Technical Field

The cab occupancy and train occupancy circuits are typically implemented via relays, and communication between the two cabs is achieved via train lines.

[0037] Figure 1 A schematic diagram of a train cab occupancy control system according to an embodiment of the present disclosure is schematically shown.

[0038] like Figure 1 As shown, the train cab occupancy control system 100 is arranged in a train, and the train includes two cabs at the front and rear, namely a first cab 110 and a second cab 120.

[0039] According to an embodiment of the present disclosure, the train cab occupancy control system 100 includes a first logic control unit 111 provided in a first cab 110 and a second logic control unit 121 provided in a second cab 120 .

[0040] Specifically, the first logic control unit 111 can be used to collect the first occupancy signal of the first driver's cab 110, wherein the first occupancy signal includes a key occupancy signal for representing the key switch state of the first driver's cab 110 and a signal occupancy signal for representing the signal switch state of the first driver's cab 110.

[0041] Specifically, the second logic control unit 121 is used to collect the second occupancy signal of the second driver's cab 120, wherein the second occupancy signal includes a key occupancy signal for representing the key switch state of the second driver's cab 120 and a signal occupancy signal for representing the signal switch state of the second driver's cab 120.

[0042] According to an embodiment of the present disclosure, the first logic control unit 111 may further be configured to receive a second occupancy signal from the second logic control unit 121, and to send a first occupancy signal to the second logic control unit 121. Similarly, the second logic control unit 121 may further be configured to receive a first occupancy signal from the first logic control unit 111, and to send a second occupancy signal to the first logic control unit 111.

[0043] In one embodiment, the first logic control unit 111 and the second logic control unit 121 may exchange information via an internal CAN (Controller Area Network) network.

[0044] Based on this, the first logic control unit 111 and the second logic control unit 121 both include a first occupation signal and a second occupation signal.

[0045] In one embodiment, the first logic control unit 111 and the second logic control unit 121 can both be used to control the occupancy status of the train driver's cab according to the first occupancy signal and the second occupancy signal.

[0046] Specifically, the first logic control unit 111 and the second logic control unit 121 can both be used to control which driver's cab in the train is occupied and whether the driver's cab is occupied by a key or a signal according to the first occupation signal and the second occupation signal.

[0047] The occupancy status may indicate which driver's cab is occupied and whether the driver's cab is occupied by a signal or a key.

[0048] According to the embodiment of the present disclosure, the first logic control unit and the second logic control unit will both collect occupancy signals of their respective driver's cabs to determine whether the key switch or the signal switch in the driver's cab is closed. On this basis, since the key occupancy signal and the signal occupancy signal in the driver's cab are collected separately, effective distinction between signal occupancy and key occupancy is achieved; and, based on the interaction of occupancy signals between the first logic control unit and the second logic control unit, the use of train lines is saved on the basis of realizing variable sharing; since logical judgments are performed by the first logic control unit and the second logic control unit based on the first occupancy signal and the second occupancy signal, it can be used for train driver's cab occupancy control under different working conditions.

[0049] According to an embodiment of the present disclosure, when the train is not occupied, the first logic control unit and the second logic control unit are used to control the occupancy status of the train driver's cab according to the first occupancy signal and the second occupancy signal, including: the first logic control unit and the second logic control unit are used to control the first target driver's cab to be occupied according to the first occupancy signal and the second occupancy signal, wherein the first target driver's cab is one of the first driver's cab and the second driver's cab; when the first target driver's cab is occupied by the key, it is determined that the train is occupied by the key; or when the first target driver's cab is occupied by the signal, it is determined that the train is occupied by the signal.

[0050] According to an embodiment of the present disclosure, the train is not occupied, that is, both the first driver's cab 110 and the second driver's cab 120 are not occupied. When the train is not occupied, the first logic control unit and the second logic control unit can be used to determine whether a driver's cab in the train is occupied based on the first occupation signal and the second occupation signal.

[0051] In one embodiment, when the first logic control unit and the second logic control unit determine that the first target driver's cab is occupied based on the first occupation signal and the second occupation signal, the first target driver's cab may be occupied by a key or by a signal.

[0052] Figure 2 The following schematically shows a logic control diagram of the first target driver's cab being occupied according to an embodiment of the present disclosure.

[0053] like Figure 2 As shown, in the case where the first target driver's cab is occupied by a key or the first target driver's cab is occupied by a signal, it can be indicated that the first target driver's cab is occupied.

[0054] According to an embodiment of the present disclosure, when any one of the first driver's cab and the second driver's cab is occupied, it indicates that the train is occupied.

[0055] Specifically, when the first target driver's cab is occupied by the key, it can be determined that the train is occupied by the key; when the first target driver's cab is occupied by the signal, it can be determined that the train is occupied by the signal.

[0056] Figure 3 The figure schematically shows a logic control diagram of train occupation according to an embodiment of the present disclosure.

[0057] The first target driver's cab may be one of the first driver's cab and the second driver's cab.

[0058] like Figure 3 As shown, in the case where the first target driver's cab is occupied by a key, that is, the first driver's cab is occupied by a key or the second driver's cab is occupied by a key, it can be shown that the train is occupied by a key; in the case where the first target driver's cab is occupied by a signal, that is, the first driver's cab is occupied by a signal or the second driver's cab is occupied by a signal, it can be shown that the train is occupied by a signal.

[0059] According to an embodiment of the present disclosure, when the train is not occupied, the first logic control unit and the second logic control unit can directly determine that the first target driver's cab of the first driver's cab and the second driver's cab is occupied based on the collected first occupation signal and the second occupation signal. On this basis, since one of the driver's cabs at both ends of the train is occupied, it can be determined that the train is occupied. When the first target driver's cab is occupied by a key, it can be determined that the train is occupied by a key. When the first target driver's cab is occupied by a signal, it can be determined that the train is occupied by a signal.

[0060] According to an embodiment of the present disclosure, the first logic control unit and the second logic control unit are used to control the first target driver's cab to be occupied according to the first occupancy signal and the second occupancy signal, including: the first logic control unit and the second logic control unit are used to determine that the key switch state of the first target driver's cab is a closed state according to the first occupancy signal and the second occupancy signal; based on the key switch state of the first target driver's cab being in a closed state, control the first target driver's cab to be occupied by the key.

[0061] According to an embodiment of the present disclosure, the first logic control unit and the second logic control unit can both be used to determine the key switch status and signal switch status in the first and second driver's cabs, respectively, based on the first occupancy signal and the second occupancy signal. The key switch status can indicate whether the key switch is in a closed state or an open state; the signal switch status can indicate whether the signal switch is in a closed state or an open state.

[0062] According to an embodiment of the present disclosure, when the train is not occupied, the first logic control unit and the second logic control unit can directly control which driver's cab is occupied and whether the driver's cab is occupied by a key or a signal based on which switch of which driver's cab is in a closed state determined by the first occupancy signal and the second occupancy signal.

[0063] Specifically, when the first logic control unit and the second logic control unit determine that the key switch state of the first target driver's cab is in the closed state based on the first occupancy signal and the second occupancy signal, it can be determined that the first target driver's cab obtains possession, that is, the first target driver's cab is controlled to be occupied by the key.

[0064] According to an embodiment of the present disclosure, on the basis that the train is not occupied, the first logic control unit and the second logic control unit can perform logical processing on the first occupation signal and the second occupation signal to determine the state of the switch in the driver's cab. When the key switch state of the first target driver's cab among the first and second driver's cabs is closed, a logical variable indicating that the first target driver's cab is occupied by a key can be output, thereby controlling the first target driver's cab to be occupied by a key, thereby realizing control of the train driver's cab occupancy based on different operating conditions. On this basis, it is also effective to distinguish between key occupation and signal occupation of the driver's cab.

[0065] According to an embodiment of the present disclosure, the first logic control unit and the second logic control unit are used to control the first target driver's cab to be occupied according to the first occupancy signal and the second occupancy signal, including: the first logic control unit and the second logic control unit are used to determine that the signal switch state of the first target driver's cab is a closed state according to the first occupancy signal and the second occupancy signal; based on the signal switch state of the first target driver's cab being a closed state, control the first target driver's cab to be occupied by the signal.

[0066] According to an embodiment of the present disclosure, when the train is not occupied, the first logic control unit and the second logic control unit can directly determine which switch of which driver's cab is in a closed state based on the first occupancy signal and the second occupancy signal, and control which driver's cab is occupied and whether the driver's cab is occupied by a key or a signal.

[0067] Specifically, when the first logic control unit and the second logic control unit determine that the signal switch state of the first target driver's cab is in the closed state based on the first occupancy signal and the second occupancy signal, it can be determined that the first target driver's cab obtains the right of occupation, that is, the first target driver's cab is controlled to be occupied by the signal.

[0068] According to an embodiment of the present disclosure, on the basis that the train is not occupied, the first logic control unit and the second logic control unit can perform logical processing on the first occupation signal and the second occupation signal to determine the state of the switch in the driver's cab. When the signal switch state of the first target driver's cab in the first driver's cab and the second driver's cab is closed, a logical variable indicating that the first target driver's cab is occupied by the signal can be output, thereby controlling the first target driver's cab to be occupied by the signal, thereby realizing control of the train driver's cab occupancy based on different operating conditions. On this basis, it is also effective to distinguish between key occupation and signal occupation of the driver's cab.

[0069] According to an embodiment of the present disclosure, when the train is occupied by a signal, the first logic control unit and the second logic control unit are also used to control the signal occupation of the train to be cut off when the key switch state of the first target driver's cab is determined to be in a closed state based on the first occupation signal and the second occupation signal, and to control the first target driver's cab to be occupied by the key and the train to be occupied by the key.

[0070] According to an embodiment of the present disclosure, key possession has a higher priority than signal possession, that is, the key in the driver's cab at either end can cut off the signal possession.

[0071] In one embodiment, when the train has been occupied by a signal, the first logic control unit and the second logic control unit, when determining that the key switch state of the first target driver's cab is closed based on the first occupation signal and the second occupation signal, can determine that the first target driver's cab obtains the right of occupation, that is, control the signal occupation of the train to be cut off, and control the first target driver's cab to be occupied by the key and the train to be switched to be occupied by the key.

[0072] Figure 4 The figure schematically shows a logic control diagram for switching the right of possession when a train is occupied by a signal according to an embodiment of the present disclosure.

[0073] like Figure 4 As shown, regarding the train being occupied by the key C_OUT1, when the logic is established, that is, the train is occupied by the key, C_OUT1 is disconnected; when the logic is not established, that is, the train is not occupied by the key, C_OUT1 is connected.

[0074] Regarding the first target driver's cab being occupied by the key C1_OUT1, when the logic is established, that is, the first target driver's cab is occupied by the key, C1_OUT1 is a passage; when the logic is not established, that is, the first target driver's cab is not occupied by the key, C1_OUT1 is disconnected.

[0075] Thus, when the train is occupied by the signal, that is, the signal switch in the first driver's cab or the second driver's cab is in the closed state. When the key switch state of the first target driver's cab is in the closed state, that is, the key switch of the first target driver's cab is closed, Figure 4 The C_OUT1 shown in FIG is a passage, which enables the first target driver's cab to obtain possession. Therefore, the first logic control unit and the second logic control unit can control the first target driver's cab to be occupied by the key.

[0076] exist Figure 3 In the embodiment, the first driver's cab is occupied by the key or the second driver's cab is occupied by the key, which can indicate that the train is occupied by the key. Therefore, when the first target driver's cab is occupied by the key, the train is occupied by the key.

[0077] exist Figure 4 In the case where the train is occupied by the key, the C_OUT1 is disconnected and the C1_OUT1 is connected, so that the first target driver's cab remains occupied by the key.

[0078] To ensure the safety of train operation, only one driver's cab is allowed to be occupied at the same time. Therefore, while the first logic control unit and the second logic control unit control the first target driver's cab to be occupied by the key, it is necessary to control the signal occupation of the train to be cut off.

[0079] Figure 5 The following schematically shows a logic control diagram for cutting off the signal occupation of a train when the train is occupied by a signal according to an embodiment of the present disclosure.

[0080] like Figure 5 As shown, regarding the train being occupied by the signal C_OUT2, when the logic is established, that is, the train is occupied by the signal, C_OUT2 is disconnected; when the logic is not established, that is, the train is not occupied by the signal, C_OUT2 is a passage.

[0081] Regarding the driver's cab being occupied by the signal C1_OUT2, when the logic is established, that is, the driver's cab is occupied by the signal, C1_OUT2 is a passage; when the logic is not established, that is, the driver's cab is not occupied by the signal, C1_OUT2 is disconnected.

[0082] exist Figure 5 In the case of the train being occupied by the signal, the signal switch in the driver's cab is in the closed state, that is, the signal switch in the first driver's cab or the second driver's cab is in the closed state. Since the train is occupied by the signal, the C_OUT2 is disconnected and the C1_OUT2 is open. However, based on Figure 4 As shown, the train has been occupied by the key, so Figure 5 The train is occupied by the key C_OUT1 is disconnected, which cuts off the driver's cab from being occupied by the signal.

[0083] According to an embodiment of the present disclosure, when a train has been occupied by a signal, since the priority of the key possession of the driver's cab is higher than the signal possession, when the first logic control unit and the second logic control unit determine that the key switch state of the first target driver's cab in the first driver's cab and the second driver's cab is in the closed state based on the first possession signal and the second possession signal, the train possession can be switched from the train signal possession to the key possession. In this way, the control of the train driver's cab possession based on different working conditions is realized. Moreover, based on the effective distinction between the key possession and signal possession of the train driver's cab, the switching between signal possession and key possession can be realized.

[0084] According to an embodiment of the present disclosure, when a train is occupied by a key, the first logic control unit and the second logic control unit are also used to control the train to remain occupied by the key when it is determined that the key switch state of the first target driver's cab is in a closed state or the signal switch state is in a closed state based on the first occupation signal and the second occupation signal.

[0085] According to an embodiment of the present disclosure, the train is occupied by a key, that is, the key switch in the first driver's cab or the second driver's cab is in a closed state.

[0086] Since the possession of the key to the driver's cab has a higher priority than signal possession, when the train is occupied by the key, even if the first logic control unit and the second logic control unit determine that the key switch state of the first target driver's cab is closed or the signal switch state is closed according to the first possession signal and the second possession signal, the first target driver's cab cannot obtain possession, that is, the train is controlled to maintain key possession.

[0087] Specifically, the occupied driver's cab corresponding to the train being occupied by the key and the first target driver's cab may be the same driver's cab or different driver's cabs.

[0088] Figure 6 The figure schematically shows a logic control diagram for maintaining key possession when a train is occupied by a key according to an embodiment of the present disclosure.

[0089] like Figure 6 As shown, when the first target driver's cab and the driver's cab corresponding to the train occupied by the key are not the same driver's cab, the key switch of the first target driver's cab is closed. Since the train is occupied by the key, the C_OUT1 is disconnected and the C1_OUT1 is also disconnected. Therefore, the first target driver's cab cannot obtain possession, that is, the first target driver's cab cannot be occupied by the key, and the train remains occupied by the key.

[0090] Therefore, in the case where the key switches of the driver's cabs at both ends of the train are turned off, the driver's cab at one end that turns off the key switch first obtains the right of occupation.

[0091] Regarding the closing of the signal switch of the first target driver's cab, the first target driver's cab may be the same driver's cab as the driver's cab corresponding to the train occupied by the key, or may not be the same driver's cab.

[0092] Specifically, the signal switch of the first target driver's cab is closed. Since the train is occupied by the key, C_OUT2 is connected, C1_OUT2 is disconnected, and C_OUT1 is disconnected. Therefore, the first target driver's cab cannot be occupied by the signal, and the train remains occupied by the key.

[0093] According to an embodiment of the present disclosure, when a train has been occupied by a key, since the priority of the key occupation of the driver's cab is higher than the signal occupation and when the key switches of the driver's cabs at both ends are closed, the end that is closed first obtains the occupation right, when the first logic control unit and the second logic control unit judge that the key switch state of the first target driver's cab in the first driver's cab and the second driver's cab is in a closed state or the signal switch state is in a closed state based on the first occupation signal and the second occupation signal, the train is maintained in the possession of the key, thereby achieving the maintenance of the possession right.

[0094] According to an embodiment of the present disclosure, when the first target driver's cab is occupied by a key, the first logic control unit and the second logic control unit are further used to control the first target driver's cab to remain occupied by the key and the train to remain occupied by the key when it is determined that the signal switch state of the second target driver's cab is in a closed state or the key switch state is in a closed state; wherein the second target driver's cab is one of the first driver's cab and the second driver's cab.

[0095] According to an embodiment of the present disclosure, the train is not occupied, and the first logic control unit and the second logic control unit control the first target driver's cab to be occupied by the key based on the first occupation signal and the second occupation signal. The first logic control unit and the second logic control unit can also be used to control the first target driver's cab to remain occupied by the key and the train to remain occupied by the key when it is determined that the signal switch state of the second target driver's cab is in a closed state or the key switch state is in a closed state.

[0096] In one embodiment, the second target driver's cab and the first target driver's cab may be the same driver's cab or may not be the same driver's cab.

[0097] See also Figure 3 , when the first target driver's cab is occupied by the key, it indicates that the train is occupied by the key.

[0098] When the first logic control unit and the second logic control unit determine that the key switch state of the second target driver's cab is the closed state, the second target driver's cab and the first target driver's cab are not the same driver's cab.

[0099] Specifically, see Figure 6 , the second target driver's cab cannot obtain possession, the first target driver's cab remains occupied by the key, and the train also remains occupied by the key.

[0100] When the first logic control unit and the second logic control unit determine that the signal switch state of the second target driver's cab is closed, the second target driver's cab and the first target driver's cab may be the same driver's cab or may not be the same driver's cab.

[0101] Specifically, see Figure 6 , the second target cab cannot be occupied by the signal, that is, the first target cab remains occupied by the key, and the train also remains occupied by the key.

[0102] According to an embodiment of the present disclosure, when the first target driver's cab is already occupied by a key, since the key occupation of the driver's cab has a higher priority than the signal occupation and when the key switches of the driver's cabs at both ends are closed, the end that is closed first obtains the occupation right, when the first logic control unit and the second logic control unit judge that the key switch state of the second target driver's cab in the first driver's cab and the second driver's cab is in a closed state or the signal switch state is in a closed state, the first target driver's cab is maintained to be occupied by the key and the train is maintained to be occupied by the key, thereby achieving the maintenance of the occupation right.

[0103] According to an embodiment of the present disclosure, when the first target driver's cab is occupied by a signal, the first logic control unit and the second logic control unit are also used to control the cutting off of the signal occupation of the first target driver's cab and the signal occupation of the train when it is determined that the key switch state of the second target driver's cab is in a closed state, and control the second target driver's cab to be occupied by the key and the train to be occupied by the key.

[0104] According to an embodiment of the present disclosure, the train is not occupied, and the first logic control unit and the second logic control unit control the first target driver's cab to be occupied by the signal based on the first occupation signal and the second occupation signal. The first logic control unit and the second logic control unit can also be used to cut off the signal occupation of the first target driver's cab and the signal occupation of the train when it is determined that the key switch state of the second target driver's cab is in a closed state, and control the second target driver's cab to be occupied by the key and the train to be occupied by the key.

[0105] In one embodiment, the second target driver's cab and the first target driver's cab may be the same driver's cab or may not be the same driver's cab.

[0106] See also Figure 3 , when the first target driver's cab is occupied by the signal, it indicates that the train is occupied by the signal.

[0107] When the first logic control unit and the second logic control unit determine that the key switch state of the second target driver's cab is in the closed state, since the possession authority of the driver's cab key is greater than the signal possession, the key of the second target driver's cab can cut off the signal possession of the first target driver's cab and cut off the signal possession of the train.

[0108] See also Figure 6 When it is determined that the key switch of the second target driver's cab is closed, the signal occupation of the first target driver's cab can be cut off, and the second target driver's cab can be controlled to be occupied by the key.

[0109] Figure 7 The following schematically shows a logic control diagram of train occupancy when the first target driver's cab is occupied according to an embodiment of the present disclosure.

[0110] like Figure 7 As shown, when the first target cab is occupied by the signal, that is, the first cab is occupied by the signal or the second cab is occupied by the signal, the train is occupied by the signal. When the key switch of the second target cab is closed, the train can be controlled to be occupied by the key and the train is cut off from being occupied by the signal.

[0111] According to an embodiment of the present disclosure, when the first target driver's cab has been occupied by a signal, since the priority of the key possession of the driver's cab is higher than the signal possession, when the first logic control unit and the second logic control unit determine that the key switch state of the second target driver's cab in the first driver's cab and the second driver's cab is in a closed state, the switching of the driver's cab possession and the train possession can be realized, switching from the first target driver's cab to the second target driver's cab and from the train signal possession to the key possession. In this way, the control of the train driver's cab possession based on different working conditions is realized. Moreover, based on the effective distinction between the key possession and signal possession of the train driver's cab, the switching of signal possession and key possession can be realized.

[0112] According to an embodiment of the present disclosure, when the first target driver's cab is occupied by a signal, the first logic control unit and the second logic control unit are also used to control the first target driver's cab to maintain being occupied by the signal and the train to maintain signal occupation when it is determined that the signal switch state of the second target driver's cab is in a closed state, and the second target driver's cab does not obtain occupation.

[0113] According to an embodiment of the present disclosure, when the first target cab is occupied by a signal, the first logic control unit and the second logic control unit determine that the signal switch state of the second target cab is closed. Figure 6 , the first target cab is still occupied by the signal, see Figure 7 , the train remains occupied by the signal and the second target driver's cab does not obtain possession.

[0114] According to an embodiment of the present disclosure, when the first target driver's cab has been occupied by the signal, since the end that closes the signal switch first obtains the occupation right when both end driver's cabs close the signal switch, the first logic control unit and the second logic control unit control the first target driver's cab to maintain being occupied by the signal and the train to maintain signal occupation based on the judgment that the signal switch status of the second target driver's cab in the first driver's cab and the second driver's cab is in a closed state, and the second target driver's cab does not obtain the occupation right, thereby realizing the maintenance of the occupation right.

[0115] Figure 8 A schematic diagram of a train cab occupancy control circuit according to an embodiment of the present disclosure is schematically shown.

[0116] like Figure 8 As shown, the train cab occupancy control circuit includes a key switch 801, a signal switch 802, a power supply 803 and a logic control unit 810. The logic control unit 810 can be Figure 1 As shown in the first logic control unit 111 and the second logic control unit 121, the first driver's cab 110 and the second driver's cab 120 are both provided with Figure 8 The train driver's cab shown holds the control circuits.

[0117] The input voltage range of the power supply 803 may be 0V to 110V.

[0118] According to an embodiment of the present disclosure, the first end of the key switch 801 is connected to the positive pole of the power supply 803, and the second end of the key switch 801 is connected to the logic control unit 810; the first end of the signal switch 802 is connected to the positive pole of the power supply 803, and the second end of the signal switch 802 is connected to the logic control unit 810; the logic control unit 810 is connected to the negative pole of the power supply 803.

[0119] In one embodiment, the logic control unit 810 is used to: collect a first occupancy signal of the first driver's cab, the first occupancy signal including a key occupancy signal for representing the key switch status of the first driver's cab and a signal occupancy signal for representing the signal switch status of the first driver's cab; receive a second occupancy signal from the logic control unit of the second driver's cab, the second occupancy signal including a key occupancy signal for representing the key switch status of the second driver's cab and a signal occupancy signal for representing the signal switch status of the second driver's cab; and control the occupancy status of the train driver's cab according to the first occupancy signal and the second occupancy signal.

[0120] According to the embodiments of the present disclosure, the logic control unit in the train cab occupancy control circuit collects the cab occupancy signal to determine whether the key switch or the signal switch in the cab is closed. Based on this, by separately collecting the key occupancy signal and the signal occupancy signal in the cab, effective distinction between signal occupancy and key occupancy is achieved. Since the logic control unit performs logical judgment based on the first occupancy signal and the second occupancy signal, it can be used for train cab occupancy control under different operating conditions. Furthermore, the train cab occupancy control circuit utilizes the logic control unit to achieve variable sharing, saving the use of train lines and having high redundancy and reliability.

[0121] Based on the above content, the train cab occupancy control circuit is implemented through a logic control unit. Relays and train lines are not set up separately, so that the interactive variables can be recorded and monitored in real time within the logic control unit. When a train fault occurs, the fault point can be located in time, greatly improving the circuit availability.

[0122] Figure 9 A flow chart of a train driver's cab occupancy control method according to an embodiment of the present disclosure is schematically shown.

[0123] like Figure 9 As shown, the method 900 includes operations S910 to S940.

[0124] The train cab occupancy control method 900 can be applied to Figure 1 The train cab occupancy control system 100 is shown in FIG.

[0125] In operation S910, a first occupancy signal of a first driver's cab is collected using a first logic control unit.

[0126] The first occupancy signal includes a key occupancy signal for representing the key switch state of the first driver's cab and a signal occupancy signal for representing the signal switch state of the first driver's cab.

[0127] In operation S920, a second occupancy signal of the second driver's cab is collected by using the second logic control unit.

[0128] The second occupancy signal includes a key occupancy signal for representing the key switch state of the second driver's cab and a signal occupancy signal for representing the signal switch state of the second driver's cab.

[0129] In operation S930 , the first logic control unit receives a second occupancy signal from the second logic control unit and transmits a first occupancy signal to the second logic control unit.

[0130] In operation S940, the occupancy status of the train driver's cab is controlled according to the first occupancy signal and the second occupancy signal by using the first logic control unit and the second logic control unit.

[0131] According to the embodiment of the present disclosure, the first logic control unit and the second logic control unit will both collect occupancy signals of their respective driver's cabs to determine whether the key switch or the signal switch in the driver's cab is closed. On this basis, since the key occupancy signal and the signal occupancy signal in the driver's cab are collected separately, effective distinction between signal occupancy and key occupancy is achieved; and, based on the interaction of occupancy signals between the first logic control unit and the second logic control unit, the use of train lines is saved on the basis of realizing variable sharing; since logical judgments are performed by the first logic control unit and the second logic control unit based on the first occupancy signal and the second occupancy signal, it can be used for train driver's cab occupancy control under different working conditions.
