[0002] With the development of new energy technology, the use of hydrogen energy to provide energy supply for rail transit vehicles has become a new trend. During the process of replacing rail transit vehicles with new energy, if the hydrogen energy rail transit vehicle loses power, the control circuit will lose power supply, and the personnel on the rail transit vehicle will not be able to close the valve of the hydrogen energy container through the control circuit, which will lead to hydrogen energy leakage and even more serious safety risks.

[0018] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] In an alternative embodiment, if Figure 1 As shown, a rail transit vehicle energy replacement system is provided. In this embodiment, the system includes a replacement tool 110 and an energy control device 120; The replacement tool 110 includes a battery 111, a first power converter 112, a second power converter 113, a temperature gauge 114, a pressure gauge 115, a replacement switch 116 and a bottle valve status light 117; The energy control device 120 includes a main controller 121, a bottle valve 122 and an energy container 123; The storage battery 111 is connected to the input end of the first power converter 112; the output end of the first power converter 112 is connected to the input end of the second power converter 113; the input end of the temperature gauge 114 and the input end of the pressure gauge 115 are connected in parallel to the output end of the second power converter 113; the output end of the temperature gauge 114 and the output end of the pressure gauge 115 are both connected to the input end of the main controller 121; The replacement switch 116 and the bottle mouth valve status light 117 are both located on the connection line between the output end of the second power converter 113 and the input end of the main controller 121; The bottle mouth valve 122 is located on the connection line between the output end of the main controller 121 and the input end of the energy container 123 .

[0020] Exemplarily, the battery 111 can be an AC220V battery, and the first power converter 112 can be an AC220V / DC110V power converter, so as to convert the input voltage provided by the battery into a 110V output voltage; the second power converter 113 can be an AC110V / DC240V power converter, so as to convert the input voltage provided by the first power converter into a 240V output voltage.

[0021] Optionally, a spare replacement switch 118 may be provided on a parallel line of the connection line where the replacement switch 116 is located, and when the replacement switch 116 fails, the spare replacement switch 118 may be enabled; a spare status light 119 may be provided on a parallel line of the connection line where the bottle mouth valve status light 117 is located, and when the bottle mouth valve status light 117 fails, the spare status light 119 may be enabled.

[0022] It should be noted that when a power outage occurs on the entire vehicle, the original power supply system of the system cannot provide power supply, and the replacement switch 116 is controlled to be closed so that the battery 111 can supply power to the system; correspondingly, when the rail transit vehicle is in a normal power supply state, the replacement switch 116 remains disconnected, and power is supplied to the system through the original power supply system.

[0023] In an alternative embodiment, if Figure 2 As shown, a method for replacing energy for a rail transit vehicle is provided. In this embodiment, the method is applied to Figure 1 The method comprises the following steps: S110, determining whether the rail transit vehicle should perform energy replacement according to the display status of the bottle valve status light.

[0024] Among them, when the bottle mouth valve status light is on, it means that the bottle mouth valve is in the open state and the rail transit vehicle is undergoing energy replacement; when the bottle mouth valve status light is not on, it means that the bottle mouth valve is in the closed state and the rail transit vehicle is not undergoing energy replacement. Furthermore, energy replacement for rail transit vehicles can be understood as replenishing energy in the energy container.

[0025] S120: If the displayed status indicates that the rail transit vehicle is undergoing energy replacement, the energy status of the rail transit vehicle is obtained.

[0026] The energy state of a rail transit vehicle can be understood as the power supply state of the rail transit vehicle system. The energy state of a rail transit vehicle can include the whole vehicle power-off state and the normal power supply state. The whole vehicle power-off state can be understood as the original power supply system being unable to supply power to the rail transit vehicle system normally.

[0027] S130, if the energy state of the rail transit vehicle is the whole vehicle power-off state, the replacement switch is controlled to be closed; after the replacement switch is closed, the bottle mouth valve is controlled to be closed, so that the rail transit vehicle ends the energy replacement.

[0028] It is understandable that if the rail transit vehicle is in the process of energy replacement, the energy state of the rail transit vehicle is in the state of vehicle power failure, and the bottle mouth valve of the energy container cannot be closed in time, there is a great risk of energy leakage. In this case, the replacement switch can be controlled to close first to restore the power supply of the rail transit vehicle energy replacement system, and then the bottle mouth valve can be controlled to close, so as to avoid energy leakage in time.

[0029] S140, if the energy state of the rail transit vehicle is a normal power supply state, a first internal temperature value and a first pipeline pressure value of the energy container are obtained in real time; and the opening and closing state of the bottle mouth valve is controlled according to the first internal temperature value and the first pipeline pressure value.

[0030] During the energy replacement process of the rail transit vehicle, if the energy state of the rail transit vehicle is in a normal power supply state, it is necessary to monitor the internal state of the energy container and the state of the energy pipeline to avoid the energy replacement lasting too long, causing damage to the energy container and the energy pipeline, and preventing energy leakage. Among them, the first internal temperature value can be understood as the temperature value inside the energy container during the energy replacement process, and the first pipeline pressure value can be understood as the pressure value inside the energy pipeline during the energy replacement process.

[0031] In an optional embodiment, the method for controlling the opening and closing state of the bottle mouth valve according to the first internal temperature value and the first pipeline pressure value may include: If the first internal temperature value is greater than the first preset temperature value, or the first pipeline pressure value is greater than the first preset pressure value, the bottle mouth valve is controlled to close and an abnormal alarm is issued; If the internal temperature value is less than or equal to the first preset temperature value, and the pipeline pressure value is less than or equal to the first preset pressure value, the bottle mouth valve is controlled to remain open.

[0032] Among them, the first preset temperature value and the first preset pressure value can be set by the technicians according to experience or actual needs, and are not limited here. When the first internal temperature value is greater than the first preset temperature value, it means that the internal temperature of the energy container is too high, and it is necessary to stop the energy replacement to reduce the internal temperature of the energy container; when the first pipeline pressure value is greater than the first preset pressure value, it means that the internal pressure of the energy pipeline is too high, and it is necessary to stop the energy replacement to avoid cracking of the energy pipeline; in the above two cases, the bottle mouth valve can be controlled to close and an abnormal alarm can be issued.

[0033] Furthermore, if the internal temperature value is less than or equal to the first preset temperature value, and the pipeline pressure value is less than or equal to the first preset pressure value, it means that the internal temperature of the energy container is not too high, and the internal pressure of the energy pipeline is not too high. Therefore, the bottle mouth valve can be controlled to remain open to continue energy replacement.

[0034] In an optional embodiment, if the display status of the bottle mouth valve status light indicates that the rail transit vehicle has not performed energy replacement, the second internal temperature value and the second pipeline pressure value of the energy container are obtained in real time; according to the second internal temperature value and the second pipeline pressure value, the opening and closing state of the bottle mouth valve is controlled.

[0035] Among them, the second internal temperature value can be understood as the temperature value inside the energy container when the rail transit vehicle does not perform energy replacement; the second pipeline pressure value can be understood as the pressure value inside the energy pipeline when the rail transit vehicle does not perform energy replacement.

[0036] Optionally, the method for controlling the opening and closing state of the bottle mouth valve according to the second internal temperature value and the second pipeline pressure value may include: If the second internal temperature value is less than or equal to the first preset temperature value, and the second pipeline pressure value is less than or equal to the second preset pressure value, the bottle mouth valve is controlled to open; the second preset pressure value is less than the first preset pressure value; If the second internal temperature value is less than or equal to the first preset temperature value, and the second pipeline pressure value is greater than the second preset pressure value, the bottle mouth valve is controlled to remain closed, and further determine whether to issue an abnormal alarm; If the second internal temperature value is greater than the first preset temperature value, the bottle mouth valve is controlled to remain closed and an abnormal alarm is issued.

[0037] Among them, the second preset pressure value can be set by the technician according to experience or actual needs, and is not limited here. It can be understood that when the second internal temperature value is greater than the first preset temperature value, it means that when the rail transit vehicle does not perform energy replacement, the internal temperature of the energy container is already too high, and it is necessary to control the bottle mouth valve to remain closed and issue an alarm; when the second pipeline pressure value is greater than the second preset pressure value, it means that when the rail transit vehicle does not perform energy replacement, the pressure in the energy pipeline is not too low, and there is no need to replenish energy inside the energy container, so the bottle mouth valve can be controlled to remain closed. However, if the second pipeline pressure value is greater than the first preset pressure value in addition to being greater than the second preset pressure value, it means that the pressure value inside the energy pipeline is too large, and it is necessary to issue an alarm while controlling the bottle mouth valve to remain closed.

[0038] In addition, when the second internal temperature value is less than or equal to the first preset temperature value, it means that the internal temperature of the energy container is not too high when the rail transit vehicle does not perform energy replacement; when the second pipeline pressure value is less than or equal to the second preset pressure value, it means that the pressure value inside the energy pipeline is too low when the rail transit vehicle does not perform energy replacement; therefore, when the above two conditions are met at the same time, the bottle mouth valve can be controlled to open, so as to replenish energy into the energy container.

[0039] In this embodiment, whether the rail transit vehicle is performing energy replacement is determined according to the display status of the bottle mouth valve status light; if the display status indicates that the rail transit vehicle is performing energy replacement, the energy status of the rail transit vehicle is obtained; if the energy status of the rail transit vehicle is a power-off state of the entire vehicle, the replacement switch is controlled to be closed; after closing the replacement switch, the bottle mouth valve is controlled to be closed, so that the rail transit vehicle ends the energy replacement to avoid energy leakage problems caused by untimely closure of the bottle mouth valve; if the energy status of the rail transit vehicle is a normal power supply state, the first internal temperature value and the first pipeline pressure value of the energy container are obtained in real time; according to the first internal temperature value and the first pipeline pressure value, the opening and closing state of the bottle mouth valve is controlled to ensure the stable and safe operation of the energy replacement system.

Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
