Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.
The inventor finds that in the research of the motor train unit, when the motor train unit is in an unmanned state, the power supply dormancy and awakening of the motor train unit need to be effectively controlled, and appropriate treatment measures are taken according to the equipment fault condition and the working condition of the storage battery. Moreover, in some application scenarios, for example, in a special scenario of a new airport line, a dead zone exists in a station, and the train needs to be started by a storage battery, so that the electric quantity of the storage battery needs to be monitored to ensure that the storage battery has enough electric quantity to ensure that the train can be started the next day.
Based on this, the embodiment of the application provides a train power supply method, when a train is in a static state, the remaining power of a storage battery in the train is obtained, and the available duration is determined according to the remaining power and the power consumption of the vehicle-mounted equipment which is still in a working state at present. And when the available duration is less than the preset duration, sending a power-off instruction to the vehicle-mounted equipment in the working state, so that the vehicle-mounted equipment is powered off according to the power-off instruction and is in the power-off state. Namely, when the electric quantity of the storage battery is not enough to maintain the vehicle-mounted equipment in the working state to restart the train, the power is not supplied to the vehicle-mounted equipment any more, so that the enough electric quantity is ensured to ensure that the train can be started next day, and the reliability and the safety of the train operation are further ensured.
It should be noted that the method of this embodiment may be applied to a vehicle-mounted network system of a train, and the vehicle-mounted network system may be respectively communicated with a battery monitoring device, a vehicle-mounted device, and a ground communication device.
In order to facilitate understanding of the technical solutions provided by the present application, the train power supply method provided by the present application will be described below with reference to the accompanying drawings.
Referring to fig. 1, which is a flowchart of a train power supply method provided in an embodiment of the present application, as shown in fig. 1, the method may include:
s101: and acquiring the residual electric quantity of the storage battery in the train.
S102: and determining the available time length according to the residual electric quantity and the electricity consumption of the vehicle-mounted equipment in the working state.
In this embodiment, when the train stops operating, the current remaining power of the storage battery in the train is obtained, and the available duration is determined according to the remaining power and the power consumption of the on-board device currently in the operating state. Namely, the available time length of the storage battery is obtained by dividing the residual capacity of the storage battery by the total power consumption of all the currently-operated vehicle-mounted devices. The power consumption of the on-board device in the operating state is the power consumption of the on-board device per hour. The vehicle-mounted equipment can comprise equipment such as a vehicle-mounted purifier, a vehicle-mounted massager, a vehicle-mounted dust collector and the like.
For example, if the remaining amount of the battery is a, the used amount of the on-vehicle device 1 in the operating state is x1, the used amount of the on-vehicle device 2 in the operating state is x2, and the used amount of the on-vehicle device 3 in the operating state is x3, the usable time period of the battery is a/(x1+ x2+ x 3).
In practical application, the battery monitoring device can monitor parameters such as electric quantity and voltage of the storage battery in real time, and the vehicle-mounted network system can acquire the parameters from the battery monitoring device so as to perform corresponding processing according to the parameters.
S103: and when the available duration is less than the preset duration, sending a power-off instruction so that the vehicle-mounted equipment in the working state is in a power-off state.
After the available time of the storage battery is determined, whether the available time is less than a preset time is judged, if the available time is less than the preset time, the fact that the storage battery cannot maintain the work of the current vehicle-mounted equipment is indicated, if the power supply of the current vehicle-mounted equipment is continued, the normal start of the train in the next day cannot be guaranteed, a power-off instruction is sent to the current vehicle-mounted equipment, so that the vehicle-mounted equipment in the working state is in the power-off state, power consumption is not continued, the normal start of the train is guaranteed, and the reliability of the train operation. The preset time length may be set according to an actual situation, for example, 12 hours or 24 hours, and specifically, the preset time length may be a time length from a train shutdown time to a next train startup time.
It can be understood that when the available duration is longer than the preset duration, it indicates that the remaining capacity of the storage battery can maintain normal operation of the vehicle-mounted equipment currently in the operating state and can ensure restart of the train, and then no operation is required. At this time, the vehicle-mounted network system can receive the awakening instruction sent by the ground communication equipment to carry out pantograph-ascending current collection on the train.
In a possible implementation manner, after the available duration of the storage battery is judged to be less than the preset duration, the voltage of the storage battery is monitored instead of immediately sending the power-off instruction to the vehicle-mounted device, the size relation between the voltage of the storage battery and the preset voltage is judged, and whether the power-off instruction is sent to the vehicle-mounted device or not is determined according to the judgment result. Specifically, when the available duration is less than the preset duration, whether the voltage of the storage battery is less than the preset voltage is judged, and if yes, a power-off instruction is sent. When the available time of the storage battery is less than the preset time, the voltage of the storage battery is detected to be less than the preset voltage, the power supply capacity of the storage battery is very small, a power-off instruction is sent to all vehicle-mounted equipment in the current working state, all power-consuming equipment is stopped, and a charging instruction is sent to a ground system at the same time, so that the storage battery is charged through manual operation, the electric quantity of the storage battery can be further used for starting a train next time, and the running reliability of the train is guaranteed. The preset voltage may be set according to an actual application condition, and the present embodiment is not limited herein, for example, the preset voltage obtained through multiple tests is 84 volts.
In addition, when the voltage of the storage battery is detected to be larger than the preset voltage, the storage battery is still usable, a power-off instruction does not need to be sent to the vehicle-mounted equipment, and a charging instruction is directly sent to the ground communication equipment, so that the storage battery is charged by a worker.
In addition, when the train is in a stop state, the working condition of the vehicle-mounted equipment can be detected to determine the safety of the train. Specifically, the vehicle-mounted network system sends a self-checking instruction to each vehicle-mounted device, so that the vehicle-mounted device performs self-checking according to the self-checking instruction; and receiving the self-checking results sent by each piece of vehicle-mounted equipment, and sending a power-off instruction to the vehicle-mounted equipment with the self-checking result of no fault. Namely, a power-off instruction is sent to the vehicle-mounted equipment which is self-detected to be fault-free.
When the self-checking result of the vehicle-mounted equipment indicates that a fault exists, the vehicle-mounted network system sends a restarting instruction to the vehicle-mounted equipment with the fault self-checking result, so that after the vehicle-mounted equipment is restarted, the vehicle-mounted network system sends the self-checking instruction to the vehicle-mounted equipment again and receives the self-checking result sent by the vehicle-mounted equipment. And when the self-checking result of the vehicle-mounted equipment is still a fault, sending a fault instruction to the ground communication equipment so that ground workers can maintain the vehicle-mounted equipment according to the fault instruction. The fault instruction comprises the identification of the vehicle-mounted equipment, so that a worker can determine the specific vehicle-mounted equipment, and the vehicle-mounted equipment corresponding to the identification can be maintained.
Through the above description, in the embodiment of the application, the remaining capacity of the storage battery in the train is firstly obtained, and then the available duration of the storage battery is determined according to the remaining capacity of the storage battery and the vehicle-mounted device currently in the working state. And then, judging the relation between the available time length and the preset time length of the storage battery, if the relation is less than the preset time length, indicating that the storage battery cannot continuously supply power to the vehicle-mounted equipment in the working state within the preset time length, and sending a power-off instruction to the vehicle-mounted equipment in the working state so as to enable the vehicle-mounted equipment to be in the power-off state and not consume electric quantity, thereby ensuring that the electric quantity in the storage battery can maintain the start of the train.
For convenience of understanding, referring to fig. 2, a frame diagram of train power supply is shown, specifically, a vehicle-mounted network system sends a sleep instruction to each vehicle-mounted device, and the vehicle-mounted device performs self-checking after receiving the sleep instruction. If the self-checking result of the vehicle-mounted equipment is a fault, the self-checking is unqualified, the vehicle-mounted equipment is forcibly powered off, and the vehicle-mounted equipment is restarted to continuously control the vehicle-mounted equipment to perform self-checking operation. If the self-checking result of the vehicle-mounted equipment is no fault, the self-checking is qualified, the vehicle-mounted equipment is powered off and dormant, and only the vehicle-mounted equipment which is communicated with the ground is kept in a working state. Meanwhile, the vehicle-mounted network system acquires the residual electric quantity of the storage battery from the battery monitoring system, determines whether the current residual electric quantity can support the preset time length or not, and can receive the awakening instruction sent by the ground at the preset time point if the current residual electric quantity can support the preset time length. If the battery can not support the preset duration, judging whether the voltage of the storage battery is greater than the preset voltage, and if so, sending a charging instruction to the ground communication equipment to perform manual operation. And if the voltage of the storage battery is smaller than the preset voltage, sending a power-off instruction to all vehicle-mounted equipment in the working state, and sending a charging instruction to the ground communication equipment.
