[0002] Locomotives and vehicles in the rail transit field, including engineering vehicle series models, are equipped with lighting systems in the driver's cab, mechanical room and other driver and passenger activity areas. Their function is to turn on the lighting system switch and light up the lighting system after the driver and passengers board the vehicle and the entire vehicle is powered on, so that the driver and passengers can carry out other activities.

[0003] Currently, the power supply for the lighting system of rolling stock usually comes from the vehicle's low-voltage power supply, which is generally DC110V or DC24V. The existing lighting system has the following problems:

[0004] The lighting system can only be activated after the driver and passengers open the doors and board the vehicle, and turn on the vehicle's low-voltage power control switch and the switches for various lights (such as the driver's cabin light and the engine room light). Drivers and passengers still need to complete this phase of operation without lighting, which is not only inconvenient but also poses a risk of falling, affecting their personal safety. Summary of the Invention

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0030] Figure 2 This is a flow chart of a control method for a boarding welcome lighting system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0032] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] like Figure 1 As shown, the present embodiment provides a boarding welcome lighting system, comprising a conversion power module, a backup energy storage module, a plurality of welcome lights, a plurality of door touch switches and a control module; the plurality of door touch switches are respectively arranged in the door gaps of each workroom, the plurality of welcome lights are respectively arranged in each workroom, and the door touch switches and the welcome lights of the same workroom correspond to each other; the input end of the conversion power module is connected to the output end of the vehicle's low-voltage power supply, and the output end of the conversion power module is connected to the input end of the backup energy storage module and the input end of the control module; the output end of the backup energy storage module is connected to the power end of the control module and each door touch switch; the control module is also connected to the drive circuit of each door touch switch and each welcome light.

[0034] The conversion power supply module is used to detect the status of the vehicle's low-voltage power supply based on the output voltage of the vehicle's low-voltage power supply, send the status signal of the vehicle's low-voltage power supply to the control module, and when the vehicle's low-voltage power supply is in a working state, convert the output voltage of the vehicle's low-voltage power supply into the rated voltage of the backup energy storage module to charge the backup energy storage module.

[0035] For example, the output voltage of the vehicle's low-voltage power supply is DC110V, and the rated voltage of the backup energy storage module is 12V. When the voltage output by the vehicle's low-voltage power supply to the conversion power supply module is greater than or equal to the set voltage, the conversion power supply module detects that the vehicle's low-voltage power supply is in an operating state, sends a status signal of the vehicle's low-voltage power supply (assuming the status signal at this time is positive) to the control module, and simultaneously converts the DC110V to 12V to charge the backup energy storage module. When the voltage output by the vehicle's low-voltage power supply to the conversion power supply module is less than the set voltage, the conversion power supply module detects that the vehicle's low-voltage power supply is in an inoperative state and sends a status signal of the vehicle's low-voltage power supply (assuming the status signal at this time is negative) to the control module. In this embodiment, the set voltage is DC77V.

[0036] The backup energy storage module is used to provide power to each door touch switch, control module, and each welcome light. In a specific embodiment of the present invention, the backup energy storage module is a backup battery, which uses a lithium phosphate battery with a capacity of 6000mAH and a rated voltage of DC12V.

[0037] The door touch switch is an inductive switch installed in the gap of the studio door. Its working principle is that when the door is closed, the door touch switch is in the open state and the door touch switch outputs a normally open signal; when the door is open, the door touch switch is in the closed state and the door touch switch outputs a closed signal. Each door touch switch is used to detect the door status of each studio. When the door touch switch is in the open state, the corresponding studio door is closed (that is, the door status signal is off), and the door touch switch status signal is "negative"; when the door touch switch is in the closed state, the corresponding studio door is open (that is, the door status signal is open), and the door touch switch status signal is "positive". In a specific embodiment of the present invention, there are 6 door touch switches (i.e., K1 to K6), and the studio includes the driver's cab at end I, the driver's cab at end II, the mechanical room at end I, and the mechanical room at end II. The driver's cab at end I and the driver's cab at end II each have two doors, and each door corresponds to a door touch switch, that is, the driver's cab at end I and the driver's cab at end II are each provided with 2 door touch switches, and the mechanical room at end I and the mechanical room at end II are each provided with a door touch switch, for a total of 6 door touch switches. Each door touch switch is provided at the door gap of the corresponding door, and is used to detect the door status of the driver's cab at end I, the driver's cab at end II, the mechanical room at end I, and the mechanical room at end II. For example, when the door touch switches at all the door gaps of the driver's cab at end I are in the open state, the door of the driver's cab at end I is in the closed state; when the door touch switches at any door gap of the driver's cab at end I is in the closed state, the door of the driver's cab at end I is in the open state.

[0038] Each welcome light is used to illuminate each workroom. In one embodiment of the present invention, there are four welcome lights (i.e., LEDs 1 to 4). The workroom includes a driver's cab at end I, a driver's cab at end II, a machine room at end I, and a machine room at end II. The four welcome lights are located in the driver's cab at end I, the driver's cab at end II, the machine room at end I, and the machine room at end II, respectively, and are used to illuminate the driver's cab at end I, the driver's cab at end II, the machine room at end I, and the machine room at end II, respectively. The door touch switches in the same workroom correspond to the welcome lights in that workroom. When any door touch switch is in the closed state, all welcome lights are illuminated; alternatively, when any door touch switch is in the closed state, all welcome lights corresponding to that door touch switch are illuminated. If the two doors of the driver's cab at end I correspond to door touch switches K1 and K2 respectively, the two doors of the driver's cab at end II correspond to door touch switches K3 and K4 respectively, the machine room at end I corresponds to door touch switch K5, the machine room at end II corresponds to door touch switch K6, the welcome light in the driver's cab at end I is LED1, the welcome light in the driver's cab at end II is LED2, the welcome light in the machine room at end I is LED3, and the welcome light in the machine room at end II is LED4, then the door touch switches K1 and K2 correspond to the welcome light LED1, the door touch switches K3 and K4 correspond to the welcome light LED2, the door touch switch K5 corresponds to the welcome light LED3, and the door touch switch K6 corresponds to the welcome light LED4. For example, when the door touch switch at any door gap of the driver's cab at end I (i.e., any one of the door touch switches K1 or K2 is in the closed state) is in the closed state, the welcome light LED1 in the driver's cab at end I is illuminated.

[0039] In this embodiment, the operating voltage of each welcome light is DC12V, the type is LED light, and the power is 10W.

[0040] The control module is used to control the on and off of each welcome light according to the status signal of the vehicle's low-voltage power supply and the status signal of each door touch switch. In this embodiment, the operating voltage of the control module is DC12V, which is powered by the backup energy storage module.

[0041] like Figure 2 As shown, an embodiment of the present invention provides a control method for the above-mentioned boarding welcome lighting system, comprising the following steps:

[0042] Step 1: The conversion power module detects the status of the vehicle low-voltage power supply according to the output voltage of the vehicle low-voltage power supply, and sends a status signal of the vehicle low-voltage power supply to the control module. When the vehicle low-voltage power supply is in a working state, the conversion power module converts the output voltage of the vehicle low-voltage power supply into the rated voltage of the backup energy storage module to charge the backup energy storage module.

[0043] Step 2: Each door touch switch detects the door status of each working room and sends the door status signal of each working room to the control module;

[0044] Step 3: The control module controls the on and off of each welcome light according to the status signal of the vehicle's low-voltage power supply and the status signal of each door touch switch (or the door status signal detected by each door touch switch).

[0045] In step 1, when the output voltage of the vehicle's low-voltage power supply is less than the set voltage, the vehicle's low-voltage power supply is in an inoperative state. When the output voltage of the vehicle's low-voltage power supply is greater than or equal to the set voltage, the vehicle's low-voltage power supply is in an operational state. In this embodiment, when the normal output voltage of the vehicle's low-voltage power supply is DC110V, the set voltage is 77V.

[0046] In step 3, the on and off of each welcome light is controlled according to the status signal of the vehicle's low-voltage power supply and the status signal of each door touch switch, which specifically includes:

[0047] When the vehicle's low-voltage power supply is in working condition, the conversion power supply module converts the output voltage of the vehicle's low-voltage power supply into the rated voltage of the backup energy storage module, and then charges the backup energy storage module to ensure the power demand when the boarding welcome lighting system is working, thereby controlling each welcome light to be in the off state.

[0048] When the vehicle's low-voltage power supply is not in operation and all door touch switches are in the open state, the doors of each studio are in the closed state and there is no lighting demand, so the welcome lights are controlled to be off.

[0049] When the vehicle's low-voltage power supply is in a non-working state and any door touch switch is in a closed state, the door of the studio corresponding to the door touch switch is in an open state and there is a lighting demand, so all the welcome lights are controlled to be in a lit state; or, when the vehicle's low-voltage power supply is in a non-working state and any door touch switch is in a closed state, the welcome light corresponding to the door touch switch is controlled to be in a lit state, and the welcome lights in other studios remain in an off state to save energy.

[0050] For example, when the vehicle's low-voltage power supply is in a non-working state and any door contact switch of the driver's cab at end I is in a closed state, the door of the driver's cab at end I is opened, and all welcome lights are controlled to be in a lit state or the welcome lights in the driver's cab at end I are controlled to be in a lit state.

[0051] In a specific embodiment of the present invention, when the welcome light is in the lighting state, a delay of 5 minutes is made and the welcome light is controlled to be in the extinguishing state to save energy.

[0052] The above disclosure is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or modifications within the technical scope disclosed in the present invention, and they should all be covered by the scope of protection of the present invention.
