DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0019] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0020] Unless otherwise defined, all scientific and technical terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention relates. Table 1 below is an explanation of the technical terms and their Chinese meanings in the present invention.

[0021] Table 1

[0022] There are still many problems with the current vehicle lighting system. For example, the driver's cab lighting and passenger compartment lighting are completely independent and cannot be controlled synchronously. When the train is in the active and dormant states, the passenger compartment lighting power supply needs to be controlled by two sets of contactors respectively, resulting in a large number of contactors and a complex system. Most lighting control systems lack automatic dimming function, and the few systems with dimming function only support local adjustment of the equipment and cannot achieve centralized control. The system generally does not support remote control. In addition, when the train switches from the active state to the dormant state, the delayed power supply function cannot be achieved.

[0023] Figure 1 This is a passenger compartment lighting control method in the prior art, which sets two SLS switches and SELS, sets two power supply busbars, a normal busbar and a permanent busbar, and two contactors SLC and SAELC. However, setting two SLS switches, two busbars and two contactors to control the lighting system when the battery is in use and not in use makes the circuit complex and the cost high, and the solution does not support remote control function, and does not solve the above defects.

[0024] In order to solve the above defects, the first aspect of the embodiment of the present invention provides a lighting control circuit for an unmanned subway vehicle. Figure 2 As shown, the unmanned subway vehicle lighting control circuit includes: Train power supply bus 1; SLS control switch 2, connected to the train power supply bus 1; CLS control switch 3, connected to the train power supply bus 1; The CLC contactor 4 is connected to the SLS control switch 2, the CLS control switch 3 and the TCMS system 5 respectively, and is configured as follows: In response to detecting that the SLS control switch 2 and / or the CLS control switch 3 are placed in the first control position, or in response to receiving a lighting activation instruction sent by the TCMS system 5, the driver's cab lighting system is activated by electricity; In response to detecting that the SLS control switch 2 and / or the CLS control switch 3 is placed in the second control position, or in response to receiving a lighting shutoff command sent by the TCMS system 5, the power is cut off and the driver's cab lighting system is turned off.

[0025] In some embodiments, Figure 3 As shown, the unmanned subway vehicle lighting control circuit of the present invention is connected to the driver's cab lighting system and the passenger compartment lighting system respectively. The train power supply bus is a DC110V permanent power supply bus, that is, the power supply of the unmanned subway vehicle lighting control circuit is supplied by the vehicle DC110V permanent power supply bus. The vehicle is provided with a three-position self-reset CLS control switch and an SLS control switch, which are respectively "closed", "0" and "open". Putting the switch in the "closed" position indicates that the circuit is connected, and putting the switch in the "open" position indicates that the circuit is disconnected. The "0" position indicates the initial or default state of the switch, and the circuit is not connected at this time. Among them, the first control position is the "closed" position, and the second control position is the "open" position.

[0026] In some embodiments, the driverless subway vehicle includes two lead cars with driver cabs, and a plurality of intermediate cars between the two driver cabs are passenger cabs. Figure 4 As shown, each cab lighting system is equipped with two CLM power modules, such as CLM1 and CLM2, which are responsible for the load of the cab light strip. Each CLM power module is connected to a CLC contactor and is controlled by the corresponding CLC contactor for power supply. The two CLM power modules are interconnected through a backup interconnection line. When the output of one of the CLM power modules (such as CLM1) fails and cannot provide drive for the light strip, the other CLM power module (such as CLM2) will replace the faulty CLM power module (such as CLM1) to output power to provide drive for the light strip connected to the faulty CLM power module (such as CLM1). The cab lighting light strip includes CL1 and CL2.

[0027] In some embodiments, the driver's cab lighting system can be remotely controlled through the TCMS system, or can be individually controlled through the CLS control switch. In addition, when the passenger compartment lighting is turned on or off, the driver's cab lighting is also turned on or off, that is, when the SLS control switch is in the first control position, the driver's cab lighting system and the passenger compartment lighting system are simultaneously controlled to start, and when the SLS control switch is in the second control position, the driver's cab lighting system and the passenger compartment lighting system are simultaneously controlled to shut down. In one example, the control conditions of the driver's cab lighting system include: (1) The CLS control switch is set to the "closed" position; (2) The TCMS system outputs the lighting input command; (3) The SLS control switch is set to the “closed” position; (4) Set the CLS control switch to the “off” position; (5) The TCMS system outputs a lighting shut-off command; (6) Set the SLS control switch to the “off” position.

[0028] When the control conditions of the cab lighting system meet any one of the above (1), (2) and (3), each CLC contactor in the cab lighting system is energized and activated, and its contactor closes to assist in forming a self-locking circuit, thereby supplying power to CLM1 and CLM2 respectively. CLM1 and CLM2 provide drive to the light strips CL1 and CL2 connected to them respectively to light them up, completing the startup of the cab lighting system. When the control conditions of the cab lighting system meet any one of the above (4), (5) and (6), the CLR (cab lighting relay) relay in the cab lighting system is energized and activated, and its normally closed contactor opens, cutting off the self-locking circuit of each CLC contactor, causing each CLC contactor to lose power and disconnect the contactor, CLM1 and CLM2 lose power, and the light strips CL1 and CL2 go out, completing the shutdown of the cab lighting system. Figure 5 and 6 The control of the CLC contactor is realized by setting FCDT between the SLS control switch and the CLS control switch, so that the driver's cab lighting system can be turned on and off independently through the CLS control switch, or can be turned on and off synchronously with the passenger compartment lighting system.

[0029] The unmanned subway vehicle lighting control circuit of the present invention realizes the control of the lighting system when the battery is in operation and not in operation through a permanent power supply bus, and does not need to use two sets of contactors for control, thereby reducing the number of lighting control contactors and saving costs. The TCMS system can automatically control the working conditions of the subway vehicle to meet the control requirements of the unmanned vehicle and realize remote control of the lighting system, and can independently control the driver's cab lighting to be turned off through an independent CLS control switch, and can also realize synchronous control of the passenger compartment lighting and the driver's cab lighting through an independent SLS control switch. Compared with the existing lighting system control circuit, the control logic of the circuit of the present invention is more flexible and energy-saving, can meet the application of various scenarios, create economic benefits, bring market value, and actively respond to the new development concept of reducing carbon emissions and promoting green and sustainable development.

[0030] In some embodiments, a CLR relay is also included, which is respectively connected to the CLS control switch, the SLS control switch, the TCMS system and the CLC contactor, and is configured to: in response to detecting that the SLS control switch and / or the CLS control switch is placed in the second control position or in response to receiving a lighting shutdown command sent by the TCMS system, it is powered on and activated, and the normally closed switch of the CLR relay is controlled to be opened to cut off the power to the CLC contactor.

[0031] In some embodiments, an SLC contactor is also included, which is connected to the SLS control switch and the TCMS system respectively, and is configured as follows: in response to detecting that the SLS control switch is in the first control position or in response to receiving a lighting on command sent by the TCMS system, the contactor is powered on and activated to start the passenger compartment lighting system; in response to detecting that the SLS control switch is in the second control position or in response to receiving a lighting off command sent by the TCMS system, the contactor is powered off and deactivated to shut down the passenger compartment lighting system.

[0032] In some embodiments, an SLR relay is also included, which is respectively connected to the SLS control switch, the TCMS system and the SLC contactor, and is configured to: in response to the SLS control switch being placed in the second control position or in response to receiving a lighting shutdown command sent by the TCMS system, be powered on and activated, and control the normally closed switch of the SLR relay to be opened to cut off power to the SLC contactor.

[0033] In some embodiments, Figure 7 As shown in the figure, each passenger compartment is equipped with an SLCU and four SLM power modules, such as SLM1, SLM2, SLM3 and SLM4. All lamps in each passenger compartment are in parallel structure, including passenger compartment lighting strips (such as SL1 and SL2), channel lights (such as GL1 and GL2) and ring lights (such as RL1 and RL2). The lamps on each side are driven by two SLM power modules respectively, so that all light strips can be lit at the same time.

[0034] In some embodiments, every two SLM power modules are responsible for the load work of the lamps on the same side, and are interconnected through a backup interconnection line. When the output of one of the SLM power modules (such as SLM1) fails and cannot provide drive for the lamp, the other SLM power module (such as SLM2) will replace the failed SLM power module (such as SLM1) to output power.

[0035] In some embodiments, the passenger compartment lighting system can be remotely controlled through the TCMS system, or can be individually controlled through the SLS control switch. In one example, the control conditions of the passenger compartment lighting system include: (1) The SLS control switch is set to the “closed” position; (2) The TCMS system outputs the lighting input command; (3) The SLS control switch is set to the “off” position; (4) The TCMS system outputs a lighting shut-off command.

[0036] When the control conditions of the passenger compartment lighting system meet any one of the above (1) and (2), each SLC contactor in the passenger compartment lighting system is energized and activated, and its contact closure assists in forming a self-locking circuit, thereby supplying power to SLM1~4 respectively. SLM1~4 respectively provide drive to the light strips CL1~2, ​​ring lights RL1~2 and through-channel lights GL1~2 connected to them to light them up, completing the startup of the passenger compartment lighting system. When the control conditions of the passenger compartment lighting system meet any one of the above (3) and (4), the SLR relay in the passenger compartment lighting system is energized and activated, and its normally closed contact is disconnected, cutting off the self-locking circuit of each SLC contactor, causing each SLC contactor to lose power and disconnect the contact, SLM1~4 loses power, and the light strips CL1~2, ​​ring lights RL1~2 and through-channel lights GL1~2 are extinguished, completing the shutdown of the passenger compartment lighting system. Figure 5 and 8 shown.

[0037] The unmanned subway vehicle lighting control circuit of the present invention realizes the control of the lighting system when the battery is in use and not in use based on a permanent power supply bus, reduces the number of lighting control contactors, saves costs, and realizes the synchronous control of the passenger compartment lighting and the driver's compartment lighting by designing an independent SLS control switch, making the control logic more flexible.

[0038] In some embodiments, an LDR time delay relay is further included, which is connected to the CLR relay and the SLR relay respectively, and is configured to: in response to receiving a sleep instruction, be powered on and activated, and start timing; monitor whether the timing reaches a preset time; in response to the timing reaching the preset time, control the normally open switch of the LDR time delay relay to close, so as to respectively power on the CLR relay and the SLR relay.

[0039] In some embodiments, an LSR sleep relay is further included, connected to the LDR time delay relay, and configured to: in response to receiving a sleep instruction, control a normally open switch of the LSR sleep relay to close, so as to supply power to the LDR time delay relay.

[0040] In some embodiments, a delay circuit is set using an LRD time delay relay and an LSR sleep relay, and the delay time can be set according to the actual application situation, for example, set to 1 minute. Among them, the LRD time delay relay is an energized delay relay. When the subway vehicle is dormant, a sleep instruction will be sent to the LRD time delay relay and the LSR sleep relay, so that the LRD time delay relay and the LSR sleep relay are energized and activated. Specifically, after the LSR sleep relay receives the sleep instruction and is energized and activated, its normally open contact is closed to form a self-locking circuit to charge the LRD time delay relay, and the LRD time delay relay starts timing after being energized and activated. When the LRD delay relay reaches 1 minute, its normally open contact closes, the SLR relay and the CLR relay are energized and activated, and the normally closed contact is disconnected, so that the self-locking circuit of the CLC contactor and the self-locking circuit of the SLC contactor are cut off respectively, so that the CLC contactor and the SLC contactor lose power and disconnect the contact, thereby causing the CLM1~2 power module and the SLM1~4 power module to lose power, and the light strips CL1~2, ​​light strips SL1~2, ​​through-channel lights GL1~2 and ring lights RL1~2 are extinguished. Figure 5 , Figure 6 and Figure 8 shown.

[0041] The unmanned subway vehicle lighting control circuit of the present invention realizes the delayed power supply function from the activated state to the dormant state through the time delay relay and the dormant relay, so that when the subway vehicle is dormant, the passenger compartment lighting system and the driver's compartment lighting system can still maintain lighting for 1 minute, and automatically turn off the lighting after 1 minute; at the same time, after the subway vehicle is dormant, the passenger compartment lighting system and the driver's compartment lighting system can still be controlled to be turned on or off respectively through the SLS control switch or the CLS control switch, thereby more effectively meeting the control requirements of the unmanned subway vehicle.

[0042] In some embodiments, it also includes a plurality of CLM power modules and a plurality of SLM power modules, each CLM power module is respectively connected to a CLC contactor, in response to the connected CLC contactor being powered on and activated, the CLM power module outputs power to the connected driver's cab lighting strip to start the driver's cab lighting system; in response to the connected CLC contactor being powered off and inactivated, the CLM power module stops outputting power to the connected driver's cab lighting strip to shut down the driver's cab lighting system; each SLM power module is respectively connected to an SLC contactor, in response to the connected SLC contactor being powered on and activated, the CLM power module outputs power to the connected passenger compartment lighting strip to start the passenger compartment lighting system; in response to the connected SLC contactor being powered off and inactivated, the CLM power module stops outputting power to the connected passenger compartment lighting strip to shut down the passenger compartment lighting system.

[0043] In some embodiments, a plurality of backup interconnect lines are further included, which are respectively connected between two CLM power modules or between two SLM power modules, and are configured as follows: in response to detecting that the power output of one of the connected CLM power modules fails, the output power of the other connected CLM power module is transmitted to the driver's cab lighting strip connected to the failed CLM power module; in response to detecting that the power output of one of the connected SLM power modules fails, the output power of the other connected SLM power module is transmitted to the passenger compartment lighting strip connected to the failed SLM power module.

[0044] The unmanned subway vehicle lighting control circuit of the present invention can effectively utilize circuit design to realize the electric energy utilization of the subway vehicle, and improve the redundancy and flexibility of each lighting system and the emergency response capability in case of failure.

[0045] In some embodiments, a dimming controller (i.e., SLCU) and several light sensors are interconnected, and the dimming controller is connected to all CLM power modules and all SLM power modules, and is used to output a dimming signal based on the light sensor to adjust the output power of all CLM power modules and all SLM power modules.

[0046] In some embodiments, an LMS lighting mode switch is also included, which is connected to the guest room lighting dimming controller and is configured as follows: in response to detecting that the LMS lighting mode switch is in the automatic position, the guest room lighting dimming controller is controlled to output a dimming signal according to the indication of the light sensor; in response to detecting that the LMS lighting mode switch is in the fixed position, the guest room lighting dimming controller is controlled to output a dimming signal according to a preset indication.

[0047] In some embodiments, Figure 7 As shown, the dimming controller is arranged in the passenger compartment lighting system, which can control the dimming functions of the driver's cab lighting system and the passenger compartment lighting system at the same time by outputting PWM signals. The dimming controller can realize emergency lighting function and automatic dimming function. Specifically, the auxiliary system provides the dimming controller with a normal working signal of the subway vehicle charger. When the dimming controller does not receive the normal working signal, the dimming signal is changed and output to the CLM1~2 power modules of the driver's cab lighting system and the SLM1~4 power modules of the passenger compartment lighting system to reduce the output power of each power module, so that the illumination of the light strips CL1~2, ​​light strips SL1~2, ​​channel lights GL1~2 and ring lights RL1~2 is reduced, thereby completing the emergency lighting function. As shown Figure 7As shown, each passenger compartment lighting system is provided with two light sensors. When the two light sensors detect changes in the illumination in the passenger compartment, the illumination changes are fed back to the dimming controller. The dimming controller outputs dimming signals to the CLM1~2 power modules of the driver's cab lighting system and the SLM1~4 power modules of the passenger compartment lighting system to adjust the output power of each power module, so that the illumination of the light strips CL1~2, ​​light strips SL1~2, ​​through-channel lights GL1~2 and ring lights RL1~2 changes, thereby completing the automatic dimming function, as shown in FIG. Fig. 9 shown.

[0048] In some embodiments, the passenger room lighting system is further provided with an LMS lighting mode switch, which is a two-position non-self-resetting lighting mode switch, and the two positions include an "automatic" position and a "fixed" position. When the LMS lighting mode switch is in the "automatic" position, the dimming controller enables the automatic dimming mode, that is, outputs a dimming signal to control the illumination of the lamp according to the illumination change fed back by the light sensor. When the LMS lighting mode switch is in the "fixed" position, the dimming controller turns off the automatic dimming module, that is, it is not affected by the light sensor.

[0049] The unmanned subway vehicle lighting control circuit of the present invention can automatically adjust the brightness of the vehicle lighting by the dimming controller when the vehicle charger is working normally, and can control whether to enable the automatic dimming function through the LMS lighting mode switch. When the vehicle charger is not working normally, the dimming controller turns on the emergency lighting, which effectively meets the application of various scenarios, is conducive to reducing carbon emissions, promoting green and sustainable development, and provides comfortable and convenient services for drivers and passengers.
