Description

Technical Field

[0001] The present invention relates to the field of lighting, and in particular to a multi-mode lighting control system for a hydropower station and an operating method thereof. Background Art

[0002] Hydropower stations are mainly used for power generation, and also have comprehensive benefits such as flood control, sand retention and improvement of upstream navigation conditions. They can also provide cascade compensation for downstream power stations.

[0003] The generators of hydropower stations are all located in underground workshops. In order to ensure the normal development of power production, a large number of lighting facilities are needed to ensure the lighting needs in the workshops. The hydropower stations that have been built, especially those built in the early stage, did not consider the needs of green lighting during construction. The lighting lamps are extremely powerful. Even if some lamps are replaced with LED energy-saving lamps in the later stage, the lighting mode has always been in long-brightness mode, that is, once turned on, it will work at full power in any case. This will cause a huge waste of energy, accelerate the aging of lighting lamps, affect the life of lighting equipment, and bring hidden dangers to the safety of production area operations.

DETAILED DESCRIPTION

[0034] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0035] Any feature disclosed in this specification (including any additional claims and abstract), unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0036] In response to the serious problem of energy waste caused by the current full-power long-lasting lighting mode adopted by hydropower stations, the embodiment of the present application provides a multi-mode lighting control system for a hydropower station and an operation method thereof, aiming to reduce lighting energy consumption and achieve energy-saving effects.

[0037] The multi-mode lighting control system for a hydropower station provided in an embodiment of the present application includes a central controller 1, which is connected to second-level switches arranged in different areas through first-level switches. Each second-level switch is connected to a local sub-control device to achieve independent control of regional lighting. Each second-level switch is connected to a third-level switch arranged in a different sub-area; each third-level switch is connected to an intelligent gateway 6 arranged in a different lighting room; each intelligent gateway 6 is connected to a group of control modules 7; the control module 7 is connected to a control panel 8 and / or a sensor probe 9. The switch output port of the control module 7 is used to connect a lamp, which is an adjustable power lamp or a full-power lamp.

[0038] The central controller 1 or the local sub-control device is used to configure the lighting mode to the connected control module 7; each control module 7 switches the connected lamp to the corresponding lighting mode based on the configured lighting mode and the signal fed back by the connected control panel 8 or the sensor probe 9.

[0039] As an optional implementation, the first-level switch includes a core switch host and a core switch standby machine, and the central controller 1 is connected to the core switch host and the core switch standby machine respectively. The core switch host and the core switch standby machine are isolated by a horizontal isolation device 11. The second-level switch is connected to the core switch host. When it is necessary to switch to the core switch standby machine, the central controller 1 releases the isolation between the core switch standby machine and the core switch host by the horizontal isolation device 11. Figure 1 As shown, the central controller 1 is equipped with a master / standby 16-port Gigabit industrial-grade network core switch (i.e., the first-level switch). During normal operation, the 16-port Gigabit industrial-grade network core switch host 2 is used (unless there are special circumstances in the following text, the 16-port Gigabit industrial-grade network core switch mentioned refers to the host). In the event of a failure or other emergency, the 16-port Gigabit industrial-grade network core switch standby machine 10 is used instead. A horizontal isolation device 11 is configured between the host and the standby machine to isolate the two switches.

[0040] The 16-port Gigabit industrial-grade network core switch of the central controller 1 is connected to the 24-port Gigabit industrial-grade network core switch 4 (i.e., the second-level switch) in the sub-control cabinets in three different areas, namely the dam area, the left bank area, and the right bank area, through single-mode four-core optical fiber. Local sub-control devices are also provided in the dam area, the left bank area, and the right bank area, collectively referred to as regional-level controllers 3. The regional-level controllers 3 are connected to the 24-port Gigabit industrial-grade network core switch 4 in the area for independent control of the lighting fixtures in the area.

[0041] As an optional implementation, the lighting modes configured by the central controller 1 or the regional controller 3 for the control module include at least three categories: the first lighting mode, the second lighting mode and the third lighting mode; the three lighting modes are respectively for areas with different activity amounts. Among them, the first lighting mode is for areas between the first activity amount and the second activity amount, which are called areas with a small amount of activity; the second lighting mode is for areas with more than the second activity amount, which are called areas with frequent activities; the third lighting mode is for areas with less than the first activity amount, which are called areas with very few activities.

[0042] In some feasible embodiments, the above three types of lighting modes are specifically configured as follows:

[0043] The first type of lighting mode is aimed at areas with a small amount of activity. This type of lighting mode includes: the first maintenance mode, the inspection mode and the night lighting mode.

[0044] Maintenance mode, this mode is turned on when triggered (such as maintenance work). For adjustable power lamps, it works at 100% brightness, and for full power lamps, all are turned on. This working mode can be triggered by the central controller 1 or the control panel 8 of the lighting room being repaired.

[0045] Inspection mode, this mode is automatically turned on in a specific time period (such as 7 am to 9 pm), or is triggered to turn on by the central controller 1 / control panel 8. For adjustable power lamps, they work at 50% brightness, and for full power lamps, they are turned on at intervals. This mode can collect illumination data through the on-site sensor probe 9 for feedback, and automatically adjust the illumination of the lamps in the lighting room to the set value / set interval based on the feedback information. For example, it can be adjusted by increasing or decreasing the brightness of the adjustable power lamps, or by increasing or decreasing the number of full power lamps turned on.

[0046] Night lighting mode, this mode is automatically turned on in a specific time period (such as 9 pm to 7 am the next day), or triggered to turn on by the central controller 1 / control panel 8. For adjustable power lamps, it is sufficient to work at an illumination that meets the needs of surveillance cameras (such as 10% power), and for full-power lamps, it is sufficient to turn on the number of lamps that meet the needs of surveillance cameras. In addition, when the sensor probe 9 senses that someone has entered the lighting room, the lighting mode of the lighting room is automatically switched to the inspection mode, and it is restored to the night lighting mode after sensing that the person has left.

[0047] The second type of lighting mode is for areas with frequent activities. This type of lighting mode includes: the second maintenance mode and the energy-saving lighting mode.

[0048] The second maintenance mode is automatically turned on in a specific time period (such as 7 am to 9 pm), or is triggered to turn on by the central controller 1 / control panel 8. For adjustable power lamps, they work at 100% brightness, and for full power lamps, they are all turned on.

[0049] Energy-saving lighting mode, this mode is automatically turned on in a specific time period (such as 9 pm to 7 am the next day), or triggered to turn on by the central controller 1 / control panel 8. For adjustable power lamps, it is sufficient to work at an illumination that meets the requirements of surveillance cameras (such as 10% power), and for full-power lamps, it is sufficient to turn on the number of lamps that meet the requirements of surveillance cameras. In addition, when the sensor probe 9 senses that someone has entered the lighting room, the lighting mode of the lighting room is automatically switched to the second maintenance mode, and restored to the energy-saving lighting mode after sensing that the person has left.

[0050] The third type of lighting mode is for areas with very little activity. In this type of lighting mode, when the sensor probe 9 reports that someone has entered the lighting room, the adjustable power lamps (usually the areas using the third type of lighting mode do not install adjustable power lamps) operate at 100% brightness, and all full-power lamps are turned on. When no one enters, for example, when the sensor probe 9 reports that there is no activity, all lamps are turned off. The third type of lighting mode can be triggered directly by the control panel 8, that is, all lamps are turned on or off manually; it can also be triggered by the sensor probe 9, that is, all lamps are turned on when a person is sensed, and all lamps are turned off when no person is sensed.

[0051] The 24-port Gigabit industrial-grade network core switch 4 in each area is connected to the access layer switch 5 (i.e., the third-pole switch) of each sub-area through a single-mode optical fiber, and each access layer switch 5 is connected to the intelligent gateway 6 of each lighting room through a network cable, and each intelligent gateway 6 is connected to the corresponding control module 7 through a network cable. The control module 7 under each intelligent gateway 6 is connected to at least one control panel 8, and at least one control panel 8 is connected to a sensing probe 9 for collecting sensing data. For example, the sensing probe is a motion sensing probe for collecting activity (presence or absence), or the sensing probe is a brightness sensing probe for collecting lamp illumination.

[0052] Taking the right bank area as an example, the single-mode four-core optical fiber is connected to the 24-port Gigabit industrial network core switch 4 in the sub-control cabinet in the right bank area. The 24-port Gigabit industrial network core switch 4 is then connected to the access layer switch 5 in the control box (RGIS-VP1) of different sub-areas through single-mode optical fiber. Each control box is equipped with a pigtail tray, a single-mode optical fiber converter and an access layer switch 5. The 24-port Gigabit industrial network core switch 4 is connected to each pigtail tray. The pigtail tray is connected to the single-mode optical fiber converter through a single-mode optical fiber, and the single-mode optical fiber converter is connected to the access layer switch 5 through a network cable. The access layer switch 5 is then connected to the intelligent gateway 6 of different lighting rooms through a network cable. Usually, the control box of a sub-area can be installed in a lighting room of the sub-area to save wiring resources.

[0053] Usually, it is difficult to directly purchase the right number of control modules 7 for the number of lamps required to be installed in a lighting room, so multiple control units are usually combined into a group of control modules 7 for use. For the multiple control units included in the control module 7, adjacent control units are connected in series through a protocol gateway, and the last control module is connected to the control panel 8 and / or the sensor probe 9 through a protocol gateway; each control unit and the protocol gateway connected to the control unit are installed in the same distribution box, and each distribution box draws power from a distribution box.

[0054] Taking a sub-area as an example, the access layer switch 5 is connected to the first intelligent gateway 6 in the sub-area through a network cable, and the intelligent gateway 6 and the access layer switch 5 are installed in the same control box. Figure 2As shown, multiple distribution boxes are installed in the lighting room: RGIS-ZM1, RGIS-ZM2, RGIS-ZM3, RGIS-ZM4, RABN81, RABN80, RABN79, RABE46, RABN78, RABN77, RABN76, RABE45, RABN75, RABN74, RABN73, RABE44, RABN72 and RABN82. The intelligent gateway 6 is connected to a 3-way dimming control module through a control cable, and then connected to the 4-way switch control module in the distribution box RGIS-ZM1 through a bus power module (the 3-way dimming control module and the bus power module are also installed in the control box), and the 4-way switch control module is connected to the 4-way switch control module in the distribution box RGIS-ZM2 through a protocol gateway... The protocol gateway in the distribution box RABN82 is connected to the control panel 8 of the lighting room (such as an intelligent liquid crystal lighting touch panel), and the control panel 8 is connected to the sensor probe 9 in the lighting room. Each switch control module / dimming control module directly draws power from the distribution box of the lighting room, and the switch quantity control port of each switch control module / dimming control module is connected to the corresponding lamp through a copper core cable.

[0055] In addition, in order to understand the power consumption of different sub-areas, it is convenient to plan the lighting mode, such as Figure 2 As shown, a 485 meter (i.e., a power meter) is also installed in some distribution boxes, and the 485 meter is used to record the energy consumption of the corresponding distribution box. The 485 meter is connected to the bus cable of the distribution box corresponding to the distribution box to record the power consumption, and the 485 meter is connected to the protocol gateway of the distribution box to report the recorded power consumption to the central controller 1.

[0056] A control panel 8 is also connected between some of the sub-meters to facilitate multi-point control and avoid operational limitations when only one control panel 8 is provided for a large lighting room.

[0057] like Figure 3 The figure shows the control circuit diagram inside the distribution box RGIS-ZM1. The distribution box RGIS-ZM1 draws power from the distribution box through a copper core cable (specification BV-5*2.5DN25), and is connected to the module power supply end and the 4 voltage input end of the 4-way switch quantity control module therein through a bus cable. The 3-way switch quantity output end (N1, N2, N3 in the figure) of the 4-way switch quantity control module are respectively connected to different full-power lamps, and the remaining switch quantity output end N4 is used as a backup. The signal from the intelligent gateway 6 is connected to the signal input end of the 4-way switch quantity control module, and the 4-way switch quantity control module also transmits the received signal backward through the signal output end, and transmits the signal to the rear-level distribution box after converting it through the protocol gateway. The signal from the induction probe 9 / control panel 8 can also be transmitted in reverse through the signal link.

[0058] In addition, considering that the operating voltage of the control module may not match the bus cable voltage of the distribution box, in some embodiments, one or more control units draw power from the distribution box through a bus power module, and the bus power module converts the voltage output by the distribution box (on the bus cable) into the operating voltage of the control unit.

[0059] Figure 4 The control circuit diagram in the distribution box RABN80 is shown. The distribution box RABN80 also draws power from the distribution box through a copper core cable (specification BV-5*2.5DN25), and is connected to the module power supply end of the bus power module therein and the voltage input ends of each switch control module through a bus cable. The voltage output end of the bus power module is connected to the module power supply end of two 4-way switch control modules respectively. The switch output ends of the two 4-way switch control modules are connected to the corresponding lamps or are idle for standby. The signal from the intelligent gateway 6 is connected to the signal input end of a 4-way switch control module, and the signal output end of the 4-way switch control module is transmitted to the signal input end of another 4-way switch control module, and the signal output end of the other 4-way switch control module is transmitted to the bus power module, and the signal output end of the bus module converts the signal through the protocol gateway and transmits it to the next-level distribution box. The signal from the induction probe 9 / control panel 8 can also be transmitted in reverse through this signal link. The protocol gateway of the last-level distribution box no longer transmits the signal of the intelligent gateway 6 backward.

[0060] The present application also provides a working method of the hydropower station multi-mode lighting control system of the above embodiment, the method comprising:

[0061] Different lighting modes are configured in the central controller 1, and each lighting mode is sent to local sub-control devices in different areas respectively; each local sub-control device configures the received lighting mode to the connected control module.

[0062] Alternatively, different lighting modes are configured in the central controller 1, and each lighting mode is respectively configured to control modules in different areas.

[0063] The first method is that the central controller 1 distributes the lighting mode to different areas, and then the local sub-control device at the regional level configures the lighting mode. The second method is that the central controller 1 directly configures the control modules of different areas. Of course, in both methods, the lighting mode of the connected control module can be updated through the local sub-control device.

[0064] After the lighting mode is configured, the control modules in the lighting rooms of different areas can switch the corresponding lighting mode according to the instructions generated by the control panel 8 or the signals fed back by the sensor probe 9 corresponding to the configured lighting mode.

[0065] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
