Description

Technical Field

[0001] This utility model relates to a lighting circuit, and more particularly to a multi-lighting mode control circuit. Background Technology

[0002] The primary function of a hydropower station is power generation. In addition, it also has comprehensive benefits such as flood control, silt retention, and improvement of upstream navigation conditions.

[0003] The main large equipment of a hydropower station (such as generator sets) are located in an underground powerhouse. A large number of lighting fixtures need to be installed in the powerhouse to ensure the lighting needs of the powerhouse, thereby ensuring the normal operation of power production.

[0004] Early hydroelectric power stations were equipped with traditional full-power lighting fixtures, meaning their operating power was not adjustable, and the lights in different sub-areas were switched on and off synchronously. For example, the lights in the GIS room were either all on or all off, failing to meet the concept of green lighting. Even after some lights were replaced with energy-saving LED lights, the problem of synchronous switching remained unresolved. At night, when high illumination is not required, not all lights need to operate at full power, resulting in significant energy waste in the current hydroelectric power station lighting system. Furthermore, prolonged operation accelerates the aging of the lighting fixtures, affecting their lifespan and causing them to extinguish unexpectedly, posing a safety hazard to operations in the production area. Utility Model Content

[0005] The purpose of this invention is to provide a multi-lighting mode control circuit to address the aforementioned problems, thereby providing a basic circuit for solving the energy waste problem of current hydropower station lighting equipment.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A multi-lighting mode control circuit includes multiple control modules. The second signal terminal of each control module is connected in series with the first signal terminal of the next control module via a protocol gateway. The first signal terminal of the first control module is connected to a controller, and the second signal terminal of the last control module is connected to a sensor probe via the protocol gateway. Each control module draws power from a bus cable of a distribution box. The control module is a dimming control module or a switching control module, and at least one control module is a dimming control module. At least one switching output terminal of the dimming control module is used to connect an adjustable power lamp.

[0008] Furthermore, at least one set of control modules has a bus power module connected to its module power supply terminal; the module power supply terminal of the bus power module is connected to the bus cable of the distribution box, and the voltage output terminal of the bus power module is connected to the module power supply terminal of the control module.

[0009] Furthermore, the signal terminal of the bus power module is connected in series between the control module and the protocol gateway.

[0010] Furthermore, at least one set of control modules is connected to a power meter via a bus cable, and the power meter is connected to a protocol gateway to which the control module is connected.

[0011] Furthermore, a control panel is connected to at least one of the protocol gateways.

[0012] Furthermore, the control panel is connected between the last protocol gateway and the sensing probe, and / or between a portion of the intermediate protocol gateway and the first signal terminal of the subsequent control module.

[0013] Furthermore, each of the control modules is housed in a separate distribution box.

[0014] Furthermore, each group of control modules includes at least one sub-control module. When there is more than one sub-control module, the power supply terminals of all the included sub-control modules are connected in parallel, and the second signal terminal of the previous sub-control module is connected in series with the first signal terminal of the next sub-control module.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This application provides a basic circuit that can configure the working mode. After the circuit of this application is laid out, the user can use the controller to send the configured working mode to each control module according to his own needs. When the control panel receives the corresponding trigger command or the sensor probe detects the corresponding sensing data, the controller is triggered to switch the working mode, so that the working mode of the lamp is adapted to the actual needs, avoiding or minimizing energy waste.

[0017] 2. This application can be expanded in multiple levels. It only requires connecting the control module and the protocol gateway in the same way. The expansion workload is small and the expansion operation is convenient.

[0018] 3. This application separately calculates the energy consumption of different distribution boxes (i.e., the loads of different groups of control modules), providing strong data support for the configuration of working modes and facilitating the optimization and improvement of working modes.

[0020] The markings in the diagram are as follows: 1 is the controller, 2 is the 4-way switch control module, 3 is the protocol gateway, 4 is the bus power module, 5 is the 485 meter, 6 is the distribution box, 7 is the sub-distribution box, 8 is the control panel, and 9 is the sensor probe. Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To address the energy-saving lighting needs of large-scale lighting venues such as hydropower stations, this application provides a multi-lighting mode control circuit. The aim is to provide a basic circuit that allows users to configure corresponding lighting modes according to their own needs and send them to each group of control modules. When the sensor detects the corresponding triggering condition, or when the control panel actively triggers the corresponding triggering condition, the circuit automatically switches according to the configured lighting mode, thereby avoiding long-term full-power lighting and achieving the purpose of energy saving.

[0024] The multi-lighting mode control circuit provided in this application includes multiple control modules 2, typically one control module 2 for each lighting room (a lighting area contains multiple lighting rooms). The second signal terminal of each control module 2 is connected in series with the first signal terminal of the next control module 2 via a protocol gateway 3. The first signal terminal of the first control module 2 is connected to the controller 1, and the second signal terminal of the last control module 2 is connected to a sensor probe via the protocol gateway 3. In this way, the controller 1 can send the configured lighting modes to each control module 2 for mode configuration, and the signals detected by the sensor probes can also be transmitted to each control module 2 for mode triggering. The controller 1 can be a computer, the control modules 2 can be common programmable devices such as PLCs and MCUs, and the protocol gateway can be an industrial-grade protocol gateway; these devices are all readily available for purchase and use.

[0025] Each control module 2 draws power from the bus cable of a distribution box 6. The power drawn by the control module 2 from the bus cable consists of two parts: one part is the operating power required for its own operation, and the other part is the enabling power for the load. Therefore, for the former, the module power supply terminal of each control module 2 draws power from the bus cable, and for the latter, the voltage input terminal of each control module 2 draws power from the bus cable.

[0026] Furthermore, considering the operating voltage of the selected control module 2, in some alternative embodiments, for some or all of the control modules 2, a bus power module 4 is connected to the module power supply terminal of the control module 2. The module power supply terminal of the bus power module 4 is connected to the bus cable of the distribution box 6, and the voltage output terminal of the bus power module 4 is connected to the module power supply terminal of the control module 2. The bus power module 4 can be an existing power module, which is essentially a transformer, used to step down the voltage of the bus cable of the distribution box 6 to the operating voltage of the control module 2.

[0027] As mentioned earlier, each lighting room is usually equipped with a set of control modules 2, and each lighting room is designed with a distribution box 6. Therefore, there is usually a one-to-one correspondence between each set of control modules 2 and distribution box 6, and the control modules 2 can obtain power from the nearest available source.

[0028] Alternatively, as an optional implementation, each group of control modules 2 can be housed in a separate distribution box 7, with a one-to-one correspondence between the distribution box 6 and the distribution box 7, and one distribution box 6 supplying power to one distribution box 7. Then, a bus power module 4 can be installed in each of the required distribution boxes 7, and a protocol gateway 3 can be installed in each distribution box 7 to facilitate signal transmission between the control modules 2 in that distribution box 7 and the control modules 2 in other distribution boxes 7. Furthermore, depending on the selection, in some optional implementations, the signal terminals of the bus power module 4 are connected in series between the control module 2 and the protocol gateway 3; that is, one signal terminal of the bus power module 4 is connected to the second signal terminal of the control module 2, and the other signal terminal of the bus power module 4 is connected to the protocol gateway 3.

[0029] Different lighting rooms have different requirements for the number of lamps, and it may not be possible to find a control module 2 on the market with a number of switching output terminals that exactly matches the required number of lamps. Considering this, each lighting room can achieve the control of the required lamps by combining multiple sub-control modules 2. Therefore, in some optional embodiments, each group of control modules 2 includes at least one sub-control module 2. When there is more than one sub-control module 2, the module power supply terminals of all included sub-control modules 2 are connected in parallel, and the second signal terminal of the previous sub-control module 2 is connected in series with the first signal terminal of the next sub-control module 2.

[0030] Control module 2 is a dimming control module or a switch control module, and at least one set of control modules 2 (at least one sub-control module) is a dimming control module. At least one switch output terminal of the dimming control module is used to connect to an adjustable power luminaire. An adjustable power luminaire is one whose operating power is adjustable, for example, it can operate at 50% or 80% of its rated power to adjust the brightness. In contrast, a non-adjustable power luminaire is a full-power luminaire, which only has one operating mode: 100% rated power.

[0031] In addition, to facilitate connection to the actual lighting needs of different lighting rooms and for purposes such as lighting mode optimization, in some optional embodiments, at least one group of control modules 2 is connected to a power meter 5 via its bus cable. The power meter 5 is connected to the protocol gateway 3 to which the control module 2 is connected. The power meter 5 records the power consumption of the load of the control module 2 group and uploads it to the controller 1 via the protocol gateway 3 for aggregation. The controller 1 can then obtain the power consumption of different lighting rooms and optimize the operating mode of the different control modules 2 accordingly. Typically, a power meter 5 is connected to the bus cable to which each group of control modules 2 is connected.

[0032] In addition to triggering lighting mode switching via sensor probes, active triggering of lighting mode switching can also be considered. In some optional implementations, a control panel is connected to at least one protocol gateway 3. By operating the control panel, the triggered lighting mode can be transmitted to each group of control modules 2 along the entire signal link, thereby actively triggering the switching of lighting modes.

[0033] In some feasible implementations, the control panel is connected between the last protocol gateway 3 and the sensor, and / or between a portion of the intermediate protocol gateway 3 and the first signal terminal of the next control module 2. For example, a control panel is connected after each protocol gateway 3 (i.e., between the protocol gateway 3 in the previous distribution box 7 and the control module 2 in the next distribution box 7, or between the last distribution box 7 and the sensor), so that the switching of lighting modes can be actively triggered in each lighting room.

[0034] like Figure 1 The diagram illustrates an example of a multi-lighting mode control circuit provided in this application embodiment. This circuit includes multiple control modules; here, all control modules 2 within a single distribution box are referred to as a single control module. Typically, a control module has four switching output terminals. Depending on the number of lamps to be controlled by the distribution box 7, a distribution box 7 may include at least one control module 2. Each distribution box 7 is equipped with a protocol gateway 3 for signal transmission between the control module 2 within that distribution box 7 and the control modules 2 of other distribution boxes 7.

[0035] like Figure 1 As shown, the first signal terminal of the first control module 2 of the first distribution box 7 is connected to a control signal from the controller 1. When the circuit of this application is specifically applied, this control signal typically includes multiple lighting modes configured for each control module, such as which lights are turned on in which lighting mode, the start time and triggering conditions of each lighting mode, etc. This data is configured when applying the circuit of this application and is not within the scope of this application.

[0036] The first distribution box 7 contains two 4-way switch control modules. After the first signal terminal of the first 4-way switch control module receives a control signal, it is transmitted through its second signal terminal to the first signal terminal of the other 4-way switch control module. The second signal terminal of the other 4-way switch control module then transmits the control signal to a signal terminal of the bus power module 4. The other signal terminal of the bus power module 4 continues to transmit the control signal to a signal terminal of the protocol gateway 3. The protocol gateway 3 then transmits the control signal through other signal terminals to the first signal terminal of the first 4-way switch control module in the next distribution box 7, and so on. The second signal terminal of the protocol gateway 3 in the last distribution box is connected to a control panel 8, which is connected to sensor probes 9. Sensor probes 9 are arranged in each lighting area to sense whether there is human activity in the lighting area, or to sense the brightness of the lighting room, etc. The bus cables in each distribution box 7 are grounded through switch k6.

[0037] Control panel 8 is used to receive commands input by the user. Therefore, in order to facilitate operation and avoid the limitation of having only one operation point, control panel 8 can also be set up in other places, such as between two distribution boxes 7 (i.e., between a signal terminal of the protocol gateway 3 of the previous distribution box 7 and the first signal terminal of the first 4-way switch control module of the next distribution box 7).

[0038] It should be noted that although the devices mentioned above are described as signal terminals, first signal terminals, or second signal terminals, signals can actually be transmitted bidirectionally.

[0039] Each distribution box 7 draws power from the nearest distribution box 6 of the hydropower station. Typically, each lighting room is planned to have one distribution box 6, so the distribution box 7 configured for that lighting room can draw power from the distribution box 6 of that lighting room.

[0040] Taking the first distribution box 7 as an example, the power supply introduced from the distribution box 6 is connected via a bus cable to the voltage input terminals of the two 4-way switch control modules (i.e., the ports corresponding to switches k1, k2, k3, and k4 in the diagram). Additionally, it is connected to the module power supply terminal of the bus power module 4 (i.e., the port corresponding to switch k5 in the diagram; the control module obtains its operating power from the bus cable through the power line corresponding to switch k5). The voltage output terminal of the bus power module 4 is connected to the module power supply terminals of the two 4-way switch control modules. Corresponding full-power lighting fixtures are connected to some or all of the switching output terminals of the two 4-way switch control modules. In some replacement methods, some 4-way switch control modules are replaced with dimming control modules; in this case, adjustable-power lighting fixtures are connected to the switching output terminals of the dimming control modules.

[0041] In the second distribution box 7, the bus power module 4 is omitted, and the bus cable is directly connected to the module power supply terminals of the two 4-way switch control modules. The second signal terminal of the second 4-way switch control module is directly connected to one signal terminal of the protocol gateway 3.

[0042] Additionally, a 485 meter (i.e., power meter 5) is connected to the second distribution box 7 to record the power consumption of that distribution box. The 485 meter is connected to the bus cable leading from the distribution box 6, and is connected to a signal terminal of the protocol gateway 3 inside the distribution box 7 to report the recorded power consumption.

[0043] The last distribution box 7 contains only one 4-way switch control module and one protocol gateway 3, and is also connected to a 485 meter. One signal terminal of the protocol gateway 3 in distribution box 7 is connected to a control panel 8, which is connected to a sensor 9. By operating the control panel 8, corresponding instructions can be generated and transmitted to each control module 2, thereby triggering the corresponding lighting mode. For example, inputting the number 1 will trigger each control module 2 to execute lighting mode one. Similarly, after detecting the corresponding environmental data, the sensor 9 can also trigger each control module 2 to execute the corresponding lighting mode. For example, if someone enters, it will trigger each control module 2 to turn on all the lights.

[0044] like Figure 1 As shown, a control panel 8 is also connected in series on the second signal terminal of the protocol gateway 3 of the second distribution box 7 to provide another operation point where commands can be input.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
