Description

Technical Field

[0001] This utility model belongs to the field of intelligent lighting control technology, and specifically relates to an intelligent lighting control system. Background Technology

[0002] With the rapid development of the new energy industry, industrial and commercial energy storage systems and large-scale energy storage systems have emerged.

The current lighting pattern is rather simplistic. Regardless of the ambient light level, the built-in lights activate as soon as the cabinet door is detected as open, without considering actual environmental and lighting needs. This lighting pattern is not conducive to energy conservation and environmental protection. Utility Model Content

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0025] This utility model embodiment provides an intelligent lighting control system; please refer to [link / reference]. Figure 1 The system mainly includes a door opening detection unit, a control loop, and a BMS system. The BMS system is electrically connected to the door opening detection unit, which detects the door opening signal. The BMS system is also electrically connected to the control loop, which has a first control switch and a lighting unit connected in parallel. The first control switch is turned on or off based on light intensity. The BMS system supplies power to the control loop when it receives a door opening signal. The first control switch turns the lighting unit off or on based on the light intensity. The lighting unit emits light when it is on.

[0026] The BMS system is the battery management system integrated into the energy storage cabinet. Based on the BMS system, the intelligent lighting control system of this application is developed. The door opening signal triggers the BMS system to supply power to the lighting control system, realizing the basic conditions for lighting control. The first control switch realizes the lighting requirement based on the light intensity, thereby realizing lighting control management under the dual constraints of door opening and light intensity.

[0027] In this application, the door opening detection unit can be an electronic device such as an angle sensor, encoder, photoelectric switch, or mechanical switch that can be applied to the cabinet door and effectively characterize the degree of opening and closing of the cabinet door. It sends an opening signal to the BMS system. The opening signal can be a continuous detection signal or a state-based trigger signal. For example, taking an angle sensor or encoder as an example, it can characterize the opening degree of the cabinet door. The BMS system judges the received opening degree signal. When the opening degree reaches a preset value, it considers the cabinet door to be open, i.e., an opening signal. After receiving the opening signal, the BMS system supplies power to the control circuit. Taking a photoelectric switch or mechanical switch as an example, when the opening degree of the cabinet door reaches a certain level, the switch closes, thereby conducting the detection circuit between the door opening detection unit and the BMS system, so that the BMS system can receive the opening signal. After receiving the opening signal, the BMS system supplies power to the control circuit.

[0028] In this application, please refer to Figure 1 The control circuit is equipped with a first control switch and a functional module. The functional module can be a lighting unit. The state of the first control switch determines whether the lighting unit emits light.

[0029] For example, the decision factor for the first control switch can be the light intensity. The first control switch can be a phototransistor, the base of which is a photosensitive area. The conduction of the phototransistor is controlled according to the light intensity, so that the lighting unit emits light. When the light intensity is insufficient, the phototransistor is turned off, and the lighting unit emits light.

[0030] It is understandable that the decision factors for the first control switch can also be other factors, which can be adjusted according to the actual needs of the functional module. For example, when the functional module is a temperature control unit, the decision factors can be temperature, humidity, etc., and the first control switch can be a thermal switch, thermistor, etc., which conducts when a certain temperature is reached, so that the temperature control unit works. The temperature control unit can be used to implement cooling function, heating function, ventilation function, etc.

[0031] For ease of control, a second control switch K1 can be configured on the control circuit. The second control switch K1 is a conventional mechanical on / off switch, which can be used for autonomous control by the staff, but its application scenario should be under the condition that the cabinet door is open.

[0032] Of course, in order to meet the operational needs when the cabinet door is closed, the door opening signal or maintenance signal can be imported through external input based on the BMS to trigger the BMS system to supply power to the control circuit, so that the second control switch K1 can effectively operate the lighting unit to emit light and meet the lighting needs of the closed cabinet.

[0033] Furthermore, the operating mode of the cabinet lighting can be set based on the BMS system, so that the BMS system will still provide power to the control loop when the cabinet is closed.

[0034] In the embodiments of this application, the lighting unit includes multiple light-emitting components, and the multiple reflective components can be distributed in different areas within the cabinet. The light-emitting components can be deployed according to actual lighting needs. Specifically, the light-emitting components can be light-emitting diodes and their arrays or other electronic devices capable of emitting light.

[0035] Please see Figure 1 The control loop is represented in the form of a circuit. The BMS system supplies power to the circuit. When the BMS system receives the door opening signal from the door opening detection unit, it supplies power to the circuit, so that the circuit equipped with the lighting unit has the basic conditions to implement lighting.

[0036] In one specific embodiment, the circuit includes electronic components such as a first resistor R1, a phototransistor Q1, a second resistor R2, a transistor QT, a third resistor R3, a fourth resistor R4, a MOSFET, and an illumination unit. Their connection relationships can be found in [reference needed]. Figure 1As shown, the specific configuration is as follows: The first resistor R1 is connected in series between the BMS system and the collector of the phototransistor Q1. The base of the phototransistor Q1 is the photosensitive area, and the emitter of the phototransistor Q1 is electrically connected to the base of the transistor QT. The second resistor R2 is connected in series between the first resistor R1 and the collector of the transistor QT. The emitter of the transistor QT is electrically connected to the gate of the MOSFET. The fourth resistor R4 is connected in series between the first resistor R1 and the drain of the MOSFET. The lighting unit is connected in parallel between the fourth resistor R4 and the source of the MOSFET. The source of the MOSFET is grounded (GND). One end of the third resistor R3 is electrically connected to the gate of the MOSFET, and the other end of the third resistor R3 is grounded (GND).

[0037] Based on the above circuit structure, when the phototransistor Q1 is turned off, the transistor is turned off, the MOS transistor is turned off, the lighting unit is in the conducting state, and it can emit light.

[0038] Based on the above circuit structure, the phototransistor Q1 can be regarded as the first control switch; the first control switch can also be a functional circuit composed of the first resistor R1, the phototransistor Q1, the second resistor R2, the transistor QT, the third resistor R3, the fourth resistor R4, and the MOS transistor. The functional circuit is connected in parallel with the lighting unit. When the functional circuit is off, the lighting unit is turned on and emits light; conversely, when the functional circuit is on, the lighting unit is short-circuited and does not emit light.

[0039] Based on this light-emitting principle, the light-emitting component of the lighting unit can be a light-emitting diode (LED), with multiple LEDs connected in series, such as... Figure 1 Four light-emitting diodes are configured in the circuit: D1, D2, D3, and D4. The four light-emitting diodes are connected in series and in parallel with the first control switch.

[0040] Based on the circuit connection method described above, the BMS system built into the energy storage cabinet can be used for light intensity detection and lighting control of the entire energy storage cabinet.

[0041] When the cabinet door is opened, the BMS system receives the door opening signal and supplies power to the circuit; when the cabinet door is closed, the door opening signal disappears and the BMS system stops supplying power to the circuit.

[0042] With the cabinet door open and sufficient light intensity, phototransistor Q1 turns on. Transistor QT is an NPN type and turns on when the emitter is forward biased. For N-type MOSFETs, Vg > Vs, so the MOSFET turns on.

[0043] When the BMS system receives the door opening signal, if there is no light or the light is very dim, the current of phototransistor Q1 is very small and can be ignored. At this time, phototransistor Q1 is in the off state, transistor QT is in the off state, and MOSFET is not conducting; the lighting component is conducting, that is, the lamp is lit.

[0044] When the BMS system receives the door opening signal, if the light intensity is sufficient, the current of phototransistor Q1 increases, phototransistor Q1 turns on, transistor QT turns on, MOSFET Vg > Vs, MOSFET turns on; the lighting component is turned off, that is, the lamp goes out.

[0045] As a possible embodiment, the circuit may further include a second control switch K1, which is connected in parallel across the collector and emitter of the phototransistor and is built into the interior of the cabinet door.

[0046] For example, the second control switch K1 is normally in the off state, and the control effect is implemented by the phototransistor Q1 alone. When the phototransistor Q1 is faulty, lighting can be temporarily achieved based on the second control switch K1.

[0047] The on / off relationship between the second control switch K1 and the phototransistor Q1 is as follows:

[0048] Firstly, the second control switch is in the normal open state:

[0049] When the phototransistor is turned on, the transistor conducts, the MOSFET conducts, and the lamp goes out.

[0050] When the phototransistor is turned off, the transistor is disconnected, the MOSFET is turned off, and the lamp lights up.

[0051] Secondly, phototransistor Q1 is in a cutoff fault state:

[0052] When the second control switch is closed, the transistor turns on, the MOSFET turns on, and the lamp turns off.

[0053] When the second control switch is turned off, the transistor is cut off, the MOSFET is cut off, and the light turns on.

[0054] Please see Figure 2 With the cabinet door open, the lighting control system of this application controls the lighting based on the ambient light intensity. The ambient light comes from an external light source, and the position of the external light source will affect the position of the light entering the cabinet. The light intensity may vary greatly in different positions inside the cabinet. Therefore, multiple photosensitive zones can be deployed inside the cabinet to ensure that the light intensity in all parts of the cabinet is sufficient, which is conducive to the normal working needs of the staff.

[0055] In a specific embodiment, the detection objects of the door opening detection unit may include a first detection object and a second detection object. The first detection object is located in a first area and the second detection object is located in a second area. Taking a cabinet with double doors as an example, the first area may be the area where the left cabinet door is located and the second area may be the area where the right cabinet door is located. Correspondingly, two first control switches connected in parallel can be configured on the control loop, and the photosensitive areas of the two first control switches are respectively deployed in the first area and the second area.

[0056] For details, please refer to Figure 3 The two first control switches can be a first phototransistor Q1 and a second phototransistor Q2, respectively. The photosensitive area of ​​the first phototransistor Q1 can be deployed in the first area, and the photosensitive area of ​​the second phototransistor Q2 can be deployed in the second area. Specifically, they can be deployed inside the cabinet, rather than on the cabinet door.

[0057] For example, depending on the relative positional relationship between the external light source and the cabinet, the light may be blocked when entering the high-level area. Therefore, in order to ensure that the light intensity in the high-level area meets the standard, the photosensitive area can be deployed inside the cabinet. The low-level area may not be blocked or the blocking range is small, and the photosensitive area can be freely deployed in a suitable location, such as on the cabinet door or inside the cabinet.

[0058] In practice, if only one cabinet door is opened, the light-sensitive area on the other side may be blocked, resulting in sufficient light intensity on one side and insufficient light on the other. In this case, it is preferable to open the cabinet door on the blocked side instead of turning on the lighting unit. Figure 3 In the circuit shown, transistor QT can only be turned off when both first phototransistors Q1 and second phototransistor Q2 are turned off. If only one phototransistor is turned off, transistor QT will still be turned on under the influence of the other phototransistor, and the lighting unit will be in the off state.

[0059] in, Figure 3 In the circuit diagram shown, the second control switch K1 is either not present or is hidden.

[0060] Of course, a split lighting design can be created, where a single photosensitive area controls the corresponding lighting unit on one side, with two identical control loops configured. The photosensitive areas of the two control loops are deployed in separate areas on one side, enabling independent sensing and control of the lighting units on both sides.

[0061] In the embodiments of this application, please refer to Figure 2 The cabinet can be divided into an upper zone and a lower zone, and lighting control can be implemented in the corresponding area according to the light intensity of the upper zone and the lower zone respectively; correspondingly, the control circuit can include two relatively independent branches, which are used to control the lighting needs of the upper zone and the lower zone respectively.

[0062] In one specific embodiment, the door opening detection unit includes an upper zone detection point and a lower zone detection point. The upper zone detection point is located in the upper zone and is used to detect the upper zone door opening signal of the upper zone cabinet door. The lower zone detection point is located in the lower zone and is used to detect the lower zone door opening signal of the lower zone cabinet door. The control loop includes a first branch and a second branch. The BMS system is used to supply power to the first branch when it receives the upper zone door opening signal and to supply power to the second branch when it receives the lower zone door opening signal.

[0063] The first control switch includes a first sensing group and a second sensing group, and the lighting unit includes a first lighting group and a second lighting group. The first sensing group and the first lighting group are configured on the first branch. The photosensitive area of ​​the first sensing group is deployed in the area of ​​the upper region to detect the light intensity of the upper region. The first lighting group is deployed in the area of ​​the upper region to provide lighting to the upper region. The second sensing group and the second lighting group are configured on the second branch. The photosensitive area of ​​the second sensing group is deployed in the area of ​​the upper region to detect the light intensity of the upper region. The second lighting group is deployed in the area of ​​the upper region to provide lighting to the upper region.

[0064] The first lighting group includes multiple upper-area light-emitting components, which are deployed at different positions in the upper area; the second lighting group includes multiple lower-area light-emitting components, which are deployed at different positions in the lower area.

[0065] Please see Figure 4 The first branch corresponds to Figure 4 The upper part of the circuit, the second branch corresponds to Figure 4 The lower half of the circuit. Among them, Figure 4 In the circuit diagram shown, the second control switch K1 is either not present or is hidden.

[0066] Specifically, the first branch consists of a first resistor R1-1, a first phototransistor Q1, a second phototransistor Q2, a second resistor R2-1, a transistor QT-1, a third resistor R3-1, a fourth resistor R4-1, an N1-MOS transistor, and multiple upper-area light-emitting components, wherein the upper-area light-emitting components are specifically light-emitting diodes.

[0067] The first phototransistor Q1 and the second phototransistor Q2 form the first sensing group, and the light-emitting diodes D1, D2, D3, and D4 form the first illumination group. The four light-emitting diodes are deployed at different positions in the upper area; in response to the upper area door opening signal, power is supplied to the first branch.

[0068] Specifically, the second branch consists of a first resistor R1-2, a third phototransistor Q3, a fourth phototransistor Q4, a second resistor R2-2, a transistor QT-2, a third resistor R3-2, a fourth resistor R4-2, an N2-MOS transistor, and multiple lower region light-emitting components, wherein the lower region light-emitting components are specifically light-emitting diodes.

[0069] Among them, the third phototransistor Q3 and the fourth phototransistor Q4 form the second sensing group, and the light-emitting diodes D5, D6, D7, and D8 form the first illumination group. The four light-emitting diodes are deployed at different positions in the lower area; in response to the lower area door opening signal, power is supplied to the second branch.

[0070] It is understandable that the upper area is the high-position area and the lower area is the low-position area. Therefore, the Q1 and Q2 photosensitive areas, which are located in the high-position area, can be placed inside the cabinet and have lower requirements for light intensity; while the Q3 and Q4 photosensitive areas, which are located in the low-position area, can be placed on the cabinet door and have higher requirements for light intensity.

[0071] Of course, the position of the photosensitive area can be adjusted based on the actual position of the external light source, so that the detection effect of the photosensitive area can meet the lighting needs of different areas inside the cabinet, and the built-in lighting system is intelligently controlled.

[0072] As another feasible embodiment, the first control switch can be connected in series with the lighting unit. When the light intensity is sufficient, the first control switch is turned off, causing the lighting unit to turn off and not emit light; when the light intensity is insufficient, the first control switch is turned on, causing the lighting unit to turn on and emit light.

[0073] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0074] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
