The following are detailed descriptions.

[0034] Embodiment 1

[0035] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a control box for controlling multiple loads disclosed in an embodiment of the utility model. Figure 1 The control box for controlling multiple loads described above is applied to lighting equipment, which is not limited in the embodiments of the present invention. Figure 1 As shown, the control box for controlling multiple loads may include:

[0036] Main control chip 10;

[0037] At least two interfaces 20, wherein a first end of each interface 20 is electrically connected to the main control chip 10, and a second end of each interface 20 is used to electrically connect to a load 30;

[0038] A power supply 40, wherein an output end of the power supply 40 is electrically connected to a third end of each interface 20;

[0039] When any target load 30 is connected to a certain interface 20 , the main control chip 10 is used to identify the connected target load 30 and control the power supply 40 to output power to the target load 30 through the interface 20 to which the target load 30 is connected.

[0040] Optionally, the load 30 may be a lamp body, a display, or other power-operated electronic devices, etc.; further, the load 30 may be a freely spliced ​​lamp body, which is not limited in the embodiment of the utility model.

[0041] Optionally, the load 30 may include a lamp body 301 , and the lamp body 301 may include one or more lamp body units, which is not limited in the embodiment of the utility model.

[0042] Optionally, when the actual applied power of the load 30 is less than or equal to its maximum power, the control box can perform safety restrictions to achieve power output operation for more lamps (i.e., loads) under the normal output capacity of a control box, thereby achieving a larger lighting area, which is not limited in the embodiments of the present utility model.

[0043] Optionally, the main control chip 10 can identify the lamp body and the number of lamp body units included in the load 30, calculate the maximum power of the load 30, and then control the power output to the load 30, which is not limited in the embodiment of the utility model.

[0044] Optionally, the main control chip 10 controls the power output to the load 30. When multiple interfaces are connected at the same time, the main control chip 10 can directly output the connected loads corresponding to the multiple interfaces according to the power requirements; when the multiple interfaces are not connected at the same time, the main control chip 10 can flexibly adjust the power output of the connected loads corresponding to the multiple interfaces; further, the power output to the load 30 can be controlled according to the order of the load access interfaces and the total power demand of the load; the power output to the load 30 can also be controlled according to the set priority level of the user who accesses the load and the total power demand of the load; the power output to the load 30 can also be controlled according to the set interface priority and the total power demand of the load; it can also be that under the normal output capacity of the control box, power is output to as many load lamps as possible to achieve a larger lighting area; it can also be that the power output to the load 30 is controlled according to other set conditions, which is not limited in the embodiments of the utility model.

[0045] It can be seen that the implementation Figure 1 The control box described for controlling multiple loads 30 can interact with the target load through the interface to which the target load is connected when any target load is connected to a certain interface, so as to achieve flexible and diverse interface control, meet different interface control requirements, improve the control flexibility and control accuracy of the load power output, and support multiple units to be spliced ​​together for different power requirements. In addition, it can also adapt the spliced ​​load well so that the control box can exert its maximum capacity to meet the power output, and when multiple scenarios or regional load operation are required, there is no need to use multiple control boxes, thereby improving the diversity and flexibility of the load control scenarios.

[0046] In an optional embodiment, if Figure 2 As shown, each interface 20 includes at least a communication sub-interface 201 and a power control sub-interface 202, wherein:

[0047] For any interface 20, the first end of the communication sub-interface 201 in the interface 20 is electrically connected to the main control chip 10, and the second end of the communication sub-interface 201 in the interface 20 is used for communication connection with the load 30; the first end of the power control sub-interface 202 in the interface 20 is electrically connected to the power supply 40, and the second end of the power control sub-interface 202 in the interface 20 is used for power supply connection with the load 30.

[0048] Optionally, the main control chip 10 includes one or more Ctrl terminals; further, the first end of the communication sub-interface 201 in the above-mentioned interface 20 is electrically connected to the main control chip 10. Specifically, the first end of the communication sub-interface 201 in the interface 20 is electrically connected to the Ctrl terminal in the main control chip 10 corresponding to the interface 20; that is, there is a corresponding Ctrl terminal in the main control chip 10 that is electrically connected to the first end of the communication sub-interface 201 in each interface 20, and the embodiment of the utility model is not limited thereto.

[0049] It can be seen that this optional embodiment can realize real-time communication between the main control chip 10 and the main control module 301 of the load through the communication sub-interface 201, which is beneficial to improving the real-time and rationality of communication between the main control chip and the load, and thus is beneficial to improving the accuracy and timeliness of the power control of the load by the main control chip, as well as, realizing power output control between the power supply and the power input module 302 of the load through the power control sub-interface 202, which is beneficial to improving the power input efficiency and convenience between the power supply and the load. In addition, it is also beneficial to improve the independence and pertinence of the communication and power transmission of the load, and thus is beneficial to improving the accuracy of the communication and power transmission of the load.

[0050] In another optional embodiment, Figure 2 As shown, the control box further includes a power switch circuit 50 corresponding to each power control sub-interface 202, wherein:

[0051] For any power control sub-interface 202, the first end of the power switch circuit 50 corresponding to the power control sub-interface 202 is electrically connected to the first end of the power control sub-interface 202, the second end of the power switch circuit 50 corresponding to the power control sub-interface 202 is electrically connected to the main control chip 10, and the third end of the power switch circuit 50 corresponding to the power control sub-interface 202 is electrically connected to the power supply 40.

[0052] Optionally, the power switch circuit 50 is used to implement power switch and current limiting protection functions; further, by way of example: the power switch circuit 50 performs corresponding power on / off operations according to the power switch control signal sent by the main control chip 10, which is not limited in the embodiments of the present utility model.

[0053] Optionally, the main control chip 10, the load 30 and the power switch circuit 50 are illustrated as follows: the main control chip communicates with the load of the target interface in real time through the communication line, the main control chip determines the current required power of the load of the target interface, and when the main control chip detects that the current required power of the load of the target interface is less than the preset maximum power, the main control chip sends an opening signal to the power switch circuit of the target interface, and the power switch circuit of the target interface turns on the power switch after receiving the opening signal, and the power supply supplies power to the load of the target interface according to the current required power; when the main control chip detects that the current required power of the load of the target interface is greater than the preset maximum power, and the power requirement can be met after the power adjustment of the load of the target interface When the power requirement is met, the main control chip sends a power adjustment signal to the load of the target interface through the communication line, and sends an opening signal to the power switch circuit of the target interface. After receiving the opening signal, the power switch circuit of the target interface turns on the power switch, and the power supply supplies power to the load of the target interface according to the current power requirement; when the main control chip detects that the current power requirement of the load of the target interface is greater than the preset maximum power, and the power requirement cannot be met after power adjustment of the load of the target interface, the main control chip sends a closing signal to the power switch circuit of the target interface, and the power switch circuit of the target interface closes the power switch after receiving the closing signal, and the power supply cannot supply power to the load of the target interface, and the embodiments of the utility model are not limited thereto.

[0054] It can be seen that this optional embodiment can realize the power switch control and current limiting protection function for the load through the power switch circuit 50, which is beneficial to improving the controllability and control flexibility of the load power, and is also beneficial to improving the branch operation stability and safety between the power supply and the load.

[0055] In yet another optional embodiment, Figure 2 As shown, the power switch circuit 50 corresponding to each power control sub-interface 202 includes a switch MOS tube 501 corresponding to each power control sub-interface 202, wherein:

[0056] For any power control sub-interface 202, the first end, the second end and the third end of the switch MOS tube 501 corresponding to the power control sub-interface 202 are all electrically connected to the first end of the power control sub-interface 202, the fourth end of the switch MOS tube 501 corresponding to the power control sub-interface 202 is electrically connected to the main control chip 10, and the fifth end of the switch MOS tube 501 corresponding to the power control sub-interface 202 is electrically connected to the power supply 40.

[0057] Optionally, the fourth end of the switch MOS tube 501 corresponding to the power control sub-interface 202 is electrically connected to the main control chip 10. Specifically, the fourth end of the switch MOS tube 501 corresponding to the power control sub-interface 202 is electrically connected to the Ctrl end of the main control chip 10, which is not limited in the embodiment of the utility model.

[0058] It can be seen that this optional embodiment can realize the power switch control and current limiting protection function for the load through the switch MOS tube 501, which is beneficial to improving the controllability and control flexibility of the load power, and is also beneficial to improving the branch operation stability and safety between the power supply and the load.

[0059] In yet another optional embodiment, Figure 2 As shown, the maximum output power of the power supply 40 is less than or equal to the preset power threshold;

[0060] When a load 30 is connected to a certain interface 20 , the output power of the interface 20 is less than or equal to a preset power threshold.

[0061] Optionally, the output power of the interface 20 may be understood as the power output by the power supply 40 through the interface 20 to the load 30 connected to the interface 20 , which is not limited in the embodiment of the present utility model.

[0062] For example, assuming that the preset power threshold is 400W, when a load 30 is connected to a certain interface 20, the main control chip 10 identifies the serial number of the interface 20 and determines the total power demand of the current load. When the total power demand of the load does not exceed 400W, the normal output power is not limited in the embodiment of the utility model.

[0063] It can be seen that this optional embodiment can safely limit the load of the access interface, control the power output of the interface and the load of the access interface, reduce the situation where the load is damaged due to excessive power output to the load through the interface, and to a certain extent improve the operating stability and safety of the load of the access interface.

[0064] In yet another optional embodiment, Figure 2 As shown, when multiple loads 30 are connected to corresponding interfaces 20 respectively, the sum of the output powers of all interfaces 20 to which the loads 30 are connected is less than or equal to the preset power threshold.

[0065] For example, when the main control chip 10 is in standby mode, when multiple loads 30 are connected to the corresponding interfaces 20 respectively, the main control chip 10 first identifies the serial number of the interface, and determines the required load power of the new interface, and adds it to the required load power of the first interface. If the sum of the output powers of all interfaces 20 connected to the load 30 exceeds 400W, the target load is subjected to half-power output processing. If the sum of the output powers still exceeds 400W after the half-power processing, the switch state of the power switch circuit 50 corresponding to the interface is selected to be closed (that is, not powered on) or the power is reduced further until the sum of the output powers of all interfaces 20 connected to the load 30 does not exceed 400W; in addition, if the sum of the output powers of all interfaces 20 connected to the load 30 does not exceed 400W, the normal output power is not limited in the embodiments of the utility model.

[0066] Further example: assuming that there are interface 1, interface 2, and interface 3, when interface 1 is first connected to a 200W load, because it does not exceed the rated output capacity of the control box (such as 400W), interface 1 outputs power normally; when interface 2 is then connected to a 400W load, the power reduction ratio is selected according to actual needs (for example, reducing the output of interface 2 to half the power); when interface 3 is connected to the load again, because interface 1 and interface 2 have already made the control box output at full load, the power output of interface 3 can be disconnected (that is, the power switching circuit is turned off), or interface 1, interface 2 and interface 3 can be subjected to power reduction operations. It can be flexibly set according to needs, and the embodiments of the utility model are not limited thereto.

[0067] It can be seen that this optional embodiment can limit the output power of all interfaces with loads connected, improve the rationality and reliability of the power output of the power supply and the interface, thereby improving the operating stability and safety of the control box, reducing the possibility of damage to the control box as a whole and the components included therein and the degree of operational damage, and improving the user experience and durability of the control box. In addition, under the normal output capacity of a control box, more loads can be operated or more loads can be flexibly controlled to operate, thereby achieving better load operation effects.

[0068] In yet another optional embodiment, Figure 2 As shown, each interface 20 has a corresponding power allocation priority. When multiple loads 30 are respectively connected to the corresponding interfaces 20, the main control chip 10 is specifically used to allocate corresponding output power to each interface 20 to which the load 30 is connected according to the power allocation priority corresponding to all interfaces 20 to which the load 30 is connected and the preset power threshold, and control the switching state of the corresponding power switching circuit 50 according to the allocated output power.

[0069] Optionally, the main control chip 10 controls the switching state of the corresponding power switch circuit 50 according to the allocated output power. For example: when the output power required to be allocated to a certain interface is 0, the main control chip 10 controls the switching state of the power switch circuit 50 corresponding to the interface to be in a closed state (that is, not powered on); when the output power required to be allocated to a certain interface is not 0 and is less than or equal to a preset power threshold, the main control chip 10 controls the switching state of the power switch circuit 50 corresponding to the interface to be in an open state (that is, powered on). The embodiments of the present utility model are not limited thereto.

[0070] Optionally, the power allocation priority corresponding to interface 20 may be determined by the order in which the loads of different interfaces 20 are accessed, for example, the earlier an interface 20 accesses load 30, the higher the power allocation priority of the interface 20; the power allocation priority corresponding to interface 20 may be determined by load access user information of different interfaces 20; the power allocation priority corresponding to interface 20 may also be determined by access load information of different interfaces 20, for example, allocating according to the required power size of the access load; the power allocation priority corresponding to interface 20 may also be determined by a predefined load input power sequence, for example, the user sets it according to his own needs; or the user may independently select the interface for output power, which is not limited in the embodiments of the utility model.

[0071] It can be seen that this optional embodiment can perform output power distribution and power switch circuit control according to the power distribution priority corresponding to the interface and the preset power threshold, thereby improving the power distribution rationality and power distribution flexibility of the interface with load access, as well as improving the control rationality and control accuracy of the power switch circuit, thereby improving the degree to which the actual needs of users are met, while controlling loads of different power levels. In addition, it can also control more lighting scenes according to actual needs and carry more lamp loads under the normal output capacity of the control box to achieve a larger lighting area.
