Furthermore, the terms "first" and "second," etc. are used for distinguishing between different objects and not for describing a particular sequential order.
The implementation of the utility model is described in detail below with reference to the specific drawings:
fig. 1 is a schematic structural diagram of an intelligent dimming gateway according to an embodiment of the present utility model. Referring to fig. 1, the smart dimming gateway 1 includes: the system comprises a serial port module 11, a main control module 12, a network module 13, a command conversion module 14 and at least one dimming interface 15.
Two ends of the serial port module 11 are respectively connected with a local dimming button and a first communication end of the main control module 12. The serial port module 11 is configured to obtain a dimming command output by the local dimming knob, convert the dimming command into a first command, and send the first command to the main control module 12.
Two ends of the network module 13 are respectively connected with a remote dimming platform and a second communication end of the main control module 12. The network module 13 is configured to obtain the dimming command output by the remote dimming platform, convert the dimming command into a second command, and send the second command to the main control module 12. The main control module 12 is configured to output an initial dimming signal according to the first instruction and/or the second instruction.
The input end of the command conversion module 14 is connected to the first output end of the main control module 12, and the output ends of the command conversion module 14 are respectively and correspondingly connected to one end of at least one dimming interface 15. The command conversion module 14 is configured to receive the initial dimming signal and convert it into different dimming signals, which are sent to the at least one dimming interface 15, respectively.
The other end of the at least one dimming interface 15 is connected with a dimming end of the controlled power supply or a dimming end of the controlled lamp.
In practical application, when dimming the lamp, if the power supply for supplying power to the lamp is a dimmable power supply, the lamp can be dimmed by controlling the dimming end of the dimmable power supply; if the lamp is provided with the dimming end, the lamp can be dimmed by controlling the dimming end of the lamp. Therefore, the dimming interface in the embodiment of the utility model can be connected with the dimming end of the controlled power supply and the dimming end of the controlled lamp.
The serial port module 11 may obtain the dimming command sent by the local dimming button and convert the dimming command into a first command, that is, a local dimming command. The network module 13 may obtain the dimming command sent by the remote dimming platform and convert the dimming command into a second command, i.e. a remote dimming command. The main control module 12 converts the received first instruction and/or second instruction into an initial dimming signal, and then the command conversion module 14 converts the initial dimming signal into a dimming signal acceptable by the controlled power supply or the controlled lamp, and sends the dimming signal to the controlled power supply or the controlled lamp via the dimming interface 15, so as to control the controlled power supply or the controlled lamp to perform dimming.
The serial port module 11 and the network module 12 are arranged to simultaneously receive the local dimming instruction and the remote dimming instruction, so that the controlled power supply or the controlled lamp can be subjected to dimming control through the remote dimming platform, and can also be subjected to dimming control through the local dimming button, the dimming control mode is increased, different dimming requirements of users are met, and the convenience of dimming of the users is improved.

That is, the first command contains a relative dimming value and the second command contains an absolute dimming value, so that the two dimming modes can be synchronized. That is, after dimming with the local dimming button, the user may also continue dimming with the remote dimming platform on the basis of local dimming; alternatively, after dimming with the remote dimming platform, the user may continue dimming with the local dimming button on a remote dimming basis. The local dimming information and the remote dimming information can be synchronously updated through the main control module, so that a user can flexibly use different dimming modes according to own requirements, and the dimming convenience of the user is improved.
Meanwhile, at least one dimming interface is arranged in the embodiment of the utility model and is respectively connected with the dimming end of the controlled power supply or the dimming end of the controlled lamp. Therefore, one intelligent dimming gateway can simultaneously dim and control a plurality of controlled power supplies and/or controlled lamps and lanterns, and dimming efficiency is improved.
In addition, the initial dimming signal output by the main control module 12 is typically a PWM signal of 3.3V, however, the dimming signals acceptable by the controlled power source and/or the controlled lamp are different due to different models of the controlled power source and/or the controlled lamp. Therefore, the embodiment of the utility model is provided with the command conversion module which is used for converting the initial dimming signal into different dimming signals so as to meet the dimming requirements of different controlled power supplies and/or controlled lamps.

The drain electrode of the second switch tube 1414 maintains a high level, so that the dimming interface also maintains a high level state, and the voltage value at the dimming interface is the same as the output voltage value of the adjustable power supply;
when the first output end of the main control module 12 outputs a low level, the first switching tube 1412 is turned off, the drain electrode of the first switching tube maintains a high level, the gate electrode of the second switching tube also maintains a high level correspondingly, and the second switching tube 1414 is turned on. The drain of the second switching tube 1414 is pulled low and the dimming interface is correspondingly pulled low.

The preset voltage value is determined by the output value of the adjustable power supply. The first power supply may output a 5V dc voltage for providing a high level state.

The input end of at least one relay module 16 is connected with the second output end of the main control module 12, and the output end of at least one relay module 16 is correspondingly connected with the power end of the controlled power supply or the power end of the controlled lamp respectively.
When a user wants to turn off the light, one method is to set a dimming signal of a dimming end of a controlled power supply and/or a controlled lamp to 0, and turn off the light by using the dimming signal; the other method is to directly turn off the controlled power supply and/or the power supply of the controlled lamp, thereby turning off the lamp light. Compared with the former method, the method of directly switching off the power supply can save more electric energy and reduce cost.
Thus, the relay module 16 is provided in the embodiment of the present utility model, and is used for turning off the controlled power supply and/or the power supply of the controlled lamp through the relay contact when the received lamp on/off command is received.
In practical applications, when the first instruction and/or the second instruction indicate to turn off the light, the main control module 12 outputs the off instruction after receiving the first instruction and/or the second instruction, and sends the off instruction to the relay module 16.

the other end of the relay interface 162 is correspondingly connected with the power end of the controlled power supply or the power end of the controlled lamp.
The relay control circuit 162 is configured to control the contacts in the relay interface 162 to be opened according to the off command output by the main control module 12, so as to disconnect the controlled power supply and/or the power supply of the controlled lamp.
Fig. 4 shows, by way of example only, 2 relay modules. But this is not a specific limitation on the number of relay modules. The user can set the number of relay modules according to actual needs.
Illustratively, referring to fig. 5, taking the controlled power supply as an example, a power line of a power supply terminal of the controlled power supply is connected to one contact in the relay interface 162, and the other contact in the relay interface 162 is connected to alternating current.
