Description
Technical Field
The invention relates to the technical field of LED controllers, in particular to a synchronous controller compatible with multiple voltages.
Background
Currently, there are various control types of LED controllers in the existing market, wherein the LED controller is most commonly controlled in a form of RF wireless remote control, so as to achieve control and adjustment of the brightness or color of the connected LED module and various conversion combinations, but the control goal of achieving LED modules with different voltages is complex and the effect is not ideal. Specifically, the following two scheme architectures are mainly adopted:
(1) scheme a as shown in fig. 1: the control system is composed of a plurality of independent components such as a plurality of power supplies, a plurality of controllers, a remote controller, a plurality of voltage modules and the like, and is used for controlling the LED modules with different voltages. The utility model discloses a control method of the DC power supply, including the controller, the controller is used for receiving the control signal, the utility model provides a plurality of different power supplies power respectively after the commercial power input, can obtain the DC direct current of different voltages like this, then insert the same controller respectively (the controller is inside to contain signal receiving unit and the control unit), when the same controller received the same control signal, make the same transform control to the controller voltage, accept the direct current of accuse and deliver to the module of different voltages to reach the effect of simultaneous control.
The control connection mode adopted by the scheme has the following defects:
firstly, the wiring is complicated: each group of modules needs one power supply, one controller and one module in a connection control mode. If need place multiunit module on a stand, will need a plurality of power and the controller that correspond, so many power and controller are placed together, are unfavorable for practical application's spatial arrangement.
② complete synchronous control cannot be performed: because each controller needs to receive the model sent by the remote controller, the complex layout controllers are installed in different places, the phenomena of delay, loss, interference and the like exist in the received signals, and when the remote control operation is actually applied, complete synchronous control cannot be achieved, and one group or a plurality of groups of uncontrolled conditions can occur.
③ a wide voltage range controller is required, the input 12-36V or more depending on the module voltage.
Fourthly, the cost is high: multiple power supplies and multiple controllers, wire fittings, etc. need to be used.
High failure rate, complicated wiring, and failure of any node, which may affect the whole control effect.
Sixthly, the maintenance is inconvenient and the maintenance cost is high.
(2) Scheme B as shown in fig. 2: the scheme is composed of a single power supply, a plurality of voltage converters, a plurality of controllers, a plurality of voltage modules and a plurality of independent components. The utility model discloses a control device, including power converter, voltage converter, power converter, same controller (the controller is inside to contain signal receiving unit and the control unit), the power converter is connected to the power converter through the wire, obtains a stable direct current, then inserts voltage converter, obtains the direct current of different voltages by the power converter, then inserts the same controller (the controller is inside to contain signal receiving unit and the control unit), when a plurality of the same controllers received the same control signal simultaneously, makes the same transform control to controller voltage, receives the direct current of accuse and delivers to the module of different voltages to reach the effect of simultaneous control.
The control connection mode adopted by the scheme has the following defects:
firstly, the wiring is complicated: each module connection control mode needs one power converter, one controller and one module. If a plurality of groups of different voltage modules are applied simultaneously, a plurality of converters and controllers are needed, so that the voltage converters and the controllers are put together for application, and the problem of complex wiring and routing of a plurality of power converters and a plurality of controllers also exists.
② complete synchronous control cannot be performed:
i) if each controller is independently matched with a remote controller, the operation is complicated, the simultaneous control cannot be realized, or the one-touch control can be realized during the application.
Ii) if each group of connections uses the same controller, the same remote controller is used for operation, and because each controller needs to receive signals at the same time, in the actual use process, because the controllers can not be installed in the same place due to wiring requirements, the received signals can be delayed or unsynchronized, and the synchronous control can not be achieved completely.
③ a wide voltage range controller is required, the input 12-36V or more depending on the module voltage.
Fourthly, the cost is high: multiple power supplies and multiple controllers, wire fittings, etc. need to be used.
High failure rate, complicated wiring, and failure of any node, which may affect the whole control effect.
Sixthly, the maintenance is inconvenient and the maintenance cost is high.
In order to solve the above problems, it is necessary to design a novel synchronous controller compatible with multiple voltages.
