Description
Technical Field
The utility model relates to an L ED drive power supply technical field particularly, relates to a compatible multiplexing L ED drive power supply of many interfaces.
Background
The intelligent technology is developed day by day, and is different day by day, and has been deepened into various industries, the intelligence is an inevitable development trend, and is known as a new industrial revolution, and the trend can be caught up only when the intelligent technology is advanced, the L ED driving industry is the same, at first, the L ED driving only plays a role of simple lighting, and does not have intelligent control and software programming, the original L ED driving power supply only outputs a constant current or voltage, so that the requirements in the aspects of dimming, control and programming are not needed, the requirements are single, only the output is stable, and the light does not flicker.
The intelligent L ED driving power supply has problems that a programming interface is required to be added on a shell of the driving power supply if internal programs need to be modified and upgraded at any time, a dimming interface is required to be added if an external dimmer needs to be connected, a plurality of dimmers on the market need to be externally connected with a 12V direct current power supply to work, and a communication interface is required if the operation parameters of the driving can be changed and monitored at any time.
The most common method in the prior art is that a programming interface is arranged in a power supply, programming must be completed before the power supply is installed in a shell, and once the power supply is installed in the shell and glue is filled, the internal program cannot be modified. Then, a communication interface and a dimming interface are respectively installed on the side covers of the shell, and the most common method for supplying power to the dimmer at present is to add a constant-voltage power supply to the dimmer, which increases the cost. And in order to carry out communication monitoring or modify the operation parameters in the power supply, alternating current must be input into the power supply, so that the power supply can be operated in a working state. By doing so, the material cost and the production cost are increased, the operation is very inconvenient, and the requirement on the environment of the operation site is high (alternating current input is required to supply power to the driving power supply). And the produced driving power supply cannot modify and upgrade the internal program. In this way, if there is a problem in the program, the entire driving power supply may not work properly or even be discarded. If new functions are added to the software, the software must be produced again, and the software cannot be upgraded directly on the finished product. Not only increases the risk but also indirectly increases the cost.
Fig. 3 is a general programming interface, and as shown in the drawing, VREF is used as a power supply interface in the programming interface, and the programmer can provide a working voltage of 3.3V or 5V to the single chip microcomputer through this pin. P1.6 is used as an ICPDA, ICP programming data input/output pin, programming data is transmitted from this interface, and since this pin is used as both input and output of data, half-duplex communication is possible. P0.2 is used as ICPCK and is an ICP programming clock input pin, and the burner inputs a fixed square wave to the singlechip through the pin and is used as a programming input clock. RST is a reset pin that is used to reset the chip with an external signal and is also used to enter or exit ICP mode during programming. When RST is in low level, a string of specific data is input on P1.6, the single chip microcomputer enters an ICP mode, then RST is set high, and programming is started. And after all the programming data are transmitted, resetting the RST, resetting the singlechip and exiting the ICP mode.
Fig. 4 is a diagram of a conventional TT L serial port communication model, and as can be seen from fig. 4, in a more conventional TT L serial port communication circuit, four lines VCC are generally required to provide a 3.3V or 5V working voltage for a single chip microcomputer, although if other VCC supply sources are provided, the four lines are not required, RX, data is transmitted to a receiving pin of the single chip microcomputer by a TT L adapter, TX, data is transmitted by a transmitting pin of the single chip microcomputer, and finally, the ground line is used.
Fig. 5 is a diagram of a conventional dimming signal detection circuit, and it can be seen from fig. 5 that at least two wires are required in the conventional dimming process: DIM, dimming signal input line; DGND, dimming signal ground.
From the above analysis, if the conventional way is used, 3 interfaces and many wires are required to simultaneously realize the functions of programming, communication and dimming for L ED driving power supply.
An effective solution to the problems in the related art has not been proposed yet.
