Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.

It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.

Example 1

The application aims at providing a method for realizing automatic detection channel and automatic address writing of a lamp, and specifically, referring to fig. 1-3, the method comprises the following steps:

s00, after the lamp is powered on for the first time, outputting DO signals to the LED driver through the decoder when no external lamp control signals (no RS485 signals or no DMX512 signals) exist;

as shown in fig. 2, each lamp is electrically connected with a controller for emitting an external lamp control signal (RS 485 is used as a physical layer standard, the controller is connected with the lamp by using an RS485 bus), a decoder is arranged in each lamp, each decoder is connected with a plurality of LED drivers in series, each LED driver is connected with one or a plurality of LED lamps, and decoders of two adjacent lamps are connected with each lamp in turn by PI-PO lines;

the DO signal refers to a digital output signal (Digital Output Signal) which is a type of signal used to transmit discrete states or switching signals in a digital electronic system. The DO signal typically has only two possible states, typically denoted 0 and 1, corresponding to a low level (typically 0 volts) and a high level (typically 5 volts or 3.3 volts, depending on the system voltage standard), respectively. The DO port refers to the signal output.

While DI signals refer to digital input signals (Digital Input Signal), a type of signal used to transmit discrete state or switching signals in digital electronic systems. The DI signal typically has only two possible states, typically denoted 0 and 1, corresponding to a low level (typically 0 volts) and a high level (typically 5 volts or 3.3 volts, depending on the system voltage standard), respectively. DI port refers to a signal input.

In this embodiment, after the first power-on, the decoder generates a DO signal according to the RS 485-free default state configured by factory and loads the DO signal to the LED driver.

in this embodiment, the decoder DO side is connected in series with each LED driver in a fixture, and returns to the DI port of the decoder itself through the final LED driver. The decoder is separated from the driver, and the decoder mainly receives an external lamp control (DMX 512) signal and converts the external lamp control signal into a DO signal to control the LED driver. The LED driver is mainly used for receiving signals of the decoder to generate PWM signals for driving the control lamp, the driver is not the content protected by the application, and the existing driver chip can receive signals conforming to rules from the DI port of the driver to drive the LED lamp and forward the DI signal to the DO port of the driver after eliminating the used part of the DI signal.

in this embodiment, as shown in fig. 3, since the DI port of the LED driver receives the signal from the front decoder or the front LED driver, the data of the number of self-matched channels is output and driven (as shown in fig. 3, the data of one Byte1 is less in the lower DO) through the driving conversion, and then the remaining signal is output through the DO port of the driver, and then the signal returned to the DI port of the decoder after passing through a plurality of drivers is the remaining signal. The comparison is received by the decoder and, the self-calculation can be performed number of body passages n=n=n _DO -N _DI Wherein N is _DO Channel number, N, of DO signal for decoder _DI The number of channels of the remaining signal (which is input to the DI port of the decoder) output for the last LED driving unit.

Thus, the channel number generated by the comparison is stored in the storage unit of the decoder, and if the channel number is inconsistent according to the real-time comparison condition, the channel number is updated.

Wherein Rst in fig. 3 is a low level reset signal or a low level reset code.

S30, transmitting a mute canceling state signal to each decoder through the controller, and setting the PO signal of each decoder to be low after each decoder receives the mute canceling state signal; the PO end of the upper-level decoder is connected with the PI end of the lower-level decoder, and the PI end of the first-level decoder has no input;

in this embodiment, the controller first sends a "disc_un_mute" disable flag (disable MUTE state signal), and the decoder sets its own PO signal low after receiving the "disc_un_mute". Here, "disc_un_mute" is a command in the RDM protocol, which means to cancel the MUTE flag of the device. In the RDM protocol, the device may be set to a mute state, meaning that the device does not respond to a query command or configuration request from the controller. By sending the DISC _ UN _ MUTE command, the controller may request the device to cancel the MUTE state, causing the device to resume responding and communicating with the controller.

Therefore, since the PO port of the upper decoder is connected to the PI port of the lower decoder, the DI input signal of the corresponding lower decoder becomes low, and since the PI port of the first decoder has no input, and the pull-up resistor is built in the PI port of the decoder, the input PI of the first decoder is high.

where the "Get" command typically includes an identifier of a parameter or attribute that specifies the type of information that the controller wishes to obtain. After receiving the "Get" command, the device searches for the corresponding parameter or attribute and returns its value to the controller as a response. This allows the controller to query the various status, configuration and performance information of the device for device management and monitoring.

in this embodiment, after the controller sends the "Get" command containing the broadcast, the decoder performs exclusive-or (pi≡po) calculation on its own input PI and output PO, and if the result is "0" (input and output are unequal), the decoder submits its own channel number to the controller. The decoder with exclusive or value "1" remains silent. After the answer is finished, the answer decoder sets the output PO of the answer decoder to be the same as the input PO (set to be high), and enters a mute state.

in this embodiment, the controller sorts the received channels according to the number of channels and provides a basis for address writing. And judging that the query is finished only by no broadcast response channel number.

The code writing instruction for writing address is generated by sequentially adding the read channel number according to the given initial address.

For example, the controller firstly sends a broadcast acquire DEVICE COMMAND "get_command+device_info", and the first unmuted DEVICE replies "ack+get_command_response+pd", wherein PD (Parameter Data) contains DMX512 Footprint information, which is the number of channels of the current DEVICE, and is recorded as N0, and the controller circularly sends the acquire DEVICE information COMMAND, and records the RESPONSEs received each time as N0, N1, N2 … Nn. And when no response occurs twice, the equipment acquiring information is considered to be acquired.

Repeating the steps again, re-acquiring the channel numbers M0, M1, M2 … Mn, and carrying out corresponding comparison checking with N0, N1, N2 … NN, wherein the checking is successful if all the channel numbers are the same, otherwise, the re-acquisition is failed.

After the channel number sequence is successfully acquired, the controller sets the starting address to be A0, and calculates A1=A0+N0, A2=A1+N … An=A (N-1) -N (N-1) (remark: nn ignores the follow-up no device).

Finally, the DM512 address command 'RstA+0x00+A0', 'RstA+0x00+A1' … 'RstA+0x00+an' (RstA is a low level mark exceeding 2s and is an address resetting code) is adopted for writing codes. And after the lamp receives the address resetting code for the first time, PO is set low, and Po and Pi are compared. If not, storing the corresponding address into the address space of the device, setting high PO and entering the default state. And so on until all lamps are addressed.

The above general process of generating a code-writing instruction is by way of example only.

in this embodiment, the controller first sends a "disc_un_mute" disable flag, and the decoder sets its own PO signal low after receiving the "disc_un_mute".

in this embodiment, when the controller sends a code writing instruction that finishes encoding according to the ordering, the decoder performs exclusive or (pi≡po) on its own input PI and output PO, and if it is "0" (the input and output are different), writes the corresponding address code into its own storage area, and sets its own output PO to be the same as the input PO. The decoder with the exclusive or value "1" waits.

In this embodiment, since the first stage exclusive-or is "0" first, writing is performed. Then outputting a high level results in the second stage exclusive or being "0", the second stage begins to receive and store the second address code, and then outputting PO high results in the third stage exclusive or being "0". And so on, until all the PO of the decoder becomes high, the code writing is finished.
