Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 2 , image 3 As shown, based on the broadcast method to realize addressing fault identification method when addressing smart lamps, the controller broadcasts multiple addressing data in sequence, and multiple lamps to be addressed are connected in series through addressing lines to form a series circuit, and the phase of the series circuit The address input terminal of the next lamp in the adjacent lamps is connected with the address output end of the previous lamp through the address line, so that the level of the address input terminal of the next lamp in the adjacent lamps follows the write address of the previous lamp. The level of the output terminal changes, and the write address input terminal of the first lamp in the series line is floating, so that the write address input terminal is at a high level, and each lamp detect...

Abstract

The invention discloses a method for realizing address writing fault identification during address writing of an intelligent lamp based on a broadcasting mode. According to the method, a controller detects the level of the address writing output end of the last lamp in real time during address writing data broadcasting; the controller counts the number of broadcasted address writing data when broadcasting the address writing data, stops broadcasting when detecting that the address writing output end of the last lamp is at a high level, and obtains the number n of broadcasted address writing data; and the controller compares the number n of the address writing data broadcasted at the moment with the total number of the address writing data needing to be broadcasted, judges whether a fault occurs and identifies the fault position. According to the invention, the address writing line connection fault and the fault position are detected in real time in the address writing process, and themethod has the advantages of accurate fault detection and identification and high efficiency.

Description

technical field [0001] The invention relates to the field of address writing methods for intelligent lamps of the Internet of Things, in particular to an address fault identification method for address writing of intelligent lamps based on broadcasting. Background technique [0002] At present, when writing addresses for smart lamps that can realize the Internet of Things, the controller generally communicates with each smart lamp based on the Dmx512-A protocol. The Dmx512-A protocol adds a write address line on the basis of the Dmx512 protocol, and the level changes of the input and output terminals of the lamp through the write address line cooperate with the write address. [0003] The principle of address writing of smart lamps based on the Dmx512-A protocol in the prior art is as follows: figure 1 As shown, each intelligent lamp is connected in series through the addressing line to form a series circuit, that is, the addressing input terminal of the next intelligent la...
