Status data package is status information bag；LED lamp（2）The status data package of oneself is first sent after receiving order, is being received
To LED lamp（1）State package after to LED lamp（3）Send LED lamp（1）State package.The like.Last
Individual LED lamp 3 is LED lamp（N）By state exhausting line, the status information package of all LED lamps 3 is sent to DMX512
Controller 2.
Step 5, the DMX512 controllers 2 will be all after the status information bag of all LED lamps 3 is received
The status information encapsulating bag of the LED lamp 3 is transferred to the host computer 1；In the utility model embodiment method, DMX512 controls
After device 2 processed receives all status information data packages of last root LED lamp 3 transmission, by TCP/IP procotols, via
Netting twine is sent to PC/ work stations 1.
The host computer 1 judges the use longevity of each LED lamp 3 according to the status information bag of each LED lamp 3
Life.Preferably, lm80 data reportings are stored with the host computer 1, the host computer 1 believes the state of each LED lamp 3
Breath bag and the contrast of lm80 data reportings judge the service life of each LED lamp 3；Judging the state of each LED lamp 3
When, the meeting of host computer 1 institute according to corresponding to calculating the current average, the average voltage and the temperature averages
State the power average value of LED lamp 3, afterwards with reference to the LED lamp 3 various states and lm80 data reportings as in lm80
The data such as temperature or luminosity are contrasted, and the instantaneous operating conditions of each LED lamp 3 of analytic statistics, judge each LED lamp 3
Actual life, send early warning, and generate light fixture actual life report.Meanwhile this report is sent to cloud platform
Control data corporation.
From the foregoing, it will be observed that the utility model can utilize the light fixture virtual condition numerical value of DMX512 data packets transmission, contrast
Lm80 data reportings, the real use state of light fixture by composite factors such as temperature, power, usage times, can be calculated, and then
Judge the actual life of light fixture, to carry out the preparations such as the production of replacing light fixture and installation in advance, greatly improve work
Make efficiency.Following all data summarizations are easy to manage concentratedly to cloud platform control data corporation.
In addition, in the utility model, the time slot between DMX512 data packets is relevant with the display frame frequency of system, frame
Frequency is higher, and time slot is shorter, and the information that can be transmitted is fewer.The data packet for needing reasonable disposition state to transmit.Each
The status data of a light fixture is transmitted in time slot；How many light fixture just needs how many individual time slots in bus；Therefore it is complete
At least needed the time required to the state recovery of all light fixtures on into bus：T=light fixture quantity ×（1/ system frame frequency）.
The utility model is described in detail above by specific embodiment, but these are not formed to this practicality
New limitation.In the case where not departing from the utility model principle, those skilled in the art can also make it is many deformation and
Improve, these also should be regarded as the scope of protection of the utility model.
