Description
Technical field
The utility model relates to LED and drives, and especially relates to a kind of selecting type zero attenuation compensation system of tabling look-up based on menu.
Background technology
Going from bad to worse of energy crisis, greenhouse effect and ecologic environment forces people more and more to pay attention to improving the technology of efficiency of energy utilization and environmental protection.LED (Light Emitting Diode, semiconductor light-emitting-diode) light source, not contain the advantages such as noxious material, environmental protection, the life-span is long, photoelectric efficiency is high, has obtained application more and more widely at lighting field.LED light source provides direct current by a constant current source as driver.Although LED light source is driven by constant current source, due to the aging action of chip and fluorescent powder, the luminous flux of LED light source output can descend along with the time, and the luminous flux of LED light source can be decayed gradually.Traditional LED attenuation compensation scheme is generally that attenuation compensation information directly is cured in LED power storage unit, this mode is difficult for change after information writes, when light source is used the scheme that neither one carries out unified management to a plurality of LED attenuation compensation power supplys when more, and the concrete condition of each LED attenuation compensation is difficult for monitoring, be not easy to management.
The utility model content
The purpose of this utility model be exactly provide a kind of unified management in order to overcome the defect that above-mentioned prior art exists, control flexibly, the selecting type zero attenuation compensation system of tabling look-up based on menu of monitoring in real time.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of selecting type zero attenuation compensation system of tabling look-up based on menu, it is characterized in that, comprise terminal server, control desk and LED driver module, described terminal server is connected with a plurality of control desks by system bus, and each control desk is connected with a plurality of LED driver modules;
Described terminal server, according to the LED driver module corresponding to address selection of user's input, simulates the light decay curve of LED according to input message, then according to the corresponding relation of LED brightness and electric current, calculate the current compensation rate; Under monitor state, terminal server is run-down at regular intervals, power on and read its working time when the LED driver module being detected, terminal server judges the adjustment interval at this of place working time, and find the interval corresponding current output value of this adjustment in the current compensation rate curve of this LED driver module, and this current output value is sent to this LED driver module;
The LED driver module rear internal system time clock that powers on starts timing, and will be preserved working time, during when the query statement that receives terminal server and with own matching addresses, terminal server will be fed back to the working time of oneself, and read self the storage the preset current cancellation ratio, if terminal server has current compensation rate update request, from preset current compensation rate with find corresponding output current parameter the output current relation table, thereby adjustment output current, stablize LED brightness, and more new data is preserved.
When described terminal server is accessed certain LED driver module, at first by system bus, find the control desk under this LED driver module, this control desk connects with it according to LED driver module address information.
Described system bus is wireless or Ethernet.
Described LED driver module comprises communication interface, storage unit, system clock, reseting port and control driving circuit, and described reseting port, system clock, storage unit, driving circuit connect successively, and described communication interface is connected with storage unit.
Described cell stores has the driver module address.
Compared with prior art, the utility model is carried out unified management to each module in system, the attenuation compensation parameter of each module can be set easily, can monitor in real time each module operation conditions, except basic attenuation compensation function, the utility model can also be carried out timesharing brightness adjustment control (brightness of LED can be adjusted into 70% of night such as daytime, to save the energy) to the system inner module easily on former balanced basis, in real time manual brightness adjustment control etc., be particularly suitable for factory and use.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1-2, a kind of selecting type zero attenuation compensation system of tabling look-up based on menu, comprise terminal server, control desk and LED driver module, described terminal server is connected with a plurality of control desks by system bus, each control desk is connected with a plurality of LED driver modules, described LED driver module comprises communication interface, storage unit, system clock, reseting port and controls driving circuit, described cell stores the driver module address.When terminal server need to be accessed certain LED driver module, at first by system bus, find the control desk under this LED driver module, control desk connects with it according to LED driver module address information.
The modes such as that described system bus can adopt is wireless, Ethernet.
Described control desk carries out signal processing and communication modes conversion, according to the communication interface situation of each LED driver module, is selected communication modes, and described communication modes comprises ZigBee, PLC, RS485 or other modes.
Workflow of the present utility model comprises the following steps:
The first, terminal server, according to the LED driver module corresponding to address selection of user's input, simulates the light decay curve of LED according to input message, then according to the corresponding relation of LED brightness and electric current, calculate the current compensation rate.As shown in Figure 3, terminal server generates the current compensation rate and has two kinds of modes: the first is the User Defined mode, the part relations point that software is decayed in time according to the LED brightness of inputting simulates LED light decay curve, then by LED brightness and current relationship, calculates the corresponding current cancellation ratio; The second is to select existing curve mode, and software is according to the LED manufacturer of selecting, model, and the information such as junction temperature are found out corresponding LED light decay curve from database, then by LED brightness and current relationship, calculate the corresponding current cancellation ratio.
As shown in Figure 4, under monitor state, terminal server is run-down at regular intervals, power on and read current LED driver module working time when the LED driver module being detected, and judge the adjustment interval at this of place working time, whether judgement is adjusted interval and is changed, and does not change and skips over and scan next address; Change finds the value of the current compensation rate of this interval correspondence to send this LED driver module to according to current adjustment is interval from the current compensation rate curve of this LED driver module.
As shown in Figure 5, the LED driver module rear internal system time clock that powers on starts timing, and will be stored in storage unit working time, during when the query statement that receives terminal server and with own matching addresses, fed back to terminal server the working time of oneself, and preset current compensation rate in reading cells, judge whether terminal server has the update request of current compensation rate: no, skip over, keep primary current output; Be, from preset current compensation rate, with the output current relation table, find corresponding current parameters, by driving circuit, adjust output current, stablize LED brightness, and more new data is saved in storage unit.
