Description
Technical field
The present invention relates to a kind of fan swicth control technique, particularly a kind of fan of many heat-producing devices takes turns start-up control method and application.
Background technique
At present, many heat-producing devices are concentrated use more and more widely as electronic equipment.The heat radiation noise problem of machine is more and more serious.
No matter temperature just if the radiation fan of multiple electronic equipment starts simultaneously, all can bring very big noise to environment.Such as, the spliced display wall of 10 row, 5 row, when having 50 above fans to start simultaneously, the sympathetic response of noise has influenced spectators' impression.All there is independent fan control each effective tiled display unit, such as close fan when the display unit temperature is low, opens fan when the display unit temperature is higher.In this case, exist most display units to open and close the phenomenon of fan together, cause random noise level to change, also allow the watcher more feel bad sometimes.How effectively managing and control these fans, to alleviate noise be urgent problem in the industry.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of fan of many heat-producing devices to take turns the start-up control method, native system has realized that the fan timesharing of many heat-producing devices starts, and effectively reduces noise.
Another object of the present invention is to provide the fan of above-mentioned many heat-producing devices to take turns the application of start-up control method.
The objective of the invention is to be achieved through the following technical solutions: a kind of fan of many heat-producing devices takes turns the start-up control method, wherein, every heat-producing device all is connected with 1 desk fan at least, heat-producing device is divided into the m group, every group of n platform, be provided for the detection facility temperature and go to the temperature sensing circuit that reaches fan concentrated controling management module at every heat-producing device, and be used to control the fan control module that its fan that connects opens and closes; All temperature sensing circuits are connected to a fan concentrated controling management module, be provided with lowest temperature value T1, temperature upper limit T2 and opening time n second in the fan concentrated controling management module, when the temperature that receives certain heat-producing device from temperature sensing circuit when fan concentrated controling management module surpasses T2, send instructions to fan control module, to open the fan that this heat-producing device is connected; When the temperature that detects certain heat-producing device is lower than T1, send instructions to fan control module, to close the fan that this heat-producing device is connected; When detecting same group the temperature of some heat-producing device at T1～T2 during the time, these heat-producing devices are taken turns switch control, each group heat-producing device is only driven wherein fan that heat-producing device connected, and the opening time is n second; After time n reaches second, change same group next temperature and open at the fan that the heat-producing device of T1～T2 time carries out n second, wherein, m, n are the natural number greater than 1.
In the said method, described fan concentrated controling management module detects same group the temperature of some heat-producing device at T1～T2 during the time, these heat-producing devices are taken turns switch control, and each group heat-producing device is only driven wherein fan that heat-producing device connected, and the opening time is n second; After time n reaches second, fan concentrated controling management module detects the temperature of other heat-producing device of same group once more, then same group next temperature is opened at the fan that the heat-producing device of T1～T2 time carries out n second, that is to say that fan concentrated controling management module is carried out once the detection of temperature of same group heat-producing device second every n.
The fan that said method can be applicable to the display splicing wall system takes turns start-up control, specifically: each tiled display unit is considered as heat-producing device, each tiled display unit all is connected with 1 desk fan at least, all tiled display unit are divided into the m group, every group of n platform, in each tiled display unit described temperature sensing circuit is set, and described fan control module; At the splicing processor described fan concentrated controling management module is set.
When the fan that said method is applied to the display splicing wall system took turns start-up control, communicating by letter between temperature sensing circuit and the fan concentrated controling management module adopted the tiled display unit and spliced that existing communication interface communicates between the processor.The cost of so can the reduction system realizing.
The present invention has the following advantages and beneficial effect compared to existing technology:
The present invention adopts fan concentrated controling management module that all fans are carried out centralized control, be in the T1～heat-producing device of T2 in the time same group of temperature, the mode that employing takes turns starting fan is dispelled the heat, and the fan that is lower than lowest temperature value T1 cuts out, the fan that is higher than temperature upper limit T2 is opened, effectively reduce all fans and open the noise sympathetic response interference that is brought simultaneously, especially when T2 is following, reach at double the effect that descends when the heat-producing device temperature, also saved simultaneously power supply, and realized automation control, simple to operate, misoperation rate is little, flexible, help promoting and application.Particularly, great Practical significance is arranged for existing extensive combination system.
