Embodiment 1

[0017] figure 2 It is a display video wall system with 3 rows and 4 columns, which is composed of 3*4 display units, and each display unit has a network interface (used to communicate with the information of the splicing processor) and a display input interface (respectively from The display output of the display processor), each video wall unit has a cooling fan, which can be controlled by the video wall unit, and the video wall unit is managed by the fan centralized control management module. A fan centralized control management module is designed inside the splicing processor.

[0018] Set T1=30 degrees Celsius, T2=40 degrees Celsius, n=60 seconds

[0019] Divide into 4 groups of 3 each. When it is detected that the temperature of a certain splicing display unit exceeds T2, turn on the fan of the splicing display unit; when it detects that the temperature of a certain splicing display unit is lower than T1, turn off the fan of the splicing display unit; When the tempera...

Embodiment 2

[0025] 10 rows and 5 columns display the video wall system, T1=25 degrees Celsius, T2=35 degrees Celsius, T3=40 degrees Celsius, n=60 seconds, the main fan connected to each video wall display unit has 2 levels of speed, divided into high speed and low speed.

[0026] Divide into 10 groups of 5 each. Cycle for up to 5 minutes. Each splicing display unit is connected through an Ethernet network, and the splicing processor is responsible for the centralized control and management of the fans.

[0027] When it is detected that the temperature of a certain splicing display unit exceeds T3, the fan high-speed operation mode of the splicing display unit is turned on. When it is detected that the temperature of a splicing display unit is lower than T1, the fan of the splicing display unit is turned off; when the temperature of a certain splicing display unit is between T1 and T2, these splicing display units are controlled in turn, each Only one splicing display unit in the group i...

Embodiment 3

[0029] 10 rows and 5 columns display the video wall system, T1=25 degrees Celsius, T2=35 degrees Celsius, T3=40 degrees Celsius, n=60 seconds, the main fan connected to each video wall display unit has 2 levels of speed, divided into high speed and low speed.

[0030] Divide into 10 groups of 5 each. Cycle for up to 5 minutes. Each splicing display unit is connected through an Ethernet network, and the splicing processor is responsible for the centralized control and management of the fans.

[0031] Every 60 seconds, each splicing display unit in each group detects the temperature of each device, compares the temperature of each splicing display unit in the same group, and selects the splicing display unit with the highest temperature (if there are more than 2, choose arbitrarily) First), look at the temperature of the splicing display unit, and control the fan of the splicing display unit according to the situation (turn off when it is less than T1, run at low speed when it ...

Abstract

The invention provides a sequential start control method of fans of many kinds of heat generating equipment and application. In the method, a fan centralized control management module is used for centralized control on all fans, the same set of heat generating equipment with the temperature of T1-T2 carries out heat radiation in a mode of sequentially starting the fans, the fans with the temperature lower than the lower limit value T1 are turned off, and the fans with the temperature higher than the upper limit value T2are started, thereby the noise resonance and interference caused by simultaneously starting all fans are effectively reduced, and in particular, when the temperature of the heat generating equipment is lower than T2, the effect of doubled reduction is achieved; meanwhile, the method also saves power, realizes automated control, has the advantages of simple operation, small misoperation rate, flexibility and convenience and is beneficial to generalization and application. The sequential start control method has importantly practical significance on the traditional large-scale wall splicing systems.

Description

technical field [0001] The invention relates to a fan switch control technology, in particular to a method and application for controlling the fans of multiple heating devices in turn. Background technique [0002] At present, multiple heat-generating devices, such as electronic devices, are used more and more intensively. The heat dissipation noise problem of the machine is getting more and more serious. [0003] No matter the temperature is high or low, if the cooling fans of multiple electronic devices are activated at the same time, it will bring a lot of noise to the environment. For example, in a splicing display wall with 10 rows and 5 columns, when more than 50 fans are started at the same time, the resonance of the noise will affect the audience's experience. Each effective video wall has individual fan control, such as turning off the fan when the temperature of the display unit is low, and turning on the fan when the temperature of the display unit is high. In ...
