The working principle of the embodiment of the present invention is elaborated as follows:
The present invention has comprised two kinds of intelligent fan speed-regulating modes, and the user can, according to the concrete running environment of equipment actual conditions and equipment, select suitable speed-regulating mode, and rationally carry out parameter configuration.These two kinds of patterns are respectively ladder speed-regulating mode and return difference speed-regulating mode, are described as follows:
(1) ladder speed-regulating mode
The schematic diagram that Fig. 2 is rotation speed of the fan and temperature under the ladder speed-regulating mode, as can see from Figure 2, rotation speed of the fan remains unchanged in certain temperature range, when temperature variation reaches certain step value, equipment carries out fan speed-regulating automatically, be the shelves speed that equipment correspondence under different temperature ranges is different, the formula of its rotation speed of the fan is: rotating speed=(Current Temperatures-initial temperature)/temperature step value+rotating speed initial value.As long as rationally set these three parameters of initial temperature, initial rotating speed and temperature step value; equipment just can be selected suitable shelves speed operation automatically according to Current Temperatures; move to reduce device temperature and protection equipment with high-grade rotating speed under hot environment, under low temperature environment, with low-grade speed, move to reduce fan noise and equipment power dissipation.
(2) return difference speed-regulating mode
The schematic diagram that Fig. 3 is rotation speed of the fan and temperature under the return difference speed-regulating mode, as can see from Figure 3, in the time of in the operating temperature range that temperature is set at equipment, rotation speed of the fan remains unchanged; When temperature, during higher than the Maximum operating temperature set, equipment just starts raising speed until the most high-grade speed or device temperature reduce, and rotating speed just can effectively reduce device temperature after promoting, to protect equipment; When temperature, during lower than the minimum operating temperature set, equipment just starts reduction of speed until lowest gear or device temperature rise up, so just can reduce fan noise and equipment power dissipation.Under this speed-regulating mode; the user does not need to pay close attention to too much speed governing parameter; as long as set the operating temperature of equipment; equipment just can be according to current ambient conditions automatic speed regulation; raising speed under hot environment; reduction of speed under low temperature environment reduces fan noise and equipment power dissipation when protecting equipment.
Below in conjunction with practical engineering application, illustrate the setting parameter under ladder speed-regulating mode and return difference speed governing model.Suppose in Practical Project, equipment is operated in 30～60 degree scopes, and the fan speed-regulating gear is 1～7 grade, and wherein 7 grades of rotating speeds are the highest, and the temperature of equipment in machine room is generally 45 degree left and right.
When equipment moves under the ladder speed-regulating mode, its speed governing parameter can be made as: initial rotating speed is 1 grade, and initial temperature is 30 degree, and the temperature step value is 5 degree.The corresponding relation of temperature and rotating speed is as shown in table 1, and as can be seen from the table, equipment is different in the interval internal fan operation of different temperatures shelves speed, at high temperature, with high rotating speed operation, with the slow-speed of revolution, moves at low temperatures.When temperature is that 45 rotating speeds while spending are 4 grades, this grade of speed is middle-grade rotating speed, when reducing device temperature, also can reduce fan noise, is adapted at moving under general building environment; When temperature 34 degree and when following rotating speed be 1 grade, fan noise minimum under this rotating speed, the power consumption of equipment is also minimum, is adapted at moving under low temperature environment; When temperature 60 degree and when above rotating speed be 7 grades, reduction device temperature that can be best under this rotating speed, avoid because of excess Temperature infringement equipment.
The corresponding relation of table 1, temperature and rotating speed
| Rotating speed | Temperature |
| 1 | Below 34 degree reach |
| 2 | 35～39 |
| 3 | 40～44 |
| 4 | 45～49 |
| 5 | 50～54 |
| 6 | 55～59 |
| 7 | More than 60 degree reach |
Can establish operating temperature range when equipment moves under the return difference speed-regulating mode is 45～50 degree.When temperature equipment higher than 50 time starts raising speed, after a period of time, if device temperature still could not reduce, continue raising speed, be raised to the most high-grade or device temperature always and reduce.When temperature is spent lower than 45, equipment starts reduction of speed, if device temperature does not rise, continues reduction of speed, is reduced to lowest gear always.Under the return difference speed-regulating mode, equipment is the energy stable operation in setting operating temperature range, after temperature changes, can feed back immediately and speed governing.It should be noted that: the operating temperature range of setting can not be excessive can not be too small, excessive equipment can't automatic speed regulation, the too small klystron oscillator that easily produces.
Be more than illustrating of applying under specific environment of intelligent speed-regulating scheme, dissimilar equipment can, with reference to the method, rationally arrange the speed governing parameter under varying environment.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these are revised and modification belongs within the scope of the claims in the present invention and equivalent technologies thereof, these modifications and modification are also within protection scope of the present invention.
The prior art that the content of not describing in detail in specification is known to the skilled person.
