Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 1 is an architecture diagram of each module for controlling the rotational speed of a fan according to an embodiment of the present invention, and as shown in fig. 1, the architecture includes: the device comprises a display control module, a fan speed regulation module, a main control module, a temperature monitoring module and a fan. The fan rotating speed is selected through the joint communication of the display control module, the fan speed regulating module and the main control module. In the whole working process, the temperature of the important device is monitored by combining the temperature monitoring module, and whether the current rotating speed of the fan is kept or not is determined according to temperature data, so that the safety of the important device is further guaranteed.
The fan speed regulation module and the display control module can be communicated with each other, the display control module can selectively control the fan speed regulation module to work under different speed regulation modes or functions, the fan speed regulation module can be rotated by a user to regulate the fan rotating speed gear, fan rotating speed gear information is transmitted to the display control module, the display control module simultaneously transmits the rotating speed gear information to the main control module, the main control module calculates the rotating speed of the fan according to the received rotating speed gear information, and the fan is controlled to work under different rotating speeds through PWM speed regulation. The temperature detection module of the important device is connected with the main control module, monitors the temperature condition of the important device and transmits the temperature condition to the main control module, when the temperature of the important device is in a controllable range (namely, less than or equal to a preset temperature threshold), the fan speed regulation module is started to work in a full gear (namely, all gears of the fan speed regulation module are in a usable state), and a user can automatically regulate the rotating speed of the fan from low speed to high speed according to actual requirements; when the temperature of the important components is too high, the selection range is limited to be selected only in a certain high-speed gear range or a full-speed gear range (namely, a certain high-speed gear of the fan speed regulation module is in a usable state). In order to remind a user of the current temperature rise state, a Light Emitting Diode (LED) lamp can be added on a display panel corresponding to the display control module, and when the temperature rise exceeds a controllable range, the LED lamp is lightened, and the fan speed regulation module is controlled to be effective only at a high-speed gear.
For example: when a user selects low-power gear working or a heat preservation function through the display control module, the fan speed regulation module starts a full-gear mode (other high-power working states or oil functions only enable high-gear rotating speed), the low-rotating speed can be adjusted and selected by the user, the temperature of an important device is monitored in the working process, when the temperature exceeds a certain range, the lowest-level high-speed gear is automatically jumped in (when a temperature warning lamp is arranged, the temperature warning lamp is turned on) and enters a low-speed gear failure state, only the high-speed gear can be selected, and the normal selection state can be recovered after the device is cooled (when the temperature warning lamp is turned off). When the fan enters a pause state or a shutdown state, the fan speed regulation module also starts a full-gear mode, any gear can be selected to control the fan to rotate, and when the temperature of an important device is reduced to a low-temperature range, the fan stops rotating and enters a standby state. In order to ensure the temperature rise requirement of important devices in the working process, the control logic of the temperature monitoring module is higher than the speed regulation mode selection of the display control module and the rotating speed selection of the fan speed regulation module. And the rotation speed is automatically adjusted to the lowest-level high-speed gear and the selection of the low-speed gear cannot be performed when the temperature of an important device is higher.
In the above scheme of the embodiment of the present invention, the gears are used for conveniently distinguishing rotation speeds of different degrees, and different gears represent different rotation speeds, for example, the gears are divided into a low gear, a medium gear and a high gear from low to high according to the rotation speed, wherein the low gear, the medium gear or the high gear may be further divided into a plurality of small gears, for example, the high gear may be divided into a plurality of stages, and the rotation speed of the low-level high gear is lower than that of the high-level high gear. The user selects gears in the fan speed regulating module, namely the user selects the rotating speed for the fan.
Fig. 2 is a first schematic flow chart of a method for controlling a rotational speed of a fan according to an embodiment of the present invention, and as shown in fig. 2, the method for controlling a rotational speed of a fan includes the following steps:
step 201: when first operation aiming at a display control module is obtained, determining a speed regulation mode of a fan speed regulation module according to the first operation; and gating the speed regulation range of the fan speed regulation module according to the speed regulation mode.
Here, the main function of the fan is to dissipate heat, that is, to cool the entire device by blowing air to the main working components such as the circuit board and the coil panel.
In the embodiment of the present invention, the first operation is: the user operates keys on a display panel corresponding to the display control module, and the display panel includes various function keys, a switch key, and a pause key. The user can trigger a first operation on the display panel, so that the display control module obtains a control signal corresponding to the first operation. In the above scheme, the keys on the display panel may be physical keys or virtual display keys.
In one embodiment, the determining a speed regulation mode of the fan speed regulation module according to the first operation includes: when the first operation is a function selection operation, determining function power consumption corresponding to the function selection operation; when the functional power consumption is less than or equal to a preset power consumption threshold value, determining that the speed regulation mode of the fan speed regulation module is a full-gear mode; and when the functional power consumption is larger than a preset power consumption threshold value, determining that the speed regulation mode of the fan speed regulation module is a gear limiting mode, wherein the speed regulation range corresponding to the full gear mode is larger than the speed regulation range corresponding to the gear limiting mode.
In this embodiment, when the first operation is a function selection operation, before determining the rotation speed of the air outlet machine, acquiring temperature data monitored for a target device; judging whether the temperature data is less than or equal to a preset temperature threshold value or not; when the temperature data is less than or equal to a preset temperature threshold value, determining that the effective speed range of the fan speed regulating module is a first speed range; and when the temperature data is larger than a preset temperature threshold value, determining that the effective speed range of the fan speed regulation module is a second speed range, wherein the first speed range comprises the second speed range.
In another embodiment, the determining a speed regulation mode of the fan speed regulation module according to the first operation includes: and when the first operation is pause or closing operation, determining that the speed regulation mode of the fan speed regulation module is a full-gear mode.
Step 202: obtaining a second operation for the fan speed regulation module, the second operation being for selecting a speed for the fan within the speed regulation range.
Step 203: and determining the rotating speed of the air outlet machine and controlling the fan to rotate according to the rotating speed according to the second operation.
When the first operation is a function selection operation, determining a rotation speed to be selected corresponding to the second operation; when the temperature data is less than or equal to a preset temperature threshold value, taking the rotation speed to be selected as the rotation speed of the fan; when the temperature data is larger than a preset temperature threshold value, judging whether the rotating speed to be selected is within the second speed range; and when the rotating speed to be selected is not in the second speed range, taking a preset rotating speed higher than the rotating speed to be selected as the rotating speed of the fan.
In one embodiment, when the temperature data is greater than a preset temperature threshold, a warning light is turned on to prompt a user to select a rotating speed within the second speed range.
In the embodiment of the invention, according to the rotating speed of the fan, a PWM regulation ratio corresponding to the rotating speed is selected; and controlling the fan to rotate according to the rotating speed based on the PWM regulation ratio.
For this purpose, the corresponding relation between the rotating speed and the PWM regulation ratio is predetermined; and selecting the PWM regulation ratio corresponding to the rotating speed according to the corresponding relation between the rotating speed and the PWM regulation ratio.
In the above technical solution of the embodiment of the present invention, the operating state of the device is divided into two operating modes, and when the first operation is a function selection operation, the first operation corresponds to the function selection mode; when the first operation is a pause or close operation, a pause or close state mode is corresponded.
For the function selection mode: the premise of adjusting the rotating speed of the fan is that the current temperature of the target device is within a controllable range, the temperature monitoring module of the target device is monitored in real time after being started, and if the temperature is higher and exceeds the controllable range, the low-speed gear selection is invalid, and only the high-speed gear selection can be carried out. The full gear selection can be performed only after the temperature is reduced. If the temperature of the device gradually rises to exceed the controllable range in the working process, the warning lamp is turned on and automatically jumps to the lowest-level high-speed gear for cooling.
For example: starting up the machine to work in a cold machine state, and when low-power work or a heat preservation function is selected, the heat productivity of each device is low, the integral temperature of the equipment is low, and the fan speed regulation module is in a full gear mode and can be selected from the lowest gear to the highest gear; when high-power work or oil functions are selected, the temperature rises quickly, the heat productivity of each device is large, the overall temperature of the equipment is high, the fan speed regulating module is in a gear limiting mode, and the rotating speed can be selected only in the range from a high-speed gear to a full-speed gear.
For the suspended or off state mode: the device is not heated any more, and the temperature of each device is gradually reduced, and the temperature reduction can be accelerated at any rotating speed. Therefore, the fan speed regulating module is not limited in rotating speed, the full-gear mode is directly started, and a user can select the rotating speed of the fan suitable for the user to cool.

If the temperature data is in the controllable range, the gear information of the fan speed regulation module is effective and is in a full gear mode; and if the temperature data exceeds the controllable range, selecting a limited effective gear, wherein only the selection in the high-gear range is effective, and the warning lamp is lighted to remind the user. The display control module transmits the gear information to the main control module, the main control module calculates the rotating speed according to the gear information, confirms the regulation ratio and controls the fan to regulate the rotating speed of the selected gear in a PWM mode. Here, a plurality of rotation speed values can be determined in a low-speed, medium-speed and high-speed range in advance as gear selection, a corresponding regulation and control ratio is confirmed through experiments, and a corresponding relation is established between the regulation and control ratio and a gear signal transmitted by the display control module, so that the whole control process is realized.
