It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
Hot plugging (Hot swapping) is also called Hot swapping, i.e., "Hot plugging", which means that hardware can be plugged in or removed from a computer while the computer is running. By matching with appropriate software, the peripheral equipment supporting hot plug can be plugged in or unplugged without turning off the power supply, the host computer or the peripheral equipment can not be burnt, and new equipment can be detected and used in real time. Compared with Plug-and-Play, the requirements of hot Plug for software and hardware also include the contact sequence of power supply, signal and grounding wire.
The invention adds a permanent magnet in the structure of a fan module, takes the permanent magnet as a fixed signal emission source, transmits a magnetic signal through air magnetic lines of force on the stroke of inserting and pulling out the fan module, detects an input signal by a Hall Sensor on a mainboard, converts the electromagnetic signal into an electric signal after detecting the electromagnetic signal emitted by the permanent magnet, further converts the electric signal into an on-position signal, and turns on a fan power supply after detecting the on-position signal by a fan on-position detection signal (PRSNT #) of the mainboard so as to avoid the problem of flashover caused by the fact that a connector with long and short pins cannot be selected.
A Hall Sensor (Hall Sensor) is a Sensor that senses a change in a magnetic field based on the Hall effect. The hall sensor of the hall sensor is generally made of P-type semiconductor, such as gallium arsenide (GaAs) and indium antimonide (InSb). The Hall sensing component can obtain potential difference (voltage) after sensing the magnetic field, the potential difference is an analog signal, so that the potential difference can be conveniently input to a GPIO pin of the MCU for subsequent control, and can be converted into a high or low digital signal through an amplifier and a Schmitt trigger and finally output.
The hall sensors can be divided into four types according to sensing modes:
unipolar and one output (Unipolar and one output): only one of S pole or N pole of the magnetic field can be induced, and the signal is a single output;
bipolar single output (Bipolar and one output): the S pole or the N pole of the magnetic field can be induced, and the signal is output singly;
bipolar dual output (Bipolar and two output): the S pole or the N pole of the magnetic field can be induced, the signal is double-output, and two output pins respectively reflect the state of the S pole or the N pole;
state change detection (Biploar latch): can induce the magnetic field to change from S pole to N pole or from N pole to S pole, the signal is a single output.
Any one of the above hall sensors may be used in the embodiments of the present invention.
In view of the above objects, a first aspect of embodiments of the present invention proposes an embodiment of a method of hot-plugging a fan. Fig. 3 is a schematic diagram illustrating an embodiment of a method for hot insertion of a fan according to the present invention. As shown in fig. 3, the embodiment of the present invention includes the following steps:
s1, responding to the insertion of the fan module into the connector, and transmitting an electromagnetic signal based on the permanent magnet arranged in the fan module;
s2, responding to the received electromagnetic signals, and converting the electromagnetic signals into electric signals based on the Hall sensors on the mainboard;
s3, responding to the received electric signal, converting the electric signal into an in-place signal; and
and S4, responding to the received in-place signal, and turning on the power supply of the fan module.
Fig. 4 is a schematic diagram illustrating the connection between the fan module and the system connector according to the present invention. As shown in fig. 4, a permanent magnet is added to the fan module, and a hall sensor is used on the main board to detect an electromagnetic signal sent by the permanent magnet. When the Hall sensor detects an electromagnetic signal, high magnetic energy can be converted into an electric energy signal, and the electric energy signal is further converted into an in-place signal to start or stop a power supply. Specifically, when the BMC or other control source detects the in-place signal, the normal installation of the fan is determined, then the corresponding power control chip controls the power of the fan to be turned on, and then the rotation of the fan maintains the heat dissipation of the system.
In some embodiments, the method further comprises: and adjusting the relative distance between the permanent magnet and the Hall sensor according to the time of delayed start of the power supply. In some cases, the time for delaying the start of the power supply is different among different types of power supplies, so that the time for delaying the start of the power supply can be adjusted by adjusting the relative distance between the permanent magnet and the Hall sensor in order to meet the requirements of different power supplies. Under the unchangeable condition of hall sensor on the mainboard, can adjust the position of permanent magnet on the fan module. In addition, because the hot plug also has requirements on the time sequence, the time sequence control can be adjusted by adjusting the relative position relationship between the permanent magnet and the Hall sensor.
In some embodiments, the turning on the power of the fan module includes: and acquiring the environmental temperature information of the fan module, and adjusting the voltage of the power supply according to the environmental temperature information. The voltage can affect the speed of the fan, which is faster when the voltage is higher. When the environmental temperature of the fan module is higher, namely the heat dissipation requirement is higher, the voltage of the power supply can be increased, so that the rotating speed of the fan is increased; when the ambient temperature of the fan module is relatively low, that is, the heat dissipation requirement is relatively low, the voltage of the power supply can be reduced, so that the rotating speed of the fan is reduced.
In some embodiments, the method further comprises: responding to the simultaneous reception of a plurality of groups of in-place signals, and judging whether power supplies with the same delay starting time exist or not; and in response to the fact that the power supplies with the same delay starting time do not exist, sequencing the power supplies corresponding to each group of in-place signals from small to large according to the delay starting time of the power supplies, and sequentially starting the corresponding power supplies according to the sequencing. For example, A, B, C and D four sets of bit signals are received simultaneously, if the delay start time is 0.1 ms, 0.15 ms, 0.2 ms and 0.25 ms, respectively, then the following sequences are performed according to the delay start time from small to large: A. b, C, D are provided. And sequentially turning on corresponding power supplies according to the sequence.
In some embodiments, the method further comprises: responding to the power supplies with the same delay starting time, and judging whether the total power consumption of the power supplies with the same delay starting time is larger than a starting threshold value or not; and responding to the fact that the total power consumption of the power supplies with the same delay starting time is larger than a starting threshold value, and starting the power supplies in sequence according to the environment temperature of the power supplies. In order to avoid excessive power consumption in a moment, if the total power consumption of the power supplies with the same delay starting time is excessive, the power supplies are sequentially started according to the ambient temperature. For example, when A, B, C and D four sets of on-bit signals are received simultaneously, if the delay start time is 0.1 ms and the environmental temperatures are 23.2 ℃, 23.5 ℃, 23.7 ℃ and 24.0 ℃, respectively, the power supply can be started from high to low according to the environmental temperatures.
In some embodiments, the method further comprises: and responding to the fact that the total power consumption of the power supplies with the same delay starting time is not larger than a starting threshold value, and starting the power supplies simultaneously.
In some embodiments, said sequentially activating the power supply according to the ambient temperature of the power supply comprises: judging whether the environmental temperatures of the power supplies with the same delay starting time are the same or not; and responding to different environmental temperatures of the power supplies with the same delay starting time, and sequentially starting the power supplies according to the sequence from high environmental temperature to low environmental temperature. For example, if A, B, C and D four sets of on-position signals are received simultaneously, if the delay start time is 0.1 ms, and the environmental temperatures are 23.2 ℃, 23.5 ℃, 23.7 ℃ and 23.2 ℃, respectively, it is first determined whether the environmental temperatures are the same, the environmental temperatures of a and D are the same, and AD and B, C are different, and C, B, A (D) is sequentially performed according to the sequence of the environmental temperatures from high to low. The power supplies with different ambient temperatures are sequentially started from high to low according to the ambient temperatures, when the ambient temperatures are the same, whether the total power consumption of the power supplies is larger than a preset threshold value or not is judged, if the total power consumption of the power supplies is not larger than the threshold value, all the power supplies can be started simultaneously, and if the total power consumption of the power supplies is larger than the threshold value, the power supplies with the same ambient temperatures can be started in a random starting mode.
In order to clearly illustrate the overall concept of the present invention, the following description will be made by taking an example:
a permanent magnet is additionally arranged in each fan module according to the delayed starting time of a power supply, and the position of the permanent magnet is determined by the Hall sensor and the delayed starting time together. When the fan module is inserted into the connector, one or more Hall sensors on the main board can detect electromagnetic signals, the Hall sensors can convert the electromagnetic signals into electric signals and finally convert the electric signals into in-place signals, and the system detects the in-place signals and then turns on a power supply of the fan module. At the moment, the environmental temperature information of the fan module can be acquired, the output voltage of the power supply can be increased when the environmental temperature information is higher than a preset threshold value, and the output voltage of the power supply can be reduced when the environmental temperature information is lower than the preset threshold value. It is also possible to set a proportional function of the voltage and the ambient temperature and set the output voltage of the power supply according to the function.
If there are simultaneous on-position signals received from multiple fan modules, for example, A, B, C, D are four groups of on-position signals respectively, the delayed start time is 0.1 ms, 0.15 ms, 0.2 ms and 0.1 ms respectively, and the environmental temperature is 23.1 ℃, 23.3 ℃, 23.1 ℃ and 23.7 ℃ respectively. Firstly, four groups of bit signals are arranged from small to small according to the delay starting time, and are sorted as follows: a (D), B, C, the delay start time of A and D are both 0.1 ms, so their sequence positions are the same. And then, determining the total power consumption of A and D according to the environment temperature of A and D, if the total power consumption of A and D is greater than a preset threshold value, determining the starting sequence of A and D according to the environment temperature from large to small, and if the total power consumption of A and D is not greater than the preset threshold value, starting the power supplies corresponding to A and D at the same time. That is, if the total power consumption of a and D is greater than the preset threshold, the start-up sequence is as follows: D. a, B, C, respectively; if the total power consumption of A and D is not greater than the preset threshold, the starting sequence is as follows: a (D), B, C.
