Example 1
The embodiment provides a method for regulating and controlling power supply of a fan, as shown in fig. 1 and fig. 2, comprising the following steps:
it should be noted that, in the present embodiment, the server is applied, and in the prior art, in order to uniformly plan the operation of the server, the fans and the fan sets in the server are controlled by the CPLD; and its control mode is the incessant power supply of continuity, and this kind of mode is comparatively simple, but is very big to the consumption of electric energy and natural energy, though can reach radiating effect, but will make server running cost increase at last, can't reach optimal radiating effect, and this embodiment has solved to above-mentioned problem:
s100, adding a corresponding power supply control link for each fan in the server, changing the original unified power supply strategy, and providing a technical basis for independently controlling the power supply condition of the fan; carrying out inertia test on the fan to obtain the relative inertia force of the fan; calculating the inertial rotation time of the fan through relative inertial force according to relevant knowledge of aerodynamics; performing wind power test on the fan to obtain an effective heat dissipation range (namely, a heat dissipation range) of the fan, and acquiring the arrangement condition (namely, first arrangement information) of the fan on the server;
it should be noted that, in this embodiment, the power supply control link is finally controlled by the CPLD, and the CPLD is not limited, and may also use a controller such as a BMC or a microprocessor chip to perform power supply regulation; meanwhile, an independent control link is added only as an implementation mode, and the same effect can be realized by setting a CPLD or a BMC to independently send control signals to each fan;
it should be noted that, in this embodiment, the inertia test is to adjust the fan to the same rotation speed as the normal specification, and after a certain time, the power supply of the fan is stopped, and at this time, the fan will continue to rotate due to its own inertia; the relative inertia force of the fan at the moment is obtained through serial port information of the fan and a related program of a control end, and the inertial rotation time of the fan can be accurately calculated according to the mass and the relative inertia force of the fan and related knowledge of aerodynamics; in this step, a program can also be set through the serial port, timing is carried out when the power supply of the fan is stopped, and the timing is stopped when the fan is detected to be inactive, wherein the obtained time is the inertial rotation time of the fan.
It should be noted that, in this embodiment, each server has a corresponding fan arrangement layout diagram; obtaining the arrangement condition of the fans according to the layout diagram; the fan is subjected to wind power test, namely the fan is adjusted to the rotating speed which is the same as the normal specified rotating speed, and at the moment, the maximum range reached by the airflow generated by the rotation of the fan can be sensed through the wind flow sensor, and the maximum range is the effective heat dissipation range of the fan.
S200, after the initialization configuration step is completed, the server is put into use, detection time periods and temperature intervals are set, first serial port temperature sensing information (namely first temperature information) of the server is obtained every detection time period, and the occurrence condition of a thermal event (namely the thermal event condition) is judged according to the first serial port temperature sensing information and the temperature intervals;
step S200 specifically includes:
s210, comparing the first serial port temperature sensing information with a temperature interval;
s220, if the first serial port temperature sensing information is in the temperature interval, judging that a thermal event occurs (namely, a thermal event exists);
s230, if the first serial port temperature sensing information is not in the temperature interval, judging that no thermal event occurs (namely, no thermal event exists);
it should be noted that, in this embodiment, the defined first serial port temperature sensing information is real-time temperature information of the server acquired through a serial port temperature sensor on the server, and the first serial port temperature sensing information is only used as an expression manner and an implementation manner, and is not limited at all. There are various corresponding temperature detection methods, for example: a temperature sensing element can be added in the server, and temperature information can be directly output through the connection between the element and the control end; or the temperature indicator can be installed on the server, the detection robot is configured, and the robot is controlled to check the information of the temperature indicator every detection time period.
S300, when judging that no thermal event occurs, setting power supply interval time of the fan based on inertial rotation time of the fan; executing corresponding intermittent fan power supply measures according to the power supply interval time;
step S300 specifically includes:
s310, setting the working time of the fan according to the power supply interval time;
s320, setting the scanning power supply time and the power supply sequence of the fan according to the working time and the power supply interval time of the fan;
s330, sequentially controlling the power supply conditions of the fans corresponding to the scanning power supply time and the power supply interval time according to the power supply sequence;
it should be noted that, in this embodiment, the power supply interval time of each fan is smaller than and should be infinitely close to its inertial rotation time, so that the natural resource utilization of the fan can be maximized, and if there are many fan sets or there are many servers, the electric energy is greatly saved.
It should be noted that the power supply intervals of the fans with different specifications are different, and because each fan needs to achieve the same heat dissipation effect, i.e. the same fan operating time, different scanning power supply times can be set for each fan according to the power supply intervals; setting a power supply sequence corresponding to each fan according to the scanning power supply time and the power supply interval time corresponding to each fan; for example: an existing fan A, a fan B and a fan C; the power supply interval time of the fan A is 1s, the power supply interval time of the fan B is 2s, and the power supply interval time of the fan C is 3s; if the required working time of the fan is 10s, the scanning power supply time of the fan A can be set to be 9s, the scanning power supply time of the fan B can be set to be 8s, and the scanning power supply time of the fan c can be set to be 7s; the same heat dissipation effect is achieved by the inertia of the fan and the corresponding different scanning power supply time under the condition of fully utilizing resources; the corresponding power supplying sequence is sequential power supplying, and the power supplying sequence only represents sequential execution because the reached working time is the same, and the power supplying of one fan is sequentially controlled in this embodiment, which is only an implementation manner, and the same principle can be sequentially and simultaneously controlled by two, three or four fans, etc.
S400, when the thermal event is judged to occur, setting a heat dissipation support range of each fan according to the arrangement condition of the fans and the effective heat dissipation range of the fans; executing corresponding processing measures on the thermal event according to the heat dissipation support range;
step S400 specifically includes:
s410, acquiring the existing temperature information (namely, second temperature information) of each firmware device in the server and the configuration condition (namely, second configuration information) of the server device;
s420, generating a thermodynamic diagram related to the thermal event of the server according to the existing temperature information and the server equipment arrangement condition;
s430, setting Yan Sedu, identifying a heat gathering area in the thermodynamic diagram according to the color degree, and determining a fan arrangement area according to the arrangement conditions of the heat gathering area and the fans; setting the fans in the fan arrangement area as cooling fans;
s440, setting first power supply time (namely first heat dissipation time), and supplying power to the heat dissipation fan according to the first power supply time; timing to generate first time, and obtaining second serial port temperature sensing information (namely third temperature information) of the server again when the first time reaches first power supply time;
s450, comparing the temperature sensing information of the second serial port with the temperature range;
step S450 specifically includes:
s451, if the second serial port temperature sensing information is not in the temperature range, judging that no thermal event occurs, and generating a first thermal event log corresponding to the cooling fan;
s452, if the second serial port temperature sensing information is in the temperature range, setting a second power supply time (i.e. a second heat dissipation time), and executing a heat dissipation support policy: supplying power to a heat dissipation fan and a fan located within a heat dissipation support range (i.e., a first heat dissipation support range) of the heat dissipation fan according to a second power supply time, modifying the first thermal event log, and generating a second thermal event log corresponding to the fan located within the adjacent support range;
s453, similarly to step S440, when power is supplied to the fan according to the second power supply time, timing again to generate a second time, and when the second time reaches the second power supply time, acquiring the third serial port temperature sensing information (i.e., fourth temperature information) of the server again; if the third serial port temperature sensing information is in the temperature interval, sending alarm information to a server: a part of the server corresponding to the hot aggregation area is in a high-temperature state for a long time, and a high-temperature fault may occur; and if the third serial port temperature sensing information is not in the temperature interval, judging that no thermal event occurs.
In this embodiment, the heat dissipation supporting range around the fan can be set according to the layout drawing and the effective heat dissipation range of the fan; when the fan in the heat dissipation support range is started, the generated airflow can support the heat dissipation of the fan belonging to the adjacent support range.
It should be noted that, according to the relevant steps of the visualization process, the existing temperature information and the arrangement condition of each firmware device in the server may be integrated to generate a flattened layout thermodynamic diagram; correspondingly setting Yan Sedu of a high-heat part according to the existing temperature information, and comparing the color on the thermodynamic diagram with Yan Sedu to distinguish a matched color, wherein the set part of the matched color is a heat accumulation area, equipment in the heat accumulation area is in a high-heat-generation source and needs to be subjected to high-efficiency high-quality heat dissipation treatment; therefore, in the arrangement condition of the fans, a relatively matched position is selected according to the position of the heat accumulation area in the thermodynamic diagram, the position is the fan arrangement area, the fans positioned in the fan arrangement area are cooling fans, the cooling effect can be generated on the heat accumulation area, and after the cooling fans are selected, corresponding measures are executed according to power supply time to process the heat event.
It should be noted that, in the thermal event log, the number of the fan, the component code, the number of times of the fan processing the thermal event, and whether the current fan is in a power supply state or a non-power supply state need to be acquired; if the fan is in a power supply state, the power supply time and the power supply interval of the fan are also required to be recorded; the times of the fan for processing the thermal events are accumulated according to the generation of each thermal event; in subsequent analysis and maintenance, the high-probability occurrence position of the thermal event in the server can be analyzed through the number of times that the thermal event is processed by the fan and the arrangement condition of the current fan.
By the fan power supply regulation and control method described in the embodiment, the fan can be regulated and controlled in a targeted manner for the overheating event in the server, so that the overheating event is effectively solved, and reasonable utilization of the fan resources is guaranteed; when the server does not have an overheating event, the scanning type fan power supply measure in the method enables the fan in the server to achieve a stable heat dissipation effect, natural resources of the server are not lost, heat dissipation benefits of the server are maximized, operation cost of the server is reduced, and the low-carbon and environment-friendly concept of current scientific and technological development is met.
