According to an aspect of the present invention, an embodiment of the present invention provides a fan status light control method, as shown in fig. 1, which may include the steps of:
s1, detecting state information of a plurality of fans by using a first controller;
s2, regulating and controlling the single state lamp corresponding to each fan according to the detected state information;
s3, responding to an enable signal of a low level sent by the first controller to the second controller, and detecting the state of the single state lamp corresponding to each fan by using the second controller;
and S4, regulating and controlling the integral state lamps corresponding to the fans according to the detected state of the single state lamp of each fan.
According to the scheme provided by the invention, the fan states are monitored, divided and divided in authority by the first controller and the second controller, so that the efficiency of lighting the integral state lamp can be improved, meanwhile, the authority of the integral state lamp of the first control point can be adjusted to be highest because the first controller does not directly control the integral state lamp, the regulation and control of the integral fan state lamp of a production line can be realized, and the production line test is facilitated.
In some embodiments, the step S1 of detecting, by the first controller, status information of a plurality of fans further includes:
determining the in-place state of each fan according to the interrupt signal;
periodically detecting the rotating speed of each fan and determining the running state of each fan according to the rotating speed.
Specifically, as shown in fig. 2, the on-site state of the fan may be connected to a BMC (first controller) through a GPIO, and the BMC monitors the fan module in an interrupt manner. The fan monitoring method has the advantages that the fan monitoring method is connected to the BMC in a GPIO interrupt mode, timeliness of the fan monitoring in-place state of the BMC can be improved, and low timeliness caused by polling of a CPLD register is avoided.
In some embodiments, periodically detecting a rotational speed of each fan and determining an operational status of each fan based on the rotational speed, further comprises:
responding to the detected abnormal rotating speed, continuously monitoring the fan with the abnormal rotating speed, and removing the tremble of the detected rotating speed;
and judging whether the fan is abnormal or not according to the debouncing result.
Specifically, as shown in fig. 2, the BMC periodically monitors the rotational speed of the fan module. If the fan module is in place, monitoring the rotating speed information of the fan module, judging whether the rotating speed of the fan module is abnormal or not according to a preset strategy, if the detected rotating speed of the fan is abnormal, continuously monitoring the abnormal module according to a certain shaking removing principle, and outputting a lighting strategy for the local fan module and the like according to a shaking removing result.
In some embodiments, the controlling of the single status light corresponding to each fan according to the detected status information further includes;
and outputting a first control signal to light monomer status lights of corresponding colors of the fan in response to judging that the fan is in an off-position state according to the interrupt signal or judging that the running state of the fan is abnormal according to the detected rotating speed.
Specifically, as shown in fig. 2, during the normal operation of the BMC, only the single status light of the fan module is turned on. The BMC monitors the on-site and rotating speed state of the fan module and lights the fan module according to the monitoring result and the lighting strategy. Through the regulation and control of BMC, the fan local lamp keeps the latest and correct state all the time.
In some embodiments, when the BMC detects the on-position status of the fan module through the interrupt signal, the local light of the fan module is turned on to emit red light if the fan module is not on position. If the BMC detects that the fan module is in place, whether the rotating speed of a rotor of the fan module is abnormal or not is judged, if the rotating speed of the rotor of the fan module is abnormal, the BMC continuously monitors according to a shaking removing principle, and if the rotating speed of the rotor of the fan module is still abnormal, the BMC conducts red light lighting treatment on a local lamp of the fan module. And when the BMC detects that the rotating speed of the fan module is abnormally recovered, turning on a local lamp of the fan module for green operation. And when the BMC detects that the fan module is not in place, turning on a local lamp of the fan module to be green.
In some embodiments, detecting, with the second controller, a status of the single status light corresponding to each of the fans further includes:
detecting, with the second controller, a level of a pin connected to the each fan to determine a status of a cell status light.
Specifically, the single status light of each fan may be composed of two LEDs, one is a red light, and the other is a green light (only one LED is on at the same time), and the green light may be connected to the pin of the CPLD, so that the CPLD may determine whether the green LED is on or off through the high-low level of the pin.
In some embodiments, the controlling the overall status light corresponding to the plurality of fans according to the detected status of the single status light of each fan further includes:
in response to the level of a first preset number of pins being a low level, illuminating the integral status light to a first color;
in response to the level of a second preset number of pins being a low level, turning on the integral status light to a second color;
and in response to the level of all pins being high, lighting the integral status light to a third color.
Specifically, when the CPLD continuously monitors the single state lamp of the fan module, if it is detected that the single state lamp of one fan module is red, that is, the CPLD detects that the level on one pin is low, the lamp in the whole state is turned yellow; and if the single state lamp with two or more fan modules is red, namely the CPLD detects that the level on two or more pins is low, the integral state lamp is lighted red. And if the detected levels on all the pins are high levels, turning the integral state light to green.
In some embodiments, further comprising:
and in response to the first controller sending a high-level enable signal to the second controller, the second controller lights the integral status lamp with a corresponding color according to the regulation and control signal of the integral status lamp sent by the first controller.
Specifically, as shown in fig. 2, when the CPLD detects that the BMC operates the entire status lamp, the CPLD performs lighting processing in accordance with the status set by the BMC, and does not perform lighting operation in accordance with the status of the single status lamp of the fan module. That is, the BMC may open the interface to directly control the entire fan status light, and the BMC controls the entire status light with the highest authority, and if the entire status light is turned on by the BMC, the lighting state of the BMC is used as the standard.
According to the scheme provided by the invention, the fan states are monitored, divided in labor and divided in authority by the first controller and the second controller, namely, the control signal of the integral state lamp is directly connected to the CPLD, the BMC directly controls the single state lamp, and the integral state lamp of the fan is indirectly controlled by the CPLD. Not only can improve the efficiency of lighting whole state lamp, simultaneously, because the holistic state lamp of first controller indirect control, can transfer the authority of the whole state lamp of first control point to the highest, can realize producing the regulation and control of line to whole fan state lamp, be convenient for produce the line test.
