The wind pressure is monitored by the wind pressure monitoring module 4, and then the wind pressure is converted into dust density, so that the running environment of the server is monitored. However, the method of converting the wind pressure into the dust density has low accuracy and is also affected by fans of different models, so that the monitoring of the operating environment of the server cannot be accurately realized.
In summary, how to accurately monitor the operating environment of the server is a technical problem that needs to be solved urgently by those skilled in the art.

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a monitoring system of a server operating environment according to the present invention, the monitoring system of the server operating environment may include:
and a light source circuit 10 disposed on a fan plate of the server for providing incident light.
And the photosensitive module 20 is arranged on a fan plate of the server and used for detecting the illumination intensity of the incident light after passing through the preset area and outputting an electric signal with corresponding magnitude.
The specific circuit configuration of the light source circuit 10 and the light sensing module 20 may be set and adjusted according to actual conditions, and the purpose of the present application may be achieved, for example, the circuit setting and adjustment of the light source circuit 10 and the light sensing module 20 of the present application may be performed with reference to an internal circuit of a dust light sensor.
For example, fig. 3 shows a light source circuit 10 which has a simpler circuit structure and is convenient for the application, in fig. 3, 5V dc is output to the led D1 to obtain the incident light required by the application, and the resistor R1 is used to protect the circuit.
The light sensing module 20 needs to detect the illumination intensity of the incident light after passing through the preset area, and output an electrical signal with a corresponding magnitude. As described above, the specific circuit for converting the optical signal into the electrical signal can be set according to the requirement, for example, a circuit formed by a photodiode, and in practical applications, the current and voltage levels after the photoelectric conversion by the photoelectric conversion device may not meet the requirement of the controller 30, so the photosensitive module 20 usually includes an amplifying circuit.
Based on the principle of the dust light sensor, after the incident light provided by the light source circuit 10 passes through the preset area, the urine and the feces of the electrical signal output by the light sensing module 20 can reflect the dust density of the preset area. And it is understood that the predetermined area should not receive other light sources than the incident light provided by the light source circuit 10, such as a dust light sensor, and a black-shielding case is provided therein.
The dust light sensor is considered to be large in the application, the server shell cannot be placed in the server shell, but the server shell is internally provided with the darkroom, so that the light source circuit 10 and the photosensitive module 20 are arranged on the fan plate inside the server shell, an additional light source cannot be introduced, and the dust light sensor can be applied to the application.
Further, when the principle of the dust light sensor is applied, dust needs to be lifted, and a fan structure is generally arranged in the dust light sensor. In the scheme of this application, consider that the server is inside to have the fan, consequently set up light source circuit 10 and photosensitive module 20 on the fan board, alright blast air in order to utilize original fan on the server fan board, raise the dust granule, and then alright carry out the detection of dust density through the scheme of this application.
And a controller 30 connected to the photosensitive module 20 for determining the dust density of the predetermined area according to the acquired electrical signal.
The controller 30 may store a correspondence relationship between the magnitude of the electric signal and the dust density in advance, and the correspondence relationship may be verified and adjusted in advance through theoretical analysis and in combination with experimental data. For example, after the circuit configuration and the specific device model of each component are determined, tests may be performed at different dust densities, corresponding electrical signal magnitudes output by the photosensitive module 20 are recorded, a relationship curve between the dust density and the electrical signal magnitude is generated in a fitting manner, or a correspondence relationship between different dust densities and electrical signal magnitudes is stored in a list manner.

Thus, when incident light enters the field of particles being measured, the light intensity will be attenuated, subject to scattering and absorption around the particles. Therefore, the relative attenuation rate of the incident light passing through the density field to be measured can be obtained. And the relative attenuation rate is substantially linear in magnitude to reflect the dust density of the density field to be measured. And the intensity of the light intensity is in direct proportion to the intensity of the electric signal after photoelectric conversion, namely, the corresponding more accurate dust density can be obtained by detecting the excrement and urine of the electric signal.
Further, considering that the volume of the dust light sensor is large, the dust light sensor cannot be directly applied to a server. This application considers again, the server is inside originally exactly to be the darkroom, need not to set up the shading part to can directly utilize original fan in the server to blast air, consequently, this application has arranged light source circuit 10 and has been used for detecting the incident light and pass the illumination intensity after predetermineeing the region on the fan board of server, and the sensitization module 20 of the signal of telecommunication of output corresponding size, and then controller 30 alright confirm the dust density of predetermineeing the region according to the signal of telecommunication of acquireing. Therefore, the scheme of the application ingeniously utilizes the original structure inside the server, so that the scheme of the application can accurately monitor the operating environment of the server based on the principle of the dust light sensor.
In the present application, the specific type of the Controller 30 may also be set and selected as needed, and further, considering that the cost of separately configuring the Controller 30 is high, a BMC (Baseboard Management Controller) may be adopted as the Controller 30 of the present application, which is beneficial to reducing the cost.
When the BMC is adopted, considering that the BMC can receive signals in the PMW form and some types of dust photo-sensors can output signals in the PWM form, the light sensing part of such dust photo-sensors can be referred to for circuit design of the photo-sensing module 20 of the present application, so that conversion of communication signal types is not required, and implementation of the scheme is facilitated. That is, in this embodiment, the electrical signal output by the light sensing module 20 may be a PWM electrical signal, and the output terminal of the light sensing module 20 may be directly connected to the BMC _ SENSOR _ PWM pin of the BMC.
Further, referring to fig. 4, the light source circuit 10 and the light sensing module 20 are powered by a dc power supply on the fan plate, so that there is no need to additionally configure a power supply for the light source circuit 10 and the light sensing module 20.
