[0007] The single-chip microcomputer is used to receive the rotating speed information of the cooling fan collected by the infrared photoelectric reflection sensor and transmit it to the upper computer; the upper computer compares the received information with the preset rotating speed threshold range of the cooling fan, and if an abnormality is found, transmits the information to the single-chip microcomputer, and the buzzer connected with the single-chip microcomputer gives an alarm, thereby achieving comprehensive monitoring of the working condition of the device cooling fan, i.e. comprehensively, intuitively and accurately mastering the state of the cooling fan.

[0018] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0019] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 As shown, a device cooling fan operation detection system includes an infrared photoelectric reflection sensor, a microcontroller, a host computer, and a buzzer. The infrared photoelectric reflection sensor and the buzzer are respectively connected to the microcontroller for communication. The microcontroller is connected to the host computer through a serial port module.

[0023] The infrared photoelectric reflection sensor is installed opposite the cooling fan, with its probe perpendicular to the fan blades. It is used to measure the speed of the cooling fan by identifying a marker that is clearly distinguishable from the color of the fan blades and is pre-set on any one of the fan blades. The collected cooling fan speed data is then sent to the microcontroller. Specifically, the infrared photoelectric reflection sensor can measure the speed by identifying the number of times the marker appears per unit time.

[0024] The microcontroller is used to receive the cooling fan speed information collected by the infrared photoelectric reflection sensor and transmit it to the host computer. The host computer compares the received information with the preset cooling fan speed threshold range. If an abnormality is found, the information is transmitted to the microcontroller, and an alarm is issued through a buzzer connected to the microcontroller. This enables comprehensive monitoring of the cooling fan's operation, that is, to achieve a comprehensive, intuitive, and accurate understanding of its status.

[0025] The infrared photoelectric reflection sensor is connected to the microcontroller using DuPont wires.

[0026] The microcontroller is connected to the host computer via a USB interface.

[0027] The infrared photoelectric reflection sensor uses the TCRT5000 infrared photoelectric reflection sensor module. This module was chosen because it has strong adaptability to ambient light. It has a pair of infrared emitting and receiving tubes. The emitting tube emits infrared light of a certain frequency. When the detection direction encounters a reflective surface (obstacle), the infrared light is reflected back and received by the receiving tube. After processing by the comparator circuit, a green indicator light illuminates, and the signal output interface outputs a digital signal (a low-level signal), thus realizing the counting (rotational speed) measurement. Therefore, the reflectivity and shape of the target are key to the detection distance. Black objects have a shorter detection distance, while white objects have a longer one; small objects have a shorter detection distance, while large objects have a longer one. Based on this working principle, simply attaching a white label to any one of the black blades of the cooling fan is sufficient to measure the rotational speed.

[0028] Furthermore, choosing an infrared photoelectric reflection sensor also has the advantages of small size, simple installation, independence from equipment, flexible layout, and low price.

[0029] The microcontroller used is the Atmega328p CH340 development board. This version was chosen because it uses a high-speed microprocessor, has a fast running speed, can achieve simultaneous acquisition of multiple channels, and has a very simple and easy-to-understand development and operating environment, making it very suitable for development.

[0030] The infrared photoelectric reflection sensor, microcontroller, host computer and buzzer modules are connected by DuPont wires to facilitate disassembly and reconfiguration, making it convenient and efficient.

[0031] The host computer is equipped with an abnormal color display, and alarms are triggered simultaneously with a buzzer.

[0032] The fan blades of the cooling fan are black, and the markings on the fan blades are white.

[0033] The infrared photoelectric reflection sensor is fixed 2-5 cm away from the cooling fan.

[0034] This utility model's equipment cooling fan operation detection system has an ingenious structure. Utilizing the working principle of an infrared photoelectric reflection sensor, it allows monitoring personnel to directly observe the cooling fan's operation in real time on a host computer without needing to go to the site. Furthermore, it is completely independent of the equipment, has a compact structure, and is easy to install. It can be used to quickly achieve comprehensive real-time monitoring of the cooling fan operation of existing equipment. Overall, it has good performance, effectively reduces the risks associated with equipment use, improves work efficiency and monitoring targeting, and has a wide range of applications. In addition, the infrared photoelectric reflection sensor itself has the advantages of small size, simple installation, independence from the equipment, flexible layout, and low cost, making it highly practical and worthy of promotion.

[0035] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
