Description

Technical Field

[0001] This application relates to the technical field of air conditioning testing, and more specifically, to a method, apparatus, electronic device, and medium for detecting the direction of rotation of an air conditioning system fan. Background Technology

[0002] During the mainboard function testing of the air conditioning system, it is necessary to perform DCT (Direct Current Test) and fan rotation tests on the mainboard. The normal fan rotation of the air conditioning system should be forward. If the fan rotation is reverse, it means that the fan rotation of the air conditioning system is abnormal.

[0003] Since DCT testing can only verify the power-on status of the air conditioning system's fans and cannot identify the fan rotation direction, the current method for identifying the fan rotation direction is mainly based on visual inspection by staff. However, this visual inspection method is easily affected by factors such as lighting, staff fatigue, and fan speed, resulting in a high error rate. Furthermore, it is time-consuming and difficult to match a fast testing pace. If an air conditioning system with abnormal fan rotation is included in the final assembly stage, it will cause quality problems in the air conditioning system, leading to rework after assembly. It may even cause performance failures such as insufficient airflow and abnormal noise, affecting user experience and increasing after-sales costs. Summary of the Invention

Detailed Implementation

[0018] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] During the functional testing of the air conditioning system's mainboard, it is necessary to perform DCT (Direct Current Test) tests and checks for abnormal fan rotation. The air conditioning system's fan should normally rotate in the forward direction; if it rotates in the reverse direction, the fan rotation is abnormal. Since the DCT test can only verify the power-on status of the air conditioning system's fan and cannot identify its rotation direction, the current method for identifying the fan rotation direction is primarily visual inspection by personnel. However, this visual inspection method is easily affected by factors such as lighting, personnel fatigue, and fan speed, resulting in a high error rate. Furthermore, it is time-consuming and difficult to match with a fast-paced testing environment.

[0020] To address the problems in the prior art, this application provides a method, device, electronic device, and medium for detecting the fan rotation direction of an air conditioning system. This method can be applied to the mainboard function testing of air conditioning systems, accurately detecting and determining the fan rotation direction with a high speed, significantly improving testing efficiency, matching the fast-paced testing rhythm, and thus effectively avoiding quality problems caused by abnormal fan rotation in air conditioning systems, improving user experience, and reducing corresponding after-sales costs.

[0021] Example 1 See Figure 1 , Figure 1 This is a schematic diagram of the first process of the air conditioning system fan rotation detection method provided in the embodiments of this application.

[0022] The air conditioning system fan rotation detection method described in this application embodiment can be applied to computer equipment that performs functional testing in conjunction with the motherboard of the air conditioning system, such as a test host for the motherboard of the air conditioning system.

[0023] This application provides a method for detecting the direction of rotation of an air conditioning system fan, comprising the following steps: Step S110: When the motor of the air conditioning system fan is running, detect the direction of the magnetic field generated by the magnet.

[0024] In this embodiment, when applying the method for detecting the direction of rotation of the air conditioning system fan, a magnet needs to be installed on the shaft of the air conditioning system fan motor. As an optional implementation, the magnet installed on the shaft of the air conditioning system fan motor is a strong magnet. A strong magnet usually refers to a magnetic field with a magnetic field strength exceeding 1000 Gauss (i.e., 1000GS). A strong magnet is a magnet that can generate a magnetic field strength exceeding 1000GS, such as a neodymium iron boron (NdFeB) permanent magnet. Using a strong magnet on the shaft of the air conditioning system fan motor can increase the amplitude of the magnetic field signal, thereby facilitating the detection of the direction of the magnetic field generated by the magnet. This can improve the accuracy of detecting the direction of rotation of the air conditioning system fan and reduce the false positive and false negative rates. After testing, using a magnet with a weak magnetic field strength, the magnetic field signal is <10mV, which is not conducive to detecting the direction of the magnetic field generated by the magnet.

[0025] Specifically, in this embodiment, the magnetic field strength of the magnet installed on the motor shaft of the air conditioning system fan is greater than or equal to 3000GS. Preferably, the magnet installed on the motor shaft of the air conditioning system fan can be a φ8mm neodymium iron boron magnet or a φ10mm neodymium iron boron magnet. The magnetic field strength of the φ10mm neodymium iron boron magnet can reach 8500GS. The φ10mm neodymium iron boron magnet can increase the magnetic field signal amplitude to 50mV-80mV, which makes it very convenient to detect the direction of the magnetic field generated by the magnet. This can significantly improve the accuracy of detecting the direction of the air conditioning system fan. After testing, using a φ10mm neodymium iron boron magnet, the false positive rate and false negative rate of detecting the direction of the air conditioning system fan can be reduced to less than 0.1%, which greatly ensures the accuracy of detecting the direction of the air conditioning system fan.

[0026] Understandably, when the motor of the air conditioning system fan is running, that is, when the motor shaft of the air conditioning system fan rotates, the direction of the magnetic field generated by the detected magnet can be divided into magnetic field direction NS and magnetic field direction SN.

[0027] Step S120: Output the corresponding electrical signal according to the direction of the magnetic field generated by the magnet.

[0028] In this embodiment, the output electrical signal is different when the magnetic field generated by the magnet is in the direction of NS. That is, the output electrical signal is different when the magnetic field generated by the magnet is in the direction of SN. Thus, the direction of the magnetic field generated by the magnet can be distinguished based on the different electrical signals, and then the direction of the motor can be determined as forward or reverse.

[0029] As an optional implementation, in this embodiment, a Hall sensor can be used to detect the direction of the magnetic field generated by the magnet when the motor of the air conditioning system fan is running, and output a corresponding electrical signal according to the direction of the magnetic field generated by the magnet; wherein, the Hall sensor is set on the air conditioning system fan and installed close to the motor of the air conditioning system fan so that the Hall sensor can detect the direction of the magnetic field generated by the magnet.

[0030] In the above process, the use of Hall effect sensors for detection can quickly and accurately determine the direction of the magnetic field generated by the magnet, which helps to improve the detection accuracy and efficiency of the air conditioning system fan rotation direction.

[0031] As an optional implementation, the distance between the Hall sensor and the motor shaft of the air conditioning system fan can be 2mm-5mm; preferably, the distance between the Hall sensor and the motor shaft of the air conditioning system fan is 3mm-4mm. After testing, when the distance between the Hall sensor and the motor shaft of the air conditioning system fan is 3mm-4mm, the noise of the magnetic field signal is ≤50mV, and the interference is minimal. This can help the Hall sensor detect the direction of the magnetic field generated by the magnet.

[0032] As an optional implementation, in practice, a shielded signal cable can be used to transmit the electrical signal transmitted by the Hall sensor, and the power line and the electrical signal line can be laid in separate channels (for example, the power line runs through a PVC cable tray, and the electrical signal runs through a metal shielded channel). This can avoid cross-interference. Furthermore, the electrical signal circuit can be optimized by designing a two-stage amplifier circuit (80dB gain) + Schmitt trigger to convert the weak electrical signal into a 5V / 0V standard level, thus solving the problem of false or missed detections caused by weak electrical signals.

[0033] Step S130: Based on the corresponding electrical signal, the rotation direction of the air conditioning system fan is detected.

[0034] In this embodiment, based on different electrical signals, it is possible to detect whether the direction of the air conditioning system fan motor is forward or reverse, and thus the direction of the air conditioning system fan can be determined. It can be understood that the direction of the air conditioning system fan motor corresponds to the direction of the air conditioning system fan; that is, if the direction of the air conditioning system fan motor is forward, then the direction of the air conditioning system fan is also forward; if the direction of the air conditioning system fan motor is reverse, then the direction of the air conditioning system fan is also reverse.

[0035] Alternatively, the detected air conditioning system fan rotation result can be displayed on a computer device used for functional testing of the air conditioning system's motherboard, or on a large display screen set up at the test site; or, the detected air conditioning system fan rotation result can be broadcast live on-site via a voice device.

[0036] The air conditioning system fan rotation detection method of this application embodiment can be applied to the mainboard function test of the air conditioning system. It can detect the direction of the magnetic field generated by a magnet installed on the motor shaft of the air conditioning system fan during operation and output a corresponding electrical signal. Based on the corresponding electrical signal, the rotation direction of the air conditioning system fan is detected. Compared with visual identification by personnel, this method is not affected by factors such as light, personnel fatigue, and speed, and can more accurately detect and determine the rotation direction of the air conditioning system fan. Furthermore, the detection rate is extremely fast, which can effectively improve detection efficiency and match the fast-paced testing rhythm. This can better prevent abnormally rotated air conditioning system fans from entering the final assembly stage of the air conditioning system, avoid quality problems caused by abnormal fan rotation, improve user experience, and reduce corresponding after-sales costs.

[0037] As an optional implementation, in this embodiment, when the direction of the magnetic field generated by the magnet is detected to be NS, the output electrical signal is a high-level-low-level digital signal according to the direction of the magnetic field generated by the magnet. When the direction of the magnetic field generated by the magnet is detected to be SN, the output electrical signal is a low-level-high-level digital signal according to the direction of the magnetic field generated by the magnet.

[0038] In the above process, by outputting a high-level-low-level digital signal or a low-level-high-level digital signal, it is easy to detect and determine the direction of rotation of the air conditioning system fan motor, and thus it is easy to detect and determine the direction of rotation of the air conditioning system fan, that is, whether it is forward or reverse rotation.

[0039] Specifically, in the above implementation, when the output electrical signal is a high-level-low-level digital signal, the direction of rotation indicating that the air conditioning system fan is rotating in the forward direction is detected; When the output electrical signal is a low-level to high-level digital signal, the direction of rotation indicating that the air conditioning system fan is reversing is detected.

[0040] See Figure 2 , Figure 2 This is a schematic diagram of the second process of the air conditioning system fan rotation detection method provided in the embodiments of this application.

[0041] As an optional implementation, this application provides a method for detecting the direction of rotation of an air conditioning system fan. After detecting the direction of rotation of the air conditioning system fan based on the corresponding electrical signal in step S130, the method may further include the following steps: Step S140: When the rotation result of the air conditioning system fan indicates that the air conditioning system fan is rotating in the forward direction, control the audible and visual alarm to light up the green light. In step S150, when the air conditioning system fan rotation result indicates that the air conditioning system fan is reversing, the sound and light alarm is controlled to light up a red light and emit an alarm sound.

[0042] Understandably, if the result of the air conditioning system fan rotation indicates that the air conditioning system fan is rotating forward, then step S140 is executed; if the result of the air conditioning system fan rotation indicates that the air conditioning system fan is rotating in reverse, then step S150 is executed. Steps S140 and S150 are mutually exclusive and can be executed only once.

[0043] In the above process, the control of the audible and visual alarm based on the rotation result of the air conditioning system fan can make it easy for testers to clearly know the rotation of the air conditioning system fan, that is, to clearly know whether the rotation of the air conditioning system fan is abnormal. When the rotation of the air conditioning system fan is abnormal, it is also easy to take corresponding measures in a timely manner, such as taking the abnormal air conditioning system fan offline and performing maintenance.

[0044] By combining the above-described various implementation methods, a preferred embodiment of the air conditioning system fan rotation detection method provided in this application can be obtained. The overall implementation logic of this preferred embodiment of the air conditioning system fan rotation detection method can be found as follows: Figure 3 The diagram shows a logic diagram of the method for detecting the fan rotation direction of an air conditioning system.
