[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0026] In order to keep the following description of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components. Next, the power supply device for electronic equipment provided by the present invention is specifically described.

[0027] Figure 1 A schematic diagram of the structure of a detection device provided by an embodiment of the utility model is shown. Figure 1It can be seen that the detection device includes a connection component 1, a printed circuit board 2, a detection component 3 and a controller 4. The detection component 3 and the controller 4 are electrically connected to the printed circuit board 2. The detection component 3 includes photoresistors corresponding to the target objects to be detected, and the photoresistors correspond to light transmission channels. Optionally, the controller 4 can be set as a control chip, as long as it has the functions of receiving data, storing data, sending data, etc. The controller 4 can be installed on the printed circuit board 2. The size of the printed circuit board 2 can be as long as it can carry the controller 4 and the area that can be electrically connected to the detection component 3. The embodiment of the present application does not make specific restrictions on this.

[0028] When the connection component 1 meets the preset conditions, the photoresistors of the detection component 3 are used to sense the state changes of the corresponding target objects through the corresponding optical transmission channels to generate detection data and transmit the detection data to the controller 4. When the connection component 1 meets the preset conditions, the connection component 1 is connected to the network port to be tested to which the target object belongs. That is to say, as long as the connection component 1 is connected to the network port to be tested to which the target object belongs, it indicates that the connection component 1 meets the preset conditions. In a specific implementation, the connection component 1 meets the preset conditions, which indicates that the network port to be tested has started to be detected.

[0029] Figure 2 An exploded view of a detection device provided by an embodiment of the utility model is shown, referring to Figure 2 It can be seen that the detection component 3 includes a first photoresistor 31 and a second photoresistor 32 , which respectively collect light signals of corresponding target objects, that is, the first photoresistor 31 and the second photoresistor 32 correspond to different target objects.

[0030] The target object in the embodiment of the utility model is the network port indicator light. Figure 1 It can be seen that the position of the first photoresistor 31 and the position of the corresponding network port indicator light meet the optical signal collection conditions, that is, the position of the first photoresistor 31 can satisfy that it only collects the optical signal of the corresponding network port indicator light; similarly, the position of the second photoresistor 32 and the position of the corresponding network port indicator light meet the optical signal collection conditions, that is, the position of the second photoresistor 32 can satisfy that it only collects the optical signal of the corresponding network port indicator light.

[0031] It is worth noting that the number of photoresistors included in the detection component 3 is determined by the number of network port indicator lights to be detected. In the embodiment of the utility model, two network port indicator lights are provided on the network port to be tested. Therefore, the embodiment of the utility model sets the detection component 3 to include a first photoresistor 31 and a second photoresistor 32, as long as the number of photoresistors is the same as the number of network port indicator lights to be detected.

[0032] The detection device of the embodiment of the utility model further includes a light shielding component 5, which is used to shield the light generated by other objects except the target object from being transmitted to the first photoresistor 31 and the second photoresistor 32. Optionally, the light shielding component 5 is a dark object, which can ensure that the first photoresistor 31 and the second photoresistor 32 are not affected by the light generated by other objects, thereby ensuring the accuracy of the detection result of the target object.

[0033] Preferably, the shading component 5 is elastic, for example, the shading component 5 is made of black foam. The shading component 5 can be arranged to wrap the first photoresistor 31, the second photoresistor 32, the connecting component 1, the printed circuit board 2 and the controller 4 inside thereof to prevent the first photoresistor 31, the second photoresistor 32, the connecting component 1, the printed circuit board 2 and the controller 4 from being damaged by accidental external touches. In addition, the shading component 5 is elastic and can be applied to first photoresistors 31, second photoresistors 32, connecting components 1, printed circuit boards 2 and controllers 4 of different specifications, and of course, can also be applied to photoresistors of different numbers, which effectively improves the configuration flexibility and layout flexibility of each component.

[0034] It is worth noting that a light transmission channel needs to be provided in the shading component 5 to ensure that the first photoresistor 31 and the second photoresistor 32 can collect light signals of their respective target objects, and each photoresistor uniquely corresponds to one light transmission channel.

[0035] The first photoresistor 31 and the second photoresistor 32 are respectively connected to the general-purpose input / output (GPIO) pins of the controller 4. In the actual detection process, when the connection component 1 senses the state change of the target object after satisfying the preset conditions, the first photoresistor 31 senses the corresponding network port indicator light, that is, collects the light signal generated by the network port indicator light, and then the first photoresistor 31 converts the collected light signal into a first electrical signal; similarly, the first photoresistor 31 senses the corresponding network port indicator light, that is, collects the light signal generated by the network port indicator light, and then the second photoresistor 32 converts the collected light signal into a second electrical signal. The first electrical signal includes the first voltage of the first photoresistor 31, and the second electrical signal includes the second voltage of the second photoresistor 32.

[0036] Continue to refer to Figure 1 and Figure 2The first photoresistor 31 and the second photoresistor 32 are both electrically connected to the printed circuit board 2. During the actual detection process, the controller 4 is used to monitor the first electrical signal of the first photoresistor 31 and the second electrical signal of the second photoresistor 32, that is, the controller 4 monitors the first voltage of the first photoresistor 31 and the second voltage of the second photoresistor 32 in real time.

[0037] In a specific implementation, when the photoresistor senses that the indicator light changes from off to on, the voltage across the photoresistor decreases; when the photoresistor senses that the indicator light changes from on to off, the voltage across the photoresistor increases. Based on this, the detection data in the embodiment of the utility model includes the first voltage and the second voltage corresponding to each detection time point in the detection time period, and then it can be judged whether the target object corresponding to the first photoresistor 31 is operating normally according to the first voltage corresponding to multiple consecutive detection time points, and similarly, it can be judged whether the target object corresponding to the second photoresistor 32 is operating normally according to the second voltage corresponding to multiple consecutive detection time points.

[0038] Optionally, a connection portion 21 is provided on the printed circuit board 2, and the connection portion 21 and its corresponding connecting line connect the controller 4 and the detection device, and the detection device is used to run the detection program and obtain the detection result according to the detection data. On this basis, the controller 4 converts the detection data into a data format corresponding to the connecting line, and transmits the converted detection data to the detection device. For example, when the connecting line is a universal serial bus (USB), the detection data is converted into a data format that complies with the USB transmission protocol to ensure that the detection data is transmitted to the detection device.

[0039] After receiving the detection data transmitted by the controller 4, the detection device analyzes and processes the detection data to obtain the detection result, that is, to determine whether the target object is normal. For example, the network port to be tested is provided with a network port indicator light A and a network port indicator light B, and when the network port to be tested is in operation, the network port indicator light A is in a lit state, and the network port indicator light B is in an extinguished state; when the network port to be tested is in operation and data transmission is generated, the network port indicator light A is in a lit state, and the network port indicator light B is in an alternating state of lighting and extinguishing.

[0040] Based on this, after the connection component 1 is connected to the network port to be tested, the first photoresistor 31 senses the state change of the network port indicator light A, and transmits the first voltage corresponding to each detection time point in the detection time period to the controller 4. Similarly, the second photoresistor 32 senses the state change of the network port indicator light A, and transmits the second voltage corresponding to each detection time point in the detection time period to the controller 4. The controller 4 transmits the first voltage and the second voltage in the detection time period to the detection device, and the detection device analyzes the first voltage in the detection time period. If the voltage value of the first voltage is reduced from voltage 1 to voltage 2, and voltage 2 is maintained, it indicates that the network port indicator light A is normal; if the voltage value of the first voltage is other changes, it indicates that the network port indicator light A is abnormal. At the same time, the detection device analyzes the second voltage in the detection time period. If the voltage value of the second voltage is maintained at voltage 1, it indicates that the network port indicator light B is normal. Among them, the detection time period can be the moment when the connection component 1 is connected to the network port to be tested to the current moment.

[0041] In the scenario where the connection component 1 is connected to the network port to be tested and data is transmitted, from the moment when the connection component 1 is connected to the network port to be tested, the first photoresistor 31 senses the state change of the network port indicator light A, and transmits the first voltage corresponding to each detection time point in the detection time period to the controller 4. Similarly, the second photoresistor 32 senses the state change of the network port indicator light A, and transmits the second voltage corresponding to each detection time point in the detection time period to the controller 4. The controller 4 transmits the first voltage and the second voltage in the detection time period to the detection device, and the detection device analyzes the first voltage in the detection time period. If the voltage value of the first voltage is reduced from voltage 1 to voltage 2 and remains at voltage 2, it indicates that the network port indicator light A is normal; otherwise, it indicates that the network port indicator light A is abnormal. At the same time, the detection device analyzes the second voltage in the detection time period. If the voltage value of the second voltage remains at voltage 1 before data transmission, and the voltage value of the second voltage after data transmission is alternating between voltage 1 and voltage 2, then it indicates that the network port indicator light B is normal; otherwise, it indicates that the network port indicator light B is abnormal. Among them, the detection time period can be from the moment when the connection component 1 is connected to the network port to be tested to the current moment.

[0042] The embodiment of the utility model utilizes a detection component to sense the state change of a target object to generate detection data, that is, the detection component can be used to effectively detect the network port indicator light, thereby realizing simultaneous detection of the network port function and the network port indicator light, and effectively avoiding defective products from entering the whole machine assembly. It can not only reduce the defective rate during the whole machine testing, but also avoid the increase in assembly workload, thereby improving the factory efficiency of the whole machine.

[0043] On the other hand, the embodiment of the utility model further provides a detection system, Figure 3A schematic diagram of the structure of a detection system is shown. Figure 3 It can be seen that the detection system includes the above-mentioned detection device and detection equipment, and the detection device and the detection equipment are connected through the connecting part included in the detection device and the corresponding connecting line.
