[0029] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] like Figure 1 and Figure 2As shown, a power supply monitoring device for a front-end detection unit in one embodiment of the present invention includes a detection mechanism 1 and a power supply monitoring mechanism 2; the detection mechanism 1 includes a mounting platform 11, a lifting component 12, a swing seat 13 and a probe 14 for detecting the voltage of the power supply device, the lifting component 12 is rotatably connected to the mounting platform 11, the swing seat 13 is rotatably connected to the lifting component 12, and the probe 14 is connected to the swing seat 13 and can be lifted and lowered relative to the mounting platform 11; the power supply monitoring mechanism 2 includes a shell 21 and a power supply monitoring module 22 installed in the shell 21, the power supply monitoring module 22 is electrically connected to the probe 14, a drainage groove and a lead hole are provided on the shell 21, and a dust plug is installed on the lead hole.

[0031] The power supply monitoring device for the front-end detection unit is provided with a lifting component 12, which can drive the lifting movement of the probe 14, thereby adjusting the detection height of the probe 14, so as to facilitate the probe 14 to perform power supply detection on the power supply device; by providing a swing seat 13, the swing of the swing seat 13 can drive the probe 14 to adjust the detection angle; by providing a drainage groove, it is convenient to collect and treat the accumulated water on the shell 21; by providing a dust plug, it can prevent dust from entering the shell 21 through the lead hole, avoiding the accumulation of dust in the shell 21 and affecting the operation of the components in the shell 21; by providing a detection mechanism 1 and a power supply detection mechanism, the problems of more dust and water accumulation inside the power supply monitoring equipment and the low degree of automation are solved.

[0032] like Figure 2 As shown, in one embodiment, the housing 21 is also provided with a drainage groove, a drainage hole 211 and a waterproof plate 212 located at the bottom of the housing 21. The drainage hole 211 is connected between the drainage groove and the drainage groove. The waterproof plate 212 is provided with a water storage groove and a drainage hole 213 connected to the water storage groove. The drainage groove is connected to the water storage groove at one end away from the drainage hole 211. In this way, when the drainage groove collects accumulated water, the accumulated water flows from the drainage groove to the drainage hole 211. After passing through the drainage hole 211, the accumulated water flows from the drainage groove from top to bottom to the water storage groove for temporary storage. When the accumulated water fills the water storage groove, the accumulated water can flow out from the drainage hole 213 to complete the drainage operation.

[0033] Specifically, the drainage groove is located at the top of the shell 21, the waterproof plate 212 is located at the bottom of the shell 21, and the drainage groove is arranged from top to bottom.

[0035] like Figure 3 As shown, in one embodiment, the lifting assembly 12 includes a first driving member 121, a second driving member 122, a connecting frame 123, and a fixed plate 124 connected to the rotating member 112; one end of the connecting frame 123 is slidably connected to the fixed plate 124, and the other end of the connecting frame 123 is connected to the second driving member 122, the second driving member 122 is connected to the swing seat 13 and is used to drive the swing seat 13 to swing, and the second driving member 122 is installed on the connecting frame 123 and is used to drive the sliding of the connecting frame 123. In this way, by providing the first driving member 121, the first driving member 121 drives the sliding of the connecting frame 123, thereby driving the lifting and lowering movement of the probe 14; by providing the second driving member 122, the second driving member 122 drives the swing seat 13 to swing, thereby adjusting the detection angle of the probe 14.

[0036] In one embodiment, the dust plug includes a plug head, a gasket, and a mounting seat installed on the lead-in port; the plug head, the gasket, and the mounting seat are stacked in sequence, and one end of the plug head passes through the gasket and the mounting seat in sequence and is plugged into the lead-in port. In this way, by providing a gasket, the gap between the plug head and the mounting seat is sealed, and dust is prevented from entering the housing 21 to a certain extent; by providing a plug head, when power supply monitoring is not required, the lead-in port is sealed, which is beneficial to dust prevention.

[0037] like Figure 1-3 As shown, in one embodiment, the power supply monitoring device further includes a transfer mechanism 3 for moving the detection mechanism 1 and the power supply monitoring mechanism 2 , and the base 111 and the housing 21 are both mounted on the transfer mechanism 3 .

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, specifically, the transfer mechanism 3 includes a transfer assembly 31 and a support plate 32 for supporting the base 111 and the housing 21; the transfer assembly 31 includes a first rotating member 311, a second rotating member 312, a connecting member 313, and a sliding wheel 314 mounted on the connecting member 313, the first rotating member 311 is rotatably connected to the support plate 32, and the second rotating member 312 is rotatably connected between the first rotating member 311 and the connecting member 313. In this way, the height of the supporting plate 32 can be adjusted by rotating the first rotating member 311 and the second rotating member 312, thereby adjusting the detection height of the probe 14; by providing the connecting member 313, the rotation of the connecting member 313 can change the sliding direction of the sliding wheel 314, thereby facilitating the control of the transfer direction of the transfer mechanism 3.

[0039] Furthermore, the outer contour of the supporting plate 32 is a hexagon, the number of the transfer components 31 is multiple, and the multiple first rotational connections are respectively rotationally connected to the six corners of the supporting plate 32.

[0040] like Figure 4 As shown, in one embodiment, the power supply monitoring module 22 includes a processor 221 and a power supply monitoring circuit 222 connected to a general input / output GPIO interface of the processor 221. The power supply monitoring circuit 222 is used to monitor the power supply device. If a first level is detected at the GPIO interface, the processor 221 is used to determine that the power supply device is Ethernet power supply POE; if a second level is detected at the GPIO interface, the processor 221 is used to determine that the power supply device is a direct current DC power supply, and the first level is different from the second level. The wireless access point AP is the most commonly used device when forming a small wireless local area network. It can be understood as a bridge connecting a wired network and a wireless network, which is used to connect various wireless network clients together and then connect the wireless network to the Ethernet. Therefore, a traditional AP is usually compatible with two power supply modes: Ethernet power supply POE and direct current DC power supply; in this way, through a power supply detection circuit connected to a GPIO of the processor 221, it is determined whether the power supply device that powers the processor 221 is POE or DC power supply. Compared with the prior art, a power supply detection device connected to the GPIO is reduced, which is conducive to reducing the interference of the GPIO on the radio frequency performance of the AP.

[0041] In one embodiment, the power supply monitoring circuit 222 is connected to a DC power supply, the first level is a high level, and the second level is a low level; or the power supply monitoring circuit 222 is connected to a POE, the first level is a low level, and the second level is a high level.

[0042] In one embodiment, a connection wire is disposed on the processor 221 , and the connection wire passes through the lead hole to be electrically connected to the probe 14 .

[0043] In one embodiment, an insulating sheath is provided on the outside of the connecting wire, and the insulating sheath is wound around the connecting wire, so that the safety performance is good, the connecting wire is better protected, and the aging speed of the connecting wire is reduced.

[0044] like Figure 1 , Figure 2 and Figure 6As shown, in one embodiment, the power supply monitoring device also includes a temperature measuring mechanism 4, which includes a fixed seat 41, a third rotating member 42, a fourth rotating member 43, a mounting member 44, a first connector 45, a second connector 46, and a temperature measuring head 47 mounted on the mounting member 44; the fixed seat 41 is mounted on the housing 21, one end of the first connector 45 is connected to the fixed seat 41, the other end of the first connector 45 is rotatably connected to the third rotating member 42, the fourth rotating member 43 is rotatably connected between the third rotating member 42 and the second connector 46, and the second connector 46 is connected to the mounting member 44. In this way, the detection height and angle of the temperature measuring head 47 can be adjusted by rotating the third rotating member 42 and the fourth rotating member 43, which is conducive to improving the accuracy of temperature detection.

[0045] Furthermore, the temperature measuring mechanism 4 also includes a temperature dial 48 mounted on the fifth rotating member, and the temperature dial 48 is electrically connected to the temperature measuring head 47 .

[0046] Specifically, the outer contours of the first connecting head 45 and the second connecting head 46 are both spherical.

[0047] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, the power supply monitoring device also includes an alarm mechanism 5, the alarm mechanism 5 includes a mounting shell 51, a support block 52 and an alarm component 53 installed in the mounting shell 51; the support block 52 is connected between the housing 21 and the mounting shell 51, and the alarm component 53 includes a buzzer 531, a power module 532 and a control module 533, the power module 532 is electrically connected to the control module 533, and the control module 533 is electrically connected to the probe 14, the temperature measuring head 47 and the buzzer 531 respectively. In this way, by providing the control module 533, the control module 533 obtains the voltage information of the probe 14 and the temperature information of the temperature measuring head 47, and compares them with the preset values ​​in the control module 533 respectively. If the voltage information cannot be obtained, the control module 533 determines that the power supply device is powered off, so that the control module 533 controls the buzzer 531 to alarm; if the obtained temperature information exceeds the preset value, the control module 533 controls the buzzer 531 to alarm.

[0048] Specifically, there are plural supporting blocks 52 .

[0049] Working principle:

[0050] When the probe 14 detects the voltage of the power supply device, if the voltage information cannot be obtained, the control module 533 determines that the power supply device is powered off, so that the control module 533 controls the buzzer 531 to alarm; if the level detected at the GPIO interface is a high level, the processor 221 determines that the power supply device is Ethernet Power POE; if the level detected at the GPIO interface is a low level, the processor 221 determines that the power supply device is a direct current DC power supply;

[0051] When the temperature measuring head 47 detects the temperature of the power supply device, if the acquired temperature information exceeds a preset value, the control module 533 controls the buzzer 531 to sound an alarm.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
