Description

Technical Field

[0001] The present invention relates to the technical field of power supply fault detection, and in particular to a method for quickly locating and detecting a power supply fault and a detection device based on the method. Background Art

[0002] The power supply fault rapid positioning detection device is a special equipment used to quickly diagnose abnormal parts and fault types of the power supply system. It integrates signal acquisition, intelligent analysis and precise positioning functions. The device collects the electrical parameters and operating status data of each node of the power supply system (such as input lines, rectifier modules, filter circuits, output ports) in real time through voltage, current sensors and temperature sensors, and analyzes and processes the collected data in combination with embedded chips or intelligent algorithms. It uses fault feature libraries and pattern recognition technologies (such as neural networks and expert systems) to quickly identify fault types such as overvoltage, undervoltage, short circuit, overload, and component aging, and locates the specific location of the fault through topological analysis algorithms. Some devices support visual interfaces, which intuitively present fault points and fault paths in a graphical manner. The device is widely used in scenarios such as data centers, industrial production lines, and power systems, greatly shortening the time for power supply fault troubleshooting, reducing manual detection costs, and improving the reliability and operation and maintenance efficiency of the power supply system. It is a key technical equipment to ensure a stable power supply.

[0003] In the field of portable power supply fault detection, the human-computer interaction design of some current devices has significant operational bottlenecks, especially in one-handed operation scenarios, where the convenience of cable connection and tool use is particularly prominent. In pursuit of portability, these detection devices often adopt a compact design that can be held in one hand. However, their functions rely on external data cables (such as USB, alligator clip cables) or detection pen, resulting in a contradiction between the operation process and the holding method. When the user holds the detection device with one hand, the palm of the hand needs to simultaneously hold the device, view the screen, and operate the buttons. Since some detection scenarios require simultaneous device parameter setting and cable connection, one-handed operation requires frequent switching of holding posture and button operation, which can easily lead to operational errors and incorrect detection results. To this end, we propose a method for rapid power supply fault location detection and a detection device based on this method. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the present invention provides a method for quickly locating and detecting power supply faults and a detection device based on this method, which solves the problem that when using the existing power supply fault detection device, some detection scenarios require simultaneous device parameter settings and cable connections, and when operating with one hand, frequent switching of holding posture and button operations are required, which can easily lead to operational errors and cause erroneous detection results.

[0011] Preferably, a groove is provided on the rear side of the handle, the power supply mainboard is bolted to the inner wall of the groove, the power supply mainboard is electrically connected to the air pump, a cover plate is bolted to the inner wall of the groove, an assembly cavity is provided on the surface of the upper plug block 2, the spring pin is fixedly connected to the inner wall of the assembly cavity, a circular hole is provided on the side surface of the fuselage, a power supply pin adapted to the spring pin is fixedly connected to the inner wall of the circular hole of the fuselage, and a photoelectric sensor is fixedly connected to the inner wall of the adsorption cavity of the handle, and the control chip integrated on the power supply mainboard is used to enable the power supply mainboard to cooperate with the photoelectric sensor to automatically control the operation of the air pump when powered on, thereby facilitating the user to fix the fuselage in a suitable placement area.

[0012] Preferably, a filling cavity is provided inside the sealing ring, and the inside of the sealing ring filling cavity is filled with hydrogel to ensure that the contact portion between the sealing ring and objects such as walls can change according to the shape of the contact position to increase the fitting effect. The airway openings of airway one and airway two are fixedly connected to filter nets, and the filter nets can be used to filter the air coming out of the airway openings of airway one and airway two to prevent impurities such as dust from entering airway one or airway two through the airway openings, causing blockage of airway one or airway two.

[0013] Preferably, the sleeve is sleeved with the joint of the air pump, the input end of the air pump is communicated with the inside of the air duct one, the output end of the air pump is communicated with the inside of the air duct two, and the air pump in the working state can cooperate with the air duct one to pump the air in the adsorption cavity outward, so that the adsorption cavity forms a vacuum, thereby fixing the handle in a suitable placement area such as a wall.

[0014] Preferably, the holding frame abuts against the fixed inner wall before installation, the extrusion frame is inserted into the inside of the installation cavity, and the surface of the extrusion frame abuts against the holding frame, so that the user can conveniently install the air pump by using the holding frame, and after the air pump is placed in the installation cavity, the user can operate the holding frame to move the air pump, so that the joint of the air pump is inserted into the air duct.

[0015] Preferably, the power supply main board is electrically connected with the spring pin, the power supply pin is electrically connected with the machine body, and the photoelectric sensor is electrically connected with the power supply main board, so that the machine body supplies power to the power supply main board only after the user changes the state of the handle, thereby avoiding the problem that the air pump is powered on to work in a non-demand state, causing the power stored in the machine body to be wasted.

[0016] Preferably, the connecting device further comprises a catch, the inner wall of the fixed frame is provided with a receiving cavity, the fixed frame is slidably connected with the catch on the inner wall of the receiving cavity, the surfaces of the plug block one and the plug block two are provided with a catch groove matched with the catch, the surface of the catch is fixedly connected with a load ring, and the surface of the load ring is fixedly connected with a return spring, one end of the return spring away from the load ring is fixedly connected with the inner wall of the receiving cavity.

[0017] The inner wall of the receiving cavity is slidably connected with an L-shaped frame, the L-shaped frame is fixedly connected with the surface of the catch, the inner side of the L-shaped frame is fixedly connected with a protruding block, the fixed frame is slidably connected with a linkage frame on the inner wall of the receiving cavity, the protruding block is slidably connected with the inner wall of the linkage frame, the front surface of the linkage frame is fixedly connected with a jacking rod, and the front end of the jacking rod is fixedly connected with a pressing block, so that the catch can lock the positions of the plug block one or the plug block two inserted into the fixed frame in the locked state, to ensure that the handle is firmly connected with the machine body.

[0018] Preferably, one end of the catch away from the L-shaped frame is provided with a chamfer, the load ring is slidably connected with the inner wall of the receiving cavity, and the return spring is sleeved on the surface of the catch, so that the load ring can limit the position of the catch by the pushing force of the return spring, to ensure the stability of the catch in the locked state.

[0019] Preferably, the L-shaped frame abuts against the surface of the linkage frame, the opening of the linkage frame is arranged obliquely, the top rod is in sliding connection with the inner wall of the receiving cavity, and the pressing block is in sliding connection with the inner wall of the receiving cavity. By using the linkage frame, the two L-shaped frames on the two sides can be pulled by the convex block under the operation of the user to ensure that the two L-shaped frames can move synchronously, thereby ensuring that the two catches are unlocked synchronously.

[0020] Preferably, when the power failure is detected by the detection device S1, the detection device is ensured to be in a powered state. When the detection device is powered off, the charger connector is inserted into the data interface, and the charger is inserted into the socket with power supply. Then, the detection device can be charged under the action of the charger. After the charging is completed, the charger is removed, and the machine body is carried for movement;

[0021] S2, when the user moves to the power supply, the machine body is taken out. When there is a smooth wall, a shell or other place for placement in the use environment, the pressing block is pushed, the pressing block pushes the linkage frame together with the top rod, the linkage frame moves in the specified direction, and the L-shaped frame is pulled by the convex block. The catch is pulled out of the clamping groove, and the load ring is pressed to compress the reset spring. When the pressing block is completely inserted into the receiving cavity, the catch is completely separated from the clamping groove. Then, the handle can be pulled away from the machine body, and the insertion block one is separated from the fixed frame;

[0022] After the handle is removed, the catch is kept in the unlocked state. Then, the position of the handle is adjusted so that the insertion block two is aligned with the fixed frame. The handle is pushed to insert the insertion block two into the fixed frame. The pressing block is loosened, the top rod loses the force applied to the linkage frame, the linkage frame loses the pushing force applied to the convex block, the convex block loses the pulling force applied to the L-shaped frame, and the L-shaped frame stops pulling the catch. At the same time, the load ring stops pressing the reset spring, the reset spring loses the pressure and rebounds, and the catch is reset and inserted into the clamping groove of the insertion block two to lock the position of the insertion block two.

[0023] S3. After completing the above operations, the spring pin contacts the power supply pin and supplies power to the power supply mainboard, which supplies power to the photoelectric sensor. The sealing ring is then pressed against the wall or the device casing near the power supply. After the sealing ring is pressed tightly, the photoelectric sensor is blocked. The photoelectric sensor then controls the power supply mainboard to supply power to the air pump. The air pump is powered on and pumps out the gas in the adsorption chamber through air channel 1. The pumped gas is sent out through the output end of the air pump and air channel 2. A vacuum state is formed in the adsorption chamber, and the sealing ring is used to adsorb the handle on the wall or the device casing to limit the position of the fuselage. The user can then release both hands. When the user completes the inspection and needs to remove the fuselage, the power supply of the fuselage is turned off, the fuselage stops supplying power to the power supply mainboard, the power supply mainboard stops supplying power to the air pump, the air pump is powered off and stops pumping the gas in the adsorption chamber. The gas in the adsorption chamber gradually returns to the external air pressure range and loses the adsorption effect. When the adsorption chamber loses the adsorption effect, the fuselage can be removed from the fixed position.

[0024] S4. After the user secures the device, the user removes the data cable or electric pen connecting the body and the power supply, plugs the connecting end of the data cable or electric pen into the detection interface of the body, and plugs the other end into the power output interface. Then, the body is turned on and the body is operated through the control panel. The body operates under the power supply of the internal battery. During operation, the power supply is detected through the data cable or electric pen, and the power supply is scanned according to the voltage waveform analysis method, the impedance spectrum detection method or the energy flow tracking method to quickly locate the fault position of the power supply. The fault type and location are displayed on the display screen for the user to view. When the body is out of power, the body will alarm through the built-in integrated sound module to remind the user that the device is out of power.

[0025] In summary, the technical effects and advantages of the present invention are as follows:

[0026] 1. In the present invention, by providing an assisting device, when the user needs to use both hands to perform the detection operation, the device can be fixed on a wall or device casing near the detection power source to free both hands for the detection operation, thereby avoiding the need to hold the device with one hand during use, resulting in the user being able to use only one hand for operation, increasing the probability of operational errors and causing inaccurate detection results.

[0027] 2. In the present invention, by providing a connecting device, the auxiliary device for fixing the fuselage can change the installation state according to the use requirements, ensuring that the auxiliary device is in an unpowered state when there is no need for fixing. At the same time, the auxiliary device can be disassembled to reduce the space occupied by the detection device and improve the portability of the detection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The assisting device 7 further includes a power supply module consisting of a power supply mainboard 716 , a cover plate 717 , spring pins 718 , power supply pins 719 and a photoelectric sensor 720 .

[0053] Among them, a filling chamber 714 is opened inside the sealing ring 75, and the inside of the filling chamber 714 of the sealing ring 75 is filled with hydrogel to ensure that the contact part between the sealing ring 75 and the wall and other objects can change according to the shape of the contact position to increase the fitting effect. The airway openings of airway 1 76 and airway 2 77 are fixedly connected with a filter screen 715. The filter screen 715 can be used to filter the air out of the airway openings of airway 1 76 and airway 2 77 to prevent dust and other impurities from entering airway 1 76 or airway 2 77 through the airway opening, causing blockage of airway 1 76 or airway 2 77.

[0054] Among them, the sleeve 78 is connected to the joint of the air pump 710, the input end of the air pump 710 is connected to the interior of air channel 1 76, and the output end of the air pump 710 is connected to the interior of air channel 2 77. When the air pump 710 is in a working state, it can cooperate with air channel 1 76 to pump the air in the adsorption chamber 74 outward to form a vacuum in the adsorption chamber 74, thereby fixing the handle 72 in a suitable placement area such as a wall.

[0057] The connecting device 6 further includes a bayonet 63, a receiving cavity 62 is provided on the inner wall of the fixing frame 61, and the fixing frame 61 is slidably connected to the inner wall of the receiving cavity 62 with the bayonet 63. The surfaces of the first and second plug blocks 71 and 73 are both provided with a slot adapted to the bayonet 63. The surface of the bayonet 63 is fixedly connected to a load ring 64, and the surface of the load ring 64 is fixedly connected to a return spring 65. The end of the return spring 65 away from the load ring 64 is fixedly connected to the inner wall of the receiving cavity 62.

[0058] An L-shaped frame 66 is slidably connected to the inner wall of the storage cavity 62, and the L-shaped frame 66 is fixedly connected to the surface of the bayonet 63. A protrusion 67 is fixedly connected to the inner side of the L-shaped frame 66.

The return spring 65 applies a thrust to the load ring 64, so that the load ring 64 can limit the position of the bayonet 63 to ensure the stability of the bayonet 63 in the locked state.

[0060] Among them, the L-shaped frame 66 abuts against the surface of the linkage frame 68, the opening of the linkage frame 68 is set at an angle, the top rod 69 is slidably connected to the inner wall of the storage cavity 62, and the pressing block 610 is slidably connected to the inner wall of the storage cavity 62. The linkage frame 68 can be used to cooperate with the protrusion 67 to pull the L-shaped frames 66 on both sides under the operation of the user to ensure that the L-shaped frames 66 on both sides can move synchronously, thereby ensuring that the latches 63 on both sides are unlocked synchronously.

[0061] The working principle of the present invention is as follows: when using the detection device to detect power failure, ensure that the detection device is in a powered state. When the detection device is out of power, insert the charger connector into the data interface 5 and plug the charger into a socket with a power supply. Then, under the action of the charger, the detection device can be charged. After charging is completed, unplug the charger and carry the body 1 with you.

[0062] When the user moves to the power source, the body 1 is taken out. When the use environment has a smooth wall, shell, or other suitable place for placement, the user pushes the pressing block 610. The pressing block 610 cooperates with the push rod 69 to push the linkage frame 68. The linkage frame 68 moves in the specified direction and cooperates with the protrusion 67 to pull the L-shaped frame 66. The L-shaped frame 66 pulls the latch 63. The latch 63 slides out of the slot under the force and cooperates with the load-bearing ring 64 to squeeze the return spring 65. The return spring 65 is squeezed and deformed. When the pressing block 610 completely slides into the storage cavity 62, the latch 63 completely disengages from the slot. Then, the user can pull the handle 72 away from the body 1. The handle 72 pulls the insert block 1 71, and the insert block 1 71 disengages from the fixing frame 61.

[0063] After the handle 72 is removed, ensure that the latch 63 remains in the unlocked state, then adjust the position of the handle 72 so that the second plug block 73 is aligned with the fixing frame 61, push the handle 72, and the handle 72 pushes the second plug block 73 to insert into the fixing frame 61, release the button 610, the top rod 69 loses the force applied to the linkage frame 68, the linkage frame 68 loses the thrust applied to the protrusion 67, the protrusion 67 loses the pulling force on the L-shaped frame 66, the L-shaped frame 66 stops pulling the latch 63, and the load ring 64 stops squeezing the reset spring. The spring 65 loses pressure and rebounds, and cooperates with the load ring 64 to push the bayonet 63 to reset. The bayonet 63 is reset and inserted into the slot of the second plug block 73, and the position of the second plug block 73 is locked. By providing the connecting device 6, the auxiliary device 7 for fixing the fuselage 1 can be changed in the installation state according to the use requirements, ensuring that the auxiliary device 7 is in a non-powered state when it is not required to be fixed. At the same time, the auxiliary device 7 can be disassembled to reduce the space occupied by the detection device and improve the portability of the detection device.

[0064] After completing the above operations, the spring pin 718 contacts the power supply pin 719 and supplies power to the power supply mainboard 716. The power supply mainboard 716 supplies power to the photoelectric sensor 720, and then the sealing ring 75 is pressed against the wall or the device casing near the power supply. After the sealing ring 75 is pressed tightly, the photoelectric sensor 720 is blocked, and then the photoelectric sensor 720 controls the power supply mainboard 716 to supply power to the air pump 710. The air pump 710 is powered on and pumps out the gas in the adsorption chamber 74 through the air channel 1 76. The pumped gas is sent out through the output end of the air pump 710 and the air channel 2 77. A vacuum state is formed in the adsorption chamber 74, and the sealing ring 75 is used to adsorb the handle 72 on the wall or the device casing to limit the position of the fuselage 1. Then the user can release his hands. When the user needs to remove the body 1 after completing the test, the power supply of the body 1 is turned off, the body 1 stops supplying power to the power supply mainboard 716, the power supply mainboard 716 stops supplying power to the air pump 710, the air pump 710 is powered off and stops pumping the gas in the adsorption chamber 74, and the gas in the adsorption chamber 74 gradually returns to the external air pressure range and loses the adsorption effect. When the adsorption chamber 74 loses the adsorption effect, the body 1 can be removed from the fixed position.
