Description

Technical Field

[0001] This invention relates to the field of power supply fault detection technology, specifically to a method for rapid location and detection of power supply faults and a detection device based on this method. Background Technology

[0002] The power supply fault rapid location and detection device is a specialized piece of equipment used for quickly diagnosing abnormal parts and fault types in power systems. It integrates signal acquisition, intelligent analysis, and precise location functions. This device collects electrical parameters and operating status data of various nodes in the power system (such as input lines, rectifier modules, filter circuits, and output ports) in real time using voltage, current, and temperature sensors. Combined with embedded chips or intelligent algorithms, the collected data is analyzed and processed. Utilizing fault feature libraries and pattern recognition technologies (such as neural networks and expert systems), it quickly identifies fault types such as overvoltage, undervoltage, short circuit, overload, and component aging, and locates the specific location of the fault using topology analysis algorithms. Some devices support a visual interface, intuitively presenting the fault point and fault path graphically. This device is widely used in data centers, industrial production lines, power systems, and other scenarios, significantly shortening power supply fault investigation time, reducing manual inspection costs, and improving the reliability and operation and maintenance efficiency of power systems. It is a key technical equipment for ensuring a stable power supply.

[0003] In the field of portable power supply fault detection, the human-computer interaction design of some current devices suffers from significant operational bottlenecks, especially in one-handed operation scenarios, where the convenience of cable connection and tool use is particularly prominent. These detection devices, in pursuit of portability, often adopt a compact design that can be held in one hand. However, their functionality relies on external data cables (such as USB or alligator clip cables) or testing pens, creating a conflict between the operation process and the grip method. When a user holds the detection device with one hand, their palm must simultaneously hold the device, view the screen, and operate the buttons. Since some detection scenarios require simultaneous device parameter settings and cable connections, frequent switching between grip posture and button operation during one-handed operation can easily lead to operational errors and incorrect detection results. Therefore, we propose a rapid power supply fault location and detection method and a detection device based on this method. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a method for rapid location and detection of power supply faults and a detection device based on this method. This solves the problem that existing power supply fault detection devices require simultaneous device parameter settings and cable connections in some detection scenarios, and frequent switching of grip posture and button operation during one-handed operation, which can easily lead to operational errors and incorrect detection results.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for rapid location and detection of power supply faults and a detection device based on the method, comprising a body, a control panel fixedly connected to the surface of the body, a display screen fixedly connected to the surface of the body, a detection interface provided on the upper surface of the body, a data interface provided on the upper surface of the body, connecting devices for assembly provided on both sides of the body, and an assisting device provided on the side of the connecting device away from the body;

[0008] The connecting device includes a fixing frame, which is fixedly connected to the side surface of the fuselage;

[0009] The assisting device includes a first insert block, which is inserted into the inner wall of a first fixed frame. A handle is fixedly connected to the side surface of the first insert block, and a second insert block is fixedly connected to the rear side of the handle. An adsorption chamber is formed on the side of the handle away from the machine body. A sealing ring is fixedly connected to the inner wall of the adsorption chamber. An air passage is formed on the inner wall of the adsorption chamber. An air passage is formed inside the handle. Sleeves are fixedly connected to the inner walls of both air passages. An installation cavity is formed on the front surface of the handle. An air pump is installed on the inner wall of the installation cavity. A gripping frame is fixedly connected to the surface of the air pump. A limiting frame is bolted to the inner wall of the installation cavity. A squeezing frame is fixedly connected to the inner side of the limiting frame.

[0010] The assist device also includes a power supply module consisting of a power supply motherboard, a cover plate, spring pins, power supply pin A, and a photoelectric sensor.

[0011] Preferably, a groove is provided on the rear side of the grip, the power supply main board is bolted to the inner wall of the groove, the power supply main board 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 insert block two, 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 body, a power supply pin B adapted to the spring pin is fixedly connected to the inner wall of the circular hole on the body, and a photoelectric sensor is fixedly connected to the inner wall of the suction cavity on the grip. By utilizing the control chip integrated on the power supply main board, the power supply main board can work with the photoelectric sensor to automatically control the air pump to work when powered on, thereby making it convenient for the user to fix the body in a suitable placement area.

[0012] Preferably, the sealing ring has an internal filling cavity filled with hydrogel to ensure that the contact area between the sealing ring and the wall or other objects can change shape according to the contact position to increase the fit. The air inlets of airway one and airway two are fixedly connected to filter screens. The filter screens can filter the air coming out of the air inlets of airway one and airway two to prevent dust and other impurities from entering airway one or airway two through the air inlets and causing blockage.

[0013] Preferably, the sleeve is connected to the connector of the air pump, the input end of the air pump is connected to the interior of air passage one, and the output end of the air pump is connected to the interior of air passage two. Using the air pump in the working state, it can work with air passage one to pump air out of the adsorption chamber to form a vacuum in the adsorption chamber, thereby fixing the handle to a suitable placement area such as a wall.

[0014] Preferably, the gripping frame abuts against the inner wall of the pre-installation fixed frame, the squeezing frame is inserted into the interior of the installation cavity, and the squeezing frame abuts against the surface of the gripping frame. The gripping frame allows the user to easily install the air pump, so that after the air pump is placed into the installation cavity, the user can operate the gripping frame to move the air pump, so that the air pump connector is inserted into the air passage.

[0015] Preferably, the power supply main board is electrically connected to the spring pin, the power supply pin A is electrically connected to the body, and the photoelectric sensor is electrically connected to the power supply main board. By utilizing the cooperation of the spring pin and the power supply pin A, the body will only supply power to the power supply main board after the user changes the grip state, thus avoiding the problem of the air pump being powered on and working when not needed, which would waste the power stored in the body.

[0016] Preferably, the connecting device further includes a locking pin, the inner wall of the fixing frame is provided with a storage cavity, the fixing frame is slidably connected to the inner wall of the storage cavity with a locking pin, the surfaces of the first insert and the second insert are provided with slots that are adapted to the locking pin, a force-bearing ring is fixedly connected to the surface of the locking pin, a return spring is fixedly connected to the surface of the force-bearing ring, and the end of the return spring away from the force-bearing ring is fixedly connected to the inner wall of the storage cavity;

[0017] An L-shaped frame is slidably connected to the inner wall of the storage cavity. The L-shaped frame is fixedly connected to the surface of the locking pin. A protrusion is fixedly connected to the inner side of the L-shaped frame. A linkage frame is slidably connected to the inner wall of the storage cavity. The protrusion is slidably connected to the inner wall of the linkage frame. A top rod is fixedly connected to the front surface of the linkage frame. A push block is fixedly connected to the front end of the top rod. Using the locking pin, the position of the first or second insertion block inserted in the fixing frame can be locked in the locked state to ensure a firm connection between the handle and the body.

[0018] Preferably, the end of the locking pin away from the L-shaped frame is chamfered, the force-bearing ring is slidably connected to the inner wall of the storage cavity, and the return spring is sleeved on the surface of the locking pin. The force-bearing ring is pushed by the return spring, so that the force-bearing ring can restrict the position of the locking pin to ensure the stability of the locking pin 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 inclined, the top rod is slidably connected to the inner wall of the storage cavity, and the push block is slidably connected to the inner wall of the storage cavity. The linkage frame can be used by the user to pull the L-shaped frames on both sides in conjunction with the protrusion to ensure that the L-shaped frames on both sides can move synchronously, thereby ensuring that the locking pins on both sides unlock synchronously.

[0020] Preferably, S1, when using the detection device to detect power failure, ensure that the detection device is powered. When the detection device is out of power, insert the charger connector into the data interface and plug the charger into a power socket. Then, the detection device can be charged by the charger. After charging is complete, unplug the charger and carry the device with you.

[0021] S2. When the user moves to the power source, remove the device. When there is a smooth wall or outer casing in the environment, push the button. The button, together with the top rod, pushes the linkage frame. The linkage frame moves in the specified direction and, together with the protrusion, pulls the L-shaped frame. The L-shaped frame pulls the locking pin. The locking pin slides out of the slot under force and, together with the load ring, squeezes the return spring. The return spring is squeezed and deformed. When the button slides completely into the storage cavity, the locking pin completely disengages from the slot. Then, the handle can be pulled away from the device. The handle pulls the first insertion block, and the first insertion block disengages from the fixing frame.

[0022] After the handle is removed, ensure the locking pin remains in the unlocked position. Then adjust the position of the handle so that the second insert block is aligned with the fixing bracket. Push the handle, and the handle pushes the second insert block into the fixing bracket. Release the button, and the push rod loses the force applied to the linkage bracket. The linkage bracket loses the pushing force applied to the protrusion. The protrusion loses the pulling force on the L-shaped bracket. The L-shaped bracket stops pulling the locking pin. At the same time, the load ring stops compressing the return spring. The return spring loses pressure and rebounds, and together with the load ring, pushes the locking pin to reset. The locking pin resets and inserts into the slot of the second insert block, locking the position of the second insert block.

[0023] S3. After completing the above operations, the spring pin contacts the power supply pin A and supplies power to the power supply main board. The power supply main board supplies power to the photoelectric sensor. Then, the sealing ring is pressed against the wall or the device casing near the power source. After the sealing ring is pressed tightly, the photoelectric sensor is blocked. Then, the photoelectric sensor controls the power supply main board to supply power to the air pump. The air pump is powered on and pumps the gas in the adsorption chamber out through air channel one. The pumped gas is sent out through the output end of the air pump and air channel two, forming a vacuum state in the adsorption chamber. With the help of the sealing ring, the handle is adsorbed onto the wall or the device casing to restrict the position of the machine body. Then, the user can free their hands. When the user finishes the test and needs to remove the machine body, turn off the power of the machine body. The machine body stops supplying power to the power supply main board, the power supply main board stops supplying power to the air pump, and the air pump stops pumping the gas in the adsorption chamber. Then, 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 machine body can be removed from the fixed position.

[0024] S4. After the user secures the device, remove the data cable or test pen connecting the device and the power supply. Plug one end of the data cable or test pen into the detection interface on the device and the other end into the power output interface. Then turn on the device and operate it via the control panel. The device operates on the power of its internal battery and detects the power supply via the data cable or test pen. It scans the power supply using methods such as voltage waveform analysis, impedance spectroscopy, or energy flow tracing to quickly locate the fault. The fault type and location are displayed on the screen for the user to view. When the device is out of power, it will sound an alarm through its built-in integrated sound module to alert the user.

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

[0026] 1. In this invention, by setting up an assistive device, when the user needs to perform the detection operation with both hands, the device can be fixed on the wall or equipment casing near the detection power source, so as to free up both hands to perform the detection operation. This avoids the problem that the user has to use only one hand to operate the device during use, which increases the probability of operation errors and causes inaccurate detection results.

[0027] 2. In this invention, by setting a connecting device, the auxiliary device used to fix the machine body can change its installation state according to the usage requirements, ensuring that the auxiliary device is in a non-powered state when there are no fixed requirements. 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. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] refer to Figures 1-16 The power supply fault rapid location detection method and detection device based on the method shown include a body 1, a control panel 2 fixedly connected to the surface of the body 1, a display screen 3 fixedly connected to the surface of the body 1, a detection interface 4 provided on the upper surface of the body 1, a data interface 5 provided on the upper surface of the body 1, and connection devices 6 for assembly provided on both sides of the body 1. An assisting device 7 is provided on the side of the connection device 6 away from the body 1.

[0050] The connecting device 6 includes a fixing frame 61, which is fixedly connected to the side surface of the body 1;

[0051] The assisting device 7 includes a first insert 71, which is inserted into the inner wall of the fixed frame 61. A handle 72 is fixedly connected to the side surface of the first insert 71, and a second insert 73 is fixedly connected to the rear side of the handle 72. An adsorption chamber 74 is opened on the side of the handle 72 away from the body 1. A sealing ring 75 is fixedly connected to the inner wall of the handle 72 in the adsorption chamber 74. An air passage 76 is opened on the inner wall of the handle 72 in the adsorption chamber 74. An air passage 77 is opened inside the handle 72. A sleeve 78 is fixedly connected to the inner wall of both the first air passage 76 and the second air passage 77. An installation cavity 79 is opened on the front surface of the handle 72. An air pump 710 is installed on the inner wall of the installation cavity 79. A gripping frame 711 is fixedly connected to the surface of the air pump 710. A limit frame 712 is bolted to the inner wall of the installation cavity 79. A compression frame 713 is fixedly connected to the inner side of the limit frame 712.

[0052] The assist device 7 also includes a power supply module consisting of a power supply main board 716, a cover plate 717, a spring pin 718, a power supply pin A719, and a photoelectric sensor 720.

[0053] The handle 72 has a groove on its rear side, and the power supply main board 716 is bolted to the inner wall of the groove. The power supply main board 716 is electrically connected to the air pump 710. A cover plate 717 is bolted to the inner wall of the groove. An assembly cavity is formed on the surface of the upper insert block 73. A spring pin 718 is fixedly connected to the inner wall of the assembly cavity. A round hole is formed on the side surface of the body 1. A power supply pin B that matches the spring pin 718 is fixedly connected to the inner wall of the round hole. A photoelectric sensor 720 is fixedly connected to the inner wall of the suction cavity 74 on the handle 72. By utilizing the control chip integrated on the power supply main board 716, the power supply main board 716 can work with the photoelectric sensor 720 to automatically control the air pump 710 to work when powered on, thus making it convenient for the user to fix the body 1 in a suitable placement area.

[0054] The sealing ring 75 has an internal filling cavity 714 filled with hydrogel to ensure that the contact area between the sealing ring 75 and the wall or other objects can change shape according to the contact position to increase the fit. The air passage openings of air passage one 76 and air passage two 77 are fixedly connected to filter screens 715. The filter screens 715 can filter the air coming out of the air passage openings of air passage one 76 and air passage two 77 to prevent dust and other impurities from entering air passage one 76 or air passage two 77 through the air passage openings, which would cause blockage of air passage one 76 or air passage two 77.

[0055] The sleeve 78 is connected to the connector of the air pump 710. The input end of the air pump 710 is connected to the inside of the first air passage 76, and the output end of the air pump 710 is connected to the inside of the second air passage 77. The air pump 710 in the working state can work with the first air passage 76 to pump air out of the adsorption chamber 74, so that the adsorption chamber 74 forms a vacuum, thereby fixing the handle 72 to a suitable placement area such as a wall.

[0056] The grip 711 abuts against the inner wall of the pre-installation fixed part, and the compression frame 713 is inserted into the installation cavity 79. The compression frame 713 abuts against the surface of the grip 711. The grip 711 allows the user to easily install the air pump 710. After the air pump 710 is placed into the installation cavity 79, the user can operate the grip 711 to move the air pump 710, so that the connector of the air pump 710 is inserted into the air passage.

[0057] The power supply main board 716 is electrically connected to the spring pin 718, the power supply pin A719 is electrically connected to the body 1, and the photoelectric sensor 720 is electrically connected to the power supply main board 716. By utilizing the cooperation of the spring pin 718 and the power supply pin A719, the body 1 will only supply power to the power supply main board 716 after the user changes the state of the grip 72. This avoids the problem of the air pump 710 being powered on and working when not needed, which would waste the power stored in the body 1.

[0058] The connecting device 6 also includes a locking pin 63. The inner wall of the fixing frame 61 is provided with a storage cavity 62. The locking pin 63 is slidably connected to the inner wall of the storage cavity 62. The surfaces of the first insertion block 71 and the second insertion block 73 are provided with slots that are adapted to the locking pin 63. A force-bearing ring 64 is fixedly connected to the surface of the locking pin 63. A return spring 65 is fixedly connected to the surface of the force-bearing ring 64. The end of the return spring 65 away from the force-bearing ring 64 is fixedly connected to the inner wall of the storage cavity 62.

[0059] An L-shaped frame 66 is slidably connected to the inner wall of the storage cavity 62. The L-shaped frame 66 is fixedly connected to the surface of the locking pin 63. A protrusion 67 is fixedly connected to the inner side of the L-shaped frame 66. A linkage frame 68 is slidably connected to the inner wall of the storage cavity 62, and the protrusion 67 is slidably connected to the inner wall of the linkage frame 68. A push rod 69 is fixedly connected to the front surface of the linkage frame 68. A push block 610 is fixedly connected to the front end of the push rod 69. Using the locking pin 63, the position of the first insertion block 71 or the second insertion block 73 inserted in the fixing frame 61 can be locked in the locked state to ensure that the handle 72 is firmly connected to the body 1.

[0060] The end of the locking pin 63 away from the L-shaped frame 66 is chamfered. The force-carrying ring 64 is slidably connected to the inner wall of the storage cavity 62. The return spring 65 is sleeved on the surface of the locking pin 63. The force applied by the return spring 65 to the force-carrying ring 64 can restrict the position of the locking pin 63 to ensure the stability of the locking pin 63 in the locked state.

[0061] The L-shaped frame 66 abuts against the surface of the linkage frame 68, the opening of the linkage frame 68 is inclined, the top rod 69 is slidably connected to the inner wall of the storage cavity 62, and the button 610 is slidably connected to the inner wall of the storage cavity 62. With the help of the linkage frame 68, the user can pull the L-shaped frames 66 on both sides in conjunction with the protrusion 67 to ensure that the L-shaped frames 66 on both sides can move synchronously, thereby ensuring that the locking pins 63 on both sides unlock synchronously.

[0062] The working principle of this 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 power. Then, under the action of the charger, the detection device can be charged. After charging is completed, unplug the charger and carry the device body 1 with you.

[0063] When the user moves to the power source, remove the main body 1. When there is a smooth wall or shell in the environment where it can be placed, push the button 610. The button 610, together with the push rod 69, pushes the linkage frame 68. The linkage frame 68 moves in the specified direction and, together with the protrusion 67, pulls the L-shaped frame 66. The L-shaped frame 66 pulls the locking pin 63. The locking pin 63 is forced to slide out of the slot and, together with the load ring 64, squeezes the return spring 65. The return spring 65 is squeezed and deformed. When the button 610 slides completely into the storage cavity 62, the locking pin 63 completely disengages from the slot. Then, the handle 72 can be pulled away from the main body 1. The handle 72 pulls the insertion block 71, and the insertion block 71 disengages from the fixing frame 61.

[0064] After the grip 72 is removed, ensure that the locking pin 63 remains in the unlocked position. Then, adjust the position of the grip 72 so that the insert block 73 is aligned with the fixing bracket 61. Push the grip 72, and the grip 72 pushes the insert block 73 into the fixing bracket 61. Release the button 610, and the push rod 69 loses the force applied to the linkage bracket 68. The linkage bracket 68 loses the pushing force applied to the protrusion 67, and the protrusion 67 loses the pulling force on the L-shaped bracket 66. The L-shaped bracket 66 stops pulling the locking pin 63, and at the same time, the load ring 64 stops compressing the reset spring. Spring 65, the return spring 65 loses pressure and rebounds, and together with the load ring 64 pushes the locking pin 63 to reset. The locking pin 63 resets and inserts into the slot of the second plug 73, and locks the position of the second plug 73. By setting the connecting device 6, the installation state of the auxiliary device 7 used to fix the body 1 can be changed according to the usage requirements. It ensures that the auxiliary device 7 is in a non-powered state when not 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.

[0065] After the above operations are completed, spring pin 718 contacts power supply pin A719 and supplies power to power supply motherboard 716. Power supply motherboard 716 supplies power to photoelectric sensor 720, and then seals ring 75 against the wall or device housing near the power source. After sealing ring 75 is tightened, photoelectric sensor 720 is blocked. Photoelectric sensor 720 then controls power supply motherboard 716 to supply power to air pump 710. Air pump 710 is powered on and pumps gas out of adsorption chamber 74 through air passage 1 76. The pumped gas is sent out through the output end of air pump 710 and air passage 2 77, creating a vacuum state in adsorption chamber 74. With the help of sealing ring 75, handle 72 is adsorbed onto the wall or device housing to restrict the position of the device body 1, allowing the user to free their hands. When the user needs to remove the main body 1 after completing the test, the power supply of the main body 1 is turned off. The main body 1 stops supplying power to the main power supply board 716, and the main power supply board 716 stops supplying power to the air pump 710. The air pump 710 stops pumping gas in the adsorption chamber 74 after being de-energized. Then the gas in the adsorption chamber 74 gradually returns to the external air pressure range and loses its adsorption effect. When the adsorption chamber 74 loses its adsorption effect, the main body 1 can be removed from the fixed position. By setting up the assistance device 7, when the user needs to perform the test operation with both hands, the device can be fixed to the wall or equipment shell near the test power supply to free up both hands for the test operation. This avoids the problem of having to use one hand to hold the device during use, which would increase the probability of operation errors and cause inaccurate test results.

[0066] After the user secures the device, remove the data cable or test pen connecting the main unit 1 and the power supply. Plug the data cable or test pen into the detection interface 4 of the main unit 1 and the other end into the power output interface. Then turn on the main unit 1 and operate it via the control panel 2. The main unit 1 operates under the power of its internal battery.
