Description

Technical Field

[0001] This application belongs to the technical field of subway vehicle maintenance tools, and in particular relates to a glove-type inspection device for subway maintenance. Background Technology

[0002] Currently, subway maintenance mainly relies on handheld electronic endoscopes, which have the following disadvantages: ① Inconvenient operation: It requires two hands to operate (one hand holds the mirror, and the other hand controls the angle of the endoscope through the wired screen). If there are obstacles on the path, multiple people are needed to help move the obstacles, which is inefficient. ②Limited camera turning angle: Inflexible, making it difficult to observe tricky locations such as inside the wall panels of subway cars, behind electrical cabinets, inside the driver's cab, and under-car electrical equipment obstructions; ③ Bulky equipment: The video screen is bulky, difficult to hold and fix, and cannot be synchronized with hand movements.

[0003] ④ Traditional industrial gloves lack visual assistance functions, requiring maintenance personnel to frequently switch tools. Utility Model Content

[0004] In view of this, this application aims to provide a glove-type inspection device for subway maintenance to solve at least one of the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: This application provides a glove-type inspection device for subway maintenance, including a glove end and a receiving and display end; The glove end includes a glove, and a camera is provided on the fingertip of the index finger of the glove.

[0018] Please see Figures 1 to 4 As shown, this embodiment provides a glove-type inspection device for subway maintenance, including a glove end and a receiving and display end; The glove includes a glove, and a camera is installed on the fingertip of the glove. The camera is connected to a transmitting module and a first step-down module located on the back of the glove via an FPC cable. The transmitting module and the first step-down module are connected to a power module, which is detachably mounted on the glove. The receiving display includes a portable screen, which is connected to the receiving module via a video decoding module. Data is transmitted between the receiving module and the transmitting module. The receiving module and the video decoding module are also connected to the second battery compartment via a second step-down module (in this embodiment, the step-down module is an MP1584EN step-down board with an input of 4-28V and an output of 0.8-20V adjustable). The second battery compartment is connected to the portable screen.

[0019] Specifically, in this embodiment, for the glove end portion, the OV2640 camera is fixed to the index finger pad of the aramid glove with AB glue, and the surface is protected with a silicone cushioning sleeve. The camera is connected to the LoRa transmitting module via an FPC cable. The first battery compartment is connected to the power management module (in this embodiment, the HX6003 chip is used), and then the power is split into two paths. One path supplies power to the camera through the step-down module (in this embodiment, the MP1584EN chip is used), and the other path directly supplies power to the LoRa transmitter module. All modules are protected with nylon protective covers to avoid bumps and knocks.

[0020] For the receiving and display end, connect the GPIO port of the video decoding module to the LoRa receiving module, and connect the HDMI output port of the video decoding module to the portable screen. The second battery compartment is divided into two connections: one power supply is provided to the receiving module and video decoding module via a step-down module (MP1584EN chip in this embodiment), and the other is directly connected to the portable screen.

[0021] After the gloves are put on, the index finger camera captures an image of the back of the slit / component → the image data is compressed and transmitted through the LoRa module → the receiving end decompresses the data → the Raspberry Pi decodes the data → the HDMI output is sent to the screen → the maintenance personnel move the obstruction with one hand to observe the image in real time and locate the fault.

[0022] The receiving end screen is glued to the four corner suction cup brackets → the suction cups adhere to the wall → the screen angle can be freely adjusted, solving the problem that operators need to hold the screen by hand and that it is difficult for a single person to operate the equipment.

[0023] The device described in this embodiment can simultaneously complete the "moving object + observation" action with one hand. After the screen is attached, it frees up both hands, and maintenance personnel can operate the glove and observe the screen at the same time, reducing maintenance time by more than 50%. The glove end and the receiving display end transmit video signals wirelessly. The screen is portable and has a flexible fixing method, which can adapt to various complex environments inside and outside the subway car.

[0024] In some implementations, the camera is attached to the pad of the index finger of the glove and wrapped with a silicone cushioning sleeve.

[0025] Specifically, in this embodiment, the gloves are made of aramid material (thickness ≤ 1.5mm), which is lightweight, heat-insulating (temperature resistance 300℃), and insulating (voltage resistance 500V), making them suitable for various live environments in subway production and manufacturing, regular maintenance and monthly inspections; the camera is an OV2640 model camera (size 5×5×3mm, supports 720P / 30fps), and is fixed to the fingertip of the index finger, offset upward at a 15° angle to avoid the finger obstructing the field of vision, and is protected by a silicone cushioning sleeve on the surface.

[0026] In some implementations, a silicone tube is fitted onto the FPC cable to prevent short circuits caused by metal scratches.

[0027] In some embodiments, the power module includes a first battery compartment and a power management module connected to the first battery compartment. The first battery compartment is located on the inside of the glove's wrist via a Velcro strap and contains a battery for providing 5V power. The power management module is connected to the transmitting module and the first step-down module, respectively.

[0028] Specifically, in this embodiment, the first battery compartment is integrated into the inner side of the glove's wrist, housing an 18650 lithium battery (model: Panasonic NCR18650B, 3.7V / 3400mAh) and equipped with a TP4056 charging module; simultaneously, it uses an HX6003 power management chip with overcharge / over-discharge protection. The first step-down module uses an MP1584EN step-down board (input 4-28V, output 0.8-20V adjustable).

[0029] Furthermore, such as Figure 5 As shown, the GND and BAT pins of the power management chip are connected to the -IN and +IN pins of the step-down module, and also to the GND and VCC pins of the transmitting module. The -OUT and +OUT pins of the step-down module are connected to the GND and 3.3V pins of the camera. The TXD and RXD pins of the camera are connected to the TXD and RXD pins of the transmitting module via an FPC cable.

[0030] In some implementations, the video decoding module uses a Raspberry Pi Zero W controller; The GPIO interface of the video decoding module is connected to the receiving module, and the HDMI interface of the video decoding module is connected to the portable screen. The portable screen is attached to the wall of the subway equipment cabinet or other objects by the four-corner suction cup bracket, which can realize the portable screen.

[0031] Specifically, in this embodiment, the video decoding module decodes the received video data and displays the decoded video on the HDMI screen. The portable screen driver board requires 5V power supply, while the GPIO port of the Raspberry Pi Zero W can only tolerate 3.3V, so it must be stepped down for power supply. The LoRa receiver module shares the 3.3V step-down output with the Raspberry Pi (current requirement <500mA).

[0032] Furthermore, such as Figure 6 As shown, the GPIO15 / TXD and GPIO16 / RXD pins of the video decoding module are connected to the TXD and RXD pins of the receiving module, enabling wireless transmission between the receiving and transmitting modules. The 3.3V and GND pins of the video decoding module are connected to the +OUT and -OUT pins of the step-down module, respectively. The MINI HDMI pin of the video decoding module is connected to the HDMI IN pin of the portable screen. The GPIO2 pin of the video decoding module is also connected to the spare port of the portable screen. The -OUT and +OUT pins of the step-down module are connected to the GND and VCC pins of the receiving module, respectively. The -IN pin of the step-down module and the GND pin of the portable screen are both grounded. The +IN pin of the step-down module and the 5V power supply pin of the portable screen are connected to the 5V power supply.

[0033] Image display design path illustration: Video stream path: Camera → LoRa compression transmission → Raspberry Pi decoding → HDMI screen.

[0034] In some implementations, the transmitting module uses an E32-433T20D LoRa transmitter (433MHz, 2km transmission distance) and is fixed to the forearm strap; The receiving module uses an E32-433T20D LoRa receiver, which is paired with the transmitting module.

[0035] When implementing this using the aforementioned device, the specific operation process is as follows: Step 1: Power on the gloves → The screen is magnetically attached to the wall of the subway equipment cabinet → Automatic pairing and connection; Step 2: Insert your index finger into the mechanical interlayer and push aside the obstruction → locate the component to be inspected and observed → real-time image is displayed on the screen; Step 3: Adjust the screen angle to the optimal viewing angle (the suction cup universal joint supports single-finger operation) and receive video signals at the same time; Video signal: Glove camera → LoRa transmitter module (compressed video stream) → Receiver LoRa module → Raspberry Pi decoder → HDMI output to portable screen.
