[0060] The management method of the maintenance intelligent management system disclosed in the present invention includes the following steps: Step 1, using five positioning nodes to establish a positioning coordinate system in the maintenance hangar, and taking the positioning node at the center point of the maintenance hangar as the positioning origin, that is, the coordinates of the center of the node equipment shell 93 after the positioning node here is unfolded and raised as the positioning origin, and the directions of the positioning origin pointing to the four top corners of the maintenance hangar are respectively used as the X-positive semi-axis direction, Y-positive semi-axis direction, X-negative semi-axis direction and Y-negative semi-axis direction of the positioning coordinate system, and the remaining four positioning nodes are respectively located in the X-positive semi-axis direction, Y-positive semi-axis direction, X-negative semi-axis direction and Y-negative semi-axis direction, and the four quadrants of the positioning coordinate system are respectively used as four positioning intervals.

[0061] Step 2: assign a corresponding wearing mechanism to each positioning interval. The wearing mechanisms in each positioning interval are grouped together. Maintenance personnel of a maintenance team wear the wearing mechanisms belonging to the same group. A power supply module, a video guidance mechanism, a personnel management mechanism, and a maintenance recording mechanism are assembled on each wearing mechanism. After turning on the power switch on the power supply module, the power supply module supplies power to the video guidance mechanism, the personnel management mechanism, and the maintenance recording mechanism, and starts the video guidance mechanism, the personnel management mechanism, and the maintenance recording mechanism.

[0062] Step 3, a wireless communication network is formed by the control cabinet 100, five positioning nodes and various personnel management agencies to implement the real-time positioning step of the maintenance personnel, and selectively implement the maintenance video guidance step and / or the maintenance process recording step, wherein the implementation of the real-time positioning step of the maintenance personnel is specifically as follows: the system administrator wirelessly sends a positioning start command to the five positioning nodes and the personnel management agencies of each wearable device through the control cabinet 100; the personnel management agencies on each wearable device in the positioning interval respectively perform ranging communication with the three positioning nodes corresponding to the positioning interval, that is, the mobile wireless communication module performs wireless communication with the reference wireless communication module, and the reference controllers of the three positioning nodes wirelessly send the signal flight time during the ranging communication to the control cabinet 100 through the reference wireless communication module, and the control cabinet 100 receives the signal from the reference controller. The main controller of the control cabinet 100 uses the signal flight time of the ranging communication to calculate the distance between each personnel management organization and the three positioning nodes corresponding to the positioning interval. This ranging function is a function that the existing wireless communication module itself has, and thus calculates the coordinate position of each personnel management organization in the positioning coordinate system according to the three-point positioning method; the control cabinet 100 determines whether the personnel corresponding to each wearing organization has left the corresponding positioning interval based on the coordinate position of each personnel management organization in the positioning coordinate system, and records the movement trajectory of each personnel; when leaving the corresponding positioning interval, the control cabinet 100 sends an out-of-bounds prompt information to the personnel management organization. After receiving the out-of-bounds prompt information, the mobile controller uses the reminder speaker 25 to give a voice prompt, and at the same time controls the alarm light 9 to flash for a reminder.

[0063] The specific steps for implementing maintenance video guidance are as follows: the system administrator uses the main wireless communication module through the main controller of the control cabinet 100 to send the maintenance guidance video stored in the main memory to the playback wireless communication module of the video guidance mechanism of each wearable device, and the playback controller of the video guidance mechanism receives the maintenance guidance video and stores the maintenance guidance video in the playback memory; the maintenance personnel use the rotation adjustment unit and the telescopic adjustment unit of the video guidance mechanism to adaptively adjust the position and angle of the video playback unit according to usage needs, so that the playback display screen 68 faces a direction that is more convenient for maintenance personnel to watch and does not block normal maintenance work; then the video playback unit is operated and controlled, and the corresponding maintenance guidance video is selected to be played on the playback display screen 68 through the combined operation control of the pause button 70, the play button 71, the forward button 72, and the backward button 73 to provide on-site maintenance guidance to the maintenance personnel.

[0064] The maintenance process recording steps are as follows: the maintenance personnel adjust the pitch angle of the acquisition shell 35 by adjusting the adjustment disk 42 of the pitch positioning unit of the maintenance recording mechanism according to the use requirements, so as to adjust and position the angle of the image acquisition of the camera 36; the maintenance personnel activate the maintenance recording mechanism and turn on or off the fill light 37 by pressing the light button 33 according to the lighting conditions, and the camera 36 and the microphone 97 record and store the video of the maintenance site; after each recording is completed, the maintenance personnel press the send button 34 on the maintenance recording mechanism, and the acquisition controller sends the video stored in the acquisition memory to the main controller of the control cabinet 100 through wireless communication between the acquisition wireless communication module and the main wireless communication module, and the main controller stores the video in the main memory; Step 4. After the daily maintenance task is completed, the system administrator wirelessly sends a positioning shutdown command to the five positioning nodes through the control cabinet 100. The reference controller drives the folding drive mechanism and the lifting drive mechanism of the positioning node to complete the folding and storage of the node device shell 93 of the positioning node, and the protective strip plate 86 is sealed on the strip storage groove 83 for protection. The maintenance personnel disconnect the power supply module of the wearable device and then take off the wearable device.
