[0031] In the maintenance personnel monitoring device disclosed in this utility model, the main controller, reference controller, and mobile controller all adopt existing single-chip microcomputer control modules, such as ARM single-chip microcomputer control modules, to realize the coordinated control of the device; the main wireless communication module, reference wireless communication module, and mobile wireless communication module all adopt existing wireless communication modules, such as ZigBee wireless communication modules, to realize wireless networking communication; the main memory, reference memory, and mobile memory all adopt existing memory modules for data storage; the lifting drive circuit and folding drive circuit all adopt existing stepper motor drive circuits to realize the rotation drive of the lifting drive motor 86 and the folding drive motor 85; and the light switch adopts an existing electronic control switch.

[0032] When using the maintenance personnel monitoring device disclosed in this utility model, the steps are as follows: Step 1, establish a positioning coordinate system in the maintenance hangar using five positioning nodes. Take the positioning node at the center point of the maintenance hangar as the positioning origin, that is, take the coordinates of the positioning node at the center of the unfolded and raised node equipment shell 93 as the positioning origin. Take the directions pointing from the positioning origin to the four corners of the maintenance hangar as the positive X-axis direction, positive Y-axis direction, negative X-axis direction, and negative Y-axis direction of the positioning coordinate system, respectively. The other four positioning nodes are located in the positive X-axis direction, positive Y-axis direction, negative X-axis direction, and negative Y-axis direction, respectively. Take the four quadrants of the positioning coordinate system as four positioning intervals.

[0033] Step 2: Assign a corresponding wearable device to each positioning interval. The wearable devices in each positioning interval are grouped together. A maintenance team wears each wearable device belonging to the same group. Each wearable device is equipped with a power supply module and a personnel management device. After turning on the power supply switch on the power supply module, the power supply module supplies power to the personnel management device and starts the personnel management device.

[0034] Step 3 involves establishing a wireless communication network comprised of control cabinet 100, five positioning nodes, and various personnel management mechanisms to implement real-time positioning of maintenance personnel. Specifically, the system administrator wirelessly sends a positioning start command to the five positioning nodes and the personnel management mechanisms of each wearable device via control cabinet 100. Within the positioning range, the personnel management mechanisms on each wearable device communicate with the three corresponding positioning nodes. This communication involves the mobile wireless communication module communicating with the reference wireless communication module. The reference controllers of the three positioning nodes wirelessly transmit the signal flight time during ranging communication to control cabinet 100 via the reference wireless communication module. The main controller of control cabinet 100 then uses the ranging... The communication signal flight time is used to calculate the distance between each personnel management unit and the three positioning nodes corresponding to the positioning range. This ranging function is a function that the existing wireless communication module itself has. Thus, the coordinate position of each personnel management unit in the positioning coordinate system is calculated according to the three-point positioning method. The control cabinet 100 determines whether the personnel corresponding to each wearable device have left the corresponding positioning range based on the coordinate position of each personnel management unit in the positioning coordinate system. When leaving the corresponding positioning range, the control cabinet 100 sends an out-of-bounds warning message to the personnel management unit. After receiving the out-of-bounds warning message, the mobile controller uses the reminder speaker 25 to make a voice prompt and at the same time controls the alarm light 9 to flash as a reminder.

[0035] Step 4: After the daily maintenance tasks are completed, the system administrator sends a positioning shutdown command wirelessly 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. The protective strip plate 86 covers the strip storage slot 83 for protection. The maintenance personnel disconnect the power supply module of the wearable device and then take off the wearable device.

Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
