[0020] The embodiment of the utility model provides a positioning terminal based on indoor and outdoor fusion positioning.

[0021] See also Figure 1 and Figure 2 , including MCU (micro control unit) 1. The utility model realizes data collection and processing, communication with external devices, and implementation of indoor and outdoor positioning algorithms by writing software programs. By integrating various structural modules, circuit boards 11 and software programs, a practical positioning terminal based on indoor and outdoor fusion positioning is manufactured. The drawing shows that the size of the positioning terminal is 62mm long, 29mm wide, and 95mm high, excluding the antenna.

[0022] Internally, the MCU (microcontroller unit) 1 houses a 4G module 2, a dual-frequency RTK module 3, a UWB module 4, a BDS positioning antenna 5, an indicator light 6, an audible and visual alarm 7, an SOS button 8, an on / off button 9, a battery 10, and a circuit board 11. The core of the positioning device, comprised of the MCU (microcontroller unit) 1, integrates and controls the dual-frequency RTK module 3 and the UWB module 4. RTK Beidou differential positioning is used outdoors, while UWB positioning is used indoors. The two automatically switch seamlessly, helping managers better coordinate and assign work tasks, monitor personnel locations and work progress in real time, and more accurately determine the next work plan. This helps improve work efficiency and avoid wasted time and personnel resources.

[0023] The dual-frequency RTK module 3 obtains Beidou positioning data and verifies the precise position with the local differential base station through the BDS positioning antenna 5. The 4G module 2 transmits the position data to the server in real time. When personnel are outdoors, the setting of the 4G module 2, dual-frequency RTK module 3 and BDS positioning antenna 5 can accurately grasp the personnel's movement trajectory and position, making it easier for administrators to better manage the site.

[0024] The gravity detection module 12 can assist the dual-frequency RTK module 3 in monitoring the position of the staff. The two together locate the position of the staff, which can improve the accuracy of the device positioning and avoid errors in the dual-frequency RTK module 3 that affect the manager's grasp of the work progress. The positioning data recording module 13 can record the positioning data to facilitate the manager to query the positioning data.

[0025] The BeiDou satellite positioning system 14 consists of three parts: the air segment, the ground segment, and the user segment. It can provide high-precision, high-reliability positioning, navigation, and timing services to all types of users around the world, all day and all weather. Through the setting of the BeiDou satellite positioning system 14, the location information of the staff can be transmitted to the BDS positioning antenna 5, facilitating the subsequent positioning monitoring of the positions of indoor and outdoor personnel.

[0026] The UWB module 4 obtains the precise indoor position and transmits the real-time coordinates to the server through UWB wireless pulse technology. When a person is indoors, through the setting of the UWB module 4, the indoor and outdoor boundaries are determined by the distance between the UWB module 4 in the positioning terminal and the indoor UWB positioning base station. Combined with the three-dimensional map information, the indoor and outdoor boundaries are strictly framed. When entering the room, all outdoor positioning data will be discarded and only UWB positioning data will be used. Otherwise, only outdoor Beidou RTK positioning data will be used to achieve precise positioning of indoor and outdoor personnel.

[0027] Indicator light 6 includes a positioning indicator light, a 4G signal indicator light, and a battery indicator light. When in outdoor positioning, the positioning light is always blue, and when in indoor positioning, the positioning light is always red. The 4G signal light is always on, indicating that the data transmission of the 4G module 2 is normal. When the battery is low, the battery light is red.

[0028] The battery 10 is powered by 3.7V DC and has a capacity of 5000mAH. The positioning terminal obtains the position once per second, which can be used continuously by staff for more than 12 hours.

[0029] The current detection module 15 and the alarm module 16 can monitor the current and voltage provided by the battery 10. When the battery 10 is low on power, the current detection module 15 will transmit a signal to the alarm module 16 according to the magnitude of the current. After receiving the signal, the alarm module 16 will sound an alarm to remind the staff that the battery 10 is low on power and needs to be replaced, so as to avoid the low power of the battery 10 affecting the normal operation of the positioning terminal.

[0030] The outer surface of the MCU (microcontroller unit) 1 is fixedly mounted with an audible and visual alarm 7 and an SOS button 8. When the wearer of the integrated positioning terminal is in a dangerous situation, they can long-press the SOS button 8 to call for help. The positioning data uploaded by the positioning terminal is analyzed by the server, and a real-time judgment is made as to whether the location is dangerous. Once a risk is identified, an alarm is issued through the audible and visual alarm 7.

[0031] When the present invention is in use: when the personnel are outdoors, the positioning terminal obtains Beidou positioning data through the dual-frequency RTK module 3, and verifies the precise position with the local differential base station through the BDS positioning antenna 5, and then transmits the position data to the service end in real time through the 4G module 2; when the personnel are indoors, the UWB module 4 obtains the precise indoor position and transmits the real-time coordinates to the service end through UWB wireless pulse technology, realizing seamless connection of high-precision positioning indoors and outdoors, thereby more comprehensively and accurately managing and controlling the workers in the production area, better ensuring the work safety of the relevant personnel, and grasping the position and status of the relevant personnel in real time, so as to provide assistance in emergency situations, which helps to improve work efficiency and avoid waste of time and personnel resources.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
