[0034] In this embodiment, the cooling and dust removal protection component 2 also includes a circulating pump 24, a water supply pipe 25, a cooling coil 26, a heat conduction plate 27, a return pipe 28, and a condenser 29. The circulating pump 24 is fixedly installed on one side of the cooling water storage tank 6, and the suction end of the circulating pump 24 is connected to the cooling water storage tank 6.

The condenser 29 is fixedly installed on the cooling water storage tank 6. The condenser 29 is existing technology and can cool the cooling water, so it is not described in detail here.

[0035] In this embodiment, the battery compartment 5 is electrically connected to the positioning circuit board 4. A sealing ring is provided at the connection between the metal shield 3 and the positioning circuit board 4. A protective baffle is provided on the front side of the positioning circuit board 4. The protective baffle is used to protect the floor signal electrical precision positioning component 1. A detection probe is provided above the sensor.

The dust removal nozzle 23 of the detection probe can remove dust and clean the detection probe during the blowing process.

[0036] In this embodiment, the heat-conducting plate 27 is made of heat-conducting steel, and the cooling coil 26 is serpentine in shape. The cooling and dust removal protection component 2 drives the coolant in the cooling water storage tank 6 through the circulating pump 24, and enters the serpentine cooling coil 26 through the water supply pipe 25. It comes into contact with the heat-conducting plate 27 made of heat-conducting steel, quickly absorbs the heat of the positioning circuit board 4, and then flows back to the water tank through the return pipe 28. The condenser 29 cools the circulating liquid, forming a closed-loop heat dissipation system, replacing the traditional fan heat dissipation, and preventing dust from entering the equipment with the airflow. At the same time, the air pump 21 supplies air to the dust removal nozzle 23 of the detection probe through the gas delivery hard pipe 22, and removes the dust on the surface of the sensor probe in real time, solving the problem of poor detection effect caused by dust accumulation, and ensuring the detection accuracy of components such as the UWB positioning module 11 and the laser range sensor 13.

[0037] In this embodiment, the UWB positioning module 11, RFID reader 12, laser rangefinder 13, and accelerometer 14 are electrically connected to the buzzer 18, and the wireless transmission module 16 is electrically connected to the floor signal display screen 17. The floor signal electrical precision positioning component 1 integrates the UWB positioning module 11, RFID reader 12, laser rangefinder 13, and accelerometer 14.

[0038] Specifically, the cooling and dust removal protection component 2 drives the coolant in the cooling water storage tank 6 through the circulating pump 24, and enters the serpentine cooling coil 26 through the water supply pipe 25. It then comes into contact with the heat-conducting plate 27 made of heat-conducting steel, quickly absorbing the heat from the positioning circuit board 4. The coolant then flows back to the water tank through the return pipe 28. The condenser 29 cools the circulating liquid, forming a closed-loop heat dissipation system that replaces the traditional fan cooling system and prevents dust from entering the equipment with the airflow. At the same time, the air pump 21 supplies air to the dust removal nozzle 23 of the detection probe through the gas delivery rigid pipe 22, which removes the dust on the surface of the sensor probe in real time, solving the problem of poor detection effect caused by dust accumulation and ensuring the detection accuracy of components such as the UWB positioning module 11 and the laser range sensor 13.

[0039] The floor signal electrical precision positioning component 1 integrates a UWB positioning module 11, an RFID reader 12, a laser rangefinder 13, and an accelerometer 14. Through a signal fusion processor 15, it fuses and calculates multi-source signals, combining preset data from the floor parameter storage chip 19 with the absolute position information of the floor RFID tag 20, significantly improving positioning accuracy and avoiding positioning failures caused by single sensor malfunctions, thus meeting high-precision positioning requirements. The metal shield 3 not only reduces the impact of external electromagnetic interference on the positioning circuit board 4, but its sealing ring at the connection point with the positioning circuit board 4 also enhances dust and water resistance. The protective baffle provides physical protection for the floor signal electrical precision positioning component 1, reducing damage to the sensors and circuits from external collisions. The battery compartment 5 provides backup power to ensure continuous operation of the positioning function when the main power is interrupted, further improving equipment reliability.

[0040] The wireless transmission module 16 ensures that the positioning data is stably transmitted to the floor signal display screen 17, providing real-time feedback on the floor location; the UWB positioning module 11, RFID card reader 12 and other sensors are linked with the buzzer 18. When a sensor malfunctions, the buzzer 18 will sound an alarm in time, which will help staff to quickly troubleshoot the fault and ensure the continuous operation of the positioning system.
