[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Example 1: Refer to Figure 1 - Figure 5 As shown: A Beidou intelligent safety helmet with environmental monitoring includes a patrol safety helmet 1, a signal transmission unit 2, and a control terminal 3; The patrol safety helmet 1 is used to determine the position of the operator and conduct safety inspections on the inspection points; The patrol safety helmet 1 includes a positioning unit 4, an environment monitoring unit 5, and a health monitoring unit 6; The positioning unit 4 is used to integrate Beidou positioning, GPS, and GLONASS technologies, combine with a map, and locate the real-time position of the operator, and can quickly and accurately obtain positioning signals under different geographical environments and weather conditions; The environment monitoring unit 5 is used to obtain surrounding environmental parameters through multiple sensors and monitor the surrounding environment of the operator; The environment monitoring unit 5 includes a gas monitoring module 51, a temperature and humidity monitoring module 52, a noise monitoring module 53, a radiation monitoring module 54, an air pressure monitoring module 55, and a light monitoring module 56; The gas monitoring module 51 is used to monitor various gas components and concentrations in the air. The various gases are flammable, explosive, and toxic gases including carbon monoxide, hydrogen sulfide, methane, and ammonia. Gas leakage may trigger serious safety accidents. The gas sensor can issue an alarm in a timely manner when the gas concentration exceeds the standard, and remind the operators to evacuate the dangerous area in a conspicuous way by flashing the induction lamp 14, so as to ensure the safety of personnel. The temperature and humidity monitoring module 52 is used to monitor the temperature and humidity of the environment where the operators are located in real time. Through the temperature and humidity sensor, the changes in the environmental temperature and humidity can be grasped in a timely manner, and corresponding heat prevention and moisture-proof measures can be taken. The noise monitoring module 53 is used to monitor the noise level of the surrounding environment. When the noise exceeds a certain limit, it reminds the staff to take protective measures to protect their hearing health.

[0021] The radiation monitoring module 54 is used to monitor the radiation dose of the surrounding environment in real time. It uses professional radiation detection materials to continuously monitor the radiation dose and feedback the data to the operators and the background management personnel in real time. When the radiation dose exceeds the safety standard, an alarm is immediately issued, and the operators can quickly take protective measures or evacuate the site to avoid being harmed by excessive radiation. The air pressure monitoring module 55 is used to monitor the pressure value of the environment. The abnormal change of the pressure value may indicate the occurrence of a dangerous situation. It captures the pressure change in a timely manner and transmits the information to the operators so that they can make preparations in advance. The light monitoring module 56 is used to monitor the dust content and light intensity in the air. When the visibility is low, it automatically turns on the lighting equipment on the cap. When the light changes abnormally, it indicates that there may be environmental changes or dangers. When the dust concentration exceeds the standard, not only the visibility is reduced, but also the respiratory system of the operators is damaged, and the operators need to be reminded to wear protective equipment.

[0022] The health monitoring unit 6 is used to integrate biosensors to monitor the physical parameters of the operators.

The physiological parameter monitoring module 61 is used to monitor the physical indices of the operators, and the physical indices include heart rate, blood pressure, body temperature and respiration. By obtaining the heart rate data of the operators in real time, the heart rate of a normal adult at rest is 60 - 100 beats per minute. If the heart rate exceeds the normal range, it may indicate that the operator is fatigued, tense, physically uncomfortable or overworked. Regularly or in real time monitor the blood pressure of the operator. The normal blood pressure range is generally 90 - 139 mmHg for systolic pressure and 60 - 89 mmHg for diastolic pressure. If the blood pressure is abnormal, there may be a risk of cardiovascular disease or the body may have a stress response due to factors such as the working environment and labor intensity. Monitor the body temperature of the operator. The normal body temperature of the human body is between 36℃ and 37℃. A too high body temperature may be caused by heatstroke, infection, etc., and a too low body temperature may indicate that the body is in a cold environment or has metabolic abnormalities. Monitor parameters such as respiratory rate and respiratory depth. The respiratory rate of a normal adult at rest is 12 - 20 times per minute. Abnormal respiration may be caused by respiratory system diseases, environmental hypoxia or overwork, etc.; The motion state monitoring module 62 is used to monitor the body posture and motion state of the operators, evaluate the amount of exercise and activity intensity of the operators, judge whether their work load is reasonable, judge whether a fall occurs, and record the motion trajectory of the operators, which can be used to analyze the work path and activity range of the operators. At the same time, it can also quickly determine their location when the personnel are lost or in danger; The mental state monitoring module 63 is used to monitor the degree of eye opening, blink frequency and eye movement of the operators, evaluate their fatigue degree and mental state. Not blinking for a long time or blinking frequently may be manifestations of fatigue or mental tension. When it is detected that the operator shows signs of fatigue, the system will issue a reminder and suggest that the operator take appropriate rest to avoid work mistakes or safety accidents caused by fatigue.

[0027] The safety warning unit 8 includes a range delimitation module 81, a fall and collision alarm module 82 and a risk prediction module 83; The range delimitation module 81 uses two-dimensional and three-dimensional electronic fence technology to set the activity range of the operator. When the operator exceeds the activity range, the alarm mechanism is triggered to prevent the occurrence of safety accidents; The fall and collision alarm module 82 is used to monitor the motion state of the inspection safety helmet 1 and automatically send out an alarm signal when the operator falls and is impacted. The alarm signal conducts multi-level alarms. When the system detects signs of falling and impact, it will first conduct a local alarm and emit a sound and light alarm on the inspection safety helmet 1 to remind the operator that he may be in a dangerous state. At the same time, the relevant data will be transmitted to the background monitoring center in real time, and the management personnel can take further measures according to the specific situation, such as remote voice reminder or arranging rescue personnel to go to the scene.
