[0031] In a specific embodiment, the safety state of the worker is monitored, the "human body monitoring" button on the smart bracelet is clicked, the vital sign related data of the worker is read before work as the initial control value. The safety risk range value of the worker is calculated, the smart bracelet is audibly and visually alarmed to display green, and the voice prompt is "vital signs are safe". During continuous monitoring of work, the green light is always on when there is no abnormality, and if the vital signs such as heart rate and respiration are too fast, the vital signs will exceed the safety risk range value, and the red light will be turned on immediately, and the voice prompt "stop work immediately and evacuate" will be given. According to relevant regulations, the single work control is within 60 minutes, and when the worker's working time reaches 55 minutes, the voice prompt "please rest in time and rotate work" is given by the audible and visual alarm.

[0032] In some embodiments, one end of the safety rope 3 is connected to the worker, the other end of the safety rope 3 is connected to the rescue rope device 4, and the force point of the safety rope 3 is located at the middle of the worker's back. When the danger alarm occurs, the rescue rope device 4 pulls the safety rope 3 to quickly pull the worker away from the danger source from the back of the worker. During the pulling process, the worker will not be forced to turn over, can quickly evacuate, and has a certain safety. The rescue rope device 4 is located outside the working space near the exit, and the rescue rope device 4 is connected to the human body monitor 2 through a wireless communication module, so that the rescue rope device 4 can quickly respond to the start of the device when the danger alarm occurs.

[0033] As a preferred embodiment, the rescue rope device 4 is a winch, and the winch is also equipped with a Bluetooth module. A special winch is installed at the safety monitoring site and is connected to the smart bracelet. When the danger alarm occurs, the winch is started synchronously to quickly pull the worker away from the danger source. When the alarm is triggered, the worker is pulled a certain safety distance by the winch, and the specific value is determined according to the risk level, the type of work, and other actual conditions. For example, the winch can be set to pull 5m, or it can be directly pulled to the well mouth or hole, and then the supervisor assists in evacuation.

[0034] As a preferred embodiment, it also includes an emergency rescue slide 5, which is arranged at the exit of the working space, and is used to assist the winch in evacuating the worker.

[0035] For example, the optimal value of the pulling distance of the winch is set as follows: the evacuation pulling distance is set to 5m for short distance, which can quickly escape from the danger source and determine the subsequent situation. For long distance, the evacuation pulling distance is the end point, which is set to the emergency rescue slide 5 below the exit, and then the supervisor on the ground assists in evacuation, which can ensure the safety of the worker and prevent injury during the pulling process.

[0036] As a preferred embodiment, the two side handrails of the emergency rescue slide 5 are in a wavy curve shape, so as to facilitate the workers to exert force and save themselves.

The emergency rescue support 6 is used to erect and support the safety rope 3, and makes the safety rope 3 slide flexibly through the pulley 61, so as to avoid jamming when the rope is collected, and affect the rescue.

[0039] As a preferred embodiment, the bottom of the emergency rescue support 6 is reinforced by the counterweight block 62, which is produced in small specifications and standardized, so as to be convenient to use. The counterweight block 62 can be manually installed and disassembled during operation, and then installed and reinforced at the next operation site, so as to be flexible and convenient to use.

[0040] As a preferred embodiment, the ventilator 7 is further included, which is arranged at the ventilation opening of the working space, and the ventilator 7 is connected with the human body monitor 2 through a wireless communication module. The ventilator 7 is used to ventilate and circulate the limited working space, and timely discharge the toxic gas possibly existing in the space.

[0041] In a specific embodiment, the ventilator 7 cooperates with the gas detector 1. The gas detector 1 is first detached and hung into the working environment, the “ventilation monitoring” button on the smart bracelet is clicked, the ventilator 7 is started synchronously to start the ventilation operation, the ventilator 7 collects the air sample in the limited space, the gas detector 1 detects the air pollutants, after the ventilation time is not less than 30 minutes and the air quality is up to standard, the smart bracelet displays green by sound and light alarm, and the voice prompt is “ventilation state is qualified, air quality is qualified”. The gas detector 1 is reassembled on the protective clothing, and the limited space operation is started. During the subsequent operation, the ventilator 7 circulates to maintain the air quality, the sound and light alarm always displays green under the safe condition, and flashes red to prompt emergency escape when the state is abnormal.
