Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] This embodiment describes the working process of the utility model according to the maintenance process of the urban sewage pipe network as follows:

[0026] The maintenance team consists of a team leader and several team members, each of whom is required to wear a smart helmet 11, a smart belt 12 and a smart bracelet 13;

[0027] Among them, the smart helmet 11 considers that there is basically no danger of falling objects from high altitude injuring the head according to the working environment, and the working area of ​​the staff is concentrated, and there is no difficulty in communication within the maintenance team, so gas detection devices and cameras are selectively installed. Considering that the urban sewage pipe network is in a closed environment for a long time and domestic sewage is prone to produce gases such as ammonia, hydrogen sulfide and methane, oxygen, methane, ammonia and hydrogen sulfide detection sensors are selected. The detection sensors and cameras adopt modular design. The members of the maintenance team can choose to install different detection sensors and use them together to reduce the weight of the team members' smart helmets 11; the smart belt 12 is equipped with a posture monitoring device and a power supply battery, and first aid equipment is selectively carried. The posture monitoring device can detect whether a person falls; the smart bracelet 12 identifies the personnel composition of the maintenance team through the personnel identification module and sends the personal location. The vital signs detection module monitors the heartbeat, blood oxygen and other signs of the wearer in real time. The smart bracelet 13 is provided with a one-button alarm device. In case of an emergency, the personnel can press the button to make an emergency alarm;

[0028] The team leader of the maintenance team carries the team information relay unit 2, and the smart devices carried by each member of the team are connected to the team information relay unit 2 and reflect real-time information on the team information relay unit 2. The environmental situation preliminary judgment module 22 preliminarily determines whether the environment in the space is suitable for the staff to continue working therein based on the data information reflected by each smart device, and preliminarily determines whether there is an obvious danger in the space based on the image information captured by the camera. The environmental situation preliminary judgment module 22 confirms whether to issue an alarm based on the result of the preliminary judgment;

[0029] The team information relay unit 2 transmits the data information to the environmental situation analysis module 32. The environmental situation analysis module 32 draws the concentration change diagrams of ammonia, methane, hydrogen sulfide and oxygen respectively according to the collected data of multiple data such as the ammonia concentration, methane concentration, hydrogen sulfide concentration and oxygen concentration in the space within a period of time, and predicts the subsequent concentration change trend according to the concentration change diagrams of various gases. According to the predicted concentration change trend, the types of gases that may be dangerous and the time when the danger will occur are calculated, and the predicted situation is transmitted to the team information relay unit 2, so that the maintenance team can arrange the working time reasonably, and the data processing terminal 3 can send out early warning information in advance;

[0030] The environmental situation analysis module 32 further analyzes the risk factors in the image based on the intercepted image information and determines the risk level, such as sharp objects, falling objects that may pose a risk of falling, and assesses the risk level. The risk factors are transmitted to the team information relay unit based on the risk level, and the team leader reports the on-site risk factors and arranges the on-site work activities reasonably. Once the environmental situation analysis module 32 determines that there is an extremely high risk situation on site, the alarm module 33 immediately issues an alarm to the maintenance team and off-site staff at the same time.

[0031] Embodiment 2

[0032] This embodiment describes the working process of the utility model according to the maintenance process in the desulfurization tower of the thermal power industry as follows:

[0033] The maintenance personnel wear the smart helmet 11, smart belt 12 and smart bracelet 13;

[0034] Considering the internal environment and functions of the desulfurization tower, the smart helmet 11 only carries a sulfur dioxide detection sensor and a hydrogen sulfide detection sensor, and the smart belt 12 only carries a posture monitoring device;

[0035] After the maintenance personnel enter the desulfurization tower, the detection sensor regularly detects the gas content in the tower, and the environmental situation preliminary judgment module 22 makes a preliminary judgment on the environmental situation. The environmental situation analysis module 32 draws a gas content change curve based on the gas content detected at each time point, and draws a predicted change trend curve based on the change curve to infer the change trend of the gas in the environment and determine whether it will pose a safety threat to the maintenance personnel at some subsequent time.

[0036] Except for special instructions and further limitation of one preferred or optional technical means as another technical means, the preferred and optional technical means disclosed in the utility model can be arbitrarily combined to form several different technical solutions. Therefore, equivalent changes made according to the claims are still within the scope covered by the utility model.
