Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] like Figure 1 As shown, the virtual visualization space safety management and control system for power transmission and transformation construction proposed by the present invention includes a management and control platform, a construction environment analysis module, a construction personnel supervision module, an equipment operation analysis module, an early warning module, a data visualization module and a virtual reality device;

[0047] The control platform is connected to the data visualization module, the construction environment analysis module and the equipment operation analysis module in two-way communication. The control platform is connected to the construction personnel supervision module, the virtual reality equipment and the early warning module in one-way communication. The construction personnel supervision module is connected to the early warning module in one-way communication, and the early warning module is connected to the virtual reality equipment in one-way communication.

[0048] The construction environment analysis module collects statistics on the construction environment information of the construction site and evaluates and analyzes the construction environment based on the construction environment information. The construction environment information includes the humidity, temperature and wind speed of the construction site;

[0049] The construction environment analysis module is used to collect statistics on the construction environment information of the construction site:

[0050] The construction environment analysis module collects construction environment information through the sensor matrix at fixed intervals, and compares the collected construction environment information with the preset standard environment information. If the real-time construction humidity is within the preset standard construction humidity, it is recorded as a qualified construction humidity data point; if the real-time construction humidity is outside the preset standard construction humidity, it is recorded as an unqualified construction humidity data point; if the real-time construction temperature is within the preset standard construction temperature, it is recorded as a qualified construction temperature data point; if the real-time construction temperature is outside the preset standard construction temperature, it is recorded as an unqualified construction temperature data point; if the real-time construction wind speed is within the preset standard construction wind speed, it is recorded as a qualified construction wind speed data point; if the real-time construction wind speed is outside the preset standard construction wind speed, it is recorded as an unqualified construction wind speed data point;

[0051] The method by which the construction environment analysis module evaluates and analyzes the construction environment based on the construction environment information is as follows:

[0052] The construction environment analysis module calculates the qualified data points and unqualified data points of the construction humidity, obtains the proportion of qualified data points in the total data points, and records them as the construction humidity qualified rate, where the total data points are the sum of qualified data points and unqualified data points. The construction environment analysis module compares and analyzes the construction humidity qualified rate with the preset construction humidity qualified rate threshold value stored in its internal input. If the construction humidity qualified rate is greater than or equal to the preset construction humidity qualified rate threshold value, a construction humidity qualified signal is generated. If the construction humidity qualified rate is less than the preset construction humidity qualified rate threshold value, a construction humidity unqualified signal is generated. The humidity unqualified signal indicates that the humidity at the construction site is not conducive to the normal progress of the construction work, and the humidity at the construction site will affect the insulation performance of the equipment, the safe operation of the equipment, the construction efficiency and the quality.

[0053] The construction environment analysis module obtains the proportion of qualified data points in the total data points in the construction temperature, and records it as the construction temperature qualified rate, where the total data points are the sum of qualified data points and unqualified data points. The construction environment analysis module compares and analyzes the construction temperature qualified rate with the preset construction temperature qualified rate threshold value stored in its internal input. If the construction temperature qualified rate is greater than or equal to the preset construction temperature qualified rate threshold value, a construction temperature qualified signal is generated. If the construction temperature qualified rate is less than the preset construction temperature qualified rate threshold value, a construction temperature unqualified signal is generated. The construction temperature unqualified signal indicates that the temperature at the construction site is not conducive to the normal progress of the construction work, and the temperature at the construction site will affect the safety of construction personnel, equipment performance and construction quality.

[0054] The construction environment analysis module obtains the proportion of qualified construction wind speed data points in the total data points and records it as the construction wind speed qualified rate, where the total data points are the sum of qualified data points and unqualified data points. The construction environment analysis module compares and analyzes the construction wind speed qualified rate with the preset construction wind speed qualified rate threshold value stored in its internal input. If the construction wind speed qualified rate is greater than or equal to the preset construction wind speed qualified rate threshold value, a construction wind speed qualified signal is generated. If the construction wind speed qualified rate is less than the preset construction wind speed qualified rate threshold value, a construction wind speed unqualified signal is generated. The construction wind speed unqualified signal indicates that the wind speed at the construction site is not conducive to the normal progress of the construction work, and the wind speed at the construction site will affect the construction safety, construction quality and construction progress.

[0055] The construction environment analysis module sends the unqualified construction humidity signal, unqualified construction temperature signal and unqualified construction wind speed signal to the early warning module through the management and control platform;

[0056] After receiving the warning signal of unqualified construction humidity, unqualified construction temperature and unqualified construction wind speed, the management personnel will promptly make reasonable adjustments to the construction time, strengthen the safety protection measures for the construction personnel and strengthen the maintenance and repair of the equipment on the construction site, effectively ensuring the normal progress of the power transmission and transformation construction project and significantly reducing the impact of the construction environment on the power transmission and transformation construction project;

[0057] The construction worker supervision module supervises, evaluates and analyzes the physical condition information of construction workers, including their heart rate, sweat secretion and body temperature;

[0058] The supervision, evaluation and analysis process of the construction personnel supervision module on the real-time physical condition of the construction personnel is as follows:

[0059] The heart rate multiplier values ​​of the construction workers in multiple time periods are obtained. The abnormal heart rate multiplier value represents the ratio of the area enclosed by the line segment of the heart rate characteristic curve located above the preset heart rate characteristic curve and the preset heart rate characteristic curve to the area enclosed by the heart rate characteristic curve and the X-axis. In this way, a set A of heart rate multiplier values ​​is constructed, and then the maximum subset and the minimum subset in the set A are obtained. The mean of the difference between the maximum subset and the minimum subset in the set A is recorded as the abnormal heart rate risk value XYF. The larger the value of the abnormal heart rate risk value XYF is, the more abnormal the heart rate of the construction workers is, and the greater the safety risk of the construction workers is.

[0060] The sweat secretion of the construction workers detected in multiple time periods is obtained to construct a set B of sweat secretion, the mean in the set B is obtained, and the mean in the set B is marked as the sweat secretion mean, a rectangular coordinate system is established with time as the X-axis and the sweat secretion mean as the Y-axis, a sweat secretion mean curve is drawn by plotting points, and a preset sweat secretion mean threshold curve is drawn in the coordinate system at the same time, and the product value obtained by normalizing the data of the time corresponding to the line segment above the preset sweat secretion mean threshold curve and the area enclosed by the upper line segment and the preset sweat secretion mean threshold curve is obtained from the coordinate system, and it is marked as the abnormal sweating risk value CYF. The larger the value of the abnormal sweating risk value CYF, the more abnormal the sweat secretion of the construction workers is, and the greater the safety risk of the construction workers is;

[0061] The body temperatures of construction workers detected in multiple time periods are obtained, and the difference between the body temperatures of two consecutive time periods is obtained. The average of the difference between the body temperatures of the two consecutive time periods is marked as the body temperature change value. A rectangular coordinate system is established with time as the X-axis and the body temperature change value as the Y-axis. The body temperature change value curve is drawn by plotting points. At the same time, a preset body temperature change value threshold curve is drawn in the coordinate system. The acute angle value formed when the body temperature change value curve intersects with the preset body temperature change value threshold curve for the first time is obtained from the coordinate system, and it is marked as the abnormal body temperature risk angle TYF. The larger the value of the abnormal body temperature risk angle TYF, the more abnormal the body temperature change of the construction worker is, and the greater the safety risk of the construction worker is.

[0062] By formula The physical condition assessment coefficient is obtained, where b1, b2 and b3 are respectively the preset proportional factor coefficients of the abnormal heart rate risk value, abnormal sweating risk value and abnormal body temperature risk angle, and e is a natural constant. The physical condition assessment coefficient SSZ is compared and analyzed with the preset physical condition assessment coefficient threshold value stored in the internal input:

[0063] If the physical condition assessment coefficient SSZ is greater than or equal to the preset physical condition assessment coefficient threshold, a warning signal is generated and sent to the early warning module;

[0064] If the physical condition assessment coefficient SSZ is less than the preset physical condition assessment coefficient threshold, no signal is generated;

[0065] After receiving the alarm signal, the management personnel immediately arranged for the construction workers to stop work and send them to the hospital for examination, effectively ensuring the safety of the construction workers during construction, avoiding personnel safety accidents in the power transmission and transformation project, and ensuring the safe progress of the power transmission and transformation project.
