Description

Technical Field

[0001] The invention relates to the technical field of live working equipment, and in particular to a temperature field analysis system of live working shielding clothing based on numerical simulation. Background Art

[0002] Electrical shielding clothing is a key equipment to ensure the safety of workers in the power industry. It is mainly used for equipotential work and can effectively shield the electric field. Its material generally contains conductive fibers that can lead the current into the earth. It also has good flame retardancy and wear resistance. This kind of clothing allows workers to safely perform various operations in a high-voltage electric field environment.

[0003] The invention patent with application number 201910676352.1 discloses a multi-dimensional perception information integration system for live working shielding clothing, including an information collection module, an information visualization module, an information transmission module and an information supervision platform; the information collection module includes a vital sign monitoring module, a spatial positioning module, a voice communication module and a video monitoring module; the vital sign monitoring module, the spatial positioning module, the voice communication module, the video monitoring module and the information visualization module are all electrically connected to the information transmission module, and can transmit the vital sign status, spatial position, work point and other information of the live working personnel in real time; the information transmission module and the information supervision platform are electrically connected, and the information transmission module transmits information, and realizes information exchange between equipotential workers and ground workers through the information supervision platform, assisting equipotential workers to carry out work process prompts, danger point notifications, safety distances or violation warnings.

[0004] The application aims to solve the following problems: "It is difficult for traditional shielding clothing to obtain the real-time spatial positioning of the vital signs and typical working positions of workers, and there is a lack of guarantee for the personal and equipment safety during the operation; it is difficult to control whether the safety distance and combined gap between equipotential workers and live objects meet the requirements during the operation, which can easily lead to insufficient safety distance; there is a lack of effective on-site guidance on the work content, operating procedures, and working behaviors of equipotential workers, and the safety of the operation is highly dependent on the skill level of the workers, which can easily lead to incorrect operations; the poles of ultra-high and extra-high voltage transmission lines are high and the tower heads are large in size, and the personnel do not have a good way to communicate, resulting in poor channels for work orders and information feedback, and it is difficult for ground personnel to fully understand the situation at high-altitude work points."

[0005] However, due to the particularity of the use scenarios of existing shielding suits, the strained positions on the surface of each damaged shielding suit have a certain degree of similarity. If these easily strained positions can be strengthened during the production stage of the shielding suit, the service life of the shielding suit can be effectively improved.

[0006] Therefore, a temperature field analysis system for live working shielding clothing based on numerical simulation was proposed. Summary of the invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides a temperature field analysis system for live working shielding clothing based on numerical simulation, which solves the technical problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The temperature field analysis system of live working shielding clothing based on numerical simulation includes:

[0010] The simulation module is used to simulate the scene of dynamic temperature change when the shielding suit is worn; the acquisition module is used to collect the surface temperature field information of the shielding suit; the retrieval module is used to traverse the surface temperature field information of the shielding suit collected by the acquisition module, retrieve part of the information in the surface temperature field information of the shielding suit and forward it to the analysis module; the analysis module is used to receive part of the information in the surface temperature field of the shielding suit retrieved by the retrieval module, and analyze the key positions of the dynamic change of the surface temperature of the shielding suit based on the partial information; the recording module is used to record the key positions of the dynamic change of the surface temperature of the shielding suit analyzed by the analysis module; the reset module is used to control the reset operation of the system; the identification module is used to traverse the key positions of the dynamic change of the surface temperature of the shielding suit recorded in the recording module, and identify the area to be strengthened on the surface of the shielding suit based on the key positions of the dynamic change of the surface temperature of the shielding suit.

[0011] Furthermore, the simulation module is integrated by a human body model, a heating element, and an atomizing element. The heating element and the atomizing element are configured one by one. The mutually configured heating element and the atomizing element are evenly distributed and installed on the surface of the human body model, and the shielding suit is worn on the surface of the human body model.

[0012] The heating element is used to emit heat, and the atomizing element is used to store salt water and spray the salt water in the form of atomization. The heat emitted by the heating element and the spray size of the atomized water are both controllable. The surface of the shielding suit worn by the human model is evenly distributed with temperature sensors installed;

[0013] The salt-to-water ratio of brine is 0.9% to 1.2%.

[0014] Furthermore, the simulation module is provided with submodules at the lower level, including:

[0015] The control platform is used to select and control the operation of the heating element, atomizing element and shielding suit surface temperature sensor in the simulation module;

[0016] The control platform is integrated by computer equipment, and a three-dimensional model of a human body model is stored in the computer platform. The distribution positions of heating elements and atomizing elements are synchronously marked on the surface of the three-dimensional model. The system end user clicks on the distribution positions of the heating elements and atomizing elements marked on the three-dimensional model of the human body model, that is, the operation of selecting the corresponding heating elements and atomizing elements, and further sets the temperature, the salt water atomization spraying efficiency and the running time of the selected heating elements and atomizing elements in the control platform;

[0017] Among them, temperature sensors are installed on the surface of the simulation module, control platform and shielding suit. The three parties perform data interaction operations through the local area network. The control results of the control platform and the dynamic temperature change scene of the shielding suit wearing state simulated by the simulation module. Before the control platform controls the operation, the system end user customizes the posture of the human model wearing the shielding suit.

[0018] Furthermore, the surface temperature field information of the shielding suit collected by the acquisition module is a collection of temperature information sensed by each group of temperature sensors installed on the surface of the shielding suit, and the temperature sensors continuously operate in the simulation module operation state based on the specified operating frequency to sense the position information;

[0019] The acquisition module is internally provided with submodules, including:

[0020] A storage unit, used for receiving the surface temperature field information of the shielding suit collected by the collection module;

[0021] When the storage unit stores the surface temperature field information of the shielding suit, it marks it based on the temperature information perception timestamp, and after completing the marking, it distinguishes and stores it based on the temperature sensor that is the source of the temperature information.

[0022] Furthermore, the retrieval module runs continuously, and each time the retrieval module runs, part of the information of the surface temperature field of the shielding suit is retrieved from a differentiated storage interval in the storage unit;

[0023] The analysis module is provided with submodules at the lower level, including:

[0024] A setting unit is used to set the temperature variation range;

[0025] A capture unit is used to obtain part of the information received by the analysis module, analyze the temperature variation trend based on the obtained part of the information, and further capture the part of the information source that meets the temperature variation interval of the temperature variation interval analysis result to distinguish the storage interval;

[0026] Among them, the temperature variation interval set in the setting unit is customized by the system user, and the temperature variation area is a threshold. After capturing the differentiated storage intervals, the capture module further identifies the temperature sensors corresponding to each differentiated storage interval. The area defined on the surface of the shielding suit by each identified temperature sensor is the key position of the dynamic change of the surface temperature of the shielding suit.

[0027] Furthermore, the analysis logic of the temperature change situation in the capture unit is expressed as:

[0028]

[0029] Where: θ is the temperature variation trend value reflected by a temperature sensor; n is the total amount of temperature information in the partial information retrieved by the retrieval module once; C i is the temperature value represented by the i-th temperature information based on the time series; is the average temperature value; C MAX is the maximum temperature value among n; C MIN is the minimum temperature value among n; α is the adjustment coefficient, which is used to balance the influence of temperature fluctuation amplitude on temperature variation trend; w i (t) is a dynamic weight factor, which changes with time t and is used to adjust the contribution of each temperature value to the temperature variation trend; γ is the coefficient for adjusting the influence of temperature deviation from the average value on the weight; β is the coefficient for adjusting the influence of temperature change rate on the weight; is the time derivative of the ith temperature value; C i-1 is the temperature value represented by the i-1th temperature information based on the time series; Δt is the time interval, which represents the acquisition time difference between two adjacent temperature values;

[0030] Among them, the larger the θ is, the greater the temperature change at the surface of the shielding suit where the temperature sensor is located, and vice versa, the smaller the temperature change at the surface of the shielding suit where the temperature sensor is located.

[0031] Furthermore, during the operation phase of the recording module, the temperature sensors analyzed by the analysis module are acquired, and the positions of the temperature sensors and the surface of the shielding suit are further acquired. A closed area is obtained based on the adjacent connection of each acquired position. The local area of ​​the shielding suit surface corresponding to the closed area is the key position of the dynamic change of the shielding suit surface temperature.

[0032] Furthermore, the reset module controls the system to reset at least once. When the reset module controls the system to reset, the simulation content of the temperature dynamic change scene when the shielding suit is worn by the simulation module does not change, and the posture of the human model wearing the shielding suit is adjusted by the system user.

[0033] Furthermore, the reset module controls the number of times the system resets the operation to comply with:

[0034] When the reset module controls the system to reset and operate, the modules in the system operate continuously, so that the recording module has different key positions of the dynamic changes in the surface temperature of the shielding suit based on the system operation records. When there is an intersection between the key positions of the dynamic changes in the surface temperature of the shielding suit recorded in the recording module, the reset module no longer controls the system to reset and operate, and uses the intersection of the key positions of the dynamic changes in the surface temperature of the shielding suit as the area to be strengthened on the surface of the shielding suit identified by the identification module.

[0035] Furthermore, the simulation module is interactively connected to a control platform through a wireless network at its lower level, the simulation module is interactively connected to a collection module through a wireless network, the collection module is interactively connected to a storage unit through a wireless network, the collection module is interactively connected to a retrieval module and an analysis module through a wireless network, the analysis module is interactively connected to a setting unit and a capture unit through a wireless network at its lower level, and the analysis module is interactively connected to a recording module, a reset module and an identification module through a wireless network.

[0036] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0037] The present invention provides a temperature field analysis system for live working shielding clothing based on numerical simulation. During operation, the system simulates the life loss of the shielding clothing caused by sweating of the workers when the shielding clothing is worn in a working state in a numerical simulation manner. Therefore, during the simulation process, the area to be strengthened on the surface of the shielding clothing is identified by sensing the surface temperature parameters of the shielding clothing, so as to provide the production process of the shielding clothing, and adaptively strengthen the area to be strengthened. Therefore, through the strengthening treatment of specific areas on the surface of the shielding clothing, the service life of the shielding clothing in the subsequent use process is effectively extended, and the safety of the shielding clothing is improved to a certain extent.

[0045] The simulation module is integrated with a human body model, a heating element, and an atomizing element. The heating element and the atomizing element are configured one by one. The mutually configured heating element and the atomizing element are evenly distributed and installed on the surface of the human body model, and the shielding suit is worn on the surface of the human body model.

[0046] The heating element is used to emit heat, and the atomizing element is used to store salt water and spray the salt water in the form of atomization. The heat emitted by the heating element and the spray size of the atomized water are both controllable. The surface of the shielding suit worn by the human model is evenly distributed with temperature sensors installed;

[0047] Among them, the salt-to-water ratio of the brine is 0.9% to 1.2%;

[0048] Through the above settings, the state of the shielding suit when worn by the staff can be simulated more realistically, thereby improving the accuracy of the collection module in the system in collecting the surface temperature field information of the shielding suit.

[0049] The simulation module is equipped with sub-modules, including:

[0050] The control platform is used to select and control the operation of the heating element, atomizing element and shielding suit surface temperature sensor in the simulation module;

[0051] The control platform is integrated by computer equipment. The computer platform stores a three-dimensional model of the human body model. The distribution positions of the heating elements and the atomizing elements are synchronously marked on the surface of the three-dimensional model. The system end user clicks on the distribution positions of the heating elements and the atomizing elements marked on the three-dimensional model of the human body model, that is, the operation of selecting the corresponding heating elements and the atomizing elements. The temperature of the selected heating elements and the atomizing elements, the salt water atomization spraying efficiency and the operating time are further set in the control platform.

[0052] Among them, the simulation module, control platform and shielding suit surface are equipped with temperature sensors. The three parties perform data interaction through the local area network. The control results of the control platform and the dynamic temperature change scene of the shielding suit wearing state simulated by the simulation module. Before the control platform controls the operation, the system end user customizes the posture of the human model wearing the shielding suit.

[0053] A collection module is used to collect the surface temperature field information of the shielding suit;

[0054] The surface temperature field information of the shielding suit collected by the acquisition module is a collection of temperature information sensed by each group of temperature sensors installed on the surface of the shielding suit. The temperature sensors continuously operate under the simulation module operation state based on the specified operating frequency to sense the position information;

[0055] The acquisition module is internally provided with submodules, including:

[0056] A storage unit, used for receiving the surface temperature field information of the shielding suit collected by the collection module;

[0057] When the storage unit stores the surface temperature field information of the shielding suit, it marks it based on the temperature information perception timestamp, and after the marking is completed, it distinguishes and stores it based on the temperature sensor from which the temperature information comes;

[0058] The retrieving module is used to traverse the shielding suit surface temperature field information collected by the collecting module, retrieve part of the shielding suit surface temperature field information and forward it to the analyzing module;

[0059] The retrieval module runs continuously, and each time the retrieval module runs, part of the information of the surface temperature field of the shielding suit is retrieved from a separate storage interval in the storage unit;

[0060] The analysis module is provided with submodules, including:

[0061] A setting unit is used to set the temperature variation range;

[0062] A capture unit is used to obtain part of the information received by the analysis module, analyze the temperature variation trend based on the obtained part of the information, and further capture the part of the information source that meets the temperature variation interval of the temperature variation interval analysis result to distinguish the storage interval;

[0063] The temperature variation interval set in the setting unit is customized by the system end user, and the temperature variation area is a threshold. After capturing the differentiated storage intervals, the capture module further identifies the temperature sensors corresponding to each differentiated storage interval. Each identified temperature sensor is in a defined area on the surface of the shielding suit, that is, a key position for the dynamic change of the surface temperature of the shielding suit.

[0064] An analysis module is used to receive partial information of the surface temperature field of the shielding suit retrieved by the retrieval module, and analyze key positions of the dynamic change of the surface temperature of the shielding suit based on the partial information;

[0065] The analysis logic of the temperature variation trend in the capture unit is expressed as:

[0066]

[0067] Where: θ is the temperature variation trend value reflected by a temperature sensor; n is the total amount of temperature information in the partial information retrieved by the retrieval module once; C i is the temperature value represented by the i-th temperature information based on the time series; is the average temperature value; C MAX is the maximum temperature value among n; C MIN is the minimum temperature value among n; α is the adjustment coefficient, which is used to balance the influence of temperature fluctuation amplitude on temperature variation trend; w i (t) is a dynamic weight factor, which changes with time t and is used to adjust the contribution of each temperature value to the temperature variation trend; γ is the coefficient for adjusting the influence of temperature deviation from the average value on the weight; β is the coefficient for adjusting the influence of temperature change rate on the weight; is the time derivative of the ith temperature value; C i-1 is the temperature value represented by the i-1th temperature information based on the time series; Δt is the time interval, which represents the acquisition time difference between two adjacent temperature values;

[0068] Among them, the larger the θ is, the greater the temperature change at the surface of the shielding suit where the temperature sensor is located, and vice versa, the smaller the temperature change at the surface of the shielding suit where the temperature sensor is located;

[0069] Through the above formula, the analysis logic of the temperature change trend in the capture unit is limited, thereby providing necessary data support for the operation of the system in this embodiment to identify the area on the surface of the shielding suit to be strengthened, so as to ensure stable output of the area on the surface of the shielding suit to be strengthened.

[0070] A recording module is used to record the key positions of the dynamic changes in the surface temperature of the shielding suit analyzed by the analysis module;

[0071] Reset module, used to control system reset operation;

[0072] An identification module is used to traverse the key positions of the dynamic change of the surface temperature of the shielding suit recorded in the recording module, and identify the area to be strengthened on the surface of the shielding suit based on the key positions of the dynamic change of the surface temperature of the shielding suit;

[0073] The reset module controls the number of times the system resets operations according to:

[0074] When the reset module controls the system to reset and run, the modules in the system run continuously, so that the recording module has different key positions of the dynamic change of the surface temperature of the shielding suit based on the system operation records each time. When there is an intersection between the key positions of the dynamic change of the surface temperature of the shielding suit recorded in the recording module each time, the reset module no longer controls the system to reset and run, and uses the intersection of the key positions of the dynamic change of the surface temperature of the shielding suit as the area to be strengthened on the surface of the shielding suit identified by the identification module;

[0075] The simulation module is interactively connected to a control platform through a wireless network at its lower level, the simulation module is interactively connected to a collection module through a wireless network, the collection module is interactively connected to a storage unit through a wireless network, the collection module is interactively connected to a retrieval module and an analysis module through a wireless network, the analysis module is interactively connected to a setting unit and a capture unit through a wireless network at its lower level, and the analysis module is interactively connected to a recording module, a reset module and an identification module through a wireless network.

[0076] In this embodiment, the simulation module runs to simulate the temperature dynamic change scene when the shielding suit is worn, the control platform synchronously selects and controls the operation of the heating element, the atomizing element and the shielding suit surface temperature sensor in the simulation module, the acquisition module runs to collect the shielding suit surface temperature field information, the storage unit synchronously receives the shielding suit surface temperature field information collected by the acquisition module, the retrieval module is further used to traverse the shielding suit surface temperature field information collected by the acquisition module, retrieve part of the shielding suit surface temperature field information and forward it to the analysis module, the setting unit synchronously sets the temperature variation interval, the capture unit obtains part of the information received by the analysis module in real time, and based on the acquired information Partial information is used to analyze the temperature variation trend, and the partial information source that meets the temperature variation interval is further captured and stored in the analysis result. The analysis module then receives partial information in the surface temperature field of the shielding suit retrieved by the calling module, and analyzes the key positions of the dynamic changes of the surface temperature of the shielding suit based on the partial information. The recording module runs the key positions of the dynamic changes of the surface temperature of the shielding suit analyzed by the recording module. The reset module controls the system to reset in real time. Finally, the recognition module traverses the key positions of the dynamic changes of the surface temperature of the shielding suit recorded in the recording module, and identifies the areas on the surface of the shielding suit to be strengthened based on the key positions of the dynamic changes of the surface temperature of the shielding suit.

[0077] Through the operation of the system in the above embodiment, the shielding suit is provided with temperature field analysis and processing, thereby identifying the positions on the surface of the shielding suit that are prone to wear and tear, and further in the production stage of the shielding suit, the shielding suit is subjected to targeted strengthening treatment based on the identified positions that are prone to wear and tear, thereby achieving the effect of improving the service life and safety of the shielding suit.

[0078] like Figure 1 As shown, during the operation phase of the recording module, each temperature sensor analyzed by the analysis module is obtained, and the position of each temperature sensor and the surface of the shielding suit is further obtained, and a closed area is obtained based on the adjacent connection of each obtained position. The local area of ​​the shielding suit surface corresponding to the closed area is the key position of the dynamic change of the surface temperature of the shielding suit;

[0079] The reset module control system resets its operation at least once. When the reset module control system resets its operation, the simulation module's simulation content of the scene of dynamic temperature changes when the shielding suit is worn does not change, and the posture of the human model wearing the shielding suit is adjusted by the system user.

[0080] Through the above settings, further operation data support is provided for the operation of the system in the above embodiments, ensuring that the system in the above embodiments can operate more stably and providing more effective performance improvement for the shielding suit.

[0081] In summary, during operation, the system in the above embodiment simulates the loss of life of the shielding suit caused by sweating when the shielding suit is worn in a working state by means of numerical simulation. Therefore, during the simulation, the surface temperature parameters of the shielding suit are sensed to identify the area to be strengthened on the surface of the shielding suit, so as to provide the production process of the shielding suit, and adaptively strengthen the area to be strengthened. Therefore, through the strengthening treatment of specific areas on the surface of the shielding suit, the service life of the shielding suit in subsequent use is effectively extended, and the safety of the shielding suit is improved to a certain extent.
