Description

Technical Field

[0001] The present invention relates to the technical field of chamber environment monitoring, and in particular to a method and system for monitoring a chamber construction environment. Background Art

[0002] A chamber is an underground tunnel with three axes of similar length that does not directly connect to the ground, such as a winch house, a substation, a coal bunker, etc. Due to the special space and geographical environment of the chamber, the construction risk is relatively high. Therefore, during the construction of the chamber, it is necessary to monitor the concentration of oxygen, combustible gas, hydrogen sulfide and carbon monoxide in the chamber at all times to ensure the safety of the workers in the chamber.

[0003] The existing monitoring of the construction environment in the cavern mainly involves the deployment of gas detection probes at different sections of the tunnel and at different locations of the sections to collect changes in the concentration of various harmful gases in real time. The harmful gas monitoring data is wirelessly transmitted to the duty room at the entrance of the cavern, which displays and records changes in the concentration of harmful gases. When the monitoring finds that the concentration of harmful gases exceeds the standard, the harmful gas probes in the cavern will automatically sound and light alarms to remind the workers in the cavern to evacuate. However, due to the uneven distribution of gas in the cavern, the limited number of gas detection probes, the limited monitoring range, and the low timeliness of installation, the accuracy of the cavern environment monitoring data is low, which cannot meet the needs of comprehensive protection of the safety of workers. Summary of the invention

[0054] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0055] The accuracy of the chamber environment monitoring data is low and cannot meet the need for comprehensive protection of the safety of workers. The embodiment of the present invention provides a method for monitoring the construction environment of a chamber, such as Figure 1 As shown, the method includes:

[0056] 101. Acquire monitoring data of at least one wearable monitoring device and electromagnetic wave signal transmission data between the wearable monitoring device and the wireless access point through a wireless access point arranged in a target chamber.

[0057] In an embodiment of the present invention, the target chamber is a chamber where construction work is in progress, and a wireless access point is installed in the space of the chamber. The wireless access point is a wireless transmitting and receiving device, which is used to receive monitoring data collected by a wearable monitoring device in the chamber, and feed the monitoring data back to the server of the monitoring system. Each operator working in the target chamber carries a wearable monitoring device, that is, the wearable monitoring device is carried one-to-one by the operator in the target chamber. This wearable monitoring device is used to collect environmental sampling data of the environment surrounding the operator, as well as the vital signs sampling data of the corresponding operator, that is, the monitoring data includes environmental sampling data of the operator's location and vital signs sampling data of the operator.

[0058] It should be noted that the wearable monitoring device can be a wearable device, such as a bracelet, a head-mounted device, etc. Wearing the wearable monitoring device will not affect the construction actions of the operators, and at the same time, it realizes mobile monitoring of the indoor environment of the cave, greatly improving the scope of environmental monitoring, and the collected environmental data is the actual environment of the operators, thereby greatly improving the accuracy of environmental data sampling.

[0059] 102. Determine the location point information corresponding to the wearable monitoring device according to the electromagnetic wave signal transmission data.

[0060] In the embodiment of the present invention, the wireless access point can also transmit electromagnetic waves to the wearable monitoring device, and determine the distance between the operator and the wireless access point according to the intensity of the electromagnetic waves after being refracted back, and then determine the location information of the operator in the chamber. The chamber is located underground and the space is small. Conventional GPS positioning cannot accurately obtain the location information of the operator. The wearable monitoring device is positioned through the transmission characteristics of the electromagnetic wave signal between the wireless access point and the wearable monitoring device, which not only ensures the accuracy of the positioning, but also does not need to add other positioning devices, thereby improving the utilization rate of the equipment.

[0061] 103. Determine the single-point construction environment monitoring results at different locations based on the monitoring data.

[0062] In an embodiment of the present invention, the environmental monitoring results of the location point where each wearable monitoring device is located are determined based on the environmental sampling data and vital sign sampling data collected by each wearable monitoring device. Specifically, the environmental monitoring results of the current location point can be determined based on the threshold judgment results of each environmental sampling data and the threshold judgment results of each vital sign sampling data. Among them, the environmental sampling data includes but is not limited to temperature, humidity, oxygen concentration, combustible gas concentration, sulfur dioxide gas concentration, nitrogen dioxide gas concentration, nitrogen oxides, carbon dioxide concentration, environmental pollution index (PM2.5), dust, and noise. The vital sign sampling data includes but is not limited to blood pressure, body temperature, blood oxygen, and heart rate.

[0063] It should be noted that the ultimate goal of chamber environment monitoring is to protect the safety of workers. The gas composition in the chamber is complex. When all environmental sampling data are within the threshold range, workers may still feel unwell. If we simply judge the environmental sampling data, we cannot know the impact of the chamber environment on the physical condition of the workers. By combining environmental sampling data and vital signs sampling data to jointly judge the environmental monitoring results, we can more accurately determine the current environmental conditions, thereby improving the accuracy of environmental monitoring.

[0064] 104. Generate a global construction environment monitoring result of the target chamber based on the location point information, the single-point construction environment monitoring result and the monitoring data.

[0065] In the embodiment of the present invention, the single-point construction environment monitoring result may include abnormal state and normal state, and the abnormal state may include general abnormal state, emergency abnormal state, and alarm state, which are not specifically limited in the embodiment of the present invention. The information of different location points is combined with the corresponding single-point construction environment monitoring results to obtain the environmental monitoring status and environmental monitoring data of multiple location points in the target chamber, so as to evaluate the overall environmental conditions in the target chamber according to the distribution of the environmental monitoring status and environmental monitoring data in the spatial position, and obtain the global construction environment monitoring results.

[0066] In an embodiment of the present invention, for further explanation and limitation, as Figure 2 As shown, step 102 determines the single-point construction environment monitoring results at different locations based on the monitoring data, including:

[0067] 201. For each of the location points, identify each item of data in the environmental sampling data according to a single identification strategy to determine a plurality of single environmental data identification results.

[0068] 202. When any of the single environmental data identification results is abnormal, determine that the single-point construction environment monitoring result of the corresponding location point is abnormal.

[0069] 203. When all the identification results of the single environmental data are normal, the monitoring data is re-identified according to the joint identification strategy to determine at least one joint identification result.

[0070] 204. If any of the joint identification results is abnormal, determine that the single-point construction environment monitoring result of the location point is abnormal.

[0071] In an embodiment of the present invention, for the environmental sampling data of each location point, each item of data therein is identified separately according to a single identification strategy to obtain an identification result of whether each item of data is normal or abnormal, that is, a single environmental data identification result. Among them, the single identification strategy can be a threshold comparison strategy. For example, if the volume concentration of oxygen does not meet the range of (19.5%-23.5%), the concentration of combustible gas is greater than 10% of the lower explosion limit, the concentration of hydrogen sulfide gas is greater than 10mg / m3, and the concentration of carbon monoxide gas is greater than 30mg / m3, then the single environmental data identification result can be directly determined to be abnormal.

[0072] When all the identification results of individual environmental data are normal, it cannot be completely ensured that the current environment does not pose a threat to the safety of the workers. In order to further refine the single-point construction environment monitoring results, the monitoring data is secondary identified in accordance with the joint identification strategy to obtain at least one joint identification result. Among them, the joint identification strategy includes a vital signs joint sub-strategy and / or an operation time joint sub-strategy. The vital signs joint sub-strategy is a strategy for jointly identifying one or more vital signs data with one or more environmental sampling data. The operation time joint sub-strategy is a strategy for jointly identifying one or more environmental sampling data with the operation time of the workers. Through the joint identification strategy, environmental risks can be monitored from the dimensions of the actual impact of the environment on the vital signs of workers and the cumulative impact of the environment on the time of workers, thereby improving the accuracy of environmental monitoring.

[0073] The number of vital sign items in the combined vital sign data and the number of environmental data items in the environmental sampling data can be customized according to actual needs. For example, body temperature, blood pressure and oxygen concentration are jointly identified; heart rate and oxygen concentration, carbon monoxide concentration are jointly identified; blood pressure, blood oxygen and carbon dioxide concentration, sulfur dioxide concentration are jointly identified, etc. The embodiment of the present invention does not specifically limit the content and quantity of the jointly identified data.

[0074] In one embodiment of the present invention, for further explanation and limitation, performing secondary recognition on monitoring data according to the vital sign joint sub-strategy to determine at least one joint recognition result includes:

[0075] For any life-environment association combination, if the vital sign data does not meet the corresponding vital sign conditions and the environmental data does not meet the corresponding associated environmental conditions, the corresponding joint recognition result is determined to be abnormal.

[0076] In the embodiment of the present invention, the life environment associated combination includes at least one of a temperature and body temperature combination, a temperature and heart rate combination, a temperature and blood pressure combination, a humidity and body temperature combination, a humidity and blood oxygen combination, an oxygen and blood oxygen combination, an oxygen and heart rate combination, a carbon dioxide and blood pressure combination, a pollution index and blood oxygen combination, a pollution index and heart rate combination, and a noise and blood pressure combination. Each life environment associated combination corresponds to at least one set of judgment conditions. The specific conditions can be set with reference to the following conditions, or they can be customized, and the embodiment of the present invention does not make specific restrictions. If the ambient temperature exceeds 30°C (associated environment conditions), the body temperature exceeds 36°C and there is still an upward trend (vital sign conditions), the joint recognition result is abnormal, otherwise it is normal. If the ambient temperature is lower than 16°C, the measured trunk temperature is lower than 34°C and there is still a downward trend, it is abnormal, otherwise it is normal. If the ambient temperature exceeds 30°C, the measured heart rate exceeds 100 beats / minute and there is still an upward trend, it is abnormal, otherwise it is normal. If the ambient temperature is lower than 16°C, the measured blood pressure is higher than 135 / 85mmHg and there is still an upward trend, it is abnormal, otherwise it is normal. If the humidity exceeds 70%, and the measured body temperature exceeds 36°C, or the blood oxygen saturation is lower than 95%, it is abnormal, otherwise it is normal. If the oxygen concentration is lower than 19.5%, and the measured blood oxygen saturation is lower than 90%, or the heart rate exceeds 100 times / minute, it is abnormal, otherwise it is normal. If the CO2 concentration exceeds 1000ppm, and the measured blood pressure is higher than 140 / 90mmHg, it is abnormal, otherwise it is normal. If the PM2.5 concentration exceeds 75 7g / m3, and the measured blood oxygen saturation is lower than 95%, or the heart rate exceeds 100 times / minute, it is abnormal, otherwise it is normal.

[0077] In one embodiment of the present invention, for further explanation and limitation, the monitoring data is re-identified according to the operation duration joint sub-strategy to determine at least one joint identification result, including:

[0078] For each gas category with time correlation, if the gas concentration is greater than the corresponding first gas concentration threshold and the operation duration is greater than or equal to the first time threshold, the corresponding joint identification result is determined to be abnormal;

[0079] If the gas concentration is between the first gas concentration threshold and the second gas concentration threshold, and the operation duration is greater than the second time threshold, the corresponding joint identification result is determined to be abnormal.

[0080] In an embodiment of the present invention, for certain special types of gases, in the case of high concentration, the operator can only stay for a short time, and in the case of low concentration, the operator can stay for a certain time, but if the stay time exceeds a certain time, it will also pose a threat to the health of the operator. Therefore, for such time-related gases, secondary identification is performed according to the joint sub-strategy of the operation duration. Among them, the gas categories with time correlation include carbon monoxide, nitrogen dioxide, sulfur dioxide, nitrogen oxides and hydrogen sulfide. The second time threshold is greater than the first time threshold, and the first gas concentration threshold is greater than the second gas concentration threshold. The first gas concentration threshold of carbon monoxide can be configured as 40mg / m3 (about 34ppm), and the second gas concentration threshold can be configured as 20mg / m3 (about 17ppm). The first gas concentration threshold of nitrogen dioxide can be configured as 10mg / m3, and the second gas concentration threshold can be configured as 5mg / m3. The first gas concentration threshold of sulfur dioxide can be configured as 20mg / m3, and the second gas concentration threshold can be configured as 10mg / m3. The second gas concentration threshold of nitrogen oxides can be configured as 30mg / m3. The first gas concentration threshold of hydrogen sulfide can be configured as 15 mg / m3, and the second gas concentration threshold can be configured as 10 mg / m3. The first time threshold can be configured as 15 minutes, and the second time threshold can be configured as 8 hours. The operation duration can be obtained by counting the time when the operator enters the chamber, or by counting wearable monitoring equipment (the operation time needs to be reset when the operator wears it on the job). The above-mentioned second time threshold, first time threshold, first gas concentration threshold, and second gas concentration threshold can be set based on the above-mentioned parameters, or they can be customized according to actual application requirements, and the embodiments of the present invention do not make specific limitations.

[0081] In an embodiment of the present invention, for further explanation and limitation, the method further includes:

[0082] Obtaining historical monitoring data and historical location information of the wearable monitoring device within a preset time interval;

[0083] generating a displacement-gas concentration curve of at least one key gas category based on the historical monitoring data and the historical location point information;

[0084] Fitting the displacement-gas concentration curve to obtain a predicted value of gas concentration at an expected operation location;

[0085] If the predicted gas concentration value is greater than the third gas concentration threshold, an early warning message is generated to prompt the operator to stop the forward movement operation.

[0086] In the embodiment of the present invention, the critical gas is a gas that poses a great threat to the operator and needs to be closely watched, such as flammable and explosive gas, oxygen, carbon monoxide, hydrogen sulfide gas, etc. According to the historical position point information, the displacement distance, displacement direction and other information of the operator are determined. According to the change of gas concentration with the information of different position points, a displacement-gas concentration curve can be constructed to describe the linear relationship between gas concentration and displacement change. For example, a curve is generated with displacement as the horizontal coordinate and gas concentration as the vertical coordinate. This curve is fitted to predict the gas concentration corresponding to the next displacement value, that is, the predicted value of the gas concentration at the expected operation position. If the predicted value of the gas concentration is greater than the third gas concentration threshold, indicating that the environment in the direction of the operation is dangerous, a warning message is generated to prompt the operator to stop moving forward. Among them, the third gas concentration threshold is the concentration limit value of the corresponding gas category, which can be configured according to the different targeted configurations of different gas categories, and the embodiment of the present invention does not make specific restrictions. Among them, the fitting process can be implemented by a logistic regression algorithm, or it can be implemented by a discount coefficient method, and the embodiment of the present invention does not make specific restrictions.

[0087] In one embodiment of the present invention, for further explanation and limitation, determining the location point information corresponding to the wearable monitoring device according to the electromagnetic wave signal transmission data includes:

[0088] For any of the wearable monitoring devices, obtaining electromagnetic wave signal transmission data of the three nearest wireless access points;

[0089] Calculate the distance between each of the wireless access points and the wearable monitoring device respectively, and determine three spherical ranges with each of the wireless access points as the center and the corresponding distance as the radius;

[0090] The intersection point of the three spherical ranges is determined as the position point of the wearable monitoring device, and the position information of this position point is determined as the position point information of the wearable monitoring device.

[0091] In the embodiment of the present invention, an electromagnetic wave positioning module is integrated in the wearable monitoring device. The wireless access point can emit electromagnetic waves. After the signal reaches the positioning device carried by the construction personnel, it returns to the wireless access point. Therefore, the distance between the construction personnel and the wireless access point can be determined according to the time after the electromagnetic wave is refracted back. The electromagnetic wave signal transmission data includes the time t from the electromagnetic wave being emitted to the return. Assuming the distance between the wireless access point and the construction personnel is x, the distance calculation formula can be expressed as:

[0092]

[0093] Where c is the speed of light. After measuring the distance between the construction workers and the three wireless access points. Figure 3As shown, a sphere is drawn with the wireless access point as the center and the distance as the radius. The intersection of the three spheres is the location of the operator.

[0094] It should be noted that a plurality of wireless signal access points are arranged in the target chamber, and the top-view plane distribution of the wireless access points in the chamber can be as follows: Figure 4 In the manner shown, in the three-dimensional space dimension, three adjacent wireless signal access points are distributed in different spatial planes, that is, three adjacent wireless signal access points cannot be arranged in the same plane.

[0095] In one embodiment of the present invention, for further explanation and limitation, generating the global construction environment monitoring result of the target chamber based on the location point information, the single-point construction environment monitoring result and the monitoring data includes:

[0096] Associating the single-point construction environment monitoring result with the location point information;

[0097] According to the location point information, the single-point construction environment monitoring result is marked to the corresponding point in the pre-constructed three-dimensional space model of the target chamber, and the global construction environment monitoring result of the target chamber is generated;

[0098] The method further includes: sending the global construction environment monitoring result of the target chamber to a display terminal to display the global construction environment monitoring result.

[0099] In the embodiment of the present invention, in order to display the monitoring results more intuitively, a three-dimensional spatial model of the target chamber is pre-constructed. After the location point information is determined, the location point is marked in the three-dimensional spatial model of the target chamber, and the single-point construction environment monitoring results and monitoring data of this location point are marked and displayed at the location point, so that the monitoring personnel can intuitively understand the position distribution of the operating personnel in the chamber and the environmental conditions of different location points through the display terminal, and timely deploy the operating personnel in the chamber according to the environmental monitoring results to ensure the safety of the operating personnel.

[0100] The present invention provides a method for monitoring the construction environment of a cavern. The embodiment of the present invention obtains monitoring data of at least one wearable monitoring device and electromagnetic wave signal transmission data between the wireless access point and the wireless access point through a wireless access point arranged in the target cavern. The wearable monitoring device is carried one-to-one by the operator in the target cavern. The monitoring data includes environmental sampling data of the location point where the operator is located and vital sign sampling data of the operator; the location point information corresponding to the wearable monitoring device is determined according to the electromagnetic wave signal transmission data; the single-point construction environment monitoring results of different location points are determined according to the monitoring data; the global construction environment monitoring results of the target cavern are generated according to the location point information, the single-point construction environment monitoring results and the monitoring data. The distance between the monitoring device and the operator is greatly shortened, the flexibility of the monitoring position is improved, and the accuracy of the monitoring positioning is improved. At the same time, the vital sign sampling data and the environmental sampling data of the comprehensive operator are used together as the basis for determining the environmental monitoring results, which greatly improves the accuracy of environmental monitoring and the dimension of monitoring, and greatly improves the accuracy of cavern construction environment monitoring, thereby meeting the needs of comprehensive protection of the safety of the operator.
