TECHNICAL FIELD

[0001] The present application relates to the technical field of substation safety management and control, and particularly relates to a safety management and control system. BACKGROUND

[0002] The electric power industry is a high-risk industry, and in the process of construction, operation and maintenance, routine testing, there are many risks such as live work, near-live work, and high-altitude work. If the workers are careless, personal injury accidents will occur. Safety production is the basis for the development of the electric power industry, and the safety protection work of the construction site has always been the focus of work.

[0003] However, there are still non-workers entering the substation at present. In the actual construction process, some workers often lack safety awareness and do not wear safety helmets.

[0004] Therefore, there is an urgent need for a safety management and control system that can identify the identity of the personnel to be entered and detect the wearing of safety helmets. SUMMARY

[0005] The purpose of the present application is to provide a safety management and control system that can identify the identity of the personnel to be entered and detect the wearing of safety helmets, so as to ensure that the personnel entering the substation are workers and the workers wear safety helmets, and to ensure the safety of the construction site.

[0006] To achieve the above purpose, the present application provides the following scheme:

[0007] A safety management and control system, the safety management and control system comprises a management station, a safety management and control device arranged on a safety helmet, and an image acquisition device arranged at an entrance of a substation construction site; the safety management and control device and the image acquisition device are in communication connection with the management station;

[0008] The safety management and control device is used for emitting infrared rays into the safety helmet to obtain infrared reflection data, and collecting acceleration data and pressure data received by the safety helmet; the management station is used for comprehensively judging whether the safety helmet is worn by the personnel to be entered according to the infrared reflection data, the acceleration data and the pressure data;

[0009] The image acquisition device is used for collecting face information of the personnel to be entered wearing the safety helmet; the management station is used for comparing the face information with face information of workers pre-stored in the management station to judge whether the personnel to be entered wearing the safety helmet are workers; when the personnel to be entered wearing the safety helmet are workers, the personnel to be entered wearing the safety helmet are allowed to enter the substation construction site.

[0010] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0011] This invention provides a safety control system, including a management station, a safety control device mounted on a safety helmet, and an image acquisition device installed at the entrance of a substation construction site. Both the safety control device and the image acquisition device are communicatively connected to the management station. The safety control device emits infrared light into the safety helmet to obtain infrared reflection data and collects acceleration and pressure data experienced by the helmet. The management station uses the combined infrared reflection, acceleration, and pressure data to determine whether the safety helmet is being worn by a person entering the substation. The image acquisition device collects facial information of the person wearing the safety helmet. The management station compares this facial information with pre-stored facial information of other workers to determine if the person wearing the safety helmet is indeed a worker. If the person wearing the safety helmet is a worker, they are allowed to enter the substation construction site. Thus, the safety control system provided by this invention can identify the person entering the substation and detect whether they are wearing a safety helmet, ensuring that all personnel entering the substation are workers and are wearing safety helmets. In other words, only workers wearing safety helmets are allowed to enter the substation construction site, ensuring the safety of the construction site. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The purpose of this invention is to provide a safety management system that can identify personnel entering the substation and detect whether they are wearing safety helmets, ensuring that all personnel entering the substation are workers and are wearing safety helmets, thus guaranteeing the safety of the construction site.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] This embodiment provides a security management system, such as Figure 1 As shown, the safety control system includes a management station 1, a safety control device 2 mounted on a safety helmet, and an image acquisition device 3 located at the entrance of the substation construction site. The safety control device 2 can be clipped onto or fixedly installed on the safety helmet. Both the safety control device 2 and the image acquisition device 3 are communicatively connected to the management station 1. The communication method can be wireless communication such as Bluetooth or Wi-Fi, or wired communication.

[0022] Currently, infrared sensors are generally used to detect whether a safety helmet is being worn. When a worker is wearing a safety helmet, their head blocks and reflects the infrared light emitted by the sensor, thus confirming that the helmet is on their head. However, when no safety helmet is being worn, any foreign object entering the helmet can block or reflect the infrared light, making this method of detecting helmet wear solely based on infrared sensors unreliable. Considering this issue, the safety control device 2 in this embodiment emits infrared light into the safety helmet to obtain infrared reflection data and collects acceleration and pressure data experienced by the helmet. The management station 1 uses the combined infrared reflection data, acceleration data, and pressure data to determine whether the helmet is being worn by the person entering the area. This multi-data-based approach improves the reliability of helmet wearing detection.

[0023] Management Station 1 determines whether a safety helmet is being worn by a person entering the area by combining infrared reflection data, acceleration data, and pressure data as follows: Infrared reflection data is used to determine whether infrared light is blocked or reflected; if it is, the helmet is being worn. Acceleration data is used to determine whether the helmet is being worn. Pressure data is used to determine whether the helmet is being worn. Only when all three data points indicate that the helmet is being worn, does Management Station 1 confirm that the helmet is being worn by the person entering the area.

[0024] Specifically, such as Figure 2 As shown, the safety control device 2 in this embodiment includes a housing 4 and an infrared sensor 5, an acceleration sensor 6, and a pressure sensor 7 disposed inside the housing 4. The infrared sensor 5, acceleration sensor 6, and pressure sensor 7 are all communicatively connected to the management station 1. The detection end of the infrared sensor 5 extends out of the housing 4. The infrared sensor 5 emits infrared light into the safety helmet to obtain infrared reflection data and transmits the infrared reflection data to the management station 1. The infrared sensor 5 can also be other sensors capable of emitting infrared light and obtaining infrared reflection data. The acceleration sensor 6 collects acceleration data received by the safety helmet and transmits the acceleration data to the management station 1. The acceleration sensor 6 can also be other sensors capable of collecting acceleration data. The pressure sensor 7 collects pressure data received by the safety helmet and transmits the pressure data to the management station 1. The pressure sensor 7 can also be other sensors capable of collecting pressure data.

[0025] Image acquisition device 3 is used to acquire facial information of personnel wearing safety helmets awaiting entry. Management station 1 includes a processor and a database, which pre-stores facial information corresponding to all workers. The processor of management station 1 compares the facial information of the personnel wearing safety helmets awaiting entry with the pre-stored facial information of workers in management station 1 to determine whether the personnel wearing safety helmets awaiting entry is a worker. If the similarity between the facial information of the personnel wearing safety helmets awaiting entry and the facial information of workers pre-stored in management station 1 is greater than a preset threshold, then the personnel wearing safety helmets awaiting entry is a worker. When the personnel wearing safety helmets awaiting entry are workers, they are allowed to enter the substation construction site.

[0026] The safety management system provided in this embodiment can identify the personnel entering the substation and detect whether they are wearing safety helmets, ensuring that all personnel entering the substation are workers and that they are wearing safety helmets. In other words, only workers wearing safety helmets are allowed to enter the substation construction site, thus ensuring the safety of the construction site.

[0027] As an optional implementation, the safety control system of this embodiment also includes an iris recognition sensor 8 installed at the entrance of the substation construction site, which is communicatively connected to the management station 1. The iris recognition sensor 8 is used to collect the iris data of personnel wearing safety helmets awaiting entry and transmit the iris data to the management station 1. The iris recognition sensor 8 can also be other sensors capable of collecting iris data. The database of the management station 1 pre-stores the iris data of all workers. The processor of the management station 1 compares the iris data of the personnel wearing safety helmets awaiting entry with the pre-stored iris data of workers in the management station 1 to determine whether the personnel wearing safety helmets awaiting entry is a worker. When the similarity between the iris data of the personnel wearing safety helmets awaiting entry and the pre-stored iris data of workers in the management station 1 is greater than a preset threshold, the personnel wearing safety helmets awaiting entry is considered a worker.

[0028] This embodiment can determine whether a person wearing a safety helmet is a worker based solely on the judgment result of the image acquisition device 3, or solely on the judgment result of the iris recognition sensor 8. Preferably, this embodiment can determine whether a person wearing a safety helmet is a worker based on both the judgment result of the image acquisition device 3 and the judgment result of the iris recognition sensor 8. Specifically, the person wearing a safety helmet is considered a worker only when both the image acquisition device 3 and the iris recognition sensor 8 determine that the person wearing a safety helmet is a worker, thereby improving the accuracy of the identification of the person entering the premises.

[0029] Substation construction sites often contain one or more energized hazardous areas. On-site workers may inadvertently approach these hazardous areas, potentially leading to personal injury accidents. To avoid this problem, the safety control system in this embodiment also includes microwave radar 9 and a voice recording and playback module 10 installed in the hazardous areas of the substation construction site. Each hazardous area is equipped with one microwave radar 9 and one voice recording and playback module 10, both of which are communicatively connected to the management station 1. The microwave radar 9 continuously emits microwave signals and receives the reflected signals from obstacles, transmitting the reflected signals to the management station 1. The management station 1 determines whether anyone has entered the sensing area of ​​the microwave radar 9 based on the reflected signals received by the microwave radar 9. When someone enters the sensing area of ​​the microwave radar 9, the management station activates the voice recording and playback module 10 to issue a hazard warning, specifically playing a voice reminder to remind workers to maintain a sufficient safe distance. The microwave radar 9 can achieve 360-degree spherical coverage, and its sensing area covers the danger zone where it is located. This allows it to promptly detect workers entering the danger zone from any direction and immediately alert them via voice to maintain a safe distance, ensuring their personal safety.

[0030] To further prevent workers from entering hazardous areas and causing personal safety accidents, the safety control device 2 in this embodiment also includes a locator 11 and an alarm 12 installed inside the housing 4. Both the locator 11 and the alarm 12 are communicatively connected to the management station 1. The locator 11 can be a GPS module, a Beidou module, or other modules capable of collecting location data. The locator 11 is used to locate workers in real time, obtain their real-time location, and transmit the real-time location to the management station 1. The database of the management station 1 pre-stores the location data of all hazardous areas. The processor of the management station 1 compares the real-time location of the workers with the pre-stored hazardous area locations in the management station 1 to determine whether the workers are in hazardous areas. The alarm 12 is used to sound an alarm when workers are in hazardous areas to remind them to move to a safe location.

[0031] Substation operations are complex, and it's inevitable that workers will sometimes engage in non-standard operations. This not only affects the reliable operation of the substation but also threatens the safety of the workers themselves. To address this issue, the safety control device 2 in this embodiment also includes an audio / video acquisition unit 13 housed within the casing 4, which is communicatively connected to the management station 1. The audio / video acquisition unit 13 can be a camera, with its lens located outside the casing 4. The audio / video acquisition unit 13 is used to capture the workers' work behavior and transmit the captured data to the management station 1. The management station 1's database pre-stores standard operating data. The processor of the management station 1 compares the captured workers' work behavior with the pre-stored standard operating data to determine whether the workers are operating according to regulations. An alarm 12 is used to sound an alarm when workers are not operating according to regulations. Specifically, the method for comparing the operator's work behavior with the standard operation data is as follows: the processor converts the standard operation data into a series of action tags that the computer can recognize, and cuts the operator's work behavior to obtain segmented video data containing the operator's work behavior. Then, each segment of video data is matched with the action tags. When all segments of video data match the action tags successfully, it means that the operator is performing the work in accordance with the standard.

[0032] As an optional implementation, the safety control device 2 in this embodiment also includes a speaker 14 mounted on the housing 4, which is communicatively connected to the management station 1. The audio / video acquisition device 13 is also used to effectively capture the scene, obtaining on-site video, and transmitting the video to the management station 1. The management station 1 displays the on-site video for staff to view, allowing them to understand the situation in real time. When staff want to effectively control the scene based on the situation, they can issue control commands through the management station 1, which are then transmitted to the speaker 14. The speaker 14 plays the control commands, enabling workers to quickly understand them and respond to various emergencies. Alternatively, the safety control device 2 in this embodiment may also include a microphone 15 mounted on the housing 4, which is communicatively connected to the management station 1. The microphone 15 collects the audio of the workers, obtaining audio data, and transmits the audio data to the management station 1. After receiving the audio data, the staff at the management station 1 can provide real-time feedback and play the feedback through the speaker 14 to enable effective communication between on-site workers and staff at the management station 1, facilitating better work and response to various emergencies.

[0033] The safety control device 2 in this embodiment also includes an infrared temperature sensor 16 disposed within the housing 4, which is communicatively connected to the management station 1. The detection end of the infrared temperature sensor 16 is located outside the housing 4. The infrared temperature sensor 16 collects ambient temperature data and transmits the data to the management station 1. The management station 1's database pre-stores normal temperature threshold ranges. The processor of the management station 1 compares the ambient temperature data with these normal temperature threshold ranges. An alarm 12 is activated when the ambient temperature data is outside the normal temperature threshold range. By using the infrared temperature sensor 16 to detect the ambient temperature in real time, if the detected ambient temperature data is outside the normal temperature threshold range, it indicates a potential fire hazard, triggering an alarm 12 to allow personnel to quickly inspect surrounding equipment and eliminate the fire hazard.

[0034] Existing safety management processes do not involve collecting vital signs of workers, which may lead to the inability to promptly monitor workers' vital signs and thus fail to prevent construction safety issues. To address this problem, the safety management system in this embodiment also includes a wristband worn on the worker's arm, equipped with a heart rate sensor 17, which is communicatively connected to the management station 1. The heart rate sensor 17 collects the worker's heart rate parameters in real time and transmits them to the management station 1. The management station 1's database stores normal heart rate ranges. The processor in the management station 1 compares the worker's heart rate parameters with the pre-stored normal heart rate ranges in real time to determine if the worker's heart rate is normal. When the worker's heart rate parameters are within the normal heart rate range, the worker's heart rate is considered normal. An alarm 12 is used to sound an alarm when the worker's heart rate is abnormal, preventing workers with abnormal heart rates from remaining at the substation construction site and ensuring worker safety.

[0035] The safety control device 2 in this embodiment also includes an electric field strength detector 18 disposed inside the housing 4, which is communicatively connected to the management station 1. The electric field strength detector 18 is used to collect the electric field strength around the operator and transmit it to the management station 1. Specifically, the electric field strength detector 18 can be an electric field strength sensor or other sensor capable of detecting electric field strength. The electric field strength detector 18 achieves electric field strength detection by utilizing the strong electric field of the high-voltage line to generate an induced potential on the sensing electrode. The database of the management station 1 pre-stores normal intensity thresholds. The processor of the management station 1 compares the electric field strength with the pre-stored normal intensity thresholds to determine whether the operator is near an electric current source. When the electric field strength is greater than the normal intensity threshold, the operator is considered to be near an electric current source. The alarm 12 is used to sound an alarm when the operator is near an electric current source, thereby realizing a near-electric current alarm, reminding the operator to stay away from electrical facilities, and ensuring the personal safety of the operator.

[0036] The security control device 2 in this embodiment may further include a radio frequency antenna 19 and a communication module. All components in the security control device 2 that need to communicate with the management station 1 communicate with the management station 1 through the communication module and the radio frequency antenna 19. The radio frequency antenna 19 is used to assist the communication module in transmitting information when communication is required, which can effectively improve the information transmission rate. The communication module may be a 3G, 4G, 5G network module or a WIFI module.

[0037] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
