Description

Technical Field

[0001] The invention belongs to the technical field of power operation safety monitoring, and in particular relates to a safety alarm system and method for power construction workers using a safety helmet. Background Art

[0002] In the process of power construction, ensuring production safety and the safety and health of on-site workers has become an important task faced by power grid workers. The power construction environment is complex and changeable, and there are potential safety risks in high-altitude operations, electrical equipment operation, and heavy object handling. Therefore, taking effective safety measures to reduce accidents is the key to ensuring the smooth progress of construction. Safety helmets are one of the essential personal protective equipment in power construction. They are used to protect the heads of workers from being hit by falling objects or injuries caused by collisions. During power construction operations, it is often necessary to work at high altitudes or in an environment with the risk of falling objects. Safety helmets can effectively reduce the impact force and head injuries when the heads of workers are hit or collided by falling objects, and even save lives in some cases. The safety helmets currently used on the market have a single function and mainly provide basic physical protection. During power construction, once a safety accident occurs to the workers, such as electric shock, falling from height, etc., the workers can only seek help on their own. If the accident is serious, the workers are in a coma, or injured and unable to move on their own, this will greatly increase the difficulty and time of rescue, and cause the workers to miss the best time for treatment. Therefore, a safety alarm system for electric power construction workers wearing safety helmets is needed to warn workers of dangers such as not wearing safety helmets, head collisions, and proximity to electricity during the electric power construction process, so as to protect the safety of workers.

[0003] Disadvantages of the existing technology: the existing safety helmets have single functions, some of which have the functions of hat removal alarm or collision alarm, and there is no safety helmet alarm system that integrates hat removal alarm, collision alarm and high-voltage alarm. Summary of the invention

[0010] Furthermore, it also includes a video call module, which is connected to the main control module for two-way communication. The video call module is used to take photos of the work site, record videos of the work site, and send the photos and video data to the main control module; it is used for backstage managers to make video calls. Furthermore, it also includes a data storage module, which is bidirectionally connected to the main control module for storing alarm data and audio and video data of the work site. The safety alarm method for electric power construction workers based on the above safety alarm system is characterized by comprising: S1, real-time measurement of the distance between the helmet and the head, the high-voltage signal, the angular velocity of the helmet, the acceleration of the helmet, and the direction and intensity of the magnetic field of the helmet on three mutually perpendicular axes, and sending the distance between the helmet and the head, the high-voltage signal, the angular velocity of the helmet, the acceleration of the helmet, and the direction and intensity of the magnetic field of the helmet on three mutually perpendicular axes to the main control module; S2, the main control module compares the distance value, the high-voltage signal, the angular velocity of the helmet, the acceleration of the helmet and the set threshold value, and when the data collected by the sensor exceeds the alarm threshold, sends an alarm message to the alarm module, and sends the alarm message to the data management platform; determines the motion state of the helmet according to the direction and strength of the magnetic field of the helmet on three mutually perpendicular axes; when the motion state of the helmet is abnormal, sends an alarm message to the alarm module, and sends the alarm message to the data management platform; The alarm module receives the alarm information sent by the main control module in real time and sends out an alarm signal.

[0011] Furthermore, it also includes: workers wearing safety helmets turn on the camera to take photos and record videos of the work site, the main control module saves the photos in the storage module, and clicking the call button can make a video call with the backend management personnel through the main control module and the 4G communication module.

[0021] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be another element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon at the same time. The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. used herein indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] Example 1 Reference Figure 1 A safety alarm system for electric power construction workers with hard hats includes a hard hat, a sensor module, a main control module, an alarm module, a video call module, a data storage module, a 4G communication module, a power module and a data management platform. The sensor module includes a distance sensor, a 9-axis gyroscope sensor and a high-voltage electric sensor.

[0024] The output end of the sensor module is connected to the input end of the main control module, the video call module, the digital storage module, and the 4G communication module are all connected to the main control module for two-way communication, the input end of the alarm module is connected to the output end of the main control module, and the 4G communication module is connected to the data management platform for two-way communication.

[0025] Safety helmet: consists of a helmet shell, a hat lining and a chin strap.

[0026] Sensor module: Built into the helmet, including distance sensor, 9-axis gyroscope sensor and high-voltage electrical sensor.

[0027] Distance sensor, the working principle of the distance sensor is to calculate the distance based on the time difference between the emission and reception of infrared rays. Specifically, the distance sensor emits a short light pulse and measures the time from the emission to the reflection of the light pulse by the object. By calculating this time difference, the distance between the sensor and the object can be calculated. In the hat-off alarm, when the distance between the helmet and the head exceeds the set threshold, the system determines that the operator is not wearing a helmet, thus triggering an alarm.

[0028] The nine-axis gyroscope sensor uses the MPU-9250 multi-chip module, which contains a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer. The gyroscope measures the angular velocity of the helmet, the accelerometer measures the acceleration of the helmet, and the 3-axis magnetometer measures the direction and strength of the earth's magnetic field. The motion state of the helmet is indirectly reflected by measuring the magnetic field components of the helmet on three mutually perpendicular axes. The gyroscope sensor uses sensors such as gyroscopes and accelerometers to detect the acceleration and angular velocity generated during the motion of the helmet. By measuring the changes in the angular velocity and acceleration of the helmet before and after the impact, the occurrence and direction of the impact can be determined. Specifically, before the impact occurs, the gyroscope measures the angular velocity of the helmet, and the accelerometer measures the acceleration of the helmet. After the impact occurs, the gyroscope and accelerometer continue to measure the angular velocity and acceleration of the helmet. By comparing the changes in angular velocity and acceleration before and after the impact, it can be determined whether the impact occurred and the direction of the impact. When a helmet collides, the collision force will cause acceleration and angular velocity on the helmet. The gyroscope sensor measures the instantaneous changes in acceleration and angular velocity, and determines whether to issue a collision alarm signal based on the acceleration and angular velocity thresholds set by the system, thereby triggering an alarm.

[0029] High-voltage electric sensor: Using the CYG508 module, the working principle is based on the electromagnetic induction phenomenon. When the high-voltage signal passes through the sensor, it will cause the current in the coil inside the sensor to change. According to Faraday's law of electromagnetic induction, the current change will produce a corresponding change in the electromagnetic field, thereby generating a voltage signal at the output end of the sensor; the main control module converts the voltage signal into a low-voltage signal and amplifies it. After conversion and amplification, the main control module sets the alarm threshold for the processed voltage signal according to different levels of high-voltage safety distances. When the on-site workers approach different levels of high-voltage safety distances (as shown in Table 1), the alarm is triggered and the system sends a high-voltage alarm signal to remind the on-site workers to pay attention to the danger of high-voltage electricity.

[0031] Table 1 Main control module: Built into the helmet, it cleans the raw data collected by the distance sensor, 9-axis gyroscope sensor, and high-voltage electric sensor to remove abnormal values, error values, and redundant data. The system sets an alarm threshold. When the data collected by the sensor exceeds the alarm threshold, the main control module sends an alarm signal to the alarm module and sends the alarm information to the data management platform through the 4G communication module.

[0032] Alarm module: built into the helmet, receives the alarm information sent by the main control module in real time and broadcasts the alarm voice.

[0033] Video call module: Use the HaaS700 module, which is built into the helmet and consists of a high-definition camera, speaker, microphone, etc. Turn on the camera to take photos and record videos of the work site, and click the call button to make a video call with the backstage manager.

[0034] Data storage module: Built into the helmet, it can store audio and video data and alarm information from the work site. The data storage module comes with a 16G memory card and can be expanded to a maximum of 256G.

[0035] 4G communication module: Built into the helmet, it provides high-speed and stable wireless data transmission function, transmitting alarm data, audio and video data from the main control module to the data management platform.

[0036] Power module: Use HKYC polymer lithium battery, built into the helmet, to provide 3.8v power support for the helmet.

[0037] The data management platform uses a converged communication dispatching and command system. This system includes a converged communication module, a video conferencing module, a cluster intercom module, a data storage module, etc., and has image, video data, alarm data, and historical information query functions.

The main control module determines whether the operator is wearing a safety helmet according to the distance value and the set distance threshold. If the judgment result is that the operator is not wearing a safety helmet, an alarm message of "not wearing a safety helmet" is sent to the alarm module, and the alarm message is sent to the data management platform through the 4G communication module; the alarm module broadcasts the alarm voice of "not wearing a safety helmet"; The main control module determines whether the operator has collided with the helmet according to the angular velocity and acceleration of the helmet and the set angular velocity and acceleration thresholds. If the judgment result is that a collision has occurred, the main control module sends an alarm message of "collision" to the alarm module, and sends the alarm message to the data management platform through the 4G communication module; the alarm module broadcasts the alarm voice of "collision"; The main control module determines whether there is a high-voltage electricity hazard based on the received voltage signal and the threshold values ​​set for different levels of high-voltage safety distances. If the determination result is that there is a high-voltage electricity hazard, an alarm message of "high-voltage electricity hazard" is sent to the alarm module, and the alarm message is sent to the data management platform through the 4G communication module; the alarm module broadcasts the "high-voltage electricity hazard" alarm voice.
