Each underground worker is equipped with a portable underground device and a ground rescue center is established. The worker's vital sign data detected by each underground device is compared with standard vital sign data. When the vital sign data is abnormal, the underground device sends an abnormal signal and its location to the ground rescue center. The ground rescue center obtains the underground devices around it based on the location and sends the location of the underground device corresponding to the abnormal information to the obtained underground device. When the location of the underground device corresponding to the abnormal information is received, the surrounding underground devices create a navigation to the location and execute it. The present invention fully guarantees the life safety of the underground workers by promptly notifying the surrounding colleagues when the worker's vital sign data is abnormal, so that the worker can be quickly given first aid.

Description

Technical Field

[0001] The present invention relates to the field of underground detection, and in particular to a method for processing real-time vital sign alarms of coal mine workers underground. Background Art

[0002] As an important national energy source, coal mining is indispensable to my country's production and life. Therefore, coal mining is also an essential project. However, coal mining is a very difficult job. When mining goes wrong, it will seriously endanger the lives of workers. Therefore, it is very important to detect the vital signs of workers underground and implement timely rescue in the process of coal mining.

[0003] When working underground, workers are equipped with special electronic monitoring equipment. This electronic monitoring equipment can not only monitor the physical signs of underground workers, but also monitor their location. At the same time, it can provide communication between underground workers and the ground, thereby ensuring the safety of underground workers from multiple aspects.

[0004] Although such equipment can monitor the location of underground workers and contact them through communication when their physical signs are abnormal, it can also implement rescue. However, for those with abnormal physical signs, getting them treated as soon as possible is a top priority. Therefore, how to provide timely assistance to underground workers when their physical signs are abnormal is an important research topic. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art and provide a method for processing real-time vital sign alarms of coal mine workers underground. When the physical sign data of the workers are abnormal, the colleagues around them are promptly notified and first aid is quickly provided to them, thereby fully ensuring the life safety of the workers underground.

[0006] To this end, the present invention provides a method for processing real-time vital sign alarms of coal mine workers underground, comprising the following steps:

[0007] Each underground worker is equipped with a portable underground device, and the underground device is matched with the worker one by one. At the same time, a ground rescue center is established so that each underground device is connected to the ground rescue center signal;

[0008] Comparing the physical sign data of the worker detected by the downhole equipment with the standard physical sign data, and when the physical sign data is abnormal, the downhole equipment sends an abnormal signal and its location to a ground rescue center;

[0009] The ground rescue center obtains the location of the downhole equipment corresponding to the abnormal signal through the center-of-circle diffusion method, and sends the location of the downhole equipment corresponding to the abnormal signal to the obtained downhole equipment;

[0010] When the surrounding downhole equipment receives the location of the downhole equipment corresponding to the abnormal information, it creates and executes navigation to the location.

[0011] Furthermore, the center diffusion method includes the following steps:

[0012] Taking the position of the downhole equipment corresponding to the abnormal information as the center of the circle and the set initial distance as the radius, an initial range is obtained;

[0013] detecting whether there is other downhole equipment in the initial range, and outputting the detected downhole equipment as the surrounding downhole equipment;

[0014] When no other downhole equipment corresponding to a position is detected in the initial range, the distance between the downhole equipment corresponding to the abnormal information and the ground rescue center is calculated as the final distance;

[0015] The final range is obtained by taking the position of the downhole equipment corresponding to the abnormal information as the center of the circle and the final distance as the radius;

[0016] Sequentially expanding the initial range to obtain a transition range until the transition range is consistent with the final range, detecting whether there is a position corresponding to other downhole equipment in the transition range, and outputting the detected downhole equipment as the surrounding downhole equipment;

[0017] When no other underground equipment is detected in the final range, the ground rescue center issues an alarm and sends the location of the underground equipment corresponding to the abnormal information to the terminal of the rescuer.

[0018] Furthermore, when the initial range is sequentially expanded to obtain the transition range, the following steps are included:

[0019] Obtaining a value range of the radius according to the initial distance and the final distance;

[0020] Divide the radius value range into multiple sub-ranges of equal length from large to small;

[0021] Obtaining a value in each of the sub-ranges as the value of the radius;

[0022] Output the transition range corresponding to each radius value.

[0023] Furthermore, the value range of the radius is divided into three sub-ranges of equal length from large to small.

[0024] Furthermore, when obtaining a value in each of the sub-ranges as the value of the radius, the value is taken as the median of the sub-range.

[0025] Furthermore, when the ground rescue center obtains the surrounding downhole equipment based on the location of the downhole equipment corresponding to the abnormal signal, the ground rescue center issues an alarm and sends the location of the downhole equipment corresponding to the abnormal information to the rescuer's terminal.

[0026] Furthermore, the underground equipment is an underground watch, which obtains the physical data of the underground workers by detecting their heart rate data.

[0027] Furthermore, when the surrounding downhole equipment receives the location of the downhole equipment corresponding to the abnormal information, it creates and executes navigation to the location and issues an alarm at the same time.

[0028] The present invention provides a method for processing real-time vital sign alarms of coal mine workers underground, which has the following beneficial effects:

[0029] After the worker's vital sign data is confirmed to be abnormal, the system will obtain the worker's current real-time location and area underground by connecting with the underground personnel positioning system, automatically find other workers working in the same area with the worker, and automatically push the worker's location, alarm type and other information to other workers in the same area. The push results are fed back to the system administrator, so that colleagues around the worker with abnormal vital sign data underground can provide him with timely and rapid treatment, and at the same time, the system administrator is prompted to provide professional treatment to the worker with abnormal vital sign data on the ground in a timely manner.

[0030] When there are no other employees in the area around the employee with abnormal vital sign data, the system of the present invention will automatically expand the search range to the adjacent area. If no other employees are found after expanding the search range three times, the system will feedback the information that no surrounding employees can be found to the system administrator. The system administrator will arrange for ground personnel to go down the well to deal with the situation. By expanding the help-seeking area, the scope of rapid search and rescue for employees is increased, so that the life safety of employees is fully guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A specific embodiment of the present invention is described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0035] In this application document, the component models and structures that are not clearly defined are all existing technologies known to those skilled in the art. Those skilled in the art can set them according to the actual needs and are not specifically limited in the embodiments of this application document.

[0036] Specifically, such as Figure 1-3 As shown, an embodiment of the present invention provides a method for processing real-time vital sign alarms of coal mine workers underground, comprising the following steps:

[0037] (1) Each underground worker shall be equipped with a portable underground device, and the underground device shall be matched with the worker on a one-to-one basis. At the same time, a ground rescue center shall be established so that each underground device can be connected to the ground rescue center by signal;

[0038] (2) comparing the physical sign data of the employee detected by the downhole equipment with standard physical sign data; when the physical sign data is abnormal, the downhole equipment sends an abnormal signal and the location of the abnormal signal to a ground rescue center;

[0039] (3) The ground rescue center obtains the location of the downhole equipment corresponding to the abnormal signal by means of a circle-centered diffusion method, and sends the location of the downhole equipment corresponding to the abnormal signal to the obtained downhole equipment;

[0040] (4) When the surrounding downhole equipment receives the location of the downhole equipment corresponding to the abnormal information, it creates and executes navigation to the location.

[0041] In the above technical solution, steps (1) to (4) are performed in a logical order. By real-time monitoring of the vital data of each underground personnel, when the vital data of the underground employee is abnormal, the nearby employees are promptly notified to rescue him, thereby greatly improving the efficiency of the rescue. At the same time, the employees with abnormal vital data have a greater sense of security when they encounter difficulties, which is conducive to the employees with abnormal vital data to maintain a good state and be easy to rescue in the subsequent rescue. At the same time, the navigation technology is used to provide the surrounding employees so that they can reach the employee with abnormal vital data as soon as possible, carry out basic rescue, and increase the success rate of their subsequent rescue. In addition, the present invention can gradually expand the search range for other employees by diffusion from the center of the circle, so that the employees closest to the employee with abnormal vital data can first reach the employee with abnormal vital data and complete the initial rescue.

[0042] At the same time, the present invention places all monitoring and rescue work at the ground rescue center, so that the underground equipment carried by underground workers only has a single communication and detection function. This can not only effectively reduce energy consumption, but also effectively prevent random communication between underground workers, thereby improving the work efficiency of underground workers and allowing the ground rescue center to fully understand the working status of underground workers. At the same time, by defining the scope of rescue through the ground rescue center, it can also effectively solve the problem of poor communication between various underground equipment in the well.

[0043] Regarding the center diffusion technology used in the present invention, in the present invention, the center diffusion method includes the following steps:

[0044] (1) Taking the position of the downhole equipment corresponding to the abnormal information as the center of the circle and the set initial distance as the radius, an initial range is obtained;

[0045] (2) detecting whether there are other downhole devices in the initial range whose positions correspond to each other, and outputting the detected downhole devices as the surrounding downhole devices;

[0046] (3) When no other downhole equipment corresponding to a position in the initial range is detected, the distance between the downhole equipment corresponding to the abnormal information and the ground rescue center is calculated as the final distance;

[0047] (4) Taking the position of the downhole equipment corresponding to the abnormal information as the center of the circle and the final distance as the radius, the final range is obtained;

[0048] (5) sequentially expanding the initial range to obtain a transition range until the transition range is consistent with the final range, detecting whether there is a location corresponding to other downhole equipment in the transition range, and outputting the detected downhole equipment as the surrounding downhole equipment;

[0049] (6) When no other underground equipment is detected in the final range, the ground rescue center issues an alarm and sends the location of the underground equipment corresponding to the abnormal information to the rescuer's terminal.

[0050] In the above technical solution, steps (1) to (6) are performed in a logical order. By searching for other underground equipment in the initial range, other underground workers can be found, so that the underground workers can quickly reach the distressed employees. When no underground workers are found in this initial range, the fastest rescue is determined by setting the final range. When there is no underground equipment in the final range, the rescue by the ground rescue center is the fastest. When there is rescue in the final range, the nearby underground workers are first allowed to reach the distressed employees while waiting for the rescue by the ground rescue center, so that the life safety of the employees is fully guaranteed.

[0051] In addition, when the initial distance is greater than the final distance, rescue will be provided directly by the ground rescue center.

[0052] Preferably, when the initial range is sequentially expanded to obtain the transition range, the following steps are included:

[0053] <1> obtaining a value range of the radius according to the initial distance and the final distance;

[0054] <2> dividing the radius value range into a plurality of sub-ranges of equal length in descending order;

[0055] <3> obtaining a value in each of the sub-ranges as the value of the radius;

[0056] <4> Output the transition range corresponding to each radius value.

[0057] In the above technical solution, steps <1> to <4> are performed in a logical order. In the present invention, each transition range forms a concentric circle relationship with the initial range and the final range, so that the nearest employee can be gradually found by gradually expanding.

[0058] Preferably, the present invention has learned through repeated practice that the radius range is divided into three sub-ranges of equal length from largest to smallest. At the same time, when obtaining a value in each sub-range as the radius value, the present invention uses the median value of the sub-range. This allows for rapid identification of the nearest employee, allowing support to quickly arrive at the distressed employee's side.

[0059] In the present invention, when the ground rescue center obtains the location of the underground equipment surrounding the employee based on the location of the underground equipment corresponding to the abnormal signal, the ground rescue center issues an alarm and sends the location of the underground equipment corresponding to the abnormal information to the rescuer's terminal. The present invention automatically pushes the employee's location, alarm category, and other information to other employees in the same area, and feeds the push results back to the system administrator, so that colleagues around the employee with abnormal vital sign data in the underground can provide timely and expedited medical treatment to the employee, while also prompting the system administrator to provide timely and professional medical treatment to the employee with abnormal vital sign data on the ground.

[0060] At the same time, in the present invention, in order to enable underground workers to receive signals from the surface in a timely manner, the underground equipment is configured as an underground watch, and the worker's vital sign data is obtained by detecting the worker's heart rate data. Since the watch can be partially worn on the hand, it will not interfere with the work when working underground. Therefore, configuring the underground equipment as an underground watch is conducive to accurately locating the worker's position, and the position of the equipment and the person will not be separated, which is beneficial to the accurate rescue work of the underground workers in times of crisis.

[0061] In the present invention, upon receiving the location of the underground equipment corresponding to the abnormality information, the surrounding underground equipment creates and executes navigation to that location, while also issuing an alarm. This allows colleagues nearby the worker with abnormal vital sign data to provide prompt and expedited medical treatment. By issuing an alarm to alert working workers, navigation can quickly reach the distressed worker, improving rescue efficiency.

[0062] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
