Technical Field
[0001] The present invention belongs to the technical field of high-altitude operation safety management, and specifically relates to a high-altitude operation personnel safety detection system. Background Art
[0002] High-altitude work refers to work activities performed at a high working height, which involves important issues of personal safety and health. Therefore, it is very necessary to conduct high-altitude work safety inspections. It can protect the lives of personnel and prevent the risk of falling: One of the biggest dangers in high-altitude work is the risk of falling. Therefore, in order to reduce the safety risks of high-altitude work, relevant safety regulations must be strictly followed when working at height, and necessary protective measures must be taken. The risks of high-altitude work can be minimized by regularly checking the status of equipment and tools, and paying attention to weather conditions.
[0003] With the acceleration of urbanization and the rapid development of the construction industry, aerial work has gradually become an important part of the construction process. The necessity of aerial work safety detection has prompted the continuous progress and improvement of related technologies and equipment. Aerial work safety detection is of great significance in protecting personnel life safety, improving work efficiency, enhancing corporate credibility, complying with regulatory requirements, responding to emergencies, and promoting technological progress. In order to improve the safety of aerial work, a method for aerial work safety detection is provided, and the present invention provides the following technical solutions. Summary of the invention
[0004] The purpose of the present invention is to provide a safety detection system for high-altitude workers, so as to solve the problem that the intelligence level of high-altitude work safety detection in the prior art is not high and it mainly relies on self-consciousness and supervision to achieve.
[0005] The purpose of the present invention can be achieved through the following technical solutions: A safety detection system for high-altitude workers, comprising: A radio frequency ranging unit, the radio frequency ranging unit comprising: A transponder installed at the end of the aerial work safety belt close to the human body; Reader 1 installed on the person working at height; Transponder 2 installed at the end of the aerial work safety belt away from the human body; Reader 1 sends out a wireless carrier signal, and obtains the distance x1 between reader 1 and transponder 1 and the distance x2 between reader 1 and transponder 2 according to the return signals from transponder 1 and transponder 2; High-definition camera unit, used to obtain image information of the high-altitude working area; An information processor is used to process the information uploaded by the high-definition camera unit and the radio frequency ranging unit, so as to determine whether the high-altitude workers are equipped with high-altitude work safety belts and whether the high-altitude work safety belts are properly equipped; An alarm unit is used to issue an alarm message.
[0006] As a further solution of the present invention, the safety detection method performed by the system is: The first step is to obtain the safety boundary of the high-altitude working area; The second step is to obtain image information of the high-altitude workers when they enter the high-altitude working area through the high-definition camera unit, and determine whether they are equipped with high-altitude working safety belts through the information processor; If the information processor determines that the corresponding high-altitude worker is not equipped with a high-altitude work safety belt, the alarm unit sends an alarm message, otherwise, the next step is performed; Step 3: For a high-altitude worker, when it is detected that the distance between the worker and the safety boundary is less than the preset value L, the reader 1 installed on the high-altitude worker starts working and obtains the distance x1 between the reader 1 and the transponder 1 and the distance x2 between the reader 1 and the transponder 2 according to the feedback signal of the transponder; When any of the following conditions are met, it is considered that the high-altitude work safety belt equipment of the high-altitude workers is abnormal: x1 is greater than the preset value x1y; x2 is greater than the preset value x2y, where x2y is the length of the connecting rope of the aerial work safety belt; When it is considered that the high-altitude work safety belt equipment of the high-altitude workers is abnormal, the alarm unit will issue an alarm message.
[0007] As a further solution of the present invention, the system further comprises: a radio frequency positioning module, comprising three or more readers 2 distributed in the high-altitude operation area; When working, several readers 2 send out wireless carrier signals and receive feedback information from transponders 1 in the high-altitude working area, so as to obtain the distance between transponder 1 and each reader 2, and then obtain the second spatial coordinates of each transponder 1.
[0008] As a further solution of the present invention, the method in which the information processor determines whether the aerial work personnel are equipped with the aerial work safety belt is as follows: S1. Establish a spatial coordinate system for the aerial work area. When the high-definition camera detects that there is an aerial worker in the aerial work area, obtain the first spatial coordinate of the aerial worker in the aerial work area at a preset time interval t2; S2, corresponding to the first spatial coordinates obtained in S1, obtaining a set of second spatial coordinates of each transponder in the aerial working area at every preset time t2; For the first spatial coordinates and a corresponding set of second spatial coordinates collected at the same time, the first spatial coordinates are marked as (x1, y1, z1), and one of the second spatial coordinates is marked as (x2, y2, z2). According to the formula A distance difference q is calculated; then the distance differences between the first spatial coordinate and each second spatial coordinate in the same group are calculated in sequence according to the method, and the smallest distance difference is selected as the actual distance difference qi at the corresponding moment; S3, according to the method in step S2, the actual distance differences qi corresponding to the consecutive n spatial coordinate collection moments are calculated in sequence; When the n actual distance differences qi all satisfy the condition of being less than or equal to the preset value qy, it is considered that the corresponding high-altitude workers are equipped with high-altitude work safety belts.
[0009] Furthermore, when k consecutive actual distance differences qi do not satisfy the condition of being less than or equal to the preset value qy, it is considered that the corresponding high-altitude worker is not equipped with a high-altitude work safety belt, and k is the preset value.
[0010] Beneficial effects of the present invention: 1. The present invention uses a method combining radio frequency ranging positioning and visual positioning to determine whether the aerial work personnel and the aerial work safety belt are in the same position, and then determines whether the aerial work personnel are equipped with the aerial work safety belt. Compared with the simple visual positioning method, the present invention can reduce the interference of the color and style of the staff's clothing and the color and style of the aerial work safety belt on the detection accuracy, improve the detection accuracy, and reduce false alarms.
[0011] 2. During the use of aerial work safety belts, there are cases where the workers fail to equip the aerial work safety belts according to regulations for the convenience of construction, resulting in the aerial work safety belts being unable to provide effective protection. Therefore, the present invention monitors the distances between several important nodes of the aerial work safety belts, thereby being able to discover this problem in a timely manner, prompting the workers and managers to take reasonable measures to ensure the safe and normal progress of the construction.

DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0015] A safety detection system for high-altitude workers, such as Figure 1 As shown, including: A radio frequency ranging unit, the radio frequency ranging unit comprising: A transponder installed at the end of the aerial work safety belt close to the human body; Reader 1 installed on the person working at height; Transponder 2 installed at the end of the aerial work safety belt away from the human body; When working, the wireless carrier signal is sent out by the reader 1 at a preset time interval t1. When the transponder enters the working area of the transmitting antenna of the reader 1, the transponder is activated and sends its own information code. According to the return signals of the transponder 1 and the transponder 2, the distance x1 between the reader 1 and the transponder 1 and the distance x2 between the reader 1 and the transponder 2 are obtained. The radio frequency positioning module includes a plurality of readers 2 distributed in the high-altitude operation area. Specifically, the number of readers 2 should be three or more; A high-definition camera unit, including a plurality of high-definition cameras, is used to obtain image information of the high-altitude working area and transmit the collected image information of the high-altitude working area to an information processor; An information processor is used to process the information uploaded by the high-definition camera unit, the radio frequency ranging unit and the radio frequency positioning module, so as to determine whether the high-altitude workers are equipped with high-altitude work safety belts and whether the high-altitude work safety belts are normal; The alarm unit is used to send out alarm information to remind the staff to deal with the behaviors that pose safety hazards such as improper equipment of high-altitude work safety belts in a timely manner.
[0016] like Figure 2 As shown, the method for performing safety detection by the safety detection system of the present invention comprises the following steps: The first step is to obtain the safety boundary of the high-altitude working area according to its location and surrounding environment. Specifically, the safety boundary refers to the high risk of falling when the high-altitude workers cross this boundary. The second step is to obtain image information of the high-altitude workers when they enter the high-altitude working area through the high-definition camera unit, and determine whether they are equipped with high-altitude working safety belts through the information processor; If the information processor determines that the corresponding high-altitude worker is not equipped with a high-altitude work safety belt, the alarm unit sends an alarm message to prompt the corresponding staff to take corresponding measures. On the contrary, if the information processor determines that the corresponding high-altitude worker is equipped with a high-altitude work safety belt, the next step is performed; Since the colors of high-altitude work safety belts are diverse and the clothing of high-altitude workers is also diverse, the accuracy of simply analyzing whether high-altitude workers are wearing high-altitude work safety belts through images is poor. In order to improve the accuracy of the analysis, this embodiment provides a specific method for determining whether the worker is wearing a high-altitude work safety belt, which includes: S1. Establish a spatial coordinate system for the aerial work area. When the high-definition camera detects that there are aerial workers in the aerial work area, the spatial coordinates of the aerial workers in the aerial work area are obtained at preset intervals of t2. For the convenience of description, the coordinates are referred to as first spatial coordinates. Specifically, binocular positioning and other methods may be used. S2, the radio frequency positioning module starts working, a number of readers 2 send out wireless carrier signals, and receive feedback information from the transponder 1 in the high-altitude working area, so as to obtain a set of spatial coordinates of each transponder 1 in the high-altitude working area at a preset time t2 corresponding to the first spatial coordinates obtained in step S1. For the convenience of expression, the coordinates are called second spatial coordinates; For the first spatial coordinates and a corresponding set of second spatial coordinates collected at the same time, the first spatial coordinates are marked as (x1, y1, z1), and one of the second spatial coordinates is marked as (x2, y2, z2). According to the formula A distance difference q is calculated; then the distance differences between the first spatial coordinate and each second spatial coordinate in the same group are calculated in sequence according to the method, and the smallest distance difference is selected as the actual distance difference qi at the corresponding moment; S3, according to the method in step S2, the actual distance difference qi corresponding to the consecutive n spatial coordinate collection moments is calculated in sequence, When the n actual distance differences qi all meet the condition that they are less than or equal to the preset value qy, it is considered that the corresponding high-altitude workers are equipped with high-altitude work safety belts; On the contrary, when the k consecutive actual distance differences qi do not satisfy the condition of being less than or equal to the preset value qy, it is considered that the corresponding high-altitude operation personnel are not equipped with a high-altitude operation safety belt, where k is a preset value.
[0017] This step uses a combination of radio frequency ranging positioning and visual positioning to determine whether the aerial work personnel and the aerial work safety belt are in the same position, and then determines whether the aerial work personnel are equipped with aerial work safety belts. Compared with the simple visual positioning method, the present invention can reduce the interference of the color and style of the personnel's clothing and the color and style of the aerial work safety belt on the detection accuracy, improve the detection accuracy, and reduce false alarms.
[0018] Step 3: For a high-altitude worker, when it is detected that the distance between the worker and the safety boundary is less than the preset value L, the reader 1 installed on the high-altitude worker starts working and obtains the distance x1 between the reader 1 and the transponder 1 and the distance x2 between the reader 1 and the transponder 2 according to the feedback signal of the transponder; When any of the following conditions are met, it is considered that the high-altitude work safety belt equipment of the high-altitude workers is abnormal: x1 is greater than the preset value x1y; x2 is greater than a preset value x2y, where x2y is the length of the aerial work safety belt connecting rope (the rope between the two hooks connecting the fixed point and the human body).
[0019] When it is considered that the high-altitude work safety belt equipment of the high-altitude workers is abnormal, the alarm unit will issue an alarm message to prompt the relevant staff to take corresponding measures.
[0020] During the use of aerial work safety belts, there are cases where the workers fail to equip the aerial work safety belts according to regulations for the convenience of construction, resulting in the aerial work safety belts being unable to provide effective protection. The present invention monitors the distances between several important nodes of the aerial work safety belts, thereby being able to discover this problem in a timely manner, prompting the workers and managers to take reasonable measures, and ensuring the safe and normal progress of the construction.
[0021] The above contents are merely examples and explanations of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the invention or exceed the scope defined by the claims, they shall all fall within the protection scope of the present invention.
