Description

Technical Field

[0001] This invention relates to the field of safety equipment for high-altitude operations in power equipment, and more specifically, to an alarm method and alarm device for a safety belt buckle. Background Technology

[0002] In the power industry, substation maintenance and repair work often requires personnel to work at heights. To ensure the safety of these workers, safety belts are essential protective equipment. However, traditional safety belts primarily provide physical protection, requiring workers to ensure they are wearing them properly. Manual checks by workers or supervisors are necessary to verify the safe use of safety belts at heights. However, the accuracy of manual checks is low, and this cannot guarantee the safety of workers at heights.

[0003] Currently, some safety belt status monitoring devices for high-altitude operations have appeared on the market. For example, some devices use a power supply and a buzzer installed on the safety belt buckle. When the safety belt buckle does not form a closed loop, the buzzer emits a beeping sound; when the safety belt buckle forms a closed loop, the buzzer short-circuits and stops emitting a sound. However, this method also fails to produce a sound when the buckle connection is not secure, such as when it is lapped. In other words, existing technology still cannot achieve stable detection of the safety belt buckle's engagement state, which can easily pose a danger to the work and personal safety of workers.

[0004] Therefore, existing technologies have a technical problem: safety belts cannot detect the fixed state of the buckles, which leads to safety hazards for workers operating at heights. Summary of the Invention

[0005] The main objective of this invention is to provide an alarm method and device for seat belt buckles, in order to solve the technical problem that the existing technology cannot detect the fixed state of the seat belt buckle, thus causing safety hazards for workers working at heights.

[0008] In some implementations, determining the state information of the seatbelt buckle based on the safety parameter information includes: determining the rate of change of magnetic flux around the seatbelt buckle based on the safety parameter information; and determining the state information of the seatbelt buckle based on the rate of change of magnetic flux.

[0009] In some embodiments, before generating the alarm message for the seat belt based on the safety level, the method further includes: obtaining pressure information of the buckle groove of the seat belt; verifying the safety level based on the pressure information; and updating the safety level when the pressure information is inconsistent with the safety level.

[0010] In some embodiments, obtaining the pressure information of the seat belt buckle's engagement slot includes: detecting the pressure value of the seat belt engagement slot; and determining the pressure information at the seat belt engagement slot based on the pressure value.

[0011] In some embodiments, determining the pressure information at the seatbelt buckle slot based on the pressure value includes: amplifying and filtering the pressure value, wherein the filtering process employs a moving average filtering algorithm, and the expression for the moving average filtering algorithm is:

[0012] y(k)=c1y(i)+c2y(i-1)+…+c m y(i-m+1);

[0013] In the formula, y(k) represents the filtered output at the k-th sampling time, each y(i) represents the signal input at the i-th sampling time, the number i in parentheses represents the i-th sampling time, and c1, c2, ..., c m is the weighting coefficient, and m is the length of the average window.

[0014] In some implementations, after generating the alarm message for the seat belt based on the safety level, the method further includes: obtaining the location information of the seat belt; and sending the alarm message to the interactive workstation closest to the location information.

[0015] According to another aspect of the present invention, the present invention also provides an alarm device for a seat belt buckle, comprising: an acquisition module for acquiring safety parameter information of the seat belt buckle, wherein the safety parameter information includes at least the magnetic flux of the seat belt buckle; a first determination module for determining state information of the seat belt buckle based on the safety parameter information; a second determination module for determining the safety level of the seat belt buckle based on the state information; and a generation module for generating alarm prompt information of the seat belt based on the safety level.

[0016] According to another aspect of the present invention, the present invention also provides a storage medium storing a computer program, which, when executed by a processor, implements the steps of the alarm method for the seatbelt buckle as described in any of the preceding claims.

[0017] According to another aspect of the present invention, the present invention also provides an electronic device, including at least a memory and a processor, wherein the memory stores a computer program, and the processor, when executing the computer program in the memory, implements the steps of the alarm method for the seat belt buckle as described in any of the preceding claims.

[0037] The present disclosure will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] To address the technical problem in existing technologies where safety belts cannot detect the fixed state of the buckle, thus posing a safety hazard to workers performing tasks at heights, this invention provides an alarm method and device for safety belt buckles.

[0039] Example 1

[0040] like Figure 1 As shown, the alarm method for the seatbelt buckle includes the following steps:

[0041] S101, Obtain safety parameter information of the seat belt buckle, wherein the safety parameter information includes at least the magnetic flux around the seat belt buckle.

[0042] In this step, safety parameter information of the seat belt buckle is obtained, wherein the safety parameter information includes at least the magnetic flux around the seat belt buckle.

[0043] Specifically, during use, the safety belt buckle is connected to the safety belt body via the safety belt lanyard. When workers are working at heights, the safety belt buckle is secured to the suspension position via an openable closure structure. Because the safety belt buckle is within a closed loop, the magnetic flux around it changes between the open and closed states. Therefore, by acquiring information about the magnetic flux around the safety belt buckle during use, the state of the safety belt buckle can be characterized.

[0044] Of course, in order to gain a more comprehensive understanding of the seatbelt buckle status, the safety parameter information may also include pressure information, height information, and human position information.

[0045] Furthermore, such as Figure 2 As shown, obtaining the safety parameter information of the seat belt buckle includes the following steps:

[0046] S201, detects the magnetic flux around the seatbelt buckle.

[0047] In this step, the magnetic flux around the seatbelt buckle is detected. Preferably, a magnetic flux sensor or magnetometer can be used to detect the magnetic flux passing through the seatbelt buckle coil.

[0048] S202, Obtain current environmental information, wherein the environmental information includes at least the current ambient temperature and ambient humidity, and correct the magnetic flux based on the environmental information.

[0049] After completing step S201 above, in this step, current environmental information is obtained, wherein the environmental information includes at least temperature information and humidity information, and the magnetic flux is corrected based on the environmental information.

[0050] Because environmental information can affect the magnetic flux passing through the seatbelt buckle coil—for example, temperature changes can cause thermal expansion or contraction of the coil material, thus affecting the coil's geometry and the measured magnetic flux—the magnetic flux is corrected based on current temperature and humidity information after it is detected passing through the seatbelt buckle coil. The influence of temperature and humidity information on the seatbelt buckle is obtained through calibration. After acquiring the temperature and humidity information, the obtained magnetic flux is corrected based on the detected magnetic flux and the calibration information, thereby eliminating the influence of temperature and humidity changes on the magnetic flux.

[0051] S102, determine the status information of the seat belt buckle based on the safety parameter information.

[0052] After completing step S101 above, in this step, the status information of the seat belt buckle is determined based on the safety parameter information.

[0053] Furthermore, Figure 3 This diagram illustrates the method for determining the status information of the seatbelt buckle based on the safety parameter information as described in this disclosure. Figure 3 As shown, determining the status information of the seatbelt buckle based on the safety parameter information includes the following steps:

[0054] S301, determine the rate of change of magnetic flux around the seat belt buckle based on the safety parameter information.

[0055] In this step, the rate of change of magnetic flux around the seatbelt buckle is determined based on the safety parameter information.

[0056] Specifically, after acquiring the magnetic flux around the seat belt buckle, the magnetic flux data is fitted to obtain the change curve of the magnetic flux relative to time, thereby determining the rate of change of the magnetic flux around the seat belt buckle.

[0057] S302, determine the status information of the seat belt buckle based on the rate of change of the magnetic flux.

[0058] After completing step S301 above, in this step, the state information of the seat belt buckle is determined based on the rate of change of the magnetic flux.

[0059] Specifically, when workers connect the buckles of the safety belt, the magnetic flux changes as the buckles are joined together. If the buckles have poor contact, the magnetic flux will continue to change. In other words, when the safety belt buckles have poor contact, the continuous switching on and off will cause a continuous change in magnetic flux. Therefore, the contact status of the safety belt buckles can be determined by observing the change in the rate of change of magnetic flux.

[0060] S103, determine the safety level of the seat belt buckle based on the status information.

[0061] After completing step S102 above, in this step, the safety level of the seat belt buckle is determined based on the status information.

[0062] Specifically, after determining the status information of the seat belt buckle based on the rate of change of the magnetic flux, if the seat belt buckle has good contact, the safety level of the seat belt is considered high; if the seat belt buckle has poor contact, the safety level of the seat belt is considered low.

[0063] S104, generate an alarm message for the seat belt based on the safety level.

[0064] After completing step S103 above, in this step, an alarm message for the seat belt is generated based on the safety level.

[0065] Furthermore, after determining the safety level of the seat belt buckle, if the seat belt level is low, an alarm message indicating that the seat belt status needs to be checked is generated; if the seat belt safety level is high, a message indicating that the seat belt status is good is generated.

[0066] Specifically, the safety belt is equipped with an audible alarm unit and an indicator light unit. The audible alarm unit sounds an alarm when the safety belt status needs to be checked, thereby reminding the worker to pay attention. The indicator light unit is used to display the status of the safety belt, indicating different levels of safety belt safety through different colors. For example, when the safety belt safety level is high, the green indicator light is lit, and when the safety belt status needs to be checked, the red warning light is lit to send a reminder message to the worker.

[0067] According to the alarm method for seat belt buckles provided in this disclosure, safety parameter information of the seat belt buckle is acquired, the status information of the seat belt buckle is determined based on the safety parameter information, and the safety level of the seat belt buckle is determined based on the status information. Alarm information for the seat belt is then generated based on the safety level. Applying the alarm method for seat belt buckles of this disclosure ensures a good buckle connection, prevents buckle malfunctions and connection failures, and automatically alerts workers through alarm sounds and light effects, greatly improving the safety of seat belt use.

[0068] To improve the accuracy of detecting the status information of the seat belt buckle, in another embodiment of this application, before generating the alarm information of the seat belt based on the safety level, the method further includes: updating the safety level based on the pressure information of the seat belt buckle engagement groove.

[0069] Specifically, such as Figure 4 As shown, updating the safety level based on the pressure information of the seatbelt buckle slot includes the following steps:

[0070] S401, Obtain the pressure information of the seat belt buckle slot.

[0071] In this step, pressure information of the seat belt buckle engagement groove is obtained. Specifically, a pressure sensing module is installed inside the seat belt buckle. Preferably, the pressure sensing module can be a pressure sensor, which can monitor the pressure on the contact surface inside the engagement groove.

[0072] Furthermore, such as Figure 5 As shown, obtaining the pressure information of the seat belt buckle's engagement groove includes the following steps:

[0073] S501, Detect the pressure value of the seat belt buckle slot.

[0074] In this step, the pressure value of the seat belt buckle groove is detected, wherein the pressure value is the pressure borne by the inner abutment surface of the buckle groove.

[0075] S502, determine the pressure information at the seat belt buckle slot based on the pressure value.

[0076] After completing step S501 above, in order to enhance the signal strength and more clearly sense the connection status of the seat belt buckle, this step amplifies and filters the pressure value to determine the pressure information at the seat belt buckle slot. The filtering process employs a moving average filtering algorithm, the expression of which is:

[0077] y(k)=c1y(i)+c2y(i-1)+…+c m y(i-m+1);

[0078] In the formula, y(k) represents the filtered output at the k-th sampling time, each y(i) represents the signal input at the i-th sampling time, the number i in parentheses represents the i-th sampling time, and c1, c2, ..., c m is the weighting coefficient, and m is the length of the average window.

[0079] Using an average filtering algorithm to assist in the processing of pressure detection data can make the system detection results more accurate. At the same time, the cooperation of multiple modules in the entire system can effectively improve the system's flexibility and scalability.

[0080] S402, The safety level is checked based on the pressure information.

[0081] After completing step S401 above, in this step, the safety level is checked based on the pressure information. Specifically, when the safety belt buckle is properly engaged, the inner side of the buckle's engagement groove will bear the resistance force transmitted by the buckle; therefore, when the pressure sensor detects that the pressure on the engagement surface of the engagement groove is greater than a threshold, the safety belt buckle is considered to be properly engaged; when the pressure sensor detects that the pressure on the engagement surface of the engagement groove is less than the threshold, the safety belt buckle is considered to be poorly engaged. The threshold is determined based on the personnel and equipment working at height.

[0082] S403, when the pressure information is inconsistent with the safety level, update the safety level.

[0083] Specifically, after verifying the safety level in step S402, if the verified safety level is inconsistent with the safety level of the seat belt buckle determined based on the status information, the safety level is updated. In other words, it is necessary to verify the safety level of the seat belt buckle determined based on the status information, prompting operators to pay attention.

[0084] To achieve coordinated ground and air operations, in another embodiment of the present invention, after generating the alarm message for the seatbelt based on the safety level, as follows: Figure 6 As shown, the method further includes the following steps:

[0085] S601, Obtain the position information of the seat belt.

[0086] In this step, the location information of the safety belt is obtained. Specifically, since the position of the workers is constantly changing during high-altitude power line inspections, in order to accurately determine the position of the workers, the precise location information of the safety belt is obtained through a GPS receiver unit in this step. By receiving the position information of the safety belt buckle, the position of the workers can be accurately located and displayed on the control platform of a remote control center located on the ground.

[0087] S602, the alarm notification information is sent to the interactive workstation closest to the location information.

[0088] After completing step S601 above, in this step, the alarm notification information is sent to the interactive workstation closest to the location information.

[0089] Specifically, after obtaining the location of the workers, the location can be shared with the interactive workstation. Workers at the interactive workstation can see the workers' location on a monitor and determine the distance between the workers and the workstation. Workers at the workstation closest to the workers can interact with them, sending alarm messages or assisting them in checking the safety status of their safety harnesses.

[0090] By sharing location information with the interactive workstation, communication between the workers and the workstation is achieved. This allows ground staff to promptly detect any abnormalities in the safety belt and proactively activate the alarm module to alert the workers at height. This enables ground staff to provide better support and significantly improves the safety of the workers.

[0091] Of course, to further improve the safety of workers, the height information of the workers' location can also be obtained. The height information is used to represent the height of the workers from the ground during the work process. The staff at the interactive workstation can send prompt information to the workers after comprehensively considering the workers' location, height and other information. By obtaining location, height and other information, the working status of the workers can be more comprehensively reflected, which is conducive to further improving the safety of the workers during the work process.

[0092] Example 2

[0093] To better implement the above methods, a second aspect of this disclosure also provides an alarm device for a seatbelt buckle, which can be integrated into an electronic device.

[0095] (1) Acquisition module 210, the acquisition module 210 is used to acquire safety parameter information of seat belt buckle, wherein the safety parameter information includes at least the magnetic flux of seat belt buckle.

[0100] Furthermore, the first determining module 220 includes a first determining unit and a second determining unit, wherein the first determining unit is used to determine the rate of change of magnetic flux around the seat belt buckle based on the safety parameter information, and the second determining unit is used to determine the state information of the seat belt buckle based on the rate of change of magnetic flux.

[0101] Furthermore, the alarm device 200 also includes an update module, which is used to update the safety level based on the pressure information of the seat belt buckle slot.

[0102] The update module includes a first acquisition unit, a verification unit, and an update unit. The first acquisition unit is used to acquire pressure information of the seat belt buckle's engagement groove. The verification unit is used to verify the safety level based on the pressure information. The update unit is used to update the safety level when the pressure information is inconsistent with the safety level.

[0103] Furthermore, the update module is also used to detect the pressure value of the seat belt buckle slot and determine the pressure information at the seat belt buckle slot based on the pressure value.

[0104] The step of determining the pressure information at the seatbelt buckle slot based on the pressure value includes: amplifying and filtering the pressure value, wherein the filtering process uses a moving average filtering algorithm, and the expression of the moving average filtering algorithm is:

[0105] y(k)=c1y(i)+c2y(i-1)+…+c m y(i-m+1);

[0106] In the formula, y(k) represents the filtered output at the k-th sampling time, each y(i) represents the signal input at the i-th sampling time, the number i in parentheses represents the i-th sampling time, and c1, c2, ..., c m is the weighting coefficient, and m is the length of the average window.

[0107] Furthermore, the alarm device is also used to acquire the location information of the seat belt; and send the alarm notification information to the interactive workstation closest to the location information.
