Description

Technical Field

[0001] The present invention relates to the technical field of safety equipment for aerial work of electric power equipment, and in particular to an alarm method and an alarm device for a safety belt buckle. Background Art

[0002] In the power industry, maintenance and inspection of substations often require personnel to work at heights. To ensure the safety of personnel working at heights, safety belts are essential protective equipment. However, traditional safety belts mainly provide physical protection, requiring the operator to pay attention to the wearing of the safety belts, and the operator or supervisor to manually check whether the safety belts are used safely. However, the accuracy of manual inspection is low and cannot guarantee the safety of personnel working at heights.

[0003] At present, there are also some high-altitude work safety belt status monitoring devices on the market. For example, by setting a power supply and a buzzer on the safety belt buckle, when the safety belt buckle does not form a closed loop, the buzzer emits a beeping prompt sound. When the safety belt buckle forms a closed loop, the buzzer short-circuits and no longer emits a prompt sound. However, this method will not produce a prompt sound when the buckle is not firmly connected, for example, in the overlapping state. In other words, the existing technology still cannot achieve stable detection of the buckle connection state of the safety belt, which is easy to cause danger to the work and personal safety of the operator.

[0004] Therefore, there is a technical problem in the prior art that the safety belt cannot detect the fixing state of the buckle, which leads to a safety hazard in the high-altitude operation of the workers. Summary of the invention

[0010] In some embodiments, obtaining the pressure information of the engaging groove of the seat belt buckle includes: detecting a pressure value of the seat belt engaging groove; and determining the pressure information at the seat belt engaging groove based on the pressure value.

[0037] The present disclosure is further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] In order to solve the technical problem in the prior art that the safety belt cannot detect the fixing state of the buckle, thereby causing safety hazards when workers work at high altitudes, the present invention provides an alarm method and an alarm device for a safety belt buckle.

[0039] Example 1

[0040] like Figure 1 As shown, the alarm method of the seat belt buckle comprises the following steps:

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

[0043] Specifically, when the safety belt is in use, the safety belt buckle is connected to the safety belt body through the safety belt hanging rope. When the operator performs aerial work, the safety belt buckle is fixed in the hanging position through the openable closed structure. Since the safety belt buckle is in a closed loop, the magnetic flux around the safety belt buckle changes when it is in the open state and the closed state. Therefore, when the safety belt is in use, the state of the safety belt buckle can be characterized by obtaining the magnetic flux information around the safety belt buckle.

[0044] Of course, in order to more comprehensively understand the status information of the seat belt buckle, the safety parameter information may also include pressure information, height information, and human body position information.

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

[0046] S201, detecting the magnetic flux around the seat belt buckle.

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

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

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

[0050] Since environmental information will affect the magnetic flux passing through the buckle coil, for example, temperature changes will cause thermal expansion or thermal contraction of the coil material, thereby affecting the geometric dimensions of the coil and the measurement results of the magnetic flux. Therefore, after detecting the magnetic flux passing through the seat belt buckle coil, the magnetic flux is corrected based on the current temperature information and humidity information. Among them, the influence of temperature information and humidity information on the seat belt buckle is obtained through calibration. After obtaining the temperature information and humidity information, the obtained magnetic flux is corrected based on the detected magnetic flux and calibration information, thereby eliminating the influence of temperature and humidity changes on the magnetic flux.

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

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

[0053] Further, Figure 3 A block diagram of determining the state information of the seat belt buckle based on the safety parameter information of the present disclosure is shown as follows: Figure 3 As shown, determining the state information of the seat belt buckle based on the safety parameter information includes the following steps:

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

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

[0056] Specifically, after obtaining the magnetic flux around the seat belt buckle, the magnetic flux data is fitted to obtain a curve of the change of the magnetic flux relative to time, so as to determine the change rate of the magnetic flux around the seat belt buckle.

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

[0058] After completing the above step S301, 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 the operator connects the buckles of the seat belt, the magnetic flux will change when the buckles are spliced ​​together. If the contact of the buckles of the seat belt is poor, the magnetic flux will continue to change. In other words, when the contact of the buckles of the seat belt is poor, the continuous connection or disconnection changes will cause the magnetic flux to continue to change, so the contact condition of the buckles of the seat belt can be judged according to the change of the change rate of the magnetic flux.

[0060] S103: Determine a safety level of the seat belt buckle based on the status information.

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

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

[0063] S104: Generate the seat belt warning information based on the safety level.

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

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

[0066] Specifically, the seat belt is provided with a sound alarm unit and an indicator light unit, wherein the sound alarm unit emits an alarm sound when the seat belt status needs to be checked, thereby alerting the operator; the indicator light unit is used to display the status of the seat belt, indicating different levels of the seat belt through different colors. For example, when the safety level of the seat belt is high, the green indicator light is turned on, and when the seat belt status needs to be checked, a prompt message is sent to the operator by turning on the red warning light.

[0067] According to the alarm method for the seat belt buckle provided by the embodiment of the present disclosure, by obtaining the safety parameter information of the seat belt buckle, determining the state information of the seat belt buckle based on the safety parameter information, and determining the safety level of the seat belt buckle based on the state information, the alarm prompt information of the seat belt is generated based on the safety level. The alarm method for the seat belt buckle of the present disclosure can ensure that the buckle is in a good connection state, prevent the buckle from malfunctioning and connection failure, and automatically remind the operator through the alarm sound and light effects, which greatly improves the safety effect of the use of the seat belt.

[0068] In order to improve the accuracy of detecting the status information of the seat belt buckle, in another embodiment of the present application, before generating the alarm prompt information of the seat belt based on the safety level, the method also includes: updating the safety level based on the pressure information of the seat belt buckle engaging groove.

[0069] Specifically, Figure 4 As shown, updating the safety level based on the pressure information of the seat belt buckle engaging groove includes the following steps:

[0070] S401, obtaining pressure information of the seat belt buckle engaging groove.

[0071] In this step, the pressure information of the buckle slot of the safety belt is obtained. Specifically, a pressure sensing module is provided inside the buckle of the safety belt. Preferably, the pressure sensing module can be a pressure sensor, which can monitor the pressure on the inner side of the abutment surface of the buckle slot.

[0072] Furthermore, if Figure 5 As shown, the step of obtaining the pressure information of the engaging groove of the seat belt buckle comprises the following steps:

[0073] S501, detecting the pressure value of the seat belt engaging groove.

[0074] In this step, the pressure value of the safety belt engaging groove is detected, wherein the pressure value is the pressure borne by the inner side abutting surface of the engaging groove.

[0075] S502: Determine pressure information at the seat belt engaging groove based on the pressure value.

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

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

[0078] In the formula, y(k) represents the filter output at the kth sampling time, each y(i) represents the signal input at the ith sampling time, the number i in the brackets represents the ith sampling time, c1, c2, ..., c m is the weighting coefficient, and m is the length of the averaging window.

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

[0080] S402: Verify the security level based on the pressure information.

[0081] After completing the above step S401, in this step, the safety level is checked based on the pressure information. Specifically, when the buckle of the safety belt is properly fastened, the inner side of the buckle slot will bear the pressure transmitted by the buckle; thus, when the pressure sensor detects that the pressure on the abutment surface of the buckle slot is greater than the threshold, it is considered that the buckle of the safety belt is properly fastened; when the pressure on the abutment surface of the buckle slot detected by the pressure sensor is less than the threshold, it is considered that the buckle of the restrained safety belt is in a bad state. The threshold is determined based on the personnel and equipment working at heights.

[0082] S403: When the pressure information is inconsistent with the security level, update the security level.

[0083] Specifically, after completing the above step S402 to check the safety level, if the checked safety level is inconsistent with the safety level of the seat belt buckle determined based on the state information, the safety level is updated. In other words, the safety level of the seat belt buckle determined based on the state information needs to be checked to prompt the operator to pay attention.

[0084] In order to achieve ground-air coordination, in another embodiment of the present invention, after generating the safety belt alarm prompt information based on the safety level, as follows Figure 6 As shown, the method further comprises the following steps:

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

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

[0087] S602: Send the alarm prompt information to the interactive workstation closest to the location information.

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

[0089] Specifically, after obtaining the position of the operator, the position of the operator can be shared with the interactive workstation. The staff at the interactive workstation can see the position of the high-altitude operator through the display and determine the distance between the operator and the interactive workstation based on the position. The staff at the interactive workstation closest to the operator can interact with the operator, send alarm prompt information to the operator, or assist the operator in verifying the safety status of the safety belt.

[0090] By sharing the location information with the interactive workstation, the operators and the interactive workstation can communicate with each other, so that the ground staff can promptly discover abnormal conditions of the safety belts, and can actively start the alarm module to sound an alarm to remind the high-altitude operators. This allows the ground staff to better play an auxiliary role and greatly improve the work safety factor of the operators.

[0091] Of course, in order to further improve the safety of the staff, the height information of the operating personnel's location can also be obtained. The height information is used to characterize the height of the operating personnel from the ground during work. The staff at the interactive workstation can send prompt information to the operating personnel after comprehensively considering the operating personnel's position, height and other information. By obtaining information such as position and height, the operating status of the operating personnel can be more comprehensively reflected, which is conducive to further improving the safety of the operating personnel during the operation process.

[0101] Furthermore, the alarm device 200 further includes an updating module, and the updating module is used to update the safety level based on the pressure information of the seat belt buckle engaging groove.
