[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] The prior art relates to the safety monitoring technology of the ladder, which is realized by a single technical means. The single technical means will bring the problem of the false operation of the operator. For example, in the power grid operation, when the ladder is used for climbing operation, another operator is required to hold the ladder to ensure the stability of the ladder and the safety of the climber. If no one holds the ladder during the climbing operation, it is a violation of the operation. If only a single detection method is used, the operator can cheat the image recognition detection by pretending to hold and not using force, or actually detecting the pressure acting on the surface of the ladder in the vertical direction, which is actually achieved by relying on other external force to cheat the detection. Therefore, how to more comprehensively and accurately monitor the safety of climbing the ladder, the present application provides a ladder climbing safety detection method. In order to clearly describe the ladder climbing safety detection method provided by the embodiment, please refer to Figure 1 , including steps S110-S130.

[0031] Step S110: acquiring monitoring information and state information of the ladder, the monitoring information being the video or image of the operation site where the ladder is located collected by the camera device, and the state information including at least one of load information, pressure information and inclination information.

[0032] In an embodiment, the ladder climbing safety detection method provided by the present application needs to install corresponding sensors on the ladder to acquire the state information. The state information includes at least one of load information, pressure information and inclination information, that is, at least one of a load sensor, a pressure sensor and an inclination sensor is installed on the ladder. Specifically, the installation position and installation requirements of each sensor on the ladder will be described in detail later, which will not be expanded here. As for the specific content included in the state information: the load information is the information of the size of the load received by the ladder in the longitudinal direction, which can be used as a basis for judging whether the ladder is used for climbing operation; the pressure information is the information of the size of the pressure perpendicular to the surface of the ladder received at the installation position of the pressure sensor, so as to determine whether the ladder is held or gripped by someone at a specific position; the inclination information is the information of the size of the angle between the ladder and the horizontal plane, which indicates the safety and stability of the angle of the ladder. The monitoring information can be the monitoring video or image collected by the camera device at the operation site where the ladder is located. Specifically, the camera device can be a monitoring device such as a surveillance ball, which is not limited. It should be noted that there are two kinds of personnel during the operation of the ladder, one is the operator located on the ladder to implement the operation, and the other is the personnel located below the ladder to hold the ladder to keep the ladder stable and safe, which is the ladder holding personnel. It can be understood that since the safety of the ladder is mainly realized by the control of the ladder holding personnel, the subsequent detection is mainly used to detect the action of the ladder holding personnel.

[0033] Step S120: determining whether the ladder is in the working state according to the state information and the monitoring information.

[0034] In an embodiment, in step S120: determining whether the ladder is in the working state according to the state information and the monitoring information, it includes: when the monitoring information detects that the working personnel is performing the ladder climbing behavior on the ladder and the load information is higher than the preset load threshold, it is determined that the ladder is in the working state.

[0035] In an embodiment, it can be understood that through the state information of the ladder itself and the monitoring information collected by the third party externally, it can be determined whether the ladder is in the working state through a more comprehensive angle, so as to more accurately monitor the safety of the ladder climbing. Therefore, as described above, for whether the ladder is in the working state, it needs to be evaluated through the two aspects of itself and the outside, and the specific condition can be that the load information changes and is higher than the preset load threshold; and through the monitoring information, through image recognition and other technologies, it is determined that the personnel has performed the ladder climbing behavior on the corresponding ladder, then it can be determined that the ladder is in the working state. And further, in order to prevent misjudgment, the time condition can also be added in the two conditions, for example, the corresponding time threshold is also met, that is, it needs to exceed a certain time, then it can be determined that the ladder is currently in the working state, so as to prevent the misjudgment caused by the collision between the personnel or other objects and the ladder in some cases, and increase the accuracy of the judgment.

[0036] In an embodiment, in step S120: determining whether the ladder is in the working state according to the state information and the monitoring information, it includes: when the monitoring information detects that the working personnel has the ladder climbing behavior, but the load information is lower than or equal to the preset load threshold, or the monitoring information does not detect that the working personnel has the ladder climbing behavior, but the load information is higher than the load threshold, a third warning information is generated and outputted to inform the supervisor to pay attention to the manual observation of the working site.

[0037] In an embodiment, when judging whether the ladder is in the working state according to the foregoing, both the internal and external conditions need to be satisfied at the same time to determine. If neither of the two conditions is satisfied at the same time, it can be understood that the ladder is not in the working state. However, if only one of the conditions is satisfied, it is possible that other unexpected situations occur, which need to be noticed. That is to say, when the monitoring information detects that the working personnel has the ladder climbing behavior, but the load information is lower than or equal to the preset load threshold; or, according to the monitoring information, no ladder climbing behavior of the working personnel is detected, but the load information is higher than the load threshold. It belongs to the situation that needs to be noticed. For the former, there is a ladder climbing behavior, but there is no actual load, which indicates that there may be children playing in the scene; for the latter, there is no ladder climbing behavior, but there is an actual load, which indicates that there may be a heavy object falling and pressing the ladder. Therefore, in the two cases, the third early warning information can be generated and output to the on-site personnel, for example, the on-site supervisor, to inform them to pay attention to manual observation of the working site, so as to timely solve and clear up when there is an abnormal situation, thereby avoiding the occurrence of other accidents or risks, improving the safety of the working site and the service life of the ladder.

[0038] Step S130: When the ladder is in the working state, the safety coefficient of the ladder climbing work is determined according to the state information and the monitoring information, and the safety coefficient is outputted.

[0039] In an embodiment, when it is determined that the ladder is in a working state, a safety factor of the ladder working is determined according to the state information and the monitoring information to determine whether the ladder is in a safe working state at present and corresponding prompt information is output. Specifically, the ladder can be evaluated by pressure information and inclination information from two aspects. The former is used to determine whether the ladder is operated by the ladder personnel according to the predetermined rules and requirements; the latter is used to determine whether the current inclination of the ladder can provide good support and stability for the ladder. The two are independent of each other, so different judgments are needed to determine the safety factor to finally determine whether to output and what to output. The specific evaluation will be described in detail below. The safety factor is a means for evaluating whether the ladder is in a safe state at present, which can be a numerical value or a ladder form, and is not specifically limited. In this embodiment, for the convenience of understanding, the safety factor is divided into three stages of high, medium and low. When the safety factor is high, it indicates that the operation performed by the ladder personnel conforms to the regulations, and the ladder personnel and the working personnel have high safety, so no output or prompt information can be output to inform the ladder personnel to maintain the operation to maintain the safety of the work. When the safety factor is medium, it indicates that the ladder is in a certain risk, and the ladder personnel does not correctly perform the corresponding operation, so a warning information can be output to inform the ladder personnel to correct in time to reduce and correct the risk. Finally, if the safety factor is low, it indicates that the ladder working has a great risk of safety accidents, and the ladder personnel or completely does not perform the corresponding operation, so an alarm information needs to be output to inform the user to immediately perform or check the safety of the ladder to avoid the occurrence of safety accidents. In order to play a role in warning others, a violation record can also be made when the alarm information is output, and the time, place, violator, violation behavior and on-site monitoring information at that time are recorded for subsequent secondary evaluation by the supervision personnel to avoid misjudgment when there is no accident risk; and the evidence is kept to play an educational and warning role subsequently when there is indeed a risk.

[0040] In an embodiment, in step S130, when the ladder is in the working state, the safety coefficient of the ladder climbing work is determined according to the state information and the monitoring information, and the output is performed according to the safety coefficient, including: when the pressure information is greater than or equal to the preset pressure threshold value, and the monitoring information detects that the escalator personnel has the escalator action, it is determined that the safety coefficient is high, and the first prompt information is output to inform the escalator personnel to keep the escalator action; when the pressure information is less than the pressure threshold value, and the monitoring information detects that the escalator personnel has the escalator action, it is determined that the safety coefficient is medium, and the first early warning information is output to inform the escalator personnel to check the pressure sensor; when the pressure information is greater than or equal to the pressure threshold value, and the monitoring information does not detect that the escalator personnel has the escalator action, it is determined that the safety coefficient is medium, and the second early warning information is output to inform the escalator personnel to correctly perform the escalator action; when the pressure information is less than the pressure threshold value, and the monitoring information does not detect that the escalator personnel has the escalator action, it is determined that the safety coefficient is low, and the first alarm information is output to inform the escalator personnel to perform the escalator action, and record the illegal information.

[0041] In an embodiment, the present embodiment is mainly aimed at the safety monitoring of whether the escalator personnel has performed the escalator action. The detection of the escalator action can be divided into two levels, one is whether to perform, and the other is whether to perform correctly. Therefore, two kinds of basis need to be obtained for judgment, one is to restore the action information of the escalator personnel through the image recognition technology in the monitoring information, to determine whether the escalator personnel has performed the escalator action, and whether the performed escalator action conforms to the corresponding standard. Further, in order to prevent misjudgment and false behavior of the escalator personnel, pressure information also needs to be obtained to determine whether the escalator personnel has gripped the ladder according to the regulations to exert enough force on the ladder to ensure the stability and safety of the ladder. Therefore, in a preferred embodiment, the escalator personnel needs to meet two conditions of correct performance of the body action and the pressure information exerted on the escalator pressure sensor being greater than or equal to the preset pressure threshold value, so as to determine that the safety coefficient is high, proving that the escalator personnel has performed the corresponding operation according to the regulations. If one of the judgment results of whether there is an escalator action through image recognition of the monitoring information or the comparison result of the pressure information and the pressure threshold value does not meet the regulations, then the safety coefficient can only be determined as medium. It is identified that the escalator personnel has performed the escalator action, but has not performed the escalator action correctly, or has the possibility of false escalator behavior. Finally, if both of the two basis do not meet the standard, that is, the pressure information is less than the pressure threshold value, and the monitoring information does not detect the escalator action of the escalator personnel, it means that the escalator personnel has not performed the escalator action at all, and the escalator operation has a high risk of safety accident. Further, according to the safety coefficient, the corresponding information can be output, as described above, for the detection situation of the escalator action. The output content can be: when the safety coefficient is high, the first prompt information is output to inform the escalator personnel to maintain the escalator action; when the safety coefficient is high, the second warning information is output to inform the escalator personnel to perform the escalator action correctly; when the safety coefficient is low, the first alarm information is output to inform the escalator personnel to perform the escalator action, and the violation information is recorded. By taking the monitoring information and the pressure information as the judgment basis, it is determined whether the escalator personnel has performed the escalator action correctly, which avoids false, misjudgment and other situations, more accurately determines the safety state of the escalator, and outputs the prompt information accordingly, so as to understand the situation and maintain the correct execution in the correct execution; in the incorrect or non-execution situation, timely remind to correct or perform the escalator action, to ensure the operation safety of the escalator operation personnel, and reduce the risk of accident.

[0042] In an embodiment, in step S130: when the ladder is in the operation state, the safety coefficient of the escalator operation is determined according to the state information and the monitoring information, and the output is performed according to the safety coefficient, including: matching the corresponding safety coefficient according to the inclination information; when the safety coefficient is high, the second prompt information is output to inform the escalator personnel to maintain the inclination state of the ladder; when the safety coefficient is low, the second alarm information is output to inform the escalator personnel to adjust the inclination state of the ladder, and the violation information is recorded.

[0043] In an embodiment, the embodiment is for judging the inclination angle case. It can be understood that the ladder is supported on a certain support and has a certain angle with the horizontal direction, and the placing angle of the ladder can be determined by the inclination angle information. For example, the inclination angle threshold can be used, if the inclination angle is greater than the inclination angle threshold, the matching safety coefficient is high; if the inclination angle is less than or equal to the inclination angle threshold, the matching safety coefficient is low. The inclination angle threshold is a value determined according to the actual situation and the ladder state, which is only described here and is not specifically limited. Similar to the escalator behavior detection, when the safety coefficient is high, the second prompt information is output to inform the escalator personnel to keep the inclination angle of the ladder; when the safety coefficient is low, the second alarm information is output to inform the escalator personnel to adjust the inclination angle of the ladder, and the illegal information is recorded.

[0044] In an embodiment, as described above, the escalator behavior detection and the inclination angle size detection are two safety coefficient determination processes. In the foregoing, they are independent determination processes, but in an embodiment, they can be combined to jointly determine and determine the safety coefficient, for example, the lowest of the two is the actual safety coefficient and is output; or the actual safety coefficient is determined by superimposing the two. The actual combination of the two can produce complex and variable situations, which is difficult to enumerate, so the above is only a simple description of the technology, not a limitation of the technical solution, and the actual situation is not limited to this. Therefore, in the embodiment, the safety coefficient can be determined and output by the two ladder climbing safety detection methods of the escalator behavior detection and the inclination angle size detection, so as to more accurately determine the current working safety situation of the escalator to ensure the safety of the workers. At the same time, the output prompt information, warning information and alarm information need to be output to the corresponding personnel, for example, the above three kinds of information can be output to the escalator personnel, and the alarm information can also be output to the supervisor. The specific implementation of the above output can be output by the output module installed on the ladder to correspond to the output including but not limited to text, sound, light, image and other information to inform the escalator personnel. It can also be a mobile terminal of the relevant personnel, specifically, the mobile terminal can be but not limited to a mobile phone, a tablet computer, a personal digital assistant (English: personal digital assistant, abbreviation: PDA), a mobile Internet device (English: mobile Internet device, abbreviation: MID) and a wearable device (such as a smart watch). The application (such as APP) on the mobile terminal can process and display the corresponding information, thereby improving the use efficiency. The relevant personnel can receive the corresponding output information in time to perform the corresponding operation to ensure the safety of the work.

[0045] Therefore, this application can determine whether the ladder is in operation based on the status information obtained from the ladder itself and the monitoring information collected by the remote camera device, thereby reducing misjudgments. At the same time, by combining status information and monitoring information, it can achieve comprehensive detection of whether escalator personnel are performing escalator actions in compliance with regulations, improve the reliability of safety detection, prevent escalator personnel from faking escalator actions, and ensure the safety of operators.
