Description

Technical Field

[0001] The present application relates to the technical field of risk prevention and control, and in particular, to a risk prevention and control method system and an electronic device. Background Art

[0002] Refueling an aircraft is a high-intensity task. It is necessary to timely determine the fatigue level of the refueler so that the fatigued refueler can rest in time and avoid over-fatigue at work. Existing methods rely on dispatchers to manually count the workload of refuelers to judge the fatigue level of refuelers.

[0003] In the actual refueling process, the work of dispatchers is heavy, and it is difficult to obtain comprehensive refueling data of each refueler, so it is impossible to accurately determine the fatigue level of each refueler. Therefore, it is very likely that the dispatcher will allocate refueling tasks unreasonably, causing refuelers to be over-fatigued, the refueling tasks cannot be completed on time, and there may also be uncontrollable accidental risks due to fatigue. In addition, setting up a calculation system that can determine the work fatigue of refuelers also greatly ensures the safety measures during the work process, and can also coordinate the work burden, so as to focus on the guarantee work of flights.

[0064] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by those of ordinary skill in the art without creative efforts belongs to the scope of protection of the present application.

[0065] First, the applicable application scenarios of the present application are introduced. The present application can be applied to determining the fatigue degree of fuelers at an airport.

[0066] Through research, it is found that the existing determination method relies on dispatchers to manually count the workload of fuelers to determine the fatigue degree of fuelers. This judgment method relying on the manual statistics of dispatchers increases the workload of dispatchers, making dispatchers unable to focus on ensuring flights. In addition, it is very likely that the judgment of the fatigue degree of fuelers is inaccurate, resulting in fuelers being over-fatigued, damaging the physical health of fuelers, and even causing safety accidents.

[0067] Based on this, the embodiments of the present application provide a risk prevention and control method to make the determined fatigue degree of fuelers more accurate and reasonable, which helps to reasonably arrange the refueling tasks of fuelers, reduce the workload of dispatchers, save human resources, and improve work efficiency.

[0068] Please refer to Figure 1 , Figure 1 , which is a flowchart of a risk prevention and control method provided by an embodiment of the present application. As Figure 1 shown in, the method for determining the fatigue degree of fuelers provided by the embodiments of the present application includes:

[0069] S101. Obtain the start time, end time, and refueling volume of each completed refueling task completed by the fueler on the current day, as well as the historical refueling data of the fueler within a preset time period.

[0070] In this step, when the fueler refuels a flight, it corresponds to one refueling task. The refueling system will record the start time, end time, and refueling volume of the fueler's execution of this refueling task, and generate a corresponding refueling work order after the completion of this refueling task. The historical refueling data of the fueler within a preset time period is stored in the database of the refueling system. Here, the historical refueling data includes one or more of the total refueling duration within a predetermined time period, the total refueling volume within a predetermined time period, and the total number of refueling flights within a predetermined time period. The predetermined time period can be one month, ten days, or one week. It should be understood that the predetermined time period can be adjusted according to the actual need to determine the fatigue degree, and the present application does not make any restrictions here. By querying the refueling system and the database, the start time, end time, and refueling volume of each completed refueling task completed by the fueler on the current day, as well as the historical refueling data of the fueler within a preset time period, can be obtained.

[0071] S102. Determine the total refueling data of the fueler on the current day based on the start time, end time, and refueling volume of each completed refueling task and the number of completed refueling tasks of the fueler.

[0072] Here, the total refueling data for the day includes one or more of the total refueling duration for the day, the total refueling volume for the day, and the total number of refueling flights for the day. Among them, the total refueling duration for the day refers to the total refueling duration of the fueler from the start of work on the current day until the current moment; the total refueling volume for the day refers to the total refueling volume of the fueler from the start of work on the current day until the current moment, and the refueling volume can be the weight or volume of the fuel; the total number of refueling flights for the day refers to the total number of refueling flights of the fueler from the start of work on the current day until the current moment. Each time the fueler finishes refueling one flight, one refueling task is completed, and the total number of refueling flights for the day increases by one.

[0073] In this step, the time interval between the start time and the end time of each completed refueling task is determined as the refueling duration of each completed refueling task; the sum of the refueling durations of each completed refueling task is determined as the total refueling duration for the day of the fueler; the sum of the refueling volumes of each completed refueling task is determined as the total refueling volume for the day of the fueler; the number of completed refueling tasks is determined as the total number of refueling flights for the day of the fueler; the total refueling data for the day includes one or more of the total refueling duration for the day, the total refueling volume for the day, and the total number of refueling flights for the day.

[0074] S103. Determine the continuous refueling data or rest time of the fueler according to the current working state of the fueler.

[0075] In this step, the current working state of the fueler can be determined according to the work identification or work time record of the fueler in the refueling system. Among them, the current working state includes being in the process of performing a refueling task and not being in the process of performing a refueling task.

[0076] Here, if the current working state is being in the process of performing a refueling task, then determine the continuous refueling data of the fueler; if the current working state is not being in the process of performing a refueling task, then determine the continuous refueling data or rest time of the fueler.

[0077] S104. Calculate the fatigue degree of the fueler based on the total refueling data for the day of the fueler, the historical refueling data, and the continuous refueling data or rest time of the fueler, so that the dispatcher can adjust the refueling task of the fueler according to the fatigue degree.

[0078] Here, if the current working state is being in the process of performing a refueling task, then calculate the fatigue degree of the fueler based on the total refueling data for the day of the fueler, the historical refueling data, and the continuous refueling data of the fueler; if the current working state is not being in the process of performing a refueling task, then calculate the fatigue degree of the fueler based on the total refueling data for the day of the fueler, the historical refueling data, and the continuous refueling data or rest time of the fueler.

[0079] Further, after calculating the fatigue degree of the fuel dispenser, the task status of the fuel dispenser can also be adjusted according to the fatigue degree. Here, a fatigue degree threshold can be preset in advance. When the calculated fatigue degree of the fuel dispenser is greater than or equal to the preset fatigue degree threshold, the task status of the fuel dispenser is adjusted to the fatigue state, so that the dispatcher stops assigning new refueling tasks to the fuel dispenser according to the fatigue state of the fuel dispenser; when the calculated fatigue degree of the fuel dispenser is less than the preset fatigue degree threshold, the task status of the fuel dispenser is adjusted to the standby state, so that the dispatcher continues to assign new refueling tasks to the fuel dispenser according to the standby state of the fuel dispenser.

[0080] In this way, the method for determining the fatigue degree of the fuel dispenser provided by the embodiment of the present application can calculate the fatigue degree of the fuel dispenser based on the total daily refueling data, historical refueling data, and continuous refueling data or rest time of the fuel dispenser, making the determined fatigue degree of the fuel dispenser more accurate and reasonable, which helps to reasonably arrange the refueling tasks of the fuel dispenser, reduce the workload of the dispatcher, save human resources, and improve work efficiency.

At this time, the first refueling task and the current refueling task are determined as the continuously executed refueling tasks, and proceed to S209. Wherein, the second refueling task refers to the completed refueling task with the smallest time difference between the end time and the start time of the first refueling task and ending before the start of the first refueling task; if there is a second refueling task corresponding to the first refueling task, it means that the fueler has completed at least two refueling tasks at the current moment, that is, the first refueling task and the second refueling task. At this time, proceed to S205.

Furthermore, the current refueling task and the first refueling task are determined as the refueling tasks continuously executed by the fueler, and proceed to S209.

[0094] S207. Determine whether there is a third refueling task corresponding to the second refueling task.

[0095] In this step, if there is no third refueling task corresponding to the second refueling task, it indicates that the fueler has only completed two refueling tasks at the current moment, namely the first refueling task and the second refueling task. At this time, determine the second refueling task, the first refueling task, and the current refueling task as the continuously executed refueling tasks, and enter S208. Among them, the third refueling task refers to the completed refueling task with the smallest time difference between the end time and the start time of the second refueling task and the end time before the start time of the second refueling task; if there is a third refueling task corresponding to the second refueling task, it indicates that the fueler has completed at least three refueling tasks at the current moment, namely the first refueling task, the second refueling task, and the third refueling task. At this time, enter S208.

[0096] S208. Calculate the time interval corresponding to the third time difference.

[0097] In this step, calculate the third time difference between the start time of the completed second refueling task and the end time of the third refueling task corresponding to the second refueling task, and determine the third time difference as the time interval. And so on, until the determined time interval is greater than or equal to the preset time interval or all the time intervals in the completed refueling tasks are determined.

[0098] S209. Determine the number of tasks in the continuously executed refueling tasks as the consecutive refueling trips of the fueler.

[0099] S210. Based on the current moment, the start time of each continuously executed refueling task, and the end time of each continuously executed refueling task except the current refueling task, determine the consecutive refueling duration of the fueler.

[0100] In this step, determine the time interval between the current moment and the start time of the current refueling task as the current refueling duration; determine the time interval between the start time and the end time of each continuously executed refueling task except the current refueling task as the refueling duration of each continuously executed refueling task except the current refueling task; determine the sum of the current refueling duration and the refueling duration of each continuously executed refueling task except the current refueling task as the consecutive refueling duration of the fueler.

[0106] S302. Determine whether the calculated time interval is less than the preset time interval.

[0107] In this step, if the time interval calculated in S301 is less than the preset time interval, it indicates that the fuel dispenser has at least continuously executed the first refueling task, and proceed to S303; if the time interval calculated in S301 is greater than or equal to the preset time interval, it indicates that the fuel dispenser has not continuously executed the refueling task, and then proceed to S308.
