Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are merely for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
The invention provides a method, a system, a medium and equipment for evaluating fatigue risk of an air traffic controller. Embodiments of the present invention will be described below with reference to the drawings.
The first embodiment:
referring to fig. 1, fig. 1 is a flowchart of an assessment method for fatigue risk of an air traffic controller according to an embodiment of the present invention, where the assessment method for fatigue risk of an air traffic controller according to the embodiment includes:
step S101: and acquiring the current fatigue parameters influencing the overall fatigue risk of the air traffic controller in the current statistical period.
Step S102: and calculating the current fatigue coefficient of the overall fatigue risk of the traffic controller in the blank space in the current statistical period according to the current fatigue parameters.
Step S103: and evaluating the overall fatigue risk of the traffic controllers in the air in the current statistical period according to the current fatigue coefficient and the historical fatigue coefficient.
The overall fatigue risk refers to the fatigue risk of a larger group of civil aviation air traffic controllers, such as a control unit or the whole industry, and is within the protection scope of the invention.
Wherein, the current statistical period refers to a current period of time, such as a month, a week, etc.
The method comprises the steps of obtaining a current fatigue parameter, calculating a current fatigue coefficient of the current stage overall fatigue risk of the air traffic controller according to the current fatigue parameter, and evaluating the overall fatigue risk of the air traffic controller according to the current fatigue coefficient and the historical fatigue coefficient, so that the method can be used for carrying out macroscopic evaluation on the fatigue risk of a large group of air traffic controllers and the fatigue risk of the whole industry at the current stage. Through the assessment of the fatigue risk of a large group, decision reference can be provided for the operators on duty and on duty of the air traffic control unit, so that the manager can supplement human resources in due time according to the fatigue risk, reasonably arrange the shift, reduce the fatigue risk of the controller, and prevent the overload and the over-capacity operation of the air traffic control unit.
In the invention, the fatigue parameters in different statistical periods are different, so the fatigue coefficients obtained by calculation are also different.
Therefore, the overall fatigue risk of traffic controllers in the air in the current statistical period can be evaluated according to the current fatigue coefficient and the historical fatigue coefficient.
Compared with the historical fatigue coefficient, the current fatigue coefficient is in an increasing trend, which indicates that the overall fatigue risk of air traffic controllers is increased, the per-capita guarantee time is longer, the possibility of fatigue generation of the controllers during duty is increased, and the coefficient is reduced by adopting modes of timely supplementing human resources, reasonably scheduling and the like. For the empty pipe operation unit with a high fatigue coefficient of the controller, further fatigue detection and speculation work of the controller should be carried out, the fatigue degree and the generation mechanism of the controller are deeply grasped, effective fatigue control measures of the controller are taken, the fatigue condition of the controller is improved, and the fatigue risk of the controller is reduced.
For example, the current statistical period is a current week, and the historical fatigue coefficients may include the fatigue coefficients calculated for the statistical period of the last week, and the like.
In the present invention, the method of calculating the historical fatigue coefficient is the same as the method of calculating the current fatigue coefficient. This is comparable. For example, the current fatigue coefficient is calculated by using three parameters, namely daily average guaranteed number, single average guaranteed time and total number of on duty controllers, and the historical fatigue coefficient is also calculated by using the three parameters, and the three parameters should be obtained in the same manner.
In the invention, the fatigue parameters can comprise daily average guaranteed number of stands, single average guaranteed time, total number of on-duty controllers and other statistics.
The current fatigue parameters may include: and the daily average guaranteed number, the single average guaranteed time, the total number of the on-duty controllers and other statistics in the current statistical period.
Preferably, the fatigue parameters comprise daily average guaranteed number of stands, single average guaranteed time and total number of on-duty controllers. By adopting the three typical and representative parameters, the overall fatigue risk of the controller of the control unit is calculated and evaluated. The algorithm is simple and easy to implement, and has practicability.
The daily average guaranteed number of shelves is the daily average number of shelves of the air traffic control service provided by the civil aviation air traffic control unit for the flight activities in the current statistical period.
The single-frame average guarantee time refers to the single-frame average time length of the air traffic control service provided by the civil aviation air traffic control operation unit for the flight activities in the current statistical period.
The total number of the on-duty controllers is the total number of the license controllers of the civil aviation air traffic control operation unit, wherein the on-duty time of the civil aviation air traffic control operation unit reaches a time threshold value in the current statistical period. Preferably, the time threshold is 40% of the average on duty time. The time threshold may take other values, which are within the scope of the present invention.
The mode of acquiring three fatigue parameters of daily guaranteed number of stands, single-stand average guaranteed time and total number of on-duty controllers is as follows:
(1) daily guarantee of the number of times of the shelf:
when daily guaranteed number of shelves is obtained, the daily guaranteed number of shelves can be obtained through manual statistics, automatic statistics and other modes.
(2) Single-frame average guarantee time:
the single-frame mean guarantee time is obtained by at least one of the following modes:
acquiring single-frame average guarantee time influencing the overall fatigue risk of an air traffic controller in the current statistical period according to the distribution proportion of the traffic flow of the airway route and the empirical flight time in the current statistical period;
acquiring single-frame average guarantee time influencing the overall fatigue risk of an air traffic controller in the current statistical period according to the traffic flow distribution proportion and the experience sliding time of the sliding route of the airport maneuvering area in the current statistical period;
acquiring single-frame average guarantee time influencing the overall fatigue risk of an air traffic controller in the current statistical period according to the air traffic control automation system comprehensive track real-time data in the current statistical period;
and acquiring the average guarantee time of a single frame influencing the overall fatigue risk of the air traffic controller in the current statistical period according to the real-time data of the production system in the current statistical period.
The first mode is as follows: and roughly estimating the single average guarantee time in the regional control service and the approaching control service based on the distribution proportion of the traffic flow of the airway route and the checked flight time in the current statistical period.
The second mode is as follows: and roughly estimating the single average guarantee time in the airport control service based on the traffic flow distribution proportion and the empirical sliding time of the sliding route in the airport maneuvering area in the current statistical period.
The third mode is as follows: and collecting the comprehensive flight path real-time data of the air management automation system in the current statistical period, and accurately measuring and calculating the single average guarantee time in the regional control service and the approaching control service according to the real-time data.
The fourth mode is that: the method comprises the steps of collecting real-time data of one or more production systems in an advanced scene guidance control system, a flow management system, a tower electronic progress single system and the like in a current statistical period, and accurately measuring and calculating the average guarantee time of single stands in airport management service.
When the average guarantee time of a single frame is obtained, the average guarantee time can be obtained by any one of the above methods, or by a combination of multiple methods, which is within the protection scope of the present invention.
(3) The total number of the on duty controllers is as follows:
in the present invention, the obtaining of the current fatigue parameter affecting the overall fatigue risk of the air traffic controller in the current statistical period includes: acquiring the total number of the on-duty controllers influencing the whole fatigue risk of the air traffic controllers in the current statistical period; the total number of the on-duty controllers influencing the whole fatigue risk of the air traffic controllers in the current statistical period is obtained, and the method comprises the following steps: counting the on-duty time of traffic controllers in the air in the current counting period; acquiring the average level of the on-duty time of traffic controllers in the air in the current statistical period; and counting the total number of the on-duty controllers influencing the overall fatigue risk of the air traffic controllers in the current statistical period based on the on-duty time and the average level.
Wherein, the obtaining of the average level of the on duty time of the traffic controllers in the air in the current statistical period comprises: and acquiring the average level of the on-duty time of the traffic controllers in the air in the current statistical period according to one or more of the open time of the posts, the number of the license controllers and the records of the on-duty personnel in the current statistical period.
For example, one or more of the following schemes may be used to obtain the average on duty time level:
the first method comprises the following steps: a rough estimate is made based on the post (seat) open time and the number of license regulators within the published current statistics period.
And the second method comprises the following steps: and acquiring the open time of the post (seat) and the records of the personnel on post based on the on-duty log or the account book in the current statistical period, and checking, measuring and calculating.
And the third is that: and acquiring the post (seat) opening time and post-on personnel records by using a field recording and video recording system based on the management in the current statistical period, and checking, measuring and calculating.
And fourthly: collecting system logs of an air management automation system and the like in the current statistical period to obtain post (seat) open time and post-on personnel record data, and accurately measuring and calculating.
After the average level of the duty-on duty time is calculated, the total number of the duty controllers can be calculated according to the average level and the counted duty-on time of the traffic controllers in the air in the current counting period.
Since the total number of the on-duty controllers is the total number of the license controllers of the air traffic control unit when the on-duty time reaches the time threshold value in the current statistical period, when the time threshold value is 40% of the average level of the on-duty time, the total number of the on-duty controllers is the total number of the license controllers of the air traffic control unit when the on-duty time reaches the average level of 40% in the current statistical period.
In the invention, after three fatigue parameters of daily guaranteed number of shelves, single-shelf average guaranteed time and total number of on duty controllers are obtained, the fatigue coefficient of the whole fatigue risk of the air traffic controller can be calculated according to the three parameters, and the calculation formula is as follows:
fatigue coefficient (average guaranteed daily quantity per average guaranteed time per single guaranteed time)/total number of controllers on duty
In the invention, after the fatigue coefficient is calculated, the fatigue coefficient can be verified and rechecked in a sampling mode, so that the objectivity and the accuracy of the overall fatigue coefficient of the controller reported by each unit can be ensured.
In order to improve the data acquisition quality, the fatigue parameters can be obtained based on an accurate measuring and calculating method of real-time data mining, and further more accurate fatigue coefficients are obtained.
In the invention, the evaluation result indicates that the air traffic controller has fatigue risk as a whole, and an improvement scheme for reducing the fatigue coefficient can be predicted according to the current fatigue coefficient; and transmits the improvement to the user.
Wherein, the improvement scheme can include: human resources, scheduling conditions, airfield traffic, etc. that need to be replenished. All within the scope of the invention.
The predicted improvement scheme can provide decision reference for the operators on duty of the empty pipe operation unit, and prevent the empty pipe operation unit from overload and excess capacity operation.
In the invention, the updating period can be set as required, the fatigue coefficient is calculated periodically, the overall fatigue risk of the air traffic controller is further evaluated periodically, and more timely fatigue information is provided for the air traffic controller.
The invention provides the method for evaluating the fatigue risk of the air traffic controller.
