Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
In one embodiment, as shown in FIG. 1, there is provided an ergonomic assessment method comprising:
s102: and acquiring a task set of executable tasks of the sample equipment, and classifying the tasks in the task set.
Specifically, different sample devices may perform different tasks, e.g., an aircraft may perform takeoff and air cruise tasks, but an automobile may not. Therefore, when considering the task scenario constraint, it is necessary to determine a task set for the sample device to perform the task, and the sample device can be generally used for performing various types of tasks, for example, a car can be used for transportation and carrying people, but different types of cars have different purposes, resulting in different transportation capacities and different comfort levels of passengers in the car during driving. Therefore, the tasks in the task set need to be further classified to divide the task types, so as to obtain the ergonomic evaluation result of the sample device in a specific field in the following, and associate the ergonomic evaluation with the use purpose of the sample device, so that the obtained result has more referential property. For example, the use purposes of a transporter and a fighter are completely different, the transporter is mainly used for transportation, and the fighter is mainly used for combat, so that if man-machine ergonomics evaluation is performed on the transporter and the fighter, the transporter is emphasized on the man-machine ergonomics evaluation in the transportation field, the fighter is emphasized on the man-machine ergonomics evaluation in the combat field, and the obtained results can be more practical and referential by dividing tasks of transportation types and tasks of combat types and then performing the man-machine ergonomics evaluation based on the divided task types.
S104: and determining interactive elements based on the tasks and pre-stored parameters related to the interactive process, and classifying the interactive elements according to the types of the tasks corresponding to the interactive elements.
In particular, ergonomic assessment is to link the interrelationship, coordination and humanization between people, equipment, and environment. Therefore, the human-machine-environment interaction process needs to be considered, and meanwhile, the interaction process and the task need to be combined in order to join the constraint of the task environment. On the basis, the embodiment determines the interactive elements based on the parameters related to the task and the pre-stored interactive process, thereby adding the constraint of the task environment. And classifying the interactive elements, and performing human-computer ergonomics evaluation based on the types of the interactive elements, so that the obtained human-computer ergonomics evaluation result is more biased and referential obviously.
S106: and acquiring human-machine work efficiency requirements and weighted values corresponding to the interactive elements.
Specifically, each interactive element has a corresponding human-machine ergonomics requirement, the weight values of the human-machine ergonomics requirements corresponding to different interactive elements may be different, and the sum of the weight values corresponding to the interactive elements of the same type is 1. The human-machine work efficiency requirement and the weight value are determined according to the interactive elements corresponding to the human-machine work efficiency requirement and the weight value, and the human-machine work efficiency requirement and the weight value corresponding to the interactive elements can be determined only after the interactive elements are determined. The ergonomic requirement and the weight value may be determined manually or by a computer device using a corresponding algorithm, which is not limited herein.
S108: and obtaining a human-machine work efficiency evaluation result of each type of condition based on whether the task process of the sample equipment meets the human-machine work efficiency requirement corresponding to each interactive element and the weight value corresponding to each interactive element.
The task process can be realized in a simulation mode through computer equipment and also can be realized in a real test mode.
In particular, the task process of the sample device needs to be formulated based on the interactive elements due to the need to take into account the task environment constraints. Taking an airplane as an example, the interaction process comprises airplane-loop interaction, parameters related to the airplane-loop interaction process comprise daytime, the task comprises takeoff, the interaction elements obtained by daytime and takeoff are daytime takeoff, and the corresponding task process needing to be executed at least comprises daytime takeoff. After the task process is determined, whether the execution process meets the human-machine work efficiency requirement corresponding to each interactive element is judged by obtaining corresponding parameters in the task execution process of the sample equipment, and then human-machine work efficiency evaluation results of various types of conditions are obtained.
According to the man-machine work efficiency assessment method, the task set of the sample equipment executable tasks is obtained, the tasks in the task set are classified, the types of the tasks executable by the sample equipment are determined, then the interactive elements are determined according to the tasks and parameters related to the interactive process, interactive elements with dynamic characteristics are constructed, then the man-machine work efficiency assessment results of various types of conditions are obtained according to whether the task process of the sample equipment meets the man-machine work efficiency requirements corresponding to the interactive elements and the weight values corresponding to the interactive elements, so that the dynamic characteristics of man-machine interaction are fully considered, the man-machine work efficiency assessment results meet the actual work use requirements, and the man-machine work efficiency assessment effect is relatively good.
In one embodiment, classifying tasks in a task set includes:
s1021: and comparing the tasks in the task set with the tasks in the pre-stored task sets of various types in a preset sequence, and determining the types of the tasks in the task set according to the comparison result.
The task set of the sample device executable tasks is used as the sample task set, and the preset sequence can be a front-back arrangement sequence of the tasks in the sample task set.
Specifically, when tasks in the sample task set need to be classified, each pre-stored type of task set corresponding to the type of device can be determined according to the type of the sample device, and the types of the tasks in the sample task set can be obtained by comparing the tasks in the sample task set with the pre-stored types of task sets.
In the application, the tasks executable by various types of equipment can be manually determined in advance to obtain task sets of the tasks executable by various types of equipment, then the task types of the obtained task sets are divided respectively, the task sets of the subdivided task types are further obtained, and the obtained task set data are stored.
In one embodiment, determining the type of the corresponding task according to the comparison result includes:
s10211: and if the currently compared task is the same as a certain pre-stored task, judging that the type of the currently compared task is the same as that of a task set to which the pre-stored task belongs.
For example, if there are task sets of X, Y, Z, if the currently aligned task is the same as a certain task in the X task set, it may be determined that the type of the currently aligned task is the type of the X task set.
In one embodiment, classifying each interactive element according to the type of the task corresponding to each interactive element includes:
s1041: and acquiring a task corresponding to the interactive element, and determining the type of the task corresponding to the interactive element as the type of the interactive element.
Specifically, the interactive element is determined based on the task and the parameter involved in the interactive process, so that the task corresponding to the interactive element is the task for determining the interactive element, the task corresponding to the interactive element has a type, and the type of the interactive element is the type of the corresponding task. For example, if the M interactive element is determined based on the M task and the n parameter, the task corresponding to the M interactive element is the M task, and the type corresponding to the M interactive element is the type corresponding to the M task.
In one embodiment, the obtaining of the ergonomic requirement and the weight value corresponding to each interactive element includes:
s1061: obtaining human-machine work efficiency requirements and weight values corresponding to each interactive element through external input; or when receiving input information which is input from outside and comprises the human-machine work efficiency requirements and the weight values corresponding to the interactive elements, updating and replacing the existing human-machine work efficiency requirements and the weight values corresponding to the interactive elements with the input information.
Specifically, the ergonomic requirement and the weight value corresponding to each interactive element can be directly determined in an external input mode. Or when the human-machine work efficiency requirements and the weight values corresponding to the interactive elements are stored in advance, and the externally input information including the human-machine work efficiency requirements and the weight values corresponding to the interactive elements is received, the priority of the externally input information is higher, the existing human-machine work efficiency requirements and the weight values corresponding to the interactive elements need to be updated and replaced by the input information, and then when the human-machine work efficiency requirements and the weight values corresponding to the interactive elements are obtained, the obtained information is the input information.
In one embodiment, the obtaining of the human-machine ergonomics evaluation result for each type of condition based on whether the task process of the sample device meets the human-machine ergonomics requirement corresponding to each interactive element and the weight value corresponding to each interactive element includes:
s1081: and if the task process meets the human-computer work efficiency requirement corresponding to the interactive element, judging that the evaluation coefficient corresponding to the interactive element is a first preset value.
S1082: and if the task process does not meet the human-computer work efficiency requirement corresponding to the interactive element, judging that the evaluation coefficient corresponding to the interactive element is a second preset value.
S1083: and obtaining an evaluation value corresponding to each interactive element according to the evaluation coefficient and the weight value corresponding to each interactive element, and accumulating the evaluation values corresponding to each interactive element of the same type to obtain a human-machine work efficiency evaluation result of the corresponding type.
Specifically, the human-machine ergonomics evaluation result is represented by a score, and the quality of the human-machine ergonomics is represented by the grade. Illustratively, assuming that the total score is 100, the interactive elements of X type include X1, X2, and X3, when the task process satisfies the ergonomic requirement corresponding to the interactive element, the evaluation coefficient corresponding to the interactive element is 1, when the task process does not satisfy the ergonomic requirement corresponding to the interactive element, the evaluation coefficient corresponding to the interactive element is 0, the evaluation coefficient and the weighted value corresponding to the X1 interactive element are 1 and 0.2, respectively, the evaluation coefficient and the weighted value corresponding to the X2 interactive element are 1 and 0.5, respectively, and the evaluation coefficient and the weighted value corresponding to the X3 interactive element are 0 and 0.3, respectively, then the ergonomic evaluation result corresponding to X type is 70 (100X 1X 0.2+ 100X 1 0.5X 100X 0.3 =70).
In one embodiment, the ergonomic assessment method further comprises:
s110: and determining the weight value of each type of condition according to the attribute of the sample equipment, and obtaining the comprehensive evaluation result of the sample equipment based on the human-machine ergonomics evaluation result of each type of condition and the weight value of each type of condition.
Specifically, the weight value of each type of condition is determined according to the use purpose of the sample device, taking the transport device as an example, the transport device has three task types of load capacity, safety and driving speed, if the transport device considers the transport capacity firstly, then the transport safety secondly and finally the transport efficiency, the weight of the load capacity is the highest, and the weight of the safety secondly and the transport efficiency is the lowest. And determining the weight value of each type of condition according to the attribute of the sample equipment, so that the finally determined comprehensive evaluation result has pertinence and higher referential performance.
