Problems solved by technology

This method solves the shortcomings of single detection index, long detection fatigue time and poor objectivity when the traditional flash fusion frequency meter detects fatigue, and introduces reaction time as another index of fatigue detection, avoiding the measurement deviation caused by single index

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] It is suitable for the environment of rapid detection of fatigue, such as the detection of driver fatigue.

[0017] Since the background light seriously affects the detection of the critical flash fusion frequency, the goggle structure is selected to ensure the dark environment, and the optical system is used inside the goggle to image the target at a viewing distance of 250mm. The whole test device consists of an eye mask and an input handle. After the test is completed, the test result can be output to the display digital tube of the test device, and the test data and test results can also be transmitted to the mobile APP / server via Bluetooth for storage and backup.

[0018] A method for quickly and conveniently detecting job fatigue, the method comprising the following steps:

[0019] Step 1: Select as figure 1 The four direction a...

Abstract

The invention discloses a method for rapidly and conveniently detecting work fatigue, and belongs to the field of detecting the work fatigue, aiming at overcoming the shortcomings of a conventional detection method which has a single indicator and a long detection duration and is in lack of objectivity. A plurality of sighting marks are adopted for detection; the frequency of each sighting mark drops from a high frequency to a low frequency and then increases to the high frequency, with a same frequency changing rate, different times of beginning to change and random orders of beginning to change. In a detection process, an order, that each sighting mark begins to flicker / not flicker, pointed by a detected object, a critical flicker fusion frequency and a response time are recorded. It can judge whether current data are valid or not in accordance with the sighting mark order pointed by the detected object and can judge the fatigue of the detected object in accordance with the critical flicker fusion frequency and the response time. According to the method disclosed by the invention, the objectivity and the accuracy of acquiring visual neurobehavioral function data can be improved and the learning effect of the detected object can be reduced. Detected data can be conveyed to and stored in a database, so as to further analyze visual neurobehavioral functions; therefore, the fatigue status of the detected object can be analyzed from both transverse evaluation and longitudinal evaluation.

Description

technical field [0001] The invention belongs to the field of operation fatigue detection and is a method for quickly and conveniently detecting operation fatigue. Background technique [0002] Reaction time is the interval time between receiving a stimulus and producing a response, and it is closely related to the functional status of the cerebral cortex. When fatigued, the function of the cerebral cortex declines, and the conditioned reflex activity is also affected, which is manifested as prolonged reaction time and increased reaction errors. Studies have shown that in the mental fatigue of continuous workload, the reaction time increases with the workload time, and the difference is statistically significant. [0003] When a light stimulus with a low intermittent frequency acts on the human eye, it will produce a bright and dark flickering feeling. When the number of flashes per second increases to a certain level, the human eye will no longer feel the flash and feel it ...
