Equipment and method for rapidly and conveniently detecting operation fatigue

Abstract

The invention relates to equipment and method for rapidly and conveniently detecting operation fatigue and belongs to the field of detection of operation fatigue. The equipment comprises an eye shield, a camera bellows, an operation device, an optical system and a sighting target display control system; the optical system and the sighting target display control system are mounted inside the camera bellows; the operation device is connected with the sighting target display control system; a detected person observes the inside of the camera bellows by the eye shield, sees sighting targets with different frequencies, which are output by the sighting target display control system, by the optical system and responds to the identified sighting targets by the operation device, and analysis detection software in the sighting target display control system receives a signal sent out by the operation device, calculates out and displaying frequencies of sighting targets displayed by the sighting target display control system in a next detection period, analyzes fatigue of the detected person after detection is finished, and sends a final detection result to external storage equipment. According to the equipment and method disclosed by the invention, objectivity and accuracy of acquiring optic nerve behavior function data are improved. In an actual application scene, detection parameters are set according to requirements of accuracy and detection duration.

Description

technical field [0001] The invention belongs to the field of work fatigue detection, and is a device and method for quickly and conveniently detecting work 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 i...

Problems solved by technology

[0005] In order to solve the problems existing in the prior art, the present invention provides a device and method for quickly and conveniently detecting job fatigue, which solves the problems of single detection index, long fatigue detection time and poor objectivity when traditional flash fusion frequency meter detects fatigue. Disadvantages, the introduction of reaction time as another indicator of fatigue detection avoids the detection bias caused by a single indicator
