Description

Technical Field

[0001] The present invention relates to the technical field of human reaction time testing, in particular to a set of devices for testing human reaction time and a testing method thereof. Background Art

[0002] Currently, for the human reaction time testing method, when a stimulus signal appears (such as a light turning on), the tester presses a stopwatch (or other timer) to start timing. When the subject receives the stimulus signal, the subject makes a specified action. After the tester sees the action, the timing ends. Due to the timing device being manipulated by others, this testing method has inevitable testing errors and the data is not accurate enough.

[0003] To solve the above technical problems, the inventor of the present invention has designed a set of devices for testing human reaction time and a testing method thereof, and this case is thus produced. Summary of the Invention

[0004] To solve the above problems, the technical solution of the present invention is as follows:

[0005] A set of devices for testing human reaction time includes an external stimulus device, a signal collection device, and a central signal processor. The external stimulus device includes a stimulus signal releaser and a first signal induction control device disposed on the periphery of the stimulus signal releaser for sensing the time when the stimulus signal releaser releases a signal source. The signal collection device further includes a second signal induction control device fixed to the human execution part for automatically collecting the time of change of human nerve signals. The first signal induction control device and the second signal induction control device both transmit the time of the induction signal to the central signal processor.

[0006] Further set as: The first signal induction control device includes a first signal induction controller for sensing changes in external stimulus signals, and a first fixator for fixing the first signal induction controller on the periphery of the stimulus signal releaser.

[0007] Further set as: The second signal induction control device includes a second signal induction controller for sensing human signals, and a second fixator for stably fixing the second signal induction controller to the human execution part.

[0008] Further set as: The external stimulus device is provided with a switch for controlling whether the stimulus signal releaser releases a signal.

[0009] Further set as: The stimulus signal released by the stimulus signal releaser is light or sound.

[0010] Further set as: The stimulus signal releaser is a percussion rod, and the percussion rod releases different magnitudes of acting forces in multiple dimensions.

[0011] It is further set that: the external stimulation device further includes an adjustment part for adjusting the height of the stimulation signal releaser.

[0012] A method for testing human reaction time includes the following steps:

[0013] a) Activate the switch, and the stimulation signal releaser releases a stimulation signal;

[0014] b) The first signal induction controller senses the stimulation signal and transmits the time when the stimulation signal is sensed to the central signal processor; at the same time, the subject, in a resting state, receives the stimulation of the stimulation signal releaser and performs a specified reaction action after receiving the stimulation. The second signal induction controller senses the change in the electrical signal of the test part and transmits the time when the change in the electrical signal is sensed to the central signal processor;

[0015] c) The central signal processor receives the signal time between the first signal induction controller and the second signal induction controller, and the time difference between the two is the reaction time required for the tester to perform the test action.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By setting an external stimulation device, a signal collection device, and a central signal processor, the stimulation signal releaser of the external stimulation device releases a stimulation signal to prompt the subject to complete a specified action. At the same time, the first signal induction control device collects the release time of the stimulation signal. By placing the second signal induction control device at the human execution part, the change of the human electrical signal of the execution part over time after the human body receives the stimulation signal is collected. The signal change conditions collected by the first signal induction control device and the second signal induction control device are transmitted to the central signal processor, and through the central signal processor, information comparison and analysis are completed, and the human reaction time is calculated. Directly testing the human reaction time by a machine can effectively avoid errors caused by manual operation, and directly test the human myoelectric response. The measured data is closer to the true human reaction time, the data is accurate, and the error is extremely small;

[0018] 2. The height of the adjustment part of the external stimulation device can be adjusted arbitrarily according to requirements, which can meet the requirements for different heights of the stimulation signal releaser due to different heights of the testers during the test, and the test range is wider;

[0019] 3. The stimulation signal releaser in the external stimulation device can release various types of signal sources, which can meet more test requirements;

[0020] 4. When the stimulation signal releaser is connected to a tapping rod and acts on the knee of the human execution part, the data of the human passive reaction time can be measured, and the data is accurate and the error is extremely small. Description of the Drawings

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Embodiment 1 is as follows:

[0035] As Figures 1 to 4 shown, a test equipment group for testing the reaction time of the human body includes an external stimulus device 2, a signal collection device 3, and a central signal processor (not shown in the figure).

[0036] The external stimulation device 2 includes a stimulation signal releaser 21, a switch 211 for controlling whether the stimulation signal releaser 21 releases a signal, an adjustment unit 23 for adjusting the height of the stimulation signal releaser 21, and a first signal induction control device 22 disposed on the periphery of the stimulation signal releaser 21 for sensing the time when the stimulation signal releaser 21 releases a signal source. The stimulation signal released by the stimulation signal releaser 21 is light or sound.

[0037] The first signal induction control device 22 includes a first signal induction controller 221 for sensing changes in external stimulation signals, and a first fixator 222 for fixing the first signal induction controller 221 on the periphery of the stimulation signal releaser 21.

[0038] The height of the adjustment unit 23 of the external stimulation device 2 can be adjusted arbitrarily according to requirements, which can meet the requirements for different heights of the stimulation signal releaser 21 due to different heights of the test subjects during the test. The test range is wider. The stimulation signal releaser 21 can release various types of signal sources, which can meet more test requirements.

[0039] The signal collection device 3 further includes a second signal induction control device 31 fixed to the human body execution part and automatically collecting the time of change of human nerve signals. Both the first signal induction control device 22 and the second signal induction control device 31 transmit the time of the induction signals to the central signal processor.

[0040] The second signal induction control device 31 includes a second signal induction controller 311 for sensing human body signals, and a second fixator 312 for stably fixing the second signal induction controller 311 to the human body execution part.

[0041] The stimulation signal releaser 21 releases a stimulation signal to prompt the subject to complete a specified action. At the same time, the first signal induction control device 22 collects the release time of the stimulation signal. The second signal induction control device 31 collects the change of the human body electrical signal of the human body receiving execution part over time. The signal change conditions collected by the first signal induction control device 22 and the second signal induction control device 31 are transmitted to the central signal processor. Through the central signal processor, information comparison and analysis are completed, and the human reaction time is calculated. Directly testing the human reaction time by a machine can effectively avoid errors caused by manual operation, and directly test the human electromyogram reaction. The measured data is closer to the true reaction time of the human body, the data is accurate, and the error is extremely small.

[0042] The working steps of this embodiment:

[0043] a) Start the switch 211, and the stimulation signal releaser 21 releases a stimulation signal;

[0044] b) The first signal sensing controller 221 senses the stimulation signal and transmits the time when the stimulation signal is sensed to the central signal processor; at the same time, the subject is in a resting state, receives stimulation from the stimulation signal releaser 21, and performs a test-specified reaction action after receiving the stimulation, and the second signal sensing controller 311 senses the change of the electrical signal at the test site and transmits the time when the change of the electrical signal is sensed to the central signal processor;

[0045] c) The time difference between the signal received by the central signal processor between the first signal sensing controller 221 and the second signal sensing controller 311 is the reaction time required by the tester to perform the test action.

[0046] d) The subject is tested multiple times using the same method, the maximum and minimum values ​​of the test data are removed, and the remaining numbers are averaged, which is the reaction time of the subject to the light / sound signal in this test.

[0047] Example 2 is as follows:

[0048] The difference between it and Example 1 is that:

[0049] Reference Figure 5 , the stimulation signal releaser 21 is connected to the knocking rod 24, and the magnitude of the force is adjusted by adjusting the weight and action angle of the knocking rod 24 to meet the test requirements. And the first signal sensing control device 22 can be fixed to the knocking rod 24 to act on the human body. When the knocking rod 24 knocks on the human knee, the first signal sensing control device 22 begins to collect and record the change of the force over time, and the second signal sensor control device 31 fixed on the muscle group near the human knee also begins to record the change of human electromyography. Since the execution part is the knee, the human body automatically completes the knee jerk reaction without specifying the execution part to complete the specified action. The signals collected by the first signal sensing control device 22 and the second signal sensing control device 31 are transmitted to the central signal processor for signal recording and analysis to calculate the human body reaction time. Since the force acting on the knocking part is the human knee, it is an unconditioned reflex of the human body, so the human body reaction time test equipment group can accurately measure the time of the human body's passive reaction.

[0050] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
