Device and method for detecting human reaction time

technical field

The invention belongs to the technical field of detection, and in particular relates to a detection device and a method for rapidly detecting the reaction time of a human body.

Background technique

The human body reaction time detection method is a method for detecting the reaction time of the human body to external stimulation signals (including acoustic stimulation signals, photoelectric stimulation signals, tactile stimulation signals and taste stimulation signals, etc.). By detecting the reaction time of the human body to external stimulus signals, the response sensitivity of the subject can be obtained, so as to make a judgment on the sensitivity of the subject.

After searching the literature of the prior art, it was found that the patent 200710126538.7 invented a reaction speed measuring ruler. By measuring the position where the subject grabs the reaction speed test ruler, the reaction time of the subject can be read. The test method is simple. , but has the disadvantage of low test accuracy. Since the position where the subject grabs the test ruler cannot be accurately obtained during the test, it is difficult to accurately measure the test time. Patent 200510032972.X invented a human body comprehensive reaction time test device and method, which can comprehensively detect the reaction time of the hands and feet of the human body, while using a computer controller and an independent test terminal, which can store and display the test time. However, this method mainly has the following disadvantages: (1) the setting and detection of "preemption" is not achieved, that is, the subject may trigger the switch before the external stimulus signal is generated, resulting in inaccurate actual test time; (2) it cannot Changing the time interval of random generation of external stimulation signals, the time interval of random generation of external stimulation signals required by different subjects and different test situations will be different in the actual test.

Contents of the invention

The object of the present invention is to propose a detection device and method for accurate and effective human body reaction time in view of the deficiencies in the prior art. The detection method mainly includes the following key points: (1) Reasonably and effectively start the external stimulus signal and accurately and effectively determine the initial timing moment of the reaction time; (2) Selection of the termination signal trigger device and high-speed and accurate acquisition of the termination signal trigger device (3) Process, analyze and store the test results reasonably.

The technical scheme adopted in the present invention is:

For a single measurement, the control strategy of the human body reaction time detection method involved in the present invention comprises the following steps:

1001: Initialize the detection device, set parameters, and start detection. Initialize the detection device and initialize the parameters; turn off all external stimulus signal generating devices; confirm that there is no trigger termination signal trigger device; set the parameter data T1 and T2 of the start time range [T1, T2], the detection termination time T3, and the parameter requirements T3 >T2>T1>0; set the signal type of the external stimulation signal generator, which is one of many signals such as acoustic stimulation signal, photoelectric stimulation signal, tactile stimulation signal and gustatory stimulation signal, or a combination of multiple signals; in the interval A random number Ts is generated in [T1, T2], and Ts is the moment when the external stimulus signal is generated. Set an interrupt, start the external stimulus signal generating device at Ts time to generate an external stimulus signal; set to generate an interrupt in the data acquisition device when the termination signal trigger device is triggered. After the parameter setting and initialization are completed, the tester will be prompted that the initialization is complete and the test can be started. The subject was prompted to start the human reaction time test after actuating the "Start" button.

1002: The high-speed scan connection termination signal of the data acquisition device triggers the input port of the device.

1003: Compare the relationship between the running time of the current test system and the time Ts when the external stimulus signal is generated, if the running time of the current test system is greater than or equal to the time Ts when the external stimulus signal is generated, then perform step 1004; if the running time of the current test system is less than the time Ts when the external stimulus signal is generated Ts, judging whether the termination signal triggering device is triggered, if the termination signal triggering device is triggered, then jump to step 1006; if the termination signal triggering device is not triggered, then jump to step 1002.

1004: The high-speed scanning connection termination signal of the data acquisition device triggers the input port of the device.

1005: Compare the relationship between the current test system running time and T3, if the current test system running time is greater than or equal to T3, then execute step 1006; if the current test system running time is less than T3, judge whether to trigger the termination signal trigger device, if the termination signal is triggered device, skip to step 1007; if no trigger termination signal triggers the device, skip to step 1004.

1006: End this test, display a detection error, and issue an alarm.

1007: Stop the detection, get the detection time, prompt the end of the test, store and process the data.

If a small data acquisition device (such as a single-chip microcomputer) is selected, it is installed inside the human body reaction time detection instrument; a high-speed data acquisition card installed on a personal computer or a NI (National Instruments, National Instruments, USA) with high-speed data acquisition function can also be selected for use. Co., Ltd.) data acquisition equipment such as Compact IO or PLC (Programmable Logic Controller, programmable controller), and connect the detected digital signal to the human body reaction time detection instrument.

The accessory device includes a start button, a reset button, a stop button, a test signal source (sound signal, light signal or a combination of their signals) selection button, a test times selection button and a display information switching button, a reaction time display device, "Foul" alarm device and auxiliary devices such as detection end indication signal; the button adopts a mechanical switch button, through which the corresponding operation is completed; the reaction time display device is used to display test results and prompt information; the "foul" alarm device is used It is used to indicate the alarm signal; the detection end indication signal is used to indicate the end of the test.

A method for detecting the reaction time of a human body using the above-mentioned device, comprising the steps of:

Step (1): Initialize the detection device: press the reset button to initialize the detection device and initialize the parameters; turn off all external stimulus signal generating devices; confirm that the termination signal trigger device is not triggered;

Step (2); set parameters: set the parameter data T1 and T2 of the start time range [T1, T2], detect the termination time T3, and parameter requirements T3>T2>T1>0; set the external stimulus signal by testing the signal source selection button The signal type of the generating device is one of many signals such as acoustic stimulation signal, photoelectric stimulation signal, tactile stimulation signal and taste stimulation signal or a combination of multiple signals; random number Ts is generated in the interval [T1, T2], Ts is the moment when the external stimulus signal is generated. Set the number of times this test needs to be tested through the number of tests selection button;

Step (3): start detection: set to start the external stimulus signal generating device at Ts time to generate an external stimulus signal; set to generate an interruption in the data acquisition device when the triggering device of the termination signal is triggered. After the parameter setting and initialization are completed, the reaction time display device prompts the subject to complete the initialization, and the test can be started.

Step (4): After the subject presses the start button, the subject starts to respond to the external stimulus signal, and triggers the termination signal triggering device. If the termination signal triggering device is triggered before the external stimulation signal is generated, it is considered that the subject has "fouled", and the "foul" alarm device prompts the subject to "foul"; if the termination signal triggering device is triggered after the external stimulation signal is generated, the subject Moment is the trigger time of the subject;

The present invention has following beneficial effect:

(1) The present invention can set the start time range [T1, T2] of the external stimulation signal, and the detection end time T3 (T3>T2>T1>0), for example, the setting range is [10s, 60s], and the detection end time is 300s. After starting the test, the detection device randomly starts the external stimulation signal within 10s to 60s, and stops the detection when the detection time exceeds 300s, which can avoid the following problems:

A) By delaying the external stimulus signal, the subject has a certain time buffer after receiving the test start signal.

B) Since different test subjects and different test situations require different time intervals for random generation of external stimulus signals, the test has greater flexibility by setting the test interval.

C) By randomly generating signals within the start-up time range [T1, T2] of the external stimulus signal, the signal generation can be made random, so as to prevent the subject from becoming familiar with the test device after many tests and reduce the test accuracy .

D) Since the reaction time of the human body has a range, through the setting of the detection termination time T3, when the detection termination time T3 is exceeded, the test will be automatically stopped and an alarm signal will be sent, so that the test can be performed when the subject is not within the detection time. Stop the test when reacting.

(2) The present invention performs "foul" treatment on the subject. If the external stimulus signal has not yet been generated, but the subject has triggered the termination signal triggering device, the subject is deemed to have "fouled", the detection is set to be invalid, and an alarm signal is issued at the same time. By "fouling" the subject, the subject can be prevented from triggering the termination signal triggering device before the external stimulus signal is generated, so that the test result is wrong.

(3) The present invention adopts the switching value signal sensor to the termination signal triggering device, selects this type of sensor to avoid the phenomenon that the subject's response time is delayed when the mechanical switch is toggled, and simultaneously the triggering of the mechanical switch requires the subject to be aware of the mechanical switch. The mechanical switch exerts a certain amount of force. For subjects with different strengths, there will be different delays when triggering the mechanical switch. It is impossible to accurately record the trigger time of the operator, resulting in errors in test data. The present invention adopts a high-speed signal acquisition device for the acquisition of the termination signal. High-speed data acquisition card can be selected, and data acquisition equipment such as Compact IO, single-chip microcomputer or PLC (Programmable Logic Controller, programmable logic controller) of NI (National Instruments, National Instruments Co., Ltd.) with high-speed data acquisition function can also be selected for use. These high-speed signal acquisition devices can accurately collect the output signal of the termination signal trigger device.
