Abstract
The utility model relates to an instrument for testing drivers' mental states. A central control circuit (3) of the utility model is mainly composed of a computer, one output port of the computer is connected with the input port of a luster type incitation part (1), and the other output port is connected with the input port of an alarm part (4). The output port of an active feedback part (2) is connected with the input port of the central control part. When the utility model is used, the computer can accurately judge the examined persons' mental state through the reaction of the keystroke of the active feedback part by the examined persons. The utility model has the advantages of simple structure and convenient operation and can test the drivers' mental states at any time, and the driving accidents can be effectively prevented from occurring.
Description
This utility model relates to a kind of instrument that can measure the human body mental status, particularly a kind of detector of measuring driver's mental status.
Driver's the mental status is most important to the traffic safety of automobile, and it is at present very difficult to the detection of driver's mental status, detection only can utilize the EEG(electroencephalography) instrument by measuring electroencephalogram its mental status to be judged as need, detect driver's the mental status with the EEG(electroencephalography) instrument, not only troublesome poeration is wasted time and energy, and needs to be equipped with the medical professional operation, and owing to be subjected to the influence of factors such as individual variation, the judgement of the mental status is also existed difference.
The purpose of this utility model is to provide a kind of driver's mental status detector.It is not only simple in structure, and is easy to operate, and certainty of measurement is higher, and, can in driving, carry out mental status detection, thereby effectively avoid the generation of driving accident the driver.
This utility model is achieved in that by light pattern stimuli circuit, central control circuit, active feedback circuit, warning circuit four parts to be formed.Light pattern stimuli circuit is made up of driving and demonstration two parts circuit, and drive circuit has adopted the integrated package of buffering or power amplification effect, and display circuit is made of active display, and can produce the light stimulation of different mode.Central control circuit mainly is made of computer, its output port connects the input port of light pattern stimuli circuit, another output port is received a crime report and is reported the input port of part, and the output port of active feedback part is connected with the input port of center control section.Active feedback partly is provided with non-locking button, and non-locking button is connected with the computer input port by gate circuit or buffer circuit.During detection, the driver can partly make reflection by active feedback according to the stimulation of different mode, and signal is imported the center control section, is judged by this part, if any reporting to the police by the part of reporting to the police unusually.
In conjunction with the accompanying drawings this utility model is described in detail below by embodiment:
Fig. 1 is this utility model circuit block diagram.
Fig. 2 is this utility model circuit theory diagrams.
In Fig. 1 block diagram, the input port of light pattern stimuli circuit (1) is connected with an output port of center control section (3), another outfan of center control section (3) is connected with the input port of the part (4) of reporting to the police, and the input port of center control section (3) is connected with the outfan of active feedback part (2).

3) can carry out mental status judgement to the detected person in view of the above, as be not in good state, central control circuit will be by buzzer (S
3) give the alarm, as no abnormal, can continue to detect.
The reaction that this utility model has been done button by the detected person, computer can be accurately judges detected person's the mental status, simple in structure, easy to operate, particularly can carry out the mental status to the driver at any time detects, thereby effectively avoided the generation of driving accident, safe driving has been played an important role.
Claims (2)
1, a kind of driver's mental status detector, the input port that it is characterized in that producing the light pattern stimuli circuit (1) that the different mode light stimulates is connected with the output port of the main center control section (3) that is made of computer, another output port of center control section (3) is connected with the input port of the part (4) of reporting to the police, and the input port of center control section (3) is connected with the output port of active feedback part (2).
