[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] The embodiments of the present invention are written in a progressive manner.

[0052] The embodiment of the utility model provides a vision detection device, which mainly solves the technical problem in the prior art that external factors and human subjective judgment affect the accuracy and efficiency of vision detection.

[0053] like Figure 1As shown, a vision detection device includes: a main body 1, an interactive component 2, a voice recognition component 3 and a controller 4;

[0054] The front of the main body 1 is provided with an interactive component 2 and a voice recognition component 3;

[0055] The speech recognition component 3 is arranged on the upper part of the interaction component 2;

[0056] A controller 4 is provided in the main body 1;

[0057] The controller 4 is connected to the interaction component 2 and the speech recognition component 3 respectively;

[0058] A controller 4 is used to set a plurality of sight mark sets formed randomly with different notches facing different sight marks, and to set the interval time for displaying the sight marks;

[0059] Interactive component 2, for responding to the vision detection instruction and displaying each sight mark in the current sight mark set at intervals;

[0060] The speech recognition component 3 is used to obtain the speech information of the corresponding sight mark about the direction of the gap during the interval of sight mark display;

[0061] The controller 4 is also used to implement vision detection based on the voice information and each sight mark in the current sight mark set.

[0062] During actual use, before conducting a vision test, a set of sight marks formed by randomly forming a number of sight marks with different notch directions is set in the controller inside the main body. The commonly used sight mark is the letter "E", that is, a number of "E" letters with different notch directions are randomly formed into a sight mark set, and the display interval time of two adjacent sight marks is set at the same time; during the vision test, each sight mark in the current sight mark set is displayed in sequence by the interactive component according to the sight mark display interval time; within the sight mark display interval time period, the voice information of the corresponding sight mark about the notch direction is detected and obtained by the voice recognition component; the controller records whether the voice information hits the notch direction of each sight mark in the current sight mark set, so as to realize vision testing.

[0063] In this embodiment, the vision test requires that the time for identifying the direction of the notch of the sight mark "E" each time should not exceed 5 seconds, so the interval between the display of two adjacent sight marks is set to 5 seconds.

[0064] Assuming that the gap direction of the first sight mark "E" displayed is upward, then in the interval time period between the first sight mark and the second sight mark "E", the voice information about the gap direction of the first sight mark of the vision test subject is collected through the voice recognition component, specifically, the keywords containing the gap direction, such as "up", "down", "left" and "right", and the gap direction and voice information of the first sight mark are recorded through the controller. If the voice information contains the keyword "up", it is determined that the first sight mark is hit;

[0065] Assuming that the gap direction of the second sight mark "E" is downward, in the interval time between the second sight mark and the third sight mark "E", the voice information about the gap direction of the second sight mark of the visual inspection subject is collected by the voice recognition component, and the direction of the second sight mark and the voice information are recorded by the controller. If the keyword containing the gap direction is not collected or the collected voice information does not contain the keyword "down", it is determined that the second sight mark is not hit;

[0066] By analogy, during the entire vision test process, the vision of the vision test subject is determined through the hit results of the current sight mark set recorded by the controller;

[0067] The controller can be specifically a PLC, and corresponding functional modules can be set in the PLC to realize the functions of judgment, statistics and calculation in the above vision detection process;

After receiving the distance detection instruction, the distance detection component collects the current vision detection distance of the vision detection object;

[0074] In this embodiment, the distance detection component can specifically use a combination of a camera and a distance sensor, and use the camera to determine whether the vision detection object is in place, and use the distance sensor to determine the current position of the vision detection object, that is, the current vision detection distance.
