Abstract
The utility model discloses a vision tester and belongs to the vision testing field. The vision tester comprises a power module for supplying power, an industrial control main board, a liquid crystal displayer, a remote control receiver and a remote control emitter. The industrial control main board is connected with the liquid crystal displayer through a low voltage differential signaling (LVDS) line. The remote control receiver is connected with the industrial control main board through a serial port line and sends signals sent by the remote control emitter to the industrial control main board in a serial port communication mode. The industrial control main board displays E-shaped signs of different directions and sizes on the liquid crystal displayer according to a procedure, sitting at a remote place, a tested person sees the E-shaped signs and then answers the direction of the E-shaped signs through the remote control emitter, a vision value of the tested person is tested by the industrial control main board after a plurality of tests, and then a function of automatically testing vision is achieved.
Description
Technical field
This utility model relates to a kind of viseon tester, belongs to the eyesight measurement field.
Background technology
In hospital, the doctor usually tests eyesight to the person under inspection with visual acuity chart or sight list box.The doctor need be sitting in by the visual acuity chart, that point to different sizes with a sharp shaped material and direction " E " symbol, allow the person under inspection answer by the mode of gesticulating direction with hands then, the doctor provides measurement result according to patient's situation of answering again, and this result is easy to be subjected to anthropic factor to influence.
The utility model content
Technical problem to be solved in the utility model is the defective that exists at the existing method of measuring vision, proposes a kind of simple and practically, measures viseon tester accurately.
This utility model adopts following technical scheme for solving above technical problem:
A kind of viseon tester comprises the power module, industrial control mainboard, liquid crystal display, receiver of remote-control sytem and the remote control transmitter that are used to power.Described industrial control mainboard is connected by the LVDS line with liquid crystal display; Described receiver of remote-control sytem is connected by Serial Port Line with industrial control mainboard, and the signal that remote control transmitter is sent sends to industrial control mainboard by the mode of serial communication.
As further prioritization scheme of the present utility model, also comprise an on and off switch that is connected with power module, described on and off switch is realized the open and close of tester by the break-make of control power module.
As further prioritization scheme of the present utility model, also comprise an amplifier and speaker; Described speaker is connected with industrial control mainboard by amplifier.
This utility model adopts above technical scheme, compared with prior art has following technique effect:
This utility model adopts industrial control mainboard as main control module, and system structure is simple, and function can be upgraded as required.
This utility model demonstrates " E " type symbol automatically by system's computing, and draws the vision value according to person under inspection's situation of answering, and saves manpower, and can not influence measurement result because of anthropic factor.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done introduction in further detail:
Structured flowchart of the present utility model comprises the power module, industrial control mainboard, liquid crystal display, receiver of remote-control sytem, remote control transmitter, on and off switch, amplifier and the speaker that are used to power as shown in Figure 1.Described on and off switch links to each other with power module, the break-make of control power module, and power module is connected to industrial control mainboard, powers for whole device.Described industrial control mainboard is connected by the LVDS line with liquid crystal display, shows by LVDS signal controlling liquid crystal display.Described receiver of remote-control sytem is connected by Serial Port Line with industrial control mainboard, and the signal that remote control transmitter is sent sends to industrial control mainboard by the mode of serial communication.Described speaker is connected with industrial control mainboard by amplifier, and industrial control mainboard drives speaker by amplifier and realizes sound prompt function.
Work process of the present utility model is as follows, and the user turns on the power switch energized, enters holding state after the tester initialization.Person under inspection's hand-held remote control emitter is sitting in the predetermined distance place apart from liquid crystal display, the person under inspection sends test command by remote control transmitter, the control liquid crystal display showed first " E " type symbol after industrial control mainboard received test command by receiver of remote-control sytem, and drive speaker prompting person under inspection by amplifier and answer, symbol direction on the display that the person under inspection will see sends to industrial control mainboard by remote control transmitter, industrial control mainboard shows next " E " type symbol according to person under inspection's the situation of answering by control liquid crystal display behind the sequential operation, driving speaker prompting person under inspection by amplifier again answers, so behind the circulation several times, industrial control mainboard draws person under inspection's vision value according to person under inspection's the situation of answering after by sequential operation, be presented on the liquid crystal display, and carry out the voice report by speaker.
