Detailed Description

The utility model provides an unmanned on duty's visual detection system can carry out visual detection towards masses, and not only the result is accurate, and convenient operation can alleviate medical staff's the amount of labour moreover. The invention is described in detail below with reference to the drawings and the detailed description.

As shown in fig. 1 and 2, the utility model provides a pair of unmanned vision test system is including the visual detection screen 10 and the result confirmation device 20 that are used for random display visual detection sighting target, and the visual detection screen 10 passes through wireless network and confirms the device 20 communication with the result.

The result confirmation device 20 is provided with: a visual target receiving device 21, a direction acquiring device 22, a result acquiring device 23 and a bar code scanning device 25.

The visual acuity test screen 10 randomly generates a visual acuity test optotype, and simultaneously sends the first direction of the optotype to the optotype receiving device 21 through the wireless network, so that the optotype receiving device 21 obtains the first optotype direction.

The direction acquiring device 22 is provided with an up button, a down button, a left button, a right button and a confirmation button, the tester selects the corresponding up button, the down button, the left button and the right button according to the opening direction of the visual target 'E' appearing on the vision detecting screen 10, and confirms, and then the direction acquiring device 22 can acquire the second visual target direction judged by the tester according to the selection of the tester.

According to the comparison result between the first visual target direction and the second visual target direction, the result obtaining device 23 can determine whether the second visual target direction given by the tester is correct, thereby obtaining the vision detection result.

The utility model discloses in, the result is confirmed device 20 and can be realized by adopting handheld panel computer. The handheld tablet computer is provided with a touch screen, and the selection of the upper button, the lower button, the left button and the right button is determined by the sliding direction of a tester on the touch screen of the handheld tablet computer.
