Modular electronic vision tester

Abstract

The invention provides a modularized electronic eyesight detector. The modularized electronic eyesight detector comprises a CPU chip, an eyesight detection circuit module, a mounting housing and expansion interfaces. The CPU chip and the eyesight detection circuit module are integrated in a detection function module, the detection function module is arranged in the mounting housing, the mounting housing is provided with a plurality of the expansion interfaces (4), and the detection function module is connected with the external equipment through the plurality of the expansion interfaces (4). According to the invention, the CPU chip and the eyesight detection circuit module in the electronic eyesight detector are split off from a conventional display electronic eyesight detector all-in-one machine, the structure of the modularized electronic eyesight detector is simplified, and the modularized electronic eyesight detector can be installed conveniently, and can adapt to various devices with display screens, another multimedia function and a network interconnection function are integrated in the modularized electronic eyesight detector, user' demands can be satisfied better, and the user experience can be improved.

Description

technical field [0001] The invention relates to the field of electronic vision inspection, in particular to a modularized electronic vision inspection instrument. Background technique [0002] At present, the known electronic vision tester equipment is a vision test device that is integrated with a module and a display screen similar to a computer all-in-one machine. Such an electronic vision tester integrates CPU chips, circuit boards and other equipment into the rear cover of the display screen. , Then redesign the shell and make it into an all-in-one machine. This solution has the following disadvantages: [0003] 1. Due to the integration of the display screen, the whole device is bulky and bulky, making it inconvenient to install, transport and carry. [0004] 2. Due to the existence of various connection lines and circuit interfaces between various circuit boards and display screens, data transmission is unreliable; in addition, various display failures will occur on...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the integrated display screen, the whole device is bulky and bulky, making it inconvenient to install, transport and carry

[0004] 2. Due to the existence of various connection lines and circuit interfaces between various circuit boards and display screens, data transmission is unreliable; in addition, various display failures will occur on the display screen itself, resulting in frequent failures of this electronic vision tester. hair, difficult to maintain

[0005] 3. Since the electronic vision tester has chosen a fixed size, it cannot meet the flexible needs of users with various display sizes

[0006] 4. The existing vision tester cannot solve the glare requirements in the vision test well

[0007] 5. Existing visual inspection instruments mostly use traditional analog signals, which cannot output high-definition digital signal inspection pictures

[0008] 6. Due to the performance limitations of the screen and CPU chip of the existing vision tester, it is difficult to play high-definition movies above 1080p smoothly, which makes the vision tester have a single function and cannot meet the needs of audio-visual entertainment

[0009] 7. Unable to access WIFI and wired network, so that it cannot be connected to the network
