Embodiment 1

[0024] Embodiment 1: as figure 1 , which is a block diagram of an intelligent full-automatic speedometer with multi-screen display, which includes a speedometer [1]: the speedometer [1] contains a set of optical path components identical to the original two-field speedometer, 2 Group light source drive, 2 hand keys; the difference is that there are 2 groups of dedicated VGA-format LCD displays that have discarded their own backplane light sources and 2 groups of on / off, Back panel light source with independently controllable brightness. In addition, a PC, a PC monitor, a VGA signal distributor and a control unit mainly composed of a single-chip microcomputer are added to the whole machine [2]. The VGA signal of the PC can be divided into two channels through the dual-output graphics card, one output terminal is connected to the input terminal of the VGA signal distributor, and the other output terminal is connected to the LCD display B; the two-channel output of the VGA signa...

Embodiment 2

[0032] In order to reduce the cost, the LCD display adopts a dedicated video LCD display, that is, a liquid crystal color display in video format. For this reason, this embodiment adds a video conversion unit [3] which is formed by a video converter before the video LCD display. In the video conversion unit [3] are two video converters. A video converter is a device used to convert a VGA signal into a video signal. After the VGA signal is converted by the video converter, the output video format signal is sent to the LCD color display for image display.

[0033] like figure 2 As shown, one output end of the PC is connected to the input end of the VGA signal splitter, the other output end is connected to the input end of the video converter B, and one output end of the VGA signal splitter is connected to the input end of the video converter A The other output end is connected to the PC monitor, the output end of video converter A is connected to video LCD display A, and the...

Abstract

The present invention discloses one kind of fully automatic intelligent tachystoscope with multiple display screens. The scheme is that the fully automatic intelligent tachystoscope includes tachystoscope, PC, signal distributor and control unit. The PC has one output connected with the input of VGA signal distributor and the other output connected to LCD display; the VGA signal distributor has output connected to PC display and LCD display; the control unit has bi-directional port connected with the serial port of PC, input connected to hand key and output connected to the light source driver; the light source driver has output connected to the independent controllable back plate light source; and the LCD display is installed between the light path member and the independent controllable back plate light source. The present invention can switch between various visual information automatically and accurately and may be applied in various psychological test.

Description

technical field [0001] The invention relates to a psychological testing instrument, in particular to a psychological testing instrument for presenting visual stimuli in a short time. Background technique [0002] "Tachometer" is a psychological testing instrument that presents visual stimuli for a short time, and is an important device in psychological science research. It is suitable for studying the process of individual processing of visual information. It can conduct various experiments and tests such as perception, attention, memory, language understanding and thinking. It is widely used in military, sports, public security, education, special industries and industrial management, etc. field of psychological research. Over the years, scholars at home and abroad have conducted a large number of experiments through tachometers and achieved many research results. However, there are still some defects in the traditional tachometer, which have a direct impact on the in-dep...
