Problems solved by technology

But there are some disadvantages in this way of the prior art: 1. The operator needs to interact with the test software, and the test software sends an order and waits for the operator to press the key; 2. The test time is long and the efficiency is low; Need to repeat; 4. The operator may slow down; and others, etc.

Embodiment Construction

[0018] Regarding the features and implementation of the present invention, the preferred embodiments are described in detail below in conjunction with the drawings.

[0019] Please refer to figure 1 , the figure shows the automatic detection system of the notebook computer keyboard interface of the present invention. This system runs in the notebook computer 10, comprises universal serial bus (USB) communication module 16, matrix switch chip 18 (preferred implementation mode can be realized by such as MT8816 chip or other similar switch assembly), switch Device 20 and test software 12. The USB communication module 16 can be a USB communication device of a Cy7c68013 main control chip, which receives the commands of the test software 12 running in the notebook computer 10 through the USB port and converts them into control signals. The command transmitted by the test software 12 to the USB communication module 16 includes the position value of the key to be tested, that is, th...

Abstract

The present invention discloses a system and a method for automatic detecting a keyboard interface of a notebook computer. The method comprises: acquiring a keyboard position corresponding list through scanning a keyboard array of the notebook computer firstly; acquiring a position value of a key to be tested from the keyboard position corresponding list by testing software running in the notebook computer; receiving a testing command sent by the testing software through a general serial bus interface; forming a virtual keyboard matrix by using at least one matrix switch chip so as to control the closing action corresponding to the position of the keyboard in the virtual keyboard matrix according to the testing command; according to the type of the keyboard interface of the notebook computer, switching and outputting a real key position value corresponding to the closing action to the notebook computer; and receiving a real key position value and comparing the received real key position value with the position value of the key to be tested.

Description

technical field [0001] The invention relates to an automatic detection system and a method thereof, in particular to a system and a method for automatically detecting a computer keyboard interface. Background technique [0002] During the manufacturing process of a notebook computer (Notebook Computer), it is usually necessary to test the interfaces of various external accessories on the motherboard, including the keyboard interface. The keyboard of a notebook computer is a matrix structure, which is composed of certain row scanning lines and column scanning lines. Each key is located at a certain cross point in the matrix. Pressing the key causes a connection between a certain row and a certain column in the matrix. . The notebook computer determines the position of the key by sending a scanning signal to the row (column) line in the keyboard interface, and then reads the signal from the column (row) line, and then converts it into a certain key code. The keyboard interfa...
