Embodiment 1
[0022] A pencil case with the functions of answering and judging primary school mathematics questions and simulating questions for examinations. Its composition includes: a pencil case (1) and a cover (2). Correct answer LED (11), wrong answer LED (12), input effective LED (13), button circuit (3), USB interface (5), loudspeaker (10), control circuit board (4) is installed in the interlayer of lid ), the control circuit board includes a microprocessor (15), and the internal storage space of the microprocessor is greater than 4M; the XRD, TXD, P0 port of the microprocessor and the MP3 and speech synthesis output module (16 ) connection, the audio output terminal OUT of the MP3 and speech synthesis output module is connected to the speaker (10) and the socket (14) of the external earphone;
[0023] The P1 and P2 I / O ports of the microprocessor are connected to the button circuit (3), the correct answer LED (11), the wrong answer LED (12), the input valid LED (13), the photocell ...
Embodiment 2
[0026] The above-mentioned method of answering questions and judging questions of the pencil case, and imitating examination questions is divided into 32 fixed language segments and solidified in MP3 and speech synthesis output modules (16), and the output is controlled by a microprocessor; the voice segments include: Use Chinese (or other languages) to output "computation answer judgment question", "self-inspection mode A", "test mode B", "imitation test mode C", "input formula and answer", "ten numbers of 1-0 ", "percentage", "point", "addition", "subtraction", "multiplication", "division", "equal", "greater than", "less than", "bracket", "end of parenthesis", "calculated correctly ", "Calculation Error", "Start", "End", except "Calculation Correct", "Calculation Error" 2 voices need to calculate and compare the input answer with the calculation result of the microprocessor and determine according to the result In addition to the output, the rest of the speech segments are d...
Embodiment 3
[0033] According to the pencil case described in embodiment 1 with the function of answering and judging primary school mathematics questions and imitating questions for examinations, this pencil case includes 3 main functions: 1. The function of automatically judging questions and answers of elementary school four arithmetic operations through keyboard input is calculation Self-inspection mode A; 2. Addition, subtraction, multiplication, division and mixed operations within 3 digits of automatically generated voice questions. Enter the answer through the keyboard, the automatic judgment function is the test mode B; 3. Import the artificially edited voice (MP3 format) of elementary school four arithmetic expressions and application question voice through USB, and the automatic judgment function of the answer through the keyboard is the simulated test mode c.
[0034] When in use, press the corresponding button to enter respectively: "A" keyboard input elementary school four ar...
