Embodiment Construction

[0016] The present invention is further described below by way of embodiment and accompanying drawing.

[0017] The referee electronic circuit involved in the present invention consists of 7 parts:

[0018] Figure 1 is the power interface, which is connected or disconnected with the battery through a switch to control whether to supply power to the circuit or not. The positive pole of the 3V lithium battery is connected to the VCC signal of the circuit through the pads J2, J22, J222, J2222 of the socket, the negative pole is connected to the J5 pad, S1 is a button switch, one end is connected to the J5 pad, and the other end is connected to the circuit ground Signal connection, when the button is pressed, the positive and negative poles of the lithium battery are connected to the VCC and ground of the circuit respectively, and power is supplied to the circuit, and it is disconnected when the button is not pressed, so as to reduce power consumption;

Abstract

The electronic judging device for military chess is powered with 3V metal lithium battery. Each of the chess men is mounted with resistor of different resistance, and when it is set in designated position, some circuit is connected to produce two voltage dividing signals depending on the chess man. The electronic judging device is provided with upper and lower voltage limit circuit to eliminate the effects of varying battery voltage and circuit element error. One 8-bit MCU monochip computer is used to generate ramp signal, and the ramp signal is compared with the 4 input signals in the 4 comparators of LM339 chip to output 4 pulse signals. The widths of the 4 pulse signals are measured with the monochip computer to obtain 4 values and the 4 values are compared to obtain the relative rank of the two chess men. The relative rank is displayed with LED. The present invention is used to replace judger.

Description

technical field [0001] The invention belongs to the technical field of chess competitions, in particular to an electronic judging device for military chess. Background technique [0002] Online surveys show that there are many Chinese chess, military chess, and Go players. Chess and Go can be played by two players. Military chess is mainly played in dark chess, which pays attention to marching and formation. When two or four players play games, other people are required to act as referees. The referee is boring, which affects the fun that military chess brings to people. [0003] The present invention is an electronic judging device for military chess. When in use, place two chess pieces of both sides on the device at a designated position, press the two chess pieces on the table with a little force, and the LED lights on both sides of the chess pieces on the device indicate whether the two chess pieces win or lose. A total of three situations occur: Simultaneously illumin...
