The Design of Digital Display Gateball Scoring System
Abstract: This article designs a gateball scoring system which primarily consists of integrated chips 74LS148, 74LS194 and 74LS190. It explicitly introduces the design project and the principle. The team-member-score-display system consists of one piece of encoder 74LS148, two pieces of shift register 74LS194 and five light emitter diode. The transmission circuit of the team’s total score signal is composed of a piece of the 3×3 input AND gate 4073. The team’s total-score-display circuit is composed of one piece of encoder 74LS148, two pieces of decimal counter 74LS190, two pieces of decoders 74LS48 and two pieces of glow discharge nixie tube BS201. The system works reliably, operates easily, and it has low cost and great application prospect.
Key words: gateball; scoring system; team member score; entire team total score
