针对传统的数码分段开关无法设定其控制程序来满足其个性化设置的缺陷。提出了一种通过单片机控制多路开关的状态,并能记忆最后一次开关组合状态的新方法。结果表明,该电路无需采用传统的CMOS电路组成,功能可自主设定,电路简单,成本与传统的数码分段开关相当,能满足地面和矿井下环境的使用。该技术已获国家专利授权。
Aiming at the defect that the traditional digital segment switch can not set its control program to meet its personalized settings. A new method of controlling the state of the multiplexer by a singlechip and memorizing the last switch combination state is proposed. The results show that this circuit does not need to use the traditional CMOS circuit, the function can be set by itself, the circuit is simple, the cost is equivalent to that of the traditional digital segment switch, and it can meet the ground and mine environment. The technology has been the national patent license.
