【摘要】 由于低压电器对单片机应用系统有严重的干扰,困扰了单片机的应用。通过智能式电能表的实践,探讨出低压电器干扰单片机的机理:感性元件的电磁干扰,触头的火花干扰以及单片机的电源遭受污染后导致单片机应用系统不能正常工作。提出相应的抗干扰对策:硬件抗干扰措施、软件抗干扰措施以及工艺方面抗干扰措施。通过智能式电能表的实践证明上述抗干扰的措施是行之有效的。更多还原

【Abstract】 Singlechip application was jammed due to low-field electrical appliance jamming singlechip application system.Through practice of intellective electric energy meter,mechanism of low-field electrical appliance jamming singlechip was discoursed.For example,there were electromagnetic interference of perceptual component,spark interference of contact terminal and singlechip application system can not work normaly because of electric power source of singlechip being jammed.The corresponding anti-jamming prescription are proposed such as hardware anti-jamming measures,software anti-jamming measures and anti-jamming measures in assemble technics.Through practice of intellective electric energy meter,the above-mentioned anti-jamming measures were proved to be effective.更多还原
