| 摘 要： | 计数器是自动控制系统中常用的控制及显示元件。其工作的可靠性和抗扰性直接影响到控制系统的下沉运行。对于计数频率要求不高，计数值不多且有强干扰的场合，采用电子型计数器不经济，因为它必须配备抗干扰电源；而采用电磁型计数器也不尽如人意，因为它的可靠性差，寿命短。

| Abstract: | A counter is a kind of control and display unit by using of automatic control systems.Its reliability and anti disturbance affect normal running of the control systems.In the case of lower counting frequency,lower counting value and strong disturbance,adoption of electronic counter is uneconomical because it must be equiped with an anti disturbance power source, adoption of electromagnetic counter is unsuitable because its reliability is poor and its life is short.In the case of above mentioned,an anti disturbance counter which consists of relays and electronic components designed by using of logical operation.The counter is simple in structure,lower in cost and convenient in maintenance. |
