摘要
BiLOCK型计算机联锁的继电接口采集电路,采用中接点与前后接点相位差比较的方式,与单一的采集回路电压相比可靠性大大提高;解决了前后接点混线问题,节省线缆;采用第三方比较生成条件电源,实现最高的诊断覆盖率。
The relay interface acquisition circuit of BiLOCK type computer interlocking adopts the comparison of phase difference of middle contact and that of front contact and back contact.Compared with a single acquisition circuit voltage,its reliability has been greatly improved.The problem of the mixing line between front contact and back contact is solved and the use of cable is also saved.And the highest rate of diagnostic coverage can be achieved by comparing to a third party to generate conditional power source.
