Title: Automatic synchronous switching system for demand meter
Inventor: KASAI KOJI
IPC: H02J3/00
Filed: 1989-12-29
Abstract: PURPOSE:To reduce the number of setting term and to simplity the operation by continuously confirming existence of an external synchronizing input signal in a specific time signal at an incorporated timer section and automatically switching the synchronizing system. CONSTITUTION:When both a specific time 32 and an external synchronizing signal pulse 36 are H, a switching signal goes H. since an external synchronizing signal 37 is detected during next specific time 33, duration of the switching signal at H level is updated. Since no external synchronizing signal is detected during a specific time 34, the switching signal goes to L level at the time point of a specific time signal (T1) and switching is made to a clock time fixed synchronizing system. In other words, since the operation is switched at every T1 time, switching is made to the external synchronizing system upon detection of next external synchronizing signal.
