Title: Method for measuring use time of electric energy and use time electric meter
IPC: G04G99/00
Filed: 1992-09-21
Abstract: PURPOSE: To easily reduce a frequency with which a recorder must be programmed with updated calendar events by processing event data to discriminate whether the current date corresponds to the date of an event or not. CONSTITUTION: For the purpose of obtaining TOU(time of use) information, a meter reader connects an electronic data retrieval means to a meter, and a retrieval means reads out a pulse calculation value and stores it in a memory location of a meter recorder. Next, this information is returned to a center location by the meter reader and is further processed for generation of a bill. The method to store a pulse besides the time is dependent upon whether a specific day when the pulse is received is a holiday or a weekday. A microcontroller 10 scans a memory 12 with a specific location for discrimination to discriminate whether the current date correspons to a regular annual event 16 or an event specific to the year.
