TH516C3 - Automatic meter reading system - Google Patents

Abstract

This automatic meter reading system It consists of 3 main sections: the read and write area, the data collector. And the main control center The reading and recording sections will be Assembled with a turntable meter Can be both inside and outside the meter To measure the rotation Then be calculated to save the kilowatt-hours before sending to the data collector via Low voltage cable When the data collector receives the data from it, read and write the values under the Same control then Will store the resulting value of each meter To send to the main control center when received Request or at the time specified The main control center stores this information in the base system. Information for further uses

Claims (1)

1.Electrical meter reading system by compressive this It consists of the functions of the following parts: the reading and recording section (RU), which consists of a sub-part, is a signal detector to convert the rotation of the plate into electrical pulse signal. Pulse (Pulse) processing circuit, which will calculate and receive commands from the data collection. And a transmitting circuit, which It serves to send and receive data through low voltage cables, data collector (CU), main control center (MCU), which makes it possible to read the electricity consumption of each user. Divided by period of use by adding electronic circuits to the old turntable meter The system will be able to send Such power usage data can automatically go to the main control center. The communication between the read and write (RU) and the data collector (CU) relies on the transmission of data on the power line (Power Line Carier) using the data signal mix principle. With the frequency range 33-38 KH z., Which has been proven to be able to transmit the best low-voltage power lines, in addition, it relies on signaling in the range where the line voltage approaches 0 vol Which is the period with little noise This relies on the delay of the Trigger signal for 6.8 ms after the voltage in the system is 0 volts. The data collector (CU) and the main control center (MCU) can be contacted in many ways through the most common mediums. 2. Automatic meter reading system. As per claim 1. There will be control and monitoring of the time between reading and recording (RU) and data collection (CU) sections. Time will be checked at intervals. The read and write (RU) and data collection (CU) sections exceed the specified time difference. The data collector (CU) is also 3.Automatic meter reading system According to the claim 1. There will be controls and checks. The data collector (CU) time itself. The data collector (CU) has two clock segments to allow the two clocks to calibrate themselves when the time difference is exceeded. Defined It will stop working in other parts and notify to the main control center (MCU) for the staff to correct the time to Next data collector (CU)
