Description

One may embed S. IU integrating meter, disaster prevention and security information of the gassing power meter {Both water, gas metering and disaster alarm, security data processing SIU contained watt hour meter}

The present invention is a utility company to configure a remote metering system by combining wireless communication such as mobile communication or power line communication with

The customer can install the water gas meter by wire or wirelessly by installing (or detachably sealing) the electricity meter without installing a system interface unit (SIU) that integrates remote meter reading, disaster prevention and security information of electric water gas. So

Integrate meter reading with water meter if necessary

It is usually used as a disaster prevention and security system such as detection and detection of harmful gas.If the SIU of electricity meter is in the process of metering electric water gas, if there is disaster prevention or security information such as gas leakage, it will be interrupted and interrupted the metering operation. Do the job first.

There is a remote metering system that accumulates the pulse signal generated from the meter by connecting a plurality of meters, such as electric water gas, to the central computer separately installed, and delivers it to the central computer through a wired / wireless communication network. As the security system communication network was installed and operated separately, it was economically wasteful.

Its primary purpose is to use it as a communication network for security systems.

In addition, there is no SIU that integrates their information in the customer, and built-in (or removable sealing) power meter, disaster prevention detectors such as water gas meter and gas leakage detector with pulse output function are binary for each pulse generator of each device. By inserting a resistor corresponding to the value in multiples and binding it in parallel to 2-Wire and connecting it with a power meter and one connection terminal, it is possible to detect information such as pulse and gas leakage of each device and detect fraud such as disconnection short circuit. Connect the security detection system to a separate connection terminal

If the location of the disaster prevention detector such as water gas meter, gas leak detector, or security system is far from the electricity meter, or if wired connection is inconvenient, place the wireless communication unit on the SIU of the electricity meter by the method of short-range wireless communication. It is a second object to provide a multi-function electricity meter that allows data communication with a wireless device.

In the case of PLC communication, in order to achieve the above object, the data concentrator of the transformer secondary line is provided with a power failure compensation circuit (including backup power supply) and a power failure detection unit, and a power meter of a consumer assigned with an ID for each phase is set for a predetermined time (Example 30 It maintains stable disaster prevention and security communication network by calling sequentially every second) to check for power failure or failure and to continuously monitor load of transformer and to notify computer of meter reading center if there is any abnormality.
