Abstract
Abstract Currently, collecting the meter readings of water, electrical power and natural gas is based on on-site inspection, no matter in urban or rural areas. It requires a large amount of manpower to collect data and make bills for charging.
The Automated Utility Reporting System ( AURS ) is designed mainly to save the manpower for collecting meter readings of water, electrical power and natural gas. The AURS uses an electrical power, and optic sensors are used to monitor the usage of water and natural gas. The AURS uses electrical power lines or fiber optic to send all data back to central control center through local and group control center for billing task.
Most of all, the AURS is not susceptible to light, electro-magnetic interference. It's rigid and well-constructed more than any previous designs.
The Automated Utility Reporting System ( AURS ) is designed mainly to save the manpower for collecting meter readings of water, electrical power and natural gas. The AURS uses an electrical power, and optic sensors are used to monitor the usage of water and natural gas. The AURS uses electrical power lines or fiber optic to send all data back to central control center through local and group control center for billing task.
Most of all, the AURS is not susceptible to light, electro-magnetic interference. It's rigid and well-constructed more than any previous designs.
Description
2. System Description The AURS uses electronic watt-hour meter, as shown in Fig.l-le, which can measure voltage, current and phase angle bet~een voltage and current. With all these data, the Consumer Data Unit Fig.1-3, can monitor and calculate the to~al power consumed. Optical sen-sors/transmitters, are used to monitor the usage of water Fig.l lW
and natural gas Fig.l-lG. The optical sensor/transmitter includes probe, fiber optic Fig.1-2, optic-coupler, constant current sourcei amplifier and Mother board with display. The computer board is the model of ~CS-51 serial. The meter-~heels of the water and natural gas must be made of aluminum or put on a layer of aluminum. The probe should be aligned with wheels Fig.l-lW-lG, and then fastened and sealed. The probe is connected to the optic-coupler with the fiber optic. The output of the optic-coupler is connected to the input of the amplifier. Then, the output of the amplifier is input to the Consumer Data Unit. A Ni-Cad Battery is used as back-up po-wer. A temperature sensor connected with a hea~er is installed for low temperature compensation. This is part of the system for moni-toring. The main computer board, with interface through local con-trol unit Fig.l-5 and group control center Fig.1-7, is connected to the central control center Fig.l-9. The llOV-220V electrical power line Fig.1-4 is used as data bus between Consumer Data Unit Fig.1-3 and local cOntrol unit Fig.1-5, and then uses, high voltage electr-ical power line Fig.1-6 as data bus to connect to connect to central control center Fig.1-7. Other ways of data bus can be used for this system Fig.1-6-8, such as fiber optic, telephone line or radio sys-tem to connect directly from Consumer Data Unit to Central Control Center. The computer in the central control center the processes al the data for billing.
The AURS also provide fault alarm system, and With the MCS-51 computer board installed, it can afford many fantasy functions such as detection of electricity stealing.

2~78~is Sensor Units Unique and separate sensors for each utility lines are installed ar each entry ports on a consumer's site. These sensors are iden-tified as Electrical Sensor Unit (ESU), Water Sensor Unit (WSU) and Gas Sensor Unit (GSU). Each unit collects utility consumption data, monitors the unit health condition by a built-in-test-network (BITN) and reports the information to a Consumer Data Unit (CDU). Each sensor unit consists of the following elements:
-micro-processor -Utility measuring device -Optical sensor/transmitter -Built-in-test-network -Computation algorithm -Power supply Consumer Data Unit The CDU Communicates with Local Control Unit (LCU) by the power line for the data reporting. A CDU with a unique identification number continuously accumulates utility data for each sensor units and stores BITN data if reported by any sensor unit or its own mon-itoring network. The CDU modulates all data into a frequency-modulated (FM) signal and sends the signal by 110-220V po~er line to a LCU when a request is received from the LCU. The CDU consists of the following elements:
-Micro-processor LCD display -Electronic data accumulator -Erasable electronic memory -Sensor interface circuit -FM Modulator/demodulator -FM transceiver -Built-in-test-network -CDU Program -Temperature sensor/heating unit ; -Power supply Local Control Unit ; Each power transformer that provides the area will have a local control unit (LCU), LCU communicates with a Group Control Unit (GCU) by a high voltage power line or telephone line, fiber optic, or radio system for data reporting, clock update and taking commands from the GCU. A LCU collects up to xxxxx (numbe~rs;i-- of individual consumer accounts by taking the data from -the CDUs. Actual number of CDUs assigned to a LCU determines by the Central Control Unit which has all account information including geographical location, sensor ~identification number and account status su~h~asa new~.acaount or a closed account.
A LCU can make an automatic and peri~ic data reporting based on the CCU direction, or the LCU may als~make a~ unscheduled rep-_~-orting when the LCU is interrogated by the CCU. A LCU consists of the following elements:
