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 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 the data back to the central control center through local and group control center for billing task. Most of all, the AURS is not susceptible to light, electromagnetic interference. It is more rigid and better constructed than any previous designs.

Description

Automated Utility Reporting System Description
The AURS uses electronic watt-hour meter, as shown in Fig.l-le, which can measure voltage, current and phase angle between voltage and current. With all these data, the Consumer Data Unit Fig.1-3, can monitor and calculate the total power consumed. Optical sensors/transmitters, are used to monitor the usage of water Fig.l-lW and natural gas Fig.l-IG. The optical sensor/transmitter includes probe, fibre optic Fig.1-2, optic- coupler, constant current source, amplifier and Mother board with display, the computer board is the model of MCS-51 serial. The meter-wheels of the water and natural gas must be made of ABS plastic and put on a tiny dot of aluminum on the wheel. The probe should be aligned with the dot of aluminum on the wheel Fig.l-lW-lG, and then fastened and sealed, the water meter will be made of two separate compartments in order to prevent corrosion and dirt from building on components. The second com¬ partment will prevent leakage and tampering from occurring magnets will be placed on both wheels allowing them to turn at the same rate. The wheel in the second compartment will be monitored by fibre optics. The probe is connected to the optic- coupler with the fibre 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 power. A temperature sensor is .connected with a heater is installed for low temperature compensation. This is part of the system for monitoring. The main computer board, with interface through local control unit Fig.1-5 and group control centre Fig.1-7, is connected to the central control centre Fig.1-9. The 110V-220V electrical power line Fig.1-4 as data BUS from Consumer Data Unit Fig.1-3 to connect to Local Control Unit Fig.1-5. Other ways of data BUS can be used for this system Fig.1-6-8, such as fibre optic, telephone line or radio system to connect from Consumer Data Unit to Central Control Centre. The computer in the central control centre the processes all the data for billing. This system will save the expense and inconvience of mailing the bills to the consumers. The CDU will display the Billing for each month.
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.
Sensor Units
Unique and separate sensors for each utility lines are installed for each entry ports on a consumer's site. These sensors are identified as Electrical Sensor Unit (ESU) and Gas Sensor Unit
(GSU) and Water Sensor Unit (WSU) . Each unit collects utility consumption data, monitors the unit health condition by a builtin-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 monitoring network. The CDU modulates all data into a frequencymodulated (FM) signal and sends the signal by 110-220V power 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/Ni-Cad Battery
Local Control Unit
Each power transformer that provides the area with have a local control unit (LCU), LCU communicates with a Group Control Unit (GCU) by a high voltage power line or telephone line, fibre optic, or radio system for data reporting, clock update and taking commands from the GCU. A LCU collects up to five digit number 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 such as a new account or a closed account. A LCU can make an automatic and periodic data reporting based on the CCU direction, or the LCU may also make an unscheduled reporting when the LCU is interrogated by the CCU. A LCU consists of the following elements:
-Micro-processor
-Electronic data Accumulator
-Erasable electronic memory
-FM modulator/demodulator
-FM transceiver
-Telephone modem
-Optical sensor/transmitter
-Built-in-test-network
-Temperature sensor/heating unit
-LCU program
-Power supply/Ni-Cad Battery
Group Control Unit
A Group Control Unit (GCU) transmits data between LCU to CCU. A GCU consists of the following element: -Same as above (LCU)
Central Control Unit
A Central Control Unit (CCU) controls all of the units of the AURS system. A CCU consist of the following element: -AURS program
