Definitions
- 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.
- 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.
- ESU Electrical Sensor Unit
- Gas Sensor Unit Gas Sensor Unit
- GSU Water Sensor Unit
- WSU Water Sensor Unit
- Each unit collects utility consumption data, monitors the unit health condition by a builtin-test-network (BITN) and reports the information to a
- BITN builtin-test-network
- Each sensor unit consists of the following elements:
- the CDU Communicates with Local Control Unit (LCU) by the power line for the data reporting.
- LCU Local Control Unit
- 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.
- FM frequencymodulated
- CDU consists of the following elements:
- 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:
- a Group Control Unit transmits data between LCU to CCU.
- a GCU consists of the following element: -Same as above (LCU)
- a Central Control Unit controls all of the units of the AURS system.
- a CCU consist of the following element: -AURS program
- ESU Electrical Sensor Unit
- GSU Gas Sensor Unit
- CDU Consumer Data Unit
- LCU Local Control Unit
- GCU Group Control Unit
- CPU Central Control Unit

Abstract
A l'heure actuelle, les relevés des consommations d'eau, d'électricité et de gaz naturel sont basés sur une inspection sur place, que ce soit dans des zones urbaines ou rurales. Cela nécessite beaucoup de main d'÷uvre pour relever les données et établir les factures de consommation. Le Système de Relevé Automatisé des Services publics (SRAS) est conçu principalement pour épargner de la main d'÷uvre effectuant les relevés de consommation d'eau, d'électricité et de gaz naturel. Le SRAS utilise le courant électrique et des détecteurs optiques sont utilisés pour contrôler la consommation d'eau et de gaz naturel. Le SRAS utilise des lignes de courant électrique ou des fibres optiques pour retourner toutes les données au centre de contrôle à travers des centres de contrôle locaux et groupés pour les opérations de facturation. Par dessus tout, le SRAS n'est pas sensible à la lumière ni aux interférences électromagnétiques. Sa construction est rigide et mieux réalisée que tous les concepts précédents.
