Description
The utility model relates to the centralized automatic meter-reading device of the various table counting of a kind of concentrated telnet user side certificate.
The development and production producer of centralized automatic meter-reading device is numerous at present, and its product is also varied, but does not have a kind of system of maturation to be used in a large number as yet.Its main cause is that it adopts pulse to pass working method of number, and the reading that promptly will show earlier to count is converted to pulse signal, by the circuit that lays specially with data upload.Though can realize meter-reading function, increased the workload and the engineering cost of cable wiring manufacture greatly, pulse passes the poor reliability of number in addition, thereby is difficult to apply.High speed development along with electronic technology and computer technology, the low voltage power line carrier automatic meter reading system has appearred recent years, as " the electric energy meter Automatic meter reading system " that discloses in " electrical measurement and instrument " (19995 the 8th phases), this system is made of the teleterminal system (RTU) and the centralized automatic meter-reading supervisor (CTRU) that are installed together with user's watt-hour meter, adopts the communication of frequency shift keying (FSK) power line carrier half-duplex mode between CTRU and the RTU.The shortcoming of this mode is a poor anti jamming capability, data communication bit error rate height.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing centralized automatic meter-reading device, and the centralized automatic meter-reading that a kind of antijamming capability is strong, reliability is high, configuration is flexible, widely applicable device is provided.
The concentrator that the centralized automatic meter-reading device of realizing the utility model purpose joins by several data acquisition units that join with the table meter of posting a letter of each user side respectively with by line of electric force and each data acquisition unit and constituted with terminal data processor that the concentrator signal output part joins, it is characterized in that described data acquisition unit is by the pulsed signal circuit, the pulse signal treatment circuit that joins with the pulsed signal circuit, the modulation circuit that joins with the pulse signal treatment circuit, the power output circuit and the coupling transformer that join with modulation circuit constitute, described concentrator is by phase-switching circuit, the carrier modulation circuit that joins with phase-switching circuit, the data processing circuit that joins with the carrier modulation circuit and constitute with modification output circuit that data processing circuit joins.
Principle of work of the present utility model is as follows:
Collector with this device during use is connected with user's the table meter of posting a letter by lead, the table meter of posting a letter of user side can be table meters such as the watt-hour meter, gas meter, water meter of tape pulse output, if the table of user side is counted common stem-winder meter, then can in original table meter, install corresponding sensing device additional and repack it into can send pulse signal table meter of posting a letter.By the pulse signal input collector of the table meter output of respectively posting a letter, through collector gather, add up, storage, modulation treatment and be loaded into line of electric force through power transmission of electricity road and coupling transformer, on line of electric force, adopt the extension frequency carrier mechanics of communication to transmit signal.The phase-switching circuit of concentrator takes out the signal on the three-phase power line respectively, process carrier modulation circuit is defeated by data processing circuit after mediating and handling, after data are carried out relevant treatment, deliver to the terminal data processor by modification output circuit again, by the usage data that demonstrates or print each meter of checking meter after the terminal data processor processing and the amount of money etc.
Described terminal data processor can be a hand-held computer, carries each concentrator position by managerial personnel, and the on-the-spot reading of data that is connected with concentrator is gone forward side by side and demonstrated the usage data of being checked meter and the amount of money etc. after the line correlation processing.Also can print by on-the-spot external printer.Concentrator can be distinguished by platform and establish, or the condition of looking sets up separately by each section, each big Charging Detail Record unit.
Described terminal data processor can also be one be located in the administrative authority computing machine and with joining LAN (Local Area Network) of this computing machine and large screen display device.Data transmission between concentrator and the computing machine, the ripe communication modes of can choosing any one kind of them: phone, optical fiber, wireless mode.For example: can by modem signal be transmitted by telephone wire at modem of output termination of concentrator, take out signal with a modem from telephone line again, after demodulation process, be defeated by computing machine.
As a same reason, concentrator is to adopting RS232 serial communication, RS485 communication, infrared ray or MODEM mode to connect between the terminal data processor.For ease of the realization of these modes, can a communication translation interface be set the modification output circuit in concentrator.
The utility model is compared with existing automatic meter reading system, has the following advantages:
1. the signal and communication mode of this device is in the extension frequency carrier mode, the reliability height;
2. this device can be realized the Dynamic Multi-Pathing technology, this technology makes the collector of user side make it to have the signal relay function by its data processing circuit and corresponding program, need not special signal relay amplifier, can make signal relay transmission in the electric power networking, solve preferably in the electric line carrier communication disturb strong, problem such as it is big to decay;
3. this device configuration is flexible, and construction is easy, and cost is low, is suitable for newly developed area, the construction of old liberated area kilowatt meter reading-out system, transformation;
This device also can have the characteristics of permanent preservation under the meter cumulative data power down of checking meter, water meter, gas meter still can continue to count 50-100 hour when having a power failure; In the time of can also realizing time sharing meter, system school, dialing automatically, regularly and copy and accept user data etc. in real time;
5. widely applicable---can be used for the remote automatic meter reading control of the water, electricity and gas centralized automatic meter-reading of residential building sub-district, industrial and mining enterprises, public institution and power supply and distribution of electric power, water supply, heating industry.
Below in conjunction with drawings and Examples the utility model is described further, but content of the present utility model is not limited in this embodiment.
