Embodiment
Referring to accompanying drawing 1, a kind of automated wireless kilowatt meter reading-out system with outage control of the utility model is made up of RS485 ammeter, SR-137C type radio meter register terminal, sub-district concentrator, write by hand device, data processing centre (DPC).Data processing centre (DPC) is transferred to the sub-district concentrator by Internet+GPRS/CDMA public network wireless transmission method with instruction, the sub-district concentrator is also got in touch with the radio meter register terminal mutually through the micropower wireless transmission, and copy the continuous data and the table tool parameter of getting each subscriber's meter tool in real time, can carry out the function of open and close ammeter.
SR-137C type radio meter register terminal has the one-level relaying and transmits routing function, when radio meter register terminal (first) far away with the sub-district concentrator and that exceed range for wireless communication will communicate with the sub-district concentrator, can carry out the transfer route by near the radio meter register terminal (second) the concentrator of sub-district, thereby reach the purpose of stabilized communication.One-level forwarding capability between sub-district concentrator and the radio meter register terminal gets a promotion the distance of copying privately.The relay mode that this relaying is transmitted not only makes the distance of checking meter widen, and also makes the installation of system seem convenient flexible.
System allows to use wireless transmission method at the scene by the write by hand device, copies the content of getting the radio meter register terminal.And then copy the data importing Data Control Center of getting in the write by hand device through RS-232 interface.
According to Fig. 2, the radio meter register terminal mainly is made of five parts: power unit, the function of mainly finishing are that alternating current 220V is converted to stable direct current 5V power supply; Wireless transport module mainly carries out the wireless transmission of data; The RS485 interface circuit is mainly finished the conversion of RS485 level; The terminal coded stack is according to user's needs storage terminal number and information; Control relay circuit, the open and close state of control ammeter.
The radio meter register terminal receives the data of ammeter by the RS485 interface circuit, and leaves in the address of the relative users that pre-sets in the terminal coded stack.Give data processing centre (DPC) through the wireless transmit mode with data and information transmission then.The sub-district concentrator is handled accordingly to copying the data of fetching, as satisfies time-sharing measurement valuation etc.; User profile in the concentrator of sub-district is grasped and is revised by computer controlling center.Also can be provided with and change, comprise: the change of the interpolation of user's table number, change, deletion and concentrator address by the write by hand device.
Microprocessor ATMEGA168 pilot relay control circuit in the radio meter register terminal, open and close are 20 tunnel controlled ammeter nearly.
Can increase cold shock protection electric source filter circuit in the radio meter register terminal, have safeguard functions such as surge impact, when the circuit supply quality of assurance own, reduce interference supply line.
Taked non-volatile assurance system in the radio meter register terminal.By FM24C04 sections electrical storage, can effectively overcome the loss of data or the reading error that cause because of power failure.These ferroelectric memorys can unlimitedly write data, and power down obliterated data not.This with most computers in the memory chip of the random access memory used obviously different, the latter writes the indegree restriction.In addition, this ferroelectric material chip is littler than the electric energy that common random access memory chip consumes, and this can reach and reduce ferroelectric material power consumption, the service time of improving battery.And the speed of this ferroelectric RAM restore data, also faster than the transistor flash of light storer that digital camera uses.
Microprocessor is (RISC) reduced instruction set computer high-speed microprocessor of band enhancement mode built-in FLASH, benefit is that core cpu is easy to just to promote usefulness and consumed power is low, possess highly reliable house dog (Watchdog) circuit and Brown-out testing circuit, can reliably working under complex environment with the assurance system.
The radio meter register terminal is furnished with rechargeable battery in addition, and available when having a power failure, other times are in charged state.
Wireless transport module adopts the double-direction radio digital transmission module SRWF-508 product of Shanghai Tangray Information Technology Co., Ltd..
Fig. 3 is the electrical schematic diagram of radio meter register terminal.The main body of radio meter register terminal is 8 AVR single chip computer AT MEGA168 of U.S. Etta Man, be the reduced instruction set computer high-speed microprocessor (RISC) of the built-in Flash of enhancement mode, the control relay circuit of Xiang Lianing, SRWF-508 wireless transport module and 75176 type RS-485 interface circuits, power supply constitute the radio meter register terminal therewith.
The sub-district concentrator carries out respective handling to the data from the radio meter register terminal: as regularly freezing to show the tool continuous data, copy and get table tool continuous data and satisfy time-sharing measurement valuation etc. in real time, and in the storer that is stored in.Be transferred to remote data processing center by GPRS; Also can data be copied and get in the write by hand device, and then import data processing centre (DPC) through wireless transmission.
Fig. 4 is the block scheme of control relay circuit in the radio meter register terminal.Microprocessor carries out multichannel through the driving of TD62783 interface and receiving chip and 74HC238 type 3-8 demoder and selects, in by the transmission of TLP521 type photoelectrical coupler, isolate out extraneous next noise, drive ULN2803 high-voltage large current Da Lindun Mo body pipe array at last, thereby the actuating of relay of control appointment, go the corresponding ammeter terminal of open and close, at most the open and close state of may command 20 family ammeters.
