Embodiment
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1; Urban distribution network cable circulation Monitoring Data supervisory relay device, by the CPU CPU, radio frequency communication unit, GSM/GPRS communication unit; Compositions such as RS-485 bus, solar powered power supply; It is characterized in that: solar powered power supply connects the CPU CPU, and the microprocessor of CPU processing unit adopts the ATmega64 single-chip microcomputer, and house dog is adopted X5043; The LED display circuit adopts MAX7219; The radio-frequency communication unit connects with the CPU processing unit and is connected, and the GSM/GPRS communication unit is sent to distant place computer system with data, and the RS-485 bus is connected with the CPU CPU.
During work
,As shown in Figure 1; Relay timesharing or receive the field data of gathering through the radio frequency communication mode data of collection in worksite in real time; Carry out Classification Management; If monitoring management can be repaiied and select to adopt the RS-485 bus mode to pass to computer system in the transformer station or among a small circle, a plurality of in a big way transformer stations cable monitoring then adopts the GSM/GPRS wireless communication mode to be sent to distant place computer management system.
As shown in Figure 2; The CPU processing unit mainly is made up of microprocessor, keyboard-display circuit, solar powered power supply etc.; Mainly receive the data of each collection point and carry out Classification Management, storage, be sent to distant place computer system by the GSM/GPRS wireless network through the radio frequency communication unit.
The radio frequency communication unit is made up of three parts: data are sent to the RS485 bus communication of computer management system in the radio frequency communication circuit of reception collection in worksite device data, the transformer station, data are sent to the GSM/GPRS module of distant place computer management system at a distance.Radio frequency communication circuit transmission distance is about 300 meters, the data transmission of completion and on-site data gathering device, and key wiring diagram is as shown in Figure 3.
The radio-frequency communication circuit:Radio communication is selected NRF905 monolithic wireless transceiver for use, and NRF905 monolithic wireless transceiver is operated in the ISM band of 433/868/915MHZ.By a fully-integrated frequency modulator, the receiver of a band detuner, a power amplifier, a crystal oscillator and a regulator are formed.About 300 meters of its communication distances, nRF905 should be finished writing configuration register earlier by MCU as required before operate as normal, or according to default configuration work.When sending data; MCU should place standby mode (the PWR_UP pin is low for high, TRX_CE pin) to nRF905 earlier; All write in the relevant register through spi bus send address and data to be sent then; Place sending mode (PWR_UP, TRX_CE and TX_EN put height entirely) to nRF905 afterwards, data will be gone out through antenna transmission automatically.If the automatic retransmission bit (AUTO_RETRAN) in the RF configuration register is made as effectively, packet will repeat constantly outwards to send out always, drags down TRX_CE up to MCU, withdraws from till the sending mode.For data are transmitted more reliably, suggestion this kind modes of using more.When receiving data, MCU finishes writing the receiver address in the RF configuration register in the standby mode of nRF905 earlier, puts it then in receiving mode (PWR_UP=1, TRX_CE=1, TX_EN=0), and nRF905 will the aerial carrier wave of automatic reception.If receive matching addresses and the correct valid data of verification, the DR pin can be put height automatically, and MCU can change it for standby mode after detecting this signal, from receive data register, read valid data through spi bus.
RS-485
Bus:According to on-site actual situations in transformer station or among a small circle cable circulation Monitoring Data can adopt the mode of RS-485 bus to transmit data; Each on-site data gathering monitoring device is serially connected on the bus; Distant place computer system is carried out swap data and information according to the corresponding address numbering; The RS-485 bussing technique is ripe, networking is simple, can satisfy on-the-spot actual needs.
GSM/GPRS
Communication unit:Because on-site data gathering monitoring dress disperses, the data management relay is far away from distant place computer management system, and data remote is defeated to be crucial, adopts the GSM/GPRS communication modes well to solve this problem.Shown in Figure 4 is the cut-away view of this used GSM/GPRS module, and module mainly is made up of the Zip socket of radio-frequency antenna, inner Flash, GSM BBP, coupling power supply and one 40 pin.Wherein the GSM BBP is a core component, and its effect is equivalent to a coprocessor, is used for handling the AT instruction that external system sends over through serial ports.The main modulation and demodulation that realize signal of radio-frequency antenna part realize the conversion of signals between external rf signal and the inner BBP, and the coupling power supply is that processor and radio frequency part provide required power supply.
To the AT command set of manipulating the GSM07.05 regulation of gsm module, single-chip microcomputer directly issues the AT order to gsm module through serial line interface, just can make things convenient for transmitting-receiving, inquiry and the management of the short message SMS that realizes GSM compactly.AT that single-chip microcomputer sends instruction is used for setting up communication link, and the command format frame of AT command set is all with the AT beginning, and " AT " perhaps the prefix of " at " must appear at the beginning of each order line.
The double frequency GSM/GPRS communication mould 2406A that the GSM/GPRS module adopts French Wavecom company to produce.Compare with like product, the Q2406A module dissipation is low---and the idle pulley maximum power dissipation is 3mA, and maximum power dissipation is 10 μ A under the dormant state.The Q2406A module only need extend out a SIM, and through communicating by letter between UART1 and the microprocessor, the TXD1 pin of UART1 is connected serially-transmitted data with microprocessor, and the RXD1 pin of UART1 is connected the serial received data with microprocessor; Microprocessor applications GSM AT instruction is operated module.When needing communication between data management relay and the host computer, microprocessor transmits and receive data through serial ports control 2406A.
