Concrete application example:
The present embodiment intelligent monitoring terminal applies, in micro-electrical network multi-agent system, also comprises micro-electrical network Agent, higher level's electrical network Agent in addition.The present embodiment intelligent monitoring terminal is the element agencies such as photovoltaic cell Agent, storage battery Agent, fuel cell Agent, wind energy turbine set Agent, load Agent.By the data-transformation facility in component module, mode and the micro-electrical network agency with request/response keeps in communication for they.Micro-electrical network Agent has comprised all micro-electrical network agencies, between each micro-electrical network agency, by communication modes, carry out a small amount of exchanges data, micro-electrical network Agent and higher level's electrical network Agent carry out the negotiation of control strategy in the mode of policy conferring by communication, and by response mode, control strategy is transferred to intelligent monitoring terminal, and control voluntarily corresponding agency by intelligent monitoring terminal.
 
Each Agent has data processing and communication function, and meanwhile, each Agent also has different separately functions: micro-electrical network Agent have aggregation of data processing, solution formulation, order issue and with the grid-connected function of major network; Photovoltaic cell Agent has MPPT maximum power point tracking (MPPT) function, cell panel monitoring and defencive function, inversion grid connection function; Fuel cell Agent has the monitoring of water treatment, fuel treatment and air supply, hydrogen-oxygen content and fuel and injects control, heat treatment, power adjustments and the function such as grid-connected; Storage battery Agent has the monitoring function to battery tension, electric current, energy storage, also has charging/discharging function and start and stop attributive function etc.
The hardware implementation scheme of intelligent monitoring terminal is as follows:
1, main control module
Main control module adopts the CPU architecture design of DSP+ARM double-core, comprises dsp chip and ARM chip, also comprises in addition display device and data storage module.
DSP is mainly as the platform that calculates every electric signal parameter, adopt TMS320F2812 chip, it is the fixed point 32 bit DSP chips on the C2000 platform released of American TI Company, dominant frequency reaches as high as 150 MHz, handling property can reach 150 MIPS, every instruction cycles 6.67 ns, can meet real-time demand well.In DSP, mainly complete the collection of the signal of telecommunication, the calculating of each monitoring variable, complete simultaneously and ARM between the synchronous transmission of result of calculation and real time data.
ARM interlock circuit is mainly realized distributed power source electrical parameter result is carried out to store and management.Master chip adopts AM3359, and 32 of Ta Shi TI company releases integrated ARM Cortex-A8 kernel are multi-functional, the ARM chip of low-power consumption, and highest frequency can reach 720 MHz.Hardware circuit comprises power module, memory module, and SD card module, USB module, touch screen module, network communication modules etc., adopt linux kernel, and stable and reliable for performance, the mechanism of multitask can effectively be managed various functions.
The transfer of data of DSP and ARM is adopted in two ways, and the one, serial ports SPI transmission, the 2nd, FIFO memorizer buffer mode.The parameter result drawing after DSP computing is due to data volume few (only having the parameters of 3 channel voltages and electric current etc.), and transmission not frequent (some s transmission 1 time), is mainly transferred to ARM by SPI serial mode.In AD sample rate, be (under signal fundamental frequency 50 Hz, each cycle sampled point is 256) in 12.8 k/s situations, the data volume that 3 channel voltage data add 3 channel current data is 76.8 k/s, data volume is larger, so adopt FIFO as buffer memory between DSP and ARM.
DSP and ARM data transmission circuit are as shown in Figure 3.FIFO model is SN74V235,2048 * 18-Bit capacity, and 3.3V power supply, can synchronously read and write, and the read-write cycle is 7.5 ns.The left side of FIFO is AD and DSP equipment, when AD being operated by DSP control, also FIFO is operated, the chip selection signal XZCSO1 of DSP connects WEN and writes clock enable signal, WCLK write clock signal by the read operation signal XRD of DSP to FIFO, completes like this and has also completed the storage of FIFO to data when reading AD image data.By the RESET of ARM, provided the RS reset signal of FIFO, data output pin DO ~ D15 meets ARM data wire DO ~ D15; The REN that ARM chip selection signal nGCS4 meets FIFO reads enable signal; CLKOUT connects and reads clock RCLK signal; By the nOE of ARM, provided the OE output bus enable signal of FIFO; The HF of FIFO connects the EINT2 external interrupt pin of ARM, for applying for, interrupts.When storage data reach 1k, FIFO will send half-full signal, and ARM will read this 1k data using this signal as interrupt signal, after there is out-of-limit judgement, determine whether these initial data are carried out to non-volatile memories again.
Main control module also comprises data storage module in addition.Data storage module mainly comprises synchronous DRAM (SDRAM), NORFLASH memory and NANDFLASH memory, and three completes different functions according to feature separately.
Synchronous DRAM part category is various, and native system has been selected IS42S16400 chip as required.This chip is the high speed SDRAM device of American I SSI company, and memory capacity is 8M byte, 16 bit data width.It is fast that it has read or write speed, stable performance, but easily lose program and the data that can be used in storage running, the speed of service of elevator system.In native system, two IS42S16400 are composed in parallel to the storage system of 32 bit wides.
That NORFLASH memory adopts is chip SST39VF160, and memory capacity is 2M, and bit wide is 16bit, and operating voltage is 3.3V, and power down is not lost, for program and some value data of solidification equipment.The present invention expands NORFLASH memory, and its memory space has increased one times.
The features such as that NANDFLASH memory adopts is the K9K2G08U0M of Samsung, and it is large that it has capacity, non-volatile, can be used to storage area for the microclimate data of micro-electric network information modeling at this device.
2, data acquisition module
Intelligent monitoring terminal will be to each unit operation conditions Real-Time Monitoring of micro-electrical network, and by data collecting module collected to data send to micro-electrical network Agent.Monitor data mainly comprises voltage, electric current, power and the frequency of system electrical network; The output voltage of inverter, electric current and power, and record every day electrical network and exchange input electric weight, DC side inversion electric weight, client's power consumption every day, every day battery discharge capacity, and inverter auxiliary contact state; Voltage, electric current, the power of photovoltaic panel output and the gross generation that records every day; Voltage, electric current, the power of blower fan output and the gross generation that records every day; The voltage of storage battery, electric current, power, temperature and record its running time, every day charge and discharge electric weight and total ampere-hour number that discharges and recharges.In addition, the data of collection also comprise the electric weight of voltage, electric current, power and every daily consumption of important load.
