Zigbee terminal node can be powered with battery, and electric power source pair of module Zigbee telegon and STM32 whole system are powered, and by voltage stabilizing chip burning voltage, its circuit diagram is as shown in Figure 2.
3, serial port circuit design
Serial port circuit can realize the communication between STM32 and host computer, simultaneously serial ports STM32 chip can be downloaded program, it is simple to being managed the function of system, its circuit is as shown in Figure 3.
Four, Embedded Hardware Design
Native system selects STM32F103VET6 as main control chip, STM32F103 series microprocessor is first 32 standard RISC (reduced instruction set computer) processors based on ARM Cortex-M3 architecture, the highest code efficiency is provided, usual 8 memory spaces with sixteen-bit system have played the high-performance of ARM kernel.This series microprocessor operating frequency is 72MHz, the flash storage of built-in up to 128K byte and the SRAM of 20K byte, has abundant general purpose I/O port.Communication interface containing abundant: three USART asynchronous serial communication interfaces, two I2C interfaces, two SPI interface, a CAN interface and a USB interface, provides guarantee for realizing data communication.
Along with the continuous renewal of electronic product, the exploitation of various display interfaces gets more and more, and owing to the cost performance of TFT color screen is high, thus is widely used on various electronic equipment as display screen.STM32 Series uses a kind of novel memory expansion technology FSMC, has the advantage of uniqueness, according to systematic difference needs, can carry out the extension of dissimilar Large Copacity static memory easily in terms of outside memory expansion.
The design uses 3.2 cun of resolution ratio to be the liquid crystal display of 320 × 240, and uses ILI9341 chip controls liquid crystal display, the running status of washing machine is shown, LCD shows the interface circuit with STM32 as shown in figs. 4 and 5.
Five, the Software for Design of system
The washing machine monitoring system of ZigBee technology, realize the running status of every washing machine is acquired, every washing machine can be numbered, numbering is from 1 to N, every washing machine is provided with vibrating sensor and CC2530 module, each washing machine is exactly a Zigbee wireless sensor network end nodes, numbers as numbering with washing machine.One Zigbee wireless sensor network is at least made up of telegon and terminal node, and the data of sensor are acquired and are transferred to telegon by Zigbee network by each terminal node, and data are processed and show by STM32 single-chip microcomputer.Program flow diagram is as shown in accompanying drawing 6,7 and 8.
In real life, the data monitored are divided into " working " and " idle state " through row analyzing and processing, the running status of washing machine;But it is likely to occur " idle state " that washing machine is false, it is believed that washing machine can be divided into following grade according to its standby time idle state:
We can go to select washing machine to use according to the state of LCD liquid crystal display, and this greatly facilitates the life of classmates.
Six, sum up
The present embodiment is by the application to Zigbee wireless sensor network, with dormitory washing machine as object, devises washing machine based on ZigBee technology monitoring system, it is achieved that be monitored the running status of all public washing machine of each.Solve the state that classmates do not know that washing machine runs and cause the whitest problem run, allow classmates at dormitory it is known that the state of every washing machine, to such an extent as to know whether available free washing machine, it is to avoid the waste of unnecessary time and efforts.The design equipment is easy for installation, and with low cost, very practical, has considerable economic benefit.
The description of such scheme is the invention being understood that for ease of those skilled in the art and using.Embodiment obviously easily can be made various amendment by person skilled in the art.Therefore, the invention is not restricted to above-mentioned solid yardage case, those skilled in the art's the method according to the invention, the improvement made without departing from scope and amendment all should be within protection scope of the present invention.
