Description
Technical field
The utility model relates to a kind of gateway system, relates in particular to a kind of high reliability wireless gateway system with autostore function.
Background technology
Gateway claims again gateway, protocol converter.Gateway to realize network interconnection, is the most complicated network interconnection apparatus, network interconnection on transport layer, only is used for two network interconnections that upper-layer protocol is different.The structure of gateway is also similar with router, and different is interconnection layer.Gateway both can be used for the wide area network interconnection, also can be used for local area network interconnection.Gateway is a kind of computer system or equipment of changing important task that serves as, and using different communication protocol, data format or language, even between the diverse two kinds of systems of architecture, gateway is a translater.Just convey a message simply differently from bridge, gateway will be repacked the information of receiving, with the demand of adaptation to end system.Simultaneously, gateway also can provide and filter and safety function.The various gateways that occur at present, for its reasons in structure, function singleness can not realize the functions such as autostore, has limited greatly the new development of gateway.
The utility model content
In order to solve the above-mentioned technical problem that exists in the background technology, the utility model provides a kind of and can store data, autgmentability is strong, the safe and reliable and low high reliability wireless gateway system with autostore function that consumes energy.
Technical solution of the present utility model is: the utility model provides a kind of high reliability wireless gateway system with autostore function, and its special character is: the data storage cell that described high reliability wireless gateway system with autostore function comprises for the CPU element of data being processed and being coordinated to control and is used for data are stored; Described data storage cell access CPU element.
Said memory cells includes but not limited to SD storage card and hard disk.
Above-mentioned CPU element comprises MCU, house dog and jtag port; Described house dog and jtag port access respectively MCU.
When said memory cells was the SD storage card, described SD storage card was by SPI mode of operation access MCU.
The capacity of above-mentioned SD storage card is 1G, 2G, 4G, 8G or 16G.
Above-mentioned MCU adopts the Atmega128 single-chip microcomputer.
The utility model has the advantages that:
The utility model provides a kind of high reliability wireless gateway system with autostore function, this gateway system is owing to containing the data storage cell that data are stored, memory devices such as SD storage card or hard disk, can directly be stored in data or the packet that receives in the data storage cell, solved the function that existing gateway can not be stored, because the SD storage card of different capabilities can be supported in SD storage card unit, further realizes autgmentability of the present utility model; The MCU unit that second the utility model adopts contains system reset and down Monitor Unit circuit, and during detection of power loss, when the externally fed inefficacy, gateway just is under the power-down state, at this moment blinking red lamp.Low electro-detection if externally fed is effective, is not just enabled this function; If externally fed lost efficacy, just enable this function.Simultaneously, this unit also contains system clock, can regulate in real time the time, revises the time of gateway with handheld device, has realized automatic time service.
Description of drawings
Fig. 1 is the principle framework schematic diagram with high reliability wireless gateway system of autostore function provided by the utility model;
Wherein:
The 1-CPU unit; The 2-data storage cell.
Embodiment
Referring to Fig. 1, the utility model provides a kind of high reliability wireless gateway system with autostore function, the data storage cell 2 that this high reliability wireless gateway system with autostore function comprises for the CPU element 1 of data being processed and being coordinated to control and is used for data are stored; Data storage cell 2 access CPU element 1.
Memory cell includes but not limited to SD storage card and hard disk, so long as can all can be used for technical scheme provided by the utility model to the computer hardware equipment that data or packet are stored.
CPU element 1 comprises MCU, house dog and jtag port; House dog and jtag port access respectively MCU.
The MCU that the utility model adopts is the Atmega128 single-chip microcomputer that adopts atmel corp, and the ATmega128 key property is as follows: the AVR8 bit microprocessor of high-performance, low-power consumption; Advanced risc architecture; Non-volatile program and data storage; Jtag port (with the IEEE1149.1 operating such); The peripheral hardware characteristics: two have independently 8 bit timing device/counters of pre-divider and comparator function; Two 16 bit timing device/counters with pre-divider, comparing function and capture function; 8 tunnel 10 ADC; I/O and encapsulation; 64 pin TQFP encapsulation; Operating voltage: 3.3V; The speed of service: 8MHz.
When memory cell was the SD storage card, the SD storage card adopted the SPI mode of operation and is connected with the PA port of MCU; Support the SD storage card (for example: 1G, 2G, 4G, 8G, 16G) of various capacity.
The serial ports of MCU drives chip (MAX3222E) by RS232 and is connected to the DB9 connector, and baud rate is 38400bit/s; PCF8563 communicates by letter with MCU by the IIC interface; PCF8563 adopts dual power supply, and (system power supply VD+3.3V and button cell+3V) even when system power failure, also can guarantee to provide accurately real-time clock.
Working mechanism of the present utility model is: gateway is played timestamp and storage to data or packet (comprising: transducer, relaying heartbeat packet, gateway heartbeat packet).Stamp timestamp by the data that radio frequency unit is sent back, deposit in the SD storage card on the one hand, pass in the server by Ethernet interface on the one hand, pass on the serial ports on the one hand, the work of this three aspects: is independently, mutually noninterfere.The utility model is when specific works, and the function with high reliability wireless gateway system of autostore function is realized by embedded software, mainly is divided into three layers: hardware layer, network layer, application layer.The function that system provides should comprise hardware abstraction, Clock management, memory management, routing management, task processing.Gateway is stamped the data collected or packet to be stored in the memory cell after the time and (for example is stored in the SD storage card), the user can download or derive data or the packet of storing in the memory cell in needs, the user also can say the word to gateway, obtains to own/specified node past a certain section measurement of time data.Handheld device can be revised the time of gateway, and server also can be revised the time of gateway.
