【摘要】：無線傳感器網(wǎng)絡(luò)(WSN)主要的功能是用于跟蹤和監(jiān)控,到目前為止,對WSN很多人的工作都集中在應(yīng)用層、路由層以及鏈路層,然而,在傳感器節(jié)點(diǎn)本身的監(jiān)視,管理以及控制上做的工作卻非常少。如果傳感器節(jié)點(diǎn)布置在人工難以維護(hù)的地方,那么節(jié)點(diǎn)系統(tǒng)的強(qiáng)壯性應(yīng)該是最應(yīng)該考慮的問題。為了解決這個問題,本文提出了“一鍵還原”功能,傳感器節(jié)點(diǎn)將錯誤消息以多跳的形式發(fā)送到網(wǎng)關(guān)直至控制中心,然后,只需按下傳感器節(jié)點(diǎn)上的還原按鍵或者手動從網(wǎng)關(guān)到節(jié)點(diǎn)發(fā)送一條系統(tǒng)還原指令就可以把對應(yīng)節(jié)點(diǎn)的系統(tǒng)恢復(fù)到初始狀態(tài)。另外,網(wǎng)關(guān)的可視化界面使得用戶可以高效管理網(wǎng)絡(luò)中的任一節(jié)點(diǎn)。本文采用的硬件平臺是基于德州儀器CC2530的片上系統(tǒng)開發(fā)設(shè)計(jì)的,還為網(wǎng)關(guān)配備了觸摸顯示屏。軟件系統(tǒng)是基于Linux開發(fā)的,便于可視化操作,而節(jié)點(diǎn)系統(tǒng)以德州儀器公司(TI)研發(fā)的Z-Stack協(xié)議棧為核心,主要在應(yīng)用層以及硬件抽象層做了相應(yīng)的修改以適合我們開發(fā)。對于“一鍵還原”模塊采用的硬件平臺是恩智浦的基于ARM Cortex-M0核心的LPC1114低功耗32位微控制器,面向8、16位微處理器應(yīng)用,它相比8、16位架構(gòu)的其它處理器來說有效的降低了代碼長度。此外,需要還原的代碼被存儲在一塊特制的儲存器W25X16中,它的優(yōu)點(diǎn)就是功耗極低且非常適合做代碼下載應(yīng)用。還原過程就是LPC1114控制將W25X16中的程序讀出來然后寫入CC2530中,這樣就實(shí)現(xiàn)了“一鍵還原”過程。經(jīng)過大量的實(shí)際測試,測試結(jié)果表明本文的軟硬件系統(tǒng)都滿足了設(shè)計(jì)要求,明顯提高了節(jié)點(diǎn)的實(shí)際使用壽命。
[Abstract]:The main function of wireless sensor network (WSN) is to track and monitor WSN. Up to now, many people have focused on application layer, routing layer and link layer. Management and control do very little work. If sensor nodes are arranged in places where it is difficult to maintain manually, the robustness of the node system should be the most important consideration. In order to solve this problem, this paper proposes a "one-click restore" function, in which the sensor node sends the error message to the gateway in the form of multiple hops to the control center, and then, By pressing the restore button on the sensor node or manually sending a system restore instruction from the gateway to the node, the system of the corresponding node can be restored to its initial state. In addition, the visual interface of the gateway enables users to efficiently manage any node in the network. The hardware platform used in this paper is based on Texas Instruments CC2530 on-chip system design, and the gateway is equipped with touch display screen. The software system is developed based on Linux, which is convenient for visual operation. The node system is based on the Z-Stack protocol stack developed by Texas Instruments Company (TI), which is mainly modified in the application layer and the hardware abstraction layer to suit our development. The hardware platform used in the "one-click restore" module is the LPC1114 low power 32-bit microcontroller based on arm Cortex-M0 core, which is designed for 816 bit microprocessor application. It can effectively reduce the code length compared with other processors with 810 / 16 bit architecture. In addition, the code to be restored is stored in a special memory W25X16, which has the advantage of very low power consumption and is very suitable for code download applications. The restore process is that LPC1114 controls the program in W25X16 to read out and write to CC2530, thus realizing the "one key restore" process. After a lot of practical tests, the test results show that the software and hardware systems in this paper meet the design requirements and improve the actual service life of the nodes.
