【摘要】：近年來,國民經(jīng)濟(jì)飛速增長,科學(xué)技術(shù)特別是電子技術(shù)迅速進(jìn)步,這些客觀因素催生出各種新型的抄表系統(tǒng)。相對于傳統(tǒng)的抄表系統(tǒng),新型的抄表系統(tǒng)更加節(jié)省時間、節(jié)約人力、而且效率又高,是現(xiàn)代智能化住宅的首選抄表方式。本文結(jié)合實(shí)際應(yīng)用對其中一種新型的抄表系統(tǒng)——無線遠(yuǎn)程抄表系統(tǒng)的關(guān)鍵技術(shù)進(jìn)行了研究。本文的主要研究內(nèi)容如下:首先,介紹了各種自動抄表系統(tǒng)的開發(fā)過程以及發(fā)展?fàn)顩r,并介紹了燃?xì)獗頍o線遠(yuǎn)程抄表系統(tǒng)。針對不同的抄表環(huán)境,給出了兩種不同結(jié)構(gòu)形式的燃?xì)獗頍o線遠(yuǎn)程抄表系統(tǒng)方案——基于無線雙向燃?xì)獗矸桨负突跓o線采集器方案。并且,在單片機(jī)芯片STC89C52和無線數(shù)傳芯片CC1101的基礎(chǔ)上,設(shè)計了一款用于燃?xì)獗砼c手持機(jī)、燃?xì)獗砼c無線采集器、無線采集器與手持機(jī)之間相互通訊的無線數(shù)傳模塊,該模塊能夠滿足本文所設(shè)計的抄表系統(tǒng)中各個數(shù)據(jù)終端之間通訊的需求。其次,本文介紹了天線、電小天線以及天線阻抗匹配方面的基礎(chǔ)知識。在此基礎(chǔ)上,設(shè)計出了兩款能用于燃?xì)獗頍o線遠(yuǎn)程抄表系統(tǒng)的天線,分別是倒F螺旋天線和門型電小天線。這兩款天線都具有小型化的特點(diǎn),能夠安裝在燃?xì)獗肀須ぶ斜容^狹小的空間內(nèi)。同時,這兩款天線都通過短路點(diǎn)連接到地,可以有效防止在天線輻射器上面產(chǎn)生靜電,而靜電對燃?xì)獗韥碚f是一個很大的安全隱患。仿真與實(shí)測數(shù)據(jù)表明這兩款天線能夠滿足燃?xì)獗頍o線遠(yuǎn)程抄表系統(tǒng)無線通訊的要求。本文提出的無線遠(yuǎn)程抄表系統(tǒng)具有容易通信組網(wǎng)、頻點(diǎn)免申請以及資金需求量少等優(yōu)點(diǎn),能夠在很大程度上滿足人們對新型抄表系統(tǒng)的需求。
[Abstract]:In recent years, with the rapid growth of the national economy and the rapid progress of science and technology, especially electronic technology, these objective factors have given birth to various new meter reading systems. Compared with the traditional meter reading systems, the new type of meter reading systems save more time. Save manpower and be efficient, This paper studies the key technology of a new type of meter reading system-wireless remote meter reading system. The main contents of this paper are as follows: first, This paper introduces the development process and development status of various automatic meter reading systems, and introduces the gas meter wireless remote meter reading system. This paper presents two schemes of wireless remote meter reading system based on wireless bidirectional gas meter and wireless collector, which are based on single chip computer chip STC89C52 and wireless data transmission chip CC1101. A wireless data transmission module is designed for the communication between gas meter and handset, gas meter and wireless collector, wireless collector and handset. This module can meet the requirements of communication between different data terminals in the meter reading system designed in this paper. Secondly, this paper introduces the basic knowledge of antenna, small antenna and antenna impedance matching. Two antennas which can be used in gas meter wireless remote meter reading system are designed. They are inverted F helical antenna and gate type small antenna, both of which have the characteristics of miniaturization. Can be installed in a relatively small space in the gas meter case. At the same time, the two antennas are connected to the ground through short circuit points, which can effectively prevent static electricity generated on the antenna radiator. Static electricity is a great security hazard for gas meter. Simulation and measured data show that these two antennas can meet the requirements of wireless communication of gas meter wireless remote meter reading system. The wireless remote meter reading system proposed in this paper. Easy communication networking, The advantages of frequency exemption and less capital demand can meet the demand of the new meter reading system to a great extent.
