【摘要】：當(dāng)今社會(huì)經(jīng)濟(jì)迅猛發(fā)展,人們的收入水平大幅增加,生活節(jié)奏也越來越快,導(dǎo)致城市里汽車的數(shù)量也跟著迅速增加。但是與之配套的交通設(shè)施建設(shè)增長卻相對滯后,隨著時(shí)間的推移二者的矛盾會(huì)更加突出。由此造成的交通事故率也在上升。所以不能依靠傳統(tǒng)方法解決交通問題。必須結(jié)合現(xiàn)代的智能交通系統(tǒng)ITS來解決這個(gè)問題。而車位檢測系統(tǒng)是ITS的數(shù)據(jù)來源。本文設(shè)計(jì)了一種基于各向異性磁阻傳感器的無線車位檢測器,探討了利用磁阻傳感器進(jìn)行車位檢測的原理和車位檢測器和網(wǎng)關(guān)之間使用Zig Bee無線網(wǎng)絡(luò)技術(shù)來通信,驗(yàn)證了系統(tǒng)的穩(wěn)定性、低功耗。實(shí)現(xiàn)了車位檢測器各模塊的功能。完成數(shù)據(jù)的采集、處理,傳輸。具體所做的工作如下:(1)對當(dāng)前市場現(xiàn)有的檢測方法分析比較,提出了基于各向異性磁阻傳感器的無線車位檢測器,并介紹了當(dāng)前基于各向異性磁阻車輛檢測的研究狀況。(2)以微控制器CC2530和磁阻傳感器HMC5883L設(shè)計(jì)了硬件電路,并解釋說各硬件模塊的具體計(jì)算參數(shù)。(3)根據(jù)車輛進(jìn)出車位磁阻傳感器采集的數(shù)據(jù)分析,提出了依據(jù)模的變化率的車位檢測算法。(4)嵌入式軟件的設(shè)計(jì),根據(jù)系統(tǒng)各個(gè)功能,實(shí)現(xiàn)了相應(yīng)應(yīng)用程序模塊的設(shè)計(jì),并給出了相應(yīng)程序流程圖。該車位檢測系統(tǒng)已經(jīng)初步實(shí)現(xiàn)了所有功能,但是距離正真投入市場使用還有很大的差距,還有很多可以改進(jìn)的地方,還需要繼續(xù)研究和完善。
[Abstract]:With the rapid development of social economy, people's income level and life rhythm are increasing rapidly, which leads to a rapid increase in the number of cars in the city. However, the construction of transportation facilities is lagging behind. As time goes on, the conflict between the two becomes more prominent. The resulting traffic accident rate is also on the rise. Therefore, we cannot rely on traditional methods to solve the traffic problem. We must combine the modern intelligent transportation system (ITS) to solve this problem. In this paper, a wireless parking detector based on anisotropic magnetoresistive sensor is designed. The principle of using magnetoresistive sensors to detect parking spaces and the communication between parking space detectors and gateways using Zig Bee wireless network technology are discussed. The stability of the system is verified. Low power consumption. Realizes the function of each module of parking space detector. Completes the data collection, processing, transmission. The specific work done is as follows: 1) Analysis and comparison of the existing detection methods in the current market. A wireless parking position detector based on anisotropic magnetoresistive sensor is proposed, and the current research status of vehicle detection based on anisotropic magnetoresistive sensor is introduced. The hardware circuit is designed by microcontroller CC2530 and magnetoresistive sensor HMC5883L. According to the analysis of the data collected by the magnetoresistive sensor in and out of the parking space, this paper presents the design of the embedded software based on the changing rate of the mode-changing rate of the parking space, according to the various functions of the system. The design of the corresponding application program module is realized, and the corresponding program flow chart is given. All the functions of the parking space detection system have been preliminarily realized, but there is still a long way to go before it can be put into use in the market. There are still many areas that can be improved, and need to continue to study and improve.
