【摘要】：中國經(jīng)濟的高速發(fā)展使我國私家車數(shù)量迅速增長。道路擁堵、泊車困難的問題也成為了制約城市進一步發(fā)展最大的阻礙，如何提高停車位的使用率以解決泊車難的情況是一個亟需解決的問題。結(jié)合這一情況提出基于地磁傳感器的智能車位管理系統(tǒng)的設(shè)計方法。 系統(tǒng)的硬件由基于地磁傳感器的無線數(shù)據(jù)采集節(jié)點、數(shù)據(jù)中繼節(jié)點、數(shù)據(jù)集中器及上位機組成，數(shù)據(jù)采集終端采集停車位地磁場的信號；數(shù)據(jù)中繼節(jié)點將接收到的數(shù)據(jù)采集終端的數(shù)據(jù)上傳至數(shù)據(jù)集中器，再通過數(shù)據(jù)集中器通過串口發(fā)送至上位機，，最終通過上位機對車位信息進行管理及顯示。 數(shù)據(jù)采集終端采用低功耗設(shè)計，利用電池供電，通過選用美國德州儀器（TI）公司的低功耗無線數(shù)據(jù)傳輸模塊CC2500及超低功耗MSP430單片機，地磁傳感器使用Honeywell公司的HMC5883L低功耗地磁傳感器，在滿足系統(tǒng)工作的同時能最大限度的降低系統(tǒng)的功耗。通過測試，系統(tǒng)功耗約為0.7mW，使用常規(guī)3.7V鋰亞電池供電，即可讓系統(tǒng)工作4年以上。 通過模擬測試，對停車場內(nèi)常見的三種停車情況進行分析，可以得知，地磁傳感器均可以有效的將車位的占用情況判斷出來，檢測準確率較高，能達到97%以上。系統(tǒng)的實際測試結(jié)果表明，基于地磁傳感器的智能車位管理系統(tǒng)能夠滿足停車場車位空閑狀態(tài)實時檢測的需要。
[Abstract]:The rapid development of Chinese economy makes the number of private cars increase rapidly. The problem of road congestion and parking difficulties has become the biggest obstacle to the further development of the city. How to improve the utilization rate of parking spaces to solve the parking difficulties is a problem that needs to be solved. The design method of intelligent parking space management system based on geomagnetic sensor is presented. The hardware of the system is composed of wireless data acquisition node based on geomagnetic sensor, data relay node, data concentrator and upper computer. The data acquisition terminal collects the signal of geomagnetic field of parking space. The data relay node uploads the data from the received data acquisition terminal to the data concentrator, then sends the data to the upper computer through the serial port through the data concentrator, and finally manages and displays the parking space information through the upper computer. The data acquisition terminal uses low power design, battery power supply, low power wireless data transmission module CC2500 and ultra-low power MSP430 single chip microcomputer. The geomagnetic sensor uses Honeywell's HMC5883L low-power geomagnetic sensor, which can reduce the power consumption of the system at the same time. The test results show that the power consumption of the system is about 0.7 MW, and the system can be operated for more than 4 years by using the conventional 3.7V lithium subbattery. Through the simulation test and the analysis of the three common parking conditions in the parking lot, it can be found that the geomagnetic sensor can effectively judge the occupation of the parking space, and the detection accuracy is high, which can reach more than 97%. The practical test results show that the intelligent parking space management system based on geomagnetic sensor can meet the need of real-time detection of parking space idle state.
