【摘要】：隨著城市的快速發(fā)展,現(xiàn)代智能交通信號(hào)控制系統(tǒng)要求信號(hào)機(jī)中各通信模塊的設(shè)計(jì)具有強(qiáng)大的可擴(kuò)充性,以解決逐步完善的智能交通信號(hào)控制系統(tǒng)的需要。在這種解決方案中,與信號(hào)機(jī)本地主控制單元通訊的模塊及設(shè)備很多,且信號(hào)機(jī)內(nèi)部各板卡之間也需要大量、頻繁的數(shù)據(jù)交換。一般來(lái)說(shuō),這需要功能強(qiáng)大、資源豐富的嵌入式系統(tǒng)來(lái)實(shí)現(xiàn),這必然導(dǎo)致高昂的設(shè)備成本,所以采取這樣大型的交通信號(hào)控制系統(tǒng)對(duì)于經(jīng)濟(jì)實(shí)力較為薄弱的中小規(guī)模城市是不可能的。但是城市的加速發(fā)展導(dǎo)致以往價(jià)格較低的設(shè)備系統(tǒng)已經(jīng)不能滿足現(xiàn)在的交通壓力,于是全面更新信號(hào)機(jī)設(shè)備,建立功能完善、智能性較強(qiáng)且適合中小規(guī)模城市交通特點(diǎn)的交通信號(hào)控制系統(tǒng)已然成為一種必須,因此針對(duì)中小城市的交通信號(hào)控制系統(tǒng)進(jìn)行研究與設(shè)計(jì)有著很強(qiáng)的必要性和重要性。 本論文圍繞在針對(duì)中小城市的交通信號(hào)控制系統(tǒng)進(jìn)行的研究與設(shè)計(jì)這一項(xiàng)目中展開(kāi)研究,主要工作有如下幾點(diǎn)： 第一,以往大多中小規(guī)模城市采用的都是單機(jī)運(yùn)行的信號(hào)機(jī),其智能性極差,此次研究與設(shè)計(jì)不但擴(kuò)展了信號(hào)機(jī)的通信模式如TCP/IP通信、232通信、485通信以及USB通信,并設(shè)計(jì)了有著地方特色的行人觸動(dòng)按鈕。簡(jiǎn)言之,通信模式的擴(kuò)展和新增的功能模塊極大地增強(qiáng)了交通信號(hào)控制系統(tǒng)的智能性。 第二,設(shè)計(jì)實(shí)現(xiàn)了自己的通訊軟件,其優(yōu)點(diǎn)在于用51語(yǔ)言和匯編語(yǔ)言混合編制實(shí)現(xiàn)了新增的通信模式和應(yīng)用。這樣在增強(qiáng)軟件智能性的同時(shí)又提高了軟件的運(yùn)行速度。 第三,研究參考了交通信號(hào)控制機(jī)與上位機(jī)之間數(shù)據(jù)通訊的國(guó)標(biāo)協(xié)議,并結(jié)合中小規(guī)模城市如忻州當(dāng)?shù)貙?shí)際的交通狀況及特點(diǎn),擬定了適合像忻州這樣中小規(guī)模城市交通特點(diǎn)的交通信號(hào)控制機(jī)與上位機(jī)之間的數(shù)據(jù)通訊協(xié)議。 第四,研發(fā)出了近百臺(tái)交通信號(hào)控制機(jī),目前,這些信號(hào)機(jī)已經(jīng)安放在了忻州市7451工程新建的所有路段,試行效果非常理想,確實(shí)緩解了忻州市交通道路的緊張形勢(shì),徹底解決了當(dāng)?shù)氐慕煌▔毫Α?br/>[Abstract]:With the rapid development of the city, the modern intelligent traffic signal control system requires the design of each communication module in the signal generator to be powerful and expandable. In this solution, there are a lot of modules and equipments to communicate with the local main control unit of the signal generator, and a large number of boards and cards within the signal machine also need to meet the needs of the gradual improvement of the intelligent traffic signal control system. Frequent data exchange. In general, this requires powerful, resource-rich embedded systems to achieve, which will inevitably lead to high equipment costs. Therefore, it is impossible to adopt such a large traffic signal control system for small and medium-sized cities with relatively weak economic strength. However, the acceleration of urban development has led to the past low price equipment system has been unable to meet the present. Traffic pressure. Therefore, it is necessary to update the signal equipment and establish a traffic signal control system with perfect function, strong intelligence and suitable for the traffic characteristics of small and medium-sized cities. Therefore, it is necessary and important to study and design the traffic signal control system in small and medium cities. This thesis focuses on the research and design of traffic signal control system in small and medium-sized cities. The main work is as follows: First, most of the small and medium-sized cities used in the past are single-machine running signal, its intelligence is extremely poor, this research and design not only extended the communication mode of the signal machine such as TCP/IP communication. 232 communication communication and USB communication, and designed a pedestrian button with local characteristics. In short. The expansion of communication mode and new function modules greatly enhance the intelligence of traffic signal control system. Second, the design and implementation of their own communication software. The advantage is that the new communication mode and application are realized with the combination of 51 language and assembly language, which not only enhances the intelligence of the software, but also improves the running speed of the software. Thirdly, the study refers to the national standard protocol of data communication between the traffic signal control machine and the upper computer, and combines the actual traffic situation and characteristics of small and medium-sized cities such as Xinzhou. The data communication protocol between the traffic signal control computer and the upper computer which is suitable for the traffic characteristics of small and medium-sized cities such as Xinzhou is worked out. In 4th, nearly 100 traffic signal control machines were developed. At present, these signal machines have been installed in all new sections of Xinzhou 7451 project, and the trial results are very satisfactory. It really alleviated the tense situation of Xinzhou traffic road and solved the local traffic pressure thoroughly.
