制動信號-
This system is exploited completely according to national standard of vehicle traveling data recorder, can implement all of the function of the national standard of vehicle traveling data recorder, including date, time, car speed, mileage, start time, stop time, driving time, over speed, overtime, alarm of over speed and overtime, status identify of ic card, and many kind of status of on - off signal, including on - off vehicle door, brake status, turn signal status, dipped headlight and high beam etc.
本系統就是完全依照汽車行駛記錄儀的國家標準而開發的，目標是實現國家標準中規定的所有汽車行駛記錄儀應該達到的功能指標，包括可靠記錄日期、時間、車速、行駛里程、開車時刻、停車時刻、行駛時間、超速時間、超時時間、超速超時告警、 ic卡身份識別等信息和車門開關、剎車狀態、方向燈狀態、近/遠光燈等各種開關信號的狀態的功能。 -
We also analyze the influence of the boundary condition 、 safety distance and deceleration probability to the traffic flow. finally, we propose an crossroad modle. this model is made up of one main road and one branches ： traffic with lights placed on the crossing, vehicles " breaking while running and turning to other direction while jamming. we investigate the velocity and flow of the model when the initial density, the brake and turning probabilities, the green to signal ratio are changed. then the reasons causing all the kinds of phenomena are analyzed
最後研究了周期性邊界條件下的十字路口的ca模型，該模型由一條主幹道和一條支道組成，在幹道與支道的交叉路口設置紅綠燈，車輛在運行中對突發事件發生反應的剎車，路口的車輛可以轉向等各種實際交通行為，並通過計算機模擬，研究模型在改變車輛的初始密度、剎車概率、轉向概率、紅綠燈信號的綠信比等各種情況下支、主幹道車輛的速度、流量的變化，並分析在各種情況下交通狀況的成因，提出改善交通的有效措施。 -
Secondllv in the 1 d random traffic flow model. the relation function between the correlation and the creation. disappearance. brake probabilities of the vehicles is presented. according to the statistical mechanical approach to the spatial correlation functions. the theoretical results agree with that of the computer simulation. thirdh. based on the bml model. a main - road traffic flow model with two speeds on two dimensions is designed. this model simulate the traffic situation of one main road and several branches in the cit traffic lights placed on the crossing. vehicles breaking ~ vhile running and turning to other direction while jamming. we investigate the ~ ' e1ocitv and flo ~ ~ of the model when the initial densitvthe brake and turning probabilities. the green to signal rati3. thc number of the branches and the period of the signal are changed. then the reasons causing all the kinds of phenomena are analvzed. finallv. we simulate the bml model using the method of lattice boltzmann which ~ vas brought out by liu mu - renand obtain the velocity - density graph similar to the previous result. the upper critical densiw above which there are oniv jamming configurations. and the lo ~ ver critical density below which there are only moving configurations are the same as before. the boltzmann function which is on the lattices shows the moving and jaxmning transition obviouslv. thus it proves the possibilit of this method on the traffic research
接著，建立了和研究了二維二速的主幹道模型，該模型模擬了城市交通中一條主幹道，多條支道的交通情況，在幹道與支道的交叉路口設置紅綠燈，車輛在運行中可以有對突發事件發生反應的剎車，在發生堵塞時，路口的車輛可考慮通過轉向來緩解交通等各種實際情況的發生，給出了車輛演化的演化方程，並通過計算機模擬，研究模型在改變車輛的初始密度、剎車概率、轉向概率、支道數、紅綠燈信號的綠信比、紅綠燈信號周期等各種情況下支、主幹道車輛的速度、流量的變化，並分析在各種情況下交通狀況的成因，提出改善交通的有效措施。最後，在劉慕仁提出的用格子boltzmann方法研究一維決定論交通流的思路下，將此法推廣到對二維bml模型的模擬上，得到了與用以往方法的研究結果相類似的速度-密度圖線，且車輛從運動相到堵塞相轉變的上下臨界密度是一致的，同時分別給出車輛在處于暢通相和堵塞相時， boltzmann函數在格子上的分佈情況，進一步驗證了此法的可行性。 -
Study on the pressure balance time affected by the different input signal will have very important meaning in theory and practice for the research and development on the performance test system of automobile brake valves. at the same time, it makes instructing reference to develop other test systems
不同輸入信號對壓力平衡時間的影響的研究，對汽車氣制動閥類件性能測試系統的開發只有重要的理論意義，同時也為其它測試系統的研製提供了有參考價值的實踐依據。
