The technical noduses of the harmony loading system , such as multi - channel signal synchroniza - tion , signal phase modulating and frequency excursion control are discussed . the key steps and actualization details are also provided 同時,論文探討了協(xié)調(diào)加載控制系統(tǒng)的主要技術(shù)問題,如多余力、多通道相位協(xié)調(diào)和頻率漂移的控制等,并給出了系統(tǒng)實現(xiàn)的細節(jié)。
In addition , considering traffic security , operational efficiency and people ' s travel habits , the setting of signal phases must satisfy strong constraints , such as maximum and minimum green time , maximum queue length and smooth switch of signal timing parameters 并且,從交通安全、通行效率及人們出行習(xí)慣的角度考慮,信號燈相位的設(shè)置具有很強的約束,如最短和最長綠燈持續(xù)時間、最大排隊長度以及信號燈的配時參數(shù)要具有一定的穩(wěn)定性不能變化太劇烈等等。
