【摘要】：動(dòng)態(tài)稱重技術(shù)能夠顯著減少貨車稱重時(shí)間提高收費(fèi)站通行能力,然而受其模型所限,對(duì)于變速運(yùn)動(dòng)或車輪靜止于傳感器上的車輛則無(wú)法準(zhǔn)確進(jìn)行測(cè)量。針對(duì)以上問(wèn)題,以路面交互模型以及部分承載式動(dòng)態(tài)稱重模型為基礎(chǔ),提出了一種基于向量分割的部分承載動(dòng)態(tài)稱重模型。利用壓電石英傳感器結(jié)合該模型,以動(dòng)態(tài)傳感器稀疏陣列的形式構(gòu)建了一種4排直列式動(dòng)態(tài)稱重系統(tǒng)。在哈同高速哈爾濱東收費(fèi)站對(duì)系統(tǒng)進(jìn)行了低溫、定性與定量的測(cè)試。試驗(yàn)結(jié)果表明:該系統(tǒng)穩(wěn)定性好,在-28℃狀態(tài)下溫度漂移僅為0.5‰,響應(yīng)速度為0.2 s;在95%置信區(qū)間內(nèi),精確度為±3%以內(nèi),特別是能夠解決動(dòng)態(tài)稱重中"二次起停"的問(wèn)題。該系統(tǒng)能夠?yàn)橹剌d交通智能化管理提供一定的支持。
[Abstract]:Dynamic weighing technology can significantly reduce the loading time of freight cars and improve the capacity of toll stations. However, due to the limitation of its model, it is impossible to accurately measure vehicles with variable speed motion or stationary wheels on the sensor. Aiming at the above problems, a dynamic weighing model based on vector partitioning is proposed based on the pavement interaction model and the partial load-bearing dynamic weighing model. Based on the piezoelectric quartz sensor and the model, a 4-row linear dynamic weighing system is constructed in the form of sparse array of dynamic sensors. The low temperature, qualitative and quantitative tests of the system were carried out at Harbin East Toll Station. The test results show that the system has good stability, the temperature drift is only 0.5 鈥，
