【摘要】：許多年來,我國公路上行駛的汽車普遍存在超載現(xiàn)象,在有些地方,無論貨車還是客車都有程度不一的超載行為。這會(huì)給正常的運(yùn)輸市場、安全駕駛及汽車的生產(chǎn)銷售帶來很大的危害。現(xiàn)在,我國治理汽車超載主要是在道路上設(shè)立檢查站,對(duì)過往車輛進(jìn)行抽查稱重,因此稱重設(shè)備的好壞就成為其中的關(guān)鍵。目前,稱重設(shè)備主要有汽車輪重稱重儀、汽車軸重儀和電子地磅等。 目前市場上銷售的汽車稱重儀器普遍存在價(jià)格高、體積大、安裝麻煩、效率低和動(dòng)態(tài)稱重不準(zhǔn)確等缺陷。本課題將要設(shè)計(jì)一種簡單的汽車載重測量設(shè)備,能夠?qū)崿F(xiàn)靜態(tài)和動(dòng)態(tài)兩種測量方式,以有效控制目前的汽車超載現(xiàn)象。 本課題采用電容傳感器、單片機(jī)和無線傳輸芯片設(shè)計(jì)出一種汽車稱重裝置。該裝置通過電容傳感器采集數(shù)據(jù),經(jīng)模數(shù)轉(zhuǎn)換后傳給單片機(jī),駕駛員可以通過顯示模塊直接觀察,也可以利用無線收發(fā)芯片nRF401進(jìn)行無線數(shù)據(jù)傳輸,交通稽查人員通過手持裝置就能夠獲得汽車的實(shí)時(shí)載荷信息,可以方便快捷的判斷出車輛是否超載,提高了工作效率,從而能更有效治理超載行為。本課題從載荷信息采集處理、數(shù)據(jù)轉(zhuǎn)換、單片機(jī)控制、無線通信、與PC機(jī)串口通信和信息顯示等幾方面入手,介紹了稱重系統(tǒng)各組成部分的硬件和軟件設(shè)計(jì)方案。
[Abstract]:Over the years, overloading has been a common phenomenon in China's highways. In some places, both trucks and buses have overloading behaviors of varying degrees. This will do great harm to the normal transportation market, safe driving and the production and sale of automobiles. At present, weighing equipments mainly include automobile wheel weighing apparatus, automobile axle weighing apparatus and electronic ground weighing apparatus.
At present, the automobile weighing instruments on the market generally have the defects of high price, large volume, troublesome installation, low efficiency and inaccurate dynamic weighing.
In this paper, a kind of automobile weighing device is designed by using capacitance sensor, single chip microcomputer and wireless transmission chip. The device collects data from capacitance sensor and transmits it to single chip microcomputer after analog-to-digital conversion. The driver can observe directly by display module, and can also transmit data by wireless transceiver chip nRF401. The real-time load information of the vehicle can be obtained by the handheld device, which can judge whether the vehicle is overloaded or not, improve work efficiency, and thus more effectively control the overload behavior. This paper introduces the hardware and software design of the components of the weighing system.
