【摘要】：保證學生安全,研究智慧校車的安全監(jiān)管系統(tǒng)一直是一個重大難題,校車車載端的信息數據無法實時的準確掌控。但是隨著GPS技術、WIFI技術、RFID技術、4G網絡技術的成熟與運用,使校車車載端數據的采集變得可能。通過多技術的手段提高校車位置、學生射頻卡信息、校車內狀況、校車的速度等特征參數的采集精度,并經4G網絡傳輸至監(jiān)控中心,監(jiān)控中心根據實際參數做出遠端控制。本文首先介紹系統(tǒng)的設計性能指標,根據系統(tǒng)的總體的設計性能要求制定系統(tǒng)總體方案,運用模塊化的分組方式逐步推進方案的實時過程。其次,在硬件結構電路搭建平臺的基礎上進行軟件的設計,實現軟硬件的有效結合共同完成系統(tǒng)的功能需求。最后,系統(tǒng)的車載端和監(jiān)控端是系統(tǒng)的量大組成部分,在監(jiān)控端進行軟件的監(jiān)控,通過軟件平臺實時掌控車載端數據信息,并對車載端進行有效的控制,使校車在最佳的安全環(huán)境中運行。本設計在實驗室環(huán)境下進行測試分析,根據系統(tǒng)實現的性能指標對系統(tǒng)的軟硬的模塊分別進行測試,驗證軟硬件設計的正確性、合理性�？梢詫崿F校車的實時監(jiān)控,保證校車的人、車安全,具有很高的應用價值。
[Abstract]:To ensure the safety of students and to study the safety supervision system of intelligent school bus has been a major problem. The information and data on the on-board side of the school bus can not be accurately controlled in real time. However, with the maturity and application of GPS technology, WIFI technology, RFID technology and 4G network technology, it becomes possible to collect data from the on-board end of school bus. The acquisition accuracy of the characteristic parameters such as the location of the school bus, the information of the student radio frequency card, the state of the school bus, the speed of the school bus, and so on are improved by the means of multi-technology, and transmitted to the monitoring center through 4G network. The remote control is made by the monitoring center according to the actual parameters. This paper first introduces the design performance index of the system, according to the overall design performance requirements of the system to formulate the overall scheme of the system, using modular grouping approach to promote the real-time process of the scheme step by step. Secondly, the software is designed on the basis of the hardware structure and circuit platform to realize the effective combination of hardware and software to fulfill the functional requirements of the system. Finally, the on-board end and monitoring end of the system is a large part of the system, monitoring software in the monitoring end, real-time control of the on-board data information through the software platform, and effective control of the on-board end. Make the school bus run in the best safe environment. The design is tested and analyzed in the laboratory environment. According to the performance index of the system, the software and hardware modules are tested separately to verify the correctness and rationality of the software and hardware design. It can realize the real-time monitoring of school bus and ensure the safety of school bus. It has high application value.
