公交车报站器原理

公交车报站器原理

公交车报站器原理
公交车报站器,又称为公交车站播报系统,是一种通过电子设备实现自动报站功能的系统。

它的原理主要基于GPS定位技术和语音合成技术。

首先,公交车报站器通过GPS接收机接收GPS工作卫星的导航信息,从而解算出车辆的经纬度等位置信息。

这些信息被实时传输到控制中心,经过处理后与预设的站点坐标进行比对,从而判断公交车与各个站点之间的距离和相对位置。

当公交车驶入站点一定距离范围内时,报站器会自动触发语音播报功能,通过语音合成技术将预设的语音内容播放出来,向乘客播报站点信息。

这些语音内容可以是中文、英文或其他语言,以满足不同地区和乘客的需求。

除了自动报站功能,公交车报站器还具备其他辅助功能。

例如,它可以与公交车的调度系统相连,实时上传车辆的位置和状态信息,帮助调度员更好地管理车辆和调整运营计划。

此外,报站器还可以与车载显示屏相连,将站点信息和广告等内容显示在显示屏上,为乘客提供更加丰富的信息。

公交车报站器的应用不仅提高了公交车的运营效率和服务质量,也提升了乘客的出行体验。

它能够自动、准确地播报站点信息,避免了人工报站可能出现的误差和延误。

此外,报站器还可以为乘客提供其他有用的信息,如车辆到站时间、天气情况等,方便乘客更好地安排行程。

总之,公交车报站器是现代科技在公共交通领域的应用之一,它的工作原理基于GPS定位技术和语音合成技术,通过自动播报站点信息和其他辅助功能,提高了公交车的运营效率和服务质量,为乘客提供了更加便捷和舒适的出行体验。

FRID技术的简介和所有资料最全

本节介绍一种利用RFID技术与单片机技术相结合,实现公交车站的自动识别与自动报站的方式。

最近几年来,随着信息技术的快速进展,城市公交车的治理方式也发生了专门大转变,许多城市都由原先靠售票人员售票、报站的方式改成实行无人售票和自动报站系统。

目前最经常使用的自动报站方式是由驾驶员操纵的报站系统。

通常的工作进程是:车辆进站前预报一次车站,车停稳开门时报一次车站,车辆起步后,报一次站,车辆离开车站再预报下一个车站,如此循环。

每次报站时都需要由驾驶员对报站器进行操作,而在车辆起动与进站时,往往是路面情形最复杂的时候,驾驶员既要对行驶中的汽车进行启动或制动等操作,同时还要兼顾报站系统的操作,给行驶中的车辆带来必然的平安隐患。

为了解决那个问题,有人设计了一种自动报站的方式,用车辆的行驶特点,如起步后行驶的距离、开关门的信号、起步和进站打转向灯的方式综合起来判定车辆的起步、行驶、进站状态。

这种方式做到了必然程度上的自动报站,但这种方式要求驾驶员必然要按驾驶标准操作,若是驾驶员操作不标准或碰到特殊情形时紧急处置,例如半途停车等,就有可能引发报站错误。

同时,对行驶距离的判定需要加装额外的传感器或连接汽车原有的计程电路,技术安装比较复杂。

本节提供了一种基于RFID技术的公交车自动识别车站、自动报站的技术方案。

在识别车站、自动报站的进程中,完全不需要驾驶员进行操作,减轻了驾驶员的负担,增加了车辆运行的平安性。

1 系统硬件结构系统整体硬件结构如图所示。

(1)系统采纳单片机89C52作CPU,同时接收遥控接收模块解码RFID后的数字信号和车门传感器送来的信号,用软件实现车站的自动判定识别。

并依照识别的信息操纵报站装置自动报站,没必要人工操作。

车载机硬件原理如图所示。

89C52的P0口接PT2272解码器模块,P1口操纵扩音系统,P2口接数码显示,P3口接录音芯片。

还连接了常规的键盘、显示和串行EEPROM存储器AT24C01等。

现在公交车上普遍使用的人工按键报站会出现报站不准确(由于司机在操作报站系统时经常会按错键或忘记按键,而且在调整系统时会连续报出几个站点,让不熟悉路线站点的乘客不知所措)。

并且每次报站时都需要由驾驶员对报站器进行操作,而在车辆起动与进站时,往往是路面情况最复杂的时候,驾驶员既要对行驶中的汽车进行起动或制动等操作,同时还要兼顾报站系统的操作,给行驶中的车辆带来一定的安全隐患。

虽然现在已经有些大城市的某些公交车上已经采用GPS定位系统自动报站,但其昂贵的成本,难以实现普及,特别是一些中小城市难以负担。

The research of RFID technology and the bus stops automatically What is the RFID?RFID is the abbreviation for Radio Frequency Identification, called electronics label .RFID recognition is a non-contact automatic identification technology, RFID signal through its automatic target recognition and access to relevant data, identify work without manual intervention, it can work in various environments. RFID technology can identify high-speed moving objects and can identify multiple tags, the operation is fast and convenient.RFID is a technology which uses radio communication between tags and readers to automatically identify the locations of items. In a networked environment of RFID readers, enormous data are generated from the proliferation of RFID readers. The raw data generated from the readers cannot be directly used by the application because it consists of enormous volume of data duplication, false positive, and false negative. Thus, the RFID data repositories must cope with a number of quality issues. These data quality issues include data redundancy, false positive, and false negative. Poor data quality has adverse effects at the operational, tactical, and strategic levels of an organization. This is especially true in the healthcare field where cost pressures and the desire to improve patient care drive efforts to integrate and clean organizational data.What is the basic component of RFID?The most basic RFID system consists of three parts:Tag:Tag consists of components and chips, each Tag has only electronic coding, adhere to the object for identifiering target;Reader:read (sometimes also can write) label information equipment,it canbe designed for portable or fixed;Antenna: Transmit radio frequency signals between in the label and reader. What is the basic principle of RFID technology ?The basic principle of RFID technology is not complex: Label into the field, Receive radio frequency signals from reader collision, with all the energy stored in a chip of the product information (passive tag, there is no source label or labels ), Oractively to send a frequency signals (active tag and to label or labels );to read information and understanding of the decoder after the central information systems to carry out the relevant data processing.Basic working process of the RFID systemThe RFID system of basic workflow is: reader through the antenna send certain frequencies of RFID signals, when the RFID card to enter the antenna working area induced current, RF cards gain energy to be activated,RF cards will own coding information through the card built-in transmitting antenna send out, System receiving aerial from RF card from the carrier signal, the antenna of a regulator to the reader, the reader to receive a signal and demodulates and decodes to the system to deal with the relevant ; the main system based on logic, determine the legality of smart cards, in different settings make the appropriate treatment and control signals control and direction of movement. In the coupling between inductors and electromagnetic way , communication process (FDX, HDX, SEQ)、From RF card to the reader of data transmission of the load method (modulation, reverse scattering, high time harmonics) and frequency, from the contact method transmission a fundamental difference, but all the reader in principle, and the decision of the design structures are very similar. all the reader is a simple matter of high frequency and control unit two basic module. high frequency interface includes both transmitters and receivers, its functions include: to produce high-frequency transmit power to start and provide RF card energy. To launch signal used to send data to RF cards, Receive and demodulation of high frequency signals from RF cards. Different RFID system with some difference frequency interface design, the system frequency inductive coupling interface diagram shown.quartzoscillatormodulator output stage amplifier antband passamplifier output stage TXD RXDReaders of the control unit features include: communicate with the application software, Application software and to execute the order of radio frequencies ;control and communication from the principle of the lord;signal of the decoding. to some specific systems are the collision, the algorithm to RF card reader, and to the transfer of data encryption and decryption, as well as on radio frequencies and the reader's authentication for an additional function.The RFID system is a key and distance of the parameters. At present, the price of long-distance RFID system is very expensive, thus to improve their reading for distance of the method is very important. Influence factors of distance and RF card reader, including antenna working frequency of RF output power, reader's reception sensitivity, RF card power, antenna and the resonant circuit Q value, antenna, RF card reader and the direction of the coupling, and RF card itself of energy and send information energy etc. Most of the system of writing is read and write different, read the distance is about 40% to 80%.The application of RFID system(1)Application in healthcareLocalization of patients, staff, supplies and equipment is very important for healthcare centers to improve service, save costs, and reduce risks. Pilot projects in hospitals demonstrate that RFID localization is a valuable approach. LANDMARC, an RFID localization system (Li et al. 2004), has been applied to facilitate the management of hospitals and other organizations in case of emergency. The system operates at the frequency of 308MHz, and is composed of active tags, landmark tags, readers, and communication devices. The position of an active tag can be determined by comparing the signal strength detected and the signal strengths of landmark tags. Using this system to monitor the infectious patients can reduce the number of healthcare professionals and ensure timely response for emergency. Meanwhile, integrated business systems and services (IBSS) announced a success pilot study for using RFID technology to locate assets and personnel at a large healthcare facility in Chicago (O’Connor 2005). Emory Healthcare successfu lly deployed 2.45GHz active RFID devices to track infusion pumps and other high-value equipment to improve asset management and utilization (O’Connor 2007). Note that the last two healthcareapplications do not employ localization algorithms, instead, they estimate the object location based on the detection from a nearby sensor. The accuracy of location can be improved by integrating localization algorithms.(2)Application in construction material managementTracking the location of construction resources enables effortless progress monitoring and supports real-time sensing of construction status. Jaselskis and ElMisalami (2003) developed a prototype RFID tracking system for improving the material procurement process on a construction site. Furthermore, Song et al. (2007) developed a method to locate materials on construction sites. The method requires a eld supervisor be equipped with an RFID reader and a GPS receiver. The GPS receiver provides the absolute position information of the supervisor, while the position of the material relative to the supervisor can be determined from the multiple communications between the reader and the tag attached to the materials.The bus is automatically stops the background and significanceThe people of car out for provides convenient service, while the bus stops directly affect the quality of the service. Traditional stops by the crew artificially, and in this way because of its poor and working intensity effect is too great, in many big ci ties have been eliminated. In recent years, with the development of science and technology progress and microcomputer technology in many fields has been widely used. In the acoustic field, with various pronunciation chip microcomputer technology ,can complete combined speech synthesis technology, makes the car stops controller is realized for citizens becomes possible, and thus provide a more personalized service. In view of the traditional bus stops system deficiency, combined with the use of public transport vehicle characteristics and practical operating environment, the design of a single-chip microcomputer control bus stops system automatically.The bus stops the design of automatic device is mainly to compensate for changing the traditional voice stops device must have driver control can work backward way, pitted ,automatic station broadcasts six-foot-tall service term for the public and provide mor e humanized more perfect service.The characteristics of the system and advantageThis system greatly improve the accuracy of bus stops, and reliability.Improving the service quality of the bus system. Promote the city economic developm ent and harmonious development of traffic changes. Made up for changing thetraditional voice stops device must have driver control can work means, in the bus sto ps behind when the station broadcasts, automatic six-foot-tall service term for the public and provide more humanized more perfect service.The present status of intelligent city bus stopsIn the process of informationization in China, a city's public transportation industry becomes the measuring level and a reference point of urban civilization for informationization as an important window. The developing level of public transportation not only represents the image of a city, but also relates with everyone in the city. The Broadcasting System for Bus well embodies services and careness for passengers.At present, the Broadcasting System installed on the bus is still operated manually with push-button, which may have potential safety hazard. In order to control the speed of each bus, Public Transport Company has to send a worker to record the time when the buses in the same line arrive at the station. The television installed on each bus transmits the same programme all day, which hardly satisfies every passenger. So the cost of advertisements broadcasted on the TV can' t drop. Based on the studies on present public transportation system, the dissertation aims to design the multi-function automatic broadcasting system for bus, which technologically combines ARM with RFID. RFID is a kind of non-contact automatic identification technology; it identifies and obtains the corresponding data automatically through the RF signal. This system can not only realize the basic function of automatic broadcasting but also do attendance checking for buses’arrival time as well. At the same time, it has realized Play AD at Real-Space-a new kind of advertising on the bus, thus enhencing the informationization level of public transpotation industry,reducing management costs, satisfing most passangers favors, improving the serving and operating level of automatic broadcasting and then makes the city more beautiful.ConclusionRFID plays an essential role in all the subdomains of the applications inhealthcare applications. The effectiveness in cleaning the RFID data in healthcare sectors remains a concern, even though a number of literary works are available.To a maximum, the dirty data that are read may even leads to patients’ death. The errors need to be cleansed in an effective manner before they are subjected to warehousing. Current solutions to correct missed readings usually use time window filtering. A serious issue is that a single static window size cannot compensate for missed readings while capturing the dynamics of tag motion. An adaptive time window filtering cannot deal with the condition that tags are always moving.In this paper, we have proposed algorithms to clean the anomalies false positive, missed readings, and duplications. It is decided to record all the values associated with each tag event for future reference otherwise too much valid data will be lost.Finally, the management can analyze the data and filter by applying business rules based on the requirement. The proposed algorithms predict and clean the anomalies based on the integration of middleware and deferred. Our experimental result proved that our algorithms predicts and removes the anomalies in an effective manner compared to the existing works. Thus, it will pave the way for an effective means of data warehousing system that will keep the RFID data safe for future mining.RFID技术及公交自动报站的研究RFID是什么?RFID射频识别的缩写,被称为电子标签。
