In the process of communication, adopt the radiowave of the 433MHz communication frequency band among the ISM as the communication carrier wave, use and work in the wireless module of this frequency range as communication module.All embed such wireless module every public transport POS inside, and give fixing wireless addressing address of each module assignment.At the place, bus station, an acquisition terminal is set, acquisition terminal is connected with the PC main frame of a special use.The PC end can be stored in database with data with corresponding process software, and the webmaster that also data communication device can be crossed appointment connects the clearing backstage that sends to public transport company, is used for the clearing of data.
After bus stops, the swipe the card collection of activation data of attendant in standing or driver, the wireless module of POS machine inside is opened, the wireless acquisition module of server end finds this to open the POS machine of wireless telecommunications by the mode of addressing, through shake hands early stage, after the authentication, just the record of swiping the card in the bus POS machine can be gathered automatically, realize simultaneously the synchronous of time, the operations such as blacklist download.After collection was finished, corresponding bus POS withdrawed from capture program automatically, the wireless module autoshutdown, and assurance does not affect other public transport POS data acquisition.
The realization of public transport POS end wireless telecommunications: with public transport POS machine with circuit wired or the infrared communication part remove, wireless communication module with a 433MHz substitutes, and can use RS232 or SPI interface that public transport POS is connected with wireless module.The wire casing of the antenna of wireless communication module below POS picks out, and is fixed to around the POS machine.Because antenna has suction-operated, be easy to be adsorbed onto on the object of metal material on every side.
The realization of collector end wireless telecommunications: the collector end is a product that designs separately, is connected with PC.Have real-time clock, can preserve the files such as data, blacklist of collection, and have management control function.Antenna adopts the omnidirectional antenna of large gain, uses coaxial cable antenna to be received the higher positions such as roof.
Public transport POS addressing code Design realizes: for each bus, according to the factor of the othernesses such as public bus network, the number-plate number, give unique numbering.Address field has the 16bit byte.Maximum has 65535 addresses to distribute, and satisfies existing bus management fully.Because the uniqueness of coding also can guarantee the data of the bus of non-our station are not gathered.Guarantee the unitarity of management.
Also can carry out wireless telecommunications Redundancy Design: ISM (Industrial Scientific Medical) frequency range, be defined by Radiocommunication Bureau of International Telecommunications Union.This frequency range mainly is open to industry, science, medical science, and three principal organ use, and belong to Free License, namely need not authorization, only need to observe certain emissive power (generally being lower than 1W), and do not cause interference to get final product to other frequency range.Since around may also can be temporarily or forever have 433MHz or near the interference source of frequency, need to adopt the measures such as anti-interference, encryption at the radiowave of communication, guarantee the effectively correct and reliable of data.In the realization of reality, at first the data Manchester's cde mode that will send is encoded, although the rate reduction of wireless telecommunications, the anti-interference of overall data is greatly improved.Simultaneously for the packet of each transmission, all distributed the numbering of progressively increasing, when receiving end was found to have data sequence number not corresponding, re-transmission that can request msg reduced indivedual packet losses to the impact of whole communication.Adopt the mode of parcel data transmission, when noisy on every side the time, relatively can reduce much with large bag data the impact of parcel data, make communication more stable.Increase handshake sequence at the wireless data front end in addition, carried out the work of input and address pairing by judging specific handshake sequence, masked the undesired signal data.
The design of station collector antenna: in order to guarantee that the collection success ratio of wireless data is higher AT STATION, the common reasonable omnidirectional antenna of selectivity, adopt high other power delivery and reception module of a level, generally antenna installation is arrived higher position, reduce as far as possible the interference of hamper between the antenna that gathers antenna and public transport POS.Because the public transport vehicle body is metal mostly, signal itself there is certain decay, by above-mentioned mode, can greatly reduce some unnecessary signal attenuations, guarantee the reliability of wireless data communication.
