Description
Technical field
The present invention relates to a kind of special automatic station announcer by GPS satellite position for train.
Background technology
The passenger in order to prevent to go past one's station, is concerned about that very the place ahead of train arrives at a station and arrival time in the travelling process.And present train to call out the stops be manually to report name of station by the attendant, so easy because of misrepresenting deliberately the station and calling out the stops and untimelyly bring inconvenience for numerous passengers, particularly during driving at night, the train broadcasting studio is off the air, attendant's name of just calling out the stops when train arrival only, not only inconvenient passenger knows that in time arrive at a station in the place ahead of train and arrival time information, produces stewed mood, and makes many passengers miss the time getting off.
Summary of the invention
The object of the present invention is to provide a kind of special automatic station announcer by GPS satellite position for train, it can make things convenient for the passenger to understand train arrival at any time, exactly and be about to the arrival station dot information, thereby prevents that the passenger from going past one's station, and alleviates passenger's anxiety.
Technical solution of the present invention is to constitute like this, it comprises GPS receiver module and receiving antenna thereof, the central processing unit that is connected input information with the GPS receiver module, the speech player and the display screen that are connected output information with central processing unit, and to the power supply of above-mentioned each parts power supply, described central processing unit comprises with the GPS receiver module and being connected to read the information read port of the arrival point GPS of train institute information, be used for the GPS information calculations is become the computing unit of the location information of train institute arrival point, be used to store the storage element of the pairing longitude and latitude identified region of each train bus stop name of station, each identified region that is used for location information that computing unit is calculated and storage unit stores compares to draw that train is arrived at a station or to be about to the comparison process unit of the name of station at arrival station, and be connected with display screen to broadcast or to show the relatively information output mouth of gained name of station of comparison process unit with speech player, described speech player and display screen are installed in every joint compartment.
Than prior art, the invention solves train when driving when driving at night (particularly) cause by manually calling out the stops misrepresent deliberately the station, the problem such as untimely of calling out the stops, it can forecast, really report the station that stops ahead of train operation automatically and accurately, it is not subjected to the influence of the late and temporary parking midway of train, for the passenger provides the service of round-the-clock automatic informing name of station, greatly made things convenient for the passenger, improved environment by bus, also brought better economic benefit for transportation by railroad.
Description of drawings
Fig. 1 is a principle of the invention block diagram.
Embodiment
Below in conjunction with specification drawings and specific embodiments content of the present invention is elaborated:
As shown in Figure 1, special automatic station announcer by GPS satellite position for train of the present invention comprises GPS receiver module and receiving antenna thereof, the central processing unit that is connected input information with the GPS receiver module, the speech player and the display screen that are connected output information with central processing unit, and to the power supply of above-mentioned each parts power supply, described central processing unit comprises with the GPS receiver module and being connected to read the information read port of the arrival point GPS of train institute information, be used for the GPS information calculations is become the computing unit of the location information of train institute arrival point, be used to store the storage element of the pairing longitude and latitude identified region of each train bus stop name of station, each identified region that is used for location information that computing unit is calculated and storage unit stores compares to draw that train is arrived at a station or to be about to the comparison process unit of the name of station at arrival station, and be connected with display screen to broadcast or to show the relatively information output mouth of gained name of station of comparison process unit with speech player, described speech player and display screen are installed in every joint compartment.
Described speech player preferably adopts MP3 format storage and plays, and utilizes the MP3 format storage and plays to make lamprophonia, tonequality good, and can download and the change voice content by the USB mouth.The power amplifier of speech player and output preferably directly insert original Public Address System on the train, and this part is finished the power amplification to voice, and can make full use of original resource, thereby cut down expenses.
Described display screen preferably adopts the LED Chinese characters display screen, perhaps also can show English simultaneously, thereby informs the next stop name of station and the name of station that arrives at a station with the mode that literal shows to the passenger, also can show public service ads or commercial advertisement at ordinary times.The every joint of this display screen compartment can be installed the two sides and watch to make things convenient for the passenger.Communication between every joint compartment can be adopted technology of infrared transmission, can save many troubles of laying communication cable between every joint compartment like this.
Central processor CPU partly is the core of total system, is used for storage system applications software and carry out these programs; Be responsible for reception, processing and calculating, obtain correct longitude and latitude and satellite time GPS information; Be responsible for download, storage, extraction and the broadcast of MP3 voice; Be responsible for control LED Chinese characters display screen and make it show the next stop name of station and the name of station etc. that arrives at a station, also have fault-tolerant and jamproof relevant design in the program.
GPS receiver module and receiving antenna thereof partly are responsible for receiving GPS information, and send the comparison process unit of central processing unit to.In view of the singularity of train, environment is very abominable, and particularly the high voltage of electric locomotive and high frequency interference are very big, will produce bigger influence to the reception of signal, so antenna should be selected the strong high-sensitive outdoor dedicated antenna of antijamming capability for use.
Can the direct supply of train be converted to the required power supply of system (relevant design that the various disturbing pulses of filtering are preferably arranged) to supply each parts work by power conversion part.
Principle of work of the present invention is described as follows:
At first, the longitude and latitude of each train bus stop on the way of collecting and the download of information such as each platform identified region that mark are on request stored in the storage element of central processing unit.
Secondly, under the commander of central processing unit, the GPS module constantly receives the data from satellite, analyzes and calculates, and draws the real-time longitude and latitude and the time of train.When the longitude and latitude that calculates falls into certain platform identified region, system will seek out this platform title automatically, start to arrive at a station broadcast and insert the original Public Address System of train; When the longitude and latitude that calculates exceeds certain platform identified region, system will seek out next stop platform title automatically, start the forecasting station broadcast and insert the original Public Address System of train.The LED Chinese characters display screen shows arrive at a station name of station or next stop name of station synchronously.
