Description
Technical field
The present invention relates to a kind of automatic bus stop announcing method and station reporting instruments.
Background technique
Currently, most of city bus has all popularized unmanned automatic ticketing vehicle, it is equipped with compared to pervious public transport
For full-time ticket seller, the casting of arriving at a station of present city bus has switched to electronic speech and has called out the stops from manually calling out the stops, and reduces public affairs
The manpower of friendship system occupies, and reduces operation cost.Current sound broadcast system is divided into two kinds, calls out the stops and reports manually automatically
It stands.The first is the casting of driver's manual key, is currently the most common sound broadcast mode.Disadvantage is also apparent, needs
Driver's frequent operation, the leakage station rate rate that reports an error is objectively higher, and when while often pulling in is that surface conditions are complex, this
When driver need to divert one's attention key, certain hidden danger is brought to traffic safety.
Another then be the automatic stop reporter based on GPS positioning, principle is the longitude and latitude for being previously stored each website
Then information constantly compares in practical driving conditions, just trigger voice broadcast when triggering in prescribed limit.At present should
The station reporting instrument popularization degree of type is not high, because its disadvantage is obvious.
Public bus network usually divides uplink and downlink, and it is different to broadcast voice.Same website there are two the road both sides,
Latitude and longitude information is very close, is easy to mix up when relatively, is extremely easy to appear the public transport report for being in uplink downlink
The voice of line.So just need to the quite high precision of positioning requirements to GPS, improve cost.
Public transportation automatic station-reporting mostly uses greatly sequence to call out the stops at present, once centre is failed to report, next station name is all
It will report an error.
In the case that only a few bus need to have to slightly offset from route, this sequence broadcast voice will also be caused out
It is wrong.
Summary of the invention
The present invention will overcome the disadvantages mentioned above of the prior art, provide a kind of automatic bus stop announcing side based on GPS positioning
Method and its station reporting instrument.
The present invention is directed to improve current driver the inconvenience of voice system bring and hidden danger is manually operated, bus is improved certainly
The reliability of dynamic scheme of calling out the stops, it is feature-rich, there is arrival information animatic projector, the voice broadcast of non-ordering type is automatic to differentiate
Uplink and downlink route and overspeed detection etc. function bring driving to facilitate for public transit system.
Automatic bus stop announcing method based on GPS positioning of the invention, comprising the following steps:
Step 1. stores the latitude and longitude information of inception point terminus and intermediate each website first, respectively to each website
Voice carries out uplink and downlink respectively and records and store, and makes the speech database of uplink and the speech database of downgoing line.
Step 2. collects GPS longitude and latitude positional information, compares when driving starts with whole story station location information distance, and judgement is worked as
Preceding harness belongs to uplink route or downlink route, specifically includes:
Judge whether 21. collecting GPS latitude and longitude information and comparing far from the starting station；
Judge whether 22. collecting GPS latitude and longitude information and comparing close to terminus；
23. judging that current line belongs to uplink route or downlink route, and call corresponding speech database.
Step 3. collects GPS longitude and latitude positional information, is matched with site location information, judges whether to pull in, specifically
Include:
31. receiving current bus latitude and longitude information；
32. recalling a nearest website of distance from pre-stored latitude and longitude information to be matched；
33. distance is greater than L, step 32 is returned to, L is website triggering speech range；
34. distance is less than L, the site information, and caption playing are broadcasted；
Step 4. carries out voice broadcast according to matching result, triggers captions rolling.
Speed is monitored in step 5. driving conditions, judges whether bus is more than setting speed value, if hypervelocity
Deceleration suggestion voice is broadcasted, warning driver reduces bus speed.
51. collecting the bus positional information of first time；
52. collecting the bus positional information of the second time
53. calculating bus in the distance of the position of first time and the second time and obtaining current speed divided by time interval
Angle value；
54. by current velocity amplitude compared with setting speed value；
If returning to step 51 55. velocity amplitude is less than setting speed value at present；
If broadcasting suggestion voice 56. velocity amplitude is greater than setting speed value at present and returning to step 51.
Implement the station reporting instrument of the automatic bus stop announcing method of the invention based on GPS positioning, including as data processing
With the single-chip microcontroller of control centre, single-chip microcontroller connects USB power source, GPS module, voice playing module, LCD MODULE；GPS mould
The location information of block acquisition bus is simultaneously transferred to single-chip microcontroller；After the location information of single-chip microcontroller analysis processing bus, transmission refers to
It enables to voice playing module, LCD MODULE.
Single-chip microcontroller of the invention uses STC89C52 single chip, and the model of GPS module uses VK-16U6, liquid crystal display mode
Block uses LCD12864 liquid crystal display, and voice playing module uses MX6200 speech player.
