Embodiment:
Below provide a kind of possible embodiment, be not limited to this mode in the practice:
Use single-chip microcomputer to be example as control system with traffic light control system (0), native system also adopts single-chip microcomputer as control system, forms shown in the synoptic diagram as Fig. 1 system to link to each other with traffic light control system (0) by serial ports.
The selection of interface (11) implementation is a principle with the data that can gather traffic light control system (0) reliably and to original traffic light control system (0) influence minimum.
System be installed in the control box or near, FM transmission antenna correspondingly is set, lightning protection device.
After starting working, system can broadcast locating information and the traffic lights signal speech information as Fig. 4 traffic lights signal and voice correspondence principle synoptic diagram shown in of this crossing shown in Fig. 3 traffic intersection locating information synoptic diagram by frequency-modulated wave.
The layout of traffic lights signal speech information then be data process subsystem (1) shown in Fig. 2 data process subsystem (1) structured flowchart by the data that collect are handled at main control unit (12), according to the logic shown in Fig. 5 voice messaging layout principle flow chart, use speech chip technology or TTS technology that corresponding information of voice prompt is converted into audio signal output by voice control module (13).
The sound signal of data process subsystem (1) output is as the input signal of frequency-modulated wave emission subsystem 3, and the frequency-modulated wave broadcast mode that sound signal is converted into certain frequency is launched.
Traffic participant (comprising blind person, traveller and driver) receives the voice suggestion that playback subsystem (being FM receiver) (3) can be listened to traffic intersection locating information, traffic lights information by frequency-modulated wave.
The situation information receiver is with the voice sample of receiving as shown in drawings:
" people road direction is current for Beijing road and intersection, people road, map retrieval information: 6F, and Beijing road direction stops, and current transit time remains XX second, and people road direction is current, and Beijing road direction stops, and current transit time remains XX second ... "
Being repeated to signal lamp switches.
" people's road direction Beijing road direction vehicle turns left; no through traffic for the pedestrian for Beijing road and intersection, people road, map retrieval information: 6F, and current transit time remains XX second, and people's road direction Beijing road direction vehicle turns left; no through traffic for the pedestrian, and current transit time remains XX second ... "
Being repeated to signal lamp switches.
" Beijing road direction is current for Beijing road and intersection, people road, map retrieval information: 6F, and people road direction stops, and current transit time remains XX second, and Beijing road direction is current, and people road direction stops, and current transit time remains XX second ... "
Being repeated to signal lamp switches.
" road direction people road, Beijing direction vehicle turns left; no through traffic for the pedestrian for Beijing road and intersection, people road, map retrieval information: 6F, and current transit time remains XX second, and people's road direction Beijing road direction vehicle turns left; no through traffic for the pedestrian, and current transit time remains XX second ... "
Being repeated to signal lamp switches.
Voice suggestion as above can provide traffic intersection locating information and traffic lights information and instruct traffic participant (particularly blind person, driver) to pass through the crossing for traffic participant (particularly blind person, driver and traveller).
The composition of each unit is simple in the system of the present invention, can directly adopt the commercial goods as ingredient.
The power setting of frequency-modulated wave transmitter is advisable in guaranteeing the traffic intersection certain limit without interruption in the practical application, avoids overlapping with the frequency-modulated wave signal at next crossing.
