Traffic altogether.But with being continuously increased for urban public traffic vehicles and public transport order of classes or grades at school, safety problem when passenger takes bus also is got over
Receive publicity to get over.At present, the bus platform of China's buses is substantially provided on road side, and bus platform outside is exactly high
The automobile of speed traveling, this takes bus for passenger and has buried potential safety hazard.At present, also there is urban in some bus platforms
It is mounted with shield door and passenger and extraneous vehicle is completely cut off with this, or is specially provided with safe pilot, but both approaches are needed
Put into substantial contribution.Therefore, the bus platform safety reminding device of a kind of efficient, low price and convenient later maintenance is just embodied
Its advantage.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, this utility model to provide a kind of bus platform based on piezoelectric
Safety reminding device, piezoelectric transducer is imbedded in bus platform on the road surface of road side, by being wirelessly transferred pressure
Signal is sent to speech prompting device, when buses do not arrive at a station or do not come to a complete stop and have passenger to enter bus platform outside near road
During the hazardous area of side, speech prompting device will automatically send alarm, and reminding passengers are waited in place of safety.
This utility model solves the technical scheme that its technical problem adopted：The bus platform safety reminding device includes
Piezoelectric transducer, platform radio transmitters, wireless receiver (), controller, onboard wireless transmitter, wireless receiver
And speech prompting device (two).
Described piezoelectric transducer adopts PVDF piezoelectric film sensors, is embedded in roadbed of the bus platform near road side
In, the outfan of PVDF piezoelectric film sensors is connected with the input of platform radio transmitters.
Described platform radio transmitters and onboard wireless transmitter adopt bluetooth transmission technology, described wireless receiver
And wireless receiver (two) is using Bluetooth receptions technology (one)；The outfan of platform radio transmitters and wireless receiver ()
Input is connected, and onboard wireless transmitter is arranged on buses, the input phase of its outfan and wireless receiver (two)
Connection；The outfan of wireless receiver () and wireless receiver (two) is input into respectively with the first input end and second of controller
End is connected.When there is passenger to enter bus platform near road side hazardous area when buses do not arrive at a station or do not come to a complete stop, pressure
Force transducer receives the gravity from people, transmits a signal to platform radio transmitters, and platform radio transmitters are again by signal
Wireless receiver (one) is transferred to by Bluetooth technology, wireless receiver () transmits a signal to the first input of controller
End；When bus arrival and after come to a complete stop, driver opens the onboard wireless transmitter being installed on buses, onboard wireless transmitter
Send the car signal that arrives at a station to wireless receiver (two), wireless receiver (two) transmits a signal to the second input of controller
End.When buses do not arrive at a station or do not come to a complete stop, driver is not turned on the onboard wireless transmitter being installed on buses, then controller
Second input no signal is input into.
Described controller adopts single-chip microcomputer, the outfan of controller to be connected with the input of speech prompting device.
Described speech prompting device adopts acoustical quality good and low-cost ISD1760 speech chips.
The bus platform safety reminding device that this utility model is provided, has the advantages that：
1st, using being embedded in PVDF piezoelectric film sensor of the bus platform in the roadbed of road side, when buses also not
Get to the station or when car does not come to a complete stop, when passenger enters into bus platform near road side hazardous area, speech prompting device
Alarm will be automatically sent, reminding passengers are waited in place of safety.
2nd, the PVDF piezoelectric film sensors that this utility model is adopted adopt the mounting means of " burying ", will not be to traffic flow
Have any impact, and the characteristic of piezoelectric itself determines that it is a kind of new self-powered sensor, environmental protection.

Fig. 1 is a kind of each module diagram of bus platform safety reminding device based on piezoelectric of this utility model.
Fig. 2 is a kind of use schematic diagram of the bus platform safety reminding device based on piezoelectric of this utility model.
Description of reference numerals：1 piezoelectric transducer, 2 platform radio transmitters, 3 wireless receivers (), 4 controllers, 5 cars
Carry radio transmitters, 6 wireless receivers (two), 7 speech prompting devices.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail.
As shown in Figure 1-2, a kind of bus platform safety reminding device based on piezoelectric of this utility model, including piezoelectricity
Sensor 1, platform radio transmitters 2, wireless receiver () 3, controller 4, onboard wireless transmitter 5, wireless receiver
(2) 6 and speech prompting device 7.Piezoelectric transducer 1 is embedded in bus platform in the roadbed of road side, piezoelectric transducer 1
Outfan be connected with the input of platform radio transmitters 2, the outfan of platform radio transmitters 2 and wireless receiver ()
3 input connection, the outfan of wireless receiver () 3 is connected with the first input end of controller 4；Onboard wireless transmitter
5 outfan is connected with the input of wireless receiver (two) 6, the outfan of wireless receiver (two) 6 and the second of controller 4
Input connects；The outfan of controller 4 is connected with the input of speech prompting device 7.
When have passenger when buses do not arrive at a station or do not come to a complete stop into bus platform near the hazardous area of road side, pressure
