The public transport electronic stop plate
The utility model relates to traffic signal devices, more particularly, relates to a kind of electronic stop plate that is applicable to the mass transportation facilities system.
The station board of existing motorbus/electric car, generally be with a certain bus the name of station of process simply enumerate out in order, title from each website of origin-to-destination can only be prompted to the public, information such as can not provide next distance that is about to the present point leaving from station of car that arrives, when can arrive.Along with making constant progress of science and technology, Global Positioning System (GPS) (GPS) has been widely used on the vehicle, can determine the vehicle position at any time; On the other hand, the incoming call display function of mobile communications network, the exhaling or broadcast capability etc. of paging system is for the above-mentioned shortcoming that overcomes existing station board provides feasibility.
The purpose of this utility model provides a kind of public transport electronic stop plate, can overcome the above-mentioned shortcoming of existing station board, realizes the advance notice function of arriving at a station of public transit vehicle, information such as provide next distance that is about to the present point leaving from station of car that arrives, when can arrive.
The objective of the invention is to realize by following scheme, construct a kind of public transport electronic stop plate, it is characterized in that, described station board is provided with the vehicle distant warning device that arrives at a station, comprise receive vehicle arrive at a station the receiving element of signal, the decoding unit that is connected with described receiving element, realization control and treatment central control unit (MCU) and be used to the pre-notice hint unit of pointing out vehicle to arrive at a station situation.
In the public transport electronic stop plate that provides according to the utility model, described receiving element adopts the radio paging receiver of the running status that can receive the vehicle that is sent by vehicle management center.
In the public transport electronic stop plate that provides according to the utility model, described Tip element be arranged at described station board surface with each site name corresponding LED pilot lamp.
In the public transport electronic stop plate that provides according to the utility model, described Tip element be arranged at described station board surface be used to be shown to stop spacing from or the display device of arrival time.
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the theory diagram of the utility model electronic stop plate;
Fig. 2 is the circuit theory diagrams of the utility model electronic stop plate;
Fig. 3 is the synoptic diagram that the utility model electronic stop plate is applied to public transit system.
As shown in Figure 1, the arrive at a station theory diagram of distant warning device of the vehicle that is provided with on the public transport electronic stop plate of the present utility model, comprise receive vehicle arrive at a station the receiving element 1 of signal, the decoding unit 2 that is connected with described receiving element, realization control and treatment central control unit 3 (MCU) and be used to the pre-notice hint unit 4 of pointing out vehicle to arrive at a station situation.
Wherein, described receiving element 1 adopts radio paging receiver, can receive the running status of the vehicle that is sent by traffic hub.Described Tip element 2 can be arranged at described station board surface with each site name corresponding LED pilot lamp, can show vehicle along the line and each website apart from situation; Described Tip element 2 can also be arranged at described station board surface be used to be shown to stop spacing from or the display device of arrival time, be used to show the distance of the vehicle of the fastest arrival our station and our station or be about to arrive time of our station.
Be illustrated in figure 2 as the circuit diagram of electronic stop plate, that a part of circuit that the LED that do not draw in this circuit shows, as can be seen from the figure, send over the electronic stop plate paging information after acceptance of RF receiving unit and demodulation process by vehicle management center, form fsk modulated signal and send decoding chip (D204 CIC92800 FLEX) to decode, decoded information is read in by the P1 mouth of central control unit (MCU) and is sent LED to show after treatment.
Be illustrated in figure 3 as electronic stop plate and be applied to synoptic diagram in the public transit system, wherein public transit vehicle 11 is provided with the GPS/GSM terminal, the receiver and the communication terminal that are about to Global Positioning System (GPS) (GPS) are one also, determine the vehicle position thereby can receive the signal sent by satellite 10, also can with 16 communications of mobile communication office.
Vehicle 11 is when master station dispatches a car, and login once tells this car from first station, and vehicle management center 12 deposits this information in data list and is equipped with shelves.Login mode is to adopt communication terminal on the vehicle 11 dial automatically (center is provided with a fixed number), pass to vehicle management center 12 by mobile communication office 16, telecommunication bureau 15, vehicle management center 12 can distinguish it is which car by caller identification, converses without off-hook.
Have a plurality of locating information on the GPS/GSM terminal of vehicle 11, concrete quantity can be consistent with the station number of this bus, be permanent haulage line owing to what travel, so locating information determined.Determining of this locating information is according to following principle: apart from the locating information at next station board N rice, wherein N can be made as 5~5000m.When a car reaches apart from next station board N rice, because of terminal constantly receives satnav information through the GPS receiver, when locating information was consistent with N, terminal was just from 12 dialing of trend vehicle management center, and center 12 just can distinguish how many distances this vehicle 11 also has apart from station board 14 at once.At this moment vehicle management center 12 is dealt into this information by paging network 13 electronic stop plate 14 of this website, corresponding LED is just bright, can indicate LED and illustrate that what minutes this vehicle 11 also has arrive at a station or also have how many distances from our station in addition when bright on electronic stop plate 14.
