Abstract
The invention discloses a real-time control method for public traffic priority signal based on RFID, wherein a RFID electronic chip is mounted on a bus, a second RFID reader and a first RFID reader are mounted at crossroad, the first RFID reader and the second RFID reader are both connected with an information processor and a traffic light manager; each road is defined of addresses written into corresponding readers; when bus passes by the first RFID reader, electronic codes are read and transmitted with the addresses to the information processor, after receiving the electronic codes and addresses, the information processor judges and stores the bus information; when the bus passes by the second RFID reader, the reader reads electronic codes and transmits the information to the information processor, the information processor deletes corresponding information, processes statistic and analysis on all memory information, and sends release information to the traffic light manager to switch traffic light. The invention can further improve the operation efficiency of buses.
Description
Technical field
The present invention relates to the automatic identification technology field, specifically is a kind of real-time control method of the public transport priority signal based on RFID.
Background technology
As everyone knows, public transport not only provides convenience for masses' trip, and the advantage of its economy, environmental protection has great social benefit.But along with The development in society and economy, the going from bad to worse of urban transportation operation conditions, thus cause the overall operation efficiency of public transit system not high.In order to solve above-mentioned situation, more domestic cities the passage that public transit vehicle uses occurred specializing at traffic lights at present, this has improved the operational efficiency of public transport to a certain extent, but the operational efficiency of public transport is still lower, utility car still needs to observe the traffic light signal of intersection, and some busier highway section is because city vehicle is more, can occur waiting for that green light and red light have replaced several times, but still fail by the situation at this crossing, and this situation can have a strong impact on passenger's mood, change and take advantage of other vehicles or buy private car, cause city vehicle to increase again, thereby bring the vicious cycle of urban transportation.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defective of above prior art, and a kind of real-time control method based on the public transport priority signal of RFID of further raising public transit vehicle operational efficiency is provided.
Technical scheme of the present invention is, a kind of real-time control method of the public transport priority signal based on RFID is provided, and may further comprise the steps:
(1) in the city, on all public transit vehicle the RFID electronic chip is installed all, in the east of right-angled intersection, four highway section mouths in south, west, north all install the 2nd RFID reader, apart from the some distances of the 2nd RFID reader the one RFID reader are installed all in four highway sections; The one RFID reader, the 2nd RFID reader in four highway sections all are electrically connected with signal conditioning package; Signal conditioning package is electrically connected with the traffic lights management devices;
(2) all define a described RFID reader, signal conditioning package, all discernible address of traffic lights management devices for four highway sections, and this address is write a RFID reader and the 2nd RFID reader of four highway section correspondences respectively;
(3) when the public transit vehicle that the RFID electronic chip is installed during, read the electronic code of this public transit vehicle and this electronic code and this highway section corresponding address are transferred to signal conditioning package by a described RFID reader through the read range of a RFID reader;
(4) after signal conditioning package is received the electronic code and address that is transmitted by a RFID reader, be positioned at any bar highway section by reading the public transit vehicle of promptly judging this electronic code correspondence in electronic code and address, and these information of vehicles are stored in the signal conditioning package;
(5) when the public transit vehicle that the RFID electronic chip is installed during, read the electronic code of this public transit vehicle and this electronic code and this highway section corresponding address are transferred to signal conditioning package by described the 2nd RFID reader through the read range of the 2nd RFID reader;
(6) in the time of after signal conditioning package is received the electronic code of this vehicle that is transmitted by second reader and address, then will be stored in the signal conditioning package should electronic code and the information of vehicles deletion of address;
(7) signal conditioning package is analyzed according to the information that is stored in the signal conditioning package, count the quantity of bus on east, south, west, four highway sections, north, the summation of public transit vehicle on east, summation and south, the North Road section of public transit vehicle on the section of West Road is compared: if the summation of public transit vehicle is greater than the summation of public transit vehicle on southern, the North Road section on the east, West Road section, then judge the public transit vehicle clearance of east, West Road section, east, West Road section corresponding address information are sent to the traffic lights management devices; If the summation of public transit vehicle is less than the summation of public transit vehicle on south, the North Road section on east, the West Road section, judge that then the public transit vehicle on south, the North Road section is let pass, south, North Road section corresponding address information are sent to the traffic lights management devices; If the summation of public transit vehicle equals the summation of public transit vehicle on south, the North Road section on east, the West Road section, then select the clearance information of south, North Road section or east, West Road section to be sent to the traffic lights management devices randomly by signal conditioning package;
(8) the traffic lights management devices switches the traffic lights of this intersection according to the address information that receives.
After adopting above method, the present invention compared with prior art has the following advantages:
The present invention utilizes the RFID technology of prior art, in the city, on all public transit vehicle the RFID electronic chip is installed all, each highway section mouth in the intersection that is provided with the bus designated lane is all installed the 2nd RFID reader, apart from the some distances of the 2nd RFID reader the one RFID reader is installed all in each highway section; The one RFID reader, the 2nd RFID reader in each highway section all are electrically connected with signal conditioning package; Signal conditioning package is electrically connected with the traffic lights management devices; Signal conditioning package by above-mentioned RFID chip and RFID reader count on east, West Road section Shang Henan, the North Road section gross vehicle and, the highway section prior-release that vehicle is more, situation according to this each highway section, intersection is switched traffic lights, saved the time of bus wait traffic lights, thereby improved the operational efficiency of bus, and because the raising of bus running efficient, cause and take a taxi or the people of private car reduces, limited to a certain extent the increase of city vehicle, alleviated the pressure of urban transportation effectively.
