Background technology
Along with high development of social economy, urban traffic conditions goes from bad to worse, public transit vehicle or some particular vehicle, by the traffic lights crossing time, should set the right-of-way of higher priority as the vehicle of attending a meeting of bus, ambulance, fire truck, momentous conference etc., to improve its crossing traffic efficiency.
Aspect the traffic efficiency of raising public transit vehicle crossing, some measures have been taked in some city, specialize in the bus zone that public transit vehicle uses as offering for bus, improved the operational efficiency of bus to a certain extent, but at traffic intersection, bus still need must be indicated current in accordance with traffic lights, can occur waiting for that traffic lights replace situation about still can't pass through for several times, has a strong impact on the operational efficiency of bus.
CN101458873 discloses a kind of real-time control method of the public transport priority signal based on RFID, it installs the RFID electronic chip on bus, the 2nd a RFID reader and a RFID reader are installed at the parting of the ways, and with above-mentioned reader and signal conditioning package, the traffic lights management devices connects, all define the address for each highway section, and this address write corresponding reader, when vehicle during through a RFID reader, read electronic code and itself and address are sent to signal conditioning package, this device is also added up the information deletion of correspondence with all memory informations, analyze, provide row information to traffic lights management devices and switch traffic lights, this technical scheme can improve the priority level of bus, improves the pass through efficient of bus at the crossing.
But the defective of such scheme is that each crossing all needs to install two RFID readers could detect collection bus information, has increased the transformation difficulty to existing crossing facility.Nonetheless yet can't realize accurate location, the bus accurate location information can't be offered signal conditioning package to realize to the current optimization in bus crossing to bus.
The utility model content
Technical problem to be solved in the utility model is that prior art can't accurately learn the accurate position of public transit vehicle near the crossing time, cause signal conditioning package can't more reasonably control traffic lights, and then provide a kind of public traffic in priority shortcut mouth location to gather and the priority signal connecting system, can be on the basis that multiple transport information is analyzed to the crossing, belisha beacon is rationally controlled, improved the traffic efficiency of public transit vehicle at the crossing.
For this reason, the technical scheme that the utility model adopted is:
Gather and the priority signal connecting system a kind of public traffic in priority shortcut mouth location, comprises
Be installed on RFID electronic tag on the public transit vehicle, be installed on the upper end control platform that receives RFID electronic tag RFID signals reader, be arranged at the traffic signal control at crossing and be arranged on traffic administration command centre of being used to of trackside check point; Also comprise signal processing unit, described signal processing unit comprises:
RFID signal receiving module: be used to receive the RFID electronic tag signal that described RFID reader sends;
RSSI technology measuring and calculating module: be used for determining the residing position of public transit vehicle according to the RFID electronic tag signal that receives;
Data resolution module: be used for RSSI technology measuring and calculating module is recorded data with parameter preset is compared, and comparison result be sent to traffic signal control and/or platform is controlled in the upper end;
Described traffic signal control is according to the current belisha beacon show state of instruction control of the instruction or the data resolution module transmission of upper end control platform.
Described data resolution module comprises that also the compare of analysis adjacent intersection magnitude of traffic flow, current belisha beacon situation judge current crossing letting pass or forbidden.
Transmit by wireless signal between described RFID reader and the described RFID signal receiving module.
Described RFID reader be installed on along the tested vehicle working direction apart from the crossing about 100 meters with interior place.
Described RFID reader is installed on shortcut mouth scope interior the monitoring bar or sign board.
The beneficial effects of the utility model are:
1, by RSSI technology measuring and calculating module in the signal processing unit, can be according to the RFID electronic tag signal that receives, determine the residing position of public transit vehicle, RSSI technology measuring and calculating module is recorded data to data resolution module and parameter preset is compared, and comparison result is sent to traffic signal control and/or upper end control platform, traffic signal control is according to the current belisha beacon show state of instruction control of the instruction or the data resolution module transmission of upper end control platform, the more accurate setting public transit vehicle crossing scheme of passing through improves the crossing traffic efficiency of public transit vehicle.
2, by the RFID reader being installed on shortcut mouth monitoring bar or the sign board, effectively utilize existing means of transportation, saved improvement expenses.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a structural representation block diagram of the present utility model.
Embodiment
In conjunction with shown in Figure 1, gather and the priority signal connecting system a kind of public traffic in priority shortcut mouth location, comprises the RFID electronic tag that is installed on the public transit vehicle, is installed on the upper end control platform that receives RFID electronic tag RFID signals reader, signal processing unit, be arranged at the traffic signal control at crossing and be arranged on traffic administration command centre of being used to of crossing monitoring bar.
Described signal processing unit comprises RFID signal receiving module, RSSI technology measuring and calculating module and data resolution module.The RFID signal receiving module receives the RFID electronic tag signal that described RFID reader sends by wireless signal, RSSI technology measuring and calculating module is determined the residing position of public transit vehicle according to the RFID electronic tag signal that receives, RSSI technology measuring and calculating module is recorded data to data resolution module and parameter preset is compared, go back information such as the compare of analysis adjacent intersection magnitude of traffic flow, current belisha beacon situation simultaneously, and comparison result is sent to traffic signal control and upper end control platform; Described traffic signal control is according to the current belisha beacon show state of instruction control of the instruction or the data resolution module transmission of upper end control platform.
