Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
As shown in fig. 1 and 2, the bus rapid transit priority passing control system provided by the embodiment of the present invention includes: RFID label, RFID identification device, on-vehicle OBU, RSU and semaphore.
The RFID (Radio Frequency Identification) tag is installed at the front end of the bus rapid transit, and specifically, the RFID tag is installed on the front windshield of the bus rapid transit; and the bus rapid transit is provided with a vehicle-mounted OBU. The RFID tag has the characteristics of rapidness, accuracy, non-contact identification, stable and reliable communication and the like. The communication distance of the RFID tags is adjustable, and the RSU stores the running route information of the buses corresponding to different RFID tags.
The RFID identification device is in data connection with the RSU, and specifically, information interaction is performed between the RFID identification device and the RSU through an RS485 serial port line or an RJ45 network line. The RFID identification device is arranged on a road marker post in front of the crossroad, and a buffer distance is reserved between the road marker post and the crossroad; it is ensured that no obvious obstruction interferes with the reading of the card between the RFID tag and the RFID identification device, and the RFID identification device can identify the RFID tag right in front of the vehicle. Specifically, the RFID identification device may be an RFID reader, and the communication distance of the RFID identification device is about 50 meters. The speed of the vehicle passing through the intersection is about 30KM/H (8m/s), so that the reserved buffer distance is 50-150, preferably 100 meters, and the signal machine can know the information of the vehicle passing in advance.
The communication between the RFID identification device and the RSU adopts a Zigbee mode or an RFID mode, and the two schemes are that when a vehicle passes through a crossroad, a signal machine is informed in a wireless mode to request preferential passage. Only the way of wireless communication is different: a short-distance wireless communication is realized through Zigbee; a short-range wireless communication is realized by RFID.
The RSU (Road Side Unit) is in data connection with a signal machine; the RSU is internally provided with a memory, and the memory of the RSU stores the bus rapid transit information corresponding to different RFID tags; wherein the vehicle information includes: the vehicle number, the vehicle running route information and the intersection information passed by the vehicle.
When the rapid transit with the RFID tag passes through the road post, the RFID identification device on the road post identifies the RFID tag installed on the rapid transit and sends vehicle information corresponding to the RFID tag to the RSU; meanwhile, the On Board Unit (OBU) reports a priority pass request to the RSU through a special communication channel; the priority passing request carries the current position, the current traveling direction, the current running speed and the predicted time of arriving at the crossroad of the bus rapid transit.
The RSU acquires the ID information corresponding to the RFID tag and acquires the vehicle information of the bus rapid transit from a database; the RSU judges whether to accept the prior passing request of the vehicle-mounted OBU or not according to the vehicle information and the signal prior analysis rule; and when the RSU allows the bus rapid transit to carry out signal priority, the priority passing message of the applied phase is sent to the signal machine through the switching value.
After the signaler obtains the priority traffic message, the signaler carries out traffic signal lamp scheduling according to the remaining time of the current traffic light and the predicted remaining time of the bus rapid transit to reach the crossroad, and returns a scheduling result to the vehicle-mounted OBU through the RSU; the traffic signal lamp scheduling realizes early red light break or green light extension by regulating and controlling the remaining seconds of the current state of the traffic signal lamp, and ensures that the green light of the traffic signal lamp is on when the bus rapid transit passes through the crossroad, and the bus rapid transit directly passes through. The signal machine controls the residual on-off time of the traffic lights through a red light early-off or green light prolonging strategy, and ensures that the green lights can pass through without stopping when the bus arrives at the intersection to a certain extent.
On the basis of the above scheme, the RSU specifically includes: the system comprises a wireless communication module, a resolver, an RSU processing module and a log module; the vehicle-mounted OBU sends the priority passing request to the resolver through the wireless communication module; the resolver resolves a priority passing request of the vehicle-mounted OBU and sends the priority passing request to the RSU processing module, the RSU processing module judges whether the priority passing request meets a signal priority analysis rule, if the priority passing request meets the signal priority analysis rule, the bus rapid transit is allowed to pass preferentially, and traffic signal lamp scheduling is carried out; if the signal priority analysis rule is not met, the bus rapid transit is not allowed to pass through preferentially; the RSU processing module generates a priority passing message and a scheduling result, sends the priority passing message to a signal machine, and feeds the scheduling result back to the vehicle-mounted OBU; and the log module is used for forming a scheduling log.
In addition, the RSU can be placed on the signal side of the intersection, said RSU comprising four passive trunk contact signals, each passive trunk contact representing a phase request; as shown in fig. 3, the RSU is configured with a main control board, a relay board, an RJ45 network cable interface, a 2A/B relay, and a 5V power interface. In this embodiment, the wireless communication module is a Zigbee module or an RFID module. The RSU of this embodiment can read the configuration file, obtain the steering direction of the vehicle, and then send a traffic request to the traffic signal at the corresponding phase. The request is for the passive dry contact to close. After the request is sent, the time lasts for about 1 second, the dry contact is disconnected, and the request is released. The RSU processes each request for an interval of 10 seconds. After receiving each request, the RSU processes the next request only after 10 seconds, thereby preventing the problem of repeated card reading.
In the above scheme, the signal priority analysis rule has the following characteristics:
when the release direction is green and the remaining green time is enough for the bus rapid transit to normally pass through the current crossroad, the signal machine does not control;
when the release direction is green light and the residual green light time is not enough for the fast bus to pass through the intersection, the signaler performs green light extension control, wherein the green light extension time is the time required by the fast bus to reach a stop line at the current speed-the residual green light time;
when the release direction is the red light this moment, the semaphore will do the early control of red light, compresses the green light time of other release directions promptly, and the maximum time that can compress is other release directions total green light time-total minimum green time.
In this embodiment, since the RFID tag can be read within the identification range of the RFID identification device, the RSU can be configured with a certain limit that the same card ID is considered as a valid card ID only when it is received again after more than 10 seconds. When the RSU sends a phase request, the red light can be seen on the corresponding phase port of the RSU, and then for about 1 second, the dry contact is opened again, releasing the request.
Further, a vehicle-mounted DVR (Digital Video Recorder) is arranged on the bus rapid transit, and the vehicle-mounted DVR is in data connection with a control center; the vehicle-mounted DVR collects video data in the vehicle and uploads the video data to the control center through a 3G/4G network. According to the monitoring system for the bus rapid transit configuration, workers in a bus can perform emergency alarm on a control center by triggering an emergency alarm button, and can transmit bus rapid transit position information to the control center through a GPS positioning device.
Furthermore, a shooting device is arranged on the bus rapid transit, and the shooting device shoots image data in the bus rapid transit and uploads the image data to a control center; the control center identifies the number of people in the image data, and when the number of people in the image data exceeds a threshold value, an alarm prompt is given to prompt that the full-load operation of the bus rapid transit is performed, and operation scheduling is increased in time to relieve the bus pressure.
Further, the vehicle-mounted OBU is in data connection with the control center; the vehicle-mounted OBU is also in data connection with a monitoring system configured by the bus rapid transit; alarm signals in the vehicle are monitored by the vehicle-mounted OBU in real time, and when the alarm signals are generated in the monitoring system, the vehicle-mounted OBU uploads alarm information to the control center. The vehicle-mounted OBU monitors alarm signals in the vehicle in real time, and when the alarm signals are generated, such as an emergency alarm button alarm, the equipment can upload alarm information to a control center in time according to an alarm configuration strategy.
Furthermore, the road sign pole is provided with a first optical sensor, a second optical sensor is arranged below the crossroad signal lamp, and the first optical sensor and the second optical sensor are respectively in data connection with a signal machine; the first optical sensor monitors the number of vehicles to pass through the road sign post and uploads the number of the vehicles to the signal machine; the second light sensor monitors the number of vehicles that have passed through the intersection and uploads to the annunciator.
The traffic signal machine judges the number of vehicles to be passed at the crossroad according to the information uploaded by the first optical sensor and the second optical sensor, when the number of the vehicles to be passed exceeds a threshold value, the traffic signal machine judges that the road is congested, the traffic signal machine controls the traffic signal lamp, and the road congestion is relieved by adopting a red light early-breaking or green light prolonging mode. The control of the situation can be combined with the road condition of the vertical lane, and the effect of relieving traffic jam is better under the condition that the vertical lane is not jammed.
Further, a display screen is configured on the bus rapid transit; the display screen is in data connection with the signal machine, and the number of the vehicles to be passed, the current speed, the predicted time of arriving at the crossroad and the current state of the traffic signal lamp are displayed on the display screen.
