Description

  The present invention constantly monitors the traffic conditions of automobiles (including special vehicles and motorcycles) in intersections, such as speeding violations, signal ignorance, and traffic volume. Car traffic within the intersection that can be acquired and can control traffic lights to ensure the safety of the vulnerable walking person when a vulnerable person such as a disabled person, an elderly person, a wheelchair, or an infant crosses the pedestrian crossing at the intersection The present invention relates to a traffic light control system for monitoring and weak walking.

  Conventionally, as a device for monitoring the traffic situation of an automobile, there are a vehicle photographing device using a CCD camera, a vehicle detection device using an ultrasonic sensor, and the like. The equipment is often installed on straight sections of arterial roads to monitor traffic volume, constantly monitoring traffic conditions such as speed violations and signal ignorance in intersections, and analyzing the cause of an accident when a traffic accident occurs. It was never used. It also detects whether pedestrians are able to cross within a specified time on a pedestrian crossing, or are vulnerable persons such as disabled people, elderly people, wheelchairs, and infants who are unable to cross over. There was no system to control the traffic lights to ensure that.

  Further, in recent years, RFID (Radio Frequency Identification) tag systems have been widely used, and are beginning to be applied in various fields other than the alternative use of barcode systems in the original physical distribution. The RFID tag system transmits a command signal by an electromagnetic wave from a reader (if it has a writing function, it is called a reader / writer), and the RFID tag receives the electromagnetic wave and modulates / demodulates using an induced electromotive force generated in a tuning circuit as a power source. By performing the operation and returning the unique ID information and the like stored in the RFID tag as a response signal, communication can be performed without contact and without battery.

  As an example of a system for controlling a traffic signal at an intersection using the RFID tag, a "signal control device" disclosed in Japanese Patent Laid-Open No. 05-205193 is provided with a responder (RFID tag) in which destination information is written in an emergency vehicle. A system is described in which a traffic light is controlled according to a destination of the emergency vehicle when destination information is read from a responder of the emergency vehicle by an interrogator (reader) attached to the traffic light. . In addition, in the “crossing moving body detection system” disclosed in Japanese Patent Application Laid-Open No. 2005-50161, an antenna is laid in a white belt line constituting a pedestrian crossing, connected to a stationary reader, and attached to a crossing moving body such as a pedestrian. A system is described in which a RFID tag is detected and the lighting timing and lighting time of a traffic light are controlled based on the detected information.

JP 05-205193 JP-A-2005-50161

  However, in Japanese Patent Laid-Open No. 05-205193, an emergency tag such as an ambulance or a patrol car is intended to smoothly pass through a road, and therefore an RFID tag is attached only to the emergency vehicle. Therefore, it is not attached to a general automobile, and the traffic of the automobile in the intersection cannot be monitored. Moreover, in the above Japanese Patent Laid-Open No. 2005-50161, an antenna is laid in the band of the pedestrian crossing and connected to a stationary reader. Depending on the type and configuration of the antenna, a plurality of stationary readers may be required, or antenna switching means may be provided. There was a problem that the installation cost would be large, such as being necessary. In addition, the antenna element may be formed of conductive paint, but using a conductive paint with a slight resistance will cause a decrease in resonance characteristics and communication due to a shift in resonance frequency due to expansion / contraction of the road surface and unevenness. There was also a problem that there was concern about the instability of.

  The present invention has been made to solve the above-described problems. By constantly monitoring and recording the traffic situation of every automobile in the intersection, an automobile-car collision accident and an automobile-walking are performed. In the event of a traffic accident such as a collision of a weak person, it is possible to analyze the cause of the accident and obtain information on traffic jams. It is an object of the present invention to provide a traffic light monitoring system for traffic monitoring of a car in an intersection and a traffic light control system for vulnerable walkers, which can control traffic signals (for vehicles and pedestrians) inexpensively and reliably.

  In order to solve the above problems, the traffic signal monitoring system for traffic monitoring and walking weak people in the intersection of the present invention is a vehicle inspection sticker equipped with an RFID tag that records vehicle number information in the vehicle. A reader is attached to the vehicle traffic signal and the pedestrian traffic light, and is attached to the front and the vicinity of the vehicle traffic signal and the pedestrian traffic signal. The car number information of a certain automobile is always read at a constant cycle. In addition, in the case of weak walkers, a pedestrian is provided with a certificate for mounting an RFID tag that records the certification information, and reading the certification information from the RFID tag of the certification and reading the car number information of the automobile. It is installed in a traffic signal, and the certification information of weak walkers in front and in the vicinity of the traffic signal for pedestrians is constantly read at a constant period.

  To the traffic signal control device installed in the vicinity of the intersection, the vehicle number information of the automobile read by the reader installed on the vehicle traffic signal and the pedestrian traffic signal and the certification information of the vulnerable person read by the reader installed on the pedestrian traffic signal. The vehicle speed information and the direction and the intersection approach timing of the vehicle traveling within the intersection are obtained from the vehicle number information, and the walking speed and direction of the vulnerable person crossing the pedestrian crossing at the intersection and the pedestrian walk from the authorized information. Obtain the timing, relay the information to the traffic monitoring center through the network, manage the information with the management server in the traffic monitoring center, analyze the cause of the accident when the traffic accident occurs, acquire the traffic jam information, and walk Control the lighting timing and lighting time of traffic lights to ensure the safety of the vulnerable.

  The car number information of the car includes the jurisdiction area, car type, code, and car number of the car, but may further include the model, owner name, vehicle inspection expiration date, and the like. In addition, although there are types and degrees of obstacles, certification numbers, names, addresses, etc., in the certification information for weak walkers, there is no particular limitation on which information content is included. In addition, it is preferable to use an encrypted message format for communication between the reader and each RFID tag when reading the vehicle number information or the authorization information.

  If the traffic monitoring system for traffic in the intersection of the present invention and the traffic light control system for vulnerable walkers are operated at intersections such as roads with heavy traffic and roads with many pedestrians, all the vehicles traveling within the intersection will travel. The situation can be constantly monitored with an inexpensive RFID tag mounted on a car inspection sticker and a reader installed on a traffic light for vehicles and a traffic light for pedestrians, and all vulnerable walkers cross the pedestrian crossing at the intersection. The situation can be detected constantly and stably with an inexpensive RFID tag mounted on a certificate and a reader installed in a pedestrian traffic light. Therefore, analysis of the cause of a traffic accident such as a collision accident between a car and a car or a collision accident between a car and a weak walking person, acquisition of traffic jam information, and when a weak walking person crosses the pedestrian crossing at the intersection, It is possible to achieve a tremendous effect that the control of the traffic light that secures safety first can be performed inexpensively and reliably.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an installation position and a monitoring range of a leader for automobile monitoring in a traffic control system for a traffic weakness and a traffic light control system for weak people in an intersection of the present invention, and FIG. 2 is affixed to the automobile in FIG. It is the figure which showed the reading condition of the RFID tag of the vehicle inspection sticker which was done. As shown in the figure, in the automobile 8, a vehicle inspection sticker equipped with an RFID tag 9 in which vehicle number information is recorded is attached to a predetermined position of the vehicle 8, and the vehicle number is determined from the RFID tag 9 of the vehicle inspection sticker. A reader 5 for reading the information and monitoring the automobile 8 is installed in the traffic signal 2 for the vehicle, and the vehicle number information of the automobile 8 in front and in the vicinity of the traffic signal 2 for the vehicle is constantly read at a constant period.

  Further, as shown in FIG. 1, the monitoring range 6 of the automobile monitoring leader 5 is assumed to be in front of the vehicle traffic signal 2 on which the leader 5 is installed and to the vicinity of the approximate center in the intersection 1. Therefore, when the automobile monitoring reader 5 is installed at the vehicle traffic lights 2 at the four intersections 1, the vehicle number information of the automobile 8 in the intersection 1 is read by at least one automobile monitoring reader 5. It will be.

  Next, FIG. 3 is a diagram showing an installation position and a detection range of a leader for detecting a weak walking person in a traffic light monitoring system for traffic monitoring and a weak walking person in an intersection of the present invention, and FIG. It is the figure which showed the reading condition of the RFID tag of the certificate affixed on the white cane of the weak walking person in FIG. As shown in the figure, the weak walking person 10 is attached with a certificate having an RFID tag 12 on which the certification information is recorded, and the certification information is read from the RFID tag 12 of the certification to detect the weak walking person 10. The pedestrian traffic light 4 is installed in the pedestrian traffic light 4, and the certification information of the weak walkers 10 in front and in the vicinity of the pedestrian traffic light 4 is always read at a constant period.

  As shown in FIG. 3, the detection range 7 of the reader 5 for detecting weak walkers is set to the front of the pedestrian traffic light 4 on which the reader 5 is installed and to the vicinity of the approximate center of the pedestrian crossing 3. Accordingly, when the pedestrian traffic lights 4 at both ends of each pedestrian crossing 3 are installed with the pedestrian weakness detection leader 5, the certification information of the pedestrian weak 10 at each pedestrian crossing 3 is at least one for detecting weak pedestrians. It is read by the reader 5.

  The reader 5 for detecting weak walkers also functions as a vehicle monitor, and the vehicle number information of the car 8 traveling on the pedestrian crossing 3 is read by at least two readers 5 for detecting weak walkers. . The monitoring range for vehicle monitoring is equivalent to the detection range 7 for detecting weak walkers.

  FIG. 7 is a structural example diagram of a vehicle inspection sticker used in the traffic control system for the traffic monitoring and walking weak person in the intersection of the present invention. The antenna 22 is arranged around the vehicle inspection expiration date marking part in the vehicle inspection sticker 21. The RFID tag 9 is configured by connecting the RFID chip 23 to the end of the antenna 22. In addition, the certification (not shown) attached to the person of the weak walking person 10 is also formed as a sticker like the vehicle inspection sticker 21 and mounted with the RFID tag 12 or mounted with the RFID tag 12 on an ID card or the like. Is preferred.

  8 is a block diagram showing an example of the RFID tag mounted on the vehicle inspection sticker shown in FIG. 7. The RFID tag 9 includes an antenna 22 and an RFID chip 23. The antenna 22 is connected to a tuning circuit 24 composed of a tuning capacitor (not shown) in the RFID chip 23 or partly outside the RFID chip 23 in order to perform radio communication with the reader 5 by electromagnetic waves. The resonant circuit is configured by being tuned to a carrier frequency used in a traffic light control system for traffic weakness and a traffic light control system for walking weak persons, for example, 953 MHz or 2.45 GHz. The antenna 22 is generally a loop antenna, and it is preferable to use a high-efficiency antenna material capable of obtaining a large mutual inductance for the lead wire of the loop antenna.

  In the subsequent stage of the tuning circuit 24, the voltage waveform of the induced electromotive force generated when the electromagnetic wave output from the antenna (not shown) of the reader 5 passes through the antenna 22 of the RFID tag 9 is detected, or the induction A rectifier circuit 25 is connected to extract a DC voltage by rectifying the electromotive force by half wave or full wave. A diode (not shown) used in the rectifier circuit 25 is preferably a diode having a low forward voltage drop, such as a Schottky barrier diode.

The charging capacitor 29 is generally a ceramic capacitor, and an electric double layer capacitor is suitable when electric power is required, but is not particularly limited.

  Next, after the modulation / demodulation circuit 27, control of the modulation / demodulation circuit 27 and unique ID information and vehicle number information of the RFID chip 23 with respect to FRAM (Ferroelectric RAM: registered trademark of Ramtron, USA) 31 which is a nonvolatile memory are provided. Alternatively, a logic circuit 30 for performing writing or reading control of data such as certification information is connected.

  The FRAM 31 is a ferroelectric nonvolatile memory, and data such as unique ID information and vehicle number information or certification information of the RFID chip 23 is not lost even when the circuit power is turned off. In addition, since the data write voltage does not need to be boosted to a high voltage unlike an EEPROM or a flash memory, the booster circuit is simplified. Further, the writing or reading speed is equivalent to that of DRAM, and is characterized by being much faster than EEPROM and flash memory. Thus, although FRAM31 is suitable as a non-volatile memory, other memories may be used.

  The block configuration of the RFID tag 12 mounted on the certificate that the weak walking person 10 attaches to the person's side is the same.
