  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram schematically showing an entire parking lot security system employing a road-to-vehicle security system according to the present invention. This parking lot security system includes a parking lot management center 10 installed in a parking lot PK that serves as a roadside security system, a plurality of narrow area wireless communication roadside devices 20 (hereinafter referred to as DSRC roadside devices 20), a vehicle BD The vehicle-mounted security system 30 and the narrow-range wireless communication vehicle-mounted device 40 (hereinafter referred to as the DSRC vehicle-mounted device 40).

  The parking lot PK is provided with a plurality of monitoring cameras KC capable of photographing the inside of the parking lot. In the parking lot management center 10, a guard is stationed in a monitor room equipped with a monitor 11, and the guard can view the inside of the venue by viewing the captured image and the reproduced image of the monitoring camera KC projected on the monitor 11. It is configured to be monitored. The parking lot management center 10 is provided with a control device 12 and a communication device 13.

  The control device 12 (roadside control means) includes a microcomputer including a timer 12a as a main component, and is connected to the control units 21 in the plurality of DSRC roadside devices 20 via the LAN cable 51 so as to be able to communicate with each other. ing. The control device 12 exchanges communication data with the DSRC vehicle-mounted device 40 of the parked vehicle through the DSRC roadside device 20. Specifically, the control device 12 sends a sleep instruction signal based on the count of the timer 12a and a wake-up instruction signal based on a detection signal from the human body sensor 22 described later to the DSRC on-vehicle device 40 via the DSRC roadside device 20. On the other hand, an abnormal signal of the vehicle BD detected by the in-vehicle security system 30 and a signal indicating the remaining battery level are received from the DSRC in-vehicle device 40 via the DSRC roadside device 20, and a detection signal by the human body sensor 22 is received from the DSRC. Receive from the roadside machine 20.

  The communication device 13 is capable of communicating with a mobile communication terminal (for example, a mobile phone) of a vehicle parked in the parking lot PK, and when an abnormality of the vehicle is detected by the in-vehicle security system 30, the in-vehicle security system 30 is configured to receive a signal representing an abnormality of the vehicle BD.

  The DSRC roadside machine 20 is a wireless device installed in the parking lot PK, and is provided in the parking lot PK at a ratio of one machine to one to three parking spaces, for example. The control unit 21 in the DSRC roadside machine 20 includes a microcomputer as a main component, and is connected to the human body detection sensor 22, and when the human body is detected by the human body detection sensor 22, the detection signal, A signal representing a roadside machine number predetermined for each DSRC roadside machine 20 is transmitted to the control device 12.

  The human body detection sensor 22 is an infrared sensor used for sensor light, for example, and detects a vehicle BD entering / exiting a parking space as well as a person approaching the vehicle BD and outputs a detection signal. Thus, if the above infrared sensor is used as the human body sensor 22, the DSRC roadside machine 20 can be configured at low cost. In addition to or instead of the infrared sensor as the human body sensor 22, for example, a CCD camera or an ultrasonic sensor may be used to detect only a person approaching the vehicle with high accuracy.

  The in-vehicle security system 30 is turned on in response to a lock signal from the key lock 32 of the vehicle BD (security ON state). The vehicle abnormality information detection unit 31 in the in-vehicle security system 30 includes a microcomputer as a main component, and is connected to a vibration sensor 33, an inclination sensor 34, and a door opening / closing sensor 35. The vibration sensor 33 detects the vibration / impact of the vehicle BD in the parked state. The inclination sensor 34 detects the inclination of the vehicle BD in the parking state. The door opening / closing sensor 35 detects the abnormal opening of the door in the parking state. When a detection signal is output from at least one of the sensors 33 to 35, the vehicle abnormality information detection unit 31 notifies the surroundings of the vehicle BD by self-defense, for example, by flashing light or a warning sound such as a buzzer. At the same time, a signal indicating an abnormality of the vehicle BD is transmitted to the control unit 41 in the DSRC in-vehicle device 40 and transmitted to the communication device 13 of the parking lot management center 10.

  The DSRC in-vehicle device 40 is a wireless device mounted on the vehicle BD. The control unit 41 in the DSRC on-vehicle device 40 has a microcomputer as a main component, and is connected to an RF circuit 42 that performs signal processing of radio waves in the 5.8 GHz band. The control unit 41 (vehicle-side control means) transmits a signal for turning on or off the power of the in-vehicle security system 30 in response to the sleep instruction signal or the wake-up instruction signal from the control device 12 in the parking lot management center 10. . Specifically, the control unit 41 transmits a signal for turning on the power of the in-vehicle security system 30 when the stored amount of the battery B is greater than a predetermined remaining amount in response to the wake-up instruction signal, When the storage amount of the battery B is less than a predetermined remaining amount, a signal for turning off the power of the in-vehicle security system 30 is set.

  Next, the operation of the embodiment configured as described above will be described with reference to FIGS. In FIGS. 2 to 6, transmission and reception of communication data among the parking lot management center 10, the DSRC roadside device 20, the in-vehicle security system 30, and the DSRC in-vehicle device 40 are shown in time series.

  First, the case where the vehicle BD enters the parking lot PK and parks in the predetermined parking space [1] will be described. In this case, as shown in FIG. 2, the vehicle BD is detected by the human body detection sensor 22 (M101), and the control unit 21 in the DSRC roadside machine 20 sends the roadside machine number corresponding to the parking space [1] together with the detection signal. [1] is transmitted to the control device 12 in the parking lot management center 10. In response to this, the control device 12 transmits a wake-up instruction signal to the control unit 21 in the DSRC roadside machine 20 corresponding to the parking space in the vicinity of the parking space [1]. In connection with this, the control part 21 in each DSRC roadside machine 20 transmits a wake-up instruction signal to the control part 41 in the DSRC onboard equipment 40 of a corresponding parked vehicle.

  In a state where the DSRC on-vehicle device 40 is in the normal mode, mutual authentication is performed between the control unit 41 in the DSRC on-vehicle device 40 and the control unit 21 in the DSRC roadside device 20. As a result, by confirming that the devices are not unauthorized, unauthorized acts such as impersonation using a fake DSRC roadside device can be prevented. After the mutual authentication is completed, the vehicle information such as the vehicle number, the vehicle type, the owner, etc. stored in the IC card in the DSRC in-vehicle device 40 is notified to the control device 12 in the parking lot management center 10 to register the vehicle. Done. It should be noted that mutual authentication is not performed again on the surrounding parked vehicles for which mutual authentication has already been completed.

  When the in-vehicle security system 30 detects the key lock 32 of the vehicle BD (S101), the in-vehicle security system 30 is turned on (S102). Then, a power-on (security ON) signal of the in-vehicle security system 30 is transmitted from the DSRC in-vehicle device 40 to the control device 12 through the DSRC roadside device 20. Thereafter, the status of the vehicle BD is periodically transmitted to the control device 12, and if there is no abnormality in the vehicle BD, regular communication with the content of no abnormality is performed. In addition, since the person who got off the vehicle BD is detected by the human body detection sensor 22 at the beginning when the power source of the in-vehicle security system 30 is turned on, the communication content of the DSRC roadside device 20 is detected by the human body detection sensor 22. A signal to represent is included.

  When a person leaves the vehicle BD and is no longer detected by the human body sensor 22, the communication content without abnormality includes a signal without detection instead of a signal with detection. From this point, counting by the timer 12a of the control device 12 in the parking lot management center 10 is started (P101), and when regular communication without abnormality continues for a preset time (P102), the control device 12 A sleep instruction signal is transmitted to the DSRC in-vehicle device 40 via the roadside device 20. In response to the sleep instruction signal, the control unit 41 in the DSRC on-vehicle device 40 transmits a signal for turning off the power source of the in-vehicle security system 30, and then shifts from the normal operation mode to the sleep mode with low power consumption (C101). ). The above-described signal transmission / reception is performed for each nearby parked vehicle.

  As described above, when a state in which no abnormality occurs in the vehicle BD continues for a predetermined time, the vehicle-mounted security system 30 is turned off and the DSRC vehicle-mounted device 40 enters the sleep mode, so that the safety of the vehicle BD is ensured. In this state, reduction in power consumption of the battery B can be suppressed. In addition, the sleep instruction from the control device 12 is performed after the mutual authentication described above is completed. For this reason, after the mutual authentication is completed, the route through which the instruction from the control device 12 is transmitted to the DSRC on-vehicle device 40 is guaranteed, so that when the abnormality occurs in the vehicle BD, the power is turned off. The in-vehicle security system 30 can be activated immediately, and the protection by the in-vehicle security system 30 can be effectively performed while reducing the power consumption of the battery B.

  Next, when the human body is detected by the human body sensor 22 corresponding to the parking space [1] in a state where the DSRC on-board device 40 is in the sleep mode and the battery storage amount of the vehicle BD is greater than the predetermined remaining amount. explain. In this case, as shown in FIG. 3, the control device 12 wakes up to the control unit 21 in the DSRC roadside machine 20 corresponding to the parking space [1] in response to the signal detected by the human body sensor 22. An instruction signal is transmitted. In response to this, the control unit 21 transmits a wake-up instruction signal to the control unit 41 in the DSRC on-vehicle device 40. The control unit 41 determines whether or not the storage amount of the battery B is greater than a predetermined remaining amount. Now, since the storage amount of the battery B is greater than the predetermined remaining amount, the power source of the in-vehicle security system 30 is turned on. A signal to be turned on is transmitted (C102). The subsequent flow is the same as that shown in FIG. Similar processing is also performed in the surrounding parked vehicles.

  Next, a case where the human body is detected by the human body sensor 22 corresponding to the parking space [1] in a state where the DSRC vehicle-mounted device 40 is in the sleep mode and the battery storage amount of the vehicle BD is less than the predetermined remaining amount. explain. In this case, as shown in FIG. 4, the control unit 41 in the DSRC vehicle-mounted device 40 does not transmit a signal to turn on the power of the vehicle-mounted security system 30 (C103), and the battery B is insufficient. The signal to represent is transmitted to the control apparatus 12 (P103). And after this transmission, it is set not to respond to the wake-up instruction signal from the control device 12. This prevents the battery of the vehicle BD from running out.

  In response to the signal indicating that the remaining amount of battery B is insufficient, control device 12 registers vehicle BD as a vehicle that cannot wake up. The parking lot management center 10 can lay a special monitoring system for the vehicle BD based on the registration of the vehicle BD that cannot wake up. As a result, even if the power source of the in-vehicle security system 30 is turned off, the parking lot management center 10 effectively protects the vehicle BD from illegal activities.

  Next, a case will be described in which an abnormality occurs in the vehicle BD in a state where the DSRC on-vehicle device 40 is in the sleep mode and the battery storage amount of the vehicle BD is larger than a predetermined remaining amount. In this case, as shown in FIG. 5, the control device 12 wakes up to the control unit 21 in the DSRC roadside machine 20 corresponding to the parking space [1] in response to a signal with detection by the human body sensor 22. The instruction signal is transmitted, and the control unit 21 transmits a wakeup instruction signal to the control unit 41 in the DSRC on-vehicle device 40. Receiving this, the control part 41 transmits the signal which turns on the power supply of the vehicle-mounted security system 30 (C102).

  As described above, the vehicle abnormality information detection unit 31 in the in-vehicle security system 30 notifies the surroundings of the vehicle BD by, for example, flashing light or a warning sound such as a buzzer, according to the detection signals of the sensors 33 to 35. Defend yourself. At the same time, the vehicle abnormality information detection unit 31 transmits an abnormality signal of the vehicle BD from the DSRC in-vehicle device 40 to the control device 12 via the DSRC roadside device 20 and to the communication device 13 in the parking lot management center 10 separately. To do. Based on such information, the guard of the parking lot management center 10 can check the periphery of the vehicle BD through the monitor 11 and can visit the parking space [1] to investigate the periphery of the vehicle BD in detail. In addition, when there is an abnormality in the vehicle BD, it is possible to notify the owner of the vehicle BD through a mobile phone and notify that the vehicle BD will return immediately.

  Next, the case where the vehicle BD exits from the parking lot PK in a state where the DSRC vehicle-mounted device 40 is in the sleep mode and the battery storage amount of the vehicle BD is larger than a predetermined remaining amount will be described. In this case, as shown in FIG. 6, the control device 12 controls the control unit in the DSRC roadside machine 20 corresponding to the parking space [1] in accordance with the detection signal of the owner of the vehicle BD by the human body detection sensor 22. The wakeup instruction signal is transmitted to 21, and the control unit 21 transmits the wakeup instruction signal to the control unit 41 in the DSRC on-vehicle device 40. In response to this, the control unit 41 transmits a signal for turning on the power of the in-vehicle security system 30. When the key lock 32 is unlocked normally (S104), a power-off (security OFF) signal of the in-vehicle security system 30 is transmitted from the DSRC in-vehicle device 40 to the control device 12 via the DSRC roadside unit 20. Thereby, the monitoring system of the vehicle BD by the parking lot management center 10 is canceled.

  In the above embodiment, when a vehicle, a person, or the like is detected by the human body detection sensor 22, the control device 12 adds the DSRC roadside machine 20 having the detected human body detection sensor 22 to the surrounding DSRC roadside machines. 20 is configured to transmit a wake-up instruction signal. As a result, even if an inexpensive sensor that detects not only a person but also a moving body such as a vehicle is used as the human body detection sensor 22, the vehicle can be effectively protected from illegal activities. However, the present invention is not limited to this. For example, a human body sensor that can accurately detect only a person is used, and a wakeup instruction signal is transmitted only to a DSRC roadside machine having a human body sensor that has been detected. May be.

  Moreover, in the said embodiment, although it comprised so that the control apparatus 12 in the parking lot management center 10 could transfer information between the control parts 41 in the DSRC onboard equipment 40 via the DSRC roadside machine 20, For example, the control unit in each DSRC roadside machine may be configured and implemented so as to fulfill an intelligent function as a control device in the parking lot management center.
