Description

  The present invention relates to a parking lot monitoring system that monitors a vehicle so as not to be stolen in a parking lot, particularly a parking lot that accepts a large number of vehicles.

Many recent automobiles give an alarm when a person other than the owner tries to open a locked door, or have an immobilizer that cannot start the engine other than a regular key. There are also retrofitting devices marketed under the names “vehicle abnormality monitoring alarm” and “automobile burglar alarm”. In these alarm devices, the main body device mounted on the automobile monitors the following actions with various sensors.
A. Theft of the car itself Theft of tire wheels and license plates Theft of money and electrical components in the car or trunk (car vandalism)
When a theft or destruction is detected, the main unit or its accessories emits an alarm sound or turns on a warning light to intimidate or repel the actor.

  Some alarm devices are combined with an “answerback remote control”. When a change is detected, the main body apparatus transmits a message to that effect to the answerback remote controller carried by the vehicle owner. As a result, the owner knows that his / her car has changed, and instructs the main unit to intimidate / repel or notify the surroundings, or reports to the security company or police. Measures can be taken.

Many systems have been proposed for monitoring a large number of vehicles in a parking lot and notifying the owner, a parking lot manager, a security company, etc. when any of the vehicles changes. For example, in Patent Document 1, when an intrusion or movement of a vehicle occurs, an in-vehicle sensor-type transmitter mounted on the vehicle transmits an abnormality detection signal, and the abnormality detection signal is received by the security controller. A security system that reports abnormalities is described. Patent Document 2 describes a vehicle anti-theft system that performs mutual communication between a vehicle-mounted device and a management station using narrow-area wireless communication means to monitor each other's state.

  There is also a parking lot monitoring system that monitors the entire parking lot with a camera, but if it is cleverly hidden behind the blind spot of the camera and acting, the surveillance becomes powerless and allows the crime to be established. At that point, the monitoring system that installs the monitoring means for each vehicle entering the parking lot can detect the vibration and sound with the sensor and know the abnormality, so it eliminates the blind spot of the camera and effectively performs criminal activities Can be contained. Further, when the vehicle is moved out of the parking lot, the monitoring means can be informed of the current position, or when the vehicle enters the parking lot, the monitoring means can be used as a warehousing permit.

  Now, when monitoring a parking lot by mounting monitoring means on each vehicle, the following problems occur. If a commercially available answer back remote control type alarm device is used, the main body is mounted on the vehicle, and the answer back remote control is carried by the vehicle owner, the system can be constructed most simply. In addition, when a criminal act is about to be performed, how to deal with it can be left to the vehicle owner's own decision making, so it is possible to omit a resident parking lot manager. However, since the communicable distance between the main body and the answer back remote control is only a few hundred meters, the vehicle owner becomes unsupervised when the vehicle owner is further away.

  By installing a dedicated vehicle-mounted monitoring means on the vehicle and receiving the radio waves from the vehicle at a dedicated wireless station, and then notifying the vehicle owner via the telephone network or the Internet, the vehicle owner can be in a remote location. Can maintain the monitoring state. However, this method is costly for the development of dedicated in-vehicle monitoring means and functional maintenance after development.

  The present invention has been made in view of the above points, and in a parking lot monitoring system in which a monitoring means is mounted on each vehicle entering the parking lot, data can be collected from the monitoring means at a low cost, and remote The purpose is to provide a system that can notify the vehicle owners on the ground.

  (1) In order to achieve the above object, a parking lot monitoring system according to the present invention is mounted on a vehicle that has entered the parking lot, and when an abnormality occurs in the vehicle, the in-vehicle monitoring unit that wirelessly transmits a warning signal; A portable unit that receives a warning signal transmitted from an in-vehicle monitoring unit and converts it into a warning display that can be perceived by a human, and is installed in a communicable area of the in-vehicle monitoring unit, A storage for individually storing the portable unit belonging to the vehicle in a storage cell, a sensor provided in each storage cell of the storage for detecting an alarm display of the stored portable unit, and detection contents of the sensor It is characterized by comprising transmission means for converting into communication contents for public communication network and transmitting to a predetermined communication terminal.

  According to this configuration, the mobile unit that receives the warning signal transmitted from the in-vehicle monitoring unit is stored in the storage cell of the storage unit installed in the communicable area of the in-vehicle monitoring unit, and the mobile unit detected by the sensor in the storage cell. Since the alarm display of the unit is converted into the communication content for the public communication network and transmitted to a predetermined communication terminal, it is possible to report an abnormality occurring in the vehicle wherever the vehicle owner is. In addition, since the combination of the in-vehicle monitoring unit and the portable unit can use a commercially available answerback remote control type alarm device as it is, development cost is unnecessary. Therefore, it is possible to construct a low-cost parking lot monitoring system as a whole.

  (2) Further, in the parking lot monitoring system having the above configuration according to the present invention, when the in-vehicle monitoring unit does not detect any change in the vehicle, the transmission unit transmits the fact to the communication terminal at a predetermined timing. It is characterized by that.

  According to this configuration, since the owner is actively notified that no abnormality has occurred in the vehicle, the owner can operate with peace of mind away from the vehicle.

  ADVANTAGE OF THE INVENTION According to this invention, the parking lot monitoring system which can send a warning signal to an owner far exceeding the communicable area can be provided, making the answer back remote control type alarm device easy to obtain as a main body.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a parking lot monitoring system.

  In the figure, reference numeral 1 denotes a parking lot, and 10 denotes a vehicle stored therein. “Vehicle” includes a motorcycle and the like. Each vehicle 10 is equipped with an in-vehicle monitoring unit 20. The in-vehicle monitoring unit 20 detects abnormalities occurring in the vehicle 10 with various sensors and transmits a warning signal to the portable unit 21 wirelessly. A commercially available answer back remote control type vehicle abnormality monitoring alarm device or vehicle burglar alarm device is used for the in-vehicle monitoring unit 20 and the portable unit 21. The model selection is left to the owner of the vehicle 10.

  Typical sensors included in the in-vehicle monitoring unit 20 are a sound pressure sensor, a Doppler sensor, a tilt vibration sensor, and the like. The sound pressure sensor detects a sound of opening the door of the vehicle 10, a sound of breaking a window glass, a sound when a strong impact is applied to the vehicle body, and the like. The Doppler sensor detects that a person approaches the vehicle 10, hesitates around, or enters the vehicle. The tilt vibration sensor detects that the vehicle 10 is moved by the tow truck. The in-vehicle monitoring unit 20 includes all or one of the above three types of sensors according to the specifications for each model, and also includes other sensors depending on the model.

  The portable unit 21 is a so-called answer back remote controller. When the portable unit 21 receives a warning signal from the in-vehicle monitoring unit 20 that forms a pair, the portable unit 21 converts the warning signal into a warning display that can be sensed by humans, such as sound, light, and vibration. Since the answerback remote control can be additionally purchased, two of them are prepared together with the original one, and one is carried by the vehicle owner, and the other is managed by the parking lot monitoring system. The managed mobile unit 21 is stored in a locker-type storage 30.

  The storage 30 is not necessarily installed in the parking lot 1. The portable unit 21 may be placed anywhere as long as it can receive radio waves from the in-vehicle monitoring unit 20. In consideration of safety, it is preferable to install in a building with better security than the parking lot 1.

  The storage 30 has a large number of cells 31 in which the mobile units 21 are stored one by one. Each cell 31 is provided with a sensor for detecting an alarm display issued by the mobile unit 21 therein. In the figure, reference numeral 32 denotes a sound sensor, which can be constituted by a microphone, for example. Reference numeral 33 denotes an optical sensor, which can be configured with a photoelectric conversion element such as a phototransistor, for example. A vibration sensor 34 is provided so as to be in close contact with the portable unit 21.

  Appropriate shielding treatment is performed between the cells 31 so that the alarm display from the portable unit 21 does not affect the sensors of the other cells 31. The cells 31 may be isolated from each other. In addition, the outer shell of the storage 30, the door of the cell 31, its locking device, and the like are given sufficient strength so that the internal portable unit 21 is protected even in the unlikely event of an attack. However, there is a way to send radio waves to the mobile unit 21. Further, a power supply for supplying power to the mobile unit 21 housed therein is prepared inside each cell 31. Thereby, it becomes unnecessary to worry about the consumption of the battery built in the portable unit 21.

  When the sound sensor 32, the optical sensor 33, and the vibration sensor 34 detect the alarm display of the portable unit 21, the sound sensor 32, the optical sensor 33, and the vibration sensor 34 convert the alarm display into unique signals and transmit them to the control device 40. The control device 40 functions as a transmission unit, converts the detection content of the sensor into communication content for the public communication network, and transmits the communication content to a communication terminal registered in advance by the owner of the vehicle 10. A personal computer 50 or a mobile phone 51 can be used as a communication terminal. Information is transmitted to the personal computer 50 from the local LAN 52 via the Internet 53. Information is transmitted from the Internet 53 to the mobile phone 51 via the mobile phone network 54. Note that the Internet 53 and the mobile phone network 54 are presented as examples of public communication networks, and there are no restrictions on using other public communication networks.

  At a predetermined location of the parking lot 1, information is transmitted to the control device 40, and the next device that is operated by the control device 40 is disposed. The human sensor 41, the projector 42, the speaker 43, and the surveillance camera 44 are it. The human sensor 41 is installed so that a location outside the detection area of the in-vehicle monitoring unit 20, for example, the entrance / exit of the parking lot 1 or the center of the passage is used as the detection area. The necessary number of projectors 42, speakers 43, and surveillance cameras 44 are installed at appropriate locations in the parking lot 1 so that all locations in the parking lot 1 can be exposed to light, heard, and photographed. The It is desirable that the projector 42 and the monitoring camera 44 can be freely changed in direction by remote operation. An image accumulation processing device 45 is attached to the monitoring camera 44.

  An open / close gate 3 is installed at the entrance 2 of the parking lot 1. The gate 3 is also controlled by the control device 40.

  Next, the operation of the parking lot monitoring system will be described. The parking lot 1 of this embodiment is a so-called contract parking lot, and only the contracted vehicle 10 is allowed to enter. In the contract, it is required to purchase a commercially available answer back remote control type vehicle abnormality monitoring alarm device or vehicle burglar alarm device, mount the in-vehicle monitoring unit 20 on the vehicle 10 and leave one portable unit 21. The models of the in-vehicle monitoring unit 20 and the portable unit 21 are registered in the control device 40. In addition, the communication terminal that receives the contact is registered in the control device 40. When the personal computer 50 is selected as the communication terminal, a mail address is registered. When the mobile phone 51 is selected, a telephone number and / or mail address is registered.

  After the contract is established, the administrator issues a wireless IC tag if the contractor wishes. If a wireless IC tag is worn, it will be excluded from the monitoring target in the parking lot 1 and will not cause unnecessary alarms. The wireless IC tag can be carried in the form of a key holder.

  A parking place in the parking lot 1 is designated with the contract of the parking lot 1. Each cell 31 of the storage 30 corresponds to each parking place on a one-to-one basis, and the portable unit 21 deposited from the owner of the vehicle 10 is stored in the cell 31 corresponding to the designated parking place. The storage unit 30 stores as many portable units 21 as the number of contracts.

  The contractor enters the vehicle 10 into a predetermined parking place in the parking lot 1, and then sets the on-vehicle monitoring unit 20 to the function ON state, and removes the engine key and locks the door, and then prepares the parking system. Leave. From here, monitoring of the vehicle 10 is started.

  When the theft vehicle 10 is stolen, the in-vehicle monitoring unit 20 mounted on the vehicle 10 detects an abnormality. The detection mode varies depending on the in-vehicle monitoring unit 20, but in any detection mode, when the vehicle 10 is about to change or is detected to have changed, the in-vehicle monitoring unit 20 wirelessly transmits a warning signal. Send with. The portable unit 21 paired with the in-vehicle monitoring unit 20 receives the warning signal and displays an alarm. The alarm display is converted into respective signals by the sound sensor 32, the optical sensor 33, the vibration sensor 34, and the like, and transmitted to the control device 40. The control device 40 identifies the parking place where the abnormality has occurred and the vehicle 10 parked there depending on which cell 31 the signal has come from.

  The control device 40 converts the detected content transmitted from the sensor into an alarm for communication content (mail or voice) for the public communication network. The alarm is transmitted from the local LAN 52 to the communication terminal (personal computer 50 or mobile phone 51) registered by the contractor who is the owner of the vehicle 10 in which an abnormality has occurred through the Internet 53 and the mobile phone network 54. The received communication terminal is notified by mail or voice. As a result, the contractor can know that the vehicle 10 has changed even in a remote place.

  The control device 40 starts the crime prevention action simultaneously with the incident notification. That is, the light of the projector 42 is applied to the vehicle 10 in which an anomaly has occurred or its surroundings, a warning or intimidating sound is emitted from the speaker 43, and the surveillance camera 44 is photographed at the crime scene. The captured image is stored in the image storage processing device 45 to be useful for a criminal investigation at a later date. The control apparatus 40 notifies a contract security company or the police depending on the case. It is also possible for the contractor to answer back from the communication terminal to control these operations.

  The control device 40 performs not only a change but also a check (health check) that the vehicle 10 is safe, and notifies the contractor. That is, when the in-vehicle monitoring unit 20 does not detect any change in the vehicle 10, the control device 40 transmits that fact to the communication terminal at a predetermined timing. As a result, the contractor can operate with confidence in a place away from the vehicle 10. A contractor who feels troublesome with such a report may register that the report is unnecessary.

  When the contractor leaves the vehicle 10, the function of the vehicle-mounted monitoring unit 20 is canceled by the portable unit 21 that is carried, and the vehicle 10 is boarded after the alarm is stopped. If the wireless IC tag given to the contractor is worn, the alarm can be prevented from occurring.

  Installation of the in-vehicle monitoring unit 20 or wearing of a wireless IC tag can be used as the opening condition of the gate 3. That is, the gate 3 is opened only for the vehicle 10 on which the registered in-vehicle monitoring unit 20 is mounted or the occupant wears the wireless IC tag. Thereby, vehicles other than the contract vehicle can be prevented from entering the parking lot 1.

  The control device 40 has a web server function and provides a home page. The contractor can open the homepage on the Internet 53 and change the telephone number and mail address for receiving the alarm at any time.

  Instead of activating the monitoring camera 44 only when the in-vehicle monitoring unit 20 transmits a warning signal, the monitoring camera 44 can be always in a monitoring state. In this case, the monitoring camera 44 always images the holding area. When the image accumulation processing device 45 processes the image and a suspicious movement is observed, a predetermined crime prevention action, that is, a warning or intimidation by the projector 42 or the speaker 43, a report to the contractor, a contract security company, It can be linked to reporting to the police. Thereby, even if the vehicle-mounted monitoring unit 20 breaks down, a hole is not produced in monitoring.

    Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

    The present invention can be widely used for parking management.
