Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a device that automatically transmits information for prompt recovery of a vehicle when the vehicle is stolen.
The present invention relates to a vehicle information transmitting device that automatically photographs and transmits a scene inside or outside a vehicle when a vehicle is stolen.

(Prior Art) Conventionally, in order to prevent vehicle theft, the first step was to improve the door lock,
Improvements have been made to power windows, and recently, when a door or window is opened without a code being entered, or when abnormal vibrations are detected in the window, an alarm is emitted on the vehicle or an alarm is transmitted wirelessly. An anti-theft device has been proposed to prevent theft.Secondly, even if a thief were to enter the vehicle, he or she would have to attach the appropriate key to the engine key switch unit (key cylinder) and turn the key. Mechanisms or electrical locking systems have been proposed that would allow the engine to start if the engine is not activated or if a predetermined code is not electrically transmitted or entered, but also locks the steering wheel from rotation.

(Problems to be Solved by the Invention) However, there are cases where a vehicle is broken into by breaking a door lock or a window, and also by breaking the engine key switch unit or being pulled into the unit. The direct connection of the ignition system power line to the battery, which is one of the electrical wires installed, can make the vehicle vulnerable to theft. Vehicle elements related to vehicle running are connected to the ignition system power line, so when the ignition system power line is connected to the battery, the vehicle can be driven in the same way as when the owner is driving it. can. Once the thief starts driving the vehicle, it is very difficult to determine the whereabouts of the vehicle and the culprit, and it takes a lot of effort to search and recover the stolen vehicle, and this effort may be wasted. be.

An object of the present invention is to facilitate the identification of a culprit and/or the location of a vehicle when a vehicle is stolen.

(Structure of the Invention) (Means for Solving the Problems) In order to achieve the above object, the vehicle information transmitting device of the present invention includes: a first detection means for detecting rotation of a wheel; a second detection means for detecting an electrical connection to the battery; a third detection means for detecting whether the electrical connection is a regular connection preset in the vehicle; in the vehicle;
an imaging means for photographing at least one of the outside and generating an image signal; a transmitting means for wirelessly transmitting the image signal; and a second detecting means detecting electrical connection and a third detecting means detecting no electrical connection. image signal transmission control means that energizes the imaging means and the transmission means to transmit an image signal when the first detection means detects rotation of the wheel while the vehicle is in the vehicle.

(Function) When connecting the ignition system power line to the on-vehicle battery, the official method is to insert the engine key into the engine key switch unit (key cylinder) of the vehicle, using an owner-driver as an example.・Enter the code into the vehicle using the code transmitter.

That is, the owner-driver operates some type of hardware on the vehicle or enters a code into an input board or card reader or radio receiver on the vehicle.

The third detection means detects the presence or absence of such an operation or input. Therefore, when the condition is normal, the second detection means detects the electrical connection of the ignition system power line to the on-vehicle battery, that is, the ignition is turned on.

While detecting the operation or input, the third detection means has already detected the presence of the operation or input.

However, while the second detection means detects that the ignition is on, the third detection means detects "No r" (abnormal ignition on; the ignition system power line is connected to the battery without the above operation or input. (It is also possible that there is an abnormality in the connection means that turns on/off between the line and the on-vehicle battery, and there may also be an abnormality in the third detection means), and when the first detection means detects the rotation of the wheel, an image signal A transmission control means energizes the imaging means and the transmission means to transmit an image signal. This allows inside the vehicle.

It can be displayed in play and/or printed out and recorded on a video recorder if desired.

Therefore, if a thief connects the ignition power line to the vehicle's on-board battery and rotates the wheels (driving the vehicle using engine power, or towing the vehicle even when the engine is stopped) without performing the above-mentioned operations or inputs that should be performed by the owner-driver,
Video information is automatically transmitted, and in a mode in which the inside of the vehicle is captured by the imaging means, an image of the thief is sent to the receiving side, and in a mode in which the outside of the vehicle is captured, the scenery outside the vehicle (near the road) is transmitted to the receiving side. This makes it easier to identify the thief or the location of the vehicle.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

A rotor ROR of an engine key switch unit (key cylinder') KSU is connected to the vehicle battery BAT. The key cylinder KSU is a key detection contact KD for detecting the attachment of a key (11 in the driver's possession), an accessory contact for connecting the power supply circuit of accessories such as a radio to the battery BAT, AC, engine ignition circuit, and other vehicles. It has an ignition contact IG for connecting a power supply circuit of an electric device or an electric circuit related to running to the battery BAT, and a starter contact ST for connecting the starter motor to the battery BAT.

In this embodiment, as will be described later, Edg is H (power line IgP is at the battery voltage level) and Edk.

At least one of Eda is L (not at battery voltage).

Moreover, when the wheels are rotating (wheel rotation speed Vs ≧ set value Vr), it is considered as the first abnormality (theft, etc.), and E
When dg is L (power line IgP is not at the battery voltage level) and the wheels are rotating (Vs≧Vr), it is considered as a second abnormality (such as theft), and when the first or second abnormality occurs, the microprocessor 2 energizes the relay driver 9 to close the relay 10 and forward monitoring device 12 . Activation control device for electrical equipment 13. Lamp controller 14. Irradiation angle controller 15. Turn on the power to the facsimile FAX and the car telephone radio WSR (connect the ignition system power line IgP to the battery BAT), and take pictures of the driver's seat (the face of the person sitting in it) and the front of the vehicle with the cameras 21 and 19. The image is transmitted via radio waves.

The power supply circuit 1 that supplies power to the microprocessor 2 includes
Battery voltage is applied via power switch PSW. Therefore, as long as the power switch PS is closed, the operating voltage is applied to the microprocessor 2 even if no key is attached to the key cylinder KSU. Note that when the power switch PSW is closed, the power-on reset circuit 3 generates a reset pulse, and the microprocessor 2 responds to this to perform an operation reset (start of control operation from initialization).

The vehicle is equipped with a facsimile machine, and its controller (mainly a microprocessor) 17 has a serial data transmission and reception port Ss.

Receive serial data from microprocessor 2 to Sr.

Transmission ports Sr and Ss are connected.

In this embodiment, the facsimile fax is operated in an image reception mode in which an image of a document from another station is received via a normal telephone line (voice communication line), an image transmission mode in which an image of a document on a vehicle is sent to another station, and an image transmission mode in which an image of a document on a vehicle is transmitted to another station. In addition to a copy mode for duplicating an image of an original document, and a text reception mode for receiving text (character code) data from the sender via a data communication line and reproducing the text, for the implementation of the present invention ,
It is designed to operate in an external image writing mode, an external image reproducing mode, and a memory image transmitting mode.

In image reception mode, facsimile FAX is.

If the address name (telephone number) received by the car telephone radio WSR and sent to the controller 17 via the 1-line controller 26 and modem 25 is that of its own station, the controller 17 transmits a reception protocol to the modem 25. Under the control of the controller 17, the modem 25 decompresses the communication signal received by the radio WSR into image compression encoded data (compressed data) and stores it in the buffer memory 31. The decoder 32 reproduces the accumulated data into image data in synchronization with the operation of the decoder 32, stores it in the buffer memory 29, reads it out in synchronization with the operation of the printer 33, and prints it. Out (image playback).

In image transmission mode, facsimile fax.

Call the partner station specified on the operation/display board 27 (also specifying whether or not to use automatic dialing) using a normal dial alcohol or automatic dialing using the automatic dialing device 24, connect the communication line, and scan the original image using the scanner 28. It reads and generates image data, which is stored in the buffer memory 29.
The data is stored in the buffer memory 2, read out from the memory 29 in synchronization with the operation of the encoder 30, compressed and encoded, and then stored in the buffer memory 2.
1 and transmits it in synchronization with the other party using the modem 25.

In the copy mode, the facsimile FAX reads the original image with the scanner 28 to generate image data, stores this in the buffer memory 29, reads it out in synchronization with the operation of the printer 33, and provides it to the printer 33. Print out a copy of the original.

In the text reception mode, the facsimile FAX stores received text data in the buffer memory 31 and supplies it to the character generator (ROM storing image data representing character images) 34 in a predetermined sequence, so that the generator 34 generates data. When the image data for one frame is written to the memory device 36, the image data is read out from the frame memory device 36 and stored in the buffer memory 29. The stored data is synchronized with the operation of the printer 33, and the data in the memory 29 is given to the printer to print out a text image.

In the external image writing mode, the facsimile FAX specifies the input/output gate 35 as a connection for writing the output image data of the switching gate 16 to the frame memory device 36, and provides the image data to the frame memory device 36 and the switching gate. The image data output by the switching gate 16 is written into the frame memory device 36 by exchanging control signals and timing signals with the source (the forward monitoring device 12 or the energizing control device 13 of the electric device).

In the external image reproduction mode, the facsimile FAX specifies the input/output gate 35 to be connected to supply the image data read from the memory device 36 to the buffer memory 29, and transfers the image data read from the frame memory device 36 to the buffer memory 29. The image data stored in the memory 29 is stored at one time and synchronized with the operation of the printer 33, and is then given to the printer and printed out.

In the memory image transmission mode, the facsimile FAX specifies the input/output gate 35 as a connection for supplying the image data read from the memory device 36 to the buffer memory 29.
The image data read from the frame memory device 36 is stored in the buffer memory 29 and provided to the encoder 30 in synchronization with the operation of the encoder 30, and the compressed and encoded image data, that is, the encoded data, is stored in the buffer memory 29. 31, and then synchronizes with the operation of the sending destination and stores it in memory 3.
1 encoded data is transmitted to the destination.

The above-mentioned "external image writing mode" and "memory image sending mode" can be instructed to the controller 17 by key operations on the operation/display board 27, and the microprocessor 2 can also control its serial sending port Ss and serial receiving mode. Using the boat Sr, mode instruction data is serially transmitted to the controller 17 to instruct the controller 17.

The control operation of the microprocessor 2 will be explained with reference to FIGS. 2 and 3. First, refer to FIG.

When the power switch PSW is closed, the power supply circuit 1 supplies a predetermined voltage to the microprocessor 2 and the power-on reset circuit 3.
When the power is turned on, the microprocessor 2 (hereinafter referred to as CPU 2) executes initialization (subroutine 1: hereinafter, the words "step" and "subroutine" will be omitted in parentheses). In this initialization (1), the CPU 2 sets internal counters, registers, flags, timers, etc. to the contents assigned in the standby state, and sends signals or data at the level assigned to the standby state to the output port. Set, and clear the input port once. With this initialization (1), output port Ao is set to H (forward monitoring device 12, etc. not energized), and output port ph is set to L (relay 10 is not energized).
open) is output.

After completing the initialization (1), the CPU 2 latches and energizes the input port, reads the input signal at that time, and activates the switch STS to instruct (instruct by closing) to stop transmitting an abnormality (theft, etc.) response image. Check if is closed. If this is open, abnormality detection (3) is performed.

To explain the details of abnormality detection (3) with reference to FIG. 3, first, the analog voltage Vs indicating the vehicle speed applied to the A/D conversion input port ADc is converted into digital data (wheel speed Vs). (21), and checks whether the output Edg of the constant voltage circuit 37g is H (the ignition system power line IgP is connected to the battery BAT) (22), and if it is L, the wheel It is checked whether the speed Vs is greater than or equal to a predetermined value Vr (the wheels are rotating) (23). If it is above Vr, the wheels are rotating even though the ignition is off (the engine is not rotating), so it is assumed that there is an abnormality (the vehicle is being towed, etc.), and the contents of the register ABN are cleared ( = vehicle running) (24), and the abnormality processing of steps 4 to 17 in FIG. 2 is executed. When the wheel speed Vs is less than the predetermined value Vr, the engine is stopped and the wheels are stopped, which is considered to be normal, so the process returns to step 2.

With the check in step 22, the output E of the constant voltage circuit 37g
If dg is H, check whether the outputs Edk and Eda of the constant voltage circuit 37 and 37a are H.
．． 26), either one is L (power line IgP
is connected to the battery BAT, but the contacts KD and/or AC are not connected to the battery BAT; there is an abnormality inside the vehicle), and check whether the wheel speed Vs is equal to or higher than the predetermined value Vr27). If so, the vehicle is running (there is an abnormality inside the vehicle and the vehicle is running), so register ABN.
is cleared (=the vehicle is running) (24), and the abnormality processing of steps 4 to 17 in FIG. 2 is executed. If the wheel speed Vs is less than the predetermined value Vr, there is an abnormality inside the vehicle, but the vehicle is not running, so information indicating this (abnormal n: vehicle is not running, but the KSU is abnormal) is written to the register ABS. (28), and the abnormality processing of steps 4 to 17 in FIG. 2 is executed.

To summarize here, due to the above-mentioned "abnormality detection" (3), when the power line IgP is not at the battery voltage level (the engine is stopped) but the wheels are rotating,
Clear register ABN and follow steps 4 to 17 in Figure 2.
Proceed to the abnormality processing shown in Figure 2 and clear the register ABN even when the power line IgP is at the battery voltage level and the battery voltage is not applied to the contacts KD and/or AC and the wheels are rotating. Proceed to abnormality processing in steps 4 to 17, and when the power line IgP is at the battery voltage level and the battery voltage is not applied to the contacts KD and/or AC and the wheels are stopped, register AB
``Abnormality Ink (vehicle is stopped)'' is written in N, and the process proceeds to steps 4 to 17 in FIG. 2 for abnormality processing.

Proceeding to the abnormality processing in steps 4 to 17, first outputs H to the output port ph (4). In response to this, the relay driver 9 connects the contacts of the relay 10. Therefore, even if the power line IgP is not connected to the battery BAT, the former is connected to the latter via the contact piece of the relay 10. The aforementioned forward monitoring device 12. Electric device energization control device 13° lamp controller 14. Irradiation angle controller 15, facsimile FAX and car telephone radio WS
The power supply circuit of R is powered on when the power supply line IgP is connected to the battery BAT.

Next, the CPU 2 switches the output of the output port AO from H to L (5), and in response, the illumination angle controller 1
5 activates the illumination angle adjustment mechanism 22 to raise the headlamp 23, and the lamp controller 23 activates the headlamp 23.
is energized (energized to emit light), and while receiving this L, the lamp controller 23 automatically adjusts the illumination angle corresponding to the inclination angle of the vehicle body. The forward monitoring device 12 outputs the image data obtained by converting the video signal of the camera 21 into a binary value and the control signals such as the read synchronization signal to the switching gate 16.
Image data obtained by binarizing the video signal of 9 and control signals such as a read synchronization signal are output to the switching gate 16.

The CPU 2 then transmits destination data and call instruction data to the controller 17. The destination data indicates a telephone number (for example, a home facsimile number, a contracted security company's facsimile number, etc.) registered in advance by the vehicle owner. In response, the controller 17 causes the automatic dialing device 24 to make a call (dialing) (6). When the other party goes off-hook (equivalent to picking up the handset), the controller 17 exchanges protocols with the other party, establishes a facsimile transmission/reception connection, and notifies the CPU 2 that transmission is possible.
6, a gate control signal designating "output of video information of camera 21" is output, and data instructing controller 17 to perform the "external image writing mode" described above is transmitted. In response, the controller 17 controls the input/output gate 3.
5 and the frame memory device 36 to write the output image data of the switching gate 16, and the memory device 5 instructs the frame memory device 36 to write the output image data of the switching gate 16. 36 notifies, the controller 17 sends data indicating completion of writing to the CPU 2 (7).

When the CPU 2 receives the write end, in response to this, the CPU 2 transmits data specifying the "memory image transmission mode" described above to the controller 17.

The controller 17 is now in "memory image transmission mode".
When the transmission of one frame of image data in the frame memory device 36 to the destination is completed, data indicating the completion of frame data transmission is transmitted to the CPU 2 (8).
).

As a result of the above, the image (1 frame) of the driver's seat (the face of the seated person) captured by the camera 21 has been transmitted to the other party.

When the CPU 2 receives data indicating the end of frame data transmission from the controller 17, it checks whether the switch STS is closed (9), and if the switch STS is open, the contents of the register ABN indicate "abnormal InJ". (The vehicle is not running) (10), r abnormal InJ.

The process advances to subroutine 14 of "abnormality detection". The contents of this subroutine 14 are the same as the contents of the above-mentioned "abnormality detection" subroutine 3. Last time (
Similar to the detection in step 3), when an abnormality ("abnormal InJ") is detected, the "external image writing mode" (7) and the "memory image transmitting mode" (8) are executed again.

Due to the above operation, "while detecting abnormal InJ,
One frame of image data captured by the camera 21 is repeatedly transmitted to the other party at a predetermined period.

When someone is seated in the driver's seat, an image of that person's face is sent to the other party. If the destination is a facsimile, an image of the face will be printed out online. The other party is a monitoring station equipped with a CRT display and a video recorder.

It is displayed on a CRT and recorded on a video recorder.

Now, when the contents of the register ABN are checked in step 10, if it is not abnormal InJ, the switching gate 16 transfers the image data of the camera 19 to the memory device 3.
6, write the data of one frame image taken by the camera 19 to the frame memory device 36 in the same manner as in the above-mentioned subroutine 7 (11), and then in the same way as in the above-mentioned subroutine 8. The image data in the memory device 36 is transmitted to the other party (12), and it is checked whether the switch STS is closed (13). If the switch STS is open, the "abnormality detection" subroutine 14 is executed.
Proceed to "Abnormality Detection J (14)". If an abnormality ("No abnormality InJ") is detected as in the previous detection (3), "External image write mode" (7) and "Memory image transmission mode J (8) , r external image writing mode J (11) and memory image transmitting mode J (12), the image data of l frames photographed by camera 21 and the image data of camera 19 are recorded at a predetermined period. One frame of image data is alternately transmitted to the other party.If someone is sitting in the driver's seat, an image of that person's face and the scene in front of the vehicle are alternately transmitted to the other party. If the recipient is a fax machine, images of the face and the scene in front of the vehicle will be printed out alternately online.If the recipient is a monitoring station equipped with a CRT display and video recorder, those images will be printed out online. It is displayed on a CRT display and recorded on a video recorder.

While sending image data as above.

When the switch STS is closed, the CPU 2 detects this in step 9 or 13 and instructs the controller 17 to "off-hook" (return the handset; disconnect the communication line). The controller 17 then disconnects the communication line (15);
CPU2 then switches to output port AottH (1
6). As a result, the forward monitoring device 12 stops energizing the camera 19, the energizing control device 13 of the electric device turns off the lighting lamp 20 and stops energizing the camera 21, and the lamp controller 14 stops energizing the headlamp 23. The illumination angle controller 15 retracts (stores) the illumination angle adjustment mechanism 22.
to energize. However, when these electrical devices are instructed to be energized by their own operation switch, even if the signal at output port A becomes H, they will not operate according to the instruction of the operation switch (including energization). ) to continue. this is,
This is because the output port A and the output port are provided to the internal wiring of each of the devices in a logical sum with the instruction (L) of the operation switch of each device.

CPU2 has output port A. After a predetermined period of time (sufficient time for the headlamp to return from the standing position to the retracted position) after switching the output from L to H, the output port ph is returned from H to L, thereby energizing the relay driver 9. The relay 10 stops and the contact piece of the relay 10 is opened. At this time, the power line IgP is connected to the battery BA by other means (for example, rotor ROR).
If it is not connected to T, the power line IgP will be disconnected from the battery BAT, and the car phone radio WSR, facsimile FAX, and forward monitoring system will be disconnected. 12 (and camera 19)
.

energization control device 13) of the electrical device, (camera 21) lamp controller 14, and illumination angle controller 15
The power supply to the power supply circuit is cut off.

Note that when the CPU 2 detects normality in the subroutine 14, it similarly executes steps 15 to 17.

Wheel speed detection circuit 6 and relay driver 9 are connected to power supply circuit 1
When the microprocessor 2 is supplied with power and an operating voltage is applied to the microprocessor 2, the required voltage is similarly applied.

To stop the transmission of image data in response to the abnormality detection described above, the switch STS may be closed.

When the lees switch 5TSt-duck is set, the CPU 2 detects this in step 9 or 13 as described above, and switches to step 15.
~17, the transmission is stopped.

Note that if the switch STS is closed when initialization (1) is executed, the CPU 2 transmits text data expressing an automatic dialing instruction and a warning to the controller 17. When controller 7 receives this, it sends ACK to CP.
Convert the text data to image data using a character generator and write it to the buffer memory, call the destination designated for automatic dialing using the automatic dialing device 24, and send the image data in the buffer memory 29 to the destination. Then, when the transmission is finished, the line is disconnected (18).
When the CPU 2 receives the ACK signal (19), it checks whether the switch STS is open or closed (20), and if it is closed, it remains on standby.

When the switch STS is opened, proceed to initialization l.

Execute the following steps in abnormality detection (3) described above.

By the control operation of the CPU 2 explained above, the switch P
When SW is closed and switch STS is open, the voltage of the ignition system power line IgP is below the specified value (Edg
is L (Igp is not connected to BAT) and the wheel 4 rotates, the image taken by the camera 21 and the image taken by the camera 19 are stored in advance in the CPU 2. Controller 1
7 or automatic dialing device! The message is sent by wireless telephone to the communication destination registered in 24.

Therefore, a person attempting to steal a vehicle may push the vehicle without starting the engine (without putting the key in the key cylinder), or
When the wheels are rotated, an image of the face of the person sitting in the driver's seat (if any) and the scene in front of the vehicle are automatically transmitted to the communication destination.

When the switch PSW is closed and the switch STS is open, and the voltage of the ignition system power line IgP is above a predetermined value (Edg is H; IgP is connected to BAT), the contact KD and/or the contact AC of the key cylinder KSU is voltage is less than a predetermined value (Edk or Eda is L),
When the wheel is rotating, the camera 21
The image taken by the camera 19 and the image taken by the camera 19 are transmitted to one communication destination by wireless telephone. When the wheels are not rotating, only the image taken by the camera 21 is transmitted to the communication destination.

Therefore, if a person attempting to steal a vehicle illegally enters the vehicle and connects the ignition system power line IgP to the battery BAT by illegal means, the person sitting in the driver's seat will see the face of the person sitting in the driver's seat before the vehicle starts. The image is sent to the destination via wireless telephone. When the vehicle is started, an image of the face of the person sitting in the driver's seat and the scene in front of the vehicle are automatically sent to the communication destination.

At the communication destination, for example, in the mode of online reception and printing by facsimile, the face of the person sitting in the driver's seat is displayed on every screen (one page).

Alternatively, this and the scene in front of the vehicle are printed out alternately on each screen. In correspondence, therefore.

If the vehicle is stolen, the face of the person sitting in the driver's seat can be used to identify the culprit. The scene in front of the vehicle is
It can be used to determine the location of a vehicle.

〔Effect of the invention〕

As described above, according to the vehicle information transmitting device of the present invention.

Since image data of the driver of the stolen vehicle or the scene in front of the vehicle can be automatically obtained from a distance from the vehicle, it becomes easy to identify the culprit or determine the current location of the vehicle.
