The operation of the photographing apparatus for a vehicle according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1, when a camera 30 for photographing a traffic accident or a situation around a vehicle is mounted on the vehicle 1, when a vehicle power source (for example, DC12V) is connected, a power supply unit The DC-DC converter 191 in 190 makes the required voltage and outputs it.

The output voltage is supplied to the motor 152 in the film recovery unit 150, filtered through the low pass filters (L2, C13), and then supplied to the portions where power is needed. When the power is supplied by the power supply unit 190, the light emitting diode (LED) is turned on to inform that the power is supplied to the outside.

When the necessary power is supplied by the operation of the power supply unit 190 as described above, the controller 130 performs initialization, and when the initialization operation is completed, the controller 130 searches for the input of the work port to optimally control the photographing apparatus.

In this case, the driver may set the shutter driving interval using the dip switch in the shutter driving interval setting unit 170, and the controller 130 controls the driving interval during the shutter operation in response to the setting.

On the other hand, when the driver inserts the ignition key into the key holder for operation and operates the ignition key in the ON state, the ignition switch SW1 in the ignition switch detection unit 110 is operated in the ON state. do. When the start switch SW1 is operated in an on state, a start detection signal is generated in a high state, and the analog start detection signal generated in this manner passes through the first inverter 111 and the second inverter 112 and is shaped. The digital signal is converted and transmitted to the controller 130.

In the state where the start switch SW1 is operated in the on state, the driver drives, and when an emergency situation (collision, collision situation or other situation) occurs, the driver quickly presses the brake pedal 61 to the maximum. When stepped on the brake pedal 61 as much as possible, the limit switch 63 placed between the leaf spring 62 and the brake pedal 61 is operated in an on state.

When the limit switch 63 is operated in the on state, an emergency situation detection signal is generated, and the emergency situation detection signal generated in this way is transmitted to the third and fourth inverters 121 and 122 in the emergency situation detection unit 120. The digital signal is converted into a digital signal and applied to the controller 130.

The controller 130 determines whether to automatically photograph by combining a signal generated by the start switch detector 110 and a signal generated by the emergency situation detector 120. That is, only when the start switch detection signal is generated as the high signal 1 by the start switch detection unit 110 and the emergency situation detection signal is generated as the high signal 1 by the emergency situation detection unit 120. You decide to shoot.

When the determination is made by automatic photographing as described above, the shutter driver 140 generates a shutter driving signal as a low signal. The shutter driving signal is generated according to the shutter driving interval set by the driver. The shutter driver 140 generates a shutter driving signal (high signal) by operating the photo coupler 141 when the shutter driving signal output from the controller 130 is in a low state. The transistor Q1 operates in a turn-on state by the driving signal. When the transistor Q1 operates in a turn-on state, a driving current flows through the solenoid 142 that operates the shutter, and the solenoid 142 operates by the driving current to operate the shutter added to the camera 130. It will work. This automatically captures the situation around the vehicle.

That is, conventionally, since the camera starts recording only when the driver sends out a voice or operates a separate remote controller, it is impossible to actually photograph a traffic accident or the situation around the vehicle if the driver does not respond immediately after the traffic accident. . It is difficult for a driver of a car in an actual traffic accident to immediately send a voice to operate a camera or to quickly find and operate a remote controller.

However, in the present invention, when it is estimated that a traffic accident is required without any other operation by the driver (when the brake is pressed as quickly as possible), the photographing is automatically performed.

On the other hand, the present invention can be taken manually according to the needs of the driver.

That is, when the driver operates the manual shooting switch SW4 in the manual shooting operation unit 160 in the on state, the controller 130 recognizes this and operates the shutter driver 140 to automatically press the shutter to shoot. .

On the other hand, when photographing is finished or the film is used up, a specific signal is applied to the controller 130 although not shown in the drawing. For example, a specific signal may be applied to the controller 130 by sensing the last portion of the film.

The control unit 130 applies a motor driving signal to the film collecting unit 150 when a specific signal is applied, and the film collecting unit 150 inverts the phase of the motor driving signal in the inverter 151 and the inverter. The transistor Q2 operates in a turn-on state by the output of 151 to supply driving power to the motor 152, so that the motor 152 operates to automatically wind the film.

According to the above-described "car imaging apparatus for cars" according to the present invention, the camera is installed to take an image in the car, the advantage of being able to automatically photograph the surroundings of the car when the brake is operated as much as possible in a traffic accident or emergency have.

In addition, since the automatic shooting as described above can determine the accuracy of the cause of the traffic accident in the future, there is also an advantage that can overcome the disadvantage that the good may be disadvantaged by insufficient evidence.
