2. Description of the Related Art Conventionally, surveillance cameras have been installed in a plurality of surveillance areas, and surveillance images taken by each surveillance camera are transmitted to a surveillance center through a transmission line. 2. Description of the Related Art There is known a monitoring system that displays a monitor to monitor crimes and accidents.

Further, in the above-mentioned monitoring system, an emergency call transmitted from a person who witnesses a crime, accident or the like using a portable terminal or other terminal is accepted at a predetermined monitoring center, and the location of the sender of the emergency call is determined, for example. It is identified by GPS, wireless, etc., and the surveillance cameras in the vicinity are activated, and the guards are dispatched.

[0004] Recently, a crime prevention tower equipped with a radio for emergency call is installed in a downtown area, and when a crime occurs, when a report button provided on the crime prevention tower is pressed, a predetermined transmission line is used. A system has been considered in which a predetermined monitoring center or police is notified.

[0005]

However, in the above-mentioned conventional monitoring system, an emergency call from a mobile terminal to a predetermined monitoring center is connected by a public line and after the position of the mobile terminal is specified by GPS or the like, An operation signal is transmitted from the monitoring center to a predetermined monitoring camera, and the monitoring camera starts the monitoring operation, which causes a time delay. Also,
If the GPS radio wave does not reach the mobile terminal, the position of the mobile terminal cannot be specified and the surveillance camera cannot be operated.

When making an emergency call from the crime prevention tower, it is possible to report directly to the police, but the caller must move to the crime prevention tower and press the report button.
There is a problem that the call to the police is delayed.

The present invention has been made to solve the above problems, and a monitoring device can immediately start a monitoring operation by an emergency call from a mobile terminal and send an emergency call and a monitoring image to a monitoring center. It is an object of the present invention to provide a monitoring device and a monitoring system that are highly urgent and are not affected by the availability of GPS radio waves.

[0008]

According to the present invention, there is provided an emergency call function in a surveillance device which comprises a rotating surveillance camera for photographing a surveillance area and which transmits a surveillance image photographed by the surveillance camera to a surveillance center through a transmission line. When an emergency call is received from the mobile terminal, the emergency call is transmitted to the monitoring center via the transmission line and the mobile phone A small radio area small base station device that detects the direction of arrival of radio waves from a terminal, and a shooting operation by rotating the swivel-type surveillance camera in the direction of arrival of radio waves from the mobile terminal detected by the small radio area small base station device. Control means for starting and transmitting the surveillance image photographed by the rotating surveillance camera to the surveillance center via the transmission line. It is characterized in.

According to the above configuration, when the monitoring device receives an emergency call from the mobile terminal, the direction of the received radio wave, that is, the direction of the mobile terminal is detected by the small radio area small base station device equipped with the adaptive array antenna. Then, turn the turning surveillance camera in the direction in which the mobile terminal is located,
Images of crimes and accidents are taken and transmitted to the monitoring center.
Therefore, the monitoring center can check the situation such as a crime or accident that has occurred from the caller and take immediate action.

When the monitoring device 3 located at a distance communicable with the portable terminal 7 receives the radio wave transmitted from the portable terminal 7 by the small radio area small base station device 11, first, whether the received signal is an emergency call or not. Is confirmed by the presence or absence of an emergency call code. If it is not an emergency call, it is determined that the call is a normal call and no reception processing is performed.

Upon confirming that the received signal from the mobile terminal 7 is an emergency call, the miniature wireless area small base station apparatus 11 transmits the emergency call to the monitoring center 1 together with the ID number, and at the same time, the mobile terminal 7 and the monitoring center. The relay operation is performed so that the call can be made to and from 1.

Further, a very small radio area small base station device 11
When receiving an emergency call from the mobile terminal 7, detects the radio wave arrival direction from the radio wave reception intensity of each antenna element 6a to 6n of the adaptive array antenna 6, and instructs the control unit 12 about the radio wave arrival direction. The control unit 12 directs the monitoring direction of the swing type monitoring camera 13 toward the mobile terminal 7 and starts a photographing operation in accordance with a control command from the minimum radio area small size base station device 11.

The rotating surveillance camera 13 starts its operation in response to a control command from the control unit 12, photographs the situation in the direction in which the portable terminal 7 is located, and takes the photographed image as a very small radio area small base station apparatus 11. From the transmission line 2 to the monitoring center 1.

On the other hand, in the monitoring center 1, when an emergency call is sent from the monitoring device 3, the person in charge of the call talks with the caller via the mobile terminal 7, and the content of the call, that is, the crime or accident that occurred is reported. The situation is confirmed, an emergency call is sent to the public institution 5, and the monitoring image sent from the monitoring device 3 is transferred. The public institution 5 deals with crimes and accidents that have occurred based on the emergency call from the monitoring center 1, the monitoring image and the like.

Further, the monitoring center 1 confirms the monitoring image sent from the monitoring device 3 by the swivel monitoring camera 13, and if the swivel monitoring camera 13 is out of the monitoring direction, it sends the camera control information. It is sent to adjust the monitoring direction and the like of the swing-type monitoring camera 13. That is, it is possible to correct the monitoring direction of the swivel-type monitoring camera 13 when a deviation occurs, such as when the direction detection by the adaptive array antenna 6 does not reach.

According to the above embodiment, when the monitoring device 3 receives the emergency call from the mobile terminal 7, the monitoring device 3 transmits the emergency call to the monitoring center 1 and at the same time, the small radio area small base station equipped with the adaptive array antenna 6 is installed. Since the device 11 detects the direction of the mobile terminal 7 and directs the turning surveillance camera 13 in that direction to start the photographing operation,
At the same time as receiving an emergency call from the mobile terminal 7, the turning surveillance camera 13 can be turned toward the mobile terminal 7 to photograph a situation such as a crime or an accident and transmit it to the monitoring center 1. Therefore, in the monitoring center 1, it is possible to confirm the situation such as a crime or accident that has occurred from the whistleblower and take immediate action. Can quickly deal with crimes and accidents.

Further, the monitoring operation can be immediately started by the monitoring device 3 which has received the emergency notification from the portable terminal 7 regardless of the availability of GPS radio waves, and a monitoring device and a monitoring system excellent in urgency are constructed. be able to.
