In the conventional surveillance camera system described above, since the surveillance camera is connected via a cable, if an intruder or the like cuts the cable, an image cannot be obtained, and an abnormality such as a cable cut is immediately caused. There was a problem that it could not be detected.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a surveillance camera system that can prevent failure due to disconnection or the like and can quickly detect the occurrence of an abnormality.

In order to achieve the above object, the invention according to claim 1 is a surveillance camera system using a simple mobile phone system in which a service control station and a radiotelephone terminal constantly respond with a control signal via a radio base station. The wireless telephone terminal can set a monitoring camera, a sensor for detecting an intruder, a normal telephone mode used as a normal telephone, and a monitoring camera mode for transferring image data from the same monitoring camera. And a mobile phone that enters the surveillance camera mode when the surveillance camera is connected, and the service control station includes terminal calling means for calling the mobile phone via the wireless base station, and the non-response processing means for performing a predetermined non-response processing when the mobile phone was unanswered calls in means, when the mobile telephone responds When the image data is received from the mobile phone and the intruder is not detected by the sensor, the received image data is collectively transferred to a transfer destination every predetermined time, and the intruder is detected by the sensor. In some cases, the apparatus includes a response processing unit that transfers image data to the transfer destination each time image data is received from the mobile phone .
[Action]
In the invention according to claim 1 configured as described above, the mobile phone can set a normal telephone mode used as a normal telephone and a monitoring camera mode in which image data is captured from the monitoring camera and transferred. When the surveillance camera is connected, the surveillance camera mode is automatically set. The terminal calling means of the service control station calls the mobile phone via a radio base station, non-response processing unit when the mobile phone was unanswered performs a predetermined process such as an emergency contact. On the other hand, the mobile phone transfers captures image data from the monitoring camera in accordance with the setting if the cellular phone them respond. The response processing means of the service control station receives the image data from the mobile phone when the mobile phone responds. If the sensor does not detect the intruder, the received image data is batched every predetermined time. When it is transferred to the transfer destination and an intruder is detected by the sensor, it is transferred to the transfer destination every time image data is received from the mobile phone .

Here, the call of the wireless telephone terminal can be performed as a call of a general call, or may be only a response of a control signal using the control channel. If the call is made in response to a control signal, a call channel is not required. Also,
When there is a response, whether or not to transmit / receive image data may be determined only by confirming that image data can be transmitted according to the setting.

As described above, according to the present invention, since a mobile phone is called and monitored depending on whether or not there is a response, the mobile phone is not responding while preventing a failure due to cable disconnection as in the case of wired communication. It is possible to immediately determine that there is an abnormality, and when a surveillance camera is connected, the mobile phone automatically enters the surveillance camera mode, and when the mobile phone responds, the service control station When the image data is received from the telephone and the intruder is not detected by the sensor, the received image data is transferred to the transfer destination at once every predetermined time, and when the intruder is detected by the sensor, the mobile phone It is possible to provide a surveillance camera system that transfers image data to the transfer destination every time it receives image data from a telephone .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a radiotelephone terminal according to an embodiment of the present invention, and FIG. 2 is a schematic view showing the entire system.

In the figure, a radio telephone terminal 10 performs radio transmission / reception with radio base stations 20 arranged in a scattered manner, and the radio base station 20 is connected to a service control station 4 via a commercial digital communication network 30.
Connected to 0. The service control station 40 is connected to the security company 50 and the client 60 via the commercial digital communication network 30 and the like. In this embodiment, security company 5
0 and the client 60 are assumed to be fixed telephone terminals connected to the commercial digital communication network 30. However, it is sufficient that they can communicate with each other in some form, and may be a radio telephone terminal 70, or digital network / analog network switching. Analog line fixed telephone terminals connected via the device 80, etc.
Any device capable of communicating with the wireless telephone terminal 10 may be used.

The wireless telephone terminal 10 includes a mobile phone 11 and a camera unit 12 connected to the mobile phone 11 in order to receive an instruction at the time of an incoming call and transfer image data from the monitoring camera.
The mobile phone 11 is a digital radio telephone that employs a TDMA / TDD system called PHS, has a transmission capacity of 32 kilobits / second, and is used for updating location information with the service control station 40. Control signals are constantly transmitted and received. Camera unit 12 is CC
A D imaging device is provided, and is connected to the digital input terminal of the mobile phone 11. The mobile phone 11 and the camera unit 12 are installed in a place where monitoring is necessary.

In the present embodiment, the mobile phone 11 and the camera unit 12 are configured as separate units so that existing hardware can be used easily, but an integrated videophone type can also be used. In addition, it is possible to provide a bracket so that it can be easily installed at a monitoring place. Further, the lens may be fixed or replaceable. In this case, a wide angle can be set so that a wide range can be shot, or a telephoto range can be set so that a predetermined portion can be shot up. Further, zoom, tilt, and pan functions may be provided.

For long-term monitoring, the built-in battery can be charged sequentially by connecting to a commercial power source. Further, in a place where it is difficult to wire the commercial power supply, it is possible to connect the solar cell panel 13 as shown in FIG. 3 and charge it during the daytime. Although it is preferable to have a charging function, it is not always necessary when it is assumed that the battery is operated only in a bright state.

This mobile phone 11 performs terminal-side control by software corresponding to the flowcharts shown in FIGS. First, the use mode of the mobile phone 11 can be set, the mode setting is selected within a predetermined function setting, and as shown in FIG. 4, it is used as a normal phone or used as a monitoring camera in step 110. Select. In the normal telephone mode, normal incoming and outgoing calls are performed, and in the surveillance camera mode, standby processing and image transmission processing shown in FIGS. 5 and 6 are executed. That is, in the standby process, the presence / absence of an incoming call is constantly monitored in step 120. If there is an incoming call, image data is requested as a response process in step 121 or a system check is simply requested. If image data is requested, the process branches to a subroutine for image transmission at step 122. Regarding the response processing, it is important to transfer the monitoring image itself, but whether or not the response can be made is also an important factor, and an image data request is previously provided as a check option in the data setting step 218 on the service control station 40 side. Or system check is selected.

In the branched image transmission process, the monitoring image is captured by the camera unit 12 in step 130, and the image data is transmitted from the mobile phone 11 in step 132. When the transmission of the image data is finished, the image transmission process is terminated and the process returns to the standby process. In step 124, the line is disconnected by being on-hooked, and then the process returns to the incoming call standby state in step 120. On the other hand, if it is a system check request, in step 126, a system check is performed to determine whether or not the mobile phone 11 is operating normally, and the system check data is transmitted.

In this embodiment, the user sets the mode of the mobile phone 11.
For example, when the camera unit 12 is connected, it can be controlled to automatically enter the surveillance camera mode. In addition, when shooting an image, it is possible not to shoot only at the time of an incoming call, but also to shoot at regular intervals and send them together at the time of the incoming call. Furthermore, a sensor for detecting an intruder can be arranged, and when the sensor is activated, a plurality of images can be taken and transmitted by shortening the photographing interval. Further, the selection of image data request or system check may be set on the radio telephone terminal 10 side.

On the other hand, in the service control station 40, data setting processing and monitoring processing corresponding to the flowcharts shown in FIGS. 7 and 8 are performed. The wireless telephone terminal 10 is called and the called wireless telephone terminal 10 is not responding. If there is an emergency contact, when the wireless telephone terminal 10 responds, a predetermined process of receiving system check data or receiving and transferring or saving image data to be transferred is executed.

In order to call the radio telephone terminal 10, it is necessary to set data in advance.
In the data setting, in addition to the check option in step 218 described above, the telephone number of the camera terminal that is the wireless telephone terminal 10 called in step 210 is set, and the emergency contact address in the case of no response is set in step 212. In step 214, the transfer destination of the image data is set. The radio telephone terminal to be called, the emergency contact address, and the forwarding telephone number are basically essential, but the emergency contact address and the forwarding address may be the same.

In step 216, an option for transferring the image data is set. In the present embodiment, for example, a sequential transfer option for transferring image data every time it is received;
A batch transfer option for batch transfer at a predetermined time can be selected. As for the transfer method, these may be further combined, and as described above, when an intruder is detected by the sensor on the side of the radio telephone terminal 10, it is possible to change the transfer method as appropriate.

In the state where the telephone number of the wireless telephone terminal to be called is set as described above, the service control station 40 selects the telephone number of the camera terminal at step 220 and makes a call at step 222. When selecting the phone number of the camera terminal, the phone numbers may be selected in the order as listed or randomly. It is also possible to set the necessary frequency and change the selection frequency. As for a call to the radio telephone terminal 10, a call is made like a normal call. However, when only the system check request is made with the check option, even if the call channel is not used, a call is made only on the control channel using the control signal that is constantly transmitted and received, and the system is used. A check may be requested.

In the case of a normal wireless or wireless telephone system, the number of channels that can be used for communication is determined. Therefore, if all the communication channels are used at a certain time, it is impossible to make a call even if the intention to make a call is a system check. If such a situation occurs, the reliability of the monitoring system will be reduced. However, in the case of a simple mobile phone system, the control channel can always be used even if all the call channels are used. For this reason, the system check can always be performed at the same frequency, and the reliability of the system can be improved.

When a call is made, the process differs depending on whether the wireless telephone terminal 10 has made a response or not. Whether or not a response has been made is determined in step 224 based on whether or not a response has been received, and in step 226 whether or not a specified time has elapsed since the call was started. Since the wireless telephone terminal 10 waits for an incoming call and waits to transfer image data as described above, the incoming call is received within a predetermined time if the system is normal. Therefore, if there is no incoming call within the designated time after receiving the call, there may be a failure or an intruder has broken the surveillance camera, and the emergency contact is automatically notified at step 228. The emergency contact information is recorded in the data setting process, but is the security company 50 or the requester 60. The contact information may be changed according to the time of day, or both may be called, or the police may be contacted. Such processing corresponds to non-response processing.

On the other hand, if a response is made, it is determined in step 229 whether an image data request is to be made or a system check request is to be made, and a command command corresponding to each is sent to the radiotelephone terminal 10.
Send to. In this case, the service control station side transmits a command command. However, as described above, when the service control station 40 performs a call process, the mobile phone 11 is set on the mobile phone 11 side. Step 229 is performed by determining data automatically transmitted from the side.
The branch process may be performed at.

When requesting image data, the image data captured by the camera unit 12 is transmitted from the wireless telephone terminal 10, and the processing of this image data is determined. That is, it is determined whether the sequential transfer option or the batch transfer option is selected in the data setting.

If the batch transfer option is set, it is received and stored in step 232 for the time being. In step 234, it is determined whether or not it is a batch transfer timing. For example, when transferring every five times, it is determined that the transfer timing is not from the first time to the fourth time, and this monitoring process is terminated. However, if it is the fifth time, the transfer destination is called in step 236. This transfer destination is set by the data setting described above. If the connection can be made in response within a predetermined time (step 238), the data is transferred in step 240. If the response cannot be made within the predetermined time (step 238), the error image is stored in step 242. Various methods are conceivable for processing the stored error image. However, hard copy may be used and transferred by another means such as a fax, or the operator may be prompted to contact by another means. In this case, you may make it contact an emergency contact address. In this embodiment, the image data is transferred every fifth time. However, the image data may be compared, and if there is a change, the image data may be transferred regardless of whether it is the transfer timing. In addition, since it is normal for the amount of communication to decrease at night, image data may be sent frequently at night. This is extremely advantageous due to the great demand for nighttime monitoring.

If the sequential transfer option is set, perform the same processing as step 236 and subsequent steps.
Call the transfer destination each time and transfer the received image without saving it. Whether or not to save the received image can be changed as appropriate according to the situation of the system. The image data may be received and stored, and the stored data may be transferred. In this case, for example, the image data for the past five times can be stored in the service control station 40.

On the other hand, in the case of a system check, it is not determined that the system is normal only by the response, but it is determined in step 246 whether the system check data is received and whether it is normal. If it is normal, the monitoring process may be terminated. However, if it is determined that the camera is not normal, for example, if there is an abnormality in the camera, the process branches to step 228 just in case and the above-described emergency contact is performed. Do.

The above processing corresponds to the response processing, but is not necessarily limited to the above-described processing, and at least the wireless telephone terminal 10 that has responded may be processed by some method. For example, although the above-described embodiment is based on transferring image data, the original image may be restored from the received image data, and the presence or absence of an abnormality may be determined by viewing the image. In this case, an emergency process such as calling the camera terminal on the security company's side and checking the image when responding, or urgently going to the site if not responding, is not performed by the wireless telephone service control station. That's fine.

As described above, the wireless telephone terminal 10 including the camera unit 12 and the mobile phone 11 performs standby processing such as performing system check after waiting for an incoming call or transferring image data obtained by capturing an image. In the service control station 40 having 20, the set radio telephone terminal 10 is called, and if it does not respond, emergency processing such as emergency contact or rushing to the site is executed as a system abnormality. If the monitoring process such as checking the check data, transferring the image data, or monitoring is executed, the cable is not cut and cannot be monitored as in the case of the cable, and the monitoring cannot be performed. Can't answer the next call, so it can be detected reliably.

Since the service control station's main business is communication services, the service control station only performs system checks, and image data processing can be performed by a security company or client using a call channel. The change of can also be made very small.

Further, in the above-described embodiment, the call processing is performed from the service control station 40 side, but any service may be used as long as the service control station 40 and the radiotelephone terminal 10 regularly respond with a control signal. Therefore, it is also possible to perform call processing from the radio telephone terminal 10 side. The timing for performing the call processing may be regular, may be an abnormality such as detection of an intruder, or a combination thereof. Of course, in this case as well, a control signal response may be performed using the control channel. At this time, system check data including detection data may be transmitted. On the other hand, on the service control station 40 side, not only the monitoring of the radio telephone terminal 10 but particularly the response of the normal control signal is executed and the radio telephone terminal 10 having such a monitoring camera is used. The above-described processing may be started when a control signal response is received.
