In other embodiments, the storage module 22 may be a combination of a plurality of the foregoing storage media, such as a disk array.

In one embodiment, the storage module 22 can be built into the image monitoring device 20. The present invention is not limited thereto. In some embodiments, the storage module 22 can also be connected to the image monitoring device 20 through a connection interface. . The connection interface may be a Parallel Advanced Technology Attachment (PATA) standard, an Institute of Electrical and Electronic Engineers (IEEE) 1394 standard, and a Peripheral Component Interconnect Express (PCI). Express) standard, Universal Serial Bus (USB) standard, Secure Digital (SD) interface standard, Ultra High Speed-I (UHS-I) interface standard, ultra-high-speed second generation ( Ultra High Speed-II, UHS-II) interface standard, Memory Stick (MS) interface standard, Multi Media Card (MMC) interface standard, Embedded Multimedia Card (eMMC) Interface standard, Universal Flash Storage (UFS) interface standard, Compact Flash (CF) interface standard, Integrated Device Electronics (IDE) standard or other suitable standards, The invention is not limited by this.

The first communication module 23 communicates with the central control servo device 10 in the first communication protocol, and transmits the monitoring image to the central control servo device 10 instantaneously or selectively. In other words, the first communication module 23 can acquire the monitoring image and transmit the monitoring image to the central control servo device 10 in accordance with the first communication protocol. In an embodiment, the first communication protocol may be wired communication, such as: Ethernet, power line network, universal serial bus (USB), RS232, and the like. In another embodiment, the first communication protocol may also be wireless communication, such as: GSM, GPRS, EDGE, UMTS, W-CDMA, TD-CDMA, Bluetooth, NFC, WiFi, WiMAX, LTE, LTE-A or TD-LTE and so on. However, the above-mentioned communication protocol is merely illustrative, and the present invention is not limited to the above communication method.

Here, the second communication protocol may be GSM, GPRS, EDGE, UMTS, W-CDMA, TD-CDMA, Bluetooth, NFC, WiFi, WiMAX, LTE, LTE-A or TD-LTE, etc., and the present invention is not limit. However, the above-mentioned communication protocol is merely illustrative, and the present invention is not limited to the above communication method.

The abnormality detecting module 25 can cause the second communication module 24 to transmit the monitoring image stored by the storage module 22 to the second image monitoring device 202 to back up the monitoring image. Thereby, the monitoring image of the first image monitoring device 201 can be backed up by the storage module 22 in the second image monitoring device 202. The following describes what is an abnormal state of the device, which means that the component to which the image monitoring device 20 belongs or the operation of the component and the outside is abnormal. In some embodiments, the abnormal state of the storage module 22 refers to an abnormality in the storage module 22, for example, an abnormal situation such as insufficient storage space of the storage module 22 and an access error. For example, when the abnormality detecting module 25 of the first image monitoring device 201 detects that the connected storage module 22 is abnormal, the first image monitoring device 201 is transmitted via the second communication module 24. The real-time monitoring image is sent to the second image monitoring device 202 for the second image monitoring device 202 to store the monitoring image of the first image monitoring device 201 during the communication abnormality in the storage module 22 for backup. If the storage space is insufficient, the first image monitoring device 201 can delete the monitoring image originally stored in the storage module 22 after the monitoring image is transmitted, thereby clearing more storage space for storing the new monitoring image. .

In another embodiment, the abnormal state of the self refers to an abnormality of the first communication module 23 or an abnormal communication between the first communication module 23 and the central control servo device 10 (eg, the network route is removed, the hub is faulty, etc.) The reason is that the abnormal situation causes the data to be smoothly transmitted between the first communication module 23 and the central control servo device 10. Therefore, when the abnormality detecting module 25 of the first image monitoring device 201 detects the communication abnormality, the second monitoring module 24 can transmit the real-time monitoring image of the first image monitoring device 201 to the second image monitoring device. The second image monitoring device 202 stores the received monitoring image in the storage module 22, so that the first image monitoring device 201 can back up the monitoring image during the communication abnormality to the second image monitoring device 202. Or further transmitted to the central control servo 10 via the second image monitoring device 202 for monitoring or backup.

In some embodiments, the self-abnormal state refers to an abnormality of the image capturing module 21. In an embodiment, the anomaly detection module 25 can also perform image recognition on the surveillance image captured by the image capture module 21 to detect whether the image capture module 21 has an abnormal state. If an abnormal state occurs, it is determined that it is abnormal. For example, the shooting range of the image capturing module 21 is changed (for example, being turned and covered). If the image capturing module 21 detects that the abnormality occurs, the monitoring image of the image capturing module 21 can be further transmitted to another image monitoring device 20 for backup.

Referring to FIG. 2, FIG. 2 is a schematic structural diagram of a conditional backup image monitoring system according to a second embodiment of the present invention. The difference from the first embodiment is that the image monitoring device 20 of the embodiment further includes a light sensor 211 and a motion sensor 212, which are disposed on the image capturing module 21, so that the sensor can be detected by the sensor. Whether the image capturing module 21 is abnormal or not is detected by the image recognition method to detect whether the image capturing module 21 is abnormal. The light sensor 211 and the motion sensor 212 are respectively connected to the abnormality detecting module 25. The abnormality detecting module 25 can determine whether the image capturing module 21 is covered by the light receiving signal detected by the light sensor 211. Through the motion data detected by the motion sensor 212, the abnormality detecting module 25 can determine whether the image capturing module 21 has an abnormal event such as up-and-down swing or left-right deflection. When the image capturing module 21 generates an abnormal event such as up-and-down swinging or left-right deflection, the abnormality detecting module 25 can transmit the monitoring image of the predetermined time before and after the abnormal event occurrence time to the second image via the second communication module 24. The monitoring device 202 can back up the key images at the time of the incident. The light sensor 211 can also be a photo interrupter, an infrared ray interrupter, a laser light occlusion device, or other light sensing device, and the invention is not limited thereto. The motion sensor 212 can be a gyroscope, an acceleration sensor, or other sensor that senses an angle change, and the invention is not limited thereto.

According to the monitoring system of the conditional backup image of the foregoing embodiment, the image monitoring device 20 passively receives the monitoring image to be backed up by the other image monitoring device 20, so that the image monitoring device as the backup terminal can back up the monitoring image of each image monitoring device 20. In order to avoid the problem of loss of its own monitoring image due to an abnormality in one of the image monitoring devices 20.

3 is a schematic diagram of active backup of a conditional backup image monitoring system according to a first embodiment of the present invention. In order to protect the surveillance image more comprehensively, the first embodiment of the present invention also provides an active backup mode for an image monitoring device 20 to actively request other image monitoring devices 20 to transmit the stored monitoring images for backup. Referring to FIG. 3 , the first image monitoring device 201 is photographed toward the second image monitoring device 202 , that is, the second image monitoring device 202 is within the shooting range of the first image monitoring device 201 . Therefore, the second image monitoring device 202 is included in the monitoring image captured by the first image monitoring device. Through the image analysis method, the abnormality detecting module 25 of the first image monitoring device 201 can detect whether the monitoring image is abnormal. If it is determined that the monitoring image is abnormal, the first image monitoring device 201 can send a backup command to the second image monitoring device 202 in the monitoring image via the point-to-point transmission link (ie, the second image monitoring device 202 that has an abnormality). The second image monitoring device 202 thus responds to the backup command to transmit the stored monitoring image to the first image monitoring device 201 via the point-to-point transmission link for the first image monitoring device 201 to perform backup.

Here, the abnormality may be an intrusion abnormality or an abnormality of the second image monitoring device 202. Intrusion anomalies refer to signs of intrusion within the shooting range, such as the presence of shadows or smoke in the alert area. The second image monitoring device 202 may be abnormal, for example, that the second image monitoring device 202 is changed in the set position or changes the shooting angle. However, the above abnormal state is merely an example, and the embodiment of the present invention is not limited thereto. In addition to the passive backup, the active backup can make the monitoring level more comprehensive. For example, if the second image monitoring device 202 does not detect abnormal conditions, the first image monitoring device 201 can still detect the second image monitoring. The device is abnormal, and the second image monitoring device can be requested to back up the stored monitoring images.

4 is a schematic structural diagram of a conditional backup image monitoring system according to a third embodiment of the present invention. Referring to FIG. 4, the first communication module 23 of the image monitoring device 20 may further include an instruction receiving module 231 connected between the abnormality detecting module 25 and the security host 30. The command receiving module 231 in the first image monitoring device 201 receives the alarm information from the security host 30. Here, the security host 30 is connected to the security sensor, and the alarm information can be output according to the detection result of the security sensor. When detecting the alarm information, the abnormality detecting module 25 can cause the second communication module 24 to transmit the stored monitoring image to the storage module 22 of the second image monitoring device 202 to back up the monitoring image. Similarly, the second image monitoring device 202 can also transmit its own monitoring image to the first image monitoring device 201 in response to the alarm information of the security host 30 to back up the monitoring image, thereby transmitting the monitoring image to another image. By monitoring the device 20, the surveillance image can be preserved more comprehensively. The command receiving module 231 is not limited to being located in the first communication module. In an embodiment, the command receiving module 231 can also be connected to the security independently of the first communication module 23 (not shown). Between the host 30 and the anomaly detection module 25.

Here, although FIG. 4 illustrates two security hosts 30 that are respectively connected to the first image monitoring device 201 and the first communication module 23 of the second image monitoring device 202, embodiments of the present invention are not limited thereto. The first image monitoring device 201 and the second image monitoring device 202 can also be connected to the same security host 30.

As can be seen from the above, the image monitoring device 20 of the embodiment of the present invention can store the monitoring image captured by itself, and can also store the monitoring image backup of the other image monitoring device 20. Therefore, in some embodiments, the abnormality detecting module 25 of the image monitoring device 20 can combine the monitoring images associated with the same image time point into an integrated image, and store the integrated image in the storage module 22, that is, the storage module. When each of the monitored images stored in group 22 is associated with the same image time point, they can be combined into an integrated image. The image time point is a similar time point in each of the monitoring images in each image monitoring device 20. The similar time of the image means that the time difference can be within 1 minute, within 5 minutes or other time, and the visual demand can be adjusted. Taking the first embodiment as an example, the image time of the first image monitoring device 201 is 12 noon, and the image time of the second image monitoring device 202 may be 11:59 to 12:01. The integrated image may be a multi-segmented window, and the monitoring images captured by the plurality of image monitoring devices 20 are simultaneously displayed in a single screen.

FIG. 5 is a schematic structural diagram of a conditional backup image monitoring system according to a fourth embodiment of the present invention. Referring to FIG. 5, the difference between the embodiment and the foregoing first to third embodiments is that the number of the image monitoring devices 20 of the embodiment may exceed two, and the five image monitoring devices 20 are taken as an example. The second communication module 24 in the monitoring device 20 can form the aforementioned point-to-point transmission link with the other one or more second communication modules 24 to form a mesh network topology. That is, the first image monitoring device 201 shown in FIG. 1 can be connected to the communication module 24 of the image monitoring device 20 in the communication range of the second communication protocol. Similarly, the second image monitoring device 202 shown in FIG. 1 can also be connected to the communication module 24 of the image monitoring device 20 in the communication range of the second communication protocol.

In one embodiment, the second communication module 24 selects one of the image monitoring devices 20 in the communication range of the second communication module 24 to establish a point-to-point transmission link according to a priority connection sequence. The priority connection order is the connection order of the first image monitoring device 201 and each image monitoring device 20. For example, the first image monitoring device 201 shown in FIG. 1 can store a preset priority connection sequence, which is to set the first image monitoring device 201 to first connect with the second image monitoring device 202, for any reason. When the second image monitoring device 202 cannot be connected, the first image monitoring device 201 is changed to the third image monitoring device connected to the next priority order (ie, the second priority) (not shown), and so on. Furthermore, the first image monitoring device 201 may first poll (Polling) whether the second image monitoring device 202 can be connected according to the priority connection order, and if not, then query the third image monitoring device of the second priority order, according to which analogy.

In another embodiment, the priority connection order of each image monitoring device 20 may not be preset, but based on the instantaneous signal strength. That is, if the signal strength between the first image monitoring device 201 and the second image monitoring device 202 is the strongest, the priority connection sequence is set such that the first image monitoring device 201 and the second image monitoring device 202 are connected. Similarly, if the first image monitoring device 201 and the third image monitoring device have the strongest signal strength, the first image monitoring device 201 preferentially forms a connection with the third image monitoring device.

In some embodiments, as described above, a plurality of image monitoring devices 20 may form a mesh network. When one of the image monitoring devices 20 detects that the storage module 22 has insufficient space, it may The surveillance image backup of the surveillance image or other image monitoring device 20 is transmitted to another one or more image monitoring devices 20 for storage.

According to the above embodiment, the monitoring system provided by the present invention can back up the monitoring image in a passive manner or in an active manner, thereby maintaining the monitoring image in detail, and avoiding the loss of the monitoring image caused by the operation or destruction of the thief or the unspeakable person who is familiar with the monitoring device. It can also enable the monitoring personnel at the end of the central control servo device 10 to immediately know the situation of the abnormal situation, so as to be able to make correct response, such as dispatching appropriate security personnel, alarming, reporting fire fighting units or the like, etc. Avoid losing the golden age of the scene due to the loss of surveillance images.
