I. Field of the Invention
This invention relates generally to a display switcher and, more specifically, to a display switcher with mobile communication interface that transmits the image signals captured by cameras to a remote site mobile phone and display on the screen of the remote site mobile phone as a remote monitoring function for safety purpose.
II. Description of the Prior Art
Heretofore, it is known that display switches are applied on the security systems of buildings or offices, the areas of buildings and offices are general very large to have guards or security personnel watch everywhere, therefore cameras are used to monitor, the display switches can watch a plurality cameras to a monitor, the display switch can switch various frames with definite time period; the monitors are installed on some stationary location, when guards go to check some abnormal situation, they cannot watch the monitors at the same time.
The monitor systems need people to watch all the time, general residential environments are not suitable to install such monitor system; burglar intrusion or abnormal situation often happen when all the family members are out for work or travel, such as fire, such situation is aware only when it is very serious or when people return home, the situation is very dangerous if burglar is still inside the house; children are often left at home when young parents have to go out or work, young children might cause danger while playing, such as fire; elderly people having health problems might have emergency condition and need treatment.
It is therefore a primary object of the invention to provide a display switcher with mobile communication interface that transmits the image signals captured by cameras to a remote site mobile phone and display on the screen of the remote site mobile phone as a remote monitoring function for safety purpose.
In order to achieve the objective set forth, a display switcher with mobile communication interface in accordance with the present invention comprises a switching circuitry, an image processor, a central processor, a memory unit and a mobile communication interface; the central processor transmits control signals to the switching circuitry based on internal program to have the switching circuitry switch the images automatically and capture images from different cameras, the images are converted into digital signals and edited, stored into said memory unit, the central processor compares the current image signals of every camera with last image stored in the memory unit for difference, the mobile communication interface transmits signals in mobile phone protocol through a mobile phone, the remote site mobile phone receives and displays the image signal on screen for remote monitoring function for safety purpose.
The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
Referring to
The switching circuitry 2 of the display switcher with mobile communication interface 1 connects to a plurality of cameras 7 with image paths; the switching circuitry 2 switches the image paths in order or switches to the selected image path by the program or instruction of the central processor 4, the image signals captured by the cameras 7 can also be switched in order in a definite time period; when the switching circuitry 2 switches to one of the cameras 7, the image signals captured by that camera 7 are sent to the image processor 3. The image signals captured by the camera 7 are analog signals, the analog signals are converted into digital signals by the image processor 3, and those digital signals are transmitted to the central processor 4. The mobile communication interface 6 connects to the mobile phone 9 and applies the mobile phone 9 to receive and transmit mobile wireless digital signals. The central processor 4 stores image signals into the memory unit 5 and controls different functions of the display switcher with mobile communication interface 1 based on internal program or external commands.
Based on above description, when all the family members are out, the display switcher with mobile communication interface 1 is set to automatic alarm mode, the central processor 4 transmits control signals to the switching circuitry 2 automatically based on internal program to have the switching circuitry 2 switch the images automatically and capture images from different cameras 7, the images are converted into digital signals and edited, stored into the memory unit 5 by the central processor 4. The central processor 4 compares the current image signals of every camera 7 with last image stored in the memory unit 5 for difference, if difference happens, the central processor 4 determines the abnormal condition might occur (burglar intrusion or fire alert), the central processor 4 transmits the warning messages and that image signals to the mobile communication interface 6, the mobile communication interface 6 transmits the warning messages and the image signals in mobile phone protocol through the mobile phone 9, the warning messages and the image signals go through macrocell and mobile phone switchboard, then the macrocell transmits the warning message and the image signals to the designated mobile phone 8. Based on above description, users can see the warning message and the image signals through the designated mobile phone 8; users can call police or fire department for assistance to reduce loss.
The display switcher with mobile communication interface 1 not only has the image signals comparison capability as monitor function but also can connect to the anti-theft sensors or doorbells to collect the signals from the anti-theft sensors or doorbells, if abnormal signals are detected or the doorbells are pressed, the warning messages and image signals are transmitted to the designated mobile phone 8, users can call police or fire department for assistance or see who presses the doorbell for emergency assistance, users can rush back at the same time.
When elderly people or young children are alone at home, the display switcher with mobile communication interface 1 can be set on monitoring mode; users can call the designated number to view the image signals, the mobile communication interface 6 receives the commands from macrocell and mobile phone switchboard from the mobile phone 9 and transmits the commands to the central processor 4, the central processor 4 passes the captured image signals of a designated or a plurality of cameras 7 to the designated mobile phone 8 through the mobile communication interface 6, and displays the image signals of the designated or a plurality of cameras 7 in sequence; users can view the physical condition of elderly people or the situation of the young children as safety precaution.
The mobile communication interface 6 includes a wireless receiving/transmission module of the mobile phone 9 to have the display switcher with mobile communication interface 1 transmit and receive wireless signals without connecting to a mobile phone 9.
While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
