1. Technical Field
The present disclosure relates to electronic devices and methods thereof, and security monitoring systems and, particularly, to an electronic device and method for immediately transmitting warning information, and security monitoring system.
2. Description of Related Art
The conventional security monitoring systems usually include video cameras to allow people to observe the monitored items. It is necessary for the security monitoring systems to provide a warning when the monitored items have moved out of a predetermined area.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
Embodiments of the present disclosure are now described in detail, with reference to the accompanying drawings.
Referring to
The electronic device 10 includes a radio frequency receiving unit 11, a detector 12, a storage unit 13, a camera 14, a wireless transmitting unit 15, and a processor 16. The monitoring device 20 includes a radio frequency transmitting unit 21, a wireless receiving unit 22, a warning unit 23, and a display 24.
The radio frequency transmitting unit 21 transmits a wireless signal. In the embodiment, the wireless signal is transmitted in a digital code form. The radio frequency receiving unit 11 receives the wireless signal from the radio frequency transmitting unit 21, and generates a normal potential. In the embodiment, when the distance between the radio frequency transmitting unit 21 and the radio frequency receiving unit 11 is less than a preset value, the signal from the radio frequency transmitting unit 21 can be received by the radio frequency receiving unit 11. Otherwise, the radio frequency receiving unit 11 cannot receive the signal from the radio frequency transmitting unit 21. When not receiving the wireless signal from the radio frequency transmitting unit 21, the radio frequency receiving unit 11 generates an anomalous potential. In the embodiment, the radio frequency transmitting unit 21 and the radio frequency receiving unit 11 may be BLUETOOTH modules or WI-FI modules.
When the radio frequency receiving unit 11 receives the wireless signal from the radio frequency transmitting unit 21, the radio frequency receiving unit 11 generates the normal potential to signal the processor 16 to disable the detector 12. When not receiving the wireless signal transmitted by the radio frequency transmitting unit 21, the radio frequency receiving unit 11 generates the anomalous potential to signal the processor 16 to enable the detector 12.
The detector 12 detects the movement or the oscillation of the electronic device 10. In the embodiment, the detector 12 can be a 2-axis or 3-axis acceleration transducer. The default state of the detector 12 is DISABLED.
The storage unit 13 stores the warning information. The warning information may include acoustic information. In the embodiment, the warning information may further include text messages, such as “Warning!! Warning!! The electronic device is used by an unauthorized user”.
The camera 14 monitors a preset area where the electronic device 10 is placed. When the detector 12 detects that the electronic device 10 moves or oscillates, the processor 16 starts the camera 14 to capture video image of the preset area where the electronic device 10 is placed. In the embodiment, the camera 14 is only started when the detector 12 detects the monitoring electronic device 10 moves or oscillates, to minimize the consumption of the energy.
The wireless transmitting unit 15 can communicate with the wireless receiving unit 22 through conventional communication network, such as GPRS, or CDMA.
The warning unit 23 generates a warning. The warning may be audible and/or a vibration. The display unit 24 displays the text information.
The processor 16 controls the transmission of the signal, including warning information and the video data captured by the camera 14, through the wireless transmitting unit 15, when the detector 12 detects that the monitoring electronic device 10 moves or oscillates.
When the wireless receiving unit 22 receives the signal, the warning unit 23 generates the audible and/or the vibration according to the warning information of the signal, and the display unit 24 displays the video and the text information according to the warning information and the video data of the signal.
Referring to
In step S201, the radio frequency receiving unit 11 generates an anomalous potential to signal the processor to enable the detector 12 when not receiving the wireless signal transmitted by the radio frequency transmitting unit.
In step S202, the detector 12 detects whether the electronic device 10 moves or oscillates. If yes, the procedure goes to S203. If no, the procedure repeats.
In step S203, the processor 16 starts the camera 14 to capture video image of the preset area where the electronic device is placed, and controls the transmission of the signal including warning information and video captured by the camera 14 through the wireless transmitting unit 15.
In step S204, the wireless receiving unit 22 receives the signal including warning information and the video data captured by the camera 14.
In step S205, the warning unit 23 immediately generates an audible and/or a vibration according to the warning information of the signal and the display unit 24 immediately displaying the text information and the video according to the warning information and the video data of the signal.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
