Abstract

Official abstract text for this publication.

An active protection system for protecting an object includes a first lens, a second lens, a processing unit and an alarm unit. The first lens is configured to receive first light and generate a first image. The second lens is configured to receive second light and generate a second image. The processing unit is configured to obtain a characteristic value of the object from the second image, determine whether the characteristic value reaches a pre-set value, and judge whether the object is regulated in a predetermined period after the characteristic value reaches the pre-set value. The alarm unit is configured to raise an alarm under control of the processing unit if the object is not regulated in the predetermined period after the characteristic value reaches the pre-set value.

First claim

Opening claim text (preview).

What is claimed is: 1. An active protection system for monitoring an object, comprising: a first lens configured to receive first light and generate a first image; a second lens configured to receive second light and generate a second image; a processing unit configured to obtain a characteristic value of the object from the second image, determine whether the characteristic value reaches a pre-set value, and judge whether the object is regulated in a first predetermined period of time after the characteristic value reaches the pre-set value based on the first image; an alarm unit configured to raise an alarm under control of the processing unit if the object is not regulated in the predetermined period of time after the characteristic value reaches the pre-set value; and a communication unit configured to connect to a terminal device through a network, wherein the processing unit sends an alarm signal to the terminal device when the characteristic value reaches the pre-set value; wherein the processing unit sends a first control signal if receiving no response from the terminal device in a second predetermined period after the alarm signal is sent, the active protection system further comprises a signal transmitting unit configured to transmit the first control signal to a control device, and the control device is configured to regulate the object so that the characteristic value becomes less than the pre-set value when the control device receives the first control signal; and wherein the terminal device is configured to send a second control signal through the communication unit to the processing unit, and the processing unit sends the first control signal, when receiving the second control signal. 2. The active protection system as claimed in claim 1 , wherein the first light comprises visible light. 3. The active protection system as claimed in claim 1 , wherein the second light comprises infrared light. 4. The active protection system as claimed in claim 3 , wherein the characteristic value is temperature of the object. 5. The active protection system as claimed in claim 1 , wherein the first lens has a higher pixel resolution than the second lens. 6. The active protection system as claimed in claim 1 , wherein the first lens is closed in a condition that the characteristic value is less than the pre-set value, the second lens is operated at all times to receive the second light and generate the second image, and the processing unit actuates the first lens to receive the first light and generate the first image when the characteristic value reaches the pre-set value. 7. An active protection system for monitoring an object, comprising: a first lens configured to receive first light and generate a first image; a second lens configured to receive second light and generate a second image; a processing unit configured to obtain a characteristic value of the object from the second image, determine whether the characteristic value reaches a pre-set value, and judge whether the object is regulated in a first predetermined period of time after the characteristic value reaches the pre-set value based on the first image; and a communication unit configured to connect to a terminal device through a network, wherein the processing unit sends an alarm signal to the terminal device if the object is not regulated in the first predetermined period of time after the characteristic value reaches the pre-set value; wherein the processing unit sends a first control signal if receiving no response from the terminal device in a second predetermined period after the alarm signal is sent, the active protection system further comprises a signal transmitting unit configured to transmit the first control signal to a control device, and the control device is configured to regulate the object so that the characteristic value becomes less than the pre-set value when the control device receives the first control signal; wherein the terminal device is configured to send a second control signal through the communication unit to the processing unit, and the processing unit sends the first control signal, when receiving the second control signal. 8. The active protection system as claimed in claim 7 , wherein the first light comprises visible light. 9. The active protection system as claimed in claim 8 , wherein the characteristic value is temperature of the object. 10. The active protection system as claimed in claim 7 , wherein the second light comprises infrared light. 11. The active protection system as claimed in claim 7 , wherein the processing unit sends the alarm signal and the first image to the terminal device when the characteristic value reaches the pre-set value. 12. The active protection system as claimed in claim 7 , wherein the processing unit is further configured to combine the first image and the second image to a composite image. 13. The active protection system as claimed in claim 12 , wherein the processing unit sends the composite image and the alarm signal to the terminal device when the characteristic value reaches the pre-set value. 14. The active protection system as claimed in claim 7 , wherein the communication unit is connected to the network, either wirelessly or via cable. 15. The active protection system as claimed in claim 7 , wherein the first lens has a higher pixel resolution than the second lens. 16. The active protection system as claimed in claim 7 , wherein the first lens is closed in a condition that the characteristic value is less than the pre-set value, the second lens is operated at all times to receive the second light and generate the second image, and the processing unit actuates the first lens to receive the first light and generate the first image when the characteristic value reaches the pre-set value.
