Problems solved by technology

[0005] (1) Due to the complexity of the environment in actual use, the detector is easily affected by strong light, electromagnetic radiation, and ambient temperature, which interferes with the detection effect, and often leads to missed detection and false detection.
Therefore, existing human intrusion detectors are prone to false alarms and can only be used indoors.
[0006] (2) When human body intrusion detection is used for indoor anti-theft, the purpose is mostly to detect illegal entry, window intrusion, etc., but since it has only one sensor, all changes in thermal energy within the coverage area of ​​its sensing signal are considered effective for detection , so it can only know whether it is close to or far away from the detector, and cannot detect the direction of people's activities; moreover, if the doors and windows are not closed properly, and the wind blows through the doors, windows or some vents, false alarms will occur
[0007] (3) There are also infrared + microwave or infrared + ultrasonic and other similar dual-identification technologies on the market to solve the problem of false alarms caused by wind, etc., its stability has been greatly improved, and the rate of false alarms has been greatly reduced; but it cannot be identified. Whether the human activities of the detector are caused by the normal activities of the owner or the activities of illegal intruders, this will cause the problem that the owner will also alarm during normal activities, resulting in false alarms, so many families want to install intrusion detectors, but after installation I will call the police when I am at home, which makes me inconvenient, so I can't really promote it

Embodiment 1

[0056] Lite Mode: Combine Figure 10 , the working process of the detector is as follows:

[0057] (1) start, that is, the detector enters the normal working state;

[0058] (2) Detect whether it is in test mode, if it is test mode, then enter step (3), if not, then enter step (4);

[0059] (3) Whether the detection delay is completed, if completed, then enter step (4), if not completed, then start or continue the delay timing, and automatically return to step (2), start the next cycle, (2), ( 3) The two steps avoid the false alarm of the detector in the test mode;

[0060] (4) Detect whether the sensor is active or not. If the sensor is active, go to step (5). If the sensor is not active, then automatically return to step (2) to start the next cycle. Since the cycle is very short, it can be considered that the detector is The detection area of ​​the sensor realizes uninterrupted detection;

[0061] (5) Combining the action time of the two groups of human body sensing comp...

Embodiment 2

[0065] Integration Mode: Combine Figure 11 , the working process of the detector is as follows:

[0066] (1) start, that is, the detector enters the normal working state;

[0067] (2) Detect whether the power is insufficient. If the power is insufficient, an alarm signal for insufficient power will be sent, and the power will be automatically cycled to detect the power until the user solves the problem of insufficient power by charging or replacing the battery. If the power is sufficient, then enter step (3);

[0068] (3) Detect whether the tamper is triggered or not. If a tamper trigger signal is detected, go to step (9) to trigger an alarm. If no tamper trigger signal is detected, go to step (4). If an illegal intruder destroys the detector, the alarm will be triggered immediately;

[0069] (4) Detect whether it is in test mode, if it is test mode, then enter step (5), if not, then enter step (6);

[0070] (5) Whether the detection delay is completed, if completed, then ...

Abstract

The invention discloses a human body invasion detector capable of intelligent analysis. The detector comprises a central processor, human body sensing assemblies and an alarm device; the human body sensing assemblies are respectively two groups of infrared sensing assemblies; signal output ends of the human body sensing assemblies are connected with a sensing signal input end of the central processor; and an alarm signal output end of the central processor is connected with a signal input end of the alarm device. The invention also discloses a detection method of the detector, which comprises the following steps of: starting; detecting a test mode; detecting a delay; detecting whether a sensor works or not; analyzing a direction of motion; comparing whether the direction of motion is in accordant with an alarm mode or not; sending an alarm code and returning to the start; and circulating the above steps. Through the adoption of the invention, whether a person who passes through the human body invasion detector is an illegal invader or the owner of the detector can be accurately judged and an alarm is executed; meanwhile, no error alarm is caused by non-human factors, such as blow, sunlight, light irradiation, and the like.

Description

technical field [0001] The invention relates to an intelligent analysis human body intrusion detector capable of accurately judging whether a person passing through the human body intrusion detector is an illegal intruder or an owner and a detection method thereof, belonging to the production field of human body intrusion detectors. Background technique [0002] The human body intrusion detector uses the human body sensor as the sensor. After the sensor senses the human body signal, it transmits the signal to the central controller, and the central controller sends corresponding instructions to the execution terminal, such as alarm instructions, display instructions, voice instructions, and door opening. instructions etc. [0003] Taking infrared detectors as an example, the existing infrared detectors use pyroelectric infrared sensors to detect the temperature difference caused by the movement of animals (mainly people) within the effective range, and identify the direction...
