Problems solved by technology

For this reason, the main purpose of the present invention is to provide a human body induction static alarm system, which aims to solve the problem that the existing alarm system needs to record human body contour data through human body contour detection and alarm, and cannot find objects lacking movement and temperature change. Problems and the problem of inaccurate measurement due to the high error rate of people other than the human body cannot be ruled out when combined with pyroelectric infrared sensors

Embodiment 1

[0038] like figure 1 As shown, a human body induction static alarm system includes an infrared detection unit 1, a main control unit 2 connected to the infrared detection unit 1 and an alarm unit 3 connected to the main control unit 2;

[0039] refer to Figure 1 ~ Figure 3Among them, the infrared detection unit 1 emits equidistant infrared beam sets 12 to measure objects with different temperature differences in the measurement area 4, and the temperature detected by the infrared beam set 12 is fed back to the main control unit 2, and the main control unit 2 detects the same The area of ​​the object to be measured is obtained by the number of infrared beams 11 of temperature, and by comparing the preset human body temperature range and area range in the main control unit 2, it is judged whether there is an object with the same preset value in the measurement area 4, and the Whether the object is in a static state, in a static state, the main control unit 2 sends a signal to ...

Embodiment 2

[0062] refer to Figure 8 and Figure 9 The difference from the above embodiments is that the emitting end 13 of the infrared detection unit 1 is a circular frustum structure, the detection angle is 82°, and the maximum detection area is 5.6mx6.6m.

Abstract

The invention discloses a human body induction static alarm system comprising an infrared detecting unit, a main control unit connected to the infrared detecting unit and an alarm unit connected withthe main control unit. The infrared detecting unit emits an infrared beam set to measure an object in a measuring area; the temperature and area values detected by the infrared beam set are fed back to the main control unit; the temperature and area values are compared with a preset temperature value and a preset area value in the main control unit to determine whether an object having values thesame as the preset values exists in the measuring area is determined; whether the object is in a static state is determined; and if so, the main control unit sends a signal to the alarm unit and the alarm unit carries out alarming. Therefore, problems that the human body contour data that need to be recorded for body contour detection alarming are massive and objects that are lack of movement andhave no temperatures changes can not be discovered according to the existing alarming system and problems that the error rate is high and measurement accuracy is low because people except the body cannot be eliminated by combining the pyroelectric infrared sensor are solved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a human body induction static alarm system. Background technique [0002] With the development of society and technology, population mobility increases, and the number of children in the family decreases. There are many empty-nest families in our country where the elderly have no children or their family children are not around for various reasons, especially in some large-scale families in my country. There are more empty-nest families in cities such as Shanghai, Beijing, and Guangzhou. And this situation becomes more and more serious as time goes by. With the increase of age, the physical function of the elderly will gradually decline, and the activities of the elderly will become more and more inflexible. Some accidents often occur, and the probability of accidental falls of the elderly is very high. Especially the situation that some elderly people living alon...
