Description

Intelligent residential positioning device

The present invention relates to a smart home positioning device capable of continuously detecting and detecting a person who is indoors in a room environment through a heat source and sound wave detector installed in the room.

The difficulty of indoor positioning is that each environment is inconsistent. If the electromagnetic wave is simply used, it is easily interfered by the environment and surrounding objects. For example, in the process of beam emission and reception of infrared rays, it is easy to be interfered by excessive factors such as shielding, and it is easy to misjudge the situation. The two people staggered walking and moving around in many people also often misjudged, and could not accurately identify the user's true identity. Therefore, it is quite difficult to identify each user's identity in the indoor space and to locate it. Therefore, the sensing range using a single type of sensor as the identification and positioning is limited, and it is not suitable for the identification and positioning of indoor activity personnel.

For example, the invention patent "Indoor Positioning System" of the Republic of China No. I372260 includes a plurality of transmitters, which are disposed on the positioning tag and can transmit wireless signals of different codes; the receiving grid includes a plurality of signals receiving The receiving grid is constructed by constructing a square block for each of the four signal receivers; the processing module calculates the signal received by the signal receiver and filters it, and takes the three highest-intensity receivers of the four signals as effective. The reference point displays the structure of the signal receiving grid by the display device, and can simultaneously display the triangular block circled by the effective reference point; thus, the location of the indoor marking positioning label is substantially located. The above "indoor positioning system" It can only make the location of the person in the location of the indoor general location. The system cannot identify the person in the location. Therefore, the system is only suitable for the simple requirement of whether the indoor environment is active or not. In the case of a high positioning system with identity recognition, it is necessary to additionally use other identification devices. In the case of image comparison, the relative construction of the image is greatly increased. For example, it is necessary to record a clear image lens, a high image processing interface card, and a software and a computer capable of processing the above device.

In view of this, in order to improve the above single sensor, the user is positioned incorrectly. Defects in the situation, poor performance, and the use of image comparisons require high cost burdens and cannot be popularized. Research and product development of user positioning and identification technology, and after many tests and experiments, finally succeeded in creating a good recognition effect. It is not easy to misjudge, and it is cheaper than image recognition and positioning cost. Therefore, the establishment of this device is quite suitable for the industry, and it has become a practical invention with great promotion for indoor identification and positioning.

The invention provides a method for detecting indoor activities by using sound waves and heat source detection. After the detection value is obtained, the sound wave and the heat source data of the previously stored user are integrated and the result of the comparison is outputted to the user's identification signal, which not only achieves the purpose of indoor positioning and identification, but also clearly identifies the user through the above detection. The invention is not easy to misjudge the situation, and it is inherently cheaper than the image recognition and positioning.

In order to achieve the above objects and effects, the smart home positioning device of the present invention Installed in an indoor environment, a smart residential positioning device is installed in an indoor environment.

And detecting the sound wave value and the temperature value of the user respectively, and transmitting the detected sound wave value and temperature value to the sound wave data and physiology of the plurality of users stored in the identification storage unit 4 through the smart house processing unit 5 Temperature data comparison. The smart home processing unit 5 integrates the sound wave and temperature comparison result to obtain an identification signal of the user, so that the user identity and location can be obtained through the smart home storage unit 4, and the positioning and identification of the user in the room are achieved. Device requirements.

Referring to Figures 4 and 5, the present invention shows an indoor environment in the drawings. There are two-person use. In the initial state, the left user holds the mobile communication call and walks slowly toward the right side, while the right user walks toward the left side, and the two walk in the fifth picture to show the wrong walking situation. The sound wave detecting unit 2 and the heat source detecting unit 3 continuously detect the respective users, and the home sound processing unit 5 and the user sound wave value and the temperature detection value detected by the sound wave detecting unit 2 and the heat source detecting unit 3 are stored and stored in the identification. The user's sound wave data and physiological temperature data of the storage unit 4 are compared and the identification signal of the corresponding user is obtained, and the user identification number can be obtained before the wrong body. In the case of two people walking, the sound wave detecting unit 2 and the heat source are continuously passed.

Identity accuracy.

In addition, the lower the indoor ambient temperature, the more obvious the difference in temperature values of various parts of the human body. About 20 degrees Celsius in indoor environment, it can clearly distinguish the difference between the temperature of the trunk and the limbs. The temperature value of the limbs is lower than the value of the trunk temperature, so controlling the indoor ambient temperature is advantageous for the operation of the smart home positioning device of the present invention, so the smart home positioning device of the present invention can further control the indoor air conditioning system through the smart residential processing unit 5, thereby Stabilize the indoor ambient temperature to detect the body temperature of each user and improve the accuracy of the comparison.

In addition, the smart home positioning device of the present invention can be targeted by the heat source detecting unit 3 Indoor ambient temperature detection, the measured indoor ambient temperature is compared with the stored in the identification storage unit 4, the user temperature value stored in the appropriate previous indoor ambient temperature is selected, and the comparison accuracy between the detected temperature value and the stored temperature value is increased. .
