Embodiment Construction

[0026] As mentioned in the background technology, the existing monitoring, tracking and management system for smart objects based on wireless sensor networks is not only not convenient enough to use, but also cannot analyze the traveling trajectory in real time, and the effect is not good.

[0027] Next, the specific technical solution of the present invention will be introduced in detail.

[0028] See Figure 1 ~ Figure 2 , in areas to be monitored, such as homes and offices, multiple miniature pressure sensors are deployed. The deployment locations mainly include the floor and under the wall wallpaper. In order to obtain accurate information, a large number of sensor nodes are usually deployed in the monitoring area, which may reach hundreds of Thousands, maybe even more. These miniature pressure sensors are the nodes in the wireless sensor network. These nodes form a wireless network through self-organization, perceive, collect and process specific pressure information in ...

Abstract

The invention provides a three-dimensional position induction system. Multiple pressure sensors are arranged in a monitoring area so that multiple nodes of a wireless sensor network are formed. The wireless sensor network comprises a pressure acquisition module, a data processing module, a wireless communication module, a data analysis module and a power supply module. Pressure generated by moving and touching of people is monitored via the pressure acquisition module, and data information obtained from the pressure acquisition module is acquired via the data processing module. The generated analog voltage signals are converted into digital signals, and then the digital signals processed by the data processing module are wirelessly transmitted to the background in real time via the wireless communication module. The data analysis module positioned at the background analyzes the positions or the moving tracks of people in real time through data processing of a computer. The positions or the moving tracks are recorded and analyzed for a long term according to time. The three-dimensional position induction system and method can be widely applied to multiple purposes of home nursing and other aspects of intelligent household so that the three-dimensional position induction system and method have advantages of being low in cost, great in effect and convenient to use.

Description

technical field [0001] The invention relates to the fields of pressure sensors and wireless sensor networks, in particular to a three-dimensional position sensing system and method based on a wireless sensor network formed by pressure sensors. Background technique [0002] Sensor technology is one of the important technologies of modern measurement and automation systems. Among various types of sensors, pressure sensors are the most commonly used sensors in practice. Its working principle is to sense the pressure and convert it into an available output signal, which can be widely used in the measurement and control of pressure, height, acceleration, liquid flow, flow velocity, liquid level, and pressure. The main application fields include water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, geology, meteorology, chemical industry, medical and health, petrochemical, electric power, shipbuilding, machine tools and m...
