Old-age community positioning system

1. Status Analysis of Pension Apartments

Under the background of an aging population in China, to meet the ever-escalating needs of elderly care, the construction of elderly apartments and elderly care communities is accelerating. The security management in elderly apartments faces the following issues for operators:

1 As there are many indoor and outdoor activity areas in the community and institutions, once the elderly people encounter sudden situations such as wrestling or illness in the course of their activities, they can't inform the stewards to help them for the first time. They can only choose to wait or find their own way.

2 The traditional RFID technology in the area of ​​personnel positioning is difficult to meet the requirements of no-dead-pocket positioning in the park because of regional positioning. However, the cost of ultra-wideband positioning technology is difficult to promote in the civil sphere. The industry needs a highly cost-effective positioning product to meet the use of intelligent pension programs.

3 In terms of management, the informationization of apartments for the elderly is generally viewed using property-based surveillance cameras, and cannot be proactively prevented and prevented. There is no practical safety incident report for the handling of the causes of the accident, and it is not possible for elderly family members and the leaders of the institute. Forming a systematic explanation is also not conducive to forming a basis conducive to the establishment of a security system.

4 Group-type pension apartments or chain-style pension apartments plan for the project function area is only the project designer's experience to regulate, function area selection and support can not be in accordance with the elderly's real activity data to think, which functional areas are welcomed by the elderly Frequently, what are the visits to the elderly in the functional areas of the week, month, and year, and the lack of detailed data on areas where different types of old people frequently work are not conducive to the extension and improvement of follow-up pension programs? .

The company relies on the industry's top wireless communication experts and data security development team to integrate the world's most advanced 2.4G high frequency communication technology, antenna technology, optical communication technology, embedded technology, industrial Ethernet transmission technology, database processing technology, computer software Technology, GIS technology, Internet technology and other multi-disciplinary integrated research projects, research and development and construction of this set of intelligent pension security alarm management system. This system uses the Internet of Things zigbee radio frequency identification technology to achieve automatic identification, location tracking, early warning and automatic alarm, emergency command and regulate the behavior of the stewards, the use of safe and reliable information collection methods, and personal information and reality in the information system The individuals are truly linked to achieve real-time tracking and alerting. At the same time, the system also summarizes the big data information such as the old man's safety accident report and the project's functional area activity analysis report, so that operation managers can make analysis and decision making. Only in this way can we realize the informationization, intelligence, and standardization of management of pension apartments, and realize the “management of science and technology”.

5.1 Positioning Technology Comparison

With the advent of the age of wisdom and support for the elderly, in order to avoid the occurrence of personnel safety incidents, the middle and high-end elderly care communities are gradually equipped with personnel positioning systems. There are many kinds of positioning technologies for people, but there are still a lot of differences between technologies. In the outdoors, GPS can be used to locate people. However, indoor GPS signals cannot be used normally due to blockage of buildings, interference of signals from reinforced concrete, and low positioning accuracy. Here we look at the advantages and disadvantages of commonly used technologies:

1, WI-FI technology

The Wi-Fi positioning application employs the placement of a wireless base station in the area, and comprehensively determines the coordinates of the Wi-Fi equipment to be located based on the signal characteristics of the Wi-Fi equipment to be located, combined with the topology structure of the wireless base station. Wi-Fi positioning technology facilitates the use of existing wireless devices to implement the positioning function. However, due to the poor security of Wi-Fi, high power consumption, and spectrum resources approaching saturation, it is not conducive to long-term carrying and large-scale terminal equipment. Scale application.

2. Radio frequency identification (RFID) technology

It uses the principle of electromagnetic induction to wirelessly excite short-range wireless tags to realize information reading technology. Radio frequency identification distance from a few centimeters to ten meters. The typical application of RFID for personnel positioning comes from the expansion of personnel attendance systems, mainly to identify whether people exist in a certain area, can not be tracked in real time, and the positioning application does not have a standard network system, therefore, does not apply to large-scale equipment Patrols, confirmation of personnel safety, etc.

3, UWB technology

UWB (Ultra Wideband) is a carrierless communication technology that uses nanosecond to microsecond non-sinusoidal narrow pulses to transmit data. It typically uses the TDoA (Time Difference of Arrival) and ToF (Time Arrival) algorithms to implement information on the location of people or objects. . In addition, the UWB technology for the desired positioning of objects or personnel requires the laying of base stations and the wearing of tags. UWB technology can achieve a centimeter-level positioning level, but the positioning cost is high. It is suitable for industries with small positioning area and high economic value added. There are many millions of inputs in the factory field, and there is a bit of centimeter-level positioning for people. It is only for small use."

4, ZigBee positioning technology

ZigBee is a low-power LAN protocol based on the IEEE 802.15.4 standard. Its characteristics are close range, low complexity, self-organization, low power consumption, and low data rate. Mainly suitable for automatic control and remote control applications. It is its characteristics in the industrial field, its interference, low power consumption, full duplex, free wiring and other characteristics, it has the basic performance of the positioning system, which can achieve high cost performance after the communication protocol stack and algorithm processing Label positioning system. Positioning accuracy of up to 3m, local area accuracy of 1m, fully meet the needs of personnel positioning in the factory area under the premise of cost control.

5.2 Introduction to Positioning Mechanism

Firstly, the single-point sensing positioning, two-point linear positioning and three-point plane positioning are integrated, and the positioning is adjusted according to the position of the base station. Strategy to ensure the positioning effect in the replication environment. Second: The system does not rely solely on RSSI signal values ​​for processing. At the same time, it uses an advanced time-of-flight algorithm (TDoA) to optimize the signal processing so that the wireless signal is not interfered with by external factors to a great extent.

Zigbee technology networking and positioning have the following advantages:

High positioning accuracy: The company positioned the original zigbee protocol stack for upgrade optimization, positioning accuracy of 3 meters, local positioning accuracy of 1 meter, fully meet the factory's demand for real-time location of workers.

Data Security: The unique 128k encryption algorithm of Zigbee technology has strong anti-interference ability, which can prevent data leakage and wireless signal interference.
