System Introduction

System composition
The indoor location system is composed of a web application platform, location engine, anchors, and tags.

Introduction

Tag
The tag is the terminal of the UWB location system, which is mainly responsible for periodically sending location messages to the anchor and receiving setting messages from the anchor.
Anchor
The UWB anchor is an important part of the whole location system. Its main function is to receive and parse the information reported by the tag and then transmit it to the location engine. The anchor deployment has a direct impact on the location accuracy of the entire system, so special attention should be paid to the selection of anchor location. The following sections will specify the deployment principles of anchor location selection.
Location engine
The function of the location engine is to receive the location message after the anchor is parsed, and calculate the anchor location through a certain algorithm, or send some parameter configuration information to the anchor.
Web application platform
Web application platform is an upper application based on the development of location data. Users can directly use the functions provided by the Web application or customize the development based on the secondary development interface provided by the Web platform.

Introduction of location mode

Location System Architecture

Indoor positioning system has three modes:

• Zero-dimensional positioning mode (existential positioning)
• One-dimensional positioning mode
• Two-dimensional positioning mode
  1. Zero-dimensional positioning mode
  Zero-dimensional positioning mode, also known as existential positioning, refers to that when a tag enters a specific positioning area, the positioning system only identifies the presence of the tag in the area but does not judge the specific location of the tag. It is a kind of coarse precision positioning, which is generally suitable for the small-enclosed areas.
  2. One-dimensional positioning mode is used to locate only one dimension in a three-dimensional world, also known as “linear positioning”. When the tag enters the one-dimensional positioning area, the system can accurately locate the tag on a straight line, which is generally applied in narrow and long areas such as tunnels and corridors.
  3. Two-dimensional positioning mode refers to the positioning of two dimensions in a three-dimensional world, also known as “planar positioning”. When the tag enters the two-dimensional positioning area, the system can accurately locate the planar position of the tag. It is often used in offices, warehouses, factories and other large areas, and is the most commonly used positioning mode of the indoor positioning system.

Anchor selection and installation

Anchor selection
To a large extent, the selection of the tag installation location determines the difficulty of debugging and the final positioning effect, so the following principles should be referred to during the selection.

1. Zero-dimensional positioning is often used for smaller enclosed areas with physical boundaries and entrances. For example, a room is often used as a zero-dimensional area. After leaving the zero-dimensional area, you can enter the higher dimensional area. For example, after leaving the room, you can enter the corridor (one-dimensional positioning) or the office (two-dimensional area).
   When the anchor is selected in the zero-dimensional region, the center of the zero-dimensional region is selected as the location of the anchor
   

2. One-dimensional positioning
   The following conditions should be satisfied when planning the one-dimensional positioning region.

   The space between every two anchors in the positioning area is less than 40m (up to 80m in the especially open area)
   No shielding between anchors
   Anchors need to be installed in the front and at the end of the one- dimensional area
   If more than two anchors are installed in the one-dimensional positioning area (for example, the length of the area is more than 40m), the anchor in the middle is located on the boundary between the two regions and can be reused by the two regions. As shown in the figure below, the anchor located in the middle can be shared by Regionl and Region2.
   

3. Two-dimensional positioning
   Two-dimensional positioning is usually used in spaces with an area of more than 100 square meters, such as large factory areas, large conference rooms, halls, etc. The positioning area is divided into several two-dimensional positioning parts. These areas shall meet the following requirements

   Rectangle, length to width ratio is 1:1, the maximum is not more than 3:1
   The long side of the rectangle should not be greater than 35m (in open space, the length of the side can be extended to 50m)
   There are no walls, columns, storage shelves, cabinets, sky-type machinery, etc. The height of the equipment in the area shall not be greater than 1.5m; if there are above objects in the rectangular area, the accuracy of two- dimensional positioning will be reduced and the distance between anchors will be reduced accordingly.
   For each two-dimensional positional area, at least four anchors need to be installed, respectively installed in the four corners of the area. If two positioning areas are interlinked, then the anchor located on the dividing line of two cells can be reused by the two areas.
   Generally, a complex area will also contain a one- dimensional/two-dimensional/zero-dimensional positioning, for zero dimension in the meeting room, one dimension in the corridor, two-dimension in the office or the hall. An overlap area should be set at the junction of one- dimensional and two-dimensional areas to ensure the fluency of switching between the two areas.
   

Anchor Installation
After the location of the anchor is selected, the next step is to install the anchor. During the installation, the principles below should be followed.

• The anchor should be more than 30cm away from the wall, or 50cm away from the metal wall.
• The height of the anchor to the ground is generally between 3m and 5m
• The anchor must leak out, not be embedded in the ceiling and away from metal objects.
• Indoor anchor must be installed with body face down

Indoor anchor installation and debugger Install the indoor anchor with the raised side of the anchor facing down, as shown in the figure below.
Record the location and ID number of the base station during installation, so that the anchor coordinates can be set when the system is debugged.

Indoor Positioning Base Station Application Scenarios

Application Scenarios: Hi-tech Building, Hotel, Office, Swimming Center, Kindergarten, Home, etc. Real-time positioning of children; Electronic fence; Electronic attendance; Emergency management; danger warnings; SOS; Visitors flow calculation; Drowning alarm; Provide the elderly with real-time positioning and nurse can rescue in time in case of emergency, etc.

Network Setting Up

In the general environment, all anchors in this layer can be networked by POE switch of the access layer, and then connected to the core layer switch by means of optical fiber or network server.
Depending on the selected network architecture, each anchor needs a separate network cable connected to the switch, and the other end is fixed in a pre- reserved anchor location.

Note:

1. Recommended to use more than five types of network cable
2. Pull the network cable head to the anchor design point, and make a wire loop with a preset length margin of 1-2m, and place it at the point.
3. The two ends of the network must be marked with tags in order to find the two ends of the same network cable
4. The distance from the switch to the anchor should not be more than 90m, if more than 90m, please add a POE switch in the middle to avoid abnormal power supply of the base station.
5. At this point, the basic engineering installation of the UWB positioning system is completed, and the next step is the installation and debugging of the UWB positioning software system.
