Introduction to the Basic Principles of Positioning Technology
Nowadays, one parameter is missing from many scenarios, car rental, assets in warehouses, packages and containers in logistics, hospital personnel, and people who are injured but cannot be reached in an accident (chemical factory, mining site). This parameter connects and automates many processes that fall apart before, improves efficiency and safety, and lowers the cost of the total flow, which in turn improves the competitiveness of the organization, customer satisfaction, and comfort of employees. It can widely used in industry, agriculture, logistics, consumer electronics, and aerospace.
It is the POSITION, the purpose of asset and people tracking.
Actually, the requirements for the position were there. The new technologies make them possible now. The technologies are: Communication, Sensor, Battery, Cloud Computing, Semiconductor.
Tracking products and solutions combine the ones above along with positioning technologies. The typical positioning technologies are based on sound, light, electricity, magnet, and inertia.
Even though there are varieties of derived technologies based on these theories, no one is the best because it differs for each use case.
This paper briefly introduces the basic principles, the pros, and the cons of each principle. It mainly introduces wireless technologies and use cases to help readers select the most appropriate positioning technology and solution for industrial use.
Bluetooth Technology and Common Terms Introduction
The Bluetooth we often talk about in our daily life actually refers to BLE (Bluetooth low energy technology). As the name suggests, the current Bluetooth technology consumes very low power.
Unlike the rumours saying that Bluetooth needs to be turned off to save power when not used, Bluetooth or the power consumption of turning on Bluetooth on the mobile phone for a long time is negligible. In IoT devices, beacons transmit at a fixed interval, and the power consumption is low. Compared with transmitting, in IoT application, Bluetooth receiving consumes more power.
