1 Introduction
1.1 Document description
The purpose of this program is to let integrators, engineers and users understand the design concepts, principles, overall planning and how to play a huge role in asset management of IoT BLE technology, and elaborate on the working principles, installation locations and other information of related IoT devices. , So that integrators, engineering companies, and users can correctly understand the revolutionary changes brought by Bluetooth beacons in the asset field and the current shortcomings of the technology, and establish a correct understanding of the Internet of Things in the asset field.
2. System design
2.1 System construction composition
System composition based on BLE technology: Bluetooth beacon, Bluetooth base station;
Bluetooth base station: Installed and fixed on the door of the warehouse or on the wall of the warehouse to receive the radio frequency signal emitted by the Bluetooth beacon tag;
Bluetooth beacon: Bind to the item as its identification.
2.2 Significance of system construction
The wireless monitoring of valuables behavior through Bluetooth beacons and Bluetooth base stations can effectively warn and avoid theft.
Based on independent research and development
The core technology of the system construction adopts the standard Bluetooth BLE technology commonly used in the market. All the core equipment provided by the company have completely independent intellectual property rights. Bluetooth BLE 2.4G micro-power technology, Bluetooth base station self-organizing network technology, and synchronous transceiver mechanism are all The company’s original creation has greatly improved the service life and construction cost of Bluetooth beacon products, far exceeding the domestic industry level.
3. Description of the overall system design
Bind a Bluetooth beacon to each item on display. When someone touches, impacts, or vibrates, the Bluetooth tag will actively transmit (sensing threshold is adjustable) and send vibration data once every 1 second; the Bluetooth beacon will send the above status data information Actively transmit to the base station of sound and light alarm.
4. System function
Illegal movement alert
Certain valuables, unauthorized items such as position shifting, flipping, etc. will send out an alarm message.
