Physical Design
The CJ-IB10-EX is strong and can withstand all kinds of harsh/dangerous environments, making it suitable for chemical, mining, medical, and other industries. It is easy to install with a reliable structure design and can be installed on the wall/road/ceiling, etc.

Function Description

The CJ-IB10-EX is used to achieve the overall design goal system of personnel positioning. The system will use some beacons to be fixed where the human will pass, its own unique MAC address or Device EUI (each MAC/EUI address corresponds to a certain point in the map location), and battery voltage information. In addition to the MAC/EUI address and battery capacity, UUID, major, and minor information are also sent for flexible configuration and sorting of the cloud computer. Beacons themselves are major and minor(unique), which can be written at production time (Jlink command) and stored permanently. The product has an active detection of beacon voltage, and the battery shall be replaced if the battery’s power energy is less. The uploaded data can be encrypted using the DES encryption standard and cannot be identified by other systems. The CJ-IB10-EX also has an extensible RFID function for clocking/identification.

Usage Instructions

To use the CJ-IB10-EX Bluetooth beacon, follow these instructions:

1. Install the CJ-IB10-EX on a wall, road, ceiling, or other surface.
2. The beacon will send its own information to a work card, including the MAC address and battery quantity of electricity, for marking the position of geographical.
3. The work card will collect the message and upload it to the base station via the network.
4. The battery shall be replaced if the battery’s power energy is less.
5. The uploaded data can be encrypted using the DES encryption standard and cannot be identified by other systems.
