Overview of BLE Bluetooth application scheme

Bluetooth low power (BLE) technology has become an ideal choice for local communication of prepaid electric meters due to its advantages of low cost, easy networking and high compatibility. The traditional IC card prepayment meter requires users to recharge their cards in the business hall or write cards through self-service terminals, which is cumbersome to operate and cannot monitor the electricity consumption data in real time. The BLE Bluetooth application scheme has completely changed this mode. Users can establish Bluetooth connection with the electricity meter through the mobile APP or applet, and complete remote recharge. The whole process is convenient and efficient, which greatly improves the user experience. At the same time, BLE's local networking capability enables multiple meters to form a mini-network, which can realize low-cost data acquisition and power consumption monitoring without additional wiring, and provide real-time and accurate power consumption data for power departments and properties.

 

The BLE module is embedded in the electric meter, so that the user can authenticate and recharge by Bluetooth when he is close to the electric meter, without touching the electric meter entity, thus avoiding the problem that the IC card is easy to be lost and worn. BLE Bluetooth application scheme Through BLE self-organizing network technology, a star or mesh network can be automatically formed between electric meters, and the concentrator (such as equipment with Bluetooth gateway) collects the electricity consumption data of all electric meters regularly, so as to realize low-cost and high-efficiency automatic meter reading. Yingshangwei BLE Bluetooth application scheme is suitable for intensive deployment scenarios such as apartments, residential quarters and industrial parks. Compared with NB-IoT or Cat.1 scheme, it does not need to pay communication fees, which significantly reduces operating costs. When the electric pulse is used for external interrupt monitoring through GPIO, the electric meter needs to ensure the timeliness of interrupt response and avoid packet loss while writing the data recorded in Flash. The high-performance processing ability of BLE chip can easily cope with such concurrent tasks, ensuring accurate measurement.

 

BLE Bluetooth Application Scheme Description

•BLE is convenient for users to recharge directly, which is much more convenient than the traditional IC card method.

•BLE can use local networking to realize low-cost centralized reading/monitoring of users' electricity consumption.

•Bleota facilitates firmware maintenance and solves problems.

•BLE Bluetooth application scheme has no low power consumption requirement.

•Use ble local networking centralized copy, and individual users need NBIOT/cat1 centralized copy.

•If the power consumption is calculated by GPIO external interrupt, it can respond to the interrupt when writing flash.

•Some have LCD requirements.

 

BLE Bluetooth Application Scheme Advantages:

•Provide flexible local networking mode to facilitate customers' realization.

•Local centralized copy.

•Single chip solution of •BLE+LCD.

•BLE Bluetooth applications have a large number of successful cases.
