Problems solved by technology
The frequency of Bluetooth transmission data is not high, and it consumes less energy in the process of transmitting data. However, in order to respond to the connection request in time, the polling access during the waiting process is very energy-consuming.
[0009] (2) The Bluetooth connection process is cumbersome
The Bluetooth connection process involves multiple information transmission and verification processes. On the surface, it does not seem to make users feel the complicated connection procedures. However, the repeated data encryption and decryption process and the identity verification process required for each connection But it is a great waste of equipment computing resources
[0010] (3) Bluetooth security issues
In addition, the security of the encryption algorithm used in the process of Bluetooth data transmission needs to be improved

Embodiment Construction
[0054] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0055] The composition and practical basis of the Bluetooth system are explained first:
[0056] At present, the Bluetooth system composition technology mainly includes the underlying hardware module, intermediate protocol layer, advanced application, etc., which are introduced as follows:
[0057] a. The underlying hardware module
[0058] The underlying hardware modules in the Bluetooth technology system are managed by baseband, frequency hopping and link. Among them, the baseband is to complete the transmission of Bluetooth data and frequency hopping; the infinite frequency hopping layer is the microwave that passes through the 2.4GHz ISM frequency band without authorization, and the data stream transmission and filtering are realized in the wireless frequency modulation layer. The conditions that need to be met for the normal operation of...

Description
technical field [0001] The invention mainly relates to the technical field of smart electric energy meters, in particular to an intelligent electric energy meter device and a communication method thereof. Background technique [0002] The new generation of electric energy meters (IR46 modular electric energy meters) has higher and higher requirements for data communication. In my country's existing electric energy meter technology system, the communication part is currently mainly composed of communication modules (power line carrier, micro-power wireless, etc.), RS485 From the point of view of practical application, the two methods of RS485 and infrared have obvious defects, such as RS485 wiring construction is difficult, communication speed is low; infrared communication is unreliable and slow, these two technologies are obviously not suitable for the future According to the development trend of energy meter technology, a high-speed and reliable local communication technolog...
