Problems solved by technology
[0002] In my country's existing power distribution communication technology system, the communication part is currently mainly realized by communication modules (power line carrier, micro-power wireless, etc.) and RS485. From the perspective of practical applications, there are obvious defects in the two methods of RS485 and infrared. For example, RS485 wiring construction is difficult and communication speed is low; at present, a high-speed and reliable local communication technology is urgently needed to replace RS485 and other technologies

Embodiment Construction
[0014] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them.
[0015] First, the composition and practical basis of the Bluetooth system are explained:
[0016] At present, the Bluetooth system composition technology mainly includes the underlying hardware module, intermediate protocol layer, advanced application, etc., which are introduced as follows:
[0017] a. The underlying hardware module.
[0018] The underlying hardware modules in the Bluetooth technology system are composed of baseband, frequency hopping and link management. 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 transmi...

The invention discloses an Internet of Things communication system based on Bluetooth communication and a communication method thereof. The communication system comprises a communication unit, end equipment, a terminal module and a Bluetooth module, wherein the Bluetooth module adopts one of two modes of a Bluetooth module and an SOC mode; when the Bluetooth module is adopted, the Bluetooth module comprises a first Bluetooth module and a second Bluetooth module, and the communication unit is connected with the end equipment through the first Bluetooth module; the communication unit is connected with the terminal module through the first Bluetooth module and the second Bluetooth module in sequence; when the SOC mode is adopted, the communication unit is connected with the end equipment and the terminal module through integrated Bluetooth of the communication unit; when the communication unit works in a one-master multi-slave mode, the communication unit is used as a host, and the communication unit initiatively initiates data connection with the end equipment; and when the communication unit is used as a slave, the communication unit receives a connection request from the terminal module to carry out Bluetooth communication. The invention has the advantages of very low static and dynamic communication power consumption, high safety and reliability, good stability and the like.
Description
technical field [0001] The invention belongs to the technical field of electric power internet of things, and in particular relates to a communication system of the internet of things based on bluetooth communication and a communication method thereof. Background technique [0002] In my country's existing power distribution communication technology system, the communication part is currently mainly implemented by communication modules (power line carrier, micro-power wireless, etc.) and RS485. From the perspective of practical applications, the two methods of RS485 and infrared have obvious defects. For example, RS485 wiring construction is difficult and the communication speed is low; at present, a high-speed and reliable local communication technology is urgently needed to replace RS485 and other technologies. [0003] Bluetooth technology has been upgraded in several versions, and has been widely used in the field of Internet of Things. It is a mature communication techno...
