Low-power-consumption remote transmission system and control method thereof

Abstract

The invention relates to the technical field of communications, in particular to a low-power-consumption remote transmission system comprising a microcontroller and an RF (radio frequency) chip. The microcontroller comprises a Bluetooth chip; information transmitted by the Bluetooth chip is processed by the microprocessor and sent out by the RF chip; the RF chip receives the information which is processed by the microprocessor and which is output to the Bluetooth chip. The invention further relates to a control method of the low-power-consumption remote transmission system. The low-power-consumption remote transmission system and the control method thereof have the advantages that a transmittable range of Bluetooth is enlarged from 100m to 3Km, RF signals are packaged according to the international standard, software structure and codes are both redefined, safety is high, RF signal transmittance is good, anti-interference capability is high, and transmission reliability of Bluetooth data is further enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a low-power long-distance transmission system and a control method thereof. Background technique [0002] Bluetooth (Bluetooth) technology is a radio technology that supports short-distance communication (generally within 10m) of devices. Using Bluetooth technology, it can effectively simplify the communication between mobile communication terminal devices such as handheld computers, notebook computers and mobile phones. It can also successfully simplify the communication between the above-mentioned devices and the Internet, thereby making the data transmission between these modern communication devices and the Internet more rapid and efficient, and widening the road for wireless communication. Bluetooth technology enables some modern mobile communication devices and computer devices that are easily carried to be connected to the Internet without cables, and can realize wi...

Problems solved by technology

[0003] However, Bluetooth technology also has limitations: the transmission distance is short

There are many deficiencies in increasing the transmission distance by increasing the transmission power of the Bluetooth device: 1. The transmission distance still cannot meet the industrial needs; 2. When the signal circuit is amplified, the noise signal is amplified at the same time, which will reduce the reliability of data transmission; 3. The transmission frequency of Bluetooth signals is 2.4G, which is a high-frequency signal and is easily interfered by external factors such as climate and construction; 4. This design increases the transmission power of Bluetooth, which will inevitably bring high power and high radiation

The above limits the development of Bluetooth, and it is doomed that Bluetooth can only become a family and small area communication transmission solution, which cannot meet the requirements of modern industry, and control and communicate with long-distance and ultra-long-distance communication terminals.
