1. ZigBee module

ZigBee is a kind of short-range wireless network communication information technology, and Bluetooth control technology to carry out similar. However, compared with the Bluetooth technology, ZigBee has many resource advantages in China, such as simple layout structure,wireless module strong anti-jamming ability, high reliability of the transmission system, the use of which can be convenient, low cost and price, etc. The communication distance of ZigBee is 10 meters, the space distance can be up to hundreds of meters, and the indoor distance is about 50 meters. With the development of economy and society, the demand of enterprises for industrial production automation is also higher and higher, and Bluetooth technicians can't get to meet these different needs of ours, so this paper is based on Bluetooth technology developed ZigBee technology.

2. WiFi module

WiFi is a wireless communication technology which is used by everyone and it is impossible to survive without it. Its principle is to convert wired network signals into wireless signals, through the wireless communication module as an intermediary, other terminal devices can be connected to WiFi for wireless network communication.The coverage of WiFi technology is generally not more than 100 meters and is very complex.smart module The transmission speed is 54 Mbps, the operating frequency is 2.4 ghz, and the transmission power is less than 100 MW.Compared with Bluetooth wireless communication, WiFi data security performance is poor. However, the invention of WiFi meets the needs of modern people and society, and its development prospect is very broad.

3. Bluetooth

Bluetooth is a wireless technology standard invented by Ericsson, a large telecommunication company at that time, in 1994. It realizes short-range wireless connection between fixed terminal devices, mobile terminal devices and personal LAN. Bluetooth wireless technology is very sophisticated and the device network speed is very fast, only 10 seconds. Integration and reliability are very high and the transmission rate is usually 1 Mbps. bluetooth is low cost, simple to install and suitable for short distance wireless communication technology.

4. Traditional digital radio

Traditional digital radio is a high-performance professional data transmission using DSP digital signal processing technology and software radio point technology. Digital radio can be understood as a communication medium with a wide range of applications, such as optical fiber and microwave. Digital radio transmits over long distances and adapts to a variety of complex environments with a transmission rate of 19.2 kbps. however, digital radios have high terminal equipment costs, high usage costs, and complex setups.
