Embodiment 1

[0029] Example 1, such as figure 1 , is the architecture of the network node in the present invention:

[0030] (1) Communication interface module

[0031] The USB interface voltage is 5V, and the ME6206 chip is used to convert the 5V interface voltage into 3.3V voltage, which supplies power to the microprocessor STM32 and the radio frequency chip nRF24L01, so that it can work normally. In addition, pins 2 and 3 of the USB interface are directly connected to the PA11 and PA12 ports of the microprocessor STM32 respectively, so as to realize the data exchange between the microprocessor STM32 and the USB interface.

[0032] (2). Processor module

[0033] The processor selects the STM32F103C8T6 of ST's STM32 series. The STM32 series of 32-bit Flash microcontrollers is based on the breakthrough ARM Cortex-M3 core. It provides a complete 32-bit product family that combines high performance, low power consumption, and low voltage while maintaining a high degree of integration and...

Abstract

The invention relates to a wireless data transmit-receive system, belongs to the field of wireless communication, and particularly relates to a transmit-receive system for multiple hop data of wireless Ad Hoc networks. The system comprises wireless network nodes and a routing protocol running on the wireless network nodes, wherein the wireless network nodes have the advantages of simplicity in use and portability through reasonable architecture design; the routing protocol is different from traditional demand routings; each node in the routing protocol has the routing function, is a transcendental routing, maintains all the information dynamically, and is long in transmission distance; and the unlimited extending of the communication distance can be achieved through adding relay nodes. Therefore, the system has a stronger practical value in the aspects of office, medical or intelligent home.

Description

technical field [0001] The invention relates to a wireless data sending and receiving system, which belongs to the field of wireless communication. In particular, it relates to a wireless ad hoc network multi-hop data sending and receiving system. Background technique [0002] Traditional PCs generally communicate with external controlled devices through serial ports or parallel ports, and their disadvantages are particularly prominent, requiring additional cables for connection. [0003] Although wireless control has gradually replaced wired control in the current market, most of the wireless transmission technologies have short transmission distances and a single supporting device, which hinders the application of wireless devices. [0004] To sum up, the existing communication systems between PCs and external devices currently on the market have the following disadvantages: [0005] 1) The shortcomings of communication systems connected by serial ports and parallel port...
