Research On Low Power Wireless Communication Technology In Short Range

The engine and the driving system are armored vehicle's important component. The real-time monitoring engine and driving system parameters can promptly know chariot's working condition, early find the problem, and correctly diagnose the malfunction. Therefore, it has the important significance for the chariot's logistics.Since the torque signal test has been affected by spatial and rotational characteristic of the transmission shaft, we cannot use the wired data transmission way. Considered the wireless communication is suitable especially for the locomotor equipment or the scene where people are not convenient arrive at, the real-time torque signal wireless communication system has been proposed in the paper.The paper has thoroughly analyzed the basic principle of wireless communication technology and microstrip antenna, elaborated the wireless data transmission system's design scheme, and designed wireless communication system based on the nRF2401 transceiver module. Since the narrow space of the rotation axis and harsh testing environment, the microstrip antenna has been designed, working in 2.4GHz center frequency. Since the serial and parallel interface have low data speed transmission and old circuit interface, the USB interface has been designed in order to realize high speed data transmission between the measured signal and the computer. The device has unique characteristics such as low power, simple structure, easy installation, high communication accuracy.
