Multi-node distributed field intensity test system and method based on Bluetooth communication

Abstract

The invention provides a multi-node distributed field intensity test system and method based on Bluetooth communication. The test system comprises a distributed measuring unit and a terminal device having Bluetooth communication with the distributed measuring unit. The distributed measuring unit comprises N field intensity testers arranged at N test nodes respectively. Each field intensity tester is used for acquiring field intensity measurement data of the corresponding test node. The field intensity measurement data obtained by the N field intensity testers are gathered to a specified test node wirelessly and transmitted to the terminal device by the specified test node through Bluetooth communication. The terminal device is used for performing fitting processing on the measurement data and obtaining the field intensity spatial distribution state of an area to be tested. According to the test system and method, communication between all the electromagnetic field testers in the area and the remote terminal is achieved through a Bluetooth communication module, and the test system and method are easy and convenient to operate, reliable in communication and high in cost performance; electromagnetic field vector distribution of the area to be tested is obtained through a multi-point measurement and interpolation fitting mode, and thus data are complete, display is visualized, and the test system and method are convenient to use.
