Abstract

The invention relates to a measuring system and method for a radio interference source of Internet of Things. The method comprises measuring a horizontal incoming wave direction of an interference signal; adjusting time references of devices to enable time marks of the devices to be uniform; determining an absolute horizontal position (xi, yi) of each device at a current moment; determining an RSSI value of a current maximal interference signal; determining an incoming wave direction of the current maximal interference signal; and according to the incoming wave direction of a maximal signal intensity and the absolute horizontal position of each device, calculating to obtain the position (x, y) of an interference source with the maximal signal intensity by y=tanbetanx+(yn-tanbetanxn) and y=tanbetamx+(ym-tanbetamxm). Compared with the prior art, the system and method of the invention have the advantages that the devices in the system are small in size, low in cost and low in power consumption; a plurality of devices in the system can be used for synchronous measurement, and the measuring method is rapid and simple; and a system error of the invention can be limited within + / -3 degrees, the requirements on measuring precision are met, the position of the interference source can be conveniently and rapidly located, and the measuring system and method are particularly suitable for the measurement and location of an interference source in a region with dense devices such as a plant.

Description

technical field [0001] The present invention generally relates to radio monitoring technology, and more particularly, relates to an Internet of Things radio interference source measurement system and method thereof. Background technique [0002] The rapid development of the Internet of Things, and most of the wireless systems of the Internet of Things use public frequency bands, and the intensive application of equipment and the intensification of electromagnetic environmental pollution further make the complete deployment and effective operation of the Internet of Things more difficult. In many occasions, especially dense cities To effectively identify the intensity of interference sources and locate the interference azimuth, a simple new solution is needed. [0003] The public Internet of Things uses more 2.4G frequency bands and 433M frequency bands. In addition, private power networks use 230M frequency bands and so on. Usually, the existing methods use omnidirectional ...
