Wireless sensor testing system and method

Abstract

The invention discloses a wireless sensor testing system and method. According to the system, a signal line control module is utilized to establish a dual-polarized antenna and communication antenna signal link from a wireless gateway, signal source equipment, a frequency spectrograph, a comprehensive tester and a network analyzer to a microwave anechoic chamber, so the wireless communication witha tested wireless sensor in the microwave darkroom is established through the dual-polarized antenna and the communication antenna; meanwhile, by means of control of the measurement and control host,the wireless communication between different analysis and test devices and the tested wireless sensor is achieved through the dual-polarized antenna and the communication antenna, so integration of test schemes of various types of existing wireless sensor devices is achieved, and the whole system and method are high in compatibility and high in automation degree. In the method provided by the invention, the precision of the measured signal receiving sensitivity of the wireless sensor is higher by utilizing six gradually reduced adjustment stepping values.

Description

technical field [0001] The invention relates to the technical field of wireless sensor testing, in particular to a wireless sensor testing system and a wireless sensor testing method using the system. Background technique [0002] The Internet of Things technology is developed on the basis of traditional technologies. Now the Internet of Things technology has been widely used in various industries.
