Abstract

The invention discloses a wireless sensor testing system and method. The system uses a signal line control module to establish a dual-polarized antenna and The communication antenna signal link, and then establish wireless communication with the wireless sensor under test in the microwave anechoic chamber through the dual-polarization antenna and communication antenna, and at the same time use the control of the measurement and control host to realize the connection between different analysis test equipment and the wireless sensor under test The wireless communication is carried out through the dual-polarization antenna and the communication antenna, thereby realizing the integration of testing schemes of various types of wireless sensor equipment, and the whole system and method have strong compatibility and a high degree of automation. In the method of the present invention, the accuracy of the measured signal receiving sensitivity of the wireless sensor is higher by using six gradually smaller adjustment step values.

Description

Technical field [0001] The present invention relates to the field of wireless sensor testing, and more particularly to a wireless sensor test system and a wireless sensor test method using the system. Background technique [0002] Internet of Things technology is developed on the basis of traditional technology. Today, Internet technology has been widely used in all walks of life. However, in the field of Internet of Things test technology, there is still lack of large quantities of special test standards and test systems, especially Industrial Internet Wireless Terminal Test Field, most reference for the traditional electronic product test method, such as the radiation performance test of wireless sensors, is currently testing, including SRRC (State Radio RegulatoryCommission, National Radio Management Committee) certification launch Power test. [0003] At present, it is increasingly paying attention to the radio performance test of the wireless terminal of the mobile phone. Th...
