Abstract

The invention discloses a production test system of large-scale short-distance wireless data transmission equipment, comprising radio-frequency performance testing equipment and at least one short-distance wireless data transmission equipment to be tested; the radio-frequency performance testing equipment comprises a microprocessor radio-frequency unit, and an RS232 serial communication unit and a matching radio-frequency receiving and transmitting circuit which are connected with the microprocessor radio-frequency unit; the microprocessor radio-frequency unit realizes data communication through the RS232 serial communication unit and a main controller, transmits and receives radio-frequency signals through the matching radio-frequency receiving and transmitting circuit; and the short-distance wireless data transmission equipment to be tested comprises a microprocessor radio-frequency module and a matching radio-frequency receiving and transmitting module which is connected with the microprocessor radio-frequency module, wherein the microprocessor radio-frequency module receives and transmits radio-frequency signals through the matching radio-frequency module. The production test system of the large-scale short-distance wireless data transmission equipment not only conveniently and accurately tests the radio-frequency pass rate of the short-distance wireless data transmission equipment, but also reduces the time and cost which are required by the production test.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system for production testing of short-distance wireless data transmission equipment. Background technique [0002] Short-distance wireless data transparent transmission is a cable replacement technology, which has been widely used in many fields such as industrial production, medical monitoring, and scientific research. Its appearance solves the annoyance of wired wiring due to environmental and conditional constraints, and has the advantages of low cost and easy portability. However, in the mass production and manufacturing process of short-distance wireless data transmission equipment, it is often necessary to carry out professional testing on each equipment that is about to leave the factory. A common practice is to set up an assembly line to conduct independent tests on each short-distance wireless data transmission device one by one. High-priced professio...
